Uruhare rwa hydroxyethyl cellulose (HEC) mu gusiga irangi!

Hydroxyethyl cellulose (HEC), ikintu cy’umweru cyangwa umuhondo woroshye, kitagira impumuro, kidahumanya cyangwa gifite ifu, gitegurwa hakoreshejwe uburyo bwo gukwirakwiza cellulose ya alkaline na oxide ya ethylene (cyangwa chlorohydrin), biri mu bwoko bwa ethers za cellulose zishonga za Nonionic. Kubera ko HEC ifite imiterere myiza yo gukurura, guhagarika, gukwirakwiza, gukurura, guhuza, gukora filime, kurinda ubushuhe no gutanga colloids zirinda, yakoreshejwe cyane mu gushakisha amavuta, gusiga irangi, kubaka, imiti n'ibiribwa, imyenda, gukora impapuro na polymer. Polimerization n'ahandi.

Nyuma y'uko hydroxyethyl cellulose ihuye n'irangi rishingiye ku mazi?

Nk'umusemburo utari uwoni, hydroxyethyl cellulose ifite imiterere ikurikira usibye gukomera, guhagarika, gufatanya, kuremba, gukora filime, gukwirakwiza, kubika amazi no gutanga colloids zirinda:

HEC ishongeshwa mu mazi ashyushye cyangwa akonje, kandi ntigwa iyo ubushyuhe bwinshi cyangwa ishyushye, bigatuma igira imiterere itandukanye yo gushonga no gushonga, ndetse no kudashyuha cyane;

Ubushobozi bwo kubika amazi buri kabiri kurusha methyl cellulose, kandi bufite uburyo bwo kugenzura neza amazi;

Ugereranyije na methyl cellulose na hydroxypropyl methyl cellulose byemewe, ubushobozi bwo gutatanya bwa HEC ni bwo bubi cyane, ariko ubushobozi bwo kurinda colloid ni bwo bukomeye cyane;

Ntabwo ari ionic kandi ishobora kubana n'izindi polymer nyinshi zishobora gushonga mu mazi, surfactants, n'umunyu. Ni imashini nziza cyane yo gukurura electrolyte nyinshi.

Ni gute wakoresha hydroxyethyl cellulose?

Ongeraho mu gihe cyo gukora - ubu buryo ni bwo bworoshye kandi butwara igihe gito:

Tangira kuvanga ubudasiba ku muvuduko muto hanyuma ucenge buhoro buhoro hydroxyethyl cellulose neza mu gikoresho hanyuma ukomeze kuvanga kugeza uduce twose twuzuyemo. Hanyuma ongeramo ibintu bibungabunga n'ibindi bikoresho bitandukanye. Nk'amabara, ibikoresho bigabanya ubushyuhe, ammonia, nibindi. Vanga kugeza hydroxyethyl cellulose yose ishongeshejwe burundu (ubushyuhe bw'igikoresho bwiyongera cyane) mbere yo kongeramo ibindi bice muri formula kugira ngo ukore reaction.

Ifite inzoga z'inkorano

Ni ukubanza gutegura inzoga y'umubyeyi ifite ubunini bwinshi, hanyuma ukayishyira ku gicuruzwa. Akamaro k'ubu buryo ni uko ifite ubworoherane bwinshi kandi ishobora kongerwa ku gicuruzwa cyarangiye, ariko igomba kubikwa neza. Intambwe z'ubu buryo zisa n'intambwe nyinshi ziri mu buryo bwa 1; itandukaniro ni uko nta gikoresho cyo gukamura cyane, kandi hari ibikoresho bimwe na bimwe bifite imbaraga zihagije zo kugumana hydroxyethyl cellulose ikwirakwira mu gikoresho kimwe bishobora gukoreshwa, kandi bigakomeza gukangura kugeza ishongeshejwe burundu mu gikoresho cy'umushongi. Ariko, ni ngombwa kumenya ko umuti urwanya udukoko ugomba kongerwa ku nzoga y'umubyeyi vuba bishoboka.

Inama nziza:

Kubera ko hydroxyethyl cellulose ivuwe hejuru ari ifu cyangwa fibre solid, iyo utegura inzoga ya hydroxyethyl cellulose, ibuka kwita ku ngingo zikurikira:

Mbere na nyuma yo kongeramo hydroxyethyl cellulose, igomba gukomeza kuvanga kugeza igihe umuti uboneye neza kandi usobanutse;

Igomba gushyirwa mu mwobo wo kuvanga buhoro buhoro, kandi ntugahuze neza uduce duto cyangwa spheroid na hydroxyethyl cellulose mu mwobo wo kuvanga;

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

Ntugashyiremo ibintu bimwe na bimwe bya alkaline mu ruvange mbere yukoselulose ya hydroxyethylifu inyuzwa mu mazi. Kongera agaciro ka pH nyuma yo kuyivoma bizafasha gushonga;

Uko bishoboka kose, ongeramo umuti urwanya udukoko mbere y'igihe;

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 iragoye kuyifata.
