Yuav ua li cas txo tungsten xov hlau poob thaum lub sij hawm nqus thermal evaporation txheej txheej txheem

Xaiv annealed stress-relieved siab-purity tungsten twisted xov hlau (W Ntau dua los yog sib npaug rau 99.95%)

Txias-txheej txheem tungsten xov hlau uas tsis muaj kev cuam tshuam muaj kev ntxhov siab loj sab hauv. Tom qab siab -kub hluav taws xob, lawv yuav thim rov qab, deform, thiab cov coils yuav tawg, yooj yim plam tawm ntawm qhov khoom siv; Yog li ntawd, tsuas yog cov khoom tiav uas tau dhau los ua kev ntxhov siab dhau los yuav tsum tau xaiv rau cov xov hlau tungsten twisted.

Lub coil pitch yuav tsum ruaj khov, thiab cov xov hlau yuav tsum tsis txhob xoob ntawm qhov kub thiab txias.
◦ Nqus evaporation: Ntau -strand twisted xov hlau;
rau siab -load daim ntaub ntawv, xaiv tuab hlau inch thiab pob tawb coils (basket coil). Kev thauj khoom yog ruaj khov, thiab cov kua txhuas txhuas tsis tshua muaj dej.

◦ Tsis txhob siv cov xov hlau tungsten nrog cov ntsiab lus impurity siab: impurities ua rau cov chaw kub hauv zos, ua rau hauv zos thinning thiab nkig tawg.
 

Lub suab yuav tsum tsis txhob loj heev (aluminium melting yog nws ntog); Yog hais tias lub suab me me dhau, cov khoom txheej yog tuab heev, thiab thermal expansion kev nyuaj siab yog loj, ua rau cov chunks loj ntawm cov khoom tev tawm.

Kev tswj kom muaj nuj nqis: Tsis txhob thauj khoom tag nrho; qhov pom zoo loading npaum li cas yuav tsum tsis txhob ntau tshaj 60-70% ntawm twisted hlau lub peev xwm; Kev thauj khoom ntau dhau yuav ua rau cov hlau molten rub cov hlau sib tw, thiab tom qab txias, cov khoom yuav tsim ib pob thiab daim ntawv cog lus, ua rau cov tungsten hlau tawg thiab poob rau hauv cov khoom loj.

Lub fixture yuav tsum nyiam tantalum los yog molybdenum; Cov khoom siv tooj liab yuav muaj kev tiv thaiv tam sim ntawd tom qab siab -kub oxidation, ua rau lub zos overheating. Ntawm ib sab, nws yuav ablate qhov kawg ntawm tungsten hlau, thiab ntawm qhov tod tes, cov oxide txheej yuav plam, ua rau cov tungsten hlau detach thiab poob.

◦ Clamping quab yuam: Nruab nrab clamp, tsis txhob tsoo lub tungsten kawg quab yuam. Tungsten yog nkig heev ntawm chav tsev kub, thiab nias tawm micro- tawg yuav ua rau nws tawg ncaj qha; Tom qab lub voj voog thermal, nws yuav ncaj qha tawg;

◦ Clamping ntev: xyuas kom meej tias qhov kawg ntawm cov xov hlau txuas mus rau hauv lub fixture Loj dua lossis sib npaug li 3-5 hli, thiab qhov chaw clamping txaus; tsis txhob tsuas clamp me ntsis ntawm cov hlau kawg; tom qab siab -kub creep, nws yuav raug rub tawm thiab poob ncaj qha.

◦ Kev tshuaj xyuas: Txhua zaus thauj cov xaim, maj mam rub kom paub meej tias nws tsis swb; qhov chaw sib cuag ntawm lub fixture yuav tsum tau polished kom tshem tawm cov qub hlau deposits thiab oxide films.

Tungsten nthuav dav ntawm qhov kub thiab txias. Tsis txhob yuam kom nruj thiab ncaj nws. Khaws ib qho me me ntawm kev so thaum lub caij txias; Yog tias qhov txias txias yog nruj dhau, qhov nthuav dav ntawm qhov kub thiab txias yuav ua rau muaj kev ntxhov siab loj heev, ua rau nws tawg ncaj qha lossis rub tawm ntawm lub teeb.

5.Install txoj hauj lwm

Kab rov tav installation ntawm twisted hlau yog nyiam; lub kaum sab xis inclination yuav tsum tsis txhob loj dhau los tiv thaiv cov hlau molten los ntawm kev tsom mus rau ib sab, ua rau lub cev hnyav nce thiab rub lub kauj. Ib lub phaj molybdenum shielding los yog shielding board tuaj yeem muab ntxiv rau hauv qab ntawm cov xov hlau sib tw los tiv thaiv cov khoom los ntawm dripping thiab tiv thaiv lub substrate.
