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 ibintu byiza nko kubyimba, guhagarika, gutatanya, kwigana, guhuza, gukora firime, kurinda ubushuhe no gutanga colloide ikingira, yakoreshejwe cyane mubuvuzi bwuruhu, gushakisha amavuta, gutwikira, kubaka, ubuvuzi nibiribwa, imyenda, gukora impapuro na polymers.Polymerisation hamwe nizindi nzego.Igipimo cya mesh 40 mesh 99%;
Ibigaragara: umweru cyangwa umuhondo fibrous cyangwa ifu ikomeye, idafite uburozi, impumuro nziza, byoroshye gushonga mumazi.Kudashonga muri rusange ibishishwa kama.
Hydroxyethyl selile
Mu ntera ya PH agaciro ka 2-12, ihinduka ryijimye ni rito, ariko ibishishwa bigabanuka kurenza iyi ntera.Ifite imiterere yo kubyimba, guhagarika, guhuza, kwigana, gutatanya, kugumana ubushuhe no kurinda colloid.Ibisubizo byurwego rutandukanye rwubwiza birashobora gutegurwa.Ntigihungabana mubushyuhe busanzwe nigitutu, birinda ubushuhe, ubushyuhe nubushyuhe bwo hejuru, kandi bifite uburyo bwiza budasanzwe bwo gushiramo umunyu kuri dielectrics, kandi igisubizo cyamazi cyemerewe kuba kirimo imyunyu myinshi kandi ihamye.
Ibintu byingenzi: Nka surfactant itari ionic, hydroxyethyl selulose ifite imitungo ikurikira usibye kubyimba, guhagarika, guhambira, flotation, gukora firime, gutatanya, kubika amazi no gutanga colloide ikingira:
1. HEC irashobora gushonga mumazi ashyushye cyangwa akonje, kandi ntigwa kugwa mubushyuhe bwinshi cyangwa kubira, bigatuma igira ibintu byinshi biranga ibishishwa hamwe nubusembwa, hamwe nubushuhe butari ubushyuhe;
2. Ntabwo ari ionic kandi irashobora kubana hamwe nandi moko menshi yandi mashanyarazi ya elegitoronike, surfactants hamwe nu munyu, kandi ni umubyimba mwiza wa colloidal urimo ibisubizo byinshi bya electrolyte;
3. Ubushobozi bwo gufata amazi bwikubye kabiri ubwa methyl selulose, kandi bufite gahunda nziza yo gutembera.
4. Ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, ubushobozi bwo gukwirakwiza HEC nububi, ariko colloid ikingira ifite ubushobozi bukomeye.
Ububiko bwa porogaramu
Ikoreshwa nka adhesive, surfactant, colloid agent agent, dispersant, emulsifier na dispersion stabilisateur.Ifite uburyo bwinshi bwo gukoresha muburyo bwo gutwikira, wino, fibre, gusiga irangi, gukora impapuro, kwisiga, imiti yica udukoko, gutunganya amabuye y'agaciro, gukuramo amavuta nubuvuzi.
1. Mubisanzwe bikoreshwa nkibibyimba, ibikoresho birinda, bifata, stabilisateur ninyongera mugutegura emulsiyo, gel, amavuta, amavuta yo kwisiga, ibikoresho byoza amaso, suppository na tableti, nayo ikoreshwa nka gel hydrophilique, ibikoresho bya skeleton, gutegura skeleton ikomeza-kurekura. , kandi irashobora no gukoreshwa nka stabilisateur mubiryo.
2. Ikoreshwa nkibikoresho bingana mu nganda z’imyenda, guhuza, kubyimba, kwigana, gutuza hamwe n’abandi bafasha mu bikoresho bya elegitoroniki n’inganda zoroheje.
3. Ikoreshwa nkigabanya umubyimba no kuyungurura kugabanya amazi ashingiye kumazi no gutembera, kandi bifite ingaruka zigaragara mubyuma byamazi yumunyu.Irashobora kandi gukoreshwa nkigikoresho cyo kugenzura ibihombo byamazi ya sima.Irashobora guhuzwa hamwe nicyuma cya polyvalent kugirango ikore geles.
4. Iki gicuruzwa gikoreshwa mugukwirakwiza amazi ashingiye kumazi ya gel yamenetse, polystirene na chloride polyvinyl chloride mumavuta yamenetse.Irashobora kandi gukoreshwa nkibyimbye bya emulsiyo mu nganda zisiga amarangi, irwanya ubukonje bukabije mu nganda za elegitoroniki, inzitizi ya sima coagulation hamwe n’umukozi ugumana ubuhehere mu nganda zubaka.Glazing hamwe nu menyo wamenyo yinganda zubutaka.Ikoreshwa kandi cyane mu gucapa no gusiga irangi, imyenda, gukora impapuro, imiti, isuku, ibiryo, itabi, imiti yica udukoko hamwe n’ibikoresho bizimya umuriro.
