Qhov kev thov rau kev txuam cov thermoplastic hauv txua hluav taws xob ntau yog kwv yees li 500,000 tons, thiab kev txhim kho txhua xyoo yog ob zaug ntawm cov teb chaws txawv. Hauv xyoo 2001, cov thev naus laus zis hauv cov thermoplastic hauv lub teb chaw tsuas yog 5 feem pua ntawm lub ntiaj teb kev ua lag luam. Txawm li cas los, 2013 Nyob rau hauv lub xyoo, daim duab tau nce mus rau 20%. Tam sim no, 80% ntawm cov khoom siv hluav taws xob ntev hauv tha xim thermoplastic yog los ntawm kev ua lag luam lossis kev sib koom ua ke.
Automotive sector yog qhov chaw siv daim ntawv loj tshaj plaws rau cov tshuab fais fab ntev coj los siv thermoplastic composites. Kwv yees li ntawm 70% ntawm LFT cov khoom siv hauv kev lag luam automotive kom loj automotive cheebtsam. Cov piv txwv yog:
(1) Pem hauv ntej
Lub qhov kawg ntawm sab kawg nkaus yog txhaj tshuaj molded nrog 30% ntev iav polypropylene, uas ua ke rau hauv pem hauv ntej qhov ntawm lub tshuab radiator, horn, condenser, bracket thiab lwm yam pem hauv ntej qhov hauv ib qho, uas txo cov nqi ntau lawm thiab txo qhov nyhav ntawm qhov chaw ntawm lub GMT Txog 30%.
(2) rooj tog vaj huam sib luag
Raws li cov ntaub ntawv pov thawj rau cov qauv kho tsheb, daim ntawv thov cov iav ntev fiber reinforced polypropylene hauv tsheb automated pem hauv ntej rooj modules tau raug xaiv los ntawm Ford, Mazda thiab lwm cov tuam txhab. Lub rooj nruab nrab ua ke muaj ntau yam kev ua haujlwm xws li rooj xauv qhov rooj, cov rooj nqa qhov rooj, cov lus sib tham, thiab kev tiv thaiv tubsab. Cov cuab yeej ua los ntawm 30% ntev iav fiber reinforced polypropylene khoom. Nyob rau hauv tus txheej txheem ntawm tsim qhov rooj module, cov kws txawj thiab cov kws tshawb nrhiav tau tshawb fawb txog cov khoom ntawm ntev iav fiber ntau zog siv tshuaj polypropylene rau kev txhaj tshuaj molding, tshwj xeeb tshaj yog cov cwj pwm tsis kam ntawm cov khoom. Cov kev tshwm sim qhia tau tias ntev lub khob fiber ntau reinforced polypropylene Cov khoom tsis tsim cov tseem ceeb txawm tias thaum raug siab kub ntawm 100 ° C thiab tau zoo dua tsis txaus siab dua li luv iav reinforced polypropylene.
(3) Lub nra thiab lub tsheb ntiag tug
40% ntev iav fiber reinforced polypropylene tshuaj molded cov khoom muaj zoo feem cuam toughness thiab siab zog, thiab tseem muaj qhov zoo ntawm lub teeb nyhav thiab luv nqi.
(4) Lub rooj tsheb roj teeb
Ntev iav fiber reinforced polypropylene injection molded cov khoom muaj cov nplua nuj ua tsis taus thiab qis qis. Vim lub siab muaj zog thiab toughness ntawm ntev iav fiber reinforced polypropylene, lub plhaub phab ntsa yuav ua tau nyias, yog li txo lub luj thiab ua tau yooj yim tsau.
Tam sim no, feem ntau ntawm cov roj teeb rooj plaub raug tsim los ntawm ABS pob zeb. Cov roj teeb rooj tsim los ntawm cov iav ntev fiber reinforced polypropylene puas khoom tsis tsuas yog qis hauv nqe dua ABS ABS, tab sis kuj superior hauv kev kawm rau ABS ABS.
(5) Lub taub hau cua thiab lub hau taub hau ntawm lub raj cua
LFTP cov ntaub ntawv moulded cov ntaub ntawv tuaj yeem siv los hloov lub kiv cua thiab lub cev lim lub hau ntawm lub cev muaj zog thawv. Vim yog qhov kub loj ntawm cov cuab yeej no, cov ntaub ntawv SFRTP thiab cov ntaub ntawv ntshiab yuav ua tsis tau raws li qhov xav tau ntawm kev siv.
(6) Coaxial lub tog raj kheej clutch ntu qhov chaw rau tsheb thauj khoom
Ntev iav fiber reinforced nylon composite txhaj tshuaj molded cov khoom nrog ib khob fiber ntau cov ntsiab lus ntawm 50% muaj peev xwm hloov txhuas castings. Ntev iav / ntaub hnyav muaj ib tus nplaim dej uas tswj qhov chaw loj kom pom txoj kev sib hloov ntawm lub elastomeric bushing raws lub hauv paus loj.
Hauv cov ntsiab lus, LFT cov ntaub ntawv muaj cov nqi qis, thaum cov khoom siv dag zog xws li kev nruj qaum, lub zog thiab kev muaj zog, thiab kev kub cev tsis haum yog qhov zoo. Nws lub ntsiab lus qhia yog: cov yam ntxwv ntawm cov yam ntxwv uas yuav tsum tau ua ntawm cov khoom siv dag zog thiab qhov chaw dimension. Hauv qee yam, nws tuaj yeem hloov kim kim engineering. Tsis tas li ntawd, nws kuj siv tau los ua cov khoom pab rau kev txhim kho lub zog thiab kev muaj zog ntawm polypropylene cob. .
