Tony Radoszewski, purezidhendi wePlastiki Pipe Institute, anokurukura zvakadzokororwa mupombi uye kushandura mapakeji ane mazuva makumi matanhatu ehupenyu hwesherufu kuita zvigadzirwa zvine makore zana ehupenyu hwesevhisi.
Tony Radoszewski ndiye purezidhendi wePlastiki Pipe Institute-iyo huru North American trade association inomiririra zvikamu zvese zveindasitiri yepombi yepurasitiki.
Pane zvakawanda zvekuvhara pakushandiswa kwemapurasitiki ekupedzisira-mutengi mukurongedza, asi pane imwe misika yekudzokorodza isingataurwe zvakanyanya: pombi inogadzirwa nezvinhu zvakadzokororwa.
Tarisa pazasi Q&A yangu naTony Radoszewski, purezidhendi wePlastiki Pipe Institute, Dallas, TX, kwaanokurukura mapurasitiki akadzokororwa mumapombi epombi;mashandire anoita zvinhu zvakadzokororwa;uye rwendo rwake kuenda kuWashington, DC sechikamu che2018 Plastics Fly-In.
Mubvunzo: Wakatanga rini kuona nhengo dzePPI dzichitanga kushandisa mapurasitiki akadzokororwa mushure mevatengi?Ndeapi mamwe emapombi ekushandisa?
A: Zvitende kana kwete, iyo corrugated yepurasitiki pombi indasitiri yanga ichishandisa post-vatengi yakadzokororwa HDPE kwemakumi emakore.Agricultural drain tile, iyo inoshandiswa kufambisa mvura kubva muminda yepurazi kuti ivandudze kurima zvirimwa, yashandisa mabhodhoro emukaka akadzokororwa nemabhodhoro ekugezesa achidzokera kumashure kusvika kuma1980s.Pamashandisirwo epombi, post-mutengi yakadzokororwa zvinhu zvinogona kunyatso shandiswa mugiravhiti yekuyerera maapplication.Kureva kuti, isiri-kudzvanywa pombi nekuda kwezvikwereti zvekuzvarwa uye kukosha kwekushandisa resin dzakanyatsoongororwa uye dzakaongororwa kuti dzikurudzirwe kunyorera.Saka, izvo zvinoreva ag drainage, culvert pombi, turf drainage uye pasi pevhu kuchengetedza/kuvharirwa maapplication.Zvakare, pasi pevhu conduit inogoneka zvakare.
A: Sekuziva kwangu, ese maapplication anoshandisa musanganiswa weese ari mhandara uye akadzokororwa resin.Pane nyaya huru mbiri dziri kutamba pano.Yokutanga ndeyekuchengetedza kutendeseka kwepombi yakapedzwa kuitira kuti iite seyakagadzirwa.Zvichienderana nemhando uye kugadzirwa kwerukova rwekudzokorodza, zviyero zvakasiyana zvemhandara kune zvakadzokororwa zvemukati zvichaitika.Imwe nyaya ndeyehuwandu hwezvinhu zvakadzokororwa mushure mevatengi zviripo.Nepo vatengi vazhinji vachida kudzoreredza mapurasitiki, mazhinji, kana asiri maguta mazhinji, haana zvivakwa zvinodiwa panzvimbo yekuunganidza, kuronga uye kugadzirisa zvigadzirwa zvepakutanga.Zvakare, kune mamwe akaomesesa ekurongedza midziyo ane akawanda-layered zvimiro zvinoenderana nechigadzirwa chaanobata.Semuenzaniso, anti-oxidant zvipingamupinyi uchishandisa EVOH zvinoita kuti zviome kudzokorodza.Izvo zvinonyanya kushandiswa pakudzokorodza iHDPE asi iyo PVC pombi indasitiri inokwanisa zvakare kushandisa resin yakadzokororwa zvakare.
A: Kana yatsanangurwa zvinoenderana nemhando yenyika AASHTO M294 kana ASTM F2306, marata HDPE pombi yakagadzirwa nezvakagadzirwazve kana 100 muzana zvemhandara zvine kuita kwakaenzana.Sekureva kweNCHRP Research Report 870, marata eHDPE mapaipi anogona kugadzirwa zvakabudirira nezvinhu zvakadzokororwa kuti asangane nehupenyu hwesevhisi zvinodiwa kuti zvishandiswe pasi pemugwagwa mukuru uye njanji zvikumbiro sepombi dzakagadzirwa nevirgin resin dzakapa iyo chaiyo Un-notched Constant Ligament Stress (UCLS) kuita. zvinodiwa zvinozadzikiswa.Naizvozvo, AASHTO M294 uye ASTM F2306 miyero yemakombi eHDPE mapaipi akagadziridzwa muna 2018 kuratidza kubvumidzwa kwemhandara uye / kana kudzokororwa resin zvemukati (zvichipa izvo zvinodikanwa zveUCLS zvemaresheni akadzokororwa asangana).
