濟(jì)南巖棉泡沫板在保溫性能上的介紹

發(fā)布時(shí)間:2021-01-29 來源:http://m.95fjrc.com/

近幾年,隨著房地產(chǎn)行業(yè)的迅猛發(fā)展,保溫材料也隨之得到了發(fā)展,而巖棉板泡沫板作為一種常見的保溫材料被大家所熟知,但是很多朋友只是聽過巖棉板,卻對它一無所知,今天就由小編來跟大家簡單介紹一下它吧。

In recent years, with the rapid development of the real estate industry, the insulation materials have been developed. The foam board of rock wool board is known as a common insulation material. But many friends just listen to the rock wool board, but absolutely ignorant of it. Today, let's introduce it briefly to you.

1.巖棉板原料的主要成份是巖棉

  1. The main ingredient of rock wool board is rock wool

2.巖棉是由高分子合成樹脂(聚合物)為主要成份,滲入各種輔助料或添加劑,在特定溫度,壓力下,具有可塑性和流動性,可被模塑成一定形狀,且在一定條件下保持形狀不變的材料.

2. Rock wool is a kind of material which is mainly composed of high molecular synthetic resin (polymer), infiltrated with various auxiliary materials or additives, has plasticity and fluidity under specific temperature and pressure, and can be molded into a certain shape and keep the shape unchanged under certain conditions

3.聚合物:指聚合過程所產(chǎn)生的純材料或稱聚合材料.無論天然樹脂還是合成樹脂均屬高分子合聚物,簡稱高聚物.

3. Polymer: refers to the pure material or polymer material produced in the polymerization process. Both natural resin and synthetic resin belong to polymer, referred to as polymer

4.巖棉板對電,熱,聲具有良好絕緣性:電絕緣性,耐電弧性,保溫,隔聲,吸音,吸振,消聲性能高.

4. Rock wool board has good insulation to electricity, heat and sound: electric insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption and noise elimination

巖棉板原材料大部是從一些油類中提煉出來的,熟悉的部分PC料是從石油中提煉出來的, PC料在燒的時(shí)候有一股汽油味;ABS是從煤炭中提煉出來的, ABS在燒完滅掉的時(shí)候會呈煙灰狀;POM是從天然氣提煉出來的, POM在燒完的時(shí)候會有一股非常臭的瓦斯味.

Most of the raw materials of rock wool board are extracted from some oils, and some familiar PC materials are extracted from petroleum. PC materials have a smell of gasoline when burned; ABS is extracted from coal, and ABS will be ash when burned out; POM is extracted from natural gas, and POM will have a very smelly smell of gas when burned out
