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板清除實際上就是一種施工，不可能沒有時間限制，因此，短時間觀察清洗效果就顯得不可少，可找與將要被清洗的石塑UV板污染一致的品種，或在將要清洗的面積的邊角先作小樣試驗，使用與將要大面積應用的方法清洗小樣，觀察清洗結果。

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、穩定性

2、 Stability

作為一種可以在室內外使用的產品要適應一般常規的自然條件，穩定性是它使用的基本條件，適應范圍應在-40～60℃之間，可用少量產品置于燒杯中，放置烘箱和冰箱中，然后，使之恢復至室溫后觀察，其外觀與氣味應與未測之前大致一樣。

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

它是施工的便利條件，部分清洗劑的使用條件過于苛刻，需要一定溫度、干燥度、通風條件、時間等，都給施工人員帶來不便。

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板清洗劑清洗完畢后，應能用水清除或其他材料清洗干凈，且不留任何氣味和殘留物痕跡。

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

清洗劑的國家標準目前尚沒有制定出，但是可以參照國家十項《室內裝飾材料有害物質限量》、《民用建筑工程室內環境污染控制規范》進行控制使用，或送檢測，施放苯、二甲苯；甲醛、二甲醛等后刺激性氣味，對人眼、鼻有灼熱、灼疼感覺，對皮膚有刺癢、灼疼、熱感，對黏膜、呼吸系統刺激的都應引起注意。有關行業部門應前瞻性地提前制定出清洗劑的安全性標準。

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、外觀

6、 Appearance

清洗劑的液體產品不應分層、沒有懸浮物或沉淀，同一種產品顏色應一致，在夏季或冬季應不變色；膠質、漿狀產品顏色要一致，手感要軟硬一致；噴撒型產品要有均勻的效果；粉狀產品不能結塊，形態細膩、均勻。

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、氣味

7、 Smell

清洗劑(包括固體、氣體、液體)有無類似苯、丙酮、煤油、魚腥、辛辣、汽油、惡臭等刺激性氣味、使人窒息的感覺，這類氣味是否是國家明令禁止在人工操作時不允許使用的。當然，在石塑UV板清洗劑中完全沒有一點氣味也不現實，但在石塑UV板小樣試驗之后，這類氣味應當可以在短時間消除，且不能傳遞到其他物體上。這是判斷該產品本身是否有污染或形成新的污染源的關鍵。

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.
