Otu esi eji hydroxyethyl cellulose na agba latex
1. Hydroxyethyl cellulose na-eji kwadebe porridge: Ebe ọ bụ na hydroxyethyl cellulose adịghị mfe igbari na organic solvents, ụfọdụ organic solvents nwere ike iji kwadebe porridge.Mmiri ice bụkwa ihe mgbaze na-adịghị mma, n'ihi ya, a na-ejikarị mmiri mmiri eme ihe iji kwadebe porridge.Enwere ike ịgbakwunye porridge dị ka hydroxyethyl cellulose na agba latex.Mmiri hydroxyethyl cellulose agbachaala nke ọma na porridge.Mgbe etinyere ya na agba, ọ na-agbaze ngwa ngwa ma na-arụ ọrụ na-agbari.Mgbe agbakwunyere, ọ ka dị mkpa ịnọgide na-akpalite ruo mgbe hydroxyethyl cellulose na-agbasasị kpamkpam ma gbazee.N'ozuzu, a na-agwakọta porridge na akụkụ isii nke ihe mgbaze organic ma ọ bụ mmiri ice na otu akụkụ nke hydroxyethyl cellulose.Mgbe ihe dị ka nkeji 5-30 gachara, a ga-agbaze hydroxyethyl cellulose ma zaa nke ọma.(A na-atụ aro na iru mmiri nke mmiri izugbe dị oke elu n'oge okpomọkụ, n'ihi ya, ọ dịghị mma ka a na-eji porridge mee ihe.)
2. Tinye hydroxyethyl cellulose ozugbo mgbe ị na-egweri pigmenti: Usoro a dị mfe ma na-ewe obere oge.Usoro zuru ezu bụ nke a:
(1) Tinye mmiri dị ọcha kwesịrị ekwesị na vat nke onye na-eme ihe nkiri dị elu (n'ozuzu, a na-agbakwunye ihe ndị na-emepụta ihe nkiri na ndị na-eme mmiri mmiri n'oge a)
(2) Malite na-akpali akpali na-aga n'ihu na obere ọsọ ma jiri nwayọọ nwayọọ na ọbụna tinye hydroxyethyl cellulose
(3) Gaa n'ihu na-akpalite ruo mgbe a na-agbasasị akụkụ niile ma tinye ya
(4) Tinye mgbakwunye antifungal iji mezie uru PH
(5) Na-akpali ruo mgbe niile hydroxyethyl cellulose na-agbaze kpamkpam (viscosity nke ngwọta na-abawanye nke ukwuu), tinyezie ihe ndị ọzọ na usoro, na-egweri ruo mgbe ọ na-aghọ agba.
3. Kwadebe hydroxyethyl cellulose na nne mmanya maka ojiji: Usoro a bụ ịkwadebe mmanya nne na-etinye uche dị elu na mbụ, wee tinye ya na agba latex.Uru nke usoro a bụ na ọ na-agbanwe agbanwe ma nwee ike tinye ya ozugbo na agba agbachachara, ma ọ dị mkpa ka echekwara ya nke ọma..Usoro na usoro dị ka usoro (1) - (4) na usoro 2, ihe dị iche bụ na ọ dịghị mkpa maka onye na-eme ihe ike dị elu, na naanị ụfọdụ ndị na-eme ihe ike nwere ike zuru ezu iji mee ka eriri hydroxyethyl gbasasịa n'otu n'otu. A na-eji ngwọta eme ihe.Nwere ike.Na-aga n'ihu na-akpali akpali mgbe niile ruo mgbe agbazere kpamkpam n'ime ngwọta viscous.Ekwesiri iburu n'uche na a ga-agbakwunye onye na-eme ihe na-eme ihe na-egbu egbu n'ime ihe ọṅụṅụ nne agba ozugbo enwere ike.
4 Ihe dị mkpa nlebara anya mgbe ị na-akwadebe mmanya nne hydroxyethyl cellulose
Ebe ọ bụ na hydroxyethyl cellulose bụ ntụ ntụ edozi, ọ dị mfe ijikwa na igbari n'ime mmiri ma ọ bụrụhaala na achọpụtara ihe ndị a.
(1) Tupu na mgbe ịgbakwunye hydroxyethyl cellulose, ọ ga-anọgide na-akpali akpali ruo mgbe ngwọta bụ kpamkpam transperent na doro anya.
(2) A ghaghị ịgbanye ya n'ime gbọmgbọm agwakọta nwayọọ nwayọọ.E tinyekwala cellulose hydroxyethyl ozugbo ka ọ bụrụ lumps na bọọlụ n'ime gbọmgbọm agwakọta n'ọtụtụ ma ọ bụ ozugbo.
(3) Mmiri mmiri na pH uru na mmiri nwere mmekọrịta dị ịrịba ama na mgbasa nke hydroxyethyl cellulose, ya mere e kwesịrị ịkwụ ụgwọ nlebara anya pụrụ iche.
(4) E tinyela ihe ụfọdụ alkaline na ngwakọta tupu e tinye ya na mmiri hydroxyethyl cellulose ntụ ntụ.Ịkwalite pH naanị mgbe ịsachara mmiri ga-enyere aka na mgbasa.
(5) Dị ka o kwere mee, tinye onye na-ahụ maka antifungal ozugbo enwere ike.
(6) Mgbe ị na-eji hydroxyethyl cellulose viscosity dị elu, ịta mmanya nne ekwesịghị ịdị elu karịa 2.5-3% (site na ibu), ma ọ bụghị ya, ọ ga-esiri ike ijide ya.
Ihe ndị na-emetụta viscosity nke agba latex:
(1) Iru mmiri na-ekpo oke ọkụ n'oge mgbasa n'ihi oke mkpali.
(2) Usoro onunu ogwu nke ndi ozo eke na usoro onunu ogwu nke hydroxyethyl cellulose na usoro agba.)
(3) Ma ọnụọgụ nke surfactant na oke mmiri dị n'ụdị agba kwesịrị ekwesị.
(4 Mgbe ị na-emepụta latex, ọnụ ọgụgụ nke residual catalyst na ndị ọzọ oxides.
5 Microbial ozize nke thickeners.
6 N'oge a na-eme agba, usoro nke usoro maka ịgbakwunye thickeners dabara adaba?
7 Ọdịnaya dị elu nke afụ ikuku fọdụrụ na agba, ka viscosity dị elu
