Introduction to the products of shenzhen xi cheng PP (polypropylene)
PP board (rod, tube) is a semi-crystalline material. Copolymer of PP materials with low heat distortion temperature (100 ℃), low transparency and gloss, low rigidity, but has a stronger impact strength. The strength of PP increases with the increase of ethylene content.
Characteristics of PP board
The PP board has the characteristics of light weight, uniform thickness, smooth surface, good heat resistance, high mechanical strength, excellent chemical stability and electric insulating and non-toxic characteristics.
PP board is widely used in chemical containers, machinery, electronics, electronics, food packaging, medicine, decoration and water treatment
PP board practical temperature can reach 100 degrees, acid and alkali resistant equipment, environmental equipment, waste water, waste gas emissions equipment, washing tower, clean room, semiconductor factory and related industrial equipment, and optimization of manufacturing plastic water tank material, including PP thick plate is widely used in drawing, punching plate, etc.
How to identify the quality of PP board
1. Touch with the hand to see if the surface is smooth and smooth, and the color particles are uniformly bright. At present, the wholesale market of PP sheet metal is mainly white and transparent.
Generally, the recycling is not white, so we usually think that the color white is good, in fact, this statement is also one-sided. Due to the rapid updating of the technology, the color of pp sheet is not easy to see the good and poor. But it can be touched by hand, and the coarser surface particles may be adulterated with other impurities.
2. Smell the smell, good PP plate is not smell, bad smell.
3, use the hand to pinch, PP plank material has very strong hardness, if can knead to transform easily, that is not good.
4, bad, good PP sheet material, resilience is better, it is easy to be smashed of course is not good.
5. It's good to see this method on fire. If the material is mixed with other recycled materials, it will emit black smoke and a pungent smell. Good materials will not have black smoke after burning. The liquid will also be clean.Shenzhen city Xicheng Plastic Co., Ltd. Located in Bao an District, Shenzhen, The company mainly produces waste gas treatment equipment, ventilation equipment, exhaust tower, activated carbon tower, washing tower, PP board, PP pipe, PP wind valve, PP elbow, and other ventilation accessories.
