Focus on Cellulose ethers

He aha te maapono whakahiatotanga o te hydroxypropyl methylcellulose?

Ka whakamahia te Hydroxypropyl methylcellulose hei taputapu mata hei whakaputa hinu, ka taea te mohio ki te whakamahi o te huka katoa, te whakapai ake i te tere o te whakamahi i nga rauemi mata, te whakaiti i te toenga o te taputapu i roto i te hupa fermentation, me te whakaiti i te utu mo te maimoatanga waipara. Ko tenei hydroxypropyl methylcellulose Ko te ahuatanga matua he pai ki te arotautanga o te puranga, te whangai-puranga me nga tukanga FERMENTATION tonu, te karo i te raupapa o nga raruraru penei i te whakahaere o te hanganga reo me te reiti waimeha; he pai hoki ki te whakahaere i te tukanga FERMENTATION.

Hydroxypropyl methylcellulose, te mea raw cellulose, ka taea te para hei miro, te penupenu rakau ranei. He mea tino tika ki te kuru i mua i te whakamaaramatanga, i te wa ranei o te whakamaaramatanga. Ko te kuru ko te whakangaro i te cellulose raw rauemi ma te hiko miihini. Ko te hanganga ahua whakahiato o nga macromolecules cellulose ka taea te whakaiti i te tohu o te tioata me te polymerization, te whakanui ake i te waahi o te mata, na reira ka pai ake te whakauru me te kaha o te tauhohenga matū o te reagent tauhohenga ki nga roopu hydroxyl e toru i runga i te roopu mowhiti huka o te macromolecule cellulose.

Ahakoa ko te maataapono whakahiato o te whakamaaramatanga o te hydroxypropyl methylcellulose kaore i te uaua, ko nga momo taiao o te whakamaaramatanga, te kuru o nga rauemi mata, te whakamaarama, te whakaora whakarewa, te wehenga centrifugal, te horoi me te whakamaroke ka uru ki te maha o nga hangarau matua me nga tohu matauranga nui. Mo nga momo hua rereke, kei ia taiao nga tikanga whakahaere hou, penei i te pāmahana, te wa, te pehanga me te mana rere rawa. Ko nga taputapu awhina me nga taputapu whakahaere he taurangi pai mo te kounga hua me nga punaha whakaputa pono.

Mai i te mea he rite te mahi o te hydroxypropyl methylcellulose ki etahi atu ethers wairewa-wai, ka taea te whakamahi hei kaihoko hanga kiriata, hei whakakorikori, emulsifier me te whakapumau i roto i te peita latex me nga waahanga peita kapia wairewa.

Hangaia te kiriata paninga kia pai te mau kakahu, te whakataurite me te piri, me te whakapai ake i te maataki o te mata, te pumau ki te waikawa me te kawakawa, me te hototahi ki nga poaka konganuku. He pai te painga o te Hydroxypropyl methylcellulose hei whakakaha mo te peita polyvinyl acetate ma te wai. Ko te tohu o te whakakapinga o te cellulose ether ka piki ake, ka kaha ake ano te aukati ki te horo huakita.
