Tus Qauv Tshiab Uas Tiv Thaiv Hluav Taws Rau Cov Khoom Uas Tsis Yog Hlau

Yuav tsum muaj Lub Tebchaws Tus Qauv rau Tsheb Kauj Vab Fais Fab "Kev Nyab Xeeb Kev Cai rau Tsheb Kauj Vab Fais Fab" (GB 17761-2024), qhov kho dua tshiab tau raug tso tawm thiab siv txij li lub Cuaj Hlis 1, 2025, hloov tus qauv yav dhau los (GB17761-2018).

Tus qauv tshiab rau "Cov Lus Qhia Txog Kev Nyab Xeeb ntawm Tsheb Kauj Vab Hluav Taws Xob" (GB 17761-2024) tso cai rau cov kev cai nruj dua rau kev ua haujlwm ntawm cov khoom siv tsis yog hlau hauv lub cev tsheb.Ntxiv rau cov voj voog hluav taws xob thiab cov khoom siv hluav taws xob txuas nrog uas yuav tsum tau ua raws li UL94 V-0 raws li xyoo 2018, tus qauv tshiab kuj qhia meej tias lub thawv roj teeb yuav tsum ua tiav qib UL94 V-0, thaum cov ntaub mos mos, cov ntaub, tawv, cov xov hluav taws xob, thiab cov qauv nyias nyias uas yooj yim khoov tau yuav tsum ua tau raws li qib hluav taws kub siab dua. Qhov kev hloov pauv no lub hom phiaj yog txhim kho kev nyab xeeb ntawm cov tsheb kauj vab hluav taws xob hauv cov xwm txheej hnyav xws li hluav taws.

Tus Txheej Txheem Tshiab rau Cov Khoom Siv Uas Tsis Yog Hlau / Cov kev cai tshwj xeeb rau kev tiv taus hluav taws thiab kev tiv taus hluav taws yog dab tsi?

6.4.1 Cov kev cai tiv thaiv hluav taws thiab nplaim taws

Cov ntaub ntawv tsis yog hlau siv rau hauv tsheb kauj vab hluav taws xob ua tau raws li cov kev cai hauv qab no rau kev tiv thaiv hluav taws thiab hluav taws kub.

• a) Kev ua haujlwm ntawm cov khoom siv tsis yog hlau uas muaj nyob rau hauv txhua lub voj voog hluav taws xob thiab lawv cov khoom siv hluav taws xob txuas nrog (xws li cov voj voog them, cov hloov hluav taws xob, cov khoom siv tiv thaiv luv luv, cov khoom siv hluav taws xob, cov khoom siv sib txuas, thiab lwm yam, tshwj tsis yog cov xov hlau) yuav tsum ua raws li qib V-0 hauv GB / T5169.16.
• b) Cov ntaub ntawv siv rau hauv ncoo uas ywj pheej (xws li cov ntaub ntawv ua npuas ncauj uas tau ntim rau hauv lub rooj zaum) yuav tsum ua tau raws li cov yam ntxwv ntawm kev sib xyaw ua ke ntawm Rooj 2 ntawm GB38262-2019 rau cov ntaub ntawv siv rau hauv ncoo uas ywj pheej.
• c) Lub sijhawm hluav taws xob ntawm cov ntaub ntawv tsis yog hlau (xws li lub rooj zaum npog) yuav tsum yog ≤15s, lub sijhawm kub hnyiab yuav tsum yog ≤30s, qhov ntev ntawm kev puas tsuaj yuav tsum yog ≤200mm, thiab cov pa oxygen yuav tsum yog ≥26.0%.
• d) Cov tawv nqaij uas tsis yog hlau (xws li tawv npog lub rooj zaum, thiab lwm yam) yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm cov yam ntxwv combustion ntawm cov ntaub ntawv tawv (rau cov rooj zaum) hauv Rooj 2 ntawm GB382622019.
• e) Qib kev ua haujlwm ntawm cov khoom siv uas tsis yog hlau (xws li cov chaw roj teeb) uas sib cuag ncaj qha nrog lub roj teeb yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm V-0 qib hauv GB / T5169.16.
• f) Txhua lub xov hluav taws xob yuav tsum muaj qhov nplaim taws ntsug ntawm ≤425 hli.
• g) Kev ua haujlwm ntawm lwm cov khoom siv uas tsis yog hlau (xws li cov khoom dai kom zoo nkauj, cov khoom tiv thaiv av nkos, thiab lwm yam, tab sis tsis suav nrog cov log tsheb) yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm V-1 qib hauv GB/T5169.16. Rau cov qauv nyias uas yooj yim khoov thiab cov qauv uas nkhaus tab sis tsis kub hnyiab thaum raug hluav taws, lawv cov kev ua haujlwm ntawm kev ua haujlwm yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm VTM-1 qib hauv GB/T40302.

Sichuan Taifeng ua tus kws tshaj lij kev xa khoom tshwj xeeb hauv R & D, kev tsim khoom, thiab kev muag khoom ntawm cov nplaim taws retardants, peb muaj ntau yam khoom sib txawv ntawm ammonium polyphosphate (APP)

TF-201: nyiam cov txheej txheem tiv thaiv hluav taws

TF-211/TF-212: nyiam siv rau cov txheej txheem textile

TF303/TF-303S: yaj tau hauv dej, nyiam siv rau kev tsau thiab kho cov ntoo, fiberboard, ntawv, textiles, xyoob fibers, thiab lwm yam.

TF-241: nyiam siv polyolefin (xws li PP, PE, PBS) thiab roj hmab.

Taifeng cov khoom siv hluav taws kub Ammonium Polyphosphate uas tsis yog halogen tau npaj txhij lawm, txais tos hu rau peb.
