PAC HV & PAC LV -} xov xwm

PAC, luv luv rau polyanionic cellulose, yog lub cellulose derivative feem ntau siv los ua kev ntxiv hauv cov roj drilling kua. Raws li lawv viscosity, pac yog categorized ua ob hom:Pac lv(Tsis viscosity) thiabPAC HV(Siab viscosity).

Cov hauv qab no yog qhov sib piv ntawm cov qauv sib txawv ntawmPAC LV (qis viscosity polyanionic cellulose)thiabPAC HV (siab viscosity polyanionic cellulose), raws li lawv cov haujlwm, cov khoom siv dag zog, thiab cov ntawv teev cov xwm txheej hauv cov dej ntws:

tus yam ntxwv	PAC LV (tsis viscosity tsawg)	PAC HV (siab viscosity)
Viscosity kev ua tau zoo	Tsis viscosity(Pom meej viscosity tsawg dua los yog sib luag rau 40 mpa a) Tsom rau kev txo cov kua dej ploj thiab muaj cov nyhuv me me ntawm slurry thickening.	Siab viscosity(pom tseeb viscosity ntau dua los yog sib npaug rau 50 MPAN nkaus) Nrog dual lub zog ntawm viscosity nce thiab ua kom muaj kev txo qis
Cov yam ntxwv	▶ tau txo cov kua dej txo qis (API kua poob qis dua lossis sib npaug rau 16 ml) ▶ txhim kho cov av nkos khoom qab zib zoo Hlawv ntsev thiab calcium ua	Im Cov kua dej ua tau zoo txo (API kua poob qis dua lossis sib npaug rau 23ml) ▶ Txawm nce viscosity thiab lub zog shear ▶ Powerfully txo cov kua poob ▶ tshem tawm cov cuttings thiab ntxuav kom zoo
Ntsev thiab calcium ua	⭐⭐⭐⭐ (Muaj zog ruaj khov nyob rau hauv siab ntsev dej / calcium kis)	⭐⭐⭐ (me ntsis tsis muaj zog nyob rau hauv ntsev tsis kam, tab sis tseem ruaj khov nyob rau ntawm qhov kub siab)
Siv tau cov kua dej ua kom drilling siv tau	▶ brine / saturated brine system ▶ Siab -} qhov ceev ntom tshuab kua ▶ Xwm Scenario xav tau cov viscosity thiab siab shear	Ef Freshwater / qis salinity Systems Willscks zoo yuav tsum muaj viscosity siab ▶ Cov ntu uas txiav kev ua tiav yog qhov nyuaj
Pom zoo muab tshuaj ntau	0.3% -1.0% (Qhov nyiaj tsawg dua kom ua tiav cov txiaj ntsig zoo hauv cov kua dej tsis txo)	0.5%–1.5% (a higher dosage is required to ensure viscosity-increasing effect)
Muaj Qhov Ntsuas Kub Ntau	Tsawg dua los yog sib npaug rau 150℃(ruaj khov ua tau zoo ntawm qhov kub siab)	Tsawg dua los yog sib npaug rau 150℃(viscosity yuav txo qis thaum muaj kub)
Molecular qauv yam ntxwv	Short chain molecules, high℃of substitution (>0.90), Kev faib tawm sai sai thiab kev sib cais	Ntev saw molecules, Qib ntawm kev hloov pauv ntau dua lossis sib npaug rau 0.90 yuav tsum tau ua kom nruj thiab yaj mentolved
Ua hauj lwm	★★★★☆ (Tsawg noj tshuaj + muaj zog anti - cov pa phem → muaj tus nqi qis dua)	★★★☆☆ (Kev siv yog qhov loj; lwm tus neeg kho mob yuav tsum muaj rau cov qhov dej tob)
