装修里的济南石膏粉到底是啥？别再和医用石膏搞混了！

　　What is Jinan gypsum powder in decoration? Don't confuse it with medical plaster anymore!

　　不少业主装修时都会像视频里那位朋友一样，看到师傅用的石膏粉就疑惑：“这不是骨折固定的石膏吗？怎么还能往墙上刮？”其实装修用的石膏粉和医用石膏虽有“亲戚关系”，但用途和加工方向完全不同。作为专业石膏粉生产厂家，今天就用通俗的语言科普：装修里的石膏粉到底是啥，又能发挥哪些关键作用，帮你彻底搞懂这款装修“基础神器”。

　　Many homeowners, like the friend in the video, are puzzled when they see the plaster powder used by the master during decoration: "Isn't this the plaster used for fracture fixation? How can it still be scraped against the wall?" In fact, although the plaster powder used for decoration is related to medical plaster, its purpose and processing direction are completely different. As a professional gypsum powder manufacturer, today we will use popular language to explain what gypsum powder in decoration is and what key roles it can play, helping you thoroughly understand this "basic artifact" of decoration.

　　先明确石膏粉的本质——它的核心成分是硫酸钙，天然石膏矿经过开采、研磨、煅烧等工艺加工后，就能变成不同用途的石膏粉。医用石膏和装修用石膏的原料基础相似，但加工工艺和添加成分有差异：医用石膏更侧重“快速固化、贴合人体”，而装修用石膏粉则针对“墙面适配性”优化，比如增加调节凝结时间、提升附着力的成分，让它能更好地服务于墙面装修。所以视频里师傅说“你这样理解（和医用石膏关联）也没毛病”，但两者的应用场景可是大不一样。

　　First, clarify the essence of gypsum powder - its core component is calcium sulfate. After natural gypsum ore is processed through mining, grinding, calcination and other processes, it can be turned into gypsum powder for different purposes. The raw material foundation of medical gypsum and decorative gypsum is similar, but there are differences in processing technology and added components: medical gypsum focuses more on "rapid curing and fitting to the human body", while decorative gypsum powder is optimized for "wall adaptability", such as adding components that adjust setting time and enhance adhesion, so that it can better serve wall decoration. So in the video, the master said, 'There's nothing wrong with your understanding (related to medical plaster),' but the application scenarios of the two are quite different.

　　装修中最常用的石膏粉就是视频里提到的“粉刷石膏”，它的核心作用是给墙面做“基层找平”——简单说就是把墙面凹凸不平的地方填平整，为后续批腻子、刷乳胶漆打下好底子。普通墙面找平可能用腻子就行，但遇到平整度要求高、需要厚涂的情况，粉刷石膏的优势就体现出来了：它的找平厚度常规能达到2公分，特殊配方的甚至能到3公分，不会像腻子那样厚涂后容易开裂、脱落。

　　The most commonly used gypsum powder in decoration is the "plastering gypsum" mentioned in the video. Its core function is to "level the base layer" of the wall - in simple terms, to fill in the uneven areas of the wall and lay a good foundation for subsequent putty and latex paint application. Ordinary wall leveling may be done with putty, but when it comes to situations that require high flatness and thick coating, the advantages of plastering are reflected: its leveling thickness can usually reach 2 centimeters, and special formulas can even reach 3 centimeters, without cracking or falling off easily after thick coating like putty.

　　尤其是那些对平整度和牢固度要求高的位置，更是离不开粉刷石膏。比如电视背景墙、沙发背景墙，后期要贴岩板、挂装饰画，墙面不平整会直接影响美观；木门洞口、窗口如果高低不平，会导致门框、窗框安装不严实，出现漏风、渗水问题；衣柜安装的墙面要是有误差，衣柜会和墙面有缝隙，既积灰又影响颜值。这些地方都得先用粉刷石膏仔细打底找平，把基础做扎实了，后续装修才能不出错。

　　Especially for positions that require high flatness and firmness, plastering gypsum is indispensable. For example, for TV background walls and sofa background walls, it is necessary to stick rock panels and hang decorative paintings in the later stage. Uneven wall surfaces will directly affect aesthetics; If the height of wooden door openings and windows is uneven, it can lead to loose installation of door and window frames, resulting in air and water leakage problems; If there is an error in the wall installation of the wardrobe, there will be gaps between the wardrobe and the wall, which will accumulate dust and affect the appearance. These places need to be carefully coated and leveled with plaster first, to make the foundation solid, and then the decoration can be carried out without any mistakes.

