Abstract
【解決手段】混合物は水とともに水和して機械加工可能なプラスター組成を形成し、スプレー可能なスラリーを調合する際に使用される。混合物は重量でおよそ80%からおよそ98%の硫酸カルシウム半水塩、前述のプラスター混合物を基板に接着するための重量でおよそ1%からおよそ5%の粘着性バインダ、及び重量でおよそ0.001%からおよそ10%の多糖体を含有する。混合物の重量に対しておよそ10%からおよそ50%の水を混合物に加えて、混合物をスラリーにする。
Description
このように、この分野においてスラリーの凝固化時間を安定化し、スプレー塗布された組成物を素早く機械加工可能な厚さにする方法が必要となる。またさらに、ほぼ一定した水需要量においてアルファ焼石膏に対してベータ焼石膏の濃度を上げる必要がある。これらの必要性が満たされた場合、スプレー可能で機械加工可能なプラスター生産物をより速く、より少ない廃棄物および/あるいはより低費用で製造することが可能になる。
水のプラスタータに対する割合が固定された場合、吸湿性効果はわずかな厚味増し作用をもたらす。このわずかな厚味増し化作用は特に垂直表面へのスプレー塗布機能を向上する。さらに、ポリ(エチレングリコール)は固有の潤滑特性を実証する。この特性は機械加工中の摩擦を最低限に抑えるため、機械加工中での内部バインダの集塊化を抑制する。
