Tsis sib xws Sediment Deposition Defect ntawm Plate Surfaces
Cov phaj cua sov npog nrog PTFE txheej yog dav siv rau hauv cov kua qaub sib xyaw-alkali sib xyaw da dej siv rau PCB desmear, multi-theem electroplating pretreatment thiab hydrometallurgy fractional extraction. Tom qab ob peb lub lis piam ntawm kev ua haujlwm tas mus li, pom tseeb tsis sib xws fouling tshwm rau ntawm qhov chaw tiaj tus: tuab cov pob zeb siv lead ua pob zeb ua ke rau ntawm ib feem ntawm cov cheeb tsam thaum lwm qhov chaw nyob huv. Qhov kev pab cuam asymmetric no tsim cov thermal tsis sib xws thoob plaws lub phaj, ua rau muaj cua sov hauv zos, tsis ruaj khov da dej kub thiab ua haujlwm luv luv. Cov neeg ua haujlwm saib xyuas feem ntau tsuas yog ua tiav tag nrho - phaj tu tsis tu ncua yam tsis tau tshawb nrhiav cov hauv paus ntawm kev sib sau tsis sib xws. Ntev- lub sij hawm ntawm - cov ntaub ntawv saib xyuas qhov chaw ua pov thawj cov kua dej tsis sib haum thiab qhov sib txawv ntawm lub cheeb tsam kub yog qhov tseem ceeb ua rau cov av tsis sib xws.
Tsim Mechanism ntawm Asymmetric Surface Fouling
Cov chav da dej sib xyaw muaj ntau cov hlau hydroxide, sulfate thiab chloride ions. Sediment nag lossis daus tus nqi yog zoo correlated nrog lub zos kub thiab kua ntws tshaj tawm. Slow- ntws stagnant zones nyob ib ncig ntawm cov cua kub daim hlau khaws cov khoom ncua sij hawm ntev. Nyob rau hauv cov cua kub, yaj ions crystallize thiab nruj nreem rau PTFE nto. Cov cheeb tsam uas muaj cov kua convection sai sai tshem tawm cov khoom me me tsis tu ncua thiab NW nyuam qhuav tsim cov deposits. Lub caij no, lub kaum sab xis ntawm kev teeb tsa tsis sib xws, thaiv cov kab sib txuas thiab ntug qhov chaw txias ua rau cov chaw tuag tas mus li, qhov twg cov txheej tuab fouling sib sau sai heev. Lub thicker sediment ntxiv nce hauv zos thermal kuj, elevates lub regional deg kub thiab accelerates siv lead ua nag lossis daus, ua rau tus kheej - amplifying vicious voj voog.
Peb Lub Cev Tsis Muaj Kev Tswj Xyuas Fouling Distribution Uniformity
Qhov sib txawv ntawm qhov hnyav -fouling thiab huv cheeb tsam yog txiav txim los ntawm cov kua ncig ceev, phaj kab rov tav flatness thiab nruab nrab ion saturation degree. Deviations los ntawm tus qauv txuam cov xwm txheej aggravate asymmetric sediment accumulation obviously.
| Ua haujlwm Parameter | Uniform Fouling Safe Range | Uneven Deposition Risk Range | Hauv zos Sediment Thickness Gap |
|---|---|---|---|
| Circulation Flow Velocity | 6-10 L / min txawm ntws faib | Ib nrab ntws hauv qab 2 L / min tuag cheeb tsam | 0.04-0.09 hli thickness txawv |
| Phaj Kab rov tav Mounting Level | Lub kaum sab xis Tsawg dua lossis sib npaug li 1 degree | Lub kaum sab xis Loj dua lossis sib npaug li 3 degree | 0.03-0.07 hli thickness txawv |
| Mixed Ion Saturation Level | Unsaturated dilute daws | Ze ntawm -saturation siab- nruab nrab concentration | 0.05-0.10 hli thickness txawv |
Kev lag luam-Tshwj xeeb Balanced Circulation Optimization Plans
PCB Alternate Acid-Base Treatment Tanks
PCB sib xyaw da dej hloov cov qauv tshuaj nquag thiab nqa cov ntsev ions saturated. Multi-point symmetrical circulating nozzles tau teeb tsa nyob ib puag ncig cov phiaj xwm cua sov kom tshem tawm cov chaw tuag. Lub hli kab rov tav calibration ntawm phaj mounting brackets tiv thaiv ib tug -sab sediment buildup tshwm sim los ntawm qaij.
Multi-Stage Hardware Electroplating Pre-Tshuaj Kab
Electroplating degreasing thiab ua kom cov tso tsheb hlau luam ua ke tsim hydroxide precipitates. Tsawg- nrawm nrawm nrawm nrawm khiav tsis yog- nres thaum lub sijhawm ua haujlwm hloov pauv kom tsis txhob muaj qhov sib haum xeeb ntawm cov phaj phaj.
Hydrometallurgy Fractional Extraction Vessels
Metallurgical mix leaching kua tuav cov hlau hnyav ion ntsiab lus. Dav - cheeb tsam sib npaug faib cov cua sov phaj ua ke nrog cov agitators hauv qab tshem tawm cov txheej txheem ua kua tsis tu ncua, ntsuas cov av xaum nrawm thoob plaws txhua qhov chaw phaj.
Universal Operation & Installation Guidelines
Cov fouling tsis sib xws ntawm cov phaj cua sov tsis tuaj yeem daws tau yooj yim los ntawm kev ua kom huv si ntau zaus. Cov kev daws teeb meem tseem ceeb nyob rau hauv kev ntsuas cov kua dej thiab tswj cov kab rov tav tiaj tus installation kom tshem tawm qhov chaw tuag nyob qhov twg cov muaju sib sau ua ke. Tsim nyog cov qauv tsim thiab kev soj ntsuam qib tsis tu ncua ua kom cov pob zeb tuab zoo ib yam, tsis txhob muaj cua sov ib nrab thiab thermal efficiency attenuation. Factories nrog kev sib xyaw ua ke siab - ion tshuaj da dej thiab qhov hnyav asymmetric fouling tuaj yeem tau txais kev hloov pauv cov raj xa dej thiab cov kab rov tav txoj kev hloov kho rau cov phiaj xwm cua sov, ua kom cov av tsis sib xws thiab ncua sij hawm ntawm kev tu offline.
