Hydroxyethyl Cellulose (HEC) ni polymer yamazi yamazi ikunze gukoreshwa nkibyimbye, emulisiferi, stabilisateur, nibindi.
Hydroxyethyl Cellulose Intambwe Ziseswa
Tegura ibikoresho n'ibikoresho:
Hydroxyethyl Ifu ya selile
Umuti (ubusanzwe amazi)
Igikoresho gikurura (nka mashini ya stirrer)
Ibikoresho byo gupima (gupima silinderi, kuringaniza, nibindi)
Ibikoresho
Gushyushya umusemburo:
Kugirango byihute inzira yo gusesa, ibishishwa birashobora gushyuha uko bikwiye, ariko muri rusange ntibigomba kurenga 50 ° C kugirango birinde kwangirika kwubushyuhe. Ubushyuhe bwamazi hagati ya 30 ° C na 50 ° C nibyiza.
Buhoro buhoro ongeramo ifu ya HEC:
Buhoro buhoro usukemo ifu ya HEC mumazi ashyushye. Kugira ngo wirinde agglomeration, ongera unyuze mu cyuma cyangwa uyisukeho buhoro. Menya neza ko ifu ya HEC itatanye neza mugihe cyo gukurura.
Komeza kubyutsa:
Mugihe cyo gukurura, komeza wongereho buhoro buhoro ifu ya HEC kugirango urebe ko ifu ikwirakwizwa mumazi. Umuvuduko ukurura ntugomba kwihuta cyane kugirango wirinde ibibyimba na agglomeration. Hagati yo gukurura umuvuduko wo hagati birasabwa.
Iseswa rihagaze: Nyuma yo gutatana byuzuye, mubisanzwe birakenewe guhagarara mugihe runaka (mubisanzwe amasaha menshi cyangwa arenga) kugirango HEC isenyuke burundu kandi igisubizo kimwe. Igihe gihagaze biterwa nuburemere bwa molekuline ya HEC hamwe nubushakashatsi bwibisubizo.
Guhindura ibishishwa: Niba ubukonje bugomba guhinduka, umubare wa HEC urashobora kwiyongera cyangwa kugabanuka muburyo bukwiye. Mubyongeyeho, irashobora kandi guhindurwa wongeyeho electrolytite, guhindura pH agaciro, nibindi.
Kwirinda guseswa
Irinde agglomeration: Hydroxyethyl selulose iroroshye guhuriza hamwe, mugihe rero wongeyeho ifu, witondere byumwihariko kuyinyanyagiza. Icyuma cyangwa ikindi gikoresho gikwirakwiza kirashobora gukoreshwa kugirango gifashe gutatana.
Ubushyuhe bwo kugenzura: Ubushyuhe bwa solde ntibugomba kuba hejuru cyane, bitabaye ibyo birashobora gutera ubushyuhe bwa HEC kandi bikagira ingaruka kumikorere yumuti. Mubisanzwe birakwiriye kubigenzura hagati ya 30 ° C na 50 ° C.
Irinde umwuka kwinjira: Irinde kubyutsa vuba kugirango wirinde umwuka kwinjira mubisubizo kugirango ube ibibyimba. Ibibyimba bizagira ingaruka kuburinganire no gukorera mu mucyo.
Hitamo ibikoresho bikwiye byo gukurura: Hitamo ibikoresho bikwiye bikurura ukurikije ubwiza bwigisubizo. Kubisubizo bito-byoroshye, ibisubizo bisanzwe birashobora gukoreshwa; kubisubizo bihanitse cyane, stirrer irashobora gukenerwa.
Kubika no kubungabunga:
Igisubizo cya HEC cyasheshwe kigomba kubikwa mubintu bifunze kugirango birinde ubushuhe cyangwa umwanda. Iyo ubitswe igihe kirekire, irinde izuba ryinshi nubushyuhe bwo hejuru kugirango umenye neza igisubizo.
Ibibazo rusange nibisubizo
Iseswa ridahwanye:
Niba iseswa ridahwanye, rishobora kuba kubera ko ifu yaminjagiye vuba cyangwa ikabyutsa bidahagije. Igisubizo nukuzamura uburinganire bwikangura, kongera igihe cyo gukurura, cyangwa guhindura umuvuduko wongeyeho ifu mugihe cyo gukurura.
Igisekuru cyinshi:
Niba umubare munini wibibyimba bigaragara mubisubizo, ibituba birashobora kugabanuka mugutinda umuvuduko ukabije cyangwa kureka bigahagarara umwanya muremure. Kubibyimba bimaze kuboneka, imiti itesha agaciro irashobora gukoreshwa cyangwa kuvura ultrasonic birashobora gukoreshwa kubikuraho.
Umuti wibisubizo birakabije cyangwa biri hasi cyane:
Iyo igisubizo cyijimye kitujuje ibisabwa, birashobora kugenzurwa no guhindura umubare wa HEC. Mubyongeyeho, guhindura pH agaciro nimbaraga za ionic igisubizo nacyo gishobora kugira ingaruka kumyumvire.
Urashobora gushonga neza hydroxyethyl selile hanyuma ukabona igisubizo kimwe kandi gihamye. Kumenya neza intambwe ikora nuburyo bwo kwirinda birashobora kugabanya ingaruka za hydroxyethyl selulose mubikorwa bitandukanye.
