Loluphi uhlobo lweplastiki iPE?
I-PE (i-Polyethylene, i-Polyethylene) yenye yezona zinto ziqhelekileyo ze-thermoplastics ezisetyenziswa kwishishini lemichiza. Isetyenziswa kakhulu kwiinkalo ezahlukeneyo kwaye iye yaba yinto ekhethwayo kumashishini amaninzi ngenxa yeempawu zayo ezibalaseleyo kunye noqoqosho. Kweli nqaku, siya kuhlalutya ngokweenkcukacha iintlobo zeplastiki ze-PE, iipropathi zazo kunye nezicelo zazo eziphambili ukukunceda ukuba uqonde ngcono le nto ibalulekileyo yeplastiki.
Isishwankathelo esiSisiseko sePlastiki yePE
Iplastiki ye-PE (i-polyethylene) yinto yepolymer eveliswa yi-polymerization ye-ethylene monomer. Ngokuxhomekeke kuxinzelelo kunye nobushushu ngexesha lenkqubo ye-polymerisation, iiplastiki ze-PE zinokuhlelwa kwiindidi ezininzi eziphambili ezifana ne-polyethylene ephantsi (LDPE), i-polyethylene ephezulu (i-HDPE) kunye ne-linear low density polyethylene (LLDPE). Uhlobo ngalunye lweplastiki ye-PE lunolwakhiwo olukhethekileyo kunye neempawu kwiimeko ezahlukeneyo zesicelo.
Iindidi zeeplastiki ze-PE kunye neempawu zazo
IPolyethylene yoXinano oluPhantsi (LDPE)
I-LDPE iveliswa yi-polymerisation ephezulu yoxinzelelo lwe-ethylene, equkethe amatyathanga amaninzi kwisakhiwo sayo kwaye ngoko ke ibonisa iqondo eliphantsi le-crystallinity.LDPE ibonakala ngokuthambile kwayo, ukuqina, ukungafihli kunye nokuchasana kwempembelelo, kwaye isetyenziswa ngokuqhelekileyo kwimveliso yeefilimu, iingxowa zeplastiki kunye nokupakishwa kokutya. Ngaphandle kwamandla aphantsi kunye nokuqina kwayo, ukuqhubekeka kakuhle kwe-LDPE kunye neendleko eziphantsi ziyenza ibaluleke kwizinto zokupakisha.

Uxinaniso oluPhezulu lwePolyethylene (HDPE)
I-HDPE ifakwe i-polymerised phantsi koxinzelelo oluphantsi kwaye inomlinganiselo othe kratya we-molecular structure, okhokelela kwi-crystallinity ephezulu kunye nobuninzi. Ezi zakhiwo zenza i-HDPE isetyenziswe ngokubanzi ekwenzeni imibhobho, izikhongozeli, iibhotile kunye namacandelo achasene neekhemikhali, phakathi kwabanye.

I-Linear Low Density Polyethylene (LLDPE)
I-LLDPE yenziwe nge-co-polymerising polyethylene kunye nezixa ezincinci ze-copolymer monomers (umzekelo, i-butene, i-hexene) kuxinzelelo oluphantsi. Idibanisa ukuguquguquka kwe-LDPE kunye namandla e-HDPE, ngelixa ibonisa ukuchasana kwempembelelo ephezulu kunye nokwelula.

Iindawo ezingundoqo zokusetyenziswa kweeplastiki ze-PE
Ngenxa yeendidi kunye nokusebenza okuphezulu kweeplastiki ze-PE, iindawo zokusetyenziswa kwayo zibanzi kakhulu. Kwishishini lokupakisha, iiplastiki ze-PE zihlala zisetyenziselwa ukwenza iintlobo ezahlukeneyo zeefilimu zeplastiki, iingxowa kunye nezikhongozeli zokupakisha. Kwintsimi yeemibhobho, i-HDPE isetyenziswa ngokuqhelekileyo ekuveliseni ukunikezelwa kwamanzi kunye nemibhobho yokuhambisa amanzi, imibhobho yegesi, njl. Kwiimveliso zasekhaya, iiplastiki ze-PE zisetyenziswa ngokubanzi ukuvelisa iibhotile, izitya kunye nezinye iimveliso zeplastiki. Kwintsimi yezolimo, i-LLDPE kunye ne-LDPE zisetyenziswa ngokubanzi ukwenza iifilimu zezolimo ukubonelela ngokhuseleko lwezityalo kunye nokugquma komhlaba.
Ukushwankathela
Yintoni iplastiki ye-PE? Kuyinto eguquguqukayo, eyongayo kwaye isetyenziswa ngokubanzi i-thermoplastic. Ngokuqonda iintlobo ezahlukeneyo zeplastiki ye-PE kunye neempawu zabo, amashishini kunye nabathengi banokukhetha ngcono izinto ezifanelekileyo kwiimfuno zabo. Ukusuka kwipakethe kunye neetyhubhu ukuya kwiimveliso zasekhaya, iplastiki ye-PE idlala indima ebalulekileyo kubomi banamhlanje kunye nezibonelelo zayo ezizodwa. Ukuba udidekile xa ukhetha izinto zeplastiki, sinethemba lokuba eli nqaku lingakunika ulwazi olubalulekileyo lwereferensi.
