Mgbe anyị na-eji ntụ ntụ, a ga-enwekarị nsogbu, n'ihi ya, anyị amaghị ihe kpatara ya. Echere m na ekwesịrị inwe ụdị nsogbu asaa nke na-apụtakarị na ntụ ntụ putty!
Otu: Mee ya ngwa ngwa. Nke a na-emetụtakarị na mgbakwunye nke calcium ash na njigide mmiri nke eriri, yana metụtara nkụ nke mgbidi.
Abụọ: bee na mpịakọta. Nke a metụtara ọnụ ọgụgụ njide mmiri, nke dị mfe ime mgbe viscosity nke cellulose dị ala ma ọ bụ ọnụ ọgụgụ nke mgbakwunye dị ntakịrị.
Atọ: iwepụ ntụ ntụ. Nke a metụtara oke calcium ash agbakwunyere, ọ na-emetụtakwa ego na ogo nke cellulose agbakwunyere. A na-egosipụta ya na ọnụ ọgụgụ njide mmiri nke ngwaahịa ahụ. Ọnụ ọgụgụ njide mmiri dị ala na oge hydration nke calcium ash ezughị.
Anọ: Ọnya. Nke a metụtara iru mmiri akọrọ na ịdị larịị nke mgbidi ahụ, ọ na-emetụtakwa ihe owuwu ahụ.
Ise: Akara ntụtụ pụtara. Nke a metụtara cellulose, nke nwere ihe na-emepụta ihe nkiri na-adịghị mma. N'otu oge ahụ, adịghị ọcha dị na cellulose na-emeghachi omume ntakịrị na calcium ash. Ọ bụrụ na mmeghachi omume ahụ siri ike, ntụ ntụ putty ga-apụta na ọnọdụ nke ihe fọdụrụ na bean curd. Enweghị ike itinye ya na mgbidi, ọ nweghịkwa ike jikọrọ ọnụ n'otu oge ahụ. Tụkwasị na nke a, ọnọdụ a na-emekwa na ngwaahịa ndị dị ka otu carboxyl agbakwunyere na cellulose.
Isii: Ọgba mgbawa ugwu na obere oghere pụtara. O doro anya na nke a na-ejikọta ya na esemokwu elu mmiri nke hydroxypropyl methylcellulose aqueous solution, ma mmiri dị n'elu mmiri nke hydroxyethyl aqueous solution abụghị ihe doro anya. Ọ ga-aka mma ịme ọgwụgwọ ọkụ.
Asaa: Mgbe putty kpochara, ọ dị mfe ịgbawa ma gbanwee edo edo. Nke a metụtara mgbakwunye nke nnukwu calcium isi awọ. Ọ bụrụ na agbakwunyere calcium isi awọ nke ukwuu, ike nke ntụ ntụ putty ga-abawanye mgbe ihichachara. Naanị isi ike na enweghị mgbanwe ga-adị mfe ịgbawa, karịsịa ma ọ bụrụ na a na-etinye ya na ike mpụga. Ọ na-emetụtakwa nnukwu ọdịnaya nke calcium oxide na calcium isi awọ.
1. Gịnị mere uzuzu putty ji eme ka ọ dị gịrịgịrị ma gbakwunye mmiri?
A na-eji cellulose ether eme ihe dị ka ihe na-eme ka mmiri na-eme ka mmiri dị na putty. N'ihi thixotropy nke cellulose n'onwe ya, mgbakwunye nke cellulose na ntụ ntụ ntụ na-edugakwa na 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.
2. Gịnị bụ ihe mere putty ji dị arọ na usoro scraping?
N'okwu a, viscosity nke cellulose a na-ejikarị eme ihe dị oke elu. Ụfọdụ ndị na-emepụta ihe na-eji cellulose 200,000 mee putty. Putty a na-emepụta n'ụzọ dị otú a nwere nnukwu viscosity, ya mere ọ na-adị arọ mgbe ọ na-ehichapụ. Ọnụ ego a tụrụ aro maka mgbidi ime bụ 3-5 kg, na viscosity bụ 80,000-100,000.
3. Gịnị mere putty na ngwa agha nke cellulose nwere otu viscosity ji dị iche na oyi na okpomọkụ?
N'ihi gelation thermal nke ngwaahịa ahụ, viscosity nke ngwaahịa ahụ 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 mee ka ọnụ ọgụgụ nke cellulose dịkwuo elu, ma họrọ ngwaahịa nwere okpomọkụ gel dị elu.
