Te Whakamahinga o ia ra matū o ia ra Hydroxypropyl Methyl Cellulose (HPMC) ki te horoi

Ko te hydroxypropyl methylcellulose matū o ia ra he polymer waihanga i hangaia mai i te cellulose taiao ma te whakarereketanga matū. Ko te cellulose ether he hua o te cellulose taiao. He rereke te hanga o te cellulose ether i nga polymers waihanga. Ko te mea tino taketake ko te cellulose, he pūhui polymer māori. Na te mea motuhake o te hanganga cellulose maori, karekau he kaha o te cellulose ki te tauhohe me nga kaihoko whakaea. Heoi, i muri i te maimoatanga o te kaipupuhi pupuhi, ka pakaru nga hononga hauwai kaha i waenga i nga mekameka ngota me nga mekameka, a, ko te tukunga kaha o te roopu hydroxyl ka waiho hei cellulose alkali. Tikina te cellulose ether.

200,000 pokey hydroxypropyl methylcellulose inamata mo ia ra matū matū he paura ma, paku kowhai ranei, he kakara, he reka me te kore paitini. Ka taea te rewa i roto i te wai matao me te whakarewa whakauru o te mea waro hei hanga i tetahi otinga poikeri marama. Ko te wai o te wai he mahi mata, he tino marama, he kaha te pumau, a kaore e pa ki te pH ina rewa ki te wai. He whakamaaru me te whakatio i roto i nga shampoos me nga wai kaukau, he pupuri wai me nga taonga hanga kiriata pai mo te makawe me te kiri. Na te kaha o te pikinga o nga rawa taketake, ko te whakamahi i te cellulose (antifreeze thickener) i roto i te shampoo me te wai horoi ka taea te whakaiti i te utu me te whakatutuki i te painga e hiahiatia ana.

Nga waahanga me nga painga o te HPMC matū matū o ia ra:

1. He iti te riri, te wera nui me te kore-paitini;

2. Te uara pH whanui, ka taea te whakarite i tona pumau i roto i te awhe o te uara pH 3-11;

3. Whakanuia te whakamaarama;

4. Whakanuia te pahuka, whakapumau i te pahuka, whakapai ake te ahua o te kiri;

5. Te whakapai ake i te rere o te punaha.

Ko te whānuitanga o te tono o ia ra matū cellulose HPMC:

Ka whakamahia i roto i te shampoo, te horoi tinana, te horoi kanohi, te hinu, te kirīmi, te kiri, te toner, te whakamaarama makawe, nga hua whakapaipai, te toothpaste, te huware, te wai mirumiru takaro.

Ko te mahi o ia ra matū cellulose HPMC

I roto i nga tono whakapaipai, ka whakamahia te nuinga mo te matotoru, te hukahuka, te emulsification pumau, te whakamararatanga, te adhesion, te whakapai ake i te hanga kiriata me nga taonga pupuri wai o nga mea whakapaipai, ka whakamahia nga hua-nui mo te matotoru, ko nga hua iti-viscosity te nuinga e whakamahia ana mo te aukati. marara me te hanga kiriata

Hangarau HPMC o ia ra matū matū cellulose:

Ko te viscosity o te hydroxypropyl methylcellulose e tika ana mo te ahumahi matū o ia ra ko te nuinga o te 100,000, 150,000, me te 200,000. E ai ki taau ake tikanga, ko te nui o te taapiri i roto i te hua ko te tikanga 3 ki te 5/1000
