The precautions for the annealing process cover several aspects. Here are the specific precautions:

I. Control of Heating Temperature and Time

1. Temperature selection: The heating temperature should be determined based on the material of the flange connection problem solutions and the required annealing effect. For example, the annealing temperature for austenitic stainless steel is usually between 600 and 900°C, while the annealing temperature for ferritic stainless steel is lower, typically between 750 and 850°C.

2. Time Control: The duration of heat preservation will affect the annealing effect. It is necessary to select the appropriate heat preservation time based on the type, thickness of the stainless steel, and the required annealing effect. If the heat preservation time is too short, it may result in insufficient annealing, while if it is too long, it may lead to over-burning or coarse grains.

II. Management of Cooling Rate

1. Cooling method: The cooling process is equally important and requires strict control of the cooling rate to avoid the occurrence of secondary hardening. The cooling method can be air cooling, water cooling, or cooling with other media, depending on the type of stainless steel and the purpose of annealing.

2. Rate Control: In certain situations, such as when there is oxide scale and dirt on the surface, it is necessary to use a protective gas for oxygen-free annealing. If the cooling rate is too fast, it may cause the pipe to harden and become brittle, while if the cooling rate is too slow, it may lead to oxidation and decarburization of the pipe.

III. Use of Protective Atmosphere

1. Atmosphere selection: To prevent the surface of the pipe material from oxidizing and decarburizing, a protective atmosphere is usually adopted during the annealing process. Common protective atmospheres include inert gases (such as argon) or reducing gases (such as hydrogen).

2. Atmosphere purity: If hydrogen gas is used as the shielding gas, its purity should be above 99.99%. If there is excessive oxygen or moisture in the atmosphere, it will have an adverse effect on the pipe material.

IV. Equipment Selection and Inspection

1. Equipment Requirements: The annealing equipment should have excellent sealing performance and temperature control capabilities to ensure the stability and controllability of the annealing process.

2. Equipment Inspection: Before using the annealing equipment, a comprehensive inspection should be conducted to ensure that the heating elements, temperature sensors, control system, etc. are in good condition.

V. Operational Safety and Environmental Protection

1. Personal Protection: Operators should wear appropriate protective equipment, such as protective clothing, gloves, and masks, to prevent damage to their bodies from high temperatures and harmful gases.

2. Waste gas treatment: The waste gas generated during the annealing process should be properly treated before being discharged to meet environmental protection standards.

VI. Post-tempering Treatment and Inspection

1. Post-processing: After the annealing process is completed, the pipe material should undergo necessary cleaning and drying procedures to remove any residues and moisture on its surface.

2. Quality Inspection: After annealing, the flange connection problem solutions should undergo quality inspections, including appearance inspection, hardness testing, and grain size examination, etc., to ensure they meet the usage requirements.

In conclusion, for the solution to the flange connection problem, the annealing process needs to pay attention to multiple aspects such as temperature and time control during heating, management of cooling speed, use of protective atmosphere, selection and inspection of equipment, operation safety and environmental protection, as well as post-annealing treatment and testing. Only by strictly following these precautions can the effect and quality of the annealing process be ensured.

Industrial DPM export solutions use water as the dispersion medium. With its excellent environmental performance and outstanding construction and usage characteristics, it has become the mainstream film-forming raw material for building coatings (such as interior latex paint, exterior coatings, waterproof coatings, etc.). Its core features can be elaborated from aspects such as environmental friendliness, construction compatibility, performance, and application flexibility. The details are as follows:

1. Environmentally friendly and safe, in line with the trend of green building materials

Low VOC emissions: The industrial DPM export solutions replace the volatile organic solvents such as toluene and xylene in traditional solvent-based resins with water. The VOC (volatile organic compounds) content is usually ≤ 50g/L. Some high-end products can be as low as below 10g/L, far below the national building coating environmental protection standard (GB 18582-2020). During construction and use, there is no pungent odor, reducing the harm to the atmospheric environment and human health, and meeting the requirements of "green buildings" and "indoor air quality compliance".

No fire safety hazards: Water, as the dispersing medium, is non-flammable and non-explosive. Compared to solvent-based architectural coatings, the industrial DPM export solutions coatings do not require concerns about fire risks during storage, transportation, and construction. This reduces the safety management costs for storage and construction, and is particularly suitable for painting projects in densely populated areas such as residential buildings and office buildings.

