Nsogbu na ojiji nke methyl cellulose

Methyl cellulose bụ mbiri nke sodium carboxymethyl cellulose.A na-ejikarị ya na nri, ihe owuwu, ọgwụ, ceramik, batrị, ngwuputa ihe, mkpuchi, ịsa akwụkwọ, ịsacha, ihe ntacha eze kwa ụbọchị, textile na akwa ákwà, mkpọ mmanụ, wdg n'ime ubi.Isi ọrụ bụ ime ihe dị ka a thickener, mmiri na-ejigide gị n'ụlọnga, ihe nkedo, mmanu mmanu, suspending gị n'ụlọnga, emulsifier, ndu ngwaahịa ụgbọelu, mbadamba matrix, wdg Olee otú methyl cellulose ga-proportioned n'oge eji?

1. Methylcellulose n'onwe ya bụ ntụ ntụ na-acha ọcha, nke a na-apụghị iji mee ihe ozugbo na ụlọ ọrụ ahụ.A ga-ebu ụzọ gbaze ya n'ime mmiri ka ọ bụrụ gluu na-enweghị atụ tupu a gwakọta ya na ngwa agha wee jiri ya mee ihe maka ọgwụgwọ ụfọdụ, dị ka taịlị taịlị.

2. Gịnị bụ oke nke methyl cellulose?Ntụ ntụ: mmiri kwesịrị ka a na-edozi ya n'otu oge dị ka nha nke 1: 150-200 si dị, wee mee ka ọ bụrụ artificially, mgbe ị na-agbakwunye PMC akọrọ ntụ ntụ mgbe ị na-akpali, na enwere ike iji ya mgbe ihe dị ka elekere 1 gasịrị.

3. Ọ bụrụ na a na-eji methyl cellulose mee ihe maka ọgwụgwọ interface ihe, nhazi nke gluu kwesịrị ịgbaso → gluu: ciment = 1: 2.

4. Ọ bụrụ na a na-eji methyl cellulose mee ihe dị ka ụrọ simenti iji guzogide mgbawa, ọ dị mkpa ka a na-agbaso usoro gluu → gluu: ciment: ájá = 1: 3: 6.

Anyị kwesịrị ịṅa ntị na nsogbu ụfọdụ mgbe ị na-eji methyl cellulose:

1. Tupu iji methyl cellulose mee ihe, ị ga-ebu ụzọ lelee nkọwapụta na ụdị.Ụdị dị iche iche na-eji ụzọ dị iche iche: mgbe pH> 10 ma ọ bụ <5, viscosity nke gluu dị ntakịrị.Arụmọrụ bụ nke kacha kwụsie ike mgbe pH = 7, na viscosity ga-ebili ngwa ngwa mgbe okpomọkụ dị n'okpuru 20 ° C;mgbe okpomọkụ dị n'elu 80 Celsius C, colloid ga-denatured mgbe ogologo oge kpo oku, ma viscosity ga-ada nke ukwuu.

2. Methyl cellulose nwere ike kwadebere ya na mmiri oyi ma ọ bụ mmiri ọkụ dị ka nhazi edozi.Mgbe ị na-akwadebe, ịkwesịrị ịgbakwunye mmiri mgbe ị na-akpali.Cheta ịgbakwunye mmiri niile na PMC ntụ ntụ n'otu oge.Okwesiri iburu n'uche na a ga-ehichapụ akwa oyi akwa nke kwesịrị ijikọ tupu oge eruo, a ga-edozikwa ụfọdụ unyi, ntụpọ mmanụ, na akwa akwa akwa na oge.
