Sodium carboxymethyl selulose, amagambo ahinnye y’icyongereza CMC, bakunze kwita “methyl” mu nganda z’ubutaka, ni ibintu bya anionic, ifu yera cyangwa umuhondo mutoya ikozwe muri selile isanzwe nkibikoresho fatizo kandi byahinduwe mu buryo bwa shimi. . CMC ifite imbaraga zo gukemura kandi irashobora gushonga mugisubizo kibonerana kandi kibonerana kimwe mumazi akonje namazi ashyushye.
1. Intangiriro ngufi yo gukoresha CMC mububumbyi
1.1. Ikoreshwa rya CMC mubutaka
1.1.1, ihame ryo gusaba
CMC ifite imiterere yihariye ya polymer. Iyo CMC yongewe mumazi, itsinda ryayo rya hydrophilique (-COONa) rihuza namazi kugirango ribe urwego rwo gukiza, kuburyo molekile ya CMC ikwirakwizwa buhoro buhoro mumazi. Polimeri ya CMC yishingikiriza kuri hydrogène hamwe nimbaraga za van der Waals. Ingaruka ikora imiterere y'urusobe, bityo ikerekana ubumwe. Umubiri wihariye wa CMC urashobora gukoreshwa nkibintu byoroshye, bya pulasitiki, hamwe nimbaraga zishimangira imibiri yicyatsi munganda zubutaka. Ongeraho umubare ukwiye wa CMC kuri bilet irashobora kongera imbaraga zifatanije na bilet, bigatuma fagitire yoroshye kuyikora, kongera imbaraga za flexural inshuro 2 kugeza kuri 3, no kuzamura ituze rya fagitire, bityo byongera ibicuruzwa byiza cyane igipimo cyibumba no kugabanya ibiciro nyuma yo gutunganya. . Muri icyo gihe, kubera kwiyongera kwa CMC, irashobora kongera umuvuduko wo gutunganya umubiri wicyatsi no kugabanya ingufu zikoreshwa. Irashobora kandi gutuma ubushuhe buri muri bilet bugenda bugabanuka kandi bikarinda gukama no guturika. Cyane cyane iyo ikoreshejwe mubunini bunini bwa tile bilet hamwe na fagitire y'amatafari asennye, ingaruka ni nziza. biragaragara. Ugereranije nibindi byatsi byubaka umubiri, icyatsi kibisi kidasanzwe CMC ifite ibintu bikurikira:
. icyarimwe.
.
.
(4) Kurwanya-abrasion: Mugihe cyo gusya umupira, urunigi rwa molekile ntirwangiritse cyane.
1.1.2, wongeyeho uburyo
Umubare rusange wongeyeho wa CMC muri bilet ni 0.03-0.3%, ushobora guhindurwa uko bikwiye ukurikije ibikenewe. Kubyondo hamwe nibikoresho byinshi bitarumbuka muri formula, CMC irashobora kongerwaho mumashini yumupira kugirango isya hamwe nicyondo, witondere gutatanya kimwe, kugirango bitagorana gushonga nyuma ya agglomeration, cyangwa pre- gushonga CMC n'amazi ku kigereranyo cya 1:30 Ongera ku ruganda rw'umupira hanyuma uvange neza amasaha 1-5 mbere yo gusya.
1.2. Ikoreshwa rya CMC muri glaze slurry
1.2.1. Ihame ryo gusaba
CMC ya glaze slurry ni stabilisateur hamwe na binder hamwe nibikorwa byiza. Ikoreshwa muri glaze yo hepfo hamwe na glaze yo hejuru ya ceramic tile, ishobora kongera imbaraga zihuza hagati ya glaze slurry numubiri. Kuberako glaze slurry yoroshye kugwa kandi ifite umutekano muke, CMC nibindi bitandukanye Guhuza ubu bwoko bwa glaze nibyiza, kandi bifite dispersion nziza hamwe na colloid ikingira, kuburyo glaze iri muburyo butatanye cyane. Nyuma yo kongeramo CMC, uburemere bwubuso bwa glaze burashobora kwiyongera, amazi arashobora gukumirwa gukwirakwira kuva kumurabyo kugeza kumubiri wicyatsi, ubworoherane bwubuso bwa glaze burashobora kwiyongera, no gucika no kuvunika mugihe cyubwikorezi bwatewe na kugabanuka kwimbaraga zumubiri wicyatsi nyuma yo gusiga birashobora kwirindwa. , Pinhole phenomenon hejuru ya glaze nayo irashobora kugabanuka nyuma yo kurasa.
1.2.2. Ongeraho uburyo
Umubare wa CMC wongeyeho muri glaze yo hepfo na glaze yo hejuru muri rusange ni 0.08-0.30%, kandi irashobora guhinduka ukurikije ibikenewe mugihe cyo kuyikoresha. Banza ukore CMC mubisubizo byamazi 3%. Niba ikeneye kubikwa muminsi myinshi, iki gisubizo gikeneye kongerwaho hamwe nuburyo bukwiye bwo kubika ibintu hanyuma bigashyirwa mubintu bifunze, bikabikwa ku bushyuhe buke, hanyuma bikavangwa na glaze neza.
