Libaka tsa kopo ea polyaluminium chloride e tšoeu

Polyaluminium chloride e tšoeu(hape e tsejoa e le spray drying Polyaluminium Chloride) e sebelisoa haholo mafapheng a mangata ka lebaka la bohloeki bo phahameng le litšobotsi tse tlaase tsa litšila. Tse latelang ke maemo a eona a mantlha a ts'ebeliso le melemo ea tekheniki:

Ho noa metsi le Metsi a Liindasteri phekolo
1. tlhoekiso e phahameng ea polokeho
2. polyaluminium chloride e tšoeu ha e na litšila tse boima ba tšepe, 'me karolo ea tšepe e ka tlase ho 100ppm, e ka finyellang maemo a metsi a nooang (gb15892-2009). Boleng ba metsi a hloekisitsoeng bo pepenene ntle le masalla.
3. mocheso o tlase le ho qhibiliha ka katleho
4. e ntse e ka qhibiliha ka potlako 'me ea etsa li-flocs sebakeng se tlaase sa mocheso, se loketseng ho hloekisa metsi libakeng tse ka leboea kapa mariha.
5. ho ikamahanya le maemo ho pharaletseng
6. e sebetsa ho metsi a ka tlas'a lefatše, metsi a letamo, metsi a linōka le mehloli e meng ea metsi, e nang le mefuta e mengata ea pH (5.0-9.0), ntle le phetoho e eketsehileng ea pH.

Metsi a litšila a indasteri le kalafo e khethehileng ea metsi a litšila
1. phekolo e rarahaneng ea metsi a litšila
● ho hatisa le ho daea metsi a litšila: phello e kholo ea decolorization, e ka tlosang ho feta 90% ea chromaticity.
● metsi a litšila a mafura: karohano e sebetsang hantle ea oli-metsi ka ho se nke lehlakore ka tefiso.
● Metsi a litšila a tšepe e boima: adsorb lintho tse kotsi tse kang cadmium, chromium le fluorine ho fokotsa kotsi ea tšilafalo.
2. ho tsosolosa lisebelisoa
3. e sebelisoa bakeng sa ho hlatsoa mashala metsi a litšila pulverized mashala sedimentation le ho hlaphoheloa ha starch indastering ea starch ho ntlafatsa tšebeliso ea lisebelisoa.

Bathusi ba mantlha indastering ea pampiri
1. ho se nke lehlakore ho e-na le aluminium sulfate
2. ha e bapisoa le aluminium sulfate, polyaluminium chloride e tšoeu e ka sebelisoa tikolohong e sa nke lehlakore ho fokotsa ho bola ha lisebelisoa le bothata ba ho hloekisa metsi a masoeu.
3. ntlafatsa tshebetso ya pampiri
Eketsa calcium carbonate filler ho fokotsa litšenyehelo le ho ntlafatsa bosoeu le ho mena ha pampiri.
ho boloka le ho phalla hantle, ho fokotsa tahlehelo ea fiber le ho ntlafatsa katleho ea tlhahiso.

Lik'hemik'hale tse ntle le liindasteri tse khethehileng
1. litlolo le meriana
2. e le stabilizer kapa thepa e tala, e sebelisoa ho hloekisa meriana le mokhoa oa litlolo ho finyella tlhokahalo ea bohloeki bo phahameng.
3. ho lahla ho nepahetseng
4. joalo ka hardener, ntlafatsa ho lahla ho nepahala le ho fokotsa masala a litšila.
5. indasteri ea tsoekere
6. ts'ebetso ea decolorization le ho hlakisa e phahame, 'me chelete ea tlatsetso e hloka feela 5-10ppm ho fihlela phello ea tharollo ea tsoekere e pepeneneng.

Lisebelisoa tse ncha libakeng tse ling
1. phekolo ea tšilafalo ea mahlaseli a kotsi
2. adsorb lintho tse nang le mahlaseli a kotsi metsing bakeng sa ho hloekisa metsi a pholileng setsing sa matla a nyutlelie.
3. accelerator samente
4. potlakisa ts'ebetso ea ho beha samente le ho ntlafatsa katleho ea kaho
5. tlhoekiso ea liphoofolo tsa metsing
6. tšoara boleng ba metsi a letamo la litlhapi, fokotsa moferefere 'me u se ke ua ama ponahalo ea' mele oa metsi.

Kakaretso ea melemo ea tekheniki
● litšobotsi tsa bohloeki: Al ɑ o ₃ dikahare ≥ 29.5%, motheo 50% -70%, metsi a sa tsitsang ≤ 0.3%.
● ho lumellana ha tikoloho: ho qhibiliha hantle ha mocheso o tlaase, ho senyeha ho tlaase le ts'ireletso e phahameng ea ts'ebetso.
● katleho ea litšenyehelo: tekanyo ke 1 / 3-1 / 2 feela ea reagent ea setso, 'me litšenyehelo tse ngata tsa phekolo li fokotsehile ka 15% -30%.
