Hydroxyethyl selulose (HEC) ni umuhondo wera cyangwa urumuri rwumuhondo, impumuro nziza, fibrous idafite uburozi cyangwa ifu ikomeye, itegurwa na etherification reaction 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, ibiryo, imyenda, gukora impapuro na polymer Polymerisation n'indi mirima. Igipimo cya mesh 40 mesh 99%;
Kugaragara: cyera kugeza cyoroheje fibrous yumuhondo cyangwa ifu ikomeye, idafite uburozi, uburyohe, gushonga mumazi. Kudashonga mumashanyarazi asanzwe.
Ubukonje burahinduka gato murwego rwa PH agaciro 2-12, ariko ububobere bugabanuka kurenza iyi ntera. Ifite imiterere yo kubyimba, guhagarika, guhambira, kwigana, gutatanya, kubungabunga ubushuhe no kurinda colloid. Ibisubizo muburyo butandukanye bwo kwiyegeranya birashobora gutegurwa. Ntibihindagurika munsi yubushyuhe busanzwe nigitutu, irinde ubushuhe, ubushyuhe, nubushyuhe bwo hejuru, kandi ufite umunyu mwinshi udasanzwe kuri dielectrics, kandi igisubizo cyamazi cyayo ituma imyunyu myinshi yumunyu igumaho.
Ibintu by'ingenzi:
Nka surfactant idafite ionic, hydroxyethyl selulose ifite imitungo ikurikira usibye kubyimba, guhagarika, guhambira, kureremba, gukora firime, gutatanya, kubika amazi no gutanga colloide ikingira:
1.
2. Ntabwo ari ionic kandi irashobora kubana hamwe nandi moko menshi yandi mazi ashonga polymers, surfactants, nu munyu. Nibyimbye byiza bya colloidal kubyibushye cyane bya electrolyte ibisubizo;
3. Ubushobozi bwo gufata amazi bukubye kabiri ubwa methyl selile, kandi bufite uburyo bwiza bwo gutembera neza.
4. Ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, ubushobozi bwo gukwirakwiza HEC nububi, ariko ubushobozi bwo gukingira colloid nabwo bukomeye.
Umwanya wo gusaba
Ikoreshwa nka adhesive, surfactant, colloidal agent agent, dispersant, emulsifier na dispersion stabilisateur, nibindi. Ifite uburyo bwinshi bwo gukoresha mubijyanye no gutwikira, wino, fibre, gusiga amarangi, gukora impapuro, kwisiga, imiti yica udukoko, gutunganya amabuye y'agaciro, gukuramo amavuta no gukuramo amavuta na ubuvuzi.
1. Ubusanzwe ikoreshwa nkibibyimbye, birinda ibintu, bifata, stabilisateur, ninyongera mugutegura emulisiyo, jellies, amavuta, amavuta yo kwisiga, koza amaso, suppositions, na tableti. Irakoreshwa kandi nka hydrophilique gel na skeleton Ibikoresho, gutegura ubwoko bwa matrix yo gukomeza-kurekura, kandi birashobora no gukoreshwa nka stabilisateur mubiryo.
.
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. Iki gicuruzwa gikoreshwa nkikwirakwizwa rya polymerisation ya peteroli ya peteroli ishingiye kuri peteroli yamenetse, polystirene na chloride polyvinyl, nibindi bivunika. 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.
Imikorere y'ibicuruzwa
1.
2. Ntabwo ari ionic kandi irashobora kubana nizindi polymers zishonga mumazi, surfactants hamwe numunyu murwego runini. Nibyiza cyane bya colloidal kubyibisubizo birimo dielectrics yibanda cyane;
3. Ubushobozi bwo gufata amazi bukubye kabiri ubwa methyl selulose, kandi bufite uburyo bwiza bwo gutembera neza;
4. Ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, ubushobozi bwo gukwirakwiza HEC nububi, ariko ubushobozi bwo gukingira colloid nabwo bukomeye.
Uburyo bwo gukoreshaHEC？
wongeyeho mugihe cyo gukora
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.
