Because the required items are all available, it was only a short period of time, and Yan Xihuan guided Hao Jun to officially operate. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

In front of Hao Jun is a silicone mold of the zodiac, which is relatively simple, and he mainly wants to experience the delicate operation that is different from the large pieces.

The 12 zodiac silicone molds are half a book-sized cuboid, with two rows of twelve model cavities on it, one for each of the 12 zodiac signs, and it is a set to make it. Hao Jun had often seen similar products in night markets and tourist areas before, and at first glance they looked like jade.

Hao Jun first adjusted the unsaturated resin, then added a little grass green, stirred well, and poured it into the model cavity in turn.

When mass production, everyone has to face dozens of sets of molds and a lot of materials, but Hao Jun is now experimenting with one set of experiments, so he has to calculate the materials and try to avoid waste.

Although the specific shape of each pendant is different, the basic materials are not much different, and a total of 45 grams of resin need to be injected into the twelve model cavities, plus the loss of hanging walls when the seasoning, etc., in fact, 467 grams of seasoning are needed.

Because the room temperature is now low, in order to ensure that it cures in a certain period of time, the resin of component A is a little more, and it is about 1.3 to 1 of component B.

When Hao Jun injected the seasoned material into the model cavity, he found that the wall could still be scraped a little, so he scraped it with a small bamboo board of the seasoning, and injected the slightly lacking model cavity in turn, basically keeping the thickness of this set of zodiac signs consistent.

It doesn't matter if the current material is a little higher, the resin will shrink a little when it cures.

Hao Jun shifted the injected molds to the side and began to operate the other set.

The first set was mixed with a bit of grass green to mimic the uniform color of Xiuyu, and this set was a little more complicated to reflect the feeling of jadeite.

Hao Jun first adjusted the unsaturated resin as usual, and then added some aluminum oxide, and the crystal clear resin immediately had the feeling of waxy jadeite.

After stirring well, they are slightly placed, and when they are slightly viscous, Hao Jun quickly pours them into the model cavity.

If it is poured early, the slightly heavier aluminum oxide will be deposited at the bottom, and after demolding, it will be deposited on the front, and the feeling of looking like jadeite will be greatly reduced, and it is more appropriate to say that it is plastic.

If it is late, the leveling of the resin is reduced, and some details of the model cavity may have problems such as lack of materials and bubbles.

Hao Jun left some extra ingredients in the mixing cup, immediately transferred the emerald green, poured it into the twelve model cavities in turn, and then outlined it with a toothpick, so that the emerald green produced the feeling of emerald roots spreading, which looked more realistic......

In two hours, under the guidance of Yan Xihuan, Hao Jun experimented with nine methods in different ways, and the 12 zodiac signs after demolding will present nine different feelings.

Some are like Xiuyu, some are like jade, some are like agate, some are like turquoise, and some are like Hetian jade, as long as they don't look like plastic at a glance, they are successful.

It will take until the afternoon for the resin to fully cure, and the smell and the smell of the exothermic reaction during the curing process are not very good, even if the ventilation device is turned on on the workbench, Hao Jun, who has never liked the smell, still has the feeling of wanting to snort a few times.

So, they switched to another workbench.

Next, Yan Xihuan wants to guide Hao Jun to make the night pearl, and the main raw material is still unsaturated resin.

If vacuum deaeration is used after injection, the process is much simpler, but what Yan Xihuan wants to teach Hao Jun is handmade.

Instead of using a conventional mold, they split a ping-pong ball in half as two model cavities.

Yan Xihuan reminded Hao Jun that not every table tennis ball can be used to make molds, because the unsaturated resin will release heat during the curing process, and some table tennis balls will be roasted and deformed, and the resin that has not yet been fully cured will of course be deformed, and the appearance of the finished product will be miserable.

If you need to use other items to make molds, you should also pay attention to this, and also consider the problem of discoloration of some mold substitutes after heating.

Under the guidance of Yan Xihuan, Hao Jun first adjusted the unsaturated resin as usual, then mixed in luminous powder and refractory soil according to a certain proportion, stirred evenly, placed slightly, and then slowly poured into the two model cavities.

When both sides began to cure, Hao Jun adjusted a little resin and poured it on the surface of one of the sides, because there were not many of them, the leveling was slow, and he needed to use a toothpick to help.

Then, he fastened the other half upside down and fixed it slightly, and as the resin cured, the two hemispheres were seamlessly glued together.

Hao Jun then experimented with different proportions of luminous powder and refractory clay, and made markings.

In the afternoon, it is much more comfortable to make a color-changing bracelet, because the main raw material is silicone rubber, and compared with resin when curing, the taste is negligible.

In silicone rubber, different light-sensitive color-changing and temperature-sensitive color-changing materials are mixed into a certain proportion, and the bracelet made has different color-changing effects.

For example, when the ultraviolet rays in the sunlight are strong, the entire bracelet is the color of eggplant purple. When the ultraviolet rays are a little stronger, the whole bracelet is a decent purple. When ultraviolet rays are average, the whole bracelet is pink-purple......

For example, when the body temperature is 37 degrees, the bracelet is pale pink, 38 degrees is pink, 39 degrees is magenta, and 40 degrees is jujube red......

Hao Jun made ten color-changing bracelets that gave them different functions.

It is also more interesting to make a treasure tree out of epoxy resin, a bit like a child playing with plasticine, when the epoxy resin is half-solidified, Hao Jun plucks out a big tree at will, and then hangs glow-in-the-dark, color-changing, and sparkling small things on it as if it were a Christmas tree.

Just as Hao Jun was holding a brush to paint the colors of the tree, Fan Ping called.

Hao Jun guessed that she must be in a hurry to find herself now, so he quickly wiped his hands and picked it up.

Fan Ping knew that he was in the workshop, and it was not easy to say too much, so he only said seven words: "That feeling is coming again!"

Hao Jun immediately understood.

The so-called feeling must refer to the feeling I told him before, and I always felt that the factory was being watched in the past month. Fan Ping has always vaguely felt that she has something to do with Fan Tai, because every time her feeling of being watched is strong, Fan Tai will be very calm.

But at this moment, Fan Tai has been replaced by Hao Jun, but Fan Ping still has that feeling, is it the wrong direction that Fan Ping suspected before? Or is it because Fan Tai has not been in touch for the past few days, so he can't hold his breath?
