Zvikonzero zvekushata kwepolyacrylamide uye mhinduro:
Chikonzero chekutanga: polyacrylamide se organic polymer uye polymer, ine yakanaka gene boka, nekuda kweiyo yakasimba flocculation adsorption, kana iyo Yin inonyorova nzvimbo, zviri nyore kutora unyoro uye kugadzira chivharo, kunyanya kumwe kunaya kwakakura, kwakanyorova nzvimbo dzemamiriro ekunze. , kunyanya nyore kukonzera metamorphism.
Solution: polyacrylamide chengetedzo munzvimbo inotonhorera pane nyoro, panguva imwe chete mumba inofanira kuchengetedza imwe huwandu hwemhepo, kana mvura ichinaya inofanira kunyatsovharwa, muchidimbu, usasangana nemvura ine chekuita nemvura.
Chikonzero chechipiri: Mushure mekushandiswa kwepolyacrylamide, nekuda kwebasa rakabatikana, nguva yekukanganwa kuvhura bhegi repolyacrylamide kuti usimuke zvakare, zvichikonzera kutorwa kwemvura mumhepo uye kuparara kwepolyacrylamide.
Solution: pasinei nguva uye kupi, chero bedzi kuvhura polyacrylamide kurongedza bhegi, pakarepo kuputira, regai kupa mhepo mukana muduku, zvakanaka airtight.
Chikonzero chechitatu: pasherufu upenyu polyacrylamide yapera, kunyange zvazvo kushandiswa polyacrylamide pasherefu upenyu haina kufanana, asi kupera pasherufu upenyu, zvose hazvina maturo.
Kugadzirisa: Chero chinhu chine humwe hupenyu hwesherufu, kuwedzera kuhupenyu hwesherufu, saka kunyangwe matanho ekudzivirira ekuita zvakare akasimba, hazvibatsire, nekuti mukuwedzera kune yakakosha yedambudziko, kunze kunoteverwa neakakanganisika. inokurudzirwa kuti usatenga yakawandisa polyacrylamide, inokurumidza kupera kutenga, usaise iyo polyacrylamide kwenguva refu mune izvozvo.
Chikonzero chechina: polyacrylamide haana matambudziko, asi pashure vakabudirira configuration pamusoro polyacrylamide mhinduro, maawa anopfuura 24, kureva mumaawa 24 haana kushandisa mhinduro polyacrylamide.
Solution: Kunyatsotaura, chero vakabudirira configuration pamusoro polyacrylamide mhinduro, inofanira kushandiswa pakarepo mukati maawa mashoma, nokuti okuchengetera nguva pashure configuration mhinduro iri shoma, zvikasadaro hydrolysis pamusoro polyacrylamide mhinduro ruoko kuti zvinokanganisa, izvozvo. inokurudzirwa kushandisa mukati maawa makumi maviri nemana.
Maererano nenyanzvi tsvakurudzo kuti inobudirira nguva polyacrylamide iri 1 gore nguva, kana kupfuura nguva iyi, ndiani ndapota uyai pamusoro hazvina maturo, kwete chete kurasikirwa mari uye zvinhu pfuma, uye kunyange anganonoka kuvaka nguva.
Kuchengetedza kwakaringana kwepolyacrylamide
Zuva rekupera ndiyo mamiriro ezvinyorwa zvese, uye zvakafanana kune vamiririri vekuchenesa mvura. Hazvina mhosva kuti yakasimba kana mvura, zuva rekupera rakapfuura, uye njodzi yekukundikana yakanyanya. Saka unoziva sei kana polyacrylamide iri kutadza?
Nezve polyacrylamide, marudzi akasiyana epolyacrylamide, sherufu yehupenyu nguva yakasiyana. Izvi zvine zvakawanda zvekuita nechimiro chayo, nguva yekushanda kweanionic polyacrylamide ingangoita makore maviri, sherufu yehupenyu hwe cationic polyacrylamide igore rimwe. Kana zuva rekupera rakapfuura, zuva rekupera rinogona kupera.
Nzvimbo yekuchengetera yepolyacrylamide ine simba guru pahupenyu hwayo hwesherufu. Hupenyu hwesherufu hwepolyacrylamide hunogona kuwedzerwa munzvimbo ine mhepo, yakaoma uye inotonhorera. Mumamiriro ekunze ekupisa uye munyoro, hupenyu hwepasherufu hwepolyacrylamide hupfupi.
Mune dzimwe nzvimbo, nekuda kwekunyorova kwemamiriro ekunze, mamwe etsvina zvirimwa zvepolyacrylamide kuunganidza kwenguva yakareba, kurongedza muromo hakuna kusimba, hygrophilic caking, nekuti caking ye polyacrylamide flocculant, vanhu vazhinji vane mibvunzo pamusoro pekuti haina kusimba. Naizvozvo, kutadza kwepolyacrylamide kunogona kutongwa kubva pamativi maviri. Kutanga, iyo viscosity yakaderedzwa, uye iyo flocculation effect haina kunaka kana ichishandiswa.
Iyo chaiyo yekuchengetedza nzira ye polyacrylamide:
1, polyacrylamide chengetedzo, inofanirwa kuchengetedza nharaunda yakavharwa, yakaoma, kudzivirira chiedza, kudzivirira kupisa kwakanyanya, kudzivirira kunyura, kuora uye kuparara.
2, iyo nguva yekuchengetedza yepolyacrylamide haifanirwe kunge yakareba. Zvikasadaro, zvinozotungamira mukuora kwekuchembera, kazhinji iyo kutetepa iyo yekuisa pfungwa, iyo ipfupi nguva yechokwadi.
3, polyacrylamide flocculant uye yakakwira simbi ions zviri nyore kugadzira isinganyungudika gel, saka haifanirwe kuchengetwa yakanangana nemidziyo yesimbi kwenguva yakareba.
Naizvozvo, tiri kushandura nzvimbo yekuchengetedza yepolyacrylamide. Tembiricha chinhu chakakosha. Iyo tembiricha yekuchengetedza inofanira kunyatsodzorwa pasi pe50 madhigirii kudzivirira kuratidzwa kwakananga. Chechipiri, shoma shoma ye stabilizer inogona kuwedzerwa kune polyacrylamide mhinduro, yakadai sesodium thiocyanate, thiurea, sodium nitrite uye isiri-solvent methanol, kuita kuti mushonga wepolyacrylamide ugadzikane.
