TTM Asphalt Plant - Wopanga Zida Zosakaniza ndi Kubwezeretsanso za Asphalt Waukadaulo Kuyambira 2004.
Kodi Chomera Chosakaniza Chotentha cha Asphalt ku China Chimawononga Ndalama Zingati Ndipo Kaboni Ingawononge Bwanji Ndalama mu 2024?
Chifukwa Chake Makampani Omanga Misewu Padziko Lonse Akuganizira Ukadaulo Watsopano wa China Wobwezeretsanso Zinthu
Ngati mwayang'ana pa malo aliwonse ogwirira ntchito posachedwapa, mwina mwawona phokoso lozungulira fakitale yosakaniza zinthu zotentha ya asphalt ku China . Machitidwewa akulonjeza kusintha mpaka 50% ya zinthu zosakanikirana bwino ndi bitumen ndi njira yobwezeretsanso asphalt pavement (RAP), zomwe zimachepetsa kwambiri ndalama zomwe zimagwiritsidwa ntchito. Koma kodi kulengeza kumeneku n'koyenera, kapena ndi njira ina yotsatsira malonda "yobiriwira"? Tiyeni tifufuze zambiri zenizeni za polojekitiyi m'malo mwa mabulosha owala.
Kodi Chimachitika Ndi Chiyani Mkati mwa Chosakaniza Chotentha Chobwezeretsanso?
Zomera zachikhalidwe zimatenthetsa zinthu za virgin aggregates kufika pa 170-180 °C, kenako nkuzipaka ndi bitumen yatsopano. Chosakaniza chotenthetsera chopangidwa ndi China chimawonjezera "ng'oma yowumitsa ya RAP" yowonjezera yomwe imatenthetsa phula lophwanyidwa kufika pa 130 °C mu chipinda chochepetsedwa ndi mpweya. Izi zimaletsa kukalamba kwa binder pamene chinyezi chikutuluka. RAP yotenthetsera kwambiri imasakanizidwa ndi zinthu za virgin zotenthetsera kwambiri, kotero kutentha komaliza kwa kusakaniza kumakhala pafupifupi 155 °C—15 °C pansi pa zosakaniza zachizolowezi. Kutentha kotsika kumakhala kofanana ndi mafuta ochepa, utsi wochepa, komanso anansi osangalala okhala pafupi ndi chomeracho. Zosavuta choncho, innit?
Zigawo Zofunika Zomwe Zimapangitsa Kusiyana
- Mabinki oyezera RAP okhala ndi zikopa ziwiri - chotsani zidutswa zazikulu zomwe zimapangitsa kuti pakhale malo ozizira mumsanganizo.
- Kuumitsa kofanana ndi madzi pogwiritsa ntchito masensa a infra-red - kukonza chinyezi nthawi yeniyeni mkati mwa ± 0.2%.
- Kusonkhanitsa fumbi m'magawo atatu - chimphepo chachikulu, malo osungira matumba, ndi scrubber yonyowa kumasunga mpweya wa PM pansi pa 20 mg/m³, zomwe zimakwaniritsa ngakhale zofunikira za ku California.
- Mizere ya bitumen yokhala ndi jekete la mafuta otentha - sungani kutentha kwa 165 °C ndi ±2 °C molondola, kupewa kulekanitsa pakapita nthawi yayitali.
Kodi 50% RAP Ingapiriredi Magalimoto Ambiri?
Anthu okayikira akuda nkhawa kuti ma mixes a high-RAP amasweka pansi pa katundu wolemera wa ma axle. Kafukufuku wa 2023 wochitidwa ndi Chang'an University adatsata msewu waukulu wochokera ku Shandong womwe unamangidwa ndi 48% RAP panjira yovalira. Pambuyo pa ma ESAL 14.2 miliyoni (ofanana ndi ma axle single loads), International Roughness Index idakwera ndi 0.8 mm/km yokha, pansi kwambiri pa 2.0 mm/km yokonza. Kusanthula kwa microscopic kunawonetsa kuti chogwirira chobwezerezedwanso chinali ndi modulus (G*) yofanana ndi virgin PG 76-22, chifukwa cha ma rejuvenator osinthidwa ndi polymer omwe adawonjezedwa pa 0.6% potengera kulemera kwa kusakaniza. Kumasulira: msewuwo unkachita ngati watsopano, koma unali wotsika ndi 28%.
Kodi Zomera zaku China Zimasunga Bwanji Ndalama Zotsika Kwambiri?
Opanga akumadzulo nthawi zambiri amalemba mtengo wa USD 5–6 miliyoni pa fakitale yobwezeretsanso zinthu yotentha ya 240 tph. Fakitale yosakaniza zinthu yotentha ya asphalt yaku China imafika pa mtengo wa USD 2.8 miliyoni, ngakhale mutatumiza ndi kulipira msonkho wochokera kunja. Zinthu zitatu zimayambitsa kusiyana:
- Kuphatikiza koyima - Mafakitale aku China amapanga ma burners awoawo, ma gearbox, ndi ma cages okhala ndi matumba, ndikuchepetsa kuchuluka kwa zinthu zomwe anthu ena angagule.
