Ukukhetha izinto zokufulela izakhiwo zemfuyo kubandakanya okungakumbi kunokuthelekisa amaxabiso okuthenga. Inkqubo yokufulela ichaphazela ngqo iimfuno zogcino, imeko yangaphakathi, iindleko zokusebenza, kunye{1}}nenzuzo yexesha elide.
Kangangamashumi eminyaka, iintsimbi ezifakwe igalvanized ziye zalawula ulwakhiwo lwezolimo. Nangona kunjalo, abatyali-mali abaninzi bemfuyo kulo lonke elaseLatin America ngoku bayaqwalaselaASA PVC uphahla amaphephanjengenye indlela.
Ukunyangwa koMhlwa
Obona buthathaka bukhulu bophahla lwentsimbi yesinyithi kwindawo yezolimo kukudleka.
Izibonelelo zemfuyo zivelisa:
- Ukufuma
- Iigesi ze-ammonia
- Iiasidi ze-Organic
- Ukucoca imichiza
Ezi zinto zikhawuleza ukuwohloka kwesinyithi.
Umrhwaphilizo udla ngokuqala ngo:
- Izibophelelo
- Uphahla luyawelana
- Sika imiphetho
- Iindawo ezisesichengeni sokujiya
Izinto zokuphahla ze-PVC zixhatshazwa yikhemikhali kwezi meko kwaye musa ukugqwala.
Ukusebenza kweThermal
Ulawulo lobushushu lubalulekile kwimveliso yemfuyo.
Uphahla lwesinyithi ludlulisela ubushushu ngokukhawuleza kwizakhiwo, ukwandisa imfuno yokungena komoya kunye neendleko zokupholisa.
Uphahla lwe-ASA PVCngokubanzi yenza ngcono ekunciphiseni ukuhanjiswa kobushushu, inceda ukugcina indawo engaphakathi ezinzileyo.
Oku kubaluleke kakhulu kwi:
- Izindlu zeenkukhu
- Iifama zeehagu
- Izibonelelo zobisi
UkuNcitshiswa kwengxolo
Ingxolo yemvula ihlala ingahoywa ngexesha locwangciso lweprojekthi.
Imvula enkulu kuphahla lwentsimbi yenza amanqanaba abalulekileyo engxolo anokuthi achaphazele abasebenzi kunye nezilwanyana.
Izinto zokuphahla zePVC zibonelela ngeempawu ezingcono zokugquma isandi, ziphucula intuthuzelo ngaphakathi kwezibonelelo zolimo.
Ukufakela kunye noLondolozo lweZakhiwo
Iinkqubo zokuphahla zePVC zikhaphukhaphu kwaye kulula ukuzithutha nokuzifaka.
Izibonelelo ziquka:
- Iishedyuli zokwakha ezikhawulezayo
- Iindleko zabasebenzi eziphantsi
- Iimfuno ezincitshisiweyo zesakhiwo
Ezi nzuzo zibaluleka kakhulu kwiiprojekthi{0} ezinkulu zezolimo.
IiMfuno zoLondolozo
Iindleko zokulungisa ziqokelelana kubomi besakhiwo.
Uphahla lwentsimbi lunokufuna:
- Unyango lomhlwa
- Ukutshintshwa kweFastener
- Ukulungiswa komphezulu
- Ukutshintshwa kophahla oluyinxenye
Iisistim zePVC zokufulela zifuna ulungiso oluncinci kwaye zibe namava okuhexa okumbalwa{0}okusilela okunxulumeneyo.
Uthelekiso lweendleko zoBomi
Nangona uphahla lwePVC ngamanye amaxesha lunokuba neendleko eziphezulu zokuthenga, ixabiso lilonke lobunini lihlala lisezantsi kwisithuba seminyaka engama-20 yokusebenza.
Abatyali mali beprojekthi baya bephonononga ngakumbi:
- Iindleko zolondolozo
- Iindleko zokuphumla
- Imijikelo yokutshintshwa
- Iimfuno zabasebenzi
Kwizicelo ezininzi zezolimo, uqoqosho lwe-lifecycle luthandaIinkqubo zokuphahla zePVC.
Ukuqukumbela
Isigqibo sokuphahla akufanele sisekelwe kuphela kwixabiso lezinto eziphathekayo.
Kumaziko emfuyo asebenza ngokuqhubekayo amashumi eminyaka, ukuxhathisa ukudleka, ukucuthwa kokulondolozwa, kunye nokusebenza ngokushushu kudla ngokudala ixabiso elikhulu lemali kunokonga iindleko zokuqala.
Esi sesinye sezizathu zokuba uphahla lwe-ASA lwePVC luqhubeke nokufumana isabelo sentengiso kulo lonke icandelo lezolimo laseLatin America.
