1. Amandla nokumelana nokugqoka: Amandla nokumelana nokugqoka kwezindwangu kungenye yezici zazo eziyisisekelo. Ngokuvamile, ukuphakama kwamandla okuqinile emicu, ayanda amandla endwangu. Ngaphezu kwalokho, ngenxa yamandla okusebenzelana phakathi kwamafayibha, izindwangu zikwazi ukumelana nokuguga futhi zingamelana-nezingxabano nokuguga kwesikhathi eside.
2. Ukuphefumula: Ukuphefumula kwendwangu kubhekisela ekungeneni kwayo emoyeni nasemoyeni wamanzi. Izindwangu ezikwazi ukuphefumula kahle zingavumela isikhumba ukuba siphefumule futhi sijuluke ngokwanele, kunciphise ukujuluka kanye nokukhiqizwa kwephunga. Izindwangu ezinokuphefumula okuhle ngokuvamile zinokunethezeka okuhle nokuzivumelanisa nezimo.
3. Ukufakwa kwe-thermal: Ukusebenza kokufakwa kwe-thermal kwendwangu kubhekisela emandleni ayo okugcina ukushisa. Izindwangu zingavimbela ukulahlekelwa ukushisa ngokugcina isendlalelo somoya futhi zinikeze imfudumalo ezindaweni ezibandayo. Izindwangu ezinezakhiwo ezinhle zokuvikela zivame ukuba nokufakwa okuhle nokunethezeka.
4. Ukumunca umswakama: Ukusebenza kokumunca umswakama kwendwangu kubhekisela emandleni ayo okumunca umswakama. Izindwangu ezimunca kahle umswakama zingashesha ukumunca umjuluko kanye nomswakama ebusweni bomzimba, zigcine isikhumba somile futhi sinethezekile ngaso sonke isikhathi. Ngaphezu kwalokho, izindwangu ezinomswakama omuhle zinganciphisa ukukhiqizwa kukagesi omile, okuzuzisa esikhumbeni nasempilweni.
5. Ukumelana namakhemikhali: Ukumelana kwamakhemikhali kwezindwangu kubhekisela emandleni azo okumelana nezinto zamakhemikhali. Izindwangu ezinokumelana okuhle namakhemikhali zingaba nokuzinza okuhle nokumelana nezindawo zamakhemikhali ezihlukene, futhi azigqwali kalula futhi zilinyazwa izinto zamakhemikhali.
