Ungayisebenzisa kanjani i-Hydroxyethyl cellulose ku-Latex Paint?

IHydroxYethyl CelluloseIsetshenziswa kabanzi ku-latex peint, emulsion paint & izimbobo, ukuthi ungayisebenzisa kanjani i-hydroxyethyl cellulose ku-latex paint?

1. Faka ngqo ku-pubment abrasive

Le ndlela ilula futhi ithatha isikhathi esifushane. Izinyathelo ezinemininingwane zimi ngalendlela elandelayo:

.

(2) Qala ukushukumisa ngejubane eliphansi futhi kancane kancane engeza i-hydroxyethyl cellulose

(3) Qhubeka uvuse kuze kube yilapho zonke izinhlayiya zimanzi

(4) Ukungeza invibitor ye-hlobo, i-pH adjuster, njll.

(5)Govuza kuze kube yonke i-hydroxyethyl celluloseIchitshiyelwa ngokuphelele (i-viscosity yekhambi likhuphuka kakhulu) ngaphambi kokungeza ezinye izinto ekwakhekeni nasekugayeleni kuze kube yilapho kwakhiwa i-lacquer.

2. Ifakwe ngotshwala bamama

Le ndlela ifakwe okokuqala ngotshwala bamama ophakeme bese ingezwe kupende we-latex. Inzuzo yale ndlela ukuthi inokuguquguquka okukhulu futhi kungangezwa ngqo kupende ophelile, kepha kufanele kugcinwe kahle. Izinyathelo nezindlela zifana nezinyathelo (1) - (4) in Methodway 1, ngaphandle kokuthi umgqugquzeli akudingeki ukuthi abe phezulu, futhi kuphela isisulu esinamandla okwanele ukugcina imicu ye-hydroxyethyl ukusatshalaliswa ngokulinganayo kwikhambi liyasetshenziswa . can. Qhubeka uvuse kuze kuncibilike ngokuphelele kwikhambi le-viscous. Kumele kwaziwe ukuthi inhibitor yokubumba kumele ingezwe kuphuzo lotshwala ngokushesha ngokushesha okukhulu.

3. Ngephalishi

Njengoba i-organic solvent iyi-solvent empofu ye-hydroxyethyl cellulose, lezi zinhlaka eziphilayo zingasetshenziswa ukuhlinzeka iphalishi. Izinto ezisetshenziswayo ezisetshenziswa kakhulu ezifana ne-ethylene glycol, i-propenene glycol, kanye ne-heanene noma i-heethane noma i-yiethylene glycol buyl acetate), ngakho-ke amanzi eqhwa avame ukusetshenziswa ndawonye ngoketshezi lwe-organic luhlotshaniswa ne iphalishi. I-porridge-like hydroxyethyl celtulese ingangezwa ngqo kupende. I-Hydroxyyethyl celtulose ifakwe ngokwanele ephalishi. Uma kungezwe kupende, kuyancibilika ngokushesha futhi kube mkhulu. Ngemuva kokungezwa, kuyadingeka ukuqhubeka ngokuvuselela kuze kube yilapho i-hydroxyethyl cellulose ichithwa ngokuphelele futhi i-homogeneous. Ngokuvamile, iphalishi lihlanganiswa nengxenye ye-organic solvent noma amanzi eqhwa kanye nengxenye ye-hydroxyethyl cellulose. Ngemuva kwemizuzu engaba ngu-5 kuye kwengama-30, i-hydroxyethyl cellulose iqhutshwa yi-hydrolyzed futhi kuyamangalisa. Ngokuvamile, umswakama wamanzi ehlobo uphakeme kakhulu futhi akufanele usetshenziselwe iphalishi.

4. Ukuqapha Lapho usebenzisa i-Hydroxyethylllllluloose mama wotshwala

Kusukela i-Hydroxyethyl cellulose (HEC)Ingabe i-granule ephethwe, kulula ukuyiphatha futhi ichithe emanzini inqobo nje uma izindaba ezilandelayo ziphawulwa.

.

(2) Kumele ibonakale kancane ithangiswe ithangi lokuxuba. Ungangezi i-hydroxyethyl celtulose eyenziwe ngebhulokhi kanye nesimo esiyindilinga ngqo ethangini lokuxuba.

(3) Izinga lokushisa lamanzi nenani le-PH emanzini linobudlelwano obukhulu nokuchithwa kwe-hydroxyethyl cellulose, futhi kufanele kuthathwe ukunakekelwa okukhethekile.

(4) Ungangezi ezinye izinto ze-alkaline engxube ngaphambi kwe-hydroxyethyl cellulose powder imakwe ngamanzi. Ukukhuphula i-PH ngemuva kokuthambisa ukusiza ukuncibilikisa.

(5) engeza isikhunta inhibitors ngokushesha okukhulu.
