Graphite-coated tungsten hlau
Thaum lub sij hawm xaim txheej txheem, graphite lubricant yog adhered rau saum npoo, uas yog ib tug tshwj xeeb lubrication thiab tiv thaiv txheej txheem rau daim duab. Yog li ntawd, tag nrho cov hlau zoo li dub.
Raws li lub teb chaws tus qauv GB/T 4181-2017, dub tungsten hlau tsuas yog qhov txawv ntawm plaub lub npe tseem ceeb: ntshiab tungsten qib W1/W2 thiab doped non-sagging tungsten xov hlau WAL1/WAL2. Cov xim dub ntawm qhov chaw tsuas yog cov graphite lubrication txheej thaum lub sij hawm xaim kos duab thiab tsis hloov cov ntsiab lus ntawm lub hauv paus hlau.

Qhov zoo ntawm Dub Tungste hlau (Graphite-Coated Tungsten Hlau)
Kev ua haujlwm zoo heev thiab kev ua haujlwm zoo, Cov nplaim graphite emulsion ua haujlwm raws li cov roj nplua nyeem, ua rau khoov, sib tw, winding coils, thiab hlau kos duab tsis tshua muaj kev tawg lossis tawg. Cov txiaj ntsig ntawm kev kos duab thiab winding yog ntau dua li qhov ci thiab whitened tungsten hlau.
Luv luv -lub sij hawm oxidation tsis kam, Lub nto graphite cais tawm ntawm huab cua, tiv thaiv oxidation thiab yellowing ntawm chav tsev kub. Nws tsis yog yuav tsum tau siv kev tiv thaiv tshwj xeeb thaum khaws cia, txiav, thiab tuav.
Tus nqi qis dua, Tsis muaj cov txheej txheem ntawm alkaline ntxuav, electrolytic polishing thiab graphite tshem tawm, chav tsev nqi pheej yig dua li cov tungsten hlau, thiab nws yog tus nqi ntau dua -zoo rau kev ua haujlwm loj -.
Qhov kev ua tau zoo ntawm qhov kub thiab txias tseem tsis hloov pauv, Lub ntsiab lus tseem ceeb ntawm qhov kub thiab txias (3422 degree) ntawm tungsten hlau, qis creep ntawm qhov kub thiab txias, ruaj khov thiab lub zog siab yog khaws cia.
Smooth vuam thiab winding, Lub graphite lubrication txheej txo qhov hnav ntawm cov pwm, thiab cov khoom siv winding poob qis dua.
Qhov tsis zoo ntawm Dub Tungsten Hlau
Nws yooj yim rau cov pa roj carbon monoxide thiab paug cov khoom ua haujlwm nyob rau hauv qhov chaw siab - qhov kub thiab txias.
Thaum rhuab nyob rau hauv ib puag ncig huab cua, qhov chaw graphite yuav hlawv thiab poob tawm, tsim carbon hmoov. Qhov no tuaj yeem cuam tshuam cov txheej txheej txheej thiab cov phab ntsa sab hauv ntawm lub teeb lub raj thaum lub sijhawm txheej txheej thiab precision lub teeb qhov chaw tsim khoom. Cov khoom tiav lawm yuav tsum muaj cov pa roj carbon tshem tawm.
Tsis zoo conductivity thiab reflectivity
Cov graphite txheej muaj qhov tsis muaj zog conductivity thiab tsis haum rau ncaj qha ua precision conductive Cheebtsam lossis cov ntsiab lus cuam tshuam. Nws yuav tsum tau muab ntxuav ua ntej siv.
Cov txheej txheej saum npoo yog yooj yim rau detachment thiab kev sib kis ntawm kev cob qhia.
Thaum txiav thiab winding, graphite dub hmoov zoo li yuav poob rau ntawm cov khoom siv thiab cov khoom. Yuav tsum muaj txheej txheem tshem tawm plua plav ntxiv nyob rau hauv qhov kev cob qhia ua haujlwm.
Nws tsis tuaj yeem siv ncaj qha rau siab -precision optical / siab-kawg teeb qhov muag khoom tiav.
Lub xub ntiag ntawm graphite residues tuaj yeem ua rau fogging ntawm txheej thiab blackening ntawm lub teeb. Tom qab tsim cov txheej txheem, ntxiv alkali ntxuav thiab electrolytic tu txheej txheem yuav tsum tau ntxiv, ua rau cov nqi ua.
Lub sijhawm ntev - siv nyob rau hauv lub tshuab nqus tsev siab thiab qhov kub thiab txias yuav tso tawm impurities.
Nyob rau hauv lub tshuab nqus tsev siab thiab ultra-qhov kub thiab txias, cov graphite maj mam volatilizes, cuam tshuam rau lub tshuab nqus tsev℃thiab purity ntawm txheej. Siab -kawg kho qhov muag evaporation nyiam siv cov tungsten hlau ntxuav.
Ntim txoj kev
1. Fine Wire: φ Tsawg dua lossis sib npaug li 0.35mm (350μm, 0.02 - 0.35mm, coated filament, ultra-fine heating wire)
Dub tungsten hlau rau ntawm cov yas spool
Txheem: Dawb ABS yas spool; Qhov me me spool yog tsim rau 0.02 - 0.1mm ultra-fine hlau, loj phaj spool yog haum rau 0.1 - 0.35mm.
Tib -axis tiv thaiv cov kauj ruam:
① Cov tungsten hlau thaiv yog zoo huv si, thiab cov hlau xaus yog tsau nrog clips los tiv thaiv cov xov hlau xoob;
② qhwv lub ntsej muag nrog waxed los tiv thaiv- daim ntawv ya raws los tiv thaiv graphite dub hmoov tsis poob thiab tiv thaiv los ntawm ya raws;
③ Muab ib qho -axis nyob rau hauv ib puag ncig lub raj yas / square ntawv lub thawv, thiab muab cov desiccant rau hauv lub raj;
④ Rau ntau-axis stacking, siv cov khoom ua npuas ncauj cais lawv, tiv thaiv kev sib txhuam thiab khawb ntawm cov xov hlau thiab kom tsis txhob khawb cov graphite txheej.
2. Coarse Hlau: φ > 0.35mm (0.4 - 3.0mm, cua sov xaim rau siab- kub rauv, tungsten twisted hlau raw khoom)
Loj txoj kab uas hla tungsten hlau kauj
Cua mus rau hauv lub voj voog tsis tu ncua, tsis txhob ntswj hauv 8 duab;
Txhua kauj yog tsau nrog cov hlau mos / nylon cable ntawm 3 - 4 cov ntsiab lus;
Tag nrho cov pob yog nruj nreem qhwv nrog ntau- txheej ya raws- ntawv pov thawj kraft ntawv + PE yas zaj duab xis los tiv thaiv graphite plua plav los ntawm cov khoom ntim sab nraud.
Lub hnab yog uniformly muab tso rau hauv lub desiccant, lub dub tungsten hlau graphite txheej absorbs noo noo thiab yog nquag mus rau hmoov los, tiv thaiv ya raws yog qhov tseem ceeb.
