LLDPE Mulch covering methods Plastic film mulching is a measure to cover the ground with agricultural plastic film. It can reduce the impact of raindrops, prevent erosion and crust formation, effectively reduce the evaporation of soil moisture, conserve soil moisture in dry days, and raise soil moisture after rain, promote the absorption, growth and development of crop water, and improve the util
Mulching film is the ground covering film, usually transparent or black PE film, also green and silver film, which is used for ground covering to improve soil temperature, maintain soil moisture, maintain soil structure, prevent pests from invading crops and diseases caused by some microorganisms, and promote plant growth. The mulch seems to be a thin layer, but it has a great effect. It can not
What are the categories and applications of PC sheet films? We know that PC film is an indispensable plastic construction product in our life. It can be found everywhere in our life. What are the classifications of PC film? What are the uses of PC film? Let me introduce to you next. PC film sheet can be divided into: 1. Transparent PC film sheet: printing grade, optical grade, electroplating gra
The Chinese name of PC sheet is polycarbonate, and the Chinese name of PET sheet is polyethylene terephthalate. Looking at the names, we can see that the materials of the two are different. Although they are all plastics, the essential difference is still very big. Next, we analyze the products of the two. PC sheet can be used to make Bai mineral water bottle and all other plastic beverage bottles
What is the difference between PE, PP and PC? Polyethylene is a kind of polymer which is polymerized by free radicals of vinyl monomers. Its English name is polyethylene, or PE for short. The synthetic raw material of PE comes from petroleum. Because of its abundant petroleum resources, its output ranks first. Polyethylene is a late industrialization, but the fastest-growing plastic variety. LDP
PC board Polycarbonate (PC), abbreviated as PC, is a kind of colorless and transparent qualitative thermoplastic material. Its name comes from its internal CO3 group. PP board: polypropylene (PP) board, (PP pure board, modified PP board, reinforced PP board, PP electrode) pure PP board: small density, easy to weld and process, superior chemical resistance, heat resistance and impact resistance,
Development status of PE sheet in China PE sheet is a kind of product with more use frequency at present. Its use efficiency is very high. The use efficiency is reflected by other forms, such as industrial application, etc. PE sheet is widely used in agricultural machinery, bulldozer, bulldozer and dumper row in Japan and Europe, because of the self-lubricating property of UHMWPE and the weight
Standard for polyethylene extruded PE sheet 1. Product classification PE sheet can be divided into two types according to the density: Low density plate: 0.92g/cm3 ~ 0.93g/cm3 High density plate: 0.96g/cm3 ~ 0.97g/cm3 2. Appearance The surface of the plate shall be smooth and flat without bubbles, cracks, obvious impurities and dents 3. Physical and mechanical properties Project unit index
