Te rewa wai wera: na te mea karekau te HPMC i roto i te wai wera e rewa, no reira ka taea te marara te HPMC i roto i te hononga taketake ki te wai wera, ka tere te rewa ina whakamatao. Ko nga huarahi tawhito e rua e whakaahuahia ana e whai ake nei:
1) Kuhua te wai wera e hiahia ana koe ki roto i te ipu ka whakamahana ki te 70 ℃. Whakaranuhia, ata taapirihia te hydroxypropyl methyl cellulose, ka tere haere te HPMC ki runga i te awa, katahi ka ata whakaputa i te paru whakamatao ki roto i te whakaranu.
2) Whakauruhia te 1/3, te 2/3 ranei o te wai ki roto i te ipu, whakamahana ki te 70 ℃, whakamahana ki te 70 ℃ hei whakamarara i te HPMC, me te whakarite i te wai wera; Ko te toenga o te wai matao ka tapirihia ki te paru wera ka konatunatua ki te ranunga i muri i te whakamatao.
Tikanga whakaranu i te paura: Ko te paura HPMC me te whakaranu me te maha atu o nga mea matū paura he ranea te ranunga, katahi ka tapirihia he wai kia memeha. I tenei wa, ka taea te rewa HPMC i roto i te take o te kore agglomeration, no te mea he iti noa HPMC paura ia kokonga iti, ina ka memeha tonu te wai - tenei ahua o te ara ko te tono noa o te paura putty taiepa roto me kaihanga kumete. [HPMC] hei kaihoko whakakoi me te makuku i roto i te kumete putty o te pakitara o roto.
Ko te hydroxypropyl methyl cellulose (HMPC) he roimata horihori, e tata ana ki te matū viscoelastic (te nuinga o te mucin) i roto i nga roimata. Ka piri ki te mata o te kanohi na roto i te whakauru o te polymer, ka whakataurite i te mahi o te mucin conjunctival, kia pai ake ai te heke o te mucin i roto i te kanohi me te whakanui ake i te makuku o te kiore.
I roto i te paura putty, te matotoru, te pupuri wai me te hanga o nga mahi e toru. Ko te matotoru, ka taea te whakakakahu i te cellulose ki te whakatārewatanga, kia noho rite tonu te otinga ki runga me raro ki te mahi o te iri aukati. Te pupuri wai: kia maroke te paura putty, hei awhina i te konupūmā hina i roto i te mahi o te tauhohenga wai. Hanganga: whakahinuhinu cellulose, ka taea te hanga putty paura he hanga pai. Karekau a HPMC e uru ki nga tauhohenga matū, engari he mahi tautoko anake.
Ko te peita kakano he ngawari ake i roto i te kowhiringa o te tae, a ka taea te whakatutuki i te painga o te hoahoa toi pai, me te peita kohatu tuuturu i roto i te whai i te ahua ora maori, he pai ake i te peita kakano, kei ia tangata ona ake kaha. Te peita kakano me te lacquer i roto i te tukanga whakaputa, kia mau tonu ai te tae taketake, te tikanga i roto i te mahi whakamutunga, me whakamahi tatou i te parani (hinu marama) ki te rehu ki te tiaki i o raatau mahi toi, te hua kohatu ranei.
Lacquer, kakano peita he momo peita, te nuinga whakamahia mo te whakapaipai taiepa. Ko te paetukutuku mana o te paru diatom taiao e whakarāpopoto ana i ētahi rerekētanga i waenga i te peita kakano me te kakano, te peita kakano me te tikanga wehewehe, ko enei e whai ake nei hei kite i te rereketanga o te peita kakano me te peita kakano.
Ko te kounga teitei o te taherapa utu nui, nga kaihanga ki te penapena i nga utu, me tapiri noa he iti o te wahanga o te whakaehunga, i muri i te hanga i te peita kohatu hei whakamaroke i te kiriata maroke, kaore i te nui te kiato, ko te kiriata peita he nui ake te reeti bibulous, ka heke te kaha o te pupuhi, ka tutaki te ua mo te wa roa, ka uru te ua ki roto i te kiriata peita, he peita kohatu ma.
Ētahi kaihanga i roto i te hanga o te lacquer, maha tāpiri he rota o te carboxymethyl cellulose, hydroxyethyl cellulose rite te thickener, enei matū he wai-wairewa hydrophilic ranei, paninga kiriata mahue i roto i te apa, tino whakaiti i te ātete wai o te paninga.
