Tony Radoszewski, Plastics Pipe Institute tus thawj tswj hwm, tham txog cov ntsiab lus siv hauv cov yeeb nkab thiab hloov cov pob khoom nrog 60-hnub txee lub neej rau hauv cov khoom nrog 100-xyoo kev pab cuam lub neej.
Tony Radoszewski yog tus thawj tswj hwm ntawm Plastics Pipe Institute - lub koom haum loj ntawm North American kev lag luam sawv cev rau txhua ntu ntawm kev lag luam yeeb nkab yas.
Muaj ntau qhov kev pab cuam ntawm kev siv cov khoom siv tom qab cov khoom siv hauv kev ntim khoom, tab sis muaj lwm qhov kev lag luam rov ua dua tshiab uas tsis tau tham txog: cov yeeb nkab tsim nrog cov khoom siv rov ua dua tshiab.
Tshawb xyuas kuv hauv qab Q&A nrog Tony Radoszewski, tus thawj tswj hwm ntawm Plastics Pipe Institute, Dallas, TX, qhov chaw nws tham txog cov khoom siv rov ua dua tshiab hauv cov yeeb nkab siv;yuav ua li cas cov ntaub ntawv rov ua dua;thiab nws txoj kev mus rau Washington, DC ua ib feem ntawm 2018 Plastics Fly-In.
Q: Thaum twg koj pib pom PPI cov tswv cuab pib siv cov khoom siv rov qab siv dua tshiab?Dab tsi yog qee qhov kev siv yeeb nkab?
A: Ntseeg nws los tsis, kev lag luam corrugated yas yeeb nkab tau siv tom qab cov neeg siv khoom siv dua HDPE rau ntau xyoo lawm.Cov pobzeb ua liaj ua teb, uas yog siv los txav dej tawm ntawm thaj av ua liaj ua teb los txhim kho cov qoob loo, tau siv cov fwj mis thiab cov tshuaj ntxuav tais diav rov qab mus rau xyoo 1980s.Rau cov ntawv thov yeeb nkab, cov khoom siv tom qab siv tau tiag tiag tsuas yog siv rau hauv daim ntawv thov kev nqus dej.Ntawd yog, cov yeeb nkab tsis muaj zog vim muaj kev lav phib xaub thiab qhov yuav tsum tau siv cov resins uas tau raug soj ntsuam kom zoo thiab kuaj xyuas rau kev siv siab.Yog li, qhov ntawd txhais tau hais tias ag kua, culvert yeeb nkab, turf drainage thiab underground retention / detention applications.Tsis tas li ntawd, underground conduit kuj tseem muaj.
A: Raws li kuv paub, txhua daim ntawv thov siv ua ke ntawm ob qho tib si nkauj xwb thiab cov khoom siv rov ua dua tshiab.Muaj ob qhov teeb meem loj ntawm kev ua si ntawm no.Thawj yog tswj kev ncaj ncees ntawm cov yeeb nkab tiav kom nws tuaj yeem ua tau raws li tsim.Nyob ntawm qhov ua tau zoo thiab kev ua kom zoo ntawm cov kwj dej rov ua dua, qhov sib txawv ntawm cov nkauj xwb rau cov ntsiab lus siv dua tshiab yuav tshwm sim.Lwm qhov teeb meem yog tus nqi ntawm cov khoom siv rov qab siv dua tshiab muaj.Txawm hais tias feem ntau cov neeg siv khoom xav rov ua dua cov yas, ntau, yog tias tsis yog ntau lub nroog, tsis muaj cov txheej txheem tsim nyog rau hauv qhov chaw los sau, txheeb thiab ua cov khoom qub.Tsis tas li ntawd, muaj qee lub thawv ntim khoom nruj uas muaj ntau txheej txheej nyob ntawm seb lawv tuav cov khoom dab tsi.Ua piv txwv, cov khoom tiv thaiv oxidant siv EVOH ua rau nws nyuaj rau rov ua dua.Cov khoom siv ntau tshaj plaws rau kev rov ua dua tshiab yog HDPE tab sis PVC yeeb nkab kev lag luam kuj muaj peev xwm siv cov khoom siv rov ua dua tshiab thiab.
