Hydroxyethyl selulose (HEC), umuhondo wera cyangwa urumuri rwumuhondo, impumuro nziza, idafite ubumara bwa fibrous cyangwa powdery ikomeye, yateguwe na etherification reaction ya alkaline selulose na okiside ya Ethylene (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.
Nyuma yinama ya hydroxyethyl selulose hamwe 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;
Ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, ubushobozi bwo gukwirakwiza HEC nububi, ariko ubushobozi bwo gukingira colloid nabwo bukomeye;
Ntabwo ari ionic kandi irashobora kubana hamwe nandi moko menshi yandi mazi ashonga polymers, surfactants, nu munyu. Nibyiza cyane bya colloidal kubyibisubizo birimo electrolytite yibanda cyane.
Nigute ushobora gukoresha hydroxyethyl selile?
Ongeraho mugihe cyumusaruro - ubu buryo nuburyo bworoshye kandi bufata igihe gito:
Tangira kubyutsa ubudahwema kumuvuduko muke hanyuma ushungure buhoro buhoro hydroxyethyl selulose iringaniye mubisubizo hanyuma ukomeze kubyutsa kugeza ibice byose byashizwemo. Noneho ongeramo imiti igabanya ubukana hamwe ninyongera zitandukanye. Nka pigment, imfashanyo ikwirakwiza, amazi ya amoniya, nibindi. Kangura kugeza hydroxyethyl selulose yose imaze gushonga burundu (viscosity yumuti wiyongera cyane) mbere yo kongeramo ibindi bice muburyo bwo kubyitwaramo.
Bafite inzoga za nyina
Nugutegura inzoga za nyina ubanza kwibanda cyane, hanyuma ukongeraho 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 nta mpamvu yo gukenera cyane, kandi bamwe mubakangurambaga bafite imbaraga zihagije zo gukomeza hydroxyethyl selulose ikwirakwizwa kimwe mubisubizo birashobora gukomeza nta guhagarika Stir kugeza bishonge burundu mubisubizo biboneye. Icyakora, tugomba kumenya ko fungiside igomba kongerwamo inzoga za nyina vuba bishoboka.
Inama nziza:
Kubera ko hydroxyethyl selile yakozwe hejuru yubutaka ari ifu cyangwa fibrous ikomeye, mugihe utegura inzoga ya hydroxyethyl selulose, wibutsa kwitondera ingingo zikurikira:
Mbere na nyuma yo kongeramo hydroxyethyl selulose, igomba guhora ikomeza kugeza igisubizo kiboneye kandi gisobanutse;
Igomba gushungura buhoro buhoro mu kigega kivanze, kandi ntugashyire mu buryo butaziguye mu kigega kivanga ku bwinshi cyangwa mu bibyimba, imipira na selile ya hydroxyethyl;
Ubushyuhe bwamazi nagaciro ka PH mumazi bifitanye isano igaragara no gusesa hydroxyethyl selile, bityo rero hagomba kwitabwaho byumwihariko;
Ntugashyiremo ibintu bimwe na bimwe bya alkaline bivanze mbere yuko ifu ya hydroxyethyl selulose yinjizwa namazi. Kuzamura agaciro ka pH nyuma yo gushiramo bizafasha gushonga;
Ibishoboka byose, ongeramo anti-mold hakiri kare;
Iyo ukoresheje hydroxyethyl selulose-yuzuye cyane, ubunini bwinzoga za nyina ntibugomba kuba hejuru ya 2,5-3% (kuburemere), bitabaye ibyo inzoga za nyina zizagorana kubyitwaramo.
