High Viscosity CMC

High viscosityCMCichena kana mukaka chena fibrous powder kana magranules, ine density ye 0.5-0.7 g/cm3, inenge isinganhuhwi, isinganakidze, uye hygroscopic. Inonyatso kuparadzirwa mumvura kuita inoonekera colloidal mhinduro, isinganyunguriki muorganic solvents senge ethanol. Iyo pH ye1% aqueous solution ndeye 6.5 kusvika 8.5. Kana pH iri> 10 kana <5, viscosity yeglue ichaderedzwa zvakanyanya, uye kushanda kuchava kwakanakisisa kana pH iri 7. Dhigirii reCMC substitution rinokanganisa zvakananga kunyungudika, emulsification, uye kuwedzera kweCMC. Consistency, kugadzikana, acid resistance uye salt resistance nezvimwe zvinhu.

Zvinowanzotendwa kuti kana dhigirii yekutsiva yakapoteredza 0.6-0.7, emulsifying performance iri nani, uye nekuwedzera kwedhigirii yekutsiva, zvimwe zvivakwa zvinovandudzwa zvinoenderana. Kana iyo dhigirii yekutsiva yakakura kupfuura 0.8, acid yayo kuramba uye munyu kuramba inowedzerwa zvakanyanya. .

Iwo makuru anoratidza kuyera kunaka kweCMC idhigirii rekutsiva (DS) uye kuchena. Kazhinji, zvinhu zveCMC zvakasiyana kana DS yakasiyana; iyo yakakwirira dhigirii yekutsiva, iyo yakasimba kunyungudika, uye zviri nani kuve pachena uye kugadzikana kwemhinduro. Sekureva kwemishumo, kujeka kweCMC kuri nani kana dhigirii rekutsiva iri 0.7-1.2, uye viscosity yemushonga wayo wemvura ndiyo yakakura kana iyo pH kukosha iri 6-9.

Hunhu hweCMC dzakapedzwa zvigadzirwa zvakanyanya zvinoenderana nemhinduro yechigadzirwa. Kana mhinduro yechigadzirwa ichijeka, kune mashoma gel particles, mahara fiber, uye mavara matema etsvina, zvinonyatsosimbiswa kuti mhando yeCMC yakanaka. Kana iyo mhinduro yakasara kwemazuva mashomanana, mhinduro haioneki. Ichena kana turbid, asi ichiri kujeka, icho chiri nani chigadzirwa!

1. Kusuma kupfupi kweyakakwira-viscosity technical giredhi CMC uye yakaderera-viscosity technical giredhi CMC yemafuta ekuchera mvura.

1. CMC madhaka anogona kuita tsime rusvingo kuumba nhete uye yakasimba sefa keke ine yakaderera permeability, kuderedza kurasikirwa mvura.

2. Mushure mekuwedzera CMC kumatope, chigadziro chekuchera chinogona kuwana simba rekutanga rekuveura, kuitira kuti dhaka risunungure nyore gasi rakaputirwa mairi, uye panguva imwe chete, marara anogona kukurumidza kuraswa mugomba rematope.

3. Kuchera madhaka, semamwe kumiswa uye kupararira, kune humwe hupenyu hwesherufu. Kuwedzera CMC kunogona kuita kuti igadzikane uye kurebesa hupenyu hwesherufu.

4. Madhaka ane CMC haawanzobatwa ne mold, saka hazvidikanwi kuchengetedza yakakwirira pH kukosha uye kushandisa zvinodzivirira.

5. Iine CMC semumiririri wekurapa kwekuchera madhaka ekutsvaira mvura, iyo inogona kudzivisa kusvibiswa kwemunyu wakasiyana-siyana.

6. Madhaka ane CMC ane kugadzikana kwakanaka uye anogona kuderedza kurasikirwa kwemvura kunyangwe tembiricha iri pamusoro pe150°C.

Tsanangudzo: CMC ine viscosity yakakwirira uye yakakwirira dhigirii yekutsiva inokodzera madhaka ane density yakaderera, uye CMC ine yakaderera viscosity uye yakakwirira dhigirii yekutsiva inokodzera madhaka ane density yakakwirira. Sarudzo yeCMC inofanirwa kutemerwa zvinoenderana nemamiriro akasiyana senge mhando yedhaka, dunhu, uye kudzika kwetsime.

Main application: MB-CMC3 inobata basa rekusimudza nekudzikisa kurasikirwa kwemvura uye viscosity kusimudza mumvura yekuchera, simende fluid uye fracturing fluid, kuitira kuti iite mabasa ekudzivirira madziro, kutakura kucheka, kudzivirira drill bit, kudzivirira kurasikirwa kwedhaka uye kuwedzera. drilling speed. Wedzera zvakananga kana kuti uite glue uye uwedzere kune dhaka, wedzera 0.1-0.3% kumvura yakachena slurry, uye uwedzere 0.5-0.8% kumvura yemunyu slurry.