- Kukula** – kufunika kwa misewu yayikulu m'dziko muno kumaposa makilomita 4,000 pachaka, kotero ogulitsa amayendetsa mizere yopangira magalimoto maola 24 pa sabata, zomwe zimapangitsa kuti magalimoto azigwiritsidwa ntchito kwambiri.
- Ndalama zothandizira boma pa zipangizo “zobiriwira” – ogulitsa kunja amalandira kuchotsera kwa VAT kwa 13%, phindu lomwe limaperekedwa mwakachetechete kwa ogula akunja.
ROI Yapadziko Lonse: Kafukufuku wa Nkhani ya ku Nigeria
Lagos State Public Works idagula fakitale yaku China ya 200 tph mu kotala loyamba la 2022, ikufuna matani 120 000 a mix roads for airport link. Mtengo wa dizilo: USD 0.92 pa lita; RAP ikupezeka kwaulere kuchokera ku mphero zakomweko. Kontrakitala adapeza 47% ya RAP, ndikusunga 31% pa bitumen ndi 22% pa ma aggregates. Kubweza kunafika m'miyezi 14—osati zaka 10 zomwe mumamva m'mawu a msonkhano. Kuphatikiza apo, mpweya wa CO₂ unatsika ndi 38%, zomwe zinathandiza boma kukwaniritsa mapangano a ngongole za AfDB. Sizoipa, eti?
Nanga Bwanji Zothandizira Pambuyo Pogulitsa—Zida Zowonjezera Ndi Zoopsa Kapena Ulendo Wosalala?
Ogula nthawi ina ankaopa kuti zida "zotsika mtengo" zaku China zikutanthauza kuti nthawi yogwira ntchito inali yochepa kwa milungu ingapo kuyembekezera sensa ya 2 kg. Nthawi yasintha. Makampani opanga zida zapamwamba tsopano amagwiritsa ntchito malo osungira zida ku Nigeria, Peru, ndi Poland, zomwe zimapangitsa kuti 90% ya mayunitsi osinthika azikhala m'malo am'deralo. Module ya IoT yoyendetsedwa ndi VPN pa fakitale iliyonse imatumiza telemetry ku Chengdu HQ; ma algorithms oneneratu amawonetsa unyolo wosweka wa elevator maola 150 ogwirira ntchito asanagwire ntchito. Makasitomala amalandira invoice yodziwikiratu ndipo amatha kusankha DHL Express kapena pickup yakomweko. Nthawi yogwira ntchito imakhala pafupifupi maola 1.8 pa maola 1,000 ogwirira ntchito, mofanana ndi makampani aku Europe.
Ndondomeko Yoyendetsera Ntchito: Kodi Dziko Lanu Lidzalola 50% RAP?
Musanagwiritse ntchito njira ina, yang'anani zomwe zili m'deralo. Ku France, muyezo wa NF P 98-150 umaletsa RAP pa 30% pa malo olowera pamwamba, koma Germany imalola 50% ngati kusakaniza kobwezeretsedwako kupitilira mayeso a Alkali-Silica Reactivity. Pakadali pano, mayiko angapo aku US akadali ndi malire a 20%. Nkhani yabwino: fakitale yosakaniza yotenthetsera ya asphalt yaku China ikhoza kusintha pakati pa 15% ndi 60% RAP pongosintha liwiro la elevator ndi mbiri ya burner, kuti mupitirize kutsatira malamulo pamene mukupempha kuti pakhale malire apamwamba.

Mfundo Yofunika Kwambiri: Kodi Ndalama Zoyikira Ndalama Zili Zofunika Mu 2024?
Popeza phula limagulitsidwa pa USD 520 pa tani ndipo kuchuluka kwake kukukwera ndi 9% pachaka, gawo lililonse la RAP limasunga pafupifupi USD 7.40 pa tani imodzi ya zosakaniza. Chomera cha 200 tph chomwe chimagwira ntchito maola 2,000 pachaka chimapanga 400 000 t; pa 45% RAP, ndiye kuti USD 1.33 miliyoni amasungidwa chaka chilichonse. Ganizirani za carbon credits ndi ndalama zochotsera zinyalala, ndipo chomera chosakaniza cha asphalt chotentha cha ku China chimakhala chuma cha ROI chachangu kwambiri m'gulu lanu—pokhapokha ngati mitengo yamafuta itatsika pansi pa USD 40, zomwe zingakhale zovuta kwambiri kwa akatswiri ofufuza. Kodi mwakonzeka kulankhula ndi ogulitsa, kapena mukudikirabe ukadaulo "wangwiro" womwe sungabwere?
