Hlau thiab Metallurgical Plant Face Shield Thaum tshav kub kub & Splash Protection Guide
1. Hazard Spectrum
- Radiant heat: 25 kW/m² from 1,600 °C melt, >1,500℃splash dav hlau
- IR + sparks: TIG, plasma, oxygen lancing
- Plua plav & kua qaub: pickling, tua-blasting
2. Cov khoom yuav tsum-Muaj
- Lens: 2 hli polycarbonate + nano-cov tsho tiv no ceramic, qhia txog 88% IR, muaj sia nyob 30 s ntawm 900℃ncaj qha txaws.
- Ncej: 7075-T6 txhuas, T6-hardened, tsis muaj deformation ntawm -30℃lossis 250℃cycles.
- Ntug: Kevlar xov + stainless rivets, tiv thaiv ntug- hlawv- dhau tom qab 8,000 lub cub tawg.
- Foob: kho mob- qib silicone gasket, ASTM ntshav- nkag mus, -40℃rau +250℃elasticity.
3. Kev ntsuas kev ua tau zoo
- IR txo: 15℃ntawm tus neeg teb xov tooj lub ntsej muag, txiav cov cua sov- kev ntxhov siab tawg 12%.
- Kev cuam tshuam: ANSI Z87.1+ nruab nrab- cuam tshuam, 6 J steel- pob ntawm -5℃.
- Haum: bayonet mount, APF 1,000, nyem rau ntawm lub kaus mom hlau hauv<2 s.
4. Daim ntawv thov Matrix
- BOF converter – blocks 1,700℃radiant droplets.
- Foundry tapping – shields los ntawm slag chips + IR.
- Rolling-mill - tiv thaiv qhov kub tsis txias - nplai txaws.
5. Xaiv cov ntawv txheeb xyuas
✓ IR-paj rwb thaiv tsev ntau dua lossis sib npaug li 80%
✓ Kev ntsuas cuam tshuam ntau dua lossis sib npaug rau ANSI Z87.1+
✓ Edge Kevlar/stainless reinforcement
✓ Anti-Fog tawv tsho loj dua los yog sib npaug rau 1,000 h
✓ Bayonet mount compatibility
Qhov tshwm sim: lub visor uas hloov cov huab cua huab cua mus rau hauv kev tswj hwm, chaw ua haujlwm nyab xeeb, tsim los ntawm cov khoom uas tsis kam tawm los thaum tshav kub kub.
