一种Sc/ZSM-12分子筛材料的制备方法
摘要：
本发明公开了一种Sc/ZSM-12分子筛材料的制备方法，1.特征在于，所述Sc/ZSM-12分子筛材料的制备方法包括：步骤1、首先将30g硅溶胶和10g铝酸钠在超声波震荡下100℃油浴超声3h除杂；步骤2、将10ml四乙基溴化铵(TEABr)，10g硝酸钪，5ml 2mol/L氢氧化钠溶液在超声波震荡水浴100℃2h除杂；步骤3、将硅溶胶滴加到烧瓶中，然后滴加去100ml离子水，氢氧化钠溶液，以每分钟20滴速度滴加，并同时磁力搅拌油浴加热100℃3h；步骤4、将铝酸钠加到上述溶液中，然后在滴加模板剂四乙基溴化铵(TEABr)，以每分钟30滴速度滴加，在滴加同时进行磁力搅拌油浴加热100℃2h；步骤5、将硫酸锰溶解在去100ml离子水中，然后将硫酸锰水溶液加入到上述溶液中，在磁力搅拌油浴加热100℃3h制成凝胶液。
摘要（英）：

The invention discloses a decorative sound-absorbing door comprising a decorative door external plate, a sound-absorbing plate, a sound-absorbing external frame and a base plate. The door external plate is equipped with a decorative pattern; pyramid projections are evenly distributed on the surface of the sound-absorbing plate; and the sound-absorbing plate is made of molecular sieve material. With the pyramid projections evenly distributed on the surface of the sound-absorbing plate, sound wave refraction can be abated; the sound-absorbing plate is made of the molecular sieve material which is prepared via a especial technology, and sound absorbing coefficient can reach 0.96, so obvious sound-absorbing effect can be achieved for the whole door; and comprehensive sound absorbing coefficient can reach 0.99.
