Hydroxyethyl selile

Hydroxyethyl selulose (HEC) ni umuhondo wera cyangwa urumuri rwumuhondo, impumuro nziza, fibrous idafite uburozi cyangwa ifu ikomeye yateguwe na etherification ya alkaline selulose na okiside ya Ethylene (cyangwa chlorohydrin). 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. Hydroxyethyl selulose idahindagurika mubushyuhe busanzwe nigitutu, irinda ubushuhe, ubushyuhe, nubushyuhe bwinshi, kandi ifite umunyu mwinshi udasanzwe kuri dielectrics. Igisubizo cyamazi yacyo yemerewe kuba irimo imyunyu myinshi kandi ihamye.

Amabwiriza
Injira muburyo butaziguye

1. Ongeramo amazi meza mu ndobo nini ifite icyuma kinini.

2. Tangira kubyutsa ubudahwema kumuvuduko muke hanyuma ushungure buhoro buhoro hydroxyethyl selulose mubisubizo neza.

3. Komeza kubyutsa kugeza ibice byose byashizwemo.

4. Noneho shyiramo imiti igabanya ubukana, inyongera ya alkaline nka pigment, imiti ikwirakwiza, amazi ya amoniya.

5. Kangura kugeza hydroxyethyl selile yose yasheshwe burundu (viscosity yumuti wiyongera cyane) mbere yo kongeramo ibindi bice muri formula, hanyuma ugasya kugeza ibicuruzwa byarangiye.

Bifite ibikoresho bya alcool

Ubu buryo ni ukubanza gutegura inzoga za nyina zifite imbaraga nyinshi, hanyuma ukayongeramo irangi rya latex. Ibyiza byubu buryo nuko bifite ihinduka ryinshi kandi birashobora kongerwaho muburyo butaziguye irangi ryarangiye, ariko bigomba kubikwa neza. Intambwe zisa nintambwe 1-4 muburyo bwa 1, usibye ko gukurura cyane bidasabwa gushonga burundu mubisubizo biboneye.

Koresha ubwitonzi
Kubera ko hydroxyethyl selile yakozwe hejuru yubutaka ari ifu cyangwa selile ikomeye, biroroshye gufata no gushonga mumazi mugihe hagaragaye ibibazo bikurikira.

1. Mbere na nyuma yo kongeramo hydroxyethyl selulose, igomba guhora ikangurwa kugeza igisubizo kiboneye kandi gisobanutse neza.

2. Igomba gushungurwa mukuvanga gahoro gahoro. Ntukongereho mu buryo butaziguye hydroxyethyl selulose yakozwe mubice cyangwa imipira mukuvanga ingunguru nyinshi cyangwa muburyo butaziguye.

3. Ubushyuhe bwamazi nagaciro ka pH mumazi bifitanye isano ikomeye no gusesa hydroxyethyl selulose, bityo rero tugomba kubyitaho cyane.

4. Ntuzigere wongera ibintu bya alkaline bivanze mbere yuko ifu ya hydroxyethyl selulose ishyushya amazi. Kuzamura agaciro ka PH nyuma yo gushyuha bifasha guseswa.

5. Mugihe gishoboka, ongeramo imiti igabanya ubukana hakiri kare.

6. Iyo ukoresheje hydroxyethyl selulose ifite ubukana bwinshi, ubunini bwinzoga za nyina ntibugomba kuba hejuru ya 2,5-3%, bitabaye ibyo inzoga za nyina ziragoye gukora. Hydroxyethyl selulose nyuma yo kuvurwa mubisanzwe ntabwo byoroshye gukora ibibyimba cyangwa imirima, kandi ntabwo bizakora colloide idashonga nyuma yo kongeramo amazi.
