济南石膏粉的制作要注意哪些?

来源:http://djinzi.com 日期:2023-12-23 发布人:

石膏粉是一种广泛应用在建筑、艺术制作等领域的材料。它主要由石膏矿物和适量的助剂混合制成。在制作石膏粉的过程中,需要进行碾磨、煅烧、冷却、筛分等步骤。

每日彩票Gypsum powder is a widely used material in fields such as architecture and artistic production. It is mainly made by mixing gypsum minerals with an appropriate amount of additives. In the process of producing gypsum powder, steps such as grinding, calcination, cooling, and screening are required.

石膏矿物的选取

每日彩票Selection of gypsum minerals

每日彩票选择好的石膏矿物作为原料是石膏粉制作的首要步骤。在选取石膏矿物时需要考虑其成分、质地和纯度。常用的石膏矿物有石膏石、蒸发石膏、膨润土石膏等。其中,石膏石是常用的原料。

每日彩票Choosing good gypsum minerals as raw materials is the primary step in the production of gypsum powder. When selecting gypsum minerals, it is necessary to consider their composition, texture, and purity. Common gypsum minerals include gypsum stone, evaporated gypsum, bentonite gypsum, etc. Among them, gypsum stone is a commonly used raw material.

碾磨

Grinding

将选取的石膏矿物送入碾磨机中进行碾磨处理,将块状的石膏矿物磨成细粉末。碾磨机的选用要考虑石膏矿物的硬度和韧性,一般使用球磨机或者离心磨机。

每日彩票Send the selected gypsum minerals into a grinding mill for grinding treatment, and grind the block like gypsum minerals into fine powder. The selection of grinding machines should consider the hardness and toughness of gypsum minerals, usually using ball mills or centrifugal mills.

筛分

screening

每日彩票将碾磨好的石膏粉末进行筛分处理,去除粉末中的杂质和大颗粒。筛分后的石膏粉末需要达到一定的细度和均匀度要求。

每日彩票Screen and treat the ground gypsum powder to remove impurities and large particles from the powder. The screened gypsum powder needs to meet certain requirements for fineness and uniformity.

煅烧

每日彩票calcination

每日彩票将筛分后的石膏粉末送入煅烧窑内进行煅烧处理。煅烧过程中,石膏粉末会逐渐变硬,水分会被蒸发掉,同时石膏中的各种杂质也会被分解和挥发。煅烧温度一般在160℃到200℃之间,时间取决于石膏粉末的成分和烧结要求。

每日彩票Send the screened gypsum powder into the calcination kiln for calcination treatment. During the calcination process, gypsum powder will gradually harden, water will be evaporated, and various impurities in gypsum will also be decomposed and evaporated. The calcination temperature is generally between 160 ℃ and 200 ℃, and the time depends on the composition of gypsum powder and sintering requirements.

冷却

cooling

煅烧后的石膏块需要进行冷却处理,防止热量对石膏粉末的影响。冷却方式可以使用风冷或者水冷方式。

The calcined gypsum blocks need to be cooled to prevent the influence of heat on the gypsum powder. The cooling method can be air cooling or water cooling.

粉碎

smash

每日彩票将冷却后的石膏块送入粉碎机中进行二次研磨,将石膏块研磨成粉末。这个过程中需要控制粉碎机的转速和拍打次数。

Send the cooled gypsum block into the crusher for secondary grinding, and grind the gypsum block into powder. During this process, it is necessary to control the speed and number of beats of the crusher.

加入助剂

Adding additives

每日彩票为了提高石膏粉末的质量和性能,在粉末中适量加入一些助剂,如凝结剂、流动剂等。这些助剂可以改变石膏粉末的物理性质和化学性质,提高石膏粉末的强度和流动性。

每日彩票In order to improve the quality and performance of gypsum powder, some additives such as coagulants and flowers are added in an appropriate amount to the powder. These additives can change the physical and chemical properties of gypsum powder, improve its strength and flowability.

包装

packing

每日彩票将加入助剂后的石膏粉末装入袋内,密封保存。在包装时需要注意石膏粉末的湿度和容量,以避免粉末受潮和过度压缩。

每日彩票Put the gypsum powder added with additives into a bag and seal it for storage. When packaging, it is necessary to pay attention to the humidity and capacity of gypsum powder to avoid moisture and excessive compression of the powder.
