Lub Ntsiab Cai
Nyob rau xyoo tas los no, muaj kev txhawj xeeb ntau ntxiv txog kev pheej hmoo ntawm ib puag ncig thiab kev noj qab haus huv uas cov tshuaj halogen-based flame retardants siv rau hauv cov yas ua rau muaj. Yog li ntawd, cov tshuaj halogen flame retardants tau nrov vim lawv muaj kev nyab xeeb dua thiab ruaj khov dua.
Cov tshuaj tiv thaiv hluav taws uas tsis muaj halogen ua haujlwm los ntawm kev cuam tshuam cov txheej txheem combustion uas tshwm sim thaum cov yas raug hluav taws.
1. Lawv ua tiav qhov no los ntawm kev cuam tshuam lub cev thiab tshuaj lom neeg rau cov pa roj uas tso tawm thaum lub sijhawm hlawv. Ib qho ntawm cov txheej txheem feem ntau yog los ntawm kev tsim cov txheej txheem carbon tiv thaiv rau ntawm qhov chaw ntawm cov yas.
2. Thaum raug cua sov, cov tshuaj tua hluav taws uas tsis muaj halogen yuav ua rau muaj kev tshuaj lom neeg, uas tso dej lossis lwm yam pa roj uas tsis kub hnyiab. Cov pa roj no tsim ib qho thaiv ntawm cov yas thiab nplaim taws, yog li ua rau qeeb qeeb ntawm kev kis hluav taws.
3. Cov tshuaj tua hluav taws uas tsis muaj halogen yuav lwj thiab tsim ib txheej carbonized ruaj khov, hu ua char, uas ua haujlwm ua ib qho kev thaiv lub cev, tiv thaiv kev tso tawm cov pa roj uas yooj yim hlawv ntxiv.
4. Ntxiv mus, cov tshuaj tua hluav taws uas tsis muaj halogen tuaj yeem ua rau cov pa roj uas yooj yim hlawv tau yooj yim los ntawm kev ua kom cov free radicals thiab cov khoom uas yooj yim hlawv tau yooj yim. Cov tshuaj no ua rau cov tshuaj sib xyaw ua ke ntawm kev hlawv hluav taws ploj mus, ua rau qhov hluav taws kub tsawg dua.
Ammonium polyphosphate yog cov tshuaj tua hluav taws uas tsis muaj phosphorus-nitrogen halogen. Nws muaj kev ua haujlwm tua hluav taws zoo hauv cov yas uas tsis muaj tshuaj lom thiab tsis ua rau ib puag ncig puas tsuaj.
Daim Ntawv Thov Yas
Cov yas uas tiv taus hluav taws xws li FR PP, FR PE, FR PA, FR PET, FR PBT thiab lwm yam feem ntau siv rau hauv kev lag luam tsheb rau sab hauv tsheb, xws li dashboards, qhov rooj vaj huam sib luag, cov khoom rooj zaum, cov thawv hluav taws xob, cov tais cable, cov thawv hluav taws xob tiv taus hluav taws, cov switchgears, cov thawv hluav taws xob, thiab kev thauj dej, cov kav roj.
Tus qauv tiv taus hluav taws (UL94)
UL 94 yog tus qauv yas uas yooj yim kub hnyiab uas Underwriters Laboratories (Tebchaws USA) tso tawm. Tus qauv no faib cov yas raws li lawv hlawv li cas hauv ntau qhov kev taw qhia thiab qhov tuab ntawm cov khoom los ntawm qhov qis tshaj plaws uas tsis kub hnyiab mus rau feem ntau uas tsis kub hnyiab hauv rau qhov kev faib tawm sib txawv.
| Kev Ntsuas UL 94 | Kev Txhais ntawm Kev Ntsuam Xyuas |
| V-2 | Kev kub hnyiab yuav nres tsis pub dhau 30 vib nas this rau ntawm ib qho uas tso cai rau cov yas ntsug uas yooj yim hlawv tau poob. |
| V-1 | Kev kub hnyiab yuav nres tsis pub dhau 30 vib nas this ntawm ib feem ntsug uas tso cai rau cov tee yas uas tsis kub hnyiab. |
| V-0 | Kev kub hnyiab yuav nres tsis pub dhau 10 vib nas this ntawm ib feem ntsug uas tso cai rau cov tee yas uas tsis kub hnyiab. |
