Cov ntaub ntawv muaj txiaj ntsig 丨 Kev faib tawm thiab kev txheeb xyuas ntawm cov raj tooj liab
Vim tias tooj liab thiab nws cov khoom siv alloy muaj qhov zoo xws li kev ua zoo plasticity, conductivity thiab corrosion kuj, lawv tau maj mam dhau los ua ib qho ntawm cov khoom siv dav tshaj plaws hauv tib neeg lub neej thiab kev tsim khoom hauv kuv lub teb chaws.
Cov raj tooj liab xa mus rau cov khoom siv tooj liab ua los ntawm kev nias lossis kos tooj liab. Lawv yog cov khoom siv tseem ceeb tshaj plaws hauv kev ua thiab kev tsim cov khoom siv tub yees. Muaj ob txoj hauv kev tseem ceeb los siv lawv.
① Ua cov khoom siv hluav taws xob. Xws li feem ntau siv evaporators thiab condensers, feem ntau hu ua "ob qho khoom siv";
② Ua cov kav dej txuas thiab cov yeeb nkab fittings.
Txawm hais tias lub hom phiaj, nws yog ib qho channel rau cov tub yees, thiab nws lub luag haujlwm tseem ceeb heev, uas yuav tsum muaj cov tshuab cua txias thiab cov tub yees siv cov tub yees siv cov raj tooj liab kom zoo.
Kev faib tawm ntawm cov raj tooj liab
Lub tshuab cua txias tooj liab tuaj yeem muab faib ua cov cua txias zoo tib yam tooj liab raj thiab degreased cua txias tooj liab raj.
Cov cua txias zoo tib yam tooj liab raj: Lub thickness feem ntau yog {{{0}}.5mm rau 2-point thiab 3-point raj, 0.6mm rau 4- point tubes, thiab 0.7mm rau 5-point thiab 6-point tubes. Feem ntau siv rau R22, lub siab tswj ntawm 0.98MPa;
Degreased cua txias tube tooj liab: tseem hu ua "deoiled cua txias tube tooj liab", {{0}}point thiab 3-point tubes yog 0.8mm tuab, 4-point , 5-point thiab 6-point yog 1.0mm tuab. Feem ntau yog siv rau cov tub yees tshiab xws li R410, lub siab yog tswj ntawm 1.8MPa;
Kev faib tawm tshwj xeeb ntawm cov khoom cua txias tooj liab tube
Oxygen-dawb tooj liab: suav nrog high-purity oxygen-dawb tooj liab (TU0, TU1, TU2) thiab phosphorus deoxidized tooj liab (TUP, TP1, TP2, thiab lwm yam), muaj cov pa oxygen thiab qee qhov impurities, tab sis tag nrho cov ntsiab lus oxygen tsis ntau tshaj 0.003%, thiab purity ntawm tooj liab yog ntau dua 99.95%. Cov khoom siv tooj liab tsis muaj pa oxygen feem ntau yog siv hauv kev lag luam hluav taws xob, xws li cov khoom siv suab, lub tshuab nqus tsev hluav taws xob, cables, thiab lwm yam.
Cov tooj liab tshwj xeeb: arsenic tooj liab, nyiaj tooj liab, tellurium tooj liab, thiab lwm yam., cov yam ntxwv yog qhov sib txawv ntawm cov kab hlau sib txuas ntxiv, xws li As, Ag, Te, thiab lwm yam, kom ua tiav lub hom phiaj ntawm kev txhim kho kev ua tiav ntawm cov khoom siv.
Oxygen tooj liab: feem ntau zoo tib yam tooj liab ntshiab (T1, T2, T3, thiab lwm yam) thiab tawv tooj liab, ntshiab tooj liab uas muaj cov pa oxygen thiab deoxidizer residue, nrog cov yam ntxwv ntawm cov pa oxygen tooj liab.
Brass tube: tooj liab-zinc alloy tube, tus lej tom qab tsab ntawv H hauv hom feem ntau sawv cev rau tus nqi nruab nrab ntawm nws cov ntsiab lus tooj liab, thiab cov ntsiab lus zinc yog qhov seem. Brass tubes ntawm ntau hom, nrog ntau dua thiab ntau dua tooj liab cov ntsiab lus, feem ntau qhia tau hais tias zoo thiab elongation kev ua tau zoo, thiab feem ntau yog siv raws li cov kav dej thiab wading connectors.
Copper tube: Lub raj tooj liab siv hauv peb lub tub yees kev lag luam yog tooj liab, nrog cov ntsiab lus tooj liab ntau dua 99.90%. Nws muaj cov khoom zoo ntawm cov tooj liab hlau, cov khoom siv hlau zoo, thiab tau siv dav hauv ntau yam kev lag luam thiab kev siv pej xeem, thiab ua lub luag haujlwm tseem ceeb. Muaj peb hom: TP2, T2, thiab TU1.
Tooj tooj
Cia peb tham txog ntau yam khoom siv ntawm cov raj tooj liab.
① TP2 yog phosphorus deoxidized tooj liab, muaj 0. kev sib txuas cov kav dej, hluav taws xob cua sov kav, thiab lwm yam.
② TU1 yog tooj liab tsis muaj oxygen, nrog cov ntsiab lus tooj liab ntau dua lossis sib npaug li 99.97%, cov ntsiab lus tsis tshua muaj oxygen thiab impurity, siab purity, zoo heev hluav taws xob thiab thermal conductivity, zoo ductility, kev ua tau zoo, vuam, corrosion kuj, thiab txias. tsis kam. Vim nws cov kev xav tau ntau lawm thiab cov nqi siab, nws cov khoom lag luam tus nqi ntau dua li lwm yam ntawm cov raj tooj liab.
③ T2 yog tooj liab ntshiab, nrog cov ntsiab lus tooj liab ntau dua 99.90%. Thaum cov neeg siv muaj kev xav tau hluav taws xob ntau dua rau cov khoom siv, T2 tooj liab raj yuav yog thawj qhov kev xaiv.
TP2 tooj liab tuaj yeem siv rau cov cua txias thiab tub yees txuas cov kav dej
Copper tube zoo txiav txim txoj kev

