Mineral powder yekugadzirwa kweasphalt mitsva

Mineral powder inoshandiswa seimwe yemasanganiswa ehurumende, kusanganisira asphalt konkire.

Mamiriro ezvinhu

Maminerari powder ndeyezvinhu zvinowanikwa mushure mekugadzira matombo kana zvigadziri zveupfu zvemabhizimusi. Sezvinyorwa zvekusimudzira, SNIP neGOST zvinoshandiswa. Mineral powder inosangana nezvinodiwa nehurumende yehurumende yeRussian Federation Nha. 52129-2003 "Mineral powder yeAsphalt-concrete uye inorganical mixtures".

Iko kunogadzirwa nekukuya zvinotevera dombo rakaoma: chimestone yeodominised, dolomite, limestone. Sezvimwe zvigadzirwa, kwete-carbonate zvishandiso uye zvigadzirwa zvemabhiza zvinoshandiswa, kunyanya kupisa madota mumhando dzakasiyana-siyana dzekugadzirwa.

Mhando mbiri dzehupfu dzinoshandiswa: dzinoshandiswa uye hadzina kushandiswa. Mhando dzakasiyana dzekushandisa zvinhu zvinoshandiswa kwekutanga yezvinyorwa. Iko musanganiswa wevasfosfactants ane bitumen. Zvichienderana nezvinhu uye zvishandiswa zvakashandiswa, zvinyorwa zvakakamurwa kuva mativi maviri:

• MP-1. Aya ndiwo mapfupa kubva ku carbonate matombo uye matombo.
• MP-2. Ichi chiyero chemafuro eupupuri mumashamba emagetsi uye kwete-carbonate matombo.

Kushanda kwepoda

Sanganiswa yeAsphalt-konkrete ichave yakanakisisa kana zvidimbu zvinosanganiswa mumagadzirirwo ayo zvinoshandiswa. Zviri nyore kuita izvi. Nokuda kwechikonzero ichi, izvo zvinonzi kushandiswa kwepudders zvinogadziriswa nemusanganiswa wevashambadziri uye bitumen.

Chinokosha chekuita izvi ndotevera. Pachitambo chekupwanya, zvigadzirwa zvinoshandiswa nemushanduri. Pakati pezvakapwanyika zvinyorwa zvemashoko uye zvinoshandiswa, zvinosimba zvakasimba. Nokudaro, pamusoro pepudders inova hydrophobic, uye iyo michina inobatanidza zviri nani nebhitumini. Pamusoro pehuwandu hwekusanganiswa kweasphalt-concrete , mineral powder inosarudzwa kuti iite, sezvo ine nzvimbo yakakura yepamusoro (munharaunda ye 4,000 cm ² / g). Ichi ndicho chikamu chinonyanya kukanganiswa chevhangeri.

Asphalt-concrete musanganiswa, unosanganisira yakagadzirwa nemafuta, ane zvakakosha:

• Kuwedzera kwehuwandu hwezvinhu.
• Zvimwe zvinogara zvakagadzikana.
• Kurwisana kwekunaya uye chando.
• Kuvandudza kushorwa kwekuputika.
• Kushandiswa kwebhitumini kunoderedzwa ne15%.
• Iyo musanganiswa yakaiswa pachitsiko chepasi.

Nzira yekuwana

Iko kugadzirwa kwemineral powder kunowanikwa mumatanho akawanda. Zvose zvinotanga nekugadzirira kwezvinhu zvakakosha zvishandiso. Nyaya yekutanga yakaomeswa mukugadzirwa kwakanakira ngoma. Kana ikemineone inopwanyika mabwe ane simba rakakwirira, inopfuura kupera kwekutanga kunogadzika kana kuisa nyundo. Mune zvimwe zviitiko, danho iri rinobhururuka.

Panguva imwecheteyo, kugadzirira kwekubvumira zvinhu kunoitika. Bhitumini nevanoshambadzira zvinopisa kuti vashandise kutonhora. Kugadzirira musanganiswa wekuita. Iyo yakaomeswa yakasvibirira uye iyo inoshandiswa inosanganiswa inotorwa muhuwandu hwakaenzana uye inosanganiswa mu lobed stirrers. Asi mamwe maitiro ezvigadzirwa anogona kushandiswa. Apo musanganiswa wacho wakavhenganiswa zvakanaka, unotumirwa kunhengo yekukuya yekukuya kune zvakakosha. Mushure mokunge, iyo yakagadzirwa yakagadzirwa mineral powder inotumirwa kubhasi rekusachengetedza kana nzvimbo yekuchengetedza.

Kuchengetedza uye kutakura

Mineral powder inochengetwa mumabheji kana kuchengetedza silos. Muzviitiko izvi, zvakakosha kuti nguva nenguva iite zviyero zvakasiyana izvo zvisingabvumi kuti mashoko ave keke. Izvi zvinogona kuva aeration, kuputa uye dzimwe nzira dzokugadzira. Kana uchinge uine zviduku zviduku (mabhegi), zvinhu zvakachengetwa mumabhuku ekuchengetera. Penguva yekugadzira, iyo pfupa inotakurwa kuburikidza nemagetsi, conveyors uye screw conveyors zvakakwana zvakapoteredzwa nezvivharo zvinodzivirira. Nekufambisa kunharaunda yebazi, pneumotransport inoshandiswa.

Kutakura kwepoda kunze kwebhizimusi kunokosha mumaketari emotokari, mabote akavharwa (bunkers), zvidha. Sacks of small packing inofanira kunge yakagadzirwa nemapuranga akawanda kana kuti polyethylene. Muchiitiko ichi, iyo mineral powder inotakuriswa mumatokari akavharwa.
