① Bheka ikhwalithi
Ohlotsheni lwemakethe yemishini eminingi ye-UV, abathengi kulula ukukhangwa i-halo yohlu lomkhiqizi kanye nomphumela wokukhangisa, ngoba umkhiqizo nekhwalithi akuhambisani ngokuphelele, okwenza abakhiqizi abaningi bokukhangisa bawele ekuthengeni ukungaqondi kahle.Kubakhiqizi, ngokuya ngezidingo zabo zebhizinisi, kusukela kukhwalithi yokuphuma kwekhasimende kanye nenani le-oda ukuze bahlole imodeli edingekayo, kuyilapho bephenya inethiwekhi yomkhiqizi ngemva kokuthengisa namandla esevisi.Ikhwalithi yokuphuma yomshini we-UV ihlanganisa izinkomba eziningana ezifana nobubanzi obubanzi, ukunemba nesivinini.Yiqiniso, akuyona inombolo yenkomba ephakeme, engcono, kodwa futhi kudingeka ucabangele ukusebenza kwezindleko kanye nemvelo yokusebenzisa.
② Bheka ukusebenza kwezindleko
Intengo kufanele ifane nevelu ukuze ibe enengqondo, ngakho awukwazi ukumane ugqolozele inani lentengo, ugxile ezinzuzweni, ezifana nokusebenza kahle kokukhiqiza, umjikelezo wokubuyisela, amanani okuthengekayo, njll. Isici esinqumayo sokuthenga umshini we-UV akulutho. ngaphezu kwekhwalithi yokuphuma, ukusebenza kahle kokukhiqiza, isevisi yangemuva kokuthengisa, njll., ngoba uma usunobunikazi bomshini, noma yimuphi umehluko ohlelweni lokusebenzisa uwukutshalwa kwezimali okuqhubekayo.
