Uburyo bwo gukoresha hydroxyethyl cellulose mu irangi rya latex
1. Hydroxyethyl cellulose ikoreshwa mu gukora igikoma: Kubera ko hydroxyethyl cellulose idashongesha mu bintu bidafite umwimerere, hari ibintu bimwe na bimwe bishobora gukoreshwa mu gutegura igikoma. Amazi y'urubura nayo ni umuti mubi, bityo amazi y'urubura akunze gukoreshwa hamwe n'ibintu bidafite umwimerere mu gutegura igikoma. Hydroxyethyl cellulose isa n'ifu ishobora kongerwamo irangi rya latex. Hydroxyethyl cellulose yamaze gushyirwa mu gikoma. Iyo yongewemo irangi, irashonga vuba kandi igakora nk'iy'ingufu. Nyuma yo kongeramo, komeza uvange kugeza igihe hydroxyethyl cellulose itatanye burundu kandi ishongeshejwe. Muri rusange, igikoma gikorwa uvanze ibice bitandatu bya hydroxyethyl cellulose cyangwa amazi y'urubura n'igice kimwe cya hydroxyethyl cellulose. Nyuma y'iminota 5-30, hydroxyethyl cellulose izavangwa na hydrolyze kandi ibyimbe neza. (Wibuke ko ubushuhe bw'amazi rusange buba bwinshi cyane mu mpeshyi, bityo ntabwo bugomba gukoreshwa mu gushyira igikoma.)
2. Shyiramo hydroxyethyl cellulose mu buryo butaziguye mugihe usya irangi: Ubu buryo bworoshye kandi bufata igihe gito. Uburyo burambuye ni ubu bukurikira:
(1) Shyiramo amazi meza akwiye mu ndobo nini y'icyuma gishyushya cyane (muri rusange, ibikoresho bifasha mu gukora filime n'ibintu bitose byongerwamo muri iki gihe)
(2) Tangira kuvanga ubudasiba ku muvuduko muto hanyuma buhoro buhoro kandi ku buryo bungana wongeremo hydroxyethyl cellulose
(3) Komeza kuvanga kugeza igihe uduce twose dukwirakwira neza kandi dutose
(4) Shyiramo inyongera zirwanya ubwivumbure kugira ngo 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 irangi ribereye.
3. Tegura hydroxyethyl cellulose hamwe n'inzoga y'umubyeyi kugira ngo ikoreshwe nyuma: Ubu buryo ni ugutegura inzoga y'umubyeyi ifite ubunini bwinshi, hanyuma ukayishyira mu irangi rya latex. Akamaro k'ubu buryo ni uko yoroshye kandi ishobora kongerwamo irangi rirangiye, ariko igomba kubikwa neza. Intambwe n'uburyo bisa n'intambwe (1)-(4) mu buryo bwa 2, itandukaniro ni uko nta kintu gitera imbaraga nyinshi gikenewe, kandi hari ibintu bimwe na bimwe bitera imbaraga bihagije kugira ngo fibre ya hydroxyethyl igumane neza mu gisubizo ni Can. Komeza ubyuke ubudasiba kugeza bishongeshejwe burundu mu gisubizo cy'umusazi. Ni ngombwa kumenya ko umuti urwanya udukoko ugomba kongerwa mu irangi ry'umubyeyi vuba bishoboka.
Ibintu 4 bikenewe kwitabwaho mu gutegura inzoga ya hydroxyethyl cellulose
Kubera ko hydroxyethyl cellulose ari ifu itunganywa, biroroshye kuyifata no kuyishongesha mu mazi igihe cyose ibintu bikurikira byitabwaho.
(1) Mbere na nyuma yo kongeramo hydroxyethyl cellulose, igomba kuvangwa buri gihe kugeza igihe umuti uboneye neza kandi usobanutse.
(2) Igomba gushungurwa buhoro buhoro mu mvange, kandi ntushyiremo hydroxyethyl cellulose nyinshi yakozwemo uduce cyangwa utubumbe mu mvange.
(3) Ubushyuhe bw'amazi n'agaciro ka pH mu mazi bifitanye isano rikomeye n'ishonga rya hydroxyethyl cellulose, bityo hagomba kwitabwaho cyane.
(4) Ntugashyiremo ibintu bya alkaline mu ruvange mbere yuko ifu ya hydroxyethyl cellulose itoswa n'amazi. Kongera pH nyuma yo gutosa bifasha gushonga.
(5) Uko bishoboka kose, ongeramo imiti irwanya imiyoboro hakiri kare.
(6) Mu gihe ukoresha hydroxyethyl cellulose ifite ubukana bwinshi, igipimo cy'inzoga y'umubyeyi ntikigomba kurenza 2.5-3% (ukurikije uburemere), bitabaye ibyo inzoga y'umubyeyi izagorana kuyifata.
Ibintu bigira ingaruka ku bucucike bw'irangi rya latex:
(1) Bitewe no gukaraba cyane, ubushuhe bushyuha cyane mu gihe cyo gukwirakwira kw'amazi.
(2) Ingano y'ibindi bintu bigabanya ubukana bw'irangi mu irangi n'ikigereranyo cy'ingano ya hydroxyethyl cellulose.
(3) Niba ingano ya surfactant n'ingano y'amazi yakoreshejwe muri formula y'irangi bikwiye.
(4) Mu gukora latex, ingano y'ibikubiye muri okiside nk'ibisigaye bya catalyst.
(5) Kwangirika kw'ikintu gikomeza ubushyuhe giterwa na mikorobe.
(6) Mu gikorwa cyo gukora irangi, niba intambwe yo kongeramo imashini igabanya ubukana ikwiye.
7 Uko umwuka urushaho kuba mwinshi mu irangi, ni ko ubushyuhe burushaho kwiyongera
