Ma Polyols: Zibelesyo Zibelesyegwa Mumakkampani Aakubelesya Mumakwebo
Zibeela Zipati Zyakubelesya
Mumakwebo aamakemikalu, ma polyol nzintu zipati zibelesyegwa mukupanga zintu zilema kapati mbuli ma polyesters, ma polyethers, antoomwe ama polyurethanes. Mbuli chitondeezyo, ethylene glycol ilabelesyegwa kupanga polyethylene terephthalate (PET), iibelesyegwa kapati mumabbodela aamapulasitiki amuma fiber. Polyethylene glycol (PEG) ibelesyegwa kupanga zintu zisiyene-siyene zya surfactant a lubricants. Kuyungizya waawo, ma polyols alakonzya kubeleka mbuli zintu zikonzya kunyonyoona zintu zisiyene-siyene, ikusumpula kuchita obotu.
Mumakwebo aamisamu, ma polyols alabelesyegwa kapati mbuli zintu zipa kuti zintu zibe kabotu, zintu zipa kuti kube pulasitiki, alimwi azintu zipa kuti kube buteteete. Mbuli chitondeezyo, propylene glycol a glycerol zilabelesyegwa kapati mukubamba misamu, maanzi aamukanwa, amafuta kuti misamu inyonyooke akukkalwa moyo. Kuyungizya waawo, ma polyols alakonzya kubelesegwa kupanga misamu iikonzya kuzwa, kweendelezya mweelwe wa misamu iizwa.
Mumakwebo aazyakulya, ma polyols abelesyegwa mbuli zintu zitontola, zitontola, antoomwe azintu zipa kuti zintu zifwefwemale. Mbuli chitondeezyo, glycerol antoomwe a polyethylene glycol zilakonzya kubelesegwa mukupanga zintu zyakunywa, zyakulya zyakujika, azyakunywa, kupa kuti kube bubotu akujatisya maanzi. Kuyungizya waawo, ma polyols alakonzya kubelesegwa kuchincha bube bwachakulya, akupa kuti chakulya chikkale chilamfu.
Mumakwebo aakulisakatizya akubamba chikumba, ma polyols alabelesyegwa loko mbuli zintu zipa kuti chikumba chifwefwemale. Mbuli chitondeezyo, propylene glycol a glycerol zilakonzya kunyona maanzi, akupa kuti chikumba amasusu kazijisi maanzi. Kuyungizya waawo, ma polyols alakonzya kubelesegwa mukupanga mafuta aakwabilila zuba, ma shampoo, ama conditioner, kupa kuti kube kuteteeta akusanzya.
Mumakwebo aamapulasitiki, ma polyols abelesyegwa mbuli zintu zipa kuti mapulasitiki ayungizye kuchincha akubelesegwa kwamapulasitiki. Mbuli chitondeezyo, glycerol a polyethylene glycol zilakonzya kubelesegwa mbuli zintu zipa kuti polyvinyl chloride (PVC) ibe aapulasitiki, ikusumpula kuchincha kwayo akuyuma kwayo. Kuyungizya waawo, ma polyols alakonzya kubelesegwa kupanga mapulasitiki aakonzya kubola, akugwisya ntenda kubusena.
Mumulimo wakuvwumba ama ingi, ma polyols abelesyegwa mbuli zintu zipa kuti zintu zibe kabotu. Zilakonzya kunyonyoona ma resini aasiyene-siyene, kupa bube bwakupanga filimu. Mbuli chitondeezyo, polyethylene glycol ilakonzya kubelesegwa kupanga zintu zyakuvwumba ama ingi, kupa nzila zitanyonganyi busena.

Mubufwaafwi
Muchi chifwiifwi, ma polyols, mbuli zintu ziyandikana zyakubelesya misamu iikola, alabeleka mulimo mupati mumakwebo miingi. Tazisumpuli buyo kubeleka kabotu kwazintu pele alimwi zigwasyilizya kuyaambele kwamakwebo aamazubaano. Kakuli kuyaambele kwabusongo, nzila zyakubelesya ma polyols ziyooba zipati.
