Summary of key points for exporting pigment inks: Polyether characterizes water-based polyurethane, which is almost always composed of acrylic acid and acrylic acid. Polyether characterizes water-based polyurethane, and its viscosity is generally higher than 001 ° C.
To ensure the relative viscosity of waterborne polyurethane, it has the function of a filter. If acrylic polyurethane is lower, the effect will also be better. In order to complete this task, it is necessary to add a certain amount of cross-linking material, which causes the ink to solidify incompletely and become thicker, and the viscosity of the ink will also be slightly higher. This is due to the poor thermal stability of polyurethane.
When choosing water-based polyurethane ink, it is necessary to consider various factors, such as the composition and manufacturer of iron pigments, which are generally 4-8%. However, polyurethane also has some epoxy ethane generated by reaction with EP, and there may even be a trend of accelerating curing. So how to quickly cure? At present, there are mainly the following systems: hydroxyacetic acid, etc. The viscosity of silicone oil evaluated by the former is quite high, and the viscosity and pH value of acetone are better.
High molecular weight hydroxysilicone oil emulsifier with very fine molecular weight characteristics. Its molecular weight is smaller, its volatility is better, its temperature resistance is better, and its freezing point and viscosity are extremely low.
Improve the performance of certain synthetic adhesives, such as improving whiteness at room temperature by ≥ 02%; 900~107, 94%; Medicinal materials and products made from silicone oil have no adverse effects on pharmaceutical equipment, and have excellent therapeutic effects on heat conduction, gilding paper, light conduction, heat pressure, weak immunity, and other aspects.
This is a unique performance created by high molecular weight hydroxyl silicone oil, which can be made into various viscosities through emulsification, resulting in a better elastic feel.
It is a new type of modified silicone elastomer polymer unique to high molecular weight hydroxy silicone oil, and its molecular main chain is easy to spread, thus possessing excellent anchoring ability and slip resistance. Compared with traditional amino polymer modified silicone oil, it can give the fabric a more excellent smooth and soft feel. However, due to the immense weakness of its molecular chain, it cannot be cycled.
By using small molecule hydroxyl silicone oil molecules as a special functional additive for interfacial active agents, the fabric is endowed with a fluffy, soft, and smooth feel.

Put the emulsified oil into the reactor stirring kettle, designed to obtain the oil for endothermic reaction. The requirement for reaction temperature is relatively high, and it is recommended to have a reaction temperature of 10-20 ° C to achieve a higher reaction effect.
