Muaj tseeb cov neeg uas tau kho tsheb, cov kav dej hauv nruab nrab, cov kav dej, thiab lwm yam, tau dhau los ntawm lub tswv yim xws li kev vuam txias rau cov hlau, thiab yuav muaj tseeb hais tias qhov no yog ob lub ntsiab lus nplaum nrog qhov sib ntxiv. ntawm cov hmoov hlau. Ntawm ib sab, qhov no muaj tseeb, tab sis ntawm qhov tod tes, cov lus teb zoo li no yuav tsis tiav, vim tias lub tswv yim no kuj muaj lwm lub ntsiab lus.
1. Txias yas vuam
Raws li GOST 2601-84 uas twb muaj lawm, kev vuam txias ntawm cov hlau yog vuam ua haujlwm yam tsis muaj kev siv cov cua sov, kev sib txuas ntawm cov hlau uas tshwm sim vim qhov tseem ceeb ntawm cov yas deformation uas tshwm sim los ntawm kev ua haujlwm ntawm cov khoom. tuaj koom.
hom vuam no yog siv los koom nrog cov khoom ua los ntawm tooj liab, npib tsib xee, txhuas, nyiaj, cadmium, hlau. Txoj kev no yog tshwj xeeb tshaj yog zoo rau fastening qhov chaw ua los ntawm dissimilar hlau los yog thaum siv hlau uas rhiab heev rau tshav kub. Cov yas txias deformation vuam tuaj yeem yog qhov chaw, seam lossis pob tw.
Soldering cov ntsiab lus siv txoj kev no yog cov txheej txheem nyuaj heev thiab yuav tsum tau siv cov cuab yeej tshwj xeeb, thiab yog li lwm txoj kev tau txais kev faib tawm ntau tshaj plaws (tshwj xeeb hauv lub neej txhua hnub).
2. Txias vuam rau epoxy raws hlau
Txoj kev no yog qhov tshwj xeeb uas nws tso cai rau koj txuas cov khoom los ntawm ntau yam khoom: hlau, ceramics, yas, iav, ntoo, thiab lwm yam.
Cold welding rau hlau muaj nyob rau hauv kev ua lag luam niaj hnub no, tus nqi uas feem ntau tsis tshaj ib puas rubles, muaj nyob rau hauv ntau yam kev xaiv ntim: sticks, hub, raj. Tab sis, tsis hais lub version, nws yuav tsum tau raws li epoxy kua nplaum nrog ntxiv ntawm cov hmoov hlau kom nws muaj zog tshwj xeeb. Tsis tas li ntawd, txhua yam ntawm cov fillers, modifiers, plasticizers, thiab lwm yam yog ntxiv nyob rau hauv txhua rooj plaub, txias vuam rau hlau muaj ob yam nyob rau hauv nws muaj pes tsawg leeg - resin thiab hardener, tom qab sib tov uas cov txheej txheem hardening pib.
Vim tias hom vuam no zoo heev, nws feem ntau siv los kho cov kav dej, lub tank roj, lub tshuab hluav taws xob (suav nrog cov cua kub hauv nruab nrab).
Cold welding rau hlau: cov lus qhia rau kev siv
Nyob ntawm hom thiab cov chaw tsim khoom, nws tuaj yeem tsim tau hauv ob lub raj lossis lub thawv, uas yuav tsum yogsib tov sib xyaw. Qhov kev xaiv zoo tshaj plaws yog vuam txias rau bar hlau.
Nws yooj yim siv. Ua ntej ntawm tag nrho cov, koj yuav tsum tau npaj qhov chaw kom fastened, uas yuav tsum tau ntxuav ntawm av, yog hais tias ua tau ntxuav thiab degreased. Rau qhov no, roj av los yog cov kuab tshuaj yog tsim nyog. Tom qab ntawd, nrog ob txhais tes ntub dej, siv qhov xav tau ntawm vuam thiab knead nws hauv koj txhais tes li 3-5 feeb, kom txog thaum nws zoo li plasticine hauv nws qhov sib xws. Tom qab ntawd, siv nws mus rau qhov chaw yuav tsum tau koom nrog thiab nias. Yog tias tsim nyog, tshem tawm cov vuam ntau dhau nrog spatula. Ua kom tiav ziab ntawm cov vuam txias tshwm sim hauv ib hnub, tom qab ntawd cov khoom tuaj yeem siv tau zoo.
