Mineral powder ukwenziwa asphalt amamiksi

Mineral powder isetshenziswa njengoba ingxenye organic-compounds, kuhlanganise asphalt.

Izimpawu ndaba

Ngaphansi amaminerali powder kwakusho izinto okuyinto etholwe emva kwasani amadwala noma impuphu umkhakha izinsalela. Njengoba idokhumenti normalizing esetshenziswa SNIP futhi GOST. Mineral powder ihambisana nezidingo isimo RF ejwayelekile №52129-2003 «amaminerali powder for asphalt eziphathekako Izingxube organomineral."

Wenziwe kulandela indlela imishini yokusaha izingodo ukugaya: dolomite limestone, dolomite, namathempeli ngokhonkolo namatshe. Njengoba izinto zokusetshenziswa kusetshenziswe njengezigqila ezingewona ama-carbonate impahla eluhlaza kanye ezimbonini, ikakhulukazi impukane umlotha ezinhlotsheni zimboni.

Isebenzisa ezimbili izinhlobo powder: yasebenza futhi inactivated. Ukuze ukwahluka ezibonakalayo zize kuqala ukusebenzisa adjuvants ekhethekile. Ziyakwazi nenye surfactants ne itiyela. Kuye izakhiwo impahla eluhlaza esetshenziswa futhi ihlukaniswe yaba emagreyidini amabili:

• MP-1. It izimpushana edwaleni carbonate rocks bituminous.
• MP-2. Lokhu mass powder izinsalela phezu izitshalo zezimboni kanye non-carbonate amatshe.

kusebenze powder

Asphalt ingxube ukhonkolo uzoba ukusebenza okungcono uma izimpushana yayo abamelwe ziyasebenza. Yenza kube lula ngokwanele. Ngenxa yale njongo, a ukusebenza okuthiwa yenziwa nenye izimpushana ka surfactants futhi itiyela.

Ingqikithi yalo nqubo kanje. Ngo isinyathelo kwasani izinto zokusetshenziswa Activator kusetshenzwe. Phakathi izinhlayiya nepepper we impahla kanye amafomu Activator obuqinile. Ngakho, kwamanzi kuba izimpushana hydrophobic, futhi izinhlayiya ngabanye basebenzisane kangcono ne itiyela. Sokuqanjwa Imininingwane ingxube bituminous ikhethelwe kusebenze okungukuthi amaminerali powder, njengoba has a surface area esikhulu ethize (endaweni 4 ayizinkulungwane ^cm2 / g). Lona ingxube iyunifomu kakhulu yezingxenye kwengoma.

Asphalt mix ukhonkolo, okubandakanya amaminerali isebenze powder, has eziningi eziwusizo:

• I kwabantu lenyuka material.
• ukuthungwa Okuningi ngamandla.
• Ukumelana umswakama kanye frost.
• Okuthuthukisiwe ukumelana ngokuhlaziya.
• ukusetshenziswa uma ikhuluma ngebitume kuyehla 15%.
• ingxube Ukubeka wenziwa ezingeni lokushisa aphansi.

ukukhiqizwa indlela

ukukhiqizwa amaminerali powder senzeka ngezigaba eziningana. Luqala ngokunikela ukulungiselela izinto zokusetshenziswa kunesidingo. Indaba kokuqala womile endaweni omiswe izigubhu ezikhethekile. Uma -limestone amatshe buyimfanelo enamandla kakhulu, pre-kwasani roller noma ngesando izitshalo. Kwezinye izimo, lesi sinyathelo yeqiwe.

Ngesikhathi esifanayo kukhona ukulungiswa izinto isebenze. Incwadi uma ikhuluma ngebitume futhi surfactants kukhona eliwu izinga lokushisa lokusebenza. Ilungiselela ingxube kusebenze. Futhi isebenze omisiwe ingxube eluhlaza sathathwa ngo nenani kwesokudla futhi kuxutshwe in a stirrer gwedla. Kodwa Ungasebenzisa nezinye izinhlobo amadivaysi. Lapho ingxube kwaba kahle exubile, it is ithunyelwa apharathasi ukugaya ukugaya kuya fineness edingekayo. Ngemva kwalokho, kokuqendwa amaminerali powder ithunyelwa emgqonyeni isitoreji noma kuya ishede yokugcina.

Ukugcinwa Kwazo Ngenjongo ezokuthutha

Mineral powder elondolozwe ku hoppers noma silos. Kulezi zimo kubalulekile ukuqhuba nemicimbi ekhethekile, hhayi enikeza ikhekhe impahla. Lokhu kungaba aeration, ukudonsa nezinye izindlela zokwelapha. Lapho lokugoqa izigubhu ezincane (izikhwama) indaba egcinwe emafektri. Phakathi ukukhiqizwa powder is eyalo lo zokuthutha ngokuphelele ebiyelwe, auger. Ukuze zokuhamba endaweni ibhizinisi isetshenziswa womoya.

WezokuThutha powder ngaphandle ibhizinisi kumele ibe iloli usimende, nezinqola ezimboziwe (hoppers) iziqukathi. La masaka kumele kube ezincane nokupakisha multilayer iphepha noma plastic. Kulokhu, lo powder amaminerali is uthuthwa abavamile avaliwe zesitimela.
