He aha te tikanga whakaputa o te methylcellullose?

He aha te mahi o te methyl cellulose ether i roto i te paru puehu maroke?
A: metyl hydroxyethyl cellulose Ether (mhec) me te methyl hydroxypropyl cellulose Ether (HPMC) methyl cellulose Ether.

I te mara o te paura paura maroke, ko te methyl cellulose ether he rauemi kua whakarerekehia hei paru puehu puehu, hei whakakapi, te raima taapiri, te papa paru, te papa paru. I roto i nga momo paura maroke maroke, ko te tikanga methyl cellulose te nuinga o te mahi mo te pupuri wai me te matotoru.

He aha te tikanga whakaputa o te methylcellullose?
Whakautu: Tuatahi, i te tuatahi, ka pakaru te rauemi matara, katahi ka pania ka toia i raro i te mahi o te houra tiihi. Tāpirihia te Olefin Oxide (penei i te oleylene hāora, te propylene ranei te hāora) me te methyl chloride mo te whakakoi. Hei whakamutunga, ka mahia te horoi horoi wai me te purea me te purea ka whiwhi i te paura ma. Ko tenei paura, ina koa ko te otinga wai, he taonga whakaongaonga. I whakamahia e te Eter te eter i roto i te ahumahi hanga ko te methyl hydroxyetyl ​​cellulose Ether orthyl celllooxyl ranei (he tohu taapiri ranei te MC. Ko tenei hua ka whai waahi nui ki te mara o te puehu puehu maroke. Te mahi nui.

He aha te pupuri i te wai o te methyl cellulose ether (mc)?
Whakautu: Ko te taumata o te pupuri wai ko tetahi o nga tohu whakahirahira hei ine i te kounga o te methyl cellulose eter, ina koa i te hanganga o te apa angiangi me te paru paru. Ka taea e te aukati wai te aukati i te ahuatanga o te kaha o te kaha o te kaha me te ngau i te maroke me te iti rawa o te hydoration. Ko te pupuri i te wai tino pai o te methyl cellulose Ether i raro i nga tikanga o te pāmahana teitei ko tetahi o nga tohu whakahirahira hei wehe i te mahinga o te methyl cellulose Ether. I raro i nga ahuatanga noa, ka mau tonu te pupuri i te wai o te cellulose methyl noa me nga waahanga o te tinana me te pikinga o te pāmahana. Ka piki te pāmahana ki te 40 ° C, ka tino whakaitihia te pupuri i te wai o te Cellulose methyl wai, he mea nui ki nga waahanga wera me te maroke. Na ko te hanga-aparu-paparanga i runga i te ra paki i te raumati ka whai paanga nui. Heoi, ko te hanga mo te kore pupuri wai i roto i te inenga nui ka nui te tirohanga o te rauemi e tika ana ki te inenga teitei, ka raru te hanga.

He mea nui te pupuri i te wai kia pai ai te whakahaere i nga mahi whakapakeketanga o nga punaha whakatipu kohuke. I raro i te mahi a Celllose Eter, ka tukuna te makuku ki te paparanga turanga, te hau ranei mo te waa roa, na reira ka roa te waa ki te taunekeneke i te wai me te kaha.
