Uyu munsi, tuzaganira nawe kubijyanye no gukoresha hydroxyethyl selulose mugusiga irangi.Irangi, risanzwe ryitwa impuzu mubushinwa.Ibyo bita igifuniko gitwikiriwe hejuru yikintu kugirango gikingirwe cyangwa gitatse, kandi gishobora gukora firime ikomeza ifatanye neza nikintu kizashyirwaho.
Hydroxyethyl selile ni iki?
Hydroxyethyl selulose (HEC), umuhondo wera cyangwa urumuri rwumuhondo, impumuro nziza, idafite ubumara bwa fibrous cyangwa powdery ikomeye, byateguwe na etherification ya alkaline selulose na oxyde etylene (cyangwa chlorohydrin), ikomoka mubwoko bwa Nonionic soluble selulose ethers.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 nibiribwa, imyenda, gukora impapuro na polymers.Polymerisation hamwe nizindi nzego.
Bigenda bite iyo hydroxyethyl selulose ihuye namaziirangi?
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;
Ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, ubushobozi bwo gukwirakwiza HEC nububi, ariko ubushobozi bwo gukingira colloid nubukomeye;
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.
Nigute ushobora gukoresha hydroxyethyl selile?Nigute ushobora kongeramo?
Ongeraho mugihe cyumusaruro - ubu buryo nuburyo bworoshye kandi bufata igihe gito.
Ongeramo amazi meza kuri vatiri ifite blender-shear ndende.Tangira kubyutsa ubudahwema kumuvuduko muke hanyuma ushungure buhoro buhoro hydroxyethyl selulose neza mubisubizo.Komeza kubyutsa kugeza ibice byose byashizwemo.Noneho ongeramo imiti igabanya ubukana hamwe ninyongera zitandukanye.Nka pigment, imfashanyo zikwirakwiza, amazi ya amoniya, nibindi. Kangura kugeza hydroxyethyl selulose yose imaze gushonga burundu (viscosity yumuti wiyongera cyane) mbere yo kongeramo ibindi bice muri formula kugirango ikore reaction.
Bafite inzoga za nyina.
Nugutegura inzoga ya nyina hamwe nibanze cyane, hanyuma ukayongera kubicuruzwa.Ibyiza byubu buryo nuko bifite ihinduka ryinshi kandi birashobora kwongerwaho kubicuruzwa byarangiye, ariko bigomba kubikwa neza.Intambwe zubu buryo zirasa nintambwe nyinshi muburyo bwa 1;itandukaniro ni uko bidakenewe ubukangurambaga bukabije, kandi gusa bamwe mubakangurambaga bafite imbaraga zihagije zo gukomeza hydroxyethyl selulose ikwirakwizwa kimwe mubisubizo birashobora gukoreshwa, kandi bigakomeza Kuzunguruka kugeza bishonge burundu mubisubizo biboneye.Ariko, tugomba kumenya ko imiti igabanya ubukana igomba kongerwamo inzoga za nyina vuba bishoboka.
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.