A: Thaum tau teev tseg raws li lub teb chaws tus qauv AASHTO M294 lossis ASTM F2306, corrugated HDPE yeeb nkab ua nrog cov ntsiab lus rov ua dua lossis 100 feem pua cov ntsiab lus nkauj xwb muaj qhov sib npaug.Raws li NCHRP Kev Tshawb Fawb Daim Ntawv Qhia 870, corrugated HDPE kav tuaj yeem ua tiav nrog cov khoom siv rov ua haujlwm kom tau raws li qhov kev pab cuam lub neej zoo ib yam rau kev siv hauv qab txoj kev loj thiab kev tsheb ciav hlau raws li cov kav dej ua los ntawm nkauj xwb tau muab qhov tshwj xeeb Un-notched Constant Ligament Stress (UCLS) kev ua tau zoo. raws li qhov yuav tsum tau ua.Yog li, AASHTO M294 thiab ASTM F2306 cov qauv rau cov kav dej HDPE corrugated tau hloov kho xyoo 2018 kom muaj kev cuam tshuam rau cov ntsiab lus ntawm nkauj xwb thiab / lossis cov khoom siv rov ua dua tshiab (muab UCLS cov cai rau cov khoom siv rov ua dua tshiab).
A: Hauv ib lo lus, nyuaj.Thaum txhua tus neeg feem coob xav ua qhov zoo ib puag ncig, yuav tsum muaj cov khoom pov tseg rov qab los rau hauv qhov chaw kom muaj kev vam meej ntawm cov khoom siv tom qab siv cov yas.Lub nroog uas muaj cov kev sau zoo tshaj plaws thiab kev txheeb cais ua rau nws yooj yim rau cov pej xeem los koom nrog cov kev pab cuam rov ua dua tshiab.Qhov ntawd yog, qhov yooj yim dua koj ua rau ib tus neeg yooj yim cais cov khoom siv rov ua dua tshiab los ntawm cov khoom siv rov ua dua tshiab, qhov kev koom tes ntau dua yuav yog.Piv txwv li, qhov twg kuv nyob peb muaj 95-gallon HDPE thawv uas peb tso tag nrho cov recyclables.Tsis tas yuav cais cov iav, ntawv, yas, aluminium li ntawd.Nws tau khaws ntawm qhov thaiv ib zaug ib lub lim tiam thiab ntau zaus koj tuaj yeem pom tias cov thawv ntim puv.Sib piv qhov no rau lub nroog uas xav tau ntau lub thawv rau txhua hom khoom thiab tus tswv tsev yuav tsum coj mus rau qhov chaw rov ua dua tshiab.Nws yog qhov tseeb zoo nkauj uas qhov system yuav muaj kev koom tes ntau dua.Qhov kev sib tw yog tus nqi los tsim cov khoom siv rov ua dua tshiab thiab leej twg yuav them rau nws.
Q: Koj puas tuaj yeem tham txog koj qhov kev mus ntsib Capitol Hill rau Plastics Industry Fly-In (Sept. 11-12, 2018)?Cov lus teb zoo li cas?
A: Kev lag luam yas yog qhov thib peb loj tshaj plaws hauv kev tsim khoom hauv Tebchaws Meskas uas ntiav ze li ib lab tus neeg ua haujlwm hauv txhua lub xeev thiab pawg thawj coj saib xyuas.Peb lub luag haujlwm tseem ceeb hauv kev lag luam yog nyob ntawm kev nyab xeeb ntawm peb cov neeg ua haujlwm;kev nyab xeeb siv ntawm peb cov khoom;thiab kev tswj xyuas kom ruaj khov ntawm cov ntaub ntawv, thiab ua ke peb txuas ntxiv ua haujlwm ntawm lub luag haujlwm ib puag ncig kev saib xyuas thoob plaws hauv cov khoom siv plastics thiab lub neej voj voog.Peb muaj ntau tshaj 135 tus kws tshaj lij kev lag luam plastics (tsis yog yeeb nkab) los ntawm thoob plaws lub tebchaws hu rau 120 Congressmen, Senators thiab cov neeg ua haujlwm los tham txog plaub qhov teeb meem tseem ceeb yog kev lag luam ntsib niaj hnub no.Nyob rau hauv lub teeb ntawm tariffs tau qhia, kev lag luam dawb yog qhov kev txhawj xeeb loj hauv peb txoj kev lag luam los ntawm ob qho tib si ntshuam thiab xa tawm.Nrog ntau dua 500,000 txoj haujlwm tsim khoom yuav tsis tiav niaj hnub no, kev lag luam yas tau npaj ua haujlwm nrog kev koom tes nrog cov thawj coj ntawm tsoomfwv, xeev thiab hauv cheeb tsam los pab nrhiav kev daws teeb meem los kaw cov kev txawj sib txawv hauv cov neeg ua haujlwm niaj hnub no thiab yav tom ntej los cob qhia cov neeg ua haujlwm tsim nyog ntawm txhua qhov kev txawj ntse. qib rau kev tsim khoom.
