UTony Radoszewski, umongameli wePlastiki yePipe Institute, uxoxa ngomxholo osetyenzisiweyo kumbhobho kunye nokuguqula iiphakheji kunye ne-60-day life shelf ibe yimveliso kunye ne-100 yeminyaka yenkonzo.
UTony Radoszewski ngumongameli wePlastics Pipe Institute-intlangano enkulu yorhwebo yaseMntla Melika emele onke amacandelo ombhobho weplastiki.
Kuninzi ukugqunywa ngokusetyenziswa kweeplastiki zasemva kwabathengi ekupakishweni, kodwa kukho enye imakethi yokurisayikilishwa okungaxoxwa ngayo ngokubanzi: umbhobho owenziwe ngemathiriyeli esetyenzisiweyo.
Khangela i-Q & A yam engezantsi kunye noTony Radoszewski, umongameli wePlastiki yePipe Institute, eDallas, TX, apho exubusha iiplastiki ezihlaziyiweyo kwizicelo zemibhobho;zisebenza njani izinto ezisetyenzisiweyo;kunye nohambo lwakhe oluya eWashington, DC njengenxalenye ye-2018 Plastics Fly-In.
Umbuzo: Uqale nini ukubona amalungu ePPI eqala ukusebenzisa iiplastiki ezisetyenziswe ngokutsha?Zeziphi ezinye zezicelo zemibhobho?
A: Yikholwa okanye hayi, ishishini lombhobho weplastiki elithathiweyo lisebenzise i-HDPE ehlaziyiweyo yabathengi amashumi eminyaka.Ithayile yokuhambisa amanzi ezolimo, esetyenziselwa ukususa amanzi kumhlaba wefama ukuphucula imveliso yezityalo, isebenzise iibhotile zobisi ezisetyenzisiweyo kunye neebhotile zokucoca ezibuyela emva kwiminyaka yoo-1980.Ukusetyenziswa kwemibhobho, imathiriyeli ehlaziyiweyo yasemva komthengi inokusetyenziswa kuphela kwizicelo zokuqukuqela komxhuzulane.Oko kukuthi, umbhobho ongengowoxinzelelo ngenxa yamatyala endalo kunye nesidingo sokuqesha iireyini eziye zavavanywa ngokucokisekileyo kwaye zavavanyelwa izicelo zoxinzelelo.Ngoko ke, oko kuthetha ukukhupha amanzi amdaka, umbhobho we-culvert, umjelo wokuhambisa amanzi amdaka kunye nogcino/uvalelo olungaphantsi komhlaba.Kwakhona, i-conduit engaphantsi komhlaba inokwenzeka.
A: Ngokokwazi kwam, zonke izicelo zisebenzisa indibanisela zombini ezinyulu kunye neereyikhi ezisetyenzisiweyo.Kukho imiba emibini ebalulekileyo edlalwa apha.Eyokuqala kukugcina ingqibelelo yombhobho ogqityiweyo ukuze ikwazi ukwenza njengoko kuyilwe.Ngokuxhomekeke kumgangatho kunye nokwakheka komjelo wokuphinda usetyenziswe, ulungelelwaniso oluhlukeneyo lwentombi ukuya kumxholo ohlaziyiweyo luya kwenzeka.Omnye umba sisixa semathiriyeli eseyisetyenziswe ngokutsha ekhoyo emva komthengi.Ngelixa uninzi lwabathengi lufuna ukurisayikilisha iiplastiki, uninzi, ukuba ayilulo uninzi lwezixeko, alunazo iziseko zoncedo ezifunekayo ukuze ziqokelele, zihlele kwaye ziqhubekekise iimveliso zokuqala.Kwakhona, kukho izikhongozeli zokupakisha ezomeleleyo ezinomaleko amaninzi ngokuxhomekeke kwimveliso eziziphetheyo.Njengomzekelo, izithintelo ze-anti-oxidant usebenzisa i-EVOH zenza kube nzima ukurisayikilishwa.Eyona mathiriyeli ixhaphakileyo yokurisayikilishwa yi-HDPE kodwa ishishini lombhobho we-PVC nalo liyakwazi ukusebenzisa intlaka ehlaziyiweyo ngokunjalo.
