Waa maxay daaweynta biyaha polymer?

Waa maxay polymer?
Polymerswaa unugyo ka samaysan unugyo isku xidhan oo silsilado ah.Silsiladani inta badan waa dheer yihiin waana lagu soo celin karaa si loo kordhiyo cabbirka qaabdhismeedka molecular.Unugyada gaarka ah ee silsiladda waxaa loo yaqaan monomers, iyo qaabka silsiladda waxaa lagu maamuli karaa gacanta ama wax laga beddelo si loo gaaro hanti iyo hanti gaar ah.
Abuuritaanka dhoobo qaabaynta ujeedooyin badan ayaa ah codsi ah qaabdhismeedka molecular polymer ee la beddelay.Maqaalkan, si kastaba ha ahaatee, waxaan diiradda saari doonaa polymers ee warshadaha.gaar ahaan daaweynta biyaha polymer.

Sidee polymers loogu isticmaali karaa daaweynta biyaha?
Polymers aad bay faa'iido ugu leeyihiin daaweynta biyaha wasakhda ah.Macnaha aasaasiga ah, doorka silsiladahan molecular waa in la kala saaro qaybta adag ee biyaha wasakhda ah iyo qaybteeda dareeraha ah.Marka la kala saaro labada qaybood ee biyaha wasakhda ah, way fududahay in la dhammeeyo habka iyada oo la kala saarayo adkaha iyo daweynta dareeraha, ka tagista biyo nadiif ah si ammaan ah ama qalabyada kale ee warshadaha.
Dareenkan, polymer-ku waa flocculant - walax ka falcesha adkaha adag ee biyaha ku dhex jira si ay u sameeyaan clumps loo yaqaan floc.Tani aad bay faa'iido ugu leedahay hababka daaweynta biyaha wasakhda ah, sidaas darteed polymers-yada waxaa badanaa loo isticmaalaa kaligood si ay awood ugu yeeshaan qulqulka, taas oo si fudud u saari karta adkaha.Si kastaba ha noqotee, si loo helo natiijada ugu fiican ee habkan, flocculant polymer ayaa inta badan loo isticmaalaa xinjirowga.
Xididaduhu waxay u qaadaan habka qulqulka ilaa heerka ku xiga, iyagoo ururinaya xadhkaha goos gooska si ay u sameeyaan lakab qaro weyn oo dhoobo ah ka dibna laga saari karo ama la daweyn karo.Daboolida polymer-ka waxay dhici kartaa ka hor intaan lagu darin xinjirowga dhiigga ama waxaa loo isticmaali karaa in lagu dardargeliyo habka korantada.Sababtoo ah korantada korantada ayaa leh faa'iidooyin iyo faa'iido darro labadaba, isticmaalka flocculants polymer si kor loogu qaado habka waa soo jeedin soo jiidasho leh maamulayaasha xarunta.

Noocyada kala duwan ee polymers-ka daaweynta biyaha
Daaweynta biyaha polymer-ka waxay u shaqeyn kartaa siyaabo kala duwan iyadoo ku xiran nooca monomer ee loo isticmaalo sameynta silsiladda polymer.Polymers guud ahaan waxay u kala baxaan laba qaybood oo ballaadhan.Waxay yihiin cationic iyo anionic, iyaga oo tixraacaya khidmadaha qaraabada ee silsiladaha molecular.

polymers Anionic ee daaweynta biyaha
polymers-ka Anionic si xun ayaa loo dallacay.Tani waxay ka dhigaysaa inay si gaar ah ugu habboon yihiin inay u rogaan adkaha aan organic ahayn, sida dhoobada, dhoobada ama noocyada kale ee ciidda, xalalka qashinka.Biyaha wasakhda ah ee ka yimaada mashaariicda macdanta ama warshadaha culus ayaa laga yaabaa inay qani ku yihiin nuxurkan adag, sidaas darteed polymers anionic ayaa si gaar ah waxtar ugu yeelan kara codsiyadaas.

polymers cationic ee daaweynta biyaha
Marka la eego kharashka qaraabada ah, polymer cationic asal ahaan waa ka soo horjeeda polymer-ka anionic sababtoo ah waxa uu leeyahay kharash togan.Kharashka togan ee polymers-ka cationic wuxuu ka dhigayaa mid ku habboon in laga saaro adkaha organic ee xalalka biyaha wasakhda ah ama isku dhafka ah.Sababtoo ah tuubooyinka bulaacada madaniga ah waxay u muuqdaan inay ka kooban yihiin xaddi badan oo walxo organic ah, polymers cationic ayaa inta badan loo adeegsadaa dhirta lagu daweeyo bulaacada ee dawlada hoose, in kasta oo tas-hiilaadka beeraha iyo cuntada ay sidoo kale isticmaalaan polymers-kan.

Polymers-ka caadiga ah waxaa ka mid ah:
Polydimethyl diallyl ammonium chloride, polyamine, polyacrylic acid/sodium polyacrylate, cationic polyacrylamide, iwm.
