Nekuda kwekuita kwakanakisa kwemaitiro e organicsilicone mafuta, inoshandiswa zvakanyanya mumucheka wekunyorovesa kupedzisa.Mhando dzayo huru ndeidzi: chizvarwa chekutanga hydroxyl silicone oiri uye hydrogen silicone oiri, yechipiri chizvarwa amino silicone mafuta, kune yechitatu chizvarwa akawanda block silicone oiri.Sezvo kudiwa kwevanhu kwekubata kwave nani, organic silicone oiri yave makumi emakore ekuvandudzwa.
1.Hydroxyl silicone mafuta
Iyo huru chimiro che hydroxyl silicone oiri ndeye linear polymer ine hydroxyl mapoka kumativi ese uye silica silicon seyetani huru.Iyo yakajairika synthesis nzira ndeye kugadzirwa ne hydrolyzing polycondensation ye dimethyl dichlorosilane.Nekuda kwesimba rayo repasi pasi, isina simba polarity uye isina kusimba adsorption pane substrate pamusoro, iyo yakajairwa kushandiswa kwehydroxyl silicone oiri inoda huremu hwemamorekuru kuti uve nekuita kwakanaka kwekushandisa.Naizvozvo, kazhinji iyo hydroxyl silicone oiri inoshandiswa sekupedzisasofteneripolymer ine huremu hwepamusoro-soro.Panouya chidzoro chekuti semafuta esilicone, nekuda kwekuderera kwesimba repamusoro uye kusanyanya kushata kwemvura, chikamu chepamusoro che emulsifiers uye muchina wekugera uye wekuparadzira une kupararira kwepamusoro unodiwa kuti uise emulsify nekuiparadzira kuita ma microemulsions ari nani.Asi pasinei neizvi, kugadzikana kwayo kwekuchembera kuchiri kwakashata.Pachave paine emulsion stratification phenomenon mushure menguva yakareba yakaiswa.
2.Hydrogen silicone mafuta
Chimiro chikuru chehydrogen silicone oiri ndeye polysiloxane ine silicon-hydrogen bond yakagoverwa zvakaenzana padivi reboka resilicon oxygen cheni.Idzo dzakajairika nzira dzekugadzira dzinosanganisira hydrolytic polycondensation yemethyl hydrodichlorosilane uye mhete-inovhura polymerization yehydrosiloxane mhete miviri.Nekuti kugadzikana kwesilicon-hydrogen bond haina kunaka, zviri nyore kuita dehydrogenate uye saka zviri nyore kushambadza nemapoka epolar pane machira.Saka ine zvirinani adsorptive pfuma.Iyo ine yakanaka application performance pane cellulose fiber uye mapuroteni faibha, nepo yakaipa mhedzisiro pamakemikari fiber.Zvakafanana nehydroxyl silicone oiri, kuita kwayo emulsifying hakuna kunaka uye kugadzikana kwayo kwakashata.Kana iyo hydrogen yemukati yakanyanya kukwirisa panguva yekushandisa, zviri nyore kutungamira kune iyo mitsetse yehydrogen yemukati yakawandisa, iyo ine njodzi kune yakanyanya tembiricha nharaunda painogadzika.
3.Amino silicone mafuta
Chimiro chikuru cheamino silicone mafuta isa polysiloxane ine amino boka pamativi mushure me polymerization nekuwedzera amino silane coupling agent.Kupfava uye kupararira kwemvura kwepolysiloxane kwakagadziridzwa zvakanyanya nekuda kweiyo yakanaka adsorption uye kugona kusunga kweboka reamino kumucheka uye yakanaka polarity.Kunyanya pamachira e cellulose fibers, ine yakanyanya kunaka application maitiro.Nekugadzirisa kukosha kweammonia, rudzi rweamino silane coupling agent uye molecular weight yeamino silicone oiri inogona kugadziriswa.Izvo zvinogona kugadzirira hupfumi hwekushandisa mhedzisiro.Nekudaro, nekuti cheni yayo huru ichiri siloxane chimiro, saka inoda yakawanda emulsifying mumiriri kuti iwane zvirinani emulsifying mhedzisiro.Panguva imwecheteyo, nekuti iyo amino chiitiko cheamino silicone oiri yakakwira uye zvakare iri padivi bhonzo.Saka zvakaoma kuibvisa kubva mumucheka mushure mekudsorption.Izvo zvichave zvakaoma kubvisa mumucheka wekudhaya uye kupedzisa maitiro kana ichida kugadzirisa ruvara, kubvisa wrinkles kana silicone mavara.Uyewo kurwisana nemvura yakaoma kana alkali mvura ye emulsion yayo zvose hazvina simba.
4.Bvisa silicone mafuta
Chimiro chikuru che block silicone oiri ndechekuti mucheni huru yepolysiloxane yakamisikidzwa, yakaumbwa uye yakashongedzwa nemhando ye hydrophilic polyether cheni zvikamu.Nenzira yekuvhara, kuumba uye polymerizing neamino chain segment, iyo inovandudza hydrophilic kuita uye emulsifying pfuma ye siloxane.Nekugadzirisa reshiyo, mhando uye huremu hwemamorekuru ezvikamu zvitatu zveketani, panogona kugadzirira zvimwe zvigadzirwa.Nokuda kwayo zviri nani hydrophilic permeability, inonyanya kukodzera kunyorovesa kupedzisa kwemakemikari fibers, nekushanda kuri nani kwekugadzirisa ruvara uye kubvisa.Nekuti boka remamino ndere ammonia, tertiary ammonia uye kunyange quaternary ammonia, hazvisi nyore kuita yero.Zvakare inopfavisa yakakurumbira mukugadziridza tsvagiridzo mazuva ano.