A: Xa kucacisiwe ngokuhambelana nemigangatho yesizwe ye-AASHTO M294 okanye i-ASTM F2306, umbhobho we-HDPE owenziwe ngamalahle owenziwe ngomxholo ohlaziyiweyo okanye i-100 yepesenti ye-virgin content inomsebenzi olinganayo.Ngokutsho kweNCHRP yoPhando lweNgxelo 870, imibhobho ye-HDPE eyotyiweyo inokuveliswa ngempumelelo ngemathiriyeli esetyenzisiweyo ukukhawulelana neemfuno zobomi benkonzo efanayo yokusetyenziswa ngaphantsi kohola wendlela kunye nezicelo zikaloliwe njengoko imibhobho eyenziwe nge-resin enyulu ibonelele nge-Un-notched Constant Ligament Stress (UCLS) iimfuno ziyahlangatyezwa.Ngoko ke, imigangatho ye-AASHTO M294 kunye ne-ASTM F2306 yemibhobho ye-HDPE ye-corrugated yahlaziywa ngo-2018 ukuze ibonise isibonelelo se-virgin kunye / okanye i-recycled content resin (ibonelele ukuba iimfuno ze-UCLS ze-recycled resins zidibene).
A: Ngelizwi nje, ucelomngeni.Ngelixa uninzi lwabantu lufuna ukwenza okulungileyo kokusingqongileyo, kufuneka kubekho isiseko sokubuyisela inkunkuma endaweni ukuze kubekho unikezelo oluyimpumelelo lweeplastiki zasemva komthengi.Izixeko ezinengqokelela egqwesileyo kunye neenkqubo zokuhlela zenza kube lula kubantu ngokubanzi ukuba bazibandakanye kwiinkqubo zecurbside recycling.Oko kukuthi, okukhona uyenza lula ukuba umntu avele ahlule izinto ezinokuphinda zisetyenziswe kwizinto ezingaphinda zisetyenziswe, kokukhona uphezulu umlinganiselo wokuthatha inxaxheba.Umzekelo, apho ndihlala khona sine-95-gallon ye-HDPE container apho sibeka zonke izinto ezinokuphinda zisetyenziswe.Akukho mfuneko yokwahlula iglasi, iphepha, iiplastiki, ialuminiyam njalo njalo.Icholwa elunxwemeni kanye ngeveki kwaye amaxesha amaninzi uyabona ukuba izitya zigcwele.Thelekisa oku kumasipala ofuna imigqomo emininzi kudidi ngalunye lwemathiriyeli kwaye umnini-ndlu kufuneka ayihlisele kwiziko lokurisayikilisha.Kucace gca ukuba yeyiphi inkqubo eya kuba nezinga lokuthatha inxaxheba okukhulu.Umceli mngeni ziindleko zokwakha ezo ziseko zoncedo zokurisayikilisha nokuba ngubani oza kuzihlawulela.
Umbuzo: Ngaba unokuthetha malunga nokutyelela kwakho kwiCapitol Hill yePlastiki Industry Fly-In (Sept. 11-12, 2018)?Yaba njani impendulo?
IMPENDULO: Ishishini leplastiki licandelo lesithathu elikhulu lemveliso eMelika liqeshe abasebenzi abaphantse babe sisigidi kwiphondo ngalinye nakwisithili seCongress.Izinto eziphambili kushishino lwethu zimalunga nokhuseleko lwabasebenzi bethu;ukusetyenziswa ngokukhuselekileyo kweemveliso zethu;kunye nolawulo oluzinzileyo lwemathiriyeli, kwaye kunye siyaqhubeka sisebenza kulawulo olunoxanduva lokusingqongileyo kulo lonke ikhonkco lokubonelela ngeplastiki kunye nomjikelo wobomi.Sasiba ngaphezu kwe-135 iingcali zoshishino zeplastiki (kungekhona nje umbhobho) ukusuka kwilizwe lonke ukubiza i-Congressmen ye-120, iiSenators kunye nabasebenzi ukuba baxoxe ngemiba emine engundoqo ijongene noshishino namhlanje.Ngokubhekiselele kumaxabiso aziswayo, urhwebo lwasimahla luyinkxalabo enkulu kwishishini lethu ngokwembono yokungenisa nokuthumela ngaphandle.Ngaphezulu kwe-500,000 yemisebenzi yokuvelisa engazaliswanga namhlanje, ishishini leplastiki limi lilungele ukusebenza ngokubambisana neenkokeli kumanqanaba omanyano, urhulumente kunye nengingqi ukunceda ukufumana izisombululo zokuvala umsantsa wezakhono kubasebenzi banamhlanje nakwixesha elizayo ukuqeqesha abasebenzi abaqeqeshiweyo kuzo zonke izakhono. amanqanaba emisebenzi yokuvelisa.
