Umshini wokubuyisela nokunciphisa i-tin slagisebenzisa izindlela ezingokoqobo ukuze inciphise i-oxidized tin slag esithandweni sethayela eliphakeme ibe yithini eliqediwe ngaphandle kokwengeza noma yimaphi ama-reagents amakhemikhali ukuze kuqinisekiswe ikhwalithi yomkhiqizo futhi ingasetshenziswa ngokuqondile ekukhiqizeni, konga ngaphezu kuka-50% wezindleko kanye nokwenza ngcono ukusebenza kahle komnotho;
Yonke inkampani esebenzisa i-wave/selective soldering system inayo, kodwa iyini futhi ungayinciphisa kanjani noma uyilahle kanjani?
I-Dross i-solder engu-85-90% ngakho ibalulekile enkampanini.Phakathi ne-wave soldering emoyeni, ama-oxide akheka ebusweni be-solder encibilikisiwe.Asuswa endaweni yawo phezu kwegagasi ngamabhodi acutshungulwayo aphoqa i-solder nama-oxides ukuthi axubane endaweni yokugeza nangaphansi nje kobuso bebhodwe elingashintshi.Izinga lokukhiqizwa kukadosi lincike ekushiseni kwe-solder, ukuyaluza, uhlobo lwengxubevange/ubumsulwa nokunye ukungcola/izithasiselo.Okuningi kwalokho okubonakala kuyimfucumfucu, eqinisweni, kungama-globule amancane e-solder aqukethwe ifilimu elincanyana le-oxide.Lapho i-solder inyakaza kakhulu, kukhiqizwa amanyela.Kuye ngokuthi i-flux isetshenziswa kanjani kule nqubo, amanyela angaba njengodaka noma ngaphezulu njengempushana.Ukuhlaziywa kwenzila lapho kuhlukaniswa nesoda kubonisa okusele njengama-oxide ethini nomthofu.
Njengoba umhlangano udlula phezu kwe-solder, izinsimbi ezihlukahlukene ebhodini zizoncibilika ethini elincibilikisiwe.Inani langempela lensimbi ethintekayo lincane kakhulu, kodwa inani elincane lokungcoliswa kwensimbi lingathinta isenzo se-solder wave, futhi lingabonakala ekubukeni kwe-solder joint.Ngokuvamile, njengoba ithusi iyinsimbi evamile edayisiwe kuyoba ukungcoliswa okuvame ukutholakala ku-solder.I-solder yangempela emanyeleni izoba nokuqukethwe kwe-alloy efanayo namazinga okungcoliswa njengasebhodweni elithengiswayo ukuze ibe nenani futhi ingathengiswa ibuyiselwe kumphakeli.Inani le-solder emanyeleni lizothinta inani elikhokhelwe emuva kokulahlwa kanye nenani lensimbi ngaleso sikhathi.
Imfucumfucu engaphezulu kwendawo yokugeza emile ivikela ekuqhumeni kwe-oxidation.Ngakho-ke, akufanele isuswe kaningi kunalokho okudingekayo.Kuphela uma iphazamisa isenzo samagagasi, ikhawulela ukulawulwa kwezinga le-solder noma ingase ibangele isikhukhula njengoba igagasi livuliwe.Kanye ngosuku ngokuvamile kuyanelisa inqobo nje uma izinga elilungile le-solder ebhodweni lingase liqashwe futhi alivunyelwe ukwehla.Uma izinga le-solder lehla lizothinta ukuphakama kwegagasi le-solder ngokuqondile.Ngesikhathi sokukhipha inani le-solder emanzini lingalawulwa izindlela zomqhubi zokususa.Ukunakekelwa kunganciphisa kakhulu inani le-alloy enhle ekhishwe ekugezeni.Kodwa-ke abasebenzi abavamisile ukunikwa isikhathi sokususa udoti okugeza ngendlela yokunciphisa imfucuza.
Khumbula ukuthi imaski kufanele isetshenziswe njalo lapho ukhipha amanyela kumagagasi, futhi ubeke esitsheni esivaliwe esinikezwa mahhala kumthengisi.Lokhu kugwema ukuthi kungenzeka izinhlayiya zothuli lomthofu ezincane zingene emoyeni.Cabangela ukusetshenziswa kwe-surfactant ukukhipha i-solder eweni.Amalahle angathengiswa abuyiselwe kumthengisi we-solder ukuze ahlanzwe futhi asetshenziswe kabusha kwezinye izinhlelo zokusebenza.
Nge-solder engenamthofu amazinga emfucumfucu angaba phezulu kodwa angagcinwa emazingeni amukelekayo ngokukhethwa okulungile kwengxubevange yokuqala.Ubuso be-solder nezici zizohluka nge-solder-free-solder, isibonelo esisodwa salokhu siyithusi.Ebhavini elingenamthofu amazinga ethusi angase abe phakathi kuka-0.5-0.8% ukuqala ngokwanda ngesikhathi sokukhiqiza.Kubhavu kathayela/umthofu lokhu kuzobhekwa ngaphezu kwamazinga okungcola aphezulu.
