Uma uthenga izicathulo zokuphepha, okukhethwa kukho kokuqala yi-toe cap: insimbi noma i-composite. Zombili zihlolwa ngezinga elifanayo lokushayeka elingu-200-joule ngaphansi kwe-SANS 20345, ngakho zombili zigcina izinzwane zakho ziphephile. Umehluko usemininingwaneni.
Izindwangu zezinzwane zensimbi
Ubuchwepheshe: buhlolwe, buqinile ngokwedlulele, bucwebezela (indawo eningi ebhokisini lezinzwane), futhi imvamisa buyathengeka kakhulu. Okubi: bunzima kakhulu, buqhuba ukushisa namakhaza, futhi buzodala ukuthi izitholi zensimbi zikhale.
Okulungele: ukwakha, ukumba, nomsebenzi omkhulu wezimboni lapho ukuqina okuphezulu nenani kubalulekile. Phequlula izicathulo zethu zokuphepha ezinensimbi ezinzwaneni.
Izindwangu zezinzwane ze-composite
Kwenziwe ngezinto ezingezona insimbi njenge-Kevlar, i-fibreglass noma i-carbon fibre. Ubuchwepheshe: bushelelezi (ukukhathala okuncane ngesikhathi eside sokusebenza), abuqhubi izinga lokushisa, futhi zisebenza nezitholi zensimbi. Okubi: ibhokisi lezinzwane elikhudlwana kancane futhi imvamisa intengo ephakeme.
Okulungele: izikhumulo zezindiza nokuhlola ukuphepha, umsebenzi kagesi, ukugcina okubandayo noma izinga lokushisa langaphandle elidlulele, nanoma ubani ofuna isicathulo esishelelezi ngangokunokwenzeka.
Umhlahlandlela osheshayo wokuthatha isinqumo
- Ufuna okukhethwa kukho okuqinile kakhulu, okunani elingcono kakhulu? Insimbi.
- Udlula ezitholi zensimbi noma usebenza emazingeni okushisa aphezulu? I-Composite.
- Umi ngezinyawo amahora angu-10+ futhi ufuna ukukhathala okuncane? I-Composite.
- Isabelomali esincane, umsebenzi wendawo ongahlanzekile? Insimbi.
Noma yikuphi okhethayo, qiniseka ukuthi kunesitifiketi esivumelekile se-NRCS noma se-SABS. Usangabaza? Xhumana nathi futhi sizokusiza ukukhetha.
