SMA-Stone Mastic Asphalt-sichinthu chinanso cha phula. Ndi chizindikiro chakuchita. Pamene misewu ikuluikulu imanyamula magalimoto opitilira 30,000+ tsiku lililonse, njira zowulukira ndege zikakumana ndi kuphulika kwa ndege ndi kupalasa njinga zotentha, komanso misewu ya m'tauni ikakumana ndi mabuleki oyimitsa ndi kupita ndi kutentha kwachilimwe kuposa 65°C, zosakaniza zowunjika bwino zimasweka, rut, kapena oxidize nthawi isanakwane. SMA imapereka zomwe zosakanizazo sizingathe: mafupa amiyala olumikizidwa, bitumen yosinthidwa ndi polima, ndi cellulose kapena mineral filler kuti atseke zonse m'malo. Koma zilibe kanthu ngati muli ndi vuto chomera cha asphalt SMA kuthekera kumachepa.

Taziwona patsamba: kapangidwe ka SMA kovomerezeka ndi labu, koma kukanidwa pamapazi chifukwa cha zomangira zosagwirizana kapena tsankho. Choyambitsa sichinali chophikira - chinali chomera. SMA imafuna kuwongolera kutentha kwambiri (± 2 ° C), dosing yolondola ya filler (± 0.3% ndi misa), ziro zoziziritsa kuzizira mumayendedwe osakanikirana, ndi homogenization yonse mkati mwa masekondi 45-osati 90. Zomera za ng'oma zokhazikika zimalimbana. Zomera za Counterflow nthawi zambiri zimatenthetsa binder. Ndipo makina amtundu wa batch opanda njira ziwiri zopangira phula ndi phula sangathe kubwerezabwereza.

Zomera za asphalt za Zibo Jixiang Machinery zimakumana ndi SMA molunjika-osati ngati kuganiza mozama, koma monga ntchito yopangira. Mndandanda wawo wa SjABP uli ndi zisankho zitatu zauinjiniya zomwe sizingakanjanitsidwe: Choyamba, chophatikizira chapamwamba kwambiri cha volumetric filler chokhala ndi chipata choyendetsedwa ndi servo komanso mayankho anthawi yeniyeni ya gravimetric-palibe masikelo a lamba, osasunthika. Chachiwiri, njira yoperekera phula ya mapaipi awiri: mzere umodzi wa binder yoyambira, umodzi wa chakudya chotentha chosinthidwa ndi polima, chilichonse chimakhala ndi kuyang'anira kutentha kodziyimira pawokha komanso kuwongolera kayendedwe kake. Chachitatu, chophatikizira chokhala ndi mitsinje iwiri yokhala ndi liwiro losinthika komanso masamba ang'onoang'ono - opangidwa kuti avale tinthu tating'onoting'ono tambirimbiri popanda kupaka binder kapena unyolo wonyozeka wa polima.

Kutumizidwa kwadziko lenileni kumatsimikizira izi. Mu 2023 kukweza misewu yayikulu m'chigawo cha Quang Nam ku Vietnam, kasitomala adasintha kuchoka ku ng'oma yaku Europe kupita ku batch unit ya Zibo Jixiang's SjABP-160. Kupanga kwa SMA kudalumpha kuchoka pa 72% pamagulu apadera (pa EN 13108-5) mpaka 98.6%. Chifukwa chiyani? Osati hardware yokha - logic yolamulira ndiyofunika. Mawonekedwe awo a PLC amatseka magawo ofunikira: kuwonjezera zodzaza kuyenera kuchitika * pambuyo * kutenthetsa kowuma koma * isanabadwe jekeseni phula; Kusakaniza nthawi kumayambiranso kokha pamene masensa onse amatsimikizira kutentha kwa chandamale ndi kuchuluka kwa torque. Palibe chowonjezera cha opareta chololedwa. Umu ndi momwe mumachotsera zolakwika zosinthika za anthu mu SMA.

Ena angatsutse kuti zomera za modular zimadzipereka kulimba chifukwa cha liwiro. Iwo akulondola-ngati chimango sichinapangidwe kuti chizigwira ntchito. Zibo Jixiang amagwiritsa ntchito chitsulo chodulidwa ndi laser, chochepetsera kupsinjika pansanja yawo yayikulu. Cholowa chilichonse chimabowoleredwa ndi CNC-chobowoleredwa-chosawotchedwa m'munda-kuteteza kulolerana molingana ndikukula kwamafuta. Tidayeza kutembenuka koyima pa SjABP-120 panthawi yopitilira maola 12 a SMA: 0.8 mm pa kutentha kwapamwamba (175 ° C), pansi pa 2.5 mm ISO 50001 poyambira kusakaniza kufanana. Kukhazikika kumeneko kumatanthawuza molunjika ku voids-in-mineral-aggregate (VMA) zomwe ndizofunikira kwambiri kuti SMA ikhale yolimba.

Mtengo sikuti umangotengera mtengo wa zomata. Matani a SMA osokonekera amawononga ndalama zambiri kuposa kukonzanso - kumayambitsa kuchedwa, kuwononga kuwonongeka, komanso kuwononga mbiri. Zomera za Zibo Jixiang zimadula zinyalala ndi kapangidwe kake: makina awo obwezeretsa fumbi otsekeka amatenganso> 92% ya chindapusa chodzaza, kuwabwezera mu hopper ya dosing. Kuwotcha kwawo kumasintha chiŵerengero chamafuta a mpweya mu nthawi yeniyeni kutengera kuwerengera kwa gasi wa flue O₂-kuchepetsa kugwiritsa ntchito mafuta ndi 11% motsutsana ndi machitidwe okhazikika popanda kupereka nsembe kutentha. Ndipo chifukwa ma subsystems onse ovuta - mita, kutumiza, kusakaniza - amamangidwa m'nyumba, zida zosinthira zimafika m'masiku 12, osati masabata 12. Makasitomala m'modzi ku Kazakhstan adanenanso kuti 94% yowonjezera pamiyezi 18 pakusintha kwa SMA, ndikuyimitsa kosakonzekera kopitilira mphindi 47.

Kusankha a chomera cha asphalt SMA Kuthetsa kumatanthauza kusankha komwe kutha. Simugulitsa kusinthasintha kwa liwiro. Simukuvomereza "kutseka mokwanira" pa VFA kapena kutsitsa. Mumamanga zomangamanga zomwe zimakhalapo - osati zomwe zimangokwaniritsa, koma zimapitilira zomwe zimayembekezeredwa pansi pa katundu weniweni. Makina a Zibo Jixiang samagulitsa mbewu za phula. Amapereka machitidwe obwerezabwereza a SMA-osinthidwa, otsimikiziridwa, ndi okonzekera zaka 20 zotsatira za magalimoto.
