Kedu otu esi eji Hydroxyethyl cellulose na agba latex?

Hydroxyethyl cellulosea na-ejikarị agba latex, agba emulsion & mkpuchi, ka esi eji Hydroxyethyl cellulose na agba latex?

1. Tinye ozugbo na pigmenti abrasive

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-agbakwunye n'oge a)

(2) Malite ịkpali na obere ọsọ ma jiri nwayọọ nwayọọ tinye hydroxyethyl cellulose

(3) na-aga n'ihu na-akpali ruo mgbe ihe niile dị mmiri

(4) Na-agbakwunye ihe mgbochi mildew, pH adjuster, wdg.

(5)Gwakọta ruo mgbe niile hydroxyethyl cellulosena-agbaze kpam kpam (viscosity nke ngwọta na-abawanye nke ukwuu) tupu ị gbakwunye ihe ndị ọzọ na nhazi na ichikota ruo mgbe e guzobere lacquer.

2. kwadoro nne mmanya

A na-ebu ụzọ kwadebe usoro a n'ụdị mmanya dị elu nke nne ma tinyezie ya na agba latex.Uru nke usoro a bụ na ọ nwere mgbanwe dị ukwuu ma nwee ike ịgbakwunye ya ozugbo na agba agbachachara, ma a ghaghị ịchekwa ya nke ọma.Usoro na ụzọ ndị ahụ yiri nzọụkwụ (1) - (4) na Usoro 1, ma e wezụga na onye na-akpali akpali adịghị mkpa ka ọ dị elu, ma ọ bụ naanị onye na-akpali akpali nwere ike zuru ezu iji mee ka eriri hydroxyethyl gbasasịa n'otu n'otu na ngwọta. .nwere ike.Gaa n'ihu na-akpalite ruo mgbe agbazere kpamkpam n'ime ngwọta viscous.Ekwesiri ighota na a ga-agbakwunye onye na-eme ihe na-akpụ akpụ na mmanya nne ozugbo enwere ike.

3. na porridge

Ebe ọ bụ na ihe mgbaze organic bụ ihe na-adịghị mma maka hydroxyethyl cellulose, a pụrụ iji ihe ndị a na-emepụta ihe na-emepụta ihe na-emepụta ihe na-edozi ahụ.Ihe mgbaze ndị a na-ejikarị eme ihe dị ka ethylene glycol, propylene glycol, na ndị na-eme ihe nkiri (dị ka hexane ma ọ bụ diethylene glycol butyl acetate), mmiri ice bụkwa ihe mgbaze na-adịghị mma, ya mere, a na-ejikarị mmiri mmiri na mmiri mmiri eme ihe. porridge.Enwere ike ịgbakwunye porridge dị ka hydroxyethyl cellulose na agba.Hydroxyethyl cellulose agbanyela nke ọma na porridge.Mgbe etinyere ya na agba, ọ na-agbaze ozugbo wee sie ike.Mgbe mgbakwunye ahụ gasịrị, ọ dị mkpa ka ị na-aga n'ihu ruo mgbe hydroxyethyl cellulose na-agbaze kpamkpam ma na-ejikọta ya.N'ozuzu, a na-agwakọta porridge na akụkụ nke ihe mgbaze organic ma ọ bụ mmiri ice na akụkụ nke hydroxyethyl cellulose.Mgbe ihe dị ka nkeji 5 ruo 30 gachara, hydroxyethyl cellulose na-agbapụta ma na-ebili n'ụzọ dị ịrịba ama.N'ozuzu, iru mmiri nke mmiri n'oge okpomọkụ dị oke elu ma ghara iji ya mee ihe maka porridge.

4. Akpachara anya mgbe ị na-eji hydroxyethyl cellulose nne mmanya

Ebe ọ bụ na hydroxyethyl cellulose (HEC)bụ granule a na-agwọ, ọ dị mfe ijikwa na igbari na mmiri ma ọ bụrụhaala na achọpụtara ihe ndị a.

(1) Tupu na mgbe mgbakwunye nke hydroxyethylcellulose, mkpali ga-aga n'ihu ruo mgbe ngwọta bụ kpamkpam doro anya na doro anya.

(2) A ghaghị iji nwayọọ nwayọọ gbanye ya n'ime tankị ngwakọta.Agbakwunyela hydroxyethyl cellulose nke emebere ka ọ bụrụ ngọngọ na ọdịdị okirikiri ozugbo n'ime tankị ngwakọta.

(3) Mmiri mmiri na pH uru dị na mmiri nwere mmekọrịta dị ịrịba ama na mgbasa nke hydroxyethyl cellulose, na a ghaghị ilekọta nlekọta pụrụ iche.

(4) Agbakwunyela ihe ụfọdụ alkaline na ngwakọta tupu mmiri na-eteta ntụ ntụ hydroxyethyl cellulose.Ịbawanye pH mgbe ịsachara na-enyere aka igbari.

(5) Tinye ihe mgbochi ebu ozugbo enwere ike.

(6) Mgbe ị na-eji nnukwu viscosity hydroxyethyl cellulose, ịta mmanya nne ekwesịghị ịdị elu karịa 2.5-3% (site n'ịdị arọ), ma ọ bụghị ya siri ike ijikwa mmanya nne.
