How to distinguish the silicone product
s quality is good or bad?
Silicone products manufacturer technical support does know how to distinguish the silicone products quality can make you forget a lot of trouble, bad quality of silica gel products not only let you spend the money, may also affect the user's health.
Silica gel products are many, the kinds of different silicone products to identify quality also is distinguishing, in short, we in the face of the silica gel products inspection on this issue need to master two main methods to identify the quality of the silica gel products.
First how to distinguish the silicone material is authentic and part of the factory in order to save the cost of using other similar silicone materials as silica gel materials, they have similar to silicone material hardness, handle, elasticity.
It is difficult to use intuitive judgment of true and false, and these materials relative to the silicone material cost is low, service life is shorter, aging resistance and other relevant properties has a great gap with silicone material.
For this kind of product, we can take the flame burning method to identify, authentic silicone products after flame burn does not produce a lot of smoke, will only produce a small amount of white smoke, and combustion is completed, will only leave a few white powder, the white powder is silicon dioxide.
If it is other than the environmental protection material can produce a large number of black smoke and second how to distinguish the silicone glue paste material products is unqualified, the silica gel products are using molding, and product quality was in large part by the mold design is reasonable at this time I will need to check whether the product winger is a craze, silica gel products once appear, craze, the product was not work, and this phenomenon is caused by hem the mould design is reasonable, so we looked in the silicone products, it must not pass product screening of fatal flaw here are several ways of silicone products to distinguish good or bad: silicone bracelet how to discern the stand or fall of silicone bracelet 1, false silica gel hand ring is easy to deformation, and silica gel will feel the springback is really good, pull permanent deformation is small.
2, if really the silicone surface without special handling hand feels feel more smooth, because there is a layer of surface layer is milky substance.
3, the silicone surface easy to stick dust and impurities such as hair.
Silicone bracelet look bad is primarily silica gel ink, the tensile strength is not enough to see how much you want to use prescription made of mixing rubber.
After these things forming light appearance and tension or bad sign.
The silicone bottle how to distinguish the quality of the silica gel bottles?
Silica gel bottles to identify quality can be done by the several aspects: 1, the silica gel is a kind of human body skin feel like the feeling of the material, a good silicone bottle is feel better in the first place.
When fed the baby, the baby often take hand holding a bottle and milk;
Good tactility is both good for baby's emotional stability, baby has help to the development of emotional intelligence, this also can't compare to the other material bottles.
A good silicone bottle will have good elasticity, silica gel elasticity is different from rubber: is not the sort of hard elastic, the flexibility of silicone is soft, delicate.
At the same time, you can try it in the bottle filled them with hot water, with water after the feeling will be more like human body skin.
2, convenience, silicone baby bottles and other bottles, in addition to performance better;
With a convenient and practical.
Namely: tear open outfit, more convenient to have universality, can and other pacifier, bottle used interchangeably (
Because most of the mother now use of glass or plastic bottles)
Now some silica gel bottles will tear open outfit, break up is not very practical: in the middle of the silica gel and plastic lid between installation card slot, set the card lines and so on.
Bottle is a daily use products, so the most important point to practical and convenient.
3, details on everyone know, silica gel because of material itself, are more likely to stick to dust.
So in the design, in addition to beautiful, even considering his dust.
For example: the silica gel bottle treasure is considered the dust on the bottle, the bottle made as part of the frosted;
Ensure the product already so beautiful, and to take care of the dust of the product;
Kill two birds with one stone of it.
Conclusion: how to identify the silicone products 1, if really silicone surface without special handling hand feels feel more smooth, because there is a layer of surface layer is grease material 2, false silica gel belt is easy to deformation, and silica gel will feel the springback is really good, pull permanent deformation is small.
You put the silicone cut off a little bit of burn, if not the flame only white smoke and Mars and burn down the white powder is silica gel.
Smell can also be silicone, but they have issues with sulfide agent.
3, silicone rubber surface easy to stick dust, hair lighter impurities.
4, good silicone without peculiar smell, encounter heat to soften not change color.
5, you put the silicone cut off a little bit of burn, the false edge of silicone wristbands after fire was black, fake silicone flame burning, smoke, black and stink.
But really the silicone, no matter what color of the silicone burning edge is white and burning residue as powder.
And silicone wristbands are really carbon combustion, the flame.
White smoke, tasteless.
If contact with petri dishes smoke, collection of white powder, the powder soluble in 40% naoh thermal solution (
Take a drop of the solution in a test tube, add two drops of ammonia molybdate, a little heat, add a drop of aniline solution and 3 - after cooling
8 the saturated sodium acetate solution, the color of solution reaction, if appear blue silicon, prove for silica gel.
