Otu esi eji hydroxyethyl cellulose na agba latex

1. Tinye ozugbo mgbe ị na-egweri pigmenti: Usoro a bụ nke kachasị mfe ma na-ewe obere oge.Usoro zuru ezu bụ ndị a:

(1) Tinye mmiri dị ọcha kwesịrị ekwesị na vat nke onye na-eme ihe dị elu (n'ozuzu, ethylene glycol, onye na-ahụ maka mmiri mmiri na onye na-emepụta ihe nkiri na-agbakwụnye n'oge a)

(2) Malite na-akpali akpali mgbe niile na obere ọsọ ma jiri nwayọọ nwayọọ tinye hydroxyethyl cellulose

(3) Gaa n'ihu na-akpalite ruo mgbe etinyere ihe niile

(4) Tinye ihe na-egbu egbu, PH adjuster, wdg.

(5) Na-akpali ruo mgbe niile hydroxyethyl cellulose na-agbaze kpamkpam (viscosity nke ngwọta na-abawanye nke ukwuu) tupu ịgbakwunye ihe ndị ọzọ na usoro ahụ, na-egweri ruo mgbe ọ na-aghọ agba.

2. Kwadebe mmanya na-egbu nne maka ojiji: Usoro a bụ ịkwadebe mmanya nne na-etinye uche dị elu, wee tinye ya na agba latex.Uru nke usoro a bụ na ọ nwere mgbanwe dị ukwuu ma nwee ike itinye ya ozugbo na agba agbachachara, ma a ghaghị ịchekwa ya nke ọma.Usoro na ụzọ ndị ahụ yiri nzọụkwụ (1) - (4) na usoro 1, ihe dị iche bụ na ọ dịghị mkpa maka onye na-eme ihe ike dị elu, ọ bụ 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-ahụ maka antifungal na nne mmanya ozugbo enwere ike.

3. N'ihi na porridge phenology: Ebe ọ bụ na organic solvents bụ ogbenye ihe mgbaze maka hydroxyethyl cellulose, ndị a organic solvents nwere ike iji kwadebe porridge.Ihe mgbaze ndị a na-ejikarị eme ihe dị ka ethylene glycol, propylene glycol, na ndị na-emepụta ihe nkiri (dị ka hexylene glycol ma ọ bụ diethylene glycol butyl acetate), mmiri ice bụkwa ihe mgbaze na-adịghị mma, ya mere a na-ejikarị mmiri mmiri eme ihe na mmiri mmiri.Iji kwadebe porridge.

Enwere ike ịgbakwunye porridge dị ka hydroxyethyl cellulose na agba.Mmiri hydroxyethyl cellulose agbachaala nke ọma na porridge.Mgbe etinyere ya na agba, ọ na-agbaze ozugbo wee gbazee.Mgbe agbakwunyere, a ga-emegharị ya mgbe niile ruo mgbe hydroxyethyl cellulose na-agbaze kpamkpam na edo.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.N'oge okpomọkụ, iru mmiri nke mmiri n'ozuzu dị oke elu, ọ dịghịkwa mma ka e jiri ya mee ihe maka porridge.

4. Ihe dị mkpa nlebara anya mgbe ị na-akwadebe hydroxyethyl cellulose nne mmanya

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 agbakwunyere hydroxyethyl cellulose, ọ dị mkpa ịnọgide na-akpali akpali ruo mgbe ngwọta ahụ zuru oke ma doo anya.

2) A ghaghị ịgbanye ya n'ime gbọmgbọm agwakọta nwayọọ nwayọọ, ma tinyela hydroxyethyl cellulose nke emebere ka ọ bụrụ lumps ma ọ bụ bọọlụ ozugbo n'ime gbọmgbọm agwakọta.

3) Mmiri mmiri na uru pH dị na mmiri nwere mmekọrịta dị ịrịba ama na mgbasa nke hydroxyethyl cellulose, ya mere a ga-akwụ ụgwọ nlebara anya pụrụ iche na ya.

4) Akwụsịla ihe ụfọdụ alkaline na ngwakọta tupu a na-etinye ntụ ntụ hydroxyethyl cellulose na mmiri.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, ntinye nke mmanya nne ekwesịghị ịdị elu karịa 2.5-3% (site na ibu), ma ọ bụghị ya, ọ ga-esiri ike ijide ya.
