Problems solved by technology

[0003] The existing technology is the method of using deep freezing or applying a release agent: deep freezing needs to lower the temperature below -10°C to demould smoothly, which requires a lot of freezing equipment and energy consumption, resulting in investment, energy consumption and labor costs. Waste; smearing the release agent requires manual application of the release agent, and the second is that the release agent will have a certain impact on product performance and use, and there are also obvious deficiencies

Embodiment 1

[0012] The soft microcrystalline wax heated to 125°C (drop melting point 80°C) is put into a mold equipped with silicone resin coated film paper (the average molecular weight of silicone resin is 1500), and after the wax is completely solidified, it is taken out from the mold. When the coated paper was opened at a temperature of 20°C, neither the coated paper nor the wax changed.

Embodiment 2

[0014] The soft microcrystalline wax heated to 85°C is put into a polyethylene-coated paper bag (the average molecular weight of polyethylene is 25×10 4 ) in the mold, after the wax is completely solidified, take it out from the mold. When the coated paper was opened at a temperature of 20°C, neither the coated paper nor the wax changed.

Embodiment 3

[0016] The soft microcrystalline wax heated to 100°C is put into a mold equipped with a silicone resin-coated paper bag (the average molecular weight of the silicone resin is 3500), and cooled to 40°C at room temperature. At this time, the wax in the paper bag has completely solidified. Take out the paper bag containing the wax, peel off the coated paper, and find that there is no adhesion between the paper bag and the wax, and the paper and the coating film of the paper bag are not damaged. There is no difference between the properties of this wax and that before bagging.

[0017] After repeated use for 5 times in this way, the coated paper is still intact.

Abstract

The present invention discloses microcrystalline wax forming and packing process. Film coating paper is used as the packing material. Molten soft is injected into mold with film coating paper, and the cooled wax is packed in the once packing process. The packed microcrystalline wax is used after being unpacked and has no influence of isolating agent. Compared with available technology, the present invention has the advantages of simple operation, easy use, low packing cost, automatic packing process, no influence on the quality of the product, etc.

Description

technical field [0001] The invention relates to a molding and packaging method of microcrystalline wax, in particular to a molding and packaging method of soft microcrystalline wax. Background technique [0002] Soft microcrystalline wax is a special microcrystalline wax product, which is an important raw material for the production of pharmaceuticals, daily chemicals and other fine chemical products. However, due to its high penetration and adhesiveness, its molding and packaging have become difficult problems in production. [0003] The existing technology is the method of using deep freezing or applying a release agent: deep freezing needs to lower the temperature below -10°C to demould smoothly, which requires a lot of freezing equipment and energy consumption, resulting in investment, energy consumption and labor costs. Waste; smearing the release agent requires manual application of the release agent, and the second is that the release agent will have a certain impact...
