I-organic silicone softener yaqala ngeminyaka yawo-1950s.Futhi ukukhula kwawo sekudlule izigaba ezine.
1.Isizukulwane sokuqala se-silicone softener
Ngo-1940, abantu baqala ukusebenzisa i-dimethyldichlorosilance ukuze bakhulelweindwangufuthi yazuza uhlobo oluthile lomphumela wokuvimbela amanzi.Ngo-1945, u-Elliott we-American General Electric Company (GE) wacwilisa imicu esixazululweni se-alkaline samanzi nge-sodium methyl silanol.Ngemuva kokushisa, i-fiber yayinomphumela omuhle wokungangeni kwamanzi.
Ngasekuqaleni kweminyaka yama-50s, i-American Dow Corning Company yathola ukuthi izindwangu eziphathwe i-polysiloxane nge-Si-H zazinomphumela omuhle ongangeni manzi kanye nokungena komoya okuhle.Kodwa umuzwa wesandla wawungemuhle futhi nefilimu ye-silicone yayiqinile, inhlakanhlaka futhi kulula ukuwa.Yabe isisetshenziswa kanye ne-polydimethylsiloxane (PDMS).Kukhona hhayi kuphela etholwe umphumela omuhle manzi kodwa futhi isandla esithambile umuzwa.Ngemuva kwalokho, nakuba imikhiqizo ye-silicone emhlabeni wonke yathuthuka ngokushesha futhi yahlanganisa izinhlobo eziningi, ngokuyisisekelo yayiyingxenye yezingxube zemishini ye-dimethyl.amafutha abicah, ezaziwa ngokuhlanganyela ngokuthi imikhiqizo kawoyela we-silicone.Babeyisizukulwane sokuqala se-textile silicone softener.
Isizukulwane sokuqala se-silicone softeners ngqo emulsified abicah uwoyela by emulsification mechanical.Kodwa ngenxa yokuthi uwoyela we-silicone ngokwawo awunalo iqembu elisebenzayo, elingakwazi ukubopha kahle kwendwangu futhi alikwazi ukuwasha.Ngakho-ke ngeke kuzuze umphumela omuhle uma isetshenziswa yodwa.
2.Isizukulwane sesibili se-silicone softener
Ukuze banqobe ukushiyeka kwesizukulwane sokuqala se-silicone softener, abacwaningi bathole isizukulwane sesibili se-silicone emulsion enamakepisi e-hydroxyl.I-softener ngokuyinhloko yayihlanganisa i-emulsion kawoyela ye-hydroxyl abicah kanye ne-hydrogen silicone emulsion yamafutha, engakha isakhiwo se-crosslinking yenethiwekhi ebusweni bendwangu phambi kwe-catalyst yensimbi, idlulisela izindwangu ukuthamba okukhulu, ukuqina nokuqina.
Kodwa ngenxa yokuthi yayinomsebenzi owodwa futhi amafutha ancibilika kalula futhi antanta, yathathelwa indawo isizukulwane sesithathu sesithambiso se-silicone ngaphambi kokuba sisetshenziswe kabanzi.
3.Isizukulwane sesithathu se-silicone softener
Isizukulwane sesithathu sei-silicone softeneriye yathuthuka esheshayo phakathi kwayo evela eminyakeni yamuva.Yethula ezinye izingxenye noma amaqembu asebenzayo emaketangeni amakhulu noma aseceleni e-polysiloxane, njengeqembu le-polyether, iqembu le-epoxy, iqembu le-alcohol hydroxyl, iqembu le-amino, iqembu le-carboxyl, iqembu le-ester, iqembu le-sulfhydryl, njll. Ingathuthukisa kakhulu ukuthamba nokusebenza okuphelele kwe zonke izici zezindwangu.Futhi ukuthembela emaqenjini, kunganikeza izindwangu isitayela esihlukile.
Kodwa ngokuvamile isizukulwane sesithathu sesithambile se-silicone kufanele sihlanganiswe ne-monofunctional polysiloxane ukuze sizuze umphumela odingekayo wokwelapha.Kunzima ukulawula izinga lokuhlanganisa, elibe nomthelela omkhulu ekukhiqizeni nasekusetshenzisweni.
4.Isizukulwane sesine se-silicone softener
Isizukulwane sesine se-silicone softener siphinde salungiswa isizukulwane sesithathu sesithambile se-silicone ngokuya ngomphumela odingekayo wokuqeda wendwangu.Lokho kwethule amaqembu asebenzayo, angahlangabezana nazo zonke izidingo zokucubungula zendwangu ngaphandle kokuhlanganisa.
Izindwangu ezilashwe ngesithambisi se-silicone esilungisiwe ngezinhlobo ezahlukene zamaqembu asebenzayo zinokuthuthuka okukhulu ekuthambeni, ukushaqeka, ukunwebeka kanye ne-hydrophilicity, njll. Yenelisa zonke izinhlobo zezidingo zabasebenzisi ezindwangu, eseziphenduke inkomba eyinhloko yokuthuthukiswa kwesithambile se-silicone samanje.
