Uruhare nogukoresha latex irangi hydroxyethyl selulose

Nigute wakoresha hydroxyethyl selulose mumarangi ya latex

1. Hydroxyethyl selulose ikoreshwa mugutegura poroji: Kubera ko hydroxyethyl selulose itoroshye gushonga mumashanyarazi kama, imiti imwe nimwe irashobora gukoreshwa mugutegura igikoma.Amazi ya barafu nayo adashobora gukemuka, kubwibyo amazi yurubura akoreshwa hamwe namazi kama kugirango ategure igikoma.Porridge isa na hydroxyethyl selulose irashobora kongerwaho muburyo butaziguye irangi rya latex.Hydroxyethyl selulose yarabyimbye rwose muri poroji.Iyo wongeyeho irangi, irashonga vuba kandi igira uruhare runini.Nyuma yo kongeramo, biracyakenewe gukomeza kubyutsa kugeza hydroxyethyl selulose ikwirakwijwe burundu.Mubisanzwe, igikoma kivanze nibice bitandatu byumusemburo wamazi cyangwa urubura nigice kimwe cya hydroxyethyl selulose.Nyuma yiminota 5-30, hydroxyethyl selulose izahinduka hydrolyz kandi ikabyimba bigaragara.(Bavuga ko ubuhehere bw’amazi rusange ari menshi cyane mu cyi, bityo ntibikwiye gukoreshwa kuri porojora.)

2. Ongeramo hydroxyethyl selulose mugihe usya pigment: Ubu buryo buroroshye kandi bufata igihe gito.Uburyo burambuye nuburyo bukurikira:

.

:

(3) Komeza kubyutsa kugeza ibice byose bitatanye neza kandi byuzuye

(4) Ongeraho inyongeramusaruro kugirango uhindure agaciro ka PH

.

3. Tegura hydroxyethyl selulose hamwe n'inzoga za nyina kugirango ukoreshwe: Ubu buryo nugutegura inzoga za nyina zifite intumbero nyinshi, hanyuma ukayongeramo irangi rya latex.Ibyiza byubu buryo nuko byoroshye kandi bishobora kongerwaho bitaziguye irangi ryarangiye, ariko bigomba kubikwa neza..Intambwe nuburyo bisa nintambwe (1) - (4) muburyo bwa 2, itandukaniro nuko ntagikenewe agiteri-yogosha cyane, kandi gusa bamwe mubakangurambaga bafite imbaraga zihagije kugirango fibre hydroxyethyl itatanye kimwe muri igisubizo kirakoreshwa.Birashoboka.Komeza guhora ukurura kugeza ushonge burundu mugisubizo kiboneye.Twabibutsa ko imiti igabanya ubukana igomba kongerwamo inzoga ya nyina irangi vuba bishoboka.

4 Ibintu bikeneye kwitabwaho mugihe utegura inzoga ya hydroxyethyl selulose

Kubera ko hydroxyethyl selulose ari ifu yatunganijwe, biroroshye gufata no gushonga mumazi mugihe hagaragaye ibibazo bikurikira.

(1) Mbere na nyuma yo kongeramo hydroxyethyl selulose, bigomba guhora bikurura kugeza igisubizo kiboneye kandi gisobanutse neza.

(2) Igomba gushungurwa mukuvanga gahoro gahoro.Ntukongereho hydroxyethyl selulose yakozwe mubice no mumipira mukuvanga ingunguru nyinshi cyangwa muburyo butaziguye.

.Kuzamura pH nyuma yo guhanagura bizafasha mu gusesa.

(5) Mugihe gishoboka, ongeramo imiti igabanya ubukana hakiri kare.

.

Ibintu bigira ingaruka kumyambarire ya latex:

(1) Ubushuhe burashyuha mugihe cyo gutatana kubera gukurura cyane.

.)

(3) Niba ingano ya surfactant nubunini bwamazi muri formula irangi birakwiye.

(4 Iyo ushushanya latex, ingano ya catalizator isigaye hamwe na oxyde.

Isuri ya mikorobe yibyibushye.

6 Mugihe cyo gukora amarangi, urutonde rwintambwe zo kongeramo umubyimba birakwiye?

7 Iyo ibintu byinshi biri mu kirere bisigaye mu irangi, niko ubwiza bwiyongera