Convenient wastewater treatment: The wastewater from tool cleaning during the construction process can be discharged in compliance with standards simply through simple sedimentation and filtration. There is no water pollution problem caused by organic solvents, which meets the strict environmental protection policies' requirements for industrial wastewater discharge and reduces the environmental governance pressure on coating enterprises.

2. Excellent construction performance, suitable for building coating scenarios

Flexible construction method: The industrial DPM export solutions coatings can be applied through various methods such as brushing, rolling, and spraying. The construction viscosity can be easily adjusted, and the leveling property is excellent (the leveling time is ≤ 30 minutes). There are no defects such as brush marks, run-off, or bubbles. Even non-professional construction personnel can operate it, making it suitable for different construction scenarios such as home decoration and large-scale construction projects.

Fast drying speed: Under normal temperature (25℃, relative humidity 60%), the surface drying time is only 1-2 hours, and the full drying time is ≤ 24 hours. It enables rapid re-coating (the next coat can be applied 4-6 hours later), significantly shortening the construction coating period. Especially suitable for projects affected by weather conditions such as exterior wall coating, reducing the risk of delays due to rainy days.

High adhesion to substrates: It can be directly applied to various building substrates such as concrete, cement mortar, gypsum board, wood, metal, etc., without the need for complex substrate pre-treatment (only cleaning, drying, and removing dust is required). It has strong adhesion (pull-off strength ≥ 1.5 MPa), and is not prone to peeling or falling off. It is suitable for coating requirements of different parts of buildings, such as walls, ceilings, and doors and windows.

Friendly to low-temperature construction: Some modified industrial dpm export solutions (such as those containing film-forming additives) can form a film normally at temperatures above 5℃. Compared to the minimum construction temperature of solvent-based coatings (above 10℃), these solutions meet the construction needs during the low-temperature periods in spring and autumn in northern China, thereby expanding the construction window period.

III. Comprehensive performance ensures the quality of building coating.

Excellent weather resistance: The acrylate groups contained in the molecular structure of industrial dpm export solutions have excellent resistance to ultraviolet degradation. After being used as exterior wall coatings, they can withstand natural environmental erosion such as wind, sun exposure, and rain. Even when exposed to the outdoors for a long time (5-8 years), they can still maintain color stability (color difference ΔE ≤ 2), intact paint film, without problems such as powdering, cracking, or fading. They are particularly suitable for outdoor scenarios such as high-rise building exteriors, bridges, and squares.

High resistance to abrasion and staining: After the paint film is cured, it forms a dense polymer film. The internal wall latex paint can withstand up to 10,000 times of rubbing. Daily stains (such as dust, juice, oil stains) can be removed directly with a damp cloth, without damaging the paint film. The surface of the exterior wall coating has a certain hydrophobicity (contact angle ≥ 90°), which can reduce the residue of stains after rain washing, keeping the wall clean and beautiful.

Good flexibility and crack resistance: By adjusting the glass transition temperature (Tg value) of the resin, the flexibility of the paint film can be customized (elongation at break ≥ 100%), which can adapt to the minor deformations caused by temperature changes and settlement of building substrates (such as concrete, gypsum board), avoiding cracking of the paint film. It is particularly suitable for the coating of new building walls (where shrinkage deformation is likely to occur) and the renovation of old buildings (where the base materials are prone to cracking).

Excellent anti-mildew and antibacterial performance: The industrial dpm export solutions coatings can be added with environmentally friendly anti-mildew agents (such as isothiazolinones), which can inhibit the growth of mold and bacteria in humid environments (such as bathrooms, basements, and the rainy seasons in the south). The paint film has no mold spots or odors, ensuring indoor air quality and meeting the hygiene requirements of residential, hospital, and school facilities.

Four. Flexible application, suitable for various painting requirements

Highly customizable functions: By adjusting the single-component ratios (such as adding methyl methacrylate, butyl acrylate, etc.) and adding functional additives (fire retardants, waterproof coatings, anti-static agents), multi-functional building coatings with fire resistance, waterproofing, anti-static properties, and thermal insulation can be developed. For instance, water-based acrylic waterproof coatings can be used for waterproofing projects in roofs, bathrooms, and basements, with no seams and excellent water resistance; fire-resistant water-based acrylic coatings can be used in steel structure buildings to enhance fire resistance.

