Organic silicone softener yakatanga kuma1950s.Uye kukura kwayo kwapfuura nematanho mana.
1.Chizvarwa chekutanga chesilicone softener
Muna 1940, vanhu vakatanga kushandisa dimethyldichlorosilance kuisa pamuvirijirauye akawana imwe mhando yekudzivirira mvura.Muna 1945, Elliott weAmerican General Electric Company (GE) akanyorovesa fiber mune alkaline aqueous solution ine sodium methyl silanol.Mushure mekupisa, fiber yaive yakanaka yekudzivirira mvura.
Mukutanga kwema50s, American Dow Corning Company yakaona kuti machira aibatwa nepolysiloxane neSi-H aive nemaitiro akanaka ekusapinda mvura uye mhepo huru.Asi kunzwa kweruoko kwaive kwakashata uye zvakare iyo silicone firimu yaive yakaoma, brittle uye nyore kudonha.Zvadaro yakashandiswa pamwe chete ne polydimethylsiloxane (PDMS).Ikoko hakuna kungowana yakanaka kusapinda kwemvura maitiro asiwo kupfava ruoko kunzwa.Mushure meizvozvo, kunyangwe zvigadzirwa zvesilicone pasi rese zvakakura nekukurumidza uye zvakafukidza zvakasiyana siyana, zvaive zvemichini misanganiswa ye dimethyl.silicone mafuta, izvo zvaizivikanwa pamwe chete sesilicone mafuta zvigadzirwa.Vakanga vari chizvarwa chekutanga che textile silicone softener.
Chizvarwa chekutanga chesilicone softeners yakananga emulsified silicone mafuta ne mechanical emulsification.Asi nokuti mafuta e-silicone pachayo haana boka rinoshanda, risingagoni kusunga zvakanaka kune jira uye risingashambiki.Saka hazvizoite zvakanaka kana zvichishandiswa chete.
2.Chizvarwa chechipiri chesilicone softener
Kuti akunde kukanganisa kwechizvarwa chekutanga chesilicone softener, vatsvakurudzi vakawana chizvarwa chechipiri chesilicone emulsion ine hydroxyl caps.Iyo yakapfava yainyanya yaisanganisira hydroxyl silicone oiri emulsion uye hydrogen silikoni mafuta emulsion, iyo inogona kuumba network crosslinking chimiro pamucheka wejira pamberi pesimbi inokonzeresa, ichipa machira kupfava kukuru, washability uye kugadzikana.
Asi nekuti yaive nebasa rimwechete uye iri nyore kubviswa uye kunyungudika mafuta, yakatsiviwa nechizvarwa chechitatu chesilicone softener isati yashandiswa zvakanyanya.
3.Chizvarwa chechitatu chesilicone softener
Chizvarwa chechitatu chesilicone softeneryakagadzira inokurumidza pakati payo inoonekwa mumakore achangopfuura.Inosuma zvimwe zvikamu kana mapoka anoshanda mumaketani makuru kana emativi epolysiloxane, seboka repolyether, boka reepoxy, doro rehydroxyl boka, boka reamino, boka recarboxyl, boka re ester, sulfhydryl boka, etc. Inogona kuvandudza zvakanyanya kupfava uye kushanda kwakazara kwe zvikamu zvose zvemicheka.Uyewo kuvimba nemapoka, inogona kupa machira maitiro akasiyana.
Asi kazhinji chizvarwa chechitatu chesilicone softener inofanirwa kusanganiswa ne monofunctional polysiloxane kuti iwane inodiwa kurapa.Zvakaoma kudzora chiyero chekubatanidza, icho chakakonzera zvakanyanya kugadzirwa uye kushandiswa.
4.Chizvarwa chechina chesilicone softener
Chizvarwa chechina chesilicone softener chinowedzera kugadziridzwa chizvarwa chechitatu chesilicone softener maererano nezvinodiwa kupedzisa kwejira.Izvo zvakaunza mamwe mapoka anoshanda, ayo anogona kuzadzisa zvese zvinodiwa zvekugadzira machira pasina kusanganisa.
Micheka inobatwa nemodified silicone softener ine marudzi akasiyana-siyana emapoka anoshingaira ane kuvandudzwa kukuru mukupfava, kushambidzika, elasticity uye hydrophilicity, etc. Inogutsa vashandisi 'marudzi ese ezvido zvemachira, ayo azova nhungamiro huru yekugadzirwa kwesilicone softener pa. present.
