Polymer Coal-ntxuav Thiab Sandwashing Dej Kho Flocculant Polyacrylamide

Polyacrylamide (PAM) yog linear polymer. Raws li ib tug lubricant, ncua kev kawm ntawv tus neeg saib xyuas, av nplaum stabilizer, roj hloov chaw, kua poob additive, thiab thickener, nws tau lug siv nyob rau hauv drilling, acidification, fracturing, dej plugging, cementing, theem nrab roj rov qab, thiab tertiary roj rov qab. Nws yog ib qho tseem ceeb heev oilfield tshuaj.

Polyacrylamide muaj cov khoom flocculation zoo thiab tuaj yeem txo cov kev sib txhuam ntawm cov kua. Nws tuaj yeem muab faib ua peb hom raws li cov yam ntxwv ionic:Non-ionic polyacrylamide (NPAM), anionic polyacrylamide (APAM), thiabcationic polyacrylamide (CPAM).

Cationic polyacrylamide (CPAM) Feem ntau yog siv rau sludge dewatering hauv nroog cov dej phwj tuaj kho cov nroj tsuag, xws li cov dej cawv cawv, cov dej khib nyiab, cov dej khib nyiab, npias pov tseg, cov dej khib nyiab monosodium glutamate, qab zib cov dej khib nyiab, cov dej khib nyiab siab, dej khib nyiab, textile printing thiab dyeing wastewater, thiab lwm yam lag luam ua coagulant pab. thiab sludge dewatering agents. Tsis tas li ntawd, cationic PAM kuj tseem siv tau los ua cov tshuaj oilfield additives, xws li av nplaum los tiv thaiv cov kab mob o, thickening agents for oilfield acidification, thiab reinforcing agents for papermaking.

Anionic polyacrylamide (APAM) Feem ntau yog siv los kho cov kev tshem tawm nruab nrab feem ntau yog tsim los ntawm cov khoom tsis muaj zog. Nyob rau hauv mining, nws yog siv rau kev qhia meej ntawm cov thee ntxuav dej thiab flotation tailings, pom cov thee huv si, dewatering ntawm tailings (slag), clarification ntawm flotation tailings, thickening thiab pom ntawm concentrate, clarification ntawm poov tshuaj alkali kub tov thiab flotation ua kua, Kev nthuav dav ntawm flotation tailings ntawm fluorite thiab barite, nrog rau kev qhia meej ntawm cov dej ntsev nyoos thiab sludge dewatering rau kev ua ntsev, thiab kev kho cov phosphate ore rov qab dej. Hauv kev lag luam casting thiab hlau tsim, nws yog siv rau kev ua kom huv ntawm cov pa ntxuav thiab txheej dej hauv qhov qhib hearth furnaces, kev qhia meej ntawm cov dej khib nyiab los ntawm cov hmoov metallurgy thiab acid pickling nroj tsuag, purification ntawm electrolytes, thiab kev qhia meej ntawm electroplating pov tseg kua.

Non-ionic polyacrylamide (NPAM) tuaj yeem siv los ua tus neeg sawv cev pabcuam hauv kev lag luam textile. Thaum qee cov tshuaj ntxiv ntxiv, nws tuaj yeem tsim rau hauv cov tshuaj slurry rau textile sizing los txhim kho adhesion, permeability, thiab desizing kev ua tau zoo, ua cov ntaub los tiv thaiv zoo li qub, txo qhov sizing tus nqi, txo warping me ntsis, ntaub tshuab tawg tus nqi, thiab khib nyiab. . Tsis yog ionic polyacrylamide feem ntau yog siv los ua cov dej phwj tuaj kho, haum rau acidic suspensions, thiab haum rau siv raws li flocculant. Lub sijhawm no, PAM ua lub luag haujlwm adsorption bridging, ua rau cov khoom raug tshem tawm mus rau flocculate thiab precipitate, ua tiav lub hom phiaj ntawm cov dej huv.
