Iyo tin slag kudzoreredza uye kuderedza muchinainoshandisa nzira chaidzo dzemuviri kudzikisa oxidized tin slag muchoto chepamusoro muchoto chakapedzwa pasina kuwedzera chero makemikari reagents kuve nechokwadi chemhando yechigadzirwa uye inogona kushandiswa zvakananga mukugadzira, kuchengetedza inodarika 50% yemitengo uye kugadzirisa hupfumi;
Kambani yega yega iri kushandisa wave/selective soldering system inayo, asi chii uye ungaideredza sei kana kurasa?
Dross is 85-90% solder saka yakakosha kukambani.Munguva yemafungu ekutengesa mumhepo, okisidhi inoumba pamusoro peiyo solder yakanyungudutswa.Vanotamiswa pamusoro pemasaisai nemabhodhi ari kugadziriswa achimanikidza solder nemaokisi kuti asanganise panzvimbo yekugezera uye nechepazasi pepamusoro pepoto isingachinjiki.Muyero wekugadzira tsvina unoenderana nekupisa tembiricha, kubvongodza, rudzi rwechisanganiswa/kuchena uye zvimwe zvinosvibisa/zvinowedzera.Zvakawanda zvezvinoita kunge marara, kutaura zvazviri, magirobhu madiki e solder ane firimu rakatetepa reoxide.Kunyanya kubvongodza nzvimbo ye solder, marara anowedzera kugadzirwa.Zvichienderana nekuyerera kuri kushandiswa mukuita marara anogona kuita semarara kana kupfuura sehupfu.Ongororo yemarara kana yapatsanurwa kubva kune solder inoratidza yasara kuve maokisi erata nemutobvu.
Sezvo gungano richipfuura nepamusoro pe solder, simbi dzakasiyana-siyana pabhodhi dzichanyunguduka mugaba rakanyungudutswa.Iyo chaiyo chiyero chesimbi inobatwa idiki kwazvo, asi diki diki yekusvibiswa kwesimbi inogona kukanganisa kuita kweiyo solder wave, uye inogona kuratidzwa mukuonekwa kweiyo solder joint.Kazhinji kutaura, sezvo mhangura ndiyo inonyanya kutengeswa simbi inotengeswa ichava yakanyanya kusvibiswa inotapukira mune solder.Iyo chaiyo solder mumarara zvisinei ichava neyakafanana alloy content uye mazinga ekusvibiswa sezviri mupoto inotengeswa saka ine kukosha uye inogona kutengeswa kudzokera kumutengesi.Huwandu hwekutengesa mumarara huchakanganisa mutengo wakabhadharwa kusara uye kukosha kwesimbi panguva iyoyo nenguva.
Dora riri pamusoro peiyo static bath inodzivirira kubva kune imwe oxidation.Nokudaro, haifaniri kubviswa kakawanda kupfuura zvakakodzera.Chete kana ikakanganisa mafungu ekuita, inorambidza kutonga kweiyo solder level kana inogona kukonzera mafashama sezvo wave wakavhurwa.Kamwe pazuva kazhinji zvinogutsa zvakapa iyo chaiyo nhanho ye solder muhari inogona kuongororwa uye haibvumidzwe kudonha.Kana iyo solder level ikadonha inozokanganisa solder wave kureba zvakananga.Panguva yekudonhedza chiyero che solder mumarara chinogona kudzorwa neanoshanda nzira dzekubvisa.Kuchengetedza kunogona kuderedza zvakanyanya kuwanda kwealloy yakanaka yakabviswa kubva mubhati.Zvakadaro vashandi havawanzo kupihwa nguva yekubvisa tsvina yekugezesa nenzira yekudzikisa tsvina.
Rangarira mask inofanirwa kugara ichishandiswa pakubvisa tsvina kubva pasaisai, uye isa mumudziyo wakavharwa unowanzo kupihwa mahara kubva kune mutengesi.Izvi zvinodzivirira mukana wekuti guruva diki remutobvu ripinde mumhepo.Funga nezvekushandiswa kwechigadzirwa chepamusoro kuti solder ibude mumarara.Dorosi rinogona kutengeswa kudzoka kumutengesi wekutengesa kuti acheneswe uye ashandisezve mune mamwe maapplication.
Iine lead-isina solder mazinga emarara anogona kukwirisa asi anogona kuchengetedzwa pamazinga anogamuchirwa nesarudzo chaiyo yearoyi yekutanga.Nzvimbo ye solder uye maitiro achave akasiyana nemutobvu-isina solder, mumwe muenzaniso weiyi mhangura.Mumutobvu-isina kugeza mhangura mazinga angave ari pakati pe0.5-0.8% kutanga nekuwedzera panguva yekugadzirwa.Mubhavhu retin/lead izvi zvinganzi zviri pamusoro pemazinga ekusvibisa.
