Roj Well Fluid Additive Drilling Mud Chemical Suppliers Anionic Qhuav Hmoov Zoo Pam Polyacrylamide Flocculants

polyacrylamide (abbreviated PAM los yog PAAM), nrog rau cov mis -[CH2CH]nCONH2-, yog ib tug polymer tsim los ntawm cov polymerization ntawm acrylamide monomers. Raws li ib tug lubricant, ncua kev kawm ntawv tus neeg saib xyuas, av nplaum stabilizer, roj hloov chaw, dej poob reducer thiab thickening tus neeg saib xyuas, polyacrylamide tau lug siv nyob rau hauv drilling, acidification, fracturing, dej plugging, cementing, theem nrab thiab tertiary roj rov qab, thiab yog ib tug tseem ceeb heev oilfield. tshuaj.

Polyacrylamides yog cais raws li non-ionic (NPAM), cationic (CPAM), anionic (APAM) thiab Amphionic (Amphionic PAM).

Cov anionic polyacrylamide feem ntau yog siv los ua cov av hloov kho rau thaj av cog thiab ua tus neeg saib xyuas qhov chaw yaig. Cov tshuaj ionic xws li ntsev ua rau cov polyacrylamide tso nws cov khoom nqus dej.

Ntawm cov organic polymer flocculants, anionic polyacrylamide (APAM) muaj keeb kwm ntev, cov cuab yeej paub tab thiab siv dav, yog li nws kuj tau them nyiaj ntau dua. Qhov zoo ntawm anionic polyacrylamide yog: tus nqi qis dua cationic polyacrylamide thiab amphoteric polyacrylamide, cov nyhuv flocculation yog qhov zoo, thiab cov txheej txheem yog mature.

Flocculation nyhuv ntawm PAM cov khoom hauv kev kho dej khib nyiab

Raws li cov khoom ntawm kev tshem tawm cov teeb meem, concentration thiab flocculation kev ua tau zoo ntawm polyacrylamide, nag lossis daus tuaj yeem muab faib ua: ntuj nag lossis daus, flocculation nag lossis daus hauv cheeb tsam. Qhov concentration ntawm cov khoom raug tshem tawm hauv cheeb tsam nag lossis daus yog siab dua (ntau dua 5000mg / L), thiab kev sib haum xeeb ntawm cov khoom raug cuam tshuam los ntawm lwm cov khoom nyob ib puag ncig, thiab cov txheeb ze ntawm cov khoom tsis hloov pauv, ua rau tag nrho cov dab dej, thiab muaj qhov tseeb. av nkos-dej interface ntawm lawv thiab cov dej ntshiab. Regional sedimentation tshwm sim nyob rau hauv ob qho tib si theem nrab sedimentation tank thiab sludge thickening tank.

Daim ntawv thov ntawm polyacrylamide:

1. Polyacrylamide yog homopolymer ntawm acrylamide lossis polymer copolymerized nrog lwm cov monomers, thiab polyacrylamide (PAM) yog ib qho ntawm cov khoom siv ntau hom dej-soluble polymers.

2. Polyacrylamide yog dav siv hauv kev siv roj, ua ntawv, kho dej, textile, tshuaj, kev ua liaj ua teb thiab lwm yam lag luam. Raws li kev txheeb cais, 37 feem pua ​​​​ntawm lub ntiaj teb tag nrho cov khoom siv polyacrylamide (PAM) yog siv rau kev kho dej khib nyiab, 27 feem pua ​​​​rau kev lag luam roj av, thiab 18 feem pua ​​​​rau kev lag luam ntawv.

3. Polyacrylamide muaj thermal stability zoo, yooj yim rau yaj hauv dej txias, viscosity thiab concentration ntawm nws cov kua aqueous yog kwv yees li logarithmic (uas yog, linear kev sib raug zoo), siab txheeb ze molecular hnyav thiab ultra-siab txheeb ze molecular hnyav (ntau tshaj 2000 ×. 10) polyacrylamide (PAM) muaj viscosity siab, thiab nws cov tshuaj aqueous muaj qhov ua tau zoo rau electrolyte.

