Puas yog propane lom rau tib neeg?
Propane yog cov roj uas tsis muaj xim thiab tsis muaj ntxhiab tsw. Nws feem ntau yog siv los ua roj hauv ntau yam kev siv, suav nrog cua sov, ua noj, thiab lub zog tsheb. Txawm li cas los xij, kev txhawj xeeb tau tshwm sim txog qhov muaj peev xwm toxicity ntawm propane thiab nws cov teebmeem rau tib neeg kev noj qab haus huv. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov khoom ntawm propane, tshuaj xyuas nws cov kev pheej hmoo ntawm kev noj qab haus huv, thiab muab cov ntaub ntawv hais txog kev nyab xeeb thiab kev siv cov kev coj ua.
Txheej txheem cej luam ntawm Propane
Propane, nrog rau cov tshuaj formula C3H8, yog hydrocarbon gas. Nws yog muab los ntawm natural gas processing thiab petroleum refining. Cov pa roj uas kub heev no muaj nyob rau hauv cov kua hauv lub xeev nyob rau hauv lub siab siab los yog tsis kub. Propane tau siv dav vim nws cov ntsiab lus siab zog thiab kev txav mus los.
Lub cev muaj zog ntawm Propane
Propane yog ib qho roj ntawm tus qauv kub thiab siab (STP). Nws muaj qhov kub ntawm -42 degrees Celsius (-44 degrees Fahrenheit) thiab melting point ntawm -188 degrees Celsius (-306 degrees Fahrenheit). Nws qhov ceev yog kwv yees li 1.88 kg / m3 ntawm STP.
Ib qho ntawm cov khoom tshwj xeeb ntawm propane yog nws compressibility. Nws tuaj yeem khaws cia thiab thauj mus rau hauv cov ntaub ntawv ua kua hauv qab lub siab nruab nrab, ua kom yooj yim rau kev tswj thiab siv. Propane vaporizes sai sai thaum tso tawm rau hauv qhov chaw, rov qab mus rau nws lub xeev gaseous.
Toxicity ntawm Propane
Thaum xav txog cov tshuaj toxicity ntawm propane, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm qhov raug mob thiab mob ntev. Kev raug mob hnyav yog hais txog qhov raug luv luv, theem siab, thaum kis tau ntev yog hais txog qhov kis tau mus ntev, theem qis.
Mob toxicity
Propane suav hais tias muaj kev mob toxicity tsawg rau tib neeg. Kev nqus pa ntawm cov roj propane tuaj yeem ua rau ua pa me me, tab sis cov teebmeem feem ntau yog ib ntus thiab daws tau ib zaug uas raug tso tseg. Propane tsis paub tias yuav ua rau muaj kev puas tsuaj loj rau cov kabmob lossis cov ntaub so ntswg tom qab raug mob.

Kev tuav tsis raug lossis khaws cov propane tuaj yeem ua rau muaj kev phom sij, xws li hluav taws kub lossis tawg. Nws yog ib qho tseem ceeb kom ua raws li cov lus qhia kev nyab xeeb thiab siv propane nyob rau hauv qhov chaw muaj cua zoo kom txo tau qhov kev pheej hmoo ntawm kev sib tsoo.
Mob toxicity
Lub toxicity ntev ntawm propane rau tib neeg yog txwv. Tsis muaj kev tshawb fawb dav dav txog qhov cuam tshuam ntev ntawm kev raug propane. Txawm li cas los xij, raws li cov ntaub ntawv muaj, kev nqus tau ntev lossis kev sib cuag ntawm daim tawv nqaij nrog propane tsis xav tias yuav ua rau muaj teeb meem loj rau tib neeg.
Kev nyab xeeb thiab kev siv cov kev coj ua
Txhawm rau kom muaj kev nyab xeeb thiab siv cov propane, nws yog ib qho tseem ceeb uas yuav tsum ua raws li qee cov lus qhia. Nov yog qee cov lus qhia rau kev nyab xeeb siv propane:
1. Cia thiab qhov cua: Khaws cov propane cylinders upright nyob rau hauv ib tug zoo-ventilated cheeb tsam. Tsis txhob raug tshav ntuj ncaj qha thiab kub heev, vim tias cov propane cylinders tuaj yeem tawg thaum raug kub. Xyuas kom muaj qhov cua kom zoo thaum siv propane hauv tsev kom tsis txhob muaj cov pa roj.
2. Leak Detection: Propane tsis muaj ntxhiab tsw, tab sis muaj cov ntxhiab tsw hu ua ethyl mercaptan ntxiv los pab kom pom cov pa tawm. Yog tias koj hnov tsw muaj zog, tsis hnov tsw zoo ib yam li cov qe lwj, nws yuav qhia tau tias muaj propane los. Tshem tawm thaj chaw tam sim ntawd thiab hu rau cov kev pabcuam xwm txheej ceev.
3. Kev Nyab Xeeb Hluav Taws Xob: Khaws cov propane cylinders kom deb ntawm cov nplaim taws, cov khoom siv hluav taws xob, thiab qhov hluav taws kub. Tsis txhob haus luam yeeb ze ntawm lub tog raj kheej propane lossis siv cov propane ze cov khoom siv hluav taws xob. Thaum muaj hluav taws kub, khiav tawm ntawm thaj chaw thiab hu rau lub chaw tua hluav taws.
4. Cov Khoom Siv Kom Zoo: Tsuas yog siv cov khoom siv thiab cov khoom siv uas tsim los rau kev siv propane. Ua raws li cov chaw tsim khoom cov lus qhia rau kev teeb tsa, kev ua haujlwm, thiab kev saib xyuas cov khoom siv hluav taws xob propane.
