Hydroxyethyl selile ni iki?

Hydroxyethyl selulose (HEC) ni umuhondo wera cyangwa umuhondo wera, utagira impumuro nziza, fibrous idafite uburozi cyangwa ifu ikomeye, byateguwe na etherification reaction ya alkaline selulose na okiside ya etilene (cyangwa chlorohydrin).
1.Amabwiriza
1.1 wongeyeho mugihe cyumusaruro

1. Ongeramo amazi meza mu ndobo nini ifite imashini ivanze cyane.

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

3. Komeza kubyutsa kugeza ibice byose byashizwemo.

4. Noneho ongeramo imiti igabanya ubukana, inyongeramusaruro 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.

1.2 Byateguwe n'inzoga za nyina

Ubu buryo nugutegura inzoga za mama hamwe nibanze cyane, 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, itandukaniro nuko nta mpamvu yo gukanguka kugeza igihe izashonga burundu mugisubizo kiboneye.

2.Porridge ya fenologiya
Kubera ko ibishishwa kama ari ibishishwa bikennye kurihydroxyethyl selile, ibishishwa kama birashobora gukoreshwa mugutegura igikoma. Imiti ikoreshwa cyane ni ibinyabuzima byamazi nka Ethylene glycol, propylene glycol hamwe nabakora firime (nka Ethylene glycol cyangwa diethylene glycol butyl acetate) muburyo bwo gusiga amarangi. Amazi yo mu rubura nayo adashobora gukemuka, bityo amazi ya barafu akoreshwa kenshi hamwe namazi kama kugirango bategure igikoma. Hydroxyethyl selulose ya poroji irashobora kongerwaho muburyo butaziguye, kandi hydroxyethyl selulose yagabanijwe ikabyimba muri poroji. Iyo wongeyeho irangi, irahita ishonga kandi ikora nkibyimbye. Nyuma yo kongeramo, komeza ubyuke kugeza hydroxyethyl selulose imaze gushonga kandi imwe. Mubisanzwe, poroji ikorwa mukuvanga ibice bitandatu byumusemburo wamazi cyangwa urubura nigice kimwe cya hydroxyethyl selulose. Nyuma yiminota igera kuri 6-30, hydroxyethyl selulose izaba hydrolyz kandi ikabyimba bigaragara. Mu ci, ubusanzwe amazi yubushyuhe buri hejuru cyane, ntabwo rero akwiriye gukoresha poroji.
3.Umwanya wo gusaba

Hydroxyethyl selulose Yifashishijwe nkibifata, surfactants, imiti ikingira imiti, ikwirakwiza, nibindi.
Ifite uburyo butandukanye bwo gukoresha amarangi, irangi, fibre, irangi, gukora impapuro, kwisiga, imiti yica udukoko, gutunganya amabuye y'agaciro, imiti igarura amavuta, hamwe nubuvuzi.

1. matrix-ubwoko burambye-burekura imyiteguro, kandi irashobora no gukoreshwa nka stabilisateur mubiryo.

2.

3. Ikoreshwa nkigabanya umubyibuho ukabije nogutakaza amazi kumazi ashingiye kumazi no gutembera kwamazi, kandi ingaruka zo kubyimba zigaragara mumazi yo gucukura. Irashobora kandi gukoreshwa nkigabanuka ryamazi yo kugabanya amavuta ya sima. Irashobora guhuzwa hamwe nicyuma cya polyvalent ion kugirango ikore gel.

4. Irashobora kandi gukoreshwa nkibyimbye bya emuliyoni mu nganda zisiga amarangi, hygrostat mu nganda za elegitoroniki, antimaagulant ya sima hamwe n’umukozi ushinzwe kubika amazi mu nganda zubaka. Inganda zububumbyi zirabagirana hamwe nuguhuza amenyo. Ikoreshwa kandi cyane mu gucapa no gusiga irangi, imyenda, gukora impapuro, imiti, isuku, ibiryo, itabi, imiti yica udukoko hamwe n’ibikoresho bizimya umuriro.

5. Nka surfactant, agent irinda colloidal, stabilisateur ya emulisifike ya vinyl chloride, vinyl acetate nizindi emulisiyo, hamwe na latx tackifier, dispersant, stabilisateur ikwirakwiza, nibindi bikoreshwa cyane mubitambaro, fibre, irangi, gukora impapuro, kwisiga, imiti, imiti yica udukoko. , nibindi Ifite kandi byinshi mubushakashatsi bwamavuta ninganda zimashini.

6.

7. Ikoreshwa nka polymeric ikwirakwiza mugukoresha peteroli ikomoka kumavuta ya peteroli yamenetse, polyvinyl chloride na polystirene. Irashobora kandi gukoreshwa nkibyimbye bya emuliyoni mu nganda zisiga amarangi, imiti igabanya ubukana bwa sima hamwe n’ibikoresho bigumana amazi mu nganda z’ubwubatsi, umukozi wo kumena amarangi hamwe n’amenyo yangiza amenyo mu nganda z’ubutaka. Ikoreshwa kandi cyane mubikorwa byinganda nko gucapa no gusiga irangi, imyenda, gukora impapuro, ubuvuzi, isuku, ibiryo, itabi nudukoko.
