Uburyo bwo kunoza kurwanya ubukonje bwa pvc firime yoroshye

Nkibice byingenzi bya PVC ibicuruzwa byoroshye, plastistizer bifite uruhare runini mubikorwa bya PVC ibicuruzwa byoroshye. Niba PVC ibicuruzwa byoroshye (PVC ubukonje bwububiko bwumuryango) birasabwa gukoreshwa mubushyuhe buke, plastizizer hamwe no kurwanya ubushyuhe bwiza bigomba gutoranywa. Kugeza ubu ikoreshwa nka plastisti irwanya ubukonje bukonje cyane aside dibasic, acide ya Phthalica

Nkuko twese tubizi, yaba PVC amakara ya plastike cyangwa pvc ibicuruzwa byoroshye nkamasabiri ya PVC, bazakomera mu gihe cy'itumba. Umubare wa plastizi ukwiye kwiyongera cyane, kandi abashimusi barwanya ubukonje barashobora kongerwaho uko bikwiye. DAA (Dioctyl asobanura), Dida (Dodecyl asobanura), Docyi (Dioctyl Azelate), Dos (Dioctyl Sebacote) ni ubwoko burwanya-ubukonje bukabije. Kuva ihuza rya plastizi rusange irwanya ubukonje hamwe na PVC ntabwo aribyiza cyane, mubyukuri, birashobora gukoreshwa nka plastistier gusa kugirango utezimbere ikonje, kandi dosage yacyo ni 5 ~ 20% ya plastistifer nkuru.

Ubushakashatsi bwerekanye ko guhuza plastisting clastisting cy'ubukonje na hexamethyl ya hexamethyl birashobora kunoza ubukana bukabije no kuramba-ubushyuhe bwa firime ya PVC. Nubwo hanamethyl thephohoric ubwato ntabwo ari plastistizer ikonje, irashobora kugabanya neza ingingo zikonje kandi zigera kumugambi wo gushimangira ingaruka ziterwa n'ubukonje za PVC film yoroshye.

Muri icyo gihe, dukwiye kandi gusuzuma imbaraga zubushyuhe bwo gutunganya, ubushyuhe bwo gukonjesha, nibindi bintu byo kurwanya ubukonje bwa PVC, hanyuma bihuza nigishushanyo mbonera cyo guhindura mugihe ubushyuhe bwateye cyane.
