I-Alkyl Polyether: Izinto Ezingasetshenzisiwe Zamakhemikhali Ezinezinhloso Eziningi Zokusetshenziswa Okuhlukahlukene-1
Izinkambu Ezinkulu Zokufaka Isicelo
Embonini yamakhemikhali, ama-alkyl polyether asetshenziswa njengezinto zokusetshenziswa zama-polyurethane foam, ama-adhesive, ama-sealant, nama-elastomer. Ama-polyurethane foam asetshenziswa kabanzi efenisha, omatilasi, izihlalo zezimoto, kanye nezinto zokuvikela izakhiwo. Ama-polyurethane anamathelayo nama-sealant asetshenziswa ekuhlanganiseni izakhiwo, izimoto, kanye namadivayisi kagesi.
Embonini yezemithi, ama-alkyl polyether asebenza njengezinto ezisizayo kanye nezihlanganisi emithini, okuthuthukisa ukuzinza nokuncibilika kwawo. Asetshenziswa futhi ukukhiqiza ama-defoamers, ama-surfactants, kanye nama-wetting agents, asetshenziswa kabanzi ekufakweni ngomlomo, ekhaleni, emaconsini amehlo, emaconsini ezindlebe, kanye nama-shampoo.
Ezimbonini zezindwangu nephepha, ama-alkyl polyether asetshenziswa njengezithambisi, ama-antistatic agents, kanye nama-wetting agents. Athuthukisa ubumnene kanye nezakhiwo zokumelana ne-static zezindwangu futhi athuthukise ikhwalithi yephepha kanye nokusebenza kahle kokukhiqiza ekwenzeni iphepha.
Emikhakheni yemikhiqizo yokuhlanzwa kanye neyokunakekelwa komuntu siqu, ama-alkyl polyether asetshenziswa njengezinto zokuhlanza kanye ne-emulsifier. Abonisa amandla amahle okuhlanza, ukupholisa, ukuqinisa i-foam, ukumanzisa, kanye nokuqinisa i-emulsifier, asetshenziswa kabanzi kuma-shampoo, ekugezeni umzimba, ezihlanzweni zezandla, kanye nasezihlanzweni zokuhlanza izingubo.
Ngaphezu kwalokho, ama-alkyl polyether asetshenziswa njengezinto zokususa ukungcola kanye nezinto zokugcoba embonini kaphethiloli, kanye nezinto zokupholisa kanye nezinto zokugcoba ekucutshungulweni kwensimbi.
Inqubo yokukhiqiza ama-alkyl polyether ngokuvamile ihlanganisa ukwelashwa kwangaphambi kokuqaliswa kwama-initiators nama-catalyst, ukusabela kwe-polymerization okuvula indandatho, kanye nezinyathelo zangemva kokucubungula ezifana nokungaguquki, ukumuncwa, ukuphelelwa amanzi emzimbeni, ukuhlunga, kanye nokuhluzwa.

Ngokufigqiwe
Ngamafuphi, ama-alkyl polyether, njengezinto zokusetshenziswa zamakhemikhali eziningi, adlala indima ebalulekile ezimbonini eziningi. Awagcini nje ngokuthuthukisa ukusebenza komkhiqizo kanye nekhwalithi kodwa futhi asekela intuthuko yemboni yesimanje. Ngokuthuthuka okuqhubekayo kwezobuchwepheshe, amathuba okusetshenziswa kwama-alkyl polyethers azoba maningi nakakhulu.
