imikorere yububoshyi bwimyenda yimyambarire nkibikorwa byo kwambara imyenda ya spandex

imikorere yububoshyi bwimyenda yububiko nkugukoresha imyenda ya spandex yububiko, imikorere yayo nayo yagiye itera imbere buhoro buhoro umubiri wa pulasitike, binyuze mu gushiramo imyenda iboshye ya spandex, irashobora gukora ubwoko bwumubiri wa plastike yimyenda iboshye, kandi irashobora gutwara ikibuno, inda mubikorwa. , no kumasoko yimyenda yubu afite igice kinini cyibicuruzwa. Muri icyo gihe, spandex igira ingaruka zo kwirwanaho ya trombus, nayo ituma amasogisi yububoshyi arimo spandex akundwa. Binyuze muguhindura kwinjiza spandex, imbaraga zo kwikuramo elastike zigenda ziyongera buhoro buhoro kuva kumpera yo hejuru yisogisi iboheye kugeza kumpera yo hepfo, kugirango turusheho kunoza umuvuduko wamaraso yingingo, kugirango ugere kubikorwa byogukumira trombus.
Itandukaniro riri hagati yuburayi EN388 nubusanzwe Abanyamerika ANSI / ISEA105
Muri ibi bipimo byombi, imvugo yurwego rwo kugabanya kurwanya iratandukanye。

Uturindantoki twirinda gukata byemejwe n’ibipimo by’i Burayi bizaba bifite igishushanyo mbonera cyanditseho “EN 388 ″. Hano hari imibare 4 cyangwa 6 ninyuguti munsi yikingira. Niba ari imibare 6 ninyuguti, bivuze ko ikoreshwa rya EN 388: 2016 rigezweho. Niba ari imibare 4, bivuze ko aribisanzwe 2003.

Picture Ishusho ibumoso nigipimo gishaje, naho ishusho iburyo nigipimo gishya.
Imibare 4 ibanza ifite ibisobanuro bimwe, aribyo "kwambara birwanya", "guca ukubiri", "kurwanya amarira", no "gucumita." Umubare munini, niko imikorere myiza. Ibaruwa ya gatanu isobanura kandi "guca ukurwanya", ariko uburyo bwo kwipimisha buratandukanye nubwa kabiri, kandi guhagararirwa kurwego rwo kugabanuka byaciwe nabyo biratandukanye, bizaganirwaho muburyo burambuye nyuma. Ibaruwa ya gatandatu isobanura "kurwanya ingaruka" kandi igaragazwa ninyuguti. Ariko, hazabaho imibare ya gatandatu gusa mugihe ikizamini cyo kurwanya ingaruka cyakozwe. Niba bidakozwe, hazaba imibare 5 gusa. Nubwo verisiyo yuburayi ya 2016 yakoreshejwe mumyaka irenga 4, haracyari verisiyo nyinshi za kera za gants ku isoko. Uturindantoki twirinda gukata byemejwe nubuziranenge bushya kandi bwa kera byose ni uturindantoki twujuje ibyangombwa, ariko birasabwa cyane kugura uturindantoki twirinda gukata dukoresha imibare 6 n’inyuguti byerekana imikorere ya gants. Imvugo y'Abanyamerika ANSI 105 imvugo.

Muri 2016, Abanyamerika basanzwe ANSI 105 nabo bakoze ivugurura. Urwego rwambere rwaciwe rwo guhangana rwerekanwe na 1-5 mubishushanyo mbonera, none ihagarariwe na “A1 ″ kugeza“ A9 ″. Muri ubwo buryo ,, uko umubare munini, niko urwego rwo kugabanya kurwanya.

Ariko ni ukubera iki kuvugurura uburyo bwo gutondekanya kuva kurwego 5 kugeza kurwego 9? Impamvu nuko hamwe havutse ibikoresho byinshi bishya, hasabwa ibyiciro birambuye kugirango werekane kugabanuka kwa gants. Muburyo bushya bwo gutanga amanota, A1-A3 mubyukuri ni kimwe na 1-3 yambere, ariko ugereranije numwimerere 4-5, A4-A9 ikoresha amanota 6 kugirango igabanye icyiciro cya mbere cyambere, gishobora kwihanganira uturindantoki. Kata igitsina kugirango ugaragaze amanota meza. Mubisanzwe bya ANSI, kuvugurura ntabwo ari imvugo yurwego gusa, ahubwo nuburyo bwo kugerageza. Ikizamini cyumwimerere cyakoresheje ASTM F1790-05 gisanzwe, cyemerera kwipimisha kumashini ya TDM-100 (uburyo bwikizamini bwitwa TDM TEST) cyangwa imashini ya CPPT (uburyo bwikizamini bwitwa COUP TEST), ubu harakoreshwa ASTM F2992-15, gusa TDM ni yemereye Ikizamini. Ni irihe tandukaniro riri hagati y'Ikizamini cya TDM n'IKIZAMINI CY'IGIKOMBE?

IKIZAMINI CY'IGIKOMBE gikoresha icyuma kizunguruka gifite umuvuduko wa 5 Newtons kugirango uzunguruke kandi ugabanye ibikoresho bya gants, mugihe TDM TEST ikoresha icyuma kugirango ikande ku bikoresho bya gants hamwe n’umuvuduko utandukanye, uca inyuma kandi utambitse ku muvuduko wa mm 2,5 / s . Nubwo igipimo gishya cy’iburayi EN 388 giteganya ko uburyo bubiri bwikizamini, COUP TEST na TDM TEST, bushobora gukoreshwa, munsi ya COUP TEST, niba ari ibikoresho bihanitse birwanya gukata, icyuma kizenguruka gishobora guhinduka. Irabarwa ko icyuma gihinduka, kandi IKIZAMINI cya TDM ni itegeko. Twabibutsa ko niba iyi globe ikora cyane yo kurwanya gukata ikizamini cya TDM, “X” irashobora kwandikwa kumibare ya kabiri yerekana impamyabumenyi. Muri iki gihe, kurwanya gukata kugaragazwa gusa ninyuguti ya gatanu. Niba atari imikorere-yo hejuru yo gukata-kwihanganira gants, ntibishoboka ko ibikoresho bya gants bizahindura icyuma cya COUP. Muri iki gihe, IKIZAMINI cya TDM kirashobora kuvaho. Umubare wa gatanu wuburyo bwo kwemeza werekanwa na “X”.

↑ Ibidakorwa neza-birwanya gukata gants, nta kizamini cya TDM, kandi nta kizamini cyo kurwanya ingaruka.

Material Ibikoresho byo mu rwego rwo hejuru bikata-birinda gants, Ikizamini cya TDM cyarakozwe, IKIZAMINI CY'IGIKOMBE hamwe n’ibizamini byo kurwanya ingaruka ntibyakozwe.

Kwandikirana hagati yuburinganire bwabanyamerika nu Burayi.

Igipimo cy’abanyamerika A1-A3 hamwe n’ibipimo ngenderwaho by’iburayi biri mu rwego rwo kurinda umutekano muke, igipimo cy’abanyamerika A4-A5 n’Uburayi E kiri mu cyiciro cyo gukingira hagati, Abanyamerika A6-A9 n’ibipimo by’iburayi F biri mu rwego rwo hejuru rwo gukata.
