Kev tsim tawm ntawm UHMWPE Fiber

UHMWPE fiber ntau yog cov khoom siv tshiab, nws daim ntawv thov teb yog dav heev, los ntawm aerospace mus rau lub teb chaws tiv thaiv tub rog, thiab tom qab ntawd mus rau pej xeem txoj hlua mesh, muaj nws cov kev lag luam dav dav thiab kev loj hlob. Txawm li cas los xij, vim yog cov yam ntxwv ntawm cov fiber ntau no thiab cov yam ntxwv ntawm qhov hnyav molecular ultra-siab, nws txawv heev ntawm kev tsim cov tshuaj fiber ntau. Tag nrho cov overstretch ntawm cov pa tshuaj fiber ntau [staple fiber] feem ntau yog: ob peb zaug -20 zaug yuav ua tau, thiab tag nrho cov overstretch ntawm no gel fiber ntau tshaj 100 zaug, yog vim li cas koj xav stretch ntau zaus? Qhov no yog vim muaj cov kuab tshuaj, thiaj li hais tias tus naj npawb ntawm cov saw entanglements nyob rau hauv lub fiber yog txo. Hauv lwm lo lus, hom fiber ntau no, nws yuav siv sijhawm ntev los ntawm spinning spinneret mus rau cov khoom molding kom ua tiav, cov txheej txheem ntev, muaj ntau qhov sib txuas, thiab kev tswj yog ib txwm nyuaj. Nws zoo li cov saw hlau, txawm tias qhov txuas twg ploj lawm, tag nrho cov saw yuav tawg.
Nyob rau hauv txhua tus txheej txheem ntawm kev tsim khoom, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj cov txheej txheem sab nraud ntawm cov fiber ntau, tab sis kuj yuav tsum paub thiab nkag siab txog cov kev hloov pauv hauv cov qauv molecular ntawm cov fiber ntau, kom pom tias cov kev hloov hauv nws cov qauv sab hauv raws li cov txheej txheem. tias nws tuaj yeem ua tiav hauv ntu no. Hauv lwm lo lus: nyob rau hauv txhua txoj kev tsim cov fiber ntau, nws cov kev ntsuas sab hauv thiab sab nraud hloov pauv tsis yog lub xeev uas tib neeg xav ua tiav. Yog li ntawd, nyob rau hauv cov txheej txheem ntau lawm, kev tshuaj xyuas lub cev thiab kev ntsuam xyuas ntawm cov khoom semi-tiav yog indispensable txhais tau tias ntawm intermediate tswj.
Nws tsis yog yooj yim los tsim cov khoom tsim nyog thiab ua tiav ib qho kev tsim khoom. Tam sim no, lub degree ntawm theoretical cognition nyob rau hauv daim teb no yuav tsum tau kawm ntxiv thiab txhim kho, tshwj xeeb tshaj yog cov paub tab loj-scale industrialization ntau lawm technology yog tsis mature heev. Qhov xwm txheej yog txawv, kev tsom xam dav dav: muaj teeb meem kev lag luam, muaj teeb meem ntawm cov cuab yeej siv, thiab qee txoj kev tswj hwm. Tau kawg, cov neeg ua haujlwm thiab cov teeb meem nyiaj txiag tsis tuaj yeem txiav tawm.
Kev tsim cov UHMWPE fiber ntau yog high-tech, thiab kev tswj ntawm txhua qhov txuas hauv cov txheej txheem tsim khoom yog nruj heev thiab kev tswj xyuas qhov tseeb yog siab heev. Hauv qee ntu, qhov sib txawv ntawm qhov kub thiab txias yog 1 degree, thiab qhov sib txawv ntawm qhov sib txawv yog 0.1 m / min, uas yuav ua rau cov plaub hau ntau thiab cov taub hau tawg, uas ua rau muaj qhov tshwm sim ntawm winding rolls, thiab zus tau tej cov pa chemical fibers tsis tas yuav nruj heev.
