Umzi-mveliso weSine
Umgangatho kuphela kwekhrayitheriya yemveliso.Isimo sengqondo esingqongqo nesikhuselekileyo kufuneka sisetyenziswe kuzo zonke iinkalo zemveliso yemveliso.
Iindlela Zokuhlola
Iindlela zovavanyo zokuxhathisa ukothuka kwe-thermal kunye nokuqina kwezikhongozeli zeglasi;Indlela yokuvavanya i-GB/T 4548 kunye nokuhlelwa kokumelana nokhukuliseko lwamanzi kwindawo yangaphakathi yesitya seglasi;Imida evumelekileyo yelothe, i-cadmium, i-arsenic kunye ne-antimony yokuchithwa kwiibhotile zeglasi;3.1 umgangatho wemigangatho yeebhotile zeglasi
Uvavanyo lwamandla
Ibhotile ejikelezileyo iya kwenziwa ngokuhambelana nemimiselo ye-GB / T 6552. Khetha inxalenye ebuthathaka kakhulu okanye uqhagamshelwano lomzimba webhotile ngempembelelo.Uvavanyo lodidi lunokuqhutywa ngokulinganisa ukungqubana kwemveliso okanye ubhaqo kumatshini.
Ukujonga iSampuli
Okokuqala, bala inani leephakheji ezikhutshwe ngokwe-5% yenani elipheleleyo leepakethe kule bhetshi yempahla: isinye kwisithathu senani elifunekayo leepakethe zikhethwe ngokungenamkhethe ukusuka ngaphambili, phakathi nangasemva kwisithuthi ngasinye, kunye ne-30% - I-50% yeepakethe zikhethwe ngokungenamkhethe kwiphakheji nganye yokuhlolwa kwenkangeleko.
Kutheni sisi?
Isimo sengqondo sokuvelisa ngokungqongqo kunye noxanduva, inkqubo yokuvelisa esebenzayo.Lawula umgangatho webhotile ngokwemaleko ukuqinisekisa ukuba ibhotile iqinile kwaye iqinile.
