外观上辨别石膏粉质量的方法!

来源:https://www.jnfhjc.com 日期:2019-01-16 发布人:admin

对于从外观上辨别石膏粉质量的方法有哪些?下面由济南石膏粉的人员介绍一下:

  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:
  通过外观上观察和手感可初步判断石膏粉质量的优劣。观察就是看外观包装袋质量情况和石膏粉的外观颜 色,手感就是用手搓一搓石膏粉的糙细程度(细度)。
  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)若包装塑料编织袋的材质质量差、松软强度低、 做工粗糙、编织稀疏(单位面积内的经纬数目不达标)、颜 色发灰绿黑色、内部没有防潮塑料袋、出现撒料现象、三 无产品或外观标识(种类名称、生产厂家、商标、重量、联 系方式等)不齐全的石膏粉则很大可能不符合质量标准、 档次质量差,质量稳定性也不能保证。反之,那些包装塑 料编织袋用材好、做工精致、颜色发白、强度高、编织经纬 密集、内部有防潮塑料袋、封口严密、外观印刷清晰、标识 齐全、不撒料的石膏粉一般质量较好、档次高,质量有保证。一般使用这种包装袋的石裔粉白度高、细度细。若石 膏粉是质量上乘的、高附加值的高强度石膏粉、特种 石膏粉(如母模石裔粉、原模石膏粉或树脂石膏粉),其价 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)外观上看,白度高的石膏粉细度目数高,质量 好,价格较高;而发灰发黑、里面有黑色杂质的石膏粉质 量较差。用手的拇指和食指搓捻石膏粉,手感发沙粗糙的 石膏粉细度糙,质量较差、价格较低;而手感细腻的石音 粉说明细度细,质量较好,价格也会较高。
  (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.
