Umatshini wokubuyisela kunye nokunciphisa i-tin slagisebenzisa iindlela ezicacileyo zokwenyama ukunciphisa i-oxidized tin slag kwi-peak tin eziko kwi-tin egqityiweyo ngaphandle kokongeza nayiphi na i-reagents yeekhemikhali ukuqinisekisa umgangatho wemveliso kwaye inokusetyenziswa ngokuthe ngqo kwimveliso, ukonga ngaphezu kwe-50% yeendleko kunye nokuphucula ukusebenza kakuhle kwezoqoqosho;
Yonke inkampani esebenzisa i-wave/selective soldering system inayo, kodwa yintoni na kwaye ungayinciphisa njani okanye uyilahle njani?
I-Dross yi-85-90% ye-solder ngoko ibalulekile kwinkampani.Ngexesha lokuthengiswa kwamaza emoyeni, iioksidi zenza umphezulu wesolder etyhidiweyo.Ziyasuswa kumphezulu wamaza ngeebhodi ezicutshungulwayo zinyanzela i-solder kunye neeoksidi ukuba zixube kwindawo yokuhlambela kwaye ngaphantsi nje komphezulu wembiza engatshintshiyo.Umyinge wokwenziwa kwenkunkuma ixhomekeke kubushushu be-solder, ukuphazamiseka, uhlobo lwe-alloy / ubunyulu kunye nezinye izinto ezingcolisayo / izongezo.Uninzi lwento ebonakala ngathi yintlenga, eneneni, ziiglobhu ezincinci zesolder eziqulethwe yifilimu encinci yeoxide.Okukhona i-solder iguquguquka ngakumbi, kokukhona kuveliswa inkunkuma.Ngokuxhomekeke kwi-flux esetyenziswayo kwinkqubo i-dross ingaba njenge-sludge okanye ngaphezulu njengomgubo.Uhlalutyo lwenkunkuma xa yahluliwe kwi-solder ibonisa intsalela ukuba yi-oxides yenkcenkce kunye nelothe.
Njengoko indibano idlula kwi-solder, iintsimbi ezahlukeneyo ebhodini ziya kunyibilika zibe yitoti etyhidiweyo.Ixabiso langempela letsimbi elichaphazelekayo lincinci kakhulu, kodwa inani elincinci lokungcoliswa kwesinyithi linokuchaphazela isenzo sombhobho we-solder, kwaye sinokubonakala kwimbonakalo ye-solder joint.Ngokuqhelekileyo, njengoko ubhedu sesona sinyithi sixhaphakileyo sithengiswa kuya kuba sesona ntsholongwane sihlala sinamava kwi-solder.Esona solder kwinkunkuma nangona kunjalo siya kuba nomxholo we-alloy ofanayo kunye namanqanaba ongcoliseko njengakwimbiza ye-solder ngoko ke inexabiso kwaye inokuthengiswa kwakhona kumthengisi.Isixa se-solder kwintlenge siya kuchaphazela ixabiso elihlawulwe kwakhona kwi-scrap kunye nexabiso lentsimbi ngelo xesha.
Inkunkuma kumphezulu webhafu engatshintshiyo ikhusela kwi-oxidation eyongezelelweyo.Ngoko ke, akufanele isuswe rhoqo kunokuba kuyimfuneko.Kuphela ukuba iphazamisana nentshukumo yamaza, inqanda ulawulo lwenqanaba le-solder okanye inokubangela umkhukula njengoko amaza avuliwe.Kanye ngosuku ngokuqhelekileyo kuyanelisa ukuba umgangatho ochanekileyo we-solder embizeni unokujongwa kwaye awuvumelekanga ukuba uwise.Ukuba inqanaba le-solder liyehla liya kuchaphazela ukuphakama kwamaza e-solder ngokuthe ngqo.Ngexesha lokuchithwa kwe-drossing inani le-solder kwi-dross inokulawulwa ngeendlela zomqhubi zokususa.Ukunyamekela kunokunciphisa kakhulu inani le-alloy elungileyo elisuswe kwindawo yokuhlambela.Nangona kunjalo abasebenzi abasoloko benikwa ixesha lokukhupha ibhafu ngendlela yokunciphisa inkunkuma.
Khumbula ukuba imaski kufuneka isoloko isetyenziswa xa kucolwa inkunkuma kumaza, kwaye uyibeke kwisikhongozeli esivaliweyo esikhutshwa simahla kumthengisi we-solder.Oku kuthintela ukuba nokwenzeka kwamasuntswana othuli lwelothe amancinci ukuba angene emoyeni.Cinga ngokusetyenziswa kwe-surfactant ukukhupha i-solder ngaphandle kwentlenga.Inkunkuma ngokuqinisekileyo inokuthengiswa ibuyele kumthengisi we-solder ukuze ihlanjululwe kwaye isetyenziswe kwakhona kwezinye izicelo.
Nge-solder engenalo i-lead amanqanaba enkunkuma anokuba phezulu kodwa anokugcinwa kumanqanaba amkelekileyo kunye nokukhethwa okuchanekileyo kwe-alloy yokuqala.Umphezulu we-solder kunye neempawu ziya kuhluka kunye ne-lead-free solder, umzekelo omnye wale nto ubhedu.Kwibhafu engenalothe, amanqanaba obhedu anokuba phakathi kwe-0.5-0.8% ukuqala ngokunyuka ngexesha lemveliso.Kwibhafu yenkcenkce/yelothe oku kuya kuthathwa njengokungaphezulu kwamanqanaba ongcoliseko.
