Ntev iav Fiber ntau PBT yas Raw Khoom

Pyrolysis thiab hluav taws cwj pwm ntawm cov iav-fiber reinforced poly (butylene terephthalate) (PBT / GF) nrog ob hom hlau phosphinates li nplaim retardants nrog thiab tsis melamine cyanurate (MC) tau soj ntsuam los ntawm kev thevogravimetry, thermogravimetry coupled nrog infrared spectroscopy , flammability, thiab cov khoom xyaw calorimeter zoo li scanning electron microscopy / energy dispersive X-hluav taws xob spectroscopy thiab X-ray fluorescence spectroscopy. Hauv PBT / GF, ntau npaum li 13-20% ntawm cov nplaim halogen dawb tsis muaj hluav taws xob phosphinate lossis txhuas phosphinate ua ke nrog MC ua raws li cov qauv siv hluav taws xob thiab kev siv hluav taws xob (UL 94 = V-0; LOI> 42%), whereas kev siv cov zinc phosphinate los sis zinc phosphinate tib yam nrog MC tsis zoo rau kev coj tus cwj pwm zoo txaus siab (UL 94 = HB; LOI = 27-28%). Qhov kev kawm nyob rau hauv yuam kev flaming tej yam mob (cone calorimeter) yog zoo heev rau ob qho tib si ntawm cov hlau phosphinates. Kev siv cov txhuas thiab zinc ntsev ua rau cov nplaim hluav taws xob zoo li feem ntau vim qhov kev tso tawm ntawm phosphinate compounds hauv cov roj theem. Ob hom hlau phosphinates thiab MC ua ke nrog cov polymer hloov cov yam ntxwv ntawm kev hloov. Txawm li cas los xij, ib feem ntawm cov zinc phosphinate vaporizes ua ib qho tiav phom. Vim yog cov cwj pwm txawv ntawm tus cwj pwm ntawm cov hlau, tsuas yog cov txhuas phosphinate ua rau me me ntawm carbon carbonaceous carbon thermal. Hauv particular, cov txhuas phosphinate-terephthalate tsim tau ruaj khov dua cov zinc phosphinate-terephthalate. Tus nqi tsawg tsawg ntawm char nws muaj cov nyhuv tseem ceeb heev rau lub thermal cov khoom thiab kev ruaj khov kho ntawm qhov seem thiab yog li qhov kub ntxhov.

Xiamen LFT Composite Plastic Co., ltd yog tsuas ua ntev fiber ntau zog thermoplastic khoom lag luam, peb pab pawg muaj 20 kev txawj ntse, cog lus rau cov txuj ci ntev coj los siv tshiab daim ntawv thov thiab kev lag luam, tshwj xeeb tshaj yog qhov kev xav tau ntawm kev kawm siab los yog ntev carbon fiber reinforced polymer cov ntaub ntawv 'cov no yog cov hais txog filaments, thiab siv lawv kom ua tau raws li koj cov kev xav tau
