Tony Radoszewski, pulezidenti wa Plastics Pipe Institute, akukambirana zomwe zasinthidwanso mu chitoliro ndikusintha mapaketi okhala ndi alumali wamasiku 60 kukhala zinthu zokhala ndi moyo wazaka 100.
Tony Radoszewski ndi purezidenti wa Plastics Pipe Institute - bungwe lalikulu lazamalonda ku North America lomwe likuyimira magawo onse amakampani opanga mapaipi apulasitiki.
Pali zambiri zokhudzana ndi kugwiritsa ntchito mapulasitiki omwe abwera pambuyo pa ogula pakuyika, koma pali msika wina wobwezeretsanso womwe sunakambidwe kwambiri: chitoliro chopangidwa ndi zida zobwezerezedwanso.
Onani pansipa Q&A yanga ndi Tony Radoszewski, purezidenti wa Plastics Pipe Institute, Dallas, TX, komwe amakambilana za mapulasitiki obwezerezedwanso mu ntchito zamapaipi;momwe zida zobwezerezedwanso zimagwirira ntchito;ndi ulendo wake wopita ku Washington, DC monga gawo la 2018 Plastics Fly-In.
Q: Munayamba liti kuwona mamembala a PPI akuyamba kugwiritsa ntchito mapulasitiki opangidwanso ndi ogula?Kodi zina mwazogwiritsa ntchito mapaipi ndi ziti?
A: Khulupirirani kapena ayi, makampani opanga mapaipi apulasitiki akhala akugwiritsa ntchito HDPE yosinthidwanso kwazaka zambiri.Tile ya Agricultural drainage, yomwe imagwiritsidwa ntchito kutulutsa madzi m'mafamu kuti apititse patsogolo ulimi wa mbewu, agwiritsa ntchito mabotolo a mkaka obwezerezedwanso ndi mabotolo otsukira kuyambira m'ma 1980.Pakugwiritsa ntchito mapaipi, zinthu zobwezerezedwanso pambuyo pa ogula zitha kugwiritsidwa ntchito pamachitidwe amphamvu yokoka.Ndiko kuti, mapaipi osakakamiza chifukwa cha mangawa obadwa nawo komanso kufunikira kogwiritsa ntchito ma resin omwe adawunikidwa bwino ndikuyesedwa kuti agwiritse ntchito.Chifukwa chake, izi zikutanthauza ngalande ya ag, chitoliro cha culvert, ngalande za turf ndi kusungira pansi pansi / kutsekera.Komanso, njira yapansi panthaka ndiyothekanso.
A: Monga ndikudziwira, ntchito zonse zimagwiritsa ntchito ma resin omwe sanamwalire komanso opangidwanso.Pali zinthu ziwiri zazikulu zomwe zikuseweredwa apa.Choyamba ndikusunga umphumphu wa chitoliro chomalizidwa kuti chizigwira ntchito monga momwe chinapangidwira.Kutengera ndi mtundu ndi mapangidwe a recycle mtsinje, ma ratios osiyanasiyana a namwali kuti zobwezerezedwanso zili zidzachitika.Nkhani ina ndi kuchuluka kwa zinthu zobwezeredwa pambuyo pa ogula zomwe zilipo.Ngakhale ogula ambiri akufuna kukonzanso mapulasitiki, mizinda yambiri, ngati si yambiri, ilibe zida zofunikira kuti atolere, kusanja ndi kukonza zinthu zoyambirira.Komanso, pali zotengera zomangirira zolimba zomwe zimakhala ndi mitundu ingapo kutengera zomwe ali nazo.Mwachitsanzo, zotchinga za anti-oxidant pogwiritsa ntchito EVOH zimapangitsa kuti zikhale zovuta kukonzanso.Zomwe zimagwiritsidwa ntchito kwambiri pakubwezeretsanso ndi HDPE koma makampani opanga mapaipi a PVC amathanso kugwiritsa ntchito utomoni wobwezerezedwanso.
