Nigute ushobora gukoresha Hydroxyethyl selile mu irangi rya latex?

Hydroxyethyl selileikoreshwa cyane mumarangi ya latex, irangi rya emulsion & coatings, nigute wakoresha Hydroxyethyl selulose mumarangi ya latex?

1. Ongeraho muburyo butaziguye

Ubu buryo nuburyo bworoshye kandi bufata igihe gito. Intambwe zirambuye nizi zikurikira:

.

(2) Tangira kubyutsa umuvuduko muke hanyuma wongereho buhoro buhoro hydroxyethyl selile

(3) komeza kubyutsa kugeza ibice byose bitose

(4) Ongeramo mildew inhibitor, pH ihindura, nibindi.

(5)Kangura kugeza hydroxyethyl selile yoseirashonga rwose (viscosity of the solution yiyongereye cyane) mbere yo kongeramo ibindi bice mugutegura no gusya kugeza lacquer ikozwe.

2. ifite ibikoresho byinzoga

Ubu buryo bwabanje gushyirwamo ingufu nyinshi zinzoga za nyina hanyuma zikongerwaho irangi rya latex. Ibyiza byubu buryo nuko bifite ihinduka ryinshi kandi birashobora kongerwaho muburyo butaziguye irangi ryarangiye, ariko bigomba kubikwa neza. Intambwe nuburyo bisa nintambwe (1) - (4) muburyo bwa 1, usibye ko stirrer idasabwa kuba hejuru, kandi gusa stirrer ifite imbaraga zihagije zo gukomeza fibre hydroxyethyl ikwirakwizwa kimwe mugisubizo ikoreshwa. . irashobora. Komeza kubyutsa kugeza bishonge burundu mugisubizo kiboneye. Twabibutsa ko inhibitor ya mold igomba kongerwamo inzoga za nyina vuba bishoboka.

3. hamwe na poroji

Kubera ko ibishishwa kama ari umusemburo muke wa hydroxyethyl selulose, iyi mashanyarazi irashobora gukoreshwa mugutanga igikoma. Umuti ukoreshwa cyane mumashanyarazi nka Ethylene glycol, propylene glycol, hamwe nabakora firime (nka hexane cyangwa diethylene glycol butyl acetate), amazi ya barafu nayo adashobora gukemuka, bityo amazi ya barafu akoreshwa kenshi hamwe namazi ya organic Ifite ibikoresho poroji. Porridge isa na hydroxyethyl selulose irashobora kongerwamo irangi. Hydroxyethyl selulose yashizwemo bihagije muri poroji. Iyo wongeyeho irangi, ihita ishonga kandi ikabyimba. Nyuma yo kongerwaho, birakenewe guhora ubyutsa kugeza hydroxyethyl selulose ishonga burundu kandi bahuje ibitsina. Mubisanzwe, igikoma kivangwa nigice cyamazi kama cyangwa amazi ya ice hamwe nigice cya hydroxyethyl selulose. Nyuma yiminota igera kuri 5 kugeza 30, hydroxyethyl selulose iba hydrolyz kandi ikazamuka kuburyo budasanzwe. Muri rusange, ubuhehere bw’amazi mu cyi ni bwinshi kandi ntibukwiye gukoreshwa kuri poroji.

4. Kwirinda mugihe ukoresheje hydroxyethyl selulose inzoga ya nyina

Kuva hydroxyethyl selulose (HEC)ni granule ivuwe, biroroshye gufata no gushonga mumazi mugihe hagaragaye ibibazo bikurikira.

(1) Mbere na nyuma yo kongeramo hydroxyethylcellulose, kubyutsa bigomba gukomeza kugeza igisubizo kiboneye kandi gisobanutse neza.

(2) Igomba guhindurwa buhoro buhoro mu kigega kivanga. Ntukongere hydroxyethyl selulose yakozwe mubice hamwe nuburyo bwa serefegitura muburyo bwo kuvanga.

(3) Ubushyuhe bwamazi nagaciro ka pH mumazi bifitanye isano ikomeye no gusesa hydroxyethyl selulose, kandi hagomba kwitabwaho bidasanzwe.

. Kongera pH nyuma yo gushiramo bifasha gushonga.

(5) Ongeraho ibibuza kubumba vuba bishoboka.
