ukunitha okusebenzayo kwezingubo zobuhle isici njengokusetshenziswa kwezindwangu eziluka ze-spandex

umsebenzi ukunitha ubuhle izingubo isici njengoba isicelo spandex ezinithiwe izindwangu, umsebenzi wayo iye futhi kancane kancane ithuthukiswe umzimba plastic, ngokusebenzisa ukushumeka indwangu spandex knitted, kungaba ukwakha umzimba plastic uhlobo lwezingubo ezinithiwe, futhi kungaba baphathe Buttock, isisu ukusebenza , futhi emakethe yezimpahla zamanje ithatha ingxenye enkulu yokuthengisa.Ngesikhathi esifanayo, i-spandex inomphumela wokuzivikela we-thrombus, okwenza amasokisi ama-knitted aqukethe i-spandex adume.Kungenxa yokulungiswa kokufaka kwe-spandex, amandla okucindezela okunwebekayo akhuphuka kancane kancane kusukela ekugcineni okungaphezulu kwamasokisi ahlanganisiwe kuya ekugcineni okuphansi, ukuze kuthuthukiswe ukugeleza kwegazi lesitho, ukuze kuzuzwe umphumela wokusebenza wokuvimbela i-thrombus.
Umehluko phakathi kwe-European standard EN388 kanye ne-American standard ANSI/ISEA105
Kulawa mazinga amabili, ukuvezwa kwezinga lokumelana nokusika kuhlukile.

Amagilavu ​​amelana nokusikwa agunyazwe izinga laseYurophu azoba nomfanekiso wesihlangu onamagama athi “EN 388″ kuwo.Kunezinombolo ezi-4 noma ezi-6 nezinhlamvu ngaphansi kwesithombe sesihlangu.Uma kuyizinhlamvu eziyisi-6 nezinhlamvu, kusho ukuthi izinga le-EN 388:2016 lakamuva liyasetshenziswa.Uma inamadijithi angu-4, kusho ukuthi yizinga elidala lika-2003.

↑ Isithombe esingakwesokunxele yizinga elidala, futhi isithombe esingakwesokudla siyindinganiso entsha.
Amadijithi angu-4 okuqala anencazelo efanayo, “ukumelana nokugqoka”, “ukumelana nokusika”, “ukumelana nezinyembezi”, “nokumelana nokubhobozwa”.Uma inombolo enkulu, ukusebenza kangcono.Incwadi yesihlanu ibuye isho "ukumelana nokusika", kodwa indlela yokuhlola ihlukile kunedijithi yesibili, futhi ukumelwa kwebanga lokumelana nokusikwa nakho kuhlukile, okuzoxoxwa ngakho ngokuningiliziwe kamuva.Uhlamvu lwesithupha lumele “ukumelana nomthelela” futhi lumelwe nezinhlamvu.Kodwa-ke, kuzoba nedijithi yesithupha kuphela uma kwenziwa ukuhlolwa kokumelana nomthelela.Uma kungenziwanga, kuzoba namadijithi ayi-5 kuphela.Nakuba inguqulo ka-2016 yezinga laseYurophu isetshenziswe iminyaka engaphezu kwengu-4, kusenezinguqulo eziningi ezindala zamagilavu ​​emakethe.Amagilavu ​​amelana nokusikwa agunyazwe izindinganiso ezintsha nezindala wonke angamagilavu ​​afanelekayo, kodwa kunconywa kakhulu ukuthenga amagilavu ​​angagodli asebenzisa izinombolo ezinamadijithi angu-6 nezinhlamvu ukukhombisa ukusebenza kwamagilavu.Isisho saseMelika esijwayelekile se-ANSI 105.

Ngo-2016, i-American standard ANSI 105 nayo ibuyekeziwe.Izinga langempela lokumelana nokusikwa belimelwe ngu-1-5 emfanekisweni wesihlangu, futhi manje limelelwa i-“A1” kuya ku-“A9”.Ngokufanayo, inani elikhulu, liphakeme izinga lokumelana nokusika.

