外觀上辨別石膏粉質量的方法！

來源：http://m.wavc.cn 日期：2019-01-16 發布人：

對于從外觀上辨別石膏粉質量的方法有哪些?下面由濟南石膏粉的人員介紹一下：

　　What are the methods to distinguish the quality of gypsum powder from its appearance? The following is introduced by the professional staff of Jinan gypsum powder:

　　通過外觀上觀察和手感可初步判斷石膏粉質量的優劣。觀察就是看外觀包裝袋質量情況和石膏粉的外觀顏色，手感就是用手搓一搓石膏粉的糙細程度(細度)。

　　The quality of gypsum powder can be preliminarily judged by its appearance observation and feel. Observation is to see the quality of the external packaging bags and the appearance of the color of gypsum powder, feel is to rub the roughness (fineness) of gypsum powder by hand.

　　(1)若包裝塑料編織袋的材質質量差、松軟強度低、做工粗糙、編織稀疏(單位面積內的經緯數目不達標)、顏色發灰綠黑色、內部沒有防潮塑料袋、出現撒料現象、三無產品或外觀標識(種類名稱、生產廠家、商標、重量、聯系方式等)不齊全的石膏粉則很大可能不符合質量標準、檔次質量差，質量穩定性也不能保證。反之，那些包裝塑料編織袋用材好、做工精致、顏色發白、強度高、編織經緯密集、內部有防潮塑料袋、封口嚴密、外觀印刷清晰、標識齊全、不撒料的石膏粉一般質量較好、檔次高，質量有保證。一般使用這種包裝袋的石裔粉白度高、細度細。若石膏粉是質量上乘的、高附加值的高強度石膏粉、特種石膏粉(如母模石裔粉、原模石膏粉或樹脂石膏粉)，其價格很高,是普通石膏粉的3～9倍。

　　(1) If the material quality of plastic woven bags is poor, the soft strength is low, the workmanship is rough, the knitting is sparse (the number of longitudes and wefts per unit area is not up to the standard), the color is greyish green and black, there is no moisture-proof plastic bags inside, there is no spraying phenomenon, and there is no product or appearance marking (category name, manufacturer, trademark, weight, contact mode, etc.) incomplete plaster powder may be very large. It meets the quality standard and the quality of grade is poor, and the quality stability can not be guaranteed. On the contrary, those packaging plastic woven bags have good materials, exquisite workmanship, white color, high strength, dense weaving warp and weft, moisture-proof plastic bags inside, tight seals, clear appearance, complete markings, and no spraying of gypsum powder are generally of good quality, high grade and guaranteed quality. Generally, this kind of packing bag has high whiteness and fine fineness. If gypsum powder is of high quality and high added value, high strength gypsum powder and special gypsum powder (such as mother model gypsum powder, prototype gypsum powder or resin gypsum powder), its price is high, which is 3-9 times higher than that of ordinary gypsum powder.

　　(2)外觀上看，白度高的石膏粉細度目數高，質量好，價格較高;而發灰發黑、里面有黑色雜質的石膏粉質量較差。用手的拇指和食指搓捻石膏粉,手感發沙粗糙的石膏粉細度糙，質量較差、價格較低;而手感細膩的石音粉說明細度細，質量較好，價格也會較高。

　　(2) Apparently, gypsum powder with high whiteness has high fineness, good quality and high price, while gypsum powder with gray and black impurities is of poor quality. Twisting gypsum powder with the thumb and forefinger of the hand, the gypsum powder with rough feel of sofa is coarse in fineness, poor in quality and low in price; while the stone tone powder with fine feel is fine in fineness, good in quality and high in price.
