Kev piav qhia
Fkev txhais lusctswj tshuaj ntxivhloov khopolysaccharides(cov hmoov txhuv nplej siab)yog cov hmoov txhuv nplej siab ua ntej gelilating ua tau zoo, qhia cov pab pawg ua haujlwm sib txawv rau cov khoom nws tus kheej, yog li hloov pauv hom kev txav thiab cov qauv molecular ntawm pre-gelilating starch hauv cov khoom. Nrog rau resistant rau mildew, txhim khu lub zog cohesive ntawm txheej nyob rau hauv cov xwm txheej ntawm huab cua siab.
Tus qauv ntawmfkev txhais lusctswj tshuaj ntxivhloov khopolysaccharides(cov hmoov txhuv nplej siab)belongs rau carbohydrate thiab zoo ib yam li cellulose, thiab kuj yog ib qho ntawm thawj zaug siv filtration tswjua lerhauv cov dej drilling. Nws los ntawm cov nplej thiab pob kws, tsis tuaj yeem yaj rau hauv dej hauv qhov kub ntawm 50 degree,tab sistuaj yeem o yog tias qhov kub siab tshaj 55 degree mus txog rau translucently gel lossis colloidal tov.
Fkev txhais lusctswj tshuaj ntxivhloov khopolysaccharides(cov hmoov txhuv nplej siab)tuaj yeem tsis tsuas yog txo qhov pom tab sis kuj nce viscosity ntawm lim thiab coagulation stability, thiab tuaj yeem siv rau hauv dej tshiab, dej hiav txwv thiab dej saturated drilling kua.
Hloov cov hmoov txhuv nplej siabyooj yim rau ferment thaum siv nyob rau hauv qis salinity los yog pH (nws muaj qhov zoo tshaj plaws ua nyob rau hauv siab salinity thiab pH tus nqi siab tshaj 11.5). Thiab yooj yim rau degrade nyob rau hauv kub siab tshaj 120 degree
Daim ntawv thov
• Kub tiv taus mus txog 120 degree
• Tshwj xeeb tshaj yog haum rau cov kab mob uas tsis yog-dispersed ntawm ROP siab
• Inhibit shale dispersion
• Tsis cuam tshuam los ntawm salinity
• Cov khoom siv acid-soluble
Qhov zoo
• Ua tau zoo nrog ceev ceev drilling tshuab tsis-dispersed;
• Pab txo cov av nplaum tawg;
• Not adversely cuam tshuam los ntawm salinity thiab plays lub luag hauj lwm nyob rau hauv ntau yam dej chemistry.
