Hydroxyethyl selile ni iki?

Hydroxyethyl selulose (HEC), umuhondo wera cyangwa wijimye, udafite impumuro nziza, fibrous idafite uburozi cyangwa ifu ikomeye, byateguwe na etherification ya alkaline selulose na okiside ya Ethylene (cyangwa chlorohydrin), ikomoka mubwoko bwa Nonionic soluble selulose ethers. Kubera ko HEC ifite ibintu byiza nko kubyimba, guhagarika, gutatanya, kwigana, guhuza, gukora firime, kurinda ubushuhe no gutanga colloide ikingira, yakoreshejwe cyane mubushakashatsi bwamavuta, gutwikira, kubaka, ubuvuzi nibiribwa, imyenda, gukora impapuro na polymers. Polymerisation hamwe nizindi nzego.

Hydroxyethyl selulose ikoreshwa cyane mubikorwa byo gutwikira. Reka turebe uko ikora mubitambaro:

Bigenda bite iyo hydroxyethyl selulose ihuye n'amazi ashingiye kumazi?

Nka surfactant idafite ionic, hydroxyethyl selulose ifite imitungo ikurikira usibye kubyimba, guhagarika, guhambira, flotation, gukora firime, gutatanya, kubika amazi no gutanga colloide ikingira:

HEC irashobora gushonga mumazi ashyushye cyangwa akonje, kandi ntigwa kugwa mubushyuhe bwinshi cyangwa kubira, bigatuma igira ibintu byinshi byo gushonga no kuranga ibibyimba, kimwe no guterwa n'ubushyuhe;

Ubushobozi bwo gufata amazi bwikubye kabiri ubwa methyl selulose, kandi bufite gahunda nziza yo gutembera;

Non-ionic ubwayo irashobora kubana hamwe nandi moko menshi yandi mazi ashonga polymers, surfactants, nu munyu, kandi ni umubyimba mwiza wa colloidal urimo ibisubizo byinshi bya electrolyte;

Ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, ubushobozi bwo gukwirakwizaHECni bibi cyane, ariko ubushobozi bwo kurinda colloid nubushobozi bukomeye.

Kubera ko hydroxyethyl selile yakozwe hejuru yubutaka ari ifu cyangwa fibrous ikomeye, Shandong Heda arakwibutsa kwitondera ingingo zikurikira mugihe utegura inzoga ya hydroxyethyl selulose:

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

. Kuzamura pH nyuma yo guhanagura bizafasha mu gusesa.

(5) Mugihe gishoboka, ongeramo imiti igabanya ubukana mbere.
