雙液澆注機(jī)如何防止膠水沉淀?
雙液點(diǎn)膠機(jī)使用的膠水主要是AB膠。AB膠通常有環(huán)氧樹(shù)脂、硅膠、聚氨酯。當(dāng)膠水是黑色或深灰色時(shí)，里面就會(huì)有填充物。和環(huán)氧樹(shù)脂一樣，聚氨酯膠通常是在A膠中填充。硅膠，如果是硅膠的比例，那么A膠和B膠有填充。
The glue used in the double liquid dispenser is mainly AB glue. AB gum usually has epoxy resin, silica gel, polyurethane. When the glue is black or dark grey, there is a filler in it. Like epoxy resins, polyurethane adhesives are usually filled in A adhesives. Silica gel, if the proportion of silica gel, then A gel and B gel are filled.
填料成分較多，有的硅粉、有的石英砂、有的石灰粉等填料起到導(dǎo)熱和散熱作用，增加硬度。但這些填料是硬的，會(huì)沉淀，這是層與膠水。如果涂上一層，膠水的特性就會(huì)發(fā)生變化，密度也會(huì)發(fā)生變化，導(dǎo)致配比發(fā)生變化，使膠水不做，膠水的背面固化部分的特性，沖洗出來(lái)的產(chǎn)品不合格。
There are many fillers, some silica powder, some quartz sand, some lime powder and other fillers play the role of heat conduction and heat dissipation, increasing hardness. But these fillers are hard and will precipitate, which is the layer and glue. If coated with a layer, the characteristics of glue will change, and the density will also change, resulting in changes in the proportion, so that the glue does not do, the characteristics of the back solidification part of glue, flushed products are not qualified.
雙液澆注機(jī)如何防止膠水沉淀?
How to prevent glue precipitation in double-liquid pouring machine?
1. 添加攪拌功能到物料桶中。開(kāi)機(jī)后，攪拌器不斷旋轉(zhuǎn)攪拌膠水，防止膠水沉淀。另外，攪拌棒的作用要長(zhǎng)一些。如果棒子太短，夠不到底部，膠水就會(huì)沉淀。
1. Add stirring function to material barrel. After startup, the agitator continuously rotates to mix glue to prevent glue precipitation. In addition, the stirring rod has a longer effect. If the stick is too short to reach the bottom, the glue will settle.
2. 倒膠前，打開(kāi)膠包桶，用攪拌棒或攪拌鉆攪拌，然后倒入料桶中。如下圖所示:
2. Before pouring, open the plastic bag bucket, stir it with a stirring rod or a stirring drill, and then pour it into the barrel. As shown in the following figure:
3、可以買(mǎi)一些質(zhì)量好的膠水，質(zhì)量好的膠水，填料比較小，顆粒比較細(xì)，沉淀不那么嚴(yán)重。
3. You can buy some good quality glue, good quality glue, filler is small, particle is fine, precipitation is not so serious.
4. 購(gòu)買(mǎi)生產(chǎn)日期較近的膠水。膠水放的時(shí)間越長(zhǎng)，沉淀就越嚴(yán)重。
4. Purchase glue with nearer production date. The longer the glue is released, the more serious the precipitation will be.
5、倒膠機(jī)好每天保持運(yùn)轉(zhuǎn)，不要長(zhǎng)時(shí)間使用。如果你長(zhǎng)時(shí)間不使用，比如一個(gè)星期或半個(gè)月，把膠水從桶里拿出來(lái)，用酒精清洗。否則膠水會(huì)沉淀在桶和管道里。
5. It's better to keep the pouring machine running every day instead of using it for a long time. If you don't use it for a long time, such as a week or half a month, take the glue out of the bucket and wash it with alcohol. Otherwise the glue will settle in barrels and pipes.
6. 為了防止沉淀，管道越短越好。管子太長(zhǎng)，膠水容易在里面沉淀。
6. In order to prevent sedimentation, the shorter the pipe is, the better. The pipe is too long and the glue deposits easily in it.
