1. Methylcellse (MC)
Ipamba itunganijwe ifitanye isano na Alkali, ether ether yakozwe binyuze mu buryo bw'imyitwarire na methane chloride nkabakozi bahorera. Mubisanzwe, urwego rwo gusimburwa ni 1.6 ~ 2.0, kandi kwikebana nabyo bitandukanye nuburyo butandukanye bwo gusimburwa. Ni iya Not-ionic selile.
. Igisubizo cyacyo gihamye cyane murwego rwa PH = 3 ~ 12. Ifite neza hamwe nigitako, Guar gum, nibindi nibindi byinshi. Iyo ubushyuhe bugera ku bushyuhe bwa gelale, pelation ibaho.
. Mubisanzwe, niba amafaranga yongeyeho ari manini, igorofa ni nto, kandi viscometity nini, igipimo cyo kugumana amazi ni kinini. Muri bo, ingano yo kongenge ifite ingaruka zikomeye ku gipimo cyo kugumana amazi, kandi urwego rwa vicosity ntabwo ruringaniye mu rwego rwo kugabana amazi. Igipimo cyo gusebanya cyane cyane giterwa nurwego rwo guhindura hejuru yubuso bwa selire hamwe nibyiza. Muri erebire yavuzwe haruguru, Methyl selile na hydroxypropyl methyl Methyl ifite ibiciro byamazi menshi.
. Mubisanzwe, hejuru yubushyuhe, ihohoterwa rikabije. Niba ubushyuhe bwa minisiteri burenze 40 ° C, ugumana amazi ya methyl selile bizagabanuka cyane, bigira ingaruka zikomeye kubakwa kuri minisiteri.
. "Imyitozo" ikubiyemo imbaraga zifatika zumvaga hagati yigikoresho cyo gusabana nurukuta, ni ukuvuga ko kurwanya minisiteri. Kubungabunga ni byinshi, kurwanya imisiteri ari nini, kandi imbaraga zisabwa n'abakozi mu buryo bwo gukoresha nacyo ni kinini, kandi imikorere y'ubwubatsi ya minisiteri irakennye. Methyl Adherilose Ashesion ari kurwego ruciriritse mubicuruzwa bya selile.
2. HydroxyPropylmethylcellcellCellse (HPMC)
HydroxyPropyl Methylcellse nubu bwoko bwa selile birasohoka no kurya byagendaga byiyongera vuba cyane mumyaka yashize. Nibintu bitari uonic bivanze ether bikozwe mu ipamba inoze nyuma ya alkaliation, ukoresheje ibyatsi bya proplene na methyl chloride nkabakozi bashya, binyuze mu ruhererekane. Urwego rwo gusimbuza ni 1.2 ~ 2.0. Imitungo yayo iratandukanye kubipimo bitandukanye bya uburyo na hydroxyproppopyl.
. Ariko ubushyuhe bwa pelale mumazi ashyushye burenze ivya methyl selile. Kudakemura mumazi akonje nabyo birateye imbere cyane ugereranije na methyl selile.
. Ubushyuhe bugira ingaruka kandi ku rubyiruko, uko ubushyuhe bwiyongera, vicosity igabanuka. Ariko, viscosity yayo yo hejuru ifite ingaruka zo hepfo kurenza methyl selile. Igisubizo cyacyo kirahagaze mugihe kibitswe mubushyuhe bwicyumba.
.
. Amazi ya Caustic Soda namazi ntabwo afite ingaruka nke kubikorwa byayo, ariko alkali irashobora kwihutisha iseswa ryayo kandi ryongerera ubuyobe. HydroxyPropyl Methylcellse irahamye muminyuhuri isanzwe, ariko iyo kwibanda ku gisubizo cyumunyu hejuru, viscogity ya hydroxyPropyl methylcellse igisubizo gikunda kwiyongera.
. Nka Polyvinyl Inzoga, ibikatsi bya Ether, gum yimboga, nibindi
. Amahirwe ya hydroxyPropyl methylcellse kugirango ubwubatsi bwimirire ariruta uw'inditi.
3. Hydroxyyeryl Cellulose (HEC)
Ikozwe mu ipamba yatunganijwe yavuwe na Alkali, kandi yabyakiriye okiside okiside ya Ethyne nk'abakozi bahobera imbere ya Acetone. Urwego rwo gusimbuza ni 1.5 ~ 2.0. Ifite hydrofilire ikomeye kandi biroroshye gukuramo ubushuhe.
(1) Hydroxyyethyll selile irashonje mumazi akonje, ariko biragoye gusesa mumazi ashyushye. Igisubizo cyacyo kirahamye ku bushyuhe burebure nta na umwelle. Irashobora gukoreshwa igihe kirekire munsi yubushyuhe bwo hejuru muri minisiteri, ariko kugumana amazi biri hasi kurenza ibya methyl selile.
(2) Hydroxyyethyl selile irahamye aside rusange na alkali. Alkali irashobora kwihutisha iseswa ryayo kandi ryongerera ubuyobe. Gutagira nabi mumazi birababaje gato kurenza ibya Methyl Celllease na HydroxyPropyl Methyl Cellulose. .
(3) Hydroxyyethyl selile ifite imikorere myiza yo kurwanya minisiteri, ariko ifite igihe kirekire cyo kuditana.
.
4. Carboxymethyl Cellulose (CMC)
Ihangane na selile ether ikozwe muri fibre karemano (ipamba, nibindi) yavuwe na alkali kandi ikoreshwa nkumukozi wabuze akoresheje urukurikirane rwibitabo. Urwego rwo gusimbuza ni 0.4 ~ 1.4, kandi imikorere yacyo igira ingaruka kurwego rwo gusimburwa.
.
. Iyo ubushyuhe burenze 50 ° C, viscosity ntasubirwaho.
(3) Guhagarara kwayo byatewe cyane na PH. Mubisanzwe, irashobora gukoreshwa muri minisiteri ishingiye ku nshinge, ariko ntabwo muri minisiteri ishingiye kuri sima. Iyo alkaline cyane, itakaza vino.
(4) Kugumana amazi ari munsi yiya Methyl selile. Ifite ingaruka zidindiza kuri minisiteri ishingiye kuri Gypsum kandi igabanya imbaraga. Ariko, igiciro cya carboxymethyl selile irari munsi cyane kurenza iya methyl selile
