1. During the opening process, there will be many bubbles in the silica gel mold. What to do? This situation should be dealt with according to the situation. In case of vacuum extractor, mix silica gel and curing agent evenly, and then stop vacuum treatment. If there is no vacuum machine, the amount of curing agent can be increased properly and the disposal can be stopped. For example, the proportion of silica gel and curing agent is 4%, now it can be changed into 1% - 2%. In this way, the time for silica gel to be glued on the mold later will slow down, and the mold will gradually exhaust air and increase bubbles.

　　2. 硅膠模具固化后不均勻固化怎么辦?1. 硅膠與固化劑的比例不準確，沒有按要求稱重。2. 硅膠與固化劑的混合不夠仔細和均勻。出現這種情況會形成模具的失效，要盡量避免。

　　2. What about the uneven curing of silica gel mold after curing? 1. The proportion of silica gel and curing agent is not accurate, and it is not weighed as required. 2. The mixing of silica gel and curing agent is not careful and uniform. This situation will lead to die failure, which should be avoided as much as possible.

　　3.如何處理硅膠模具的外觀?這種情況是由于后期模具(產品型號)沒有合理的處理組成，所以在模具停止處理之前，模具的表面要比粗糙的模具干燥或做非常凌亂的模具，必須仔細打磨光滑清潔干凈。然后平均刷上釋放劑。常用的釋放劑有凡士林、清潔劑、液體石蠟等。可根據實際操作的原料不同，對模具刷不同的脫模劑。二是固化劑混合均勻后倒入模具中，去掉一塊干一塊。

　　3. How to deal with the appearance of silica gel mold? This situation is because the mold (product model) at the later stage does not have a reasonable treatment composition, so before the mold stops processing, the surface of the mold should be dry or very messy than the rough mold, and it must be carefully polished, smooth, clean and clean. Then brush the release agent evenly. The commonly used release agents are Vaseline, detergent, liquid paraffin, etc. According to the actual operation of different raw materials, the mold brush different release agent. The second is to mix the curing agent evenly and then pour it into the mold, remove one piece and dry one piece.

　　4. 如何處理硅膠模具產品的變形?這應該根據產品的大小來分開處理，尺度是產品的大小和硅膠的硬度的使用成反比。如果小產品或非常精細的產品可以用軟硅膠開模，硬度一般在10-20度，這樣解調效果會很好，但不會破壞精細產品的質感。如果大型產品如50cm以上的產品必須使用硬度為40-50的硅膠來開模。所以它不會變形。如果做的產品很大很細可以用硬度在30度左右的硅膠來開模(方法是先刷一層硅膠，上面覆蓋一層玻璃纖維布，然后刷一層硅膠……)。，內部可由石膏、玻璃纖維增強塑料(即不飽和樹脂+玻璃纖維布)制成外膜，從而保持產品的變形。

　　4. How to deal with the deformation of silica gel mold? It should be treated separately according to the size of the product. The scale is that the size of the product is inversely proportional to the hardness of silica gel. If small products or very fine products can be molded with soft silica gel, the hardness is generally 10-20 degrees, so the demodulation effect will be good, but the texture of fine products will not be damaged. If large-scale products such as products over 50cm must use silica gel with hardness of 40-50 to mold. So it doesn't deform. If the product is very large and thin, the mold can be opened with silica gel with hardness of about 30 degrees (the method is to brush a layer of silica gel first, cover it with a layer of glass fiber cloth, and then brush a layer of silica gel ) The inner part can be made of gypsum, glass fiber reinforced plastic (i.e. unsaturated resin + glass fiber cloth) to make the outer film, so as to maintain the deformation of the product.

　　5. 外模的制作方法和材料一般是用橡膠板或木板將模具圍起來，用石膏填充模具柜也可以。另一種選擇樹脂涂擦方法，涂擦一層樹脂粘一層玻璃纖維布，再涂擦粘，重復兩三層即可結束模具外模。

　　5. The production method and material of the external mold are generally rubber plate or wood plate to enclose the mold, and gypsum can also be used to fill the mold cabinet. Another way is to choose the resin coating method, wipe a layer of resin to stick a layer of glass fiber cloth, then rub and stick, repeat two or three layers to end the mold.

　　6. 真硅油和假硅油?

　　6. True and false silicone oil?

　　(1)用目測法:假硅油要比純硅油，比氣味大，有臭味;

　　(1) visual inspection: the false silicone oil is bigger than the pure silicone oil, and has a bad smell;

　　(2)火試:大部分硅油接觸玻璃棒或鐵棒后點燃，能點燃并發出黑煙的油為白化油，因為白化油是石化產品。純硅油不易燃，無呼吸，透明透明，。硅油的閃點是320度，白礦油的閃點是100度。

　　(2) fire test: most of the silicone oil is ignited after contacting the glass rod or iron rod, and the oil that can ignite and emit black smoke is albino oil, because albino oil is a petrochemical product. Pure silicone oil is non flammable, non breathing, transparent and non-toxic. The flash point of silicon oil is 320 degrees, and that of white mineral oil is 100 degrees.

　　(3)冰點試驗方法:取100克純硅油和100克白礦油，一起放入冰箱，調節-5-10度。經過兩個小時的實驗，假硅油會顯得純凈或凝固。真正的硅油是透明的，即使在零下50度它也不會凍結。

　　(3) freezing point test method: take 100g pure silicone oil and 100g white mineral oil, put them into refrigerator together, adjust them to - 5-10 ℃. After two hours of experiment, the pseudosilicone oil will appear pure or solidified. The real silicone oil is transparent and will not freeze even at minus 50 degrees.

　　7. 片模或片模操作方法:通過刷涂或灌注停止真空泵送硅膠的施工。假設你做的某件模具或部件有選擇涂覆方法，涂覆一般產品或你想做的模型在涂覆前要刷一層脫模劑或脫模劑，然后把硅膠涂覆在產品下面(注:一定要等30分鐘后，柱子表面將加一層薄紗或玻璃纖維緯紗布增強程度，然后涂刷第二遍硅膠和硅膠后單調，外面做模具，外面的模具可以用石膏或樹脂材料。

　　7. Operation method of sheet mold or sheet mold: stop the construction of vacuum pumping silica gel by brushing or pouring. Suppose that a mold or component you make has a selective coating method. Before coating the general product or the model you want to make, you need to brush a layer of release agent or release agent, and then apply silica gel under the product (Note: after 30 minutes, a layer of gauze or glass fiber weft gauze will be added to the column surface to enhance the degree, and then the second layer of silica gel and silica gel will be monotonous, and the mold will be made outside, The mold on the outside can be made of gypsum or resin.
