Demin Dej System rau Circuit Boards

Lub tshuab dej demin rau lub rooj tsav xwm hauv Circuit Court yog ib qho dej huv uas tshem tawm cov dej ntxhia thiab cov kab mob ionic los ntawm cov dej kom tsim tau siab - cov dej huv huv siv hauv cov ntawv luam tawm Circuit Board (PCB) tsim thiab tu.
Yooj yim txhais
Lub tshuab dej demin tshem tawm cov zaub mov xws li calcium, magnesium, sodium, chloride, thiab sulfate siv rov qab osmosis (RO) thiab deionization (DI) los yog ion- pauv resins, ua cov dej qis -conductivity dej uas tsis tso cov khoom seem ntawm cov khoom siv hluav taws xob.

Circuit boards yog heev rhiab heev rau cov kab mob. Yog tias siv cov kais dej tsis tu ncua thaum ntxuav lossis yaug, nws tuaj yeem tso cov khoom siv hluav taws xob los yog cov pob zeb hauv av, uas tuaj yeem ua rau muaj teeb meem loj.

Kev siv dej DM pab rau:

• Tiv thaiv luv luv Circuit Court tshwm sim los ntawm ionic paug
• Tsis txhob xeb ntawm cov kab tooj liab thiab cov khoom siv hluav taws xob
• Xyuas kom cov residue - ntxuav dawb ntawm PCBs
• Txhim kho cov khoom ntseeg tau thiab kev ua haujlwm ntawm hluav taws xob
• Khaws qhov chaw huv si thaum tsim khoom

Txawm tias cov ntxhia me me tuaj yeem cuam tshuam kev ua haujlwm hauv Circuit Court, tshwj xeeb tshaj yog nyob rau hauv siab -cov khoom siv hluav taws xob.

Txhawm rau tsim lub PCB deionized dej system, pib los ntawm qhov yuav tsum tau muaj dej zoo, cov khoom ntws, thiab daim ntawv thov taw tes hauv cov txheej txheem PCB. PCB ntxuav dej feem ntau yuav tsum muaj tsawg hauv ions, tsis tshua muaj cov khoom, thiab ruaj khov nyob rau hauv conductivity / resistivity yog li nws tsis tawm cov khoom seem ntawm cov laug cam.
1. Txhais daim ntawv thov ua ntej
Cov txheej txheem PCB sib txawv xav tau cov dej sib txawv.
Kev siv:

• Ua ntej- ntxuav / ntxuav
• Thaum kawg yaug tom qab tshuaj ntxuav
• Ultrasonic tu
• Kev kho deg / txheej kab yaug
• Siab -kev ntseeg tau ntawm kev ntxuav hluav taws xob

Rau qhov kawg PCB rinsing, dej spec feem ntau nruj dua li kev ntxhua khaub ncaws.

2. Paub meej tias lub hom phiaj dej zoo
Teem lub hom phiaj tsim ua ntej xaiv cov khoom siv.
Yam khoom tsim:

• Conductivity los yog resistivity
• TDS
• Silica
• Hardness
• Chloride / sulfate
• Particle theem
• TOC yog cov txheej txheem rhiab heev
• Cov kab mob / microbial tswj yog khaws cia rau hauv lub tank rau lub sijhawm ntev

Lub hom phiaj siv tau zoo rau PCB DI dej yog:

• Conductivity: qis dua 1-5 µS / cm
• Lossis Resistivity: nyob ib ncig ntawm 0.2–1.0 MΩ·cm lossis siab dua, nyob ntawm tus txheej txheem

Rau siab dua - kawg kev ntxuav hluav taws xob, qhov kawg yaug yuav xav tau kev tiv thaiv ntau dua.

3. Txheeb xyuas cov dej nyoos
Koj xav tau daim ntawv qhia txog dej nyoos ua ntej qhov ntsuas qhov system.
Qhov tseem ceeb parameter:

• Pub dej qhov chaw: municipal, zoo, dej saum npoo
• TDS
• Hardness
• Silica
• Chlorine / chloramine
• Hlau / manganese
• pH
• SDI / turbidity
• Organic load

Qhov no txiav txim siab pretreatment thiab kev khiav hauj lwm nqi.

