Kunezinhlobo eziningi zamagilavu angazweli emakethe. Ingabe ikhwalithi yamagilavu anokumelana nokusikwa yinhle, iyiphi okungekho lula ukuyigqoka, nokuthi ungakhetha kanjani ukugwema ukukhetha okungalungile?
Amanye amagilavu amelana emakethe anegama elithi "CE" eliphrintwe ngemuva. Ingabe elithi "CE" lisho uhlobo oluthile lwesitifiketi sokuvumelana?
Uphawu lwe-"CE" yisitifiketi sokuphepha, esithathwa njengepasipoti yabakhiqizi ukuthi bavule futhi bangene emakethe yaseYurophu. I-CE isho ubunye baseYurophu (European Conformity). Ekuqaleni i-CE isho indinganiso yaseYurophu, ngakho-ke ngaphandle kokulandela indinganiso ye-en, yiziphi izinkambiso okufanele amagilavu amelana nokusikwa azilandele?
Amagilavu okuzivikela okuvikela ukulimala komshini ikakhulukazi athobelana ne-EN 388 ejwayelekile, inguqulo yakamuva inguqulo yango-2016, kanye ne-American standard ANSI/ISEA 105, inguqulo yakamuva nayo ingu-2016.
Kulezi zicaciso ezimbili, amafomu okuveza izinga lokumelana nokusikwa ahlukile.
Amagilavu angazweli esikwa aqinisekiswe yi-en standard azoba nephethini yesihlangu esikhulu enegama elithi "EN 388" kuso. Kunamadijithi angu-4 noma angu-6 edatha kanye nezinhlamvu zesiNgisi ngaphansi kwephethini yesihlangu esikhulu. Uma kuyidatha enamadijithi ayi-6 nezinhlamvu zesiNgisi, kukhombisa ukuthi kusetshenziswe imininingwane entsha ye-EN 388:2016, futhi uma iyizinombolo ezi-4, kukhombisa ukuthi kusetshenziswe imininingwane yakudala ka-2003.
Izincazelo zamadijithi ama-4 okuqala ziyefana, "ukumelana nemihuzuko", "ukumelana nokusika", "ukuqina", kanye "nokumelana nokubhoboza". Uma idatha inkulu, izici ziba ngcono.
Incwadi yesihlanu yesiNgisi iphinde ibonise "ukusika ukumelana", kodwa izinga lokuhlola lihlukile kunedijithi yesibili, futhi indlela yokubonisa izinga lokumelana nokusika ihlukile, okuzochazwa ngokuningiliziwe kamuva.
Incwadi yesithupha yesiNgisi ikhombisa "impact resistance", nayo ekhonjiswa ngezinhlamvu zesiNgisi. Kodwa idijithi yesithupha izovela kuphela uma ukuhlolwa komthelela kwenziwa, futhi uma kungenziwanga, kuzohlale kunamadijithi angu-5.
Nakuba inguqulo ka-2016 ye-en standard isisetshenziswe iminyaka engaphezu kwemine, kusenezinguqulo eziningi ezindala zamagilavu emakethe. Amagilavu amelana nokusikwa agunyazwe abasebenzisi abasha nabadala wonke angamagilavu afanelekayo, kodwa kunconywa kakhulu ukuthi uthenge amagilavu angavimbekiyo anamadijithi angu-6 nezinhlamvu ukukhombisa izici zegilavu.
Ngokufika kwenani elikhulu lezinto ezintsha, kuyadingeka ukuthi ukwazi ukuhlukanisa ngobuqili ukukhombisa ukumelana nokusikwa kwamagilavu. Endleleni entsha yokuhlukanisa ibanga, awukho umehluko phakathi kwe-A1-A3 kanye ne-1-3 yasekuqaleni, kodwa i-A4-A9 iqhathaniswa neyokuqala engu-4-5, futhi amabanga amabili okuqala ahlukaniswe amamaki asi-6, angasetshenziswa. amagilavu. Ukumelana nokusika kuveza isisho sesigaba esinemininingwane eminingi.
Esicacisweni se-ANSI, akulona nje kuphela uhlobo lwesisho lwezinga oluthuthukisiwe, kodwa nezinga lokuhlola. Ekuqaleni, ukuhlolwa kwakusebenzisa indinganiso ye-ASTM F1790-05, eyayivumela ukuhlolwa kumpahla ye-TDM-100 (izinga lokuhlola libizwa nge-TDM TEST) noma okokusebenza kwe-CPPT (izinga lokuhlola libizwa nge-COUP TEST). Manje isebenzisa indinganiso ye-ASTM F2992-15, evumela kuphela ukusetshenziswa kwe-TDM TEST kuqhuba ukuhlolwa.
✬Uyini umehluko phakathi kwe-TDM TEST kanye ne-COUP TEST?
I-COUP TEST isebenzisa i-blade eyindilinga enengcindezi engu-5 Copernicus ukuze iphendule futhi isike ezintweni zegilavu, kuyilapho i-TDM TEST isebenzisa ikhanda lommese ukuze icindezele okokusebenza kwegilavu ngezingcindezi ezihlukene, ibuyisela ngesivinini esingu-2.5 mm/s laser cutting
Nakuba i-EN 388 entsha idinga ukuthi izindinganiso ezimbili zokuhlola, i-COUP TEST kanye ne-TDM TEST, zingasetshenziswa, kodwa ngaphansi kwe-COUP TEST, uma kuyimpahla eluhlaza elwa ne-laser yokusika, i-blade eyindilinga ingase ibe buthuntu. Uma i-laser isika Ngemva kwemizuliswano engama-60, kubalwa ukuthi ikhanda lokusika liba buthuntu, futhi i-TDM TEST iyimpoqo.
Kumele kuqashelwe ukuthi uma le glovu esebenza kahle kakhulu yokunqanda i-laser isike yahlolwa i-TDM TEST, khona-ke okuthi "X" kungabhalwa kwidijithi yesibili yephethini yokuqinisekisa. Ngalesi sikhathi, ukumelana nokusika kuboniswa kuphela ngohlamvu lwesihlanu lwesiNgisi .
Uma kungewona amagilavu amahle kakhulu amelana, khona-ke okokusebenza kwamagilavu mancane amathuba okuthi kuthuntubeze ikhanda lokusika le-COUP TEST. Ngalesi sikhathi, i-TDM TEST ingashiywa, futhi idijithi yesihlanu yephethini yokuqinisekisa iboniswa ngokuthi "X".
Izinto ezisetshenziswayo zokusetshenziswa kwamagilavu angakwazi ukumelana nokusikwa azikahlolelwa TEST TEST noma ukumelana nomthelela. ↑ Impahla eluhlaza yamagilavu aqinile amelana, UKUHLOLA kwe-TDM Kwenziwe, UKUHLOLA KWE-COUP nokuhlolwa kokumelana nomthelela akuzange kwenziwe.
