裝修里的濟南石膏粉到底是啥？別再和醫用石膏搞混了！

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

　　不少業主裝修時都會像視頻里那位朋友一樣，看到師傅用的石膏粉就疑惑：“這不是骨折固定的石膏嗎？怎么還能往墻上刮？”其實裝修用的石膏粉和醫用石膏雖有“親戚關系”，但用途和加工方向完全不同。作為專業石膏粉生產廠家，今天就用通俗的語言科普：裝修里的石膏粉到底是啥，又能發揮哪些關鍵作用，幫你徹底搞懂這款裝修“基礎神器”。

　　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.

　　先明確石膏粉的本質——它的核心成分是硫酸鈣，天然石膏礦經過開采、研磨、煅燒等工藝加工后，就能變成不同用途的石膏粉。醫用石膏和裝修用石膏的原料基礎相似，但加工工藝和添加成分有差異：醫用石膏更側重“快速固化、貼合人體”，而裝修用石膏粉則針對“墻面適配性”優化，比如增加調節凝結時間、提升附著力的成分，讓它能更好地服務于墻面裝修。所以視頻里師傅說“你這樣理解（和醫用石膏關聯）也沒毛病”，但兩者的應用場景可是大不一樣。

　　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.

　　裝修中最常用的石膏粉就是視頻里提到的“粉刷石膏”，它的核心作用是給墻面做“基層找平”——簡單說就是把墻面凹凸不平的地方填平整，為后續批膩子、刷乳膠漆打下好底子。普通墻面找平可能用膩子就行，但遇到平整度要求高、需要厚涂的情況，粉刷石膏的優勢就體現出來了：它的找平厚度常規能達到2公分，特殊配方的甚至能到3公分，不會像膩子那樣厚涂后容易開裂、脫落。

　　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.

　　尤其是那些對平整度和牢固度要求高的位置，更是離不開粉刷石膏。比如電視背景墻、沙發背景墻，后期要貼巖板、掛裝飾畫，墻面不平整會直接影響美觀；木門洞口、窗口如果高低不平，會導致門框、窗框安裝不嚴實，出現漏風、滲水問題；衣柜安裝的墻面要是有誤差，衣柜會和墻面有縫隙，既積灰又影響顏值。這些地方都得先用粉刷石膏仔細打底找平，把基礎做扎實了，后續裝修才能不出錯。

　　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，石膏粉還能幫墻面“防開裂”，這也是視頻里師傅提到的關鍵作用。裝修時難免會遇到水電開槽、新舊墻體拼接的地方，這些部位是墻面開裂的“重災區”。師傅們會在這些地方貼上網格布，再用石膏粉填充、找平，網格布能增強墻面的抗拉力，石膏粉則能和基層緊密結合，把這些“薄弱環節”加固好，最大程度避免后期墻面出現裂縫。

　　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.

　　和傳統的水泥砂漿相比，裝修用的粉刷石膏還有兩個明顯優勢：一是更細膩，刮涂后墻面基層更平整，后續批膩子時能省不少事，乳膠漆刷完也更光滑；二是硬度更高，干燥后能形成結實的基層，不容易因為碰撞、摩擦出現破損，讓墻面更耐用。視頻里師傅敢拍著胸脯保證“后期不開裂”，就是因為優質石膏粉的這些特性。

　　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.

　　廠家專業建議

　　Manufacturer's professional advice

　　作為生產廠家，提醒大家：選裝修用石膏粉時，要優先選正規廠家的產品，注意看產品包裝上的執行標準（比如粉刷石膏要符合JC/T 517-2017標準），避免買“三無產品”——劣質石膏粉可能含雜質多、凝結時間不穩定，不僅找平效果差，還可能后期開裂。另外，不同場景要選對應類型的石膏粉，比如找平用粉刷石膏，補小縫隙用嵌縫石膏，別混用才能發揮最好效果。

　　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.
