Seamless gypsum is not new to most people and knows what to do, but it is rare to use seamless gypsum reasonably. The popularization of seamless gypsum is mainly recommended by oil workers for leveling.

　　想要更好的把嵌缝石膏用得好，用的少，用的精，听我来详细的讲一下。

　　Want to better use seam gypsum well, use less, use the essence, listen to me to elaborate.

　　1、先要晓得嵌缝石膏：

　　1. First of all, we should know that seam gypsum:

　　嵌缝石膏由高强度精细的石膏粉为主，添加了一定量的缓凝剂保水剂，抗裂剂等多种助剂混制而成。具有粘结才能强，抗裂功用优秀，运用时间长的等特征。2、用途：

　　Seamed gypsum is mainly made of high strength and fine gypsum powder, with a certain amount of retarder, water retaining agent, crack resistance agent and other additives. It has the characteristics of strong bonding ability, excellent anti-cracking function and long application time. 2. Purpose:

　　用于石膏制品之间，石膏板的接缝，线槽等部位的嵌缝，补平处置。特征：

　　It is used for filling seams between gypsum products, joints of gypsum board, thread grooves and other parts. Features:

　　单调较快，但可以做的很厚，干缩率很低，不会因过厚开裂。

　　It's monotonous and fast, but it can be made very thick, the shrinkage rate is very low, and it won't crack because of too thick.

　　嵌缝石膏以添补石膏板缝为主，所以有更高的柔性需求，在强度上可以看出来。

　　Seamed gypsum is mainly made up of plasterboard joints, so it has a higher demand for flexibility, which can be seen from the strength.

　　粉刷石膏以厚抹灰为主，有保水性的需求，而强度方面较前者次之，但有收缩需求。

　　The plastering gypsum is mainly made of thick plastering, which has the requirement of water retention, followed by the former in strength, but has the requirement of shrinkage.

　　1.粉刷石膏和嵌缝石膏都属于建筑工程型石膏的制品。

　　1. Plaster gypsum and seamless gypsum belong to the products of construction engineering gypsum.

　　2.两种石膏的不同之处在于：粉刷石膏适用于批刮墙面，除了要有满足的粘结力，抗裂、填充性以外还要有大面积施工时的批刮顺滑性（保水性）。嵌缝石膏是用来添补沟缝的，施工面积相对较小，不需求粉刷石膏的批刮顺滑性，有满足的粘结力、强度、抗裂就行了。

　　2. The difference between the two kinds of gypsum is that whitewash gypsum is suitable for batch scraping wall. Besides satisfying bonding force, crack resistance and filling ability, it also has batch scraping smoothness (water retention) in large-scale construction. Seamed gypsum is used to fill ditch joints. Its construction area is relatively small. It does not need batch scraping smoothness of plastering gypsum. It has satisfied bonding force, strength and crack resistance.

　　3.出产这两种石膏商品的配方是不一样的......嵌缝石膏不举荐大面找平。

　　3. The formulation of producing these two kinds of gypsum commodities is different... Seamed gypsum does not recommend large surface leveling.

　　缘由：嵌缝石膏由于骨料偏细，脆性强，做大面积找平可能会呈现部分开裂，起壳的情况。

　　Cause: Because of the finer aggregate and the stronger brittleness of the seamed gypsum, large area leveling may present partial cracking and shelling.
