Vietnam Umuhanda Usanzwe Umuhanda uranga irangi (yujuje ibyangombwa 8791: 2011) Ibikoresho bishyushye, birambye byashyizwe ku gishije cyo mu turere dushyuha muri Vietnam Igizwe na sinthetike resives (urugero, c5 petroleum resin), Titanium dioxyde (for-yera yubusa, ihabwa amabuye y'agaciro, amasaro yubusa, arashyuha kugeza 180-220 ° arakomera mu minota 1-3 akonje. Ibyiza byingenzi birimo ubuzima burebure bwa serivisi (2-5), igitangaza gikomeye kuri asfalt / beto, na retroreplation, no kwisubiraho mumihanda minini yinzira nyabagendwa, imihanda yo mumijyi, hamwe na zone yinganda muri Vietnam
Ibipimo bikomeye byo kwipimisha kuri TCVN 8791: 2011:
Ingingo yoroshye: ≥100 ° C (Mubisanzwe 105-115 ° C) Kurwanya ubushyuhe
Kuma Kuma: Iminota Yiminota (nta kabuza
Ikirahure
Kurwanya Abrosion: ≤200 MG Igihombo cya JM-100 Ibizamini, Gukira Kuramba munsi yumuhanda
Amazi / Kurwanya Alkali: Nta gukuramo cyangwa gufatanya nyuma yisaha 24 kwibiza mumazi cyangwa calcium hydroxide
Imbaraga zo Guhunga: ≥12 MPA (urugero, ibicuruzwa bya Bole bigera ku 26. Kwemeza ubushobozi bwo gutwara imitwaro
Kurwanya SKD: ≥45 BPN (nimero ya pendulum y'Abongereza) kugirango irinde kunyerera
Ibiti: ≥0.70 kuri umweru, ≥0.50 kumuhondo (kugaragara kumanywa)
Igenzura ryinyongera ritwikiriye ubushyuhe (nta gutesha agaciro kuri 200 ° C kumasaha 4) hamwe nubwumvikane bwibidukikije (amajwi make, imiterere yubusa). Ibi bipimo byerekana umutekano, kuramba, no kubahiriza amahame yumuhanda wa Vietnam, kugabanya kubungabunga kenshi mu biti bitoroshye.
