Polyacrylamide (PAM)
Polyacrylamide (PAM) yog cov dej-soluble polymer tsim los ntawm polymerization ntawm acrylamide. Cov tsos yog dawb granules los yog hmoov. Thiab nws yog soluble hauv dej thiab insoluble hauv organic teeb meem. PAM yog cov khoom siv hluavtaws tuaj yeem hloov kho rau ntau yam kev siv. Yog li PAM tshuaj tuaj yeem siv rau roj av kev tshawb nrhiav.water kho, textile, papermaking, ntxhia ua, tshuaj, kev ua liaj ua teb thiab lwm yam lag luam. lwm.
Kev siv tseem ceeb ntawm Polyacrylamide hauv kev kho dej
Daim ntawv thov hauv roj rov qab
Polyacrylamide yog ib tug multifunctional oilfield tshuaj kho neeg sawv cev lug siv nyob rau hauv drilling, cementing, tiav, workover, fracturing, acidification, dej txhaj, dej plugging thiab profile tswj, tertiary roj rov qab thiab lwm yam teb, tshwj xeeb tshaj yog nyob rau hauv drilling, dej plugging thiab profile tswj, tertiary roj rov qab thiab lwm yam teb. Polyacrylamide aqueous tov muaj viscosity siab, zoo thickening, flocculation, thiab rheological kev tswj cov teebmeem, thiab yog siv los ua ib tug displacement tus neeg saib xyuas thiab drilling kua regulator nyob rau hauv roj av tshawb nrhiav.
Daim ntawv thov ntawm polyacrylamide hauv kev lag luam papermaking feem ntau suav nrog ob yam: ua ntej, kev txhim kho tus nqi khaws cia ntawm cov fillers thiab pigments, txo cov khoom siv raw thiab ib puag ncig muaj kuab paug; Qhov thib ob yog los txhim kho lub zog ntawm daim ntawv. Ntxiv polyacrylamide rau daim ntawv tuaj yeem txhim kho tus nqi khaws cia ntawm cov fibers zoo thiab muab tub lim rau ntawm lub mesh, ua kom lub cev qhuav dej ntawm daim ntawv, thiab tsim cov flocs tuaj yeem ua rau cov dej hauv cov ntaub so ntswg yooj yim lim tawm, txo qhov poob ntawm cov fibers. dej dawb, txo cov pa phem ib puag ncig, thiab txhim kho qhov pom thiab pom kev ua haujlwm ntawm cov khoom siv sedimentation.
Polyacrylamide gel tuaj yeem siv los ua tus neeg saib xyuas tsis yog prothrombin granulating, kev phais mob, cov khoom siv tiv thaiv lub lens, microcapsule txheej txheej, thiab tuaj yeem siv los tsim cov khoom zoo hemostatic, cov ntaub so ntswg huv thiab cov menyuam yaus cov ntaub qhwv. Polyacrylamide nrog qhov loj me ntawm ntau pua mus rau kaum tawm microns tuaj yeem siv los ua cov khoom ntim chromatographic, xws li gel kem packing, uas tuaj yeem cais cov proteins kheej kheej xws li cytochrome. Nws tseem tuaj yeem ntxiv dilute thiab concentrates cov proteins.
Hauv kev lag luam khoom noj khoom haus, nws yog siv rau kev qhia meej ntawm cov kua txiv hmab txiv ntoo thiab cov floatation ntawm phosphorus phosphorus hauv kev tsim cov qab zib qab zib thiab beet qab zib. Lub flocculation thiab qhia meej ntawm enzyme fermentation broth kuj tseem siv tau rau kev rov qab los ntawm cov protein pub, nrog kev ruaj khov thiab kev ua haujlwm zoo. Nws kuj tseem tuaj yeem siv rau cov khoom siv hluavtaws, cov khoom siv rau kev tsim vaj tsev, dej thaiv, kev lag luam hauv tsev, kev txhim kho cement zoo, nplaum rau kev tsim kho kev lag luam, sib koom ua ke thiab kho cov neeg ua haujlwm, dej thaiv cov neeg ua haujlwm, kev txhim kho av, kev lag luam electroplating, luam ntawv thiab dyeing kev lag luam, thiab lwm yam.
