Ishishini leentambo kunye neentambo "lishishini lezinto ezisindayo nezikhaphukhaphu", kwaye iindleko zezinto zimalunga ne-65% ukuya kwi-85% yexabiso lemveliso. Ke ngoko, ukukhethwa kwezinto ezinentsebenzo efanelekileyo kunye nomlinganiselo wexabiso ukuqinisekisa umgangatho wezinto ezingena kumzi-mveliso yenye yeendlela ezibalulekileyo zokunciphisa iindleko zemveliso kunye nokuphucula ukukhuphisana kwamashishini.
Xa kukho ingxaki ngezinto eziluhlaza zentambo, intambo ngokuqinisekileyo iya kuba nengxaki, njengomxholo wobhedu kwixabiso lobhedu, ukuba iphantsi kakhulu, kufuneka ilungise inkqubo, kungenjalo iya kuvelisa iimveliso ezingafanelekiyo kwaye ibangele ilahleko. Ke namhlanje, singajonga nezo "zinto zimnyama" zentambo kunye nezinto eziluhlaza zentambo:
1. Intonga yobhedu: yenziwe ngobhedu olusetyenzisiweyo, ukutshintsha kombala we-oxidation yomphezulu, uxinzelelo alwanelanga, alungqukuva, njl.njl.
2. Iplastiki yePVC: ukungcola, ukuncipha kobunzima kubushushu obungafanelekanga, umaleko we-extrusion unemingxuma, kunzima ukuwubumba ngeplastiki, umbala awuchanekanga.
3. Izixhobo zokukhusela i-XLPE: ixesha lokuthintela ukutshisa lifutshane, kulula ukulidibanisa kwangoko, njalo njalo.
4. Izinto zokudibanisa i-Silane: ubushushu bokukhupha abukho lawuleki kakuhle, ulwandiso lobushushu alukho semgangathweni, uburhabaxa bomphezulu, njl.njl.
5. Iteyiphu yobhedu: ubukhulu obungalinganiyo, ukutshintsha kombala we-oxidation, ukuxinana okwaneleyo, ukuqhekeka, ukuthamba, ukuqina, intloko emfutshane, unxibelelwano olubi, ifilimu yopende okanye umaleko we-zinc ucinyiwe, njl.njl.
6. Ucingo lwentsimbi: ububanzi bangaphandle bukhulu kakhulu, umaleko we-zinc awusebenzi, i-galvanized ayanelanga, intloko imfutshane, uxinzelelo alwanelanga, njl.
7. Intambo yokuzalisa i-PP: izinto ezingasebenzi kakuhle, ububanzi obungalinganiyo, uqhagamshelo olubi njalo njalo.
8. Umcu wokuzalisa we-PE: uqinile, kulula ukuwuqhekeza, ukugoba akulingani.
9. Iteyiphu yelaphu engalukwanga: ubukhulu bokwenyani beempahla abuyonguqulelo, uxinzelelo alwanelanga, kwaye ububanzi abulingani.
10. Iteyiphu yePVC: ityebile, ayinelanga ukuxinana, intloko emfutshane, ubukhulu obungalinganiyo, njl.njl.
11. Iteyiphu ye-mica erhabaxa: ukuhluma, ukuxinana akwanelanga, idiski yebhanti enamathelayo, njl.njl.
12. Intambo yoboya belitye engena-alkali: ubukhulu obungalinganiyo, ukuxinana okwaneleyo, amalungu amaninzi, umgubo olula ukuwa njalo njalo.
13. Intambo yefayibha yeglasi: ityebile, inomtsalane, uxinano lokuluka luncinci, imicu exutyiweyo yendalo, kulula ukuyikrazula njalo njalo.
14.Itheyiphu ethintela ilangatye engenamsi esezantsi: kulula ukuphula, iteyiphu imibimbi, umzobo, into ethintela ilangabi elibi, umsi njalo njalo.
15. Isigqubuthelo esinciphayo ngobushushu: iinkcukacha kunye nobukhulu akuvumelekanga, inkumbulo embi yezinto, ukuncipha kokutsha ixesha elide, amandla aphantsi, njl.njl.
Ngoko ke, abenzi beengcingo kunye neentambo kufuneka baqaphele ngakumbi xa bekhethaizinto zokwenziwa kwentamboOkokuqala, kufuneka kwenziwe uvavanyo olupheleleyo lokusebenza kwesampulu ukuqinisekisa ukuba izinto eziluhlaza zinokuhlangabezana neemfuno zobugcisa kunye nemigangatho yomgangatho wemveliso. Okwesibini, nikela ingqalelo esondeleyo kwiparameter nganye yemveliso ukuqinisekisa ukuba iyahlangabezana neemfuno zoyilo kunye neemfuno zesicelo esisebenzayo. Ukongeza, kuyimfuneko ukwenza uphando olupheleleyo lwababoneleli bezinto eziluhlaza zentambo kunye neentambo, kubandakanya ukuphonononga iziqinisekiso zabo kunye nokuthembeka, ukuvavanya amandla abo emveliso kunye nenqanaba lobugcisa ukuqinisekisa ukuba umgangatho wezinto eziluhlaza ezithengiweyo uthembekile kwaye ukusebenza kuzinzile. Kuphela ngolawulo olungqongqo apho sinokuqinisekisa umgangatho kunye nokhuseleko lweemveliso zentambo kunye neentambo.
