Isesengura ry'imikorere y'ibikoresho fatizo bya pallet za pulasitiki

Pallet za pulasitiki muri iki gihe zikozwe ahanini muri HDPE, kandi urwego rutandukanye rwa HDPE rufite imiterere itandukanye. Imiterere yihariye ya HDPE ni uruvange rukwiye rw'ibintu bine by'ibanze: ubucucike, uburemere bwa molekile, ikwirakwizwa ry'uburemere bwa molekile n'inyongera. Hakoreshwa catalysts zitandukanye mu gukora polymers zihariye zihariye. Izi nyuguti zihuzwa kugira ngo hakorwe urwego rwa HDPE mu ntego zitandukanye, bigere ku buringanire mu mikorere.

Mu ikorwa ry’amapaleti ya pulasitiki, ubwiza bw’izi ngingo z’ingenzi bugira ingaruka kuri buri kimwe. Tuzi ko ethylene ari yo mashini nyamukuru ikoreshwa muri polyethylene, kandi izindi comonomer nke, nka 1-butene, 1-hexene cyangwa 1-octene, nazo zikunze gukoreshwa mu kunoza imiterere ya polymer. Kuri HDPE, ingano y’ibice bike byavuzwe haruguru muri rusange ntirenga 1%-2%. Kongeramo ibice bya comonomer bigabanya gato crystallinity ya polymer. Iri hinduka muri rusange ripimirwa n’ubucucike, kandi ubwinshi bufitanye isano n’ubucucike.

Mu by’ukuri, ubucucike butandukanye bwa HDPE buzatuma habaho itandukaniro rikomeye mu mikorere y’udupira twa pulasitiki twakozwe. Ubucucike bwa polyethylene iciriritse (MDPE) buri hagati ya 0.926 na 0.940g / CC. Hari ubwo uduce duto dushyira MDPE muri HDPE cyangwa LLDPE. Homopolymers zifite ubucucike bwinshi, gukomera, ubushobozi bwo kutarenza amazi n’aho zishongesha cyane.

Ubusanzwe mu gihe cyo gukora pallet za pulasitiki, hari inyongeramusaruro zimwe na zimwe zikenerwa kugira ngo habeho imikorere ikenewe. Imikoreshereze yihariye isaba inyongeramusaruro zihariye, nko kongeramo antioxydants kugira ngo hirindwe kwangirika kwa polymer mu gihe cyo gutunganya no gukumira oxidation y'umusaruro urangiye mu gihe cyo kuwukoresha. Inyongeramusaruro zirwanya static zikoreshwa mu byiciro byinshi byo gupfunyika kugira ngo bigabanye gufatana kw'umukungugu n'umwanda ku macupa cyangwa gupfunyika.

Byongeye kandi, kugira ngo amapaleti ya pulasitiki agire ubuziranenge, hagomba kwitabwaho cyane gupakira no kubika ibikoresho fatizo. Ubusanzwe iyo ubitse ibikoresho bya HDPE, biba ngombwa ko biba kure y’inkongi z’umuriro, bigashyirwa mu buryo bushyushye, kandi ububiko bugomba kuguma bwumye kandi busukuye. Birabujijwe kuvanga imyanda iyo ari yo yose, kandi birabujijwe cyane kugerwaho n’izuba n’imvura. Byongeye kandi, mu gihe cyo kubitwara, bigomba kubikwa mu modoka cyangwa mu kazu gasukuye, kumutse kandi gapfundikiye, kandi nta bintu bityaye nk’imisumari bigomba kwemererwa.
