Uburyo bwo gukoresha hydroxyethyl selulose mumarangi ya latex

Gukoresha hydroxyethyl selulose mumarangi ya latex nuburyo bukurikira: 1. Ongeraho mugihe usya pigment: ubu buryo buroroshye, kandi igihe cyakoreshejwe ni gito. Intambwe zirambuye nizi zikurikira: (1) ongeramo amazi meza asukuye (mubisanzwe, Ethylene glycol, agent wetting hamwe nuwashizeho firime wongeyeho muriki gihe) (2) tangira kubyutsa umuvuduko muke kandi wongere buhoro buhoro hydroxyethyl selulose (3) komeza kubyutsa kugeza ibice byose bitose (4) ongeramo mildew inhibitor; PH igenzura, nibindi (5) kubyutsa kugeza hydroxyethyl selulose yose yashonze burundu (igisubizo cyubwiyongere bwikibazo) mbere yo kongeramo ibindi bice bigize formula, gusya kugeza irangi.
2.Ibikoresho byinzoga za mama zitegereje gukoreshwa: ubu buryo bwabanje gushyirwamo ingufu nyinshi z’ibinyobwa by’ababyeyi, hanyuma bikongerwaho ku irangi rya latex, ubu buryo bufite inyungu zo guhinduka cyane, bushobora kongerwaho mu buryo butaziguye ku bicuruzwa bisiga amarangi, ariko bigomba kuba bibitswe neza. Intambwe nuburyo bisa nintambwe (1) - (4) muburyo bwa 1, usibye ko umutekamutwe muremure udakenewe, kandi gusa umukangurambaga ufite imbaraga zihagije zo gukomeza fibre hydroxyethyl ikwirakwizwa kimwe mubisubizo. Komeza kubyutsa kugeza bishonge burundu mubisubizo biboneye. Ugomba kumenya ko: mildew inhibitor igomba kongerwamo inzoga za nyina vuba bishoboka. 3. Amashanyarazi akoreshwa cyane nka Ethylene glycol, propylene glycol, hamwe nogukora firime (nka hexanediol cyangwa diethylene glycol butyl acetate), amazi ya barafu nayo adashobora gukemuka, bityo rero akunze gukoreshwa namazi kama kugirango ategure igikoma. Porridge isa na hydroxyethyl selulose irashobora kongerwaho neza kurangi. Hydroxyethyl selulose yuzuye byuzuye muri poroji. Iyo lacquer yongeyeho, ihita ishonga kandi ikabyimba. Nyuma yo kongeramo, bigomba gukangurwa ubudahwema kugeza hydroxyethyl selulose yasheshwe burundu. Mubisanzwe porojora hamwe nibice bitandatu byumuti wamazi cyangwa amazi ya ice hamwe nigice cya hydroxyethyl selulose ivanze, nyuma yiminota 5-30, hydroxyethyl selulose izaba hydrolyz kandi ikabyimba. Impeshyi iyo ubushuhe bwamazi muri rusange buri hejuru cyane, ntibikwiye kubamo ibikoresho bya poroji.
3.Buri. Icyitonderwa mugihe utegura inzoga ya nyina ya hydroxyethyl selulose kuva hydroxyethyl selulose ari agace kavujwe, biroroshye gukora no gushonga mumazi witondera ibi bikurikira. 1 mbere na nyuma yo kongeramo hydroxyethyl selulose, imvange igomba guhora ikomeza kugeza igihe igisubizo kiboneye kandi gisobanutse neza. 2 igomba gushungurwa mu kuvanga ingoma, ntugire umubare munini wibibyimba cyangwa imipira ya hydroxyethyl selulose yongewemo muburyo bwo kuvanga ingoma. 3 solubile ya hydroxyethyl selulose ifitanye isano nubushyuhe bwamazi nagaciro ka pH mumazi, bigomba kwitabwaho byumwihariko. 4 ntukongere ibintu bimwe byingenzi bivanze mbere yuko ifu ya hydroxyethyl selulose yuzura amazi. Kongera pH nyuma yo gushiramo bifasha gushonga. 5 uko bishoboka kwose, hakiri kare kongeramo anti-mildew. 6 iyo ukoresheje hydroxyethyl selulose ya viscosity nyinshi, ibinyobwa bisindisha byababyeyi ntibishobora kuba hejuru ya 2,5-3% (gravimeter), naho ubundi inzoga za nyina ziragoye gukora. Ibintu bigira ingaruka kumyambarire ya latex:
1 Nibyinshi mubirimo umwuka mubi mwirangi, niko kwiyongera. 2 ingano yubushakashatsi bwamazi namazi akoreshwa muburyo bwo gusiga irangi birakwiye. 3 muri synthesis ya latex, ingano ya catalizator isigaye hamwe na oxyde. 4 ingano yubundi bubyibushye busanzwe muburyo bwo gusiga irangi hamwe na hydroxyethyl selulose. 5 mugikorwa cyo gusiga irangi, wongeyeho intambwe ikurikirana ikwiye. 6 kubera ubukana bukabije kuburyo iyo ikwirakwije ubushyuhe bukabije. 7 mikorobe yangirika ya Thickener.
