Otu esi eji hydroxyethyl cellulose na agba latex
1. Hydroxyethyl cellulose na-eji eme 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 itinye porridge dị ka hydroxyethyl cellulose na agba latex ozugbo.Hydroxyethyl cellulose agbanyela nke ọma na porridge.Mgbe etinyere ya na agba, ọ na-agbaze ngwa ngwa ma na-eme ihe dị ka ihe na-esi ísì ụtọ.Mgbe ịgbakwunye, na-akpalite ruo mgbe hydroxyethyl cellulose na-agbasasị kpamkpam ma gbazee.N'ozuzu, a na-eme porridge site na ịgwakọta 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, hydroxyethyl cellulose ga-agbaze ma zaa nke ọma.(Cheta na iru mmiri nke mmiri izugbe dị oke elu n'oge ọkọchị, yabụ na e kwesịghị iji ya kwadebe porridge.)
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 n'ime nnukwu ịwụ nke igwekota akwa (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 ihe niile na-agbasasị ma tinye ya
(4) Tinye mgbakwunye mgbochi mildew 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 ahụ, na-egweri ruo mgbe agbachara.
3. Kwadebe hydroxyethyl cellulose na nne mmanya maka ime emechaa: 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 ịgbakwunye ya ozugbo na agba agbachachara, ma a ghaghị ịchekwa ya nke ọma..Usoro na usoro yiri nzọụkwụ (1) - (4) na usoro 2, ihe dị iche bụ na ọ dịghị onye na-eme ihe dị elu dị mkpa, ọ bụ naanị ụfọdụ ndị na-agba ume nwere ike zuru ezu iji mee ka eriri hydroxyethyl gbasasịa n'otu n'otu na ngwọta bụ Can. .Gaa n'ihu na-akpali akpali 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 ya na mmiri ma ọ bụrụhaala na a na-elebara ihe ndị a anya.
(1) Tupu na mgbe agbakwunyere hydroxyethyl cellulose, a ga-emerịrị ya mgbe niile ruo mgbe ngwọta ya zuru oke ma doo anya.
(2) A ghaghị iji nwayọọ nwayọọ gbanye ya n'ime tankị ngwakọta, ma etinyela ya ozugbo nnukwu hydroxyethyl cellulose nke mebere lumps ma ọ bụ bọọlụ n'ime tankị ngwakọta.
(3) Mmiri mmiri na uru pH dị na mmiri nwere mmekọrịta dị ịrịba ama na mgbasa nke hydroxyethyl cellulose, ya mere, a ghaghị 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 mgbe a kpochapụrụ ihe na-enyere aka mgbasa.
(5) Dị ka o kwere mee, tinye ọgwụ mgbochi fungal n'oge.
(6) Mgbe ị na-eji hydroxyethyl cellulose viscosity dị elu, ntinye nke 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) N'ihi oke mkpali, iru mmiri na-ekpo oke ọkụ n'oge mgbasa.
(2) Ọnụ ọgụgụ nke ihe ndị ọzọ eke eke na agba agba na ruru nke ego na hydroxyethyl cellulose.
(3) Ma ọnụọgụ nke surfactant na oke mmiri ejiri mee ihe n'usoro agba kwesịrị ekwesị.
(4) Mgbe ị na-emepụta latex, ọnụọgụ nke ọdịnaya oxide dị ka ihe na-emepụta ihe.
(5) Corrosion nke thickener site microorganisms.
(6) N'ime usoro agba, ma usoro nke ịgbakwunye thickener kwesịrị ekwesị.
7 Ka ikuku ikuku na-anọgide na agba, otú ahụ ka viscosity dị elu
