Ni izihe mpamvu zituma habaho uduheri mu gice cy’amabati ya pulasitiki afite ifuro?

Impamvu imwe ni uko imbaraga zo gushonga ubwazo ziba nke cyane, bigatuma uduheri twibasira inyuma;

Impamvu ya kabiri ni uko bitewe n'umuvuduko muke ukikije aho amazi ashongeshwa, uduce duto two mu gace turakura kandi imbaraga zatwo zigacika intege, bigatuma uduce duto dutangira imbere tujya inyuma. Mu mikorere y'umusaruro, nta tandukaniro riri hagati y'imikorere ibiri, kandi birashoboka ko tubaho icyarimwe. Uduce twinshi duterwa no kwaguka gukabije kw'uduce duto two mu gace, bigatuma imbaraga zo gushongeshwa zigabanuka.

Muri make, gukora udupira mu mpapuro za pulasitiki zifuro bikubiyemo ahanini ibi bikurikira:

Ikorwa rya PVC foam board muri rusange rikoresha uburyo butatu butandukanye bwo kugenzura ifuro rya PVC: ubwoko bwo gushyushya, ubwoko bwa endothermic, cyangwa ubwoko bwa endothermic na exothermic composite equilibrium. Ubushyuhe bwo kubora bwa PVC foam regulator ni bwinshi, bugera kuri 232 ℃, burenga cyane ubushyuhe bwo gutunganya PVC. Mu kuyikoresha, ubushyuhe bwo kubora bugomba kugabanuka. Kubwibyo, mu gihe cyo kugenzura ifuro ryibikoresho bya PVC, muri rusange hatoranywa uburyo bwo kugenzura ifuro rya PVC. Ubu bwoko bwa PVC foam regulator bufite igipimo cyo hejuru cyo gusohora ifuro, hafi 190-260ml/g, umuvuduko wo kubora vuba, no kurekura ubushyuhe bwinshi. Ariko, igihe cyo gusohora ifuro ni gito kandi igitunguranye nacyo kiba gikomeye. Kubwibyo, iyo ingano ya PVC foam agent ari nyinshi cyane kandi imyuka ikaba myinshi cyane, bizatuma igitutu kiri imbere mu ifuro cyiyongera vuba, ingano y'ifuro ikure cyane, kandi gazi izarekurwa vuba, bigatera kwangirika kw'imiterere y'ifuro, ikwirakwizwa ry'ifuro ritaringaniye, ndetse no kurema imiterere y'uturemangingo dufunguye, bizatanga ifuro rinini n'imyanda mu gace. Mu gukora ibikoresho bya pulasitiki bifite ifuro, ibikoresho bigenzura ifuro rya PVC byo mu bwoko bwa exothermic ntibigomba gukoreshwa byonyine, ahubwo bigomba gukoreshwa hamwe n'ibikoresho bigabanya ifuro rya endothermic cyangwa hamwe n'ibikoresho bigabanya ubushyuhe n'ibinyabutabire bivanze n'ibinyabutabire. Ibikoresho bigabanya ifuro - sodium bicarbonate (NaHCO3) ni ibikoresho bigabanya ifuro rya endothermic. Nubwo igipimo cyo gukura ifuro ari gito, igihe cyo gukura ifuro ni kirekire. Iyo bivanze n'ibikoresho bigenzura ifuro rya PVC, bishobora kugira uruhare rwuzuzanya kandi rungana. Ibikoresho bigenzura ifuro rya PVC byongerera ubushobozi bwo gukora ifuro rya endothermic, mu gihe ibikoresho bigenzura ifuro rya PVC byo mu bwoko bwa exothermic bikonjesha icya mbere, bigatuza ibora ryacyo, kandi bigatunganya irekurwa rya gazi, bikabuza kwangirika imbere kw'amasahani manini, bikagabanya imvura y'ibisigazwa, kandi bikagira ingaruka nziza.

Kubera ko nta ngaruka ku gipimo cy’ifuro, birakwiye kongeramo izindi mashini zigenzura ifuro rya PVC kugira ngo zisimbuze zimwe mu mashini zikuraho ifuro, kugira ngo hagabanywe guturika guterwa no kongeramo izindi mashini zikuraho ifuro.
