Ko Kushandiswa Kwekugadzira Asphalt Hot Recycling Plant muChina Kunodhura Sei uye Kunodhura Sei Carbon muna 2024?
Nei Bhizinesi reKuvaka Migwagwa Pasirose Riri Kutarisa Tekinoroji Inopisa yeChina yeKudzokorodza Zvinhu
Kana wakambotarisa chero puratifomu yezvivakwa munguva pfupi yapfuura, pamwe wakaona ruzha rwakawanda pamusoro pefekitori yekusanganisa zvinhu zvinopisa zveasphalt muChina . Masisitimu aya anovimbisa kutsiva kusvika ku50% yemidziyo yebitumen nebitumen nereclaimed asphalt pavement (RAP), zvichideredza mari yezvinhu zvakanyanya. Asi manyepo aya akakodzera here, kana kuti ingori imwe nzira yekushambadzira "yakasvibira"? Ngationgororei ruzivo rwechokwadi rwemapurojekiti panzvimbo pemabhurocha anopenya.
Chii Chinoitika Mukati Memusanganiswa Unopisa Wekudzokorodza?
Zvirimwa zvechinyakare zvinopisa ma virgin aggregates kusvika 170-180 °C, zvobva zvaaputira nebitumen itsva. Muchina wekusanganisa zvinhu zvinopisa wakavakwa kuChina unowedzera "RAP drying drum" inowedzera kupisa asphalt yakakuyiwa kusvika 130 °C mukamuri ine oxygen shoma. Izvi zvinodzivirira kukwegura kwebinder uku zvichibvisa hunyoro. RAP inopisa kwazvo inozosanganiswa nezvinhu zvinopisa zvakanyanya, saka tembiricha yekupedzisira yemusanganiswa inoramba iri pa155 °C—15 °C pasi pemisanganiswa yakajairika. Tembiricha yakaderera inoenzana nemafuta mashoma, utsi hushoma, uye vavakidzani vanofara vanogara pedyo nechirimwa. Zviri nyore kudaro, handiti?
Zvinhu Zvikuru Zvinoita Musiyano
- Mabhini eRAP ane jira reRAP ane jira rechipiri - bvisa zvidimbu zvakakura zvinogadzira mavara anotonhora mumusanganiswa.
- Kuomesa mvura panguva imwe chete uchishandisa masensa e infra-red - kugadzirisa hunyoro panguva chaiyo mukati me ±0.2%.
- Kuunganidzwa kweguruva rine matanho matatu - dutu guru, nzvimbo inochengeterwa mabhegi, uye wet scrubber zvinochengetedza utsi hwePM huri pasi pe20 mg/m³, zvichisangana nezvinodiwa zveCalifornia.
- Mitsetse yebhitumini ine mafuta anodziya - chengetedza 165 °C ne ±2 °C chaiyo, zvichidzivirira kuparadzaniswa panguva yekufamba kwenguva refu.
Ko 50% RAP Inogona Kudzivirira Here Kupfuura Vanhu Vakawanda Vari Kufamba Nemotokari?
Vasingafungi kuti misanganiswa yeRAP ine simba rakakwira inotsemuka pasi pemitoro inorema yeaxle. Ongororo yakaitwa muna 2023 neChang'an University yakatevedza mugwagwa mukuru unobva kuShandong wakavakwa ne48% RAP munzira yekupfeka. Mushure me14.2 miriyoni ESALs (yakaenzana neaxle imwe chete), International Roughness Index yakakwira ne0.8 mm/km chete, pasi pe2.0 mm/km yekugadzirisa. Ongororo yemicroscopic yakaratidza kuti binder yakadzokororwa yaive necomplex modulus (G*) yakafanana nevirgin PG 76-22, nekuda kwepolymer-modified rejuvenators yakawedzerwa pa0.6% nehuremu hwemusanganiswa. Dudziro: mugwagwa waiita semutsva, asi waidhura ne28% pasi.
Zvirimwa zvekuChina Zvinoita Sei Kuti Mari Inoshandiswa Irambe Yakaderera Zvikuru?
Vagadziri vekuMadokero vanowanzo taura kuti fekitari inodzokorodza zvinhu inopisa ine simba re240 tph inoshandisa USD 5–6 miriyoni. Imwe fekitari inosanganisa zvinhu zvinopisa zvinogadzirwa neasphalt muchina yakafanana inosvika USD 2.8 miriyoni, kunyangwe mushure mekutumira zvinhu nemitero yekupinza zvinhu kunze kwenyika. Zvinhu zvitatu zvinokonzera musiyano uyu:
- Kubatanidzwa kwakamira - Mafekitori ekuChina anogadzira maburner awo, magiya, uye macage ekuisa mabhegi, zvichideredza mari yekuwedzera inoshandiswa nevamwe.
- Chikero** – kudiwa kwemigwagwa mikuru munyika kunodarika 4 000 km pagore, saka vatengesi vanogadzira migwagwa nguva dzese, mazuva ese, mazuva ese, vachibvisa mari yekutenga migwagwa.
- Rubatsiro rwehurumende rwekushandisa michina "yakasvibira" - vanotumira kunze kwenyika vanowana 13% VAT rebate, pundutso inopihwa chinyararire kune vanotenga kunze kwenyika.

Nzira Yekutonga: Nyika Yenyu Ichabvumira 50% RAP Here?
Usati watanga kushandisa nzira iyi, tarisa zvirevo zvemuno. MuFrance, NF P 98-150 standard inovhara RAP pa30% yenzvimbo dzepamusoro, asi Germany inobvumira 50% kana musanganiswa wakadzokororwa ukapasa bvunzo yeAlkali-Silica Reactivity. Panguva iyi, nyika dzinoverengeka dzemuUS dzichiri kutamba ne20%. Mashoko akanaka: fekitari yekusanganisa hot asphalt yekuChina inogona kuchinja pakati pe15% ne60% RAP nekungogadzirisa kumhanya kweelevator uye burner profile, kuitira kuti urambe uchitevedzera mitemo iyi paunenge uchikurudzira kuti pave nemiganhu yakakwira.
