Polyacrylamidehe pūmua raina wairewa-wai i hangaia mā te whakapūmua rauropi kore utu o ngā monomer acrylamide. I taua wā anō, ko te polyacrylamide hydrolyzed he flocculant maimoatanga wai pūmua, ka taea te mimiti
ngā matūriki e iri ana i roto i te wai, e whai wāhi ana ki te hono me te hono i waenga i ngā matūriki, e hanga ana i ngā putunga nui o ngā matūriki angiangi, ā, e whakateretere ana i te tere o te maturuturunga iho.
PHPA Pūmuae toru ngā momo anionic, cationic me te non-ionic i roto i tēnei rauemi, ā, i runga i tēnei kaupapa, ka wehea te polyacrylamide pam ki ngā tauira raupapa rerekē.I te aroaro o ngā momo polyacrylamide maha, ka taka pea te hunga kore-toi ki ngā hē e whai ake nei:
Te Mārama Hē 1: Ko te teitei ake o te taumaha/ionitanga ngota, ko te pai akeHe maha ngā momo tauira o te polyacrylamide anionic mai i te 3 miriona ki te 22 miriona e ai ki te taumaha ngota, i te meapolyacrylamide kationikahe maha ngā momo tauira mai i te 30% ki te 70%.
Ina hoki, he rerekētanga nui te kōwhiringa o te polyacrylamide flocculant me te taumaha ngota/ionicity rerekē i roto i te pānga maimoatanga o te kounga wai rerekē. He tino iti te awhe horopeta mō te pānga pai rawa atu, ā, ki te nui ake te pam cationic i tētahi awhe, ka puta he pānga kino. Nō reira, me whakamahi i ngā MSDS polymer cationic hei whakatau i te tauira motuhake e tika ana mō te polyacrylamide e ai ki te ahumahi tono tuturu, te kounga wai, ngā taputapu maimoatanga me ētahi atu āhuatanga.
Te Mārama Hē 2: Whakamahia te momo kotahiPAMmō te momo wai para kotahi
Hei tauira, ko te wai para hanga pepa kotahi, tera pea he rerekētanga anō hoki i roto i te pH, te matū rauropi, te matū kore rauropi, te tae, te SS, me ētahi atu. Kāore e taea e te momo polyacrylamide kotahi te whakaoti rapanga katoa, ā, ka taea e ngā momo wai para katoa te tutuki i ngā tukanga. Me tīpako te Polyacrylamide i roto i te PAURA i roto i te tauira mā te whakamātautau iti, kātahi ka whakamatautauria ki te mīhini hei whakatau i te horopeta tino pai, kia tutuki ai te hua pai o te horopeta iti me te utu iti.
Te Mārama Hē 3: Ko te nui o te horopeta, ko te pai ake
I raro i ngā āhuatanga noa, ka piki ake te pānga o te whakapūpū i te pikinga o te nui o te whakapūpū, engari ki te nui rawa te nui o te whakapūpū, ka hoki anō te whakapūpū hei kōroiti pumau, ā, ka piki ake te matotoru o te wai, kia piki ake ai te ātete o te kōroiti iri i roto i te wai. Ka whiwhihia te horopeta tino pai mā roto i ngā whakamātautau motuhake e ai ki te nui o ngā matū totoka iri.
Pūrākau 4: Ko te tere o te whakaoho, ko te roa rānei o te wā, ko te pai ake
Ki te tere rawa te whakaoho, ā, ki te roa rawa te wā, ka pakaru ngā matūriki nunui o ngā totoka.
hei matūriki iti, ā, ko ngā matūriki ka taea te whakaputa ka pakaru hei matūriki kāore e taea te whakaputa.
Te Mārama Hē 5: He puhoi rawa te tere o te whakaoho, he poto rawa rānei te wā
Mena he puhoi rawa te tere, ā, he poto rawa te wā, kāore e taea e te flocculant te tino pa atu ki ngā matūriki totoka, kāore e pai mō te flocculant ki te hopu i ngā matūriki colloidal, ā, kāore te tohatoha kukū o te flocculant i te ōrite, he mea kino ake te mahi a te flocculant.
Te Mārama Hē 6: ngā kationa,ngā anion, ā, he tino mārama kore ngā kore-ion
Kāore i te mārama te kōwhiringa o ngā kāwai taketake. He nui te rerekētanga utu i waenga i te cation, te anion me te non-ion, ā, kāore he huarahi hei tīmata mai i te huarahi whānui, hei whiriwhiri rānei i te kāwai hē. I roto i ngā tono mahi, ka taea hoki te whakarōpū whānuitia penei:
He pai te polyacrylamide cationic mō te flocculation, te sedimentation, te decolorization, te whakamārama, me ētahi atu o te kounga wai matatini, te tango wai paru tāone, te tango wai paru waro, me ētahi atu; Te Whare Maimoatanga Para o Haina
He pai ngā anion mō te whakaheke i te wai para, te whakatōtō, te tango wai, te whakamārama, me ētahi atu, ā, ka taea hoki te whakamahi mō te whakamaroke i te paru kore-ora;
Polyacrylamide kore-ioniche pai mō te pupuri wai o te oneone, te whakaheke waipara waikawa ngoikore, te whakatō, te maroke, me ētahi atu.
Kua tino tohunga a Yixing cleanwater chemicals co., ltd ki te whakapai ake i te whakahaere taonga me te pūnaha QC kia mau tonu ai te hua nui i roto i te kamupene whakataetae nui mō te Kōwhiringa Nui mō te Haina Anionic PAM/Polyacrylamide mō ngā tono maimoatanga wai, me te kaupapa "ko te kiritaki tuatahi, ko te whakapono", nau mai ki ngā kaihoko ki te waea mai, ki te īmēra mai rānei ki a mātou mō te mahi tahi.
He Kōwhiringa Nui mō ngā kaihanga wairewa o Haina.
