Tooj dag raj yog lub raj ua los ntawm cov hlau tsis muaj ntsej muag hlau. Tooj dag yeeb nkab - Cov hlau dag raws li Tuam Tshoj "tsis muaj cov hlau ntawm Suav", alloys Cov Ntawv Qeb Qib ", tsab cai yog tus lej Pinyin)" H "sawv cev. Cov tooj dag zoo tib yam nrog "H" ntxiv rau cov ntsiab lus tooj liab, xws li: 68 tooj liab qhia ua H65, H62, tib lub laj thawj.
Tooj dag yeeb nkab nrog muaj zog, corrosion-resistant cov khoom, thiab ua tus neeg ua lag luam niaj hnub hauv ib lub tsev coj mus muag lub tsev nqa dej, cua sov, cua txias piping installation ntawm kev xaiv. Tooj dag cov yeeb nkab yog cov yeeb nkab dej zoo tshaj plaws.
Tooj dag cov kab ke:
Qhov hnyav dua, zoo thermal conductivity, siab lub zog ntawm tsawg kub. Feem ntau siv nyob rau hauv kev tsim cov tshav kub hloov khoom (xws li condensers, thiab lwm yam). Nws tseem siv rau kev sib sau ua ke tsawg-kub piping hauv cov khoom siv oxygen. Txoj hlab me me me me feem ntau siv nyob rau hauv cov kev thauj mus los ntawm cov pa roj carbon monoxide, roj li roj ntsha thiab lwm yam) thiab siv los ua qhov ntsuas ntsuas raj ntawm lub ntsuas.
Tooj dag raj zoo:
1, tooj liab yog nyiaj txiag. Vim tias tooj liab cov yeeb nkab yog yooj yim rau cov txheej txheem thiab txuas, tuaj yeem txuag cov ntaub ntawv thiab tag nrho tus nqi, muaj qhov zoo ruaj khov raws li kev ntseeg tau, tuaj yeem txuag kev tu siab.
2, tooj liab yog lub khaub lig. Rau tib lub inner inch ntawm stranded xov threased yeeb nkab, tooj dag yeeb nkab tsis xav tau cov tuab ntawm cov hlau ferrous. Thaum ntsia tau, tooj liab cov nqi tsheb kauj vab yog me dua, txij nkawm yog yooj yim dua thiab yuav siv sijhawm tsawg dua.
3. Tooj tuaj yeem hloov nws cov duab. Vim tias tooj liab cov yeeb nkab yuav tuaj yeem khoov thiab deformed, tooj liab hlau nws tuaj yeem ua rau tooj liab ua rau tooj liab yeeb mus khoov ntawm ib lub kaum sab xis.
4, tooj liab yooj yim txuas.
5, Tooj muaj kev nyab xeeb. Tsis muaj dej xau, tsis muaj nplaim, tsis muaj cov roj toxic, corrosion tsis kam. Tooj liab yeeb yog ib qho yooj yim, tsis yooj yim rau corrode, thiab tiv taus cov siab kub thiab kev kub siab, tuaj yeem siv ntau qhov chaw ib puag ncig.

Cov Khoom Siv Neeg Kho Tshuab thiab Kev Siv ntawm tooj dag hauv Brass Kev Ntsuam Xyuas
Tooj dag yog ib qho alloy muaj xws li tooj liab thiab zinc. Yog hais tias tsuas yog sau tooj liab thiab zinc brass yog hu ua tooj dag puas. Yog tias nws yog tsim ntawm ntau tshaj ob lub ntsiab ntawm ntau yam ntawm alloys yog hu ua tooj dag tshwj xeeb. Xws li cov hmoov txhuas, tin, manganese, npib tsib xee, txhuas, hlau, silicon tooj liab alloy. Tooj dag muaj zog hnav tsis kam. Kuj tseem tau hu ua tooj dag tshwj xeeb, uas muaj lub zog siab, tawv thiab tshuaj lom neeg kuj. Kuj tseem muaj cov khoom siv tshuab hluav taws xob muaj txiaj ntsig ntau dua. Lub raj plig tooj dag ntawm lub raj ntawm kev kos los ntawm tooj dag yog mos thiab muaj cov hnav muaj zog tiv taus. Seamless tooj dag cov leeg tuaj yeem siv rau cov kev sib pauv cua sov thiab cov hws, cryogenic piping, thiab undersea tsheb thauj cov hlab. Kev tsim khoom ntawm daim ntawv, sawb, bar, yeeb nkab, nrib feem thiab lwm yam. MUAJ NCOP HAUV 62% RAU 68% RAU 68%, Muaj Zog Yas, Raug Siab Siv Lub Siab-Resistant Khoom, Thiab Lwm Cov Khoom Siv ..
Raws li cov hom sib txawv ntawm cov ntsiab lus muaj nyob hauv tooj dag, tooj dag tau muab faib ua tooj dag zoo nkauj thiab tooj dag tshwj xeeb. Tooj dag rau lub siab ua yog hu ua deformed tooj dag.
Tooj dag yog lub tooj liab alloy nrog zinc raws li lub ntsiab additive cov khoom thiab muaj lub xim zoo nkauj, sib sau ua tooj liab. Tooj liab-zinc binary alloys yog hu ua tooj dag zoo nkauj lossis tooj dag yooj yim. Brasses nrog ntau tshaj peb cov ntsiab yog hu ua brasses tshwj xeeb lossis cov brasses. Tooj dag alloys muaj tsawg dua 36% zinc muaj cov kev daws teeb meem uas muaj cov khoom noj txias, feem ntau yog hu ua tooj dag ua tooj dag lossis xya-peb tooj dag. Tooj dag alloys muaj 36 txog 42% zinc muaj cov kev daws teeb meem thiab cov kev daws teeb meem feem ntau yog 40% zinc-muaj rau-plaub tooj dag. Txhawm rau txhim kho kev ua tau zoo ntawm tooj dag zoo tib yam, feem ntau ntxiv lwm cov ntsiab lus, ib yam li no, Npib, Manganese, Tin, silicon, txhuas thiab lwm yam. Aluminium tuaj yeem txhim kho lub zog, hardness thiab corrosion tsis kam ntawm tooj dag, tab sis cov yas yog txo, haum rau hiav txwv condenser lub raj thiab lwm qhov chaw condenser thiab lwm yam xeb-resistant seem. Tin tuaj yeem txhim kho lub zog ntawm tooj dag thiab corrosion tsis kam mus rau seawater, yog li hu ua Naval tooj dag, siv raws li lub nkoj cov khoom siv thermal thiab cov lus hais. Taug txhuas tuaj yeem txhim kho kev txiav tawm ntawm tooj dag; Qhov no hom ntawm cov tooj daj dawb yog feem ntau siv rau lub moos thiab saib qhov chaw. Tooj dag castings feem ntau siv los ua li qub thiab cov yeeb nkab fittings.