　　除了找平，石膏粉还能帮墙面“防开裂”，这也是视频里师傅提到的关键作用。装修时难免会遇到水电开槽、新旧墙体拼接的地方，这些部位是墙面开裂的“重灾区”。师傅们会在这些地方贴上网格布，再用石膏粉填充、找平，网格布能增强墙面的抗拉力，石膏粉则能和基层紧密结合，把这些“薄弱环节”加固好，最大程度避免后期墙面出现裂缝。

　　In addition to leveling, gypsum powder can also help prevent wall cracking, which is a key role mentioned by the master in the video. During decoration, it is inevitable to encounter areas such as water and electricity slotting, and the splicing of new and old walls, which are the "hardest hit areas" for wall cracking. Masters will stick mesh cloth in these areas, fill and level them with gypsum powder. Mesh cloth can enhance the tensile strength of the wall, while gypsum powder can tightly bond with the base layer to reinforce these "weak links" and minimize the occurrence of cracks on the wall in the later stage.

　　和传统的水泥砂浆相比，装修用的粉刷石膏还有两个明显优势：一是更细腻，刮涂后墙面基层更平整，后续批腻子时能省不少事，乳胶漆刷完也更光滑；二是硬度更高，干燥后能形成结实的基层，不容易因为碰撞、摩擦出现破损，让墙面更耐用。视频里师傅敢拍着胸脯保证“后期不开裂”，就是因为优质石膏粉的这些特性。

　　Compared with traditional cement mortar, gypsum used for decoration has two obvious advantages: first, it is finer and smoother, making the wall base smoother after scraping, saving a lot of trouble when applying putty later, and making the latex paint smoother after brushing; Secondly, it has higher hardness and can form a solid base layer after drying, which is less likely to be damaged due to collision or friction, making the wall more durable. In the video, the master dares to pat his chest to ensure that it will not crack in the later stage, because of these characteristics of high-quality gypsum powder.

　　厂家专业建议

　　Manufacturer's professional advice

　　作为生产厂家，提醒大家：选装修用石膏粉时，要优先选正规厂家的产品，注意看产品包装上的执行标准（比如粉刷石膏要符合JC/T 517-2017标准），避免买“三无产品”——劣质石膏粉可能含杂质多、凝结时间不稳定，不仅找平效果差，还可能后期开裂。另外，不同场景要选对应类型的石膏粉，比如找平用粉刷石膏，补小缝隙用嵌缝石膏，别混用才能发挥最好效果。

　　As a manufacturer, we would like to remind everyone that when choosing gypsum powder for decoration, it is important to prioritize products from reputable manufacturers and pay attention to the execution standards on the product packaging (such as meeting JC/T 517-2017 standards for plastering gypsum), to avoid buying "three no products" - low-quality gypsum powder may contain many impurities, have unstable setting time, not only have poor leveling effect, but may also crack later on. In addition, different types of gypsum powder should be selected for different scenarios, such as leveling with plastering gypsum and filling gaps with jointing gypsum. Do not mix them together to achieve the best effect.

　　结语

　　Conclusion

　　装修里的石膏粉，不是简单的“医用石膏平替”，而是墙面装修的“基础担当”——找平、加固、防开裂，每一个作用都关乎后期装修质量。搞懂它的本质和用途，才能在装修时监督施工、选对材料，避免像视频里那位业主一样因为误解闹笑话，也能让自家墙面更平整、更耐用。我们作为厂家，也会持续生产优质石膏粉，为大家的装修基础保驾护航，有任何疑问欢迎随时咨询！
