Gukuramo plastike, nka UPVC (polyvinyl chloride igoye) imyirondoro cyangwa ibicuruzwa biva mu miyoboro, bigizwe ahanini no kuvanga, gutunganya ibicuruzwa, gushushanya, kubikuramo, no gukata ibisigazwa bya PVC nibindi byongeweho.Ibintu bigira ingaruka kumikorere yibicuruzwa bikubiyemo intambwe zose mubikorwa byo gukora.Buri ntambwe irakorana kandi ikagira ingaruka kuri media binyuze mubitangazamakuru byibicuruzwa.Ikibazo kimwe gishobora kwishyurwa nizindi ntambwe murwego runaka, buri ntambwe rero iba ibinyabuzima.Muri byo, ibikoresho fatizo, ibikoresho bya formulaire hamwe nubuhanga bwo gukora nibintu byingenzi mubikorwa byo gukuramo plastike, bigira ingaruka kuburyo butaziguye ubwiza nibisohoka mububiko.Iyi ngingo yibanze ku ngaruka ziterwa no gusohora hifashishijwe ibikoresho byo gukuramo ibikoresho fatizo.
Muri rusange, PVCibicuruzwa koresha inyongera zikurikira kugirango ukore inzira yo gukuramo:
1.PVC resin:
Polyvinyl chloride, yitwa PVC mu Cyongereza, ni iya gatatu yakozwe na plasitiki ya polymerike ikorwa cyane ku isi (nyuma ya polyethylene na polypropilene).PVC yahoze ikorwa cyane muri plastiki rusange-yisi yose kandi yarakoreshejwe cyane.Hariho ubwoko bubiri bwa PVC: bukomeye (rimwe na rimwe mu magambo ahinnye nka RPVC) kandi byoroshye.Rigid polyvinyl chloride ikoreshwa mumiyoboro yubwubatsi, inzugi nidirishya.Ikoreshwa kandi mu gukora amacupa ya pulasitike, gupakira, banki cyangwa amakarita yabanyamuryango.Ongeramo plasitike ituma PVC yoroshye kandi yoroshye.Irashobora gukoreshwa mu miyoboro, kubika insinga, hasi, ibyapa, inyandiko za fonografi, ibicuruzwa byaka umuriro hamwe nabasimbuye reberi.
stabilisateur:
Kuberako PVC resin ari resin itumva ubushyuhe, itangira kwangirika cyane mugihe ubushyuhe bugeze kuri 90 kugeza 130 ° C, kurekura HCL idahindagurika kandi bigatuma resin ihinduka ibara ry'umuhondo.Mugihe ubushyuhe buzamutse, ibara ryibisigara rihinduka umwijima kandi ibintu bifatika & imiti yibicuruzwa bigabanuka.Usibye kunoza uburyo bwo kubyaza umusaruro ibikoresho fatizo bya resin, gukemura ikibazo cyo kwangirika bikubiyemo cyane cyane kongeramo stabilisateur kuri PVC kugirango yinjize kandi yanduze gaze ya HCL no gukuraho ingaruka zayo zo kwangirika.Sisitemu ikoreshwa cyane muri sisitemu irimo: imyunyu ngugu, organotine, amasabune yicyuma hamwe nubutaka budasanzwe.
Amavuta (ibishashara bya PE cyangwa Paraffin):
Ubwoko bumwe bwinyongera kugirango butezimbere amavuta kandi ugabanye interineti.Ukurikije imikorere, bagabanijwemo amavuta yo hanze, amavuta yimbere hamwe nimbere & hanze.Amavuta yo hanze arashobora kugabanya ubushyamirane buri hagati yubutaka nicyuma kugirango birinde ibikoresho bya UPVC kwizirika kuri barriel na screw nyuma ya plastike.Amavuta y'imbere arashobora kugabanya ubushyamirane buri hagati yibintu, bigabanya ubumwe hagati ya molekile kandi bikagabanya ubukonje bwashonga.Gukoresha amavuta bigira ingaruka zikomeye mukugabanya imitwaro ya screw, kugabanya ubushyuhe bwimisatsi, no kongera umusaruro.Igishushanyo mbonera cyo gusiga ni ngombwa cyane.
Kuzuza ibikoresho:
Mu rwego rwo kunoza ubukana n’ubukomezi bwibicuruzwa, kugabanya ibicuruzwa biva mu mahanga, no kugabanya ibiciro by’ibikoresho fatizo, abuzuza nka CaCO 3 bakunze kongerwaho umusaruro w’ibicuruzwa bya UPVC.
Guhindura gutunganya (ACR):
Intego nyamukuru nugutezimbere imikorere yibikoresho, kwihutisha plastike ya resin ya PVC, no kunoza amazi, guhindura ubushyuhe hamwe nuburabyo bwibicuruzwa.
Guhindura ingaruka:
Intego nyamukuru nugutezimbere ingaruka ziterwa nibicuruzwa, kunoza ubukana bwibicuruzwa, no kunoza ingaruka za plastike.Impinduka zikoreshwa cyane muri UPVC ni CPE (chlorine polyethylene) hamwe no guhindura ingaruka za acrylate.
Uburyo bwa plastike bwibikoresho byo gukuramo plastike ningaruka zibigize amata kuri yo:
Hano hari ibikoresho byinshi byo kubumba plastike.Ibyingenzi bikoreshwa mugukuramo ibicuruzwa bikomeye bya UPVC ni ukurwanya-kuzunguruka twin-screw extrudersconical twin screw extruder.Ibikurikira biraganira cyane cyane kuburyo bwa plastisike yubusanzwe bukoreshwa mugusohora ibicuruzwa bya UPVC.
