2. Gịnị bụ isi ọrụ nke ngwa nke HPMC na mgbidi putty?
Na mgbidi putty , HPMC nwere ọrụ atọ: njupụta, njigide mmiri na ihe owuwu.
Ọkpụkpụ: Enwere ike ịgbatị cellulose ka ọ kwụsịtụ ma mee ka ngwọta ya bụrụ otu, yana iguzogide sagging. Njide mmiri: mee ka mgbidi ahụ kpoo nwayọọ nwayọọ, ma nyere calcium isi awọ aka imeghachi omume n'okpuru mmiri. Mwube: Cellulose nwere mmetụta mmanu mmanu, nke nwere ike ime ka mgbidi mgbidi na-arụ ọrụ nke ọma.
3. Mbelata nke mgbidi putty metụtara HPMC?
Mbelata nke mgbidi putty na-emetụtakarị àgwà calcium ash, mana ọ bụghị na HPMC. Ọ bụrụ na ọdịnaya calcium nke calcium ash na oke nke CaO na Ca (OH) 2 na calcium ash ezighi ezi, ọ ga-eme ka ntụ ntụ ghara. Ọ bụrụ na ọ nwere ihe jikọrọ ya na HPMC, mgbe ahụ, njigide mmiri na-adịghị mma nke HPMC ga-ebutekwa ntụ ntụ.
4. Ego ole bụ hydroxypropyl methyl cellulose (HPMC) na mgbidi putty?
The ego nke HPMC eji na n'ezie ngwa dịgasị dabere na ihu igwe, okpomọkụ, local ash calcium àgwà, usoro nke mgbidi putty , na "àgwà chọrọ site ahịa". N'ikwu okwu n'ozuzu, n'etiti 4 kg na 5 kg. Dị ka ihe atụ: Beijing mgbidi putty bụ ukwuu n'ime 5 kg; Guizhou na-abụkarị kilogram 5 n'oge ọkọchị yana kilogram 4.5 n'oge oyi; Yunnan dị obere, na-abụkarị kilogram 3 ruo 4 na ihe ndị ọzọ.
5. Gịnị bụ viscosity kwesịrị ekwesị nke hydroxypropyl methyl cellulose (HPMC)?
mgbidi putty na-abụkarị 100,000 , ma ngwa agha na-achọsi ike karị, ọ na-ewekwa 150,000 ịrụ ọrụ. Ọzọkwa, ọrụ kachasị mkpa nke HPMC bụ njide mmiri, na-esote thickening. Na mgbidi mgbidi , ọ bụrụhaala na njide mmiri dị mma, viscosity dị ala (70-80,000), ọ ga-ekwe omume, n'ezie, viscosity dị elu, na njigide mmiri nke ikwu dị mma. Mgbe viscosity karịrị 100,000, viscosity enweghị mmetụta na njide mmiri.
6. Kedu otu esi ahọrọ ezigbo hydroxypropyl methylcellulose (HPMC) maka ebumnuche dị iche iche?
Ngwa nke putty mgbidi : ihe a chọrọ dị ala, viscosity bụ 100,000, o zuru ezu, ihe dị mkpa bụ idobe mmiri ka mma. Ngwa ngwa ngwa: ihe ndị dị elu chọrọ, elu viscosity, mma karịa 150,000, ngwa nke gluu: ngwaahịa na-agbaze ngwa ngwa, nnukwu viscosity.
7. Ngwa nke HPMC na mgbidi mgbidi, gịnị na-eme ka mgbidi mgbidi na-emepụta egosipụta?
HPMC na-arụ ọrụ atọ n'ime mgbidi mgbidi: ịgbara mmiri, njigide mmiri na ihe owuwu. Esokwala na mmeghachi omume ọ bụla. Ihe kpatara afụ:
(1) A na-etinye oke mmiri.
(2) Ala oyi akwa adịghị akpọnwụ, a na-ehichapụkwa oyi akwa ọzọ na ya, nke dịkwa mfe ịfụfụ.
