Processing technology for improving moisture absorption and halogenation phenomena of magnesite fireproof door core plate
The invention discloses a processing technology for improving moisture absorption and halogenation phenomena of a magnesite fireproof door core plate, and relates to the technical field of fireproof door processing. The specific technology is as follows: 1) preparing composite porous powder from fly ash, diatomite and kaolin; 2) introducing magnesium chloride into the composite porous powder to obtain magnesium chloride-loaded particles; 3) carrying out hydrothermal reaction on titanium dioxide and lead nitrate to obtain a micron flaky filler; and 4) adding light calcined magnesia, the magnesium chloride-loaded particles, the micron sheet filler, the fly ash, polypropylene fibers, perlite, redispersible latex powder and an auxiliary agent into water, mixing, injecting the mixture into a mold after uniform mixing, carrying out curing molding, and carrying out natural curing. According to the process method provided by the invention, magnesium chloride molecules can be effectively prevented from diffusing and migrating to the surface of the core plate, and accumulation of magnesium chloride on the surface of the core plate is reduced, so that the phenomenon that the magnesite fireproof door core plate easily absorbs moisture and returns to halogen is improved, the quality of the magnesite fireproof door core plate is improved, and the service life is prolonged.
本发明公开了一种改善菱镁防火门芯板吸潮返卤现象的加工工艺，涉及防火门加工技术领域，具体工艺如下：1）利用粉煤灰、硅藻土和高岭土制得复合多孔粉末；2）将氯化镁引入到复合多孔粉末中，得到负载氯化镁颗粒；3）采用二氧化钛和硝酸铅经过水热反应得到微米片状填料；4）将轻烧氧化镁、负载氯化镁颗粒、微米片状填料、粉煤灰、聚丙烯纤维、珍珠岩、可再分散乳胶粉以及助剂加入到水中进行混合，待混匀后注入模具中固化成型，经过自然养护即可。本发明提供的工艺方法，可以有效的抑制氯化镁分子扩散迁移到芯板表面，减少芯板表面氯化镁的堆积，从而实现了改善菱镁防火门芯板易吸潮返卤的现象，提高了菱镁防火板芯板的品质以及使用寿命。
