Tungsten phaj

Tungsten muaj qhov siab tshaj plaws melting point ntawm tag nrho cov hlau thiab muaj cov tshuaj lom neeg ruaj khov. Nws lub siab hardness thiab siab ceev ua rau nws nyuaj heev rau txheej txheem. Lub phaj tungsten yog tsim los ntawm cov hmoov hlau metallurgy, siv cov hmoov tungsten zoo, ua tiav rau hauv cov nplais nrog kev ua haujlwm zoo, thiab tom qab ntawd tsim los ntawm cov cuab yeej tshwj xeeb dov. Tom qab pickling los yog alkali ntxuav, nto yuav tshwm steel grey los yog nyiaj dawb. Tungsten phaj dov tuaj yeem muab faib ua kub dov, sov dov thiab txias dov, thiab nws qhov chaw yog du thiab tiaj, tsis muaj daim tawv nqaij tuab, tsis muaj delamination thiab tawg, tsis muaj impurity inclusions, thiab lwm yam. Cov ntsiab lus tungsten ntawm tungsten phaj yog siab li 99.95. %, uas suav nrog tag nrho cov yam ntxwv thiab qhov zoo ntawm tungsten, xws li muaj zog corrosion kuj, zoo kub oxidation tsis kam, siab hnav tsis kam, kub kub zog, zoo electron emission kev ua tau zoo, tsis tshua muaj thermal expansion coefficient thiab kev ua tau zoo. Nws cov khoom siv tshuab feem ntau yog txiav txim siab los ntawm lub xeev ntawm kev ua haujlwm siab thiab kev kho cua sov.

Vim nws cov hardness siab, siab melting point thiab muaj zog hluav taws xob nqus muaj peev xwm, tungsten phaj tuaj yeem siv los ua cov khoom siv raw rau cov khoom siv hluav taws xob tiv thaiv hluav taws xob, cov ntaub thaiv hluav taws xob thiab lwm yam khoom siv hluav taws xob los yog hluav taws xob resistant. Tungsten daim hlau yog dav siv hauv tshuab hluav taws xob, kev kho mob, aerospace, tshuaj, machinery, zog tshiab, metallurgy thiab lwm yam lag luam. Piv txwv li:

1. Hauv kev lag luam metallurgical, tungsten daim hlau tuaj yeem siv los ua cov khoom siv raw rau kev tsim cov nkoj tungsten lossis molybdenum nkoj, thiab siv rau hauv kev tsim cov khoom cua sov, cov khoom siv hluav taws xob thiab cov khoom siv refractory nyob rau hauv high-temperature furnaces, thiab kuj siv tau rau hauv ion. implantation cathodes thiab anodes, sputtering thiab txheej.

2. Nyob rau hauv kev lag luam kev kho mob, tungsten phaj yog siv los ua raw khoom ntawm hluav taws xob shielding screen, uas yuav siv tau nyob rau hauv kev kho mob CT, kuaj cov khoom, radioactive syringes, thiab lwm yam.

3. Hauv kev lag luam hluav taws xob thiab hluav taws xob, tungsten daim hlau tuaj yeem siv los tsim hluav taws xob lub teeb qhov chaw, hluav taws xob lub tshuab nqus tsev, semiconductor substrates, electron tube sib dhos, electron beam evaporation cathodes thiab cov ntaub ntawv photosensitive, thiab lwm yam.
