Cov phom sij txaus ntshai yog qhov phom sij ntawm qhov kub hnyiab ntawm lub cev: Sparks tuaj yeem ya mus rau khau lossis qhov muag thiab ua rau raug mob. Txhawm rau tiv thaiv lub cev los ntawm cov nplaim taws, cov vuam yuav tsum hnav cov caj dab siab, tsis tshua muaj hluav taws xob tiv thaiv khaub ncaws, hnab looj tes tiv thaiv tawv thiab lub kaus mom hlau vuam.
Tseem ua rau koj raug mob?
Tswb tsaws rau koj daim tawv nqaij lossis khaub ncaws tsis zoo li yuav ua rau muaj kev puas tsuaj tiag tiag. Txawm li cas los xij, qhov no tsis tau txhais hais tias lawv tsis muaj teeb meem kiag li. Thaum lub txim taws yuav tsis kub txaus los hlawv koj txhais tes lossis lwm qhov chaw uas cov tawv nqaij tuab, cov tawv nqaij rhiab tuaj yeem pom cov nplaim taws ua rau mob.
Tau taws hlawv?
Sparks los ntawm welder txawv me ntsis. Lawv yog cov me me ntawm cov hlau blasted tawm ntawm qhov chaw ntawm kev sib cuag ntawm ob hlau (hauv electrowelding). Txawm li cas los xij, lawv tsis tau txhais hais tias hlawv thiab tsim teeb. Lub teeb uas koj pom yog hluav taws xob tawm ntawm cov hlau me me vim nws qhov kub thiab txias.
Lub kaum ntse ntse qhov ci txaus ntshai npaum li cas?
Piv txwv li, yog tias koj siv lub kaum sab xis nyob ze ntawm qhov chaw nres tsheb refueling, los yog ze rau ntawm qhov chaw cia lossis siv cov khoom siv hluav taws xob lossis cov khoom tawg, koj tab tom tsim phom sij thiab tawg. Yog tias muaj cov khoom siv hluav taws kub hauv qhov chaw ua haujlwm, lawv tuaj yeem ntes hluav taws los ntawm cov nplaim taws.
Yuav ua li cas welding txim ua rau hluav taws?
Lub txim taws thiab tshem tawm ntawm cov hlau molten uas tsim los ntawm vuam thiab txiav cov txheej txheem yog npaj txhijqhov chaw ntawm qhov hluav taws kub uas tuaj yeem mus txog 35 ko taw (10 meters) los ntawm lawv qhov chaw. Vim tias cov nplaim taws tuaj yeem mus deb, txhua yam cov khoom siv hluav taws xob hauv thaj chaw tam sim tuaj yeem ua rau muaj hluav taws kub hnyav.

Cov kua dej twg yog cov nplaim taws?
Flammable: Cov kua uas muaj lub teeb nyem hauv qab 100 ° F yog suav tias yog nplaim taws. Piv txwv li: roj av, acetone, toluene, diethyl ether, cawv. Yuav ua li cas yog cov nplaim taws tshaj plaws? 1) Chlorine Trifluoride yog cov pa hluav taws kub tshaj plawsNtawm tag nrho cov tshuaj lom neeg txaus ntshai, chlorine trifluoride paub tias yog cov nplaim hluav taws kub tshaj plaws.
Puas cybex siv cov nplaim hluav taws xob?
(FYI, Cybex Aton 2 kuj muaj cov ceg thauj khoom thiab yog Car Seat Lady nyiam. Nws muaj ntau dua cov nplaim hluav taws kub hnyiab ho.) Lub tsheb twg tsis muaj hluav taws kub? Cov khoom lag luam ua hluav taws kub tsis muaj lub rooj zaum hauv tsheb yog:
Cov neeg tua hluav taws puas siv cov nplaim taws?
California cov neeg tua hluav taws siv cov hluav taws kub hnyiab hauv San Gabriel Toj siab rov qab hlawv cov av hauv txoj kev ntawm Bobcat hluav taws. Cov neeg tua hluav taws puas siv hluav taws? Cov neeg tua hluav taws tswj qhov hluav taws kub sib kis (lossis muab tso tawm) los ntawm kev tshem tawm ib qho ntawm peb cov khoom xyaw hluav taws kub uas yuav tsum tau hlawv:
Vim li cas cov resins yog nplaim taws?
mas cua. Cov vapors tuaj yeem tsim cov khoom tawg nrog cua. Qee cov resins tej zaum yuav muaj unsaturated ob daim ntawv cog lus uas polymerize explosively thaum rhuab los yog koom nyob rau hauv hluav taws. Saturated aliphatic hydrocarbons, uas muaj nyob rau hauv RESIN COMPOUND, tej zaum yuav incompatible nrog muaj zog oxidizing neeg sawv cev zoo li nitric acid.
Puas ntxaib nplaim taws kev sib raug zoo?
Kev sib raug zoo tej zaum yuav xav tias yog hom kev sib raug zoo, vim nws yog kev sib txuas ntawm ob tus ntsuj plig, txawm tias nws txawv ntawm cov nplaim taws los yog tus ntsuj plig uas kho tau hauv xwm. Zoo tshaj qhov tsis yog, peb txhua tus yuav muaj ib qho ntawm cov kev sib raug zoo no hauv peb lub neej.
