Polyanionic Cellulose High Viscosity (PAC HV)

High viscosity polyanionic cellulose (PAC-HV) yog ib hom cellulose derivative uas yog dav siv los ua ib qho viscosifier thiab kua tsis tswj additive nyob rau hauv ntau yam industries, tshwj xeeb tshaj yog nyob rau hauv drilling thiab tiav kua rau roj thiab roj kev tshawb fawb. Nov yog qhov kev piav qhia ntawm PAC-HV:

1. Muaj pes tsawg leeg: PAC-HV yog muab los ntawm ntuj cellulose los ntawm kev hloov tshuaj lom neeg los qhia cov carboxymethyl pawg thiab txhim kho nws cov solubility hauv dej. Qib ntawm kev hloov pauv thiab qhov hnyav molecular txiav txim siab viscosity thiab kev ua haujlwm ntawm PAC-HV.

2. Kev ua haujlwm:

• Viscosifier: PAC-HV imparts siab viscosity rau aqueous daws, ua rau nws zoo rau thickening drilling kua thiab txhim kho lawv nqa peev xwm rau drilled cuttings.
• Fluid Loss Control: PAC-HV tsim cov ncuav mog qab zib nyias, impermeable lim rau ntawm phab ntsa borehole, txo cov kua dej poob rau hauv kev tsim thiab tswj kev ruaj ntseg zoo.
• Rheology Modifier: PAC-HV cuam tshuam tus cwj pwm ntws thiab cov khoom siv rheological ntawm cov kua dej drilling, txhim kho kev ncua ntawm cov khib nyiab thiab txo qis.

3. Kev siv:

• Roj thiab Roj Drilling: PAC-HV yog siv dav hauv cov dej hauv dej drilling rau ob qho tib si onshore thiab offshore drilling kev ua haujlwm. Nws pab tswj kev ruaj ntseg zoo, tiv thaiv kev tsim kev puas tsuaj, thiab pab txhawb kev ua haujlwm zoo drilling.
• Kev tsim kho: PAC-HV yog ua haujlwm los ua cov thickener thiab dej tuav tus neeg sawv cev hauv cov cementitious formulations xws li grouts, slurries, thiab mortars siv hauv kev tsim kho.
• Pharmaceuticals: Nyob rau hauv cov tshuaj formulations, PAC-HV pab raws li ib tug binder, disintegrant, thiab tswj-tso tus neeg saib xyuas nyob rau hauv cov ntsiav tshuaj thiab tshuaj ntsiav formulations.

4. Khoom:

• High Viscosity: PAC-HV nthuav tawm cov viscosity siab hauv cov tshuaj, muab cov khoom ua kom tuab zoo heev txawm tias muaj qhov tsawg.
• Dej Solubility: PAC-HV yog yooj yim soluble nyob rau hauv dej, tso cai rau ib qho yooj yim kev koom ua ke rau hauv aqueous systems tsis tas yuav tsum tau ntxiv cov kuab tshuaj los yog dispersants.
• Thermal Stability: PAC-HV tswj nws cov viscosity thiab kev ua tau zoo ntawm ntau yam kub uas tau ntsib hauv drilling thiab lwm yam kev siv hauv kev lag luam.
• Salt Tolerance: PAC-HV qhia tau hais tias muaj kev sib raug zoo nrog cov ntsev thiab cov ntsev ntau hauv cov roj av.

5. Zoo thiab Specifications:

• PAC-HV cov khoom lag luam muaj nyob hauv ntau qib thiab cov lus qhia tshwj xeeb raws li cov ntawv thov tshwj xeeb thiab cov kev xav tau ua haujlwm.
• Kev tswj xyuas kev ua tau zoo ua kom zoo sib xws thiab ua raws li cov qauv kev lag luam, suav nrog API (American Petroleum Institute) cov lus qhia tshwj xeeb rau cov kua dej ntxiv.

Hauv cov ntsiab lus, PAC-HV yog cov khoom siv ntau yam thiab muaj txiaj ntsig zoo nrog cov viscosity siab, tswj cov dej tsis zoo, thiab cov khoom siv rheological, ua rau nws tseem ceeb rau ntau yam kev lag luam, tshwj xeeb hauv kev ua haujlwm roj thiab roj. Nws txoj kev ntseeg siab, kev ua tau zoo, thiab kev sib raug zoo nrog lwm cov khoom siv ntxiv ua rau nws siv dav hauv qhov nyuaj drilling ib puag ncig.
