Manufacturing yam ntxwv ntawm aramid fiber

Manufacturing yam ntxwv ntawm aramid fiber

Rau kev tsim ntawm Kevlar threads nrog cov khoom siv, yas yog tsim, uas yog raug rau kub kub, nyob rau hauv tus ntawm cov muaj pes tsawg leeg tau ib tug nplaum zoo nkauj. Nws dhau los ntawm lub spinneret, los ntawm qhov ntev, muaj zog fibers loj hlob tawm ntawm lub orifices. Lawv raug mob ntawm lub nruas thiab tom qab ntawd txiav mus rau hauv cov ntsiab lus ntev los ntawm cov ntaub tawv tawv.

Tus tswv ntawm patent tsim 29 thiab 49 Kevlar kev hloov kho, nrog rau lwm hom ntaub ua kom xaj. Qhov no yog vim lawv tsis tau txais koob meej vim tias lawv yog qhov tshwj xeeb thiab siv tau rau kev ua haujlwm nqaim.

Hauv kev tsim cov Kevlar fibers, ob qho tib si thev naus laus zis thiab cov khoom tiav ua tau raws li qee qhov yuav tsum tau ua. Txhawm rau kom ntseeg tau tias nws ua tau raws li txhua tus yam ntxwv, ntawm txhua theem ntawm kev tsim khoom, cov kev txwv hauv qab no raug tswj hwm:

noo noo; hnav khaub ncaws
Network ceev, ntsuas raws li linear metrics.
Modulus ntawm elasticity, kwv yees nyob rau hauv nro:.
Twist; 0
saggy xov
Tom qab kev tsim khoom tiav, lub zog tensile raug soj ntsuam. Tsis tas li ntawd, elongation qhov tseem ceeb ntawm fiber ntau breakage tau txiav txim siab
