PCB bolodi kukonzekera kumabweretsa mavuto amachitidwe

1. Pali mavuto ambiri achilendo mu njira ya PCB, ndipo wopanga makinawo nthawi zambiri amatenga udindo wofufuza zamtsogolo (kusanthula zifukwa zoyipa ndi mayankho ake). Chifukwa chake, cholinga chachikulu choyambitsa zokambiranazi ndi kukambirana m’modzi m’modzi pazida za zida, kuphatikiza zovuta zomwe zingayambitsidwe ndi anthu, makina, zida ndi momwe zinthu ziliri. Ndikukhulupirira mutha kutenga nawo mbali ndikukhazikitsa malingaliro anu ndi malingaliro anu

2. Khalani okhoza kugwiritsa ntchito zida za prereatment, monga mzere wamkati wosanjikiza,

3. Tengani chithandizo chisanachitike cha anti-welding (kukana kutsekemera) kwa PCB dera bolodi monga chitsanzo (opanga osiyanasiyana): kutsuka ndikupera * magulu awiri -> kutsuka madzi -> pickling asidi -> kutsuka madzi -> mpeni wa mpweya wozizira -> kuyanika gawo -> kulandira ma disc a dzuwa -> kutulutsa ndikulandila

4. Kawirikawiri, maburashi achitsulo okhala ndi matayala a burashi a # 600 ndi # 800 amagwiritsidwa ntchito, omwe angakhudze kukhathamira kwa bolodi, kenako ndikukhudza kulumikizana pakati pa inki ndi mkuwa. Pogwiritsidwa ntchito kwakanthawi, ngati zinthuzo sizikuyikidwa molingana kumanzere ndi kumanja, ndikosavuta kutulutsa mafupa agalu, omwe angapangitse kuzungunuka kosafanana kwa bolodi, ngakhale kusintha kwa mzere ndi kusiyanasiyana kwamitundu pakati pamkuwa ndi inki mutatha kusindikiza, Chifukwa chake, ntchito yonse ya burashi imafunika. Pamaso pa ntchito yopera burashi, kuyesa kwa burashi kuyenera kuchitika (kuyesa kuswa madzi kudzawonjezeredwa ngati D / F). Mlingo wa burashi womwe umayesedwa ndi pafupifupi 0.8 ~ 1.2mm, yomwe imasiyanasiyana malinga ndi zinthu zosiyanasiyana. Burashi itasinthidwa, mulingo wa gudumu la burashi udzakonzedwa, ndipo mafuta opaka mafuta adzawonjezeredwa pafupipafupi. Ngati madzi saphika pakamagaya burashi, kapena kuthamanga kwa utsi kumakhala kocheperako kuti kukhale ngodya yooneka ngati fan, ufa wamkuwa ndiosavuta kuchitika, Phulusa la mkuwa pang’ono limayambitsa dera lalifupi (waya wandiweyani) kapena mayeso osakwanira okwanira pakanthawi kumaliza mankhwala mayeso

Vuto lina losavuta pakudyetsa mankhwalawa ndi makutidwe ndi okosijeni am’mapepala, omwe amatsogolera ku zotumphukira pamtunda kapena patadutsa H / A

1. Malo olumikizirana ndi madzi olimba a prereatment ndi olakwika, kotero kuti acid imabweretsedwa mgawo lotsuka madzi mopitilira muyeso. Ngati kuchuluka kwa akasinja am’madzi kumbuyo sikukwanira kapena madzi obayidwa sakukwanira, zotsalira za asidi pamtunda zidzayambitsidwa

2. Kutsika kwamadzi kapena zonyansa m’gawo lotsuka madzi zimapangitsanso kulumikizana kwa zinthu zakunja pamkuwa

3. Ngati cholandirira madzi chouma kapena chodzaza ndi madzi, sichingathe kuchotsa bwino madzi pazogulitsidwazo kuti zikonzeke, zomwe zingapangitse madzi otsalira kwambiri pamtunda ndi mdzenje, ndi mpeni wotsatira wa mphepo sungathe kugwira bwino ntchito yake. Pakadali pano, ambiri mwa ma cavitation omwe amakhala kumapeto kwa dzenje ali misozi

4. Pakadali kutentha kotsalira panthawi yotulutsa, mbaleyo imapindidwa, yomwe imadzaza mkuwa pamwamba pake

Nthawi zambiri, pH chowunikira chingagwiritsidwe ntchito kuwunika pH yamadzi, ndipo infrared ray itha kugwiritsidwa ntchito kuyeza kutulutsa kotsalira kotsalira pambale. A retractor mbale mbale waikidwa pakati pa kumaliseche ndi okwana mbale retractor kuziziritsa mbale. Konyowetsa koyendetsa madzi kuyenera kufotokozedwa. Ndibwino kukhala ndi magulu awiri amateyala oyamwa madzi kuti azitsuka mosiyanasiyana. Mbali yomwe mpeni wa mpweya ukuyenera kutsimikiziridwa isanachitike tsiku ndi tsiku, ndipo samalani ngati ngalande ya mpweya mu gawo loyanika imagwa kapena yawonongeka
