Lapho usebenza ezindaweni ezinzima neziyingozi, amabhuzu emvula e-PVC okuphepha ayisinqumo esihle sokuhlala uphephile futhi unethezekile. Enye yezinketho ezingcono kakhulu emakethe amabhuzu emvula amnyama angu-40cm ubude obuphelele be-PVC anozwane lwensimbi kanye ne-midsole yensimbi. Kungamabhuzu okuqala e-PVC okusebenza ukuthola isitifiketi se-CSA e-China, isitifiketi esifanelekile se-CSA Z195-14. Isitifiketi se-CSA Z195-14 siwuphawu lokuvelela ezicathulweni zokuphepha ezinozwane lwensimbi nemboni yamapuleti. Lokhu kusho ukuthi izicathulo zokuphepha ziye zahlolwa kanzima futhi zihlangabezana nezindinganiso zokuphepha, okuqinisekisa ukuthi zinganikeza ukuvikeleka okudingekayo kunoma yisiphi isimo sokusebenza. Ngesitifiketi sayo se-CSA, ungaqiniseka ukuthi uthenga umkhiqizo wekhwalithi ephezulu, onokwethenjelwa ohlangabezana namazinga aphezulu okuphepha.
Amabhuzu ensimbi okuphepha kwezinzwane abe yisitayela sakudala sokuvikela abasebenzi ezimbonini ezahlukahlukene iminyaka eminingi. Ngokuklama kwazo okuhlala isikhathi eside futhi okusebenzayo, lezi zicathulo zemvula zensimbi ezingasheleli ezingasheleli seziphenduke izinto ezibalulekile emsebenzini. Esinye sezizathuI-CSA steel toe rubber bootsathandwa kakhulu ukuqina kwawo kanye nekhono lawo lokunikeza isivikelo ezingozini ezihlukahlukene zasemsebenzini. Ngaphezu kwalokho, impahla ye-PVC iyaziwa ngokuphinda isetshenziswe kanye nobungane bemvelo. Ngokusebenzisa amabhuzu e-PVC, izinkampani zingabamba iqhaza ngenkuthalo ezinhlelweni zokuphinda zisetshenziswe futhi zinciphise indawo yazo yekhabhoni.
Ubuchwepheshe bamabhuzu okusebenza e-PVC amnyama angangeni manzi yisakhiwo sawo sokubumba umjovo wesikhathi esisodwa, esiqinisekisa izindawo zabo zokungangeni kwamanzi kanye nokungalunywa. Ukwengeza, lawa mabhuzu afakwe izikepisi zensimbi ezikwazi ukumelana nomthelela ofika ku-125J, okuwenza afaneleke kahle endaweni lapho kusingathwa khona izinto ezisindayo. Ngaphezu kwalokho, i-midsole yensimbi kumabhuzu e-PVC inikeza ukumelana nokungena okufika ku-1100N, ukuvimbela izinto ezibukhali emhlabathini ukuthi zingabangeli umonakalo. Ama-gumboots ane-steel toe cap aphinde aklanyelwe ukunikeza umsebenzi we-antistatic oqinisekisa ukuthi anokumelana no-100 kΩ-1000 MΩ, okuwavumela ukuthi asetshenziswe ngokuphepha ezindaweni zokukhipha i-static.
Amabhuzu ethu enjoloba agunyazwe yi-CSA abe abathengi abaphambili e-Canada iminyaka engaphezu kweshumi. Imikhiqizo yethu ihlolwe ngokuqinile ngamakhasimende kanye nemakethe, okufakazela ikhwalithi nokuthembeka kwayo okungenakuqhathaniswa. Njengomkhiqizi ochwepheshe webhuthi yemvula yokuphepha, asibeki phambili kuphela ikhwalithi yezicathulo kodwa futhi sinikeza isevisi enokwethenjelwa ngemva kokuthengisa ukuze siqinisekise ukwaneliseka okukhulu kwamakhasimende. Ngaphezu kwalokho, imikhiqizo yethu iyalandeleka ngokugcwele, ifaka ukuzethemba kwabangenayo mayelana nobuqotho bezimpahla.
Ngaphezu kwalokho, ithimba lethu elizinikele nelinolwazi lokuthengisa izinto ezithunyelwa ngaphandle lizibophezele ekunikezeni isevisi yokunaka nephumelelayo ukuhlangabezana nezidingo zamakhasimende ethu avela emakethe yaseCanada.
