1、 Effect of removing pollution on stone

它是指清除石塑UV板上的污染的能力。石塑UV板清除实际上就是一种施工，不可能没有时间限制，因此，短时间观察清洗效果就显得不可少，可找与将要被清洗的石塑UV板污染一致的品种，或在将要清洗的面积的边角先作小样试验，使用与将要大面积应用的方法清洗小样，观察清洗结果。

It refers to the ability to remove the pollution on the stone plastic UV board. The removal of stone plastic UV board is actually a kind of construction, and there can be no time limit. Therefore, it is necessary to observe the cleaning effect in a short time. You can find a variety consistent with the pollution of the stone plastic UV board to be cleaned, or make a small sample test at the corner of the area to be cleaned, clean the small sample with the method to be applied in a large area, and observe the cleaning results.

二、稳定性

2、 Stability

作为一种可以在室内外使用的产品要适应一般常规的自然条件，稳定性是它使用的基本条件，适应范围应在-40～60℃之间，可用少量产品置于烧杯中，放置烘箱和冰箱中，然后，使之恢复至室温后观察，其外观与气味应与未测之前大致一样。

As a product that can be used indoors and outdoors, it should adapt to the general conventional natural conditions. Stability is the basic condition for its use. The adaptation range should be - 40 ~ 60 ℃. A small amount of products can be placed in a beaker, placed in an oven and refrigerator, and then observed after it is restored to room temperature. Its appearance and smell should be roughly the same as before.

三、可操作性

3、 Operability

它是施工的便利条件，部分清洗剂的使用条件过于苛刻，需要一定温度、干燥度、通风条件、时间等，都给施工人员带来不便。

It is a convenient condition for construction. The use conditions of some cleaning agents are too harsh, requiring certain temperature, dryness, ventilation conditions, time, etc., which bring inconvenience to the construction personnel.

四、可清除性

4、 Cleanability

石塑UV板清洗剂清洗完毕后，应能用水清除或其他材料清洗干净，且不留任何气味和残留物痕迹。

After the stone plastic UV board cleaning agent is cleaned, it shall be able to remove it with water or other materials without leaving any odor and residue traces.

五、安全性

5、 Security

清洗剂的国家标准目前尚没有制定出，但是可以参照国家十项《室内装饰材料有害物质限量》、《民用建筑工程室内环境污染控制规范》进行控制使用，或送检测，施放苯、二甲苯；甲醛、二甲醛等后刺激性气味，对人眼、鼻有灼热、灼疼感觉，对皮肤有刺痒、灼疼、热感，对黏膜、呼吸系统刺激的都应引起注意。有关行业部门应前瞻性地提前制定出清洗剂的安全性标准。

At present, the national standard of cleaning agent has not been formulated, but it can be controlled and used with reference to the national ten national limits of harmful substances in interior decoration materials and code for indoor environmental pollution control of civil construction engineering, or sent for testing and release of benzene and xylene; The post irritant smell of formaldehyde and formaldehyde has the feeling of burning and pain to human eyes and nose, itching, burning and heat to skin, and irritation to mucous membrane and respiratory system. Relevant industry departments should formulate the safety standards of cleaning agents in advance.

六、外观

6、 Appearance

清洗剂的液体产品不应分层、没有悬浮物或沉淀，同一种产品颜色应一致，在夏季或冬季应不变色；胶质、浆状产品颜色要一致，手感要软硬一致；喷撒型产品要有均匀的效果；粉状产品不能结块，形态细腻、均匀。

The liquid product of cleaning agent shall not be layered, free of suspended solids or precipitation. The color of the same product shall be consistent and shall not change color in summer or winter; The color of colloidal and paste products shall be consistent, and the hand feel shall be consistent with the soft and hard; Spraying products shall have uniform effect; Powdered products shall not agglomerate, and the shape shall be fine and uniform.

七、气味

7、 Smell

清洗剂(包括固体、气体、液体)有无类似苯、丙酮、煤油、鱼腥、辛辣、汽油、恶臭等刺激性气味、使人窒息的感觉，这类气味是否是国家明令禁止在人工操作时不允许使用的。当然，在石塑UV板清洗剂中完全没有一点气味也不现实，但在石塑UV板小样试验之后，这类气味应当可以在短时间消除，且不能传递到其他物体上。这是判断该产品本身是否有污染或形成新的污染源的关键。

Whether the cleaning agent (including solid, gas and liquid) has irritating smell and suffocating feeling like benzene, acetone, kerosene, fishy, spicy, gasoline and stench, and whether such smell is prohibited by the state in manual operation. Of course, it is unrealistic to have no smell at all in the stone plastic UV plate cleaning agent, but after the small sample test of stone plastic UV plate, this kind of smell should be eliminated in a short time and cannot be transmitted to other objects. This is the key to judge whether the product itself has pollution or forms a new pollution source.
