2. Horumarinta waxqabadka ikhtiyaariga ah
Cellulose ether HE taxane, taas oo ah, hydroxyethyl cellulose, waa caddaan ilaa caano budo ah. Waxaa lagu milmi karaa labadaba biyo kulul iyo biyo qabow, laakiin ma fududa in lagu milmo dareerayaasha organic. Jinshi summada cellulose ether HE alaabada taxanaha ah waxay leeyihiin haynta biyaha oo xoog leh, samaynta filim, iska caabin milix ah iyo saamaynta dhumucda. Waxa kale oo ay leedahay waafaqid midab aad u fiican waana wax lagu daro ku habboon codsiyada latex.
Hydroxyethyl cellulose HEC waa dhumuc caadi ahaan loo isticmaalo daaha waxayna leedahay faa'iidooyinka soo socda:
(1) Kala duwanaansho xoog leh Hydroxyethyl cellulose HEC waa polymer aan-ionic-biyo-milmi leh oo loo isticmaali karo pH ballaaran (2-12). Waxaa lagu qasi karaa qaybaha dahaarka guud (sida midabada, waxyaabaha lagu daro, cusbada milmay iyo electrolytes) iyada oo aan lahayn ifafaale aan caadi ahayn. ah
(2) Dhisme wanaagsan. Dahaarka ku dhumucdiisuna waxay leedahay hydroxyethyl cellulose HEC waxay leedahay pseudoplasticity, sidaas darteed waxaa lagu dabaqi karaa cadayashada, buufinta, dahaarka rullaluistemadka iyo hababka kale ee dhismaha. Faa'iidooyinka, sinnaanta ayaa sidoo kale ka fiican. ah
(3) Ma jiraan wax saameyn xun ku leh filimka daahan. Sababo la xiriira sifooyinka kacsanaanta dusha biyaha ee aan muuqan ee xalka aqueous HEC, ma fududa in la xumbo inta lagu jiro dhismaha iyo wax soo saarka, waxaana yar u janjeera in la soo saaro godadka volcano iyo godad. ah
(4) Kobcinta midabka wanaagsan. Hydroxyethyl cellulose HEC waxay leedahay miscibility aad u fiican oo leh inta badan xirmooyinka iyo midabada, si rinjiga diyaarsan uu u yeesho xasillooni midab wanaagsan iyo joogtayn.
(5) Xasilooni kaydinta wanaagsan. Inta lagu jiro kaydinta rinjiga, waxay ilaalin kartaa joojinta iyo kala-baxa midabka midabka, iyada oo aan dhibaatooyinka sabbaynaya iyo ubaxa. Waxaa jira lakabka biyaha ee dusha sare ee rinjiga. Marka heerkulku kaydiyo is beddelo, viscosity-kiisu sidiisii ayuu ahaanayaa. xasiloon badan.