A: Neshoko rimwe chete, zvinonetsa.Nepo vanhu vese vese vachida kuita izvo zvakatipoteredza, panofanirwa kunge paine marara ekudzoreredza zvivakwa panzvimbo kuti tive nebudiriro yeapo-post-consumer plastics.Maguta ane kuunganidzwa kwepamusoro uye kurongedza masisitimu anoita kuti zvive nyore kuruzhinji rwevanhu kuita zvirongwa zveparutivi rwekudzokorodza zvakare.Kureva kuti, kana uchiita kuti zvive nyore kuti mumwe munhu angopatsanura zvinodzokororwa kubva kune zvisingadzokororwe, ndipo panobva panyanya kuwanda kwekutora chikamu.Semuenzaniso, kwandinogara tine 95-gallon HDPE mudziyo umo tinoisa zvese zvinogadziriswa.Hapana chikonzero chekuparadzanisa girazi, bepa, mapurasitiki, aluminium nezvimwe zvakadaro.Inotorwa pamukoto kamwe pasvondo uye kakawanda unoona kuti midziyo yazara.Enzanisa izvi kune kanzuru inoda mabhini akawanda emhando yega yega yezvinhu uye muridzi wemba anofanirwa kuzviendesa kunzvimbo inodzokororwa.Zviri pachena kuti ndeipi system ichava nehuwandu hwekutora chikamu.Dambudziko nderomutengo wekuvaka zvivakwa zvekudzokorodza uye ndiani achazvibhadharira.
Mubvunzo: Unogona here kutaura nezvekushanya kwako kuCapitol Hill yePlastiki Indasitiri Fly-In (Sept. 11-12, 2018)?Mhinduro yakanga yakaita sei?
A: Indasitiri yepurasitiki ndiyo yechitatu yakakura kugadzira chikamu muUnited States ichipinza vashandi vangangosvika miriyoni imwe mudunhu rega rega uye congressional district.Zvinokoshesa muindasitiri yedu zvinotenderedza kuchengetedzwa kwevashandi vedu;kushandiswa kwakachengeteka kwezvinhu zvedu;uye nekutonga kwakasimba kwezvinhu, uye pamwe chete tinoenderera mberi nekushanda pakuchengetedza kwezvakatipoteredza mukati mekutakura kwepurasitiki uye hupenyu-kutenderera.Isu takanga tine vanopfuura zana nemakumi matatu nevashanu vevashandi veindasitiri yepurasitiki (kwete chete pombi) kubva kumatunhu ese vanodana zana nemakumi maviri maCongressmen, maseneta nevashandi kuti vakurukure zvinhu zvina zvakakosha zvinotarisana neindasitiri nhasi.Tichifunga nezvemitengo iri kuunzwa, kutengeserana kwemahara kunonyanya kunetsa muindasitiri yedu kubva kune zvese zvekupinza uye kunze kwenyika maonero.Neanopfuura zviuru mazana mashanu emabasa ekugadzira asingazadzike nhasi, indasitiri yepurasitiki yakamira yakagadzirira kushanda pamwe nevatungamiriri kumatunhu, nyika uye nhanho dzenharaunda kubatsira kutsvaga mhinduro dzekuvhara gaka rehunyanzvi muvashandi vemazuva ano neramangwana kudzidzisa vashandi vanokwanisa pahunyanzvi hwese. mazinga emabasa ekugadzira.
Nechekuita nepombi yepurasitiki kunyanya, kukwikwidza kwakaringana uye kwakavhurika kwezvishandiso kunofanirwa kudikanwa kune chero federal-inotsigirwa nemari purojekiti yezvivakwa.Nzvimbo zhinji dzenzvimbo dzine zvirevo zvekare zvisingabvumidze pombi yepurasitiki kukwikwidza, kugadzira "virtual monopolies" uye kukwidza mitengo.Munguva yezviwanikwa zvishoma, zvinoda mapurojekiti anoshandisa madhora emubatanidzwa kubvumira makwikwi anogona kupeta kaviri kunaka kwerutsigiro rwemubatanidzwa, kuchengetedza mari yevateresi veko.
Uye chekupedzisira, kudzokorodza uye kushandura simba kwakakosha kwekupedzisira-kwehupenyu sarudzo dzepurasitiki zvinhu.Nyika yakatarisana nemamiriro ezvinhu akaoma maererano nekugadzirisazve kugona uye misika-yekupedzisira yezvinhu zvakadzokororwa.Zvimwe zvivakwa zvinodiwa kuvandudza kushanda kweUS kudzokorodza uye kuwedzera huwandu hwezvinhu zviri kudzokororwa muUS
Zvinzvimbo zvedu zvakatambirwa zvikuru sezvo takabata zvinhu zvakakosha kumunhu wese munyika.Kureva mari, basa, mitero uye nharaunda.Kugona kwedu kuratidza kuti indasitiri yepombi yepurasitiki parizvino iri kushandisa makumi maviri neshanu muzana emabhodhoro e-post-consumer HDPE uye kuashandura kuita pombi inoshandiswa muzvivakwa zvepasi yaive yakavhura maziso kune vazhinji vevanhu vatakasangana navo.Takaratidza kuti indasitiri yedu inotora sei chigadzirwa chine 60-mazuva esherufu uye kuchishandura kuchigadzirwa chine hupenyu hwemakore zana.Ichi chimwe chinhu chine hukama nemunhu wese uye chakaratidza zvakajeka kuti indasitiri yepombi yepurasitiki inogona kuve chikamu chemhinduro yekudzivirira nharaunda.
Bepa rekugadzira rakavakirwa pane yakazara polyethylene kana polypropylene firimu rave riripo kwemakumi emakore pasina kukonzera kufara kwakanyanya - kusvika nguva pfupi yadarika.
Zvinhu zvese zvakaenzana, PET ichapfuura PBT michina uye nekushisa.Asi processor inofanirwa kuomesa zvinhu nemazvo uye inofanirwa kunzwisisa kukosha kwekushisa kwe mold mukuwana dhigirii rekristallini rinobvumira kuti mabhenefiti epolymer aonekwe.
X Ndatenda nekufunga kunyorera kuPlastiki Technology.Tine hurombo kukuona uchienda, asi kana ukachinja pfungwa dzako, tinoramba tichida kuva newe semuverengi.Ingobaya pano.
