Qaladaadka doorashada PAM flocculant, imisa ayaad ku tallaabsatay?

Polyacrylamidewaa polymer toosan oo biyo-milmi kara oo uu sameeyay polymerization xagjirka bilaashka ah ee monomers acrylamide. Isla mar ahaantaana, polyacrylamide hydrolyzed sidoo kale waa flocculant daaweynta biyaha polymer, kaas oo nuugi kara

Qaybaha biyaha ee hakadka ku jira, waxay door ka ciyaaraan isku xirka iyo isku xidhka qaybaha, waxay sameeyaan qaybo yaryar oo samaysmaya xawli aad u weyn, waxayna kordhiyaan xawaaraha roobka.
Polymer PHPACaadi ahaan waxaa ka mid ah saddex nooc oo anionic ah, cationic iyo non-ionic, iyadoo taas ku saleysan, pam polyacrylamide waxaa loo qaybiyaa noocyo taxane ah oo kala duwan.Marka ay jiraan noocyo badan oo polyacrylamide ah, kuwa aan xirfad-yaqaannada ahayn waxay ku dhici karaan is-faham-darrada soo socota:
Faham la'aanta 1: Mar kasta oo uu sareeyo miisaanka molecular/ionity, ayaa ka sii wanaagsanAnionic polyacrylamide guud ahaan waxay leedahay noocyo kala duwan oo u dhexeeya 3 milyan ilaa 22 milyan marka loo eego miisaanka kelli, halkapolyacrylamide cationicwuxuu leeyahay noocyo kala duwan oo u dhexeeya 30% ilaa 70%.

Dhab ahaantii, xulashada polyacrylamide flocculant oo leh miisaan unugyo kala duwan / ionicity ayaa farqi weyn u leh saameynta daaweynta tayada biyaha kala duwan. Qiyaasta qiyaasta ee saameynta ugu fiican waa mid aad u yar, oo haddii pam cationic uu dhaafo xad gaar ah, waxay keeni doontaa saameyn xun. Sidaa darteed, cationic polymer msds waa lagama maarmaan si loo go'aamiyo qaabka gaarka ah ee ku habboon ee polyacrylamide iyadoo loo eegayo warshadaha codsiga dhabta ah, tayada biyaha, qalabka daaweynta iyo xaaladaha kale.

Faham la'aanta 2: Isticmaal nooc isku mid ahPAMbiyaha wasakhda ah ee la midka ah
Tusaale ahaan, isla warqad-samaynta biyaha wasakhda ah ayaa sidoo kale laga yaabaa inay ku kala duwanaadaan pH, walxaha organic, walxaha aan organic, chromaticity, SS, iwm. Ma jiro nooc ka mid ah polyacrylamide oo xallin kara dhammaan dhibaatooyinka, iyo dhammaan noocyada bulaacada waxay noqon karaan u hoggaansanaanta habka. Polyacrylamide ee budada ah ayaa lagama maarmaan u ah in lagu doorto qaabka iyada oo loo marayo tijaabo yar, ka dibna ku tijaabi mashiinka si loo go'aamiyo qiyaasta ugu fiican, si loo gaaro saameynta ugu fiican ee qiyaasta yar iyo kharash yar.

Faham la'aanta 3: Inta badan qiyaasta qiyaasta, ayaa ka sii fiican

Xaaladaha caadiga ah, saamaynta qulqulka ayaa kordhin doonta korodhka qadarka qulqulka, laakiin haddii qadarka flocculant uu ka badan yahay, flocculant wuxuu noqon doonaa kolloid xasilan mar kale, iyo viscosity ee biyaha ayaa kordhi doona, si ay u caabbinta sedimentation. kolloidka hakadka ku jira ee biyaha ayaa kordhin doona. Qiyaasta ugu fiican waxaa lagu helaa tijaabooyin gaar ah iyadoo loo eegayo waxa ku jira adkaha la hakiyey. 

Khuraafaadka 4: Sida ugu dhakhsaha badan xawaaraha wax-karinta ama wakhtiga dheer, ayaa ka sii wanaagsan

Haddii xawaaruhu aad u dheereeyo oo wakhtigu aad u dheer yahay, qaybaha waaweyn ee walxaha adag waa la jebin doonaa

qaybo yaryar oo yaryar, qaybaha soo dajin karana waxay u kala jajabaan qaybo aan la soo dajin karin.

Faham la'aan 5: Xawaaraha kicinta aad buu gaabis u yahay ama wakhtigu aad buu u gaaban yahay

Haddii xawaaruhu aad u gaabiyaan waqtiguna aad u gaaban yahay, flocculant-ku si buuxda ulama xidhiidhi karo qaybaha adag, kuwaas oo aan ku haboonayn in flocculant-ku uu qabsado qaybaha kolloidalka, iyo qaybinta fiirsashada ee flocculant ma aha mid la mid ah, taas oo xitaa ka sii badan. aan fiicnayn in la ciyaaro doorka flocculant.

Faham la'aanta 6: cations,anions, iyo non-ions waa nacasnimo cad

Doorashada qaybaha aasaasiga ah ma cadda. Farqiga qiimaha u dhexeeya cation, anion iyo non-ion waa xoogaa weyn, mana jirto si looga bilaabo jihada guud ama dooro qaybta khaldan. Codsiyada dhabta ah, waxa kale oo loo kala saari karaa qiyaas ahaan sida:

Cationic polyacrylamide waxay ku habboon tahay qulqulka, kala-saarista, midabaynta, caddaynta, iwm. tayada biyaha adag, nadiifinta dhoobada magaalada, nadiifinta dhoobada organic, iwm .; Warshad Daaweynta Bullaacadaha Shiinaha

Anions waxay ku habboon yihiin qulqulka bulaacada, wasakhaynta, nadiifinta, caddaynta, iwm, waxaana sidoo kale loo isticmaali karaa fuuq-baxa dhoobada aan organic;

Nonionic polyacrylamidewaxay ku habboon tahay ceshanka biyaha ciidda, qulqulka wasakhda aashitada oo daciif ah, qallafsanaanta, fuuqbaxa, iwm.

Hal qayb oo ka mid ah Yixing Cleanwater Chemicals Co., Ltd. ltd waxay sidoo kale ku takhasustay hagaajinta maamulka walxaha iyo nidaamka QC si loo hubiyo inaan ilaalin karno faa'iido weyn oo ka dhex jirta shirkadda aadka u tartanta ee Xulashada Weyn ee Shiinaha Anionic PAM / Polyacrylamide ee Codsiyada Daaweynta Biyaha, Iyadoo mabda'a ah "rumayn ku salaysan, macmiilka marka hore", Yixing Cleanwater Chemicals Co., Ltd. ku soo dhawoow dukaameeystayaasha inay si fudud noogu soo wacaan ama iimayl noogu soo diraan iskaashi.

Xulasho weyn oo loogu talagalay soosaarayaasha Shiinaha ee milmaya.

laga soo xigtay baydu.
