濟南瀝青料在什么溫度下會發(fā)揮出好性能?

來源:http://drafti.cn/ 日期:2022-04-28
  瀝青料是什么?其實在我們的日常生活中經(jīng)常會接觸它,該材料會作為道路施工的主力進行使用,那么你知道濟南瀝青料在什么溫度下會發(fā)揮出好性能嗎?下面來了解一番吧。
  What is asphalt? In fact, in our daily life often contact with it, the material will be used as the main road construction, then you know jinan asphalt material at what temperature will play a good performance? Let's take a look.
  噴漆時要注意天氣和溫度的變化,原材料的比例一般會因氣候和環(huán)境的不同而發(fā)生變化。在適宜的溫度下,瀝青材料可以在很大程度上發(fā)揮其性能,大大提高使用壽命。
  When painting, pay attention to the change of weather and temperature. The proportion of raw materials will generally change due to the different climate and environment. At the right temperature, bituminous materials can exert their performance to a great extent and greatly improve their service life.
  瀝青材料的施工溫度要求常溫為15~25度。施工時環(huán)境溫度適中,溫度要求不低于5度,不高于35度。因為溫度太低,油漆容易凝固,涂漆時不均勻,容易結(jié)塊。
  The construction temperature of asphalt materials is required to be 15 ~ 25 degrees at normal temperature. The ambient temperature during construction is moderate. The temperature should be no less than 5 degrees Celsius and no higher than 35 degrees Celsius. Because the temperature is too low, the paint is easy to solidify, paint uneven, easy to agglomerate.
  此外,在澆注瀝青材料時,會聞到一股刺鼻的氣味,而且由于這種材料在高溫下很容易揮發(fā),這種揮發(fā)的氣味會有致癌的危險。但如果用量比較少,不會對人體造成傷害。但如果長時間聞到這種氣味,聞多了還是很危險的,甚至比苯還厲害。
  In addition, when pouring asphalt materials, there is a pungent smell, and because the material is prone to volatilization at high temperatures, the volatile smell can be carcinogenic. But in small amounts, they do no harm. But if you smell it over a long period of time, too much of it can be dangerous, even worse than benzene.
  此外,濟南瀝青料會對皮膚造成一定程度的傷害。如果長期處于含有瀝青的環(huán)境中,人的皮膚會出現(xiàn)粉刺或丘疹,嚴重時會引起皮膚潰瘍和化膿。因此,您在使用時需要采取預(yù)防措施,以免對自身安全造成威脅。
  In addition, Ji 'nan asphalt material will cause a certain degree of damage to the skin. If you are exposed to asphalt for a long time, your skin will have acne or pimples, which can cause skin ulcers and pus in serious cases. Therefore, you need to take precautions to avoid any threat to your own safety.
  總之還要知道,瀝青料使用溫度在零下時盡量不宜施工,以上便是我們給大家介紹的關(guān)于瀝青料的相關(guān)內(nèi)容,如果您有更多問題就來網(wǎng)站drafti.cn進行咨詢吧。
  In short, we should also know that asphalt should not be constructed as far as possible when the temperature is below zero. The above is the related content of asphalt that we introduce to you. If you have more problems, please come to the website drafti.cn for consultation.
