挤塑板新料与旧料的区别!

挤塑板新料与旧料的区别你了解吗?不了解的话就来看看小编的文章吧!希望对您今后的生活中有所帮助。
Do you know the difference between new and old materials of extruded sheet? If you don't understand, let's look at Xiaobian's article. I hope it will help you in your future life.
目前市场上普遍采用的保温板是挤塑板(XPS板),现在市场上流通的挤塑板有两种:一种是采用新原料制作的原生料挤塑板,还有一种是采用废旧塑料回收后制造的再生料挤塑板,由于原生料挤塑板的价格很高而且制造合格挤塑板的生产设备非常昂贵,目前我国仅在上海、天津,成都等地有少量工厂有这种设备,在川内仅固迪建材公司及另一家公司有这种设备,生产原生料高端挤塑板,其它商家都生产的是价格便宜的再生料挤塑板,所以内地绝大部分建筑物采用的挤塑板都是价格较便宜的再生料挤塑板,再生料挤塑板有两个致命的缺点,这两个致命缺点就必然给建筑带来重大火灾隐患。
At present, Extrusion board (XPS board) is widely used in the market. There are two kinds of Extrusion board in circulation: one is raw material extrusion board made from new raw materials, the other is recycled material extrusion board made from recycled waste plastics. Because the price of raw material extrusion board is very high and the production equipment of qualified Extrusion board is very expensive, at present, only two kinds of Extrusion board are in circulation in our country. In Shanghai, Tianjin, Chengdu and other places, a small number of factories have such equipment. In Sichuan, only Gudi Building Material Company and another company have such equipment to produce high-end Extrusion board of raw materials. Other businesses produce cheap Recycled Extrusion board, so most buildings in the mainland Use Recycled Extrusion board which is cheaper. There are two Recycled Extrusion board. A fatal shortcoming, these two fatal shortcomings will inevitably bring major fire hazards to the building.
首先,再生料挤塑板的生产工艺是将原料加热后挤塑成型,所以,保温板中非常重要的添加剂阻燃剂在加工过程中很容易挥发不宜留存,有些生产厂商为了节省成本甚至根本不添加阻燃剂,结果这类保温板就很容易被点燃引发火灾。

First of all, the production process of recycled material extrusion board is to heat the raw materials and extrude them. Therefore, the very important additive flame retardant in the insulation board is easy to volatilize and should not be retained in the process of processing. In order to save cost, some manufacturers even do not add flame retardant at all, as a result, this kind of insulation board is easy to ignite and cause fire.

其次,由于再生料挤塑板的物理性能很差,使用两年以后就会出现挤塑板四周向外翘起即所谓翘边现象,翘边的挤塑板连接处就会出现开裂,使易燃保温板裸露在建筑物表面,这时,一旦有明火点燃,保温板就会燃烧并蔓延造成重大火灾。
Secondly, due to the poor physical properties of Recycled Extrusion board, after two years of use, the so-called warping phenomenon will occur around the extrusion board, the joint of the warping Extrusion board will crack, making the flammable insulation board exposed on the surface of the building. At this time, once an open fire ignites, the insulation board will burn and spread, causing major fires.
再次,再生料挤塑板因原材料反复回收,导致板子色泽较差,因此大部分厂家都采用添加颜料的方式将板子变为另一种颜色,目的是掩盖再生料的本色,所以这种板子一般气味较大,刺鼻难闻,对人体有害;而原生料板子,本色为白色,色泽均匀,无气味,因此使用原生料挤塑板,更环保,更健康。
Thirdly, the recycled material extruded board is recycled repeatedly, which leads to poor color of the board, so most manufacturers use the way of adding pigments to change the board into another color, in order to cover up the original color of the recycled material, so the board generally has a bigger odor, unpleasant smell, harmful to human body; and the original material board, which is white, uniform color, odorless, so that the original material board is made of white, uniform color and odorless. It is more environmentally friendly and healthier to use raw material extrusion board.
按理说,所有建筑材料在施工前都有必要的监理和检查,但我国现行的质检都是送检方式,就是说,质检部门只对商家送去检验的产品负责检验,至于商家真正出售的商品是否是送检商品则没有任何监督。
It is reasonable to say that all building materials have necessary supervision and inspection before construction, but the current quality inspection in our country is the inspection mode, that is to say, the quality inspection department is only responsible for the inspection of the products sent by the merchants, and there is no supervision as to whether the merchants really sell the goods sent for inspection.