Lub hauv paus ntsiab lus ntawm kev ua ntawm polyacrylamide:

1. Polyacrylamide molecular saw ntev heev, yog li nws tuaj yeem txuas ntawm ob qhov sib txuas, ua kom nrawm ntawm cov khoom sib txuas, yog ib qho zoo flocculant. Polyacrylamide thiab nws cov derivatives yog tsim los ntawm dawb radical polymerization ntawm acrylamide. Raws li lub xeev dispersion ntawm lub monomer nyob rau hauv nruab nrab, cov txheej txheem polymerization yuav muab faib ua bulk polymerization, tov polymerization, ncua kev kawm ntawv polymerization thiab emulsion polymerization.

2. Raws li lub xeev dissolution ntawm monomer thiab polymer, nws yuav muab faib ua homogeneous polymerization thiab heterogeneous polymerization. Cov khoom siv polyacrylamide muaj nyob rau hauv peb hom tshuaj: aqueous colloid, hmoov thiab emulsion. Polyacrylamide yog polymerized los ntawm acrylamide, thiab nws cov saw tseem ceeb molecular muaj ntau pawg sab nraud - amide pawg, uas muaj cov tshuaj lom neeg ua haujlwm siab thiab tuaj yeem cuam tshuam nrog ntau yam sib txuas los tsim ntau cov khoom siv polyacrylamide.

3. Cov pab pawg amide tuaj yeem tsim muaj zog hydrogen daim ntawv cog lus nrog ntau yam kev sib txuas tshwj xeeb, yog li nws tsis tsuas yog muaj flocculation, thickening, deg kev ua haujlwm thiab lwm yam khoom, tab sis kuj tuaj yeem hloov mus rau hauv cov polymer uas muaj carboxyl pawg los ntawm nws cov amide hydrolysis, ua anionic polyacrylamide, polyacrylamide thiab formaldehyde cov tshuaj tiv thaiv los tsim hydroxymethylated polyacrylamide, yog ib qho tseem ceeb cross-linked monomer.

Cationic polyacrylamide (CPAM)Feem ntau yog siv rau hauv cov txheej txheem kev ua kua dej sib cais, suav nrog sedimentation, kev qhia meej, concentration thiab sludge dehydration thiab lwm yam txheej txheem, cov kev lag luam tseem ceeb yog: kev kho dej hauv nroog, kev lag luam ntawv, kev lag luam ua zaub mov, kev lag luam petrochemical, metallurgy kev lag luam, kev lag luam ntxhia. , dyeing kev lag luam thiab kev lag luam qab zib thiab ntau yam kev kho dej khib nyiab. Polyacrylamide (CPAM) yog siv rau hauv sludge nag lossis daus thiab sludge dewatering ntawm cov dej phwj hauv nroog, nqaij, nqaij qaib thiab zaub mov ua dej khib nyiab.

Anionic polyacrylamide (APAM)yog cov dej-soluble polymer, feem ntau yog siv nyob rau hauv ntau yam industrial wastewater flocculation kev daws teeb meem, nag lossis daus thiab kev kho kom meej, xws li steel zeb khib nyiab, electroplating cog khib nyiab, metallurgical khib nyiab, thee ntxuav dej khib nyiab thiab lwm yam dej phwj tuaj kho, sludge dehydration. Kuj tseem siv tau rau kev haus dej kom meej meej thiab kev kho kom huv.

Nonionic polyacrylamideyog dej-soluble polymer lossis polyelectrolyte. Vim tias nws cov saw hlau molecular muaj qee yam ntawm cov pawg polar, nws tuaj yeem nqus cov khoom uas raug tshem tawm hauv dej, txuas cov khoom los yog condense cov khoom los ntawm kev them nyiaj nruab nrab los tsim cov flocculates loj. Yog li ntawd, nws muaj peev xwm ua kom lub zog ntawm cov khoom nyob rau hauv lub ncua kev kawm ntawv, muaj ib tug heev yooj yim acceleration ntawm kev daws teeb meem, txhawb kev pom thiab lwm yam teebmeem. Nws yog tsuas yog siv rau flocculation, sedimentation thiab clarification ntawm ntau yam dej khib nyiab. Xws li daim ntawv thiab cov dej khib nyiab kho, kev ua cov ntxhia thiab cov txheej txheem hlau smelting cov dej khib nyiab, steel cog thiab pob zeb ua cov nroj tsuag dej khib nyiab.
