Polyacrylamide, hu ua PAM , yog lub siab molecular-hnyav polymer. Vim nws cov qauv tshuaj tshwj xeeb, PAM tau siv dav hauv ntau qhov kev lag luam. Hauv cov teb xws li kev kho dej, roj av, mining thiab papermaking, PAM yog siv los ua cov flocculant zoo los txhim kho cov dej zoo, ua kom cov mining efficiency, thiab txhim kho cov ntawv zoo. Txawm hais tias PAM muaj cov dej solubility tsawg, los ntawm cov txheej txheem kev sib cais tshwj xeeb, peb tuaj yeem yaj nws hauv dej kom ua haujlwm tau zoo hauv ntau daim ntawv thov kev lag luam. Cov neeg ua haujlwm yuav tsum ua tib zoo saib xyuas nws cov lus qhia tshwj xeeb ua ntej siv. thiab kev ceev faj kom paub meej cov khoom siv tau zoo thiab kev nyab xeeb ntawm tus kheej.
Cov tsos mob thiab tshuaj lom neeg ntawm Polyacrylamide
PAM feem ntau yog muag hauv daim ntawv hmoov lossis emulsion. Pure PAM hmoov yog dawb rau lub teeb daj zoo hmoov uas yog me ntsis hygroscopic. Vim nws qhov hnyav molecular thiab viscosity, PAM dissolves maj mam hauv dej. Txoj kev sib cais tshwj xeeb yuav tsum tau siv thaum yaj PAM kom ntseeg tau tias nws tau yaj tag nrho hauv dej.
Yuav siv PAM li cas
Thaum siv PAM, koj yuav tsum xub xaiv ib qhotsim nyogFlocculantnroghaum specifications raws li cov kev thov scenarios thiab xav tau kev pab. Qhov thib ob, nws yog ib qho tsim nyog yuav tsum tau ua qhov kev sim hub nrog cov qauv dej thiab cov flocculant. Thaum lub sij hawm flocculation txheej txheem, stirring ceev thiab sij hawm yuav tsum tau tswj kom tau qhov zoo tshaj plaws flocculation nyhuv. Nyob rau tib lub sijhawm, qhov ntau npaum li cas ntawm flocculant yuav tsum tau kuaj xyuas thiab kho kom tsis tu ncua kom ntseeg tau tias cov dej zoo thiab cov mining thiab lwm cov txheej txheem tsis ua raws li qhov yuav tsum tau ua. Tsis tas li ntawd, ua tib zoo saib xyuas cov tshuaj tiv thaiv ntawm flocculant thaum siv, thiab siv sij hawm ntsuas los kho yog tias muaj kev txawv txav tshwm sim.
Nws yuav siv sij hawm ntev npaum li cas kom tiav tom qab dissolving?
Thaum PAM tau yaj tag, nws lub sijhawm ua haujlwm feem ntau cuam tshuam los ntawm qhov kub thiab txias. Nyob rau hauv chav tsev kub, lub sij hawm siv tau ntawm cov tshuaj PAM feem ntau yog 3-7 hnub nyob ntawm seb hom PAM thiab qhov concentration ntawm cov tshuaj. Thiab nws yog qhov zoo tshaj plaws siv hauv 24-48 teev. PAM cov tshuaj yuav poob kev ua haujlwm tsis pub dhau ob peb hnub yog tias raug tshav ntuj rau lub sijhawm ntev. Qhov no yog vim hais tias, nyob rau hauv qhov kev txiav txim ntawm tshav ntuj, PAM molecular chains yuav tawg, ua rau txo qis ntawm nws cov nyhuv flocculation. Yog li ntawd, cov tshuaj yaj yeeb PAM yuav tsum tau muab cia rau hauv qhov chaw txias thiab siv sai li sai tau.
Cov kev ceev faj
Koj yuav tsum tau xyuam xim rau cov hauv qab no thaum siv PAM:
Teeb meem kev nyab xeeb: Thaum tuav PAM, cov cuab yeej tiv thaiv tus kheej tsim nyog yuav tsum tau hnav, xws li tshuaj tiv thaiv tsom iav, lub tsho tiv no, thiab hnab looj tes tiv thaiv tshuaj. Nyob rau tib lub sijhawm, zam kev sib cuag ntawm daim tawv nqaij ncaj qha nrog PAM hmoov lossis tshuaj.
Kev Txhaum Cai thiab Txau: PAM yuav nplua heev thaum ua ke nrog dej, yog li siv kev ceev faj ntxiv los tiv thaiv PAM hmoov los ntawm kev nchuav los yog oversprayed rau hauv av. Yog hais tias nchuav los yog txau, nws yuav ua rau cov av nplaum thiab ua rau muaj kev phom sij rau cov neeg ua haujlwm nyab xeeb.
Ntxuav thiab tiv tauj: Yog tias koj cov khaub ncaws lossis tawv nqaij tau txais PAM hmoov lossis tshuaj, tsis txhob yaug ncaj qha nrog dej. Maj mam so PAM hmoov nrog cov phuam qhuav yog txoj kev nyab xeeb tshaj plaws.
Cia thiab Ncua Sijhawm: Granular PAM yuav tsum muab khaws cia rau hauv lub thawv ntawv pov thawj kom deb ntawm tshav ntuj thiab huab cua kom tswj tau nws cov txiaj ntsig. Kev raug tshav ntuj ntev ntev thiab huab cua tuaj yeem ua rau cov khoom lag luam poob lossis txawm tias tsis zoo. Yog li ntawd, cov txheej txheem ntim khoom tsim nyog yuav tsum raug xaiv los ua kom cov khoom zoo thiab ruaj khov. Yog tias cov khoom raug pom tias tsis raug lossis tas sijhawm, nws yuav tsum tau ua raws sijhawm thiab hloov nrog cov khoom tshiab kom tsis txhob cuam tshuam rau kev siv ib txwm muaj thiab kev nyab xeeb. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them nyiaj rau kev tshuaj xyuas lub txee lub neej ntawm cov khoom thiab lees paub nws cov txiaj ntsig ua ntej siv los ntawm cov kev ntsuam xyuas cuam tshuam lossis kev tshuaj xyuas kom ntseeg tau tias nws ua tau raws li cov txheej txheem.
