Polyaluminum chloride waa sifeeyaha waxtarka sare leh ee biyaha, kaas oo nadiifin kara, qurxin kara, midabayn kara, iwm. Sababo la xiriira sifooyinka iyo faa'iidooyinka iyo baaxadda codsiga ballaaran, qiyaasta waxaa la dhimi karaa in ka badan 30% marka la barbardhigo nadiifiyeyaasha biyaha dhaqameed, iyo kharashka waxaa lagu badbaadin karaa in ka badan 40%.Waxay noqotay biyo-sifeeye heersare ah oo laga aqoonsan yahay gudaha iyo dibaddaba.Intaa waxaa dheer, polyaluminum chloride sidoo kale waxaa loo isticmaali karaa in lagu nadiifiyo tayada biyaha gaarka ah sida biyaha la cabbo iyo biyaha qasabada, sida saarista birta, saarista cadmium, saarista fluorine, ka saarida wasakhowga shucaaca, iyo saarista qulqulka saliidda.
PAC (Poly Aluminum Chloride) sifooyinka:
Polyaluminium chloride waxay u dhaxaysaa ALCL3 iyo ALNCL6-NLm] halkaas oo m ka dhigan tahay heerka polymerization iyo n waxay u taagan tahay heerka dhexdhexaadnimada alaabta PAC.Polyaluminum chloride oo loo soo gaabiyo PAC waxaa badanaa sidoo kale loo yaqaannaa chloride polyaluminium ama xinjirowga, iwm. Midabku waa jaale ama iftiin jaale ah, madow madow, madow cawlan oo adag.Alaabtu waxay leedahay sifooyin isku xidhid xoog leh, iyo inta lagu jiro habka hydrolysis, hababka jireed iyo kiimikaad sida xinjirowga, adsorption iyo roobab ayaa dhaca.
Codsiga PAC (Poly Aluminum Chloride)
Polyaluminum chloride waxaa inta badan loo isticmaalaa sahayda biyaha magaalada iyo nadiifinta qulqulka: biyaha webiga, biyaha kaydka, biyaha dhulka hoostiisa;Nadiifinta sahayda biyaha warshadaha, daaweynta bulaacadaha magaalada, soo kabashada walxaha waxtarka leh ee biyaha wasakhda warshadaha iyo hadhaaga qashinka, kor u qaadista sdimentation of dhuxusha wasakhda ah ee dhuxusha lagu dhaqo, wax soo saarka istaarijka Dib-u-warshadaynta istaarijka;chloride polyaluminum waxay nadiifin kartaa biyaha wasakhda ah ee warshadaha kala duwan, sida: daabacaadda iyo dheehidda biyaha wasakhda ah, biyaha haragga ah, biyaha wasakhda ah ee fluorine ku jira, biyaha wasakhda ah ee birta culus, biyaha wasakhda ah ee saliidda leh, biyaha wasakhda ah ee waraaqaha lagu sameeyo, biyaha wasakhda ah ee dhuxusha lagu dhaqo, biyaha wasakhda macdanta, samaynta biyaha wasakhda ah, biyaha wasakhda ah ee macdanta, hilibka hilibka Ka-hortagga biyaha wasakhda ah, iwm;Polyaluminum chloride ee loogu talagalay daawaynta bullaacadaha: cabbirka waraaqaha samaynta, sifaynta sonkorta, shubista samaynta, ka hortagga laalaabka marada, qaadaha kicinta, sibidhka dawooyinka sifaynta degdega ah, alaabta ceeriin ee la isku qurxiyo.
Tusmada tayada ee PAC (polyaluminum chloride)
Waa maxay saddexda tilmaame ee tayada ugu muhiimsan ee PAC (polyaluminum chloride)?Saliidda, qiimaha PH, iyo aluminiumka ka kooban ee go'aamiya tayada chloride polyaluminum waa saddexda tilmaame ee tayada ugu muhiimsan ee chloride polyaluminum.
1. Saliidnimada.
Heerka hydroxylation ama alkalization ee nooc gaar ah oo ku jira PAC (polyaluminum chloride) waxaa loo yaqaan heerka aasaasiga ah ama alkalinity.Waxaa guud ahaan lagu muujiyey saamiga molar ee aluminium hydroxide B=[OH]/[Al] boqolkiiba.Saliiddu waa mid ka mid ah tilmaamayaasha ugu muhiimsan ee chloride polyaluminum, kaas oo si dhow ula xiriira saameynta qulqulka.Markasta oo ay sare u kacdo fiirsashada biyaha ceyriinka ah iyo korodhka cusbada, ayaa ka sii fiicnaan doonta saamaynta qulqulka.Si loo soo koobo, marka loo eego kala duwanaanta qulqulka biyaha ceeriin ee 86 ~ 10000mg / L, salinity-ka ugu fiican ee chloride polyaluminum waa 409 ~ 853, iyo sifooyin kale oo badan oo chloride polyaluminum ah ayaa la xiriira salinity.
2. qiimaha pH
pH ee xalka PAC (polyaluminum chloride) sidoo kale waa tilmaame muhiim ah.Waxay ka dhigan tahay qaddarka OH- ee gobolka xorta ah ee xalka.Qiimaha pH ee chloride polyaluminum guud ahaan wuxuu kordhiyaa kororka aasaasiga ah, laakiin cabitaannada leh noocyo kala duwan, ma jiro xiriir u dhigma oo u dhexeeya qiimaha pH iyo aasaaska.Dareeraha leh fiirsashada salinity isku mid ah waxay leeyihiin qiyamka pH kala duwan marka fiirsashada ay ka duwan tahay.
3. Waxyaabaha aluminiumka ah.
Maaddada aluminium ee ku jirta PAC (polyaluminum chloride) waa cabbirka qaybaha waxtarka leh ee alaabta, kaas oo xiriir gaar ah la leh cufnaanta qaraabada ee xalka.Guud ahaan marka loo hadlo, marka ay sii weynaato cufnaanta qaraabada, ayaa sare u kaca maadada aluminiumka.Viscosity of polyaluminum chloride waxay la xiriirtaa maaddooyinka aluminiumka, iyo mawgu wuxuu kordhiyaa kororka maadada aluminiumka.Marka la eego xaaladaha isku midka ah iyo isku-dhafka aluminiumka, viscosity of polyaluminum chloride wuxuu ka hooseeyaa kan aluminium sulfate, kaas oo aad ugu habboon gaadiidka iyo isticmaalka.
