Muaj ntau ntau yam ntawm cov hnab looj tes txiav, uas yog tswj los ntawm cov txheej txheem xeem. Feem ntau, kev lag luam tam sim no yog ib qhoTxiav-resistant-ntaubntawm European cov qauv rau kev tiv thaiv kev nyab xeeb ntawm kev lag luam hnab looj tes EN388, uas tau pom zoo los ntawm European Normative Institute (CEN) thaum Lub Xya Hli 2, 2003 raws li qhov tseeb version ntawm EN388: 2003. Cov qauv no muab cov qauv kev qhia tshwj xeeb, cov qauv kev sim, kos npe thiab phau ntawv qhia kev nyab xeeb kev tiv thaiv kev puas tsuaj ntawm cov hnab looj tes tiv thaiv kev ua haujlwm nyob rau hauv feem ntau ntawm cov hnab looj tes ua qauv EN420.Txiav-resistant-ntaub
Plaub lub hauv paus xeem yam ntxwv ntawm tus qauv no yog:
Hnav cov hnab looj tes raw khoom ua haujlwm tsis tu ncua kev sib txhuam coil tig;Txiav-resistant-ntaub
Tus naj npawb ntawm cov khoom siv raw ntawm cov hnab looj tes resistant yog resistant rau fiber ntau laser txiav khoom;
Resilience uas yog tsim kua muag qhib lub qhov nyob rau hauv lub hnab looj tes raw khoom yuav tsum tau npaum li cas cov nyiaj lub tuam txhab quab yuam;
Puncture kuj yog lub zog yuav tsum tau Pierce lub xib teg ntawm lub hnab looj tes nrog ib tug kho spike.
A. Kev sim hnav tsis kam: Plaub lub hnab looj tes raw khoom coj mus kuaj (6.45 cm²) yog rubbed nyob rau hauv A paub siab (9 kPa), thiab txhua tus qauv raug kuaj rau 100, 500, 2000 thiab 8000 lem raws li. Qib kev ua tau zoo yog txiav txim siab raws li tus naj npawb ntawm cov lem ntawm lub kauj tom qab plaub qhov kev xeem. Piv txwv li, yog tias cov khoom siv raw A raug kuaj, yog tias nws raug puas tsuaj tom qab rubbed 500 zaug, qhov hnav tsis kam ntawm cov khoom siv raw A yog qib 1, thiab lwm yam;
B. Txiav tsis kam xeem: ob qhov qauv tau sim nyob rau hauv lub zog ruaj khov ntawm 5 Copernicus specification, thiab qib tau tsim raws li tus naj npawb ntawm cov coil tig ua ntej txiav;
C. Kev sim siab: Plaub qhov qauv raug txiav los ntawm xib teg ntawm plaub lub hnab looj tes. Ob tug ntawm lawv tau sim nyob rau hauv cov kev taw qhia ntawm tus ntiv tes mus rau lub tes tsho, thiab lwm yam ob yog sim nyob rau hauv cov kev taw qhia ntawm xibtes dav kom raug ntsuas lub zog ntawm tearing qauv ntawm ib tug ceev ntawm 100 mm / min.
D. Puncture resistance test: Raws li arylon fiber 1414 npuag, plaub cov qauv txiav los ntawm xib teg ntawm plaub lub hnab looj tes tau siv los ntsuas qhov loj ntawm Copernican quab yuam ntawm cov ntsia hlau ntsia hlau tho cov qauv ntawm qhov ceev ntawm 100 mm / min.
Cov hnab looj tes txiav pov thawj feem ntau muab faib ua ob hom. Ib qho yog siv rau kev tiv thaiv kev nyab xeeb hauv kev tsim khoom, uas yog ntau dua hauv kev tsim khoom noj khoom haus engineering, biotechnology, hluav taws xob kev lag luam, kev lag luam khoom siv kev nyab xeeb, kev lag luam tsim cov iav toughened, thiab lwm yam. Lwm yam yog cov khoom siv tub ceev xwm hom hnab looj tes kev nyab xeeb, siv rau av qeeg thiab cawm, hluav taws cawm thiab lwm yam.
Cov hnab looj tes txiav pov thawj feem ntau yog siv los ua peb cov khoom siv raw
1, aramid fiber (Kevlar): aramid fiber yog lipid nplhaib acrylic emulsion cov khoom, hluavtaws fiber ntau xim yog lub teeb daj, muaj zog thiab lub teeb yuag, yooj, txheeb ze rau kev sib deev hauv qhov hnyav ntawm cov hlau 5 zaug muaj zog, nplaim hluav taws, tsis yooj yim rau yaj ntawm qhov kub thiab txias. Yog li ntawd, nws yog tsim nyog rau cov neeg ua hauj lwm teb, xws li: kev lag luam, industrial ntau lawm arc laser vuam, iav sib sib zog nqus ua thiab thiaj li nyob.
2, siab toughness polyethylene fiber ntau (Di Malegobi): fortitude, lub teeb yuag, zoo ua raws li, zoo hnav tsis kam, me me kev sib txhuam, siab hnav tsis kam, yog tib seem ntawm stainless hlau hlau ntau tshaj kaum zaug. Nws yog tsuas yog siv rau siab hnav-resistant ntau lawm thiab manufacturing teb neeg ua hauj lwm, xws li: optical fiber laser txiav ntau lawm thiab ua cov ntaub ntawv hlau, lub cev installation, kho vajtse pwm txheej txheem thiab thiaj li nyob.
3, stainless hlau xaim thiab polyester fiber ntaub ntaub tes knitting: stainless hlau hlau hnab looj tes muaj peev xwm loj los tiv thaiv kev txiav, haum rau kev daws cov riam ntug ntawm tib neeg kev tswj kev lag luam txheej txheem, ntxiv rau daim ntawv thov nyob rau hauv lub teb ntawm cov khoom noj thiab manufacturing, tab sis kuj siv rau kev tiv thaiv muaj peev xwm ntawm tsiaj tom.
Raws li tuaj yeem pom los ntawm cov khoom siv raw ntawm cov hnab looj tes txiav pov thawj, tsuas yog kev txiav ntug ntawm tib neeg cov txheej txheem kev tswj hwm kev lag luam raug daws, yog tias nws yog high-wear fiber laser txiav tsis tas yuav tsum tau.
Rau qhov kev ntsuam xyuas los tiv thaiv kev txiav, cov qauv raug coj mus rau hauv lub xib teg ntawm lub hnab looj tes, thiab cov fiber ntau laser raug txiav rov qab thiab tawm nrog ib tug rotating cutter ntawm tungsten steel khoom, thiab qhov ceev ratio yuav tsum tau txiav los ntawm cov qauv raug kaw los sib piv. cov txiaj ntsig ntawm cov qauv paj rwb ntaub qauv rau overlapping kev kuaj xyuas. Qhov siab dua qhov ntsuas ntsuas, qhov muaj zog tiv thaiv kev ua haujlwm tau zoo. Txawm li cas los xij, kev ntsuas kev txiav tsis kam tsis siv rau cov ntaub ntawv nyuaj heev.
High toughness polyethylene fiber txiav kom ua tiav 5 qib, aramid fiber ntau yog 4 txog 5 qib. Feem ntau, cov txiv neej ua fibers zoo dua li ntuj, tag nrho cov khoom tawv collodion zoo dua, cov khoom tawv tawv muaj zog dua li ntuj latex txaj.
