  • Rubber polymer modified asphalt production process
    고무폴리머 개질아스팔트 생산공정

    outline

    RPMA (Rubber polymer modified asphalt) has better viscoelasticity, flexibility, shearing strength and adhesiveness than general asphalt. It is a process of producing products using long-term physico-chemical reaction with high performance special mixer at high temperature by adding fine waste tire rubber powder (below 80 mesh) and small amount of polymer after activating general asphalt with special catalyst.

  • Blown asphalt production process
     블로운 아스팔트 생산공정

    outline

    Asphalt production processing by modifying property such as penetration and softening point through dehydrogenation and polymerization reaction after oxidation of asphalt with oxygen by blowing compressed air into straight run asphalt.

  • Emulsified asphalt production process
     블로운 아스팔트 생산공정

    outline

    Asphalt produced by adding emulsifier and stabilizer to asphalt and to disperse asphalt into particle type. It is used for road pavement and emulsified asphalt is divided into cation and anion. We produce cation emulsified asphalt with excellent stability.

  • Solvent process
     블로운 아스팔트 생산공정

    outline

    With low sulfur treated naphtha after advanced hydrogen added desulfurization process, it is processed naphtha by re-distilling considering the features and usage of solvent. It is a process of producing solvent for road, adhesive, rubber solvent, cleaning agent and paint thinner.

  • Wax process
     블로운 아스팔트 생산공정

    outline

    It is a process of producing treated wax by removing oil and low melting point wax in slack wax. It is a sweating and deoiling process and white clay process removing wax impurity and improving color by melting slack wax into sweating machine, coagulating into solid through cooling and increasing temperature gradually

  • Merox process
     블로운 아스팔트 생산공정

    outline

    It is a process of removing Mercaptan(R-SH) and H2 S and purifying into soft odor in the raw material oil by introducing UOP Merox Process technolo
