ukunitha okusebenzayo inkalo yempahla yobuhle njengosetyenziso lwelaphu ezinithiweyo ze-spandex

Ukunitha okusebenzayo kwempahla yobuhle njengokusetyenziswa kwamalaphu ezinithiweyo e-spandex, umsebenzi wawo uye waphuhliswa ngokuthe ngcembe umzimba weplastiki, ngokudibanisa ilaphu elinithiweyo le-spandex, unokwenza uhlobo lomzimba weplastiki weempahla ezinithiweyo, kwaye unokuthwala impundu, isisu sisebenza. , kwaye kwimarike yempahla yangoku ithatha inxalenye enkulu yokuthengisa. Ngelo xesha, i-spandex inefuthe lokukhusela i-thrombus, eyenza iikawusi ezinithiweyo ezine-spandex zithandwa. Kungokuhlengahlengiswa kwegalelo le-spandex, amandla okunyanzeliswa kwe-elastic anyuka ngokuthe ngcembe ukusuka kwinqanaba eliphezulu leesokisi ezidibeneyo ukuya kwinqanaba elingaphantsi, ukwenzela ukuba kuphuculwe ngakumbi ukuhamba kwegazi kwelungu, ukuze kufezekiswe umphumo osebenzayo wokuthintela i-thrombus.
Umahluko phakathi komgangatho waseYurophu we-EN388 kunye ne-American standard ANSI/ISEA105
Kule migangatho mibini, ukubonakaliswa kwenqanaba lokumelana nokusika kuyahluka.

Iiglavu ezikwaziyo ukusika eziqinisekisiweyo ngumgangatho waseYurophu ziya kuba nomzobo wekhaka onamagama "EN 388" kuyo. Kukho amanani ama-4 okanye ama-6 kunye nonobumba phantsi komzobo wekhaka. Ukuba ngamadijithi ama-6 kunye nonobumba, oko kuthetha ukuba umgangatho wamva nje we-EN 388:2016 usetyenziswa. Ukuba inamanani ama-4, oko kuthetha ukuba ngumgangatho omdala ka-2003.

↑ Umfanekiso ongasekhohlo ngumgangatho omdala, kwaye umfanekiso osekunene ngumgangatho omtsha.
Amanani ama-4 okuqala anentsingiselo efanayo, "ukumelana nokunxiba", "ukumelana nokusika", "ukumelana nokukrazula", kunye "nokumelana nokuhlatywa". Ukuba likhulu inani, ngcono ukusebenza. Ileta yesihlanu ikwathetha "ukuchasana nokusika", kodwa indlela yokuvavanya ihluke kwidijithi yesibini, kwaye ukubonakaliswa kwebakala lokumelana nokusikwa kukwahlukileyo, okuya kuxutyushwa ngokubanzi kamva. Unobumba wesithandathu umele “ukuchasana nempembelelo” kwaye ukwamelwe ngoonobumba. Nangona kunjalo, kuya kubakho idijithi yesithandathu kuphela ukuba uvavanyo lokumelana nempembelelo luyenziwa. Ukuba ayiqhutywa, kuya kubakho amanani ama-5 kuphela. Nangona inguqu ye-2016 yomgangatho waseYurophu isetyenziswe ngaphezu kweminyaka eyi-4, kusekho iinguqulelo ezininzi ezindala zeeglavu kwiimarike. Iiglavu ezinqambileyo ezingqinisiswe yimigangatho emitsha kunye neyokudala zonke iiglavu ezifanelekileyo, kodwa kucetyiswa ngakumbi ukuthenga iiglavu ezinqambileyo ezisebenzisa iinombolo ze-6 kunye neeleta ukubonisa ukusebenza kweeglavu. Umgangatho waseMelika we-ANSI 105 intetho.

Kwi-2016, umgangatho waseMelika we-ANSI 105 uphinde wahlaziywa. Inqanaba lokuqala lokuchasana lokusikwa lalimelwe ngu-1-5 kumzobo wekhaka, kwaye ngoku imelwe ngu "A1" ukuya "A9". Ngokufanayo, inani elikhulu, liphezulu izinga lokumelana nokusika.

