Ema Polyols: Tintfo Letiluhlata Letinetinhloso Letinyenti Tekusebentisa Timboni Nebatsengisi
Tindzawo Letinkhulu Tesicelo
Embonini yemakhemikhali, ema polyols tintfo letibalulekile letiluhlata tekukhicita tintfo letinesisindvo lesiphakeme se molecule letifana nema polyester, ema polyethers, kanye nema polyurethanes. Sibonelo, i-ethylene glycol isetjentiswa kukhicita i-polyethylene terephthalate (i-PET), lesetjentiswa kakhulu emabhodleleni epulasitiki kanye nemicu. I-Polyethylene glycol (PEG) isetjentiswa kukhicita tintfo letehlukene letisebenta etulu kanye nekugcobisa. Ngekwengeta, ema polyols angasebenta njengetinhlayiya tekuncibilikisa tinhlobonhlobo tetintfo letiphilako, kwenta ncono kusebenta kahle kwekuphendvula.
Embonini yemitsi, ema polyols asetjentiswa kakhulu njengetinhlayiya, emapulasitiki, kanye nemanti. Sibonelo, ipropylene glycol ne glycerol kuvame kusetjentiswa ekulungiseleleni imijovo, tintfo letimanti temlomo, kanye nemafutsa kwenta ncono kuncibilika kwetidzakamiva kanye nekusimama. Ngekwengeta, ema polyols angasetjentiswa kukhicita emafomula etidzakamiva letilawulwako, kulawula lizinga lekukhishwa kwetidzakamiva.
Embonini yekudla, ema polyols asetjentiswa njengetintfo letinongotelako, tintfo letimantisako, kanye netintfo letihlanganisako. Sibonelo, iglycerol ne polyethylene glycol ingasetjentiswa ekukhiciteni tintfo letinongotelako, tintfo letibhakiwe, kanye netinatfo, kuniketa bumnandzi kanye nekugcina umswakama. Ngekwengeta, ema polyols angasetjentiswa kulungisa kucina kanye nekutiva kwemlomo wekudla, kwelula imphilo yayo yeshelufu.
Embonini yetimonyo kanye nekunakekela sikhumba, ema polyols asetjentiswa kakhulu njengetintfo letimantisako kanye netintfo letihlanganisako. Sibonelo, ipropylene glycol ne glycerol ingamunya umswakama, igcine sikhumba netinwele tinemanti. Ngekwengeta, ema polyols angasetjentiswa ekukhiciteni tintfo tekuvikela lilanga, emashampu, kanye netindlela tekugcobisa, kuniketa imiphumela yekumantisa kanye nekugcobisa.
Embonini yemapulasitiki, ema polyols asetjentiswa njengemapulasitiki kwentela kukhulisa kugucugucuka kanye nekucubungula emapulasitiki. Sibonelo, i-glycerol ne-polyethylene glycol ingasetjentiswa njengemapulasitiki e-polyvinyl chloride (i-PVC), kwenta ncono kugucugucuka kwayo kanye nekucina kwayo. Ngekwengeta, ema polyols angasetjentiswa kukhicita emapulasitiki labolako, kunciphisa umtselela wemvelo.
Embonini yekugcobisa kanye netinki, ema polyols asetjentiswa njengetinhlanganisela kanye netihlanganisi. Tingancibilikisa tinhlobonhlobo tema resin kanye ne pigments, kuniketa tintfo letinhle tekwakha emafilimu. Sibonelo, iPolyethylene glycol ingasetjentiswa kukhicita tintfo letifakwe emanti kanye netinki, kuniketa tisombululo letilungele imvelo futsi letisebenta kahle.

Ngalokufishane
Ngalokufishane, ema polyols, njengetintfo letibalulekile temakhemikhali laphilako, adlala indzima lebalulekile etimbonini letiningi. Abagcini nje ngekutfutfukisa kusebenta kwemkhicito kanye nelizinga kepha baphindze basekele kutfutfukiswa kwemboni yesimanje. Ngekuchubeka kwebuchwepheshe, ematfuba esicelo ema polyols atawuba banti kakhulu.
