Indlela elula yokuchonga yoMgangatho weeHelmethi zesithuthuthu
Izigcina-ntloko ezisemgangathweni azinayo i-logo esisigxina kuphela, kodwa umxholo olandelayo: Igama lemveliso, igama lomzi-mveliso, indawo, iimpawu zokuthengisa, iintlobo zemveliso, imodeli yemveliso, iinkcukacha kunye nenombolo yelayisensi yokuvelisa.Iimpawu zomgangatho ophantsi we-helmets aziphelelanga.
Izigcina-ntloko ezisemgangathweni, ukhetho lwempahla ye-FRP okanye i-ABC Engineering Plastics, iiGoggles ze-PC ye-velvet yeplastiki, ngokwemigangatho kazwelonke iphinda iqhube unyango olunzima ukwandisa amandla.Umgangatho ophantsi wee-helmets, ukhetho luhlaziywa ngokutsha okanye iplastiki eqhelekileyo, kwaye ngaphandle kokuqina kwonyango.
Indlela elula yokuchonga:
(I-1 enezikhonkwane kwinto enzima yeso ngokubanzi, musa ukushiya imikrwelo esemgangathweni.)
2 Inkcazo yokuguqulwa kwegobolondo enempembelelo encinci yi-liepin.
(Izigcina-ntloko ezi-3 zomgangatho olungileyo, umaleko okhuselayo usebenzisa izinto ezingeyotyhefu ezingenabungozi, umgangatho wobungakanani, igranule icoleke kakhulu (ngokubanzi ayibi ngaphezu kwe-3 millimeters), inokufunxa awona mandla ongquzulwano ngeyona ndlela ilungileyo, iphucula ubunzulu bomntu. , umaleko okhuselayo we-foam coarse particles, awukwazi ukufunxa ngokufanelekileyo amandla empembelelo, ukunyanzeliswa kwe-extrusion.
Ukukhwela isithuthuthu eJapan kuya kuba nomkhwa olungileyo wokunxiba izigcina-ntloko, kwanomfundi okhwele ibhayisekile uya kuziva enxibe izigcina-ntloko.Umsebenzi wezigcina-ntloko kukukhusela intloko yomqhubi, kunye nokuthintela imvula kunye nekhephu ebusika obubandayo, ukuphepha uthuli emoyeni okanye izinto eziphaphazelayo emehlweni, umsebenzi wokutshatyalaliswa kobushushu beHan nawo ulungile kakhulu. .
Okwangoku, imveliso yelizwe lethu yokhuselo lwezithuthuthu isimbo isimboli iimpawu ezininzi, kuphela ukusuka umsebenzi zinokwahlulwa zibe izigcina-ntloko ezipheleleyo (uhlobo oluvaliweyo ngokupheleleyo), izigcina-ntloko zesiqingatha (eziqhelekileyo), izigcina-ntloko ezikhethekileyo ezenziwe ngokwezifiso (ezifana ne-electronic sober type) .Ukwahlulwa kweenqwelo-mafutha kunokwahlulwa ngokwezigqoko eziqhelekileyo zesithuthuthu, ii-helmets zabantwana, ii-helmets zokhuseleko, ii-helmets zabasetyhini, ii-helmets zezemidlalo, ii-helmets zomdyarho, ii-helmets zorhwebo, iintlobo zokhuphiswano olunqamlezileyo kunye nezigcina-ntloko zokhuphiswano.Eyangaphambili yeyoyilo oluqhelekileyo, isicelo sokuyila sisezantsi, esokugqibela sesoyilo olukhethekileyo, isicelo soyilo siphezulu.
