LFT pwm yog dab tsi thiab qhov txawv ntawm SMC pwm yog dab tsi

1. Taw qhia rau LFT
LFT, ntev fiber ntau reinforced thermoplastic khoom, Lus Askiv yog Ntev Fiber reinforced Thermoplastics, yog piv nrog zoo tib yam fiber reinforced thermoplastic khoom, feem ntau, fiber ntev fiber reinforced thermoplastic khoom yog tsawg dua 1 hli, thaum LFT, qhov ntev ntawm cov fiber ntau yog feem ntau. ntau dua 2 mm. Cov cuab yeej ua haujlwm tam sim no tau khaws cov fiber ntau ntev hauv LFT saum 5 hli.
2. LFT muaj pes tsawg leeg
LFT (Long Glass Fiber Reinforced Plastic) tsom xam yog raws li micro-spectrum tsom xam thev naus laus zis, uas txheeb xyuas cov ntsiab lus ntawm txhua feem ntawm cov khoom siv profiled los ntawm micro-spectrum thiab kho cov qauv hauv paus. Ntev fiber ntau cov ntaub ntawv thermoplastic yog muab piv nrog cov khoom siv fiber ntau siv cov thermoplastic zoo tib yam. Feem ntau siv cov matrix cob yog PP, ua raws li PA, thiab qee cov resins xws li PBT, PPS, thiab SAN kuj siv. LFT muaj ntau daim ntawv thov hauv tsheb, thiab lub ntsiab kom zoo dua yog qhov yooj yim ntawm cov ntaub ntawv tuaj yeem sib xyaw.
Peb, qhov sib txawv ntawm LFT thiab SMC
Cov khoom tsim cov txheej txheem ntawm LFT daim ntawv yog zoo ib yam li SMC (Sheet Molding) nyob rau hauv thermosetting composite iav fiber reinforced yas. Nws kuj yog tsim los ntawm nias cov ntawv hauv pwm. LFT yog ib daim ntawv nyuaj uas yog cua sov thiab muag muag thiab tom qab ntawd txias-nias rau hauv pwm, thaum SMC yog kub-nias tom qab cov ntawv txias mos muab tso rau hauv pwm.
Piv nrog SMC daim ntawv, kev ua haujlwm ntawm LFT daim ntawv muaj qhov zoo hauv qab no:
1. Tsis muaj teeb meem thiab saj tsis zoo, tuaj yeem txhim kho qhov chaw ua haujlwm.
2. Lub teeb yuag, qhov ceev tsuas yog 1 ~ 1.2g / cm3.
3. Cov khoom khib nyiab thiab cov khoom pov tseg tuaj yeem rov ua dua kom txo cov khoom pov tseg.
4. Lub zog siab dua SMC, thiab qhov cuam tshuam toughness yog qhov tshwj xeeb tshaj plaws.
5. Kev tiv thaiv corrosion thiab kev ua tau zoo ntawm hluav taws xob.
6. Cov khoom nias ceev yog ob peb zaug sai dua SMC, thiab cov khoom siv tau zoo heev.
