Mmetụta nke Cellulose Ether na Putty Powder Ngwa

Gịnị bụ ihe mere putty ntụ ntụ na-akpọnwụ ngwa ngwa?

Nke a na-emetụtakarị na mgbakwunye nke calcium ash na njigide mmiri nke eriri, yana metụtara nkụ nke mgbidi.

O doro anya na nke a nwere njikọ na esemokwu elu mmiri nke hydroxypropyl methylcellulose aqueous solution. Esemokwu tebụl mmiri nke ngwọta mmiri hydroxyethyl abụghị ihe doro anya. Ọ ga-adị mma ịmecha ọgwụgwọ.

Kedu ihe kpatara uzuzu putty ji eme ka ọ dị gịrịgịrị ma gbakwunye mmiri?

A na-eji cellulose mee 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.

Ya bụ, viscosity na-ebelata n'okpuru mkpali, na viscosity na-agbake mgbe guzoro.

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

N'okwu a, viscosity nke cellulose a na-ejikarị eme ihe dị 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.

Kedu ihe 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.
