Ho hlahloba PolyDADMAC

Ho Lekola Kamano lipakeng tsa Boima ba Molek'hule, Viscosity, Litaba tse Tiileng, le Boleng ba PolyDADMAC

PolyDADMAC (eo hape e tsejoang e le "polydiallyl dimethyl ammonium chloride") ke polima ea cationic e sebelisoang lits'ebetsong tsa kalafo ea metsi. E bohlokoa bakeng sa flocculation ea eona e ntle le litlamorao tsa coagulant. Joaloka morekisi le morekisi oa lik'hemik'hale tse hloekisang metsi, ho bohlokoa ho utloisisa kamano lipakeng tsa boima ba limolek'hule, viscosity le litaba tse tiileng tsa PolyDADMAC le boleng ba sehlahisoa. Sehloohong sena, re tla hlahloba kamano pakeng tsa matšoao ana le mokhoa oa ho khetha lihlahisoa tsa boleng bo phahameng tse u loketseng.

Boima ba limolek'hule, viscosity le litaba tse tiileng tsa PolyDADMAC ke likarolo tsa bohlokoa tse amang phello ea eona. Li amana. E latelang ke tlhaloso e qaqileng ea bona le tlhaloso e qaqileng ea kamano ea bona:

1. Kamano

Boima ba limolek'hule bo bolela bolelele bo tloaelehileng ba ketane ea polyDADMAC ea polymer.

Boima ba limolek'hule bo phahameng ka kakaretso bo bolela liketane tse telele tsa polymer, tse ka ntlafatsang bokhoni ba ho phalla ha PolyDADMAC. 'Me boima bo phahameng ba limolek'hule ka kakaretso bo fana ka liphello tse ling, tse lumellang likaroloana tse nyenyane tse metsing hore li hokahane hammoho. E ka ntlafatsa liphello tsa phekolo ea metsi.

Leha ho le joalo, boima bo bongata ba limolek'hule bo ka boela ba lebisa ho viscosity e feteletseng, e amang ts'ebetso.

Boima ba limolek'hule ke pontšo ea bohlokoa ea boleng ba PDDMAC hobane e ama ka ho toba phello ea eona ea kopo.

Boima ba limolek'hule tsa PDADMAC hangata bo tloha ho 50,000 ho isa ho 700,000Da, mme lihlahisoa tse nang le boima bo phahameng ba limolek'hule li lokela ho feta ho 3,000,000Da.

2. Viscosity

Viscosity e bolela ho hanyetsa ha tharollo ea PolyDADMAC ho phalla.

Hangata viscosity ke 80-12,000mPa.s, hape ho na le polyDADMAC e nang le viscosity e phahameng e nang le viscosity e fetang 100,000. Viscosity e amana haufi-ufi le boima ba limolek'hule, 'me boima bo phahameng ba limolek'hule bo baka viscosity e phahameng. 'Me viscosity e ama ho solubility le dispersibility ea PDADMAC, hammoho le ts'ebetso ea eona ea ts'ebetso lits'ebetsong. Haeba viscosity e phahame haholo, ponahalo e phahameng e ka baka mathata a mang a ts'ebetso (ho fetisetsa le ho hlapolla, joalo-joalo) Viscosity ke parameter ea bohlokoa bakeng sa ho lekanya boleng ba PDADMAC hobane e bonahatsa boima ba eona ba molek'hule le ts'ebetso ea kopo.

3. Litaba tse tiileng

Litaba tse tiileng li bolela peresente ea boima ba polymer ka tharollo ea PolyDADMAC.

Lintho tse phahameng tse tiileng li bolela ho fokotsa litšenyehelo tsa polokelo le thepa. Leha ho le joalo, haeba sehlahisoa se nang le boima bo phahameng ba molek'hule se lokisitsoe e le tharollo ea 40%, se ke ke sa tšolloa le ho tsoa ka moqomong.

Likahare tse tiileng tsa PolyDADMAC ke 10% kapa 50%, ke hore, karolo ea lintho tse sebetsang hantle tharollong.

Hangata, litaba tse tiileng tsa PolyDADMAC tseo re li rekisang li ka ba 40%. Hape re na le litlhaloso tse ling tse tiileng tsa litaba.

O ka hlahlobaTlhaloso e qaqileng ea sehlahisoa sa PolyDADMACbakeng sa lintlha tse tobileng le matšoao a qaqileng a PolyDADMAC.

Likamano pakeng tsa bona:

Boima ba molek'hule le viscosity:

Bakeng sa litaba tse tiileng tse tšoanang, boima ba molek'hule bo phahame, ho ba le viscosity e kholoanyane.

Ha boima ba limolek'hule bo le boholo, ho na le viscosity e phahameng.

Litaba tse tiileng le viscosity:

Bakeng sa boima bo tšoanang ba molek'hule, ha lintho tse tiileng li phahame, li na le viscosity e kholoanyane.

Boima ba molek'hule, litaba tse tiileng, le ts'ebetso:

Boemong bo itseng bo tiileng, boima ba limolek'hule bo phahame, phello e ntle, empa viscosity e tla eketseha.

Mokhoa oa ho khetha PolyDADMAC e u tšoanelang

Viscosity e utloahalang: etsa bonnete ba hore ho na le metsi, ho qhibiliha habonolo, le ts'ebetso e ntle ea flocculation.

Haeba o hloka ho fumana mofani oa thepa e ncha ho reka PolyDADMAC, joale pele u tlameha ho fumana hore na boleng ba metsi a hau bo entsoe joang e le hore mofani oa hau a ka u thusa ho khetha mohlala o motle. Kapa u ka bolella morekisi mofuta le mohlala oa PolyDADMAC oo u o sebelisitseng pele. Kapa u ka romella PolyDADMAC ea hau e teng ho morekisi oa hau e mocha 'me u ba lumelle ho u thusa ho sekaseka le ho khetha. Tlhahlobo ea mohlala ea PolyDADMAC e ncha ke ea bohlokoa haholo, 'me u tlameha ho etsa tlhahlobo ka hloko ho fumana hore na mohlala ona o loketse haholoanyane ho uena.

E le setsebiPolyDADMAC mofani oa thepa, re ka u fa litšebeletso tsa khetho le ho u romella mehlala ea mahala. Haeba u na le litlhoko, ka kopo ikopanye le rona. Re tla u bapisa le mookameli oa papatso ea hloahloa ho u sebeletsa.