4. Xam lub peev xwm xav tau
Loj qhov system los ntawm qhov xav tau tiag tiag, tsis yog qhov loj ntawm lub tank.
Txiav txim siab:

• Ib teev ntws xav tau rau cov kab yaug
• Kev xav tau dej txhua hnub
• Peak xav tau thaum lub sij hawm ib txhij yaug
• Rov qab hom phiaj
• Tank cia ntim

Ib txoj hauv kev siv:

• Nruam txheej txheem thov
• Ntxiv rau 10-20% tus qauv tsim
• Ntxiv rau qhov chaw cia khoom rau kev siv siab tshaj

5. Xaiv cov txheej txheem teeb tsa
Rau PCB tu, feem ntau tsim yog:
Pretreatment → RO → DI los yog EDI → Polishing lim → Cia tank → Recirculation voj
Tej theem
A. Kev kho mob
Tiv thaiv RO daim nyias nyias thiab stabilizes pub dej.
Feem ntau suav nrog:

• Raw dej tank yog xav tau
• Booster twj
• Multimedia / xuab zeb lim
• Activated carbon lim rau chlorine tshem tawm
• Dej softener lossis antiscalant dosing yog tias hardness siab
• 5 µm cartridge lim

B. Rov qab Osmosis (RO)
RO tshem tawm feem ntau cov ntsev thiab cov organic.
Cov txiaj ntsig:

• Tshem tawm 95-99% ntawm cov ions yaj
• Zoo heev txo DI resin noj
• Txo tus nqi khiav haujlwm

Rau kev lag luam PCB systems, RO feem ntau yog qhov tseem ceeb.
C. DI lossis EDI polishing
Tom qab RO, siv ib qho ntawm cov no:

• Mixed - txaj DI
• Tus nqi pib qis dua
• Siab kawg purity
• Zoo rau cov tshuab me me thiab nruab nrab
• Yuav tsum tau resin hloov/regeneration

EDI

• Kev ua haujlwm tsis tu ncua
• Tsis muaj tshuaj regeneration ntawm resin txaj
• Zoo dua rau qhov loj dua, ruaj khov -flow systems
• Tus nqi pib siab dua

Rau ntau lub chaw tsim khoom PCB:

• RO + sib xyaw txaj DI yog ntau
• RO + EDI + lub txaj sib xyaw yog siv thaum xav tau ntau dua purity thiab automation

D. Thaum kawg polishing
Txhawm rau tiv thaiv cov txheej txheem yaug:

• 0.2-1 µm kawg lim
• Optional UV
• Kev xaiv zaum kawg sib xyaw- txaj polisher rau purity siab heev

6. Piv txwv ntawm tus qauv Demin Dej System Rau Circuit Boards
Ib tug qauv tsim tej zaum yuav yog:
Raw tank → Booster twj tso kua mis → multimedia lim → activated carbon lim → softener → 5 µm lim → RO unit → RO permeate tank → mix - txaj DI → 0.2 µm zaum kawg lim → DI dej tank → recirculation twj tso kua mis → PCB yaug cov ntsiab lus
Rau siab dua - kawg ntau lawm:
Pretreatment → ob - dhau RO → EDI → sib xyaw - txaj polishing → UV → 0.2 µm lim → voj tis

Yog tias koj xav tsim ib qho kom raug, sau 6 yam khoom no:
1.Yuav tsum tau khiav hauv m³/hr lossis m³/hnub
2.Raw dej tsom xam: TDS, hardness, silica, chlorine, hlau
3.Application: dav dav, yaug zaum kawg, ultrasonic, siab -kev ntseeg siab PCB
4.Tim qhov hluav taws xob zoo: conductivity lossis resistivity
5.Xav tau kev khaws cia / faib lub voj lossis tsuas yog siv hauv zos xwb
6.Operation hom: nruam los yog batch
