Hydroxyethyl cellulose mu irangi rya emulsion

Uburyo bwo gukoresha hydroxyethyl cellulose mu irangi rya latex

1. Hydroxyethyl cellulosehamwe n'igikoma nk'ikinyabutabire: kubera ko hydroxyethyl cellulose idashonga byoroshye mu bintu bisukura ibikomoka ku bimera, hari ibintu bisukura ibikomoka ku bimera bishobora gukoreshwa mu gushyira igikoma. Amazi y'urubura nayo ni umuti mubi, bityo akunze gukoreshwa mu gikoma hamwe n'ibintu bisukura ibikomoka ku bimera. Hydroxyethyl cellulose yo mu bwoko bwa congee ishobora kongerwamo mu irangi rya emulsii. Hydroxyethyl cellulose yuzuye mu buryo bwa porridge. Iyo yongewe mu irangi, irashonga vuba kandi ikagira ubugari. Komeza uvange kugeza hydroxyethyl cellulose itatanye burundu kandi ishonge. Igikoma gisanzwe gikorwa uvanze ibice bitandatu bya organic solvent cyangwa amazi y'urubura n'igice kimwe cya hydroxyethyl cellulose. Nyuma y'iminota 5-30, hydroxyethyl cellulose irashonga kandi ikazamuka ku buryo bugaragara. (Biravugwa ko ubushuhe bw'amazi mu mpeshyi buba buri hejuru cyane ku buryo budashobora gukoreshwa mu gikoma.)

2. Shyiramo hydroxyethyl cellulose mu ibara ry'umusemburo: ubu buryo ni bworoshye kandi igihe ni gito. Uburyo burambuye ni ubu bukurikira:

(1) Ongeramo amazi meza akwiye ku musozo wa TVA uri hejuru cyane ugomba kugabanya ikintu gitera imvururu (muri rusange, inyongeramusaruro n'ibintu bitose byongerwaho muri iki gihe)

(2) Tangira kuvanga ku muvuduko muto udahagarara hanyuma wongere buhoro buhoro hydroxyethyl cellulose ku buryo bungana

(3) Komeza kuvanga kugeza igihe uduce twose dukwirakwira neza kandi dutose

(4) Ongeramo inhibitor y'imiti hanyuma uhindure agaciro ka PH

(5) Kangura kugeza igihe selulosi ya hydroxyethyl yose ishongeshejwe burundu (ubushyuhe bw'umuti bwiyongera cyane), hanyuma ongeramo ibindi bice muri formula, hanyuma usya kugeza igihe ibaye irangi.

3 hydroxyethyl cellulose hamwe n'amazi meza ategereje: ubu buryo bubanza gushyirwamo amazi menshi y'amazi meza, hanyuma ukongeramo irangi rya latex, inyungu y'ubu buryo ni ukoroshya, bushobora kongeramo ibintu byarangiye mu buryo butaziguye, ariko mu bubiko bukwiye. Intambwe n'uburyo bisa n'intambwe (1) - (4) mu buryo bwa 2, uretse ko ikintu gikamura cyane kidakenewe kandi hari ibintu bimwe na bimwe bifite imbaraga zihagije zo kugumana imigozi ya hydroxyethyl ikwirakwira neza mu gisubizo bikoreshwa. Komeza kuvanga kugeza bishonge neza mu gisubizo gikomeye. Menya ko: umuti urwanya ubwivumbure ugomba kongerwamo vuba bishoboka mu irangi ry'amazi meza.

Ibintu 4 bikenewe kwitabwaho mu gihe cyo gukoresha inzoga ya hydroxyethyl cellulose

Kubera ko hydroxyethyl cellulose ari ifu y’ibinure yavuwe, biroroshye kuyifata no kuyishongesha mu mazi hifashishijwe ingamba zikurikira.

(1) Mbere na nyuma yo kongeramo hydroxyethyl cellulose, ugomba gukomeza kuvanga, kugeza igihe umuti uboneye neza kandi usobanutse.

(2) Ni ngombwa gukurura cellulose ya hydroxyethyl mu gikoresho cyo gukurura buhoro buhoro. Ntuyishyiremo nyinshi cyangwa ngo uyishyire mu gikoresho cyo gukurura.

(3) Uburyo cellulose ya hydroxyethyl ishonga birumvikana ko bifitanye isano n'ubushyuhe bw'amazi n'agaciro ka pH k'amazi, bityo rero ikwiye kwitabwaho cyane.

(4) Ntugashyiremo ibintu by'ibanze mu ruvange mbere yuko ifu ya hydroxyethyl cellulose ishyirwa mu mazi. Kongera pH nyuma yo kuyishyira mu mazi bifasha gushonga.

(5) Uko bishoboka kose, kongeramo hakiri kare uburyo bwo gukumira indwara ya mildew.

(6) Mu gihe ukoresha hydroxyethyl cellulose ifite ubukana bwinshi, igipimo cy'inzoga y'umubyeyi ntigikwiye kurenza 2.5-3% (ukurikije uburemere), bitabaye ibyo inzoga y'umubyeyi iragoye kuyikoresha.

Ibintu bigira ingaruka ku bucucike bw'irangi rya latex:

(1) Bitewe no gukurura cyane no guhumeka cyane iyo bikwirakwira.

(2) ingano y'ibindi bikoresho binini bisanzwe biri mu irangi n'ingano y'ingano irihoselulose ya hydroxyethyl.)

(3) ingano y'ikintu gitera imbaraga ku buso n'amazi mu irangi irangana.

(4 mu gukora latex, ingano ya catalyst oxide isigaye mu mubare.

Isenyuka rya mikorobe mu gice cyo hejuru cy'umubyibuho.

6 mu gikorwa cyo gukora irangi, intambwe zo kongeramo imashini igabanya ubukana zirakwiye.

Uko umwuka usigara mu irangi, niko ubushyuhe burushaho kwiyongera.
