Siab viscosityCMCyog dawb los yog milky dawb fibrous hmoov los yog granules, nrog ib tug ceev ntawm 0.5-0.7 g / cm3, yuav luag odorless, tasteless, thiab hygroscopic. Yooj yim dispersed nyob rau hauv dej los tsim cov pob tshab colloidal tov, insoluble nyob rau hauv cov organic solvents xws li ethanol. pH ntawm 1% aqueous tov yog 6.5 txog 8.5. Thaum pH yog> 10 lossis <5, viscosity ntawm cov kua nplaum yuav txo qis, thiab qhov kev ua tau zoo yuav zoo tshaj plaws thaum pH yog 7. Qhov degree ntawm CMC hloov pauv ncaj qha cuam tshuam rau solubility, emulsification, thiab txhim kho CMC. Consistency, stability, acid kuj thiab ntsev kuj thiab lwm yam khoom.
Nws yog feem ntau ntseeg tias thaum lub degree ntawm kev hloov yog nyob ib ncig ntawm 0.6-0.7, lub emulsifying kev ua tau zoo yog zoo dua, thiab nrog rau kev nce qib ntawm kev hloov, lwm yam khoom yog txhim kho raws li. Thaum qhov kev hloov pauv ntau dua 0.8, nws cov tshuaj tiv thaiv acid thiab ntsev kuj tau txhim kho. .
Cov cim tseem ceeb los ntsuas qhov zoo ntawm CMC yog qib kev hloov pauv (DS) thiab purity. Feem ntau, cov khoom ntawm CMC txawv yog tias DS txawv; qhov siab dua qhov kev hloov pauv, qhov muaj zog dua qhov solubility, thiab qhov zoo dua qhov pom thiab ruaj khov ntawm cov tshuaj. Raws li cov lus ceeb toom, lub pob tshab ntawm CMC yog qhov zoo dua thaum qhov kev hloov pauv yog 0.7-1.2, thiab viscosity ntawm nws cov kua dej yog qhov loj tshaj plaws thaum pH tus nqi yog 6-9.
Qhov zoo ntawm CMC cov khoom tiav feem ntau yog nyob ntawm qhov kev daws teeb meem ntawm cov khoom. Yog hais tias qhov kev daws teeb meem ntawm cov khoom yog qhov tseeb, muaj ob peb gel hais, dawb fibers, thiab dub me ntsis ntawm impurities, nws yeej paub tseeb tias qhov zoo ntawm CMC yog zoo. Yog tias cov tshuaj tau tso tseg rau ob peb hnub, cov tshuaj tsis tshwm sim. Dawb los yog turbid, tab sis tseem meej heev, uas yog ib yam khoom zoo dua!
1. Kev taw qhia luv luv ntawm high-viscosity technical qib CMC thiab low-viscosity technical grade CMC rau roj drilling kua
1. CMC av nkos tuaj yeem ua rau cov phab ntsa zoo tsim lub ncuav mog qab zib nyias thiab ruaj khov nrog cov permeability tsawg, txo cov dej tsis zoo.
2. Tom qab ntxiv CMC rau cov av nkos, cov pob zeb drilling tuaj yeem tau txais lub zog pib qis qis, kom cov av nkos tau yooj yim tso cov roj ntim rau hauv nws, thiab tib lub sijhawm, cov khib nyiab tuaj yeem muab pov tseg sai sai hauv cov av nkos.
3. Drilling av, zoo li lwm yam suspensions thiab dispersions, muaj lub neej txee. Ntxiv CMC tuaj yeem ua kom ruaj khov thiab ua kom lub neej ntev.
4. Cov av nkos uas muaj CMC tsis tshua muaj kev cuam tshuam los ntawm pwm, yog li nws tsis tas yuav tsum tswj hwm tus nqi pH siab thiab siv cov tshuaj tua kab mob.
5. Muaj CMC raws li tus neeg saib xyuas kev kho mob rau cov av nkos flushing kua, uas tuaj yeem tiv taus cov pa phem ntawm ntau cov ntsev soluble.
6. CMC-muaj av nkos muaj kev ruaj ntseg zoo thiab tuaj yeem txo cov dej poob txawm tias qhov kub siab tshaj 150 ° C.
Cov Lus Qhia: CMC nrog cov viscosity siab thiab qib siab ntawm kev hloov pauv yog tsim rau cov av nkos uas tsis muaj qhov ntom ntom, thiab CMC nrog cov viscosity tsawg thiab qib siab ntawm kev hloov pauv yog tsim rau cov av nkos uas muaj qhov ntom ntom. Kev xaiv ntawm CMC yuav tsum txiav txim siab raws li cov xwm txheej sib txawv xws li hom av nkos, cheeb tsam, thiab qhov tob tob.
