墻面抹灰找平是石膏粉非常重要的用途之一。粉刷石膏（又稱抹灰石膏）可以代替傳統水泥砂漿進行室內墻面找平。它易于抹面，與基底的黏結力較強，可適用于各類墻體的抹面，面層致密光滑、不開裂、不起灰、硬度高。抹灰石膏還具有呼吸調濕、粘結力強、不開裂、施工方便等優點。輕質抹灰石膏可用于墻面輕質找平，石膏膩子或面層抹灰石膏可用于涂料層的精找平。

Wall plastering and leveling is one of the most important uses of gypsum powder. Gypsum plastering (also known as plaster gypsum) can replace traditional cement mortar for indoor wall leveling. It is easy to plaster, has strong adhesion with the substrate, and can be used for plastering various types of walls. The surface layer is dense, smooth, non cracking, non dusting, and has high hardness. Gypsum plastering also has the advantages of breathable moisture regulation, strong adhesion, no cracking, and easy construction. Lightweight plastering gypsum can be used for lightweight leveling of walls, while gypsum putty or surface plastering gypsum can be used for precise leveling of coating layers.

嵌縫填孔是石膏粉的另一重要用途。嵌縫石膏適用于填充石膏板縫隙、孔洞、溝槽等。它還可以用于陰陽角條的粘接，以及石膏板、木板、墻體的局部修補找平。嵌縫膏的初凝時間一般為40至60分鐘，終凝時間約120分鐘。

Jointing and filling holes is another important use of gypsum powder. Jointing gypsum is suitable for filling gaps, holes, grooves, etc. in gypsum boards. It can also be used for bonding internal and external corner strips, as well as for local repair and leveling of gypsum boards, wooden boards, and walls. The initial setting time of sealant is generally 40 to 60 minutes, and the final setting time is about 120 minutes.

石膏制品是石膏粉應用的大宗領域。紙面石膏板以建筑石膏為主要原料，摻入適量纖維材料、緩凝劑等作為芯材，以紙板作為增強保護材料，經攪拌、成型、切割、烘干等工序制成。此外，石膏粉還可用于生產石膏砌塊、石膏線條、粉筆等。

Gypsum products are a major field for the application of gypsum powder. Paper faced gypsum board is mainly made of building gypsum as the main raw material, mixed with appropriate amounts of fiber materials, retarders, etc. as the core material, and reinforced with cardboard as the protective material. It is made through processes such as mixing, forming, cutting, and drying. In addition, gypsum powder can also be used to produce gypsum blocks, gypsum lines, chalk, etc.

石膏粉與膩子粉的區別

The difference between gypsum powder and putty powder

很多人分不清石膏粉和膩子粉，其實兩者差異顯著。

Many people cannot distinguish between gypsum powder and putty powder, but the difference between the two is significant.

石膏粉主要是嵌縫、填補孔洞、陰陽角的修直，顆粒較為粗糙，凝結后較堅硬、不易打磨，凝結速度快。膩子粉主要是打底用，凝結速度慢，凝結后質地較軟，用砂紙打磨容易。

Gypsum powder is mainly used for joint filling, hole filling, and straightening of internal and external corners. The particles are relatively rough, and after setting, they are hard and difficult to polish, with a fast setting speed. Putty powder is mainly used as a base, with a slow setting speed and a soft texture after setting, making it easy to polish with sandpaper.

石膏粉一般是高強石膏粉，主要成分就是石膏，是很多其他建筑材料的添加劑，不能單獨使用。而膩子粉是成品膩子，直接兌水攪拌就可以施工。

Gypsum powder is generally high-strength gypsum powder, mainly composed of gypsum, which is an additive for many other building materials and cannot be used alone. And putty powder is finished putty, which can be directly mixed with water for construction.

石膏材料的獨特優勢

The unique advantages of gypsum materials

石膏及其制品具有質量輕、強度高、防火、隔熱、防潮、吸聲、形體飽滿、線條清晰、表面光滑細膩、裝飾效果好等特點。它是一種綠色快捷節能的建筑材料，是傳統抹灰材料的理想替代品。自動調節室內溫濕度、防火隔音隔熱等特性，使石膏材料在現代綠色建筑中越來越受到青睞。從嵌縫填孔到墻面找平，從石膏板到裝飾線條，石膏粉以其“多面手”的特質，在建筑與裝修的每一個角落默默發揮著不可替代的作用。

Gypsum and its products have the characteristics of light weight, high strength, fire resistance, thermal insulation, moisture resistance, sound absorption, full shape, clear lines, smooth and delicate surface, and good decorative effect. It is a green, efficient and energy-saving building material, and an ideal alternative to traditional plastering materials. The automatic adjustment of indoor temperature and humidity, as well as the characteristics of fire prevention, sound insulation, and heat insulation, have made gypsum materials increasingly popular in modern green buildings. From joint filling and hole filling to wall leveling, from gypsum board to decorative lines, gypsum powder plays an irreplaceable role in every corner of construction and decoration with its versatile nature.
