Ko te hydroxypropyl methyl cellulose matū ia ra he polymer waihanga i mahia ma te whakarereketanga matū o te cellulose taiao hei rauemi mata. Ko te cellulose ether he huanga o te cellulose maori, he rereke te hanga cellulose ether me te polymer synthetic, ko te mea tino taketake he cellulose, he pūhui polymer taiao. Na te mea motuhake o te hanganga cellulose maori, karekau he kaha o te cellulose ki te tauhohe me nga apiha whakaetere. Heoi ano, i muri i te maimoatanga o te kai pupuhi, ka ngaro nga here hauwai kaha i waenga, i roto hoki i nga mekameka ngota, ka tukuna te ngohe o te roopu hydroxyl ki te cellulose alkali me te kaha tauhohenga. Whai muri i te tauhohenga o te kaihoko whakaetere, ka huri te roopu -OH ki te roopu -OR ki te whiwhi etera cellulose.
Ia ra matū kōeke motuhake 200 mano pokey tonu hydroxypropyl methyl cellulose ko te paura ma, paku kōwhai ranei, me te kakara, reka, kore-paitini. Wairewa i roto i te ranunga o te wai matao me te wairewa waro ki te hanga i te wairewa viscous marama. Ko te wairewa wai he mahi mata, he tino marama, he kaha te pumau, ko te wairewa i roto i te wai kaore e pa ki te pH. Ko te whakamarumaru me te paahitanga antifreeze i roto i te shampoo me te horoi tinana, te pupuri wai me te hanga kiriata pai mo nga makawe me te kiri. Na te nui o te pikinga o nga rauemi mata, ka taea te whakamahi i te cellulose (antifreeze thickener) ki te shampoo me te horoi tinana ka taea te whakaiti i te utu me te whakatutuki i nga hua e hiahiatia ana.
1. Ko nga ahuatanga me nga painga o te HPMC matū o ia ra.
1, iti irritation, teitei pāmahana me te takoto;
2, te whānuitanga o te pH pumau, i roto i te uara pH o te awhe 3-11 ka taea te whakarite i tona pumau;
3. Te whakanui ake i te aro o te whakaaro;
4. Whakanuia te mirumiru, whakapumau i te mirumiru, whakapai ake te ahua kiri;
5. He pai te whakapai ake i te moni o te punaha.
2 ia ra matū kōeke cellulose hōkai tono HPMC:
Ka whakamahia i roto i te shampoo, te horoi tinana, te horoi kanohi, te miraka, te kirīmi, te kiri, te toner, te whakamahana, nga hua hanga, te toothpaste, te wai, te wai mirumiru takaro.
3 Ko te mahi a te HPMC matū o ia ra te karaehe cellulose:
I roto i te whakamahinga o nga mea whakapaipai, ka whakamahia te nuinga mo te matotoru, te hukahuka, te emulsification pumau, te whakamararatanga, te adhesion, te hanga kiriata me te whakapai ake i te mahi pupuri wai, ka whakamahia nga hua viscosity hei matotoru, nga hua pokey iti e whakamahia ana hei whakamararatanga whakatārewatanga me te hanga kiriata. .
4 ia ra matū kōeke cellulose hangarau HPMC:
Hydroxypropyl methyl muka ki te urutau ki te pokey o te ahumahi matū ko te nuinga 100 mano, 150 mano, 200 mano, kia rite ki to ratou ake tātai ki te whiriwhiri i te nui o te tāpiri i roto i te hua ko te tikanga e toru ki te rima mano.
