Daamurka la beddelay waa in lagu daro isku-darka dibadda (wax-beddelayaasha) sida caagga, xabagta, polymers-ka molecular sare, budada caagga ah ee dhuuban ama buuxinta kale, ama la qaado tallaabooyin ay ka mid yihiin farsamaynta oksaydhka khafiifka ah ee daamurka si loo sameeyo isku dhafka asphalt ama daamurka Waxqabadka xidhaha asphalt waa la wanaajin karaa.
Waxaa jira laba hab oo lagu beddelo asphalt. Mid waa in la beddelo isku dhafka kiimikaad ee asphalt, midda kalena waa in la beddelo si siman loogu qaybiyo asphalt si loo sameeyo qaab-dhismeedka shabakad bannaan oo gaar ah.
elastomer-ka caaga ah iyo heerkulbeegga daamur la beddelay
Waxaa ka mid ah: caag dabiici ah oo la beddelay, daamur la beddelay oo SBS ah (kan ugu ballaaran loo isticmaalo), caag styrene-butadiene la beddelay, caag chloroprene oo la beddelay, caag butyl ah oo la beddelay asphalt (sida caagga ethylene propylene, caag nitrile, iwm.)
Oo ay ku jiraan: daamur la beddelay oo la beddelay, ethylene-vinyl acetate polymer daamur la beddelay, daamur la beddelay oo la beddelay, daamur la beddelay oo coumarin, resin epoxy la beddelay, asphalt α-olefin random polymer beddelka asphalt.
Daamur wax laga beddelay oo polymer la isku daray
Laba ama in ka badan oo polymers ah ayaa lagu daraa asphalt isku mar si wax looga beddelo daamurka. Labada ama in ka badan oo polymers ah oo halkan lagu sheegay waxay noqon karaan laba polymers oo kala duwan, ama waxay noqon karaan waxa loogu yeero polymer alloy oo hore loogu daray si loo sameeyo shabakad isku xiran oo polymer ah.