2. Kushandiswa kweCMC muindasitiri yekupfeka

Chinangwa chikuru:

Sekugadzikana, inogona kudzivirira kupfekedza kubva pakuparadzana nekuda kwekuchinja kwakapinza kwekushisa.

Senge tackifier, inogona kuita iyo mamiriro eiyo yunifomu yekuputira, kuwana yakanakira kuchengetedza uye kuvaka viscosity, uye kudzivirira yakakomba delamination panguva yekuchengetedza.

Inodzivirira kubva kumadrip uye sags panguva yekushandiswa.

ST, SR yakatevedzana instant CMC inogona kunyungudika zvachose mumaminetsi makumi matatu, ichigadzira yakajeka, yakajeka, yunifomu colloidal mhinduro, pasina kunyura kwenguva refu uye nekukurudzira kwakasimba.

Coating giredhi CMC tekinoroji zviratidzo:

3. Kushandiswa kweCMC muindasitiri yeceramic

Main application: MB-CMC3 inoshandiswa muceramics seretarder, mvura yekuchengetedza mumiririri, thickener uye stabilizer. Mukugadzirwa kweceramic, inoshandiswa mumuviri weceramic, glaze slurry uye kudhinda kuvandudza zvakanyanya kusimba kwemuviri uye kugadzirisa kugadzikana kwe glaze slurry.

4. Kushandiswa kweCMC muindasitiri yekuwachira

Detergent giredhi MB-CMC3: inoshandiswa mune zvekugezesa kudzivirira tsvina kubva pakuiswazve. Nheyo yacho ndeyekuti kune mutual electrostatic repulsion pakati petsvina yakashata uye inochaja CMC mamorekuru adsorbed pajira. Mukuwedzera, CMC inogonawo Kunyatsoita gobvu yakashambidzwa slurry kana sipo mhinduro uye kudzikamisa chimiro chekuumbwa.

5. Kushandiswa kweCMC mumabhizimisi ezuva nezuva emakemikari mazino

Main application: MB-CMC3 inonyanya kumiswa mumakemikari ezuva nezuva, kudzivirira tsvina kubva pakunaya zvakare, kuchengetedza hunyoro, kudzikamisa, uye kukora. Iine zvakanakira kukurumidza kupera uye kushandiswa kuri nyore. Mari yekuwedzera ndeye 0.3% -1.0%. Mushonga wemazino unonyanya kuita basa rekuumba nekubatanidza. Kuburikidza nekuenderana kwayo kwakanakisa, mushonga wemazino unoramba wakagadzikana uye hauparadzanise mvura. Kazhinji, iyo yakakurudzirwa dosage ndeye 0.5-1.5%.

Nhanhatu, kugadzikana kweCMC glue viscosity nekufamba kwenguva, mirairo yekushandisa

1. Nekuda kwehuremu hwemamorekuru hwechigadzirwa ichi, paunenge uchigadzira MB-CMC3 glue, nguva yekunyunguduka inosvika hafu yeawa kureba kupfuura yeyakajairika CMC;

2. Pamusana pehupamhi hwepamusoro hweglue pamusoro pe 1.2%, hazvina kukodzera kushandisa mutsara unopfuura 1.2% apo CMC yakanamatira. Kazhinji, zvinonyanya kukodzera kusarudza glue ine mutsara we 1.0%;

3. Mukusarudza chiyero chekuwedzera cheCMC, chinofanira kusarudzwa maererano nemhando ye graphite, iyo chaiyo nzvimbo uye chiyero che carbon black (conductive agent) yakatumirwa, uye huwandu hwehuwandu hwekuwedzera huri 0.5% ^ 1.0%;

4. Iyo viscosity ye slurry inodzorwa inenge 2500mPa.s, kutsetseka uye kuenzana kwe slurry kuchava nani, iyo inobatsira pakufanana kwekuputira.

Zvinomwe, zvigadzirwa zvemhando uye zvakanakira

1. Iine huremu hwema molecular, iyo inogona kuderedza zvakanyanya kuwanda kweCMC yakawedzerwa, uye panguva imwechete inovimbisa viscosity uye kugadzikana kwe slurry;

2. Huwandu hweCMC hwakawedzerwa muhuwandu hunoderedzwa ne1%, iyo inogona kuwedzera zvinyorwa zvezvinhu zvinoshanda uye kuwedzera chiyero chakakodzera chehuwandu hwechigadzirwa;
