I-SMA-Ilitye leMastic Asphalt-ayisiyonto nje enye inkcazo ye-asphalt. Luphawu lokusebenza. Xa oohola bendlela bethwele izithuthi ezingama-30,000+ yonke imihla, xa iindlela zeenqwelo moya zeenqwelomoya zijongana nejet blast kunye nebhayisekile eshushu, kwaye xa izitalato zasedolophini zinyamezele ukunqandwa kwebraking kunye nobushushu basehlotyeni obungaphezu kwe-65°C, imixube eshinyeneyo ekumgangatho ophezulu iyaqhekeka, iruti, okanye i-oxidize ngaphambi kwexesha. I-SMA ihambisa oko loo mixube ayinakukwazi ukuyenza: i-skeleton yamatye edibeneyo, i-bitumen i-polymer-modified binder, kunye ne-cellulose okanye i-mineral filler ukuyivala yonke indawo. Kodwa akukho nanye kwezi zinto zibalulekileyo ukuba yakho isityalo se-asphalt SMA ubunakho buba mfutshane.

Siyibonile kwisiza: uyilo lomxube we-SMA oluvunywe ilebhu, kodwa lwaliwe kwipaver ngenxa yokungahambelani komxholo wesibophelelo okanye ulwahlulo oludityanisiweyo. Unobangela wengcambu wawungeyona iresiphi-yayisisityalo. I-SMA ifuna ukulawulwa kweqondo lokushisa elingqongqo (± 2 ° C), i-dosing ye-filler echanekileyo (± 0.3% ngobunzima), i-zero ebandayo edibeneyo kumjikelezo wokuxuba, kunye ne-homogenization epheleleyo ngaphakathi kwemizuzwana ye-45-kungekhona i-90. Izityalo zedrum eziqhelekileyo ziyazabalaza. Izityalo ezichasene ne-counterflow zihlala zitshisa kakhulu isibophelelo. Kwaye iinkqubo zohlobo lwebhetshi ngaphandle kweendlela ezimbini zokulinganisa iimitha zokuzalisa kunye nebhitumene ngokulula azinakubetha ukuphindaphinda.

Izityalo ze-asphalt ze-asphalt zikaZibo Jixiang zoomatshini zidibana ne-SMA entloko-kungekhona njengengcamango, kodwa njengomyalelo woyilo. Uchungechunge lwabo lwe-SjABP lubandakanya iindlela ezintathu zobunjineli ezingenakuxoxisana: Okokuqala, i-feeder ye-volumetric filler ene-high-precision ephezulu ene-servo-controlled gate kunye ne-real-time gravimetric feedback-akukho sikali sebhanti, akukho drift. Okwesibini, inkqubo yokuhanjiswa kwebhitumene ye-twin-pipe: umgca omnye we-binder base, enye ye-polymer-modified hot feed, nganye inokubeka iliso elizimeleyo lobushushu kunye nokulinganisa ukuhamba. Okwesithathu, i-double-shaft paddle mixer enesantya sokujikeleza esilungelelaniswayo kunye neeblade ezicandiweyo-eyilwe ukuba igqume yonke i-aggregate ye-particle yonke ngaphandle kwe-smearing binder okanye i-polymer chain chain.

Ukuthunyelwa kwehlabathi lokwenyani kuqinisekisa oko. Kuphuculo lohola we-2023 kwiPhondo leQuang Nam laseVietnam, umxhasi utshintshe ukusuka kwisixhobo sokwenza igubu saseYurophu ukuya kwiyunithi yebhetshi ye-Zibo Jixiang's SjABP-160. Imveliso ye-SMA yatsiba ukusuka kwi-72% kwiibhetshi ze-spec (nge-EN 13108-5) ukuya kwi-98.6%. Ngoba? Hayi nje i-hardware-ingqiqo yokulawula ibalulekile. Ujongano lwabo lwe-PLC lutshixa iiparamitha eziphambili: ukongezwa kwesihluzi kufuneka kwenzeke *emva* kokufudumeza okomileyo kodwa *phambi* kwenaliti yebhitumene; ixesha lokuxuba ukusetha kwakhona kuphela xa bonke abenzi boluvo kuqinisekisa temp ejoliswe kunye nomthwalo torque. Akukho gama libhalwe ngaphezulu lomsebenzisi livumelekileyo. Yiloo ndlela osusa ngayo iimpazamo zabantu kwi-SMA.

Abanye banokuphikisa ukuba izityalo zemodyuli zincama ukuqina ngesantya. Bachanekile-ukuba isakhelo asenzelwanga umthwalo oguqukayo. I-Zibo Jixiang isebenzisa i-laser-cut, i-stress-relieved structural steel kwinqaba yabo engundoqo. Idibeneyo nganye i-CNC-drilled and bolted-not welded in field-ukugcina ukunyamezela ukulungelelaniswa phantsi kokwandiswa kwe-thermal. Silinganise ukuphambuka okuthe nkqo kwi-SjABP-120 ngexesha eliqhubekayo le-SMA yeeyure ze-12: 0.8 mm kwi-peak temp (175 ° C), ngaphantsi kwe-2.5 mm ye-ISO 50001 yomgangatho wokuxuba okufanayo. Olo uzinzo luguqulela ngokuthe ngqo kwixabiso elihambelanayo le-voids-in-mineral-aggregate (VMA)-ibaluleke kakhulu kwi-SMA durability.

Iindleko azikho malunga nexabiso lesincamathelisi kuphela. Itoni ye-SMA engafanelekanga ixabisa ngaphezulu kokusebenza kwakhona-ibangela ukulibaziseka, ukonakala okuphekiweyo, kunye nomngcipheko wodumo. Izityalo zeZibo Jixiang zinqumle inkunkuma ngokuyila: inkqubo yazo yokubuyisela uthuli oluvaliweyo iphinda ithathe> i-92% yezohlwayo zokuzalisa, iphinde ibondle kwi-dosing hopper. Ukulawulwa kwabo kokushisa kulungelelanisa umlinganiselo we-air-fuel ngexesha langempela ngokusekelwe kwi-flue gas O₂ ukufundwa-ukunciphisa ukusetyenziswa kwe-fuel nge-11% ngokubhekiselele kwi-fixed-ratio systems ngaphandle kokubingelela izinga lokushisa. Kwaye ngenxa yokuba zonke ii-subsystems ezibaluleke kakhulu-imitha, ukuhanjiswa, ukuxuba-zakhelwe ngaphakathi endlwini, ii-spare parts zifika ngeentsuku ezili-12, kungekhona iiveki ezili-12. Omnye umxhasi eKazakhstan uxele i-94% yexesha elingaphezulu kweenyanga ezili-18 kwiishifti ze-SMA, kunye nokuvalwa okungacwangciswanga okungaphezulu kwemizuzu engama-47.

Ukukhetha i isityalo se-asphalt SMA isisombululo sithetha ukukhetha apho ulungelelwano luphela khona. Awuthengisi ukuhambelana kwesantya. Awumkeli "ukuvalwa ngokwaneleyo" kwi-VFA okanye i-draindown. Wakha iziseko ezingundoqo ezihlala-hayi nje ukuhlangabezana ne-spec, kodwa idlula ubulindelwe phantsi kwemithwalo yokwenyani. Oomatshini beZibo Jixiang abazithengisi izityalo ze-asphalt. Bazisa ukubulawa okuphindaphindiweyo kwe-SMA-ilinganisiwe, yaqinisekiswa, kwaye ilungele iminyaka elandelayo ye-20 yetrafikhi.
