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.

　　想要更好的把嵌縫石膏用得好，用的少，用的精，聽我來詳細的講一下。

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

　　1、先要曉得嵌縫石膏：

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

　　嵌縫石膏由高強度精細的石膏粉為主，添加了一定量的緩凝劑保水劑，抗裂劑等多種助劑混制而成。具有粘結(jié)才能強，抗裂功用優(yōu)秀，運用時間長的等特征。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:

　　用于石膏制品之間，石膏板的接縫，線槽等部位的嵌縫，補平處置。特征：

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

　　單調(diào)較快，但可以做的很厚，干縮率很低，不會因過厚開裂。

　　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.

　　嵌縫石膏以添補石膏板縫為主，所以有更高的柔性需求，在強度上可以看出來。

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

　　粉刷石膏以厚抹灰為主，有保水性的需求，而強度方面較前者次之，但有收縮需求。

　　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.粉刷石膏和嵌縫石膏都屬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.

　　2.兩種石膏的不同之處在于：粉刷石膏適用于批刮墻面，除了要有滿足的粘結(jié)力，抗裂、填充性以外還要有大面積施工時的批刮順滑性（保水性）。嵌縫石膏是用來添補溝縫的，施工面積相對較小，不需求粉刷石膏的批刮順滑性，有滿足的粘結(jié)力、強度、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.出產(chǎn)這兩種石膏商品的配方是不一樣的......嵌縫石膏不舉薦大面找平。

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

　　緣由：嵌縫石膏由于骨料偏細，脆性強，做大面積找平可能會呈現(xiàn)部分開裂，起殼的情況。

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