In the afternoon of the fumigation of the summer heat, the drink is always too fast to retreat ice, and the time to eat cold noodles is too short.There is no ice, not enough, then we need ice to help, the traditional ice mold rebound is not good, easy to become brittle and aging, silica gel ice lattice can solve this problem.At present, there are all kinds of silica gel ice lattice on the market, so how to choose high quality silica gel ice lattice?
From the perspective of materials:
The silica gel raw material of the silica gel ice lattice must be food-grade silica gel, which is not harmful to human body. So we should first confirm whether the silica gel ice lattice has been certified as safe, has no tangy odor, is safe and not easy to age, and can directly contact food, so as to use it at ease and eat at ease.
From the perspective of production technology:
The normal vulcanized silica gel cake mold of raw materials needs to be divided into several process parts. The determination of materials, such as (hardness, standard materials, material rebound and tensile, high and low temperature resistance, etc.) vulcanizing agent (length of curing time, anti-yellow composition of the product,And deformation components, etc.) the standard of normal mixing of raw materials and vulcanizing agent (mixing time depends on the dispersion degree of color glue and sulfur), in high temperature molding
For silicone ice, commonly used materials for food grade silica gel production and processing, contact with the human body more at ease, in terms of performance is more comprehensive, and ordinary silicon rubber are also able to produce, only on the material properties and various aspects on the performance and service life can not get the guarantee of long-term, such as the back stretch, long-term to appear in yellow, did not rebound phenomenon and so on,
