Polyethylene plastiki ndiyo polyethylene sechinhu chikuru

Chinhu chikuru che polyethylene plastiki ndeye polyethylene. Yayo yakasvibirira ethylene inonyanya kuuya kubva kupetroleum kupaza uye kuputika, iyo ndeye petrochemical zvigadzirwa.

Polyethylene (PE) ndeimwe yemashanu makuru ekugadzira resin, uye ndiyo yakasiyana-siyana ine hukuru hukuru hwekugadzira uye huwandu hukuru hwekupinza vhoriyamu pakati pemasynthetic resin munyika yangu. Polyethylene inonyanya kukamurwa muzvikamu zvitatu: linear low-density polyethylene (LLDPE), yakaderera-density polyethylene (LDPE), uye yakakwirira-density polyethylene (HDPE).

kunyoresa

Purasitiki yekuputira, vest-style mabhegi epurasitiki, mabhegi epurasitiki egirosari, mabhodhoro evana, mapairi, mabhodhoro emvura, nezvimwe.

mamirire

PE yakapfava uye ine waxy manyorerwo ekubata. Kuenzaniswa nepurasitiki imwe chete, yakareruka muhuremu uye ine imwe dhigirii yekujeka. Painopisa, murazvo unova webhuruu.

Toxicity

Isiri-chepfu uye isingakuvadzi kumuviri wemunhu.

Material properties ye polyethylene plastiki

Corrosion resistance, yakanakisa kuvharirwa kwemagetsi (kunyanya high-frequency insulation), inogona kuve chlorinated, irradiated and modified, uye inogona kusimbiswa negirazi fibers. High-density polyethylene ine yakakwira kunyungudika, kusimba, kuoma uye kusimba, uye kunyura kwemvura. Zvakanaka magetsi emagetsi uye kurwisa kwemwaranzi; yakaderera-density polyethylene ine kunaka kupfava, kurebesa, kusimba kwesimba uye permeability; Ultra-yakakwirira molecular uremu polyethylene ine yakakwirira simba simba, kuneta kuramba uye kupfeka kuramba. High-density polyethylene yakakodzera Iyo inogona kushandiswa kugadzira corrosion-resistant parts uye insulating parts; yakaderera-density polyethylene yakakodzera kugadzira mafirimu, nezvimwewo; Ultra-yakakwirira molecular uremu polyethylene yakakodzera kugadzira kuvhunduka, kusapfeka uye kutapurirana zvikamu.
