CMC ikoresha mu nganda zubutaka

Sodium carboxymethyl selile, impfunyapfunyo yicyongereza CMC, inganda zubutaka zizwi cyane nka “Sodium CMC“, Ni ubwoko bwa anionic, bukozwe muri selile isanzwe nkibikoresho fatizo, muguhindura imiti hamwe nifu yumuhondo yera cyangwa yoroheje. CMC ifite imbaraga zo gukemura kandi irashobora gushonga mugisubizo kiboneye kandi kimwe mumazi akonje kandi ashyushye.

1. Intangiriro muri make ya CMCikoresha mu bukerarugendo

1.1 ikoreshwa rya CMC mububumbyi

1.1.1. Ihame ryo gusaba

CMC ifite imiterere yihariye ya polymer. Iyo CMC yongewe mumazi, itsinda ryayo hydrophilique (-Coona) ihujwe namazi kugirango igire urwego rukemutse, rugenda rukwirakwiza buhoro buhoro molekile ya CMC mumazi. Imiterere y'urusobe hagati ya polimeri ya CMC ikorwa na hydrogène ya hydrogène n'imbaraga za van der Waals, bityo bikerekana ubumwe. Umubiri wihariye wa CMC urashobora gukoreshwa nkibintu byoroshye, plasitike hamwe nogukomeza bilet mu nganda zubutaka. Kongera umubare ukwiye wa CMC kuri bilet birashobora kongera imbaraga zo guhuza fagitire, bigatuma fagitire yoroshye kuyikora, kongera imbaraga za flexural inshuro 2 ~ 3, no kuzamura ituze rya fagitire, kugirango uzamure igipimo cyiza cya ububumbyi, gabanya ikiguzi cyo gutunganya nyuma. Muri icyo gihe, bitewe n’inyongera ya CMC, umuvuduko wo gutunganya fagitire y’icyatsi urashobora kunozwa no gukoresha ingufu z’umusaruro urashobora kugabanuka, kandi amazi yo muri bilet arashobora guhumeka neza kugirango birinde gukama no guturika, cyane cyane mu bunini ya etage ya tile bilet hamwe namatafari yamatafari, ingaruka ziragaragara. Ugereranije nibindi bikoresho bikomeza umubiri, CMC yihariye umubiri ifite ibintu bikurikira:

.

(2) igihombo cyiza cyo gutwika: nyuma yo gutwika hafi nta ivu, nta bisigara, ntabwo bigira ingaruka kumabara yicyatsi.

.

(4) Kwambara birwanya: muburyo bwo gusya umupira, urunigi rwa molekile ntirwangiritse cyane.

1.1.2. Uburyo bwo kongeramo

Umubare rusange wa CMC muri bilet ni 0.03 ~ 0.3%, ushobora guhindurwa ukurikije ibikenewe. Kubitotsi hamwe nibikoresho byinshi bibisi bikennye muri formula, CMC irashobora kongerwaho mumashini yumupira hamwe nubutaka hamwe nicyondo, ukitondera gutatanya kimwe, kugirango bitagorana gushonga nyuma ya agglomeration, cyangwa CMC irashobora gutegekwa namazi saa 1h30 ukwayo hanyuma ukongerwaho mumupira wumupira kugirango uvange amasaha 1 ~ 5 mbere yo gusya.

1.2. Ikoreshwa rya CMC muri glaze slurry

1.2.1 Ihame ryo gusaba

Glaze paste idasanzwe TYPE CMC ninziza nziza ya stabilisateur na binder, ikoreshwa kuri ceramic tile hepfo glaze hamwe nubuso bwa glaze, irashobora kongera imbaraga zihuza za glaze slurry numubiri, kuko glaze slurry byoroshye kugwa nubushyuhe butajegajega, na CMC nubwoko bwose. guhuza glaze nibyiza, bifite dispersion nziza hamwe na colloid ikingira, kuburyo umubiri wa glaze uri muburyo butatanye cyane. Nyuma yo kongeramo CMC, uburemere bwubuso bwa glaze burashobora kunozwa, amazi arashobora gukumirwa gukwirakwira kuva kumurabyo kugeza kumubiri, ubworoherane bwa glaze burashobora kwiyongera, ibintu byo guturika no kuvunika biterwa no kugabanuka kwimbaraga zumubiri nyuma gushira glaze birashobora kwirindwa, kandi pinhole phenomenon ya glaze nayo irashobora kugabanuka nyuma yo guteka.

1.2.2. Ongeraho uburyo

Ingano ya CMC yongewe kumurongo wo hasi hamwe na glaze yo hejuru iri hagati ya 0.08 kugeza 0,30%. Irashobora guhinduka ukurikije ibikenewe. Ubwa mbere, CMC yateguwe mubisubizo byamazi 3%. Niba ikeneye kubikwa muminsi myinshi, igisubizo kigomba gushyirwa mubintu byumuyaga mwinshi hamwe nuburinzi bukwiye kandi bikabikwa mubushyuhe buke. Noneho, igisubizo kivanze neza na glaze.

