怎么选择合适的挤塑板?
作者:admin 来源:本站 发布时间:2019-02-21 10:52:15 浏览次数:93
山东挤塑板经常运用在建筑结构内,起到良好的保温和防火效果.挤塑板的质量影响着保温效果,所以选购质量好的挤塑板就十分重要.
Shandong Extrusion board is often used in building structure, which has good thermal insulation and fire protection effect. The quality of Extrusion board affects the thermal insulation effect, so it is very important to choose a good quality extrusion board.
首先呢我们在选购挤塑板的时候,要先去看看它的保温级别.一般来说,用户需要选择B1级的挤塑板.它是近年普遍推广应用的新型建筑材料,这种利用废旧塑料变废为宝的新型环保材料,具备了相当卓越的性能.
First of all, when we choose extrusion board, we should first look at its insulation level. Generally speaking, users need to choose B1 extrusion board. It is a new building material widely used in recent years. This new environmental protection material, which uses waste plastics to turn waste into treasure, has quite excellent performance.
然后呢我们需要查看挤塑板的厚度,根据不同要求来选择不同厚度的挤塑板.通常,用户可以选择2-10公分厚的挤塑板.
Then we need to look at the thickness of the Extrusion board and choose different thickness of the Extrusion board according to different requirements. Usually, users can choose 2-10 cm thick extrusion board.
挤塑板和保温板两种完全不同的保温材料,硅酸盐保温板是一种无机保温材料,防火性能好,为A级材料,不燃型。但该材料缺陷较多,保温性能只有挤塑板的一半,材料密度较大,一般都在每立方200公斤以上,耐水性较差。挤塑板是一种有机保温材料,原材料为聚苯乙烯。保温性能很好,耐水性极好,但该材料防火性能一般,只能达到B1级难燃型。另外,挤塑板多用于屋面保温,用于墙体保温时,易出现开裂、脱落等质量问题。还有一种保温材料为聚苯板,是目前应用最广泛的一种墙体保温材料,保温性能稍差于挤塑板,防火性能为B1级,经济实惠,应用技术成熟,不易出现质量问题。

Extruded board and insulation board are two completely different thermal insulation materials. Silicate insulation board is an inorganic thermal insulation material with good fire resistance. It is grade A material and non-flammable. However, the material has many defects, the thermal insulation performance is only half of the extruded board, the material density is larger, generally more than 200 kilograms per cubic meter, and the water resistance is poor. Extruded board is an organic thermal insulation material, the raw material is polystyrene. The heat preservation performance is very good, water resistance is excellent, but the fire resistance of the material is general, can only reach B1 level of flame retardant. In addition, Extrusion board is mostly used for roof insulation, when used for wall insulation, cracking, falling off and other quality problems are easy to occur. Another kind of thermal insulation material is polyphenyl board, which is the most widely used wall thermal insulation material at present. Its thermal insulation performance is slightly worse than that of extruded board. Its fire protection performance is grade B1. It is economical and practical. Its application technology is mature and it is not easy to produce quality problems.

TDD保温装饰一体板中的XPS挤塑板和PUR聚氨酯保温板非常像,但他们的也是有差别的,首先容重:XPS容重32公斤,PUR容重可达38公斤,导热系数:XPS导热系数在0.035,PUR在0.033左右,抗燃性方面,PUR也比XPS要好,但,PUR 也有不好的地方,点燃的烟有毒,而且造价较高,外表做容易辨别的就是PUR质地较细,摸起来会有粉末状颗粒掉落。
XPS Extrusion board and PUR thermal insulation board in TDD thermal insulation and decoration integrated board are very similar, but they also have differences. First, the volume weight of XPS is 32 kilograms, the volume weight of PUR can reach 38 kilograms, the thermal conductivity: XPS thermal conductivity is 0.035, PUR is about 0.033, and the flame resistance of PUR is better than XPS, but PUR also has disadvantages, the smoke ignited is toxic, and the cost is higher. The appearance is easy to distinguish is that PUR texture is finer, feel will drop powder particles.
如果单从这一个数据来进行挑选,那么肯定效果就不太好,特别是外墙外保温上,目前很多人对这方面不太了解,现在我国制定的标准比较低,所以造成现在很多板材上都存在一定的滞后问题,而且外墙保温技术上也没有完全的掌握好,所以很多人对外墙保温材料的概念存在一定的错误理解或者片面理解。认为选择导热系数比较低的外保温材料是最好的,但是实际上这种选择可能导致整个工期设计和施工上都进行不下去,而且这个错误观念的引导也会导致企业错误的购买,导致使用实际的建筑保温技术上参差不齐。。
If we select from this data alone, then the positive effect is not very good, especially on external wall insulation. At present, many people don't know much about this aspect, and the standards formulated in our country are relatively low, so there are some lagging problems on many plates, and the external wall insulation technology is not fully mastered, so many people have external wall insulation materials. There are some misunderstandings or one-sided understandings of the concept. It is considered that it is the best choice to choose exterior insulation materials with low thermal conductivity, but in fact this choice may lead to the whole construction period design and construction can not go on, and the guidance of this misconception will also lead to the wrong purchase of enterprises, resulting in the use of actual building insulation technology is uneven.