Kodwa kutheni uhlaziywa indlela yokuhlela ukusuka kumanqanaba ama-5 ukuya kumanqanaba ali-9? Isizathu kukuba ngokuvela kwezinto ezintsha ezininzi, ulwahlulo olucacileyo luyafuneka ukubonisa ukuxhathisa ukusikwa kweeglavu. Kwindlela entsha yokuhlela, i-A1-A3 ngokusisiseko iyafana neyokuqala 1-3, kodwa xa ithelekiswa ne-4-5 yoqobo, i-A4-A9 isebenzisa amabakala ama-6 ukwahlula udidi lokuqala lwebakala lesi-2, olunokumelana neeglavu. Sika isini ukuze ube nembonakalo ephucukileyo. Kumgangatho we-ANSI, ukuhlaziywa akukona nje ukubonakaliswa kwenqanaba, kodwa kunye nendlela yokuvavanya. Uvavanyo lwangaphambili lusetyenziswe umgangatho we-ASTM F1790-05, ovumela ukuvavanywa kumatshini we-TDM-100 (indlela yokuvavanya ibizwa ngokuba yi-TDM TEST) okanye umatshini we-CPPT (indlela yovavanyo ibizwa ngokuba yi-COUP TEST), ngoku i-ASTM F2992-15 standard isetyenziswa, kuphela i-TDM kuphela. kuvunyelwe TEST ukuvavanya. Yintoni umahluko phakathi kovavanyo lwe-TDM kunye novavanyo lwe-COUP?

I-COUP TEST isebenzisa i-circular blade kunye noxinzelelo lwe-5 Newtons ukuqengqeleka kunye nokusika izinto zeglavu, ngelixa i-TDM TEST isebenzisa i-blade ukucinezela izinto zeglavu kunye noxinzelelo oluhlukeneyo, ukusika emva nangaphezulu ngokuthe tye kwisantya se-2.5 mm / s. . Nangona umgangatho omtsha waseYurophu we-EN 388 uchaza ukuba iindlela ezimbini zovavanyo, i-COUP TEST kunye ne-TDM TEST, zingasetyenziswa, phantsi kwe-COUP TEST, ukuba yinto ephezulu yokusebenza yokuchasana nokusika, i-blade ejikelezayo ingaba buthuntu. Kubalwa ukuba i-blade iba buthuntu, kwaye i-TDM TEST inyanzelekile. Kufuneka kuqatshelwe ukuba ukuba le glavu i-anti-cut cut-high-performance TEST ifumene i-TDM TEST, "X" ingabhalwa kwidijithi yesibini yegraphic certification. Ngeli xesha, ukuchasana kokusika kumelelwe kuphela unobumba wesihlanu. Ukuba asiyoglovu ekwaziyo ukumelana nomsebenzi ophezulu, akunakwenzeka ukuba imathiriyeli yeglavu iyenze buthuntu iblade ye-COUP TEST. Ngeli xesha, TDM TEST inokushiyeka. Idijithi yesihlanu yepateni yesatifikethi iboniswa ngu "X".

↑ Izinto zeglavu ezingasebenziyo eziphezulu, akukho TEST ye-TDM, kwaye akukho vavanyo lokumelana nempembelelo.

↑ Isixhobo seglavu esisikiweyo esisebenza ngokuphezulu, uvavanyo lwe-TDM luye lwaqhutywa, UVAVANYO lwe-COUP kunye neemvavanyo zokumelana nempembelelo azizange zenziwe.

Imbalelwano phakathi kwemigangatho yaseMelika neyaseYurophu.

Umgangatho waseMelika i-A1-A3 kunye nomgangatho waseYurophu we-AC ukwinqanaba elisezantsi lokhuseleko, umgangatho waseMelika i-A4-A5 kunye nomgangatho waseYurophu u-E ukwinqanaba eliphakathi lokhuseleko lokusikwa, umgangatho waseMelika i-A6-A9 kunye nomgangatho waseYurophu ongu-F ukwinqanaba eliphezulu lokusikwa.