A: Mukatchulidwa motsatira mfundo za dziko la AASHTO M294 kapena ASTM F2306, chitoliro cha HDPE cha malata chopangidwa ndi zinthu zobwezerezedwanso kapena 100 peresenti ya zinthu zomwe sizinachitikepo ndizofanana.Malinga ndi NCHRP Research Report 870, mapaipi opangidwa ndi malata a HDPE amatha kupangidwa bwino ndi zida zobwezerezedwanso kuti akwaniritse zofunikira za moyo wautumiki kuti agwiritse ntchito pansi pa msewu waukulu ndi njanji monga mapaipi opangidwa ndi utomoni wa namwali amapereka magwiridwe antchito a Un-notched Constant Ligament Stress (UCLS) zofunikira zikukwaniritsidwa.Chifukwa chake, miyezo ya AASHTO M294 ndi ASTM F2306 ya mapaipi amalata a HDPE adasinthidwa mu 2018 kuti awonetsere chilolezo cha namwali komanso/kapena zobwezerezedwanso za utomoni (ngati zofunikira za UCLS zama resin obwezerezedwanso zikukwaniritsidwa).
A: Mwa mawu amodzi, kutsutsa.Ngakhale kuti aliyense amafuna kuchita zomwe zili zoyenera pazachilengedwe, payenera kukhala malo obwezeretsa zinyalala kuti azitha kupeza bwino mapulasitiki ogula pambuyo pake.Mizinda yomwe ili ndi machitidwe apamwamba osonkhanitsa ndi kusanja amapangitsa kuti zikhale zosavuta kuti anthu ambiri azichita nawo mapulogalamu obwezeretsanso.Izi zikutanthauza kuti, mukamasavuta kuti wina angolekanitsa zobwezeretsedwanso kuchokera ku zosagwiritsidwanso ntchito, m'pamenenso anthu otenga nawo mbali amakwera.Mwachitsanzo, komwe ndimakhala tili ndi chidebe cha HDPE cha galoni 95 momwe timayikamo zonse zobwezeretsedwa.Palibe chifukwa cholekanitsa galasi, mapepala, mapulasitiki, aluminiyamu ndi zina zotero.Amatengedwa pamphepete kamodzi pa sabata ndipo nthawi zambiri mumatha kuona kuti zotengerazo zadzaza.Fananizani izi ndi tauni yomwe imafuna nkhokwe zingapo pamtundu uliwonse wazinthu ndipo mwininyumba amayenera kuzitengera kumalo obwezeretsanso.Ndizodziwikiratu kuti ndi dongosolo liti lomwe likhala ndi chiwopsezo chachikulu chotenga nawo mbali.Chovuta ndi mtengo womanga malo obwezeretsanso ndi omwe adzalipirire.
Q: Kodi mungalankhule za ulendo wanu ku Capitol Hill kwa Plastics Industry Fly-In (Sept. 11-12, 2018)?Kodi yankho linali lotani?
A: Makampani opanga mapulasitiki ndi gawo lachitatu lalikulu kwambiri ku United States lolemba anthu ogwira ntchito pafupifupi miliyoni imodzi m'boma lililonse ndi chigawo chilichonse.Zofunika kwambiri pamakampani athu zimakhudza chitetezo cha ogwira ntchito;kugwiritsa ntchito bwino zinthu zathu;ndi kasamalidwe kokhazikika kwa zida, ndipo palimodzi tikupitilizabe kugwira ntchito yosamalira zachilengedwe munthawi yonseyi yoperekera mapulasitiki ndi moyo wonse.Tidakhala ndi akatswiri opitilira 135 amakampani apulasitiki (osati chitoliro chokha) ochokera mdziko lonselo akuitanira ma Congressmen 120, maseneta ndi ogwira ntchito kuti akambirane zinthu zinayi zofunika zomwe makampani akukumana nazo lero.Potengera mitengo yamitengo yomwe ikuyambika, malonda aulere ndiwodetsa nkhawa kwambiri pamakampani athu potengera kutengera ndi kutumiza kunja.Ndi ntchito zopitilira 500,000 zomwe sizikukwaniritsidwa masiku ano, makampani opanga mapulasitiki ali okonzeka kugwira ntchito mogwirizana ndi atsogoleri a federal, maboma ndi amderali kuti athandizire kupeza mayankho oletsa kusiyana kwa luso la ogwira ntchito masiku ano komanso amtsogolo kuti aphunzitse ogwira ntchito oyenerera pa luso lililonse. mlingo wa ntchito zopanga.
