Isesengura ryimikorere yibikoresho bya palasitike

Palasitike ya plastike muri iki gihe ikozwe cyane cyane na HDPE, kandi ibyiciro bitandukanye bya HDPE bifite imiterere itandukanye. Ibiranga umwihariko wa HDPE nuburyo bukwiye bwo guhuza ibintu bine byingenzi: ubucucike, uburemere bwa molekile, gukwirakwiza uburemere bwa molekile ninyongera. Catalizaires zitandukanye zikoreshwa mugukora progaramu yihariye yimikorere ya polymer. Izi mpinduka zahujwe no gutanga amanota ya HDPE kumpamvu zitandukanye, kugera kuburinganire mubikorwa.

Mubikorwa nyabyo no gutunganya palasitike ya plastike, ubwiza bwibihinduka nyamukuru bigira ingaruka kuri buriwese. Turabizi ko Ethylene aribikoresho byingenzi bya polyethylene, hamwe nabandi bantu bake, nka 1-butene, 1-hexene cyangwa 1-octene, nabyo bikoreshwa mugutezimbere polymer. Kuri HDPE, ibiri muri ba monomers bavuzwe haruguru muri rusange ntibirenza 1% -2%. Kwiyongera kwa comonomers bigabanya gato kristu ya polymer. Ihinduka risanzwe ripimwa nubucucike, kandi ubucucike bufitanye isano na kristu.

Mubyukuri, ubucucike butandukanye bwa HDPE buzatanga itandukaniro rigaragara mumikorere ya palitiki ya plastike yakozwe. Ubucucike bwa polyethylene yo hagati (MDPE) buva kuri 0.926 kugeza 0.940g / CC. Ibindi byiciro rimwe na rimwe bishyira MDPE nka HDPE cyangwa LLDPE. Homopolymers ifite ubucucike buri hejuru, gukomera, kudahinduka neza hamwe no gushonga cyane.

Mubisanzwe mugikorwa cyo gukora palasitike ya plastike, inyongeramusaruro zimwe na zimwe zirakenewe kugirango tumenye imikorere isabwa. Imikoreshereze yihariye isaba inyongeramusaruro zidasanzwe, nko kongeramo antioxydants kugirango wirinde kwangirika kwa polymer mugihe cyo gutunganya no gukumira okiside yibicuruzwa byarangiye mugihe cyo kuyikoresha. Antistatike yongeweho ikoreshwa mubyiciro byinshi byo gupakira kugirango ugabanye ivumbi numwanda kumacupa cyangwa gupakira.

Byongeye kandi, kugirango hamenyekane ubuziranenge bwa palasitike, hagomba kwitabwa cyane ku gupakira no kubika ibikoresho bibisi. Mubisanzwe iyo ubitse ibikoresho bya HDPE, birasabwa kuba kure yumuriro, bikingirwa, kandi ububiko bugomba guhora bwumye kandi bufite isuku. Birabujijwe rwose kuvanga umwanda uwo ari wo wose, kandi birabujijwe rwose guhura n'izuba n'imvura. Byongeye kandi, mugihe cyo gutwara, bigomba kubikwa mumodoka isukuye, yumye kandi itwikiriye, kandi ntakintu gikarishye nkimisumari.