1.3. Gukoresha CMC mugucapisha glaze
1.3.1. CMC idasanzwe yo gucapa glaze ifite umubyimba mwiza, gutandukana no gutuza. Iyi CMC idasanzwe ikoresha tekinolojiya mishya, ifite ubushobozi bwo gukemuka neza, gukorera mu mucyo mwinshi, hafi ntakintu kidashobora gukemuka, kandi ifite imitungo ihebuje yo gutemagura no gusiga amavuta, kunoza cyane imiterere yo gucapa imiterere yo gucapa glaze, kugabanya ibintu byo gufunga no guhagarika ecran, kugabanya umubare byo guhanagura, gucapa neza mugihe gikora, ibishushanyo bisobanutse, hamwe nibara ryiza.
1.3.2. Muri rusange wongeyeho umubare wo kongeramo icapiro ni 1.5-3%. CMC irashobora kwinjizwa na Ethylene glycol hanyuma ikongeramo amazi kugirango ibe yashonga mbere. Irashobora kandi kongerwamo hamwe na 1-5% sodium tripolyphosphate nibikoresho byamabara hamwe. Kuvanga byumye, hanyuma bigashonga n'amazi, kugirango ibikoresho byose bishobore gushonga neza.
1.4. Gukoresha CMC muri oozing glaze
1.4.1. Ihame ryo gusaba
Amaraso ava amaraso arimo umunyu mwinshi ushonga, kandi bimwe muribi birimo aside. Ubwoko bwihariye bwa CMC bwo kuva amaraso glaze ifite aside irike kandi irwanya umunyu, irashobora gutuma ubwiza bwurumuri rwamaraso ruhagarara mugihe cyo kuyikoresha no kuyishyira, kandi ikayirinda kwangirika kubera impinduka zijimye. Ihindura itandukaniro ryamabara, kandi gukomera kwamazi, gutembera mesh no kugumana amazi ya CMC idasanzwe ya glaze yamenetse nibyiza cyane, bikaba bifasha cyane kubungabunga umutekano wamaraso.
1.4.2. Ongeraho uburyo
Kuramo CMC hamwe na Ethylene glycol, igice cyamazi nigikoresho kibanza, hanyuma ukavanga nigisubizo cyamabara yashonze.
2. Ibibazo bigomba kwitabwaho mubikorwa bya CMC mububumbyi
2.1. Ubwoko butandukanye bwa CMC bufite imirimo itandukanye mugukora ubukorikori. Guhitamo neza birashobora kugera ku ntego yubukungu no gukora neza.
2.2. Muburyo bwa glaze hamwe no gucapa glaze, ntugomba gukoresha ibicuruzwa bya CMC bifite isuku nkeya kubihendutse, cyane cyane mugucapisha glaze, ugomba guhitamo CMC ifite isuku nyinshi ifite isuku nyinshi, aside nziza hamwe n’umunyu mwinshi, hamwe no gukorera mu mucyo mwinshi kugirango wirinde glaze Ripples na pinholes kugaragara hejuru. Mugihe kimwe, irashobora kandi gukumira ibintu byo gucomeka net, kuringaniza nabi no gutandukanya ibara mugihe cyo gukoresha.
2.3. Niba ubushyuhe buri hejuru cyangwa glaze slurry igomba gushyirwaho igihe kirekire, imiti igabanya ubukana.
3. Isesengura ryibibazo bisanzwe byaCMC muri ceramicumusaruro
3.1. Amazi y'ibyondo ntabwo ari meza, kandi biragoye kurekura kole.
Bitewe nubwiza bwayo, CMC izatera ubwiza bwibyondo kuba hejuru cyane, bikagora kurekura icyondo. Igisubizo nuguhindura umubare nubwoko bwa coagulant. Harasabwa formula ikurikira ya decoagulant: (1) sodium tripolyphosphate 0.3%; (2) sodium tripolyphosifate 0.1% + ikirahuri cy'amazi 0.3%; (3) acide humic Sodium 0.2% + sodium tripolyphosifate 0.1%
3.2. Amashanyarazi ya glaze na wino yo gucapa biroroshye.
Impamvu zituma glaze itobora hamwe na wino yo gucapa inanutse ni izi zikurikira: (1) Amashanyarazi ya glaze cyangwa wino yo gucapa yangizwa na mikorobe, bigatuma CMC itemewe. Igisubizo nukwoza neza ibikoresho bya glaze slurry cyangwa wino, cyangwa ukongeramo imiti igabanya ubukana nka formaldehyde na fenol. . Birasabwa kongeramo CMC igisubizo cyamazi kugirango uhindure mugihe ukoresha.
3.3. Shyira inshundura mugihe ukoresheje icapiro.
Igisubizo nuguhindura ingano ya CMC kugirango ubwiza bwibicapo byacapwe buringaniye, kandi nibiba ngombwa, ongeramo amazi make kugirango ubyuke neza.
3.4. Hariho inshuro nyinshi zo guhagarika imiyoboro no gusukura.
Igisubizo nukuzamura gukorera mu mucyo no gukemuka kwa CMC; nyuma yo gutegura amavuta yo gucapa, unyuze mumashanyarazi ya mesh 120, kandi amavuta yo gucapa nayo agomba kunyura mumashanyarazi 100-120; hindura ubwiza bwimyandikire ya glaze.
3.5. Kubika amazi ntabwo ari byiza, kandi hejuru yururabyo bizahinduka nyuma yo gucapa, bizagira ingaruka kumucapiro utaha.
Igisubizo nukwongera urugero rwa glycerine mugutegura amavuta yo gucapa; koresha iciriritse kandi ritoya rya CMC hamwe nimpamyabumenyi yo hejuru yo gusimbuza (uburinganire bwiza bwo gusimbuza) kugirango utegure amavuta yo gucapa.
