  在建筑、艺术、医疗等多个领域,石膏粉以其独特的性能扮演着重要角色。这种看似普通的白色粉末,实则蕴含着丰富的多样性。了解石膏粉的分类及特性,能帮助我们更好地选择和使用这种材料。

  Gypsum powder plays an important role in various fields such as architecture, art, and medicine due to its unique properties. This seemingly ordinary white powder actually contains rich diversity. Understanding the classification and characteristics of gypsum powder can help us better choose and use this material.

  石膏粉的“家族谱系”

  The 'family lineage' of gypsum powder

  石膏粉的分类方式多样,如同一个庞大的家族,有着不同的分支和谱系。

  The classification of gypsum powder is diverse, like a large family with different branches and lineages.

  按“出身”分类:根据原料来源,石膏粉可分为磷石膏粉、脱硫石膏粉、柠檬酸石膏粉和氟石膏粉等。这些名称反映了石膏粉的“出身”,例如磷石膏粉主要来源于磷化工产业产生的副产品,而脱硫石膏粉则是燃煤电厂脱硫过程的产物。

  Classified by "background": According to the source of raw materials, gypsum powder can be divided into phosphogypsum powder, desulfurization gypsum powder, citric acid gypsum powder, and fluorogypsum powder. These names reflect the origin of gypsum powder, for example, phosphogypsum powder mainly comes from by-products generated by the phosphorus chemical industry, while desulfurization gypsum powder is a product of the desulfurization process in coal-fired power plants.

  按“肤色”分类:石膏粉也可根据颜色分为红石膏粉、黄石膏粉、绿石膏粉、青石膏粉、白石膏粉、蓝石膏粉、彩色石膏粉等。颜色的差异可能源于原料中的杂质或添加的颜料。

  Classified by "skin color": Gypsum powder can also be divided into red gypsum powder, yellow stone gypsum powder, green gypsum powder, bluestone gypsum powder, white gypsum powder, blue gypsum powder, colored gypsum powder, etc. The difference in color may be due to impurities in the raw materials or added pigments.

  按“体质”分类:从物理特征来看,石膏粉又有白云质石膏粉、粘土质石膏粉、绿泥石石膏粉、雪花石膏粉、滑石石膏粉、含砂质石膏粉和纤维石膏粉等之分。这些名称描述了石膏粉的矿物组成、纹理和结构特征。

  According to physical characteristics, gypsum powder can be classified into white cloud gypsum powder, clay gypsum powder, chlorite gypsum powder, snowflake gypsum powder, talc gypsum powder, sand containing gypsum powder, and fiber gypsum powder. These names describe the mineral composition, texture, and structural characteristics of gypsum powder.

  按“职业”分类:根据用途,石膏粉可分为建材用石膏粉、化工用石膏粉、模具用石膏粉、食品用石膏粉和铸造用石膏粉等。不同“职业”的石膏粉,在性能要求上也有所侧重。

  Classified by occupation: Gypsum powder can be divided into building materials gypsum powder, chemical gypsum powder, mold gypsum powder, food gypsum powder, and casting gypsum powder according to their use. Gypsum powder from different "professions" also have different emphasis on performance requirements.

  石膏粉的“素质评估”

  Quality assessment of gypsum powder

  面对琳琅满目的石膏粉,如何判断其优劣?可以从以下几个方面进行“素质评估”:

  How to judge the quality of a dazzling array of gypsum powder? Quality assessment can be conducted from the following aspects:

  “颜值”观察:外观是判断石膏粉质量的第一道关卡。白度高的石膏粉,通常细度目数高,质量较好。反之,发灰发黑、含有黑色杂质的石膏粉,质量可能较差。

  Appearance observation: Appearance is the first level to judge the quality of gypsum powder. Gypsum powder with high whiteness usually has a high fineness mesh and good quality. On the contrary, gypsum powder that appears grayish black and contains black impurities may have poor quality.

  “手感”体验:用手搓捻石膏粉,可以感受其细腻程度。手感细腻的石膏粉,细度细,质量较好;而手感发沙粗糙的石膏粉,细度糙,质量可能较差。

  Texture experience: Rubbing and twisting gypsum powder by hand can feel its delicacy. Gypsum powder with delicate texture, fine fineness, and good quality; However, gypsum powder with a rough and sandy texture may have poor quality due to its coarse fineness.

  “内在”检测:通过测定石膏粉的结晶水含量,可以判断其炒制工艺是否合格。结晶水含量在5%~5.5%之间为佳。含量过低,说明石膏粉过烧,注模时凝结时间可能过长甚至不凝固;含量过高,则说明石膏粉欠火或受潮,注模时凝结时间可能过短。

  Internal testing: By measuring the crystalline water content of gypsum powder, it is possible to determine whether its roasting process is qualified. The optimal content of crystal water is between 5% and 5.5%. If the content is too low, it indicates that the gypsum powder is burnt too much, and the setting time may be too long or even not set during injection molding; If the content is too high, it indicates that the gypsum powder is undercooked or damp, and the setting time during injection molding may be too short.

  “时效”测试:凝结时间是石膏粉的重要性能指标。初凝时间不小于6分钟,终凝时间不大于25分钟,为适宜的凝结时间。初凝时间过短或终凝时间过长,都可能影响生产使用。

  Time effectiveness test: The setting time is an important performance indicator of gypsum powder. The initial setting time should not be less than 6 minutes, and the final setting time should not exceed 25 minutes, which is the appropriate setting time. Short initial setting time or long final setting time may affect production and use.
