Njengethuluzi lansuku zonke lezingane, ikhwalithi yama-backpacks ayihlobene nje nempilo yabo yomzimba, kodwa futhi nokuphepha kwempilo yabo. Kungumthwalo nesibopho sawo wonke umuntu osezingeni eliphezulu ukuhlola ikhwalithi nokuhlola ojosaka nokuvikela ukuphepha kwezinto ezinikezwa abafundi.
Amagama angukhiye alesi sihloko: ukuhlolwa kwe-backpack, ukuhlolwa kwe-backpack
01. Izindinganiso zokuhlola
Ukuhlolwa kojosaka babafundi ngokuvamile kusebenzisa indinganiso ye-QB/T 2858-2007 “Izikhwama Zezincwadi Zabafundi”, elungele ukubeka izincwadi zokufundisa, izinsiza zokufundisa, nezinto zokufundisa zabafundi, kanye namabhande ehlombe angawodwa nakabili kanye nezikhwama zezincwadi eziphathwayo. Ekuhlolweni nasekuhlolweni okuthile, isisekelo esijwayelekile esitholakalayo sihlanganisa: GB/T 2912.1 “Ukunqunywa kwe-Formaldehyde ku-Textiles – Ingxenye 1: I-Hydrolyzed Formaldehyde Yamahhala (Indlela Yokukhipha Amanzi)”, GB/T 3920 “Ukuhlola Ukushesha Kombala Kwemikhiqizo Yendwangu – Ukushesha Kombala kuya ku-Rubbing", GB 6675-2003 "I-National Toy Safety Technical Specification", GB 21207-2007 “Izimfuneko Ezijwayelekile Zokuphepha Eziphakelayo Zabafundi” QB/T 3826 “Indlela yokuhlola ukumelana nokugqwala yezingubo zensimbi kanye nezingubo ezifakwe ngamakhemikhali zemikhiqizo yezimboni ezilula – Indlela yokuhlola isifutho sikasawoti esimaphakathi (NSS)”, QB/T 3832 “Ukuhlola ukugqwala imiphumela yokuhlola yezingubo zensimbi zemikhiqizo yezimboni ezilula”, njll.
02. Amaphuzu okuhlola nezindlela
Izinkomba ezibalulekile zokuhlolwa kwekhwalithi yojosaka wabafundi zifaka ukuthwala isisindo, ukuwohloka, amandla okuthunga, ukushesha kombala ukungqubuzana, ukuphepha kwezinsiza, nokuqukethwe kwe-formaldehyde kwezisekeli zendwangu. Ukwengeza, ukunakwa kufanele kukhokhwe ekunethezekeni komhlane uma usebenzisa isikhwama, kanye nokusebenziseka kalula kwezintambo ze-backpack nezibambo.
Ngaphezu kokubhekisela ekuhlolweni kwemithwalo, kunamaphuzu amaningana okumele akhokhelwe ngokukhethekile ekuhlolweni kwama-backpacks. Izidingo zihluke kancane: izidingo zokubukeka - ikhwalithi yokubukeka kwesikhwama kufanele ihambisane nemithethonqubo elandelayo: ukubukeka okuphelele, ukuma okugcwele, imigqa ecacile, ukunamathela okuyisicaba nokubushelelezi, ubuqotho, nokuhlanzeka okuphelele. Uziphu, onezikhala ezinqenqemeni ezingashintshi, ukuthungwa okuqondile, awekho amazinyo angekho noma angekho, nokudonsa nokuvala okushelelayo. Izesekeli nokufakwa kufanele kube nendawo ebushelelezi, ekhanyayo futhi engenazo izinsalela zokugqwala, i-plating egejiwe, izimbobo yenaliti, amabhamuza, axebukayo, futhi ahlukane. Izesekeli kufanele zifakwe ngokuqinile. Imigqa ye-Suture kufanele ifanele ikhwalithi yendwangu kanye nomugqa osetshenzisiwe, ngekhwalithi nombala ohambisana nengxenye ngayinye. Indwangu akufanele ibe ne-warp ephukile noma i-weft, futhi akufanele yeqe izintambo, izintambo, amamaki, amabala, noma amabala. Ukubukeka kokuphrinta kudinga amaphethini acacile, imibala egqamile, ukuphrinta ngokweqile okulungile, akukho uyinki ogelezayo noma oveziwe, futhi akukho mbala ofiphalayo. I-Suture stitches kufanele ihambisane nezintambo ezingenhla neziphansi, nezithunga eziqondile kanye nokuhlukana kwezinaliti okungaguquki. Izithungo ezingenalutho noma izithungo ezeqiwe azivunyelwe endaweni enkulu yangaphambili nekhava yangaphambili yesikhwama sezincwadi. Akukho ukuthunga okusontiwe okwedlula u-12mm ubude okuvunyelwe. Umkhiqizo owodwa akufanele ube nenaliti engaphezu kweyodwa engenalutho noma inaliti engekho, nezinaliti ezingenalutho ezingaphezu kwezimbili, izinaliti ezingekho, noma izinaliti ezeqiwe.
Ukuhlolwa kokuthwala imithwalo - Ukuhlolwa kokuthwala imithwalo yezikhwama zabafundi kudinga ukuthi izibambo, izintambo, izintambo zokulungisa, namahhuku akufanele ziwe noma ziphuke ngaphansi komthwalo oshiwo, futhi umzimba wesikhwama akufanele uqhekeke.
Izidingo zesisindo zimi kanje:
Ukucaciswa Kwenombolo Yomkhiqizo (ubude)/mm Umthwalo/kg1＜30032300-400 (ngaphandle kwe-400) 53400-50074＞50010
Ukuhlolwa kwe-Swing - Ubhaka ulayishwa ngokwemithethonqubo, futhi izintambo nezibambo zihlolwa ngokwehlukana: zilenga emoyeni, izintambo zisesimweni eside kunazo zonke, noma ulungise ibanga ukusuka ku-axis swing kuya ku-50cm-60cm, swing izikhathi ezingu-30 ( phambili nangemuva njengesikhathi esingu-1), kanti i-engeli yokujika ingu (60 ± 3) °. Ngemva kokuma kwe-swing, hlola ukuthi amabhande kabhaka, izibambo, izintambo zokulungisa, namahhuku avikelekile yini. Linganisa ukuthi ingabe ukuguqulwa kwengxenye yokuxhuma kudlula u-20% uma kuqhathaniswa nobude bangempela phakathi kwamaminithi angu-2. Ukuhlolwa kwe-Static and drop - Kala ubude bezingxenye ezisebenza njengezixhumanisi kubhaka. Ubhaka kufanele ulayishwe izikhathi ezingu-1.2 isisindo esishiwo, umiswe emoyeni (ngebhande esimweni eside kunazo zonke), futhi phansi kwesikhwama kufanele kube ngu-60cm ngaphezu komhlaba (ngendawo yokhuni eqinile), ukuze ilingane. ucindezelekile futhi usesimweni esimile nesiqondile. Ngemuva kwemizuzu engama-30, yehlisa uqonde futhi uhlole ukuthi izintambo, izibambo, izintambo zokulungisa, namaketanga kuvikelekile yini. Linganisa ubude bezintambo, izibambo, izintambo zokulungisa, namaketango asebenza njengokuxhumana phakathi kwemizuzu engu-2, futhi uhlole ukuthi ukuguqulwa kudlula u-20% uma kuqhathaniswa nobude bokuqala.
