石膏粉怎么调配及使用注意事项

来源: 日期:2022-11-08 发布人:juyehe

在室内装修过程中,石膏粉起着非常重要的作用,主要用来砌墙体,勾缝,墙面找平等,还有一种彩色石膏粉还可以起到装饰作用,成本比较低。下面来讲讲济南石膏粉怎么调配及使用注意事项。
In the process of interior decoration, gypsum powder plays a very important role. It is mainly used for building walls, pointing and leveling walls. There is also a kind of colored gypsum powder that can also play a decorative role, with low cost. Now let's talk about how to mix and use Jinan gypsum powder.
石膏粉怎么调配
How to mix gypsum powder
1、硬度高的石膏粉调配方法:只需石膏粉和水,石膏粉与水的比例为100:28,将按比例调和即可。
1. Preparation method of gypsum powder with high hardness: only gypsum powder and water are needed, and the proportion of gypsum powder and water is 100:28, which can be mixed according to the proportion.
2、先加入水,其次再加入石膏粉,切记这点很重要,若先加石膏粉在加水的话,是很难将两者调配均匀的,石膏的硬度与搅拌的均匀程度是成正比的,搅拌越均匀,牢度越高。
2. It is important to add water first and then gypsum powder. If gypsum powder is added first and then water is added, it is difficult to mix them evenly. The hardness of gypsum is proportional to the uniformity of mixing. The more uniform the mixing, the higher the fastness.
3、凝固时间的掌握。凝固时间主要与加水量有关系,次之与搅拌时间、浇铸容器、温度、湿度有关系。水、石膏粉混合比,水越多石膏凝结时间越长,石膏密度越低、牢度越低,水越少凝结时间越短、密度越大、牢度越高,具体需根据使用需求来控制。
3. Mastery of solidification time. The setting time is mainly related to the amount of water added, followed by the mixing time, casting container, temperature and humidity. The mixing ratio of water and gypsum powder: the more water, the longer the setting time of gypsum, the lower the density and fastness of gypsum, the less water, the shorter the setting time, the greater the density and the higher the fastness, which shall be controlled according to the use requirements.
4、乳白胶添加剂的石膏调配:乳白胶能增加石膏的牢固度,乳白胶的添加会使石膏粉凝固时间延长,乳白胶用的越多凝固时间越长,添加乳白胶(较多)凝固后石膏表面比较细腻的感觉,上色不容易被石膏吸收,颜料只会停在石膏表面。制作粗糙表面、需要石膏自然吸收颜料的时候要注意,是否添加乳白胶是会影响效果。
4. Gypsum preparation of opal glue additive: opal glue can increase the firmness of gypsum. The addition of opal glue will prolong the setting time of gypsum powder. The more opal glue is used, the longer the setting time will be. After the addition of opal glue (more), the gypsum surface will feel more delicate. The color cannot be easily absorbed by gypsum, and the pigment will only stop on the gypsum surface. When making rough surfaces and requiring gypsum to naturally absorb pigments, attention should be paid to whether or not to add opal glue will affect the effect.

石膏粉使用注意事项
Precautions for use of gypsum powder
1、施工前应先行确定底材的垂直度与平整度。
1. The verticality and flatness of the substrate shall be determined before construction.
2、切忌将超过使用时间的灰浆加水混合后再用。
2. It is forbidden to mix the mortar that has exceeded the service time with water before reuse.
3、搅拌好的腻子粉浆应在1~2h内用完(视配方而定)。
3. The mixed putty mortar shall be used up within 1-2 hours (depending on the formula).
4、宜在1-2d内打磨。
4. It should be polished within 1-2d.
5、基面用水泥膏压光的情况下,建议使用界面处理剂或界面腻子、弹性腻子。白色石膏粉是我们较为广见的石膏材料,广泛用于装修、制模、雕塑等多类领域。好的白色石膏粉细目高,硬度好。有的还添加了少许碳酸钙,达到了坚硬的效果。
5. When the base surface is polished with cement paste, it is recommended to use interface treatment agent or interface putty and elastic putty. White gypsum powder is a widely seen gypsum material, which is widely used in decoration, mold making, sculpture and other fields. Good white gypsum powder has high fineness and hardness. Some also added a little calcium carbonate to achieve a hard effect.
6、在装饰中石膏粉通常用来做底层处理的,比方填平缝隙、阴阳角调直、毛坯房墙面腻子找对等。石膏的粘接度好,不易发生掉落表象,在用来进行墙面找平常,通常并不是直接运用石膏粉的,里边也会加入滑石粉,不然施工会不太方便了。
6. Gypsum powder is usually used for the bottom treatment in decoration, such as filling the gap, straightening the internal and external corners, and matching the putty on the wall of the blank room. Gypsum has good adhesion and is not easy to fall off. It is usually not directly used for walls. Talcum powder will also be added inside, otherwise the construction will be inconvenient.
