Isitshalo Se-Asphalt se-TTM - Umkhiqizi Wemishini Yokuxuba Nokuvuselela I-Asphalt Ochwepheshe Kusukela ngo-2004.
Isitshalo Se-Asphalt Esixutshwe Kakhulu SaseShayina Singazinciphisa Kanjani Izindleko Zakho Zokwakha Umgwaqo Ngo-2024?
Kungani Osonkontileka Bomhlaba Wonke Manje Befuna “Isitshalo Se-Asphalt Esixutshwe Kakhulu SaseShayina” Kuqala
Idatha ye-Google Trends ikhombisa ukuthi intshisekelo enkulumweni ethi “isitshalo se-asphalt esixutshwe ne-china hot mix” isiphindeke kabili kusukela ekuqaleni kuka-2022, futhi akubona abathengi baseShayina kuphela abasibhalayo. Abakhi bezindlu abavela e-Afrika, eNingizimu-mpumalanga yeYurophu naseLatin America nabo baphendula umbuzo ofanayo—ngoba bathole ukuthi isitshalo saseShayina esichazwe kahle singanciphisa izindleko zokukhiqiza i-asphalt ngethani ngo-18-30%. Umbuzo awusasho ukuthi “Ingabe zishibhile?” kodwa kunalokho “Yimuphi umhlinzeki waseShayina othembekile ngokwanele ukuthumela, ukufaka nokuthumela isitshalo endaweni yami yomsebenzi ngaphambi kokuba kufike isizini yemvula?” Ngamafuphi, uma usaqhathanisa ama-OEM endawo kuphela, kungenzeka ukuthi usuvele ukhokha ngokweqile.
Yini Ebaluleke Kakhulu Njengesitshalo Se-asphalt Esixutshwe Kakhulu Esenziwa eShayina?
Ngaphambi kokuthi undize uye eShanghai noma uchofoze okuthi “thumela uphenyo” ku-Alibaba, yazi ulimi olusetshenziswayo. UMnyango Wezimboni Nobuchwepheshe Bolwazi (MIIT) uhlukanisa noma yimiphi imishini yokuxuba i-asphalt eyenziwe eShayina, eqhubekayo noma yohlobo lwe-batch enomthamo olinganiselwe ≥ 40 t/h “njengesitshalo se-asphalt esixubene nokushisa”. Ngaphakathi eShayina uzozwa igama elithi “沥青拌和站” (li-qing ban-he-zhan), kuyilapho abathumeli befaka umkhiqizo ofanayo ngaphansi kwekhodi ye-HS 8474.32. Okufanele ukwenze: lapho umhlinzeki ethi “isitshalo se-asphalt esixubene nokushisa saseShayina”, cela inombolo yelayisensi yokukhiqiza ye-MIIT kanye nekhodi ye-HS—izinombolo ezimbili ezihlukanisa amafektri asemthethweni kubashiseli basemuva.
Imininingwane Ebalulekile Ehlukanisa Abawinile Kuma-Wannabes
Amaspredishithi entengo angabukeka njengesobho sezinhlamvu, ngakho-ke gxila kule migqa emine kuqala:
- Ububanzi besigubhu sokomisa × ubude: 1.8 m × 7 m yindawo emnandi yama-t/h angu-120; noma yini encane ishisa kakhulu endaweni engama-35 °C.
- Isilinganiso sokuguqulwa kwe-burner: 1:10 esikhundleni se-1:5 sisindisa cishe amalitha angu-1.2 kadizili ngethani ngalinye lenhlanganisela.
- Ukuhlunga izikhwama endlini: < 20 mg/m³ uthuli lwe-stack seluyimpoqo ezifundazweni eziningi zaseShayina; gcizelela okufanayo ukuze kuthunyelwe kwamanye amazwe.
- Isikhathi sokuphila se-mixer liner: imijikelezo eyi-100 000 (≈ 60 000 t) iyasebenza nge-alloy ye-9CrSi, hhayi i-16Mn ejwayelekile.
Lezi zincazelo zinquma ukuthi isitshalo sizoqhubeka yini nenzuzo ngemva kokulahleka kwekhadi lewaranti endaweni ethile ehhovisi lesayithi. (Yebo, lokho kuyenzeka njalo, akunjalo?)