Ngokunxulumene nombhobho weplastiki ngokukodwa, ukhuphiswano olufanelekileyo noluvulelekileyo lwezixhobo kufuneka lufuneke kuyo nayiphi na iprojekthi yeziseko ezingundoqo ezixhaswa ngemali ngurhulumente.Amagunya amaninzi asekuhlaleni aneenkcazo ezindala ezingavumeli umbhobho weplastiki ukuba ukhuphisane, ukudala "i-monopolies ebonakalayo" kunye nokunyusa iindleko.Ngexesha lezinto ezilinganiselweyo, ezifuna iiprojekthi ezichitha iidola zomdibaniso ukuvumela ukhuphiswano lunokuphinda kabini impembelelo entle yenkxaso yomanyano, ukugcina imali yabarhafi bendawo.
Kwaye okokugqibela, ukusetyenzwa kwakhona kunye nokuguqulwa kwamandla kubalulekile kwiinketho zokuphela kobomi kwizinto zeplastiki.Isizwe sijongene nemeko emandundu malunga nomthamo wokurisayikilishwa kunye neemarike zokuphela kwezinto ezisetyenzisiweyo.Iziseko ezingundoqo ezongezelelweyo ziyimfuneko ukuphucula ukusebenza kakuhle kokurisayikilishwa kwe-US kunye nokunyusa umthamo wezinto eziphinda zisetyenziswe e-US
Izikhundla zethu zamkelwe kakuhle kakhulu njengoko besichukumisa izinto ezibalulekileyo phantse kuye wonke umntu weli lizwe.Oko kukuthi iindleko, abasebenzi, iirhafu kunye nokusingqongileyo.Ukukwazi kwethu ukubonisa ukuba ishishini lemibhobho yeplastiki ngoku lisebenzisa i-25 yeepesenti yeebhotile ze-HDPE zasemva kwabathengi kwaye ukuzijika zibe ngumbhobho osetyenziswa kwiziseko ezingundoqo eziphantsi komhlaba wawuvula amehlo kuninzi lwabantu esidibene nabo.Sibonise indlela ishishini lethu elithatha ngayo imveliso eneshelufu yeentsuku ezingama-60 kwaye iyiguqulele kwimveliso enobomi benkonzo yeminyaka eyi-100.Le yinto wonke umntu onxulumene nayo kwaye wabonisa ngokucacileyo ukuba ishishini lombhobho weplastiki linokuba yinxalenye yesisombululo sokukhusela okusingqongileyo.
Iphepha le-synthetic elisekelwe kwi-polyethylene egcweleyo okanye ifilimu ye-polypropylene sele ikhona amashumi eminyaka ngaphandle kokubangela uchulumanco olukhulu-kude kube kutshanje.
Zonke izinto ziyalingana, i-PET iya kugqitha i-PBT ngoomatshini nangobushushu.Kodwa iprosesa kufuneka yomise izinto ngokufanelekileyo kwaye kufuneka iqonde ukubaluleka kweqondo lokushisa lokungunda ekufezekiseni iqondo le-crystallinity evumela ukuba izibonelelo zendalo zepolymer zifezekiswe.
X Enkosi ngokuthathela ingqalelo umrhumo kwiPlastiki Technology.Siyaxolisa kukubona uhamba, kodwa ukuba utshintsha ingqondo yakho, singathanda ukuba nawe njengomfundi.Cofa nje apha.
