Hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) ni umweru cyangwa umuhondo woroshye, nta mpumuro, idahumanya, idahumanya cyangwa ifu ikomeye yateguwe binyuze mu gushonga kwa alkaline cellulose na ethylene oxide (cyangwa chlorohydrin). Nonionic soluble cellulose ethers. Kubera ko HEC ifite imiterere myiza yo gukomera, guhagarika, gukwirakwiza, gushonga, guhuza, gukora filime, kurinda ubushuhe no gutanga colloids zirinda, yakoreshejwe cyane mu gushakisha amavuta, gusiga, kubaka, imiti n'ibiribwa, imyenda, gukora impapuro na polymers. Polymerization n'indi mirima. Hydroxyethyl cellulose ntihindagurika ku bushyuhe busanzwe n'umuvuduko, yirinda ubushuhe, ubushyuhe, n'ubushyuhe bwinshi, kandi ifite umunyu mwiza cyane ushonga kuri dielectrics. Umuti wayo w'amazi wemerewe kuba ufite umunyu mwinshi kandi uhoraho.

Amabwiriza
Injira mu buryo butaziguye mu gutunganya

1. Shyiramo amazi meza mu ndobo nini ifite icyuma gikoresha ikoranabuhanga ryo gukamura amazi.

2. Tangira kuvanga ubudasiba ku muvuduko muto hanyuma ucenge buhoro buhoro hydroxyethyl cellulose mu gisubizo kimwe.

3. Komeza kuvanga kugeza igihe uduce twose twuzuyemo.

4. Hanyuma ongeramo imiti yica udukoko, ibintu bivanze n'amazi nk'ibirangi, ibikoresho bigabanya ubushyuhe, amazi ya amoniya.

5. Kangura kugeza igihe selulosi ya hydroxyethyl yose ishongeshejwe burundu (ubushyuhe bw'umuti bwiyongera cyane) mbere yo kongeramo ibindi bice muri formula, hanyuma usya kugeza igihe birangiye.

Ifite inzoga z'inkorano

Ubu buryo ni ukubanza gutegura inzoga y'umubyeyi ifite ubunini bwinshi, hanyuma ukayishyira mu irangi rya latex. Akamaro k'ubu buryo ni uko ifite ubworoherane bwinshi kandi ishobora kongerwamo irangi rirangiye, ariko rigomba kubikwa neza. Intambwe zisa n'intambwe ya 1-4 mu buryo bwa 1, uretse ko kuvanga cyane bidakenewe kugira ngo bishonge neza mu buryo buvanze n'amazi.

Koresha ubwitonzi
Kubera ko hydroxyethyl cellulose yavuwe ku buso ari ifu cyangwa selulose ikomeye, biroroshye kuyifata no kuyishongesha mu mazi igihe cyose hagaragajwe ibi bikurikira.

1. Mbere na nyuma yo kongeramo hydroxyethyl cellulose, igomba guhora ivangwa kugeza igihe umuti uboneye neza kandi usobanutse.

2. Igomba gushyirwa mu mwobo wo kuvanga buhoro buhoro. Ntugashyiremo selulose ya hydroxyethyl yakozwe mu tubumbe cyangwa utubumbe twinshi mu mwobo wo kuvanga ku bwinshi cyangwa ku buryo butaziguye.

3. Ubushyuhe bw'amazi n'agaciro ka pH by'amazi bifitanye isano rikomeye n'ishonga rya hydroxyethyl cellulose, bityo rero bigomba kwitabwaho cyane.

4. Ntuzigere wongeramo ibintu bimwe na bimwe bya alkaline mu ruvange mbere yuko ifu ya hydroxyethyl cellulose ishyushywa n'amazi. Kongera agaciro ka PH nyuma yo gushyuha ni ingirakamaro mu gushonga.

5. Uko bishoboka kose, ongeramo umuti urwanya udukoko hakiri kare.

6. Mu gihe ukoresha hydroxyethyl cellulose ifite ubukana bwinshi, ingano y'inzoga y'umubyeyi ntigomba kurenza 2.5-3%, bitabaye ibyo inzoga y'umubyeyi iragoye kuyikoresha. Inzoga y'umubyeyi ...
