Core Properties ntawm Waterproof Mortar
High Impermeability: Lub permeability coefficient ntawm waterproof mortar tuaj yeem ncav cuag li 1 × 10⁻¹² m/s (ib GB 23440-2009 standard), ho qis dua li qub mortar (1 × 10⁻⁶ m / s), zoo thaiv dej nkag. Qhov no yog ua tiav los ntawm kev tsim cov yeeb yaj kiab polymer lossis cov khoom siv hydrophobic thaiv cov hlab capillary pores. Piv txwv li, ntxiv silicone-based waterproofing agents tuaj yeem txo qhov porosity ntau dua 60%.
High Durability: Nrog ntau dua los yog sib npaug rau 50 khov -thaw cycles (JGJ/T 70-2009) thiab nthuav tawm 30% -50% txhim kho kev tawg, ua rau nws haum rau cov cheeb tsam uas muaj qhov kub thiab txias hloov pauv lossis cov av noo siab.
Superior Bonding Strength: Adhesion zog rau substrates Ntau dua los yog sib npaug rau 1.0MPa (piv rau 0.5MPa rau cov mortar zoo tib yam), tshwj xeeb tshaj yog tsim rau cov pobzeb sib txuas lossis kho cov haujlwm.
Qhov txawv ntawm Ordinary Mortar
Khoom siv:
Waterproof Mortar: Cement + Quartz Sand + Waterproofing Agents (xws li, acrylic esters, nkag mus rau cov ntaub ntawv crystalline).
Ordinary Mortar: Cement + Xuab zeb nkaus xwb, tsis muaj kev hloov kho ntxiv.
