Cellulose coated electrodes tiv thaiv lub molten hlau nrog ib tug gaseous cheeb tsam nyob ib ncig ntawm lub arc thiab cov vuam cheeb tsam. Cov ntxhia coated electrode tsim ib tug slag deposit. Lub shielded arc los yog hnyav coated electrodes yog siv rau vuam steels, cam khwb cia hlau, thiab hard surfacing.
Ntawm no, dab tsi yog txheej txheej ntawm vuam pas nrig?
Cov electrode yog coated nyob rau hauv ib tug hlau sib tov hu ua flux, uas muab tawm gases raws li nws decomposes los tiv thaiv vuam Kev sib kis, qhia txog deoxidizers kom huv si vuam , ua vuam -tiv thaiv slag rau daim ntawv, txhim kho lub arc stability, thiab muab alloying ntsiab los txhim kho lub vuam zoo.
Tom qab, lo lus nug yog, cov khoom siv twg yog siv rau txheej electrode? Qhov yooj yim electrode txheej yog tsim los ntawm calcium carbonates thiab fluorite. Qhov no coated electrodes yuav tsum ua kom tiav cov khoom siv kho tshuab uas xav tau ntawm cov hlau uas nws tau npaj rau vuam (tensile, cuam tshuam lub zog, CTOD, creep, thiab lwm yam).
Qhov thib ob, welding rods yog dab tsi?
A vuam electrode yog ua nce ntawm ob ntu: cov hlau tiag tiag, thiab cov txheej txheem flux. Cov hlau tuaj yeem sib txawv ntawm cov hlau me me, cam khwb cia hlau, stainless hlau, high-tensile steel, tooj liab, bronze, tooj dag, lossis txhuas.
Dab tsi yog 7018 vuam pas nrig ua los ntawm?
Cov 7018 qws welds carbon hlau mus txog 225 amps. Cov 7018 arc welding pas nrig feem ntau yog siv rau lub hom phiaj dav dav vuam ntawm carbon steel. Nws yog ib qho hlau me me rod uas yog coated nrog ib tug tsawg-hydrogen, hlau-raws li flux compound uas vaporizes los tiv thaiv lub molten vuam hlaws los ntawm kev sib kis los ntawm huab cua thiab noo noo.

Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog txheej txheej sab nraud ntawm lub hnub hu ua?
Cov txheej sab hauv yog Core, Radiative Zone thiab Convection Zone. Cov txheej txheej sab nrauv yog Photosphere, Chromosphere, Thaj Chaw Hloov Pauv thiab Corona
Puas yog rods Gram tsis zoo los yog zoo?
Gram positive rods tsawg dua li Gram negative rods. Tag nrho cov seem yog Gram negative rods. Gram zoo rods; Actinomyces, Atopobium, Bacillus, Bifidobacterium, Clostridium, Corynebacterium, Erysipelothrix, Gardnerella, Listeria, Lactobacillus, Mycobacterium sp
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