Zokhudzana ndi chitoliro cha pulasitiki makamaka, mpikisano wachilungamo komanso womasuka wa zida uyenera kufunidwa pantchito iliyonse yothandizidwa ndi boma.Madera ambiri am'derali ali ndi machitidwe akale omwe salola kuti chitoliro cha pulasitiki chipikisane, kupanga "olamulira okhazikika" ndikukweza mtengo.Munthawi yazinthu zochepa, kufunafuna mapulojekiti omwe amawononga madola a feduro kulola mpikisano kungathe kuwirikiza kawiri zotsatira zabwino za thandizo la federal, kupulumutsa ndalama za okhometsa msonkho.
Ndipo potsiriza, kubwezeretsanso ndi kutembenuza mphamvu ndizofunikira kumapeto kwa moyo wa zipangizo zapulasitiki.Dzikoli likuyang'anizana ndi vuto lalikulu pankhani yobwezeretsanso mphamvu komanso misika yotsiriza ya zinthu zobwezerezedwanso.Zomangamanga zowonjezera ndizofunikira kuti ntchito yobwezeretsanso ntchito yaku US ichuluke ndikuwonjezera kuchuluka kwa zinthu zomwe zikugwiritsidwanso ntchito ku US
Maudindo athu adalandiridwa bwino kwambiri pomwe tidakhudza zinthu zomwe zili zofunika pafupifupi aliyense mdziko muno.Izi ndizo ndalama, ntchito, misonkho ndi chilengedwe.Kukhoza kwathu kuwonetsa kuti makampani opanga mapaipi apulasitiki akugwiritsa ntchito 25 peresenti ya mabotolo a HDPE omwe amagula pambuyo pa ogula ndikusandutsa chitoliro chomwe chimagwiritsidwa ntchito m'mapangidwe apansi panthaka chinali chotsegula maso kwa anthu ambiri omwe tinakumana nawo.Tidawonetsa momwe makampani athu amatengera chinthu chomwe chimakhala ndi nthawi yashelufu yamasiku 60 ndikuchisintha kukhala chinthu chomwe chimakhala ndi moyo wazaka 100.Ichi ndi chinthu chomwe aliyense akugwirizana nacho ndikuwonetseratu kuti makampani opanga mapaipi apulasitiki angakhale gawo la njira yothetsera chilengedwe.
Mapepala opangidwa ndi polyethylene kapena polypropylene yodzazidwa ndi filimu yakhalapo kwa zaka zambiri popanda kubweretsa chisangalalo chachikulu - mpaka posachedwapa.
Zinthu zonse kukhala zofanana, PET ipambana PBT mwamakina komanso kutentha.Koma purosesa iyenera kuuma zinthuzo moyenera ndipo iyenera kumvetsetsa kufunikira kwa kutentha kwa nkhungu kukwaniritsa digiri ya crystallinity yomwe imalola kuti ubwino wachilengedwe wa polima uchitike.
X Zikomo poganizira zolembetsa ku Plastics Technology.Pepani kukuwonani mukupita, koma ngati mutasintha malingaliro anu, tikadakondabe kukhala nanu ngati owerenga.Ingodinani apa.