1.3 ikoreshwa rya CMC mugucapisha glaze

1.3.1. guhuza n'imihindagurikire, kugabanya ecran, guhagarika ecran ya ecran, kugabanya ibihe byurusobe, mugihe icapiro rikorwa neza, Kugaragara neza, amabara meza.

1.3.2 Umubare rusange wo kongeramo glaze ni 1.5-3%. CMC irashobora gushiramo Ethylene glycol hanyuma ikongerwamo namazi kugirango itangirika, cyangwa 1-5% sodium tripolyphosphate nibikoresho byamabara bishobora gukama bivanze hamwe, hanyuma bigashonga namazi, kugirango ibikoresho bitandukanye bishobora gushonga byuzuye kandi bingana.

1.4. Gushyira mu bikorwa CMC muri glaze

1.4.1 Ihame ryo gusaba

Ikirahure cyinjira kirimo umunyu mwinshi, aside, hamwe na glaze ya glaze idasanzwe ya CMC ifite imbaraga zo kurwanya umunyu mwinshi wa aside, ituma glaze yinjira muburyo bwo kuyikoresha no kuyishyira mu bikorwa bikomeza kwifata neza, birinda bitewe nimpinduka zijimye, ibara na penetration glaze idasanzwe ya CMC ibora, gushiramo net no kubika amazi nibyiza cyane, kugirango ugumane ituze ryumunyu wumunyu ushonga ufite ubufasha bwinshi.

1.4.2. Uburyo bwo kongeramo

Kuramo CMC hamwe na Ethylene glycol, amazi amwe n'amwe akomeye, hanyuma uvange neza numuti wamabara yashonze.

2.CMC igomba kwitabwaho mubikorwa byubutaka

2.1 Ubwoko butandukanye bwa CMC bugira uruhare rutandukanye mubikorwa byubutaka. Guhitamo neza birashobora kugera ku ntego yubukungu no gukora neza.

2.2. Muri glaze no gucapa glaze, ntabwo ari ngombwa guhuza ibicuruzwa bya CMC bifite isuku nke, cyane cyane mumashanyarazi yo gucapa, isuku nyinshi ya CMC ifite isuku nyinshi, aside nziza hamwe n’umunyu mwinshi hamwe n’umucyo mwinshi bigomba gutoranywa kugirango hirindwe imvururu n’ibinini kuri glaze. Mugihe kimwe, irashobora kandi gukumira ikoreshwa rya plug net, kuringaniza ibara hamwe nibara nibindi bintu.

2.3 Niba ubushyuhe buri hejuru cyangwa glaze ikeneye gushyirwaho igihe kirekire, imiti igabanya ubukana.

3. Isesengura ryibibazo bisanzwe bya CMC mubikorwa byubutaka

3.1. Amazi y'ibyondo ntabwo ari meza kandi biragoye gushyira kole.

Bitewe n'ubukonje bwa CMC ubwayo, ubwiza bw'ibyondo buri hejuru cyane, biganisha ku ngorane zo gutemba. Igisubizo nuguhindura ingano nubwoko bwa coagulant, tekereza formula ikurikira1) sodium tripolyphosifate 0.3%; (2) sodium tripolyphosphate 0.1% + sodium silike 0.3%; (3) Sodium isuzugura 0.2% + sodium tripolyphosifate 0.1%

3.2. Glaze paste hamwe namavuta yo gucapa biroroshye.

Impamvu zo guhitamo glaze paste no gucapa amavuta naya akurikira1) glaze paste cyangwa amavuta yo gucapa yangizwa na mikorobe, kugirango CMC inanirwe. Igisubizo nukwoza kontineri ya glaze paste cyangwa gucapa amavuta neza, cyangwa kongeramo imiti igabanya ubukana nka formaldehyde na fenol. (2) Mugihe gikomeza gukurura imbaraga zogosha, ubwiza buragabanuka. Birasabwa guhindura CMC igisubizo cyamazi.

3.3. Shyira mesh mugihe ukoresheje glaze yo gucapa.

Igisubizo nuguhindura ingano ya CMC, kugirango icapiro rya glaze viscosity iringaniye, nibiba ngombwa, ongeramo amazi make kugirango ubyuke neza.

3.4, guhagarika umuyoboro, guhanagura inshuro.

Igisubizo nukuzamura umucyo no gukemuka kwa CMC. Gucapa amavuta yo gutegura nyuma yo kurangiza amashanyarazi ya mesh 120, gusohora amavuta nabyo bigomba kunyura 100 m 120; Hindura icapiro rya glaze.

3.5, kubika amazi ntabwo ari byiza, nyuma yo gucapa ifu yo hejuru, bigira ingaruka kumyandikire ikurikira.

Igisubizo nukwongera urugero rwa glycerine mugikorwa cyo gucapa amavuta; Hindura kurwego rwo hejuru rwo gusimbuza (gusimbuza uburinganire bwiza), ubukonje buke CMC kugirango utegure amavuta yo gucapa.
