Nrog rau kev nrawm nrawm ntawm nroog loj thiab kev tsim kho kev lag luam, kev sib txuas ntawm cov nroog thiab nroog, nroog thiab thaj chaw nyob deb nroog, thiab thaj chaw nyob deb nroog thiab thaj chaw nyob deb nroog tau ze dua. Cov chaw tsim cov xim pleev xim qhia tau hais tias txoj kev kos xim xim yog ib qho kev kos npe zoo tib yam siv rau asphalt pavement thiab cement pavement los coj thiab tswj kev tsheb. Txij li cov cim txoj kev yuav tsum tau tiv taus cua thiab lub hnub thiab qhov cuam tshuam thiab hnav ntawm lub tsheb, cov cim yuav tsum tau ua kom ntev.
txoj kev kos cim durability
(1) Hnav tsis kam. Cov chaw tsim tshuaj pleev xim kos npe tau qhia tias kev nce qib ntawm lub tsheb yog nyob ntawm qhov kev sib txhuam ntawm cov log thiab hauv av, thiab qhov kev sib txhuam no muaj qhov yuav tsum tau ua ntawm cov cim. Txoj kev hauv peb lub tebchaws yog qhov nyuaj. Txoj kev uas muaj kev puas tsuaj nyuaj, kev taug kev ntawm cov hlau log, thiab cov xuab zeb thiab slag ntawm txoj kev nto tag nrho muaj qhov xav tau siab ntawm kev hnav tsis kam ntawm txoj kev cim.
For wear resistance, my country's standard requires a weight loss of Less than or equal to 50mg at 200 rpm/1kg, while the Japanese standard JLS requires a weight loss of 100 rpm/1kg Less than or equal to 200mg. Of course, it suffices that the visibility of the abrasion resistance can be ensured within the specified range and within the specified time period.
(2) Weather resistance. The marking coating manufacturer introduced that thermoplastic coatings need to have excellent weather resistance. Combined with my country's vast territory, the climatic diversity of the east and west, the hot in the south and the cold in the north, and the characteristics of the road surface, the ratio of the raw materials of the coating can be adjusted to adapt to different climatic conditions, and it can be used for construction in different seasons. The durability should correspond to the expected value of the marking time. For example, the road marking is set to be applied once every 2 years, and the best marking paint should peel off when it reaches about 2 years, or after a simple Clear the roadbed without traces, so as to avoid the old line affecting the new marking line to guide the traffic flow, or consuming a lot of man-hours for clearing.
