Carboxymethyl Cellulose (CMC) raws li tus Thickener tau lug siv kev lag luam, roj Drilling av nkos kho yog ib qho tseem ceeb dab tsi rau Drilling.

Carboxymethyl cellulose (CMC) raws li tus thickener tau lug siv kev lag luam, roj drilling av nkos kho yog ib qho tseem ceeb dab tsi rau drilling thiab zoo tiav thiab cementing, etc., ntawm thooj, kawg, gelling, suspending, thiab hais txog. Los expanding teb ncua ntawm kev tshawb kawm roj drilling thiab ua tej lub qhov tob nruab nrab ntawm lub CMC zoo raws lus ntau, kheej CMC ua ib siab viscosity, ntsev kam rau ua kuj mus kuj calcium thiab kub. Nyob rau hauv kev txhim kho kev CMC txawv teb chaws, uas siv cov crushed, cellulose sealing nrog nitrogen roj, kom tus piv kuab tshuaj, sib ntxiv ntawm antioxidants thiab lwm txoj kev, after lub teeb siab polymerization, kawm ntawv siab uas muab thiab ua ib siab uniformity kev tis ntawm substituents lub hom phiaj, xws li hu ua CMC upgrading polyanionic cellulose (APc) tau kuj zoo
Ntsev kuj, calcium uas kuj, kuj kub thiab siab viscosity ntawm. Tuam Tshoj muaj nrhiav tau cov kev kawm nyob rau hauv qhov chaw kho mob ua ntej ntau lawm, tiam sis txwv rau cov kev mob ntawm cov khoom uas twb muaj lawm, feem ntau ntawm cov roj CMC cog ntau lawm qeb thiab cov khoom zoo uas muaj ntsis zoo ib yam khoom txawv teb chaws tseem zoo ib yam loj. MCC yam zoo ntawm cov khoom uas muaj ntau, no Tshooj attempts paj ntaub micro-crosslinked sodium tetraborate, kev tshawb fawb crosslinking mechanism thiab ntsev, kua qaub muab cov nyhuv rau lub CMC thiab cov viscosity, cov tis los luj, mus rau hauv lub cev uas khov heev ntsev kam rau ua CMC muab theoretical thiab seb puas yog tiag.