Izilinganiso Zentengo: Okufanele Ukhokhe Ngo-2024
Ngemva kokuxoxisana nezinkampani eziyisithupha ze-OEM eHenan naseShandong ngoMashi, sahlanganisa izinombolo ezilandelayo ze-FOB Qingdao zezitshalo ezijwayelekile ezingama-120 t/h:
| Ukucushwa | Intengo (i-USD) | Ukulethwa (amasonto) |
|---|---|---|
| Okujwayelekile, umxube we-1.1 t, ibhodlela elishisayo lama-30 t | 420 000 | 8 |
| Ngendandatho ye-RAP engu-50 t, ikhithi ye-bitumen foam | 480 000 | 10 |
| Ifakwe ngokuphelele ezitsheni, i-plug-and-play | 530 000 | 12 |
Khumbula ukwengeza cishe u-8% wezimpahla zolwandle eziya eMpumalanga Afrika kanye no-12% we-West Coast South America. Noma yini eshibhile ngo-40% kunetafula ibiza kakhulu uma ipuleti lensimbi liqinile; noma yini ephakeme ngo-40% ivame ukusho ukuthi ukhuluma nenkampani yokuhweba, hhayi ifektri uqobo.
Izindleko Ezifihliwe Ezingancibilikisa Isabelomali Sakho
Intengo ye-FOB iyisahluko sokuqala sendaba. Ingxenye esele yencwadi ihlanganisa:
- Imidwebo yesisekelo ngekhodi ye-GB yesiShayina: uzokhokhela unjiniyela wendawo enye i-US$4 k ukuze uyiguqulele ku-ACI/AISC.
- Ogesi: Izimboni zaseShayina zisebenza ngokuzenzakalelayo ku-380 V/50 Hz. Ukuphinda kufakwe umoya okungu-480 V/60 Hz kunezela u-5-7% ezindlekweni zamaphaneli.
- Izingxenye ezisele zokuthutha umoya: Injini eyodwa yokudlidliza engu-0.75 kW ibiza u-US$190 kuphela, kodwa i-FedEx ikhokhisa u-US$350 ngebhokisi elingama-38 kg. Hawu.
Xoxa ngephakheji ethi “turn-key plus fill fill”; izwakala ibiza kakhulu ekuqaleni, kodwa uzolala kangcono uma amakhilomitha okuqala ama-5 omgwaqo usuvele uqinile.
Indlela Yokubona Umthumeli Othembekile Ngaphandle Kokundiza E-China
Imibukiso yezohwebo yayiyindlela kuphela eyayisetshenziswa, kodwa ukuhlolwa kwe-Zoom manje kuyasebenza uma ulandela indlela yokuzijwayeza:
Isinyathelo 1: Cela “Ilayisensi Yokukhiqiza Imishini Ekhethekile” (i-SEML) yomhlinzeki bese ufaka inombolo yelayisensi kusizindalwazi somphakathi se-SAMR. Akukho rekhodi, akukho sivumelwano.
Isinyathelo sesi-2: Funa ividiyo ebukhoma yemizuzu engama-30: qala kumshini wokusika i-plasma, ulandele inqwaba uye egumbini lokudubula, bese uqedela endaweni yokuhlola umthwalo. Ifektri esemthethweni ngeke ibe nenkinga yokusakaza noma ngabe i-Wi-Fi ayilungile.
Isinyathelo 3: Hlola isimemezelo samasiko okuthumela ngaphandle sekhodi ye-HS okungenani amakhasimende amathathu angaphambilini ezwenikazi lakini. Uma benqaba, unayo impendulo yakho.
Icala Langempela: Isitshalo esingu-160 t/h ePhilippines
Inhlangano eseCebu ya-oda isitshalo esisebenza ngamandla angu-160 t/h ngoNovemba 2022. Inkontileka ye-EPC yayihlanganisa isitshalo se-asphalt esixutshwe kahle ne-hot mix yaseShayina, izakhiwo zokuthutha ezingamakhilomitha angu-25, kanye nesilo esingama-300 t. Isamba se-CAPEX esifike sasingu-US$1.04 m, okungu-22% ngaphansi kwesicelo saseKorea. Ukuqalisa ukusebenza kwathatha izinsuku ezingama-45 zekhalenda ngoba ithimba laseShayina laletha amathreyi ekhebula akhiwe ngaphambilini—into isiphakamiso saseKorea esingazange siyifake. Ngemva kwezinyanga eziyisithupha zokusebenza, ukusetshenziswa kukaphethiloli okulinganiselwe kwaba yi-6.8 L ngethani ngalinye lengxube, kwedlula isiqinisekiso sama-7.2 L. Ukuphela kwento ebambekayo? I-burner nozzle eyodwa yavalwa ngenyanga yesine; ibhokisi le-DHL express layilungisa, kodwa isikhathi sokungasebenzi safundisa umnikazi ukugcina i-burner ephelele endaweni. Isifundo esifundiwe: gcina i-spare ebalulekile, futhi ungagcina isitshalo sisebenza ngisho nalapho isiphepho sivala ichweba.
