1. Nsogbu nkịtị na putty ntụ ntụ

[Nhicha ngwa ngwa] Nke a na-emetụta ya na ọnụọgụ calcium ntụ ntụ agbakwunyere (oke buru ibu, ọ nwere ike ibelata oke ntụ ntụ calcium nke a na-eji na usoro putty) na ọnụego njigide mmiri nke hydroxypropyl methylcellulose (HPMC), na ya. a na-ejikọta ya na ya metụtara nkụ nke mgbidi.

[Skinning na curling] Nke a metụtara ọnụego njide mmiri. Hydroxypropyl methylcellulose (HPMC) nwere obere viscosity na ọ na-adịkarị mfe na ọnọdụ a ma ọ bụ ọnụ ọgụgụ nke mgbakwunye dị ntakịrị.

[Nwepụ ntụ ntụ nke ime mgbidi putty ntụ ntụ] Nke a metụtara ọnụọgụ ntụ ntụ calcium agbakwunyere (ọnụọgụ ash calcium ntụ ntụ na usoro putty dị ntakịrị ma ọ bụ ịdị ọcha nke ntụ ntụ calcium dị ntakịrị, na ọnụ ọgụgụ nke ntụ ntụ. calcium powder in the putty powder formula kwesịrị ịba ụba nke ọma) N'otu oge ahụ, ọ na-ejikọta ya na ego na àgwà nke hydroxypropyl methylcellulose (HPMC), nke na-egosipụta na ọnụ ọgụgụ njide mmiri nke ngwaahịa ahụ. Ọnụ ọgụgụ njide mmiri dị ala, na calcium oxide na ntụ ntụ calcium adịghị etinye uche zuru oke Calcium hydroxide ntughari hydration) oge ezughi oke, kpatara ya.

[Blistering] Nke a metụtara iru mmiri akọrọ na ịdị larịị nke mgbidi, ọ na-emetụtakwa ihe owuwu ahụ.

[Pinpoints pụtara] Nke a metụtara cellulose, nke nwere ihe na-emepụta ihe nkiri na-adịghị mma, yanakwa adịghị ọcha dị na hydroxypropyl methylcellulose (HPMC) na-emeghachi omume ntakịrị na calcium ash. Ọ bụrụ na mmeghachi omume ahụ siri ike, ntụ ntụ putty ga-apụta tofu Slag steeti. Enweghị ike itinye ya na mgbidi, ọ nweghịkwa ike jikọrọ ọnụ n'otu oge ahụ. Na mgbakwunye, ngwaahịa ndị dị ka hydroxypropyl methylcellulose (HPMC) jikọtara ya na otu carboxymethyl na-apụtakwa n'ọnọdụ a.

[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 ka 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.
