Nta ntawm r152a tub yees:
Tus nqi ODP ntawm R152a yog xoom, thiab GWP tsuas yog me me, uas yog 0.023.
R152a muaj tus qauv boiling point ntawm -25 degree thiab lub freezing point ntawm -117 degree, uas yog superior rau R12 nyob rau hauv lub tub yees lub voj voog yam ntxwv.
R152a muaj peev xwm ua kom txias dua rau ib chav tsev ntim thiab lub zog ua kom muaj zog dua li R12 thiab R134a.
Lub viscosity ntawm R152a tsis txawv ntau ntawm R12, tab sis qhov tshwj xeeb kub muaj peev xwm thiab latent cua sov ntawm vaporization ntawm cov kua thiab roj yog loj dua li ntawm R12, thiab cov thermal conductivity ntawm roj thiab kua yog ho siab dua li ntawm R12.
Thaum siv R152a, yuav tsum muaj kev ntsuas kev nyab xeeb zoo; yuav tsum tau siv lub tshuab nqus dej tshwj xeeb rau R152a; Thaum siv cov kua ua haujlwm sib xyaw, cov khoom siv hluav taws xob halogen yuav tsum rov ntsuas dua.
R152a yog siv los ua cov khoom siv tseem ceeb rau tus neeg sawv cev foaming, aerosol, tu tus neeg saib xyuas thiab polyvinylidene fluoride.
Lub viscosity ntawm R152a tsis txawv ntau ntawm R12, tab sis qhov tshwj xeeb kub muaj peev xwm thiab latent cua sov ntawm vaporization ntawm cov kua thiab roj yog loj dua li ntawm R12, thiab cov thermal conductivity ntawm roj thiab kua yog ho siab dua li ntawm R12.
R152a yog flammable thiab yuav ntes hluav taws thaum nws ntim feem hauv huab cua mus txog 4-17 feem pua .
Kev kho mob xwm txheej ceev ntawm r152a refrigerant
Ceev nrooj khiav tawm cov neeg ua haujlwm nyob rau hauv qhov chaw paug paug mus rau qhov chaw siab, thiab cais lawv, nruj me ntsis txwv kev nkag mus. Txiav tawm qhov hluav taws kub. Nws raug pom zoo tias cov neeg ua haujlwm xwm txheej ceev yuav tsum hnav lub tshuab ua pa zoo rau tus kheej thiab cov khaub ncaws tiv thaiv hluav taws. Txiav tawm qhov chaw ntawm cov xau kom ntau li ntau tau. Npog qhov chaw xws li cov kav dej ze ze ntawm qhov xau nrog lub hau npog lossis nqus / nqus kom tsis txhob muaj roj nkag mus. Tsim nyog qhov cua, ua kom lub diffusion. Dilute thiab yaj nrog tshuaj tsuag dej. Tsim cov dikes lossis khawb qhov kom muaj cov dej khib nyiab ntau. Yog tias ua tau, xa cov roj xau mus rau qhov chaw qhib nrog lub kiv cua los yog nruab lub nozzle tsim nyog los hlawv nws. Nws tuaj yeem raug coj mus rau qhov cub nrog cov kav dej thiab hlawv hauv kev nyuaj siab. Cov thawv ntim dej yuav tsum tau muab pov tseg kom zoo, kho thiab tshuaj xyuas ua ntej rov siv dua.
Kev tiv thaiv
Kev tiv thaiv kab mob ua pa: Feem ntau, tsis tas yuav tsum muaj kev tiv thaiv tshwj xeeb, thiab feem ntau tsis tas yuav tsum muaj kev sib xyaw ua ke, tab sis nws raug nquahu kom hnav lub npog ntsej muag roj rau tus kheej (ib nrab daim npog ntsej muag) nyob rau hauv qhov xwm txheej tshwj xeeb.
Kev Tiv Thaiv Qhov Muag: Hnav cov tsom iav tiv thaiv tshuaj lom neeg thaum tsim nyog.
Kev tiv thaiv lub cev: hnav anti-static zuag qhia tag nrho.
Kev tiv thaiv tes: hnav hnab looj tes tiv thaiv ua haujlwm.
Lwm tus: Kev haus luam yeeb yog txwv tsis pub nyob hauv chaw ua haujlwm. Ua hauj lwm hauv cov tso tsheb hlau luam, qhov chaw txwv lossis lwm qhov chaw siab siab yuav tsum tau saib xyuas los ntawm ib tus neeg.
kev pab thawj zaug
Inhalation: Ceev nrooj tawm ntawm qhov chaw mus rau huab cua ntshiab. Khaws txoj hauv kev qhib. Yog ua pa nyuaj, muab cov pa oxygen. Yog tias tsis ua pa, muab kev ua pa tawm tam sim ntawd. Nrhiav kev kho mob.
Txoj kev tua hluav taws: txiav tawm cov pa roj. Yog tias qhov hluav taws xob tsis tuaj yeem raug txiav tawm tam sim ntawd, nws tsis raug tso cai kom tua cov roj hlawv. Txias lub thawv nrog dej tsuag, txav lub thawv los ntawm hluav taws mus rau qhov chaw qhib yog tias ua tau.
Extinguishing media: dej pos huab, ua npuas ncauj, carbon dioxide, hmoov qhuav.
