When some friends use various materials to decorate, it is better to try this black PP sheet . What kind of material is black pp sheet? What is the effect of black pp sheet and what is the structure of this black pp sheet? What are the introductions, the characteristics of the black pp plate and the scope of use, if the black pp plate is absolutely good, then what is the black pp plate installation method.
First, the introduction of black pp plate
1. The PP board is a semi-crystalline material. It is harder and has a higher melting point than PE. Since the PP temperature of the homopolymer type is very brittle when it is higher than 0 ° C, many commercial PP materials are random copolymers of 1 to 4% ethylene or a clamp copolymer of a higher ratio of ethylene. The copolymer type PP material has a low heat distortion temperature (100 ° C), low transparency, low gloss, low rigidity, but has a stronger impact strength.
2. The strength of PP increases with increasing ethylene content. The Vicat softening temperature of PP is 150 °C. Due to the high degree of crystallinity, this material has excellent surface stiffness and scratch resistance. There is no environmental stress cracking problem in PP.
3. Generally, PP is modified by adding glass fiber, metal additive or thermoplastic rubber. The flow rate of PP has a MFR ranging from 1 to 40. Low MFR PP materials have better impact resistance but lower elongation.
4. For materials of the same MFR, the strength of the copolymer type is higher than that of the homopolymer type. Due to crystallization, the shrinkage rate of PP is quite high, generally 1.8 to 2.5%. And the direction uniformity of shrinkage is much better than materials such as PE-HD. The addition of 30% glass additive can reduce the shrinkage to 0.7%. Both the homopolymer type and the copolymer type PP materials have excellent moisture absorption resistance, acid and alkali corrosion resistance, and solubility resistance.
Second, the application range of black pp plate
1. Acid and alkali resistant equipment, environmental protection equipment, waste water, exhaust gas discharge equipment, washing tower, clean room, semiconductor factory and related industrial equipment, is also the preferred material for manufacturing plastic water tanks, among which PP thick plates are widely used in stamping plates. , rushing mattress boards, etc.
2. Polypropylene (PP) extruded sheet is a plastic sheet made by adding PP resin into various functional additives through extrusion, calendering, cooling, cutting and other processes.
Third, black pp plate features
1. PP extruded sheet has the characteristics of light weight, uniform thickness, smooth surface, good heat resistance, high mechanical strength, excellent chemical stability, electrical insulation and non-toxicity.
2, PP board is widely used in chemical containers, machinery, electronics, electrical appliances, food packaging, medicine, decoration and water treatment. The practical temperature of the PP plate can reach 100 degrees.
Fourth, black pp plate installation method
1, pp board welding pre-treatment work. Before the pp board is welded, the pp board needs to be wiped clean to ensure that the welded parts of the pp board are dry, free from dust and grease. In addition, the edge of the pp board needs to be chamfered.
2, pp board welding. When the pp board starts to weld, it is necessary to clamp the two pp boards with the clamp to ensure the correct welding position of the pp board. When welding, the welding staff is required to take the welding work in one hand and press the welding rod in the weld area with one hand. It must be said that the quality of the pp plate welding depends on the welding personnel's control of the welding pressure.
3. Work after welding. After the pp plate is welded, the welding gun needs to be placed on the workbench, then the power supply is cut off, the work site is cleaned, and the welding tools and materials are finally placed, and the materials are returned to the original place.
Is the composition of our black pp sheet very special? The difference between other black materials is the characteristics of black pp sheet and the range of use. Then we have some installation methods for this black pp sheet. Everyone knows, friends. Also want to know more about decoration information, you can continue to pay attention to our decoration home network.
