Hdpe quvur materiali haqida qisqacha ma'lumot
Jan 16, 2022
High density polyethylene, the English name is "High Density Polyethylene", referred to as "HDPE". HDPE is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin section. PE has excellent resistance to most household and industrial chemicals. Certain types of chemicals are chemically aggressive, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapour resistance for packaging applications. HDPE has good electrical properties, especially high insulation dielectric strength, making it very suitable for wires and cables. Medium to high molecular weight grades have excellent impact resistance at ambient temperatures and even as low as -40F.
HDPE 1956 yilda taqdim etilgan bo'lsa-da, plastmassa hali etuklikka erishmagan. Ushbu ko'p qirrali material doimiy ravishda yangi foydalanish va bozorlar uchun ishlab chiqilmoqda.
PE turli xil ishlov berish usullari bilan ishlab chiqarilishi mumkin. Bularga, masalan, qatlam ekstruziyasi, plyonkali ekstruziya, quvur yoki profil ekstruziyasi, puflash, qarshi kalıplama va aylanish kalıplama kiradi.
