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. 硅胶模具固化后不均匀固化怎么办?1. 硅胶与固化剂的比例不准确，没有按要求称重。2. 硅胶与固化剂的混合不够仔细和均匀。出现这种情况会形成模具的失效，要尽量避免。

　　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.如何处理硅胶模具的外观?这种情况是由于后期模具(产品型号)没有合理的处理组成，所以在模具停止处理之前，模具的表面要比粗糙的模具干燥或做非常凌乱的模具，必须仔细打磨光滑清洁干净。然后平均刷上释放剂。常用的释放剂有凡士林、清洁剂、液体石蜡等。可根据实际操作的原料不同，对模具刷不同的脱模剂。二是固化剂混合均匀后倒入模具中，去掉一块干一块。

　　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. 如何处理硅胶模具产品的变形?这应该根据产品的大小来分开处理，尺度是产品的大小和硅胶的硬度的使用成反比。如果小产品或非常精细的产品可以用软硅胶开模，硬度一般在10-20度，这样解调效果会很好，但不会破坏精细产品的质感。如果大型产品如50cm以上的产品必须使用硬度为40-50的硅胶来开模。所以它不会变形。如果做的产品很大很细可以用硬度在30度左右的硅胶来开模(方法是先刷一层硅胶，上面覆盖一层玻璃纤维布，然后刷一层硅胶……)。，内部可由石膏、玻璃纤维增强塑料(即不饱和树脂+玻璃纤维布)制成外膜，从而保持产品的变形。

　　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胶板或木板将模具围起来，用石膏填充模具柜也可以。另一种选择树脂涂擦方法，涂擦一层树脂粘一层玻璃纤维布，再涂擦粘，重复两三层即可结束模具外模。

　　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)用目测法:假硅油要比纯硅油，比气味大，有臭味;

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

　　(2)火试:大部分硅油接触玻璃棒或铁棒后点燃，能点燃并发出黑烟的油为白化油，因为白化油是石化产品。纯硅油不易燃，无呼吸，透明透明，。硅油的闪点是320度，白矿油的闪点是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)冰点试验方法:取100克纯硅油和100克白矿油，一起放入冰箱，调节-5-10度。经过两个小时的实验，假硅油会显得纯净或凝固。真正的硅油是透明的，即使在零下50度它也不会冻结。

　　(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:通过刷涂或灌注停止真空泵送硅胶的施工。假设你做的某件模具或部件有选择涂覆方法，涂覆一般产品或你想做的模型在涂覆前要刷一层脱模剂或脱模剂，然后把硅胶涂覆在产品下面(注:一定要等30分钟后，柱子表面将加一层薄纱或玻璃纤维纬纱布增强程度，然后涂刷第二遍硅胶和硅胶后单调，外面做模具，外面的模具可以用石膏或树脂材料。

　　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.
