IiPolyols: Izinto ezisetyenziswa kwiinjongo ezininzi kwizicelo zemizi-mveliso kunye nabathengi
IiNdawo eziPhambili zeSicelo
Kwishishini leekhemikhali, ii-polyols zizinto eziphambili zokwenza izinto ezinobunzima obukhulu beemolekyuli ezifana nee-polyester, ii-polyethers, kunye nee-polyurethanes. Umzekelo, i-ethylene glycol isetyenziselwa ukuvelisa i-polyethylene terephthalate (PET), esetyenziswa kakhulu kwiibhotile zeplastiki kunye neefayibha. I-Polyethylene glycol (PEG) isetyenziselwa ukuvelisa ii-surfactants ezahlukeneyo kunye nee-lubricants. Ukongeza, ii-polyols zinokusebenza njenge-solvents zokunyibilikisa iintlobo ngeentlobo zeekhompawundi ze-organic, ziphucula ukusebenza kakuhle kwempendulo.
Kwishishini lamayeza, ii-polyols zisetyenziswa kakhulu njengezinyibilikisi, iiplastiki, kunye ne-humectants. Umzekelo, i-propylene glycol kunye ne-glycerol zihlala zisetyenziswa ekulungiseleleni iinaliti, ulwelo oluselwelweni, kunye namafutha okugcoba ukuphucula ukunyibilika kwamayeza kunye nokuzinza. Ukongeza, ii-polyols zingasetyenziselwa ukuvelisa iifomyula zamayeza ezikhutshwayo ezilawulwayo, ezilawula izinga lokukhululwa kwamayeza.
Kwishishini lokutya, ii-polyols zisetyenziswa njengezinto ezibangela iincasa, izinto ezibangela ii-humectants, kunye nezixutyisi. Umzekelo, i-glycerol kunye ne-polyethylene glycol zingasetyenziswa ekuveliseni ii-confectionery, izinto ezibhakiweyo, kunye neziselo, zibonelela ngobumnandi kunye nokugcinwa komswakama. Ukongeza, ii-polyols zingasetyenziselwa ukulungisa ubume kunye nokuziva komlomo kokutya, kwandise ubomi bako eshelufini.
Kwishishini lezinto zokuthambisa nokhathalelo lolusu, ii-polyols zisetyenziswa kakhulu njengee-humectants kunye nee-emulsifiers. Umzekelo, i-propylene glycol kunye ne-glycerol zinokufunxa umswakama, zigcine ulusu kunye neenwele zimanzi. Ukongeza, ii-polyols zingasetyenziswa ekuveliseni ii-sunscreens, ii-shampoos, kunye ne-conditioners, zibonelela ngemiphumo yokufumisa kunye nokuthambisa.
Kwishishini leeplastiki, iipolyols zisetyenziswa njengeeplastiki ukuphucula ukuguquguquka kunye nokuqhubekeka kweeplastiki. Umzekelo, iglycerol kunye ne-polyethylene glycol zingasetyenziswa njengeeplastiki ze-polyvinyl chloride (PVC), nto leyo ephucula ukuguquguquka kwayo kunye nokuqina kwayo. Ukongeza, iipolyols zingasetyenziselwa ukuvelisa iiplastiki ezinokubola, nto leyo enciphisa impembelelo yokusingqongileyo.
Kwishishini leengubo kunye nee-inki, ii-polyols zisetyenziswa njengezinyibilikisi kunye nee-emulsifiers. Zinokunyibilikisa iintlobo ngeentlobo zee-resins kunye nee-pigment, zibonelela ngeempawu ezilungileyo zokwenza ifilimu. Umzekelo, i-polyethylene glycol ingasetyenziselwa ukuvelisa iingubo kunye nee-inki ezisekelwe emanzini, zibonelela ngezisombululo ezinobuhlobo nokusingqongileyo nezisebenzayo.

Isishwankathelo
Ngamafutshane, ii-polyols, njengezinto ezibalulekileyo ze-organic chemical raw materials, zidlala indima ebalulekileyo kumashishini amaninzi. Aziphuculi nje kuphela ukusebenza kwemveliso kunye nomgangatho kodwa zikwaxhasa uphuhliso lweshishini lanamhlanje. Ngokuqhubela phambili kwezobuchwepheshe, amathuba okusetyenziswa kwee-polyols aya kuba banzi nangakumbi.
