N'ihi na nke magburu onwe structural arụmọrụ nke organicmmanụ silicone, a na-etinye ya n'ọtụtụ ebe na textile softening finishing.Ya isi iche bụ: mbụ ọgbọ hydroxyl silicone mmanụ na hydrogen silicone mmanụ, nke abụọ ọgbọ amino silicone mmanụ, ka ọgbọ nke atọ otutu ngọngọ silicone mmanụ.Dị ka ndị mmadụ na-achọ ka aka ka mma, organic mmanụ silicone emewo ọtụtụ iri afọ nke mmezi.
1.Hydroxyl silicone mmanụ
Isi ihe owuwu nke mmanụ silicone hydroxyl bụ polymer linear nwere otu hydroxyl na nsọtụ abụọ yana silicon silicon dị ka agbụ isi.Usoro njikọ a na-ahụkarị bụ nke a na-eme site na hydrolyzing polycondensation nke dimethyl dichlorosilane.N'ihi ike elu ya dị ala, polarity na-adịghị ike na mgbasa ozi na-adịghị ike n'elu ala, ngwa ngwa nke hydroxyl silicone mmanụ na-achọ ịdị arọ molekụla dị elu iji nwee mmetụta dị mma.Ya mere, n'ozuzu hydroxyl silicone mmanụ eji emechaihe nrobụ polymer nwere nnukwu ibu molekụla.E nwere ihe ndọghachi azụ na dị ka mmanụ silicone, n'ihi ike dị ala na mmiri na-adịghị mma nke ukwuu, ọnụ ọgụgụ dị elu nke emulsifiers na igwe na-akpachapụ anya na nke na-achụsasị nke nwere nnukwu mgbasa dị mkpa iji emulsify na-achụsasị ya n'ime microemulsions ka mma.Ma n'agbanyeghị nke a, nkwụsi ike ya ịka nká ka dị njọ.A ka ga-enwe emulsion stratification onu mgbe ogologo oge etinye.
2.Hydrogen silicone mmanụ
Isi ihe owuwu nke mmanụ silicone hydrogen bụ polysiloxane nke nwere njikọ silicon-hydrogen nke ekesara n'akụkụ otu nke agbụ oxygen silicon.Ụzọ njikọ a na-ahụkarị gụnyere hydrolytic polycondensation nke methyl hydrodichlorosilane na polymerization imeghe mgbanaka nke akụkụ mgbanaka hydrosiloxane.N'ihi na nkwụsi ike nke silicon-hydrogen bond adịghị mma, ọ dị mfe ịsacha mmiri na ya mere ọ dị mfe ijikọta polar dị iche iche na ihe textiles.Ya mere, ọ nwere ihe onwunwe adsorptive ka mma.Ọ nwere arụmọrụ ngwa dị mma na eriri cellulose na eriri protein, ebe mmetụta ọjọọ na eriri kemịkal.Dị ka mmanụ silicone hydroxyl, arụmọrụ emulsifying ya adịghị mma yana nkwụsi ike ya adịghị mma.Ọ bụrụ na ọdịnaya hydrogen dị oke elu n'oge a na-etinye ya, ọ dị mfe iduga na ọdịnaya hydrogen nke warara dị oke elu, nke dị ize ndụ na ọnọdụ okpomọkụ dị elu mgbe ị na-edozi.
3.Amino silicone mmanụ
Isi Ọdịdị nkeamino silicone mmanụ isa polysiloxane nwere amino otu n'akụkụ mgbe polymerization site na-agbakwunye amino silane njikọ njikọ.A na-eme ka ịdị nro na nkesa mmiri nke polysiloxane dịkwuo mma n'ihi mma mgbasa ozi na ike njikọ nke amino group na akwa na ezi polarity.Karịsịa na akwa nke cellulose fibers, ọ nwere mmetụta dị mma nke ukwuu.Site n'ịgbanwe uru amonia, ụdị amino silane na-ejikọta ọnụ na ịdị arọ molekul nke mmanụ silikoni nke amino acid nwere ike gbanwee.Nke ahụ nwere ike ịkwadebe mmetụta ngwa bara ụba.Otú ọ dị, n'ihi na isi yinye ya ka bụ siloxane Ọdịdị, ya mere, ọ chọrọ ọzọ emulsifying gị n'ụlọnga iji nweta mma emulsifying mmetụta.N'otu oge ahụ, n'ihi na ọrụ amino nke amino silicone mmanụ dị elu ma ọ dịkwa n'akụkụ ọkpụkpụ.Ya mere, ọ na-esiri ike iwepụ ya na akwa ákwà mgbe adsorption gasịrị.Nke ahụ ga-esi ike iwepụ na ịcha akwa na imecha usoro mgbe ọ dị mkpa ịgbanwe agba, wepụ wrinkles ma ọ bụ ntụpọ silicone.Ọzọkwa iguzogide mmiri siri ike ma ọ bụ alkali mmiri nke emulsion ya ma adịghị ike.
4.Gbochie mmanụ silicone
Isi ihe owuwu nke mgbochi mmanụ silicone bụ na n'ime agbụ polysiloxane bụ isi, etinyere ya, mebere ya na polymerized ya na akụkụ ụfọdụ polyether hydrophilic.Site n'ụzọ nke igbochi, forging na polymerizing na amino yinye akụkụ, nke na-eme ka hydrophilic arụmọrụ na emulsifying onwunwe nke siloxane.Site n'ịgbanwe nha, ụdị na ịdị arọ molekụla nke akụkụ atọ nke yinye, enwere ike ịkwadebe ngwaahịa ndị ọzọ.Maka permeability hydrophilic ya ka mma, ọ dabara adaba maka ịmecha ihe dị nro maka eriri kemịkalụ, yana ịrụ ọrụ ka mma nke ịgbanwe agba na iwepu.N'ihi na otu amino bụ nke amonia, tertiary amonia na ọbụna quaternary amonia, ọ dịghị mfe agba odo.Ọzọkwa ọ bụ ihe nro na-ewu ewu na nyocha mgbanwe n'oge a.
