Usoro maka iji hydroxyethyl cellulose na agba latex

Ojiji hydroxyethyl cellulose na agba latex bụ nke a: 1. Tinye ozugbo mgbe ị na-egweri pigmenti: usoro a dị mfe, na oge ejiri dị mkpụmkpụ. Usoro zuru ezu bụ ndị a: (1) tinye mmiri dị ọcha nke ọma (nke a na-ejikarị ethylene glycol, onye na-ahụ maka mmiri mmiri na onye na-emepụta ihe nkiri na-agbakwunye n'oge a) (2) malite ịkpali na obere ọsọ na-aga n'ihu ma jiri nwayọọ nwayọọ tinye hydroxyethyl cellulose (3) nọgide na-akpalite ruo mgbe ihe niile dị mmiri (4) tinye ihe mgbochi mildew; PH regulator, wdg (5) nwuo ruo mgbe niile hydroxyethyl cellulose kpamkpam etisasịwo (ihe ngwọta viscosity abawanye) tupu agbakwunyere ndị ọzọ mmiri nke usoro, egweri ruo mgbe agba.
2.Equipped na nne mmanya na-eche maka ojiji: usoro a na mbụ onwem na a elu ịta nke nne mmanya, na mgbe ahụ gbakwunyere na latex agba, usoro a nwere uru nke ukwuu mgbanwe, nwere ike ozugbo kwukwara agba ngwaahịa, ma ga-abụ. echekwara nke ọma. Usoro na ụzọ ndị ahụ yiri nzọụkwụ (1) - (4) na usoro 1, ma e wezụga na ọ dịghị mkpa ka onye na-eme ihe na-eme ka ọ dị elu, ma ọ bụ naanị onye na-eme ihe ike nwere ike zuru ezu iji mee ka eriri hydroxyethyl gbasasịa n'otu n'otu na ngwọta achọrọ. Na-akpali akpali ruo mgbe ọ na-agbaze kpamkpam n'ime ngwọta viscous. Ekwesịrị iburu n'uche na: a ga-agbakwunye ihe mgbochi mildew na mmanya nne ozugbo enwere ike. 3. Congee na phenology: dị ka organic solvents maka hydroxyethyl cellulose bụ a ọjọọ mgbaze, otú ndị a organic solvents nwere ike iji kwadebe congee. Ihe mgbaze ndị a na-ejikarị eme ihe dị ka ethylene glycol, propylene glycol, na ndị na-emepụta ihe nkiri (dị ka hexanediol ma ọ bụ diethylene glycol butyl acetate), 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 ozugbo na agba. Hydroxyethyl cellulose agbachaala nke ọma na porridge. Mgbe agbakwunyere lacquer, ọ na-agbaze ozugbo ma na-agbaze. Mgbe agbakwunyere, a ga-emegharị ya mgbe niile ruo mgbe hydroxyethyl cellulose na-agbaze kpamkpam na edo. N'ozuzu, porridge nwere akụkụ isii nke ihe mgbaze organic ma ọ bụ mmiri ice na akụkụ nke ngwakọta hydroxyethyl cellulose, ihe dị ka nkeji 5-30 ka e mesịrị, hydroxyethyl cellulose ga-hydrolyzed na ọzịza. N'oge okpomọkụ mgbe izugbe mmiri iru mmiri dị oke, ọ bụghị adabara na porridge kwadoro.
3.Anọ. Rịba ama mgbe ị na-akwadebe mmanya nne nke hydroxyethyl cellulose ebe ọ bụ na hydroxyethyl cellulose bụ ihe a na-edozi ntụ ntụ, ọ dị mfe iji rụọ ọrụ na igbari n'ime mmiri site na ịṅa ntị na ihe ndị a. 1 tupu na mgbe agbakwunyere hydroxyethyl cellulose, ngwakọta a ga-akpalite na-aga n'ihu ruo mgbe ngwọta ahụ zuru oke ma doo anya. 2 ga-egweri n'ime agwakọta drum, enweghị ọnụ ọgụgụ buru ibu nke lumps ma ọ bụ bọọlụ nke hydroxyethyl cellulose agbakwunyere ozugbo n'ime agwakọta drum. 3 solubility nke hydroxyethyl cellulose metụtara mmiri okpomọkụ na pH uru na mmiri, nke kwesịrị ịkwụ ụgwọ pụrụ iche. 4 etinyela ụfọdụ ihe ndị bụ isi na ngwakọta tupu hydroxyethyl cellulose ntụ ntụ jupụta na mmiri.
