ntchito

Chitoliro cha HDPE ndi choyenera kugwiritsa ntchito madzi amchere.Zomwe zimapangidwira mapaipi apamwamba kwambiri a polyethylene amalola kugwiritsa ntchito m'malo osiyanasiyana.Chitoliro cha pulasitiki choterechi chingagwiritsidwe ntchito pobwezeretsanso madzi, zimbudzi, ndi madzi amchere.Kutalika kwa moyo wautali ndi chimodzi mwazinthu zabwino kwambiri zopangira mapaipi a polyethylene.

Pawiri-khoma malata chitoliro ndi mkulu kachulukidwe polyethylene monga zopangira za mtundu watsopano wa machubu opepuka zitsulo, ndi kuwala kulemera mkulu kuthamanga kukaniza toughness ndi wabwino Kumanga ndi makhalidwe mofulumira moyo wautali utumiki, kwambiri khoma kapangidwe kamangidwe, poyerekeza ndi dongosolo lina la chitoliro, mtengo wafupika kwambiri Ndipo chifukwa kugwirizana ndi yabwino ndi yodalirika, chimagwiritsidwa ntchito kunyumba ndi kunja Chiwerengero chachikulu cha njira konkire chitoliro ndi chitsulo chitoliro.

HDPE iwiri khoma mvuto, chubu khoma wapangidwa ndi zigawo ziwiri za kapangidwe mkati ndi kunja, kulemera kwa chigawo chilichonse mu wosanjikiza akunja ndi:

Zithunzi za HDPEmkulu osalimba polyethylene utomoni50-80,

m'munsi mwapadera 15-30,

maziko apadera osinthidwa 10 ~ 25,

hygroscopic maziko 2 ~ 5,

mtundu maziko 1 ~ 3;

Kulemera kwa chigawo chilichonse chamkati ndi:

HDPE mkulu osalimba polyethylene utomoni 50 ~ 80,

metallocene liniya otsika osalimba polyethylene 15 ~ 30,

mbuye wapadera 20 ~ 45,

hygroscopic master 1-3,

mtundu master 1 ~ 3
