CMC inoshandisa muCeramic Indasitiri

Sodium carboxymethyl cellulose, Chirungu chidimbu CMC, ceramic indasitiri inowanzozivikanwa se "Sodium CMC", imhando yeanionic substance, inogadzirwa ne cellulose yechisikigo seyakagadzirwa, nekushandurwa kwekemikari uye chena kana mwenje yero poda. CMC ine yakanaka solubility uye inogona kunyungudika kuita yakajeka uye yakafanana mhinduro mumvura inotonhora uye inopisa.

1. Sumo pfupi yeCMCinoshandisa mu ceramics

1.1 kushandiswa kweCMC mune ceramics

1.1.1. Application musimboti

CMC ine yakasarudzika mutsara polymer chimiro. Kana CMC inowedzerwa kumvura, boka rayo re hydrophilic (-Coona) rinosanganiswa nemvura kuti riite danda rakanyungudika, iro rinoparadzira zvishoma nezvishoma CMC mamorekuru mumvura. Iyo network chimiro pakati peCMC polymers inoumbwa nehydrogen bond uye van der Waals simba, zvichiratidza kubatana. Muviri-chaiwo CMC inogona kushandiswa seexcipient, plasticizer uye reinforcer yebillet muindasitiri yeceramic. Kuwedzera huwandu hwakakodzera hweCMC kune billet kunogona kuwedzera simba rekubatanidza rebillet, kuita kuti billet rive nyore kugadzira, kuwedzera simba rekuchinja ne2 ~ 3 nguva, uye kuvandudza kugadzikana kwebillet, kuitira kuti uvandudze chiyero chemhando. Ceramics, kuderedza mutengo wekupedzisira kugadzirisa. Panguva imwecheteyo, nekuda kwekuwedzerwa kweCMC, iyo yekumhanyisa kukurumidza kwegirinhi billet inogona kuvandudzwa uye kugadzirwa kwesimba rekushandisa kunogona kuderedzwa, uye mvura iri mubillet inogona kunyungudutswa zvakaenzana kudzivirira kuomesa uye kuputika, kunyanya muhukuru hukuru. yepasi tile billet uye yakakwenenzverwa zvidhinha billet, mhedzisiro yacho iri pachena. Kuenzaniswa nemamwe maejenti ekusimbisa muviri, CMC yakanangana nemuviri ine zvinotevera hunhu:

(1) shoma dosage: iyo dosage kazhinji isingasviki 0.1%, inova 1/5 ~ 1/3 yeimwe inosimbisa muviri mumiriri, nepo kukotama kwemuviri wegirinhi kuri pachena uye mutengo unogona kudzikiswa.

(2) kunaka kwekupisa kurasikirwa: mushure mekupisa zvinenge pasina madota, hapana zvakasara, hazvikanganisi ruvara rwegirini.

(3) nekurembera kwakanaka: kudzivirira murombo mbishi zvinhu uye pulp kunaya, kuitira kuti slurry ipararire zvakaenzana.

(4) Pfeka kuramba: mukukuya kwebhora, iyo molecular chain haina kukuvadzwa.

1.1.2. Nzira yekuwedzera

Iyo yakawanda yakawanda yeCMC mubillet ndeye 0.03 ~ 0.3%, iyo inogona kugadziriswa maererano nezvinodiwa chaizvo. Kune iyo slurry ine yakawanda yakashata mbishi zvinhu mune formula, CMC inogona kuwedzerwa kune bhora chigayo uye pasi pamwe chete nematope, teerera kune yunifomu kupararira, kuti irege kunetsa kunyungudika mushure mekusangana, kana CMC inogona. kunyungudutswa nemvura na1:30 zvakasiyana uye wozowedzerwa kune bhora paguyo rekusanganisa 1 ~ 5 maawa vasati vakuya.

1.2. Kushandiswa kweCMC mune glaze slurry

1.2.1 Mitemo yekushandisa

Glaze paste yakakosha TYPE CMC yakanakisa performance stabilizer uye binder, inoshandiswa kune ceramic tile pasi glaze uye pamusoro glaze, inogona kuwedzera simba rekubatanidza re glaze slurry uye muviri, nekuti glaze slurry iri nyore kunaya uye kusagadzikana kusina kunaka, uye CMC nemhando dzese dze kuenderana kwe glaze kwakanaka, ine yakanakisa kupararira uye inodzivirira colloid, zvekuti muviri unopenya uri munzvimbo yakagadzikana yekupararira. Mushure mekuwedzera CMC, kushushikana kwepasi kwe glaze kunogona kuvandudzwa, mvura inogona kudzivirirwa kubva pakupararira kubva ku glaze kuenda kumuviri, kutsetseka kwe glaze kunogona kuwedzera, kuputika uye kutsemuka chiitiko chinokonzerwa nekudonha kwesimba remuviri mushure mekuwedzera. glaze application inogona kudzivirirwa, uye pinhole phenomenon ye glaze inogona zvakare kuderedzwa mushure mekubheka.

1.2.2. Kuwedzera nzira

Huwandu hweCMC hwakawedzerwa kune yepasi glaze uye pamusoro glaze kubva ku0.08 kusvika 0.30%. Inogona kugadziriswa maererano nezvinodiwa chaizvo. Chekutanga, iyo CMC inogadzirirwa kuita 3% aqueous solution. Kana ichida kuchengetwa kwemazuva akati wandei, mhinduro yacho inofanira kuiswa mumudziyo usina mhepo ine mapreservatives akakodzera uye inochengeterwa pakudziya kwakaderera. Zvadaro, mhinduro yacho inosanganiswa zvakafanana ne glaze.

