Txog kev txheeb xyuas cov yeeb nkab tooj liab zoo thiab qhov hnyav thiab qhov ntev ntawm cov txheej txheem suav
Cov yeeb nkab tooj liab yog hais txog cov khoom siv tooj liab ua los ntawm nias los yog kos tooj liab. Vim nws cov khoom muaj zog thiab hnav-tiv taus, nws feem ntau siv hauv cov khoom siv hluav taws xob, kev lag luam thiab kev tsim kho. Cov kav dej tooj liab tuaj yeem tsim los ntawm extrusion, nruam casting thiab dov, thiab kev kos duab. Tube tooj liab yog ib qho tseem ceeb raw khoom rau kev ua thiab kev tsim cov khoom siv tub yees. Nws muaj ob qho kev siv tseem ceeb:
1. Ua kom muaj cua sov;
2. Ua cov kav dej txuas thiab fittings;
1. Kev faib tawm ntawm cov kav dej tooj liab
1. Cov kav dej cua txias tuaj yeem muab faib ua cov cua txias zoo li cov kav dej tooj liab thiab degreasing cua txias cov kav dej tooj liab:
Lub tshuab cua txias: Lub thickness feem ntau yog {{0}}.5mm tuab rau 2-point thiab 3-point raj, 0.6mm tuab rau 4- point tubes, thiab 0.7mm tuab rau 5-point thiab 6-point tubes. Feem ntau siv rau R22.
Degreased cua txias cov yeeb nkab tooj liab: kuj hu ua "degreased cua txias tooj liab yeeb nkab", lub 2-point thiab 3-point pipes yog 0.8mm tuab, thiab cov 4- taw tes, 5-point thiab 6- cov kav dej yog 1.0mm tuab. Feem ntau siv rau cov tub yees xws li R410.
2. Kev faib tawm tshwj xeeb ntawm cov khoom cua txias tooj liab yeeb nkab:
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), uas yog tus yam ntxwv los ntawm cov ntsiab lus oxygen tsawg heev thiab a me me ntawm deoxidizer tshuav nyob rau hauv deoxidized tooj liab;
Oxygen tooj liab: feem ntau suav nrog cov tooj liab ntshiab zoo tib yam (T1, T2, T3, thiab lwm yam) thiab tawv tooj liab, uas muaj cov ntsiab lus siab oxygen;
Cov tooj liab tshwj xeeb: Muaj arsenic tooj liab, nyiaj tooj liab, tellurium tooj liab, thiab lwm yam. Cov yam ntxwv yog tias cov kab sib txawv ntawm cov khoom sib txawv yog ntxiv kom ua tiav lub hom phiaj ntawm kev txhim kho tag nrho cov khoom siv.
Tam sim no cia peb tsom mus rau tooj liab thiab tooj dag.
Copper tube: Lub raj tooj liab siv hauv peb lub tub yees kev lag luam yog tooj liab ntshiab, nrog cov ntsiab lus tooj liab ntau dua 99.90%. Nws muaj cov khoom zoo ntawm cov tooj liab, cov hlau zoo tshaj plaws, thiab tau siv dav hauv ntau yam kev lag luam thiab pej xeem thiab ua lub luag haujlwm tseem ceeb. nyhuv. Feem ntau muaj peb pawg: TP2, T2 thiab TU1.
TP2 yog phosphorus-deoxidized tooj liab, muaj 0 015-0.04% phosphorus. Nws muaj cov khoom siv vuam zoo thiab txias txias thiab siv dav hauv kev tsim khoom ntawm cov cua txias thiab tub yees txuas cov kav dej, qhov cub hluav taws xob txuas kav, hluav taws xob cua sov kav thiab lwm yam kev lag luam.
T2 yog tooj liab ntshiab nrog cov ntsiab lus tooj liab siab dua 99.90%. Thaum cov neeg siv muaj kev xav tau kev ua tau zoo dua rau cov khoom siv, T2 tooj liab raj yuav yog thawj qhov kev xaiv.
TU1 yog tooj liab tsis muaj oxygen, nrog cov ntsiab lus tooj liab ntau dua lossis sib npaug li 99.97%, tsis tshua muaj oxygen thiab impurity cov ntsiab lus, siab purity, zoo heev hluav taws xob thiab thermal conductivity, zoo ductility, thiab kev ua tau zoo, vuam, corrosion kuj, thiab txias tsis kam. . Vim yog qhov yuav tsum tau ua ntau lawm thiab cov nqi siab, nws cov khoom lag luam tus nqi ntau dua li lwm hom tooj liab raj.
Brass tube: tooj liab-zinc alloy raj. Tus lej tom qab H tsab ntawv hauv qib feem ntau sawv cev rau tus nqi nruab nrab ntawm nws cov ntsiab lus tooj liab, thiab cov ntsiab lus zinc yog cov nyiaj seem. Cov raj tooj dag ntawm cov qib sib txawv, raws li cov ntsiab lus tooj liab ua ntau dua thiab siab dua, feem ntau qhia tau zoo dua thiab kev ua haujlwm elongation. Feem ntau yog siv los ua cov khoom sib txuas rau cov kav dej thiab dej wading.
2. Kev txiav txim siab ntawm cov raj tooj liab zoo
1. Feem ntau, thaum yuav khoom, koj yuav tsum tau soj ntsuam cov tsos ntawm cov yeeb nkab tooj liab los txiav txim. Thawj qhov yog saib cov xim ntawm cov yeeb nkab tooj liab. Ua cov xim sib txawv raws li hom tooj liab yeeb nkab yuav. Piv txwv li, liab tooj liab kav, feem ntau liab tooj liab nrog ib tug reddish xim yog zoo dua. Tooj liab, inferior tooj liab muaj impurities nyob rau hauv nws.
2. Feem ntau, cov raj zoo tooj liab yog ua los ntawm cov tooj liab ntshiab thiab muaj kev nthuav dav zoo dua, yog li cov raj zoo tooj liab yuav muaj kab sib sib zog nqus. Tom qab khawb hauv cov yeeb nkab 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 haum yog qhov siab. Tab sis yog tias xim lossis lwm yam sib txawv, nws muaj peev xwm muaj qee yam khoom zoo li hlau ntxiv rau nws. Txawm li cas los xij, cov kav dej tooj liab zoo dua feem ntau yog siv hauv kev lag luam tub rog thiab lwm yam kev lag luam tshwj xeeb.
3. Feem ntau cov txheej txheem tooj liab feem ntau muab faib ua peb hom: tawv, semi-hard thiab mos. Cov duab sib txawv muaj qhov sib txawv. Feem ntau, lawv tuaj yeem txiav txim siab los ntawm kev khoov lub raj tooj liab. High-quality tooj liab raj yog yooj yim heev rau khoov. Nws yog khoov, tab sis yog tias nws yog ib qho nyuaj rau khoov los yog kab nrib pleb tshwm sim tom qab khoov, nws qhia tau hais tias qhov zoo ntawm cov yeeb nkab tooj liab fittings tsis zoo heev.
Cov ntsiab lus: Cov kav dej tooj liab zoo muaj cov yas zoo, thaum cov kav hlau tsis zoo tsis muaj hlau nplaum rau ntawm qhov chaw thiab muaj cov kab nrib pleb thiab qhov pits, qhov, thiab lwm yam ntawm qhov chaw.
