Dab tsi yog fiber reinforced thermoplastic?
Thermoplastics yog ib lub plastics ntau plag thiab yog formulated nrog plastics raws li lub ntsiab feem ntawm ib thermoplastic cob thiab nrog ntau yam additives. Thermoplastic yas cob txuas cov hlua los yog cov ceg ntoo, tsis muaj chemical bonds ntawm cov khoom siv chiv fab, nyob rau hauv tej qhov chaw sov, tuaj yeem muag lossis yaj ua kom zoo, zoo ib yam tom qab txias; lub xeev no yuav rov qab ua dua thiab ib txwm muaj cov khoom zoo, thiab qhov no rov qab yog qhov hloov ntawm lub cev.
Cov thermoplastics feem ntau yog cov hauv qab no:
Polyethylene (PE)
Polypropylene (PP)
Polyvinyl chloride (PVC)
Polystyrene (PS)
Polyoxymethylene (POM)
Polycarbonate (PC)
Polyamide (PA)
Acrylic yas
Lwm cov polyolefins thiab lawv cov copolymers
Polysulfone
Polyphenylene ether
Chlorinated polyether
Los ntawm kev hloov kho ntawm plastics thiab sib ntxiv ntawm fibrous tshuaj nyob rau hauv plastics, cov nram qab no cov khoom ntawm cov plastics plab txawv tau zoo heev tuaj:
1. Txhim kho kom muaj zog, xws li tensile, bending, compression, elastic modulus thiab creep tsis kam;
2, nce lub tshav kub distortion kub;
3, txo qhov linear expansion coefficient;
4, txo kev yoojyim dej, ua rau kom muaj kev ruaj ntseg;
5, ua rau kom muaj zog;
6, inhibit kev ntxhov siab tawg.
Ntau cov thermoplastics muaj qhov sib txawv txav ntawm qhov sib txawv, uas cov tseem ceeb tshaj plaws thiab feem ntau yog siv cov polyamides, thiab polyvinyl chloride, polycarbonate, ABS, polyethylene, polypropylene thiab lwm yam teebmeem kev ua tau zoo heev.
Reinforcing fiber ntau cov khoom
Cov khoom siv thermoplastic yuav tsum muaj qhov muaj zog, tsis tshua muaj elongation, zoo rigidity, me ntsis creep, zoo heev kub thiab lwm yam ntxwv, xws li: iav fiber, carbon fiber, basalt fiber, aramid fiber ntau dua.
Ntawm lawv, khob fiber ntau yog cov feem ntau siv thiab muaj cov nqi ntau tshaj plaws, vim hais tias iav fiber tsis tsuas tau raws li cov lus saum toj no, tab sis kuj yog tsim rau industrial ntau nrog tsawg nqi thiab qhov chaw dav. Nws yog qhov tseem ceeb ntawm raw cov khoom siv hluav taws xob (reinforced thermoplastics (FRTP).