The range of color and gloss options is extensive: The industrial dpm export solutions have good compatibility with pigments, allowing for the creation of thousands of colors with uniform and vibrant hues, which can meet the decoration needs of various architectural styles (modern minimalist, Chinese classical, European luxurious); the gloss can be adjusted according to requirements to matte, satin, semi-gloss, or high gloss, suitable for different scenarios such as interior walls (mainly matte for eye protection) and exterior walls (satin / semi-gloss, easy to clean).

Compatible with other materials: It can be compounded and modified with polyurethane, epoxy resin, silicone-acrylic resin, etc., or used in combination with various environmentally friendly additives such as water-based color pigments, film-forming additives, defoamers, etc., to further optimize the performance of the paint film (such as enhancing weather resistance, hardness, and adhesion), and develop high-end architectural coating products (such as imitation stone paint, real stone paint, artistic paint), thereby enhancing the grade and added value of architectural decoration.

V. High economic efficiency and cost-effectiveness, meeting the engineering cost requirements

Controllable raw material costs: The main raw materials of industrial dpm export solutions (acrylic monomer, water, initiator) have a wide source and mature production process. After large-scale production, the costs are relatively stable. Compared with high-end solvent-based resins (such as fluorocarbon resins) and silicone acrylic resins, it has obvious cost advantages and is suitable for the coating needs of large-scale construction projects.

Low construction and maintenance costs: During the construction process, no additional explosion-proof equipment or ventilation equipment is required, and tool cleaning only requires water, thereby reducing the auxiliary costs of construction. The paint film has a long service life (5-10 years for interior walls, 8-15 years for exterior walls), and during later maintenance, only local repairs are needed, without the need for overall renovation, significantly reducing the long-term maintenance costs of building coating.

In conclusion, industrial dpm export solutions, with their core features of environmental protection and safety, convenient construction, comprehensive performance, and high cost-effectiveness, perfectly meet the processing and application requirements of architectural coatings. They have become a key material for the construction industry to achieve green and low-carbon transformation and improve coating quality. They are widely used in the interior and exterior wall decoration and functional protection of various buildings such as residences, office buildings, bridges, and stadiums.

In the 21st century, hospitals have put forward new requirements for endoscopes, such as portability, miniaturization, and intelligence. Inspired by industrial portable endoscopes, medical portable endoscope systems have emerged. Currently, many companies at home and abroad have developed different products, but due to the early stage of research and development, the constituent modules have not yet formed a unified standard, and there are still some problems.

In the industrial field, portable endoscopes were first used for internal inspection and flaw detection of components. They consist of a handheld terminal, signal connection cables, camera modules, etc., and are convenient for engineers to carry and use. With the development of technology, their functions have gradually improved and the technology has become more mature. However, industrial portable endoscopes do not have high requirements for pixel, real-time image transmission and lighting sources.

Analysis of Key Technologies for Medical Portable Endoscopes

Power supply module

Medical portable endoscopes need to be powered by batteries. Currently, in China, large-capacity lithium batteries are mostly used. Due to the limitation of size, the battery capacity is limited, and the battery life is generally 2 to 4 hours. By using power management chips, interference in the circuit can be eliminated, and power can be supplied to all modules of the system. Low-power electronic components and circuit optimization reduce the system's power consumption, providing conditions for solar charging. Some products can be charged by solar panels or 220V mains electricity.

Front-end collection module

Front-end adapter: The medical portable endoscope is connected to various endoscopes through the adapter. It has a lens group inside to ensure complete, distortion-free and accurate focal length of the image. The lens group designs of different manufacturers are different. Aspherical lenses can optimize image quality and reduce size. The design needs to consider various factors and determine the parameter indicators according to the optical characteristics of different endoscope interfaces.

Image sensor: The image sensor converts optical signals into electrical signals. There are mainly two types: CCD and CMOS. Medical portable endoscopes mostly adopt CMOS sensors, as CMOS sensors have relatively lower costs. With the continuous advancement of technology, the performance of CMOS sensors keeps improving while their costs gradually decrease. This enables medical portable endoscopes to be launched onto the market at more affordable prices, benefiting more medical institutions and patients. Especially in some areas with limited resources, low-cost Disposable plasma surgical electrode equipment can bring new opportunities for the development of local medical services.
