  • Kuphunzira Za Rubber Wa Matayala Obwezerezedwanso & Mipando Yamakono Ya Asphalt

    Mndandanda wa ma webinar kuchokera ku National Asphalt Pavement Association wakhazikitsidwa kuti uwonetsere ubwino wa zinthu zomwe zikupita patsogolo

    Kubwezeretsanso matayala ndi njira yosinthira matayala akale amoyo kapena osafunikira kukhala zinthu zomwe zitha kugwiritsidwa ntchito pazinthu zatsopano.Matayala akumapeto kwa moyo nthawi zambiri amakhala ofuna kukonzanso akasiya kugwira ntchito chifukwa chakuvala kapena kuwonongeka ndipo sangathenso kupondedwanso kapena kukomedwanso.

    Malinga ndi makampani opanga matayala, kukonzanso matayala ndi nkhani yabwino kwambiri.Kuchulukira kwa matayala otayika kwachepa kuchoka pa biliyoni mu 1991 kufika pa 60 miliyoni pofika chaka cha 2017 ndipo makampani a asphalt ndi chinthu chachikulu chochepetsera chiwerengero cha matayala m'malo otayira.

    Kugwiritsira ntchito mphira wapansi kunapanga 25% ya kugwiritsidwa ntchito kwa matayala mu 2017. Labala ya pansi imagwiritsidwa ntchito popanga zinthu zingapo koma ntchito yaikulu ya mphira wapansi ndi mphira wa phula, pogwiritsa ntchito mapaundi pafupifupi 220 miliyoni kapena matayala 12 miliyoni pachaka.Ogwiritsa ntchito kwambiri mphira wa phula ndi madera aku California ndi Arizona, kutsatiridwa ndi Florida, omwe akuyembekezeka kukula m'maiko enanso.

    Recycled tire rabara (RTR) kuchokera ku matayala a zinyalala akhala akugwiritsidwa ntchito mu asphalt ndi makampani opaka kuyambira m'ma 1960.RTR yakhala ikugwiritsidwa ntchito ngati asphalt binder modifier and asphalt mix additives in the gap-graded and open-graded asphalt mix and surface treatments.

    Labala ya matayala yobwezerezedwanso imakhala yopangidwanso ndi mphira wa matayala omwe adapangidwa kukhala tinthu tating'ono kwambiri kuti tigwiritse ntchito ngati phula.Kuonjezera mphira wa matayala pansi pa asphalt kungathandize kupititsa patsogolo kukana kwa rutting, skid resistance, khalidwe la kukwera, moyo wapanjira komanso kuchepetsa phokoso la pamsewu.Kuonjezera mphira kumadzi a asphalt kumachepetsa ukalamba komanso makutidwe ndi okosijeni wa binder, zomwe zimawonjezera moyo wapanjira pochepetsa kuphulika ndi kusweka.

    Kugwira ndi kuphwanyidwa kwa matayala ndi ndondomeko yokonzedwa bwino ndi kuyang'aniridwa kuti apange zinthu za rabara zoyera komanso zogwirizana kwambiri.Rabara ya crumb imapangidwa mwa njira yopera matayala a rabara kukhala tinthu tating'onoting'ono.

    Panthawiyi, waya ndi ulusi wa tayala amachotsedwa.Chitsulocho chimachotsedwa ndi maginito ndipo fiber imachotsedwa ndi aspiration.Kukonza matayala pogwiritsa ntchito cryogenic fracturing kumaphatikizapo kudula zidutswa zazikuluzikulu za tayala kukhala ting'onoting'ono, nthawi zambiri tinthu tating'onoting'ono ta 50 mm, pogwiritsa ntchito zida zakuthwa zachitsulo.Tizidutswa tating'ono ting'ono timeneti timaundana ndikusweka.Tinthu tamphira timasefa ndikugawidwa m'magulu osiyanasiyana, monga momwe kasitomala amafotokozera.The chifukwa mphira particles zonse kakulidwe ndi woyera kwambiri.Makina onyamula katundu amathandizira kuonetsetsa kuti thumba likulemera moyenerera ndikuchotsa kuipitsidwa.

    Bungwe la National Asphalt Pavement Association (NAPA), likhala likuchititsa Kumene Rubber Meets the Road Webinar Series chilimwechi pa mphira wa matayala opangidwanso ndi phula.
