Kwimeko yemizi-mveliso yanamhlanje, ukukhutshwa kombhobho weplastiki kuguqula amacandelo ahlukeneyo ngokunikezela ngezisombululo ezisebenzayo, ezingabizi kakhulu, neziguquguqukayo. Ukukwazi ukuvelisa imibhobho ngobukhulu obahlukeneyo kunye nezixhobo zenze i-extrusion yombhobho weplastiki ibe yinto ekhethwayo kwizicelo ezininzi. Kweli nqaku, siza kuphonononga ukusetyenziswa okuphezulu kombhobho weplastiki extrusion kunye nendlela abanokuzuza ngayo ishishini lakho.
Yintoni iPlastiki yoMbhobho wokuKhulisa?
Ukukhutshwa kombhobho weplastiki yinkqubo yokuvelisa apho izinto zeplastiki zinyibilika kwaye zenziwe zibe yimibhobho eqhubekayo. Le ndlela ivumela ukudala imibhobho kunye nemilinganiselo ehambelanayo kunye neempawu, okwenza ukuba ilungele uluhlu olubanzi lwezicelo. Ngokunyuka kwemfuno yezinto ezihlala ixesha elide kunye nezikhaphukhaphu, ukukhutshwa kombhobho weplastiki kukufumana ukutsaleka kumashishini amaninzi.
1. Ubonelelo lwaManzi kunye neeNkqubo zoSasazo
Esinye sezicelo ezibalaseleyo zokukhutshwa kombhobho weplastiki kukubonelela ngamanzi kunye neenkqubo zokuhambisa. Iipayipi zeplastiki, ngokukodwa ezo zenziwe nge-polyvinyl chloride (PVC) kunye ne-polyethylene (PE), zilungele ukuthutha amanzi okusela ngenxa yokumelana nokubola kunye nobunzima obuphantsi.
Ngokwengxelo ye-American Water Works Association, imibhobho yeplastiki ithatha malunga ne-70% yofakelo olutsha lonikezelo lwamanzi eMelika. Oku kunyuka kokwamkelwa komntwana kunokubalelwa kubomi babo obude, ukulula kofakelo, kunye nokunciphisa iindleko zokuyilungisa xa kuthelekiswa nezinto zemveli ezifana nentsimbi kunye nekhonkrithi.
2. Ulawulo lwamanzi amdaka kunye namanzi amdaka
Ukukhutshwa kombhobho weplastiki kudlala indima ebalulekileyo kugutyulo kunye nolawulo lwamanzi amdaka. Ukuqina kunye nokuxhathisa imichiza kwimibhobho yeplastiki kubenza bafaneleke ukuphatha ugutyulo, amanzi esiphango, kunye namanzi amdaka avela kwimizi-mveliso.
Ngokomzekelo, imibhobho ye-polyethylene ephezulu (i-HDPE) isetyenziswa ngokuqhelekileyo kwiinkqubo zogutyulo ngenxa yokukwazi ukumelana neemeko ezinzima kunye nokunciphisa ukungena kunye nokukhutshwa. Uphononongo olwenziwa yi-Water Environmental Federation lubonise ukuba imibhobho ye-HDPE ingahlala iminyaka engaphezu kwe-100 kwimibhobho yogutyulo, nto leyo enciphisa kakhulu imfuneko yokutshintshwa nokulungiswa.
3. Iinkqubo zokunkcenkceshela kwezoLimo
Icandelo lezolimo likwamkele ukukhutshwa kwemibhobho yeplastiki kwiinkqubo zokunkcenkceshela. Iinkqubo zokunkcenkceshela zokunkcenkceshela kunye nezixhobo zokunkcenkceshela zisebenzisa imibhobho yeplastiki ukusasaza amanzi ngokufanelekileyo, inciphisa inkcitho kunye nokuphucula izivuno zezityalo.
Ingxelo yeFood and Agriculture Organisation (FAO) ibonisa ukuba ukusetyenziswa konkcenkceshelo ngedrip kunganyusa ukusebenza kwamanzi nge30-50% xa kuthelekiswa neendlela zamandulo. Ubume obukhaphukhaphu bemibhobho yeplastiki yenza kube lula ukuyifaka kunye nokuthutha, ukunyusa ngakumbi isibheno sabo kwizicelo zezolimo.
