Polyanionic cellulose (PAC) cov lus qhia
I). Taw qhia: PAC yog tsim los ntawm tej paj rwb luv fibers los ntawm ib tug series txoj kev tshua tshuaj nyob rau hauv qhov system derivatives cellulose ether, yog ib qho tseem ceeb anionic cellulose water-soluble ether. Nrog "peb siab thiab qis ib" nta: stability kub, kub kuj, muaj kua qaub ntsev, tsis pab.
2), PAC yooj yim zog:
Lub zog: Zog yog dawb, dawb los sis lub teeb daj hmoov los granules, cov-mob toxic, ntxhiab, hygroscopic, soluble hauv cov dej txias thiab dej kub.
3), tshuaj zog yav tom ntej:
1. cov teeb siab muab: muab tus nqi 0.85-1.4.
2. Thaum tshav kub kub stability: dej hauv qab 80 ℃ ruaj khov ntawv, thaum tus kub yuav muab tso tawm kom pom mus txog ze ntawm 150 ℃ tej viscosity.
3. acid ntsev: PH nqi ruaj khov nyob rau hauv lub chav 3-11, yuav muaj ntaub ntawv rau ntau hom ncov qaumteb qabteb npuas hnyav.
4. zoo compatibility: lwm cellulose ethers, dej soluble nplaum, softener, cob, lwm yam tsis tau tshaj.
5. qhov zoo solubility: siv yooj yim nplawm tau tau zus neej nyob hauv cov dej txias thiab dej kub, twb nrauj tiav tag hauv dej kub ceev.
6. zoo stability: PAC tov nrog ib stability lub teeb, ntev txee neej; pwm muaj zog los tiv thaiv bacterial zog, tsis fermented.
7. qhov tsis muab: PAC vim yog siab txog qib uas muab, siab stability yam ntxwv, ib puag ncig muaj nqi me me, tiam sis feem ntau ntxiv li 0.2% li 0.6%, tshaj kom xwb lwm cellulose ethers (thaum txog CMC, etc.) 30-50%, txo tus nqi, uas muaj ib nqe advantage yooj yim dua.
8. ntsuab: PAC yog lub ntsiab raw khoom rau refined paj rwb, twb tsis muaj pharmacological ntxim rau tib neeg lawm, txoj kev ntau lawm rau ntsuab xwb.
4), PAC lub hom phiaj thiab tshwm li cas:
Polyanionic cellulose sodium ntsev (PAC) yog ib tug water-soluble organic polymer, neej yuav dej yuav tsim ib pob tshab khov kua nrog rau ib tug kawm ntawv, yuav lug siv ntau lawm muaj nyob ntau qhov chaw, ua si ib thooj zoo kawg nkaus, thooj, ruaj, ncua kev kawm tamsim, dej, emulsifying, dispersing, stabilizing cov luag hauj lwm. Roj drilling, qhov dej thiab lwm yam tej yaam num, PAC yooj yim hauv dej los drilling cov dej, nrog rau cov dej, dej hiav txwv, saturated brine, thiab lwm yam kua nruab nrog cev yuav tau mus thov, mas offshore drilling thiab tsaws tob hauv lub khib nyiab uas tsis muaj drilling, kua PAC yuav txo tau qhov nyiaj poob dej, thinning tus thickness ntawm lub ncuav mog qab zib, thiab cov nplooj ntawv muaj ib qho inhibition ntawm cov brine. Faib viscosity (HV), uas tsis muaj viscosity (LV), nruab nrab viscosity (R) 3.
5), loaded thauj thiab cia:
Cov khoom no yog ib lub hnab "ua si triple" lined nrog polyethylene zaj duab xis hnab nqa poob phaus 25kg; muab cia rau hauv ib tug laj, qhuav, chaw hliv. Nyob rau lub cia nruab nrab, nws cov solubility hauv dej, tsis txhob tej tej pob khoom, ya raws tsis rau siv.