Daim ntawv thov tseem ceeb: MB-CMC3 plays lub luag hauj lwm ntawm lifting thiab txo dej poob thiab viscosity raising nyob rau hauv drilling kua, cementing kua thiab fracturing kua, thiaj li mus cuag lub zog ntawm kev tiv thaiv phab ntsa, nqa cuttings, tiv thaiv laum ntsis, tiv thaiv av nkos thiab nce. drilling ceev. Ntxiv nws ncaj qha los yog ua rau hauv cov kua nplaum thiab ntxiv rau hauv av, ntxiv 0.1-0.3% rau cov dej tshiab slurry, thiab ntxiv 0.5-0.8% rau cov dej ntsev slurry.
2. Kev siv CMC hauv kev lag luam txheej
Lub hom phiaj tseem ceeb:
Raws li lub stabilizer, nws tuaj yeem tiv thaiv cov txheej txheem los ntawm kev sib cais vim qhov hloov pauv ntawm qhov kub thiab txias.
Raws li lub tackifier, nws tuaj yeem ua rau lub xeev ntawm cov txheej txheej, ua tiav qhov zoo tshaj plaws cia thiab kev tsim kho viscosity, thiab zam kev delamination loj thaum lub sijhawm khaws cia.
Tiv thaiv drips thiab sags thaum siv.
ST, SR series instant CMC tuaj yeem yaj tag nrho hauv 30 feeb, ua kom pom tseeb, pob tshab, zoo li cov tshuaj colloidal, tsis tas yuav ntub dej ntev thiab muaj zog nplawm.
Txheej qib CMC technical indicators, As

Nyob rau hauv cov txheej txheem ntau lawm, nws yog siv rau hauv lub cev ceramic, glaze slurry thiab luam ntawv los txhim kho lub zog flexural ntawm lub cev thiab txhim kho kev ruaj ntseg ntawm glaze slurry.
4. Kev siv CMC hauv kev lag luam ntxhua khaub ncaws
Detergent qib MB-CMC3: siv rau hauv cov tshuaj detergents los tiv thaiv cov av los ntawm kev rov ua dua. Lub hauv paus ntsiab lus yog tias muaj kev sib koom ua ke electrostatic repulsion ntawm cov av tsis zoo thiab them nyiaj CMC molecules adsorbed ntawm cov ntaub. Tsis tas li ntawd, CMC kuj tseem tuaj yeem ua kom tuab cov tshuaj ntxuav slurry los yog xab npum thiab txhim kho cov qauv ntawm cov khoom sib xyaw.
5. Kev siv CMC hauv kev lag luam tshuaj txhuam hniav niaj hnub
Daim ntawv thov tseem ceeb: MB-CMC3 feem ntau raug tshem tawm hauv cov tshuaj niaj hnub, tiv thaiv cov impurities los ntawm kev rov ua dua tshiab, tswj cov dej noo, ruaj khov, thiab thickening. Nws muaj qhov zoo ntawm kev tawg sai thiab yooj yim siv. Qhov sib ntxiv yog 0.3% -1.0%. Cov tshuaj txhuam hniav feem ntau plays lub luag hauj lwm ntawm shaping thiab bonding. Los ntawm nws txoj kev sib raug zoo zoo, cov tshuaj txhuam hniav tseem ruaj khov thiab tsis cais dej. Feem ntau, cov tshuaj pom zoo yog 0.5-1.5%.
Rau, qhov ruaj khov ntawm CMC kua nplaum viscosity dhau sijhawm, cov lus qhia rau kev siv
1. Vim lub siab molecular hnyav ntawm cov khoom no, thaum npaj MB-CMC3 kua nplaum, lub sij hawm dissolution yog li ntawm ib nrab ib teev ntev dua li ntawm CMC zoo tib yam;
2. Vim lub siab viscosity ntawm cov kua nplaum saum toj no 1.2%, nws tsis tsim nyog siv cov concentration ntawm ntau tshaj 1.2% thaum CMC glued. Feem ntau, nws yog qhov tsim nyog los xaiv cov kua nplaum nrog qhov concentration ntawm li 1.0%;
3. Hauv kev xaiv qhov sib ntxiv ntawm CMC, nws yuav tsum tau txiav txim siab raws li hom graphite, thaj chaw tshwj xeeb thiab tus nqi ntawm cov pa roj carbon dub (tus neeg sawv cev) xa mus, thiab qhov sib ntxiv ntawm qhov sib piv yog 0.5% ^ 1.0%;
4. Lub viscosity ntawm slurry yog tswj ntawm txog 2500mPa.s, smoothing thiab leveling ntawm slurry yuav zoo dua, uas yog conducive rau lub uniformity ntawm txheej.
Xya, cov khoom nta thiab qhov zoo
1. Nws muaj qhov hnyav molecular, uas tuaj yeem txo qis CMC ntxiv, thiab tib lub sijhawm ua kom cov viscosity thiab stability ntawm slurry;
2. Tus nqi ntawm CMC ntxiv rau hauv cov mis yog txo los ntawm li 1%, uas tuaj yeem ua rau cov ntsiab lus ntawm cov khoom muaj txiaj ntsig thiab nce tus nqi tsim nyog ntawm cov khoom muaj peev xwm;
