1. Cov khoom siv sib txhuam
(1) Lub zog sib txuas ntawm ntau cov khoom siv solders rau tooj liab thiab tooj dag brazing tau qhia nyob rau hauv lub rooj 10.
Rooj 10 lub zog ntawm cov pob qij txha tooj liab thiab tooj dag
Thaum brazing tooj liab nrog tin lead solder, cov brazing flux uas tsis corrosive xws li rosin cawv kua lossis rosin nquag thiab zncl2 + nh4cl aqueous kua tuaj yeem xaiv tau. Qhov kawg kuj tseem siv tau rau brazing tooj dag, tooj dag thiab beryllium bronze. Thaum brazing txhuas tooj dag, txhuas tooj dag thiab silicon tooj dag, lub brazing flux tuaj yeem yog zinc chloride hydrochloric acid kua. Thaum brazing manganese dawb tooj liab, tus neeg sawv cev txhaj tshuaj tuaj yeem yog phosphoric acid kua. Zinc chloride aqueous kua tuaj yeem siv ua flux thaum brazing nrog cov hlau ua los ntawm ...
(2) Thaum siv cov hlau filler thiab flux los brazing tooj liab, cov hlau filler uas muaj nyiaj thiab cov hlau filler tooj liab phosphorus tuaj yeem siv tau. Cov hlau solder uas muaj nyiaj yog cov hlau solder nyuaj uas siv ntau tshaj plaws vim nws qhov melting point nruab nrab, processability zoo, cov khoom siv kho tshuab zoo, hluav taws xob thiab thermal conductivity. Rau cov khoom siv uas xav tau conductivity siab, yuav tsum xaiv cov hlau solder b-ag70cuzn uas muaj cov nyiaj ntau. Rau kev brazing hauv lub tshuab nqus tsev lossis brazing hauv lub cub tawg tiv thaiv huab cua, yuav tsum xaiv cov hlau b-ag50cu, b-ag60cusn thiab lwm yam khoom siv brazing uas tsis muaj cov khoom volatile. Cov hlau filler uas muaj cov nyiaj tsawg yog pheej yig, muaj qhov kub siab brazing thiab tsis muaj zog ntawm cov pob qij txha brazed. Lawv feem ntau yog siv rau kev brazing tooj liab thiab tooj liab alloys nrog qhov yuav tsum tau tsawg. Tooj phosphorus thiab tooj liab phosphorus nyiaj brazing filler hlau tsuas yog siv rau kev brazing tooj liab thiab nws cov hlau tooj liab alloys. Ntawm lawv, b-cu93p muaj cov kua dej zoo thiab siv rau kev brazing qhov chaw uas tsis raug kev cuam tshuam hauv Electromechanical, twj paj nruag thiab kev tsim khoom. Qhov sib txawv tsim nyog tshaj plaws yog 0.003 ~ 0.005mm. Cov hlau tooj liab phosphorus uas siv rau kev sib txuas ua ke (xws li b-cu70pag) muaj zog thiab conductivity zoo dua li cov hlau tooj liab phosphorus uas siv rau kev sib txuas ua ke. Lawv feem ntau yog siv rau cov pob qij hluav taws xob uas xav tau kev conductivity siab. Rooj 11 qhia txog cov khoom sib txuas ntawm ntau cov khoom siv sib txuas uas siv rau kev sib txuas tooj liab thiab tooj dag.
