Para-aramid webbing yog qhov ua tau zoo webbing woven nrog para-aramid filaments. Kel var yog cov khoom lag luam lub npe ntawm aramid fiber ntau cov khoom tsim los ntawm DuPont. Lub npe qub ntawm cov khoom siv yog" polyterephthalamide" ;. P-phenylenediamine", chav ntsuas ntawm cov txheej txheem tshuaj yog - [- CO-C6H4-CONH-C6H4-NH -] - Cov pawg amide txuas nrog lub nplhaib benzene yog para-position qauv, tseem hu ua para-aramid Cov. Aromatic poly Lub vev xaib tseem muaj kev tiv thaiv kev kub zoo, tsis tsuas yog siv tau txuas ntxiv mus rau qhov ntsuas kub ntawm 196 ° C rau 4204 ° C, tab sis tsis muaj qhov hloov pauv lossis poob, thiab nws muaj insolubility thiab hluav taws kub tsis kam (tiv) , thiab tsuas yog pib ua carbonization Qhov kub siab tshaj plaws yog 427 degrees, thiab yuav tsis muaj brittleness thiab kev ua tau zoo txawm tias qhov ntsuas kub tsawg ntawm 196 degrees. Nws tuaj yeem tiv taus kub mus txog 538 degrees rau lub sijhawm sib tiv tauj luv thiab muaj kev tiv thaiv zoo kub thiab hnav tsis kam. .. Para-aramid webbing yog hom tshiab ntawm cov khoom siv sib xyaw. Cov khoom muaj ob qho kev ua haujlwm siab thiab lub teeb hnyav. Hauv tib lub cev nyhav, nws lub zog yog 5 zaug ntawm cov hlau xaim thiab 2.5 npaug ntawm cov hlau xaim. f E chav kawm iav fiber ntau, lub zog yog 10 npaug piv ntawm txhuas. Para-aramid webbing yog siv dav hauv: kev qhia txog kev nyab xeeb ntawm kev nyab xeeb, siv khaub ncaws, kev siv tsheb thauj khoom, kev tiv thaiv kev tiv thaiv kev ruaj ntseg, cov menyuam siv, kev siv sab nraub qaum, kev siv txoj siv sia, cov khoom ua si sab nraum zoov, thiab lwm yam. Nws cov qauv tuaj yeem muab faib ua tiaj, herringbone, twill, weave dawb, jacquard, satin, tav, thiab lwm yam.
Para-aramid webbing muaj cov yam ntxwv li nram no:
1. Lub teeb ceeb thawj
2. Lub zog muaj zog
3. Cov qauv siab
4. Dimensionally ruaj khov
5. Tsawg shrinkage
6. puncture kuj
7. Hnav tsis kam
8. Kub tsis kam
9. Tshuaj lom neeg tsis kam
10. Nplaim taws rov qab
11. Cov cuab yeej zoo siv
12. Cov txiaj ntsig zoo, xws li cov khoom zoo dielectric.
Weaver yog kev coj ua lub webbing khoom lag luam nyob hauv Suav teb, mob siab rau kev tsim cov webbing tshwj xeeb, xws li aramid webbing, UHMWPE webbing, nylon webbing, thiab polyester webbing. Los ntawm cov khoom lag luam txhim kho, kev tsim khoom, kev muag khoom mus rau cov neeg ua haujlwm kev cob qhia, kev tswj hwm thiab kev tswj hwm, peb tau txais kev ntseeg siab thiab kev lees paub ntawm ntau tus neeg muas zaub tshiab thiab qub. Cov khoom lag luam no tau siv dav hauv cov khaub ncaws, cov tsiaj, cov khoom lag luam sab nraum zoov, kev nyab xeeb hluav taws, kev nyab xeeb rau kev lag luam, khoom siv kho mob, kev siv tub rog thiab kev lag luam thiab ntau lwm cov teb. Yog tias koj muaj cov kev xav tau sib raug zoo, thov hu rau peb, peb tuaj yeem muab cov kev pabcuam rau koj.