Kodwa kungani ubuyekeza indlela yokuhlukanisa isuka kumazinga ayi-5 iye kumazinga ayi-9?Isizathu siwukuthi ngokuvela kwezinto ezintsha ezengeziwe, ukuhlukaniswa okuningiliziwe kuyadingeka ukuze kuboniswe ukumelana nokusikwa kwamagilavu.Endleleni entsha yokugreda, i-A1-A3 ngokuyisisekelo iyafana neyokuqala engu-1-3, kodwa uma iqhathaniswa neyokuqala engu-4-5, i-A4-A9 isebenzisa amamaki ayi-6 ukuze ihlukanise ibanga lokuqala lebanga lesi-2, elingamelana namagilavu.Sika ubulili ukuze ubonise isimo esihle kakhulu.Esilinganisweni se-ANSI, isibuyekezo asikona nje ukuvezwa kwezinga, kodwa futhi indlela yokuhlola.Ukuhlola kwangempela kusetshenziswe indinganiso ye-ASTM F1790-05, evumela ukuhlolwa emshinini we-TDM-100 (indlela yokuhlola ibizwa ngokuthi i-TDM TEST) noma umshini we-CPPT (indlela yokuhlola ibizwa ngokuthi yi-COUP TEST), manje kusetshenziswa indinganiso ye-ASTM F2992-15, yi-TDM kuphela esetshenziswayo. kuvunyelwe i-TEST ukuthi ihlole.Uyini umehluko phakathi kwe-TDM TEST kanye ne-COUP TEST?

I-COUP TEST isebenzisa i-blade eyindilinga enokucindezela kwama-Newtons angu-5 ukuze igiqe futhi isike ezintweni zegilavu, kuyilapho i-TDM TEST isebenzisa i-blade ukuze icindezele okokusebenza kwegilavu ​​ngezingcindezi ezihlukene, ukusika emuva naphambili ngokuvundlile ngesivinini esingu-2.5 mm/s. .Nakuba izinga elisha laseYurophu i-EN 388 libeka ukuthi izindlela ezimbili zokuhlola, i-COUP TEST kanye ne-TDM TEST, zingasetshenziswa, ngaphansi kwe-COUP TEST, uma kuyimpahla esebenza kahle emelene nokusika, i-blade eyindilinga ingase ibe buthuntu.Kubalwa ukuthi i-blade iba buthuntu, futhi TEST TEST iyadingeka.Kufanele kuqashelwe ukuthi uma le gilavu ​​elwa nokusika esebenza kahle kakhulu ihlolwe i-TDM, u-“X” ungabhalwa edijithini yesibili yomfanekiso wokuqinisekisa.Ngalesi sikhathi, ukumelana nokusika kumelelwa kuphela uhlamvu lwesihlanu.Uma kungelona igilavu ​​elikwazi ukumelana nokusebenza kahle kokusika, akunakwenzeka ukuthi okokusebenza kwegilavu ​​kuthuntubeze i-CUP TEST blade.Ngalesi sikhathi, i-TDM TEST ingakhishwa.Idijithi yesihlanu yephethini yesitifiketi ikhonjiswe ngo-“X”.

↑ Impahla yamagilavu ​​engasebenzi kahle kakhulu, ayikho TEST ye-TDM, futhi akukho sivivinyo sokumelana nomthelela.

↑ Izinto zamagilavu ​​ezisikwa ezisebenza kahle kakhulu, UKUHLOLA kwe-TDM kwenziwe, UKUHLOLWA KWE-COUP nokuhlola ukumelana nomthelela akuzange kwenziwe.

Ukuxhumana phakathi kwezindinganiso zaseMelika nezaseYurophu.

I-American standard i-A1-A3 kanye ne-European standard AC ingeyezinga lokuvikela elisikiwe eliphansi, izinga laseMelika i-A4-A5 kanye ne-European standard E liyibanga eliphakathi lokuvikela, izinga laseMelika i-A6-A9 kanye ne-European standard F ingeyebanga eliphakeme lokusika.
