Plastic mesh tells about the performance and use of PPO plastics

PPO plastic , Chinese name: polyphenylene ether, English name: poly (phenyleneoxide).
PPO is one of the five general engineering plastics in the world. It has the advantages of high rigidity, high heat resistance, flame retardancy, high strength and excellent electrical properties. In addition, the polyether ether also has the advantages of abrasion resistance, non-toxicity, and pollution resistance. The dielectric constant and dielectric loss of PPO are among the smallest varieties in engineering plastics. They are almost independent of temperature and humidity and can be used in low, medium and high frequency electric fields. The load deformation temperature of PPO can reach above 190 °C, and the embrittlement temperature is -170 °C.
PPO plastic performance:
1, as white particles. Good comprehensive performance, can be used in 120 degree steam, good electrical insulation, low water absorption, but there is a tendency to stress cracking. Modified polyphenylene ether eliminates stress cracking.
2. Excellent electrical insulation and water resistance, good dimensional stability. Its dielectric properties rank first in plastics.
3. MPPO is a modified material prepared by blending PPO and HIPS. Currently, the materials on the market are all such materials.
4, has a higher heat resistance, glass transition temperature of 211 degrees, melting point of 268 degrees, heating to 330 degrees has a tendency to decompose, the higher the PPO content, the better the heat resistance, the heat distortion temperature can reach 190 degrees.
5, good flame retardancy, self-interest, and moderate flammability after mixing with HIPS. Lightweight, non-toxic for the food and pharmaceutical industries. It has poor resistance to optical rotation and will change color when used for a long time in the sun.
6, can be blended with ABS, HDPE, PPS, PA, HIPS, glass fiber, etc.
Use of PPO plastic:
1. It is suitable for the manufacture of heat-resistant parts, insulation parts, wear-reducing parts, transmission parts, medical and electronic parts.
2, can be used for gears, blades, valves and other parts used at higher temperatures, can be used instead of stainless steel.
3, can make screws, fasteners and connectors.
4. Electrical parts of motors, rotors, casings and transformers.

Exterior wall profile

Exterior Wall Tiles is mainly used for the decoration and protection of the building's exterior wall. Exterior wall tiles not only decorate the entire building, but also because of its acid and alkali resistance, physical and chemical properties of stability, to protect the wall has an important role, but also cold insulation. External walls can be stock sales, but also according to customer specifications and color of the special requirements of custom production.

 

 

How to choose exterior wall tiles

1, according to the level of External Wall Tile logo selection, the tile is divided into five levels, there are superior products, first-class products, second-class products, third-class products and other goods of the difference, due to larger spreads, to be carefully compared. In addition, in the purchase, but also pay attention to the logo on the tiles and packaging specifications, color number is consistent, product certification, trademark and quality control standard is clear.

2, according to the size of the outer wall of choice, standard size, unfavorable to the construction, better reflect the decorative effect. Good deviation of the specifications, paving the tidy uniform, brick straight, decorative effect is good. Dimensional error is greater than 0.5 mm, flatness greater than 0.1 mm of product, unfair to increase the difficulty of construction, while the decoration effect is poor. Whether the size meets the standard can be judged by the target. The bricks placed on a flat surface to see whether the four sides of the flat surface exactly match, at the same time, to see whether the four corners of the tile are right angles. Good newspaper no bump, bulging, Qiaojiao and other defects, the side of the error does not exceed 0.2-0.3 mm, the thickness of the error does not exceed 0.1 mm.

3, according to the exterior wall pattern selection, good ceramic tile pattern, pattern color clear and consistent, exquisite craftsmanship, no obvious leak color, dislocation, broken or inconsistent depth.

4, a careful observation of whether the color difference of the external wall tiles, color tiles, is directly related to the decoration effect. Not a batch of products, or the same batch may have color, therefore, in the purchase process, for each packaged product sampling comparison, the tiles placed in the same species and the same type of brick, observe its The degree of color difference, a good product color is small, the basic color tone between products, bright color uniform, brilliant, and poor product color larger, the product shades of color.

External wall size specifications

Exterior wall tiles are available in 25 * 25mm, 23 * 48mm, 45 * 45mm, 45 * 95mm, 45 * 145mm, 95 * 95mm, 100 * 100mm, 45 * 195mm, 100 * 200mm, 50 * 200mm, 60 * 240mm, 200 * 400mm and so on.

 

Advantages and disadvantages of exterior wall

Advantages of external wall:

1, the outer wall tile surface no matter whether it is shiny, and flat or rough, will have a different texture, its appearance is very decorative.

2, the external wall of the rugged, with good durability and texture, colorful and rich decorative effect, and has easy cleaning, fire, water, abrasion, corrosion resistance and low maintenance costs.

3, durability in the Outer Wall Tiles , which includes durable, dirt-resistant, scrub-resistant and so convenient, and its long service life.

Disadvantages of the external wall:

1, the outer wall tiles for the first time higher cost, higher paste requirements, construction difficult, but not easy to cause construction technology off the wounding, but also must be waterproof material to solve waterproofing problems.

2, from the environmental point of view, the outer wall tiles in the cleaning process with acid will cause pollution to the atmosphere.