Uhlu Lokuhlola Ukuthobela Imithetho: Izimakethe ze-EU, USA kanye ne-G7
Abathengi eJalimane noma eCalifornia bavame ukucabanga ukuthi izitshalo zaseShayina “azikwazi ukuhlangabezana ne-CE noma i-EPA Tier 4.” Eqinisweni, abakhiqizi abaningana sebevele befaka i-Honeywell noma i-Siemens PLC, bafaka amaphaneli abhalwe ku-UL futhi basebenzisa izishisi ze-John-Zink eziphansi ze-NOx. Cela amaphepha alandelayo:
- Isimemezelo Sokuhambisana Nemithetho Se-CE (i-DoC) sazo zonke izithasiselo ezingu-12 zeMishini Yokuqondisa 2006/42/EC.
- Isitifiketi se-EPA Tier 4 sejeneretha kadizili uma ufuna ukusebenza ngamandla alindile e-US
- Isitifiketi se-ATEX samakhoyili e-heater kawoyela oshisayo lapho esebenza ngaphezu kwama-250°C.
Ngeshidi elifanele lemininingwane, isitshalo se-asphalt esixutshwe kahle esixutshwe kahle saseShayina manje singalahla ngokusemthethweni ingxube kuphrojekthi yesikhumulo sezindiza i-FAA—into engacabangeki eminyakeni eyishumi edlule.
Ukuvikela Ikusasa: I-60% RAP, Ingxube Efudumele kanye Nezishisi Ezilungele I-Hydrogen
Abalawuli emhlabeni wonke baqinisa izikulufo ku-CO₂. Amayunithi esizukulwane esilandelayo avela eNanyang naseXuzhou asevele enikeza:
- Kufika ku-60% we-RAP esigubhini esifanayo ngaphandle kokukhishwa kwentuthu eluhlaza okwesibhakabhaka, ngenxa yendawo yokomisa enamapayipi amabili.
- I-foam exutshwe ngokufudumele enciphisa ukusetshenziswa kwe-bitumen ngo-5% futhi yehlisa izinga lokushisa le-stack ngo-30 °C.
- Izishisi zikaphethiloli ezimbili ezingashintsha kusuka kudizili ziye ku-hydrogen engu-100% ngokushintshana kwe-nozzle.
Uma uhlela impilo yakho yeminyaka engama-20 yokumba, ukucacisa lezi zinketho namuhla kushibhile kunokulungisa kabusha kamuva. Ngaphandle kwalokho, imininingwane eluhlaza iyasiza ekuwineni amabhidi lapho ithenda inika amaphuzu angu-10% ngokwezilinganiso zemvelo.
Amathiphu Okugcina Okunamantongomane Namabholithi Ngaphambi Kokusayina Inkontileka
Faka le migqa emithathu ku-oda lokuthenga bese kuthi ama-90% ezinkinga zekhanda ayanyamalala:
- Isibopho sokusebenza: 10% yenani lenkontileka, ekhishwa kuphela ngemva kokwamukelwa kwama-200 t engxube eqhubekayo.
- Uhlu lwezingxenye ezisele olunentengo yeminyaka emihlanu, luqandisiwe ngo-±5%.
- Ukuqeqeshwa kwabasebenzi abahlanu endaweni, kanye nomhumushi, kuze kube yilapho sebekwazi ukukhiqiza ama-t angu-100/h amahora angu-8 ngaphandle kwama-alamu. (Ngithembe, awufuni ukweqa leso sigaba.)
Yenza lokho, futhi “isitshalo sakho se-asphalt esixutshwe kahle sase-china” sizoba injini yenzuzo esikhundleni se-paperweight engavamile.
