siv
Acrylamide yog ib qho tseem ceeb thiab yooj yim tshaj plaws ntawm acrylamide series.Nws yog dav siv los ua raw khoom rau cov organic synthesis thiab cov ntaub ntawv polymer.Cov polymer yog soluble hauv dej, yog li nws yog siv los tsim flocculant rau kev kho dej, tshwj xeeb tshaj yog rau flocculation ntawm protein thiab starch hauv dej.Ntxiv nrog rau flocculation, muaj thickening, shear resistance, tsis kam txo, dispersion thiab lwm yam khoom zoo heev.Thaum siv los hloov kho av, nws tuaj yeem ua rau cov dej permeability thiab noo noo khaws cov av;Siv los ua daim ntawv muab tub lim, tuaj yeem ua kom muaj zog ntawm daim ntawv, tsis yog hmoov txhuv nplej siab, dej soluble ammonia resin;Siv los ua cov tshuaj grouting tus neeg sawv cev, siv nyob rau hauv civil engineering qhov excavation, roj zoo drilling, mine thiab dam engineering plugging;Siv ua fiber ntau modifier, tuaj yeem txhim kho lub cev ntawm cov khoom siv hluavtaws;Siv los ua ib qho tshuaj tiv thaiv, tuaj yeem siv rau cov khoom siv hauv av anticorrosion;Kuj tseem siv tau rau hauv kev lag luam khoom noj khoom haus additives, pigment dispersant, luam ntawv thiab dyeing muab tshuaj txhuam.Nrog phenolic resin tov, tuaj yeem ua rau iav fiber ntau nplaum, thiab roj hmab ua ke tuaj yeem ua rau cov nplaum nplaum nplaum.Ntau cov khoom siv hluavtaws tuaj yeem npaj tau los ntawm polymerization nrog vinyl acetate, styrene, vinyl chloride, acrylonitrile thiab lwm yam monomers.Cov khoom no kuj tseem siv tau ua tshuaj, tshuaj tua kab, zas xim, pleev xim rau cov ntaub ntawv raw
pob thiab thauj
B. Cov khoom no tuaj yeem siv tau, 20KG, hnab.
C. Khaws ntim rau hauv qhov chaw txias, qhuav thiab qhov cua nyob hauv tsev.Cov thawv ntim khoom yuav tsum tau muab kaw kom nruj tom qab siv txhua zaus ua ntej siv.
D. Cov khoom no yuav tsum raug kaw kom zoo thaum lub sijhawm thauj mus los kom tsis txhob ya raws, muaj zog alkali thiab acid, nag thiab lwm yam impurities los ntawm kev sib xyaw.
