Txoj Cai
Nyob rau hauv xyoo tas los no, muaj kev txhawj xeeb ntau ntxiv txog ib puag ncig thiab kev noj qab haus huv txaus ntshai los ntawm halogen-raws li nplaim hluav taws siv hauv cov yas.Raws li qhov tshwm sim, cov nplaim hluav taws tsis muaj halogen tau txais kev nyiam vim lawv cov yam ntxwv zoo dua thiab ruaj khov dua.
Halogen-dawb nplaim retardants ua haujlwm los ntawm kev cuam tshuam cov txheej txheem combustion uas tshwm sim thaum cov yas raug hluav taws kub.
1.Lawv ua tiav qhov no los ntawm lub cev thiab tshuaj lom neeg cuam tshuam nrog cov nplaim hluav taws xob tso tawm thaum lub sij hawm combustion.Ib qho ntawm cov txheej txheem sib xws yog los ntawm kev tsim cov txheej txheem tiv thaiv carbon ntawm cov yas.
2. Thaum raug tshav kub, cov nplaim hluav taws tsis muaj halogen muaj cov tshuaj tiv thaiv, uas tso dej los yog lwm yam roj uas tsis yog hluav taws kub.Cov pa roj carbon monoxide no tsim ib qho kev thaiv ntawm cov yas thiab cov nplaim hluav taws, yog li ua kom cov hluav taws sib kis qeeb.
3. Cov nplaim hluav taws tsis muaj halogen decompose thiab tsim cov txheej txheem carbonized ruaj khov, hu ua char, uas ua rau lub cev tsis muaj zog, tiv thaiv kev tso tawm ntawm cov pa roj carbon monoxide ntxiv.
4. Tsis tas li ntawd, halogen-dawb nplaim retardants tuaj yeem dilute cov combustible gases los ntawm ionizing thiab ntes cov dawb radicals thiab volatile flammable Cheebtsam.Cov tshuaj tiv thaiv no ua rau cov saw hlau cov tshuaj tiv thaiv ntawm combustion, ntxiv txo qhov kev siv ntawm hluav taws.
Ammonium polyphosphate yog phosphorus-nitrogen halogen-dawb nplaim taws retardant.Nws muaj cov nplaim hluav taws kub retardant kev ua tau zoo hauv cov yas uas tsis muaj tshuaj lom thiab ib puag ncig.
Daim ntawv thov yas
Cov nplaim hluav taws kub hnyiab zoo li FR PP, FR PE, FR PA, FR PET, FR PBT thiab lwm yam yog feem ntau siv hauv kev lag luam tsheb rau tsheb sab hauv, xws li dashboards, qhov rooj vaj huam sib luag, rooj zaum, hluav taws xob enclosures, cable tais, hluav taws kub. hluav taws xob panels, switchgears, hluav taws xob enclosures, thiab thauj cov dej, gas pipes
nplaim retardant txuj (UL94)
UL 94 yog cov khoom siv hluav taws xob hluav taws xob tsim tawm los ntawm Underwriters Laboratories (USA).Tus txheej txheem cais cov yas raws li lawv hlawv nyob rau hauv ntau yam kev taw qhia thiab ib feem thicknesses los ntawm qis tshaj nplaim taws-retardant mus rau feem ntau nplaim-retardant nyob rau hauv 6 qhov sib txawv.
| Kev ntsuas UL 94 | Txhais kev ntsuas |
| V-2 | Kev kub hnyiab tsis pub dhau 30 vib nas this ntawm ib feem uas tso cai rau cov tee ntawm cov nplaim hluav taws xob ntsug. |
| V-1 | Kev kub hnyiab yuav tsum tsis pub dhau 30 vib nas this ntawm ib feem ntsug tso cai rau cov tee ntawm cov yas uas tsis yog mob. |
| V-0 | Kev kub hnyiab yuav tsum tsis pub dhau 10 vib nas this ntawm ib feem ntsug tso cai rau cov tee ntawm cov yas uas tsis yog mob. |
