ntchito kuluka kukongola zovala mbali monga ntchito spandex nsalu nsalu

zinchito kuluka kukongola zovala mbali monga ntchito spandex nsalu nsalu, ntchito yake wakhalanso pang'onopang'ono anayamba thupi pulasitiki, kupyolera kuti embed spandex kuluka nsalu, akhoza kupanga pulasitiki thupi mtundu wa zovala zoluka, ndipo akhoza kunyamula matako, mimba kwenikweni. , ndipo pamsika wamakono wa zovala umakhala ndi gawo lalikulu la malonda.Panthawi imodzimodziyo, spandex imakhala ndi chitetezo cha thrombus, chomwe chimapangitsanso masokosi opangidwa ndi spandex otchuka.Ndi kudzera mu kusintha kwa spandex, mphamvu yopondereza yotanuka imawonjezeka pang'onopang'ono kuchokera kumapeto kwa masokosi oluka mpaka kumapeto kwapansi, kuti apititse patsogolo kuyenda kwa magazi, kuti akwaniritse ntchito yoletsa thrombus.
Kusiyana pakati pa European standard EN388 ndi American standard ANSI/ISEA105
Mumiyezo iwiri iyi, kufotokozera kwa mulingo wa kukana odulidwa kumasiyana.

Magolovesi osamva odulidwa omwe amatsimikiziridwa ndi muyezo waku Europe adzakhala ndi chithunzi cha chishango chokhala ndi mawu akuti "EN 388" pamenepo.Pali manambala 4 kapena 6 ndi zilembo pansi pa chithunzi cha chishango.Ngati ndi manambala 6 ndi zilembo, zikutanthauza kuti muyezo waposachedwa wa EN 388:2016 ukugwiritsidwa ntchito.Ngati ndi manambala 4, zikutanthauza kuti ndi muyeso wakale wa 2003.

↑ Chithunzi chakumanzere ndi muyezo wakale, ndipo chithunzi chakumanja ndi chatsopano.
Manambala 4 oyambirira ali ndi matanthauzo ofanana, omwe ndi "wear resistance", "cut resistance", "tear resistance", ndi "puncture resistance".Chiwerengero chokulirapo, chimagwira ntchito bwino.Kalata yachisanu imatanthawuzanso "kukana kudulidwa", koma njira yoyesera ndi yosiyana ndi yachiwerengero chachiwiri, ndipo chiwonetsero cha kalasi ya kukana odulidwa chimakhalanso chosiyana, chomwe chidzakambidwe mwatsatanetsatane pambuyo pake.Kalata yachisanu ndi chimodzi imayimira "kukana kukhudzidwa" ndipo imayimiridwanso ndi zilembo.Komabe, padzakhala nambala yachisanu ndi chimodzi pokhapokha ngati kuyesa kwa mphamvu kumachitidwa.Ngati sizichitika, padzakhala manambala 5 okha.Ngakhale mtundu wa 2016 wa muyezo waku Europe wakhala ukugwiritsidwa ntchito kwazaka zopitilira 4, pali mitundu yambiri yakale ya magolovu pamsika.Magolovesi odulidwa omwe amatsimikiziridwa ndi miyezo yatsopano ndi akale onse ndi magolovesi oyenerera, koma ndi bwino kugula magolovesi odulidwa omwe amagwiritsa ntchito manambala a 6 ndi zilembo kuti asonyeze ntchito ya magolovesi.American muyezo ANSI 105 mawu.

Mu 2016, American standard ANSI 105 idasinthidwanso.Mulingo wokana wodulidwa woyambirira udayimiridwa ndi 1-5 pazithunzi za chishango, ndipo tsopano ukuimiridwa ndi "A1" mpaka "A9".Mofananamo, chiwerengero chachikulu, ndipamwamba mlingo wa kukana odulidwa.

Koma bwanji kusintha njira yamagulu kuchokera pamilingo 5 mpaka 9?Chifukwa chake ndi chakuti pakutuluka kwa zida zatsopano zambiri, mwatsatanetsatane mwatsatanetsatane amafunikira kuwonetsa kukana kodulidwa kwa magolovesi.Munjira yatsopano yopangira ma grading, A1-A3 kwenikweni ndi yofanana ndi 1-3 yoyambirira, koma poyerekeza ndi 4-5 yoyambirira, A4-A9 imagwiritsa ntchito magiredi 6 kugawa mitundu yoyambirira ya giredi 2, yomwe imatha kugonjetsedwa ndi magolovesi.Dulani kugonana kuti muwoneke bwino.Muyeso wa ANSI, kusinthidwa sikungowonetseratu msinkhu, komanso njira yoyesera.Mayeso oyambilira adagwiritsa ntchito muyezo wa ASTM F1790-05, womwe umalola kuyesa pamakina a TDM-100 (njira yoyesera imatchedwa TDM TEST) kapena makina a CPPT (njira yoyesera imatchedwa COUP TEST), tsopano muyezo wa ASTM F2992-15 ukugwiritsidwa ntchito, TDM yokha ndiyomwe imagwira ntchito. analola TEST kuyesa.Kodi pali kusiyana kotani pakati pa TDM TEST ndi COUP TEST?

COUP TEST imagwiritsa ntchito tsamba lozungulira ndi kukakamiza kwa Newtons 5 kuti igubuduze ndikudula pamagetsi, pomwe TDM TEST imagwiritsa ntchito tsamba kuti ikanize zida zamagetsi ndi zovuta zosiyanasiyana, kudula mmbuyo ndi mtsogolo mopingasa pa liwiro la 2.5 mm / s. .Ngakhale muyezo watsopano wa ku Europe wa EN 388 umanena kuti njira ziwiri zoyesera, COUP TEST ndi TDM TEST, zitha kugwiritsidwa ntchito, pansi pa COUP TEST, ngati ndi zida zothana ndi zodula kwambiri, tsamba lozungulira litha kukhala losalala.Amawerengedwa kuti tsambalo limakhala losalala, ndipo TDM TEST ndiyofunikira.Tiyenera kuzindikira kuti ngati magolovesi oletsa kudulidwawa atakhala ndi TDM TEST, "X" ikhoza kulembedwa pa nambala yachiwiri ya chithunzi cha certification.Panthawiyi, kukana kodulidwa kumangoyimiridwa ndi kalata yachisanu.Ngati si magolovu osagwira ntchito kwambiri, ndizotheka kuti zida za magolovuzi ziziziritsa tsamba la COUP TEST.Pakadali pano, TDM TEST ikhoza kusiyidwa.Nambala yachisanu ya mawonekedwe a certification ikuwonetsedwa ndi "X".

↑ Zida zamagalasi zosagwira ntchito kwambiri, palibe TDM TEST, ndipo palibe kuyesa kukana.

↑ Zida zama glovu zogwira ntchito kwambiri, TDM TEST yachitika, KUYESA kwa COUP ndi mayeso okana kukana sikunachitike.

Kulumikizana pakati pa miyezo yaku America ndi ku Europe.

American standard A1-A3 ndi European standard AC ndi ya low cut protection level, American standard A4-A5 ndi European standard E ndi ya medium cutting giredi, American standard A6-A9 ndi European standard F ndi apamwamba kudula giredi.
