Isingxobo esilukiweyo sisingxobo seplastiki esisetyenziswa ngokuqhelekileyo, esenziwe ikakhulu ngepolyethylene okanye i-polypropylene, yolulwe ibe yisilika emcaba, emva koko ilukwe, ilukwe kwaye ifakwe engxoweni.Ngenxa yokuba amandla, ukuqina kunye nokucaca kwe-polypropylene kungcono kune-polyethylene, ngoko ke isetyenziswe ngakumbi, indima yeengxowa ezilukiweyo nazo zibanzi.Ngokuqhelekileyo zisetyenziswa njengeengxowa zokupakisha kwaye zingasetyenziselwa ukupakisha iimveliso zoshishino kunye nezolimo.Ukutya, njl. Ngaphandle koko, ukhenketho.Iingxowa ezilukiweyo zikwasetyenziselwa ukulwa nezikhukhula kunye noncedo lwentlekele.
Ibhegi ephothiweyo, ekwabizwa ngokuba yi-snakeskin bag, luhlobo lwengxowa yeplastiki, esetyenziselwa ukupakisha, ngoko yintoni impahla yeplastiki elukiweyo?Ngokubanzi, iibhegi ezilukiweyo zinemathiriyeli ekrwada ezimbini:
1. Polyethylene
Ikwabizwa ngokuba yi-PE iplastiki yintlaka ye-thermoplastic eyenziwe nge-ethylene polymerization.Ingxowa ephothiweyo yeplastiki yePolyethylene inomsebenzi olungileyo, kodwa ipolyethylene inovelwano kuxinzelelo lokusingqongileyo, ukunganyangeki kobushushu kunye nokuguga, ngoko ke ayisetyenziswa kangako eTshayina.
2. Polypropylene
Ngokuqhelekileyo, uninzi lweengxowa ezilukiweyo eTshayina zenziwe ngepolypropylene.I-Polypropylene (PP) yintlaka ye-thermoplastic eyenziwe kwi-acrylic polymer enezinto ze-isotropic.Random kwaye intergauge uqwalaselo ezintathu, amandla ayo.Ukuqina kunye nokungafihli ngcono kune-polyethylene, kwaye inokuguqulwa kwaye yongezwe i-antioxidants ukoyisa ukumelana nefuthe lobushushu obuphantsi, iintsilelo zokuguga ezilula.
Kwiimveliso zeplastiki, i-braid yeplastiki luhlobo lwezixhobo eziguquguqukayo ezinamandla amakhulu okuqhawula, okuhambelana nesakhiwo sayo se-molecular, i-crystallinity, isikhokelo soyilo kunye nohlobo olongezelelweyo.Ukuba i-braid yeplastiki ilinganiswa ngamandla athile (amandla / umxhuzulane okhethekileyo), iphezulu okanye isondele kwizinto zetsimbi.
Kwiqondo lobushushu begumbi, ilaphu leplastiki eliphothiweyo lixhathisa ngokupheleleyo kukhukuliseko lwamanzi, kwaye izinga lokufunxa kwamanzi lingaphantsi kwe-0 kwiiyure ezingama-24.01%.Ukungena kwamanzi nako kuphantsi kakhulu.Kwiqondo lokushisa eliphantsi, liba lukhuni.Iintsimbi zeplastiki azigundi.
