PAM yekurapwa kweMvura
Nhanganyaya
PAM (Polyacrylamide) imhando yepolymer inoshandiswa mune zvakasiyana-siyana, kusanganisira kugadzirisa mvura. Polyacrylamide inowanzoshandiswa sechinhu chinoyerera mumagadzirirwo ekurapa kwemvura kuvandudza kugadzika kwezvimedu zvakamiswa, zvichiita kuti zvive nyore kupatsanura zvimedu kubva mumvura.
Polyacrylamide (PAM) inhengo yepolymer inoshandiswa zvakanyanya mumunda wekurapa mvura. Inouya mumhando dzakawanda dzakasiyana, kusanganisira nonionic, cationic, uye anionic.

Applications
Floculant:Polyacrylamide inowanzo shandiswa se flocculant mukuchenesa mvura kubvisa yakaturikwa yakaoma, particulate nyaya uye colloids uye condense ivo muhombe flocs kufambisa kunotevera sedimentation kana kusefa. Iyi flocculation inobatsira kuvandudza kujeka kwemvura uye kujeka.
Precipitant enhancer:Polyacrylamide inogona kugadzira macomplexes ane simbi ions kuti iwedzere kuita kweiyo precipitant. Pakurapa mvura yetsvina ine simbi ions, kushandiswa kwepolyacrylamide kunogona kuvandudza mhepo yekunaya uye kuderedza zvirimo zvesimbi ions mumvura yetsvina.
Antiscaant:Mukugadzirisa kwemvura, polyacrylamide inogona zvakare kushandiswa seyero inhibitor kudzivirira kuyera pamusoro pepombi nemidziyo. Inovandudza ion balance yemvura, inodzivisa kuiswa kwezvinhu zvakanyungudutswa mumvura, uye inoderedza kuumbwa kwechiyero.
Kunatsiridza kunaka kwemvura:Polyacrylamide inogona zvakare kushandiswa kuvandudza kunaka kwemvura mune dzimwe nguva, senge kuwedzera chiyero chesedimentation yezvakarembera zvakamira mumvura, kuderedza kuumbwa kwematope, nezvimwe.
Soil solidification:Mukusimba kwevhu uye kuvandudzwa, polyacrylamide inogona kushandiswa kuvandudza kugadzikana uye kusaora kwevhu, nekudaro kuvandudza humiro hwevhu.
Zvinofanira kucherechedzwa kuti chipimo chepolyacrylamide chinofanirwa kunyatsodzorwa panguva yekushandiswa kudzivirira mhedzisiro yakaipa pane zvakatipoteredza. Mukuwedzera, iyo chaiyo yekushandisa inoenderana nezvinodiwa chaizvo zvekurapa kwemvura uye maitiro emhando yemvura.
