Yuav ua li cas kom paub qhov tseeb ntawm molybdenum hlau seem
Feb 04, 2024
Khib molybdenum hlau vim hais tias chav tsev nqi kuj yog siab, nyob rau hauv cov txheej txheem rov ua dua yog feem ntau yuav tshwm sim fake, adhered nrog lwm yam tshuaj, thiaj li yuav tiv thaiv tau kev dag ntxias, tswv lub cim ntawm pov tseg molybdenum hlau yog heev tsim nyog, cov nram qab no kev taw qhia ntawm ob peb txoj kev. txhawm rau txheeb xyuas qhov tseeb.
1, vim hais tias molybdenum hlau melting point yog siab, mus txog rau ntau tshaj 2,500 degrees, rub qhib los ntawm txhais tes (tsis tas yuav tsum nruj heev) nrog ib tug hluav taws kub combustion engine, qhov tsawg kawg nkaus ntawm ib tug kaum vib nas this los hlawv, yog 10 vib nas this. los rhuav tshem yeej rau qhov cuav. Thiab fakes feem ntau tawg nyob rau hauv ib pliag nrog sparks.
2, molybdenum hlau tsis sib nqus, nrog cov hlau nplaum muaj zog tsis nqus hlau nplaum. Yog li siv cov hlau nplaum los nqus cov hlau molybdenum, nqus rau qhov cuav.
3, lub molybdenum hlau knotted thiab nruj, (tsis txhob rub tawm) thiab tom qab ntawd loosened, koj yuav pom cov molybdenum hlau cais ob lossis ntau dua.
4, ib lub pob ntawm molybdenum xaim mus rau lub qhov cub roj ntawm lub qhov cub, ib feeb lossis kom tshem tawm, cov hlau molybdenum sai sai oxidized rau hauv xiav.
5, ib tug molybdenum hlau, ncuav ib co concentrated nitric acid cia tam sim ntawd ntab daj pa luam yeeb. (Thov ceev faj nrog txoj kev no, vim hais tias cov ntsiab lus nitric acid yog corrosive heev)
6, nyob rau hauv lub dov mus rau hauv ib lub pob ntawm cov khib nyiab molybdenum hlau, yog tias koj xav tias qhov hnyav hnyav dhau lawm, tej zaum yuav raug tov nrog hlau, khaws cov hlau molybdenum mus rau hauv av, yog tias muaj ib qho khoom nyuaj kov hauv pem teb ntawm lub suab, uas yog, tej zaum yuav muaj hlau nyob nruab nrab. Rolled rau hauv ib lub pob ntawm molybdenum hlau, yog hais tias lub extrusion elasticity tsis zoo, tej zaum yuav muaj ntaub nyob rau hauv nruab nrab, thiab lwm yam, yuav tsum tau disassembled rau kev soj ntsuam.
7, tsis txhob sab nraum cov khib nyiab ntawm molybdenum xaim nrog ntau cov roj hnyav, roj, thiab lwm yam., yuav tsum yog luv nqi.
