01.Hydroxyethyl Cellulose
Ua ib qho surfactant uas tsis yog ionic, hydroxyethyl cellulose tsis yog tsuas yog muaj cov haujlwm ntawm kev ncua, thickening, dispersing, flotation, bonding, zaj duab xis-tsim, dej khaws cia thiab muab kev tiv thaiv colloid, tab sis kuj muaj cov khoom hauv qab no:
1. HEC yaj tau hauv dej kub lossis dej txias, thiab tsis ua rau kub dhau lossis kub npau, yog li nws muaj ntau yam solubility thiab viscosity yam ntxwv, thiab tsis yog thermal gelation;
2. Piv nrog rau cov methyl cellulose thiab hydroxypropyl methyl cellulose uas tau lees paub, lub peev xwm ntawm HEC yog qhov phem tshaj plaws, tab sis cov colloid tiv thaiv muaj peev xwm muaj zog tshaj plaws.
3. Lub peev xwm khaws dej tau ob npaug ntawm methyl cellulose, thiab nws muaj kev tswj hwm dej zoo dua.
Cov kev ceev faj thaum siv:
Vim tias hydroxyethyl cellulose uas kho saum npoo yog hmoov lossis cellulose khov, nws yooj yim rau kev tuav thiab yaj hauv dej tsuav yog cov hauv qab no tau sau tseg.
1. Ua ntej thiab tom qab ntxiv hydroxyethyl cellulose, nws yuav tsum tau do tas li kom txog thaum cov tshuaj no pob tshab thiab meej.
2. Yuav tsum tau maj mam lim rau hauv lub thoob sib tov. Tsis txhob ntxiv cov hydroxyethyl cellulose uas tau ua pob lossis pob ncaj qha rau hauv lub thoob sib tov ntau ntau lossis ncaj qha.
3. Qhov kub ntawm dej thiab tus nqi pH ntawm dej muaj kev sib raug zoo nrog kev yaj ntawm hydroxyethyl cellulose, yog li yuav tsum tau saib xyuas tshwj xeeb rau nws.
4. Tsis txhob ntxiv qee yam alkaline rau hauv cov khoom sib tov ua ntejhydroxyethyl celluloseCov hmoov raug dej ua kom sov. Kev tsa tus nqi PH tom qab ua kom sov yog qhov pab tau rau kev yaj.