Hauv kev yuav khoom, nws yog ib qho tsim nyog yuav tau soj ntsuam cov xim ntawm lub raj tooj liab thiab ua cov xim sib txawv raws li hom tooj liab raj yuav. Zoo li tooj liab raj, liab tooj liab nrog ib tug reddish xim yog feem ntau zoo tooj liab. Kuj tseem muaj cov raj tooj dag, uas feem ntau zoo dua nrog cov xim sib dua. Qee cov tooj liab tsis zoo tuaj yeem tawg ua ob daim los ntawm kev khoov lawv nrog koj txhais tes vim yog impurities hauv. Tsis txhob yuav lawv yog tias muaj cov impurities dub hauv.

Kov cov phab ntsa sab hauv ntawm lub raj tooj liab nrog koj txhais tes kom pom tias nws du thiab huv si, thiab saib seb puas muaj qhov tsis xws luag xws li xuab zeb qhov, oxidation, thiab tawg. Yog tias koj tsis paub meej, koj tuaj yeem khawb lub raj tooj liab nrog ib qho khoom ntse. Feem ntau, cov raj zoo tooj liab yog ua los ntawm cov tooj liab ntshiab thiab muaj cov ductility zoo dua, yog li cov raj zoo tooj liab yuav muaj kab sib sib zog nqus. Tom qab khawb qhov sab hauv ntawm lub raj tooj liab, yog tias nws zoo ib yam li cov phab ntsa sab nrauv, nws txhais tau hais tias tag nrho qhov zoo ntawm cov yeeb nkab tooj liab yog qhov siab. Txawm li cas los xij, yog tias xim lossis lwm yam sib txawv, nws muaj peev xwm muaj qee yam khoom xws li hlau tau ntxiv rau nws.

Feem ntau, cov txheej txheem tooj liab tau muab faib ua peb hom: tawv, semi-hard, thiab mos. Kev hloov pauv ntawm cov ntawv sib txawv kuj txawv. Feem ntau, nws tuaj yeem txiav txim siab los ntawm kev khoov lub raj tooj liab. High-quality tooj liab raj yog yooj yim heev rau khoov, tab sis yog hais tias nws yog ib qho nyuaj rau khoov los yog kab nrib pleb tshwm sim tom qab khoov, nws txhais tau hais tias qhov zoo ntawm cov tooj liab raj tsis zoo heev.
Yog tias koj xav txiav txim siab ntxiv qhov zoo ntawm cov raj tooj liab, koj yuav tsum tau ua qhov kev xeem zoo. Zoo li qee qhov kev sim tshuaj muaj pes tsawg leeg, cov cuab yeej tshaj lij yuav muaj qhov tseeb ntau dua hauv kev txiav txim siab.
