Kev Siv Magnesium hauv Cartridge Heater Materials

Magnesium ua ntau ntau tshaj li insulate cartridge heaters. Ib qho ntawm nws txoj kev siv tseem ceeb yog ua tus neeg sawv cev txo qis hauv kev ua cov hlau uas tuaj yeem tiv taus qhov kub thiab txias. Nws yog siv kom tau txais cov hlau tsis tshua muaj xws li titanium, zirconium, thiab hafnium, nrog rau ua beryllium thiab boron.


Magnesium kuj tseem siv los ua tus neeg sawv cev alloying. Magnesium yog siv nyob rau hauv aluminium alloys kom lawv muaj zog thiab tiv taus corrosion. Ntxiv magnesium rau zinc tuag-casting alloys ua rau lawv muaj zog thiab ruaj khov rau qhov loj. Nws yog siv los ua cov khoom siv zinc ntxiv, xws li cov ntawv vov tsev, cov ntawv lithographic, zinc daim hlau rau cov roj teeb ntawm tes qhuav, thiab da dej galvanizing. Magnesium kuj ua rau npib tsib xee, npib tsib xee- tooj liab alloys, thiab tooj liab-nickel-zinc alloys ua haujlwm zoo dua.

Magnesium yog siv los ua cov hlau nplaum los ntawm kev ua nws nodular. Magnesium ua rau cam khwb cia hlau ntau zog thiab tawv dua los ntawm kev tshem tawm ib co sulfur thiab ua graphite loj hlob mus rau puag ncig nodules.

Tib neeg kuj siv magnesium ntau heev los tshem cov sulfur ntawm hlau. Magnesium yog ib txoj hauv kev zoo los tshem tawm cov pa oxygen thiab roj los ntawm cov hlau alloy xws li tooj dag thiab tooj liab, nrog rau los ntawm cov nickel alloys. Lub Betterton-Krol txheej txheem rau purifying lead siv calcium thiab magnesium ua ke kom tshem tawm bismuth.

Magnesium kuj tseem siv los ua cov alkyl thiab aryl compounds uas ua rau cov neeg ua haujlwm tsis zoo hauv cov roj lubricating. Nws yog siv los ntxuav argon thiab hydrogen gases. Magnesium yog siv los ua ib qho khoom siv hauv kev ua cov raj nqus tsev. Nws kuj tseem siv los ua boron hydride, lithium hydride, thiab calcium hydride. Nws kuj yog siv los tshem tawm cov pa oxygen thiab chlorine los ntawm boiler pub dej.

Magnesium yog ib yam khoom zoo rau khaws cia ntau lub zog. Thaum magnesium thiab hydrogen tuaj rau hauv kev sib cuag ntawm ib txwm siab thiab ntawm 523K, lawv tsim magnesium hydride (MgH₂). Nws tso tawm hydrogen thaum lub siab qis lossis qhov kub thiab txias me ntsis. Magnesium tuaj yeem tuav hydrogen, thiab MgH₂ tuaj yeem tuav lub zog ntau dua li lwm cov hlau hydrides. Qhov no ua rau magnesium yog cov khoom siv zoo rau khaws cia lub zog ntawm qhov ntom ntom.

Magnesium tau siv rau hauv cov foob pob hluav taws tau ntev. Thaum hlawv, magnesium- aluminium alloy zoo hmoov nrog ntau tshaj 30% aluminium muab lub teeb ci heev. Vim hais tias ntawm no feature, magnesium yog thawj zaug siv nyob rau hauv kev lag luam rau cov khoom siv teeb pom kev zoo li lub koob yees duab flashbulbs. Magnesium hmoov kuj tseem siv rau hauv cov mos txwv taug qab rau kev yees duab huab cua hmo ntuj, ntau cov foob pob hluav taws, siab - roj hluav taws xob, thiab cov khoom tawg. Ntshiab magnesium tsis muaj zog txaus siv los ua cov khoom siv vim nws tsis muaj zog. Txawm li cas los xij, cov yam ntxwv ntawm magnesium tuaj yeem txhim kho tau zoo los ntawm kev siv cov txheej txheem xws li kev ua haujlwm hardening, grain refinement, alloying, heat treatment, thiab composite creation with ceramic phases, los yog los ntawm kev sib txuas cov tswv yim. Alloying yog qhov yooj yim tshaj plaws, nthuav dav, thiab ua tiav txoj hauv kev ua kom muaj zog hauv lub neej tiag tiag.
