Lub ntsiab hom thiab daim ntawv thov yam ntxwv ntawm tooj dag tshwj xeeb
Cov tooj dag tshwj xeeb yog tooj dag tau los ntawm kev ntxiv cov hlau alloy xws li txhuas, txhuas, tin, manganese lossis npib tsib xee rau tooj dag yooj yim. Nws yog hu ua aluminium brass, lead brass, tin brass, manganese brass, nickel yellow Copper thiab lwm yam. Nws feem ntau muaj qee yam khoom tshwj xeeb, xws li txhuas txhuas muaj kev ua haujlwm zoo, tin tooj dag muaj corrosion kuj zoo, thiab lwm yam. Raws li cov zinc sib npaug. , qhov tseeb zinc cov ntsiab lus ntawm cov tooj dag tshwj xeeb tuaj yeem suav nrog, thiab nws cov qauv tuaj yeem txiav txim raws li.
Kev siv tseem ceeb thiab cov yam ntxwv ntawm cov tooj dag tshwj xeeb:
Tin tooj dag: Tin tooj dag tuaj yeem txhim kho qhov corrosion kuj ntawm tooj dag hauv dej hiav txwv, huab cua thiab dej hiav txwv, thiab tuaj yeem txhim kho lub zog ntawm tooj dag. Nias tin tooj dag yog siv dav hauv kev tsim cov nkoj nkoj nkoj.
Lead Brass: Lead txhim kho machinability thiab hnav tsis kam. Lead tsis tshua muaj kev cuam tshuam rau lub zog ntawm tooj dag, thiab nws cov plasticity yog me ntsis txo. Xovxwm-txheej txhuas tooj dag yog tsuas yog siv rau qhov chaw uas yuav tsum tau zoo machinability thiab hnav tsis kam (xws li watch qhov chaw), thiab cam khwb cia txhuas tooj dag siv tau los ua bearings thiab bushings.
Aluminium Brass: Aluminium tsub kom lub zog thiab hardness ntawm tooj dag, tab sis txo nws cov plasticity. Aluminium tuaj yeem tsim cov yeeb yaj kiab tiv thaiv oxide rau ntawm qhov chaw ntawm tooj dag, yog li ua kom muaj zog ntawm tooj dag nyob rau hauv qhov chaw. Aluminium tooj dag tuaj yeem siv los ua cov khoom tiv thaiv corrosion rau cov nkoj nkoj nkoj thiab lwm yam tshuab. Ntxiv cov nqi tsim nyog ntawm npib tsib xee, manganese thiab hlau rau txhuas tooj dag tuaj yeem tsim cov tooj dag tshwj xeeb uas muaj lub zog siab thiab muaj zog corrosion, uas feem ntau yog siv los ua cov cab loj, cov nkoj nkoj hiav txwv thiab lwm yam khoom uas yuav tsum tau muaj zog thiab corrosion kuj. Qhov tseem ceeb.
Silicon tooj dag: Silicon tooj dag tuaj yeem txhim kho cov khoom siv dag zog, hnav tsis kam thiab corrosion kuj ntawm tooj dag. Silicon tooj dag muaj cov khoom zoo casting thiab tuaj yeem welded thiab ua tiav. Feem ntau yog siv nyob rau hauv kev tsim cov nkoj thiab tshuaj machinery qhov chaw.
Manganese tooj dag: Manganese tuaj yeem ua kom lub zog ntawm tooj dag tsis txo nws cov plasticity, thiab tuaj yeem txhim kho corrosion kuj ntawm tooj dag nyob rau hauv seawater thiab superheated chav. Manganese tooj dag feem ntau yog siv los ua qhov hnav-tiv taus xws li marine nkoj qhov chaw thiab bearings.
Hlau tooj dag: Ntxiv cov hlau rau tooj dag thiab ntxiv ib qho me me ntawm manganese tuaj yeem ua rau qhov kub thiab txias ntawm cov tooj dag tuaj yeem ua kom zoo dua cov nplej, txhim kho cov khoom siv kho tshuab, thiab tib lub sijhawm ua rau tooj dag muaj qhov tawv tawv, hnav tsis kam thiab ua haujlwm rau atmospheric thiab seawater. muaj kev tiv thaiv corrosion zoo heev, yog li hlau tooj dag tuaj yeem siv los ua cov khoom cuam tshuam los ntawm kev sib txhuam thiab dej hiav txwv corrosion.
