濟(jì)南石膏粉的制作要注意哪些?

石膏粉是一種廣泛應(yīng)用在建筑搅幅、藝術(shù)制作等領(lǐng)域的材料。它主要由石膏礦物和適量的助劑混合制成呼胚。在制作石膏粉的過程中茄唐,需要進(jìn)行碾磨、煅燒膳庵、冷卻辐芍、篩分等步驟。
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.
石膏礦物的選取
Selection of gypsum minerals
選擇好的石膏礦物作為原料是石膏粉制作的首要步驟描休。在選取石膏礦物時(shí)需要考慮其成分掷戚、質(zhì)地和純度。常用的石膏礦物有石膏石肥册、蒸發(fā)石膏猫郎、膨潤(rùn)土石膏等。其中严荷,石膏石是常用的原料矩修。
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
將選取的石膏礦物送入碾磨機(jī)中進(jìn)行碾磨處理,將塊狀的石膏礦物磨成細(xì)粉末。碾磨機(jī)的選用要考慮石膏礦物的硬度和韌性厅揍,一般使用球磨機(jī)或者離心磨機(jī)铡涣。
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.
篩分
screening
將碾磨好的石膏粉末進(jìn)行篩分處理,去除粉末中的雜質(zhì)和大顆粒弹惦。篩分后的石膏粉末需要達(dá)到一定的細(xì)度和均勻度要求否淤。
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.
煅燒
calcination
將篩分后的石膏粉末送入煅燒窯內(nèi)進(jìn)行煅燒處理。煅燒過程中棠隐,石膏粉末會(huì)逐漸變硬石抡,水分會(huì)被蒸發(fā)掉,同時(shí)石膏中的各種雜質(zhì)也會(huì)被分解和揮發(fā)宵荒。煅燒溫度一般在160℃到200℃之間汁雷,時(shí)間取決于石膏粉末的成分和燒結(jié)要求。
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.
冷卻
cooling
煅燒后的石膏塊需要進(jìn)行冷卻處理报咳,防止熱量對(duì)石膏粉末的影響侠讯。冷卻方式可以使用風(fēng)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
將冷卻后的石膏塊送入粉碎機(jī)中進(jìn)行二次研磨暑刃,將石膏塊研磨成粉末厢漩。這個(gè)過程中需要控制粉碎機(jī)的轉(zhuǎn)速和拍打次數(shù)。
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.
加入助劑
Adding additives
為了提高石膏粉末的質(zhì)量和性能岩臣,在粉末中適量加入一些助劑溜嗜,如凝結(jié)劑、流動(dòng)劑等庇启。這些助劑可以改變石膏粉末的物理性質(zhì)和化學(xué)性質(zhì)丢墅,提高石膏粉末的強(qiáng)度和流動(dòng)性。
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.
包裝
packing
將加入助劑后的石膏粉末裝入袋內(nèi)盛媚,密封保存莽简。在包裝時(shí)需要注意石膏粉末的濕度和容量,以避免粉末受潮和過度壓縮撤忆。
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.
