Guhura hagati ya hydroxyethyl selulose hamwe namazi ashingiye kumazi

Hydroxyethyl Cellulose ni iki?
Hydroxyethyl selulose (HEC), umuhondo wera cyangwa urumuri rwumuhondo, impumuro nziza, fibrous idafite uburozi cyangwa ifu ikomeye, yateguwe na etherification reaction ya alkaline selulose na Ethylene oxyde (cyangwa chlorohydrin), ni iyitwa etion ya solionose.Kubera ko HEC ifite ibyiza byo kubyimba, guhagarika, gutatanya, kwigana, guhuza, gukora firime, kurinda ubushuhe no gutanga colloide ikingira, yakoreshejwe cyane mubushakashatsi bwamavuta, gutwikira, kubaka, ubuvuzi, ibiryo, imyenda, gukora impapuro na polymer Polymerisation n'indi mirima.

Hydroxyethyl selulose ikoreshwa cyane mubikorwa byo gutwikira, reka turebe uko ikora mubitambaro:

Bigenda bite iyo hydroxyethyl selulose ihuye n'irangi rishingiye kumazi?

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

HEC irashonga mumazi ashyushye cyangwa mumazi akonje, ubushyuhe bwinshi cyangwa guteka nta mvura igwa, kuburyo ifite uburyo bwinshi bwo kwikemurira no kuranga ibishishwa, hamwe nubushuhe butari ubushyuhe;

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

Ntabwo ari ionic kandi irashobora kubana hamwe nandi moko menshi yandi mazi ashonga polymers, surfactants, nu munyu.Nibyimbye byiza bya colloidal kubyibushye cyane bya electrolyte ibisubizo;

Ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, ubushobozi bwo gukwirakwiza HEC nububi, ariko ubushobozi bwo gukingira colloid nabwo bukomeye.

Kubera ko hydroxyethyl selile yakozwe hejuru yubutaka ari ifu cyangwa fibrous ikomeye, ingingo zikurikira zigomba gukurikizwa mugihe utegura inzoga ya hydroxyethyl selulose:

(1) Mbere na nyuma yo kongeramo hydroxyethyl selulose, igomba guhora ikomeza kugeza igihe igisubizo kiboneye kandi gisobanutse neza.

.Kuzamura pH nyuma yo guhanagura bifasha gushonga.
(5) Mugihe gishoboka, ongeramo antifungal hakiri kare.