1.3 kushandiswa kweCMC mukudhinda glaze

1.3.1, kudhinda glaze yakakosha CMC ine yakanaka gobvu chivakwa uye kupararira uye kugadzikana, iyo yakakosha CMC kutora tekinoroji nyowani, yakanaka solubility, kujeka kwepamusoro, kunenge kusina insolubles, asi zvakare ine yepamusoro yekuveura kutetepa uye lubrication, inovandudza zvakanyanya kudhinda glaze kudhinda. kuchinjika, kudzikisa chidzitiro, chidzitiro chekuvhara chiitiko, kuderedza nguva yetiweki, painodhinda yakatsetseka kushanda, Yakajeka pateni, yakanaka kuenderana kwemavara.

1.3.2 Huwandu huzhinji hwekuwedzera kudhinda glaze ndeye 1.5-3%. CMC inogona kunyoroveswa ne ethylene glycol uye yakazowedzerwa nemvura kuti iite presoluble, kana 1-5% sodium tripolyphosphate uye ruvara zvinhu zvinogona kuoma zvakakanyiwa pamwe chete, uye ipapo kunyungudutswa nemvura, kuitira kuti zvinhu zvakasiyana-siyana zvinogona kunyungudutswa zvizere uye zvakaenzana.

1.4. Kushandiswa kweCMC mukupinza glaze

1.4.1 Mitemo yekushandisa

Penetration glaze ine yakawanda yakanyungudika munyu, asidhi, uye imwe chikamu chekupinda glaze yakakosha CMC ine yepamusoro asidhi munyu kuramba kugadzikana, ita kuti kupenya kwekupinda mukati mekushandiswa uye kuiswa kuchengetedze kugadzikana viscosity, kudzivirira nekuda kwekuchinja kwe viscosity, ruvara uye. penetration glaze yakakosha CMC mvura inonyungudika, mambure permeability uye kuchengetwa kwemvura kwakanaka kwazvo, kuchengetedza kugadzikana kweinonyungudika munyu glaze kune rubatsiro rwakawanda.

1.4.2. Nzira yekuwedzera

Dissolve CMC ine ethylene glycol, imwe mvura uye yakaoma mumiriri, wozosanganisa zvakanaka neyakanyungudika ruvara mhinduro.

2.CMC inofanira kubhadharwa mukugadzirwa kweceramic

2.1 Mhando dzakasiyana dzeCMC dzinotamba mabasa akasiyana mukugadzirwa kweceramic. Kusarudzwa kwakakodzera kunogona kuzadzisa chinangwa chehupfumi nekubudirira.

2.2. Mune glaze uye kudhinda glaze, hazvifanirwe kunyura zvigadzirwa zveCMC nekuchena kwakaderera, kunyanya mukudhinda glaze, kuchena kwepamusoro CMC nekuchena kwakanyanya, yakanaka asidhi uye munyu kuramba uye kujeka kwakanyanya kunofanirwa kusarudzwa kudzivirira ripples uye pinholes pa glaze. Panguva imwecheteyo, inogona zvakare kudzivirira kushandiswa kweplug mambure, kushata kwemazinga uye ruvara uye zvimwe zviitiko.

2.3 Kana tembiricha yakakwira kana kuti glaze inoda kuiswa kwenguva yakareba, zvinodzivirira zvinofanira kuwedzerwa.

3. Kuongororwa kwezvinetso zvakajairika zveCMC mukugadzirwa kweceramic

3.1. Iyo fluidity yematope haina kunaka uye zvakaoma kuisa glue.

Nekuda kweiyo viscosity yeCMC pachayo, dhaka viscosity yakakwira zvakanyanya, izvo zvinotungamira kune kuoma kwekupuruzira. Mhinduro ndeyekugadzirisa huwandu uye rudzi rwe coagulant, kurudzira inotevera decoagulant formula1) sodium tripolyphosphate 0.3%; (2) sodium tripolyphosphate 0.1% + sodium silicate 0.3%; (3) Sodium humate 0.2%+ sodium tripolyphosphate 0.1%

3.2. Glaze paste uye mafuta ekudhinda zvakatetepa.

Zvikonzero zvekusarudza glaze paste uye kudhinda mafuta ndeaya anotevera1) glaze paste kana kudhinda oiri inonatswa nema microorganisms, kuitira kuti CMC ikundikane. Mhinduro ndeyekugeza chigadziko che glaze paste kana kudhinda mafuta zvakakwana, kana kuwedzera zvinochengetedza zvakadai se formaldehyde uye phenol. (2) Pasi pekuenderera mberi kwekukurudzira kweshear simba, viscosity inoderera. Inokurudzirwa kugadzirisa CMC aqueous solution.

3.3. Namira mesh paunenge uchishandisa kudhinda glaze.

Mhinduro ndeyekugadzirisa huwandu hweCMC, kuitira kuti kudhinda glaze viscosity ine mwero, kana zvichidiwa, kuwedzera mvura shoma kuti iwedzere zvakaenzana.

3.4, kuvharira network, pukuta huwandu hwenguva.

Mhinduro ndeyekuvandudza kujeka uye kunyungudika kweCMC. Kudhinda kugadzirira kwemafuta mushure mekupedzwa kwe120 mesh sieve, mafuta ekudhinda anodawo kupfuura 100 ~ 120 mesh sieve; Rongedza kudhinda glaze viscosity.

3.5, kuchengetwa kwemvura hakuna kunaka, mushure mekudhinda hupfu hwepamusoro, kunokanganisa kudhindwa kunotevera.

Mhinduro ndeyokuwedzera huwandu hweglycerin mukugadzirwa kwekudhinda mafuta ekugadzirira; Chinja kune yakakwira dhigirii yekutsiva (tsiva yakanaka kufanana), yakaderera viscosity CMC kugadzirira kudhinda mafuta.
