Inkcazelo yemastic technology asphalt

Uphosa asphalt umxube eziphathekayo zizixhobo ezintsonkothileyo-edityanisiweyo esisetyenziswa ngokubanzi iinjongo zokwakha. Umahluko omkhulu ukusuka asphalt yemastic asphalt inkqubo eziphathekayo ukuze ukufakwa kwayo.

Production ngomxube

Ukubunjwa itela bumba iqulathe amacandelo efanayo njengoko ngenxa asphaltic eziphathekayo, kodwa ibathwana ezahlukeneyo nomkhombe. Awona macandelo aphambili umxube na otyhidiweyo igrabile, isanti, izimbiwa umgubo kunye ngetha. Kodwa ke izithako kanye ezi kuqamba eyahlukileyo kancinci. Sand kusetyenziswa imvelaphi zendalo okanye oluyeka yeliwa kwezimbiwa powder - Iveliswe ukusuka kakhulu rocks carbonate.

Ubungakanani ngebhitumene powder ngaphezulu kakhulu kunokuba abantu ngekhonkrithi asphaltic, nto leyo eyenza lwalo yeplastiki wabumba viscous. abenzi abaninzi kwimveliso umxube uphose asphalt mixture esetyenzisiweyo, nto leyo ngokuqinisekileyo kunciphisa iindleko inkqubo yokudala endleleni, kodwa nefuthe elibi iimpahla zazo.

iimpawu

Inzuzo ephambili yolu hlobo zokwaleka lugqityiwe ukumelana amanzi ngenxa yonke kunokuba isakhiwo aneentunja, ngaleyo ndlela kwande iyahlala xhaxhe ububanzi isicelo. Ngokuxhomekeke kwiimfuno lobuchwepheshe zemveliso yobomi yemastic itela up isiqingatha senkulungwane, ezinomphefumlo inkonzo kakhulu elide asphalt eziphathekayo.

Ukusetyenziswa kwimixube ezinjalo kuvumela ukwenza umphezulu indlela kakuhle ngakumbi nokunciphisa ububanzi ngaphandle kokulahlekelwa iipropati uphawu. Olu hlobo asphalt eziphathekayo kuye komelezwa wear iimpawu zibe nerusi kwaye ezikwaziyo yokungafani ixesha umonakalo ukudinwa, kwakunye ikwazi withstanding ezinkulu eqine deformation umlinganiswa. asphalt yemastic ukumelana ngakumbi yomonakalo zombane okanye ezinqunquthayo amavili igcwele, unako ukumelana ubushushu kakhulu nokuqhelana elide thermal. Akudingi ukusetyenziswa umxube uphawu, yaye ukutyabeka yokulungisa enokwenziwa ngexesha amaqondo aphantsi.

ukushiyeka

Noko ke, le ukutyabeka uneempawu ezimbi, eziquka iindleko zokuvelisa ophezulu ngenxa yokusetyenziswa eyandileyo izixa zamacandelo eninzi, kunye nemfuneko sokuqesha indlela elikwinqanaba ingqokelela siyiguqulela asphalt (ezizodwa thermo-ngabenzi kunye nezifudumezi). Ngaphezu koko, ngenxa isiqulatho eliphezulu asphalt yokuhlanganisa yokukwazi ubunzima izalathisi ngenxa apho kukho imfuneko yomsebenzi eyongezelelweyo kwi-compact black umaleko igrabile zixhonywe wamatye igada.

technology asphalt yemastic

Le nqubo lulodwa ezintsha. Ukuveliswa cast itela lwenziwa kwi izityalo asphalt ekhethekileyo izakhiwo bitumomesilnyh, ngabenzi efanayo eziphathekayo omkhulu, ngokutsho ubuchwepheshe, ezifana nokwenziwa asphalt eziqhelekileyo eziphathekayo. Lo mxube ogqityiweyo unalo lobushushu eliphezulu (200 C), nto leyo iya kuhlala injalo de ukusetyenziswa kwezinto ukulungiselela injongo yawo. Xa ezithutha asphalt engamanzi kufuneka rhoqo ukuluvusa umxube kwaye ukugcina ubushushu apho oomatshini ezizodwa ziye wadalwa - "Kocher", ezo thermo-ngabenzi.

isicelo

Siphose asphalt ikhonkrithi ezisetyenziselwa ukwakha emikhulu kunye Trace, indlela kunye imiphezulu ibhulorho kunye abadlulayo. Ukongeza, ngenxa kwiipropati viscous, isetyenziselwa amanzi okanye ustilaniya imigangatho kumagumbi. Ukuthandwa asphalt yemastic kubangelwe ukusetyenziswa bekhululekile xa lokulungiswa imingxuma yendlela kwixesha abandayo kwi ziingqele. Emva ukutyabeka ngokulula sisinde ukuya degrees 10 thabatha Wawuzalisa isithuba yona emhadini.

Kwakhona isicelo asphalt yemastic ukuba Ipeyinti yabahambi. Oku kukuvumela ukuba ugcine zonke iimpawu ezintle kwingoma kwaye ayinike ifomu kubuhle kunye nesakhiwo. Ngale wamatye akuthethi uhlumisa ingca, akukho iintanda. Ukutyabeka uyakwazi ukumelana zombini umthwalo ubunzima eliphezulu lobushushu drop. Nangona kunjalo, ukusetyenziswa kwimixube yamahlelo kwimveliso ukupheyiva Iizilebhu, kugcina kuphela zonke iipropati abangabaxhamli asphalt, kodwa kukwadala ezintsha. wamatye onjalo uzinzo eliphezulu thermal nobuhlobo esingqongileyo, ngokuba ubushushu tile ukufudumeza ngaphezu awuvumeli ukutyabeka ezabelwe elo carcinogens okusingqongileyo.

asphalt obuthululwayo kungaba lula kwaye zezikhali, kwaye usethe nje. Oku konga imali ukulungiswa. Ukusetyenziswa yemveliso ophezulu umgangatho asphalt yemastic ukuba ukupheyiva Iizilebhu iqinisekisa ubomi kwithala elide ukutyabeka, leyo, ngokungafaniyo ukusuka asphalt ukuya kwiminyaka eli-100. imixube uphose wamatye nguye kangangoko ukusetyenziswa kwiindawo zabo, ngenxa yoko kuxelwe inqanaba eliphezulu ezisemgangathweni kunye nobuhlobo lokusingqongileyo. Siphose asphalt ngenxa kuluhlu olubanzi iipropati luncedo kunye nokungabikho lentswelo ilungele imveliso ingxelo esecaleni.
