Abstract
Description
予め水和させたTEOSとエタノールを3:1の重量比で混合し、シリカゾル(シリカゾル内のシリカ含量4重量%)2040mlを製造した。
前記実施例1の1)、2)及び3)でガラス繊維に含浸または噴射するシリカゾルの比率を下記表1に記載されたところと同一にしたことを除き、実施例1と同様の方法でシリカエアロゲルブランケットを製造した。
予め水和させたTEOSとエタノールを3:1の重量比で混合してシリカゾル(シリカゾル内のシリカ含量4重量%)2040mlを製造し、ここに不透明化剤TiO24gを分散させた。
前記実施例及び比較例で製造した各シリカエアロゲルブランケットを12cm×12cmになるように切断してサンプルを製造した後、振動条件を18Hz/6hrsにして振動による重量減少率を測定し、その結果を下記表1に示した。
表1で示すように、実施例の重量減少率が比較例に比べて顕著に減少されたことが確認できた。これを介して実施例のシリカエアロゲルブランケットの粉塵発生量が比較例に比べて顕著に少ないことが分かり、これはシリカエアロゲルブランケットの表面に不透明化剤が露出されていないことによるものであることが予想できた。
前記実施例及び比較例で製造した各シリカエアロゲルブランケットをNETZSCH社のHFM436装備を用いて常温での熱伝導度を測定し、その結果を下記表1に示した。
前記実施例及び比較例で製造した各シリカエアロゲルブランケットを12cm×12cmになるように切断して製造したサンプルを6時間の間600℃のSiCプレートと密着させた後、裏面温度を測定して、その結果を表1に示した。
