Description
ここで、セラミックス粉末は、製膜原液中約10〜77.5重量％、好ましくは約68.5〜77.5重量％となる割合で高充填して用いられる。これ以下の充填濃度では焼結体が得られず、一方これ以上の充填濃度では相対的に高分子物質の割合が少なくなり、複合膜の形成が困難となる。 Here, the ceramic powder is used by being highly filled in a ratio of about 10 to 77.5 % by weight, preferably about 68.5 to 77.5 % by weight in the film forming stock solution. When the filling concentration is lower than this, a sintered body cannot be obtained. On the other hand, when the filling concentration is higher than this, the proportion of the polymer substance is relatively reduced, and it becomes difficult to form a composite film.
実施例１
珪素化タングステン粉末(日本新金属製品；平均粒子径3.9μm)790g(製膜原液中77.45重量％)、ポリスルホン(UCC社製品P-1700)60g(同5.88重量％)およびジメチルホルムアミド170g(同16.66重量％)の混合物からなる製膜原液を、外径3.5mm、内径1.5mm、内管側外径1.1mmの二重環状ノズルを用いて、乾湿式紡糸を行った。
Example 1
790 g of tungsten silicide powder (Japanese new metal product; average particle size 3.9 μm) (77.45% by weight in the stock solution ), 60 g of polysulfone (UCC product P-1700) (5.88% by weight) and 170 g of dimethylformamide (16.66) The film-forming stock solution consisting of a mixture (by weight%) was dry and wet-spun using a double annular nozzle having an outer diameter of 3.5 mm, an inner diameter of 1.5 mm, and an inner tube-side outer diameter of 1.1 mm.
実施例２
珪素化モリブデン粉末(日本新金属製品；平均粒子径3.3μm)500g(製膜原液中68.49重量％)、ポリスルホン(P-1700)60g(同8.22重量％)およびジメチルホルムアミド170g(同23.29重量％)の混合物からなる製膜原液を、外径3.5mm、内径1.5mm、内管側外径1.1mmの二重環状ノズルを用いて、乾湿式紡糸を行った。
Example 2
Molybdenum silicide powder (Japan new metal product; average particle size 3.3μm) 500g (68.49% by weight in the film forming stock solution) , polysulfone (P-1700) 60g (8.22% by weight) and dimethylformamide 170g (23.29% by weight) The film-forming stock solution composed of the above mixture was subjected to dry and wet spinning using a double annular nozzle having an outer diameter of 3.5 mm, an inner diameter of 1.5 mm, and an inner tube side outer diameter of 1.1 mm.
