Polyacrylamide, inonzi PAM, ndeyepamusoro molecular-weight polymer. Nekuda kwechimiro chayo chakasiyana chemakemikari, PAM inoshandiswa zvakanyanya mumaindasitiri mazhinji. Muminda yakadai sekurapa kwemvura, petroleum, migodhi uye kugadzira mapepa, PAM inoshandiswa sechinhu chinoshanda che flocculant kuvandudza kunaka kwemvura, kuwedzera kushanda kwemigodhi, nekuvandudza kunaka kwepepa. Kunyange zvazvo PAM ine yakaderera solubility mumvura, kuburikidza dzakananga dissolution nzira, tinogona zvinobudirira kuinyungudutsa mumvura kuti tishandise kushanda kwayo mune zvakasiyana-siyana maindasitiri ekushandisa. Vashandi vanofanirwa kutarisisa kune yayo chaiyo mirairo yekushandisa vasati vashandisa. uye matanho ekuona kuti chigadzirwa chinoshanda uye kuchengetedzwa kwemunhu.
Kuonekwa uye makemikari zvimiro zvePolyacrylamide
PAM inowanzotengeswa nenzira yehupfu kana emulsion. Pure PAM poda ichena kusvika kuchiedza yero yakatsetseka poda ine hygroscopic zvishoma. Nekuda kwehuremu hwayo hwemamorekuru uye viscosity, PAM inonyungudika zvishoma nezvishoma mumvura. Nzira dzakananga dzekunyungudika dzinoda kushandiswa pakunyungudusa PAM kuve nechokwadi chekuti yanyungudika zvizere mumvura.
Maitiro ekushandisa PAM
Paunenge uchishandisa PAM, unofanira kutanga wasarudzazvakakodzeraFlocculantpamwezvakatemwa zvinoenderana neakananga application mamiriro uye zvinodiwa. Chechipiri, zvinonyanya kukosha kuita bvunzo dzejagi nemasampuli emvura uye flocculant. Munguva ye flocculation process, iyo inomhanyisa kumhanya uye nguva inofanirwa kudzorwa kuti iwane yakanakisa flocculation maitiro. Panguva imwecheteyo, iyo dosage ye flocculant inofanirwa kugara ichiongororwa uye kugadziridzwa kuti ive nechokwadi chekuti mhando yemvura uye migodhi uye mamwe maitiro ekugadzirisa zvinosangana nezvinodiwa. Mukuwedzera, nyatsoteerera kune maitiro ekuita kwe flocculant panguva yekushandiswa, uye tora matanho akakodzera nguva yekugadzirisa kana mamiriro asina kunaka akaitika.
Zvinotora nguva yakareba sei kupera mushure mekunyungudika?
Kamwe PAM yakanyungudika zvachose, nguva yayo inoshanda inonyanya kukanganiswa nekushisa uye chiedza. Pakupisa kwekamuri, nguva yechokwadi yePAM mhinduro inowanzova mazuva 3-7 zvichienderana nerudzi rwePAM uye kusungirirwa kwemhinduro. Uye inoshandiswa zvakanyanya mukati memaawa 24-48. PAM solution inogona kurasikirwa nekushanda mukati memazuva mashoma kana yakavhenekwa nechiedza chezuva kwenguva yakareba. Izvi zvinodaro nekuti, pasi pekuita kwechiedza chezuva, iyo PAM molecular cheni inogona kutyora, zvichikonzera kuderera kweiyo flocculation maitiro. Naizvozvo, iyo yakanyungudika PAM mhinduro inofanirwa kuchengetwa munzvimbo inotonhorera uye inoshandiswa nekukurumidza sezvinobvira.
Zvekungwaririra
Iwe unofanirwa kuterera kune zvinotevera zvinhu kana uchishandisa PAM:
Nyaya Dzekuchengetedza: Paunenge uchibata PAM, zvinhu zvinodzivirira zvakakodzera zvinofanira kupfekwa, zvakadai semagirazi ekudzivirira makemikari, majasi erabhoritari, uye magirovhosi ekudzivirira makemikari. Panguva imwecheteyo, dzivisa ganda rakananga kusangana nePAM powder kana mhinduro.
Kudururwa uye Kupfapfaidza: PAM inotsvedza zvakanyanya kana yasanganiswa nemvura, saka shandisa kungwarira kudzivirira PAM poda kuti isadhure kana kumwayiwa pasi. Kana ikadirwa netsaona kana kupfapfaidzwa, inogona kuita kuti pasi patsvedze uye kukonzeresa njodzi yakavanzika kukuchengetedzwa kwevashandi.
Kucheneswa uye kubata: Kana zvipfeko zvako kana ganda zvikaita netsaona PAM poda kana mhinduro, usageza zvakananga nemvura. Kupukuta zvinyoro-nyoro PAM poda netauro rakaoma ndiyo nzira yakachengeteka.
Kuchengetedza uye Kupera Kwenguva: Granular PAM inofanira kuchengetwa mumudziyo wechiedza-uchapupu kure nechiedza chezuva nemhepo kuchengetedza kushanda kwayo. Kugara kwenguva refu kuchiedza chezuva nemhepo kunogona kuita kuti chigadzirwa chikundikane kana kutoipa. Naizvozvo, nzira dzakakodzera dzekurongedza uye kuchengetedza dzinofanirwa kusarudzwa kuti ive nechokwadi chemhando yechigadzirwa uye kugadzikana. Kana chigadzirwa chacho chikaonekwa kuti hachina basa kana kupera nguva, chinofanira kugadziriswa nenguva uye chichitsiviwa nechigadzirwa chitsva kuti chirege kukanganisa kushandiswa kwakajairika uye kuchengeteka. Panguva imwecheteyo, kutarisisa kunofanirwa kubhadharwa pakutarisa sherufu yehupenyu hwechigadzirwa uye kusimbisa kushanda kwayo kusati kwashandiswa kuburikidza neakakodzera bvunzo kana ongororo kuona kuti inosangana nezvinodiwa zvakajairwa.
