Ngenxa yokusebenza okuhle kakhulu kwesakhiwo se-organicamafutha abicah, isetshenziswa kabanzi ekuqedeni ukuthambisa izindwangu.Izinhlobo zayo eziyinhloko yilezi: isizukulwane sokuqala i-hydroxyl silicone oil kanye ne-hydrogen silicone oil, isizukulwane sesibili sikawoyela we-amino silicone, kuya esizukulwaneni sesithathu uwoyela we-multiple block silicone.Njengoba isidingo sabantu sokubamba sesithuthukile, uwoyela we-organic silicone usethuthuke amashumi eminyaka.
1.Amafutha e-silicone e-Hydroxyl
Isakhiwo esiyinhloko samafutha e-silicone e-hydroxyl iyi-polymer eqondile enamaqembu e-hydroxyl emikhawulweni yomibili kanye ne-silica silicon njengeketango eliyinhloko.Indlela evamile yokuhlanganisa yileyo eyenziwa yi-hydrolyzing polycondensation ye-dimethyl dichlorosilane.Ngenxa yamandla ayo aphansi angaphezulu, i-polarity ebuthakathaka kanye nokukhangisa okubuthakathaka endaweni engaphansi kwe-substrate, ukusetshenziswa okuvamile kwamafutha e-silicone e-hydroxyl kudinga isisindo esiphezulu samangqamuzana ukuze kube nomphumela omuhle wokufaka isicelo.Ngakho-ke, ngokuvamile uwoyela we-silicone we-hydroxyl osetshenziswa njengokuqedaokothambisai-polymer enesisindo samangqamuzana aphezulu.Kuvela i-drawback yokuthi njengamafutha e-silicone, ngenxa yamandla aphansi angaphezulu kanye nokuhlakazeka kwamanzi okubi kakhulu, ingxenye ephezulu yama-emulsifiers kanye nomshini wokugunda nokusabalalisa onokusabalalisa okuphezulu kuyadingeka ukuze kufakwe emulsify futhi kuhlakazwe kuma-microemulsions angcono.Kodwa naphezu kwalokhu, ukuzinza kwayo kokuguga kusekubi.Kusazoba khona i-emulsion stratification phenomenon ngemuva kokubekwa isikhathi eside.
2.Amafutha e-silicone ye-hydrogen
Isakhiwo esiyinhloko samafutha e-hydrogen silicone i-polysiloxane ene-silicon-hydrogen bond esatshalaliswa ngokulinganayo eqenjini elihlangothini leketango le-silicon oxygen.Izindlela zokuhlanganisa ezijwayelekile zifaka i-hydrolytic polycondensation ye-methyl hydrodichlorosilane kanye ne-polymerization evula indandatho yemizimba yendandatho ye-hydrosiloxane.Ngenxa yokuthi ukuzinza kwe-silicon-hydrogen bond akulungile, kulula ukuyikhipha futhi kulula ukuyikhangisa ngamaqembu amhlophe ezintweni zendwangu.Ngakho inempahla ye-adsorptive engcono.Inokusebenza okuhle kokusebenza kumafayibha e-cellulose nama-protein fibers, kuyilapho inomthelela omubi kumafayibha amakhemikhali.Ngokufanayo namafutha e-silicone e-hydroxyl, ukusebenza kwawo kwe-emulsifying akukuhle futhi ukuzinza kwawo akulungile.Uma okuqukethwe kwe-hydrogen kuphezulu kakhulu ngesikhathi sokusetshenziswa, kulula ukuholela ekutheni okuqukethwe kwe-hydrogen enemigqa kuphezulu kakhulu, okuyingozi endaweni yokushisa ephezulu lapho kusetha.
3.Amafutha abicah amino
Isakhiwo esikhulu seamafutha abicah amino ii-sa polysiloxane equkethe iqembu le-amino ezinhlangothini ngemva kokwenziwa kwe-polymerization ngokungeza i-amino silane ehlanganisa i-ejenti.Ukuthamba nokuhlakazeka kwamanzi kwe-polysiloxane kuba ngcono kakhulu ngenxa ye-adsorption enhle nekhono lokubopha leqembu le-amino endwangu kanye ne-polarity enhle.Ikakhulukazi ezindwangu zemicu ye-cellulose, inomphumela omuhle kakhulu wokufaka isicelo.Ngokulungisa inani le-ammonia, uhlobo lwe-amino silane coupling agent kanye nesisindo samangqamuzana sawoyela we-amino silicone singalungiswa.Lokho kungalungiselela imiphumela ecebile yohlelo lokusebenza.Kodwa-ke, ngenxa yokuthi iketango layo eliyinhloko liseyisakhiwo se-siloxane, ngakho-ke idinga i-emulsifying eningi ukuze kuzuzwe umphumela ongcono we-emulsifying.Ngesikhathi esifanayo, ngoba umsebenzi we-amino kawoyela we-amino silicone uphakeme futhi usethanjeni elihlangothini.Ngakho-ke kunzima ukuyikhipha kwendwangu ngemva kwe-adsorption.Lokho kuzoba nzima ukususa ku-textile dyeing kanye nenqubo yokuqeda lapho idinga ukuguqula umbala, ukuqeda imibimbi noma amabala a-silicone.Futhi ukumelana namanzi aqinile noma amanzi e-alkali emulsion yawo kokubili kubuthakathaka.
4.Vimba uwoyela we-silicone
Isakhiwo esiyinhloko samafutha we-block silicone yukuthi ochungechungeni oluyinhloko lwe-polysiloxane lushumekiwe, lufakwe futhi lwenziwe i-polymerized ngezingxenye zeketanga le-hydrophilic polyether.Ngendlela yokuvimbela, ukubumba kanye ne-polymerizing nge-amino chain segment, ethuthukisa ukusebenza kwe-hydrophilic kanye nempahla emulsifying ye-siloxane.Ngokulungisa isilinganiso, izinhlobo kanye nesisindo samangqamuzana ezingxenye ezintathu zamaketanga, kungalungiselela imikhiqizo eminingi.Ngokufinyelela kwayo okungcono kwe-hydrophilic, ifaneleka kakhulu ekuqedeni ukuthambisa imicu yamakhemikhali, ngokusebenza kangcono kokuguqula umbala nokukhipha.Ngenxa yokuthi iqembu le-amino lingele-ammonia, i-tertiary ammonia kanye ne-quaternary ammonia, akulula ukuphuzi.Futhi iyisithambisi esidumile ocwaningweni lokuguqulwa kulezi zinsuku.