5. Ikoreshwa nka surfactant, colloid agent agent, stabilisateur ya emulion ya vinyl chloride, vinyl acetate nizindi emulisiyo, hamwe na latx tackifier, dispersant, stabilisateur dispersion, nibindi bikoreshwa cyane mubitambaro, fibre, irangi, gukora impapuro, kwisiga, ubuvuzi, imiti yica udukoko, nibindi Ifite kandi byinshi mubikorwa byo gukuramo amavuta ninganda zimashini.
6. Hydroxyethyl selulose ifite ibikorwa byubuso, kubyimba, guhagarika, guhambira, kwigana, gukora firime, gutatanya, kubika amazi no gutanga uburinzi mubikorwa bya farumasi bikomeye kandi byamazi.
7. Ikoreshwa nk'isakara mugukoresha peteroli ikomoka kuri peteroli ishingiye kuri gel yameneka, polyvinyl chloride na polystirene.Irashobora kandi gukoreshwa nkibyimbye bya emulsiyo munganda zikora amarangi, inhibitor ya sima coagulation hamwe nogukomeza kubika amazi munganda zubwubatsi, ibikoresho byo gusiga amarangi hamwe n’amenyo yangiza amenyo mu nganda zubutaka.Ikoreshwa kandi cyane mu gucapa no gusiga irangi, imyenda, gukora impapuro, ubuvuzi, isuku, ibiryo, itabi n’imiti yica udukoko n’indi nganda.
Gukora ibicuruzwa
1. HEC irashobora gushonga mumazi ashyushye cyangwa akonje, kandi ntigwa kugwa mubushyuhe bwinshi cyangwa kubira, kuburyo ifite uburyo bwinshi bwo kwikemurira no kuranga ibishishwa, hamwe nubushuhe butari ubushyuhe;
2. Ibidafite ionic ubwabyo birashobora kubana hamwe nandi moko menshi yandi mashanyarazi ya elegitoronike, amazi hamwe nu munyu, kandi ni umubyimba mwiza wa colloidal urimo ibisubizo byinshi bya dielectric;
3. Ubushobozi bwo gufata amazi bukubye kabiri ubwa methyl selulose, kandi bufite gahunda nziza yo gutembera;
4. Ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, ubushobozi bwo gukwirakwiza HEC nububi, ariko colloid ikingira ifite ubushobozi bukomeye.
Uburyo bwo kuzinga
Injira muburyo butaziguye
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 shyiramo imiti igabanya ubukana, inyongeramusaruro ya alkaline nka pigment, imiti ikwirakwiza, amazi ya amoniya.
5. Kangura kugeza hydroxyethyl selulose yose yashonze burundu (viscosity yumuti wiyongera cyane) mbere yo kongeramo ibindi bice muri formula, hanyuma ugasya kugeza ibicuruzwa byarangiye.
Uruhare rwa hydroxyethyl selile mu bigize imiti yo kwisiga?Amazi ya elegitoronike ya polymer akoreshwa mu kwisiga agabanijwemo ibyiciro bibiri: karemano na sintetike.
Amazi asanzwe ya elegitoronike ya polymer arimo: ibinyamisogwe, amase y’ibimera, gelatine y’inyamaswa, nibindi, ariko ubuziranenge ntibuhindagurika, byoroshye ingaruka z’ikirere, ibidukikije by’imiterere, umusaruro muke, kandi byangirika byoroshye na bagiteri.
Amazi ya sintetike yamazi ya polymer arimo inzoga zirimo polyvinyl alcool, polyvinylpyrrolidone, nibindi, bifite imiterere ihamye, kurakara uruhu ruto hamwe nigiciro gito, kuburyo basimbuye ibimera bisanzwe byamazi ya polymer hanyuma biba isoko nyamukuru yibikoresho fatizo bya colloid.
Igabanijwemo kandi igice cya sintetike na sintetike yamazi-soluble polymer.
Semi-synthique yamazi-soluble polymer ivanze ikoreshwa kenshi: methyl selulose, Ethyl selulose, sodium carboxymethyl selulose, hydroxyethyl selulose, na guar gum nibiyikomokaho.
Amazi ya sintetike yamazi ya elegitoronike akoreshwa cyane: inzoga za polyvinyl, polyvinylpyrrolidone, acide acrylic polymer, nibindi.
Ibi bikoreshwa mubintu byo kwisiga nkibifatika, kubyimbye, abakora firime, hamwe na stabilisateur ya emulsion.
