Hlau "melting" feem ntau yog hais txog qhovmelting thiab hlawv ntawm rwb thaiv tsev. Cov tub ntxhais tooj liab melts tsuas yog nyob rau hauv qhov tsis ncaj ncees lawm nrog lub melting point ntawm 1083 degree. Tag nrho cov kev ua tsis tiav yog tshwm sim los ntawm lub zog hluav taws xob hauv zos (Joule's Law).
Peb Qhov Tseem Ceeb
1. luv Circuit Court: Kev sib cuag ntawm cov nyob, nruab nrab lossis hauv av xaim ua rau muaj kev kub ntxhov tam sim no thiab ultra-siab- kub arcs (tshaj 3000 degree) uas hlawv cov xov hlau tam sim ntawd.
2. Tshaj dhau: Kev siv ntau dhau - cov khoom siv hluav taws xob ntau dhau ntawm cov xaim muaj kev nyab xeeb tam sim no. Thaum tshav kub kub tshaj 250℃melts thiab ignites lub rwb thaiv tsev.
3. Kev sib cuag tsis zoo: Cov pob qij txha xoob lossis oxidized nce hauv zos tsis kam, ua rau muaj kev kub ntxhov siab thiab xaim ablation.
Risk Accelerators: Circuit Court aging, irregular wiring, undersized nyob ntawm tej, sab nrauv puas, ya raws thiab corrosion.
Warning Signs (Power off tam sim ntawd): Hlawv roj hmab tsis hnov tsw, nplaum / tsis muaj xim hlau sheath, txawv txav kev sib koom ua ke, nquag tripping.