Hais txog cov yeeb nkab yas tshwj xeeb, kev ncaj ncees thiab qhib kev sib tw rau cov ntaub ntawv yuav tsum tau tsim rau txhua qhov kev tsim kho vaj tse uas tseem ceeb hauv tsoomfwv.Ntau qhov chaw hauv cheeb tsam muaj cov lus qhia qub uas tsis tso cai rau cov yeeb nkab yas sib tw, tsim "virtual monopolies" thiab tsav cov nqi.Nyob rau lub sijhawm ntawm cov peev txheej tsawg, xav tau cov haujlwm uas siv tsoomfwv cov nyiaj tau los tso cai rau kev sib tw tuaj yeem ua ob npaug ntawm kev txhawb nqa tseemfwv qib siab, txuag cov neeg them se hauv zos.
Thiab qhov kawg, kev rov ua dua tshiab thiab lub zog hloov pauv yog qhov tseem ceeb kawg ntawm lub neej kev xaiv rau cov ntaub ntawv yas.Lub teb chaws tab tom ntsib qhov teeb meem tseem ceeb ntawm cov khoom siv rov ua dua tshiab thiab kev lag luam kawg rau cov khoom siv rov ua dua tshiab.Ntxiv kev tsim kho vaj tse yog tsim nyog los txhim kho kev ua tau zoo ntawm US recycling thiab nce cov khoom siv rov ua dua tshiab hauv Asmeskas
Peb txoj haujlwm tau txais txiaj ntsig zoo heev thaum peb kov cov khoom tseem ceeb rau yuav luag txhua tus hauv lub tebchaws.Xws li cov nqi, kev ua haujlwm, se thiab ib puag ncig.Peb lub peev xwm los ua kom pom tau tias kev lag luam cov yeeb nkab yas yog tam sim no siv 25 feem pua ntawm cov neeg siv khoom HDPE fwj tom qab thiab hloov lawv mus rau hauv cov yeeb nkab siv hauv av hauv av yog qhov qhib qhov muag rau ntau tus neeg peb tau ntsib.Peb tau pom tias peb txoj kev lag luam yuav siv li cas rau cov khoom lag luam uas muaj 60-hnub txee lub neej thiab hloov nws mus rau ib yam khoom uas muaj 100-xyoo kev pab cuam lub neej.Qhov no yog ib yam uas txhua leej txhua tus hais txog thiab qhia meej meej tias kev lag luam yas yeeb nkab tuaj yeem yog ib feem ntawm kev daws teeb meem rau kev tiv thaiv ib puag ncig.
Cov ntawv hluavtaws raws li cov ntawv ntim polyethylene lossis polypropylene zaj duab xis tau nyob ib puag ncig rau xyoo lawm tsis ua rau muaj kev txaus siab ntau - txog thaum tsis ntev los no.
Txhua yam sib npaug, PET yuav ua tau zoo dua PBT mechanically thiab thermally.Tab sis tus processor yuav tsum qhuav cov khoom kom zoo thiab yuav tsum nkag siab qhov tseem ceeb ntawm pwm kub hauv kev ua tiav qib ntawm crystallinity uas tso cai rau lub ntuj zoo ntawm cov polymer kom paub txog.
X Ua tsaug rau kev txiav txim siab tso npe rau Plastics Technology.Peb thov txim uas koj mus, tab sis yog tias koj hloov siab, peb tseem nyiam kom muaj koj ua tus nyeem.Nyem qhov no xwb.