4. Unxibelelwano kunye neConduit yoMbane
I-extrusion yombhobho wePlastiki ibalulekile kwii-telecommunications kunye namashishini ombane ekukhuselweni kwentambo kunye nokufakwa. Imibhobho ye-conduit eyenziwe kwi-PVC okanye i-HDPE isetyenziselwa ukukhusela iintambo zombane emonakalweni womzimba kunye nemiba yokusingqongileyo.
Ngokutsho kweNational Electrical Contractors Association, ukusebenzisa i-plastic conduit kunokunciphisa ixesha lokufakela kunye neendleko zabasebenzi ngenxa yeempawu zayo ezilula kunye nokulula ukuphatha. Ngaphaya koko, imibhobho yeplastiki iyamelana nokubola nokufuma, iqinisekisa ubomi obude beenkqubo zombane ezizikhuselayo.
5. Ukwakha kunye noKwakha
Kwishishini lokwakha kunye nelokwakha, ukukhutshwa kombhobho weplastiki kusetyenziselwa izicelo ezahlukeneyo, kubandakanywa neenkqubo zokuhambisa amanzi, imibhobho yamanzi, kunye ne-HVAC (i-heating, i-ventilation, kunye ne-air conditioning). Ukuguquguquka kwemibhobho yeplastiki kuvumela ukudityaniswa ngokungenamthungo kulwakhiwo olutsha kunye nokulungiswa.
Uphando olwenziwe yi-International Association of Plumbing and Mechanical Officials (IAPMO) lufumene ukuba i-60% yeengcali zemibhobho zikhetha iipayipi zeplastiki zokufakelwa kwazo ngenxa yeendleko-zokusebenza kunye nokuthembeka. Ubume obukhaphukhaphu bemibhobho yeplastiki yenza lula uthutho kunye nofakelo, okukhokelela kumaxesha akhawulezayo okugqitywa kweprojekthi.
I-Case Study: Ukuphunyezwa ngokuyimpumelelo kuPhuhliso lweDolophu
Uphononongo oluphawulekayo lwempembelelo yokukhutshwa kwemibhobho yeplastiki inokubonwa kwiprojekthi yophuhliso lwedolophu yesixeko esikhulu. Umasipala uye wakhetha imibhobho yeHDPE kwiinkqubo zabo ezintsha zokuhambisa amanzi kunye nogutyulo.
Ngokusebenzisa ubuchwepheshe bemibhobho yeplastiki, isixeko sabika ukuncitshiswa kwe-30% kwiindleko zofakelo kunye nokwehla okukhulu kwiziganeko zokuvuza kwamanzi. Ukongeza, ubomi obude bemibhobho ye-HDPE buye banciphisa imfuno yokulungiswa kwexesha elizayo, ekugqibeleni kuxhamle uhlahlo lwabiwo-mali lwesixeko kunye nokuphucula umgangatho wobomi kubahlali.
Izicelo ezahlukeneyo zokukhutshwa kombhobho weplastiki ziguqula amashishini ngokubonelela ngezisombululo ezisebenzayo, ezihlala ixesha elide, kunye neendleko. Ukusuka kwiinkqubo zokubonelela ngamanzi ukuya kwezolimo kunye nezonxibelelwano, iinzuzo zokusebenzisa imibhobho yeplastiki ziyabonakala.
Njengoko imizi-mveliso iqhubeka nokuvela, ukuqonda ukusetyenziswa kwemibhobho yeplastiki extrusion kunokuxhobisa amashishini ukuba enze izigqibo ezinolwazi eziphakamisa ukusebenza kakuhle kunye nokuzinza. Ngokukhetha imibhobho yeplastiki, iinkampani azigcini nje ngokutyala imali kwimveliso ethembekileyo kodwa zikwafaka isandla kwikamva eliluhlaza, elinempumelelo ngakumbi. Nokuba ubandakanyeka kulwakhiwo, kwezolimo, okanye kwiinkonzo zikamasipala, ukwamnkela umbhobho weplastiki extrusion inokuba linyathelo lakho elilandelayo lobuchule.
