Ukukhethwa kwezinto eziphathekayo kwiikhabhinethi zokulawula kuchaphazela ngokuthe ngqo ukukhuselwa kwazo, ukuqina, kunye neemeko ezifanelekileyo. Zahlulwe ngokwezintlu zilandelayo:
1. Isinyithi
- Intsimbi engatyiwayo: I-Corrosion{1}}iyaxhathisa kunye ne-oxidation{2}}iyaxhathisa, ifanele iindawo ezifumileyo, imizi-mveliso yeekhemikhali, okanye imveliso yokutya, kodwa ngexabiso eliphezulu.
- Intsimbi yeCarbon: Ezoqoqosho kunye nokusebenza, kunye namandla aphezulu omatshini, ifuna unyango olungaphezulu (njengokutshiza ngeplastiki) ukukhusela i-rust kwaye isetyenziswa ngokuqhelekileyo kwiindawo zoshishino.
- I-aluminiyam ialloyi: Ikhaphukhaphu kwaye inobubushushu obulungileyo, ilungele izixhobo eziphathwayo okanye-ubushushu obuphezulu, kodwa inika ukhuseleko oluncinci.
2. Iiplastiki zobunjineli
- I-ABS/ipolycarbonate: Ukugquma okugqwesileyo, ukhaphukhaphu, kunye nokumelana neekhemikhali, ezifanelekileyo kwiilabhoratri, amaziko onyango, okanye ukusetyenziswa kwangaphandle (okufuna ukhuseleko lwe-UV), kodwa ngokuxhathisa impembelelo encinci.
3. Iimathiriyeli ezihlanganisiweyo
- Enje nge-fiberglass eyomeleziweyo yeplastiki (FRP), zibonelela ngokuxhathisa ukubola kunye namandla omatshini, kodwa zibiza kakhulu kwaye zihlala zisetyenziswa kwindawo ezikhethekileyo (ezifana neenqanawa kunye neekhemikhali zepetroli).
Iinqobo zoKhetho:
- Okusingqongileyo: Ukumelana nomhlwa kuyafuneka kusetyenziso lwangaphandle (khetha intsimbi engatyiwa/i-FRP); Ukutshatyalaliswa kobushushu kuyafuneka{1}}kwimekobume zobushushu obuphezulu (khetha ingxubevange yealuminiyam).
- Umgangatho woKhuseleko: Iikhabhathi zentsimbi zicetyiswa kwi-IP54 nangaphezulu, ngelixa iikhabhathi zeplastiki ezitywiniweyo ziyindlela yokukhetha i-IP65. Iindleko: Intsimbi yeCarbon inika elona xabiso lilungileyo lemali, ngelixa intsimbi engatyiwa kunye nemathiriyeli ehlanganisiweyo ifanelekile-ukuhlala ixesha elide.
Ngaphaya koko, indlela yokuxhoma (udonga{0}}olunyusiweyo, umgangatho{1}}omileyo) kunye neemfuno zokhuselo lombane (umzekelo, iikhabhathi zentsimbi zinokukhusela uphazamiseko) nazo kufuneka ziqwalaselwe.
