Ungayisebenzisa kanjani i-hydroxyethyl cellulose ku-latex paint

1. Faka ngqo lapho ugaya upeme: Le ndlela ilula futhi ithathe isikhathi esincane. Izinyathelo ezinemininingwane zimi ngalendlela elandelayo:

.

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

(3) Qhubeka uvuse kuze kube yilapho zonke izinhlayiya zifakwe khona

(4) Ngeza i-antifungal ejenti, i-PH adjuster, njll.

.

2. Lungiselela utshwala bomama ukuze basebenzise: Le ndlela ukulungiselela utshwala bomama onololo oluphakeme kuqala, bese ulufaka ku-latex Paint. Inzuzo yale ndlela ukuthi inokuguquguquka okukhulu futhi kungangezwa ngqo kupende ophelile, kepha kufanele kugcinwe kahle. Izinyathelo nezindlela zifana nezinyathelo (1) - (4) In Methol 1, umehluko ukuthi asikho isidingo se-agaritator ephezulu, futhi kuphela obane-fibers onama-hydroxyethyl strus ahlakazeka ngendlela evumelanayo. Can. Qhubeka ngokuvuselelwa njalo kuze kube kuncibilike ngokuphelele isixazululo se-viscous. Kumele kwaziwe ukuthi i-antifungal ejenti kufanele ingezwe ku-loy youbal mama ngokushesha okukhulu.

I-3. I-Phenology ye-porlidge: Kusukela izixazululo ze-organic zingama-solvents ampofu ze-hydroxyethyl cellulose, lezi zinhlaka eziphilayo zingasetshenziswa ukulungiselela iphalishi. Ama-solvents asetshenziswa kakhulu anjenge-ethylene glycol, i-plylene glycol, kanye ne-hexylene ejenti (njenge-hexylene glycol noma i-diethylene glycol i-solvent futhi i-solvent empofu, ngakho-ke amanzi eqhwa avame ukusetshenziswa ndawonye ngoketshezi lwe-organic. Ukulungiselela iphalishi.

I-porridge-like hydroxyethyl celtulese ingangezwa ngqo kupende. I-hydroxyethyl cellulose ibivuvukale ngokuphelele ephalisheni. Uma ungezwe kupende, masinyane uyancibilika futhi uqweqwe. Ngemuva kokungeza, kumele kushukunyiswe ngokuqhubekayo kuze kube yilapho i-hydroxyethyl cellulose ichithwa ngokuphelele futhi iyunifomu. Ngokuvamile, iphalishi lihlanganiswa nezingxenye eziyisithupha ze-organic solvent noma amanzi eqhwa nengxenye eyodwa ye-hydroxyethyl cellulose. Ngemuva kwemizuzu engaba ngu-5-30, i-hydroxyethyl cellulose izobe i-hydrolyzed futhi ivuvukale kusobala. Ehlobo, umswakama wamanzi ajwayelekile uphezulu kakhulu, futhi akufanelekile ukusetshenziselwa iphalishi.

4. Izindaba ezidinga ukunakwa lapho zilungiselela i-hydroxyethyyl cellulose makeome yotshwala

Njengoba i-hydroxyethyl cellulose iyimpuphu ecubunguliwe, kulula ukuyiphatha futhi ichithe emanzini inqobo nje uma izindaba ezilandelayo ziphawulwa.

1) Ngaphambi nangemva kokungeza i-hydroxyethyl cellulose, kuyadingeka ukuthi uqhubeke uvuselelwa kuze kube yilapho isixazululo sisobala futhi sicacile.

2) Kufanele ibonakale emgqonyeni wokuxuba kancane, futhi ungangezi i-hydroxyethyl cellulose eyenziwe izigaxa noma amabhola ngqo emgqonyeni wokuxuba.

3) Izinga lokushisa lamanzi nenani le-PH emanzini linobudlelwano obukhulu nokuchithwa kwe-hydroxyethyl cellulose, ngakho-ke kufanele kukhokhwe kuwo.

4) Ungangezi ezinye izinto ze-alkali ngayinye engxube ngaphambi kwe-hydroxyethyl cellulose powder ifakwe emanzini. Ukuphakamisa i-PH kuphela ngemuva kokumanzisa kuzosiza ekuqothulweni.

5) ngangokunokwenzeka, engeza i-antifungal ejenti kusenesikhathi.

6) Uma usebenzisa i-High-VisloxyYyl cellulose, ukugcwaliswa kotshwala mama akufanele kube ngaphezulu kuka-2,5-3% (ngesisindo), uma kungenjalo, lophuzo lomama kuzoba nzima ukuphatha.
