Tam sim no, plaub lub tuam txhab thoob ntiaj teb tau paub txog kev lag luam kev lag luam ntawm para-aramid 1414. Ntawm lawv, dupont muaj cov chaw lag luam hauv cov koomhaum koom siab, cov koomhaum koom siab, thiab Nyijpooj, nrog kev tsim khoom txhua xyoo muaj peev xwm kwv yees li 33,000 tons. Nyiv teijin muaj factories hauv Nyiv thiab netherlands. Tag nrho muaj kwv yees li 24,500 tons; sab qab teb korea lub tuam txhab cologne muaj tsuas yog lub Hoobkas nyob hauv lub tebchaws, nrog kev ua txhua xyoo ntau lawm txog kwv yees li 1,000 tons. Lavxias cov khoom lag luam thiab cov txheej txheem sib txawv kiag li dupont thiab teijin, muaj peev xwm ntau txog 1,000 tons hauv ib xyoos. Para-aramid 1414 yog siv dav hauv cov ntawv sau npe tub rog.
Para-aramid 1414, nws lub npe tshuaj yog poly terephthaloyl-p-phenylenediamine fiber. Dupont lub tuam txhab ntawm cov koom ua ke yog hu ua kevlar. Nws yog thawj cov fiber ntau ua haujlwm zoo uas muaj txiaj ntsig thiab tseem nyob hauv cov khoom lag luam loj thiab siv.
Para-aramid 1414 muaj lub zog ua haujlwm ntau dua 28 g / denier, uas yog 5 txog 6 npaug ntawm cov hlau zoo. Lub siab txheej txheem yog 2 txog 3 zaug ntawm cov hlau lossis fiberglass. Cov tawv tawv yog ob zaug ntawm cov hlau, thiab qhov hnyav tsuas yog hlau. 1/5. Para-aramid 1414 muaj qhov kub ntau yam rau kev siv txuas ntxiv thiab yog qhov ruaj khov rau lub sijhawm ntev -196 ° c mus txog 204 ° c. Kev txo lub zog ntawm 150 ° c yog 0, tsis decompose thiab yaj ntawm qhov kub ntawm 560 ° c, kev tiv thaiv tshav kub zoo dua li cov meta-aramid 1313, thiab muaj cov rwb thaiv tsev zoo thiab tiv thaiv corrosion, thiab muaj lub neej ntev , yog li yeej "Lub koob npe ntawm hluavtaws steel hlau.
Nws muaj lub zog tensile zoo tshaj plaws thiab zoo heev kub tsis kam thiab toughness, thiab nws kuj muaj zoo alkali tsis kam, organic solvent tsis kam thiab tshuaj dawb tsis kam lees zoo li tiv taus kab thiab mildew. Qhov twg siab zog, tensile lub zog, kua muag tsis kam, puncture tsis kam thiab siab kub kuj yuav tsum tau, para-aramid 1414 yog ib daim teb ntawm cov txuj ci zoo thiab muaj irreplaceable superiority.
