[Ọgba mgbawa na pinholes na-apụta] O doro anya na nke a metụtara esemokwu elu mmiri nke hydroxypropyl methylcellulose (HPMC) ngwọta mmiri.Esemokwu tebụl mmiri nke ngwọta mmiri hydroxyethyl abụghị ihe doro anya.Ọ ga-adị mma ịmecha ọgwụgwọ.

[Petty dị mfe ịgbawa ma gbanwee edo edo mgbe akpọnwụchara] Nke a metụtara mgbakwunye nnukwu ntụ ntụ calcium ntụ.Ọ bụrụ na a na-agbakwunye ntụ ntụ calcium ash nke ukwuu, ike nke ntụ ntụ putty ga-abawanye mgbe ihichachara.Naanị isi ike na-enweghị mgbanwe ga-adị mfe ịgbawa, karịsịa O yikarịrị ka ọ ga-agbawa mgbe ejiri ike mpụga.Ọ na-ejikọta ya na nnukwu ọdịnaya calcium oxide na ntụ calcium ash.

2. Gịnị mere uzuzu putty ji eme ka ọ dị gịrịgịrị ma gbakwunye mmiri?

A na-eji Hydroxypropyl methylcellulose (HPMC) mee ihe dị ka ihe na-ejupụta na ihe na-ejigide mmiri na griiz.N'ihi thixotropy nke hydroxypropyl methylcellulose (HPMC), hydroxypropyl methylcellulose na putty ntụ ntụ Mgbakwunye nke HPMC mekwara thixotropy mgbe agbakwunyere mmiri na putty.Nke a na-akpata thixotropy site na nbibi nke usoro ejikọtara na-adịghị mma nke ihe ndị dị na ntụ ntụ putty.Ihe owuwu a na-ebilite na izu ike ma daa n'okpuru nrụgide.Ya bụ, viscosity na-ebelata n'okpuru mkpali, na viscosity na-agbake mgbe guzoro.

3. Gịnị bụ ihe mere putty ji dị arọ na usoro scraping?

N'okwu a, viscosity nke hydroxypropyl methylcellulose (HPMC) a na-ejikarị eme ihe dị oke elu, ụfọdụ ndị na-emepụta na-ejikwa yuan 200,000 mee putty.Ihe a na-emepụta n'ụzọ dị otú a nwere nnukwu viscosity, n'ihi ya, ọ ga-emikpu mgbe ogbe scraping.mmetụta nke.Ọnụ ego a tụrụ aro maka mgbidi ime bụ 3-5 kg, na viscosity bụ 80,000-100,000.

4. Gịnị mere i ji chee na viscosity nke hydroxypropyl methylcellulose (HPMC) na otu viscosity dị iche na oyi na okpomọkụ?

N'ihi gelation thermal nke ngwaahịa ahụ, viscosity nke putty na ngwa agha ga-eji nwayọọ nwayọọ belata na mmụba nke okpomọkụ.Mgbe ọnọdụ okpomọkụ karịrị gel okpomọkụ nke ngwaahịa ahụ, ngwaahịa ahụ ga-esi na mmiri pụta ma hapụ viscosity ya.Okpomọkụ ụlọ n'oge okpomọkụ na-adịkarị karịa ogo 30, nke dị nnọọ iche na okpomọkụ n'oge oyi, ya mere viscosity dị ala.A na-atụ aro ka ịhọrọ ngwaahịa nwere viscosity dị elu mgbe ị na-etinye ngwaahịa ahụ n'oge okpomọkụ, ma ọ bụ ịbawanye ụba nke hydroxypropyl methylcellulose (HPMC), na ịhọrọ ngwaahịa nwere okpomọkụ gel dị elu.
