2021-10-29   Pageview:57

1, Anti-mildew agent for coatings with excellent antibacterial properties, broad spectrum sterilization, especially for Aspergillus, Penicillium and other special effects.

2, pure water-based formula, zero VOC, safe to use and transport.

3, coating anti-mildew agent product particle size is small, easy and stable uniform dispersion.

4, does not contain heavy metals, small irritation to human body, product safety and environmental protection.

5, paint anti-mildew agent good temperature resistance, and the applicable pH in 2-10 can be used.

6, paint anti-mildew agent strong resistance to water washing, not afraid of washing, durable and effective.

 

 

 

 

 

 

 

 

 

 

 

The complete flow curve and information about the flow characteristics of the liquid can only be measured by relatively expensive devices. At this time, only a small amount of liquid is required, placed on a flat plate, and the rotating cone is driven by a very sensitive air bearing and electronic device. To measure the required force [10]. It can not only control the speed and record the force applied, but also control the force and record the speed, such as an ICI viscometer.

Viscosity and coating performance
A complete rheological curve can give a lot of information about coating properties, see Figure 5-11. The pigment/filler precipitation in the coating occurs when the shear rate is lower than 1/s, and the sagging and leveling of the coating film on the vertical surface is generated when the shear rate is 1-10/s, stirring and The shear rate during dumping is from 10/s to several hundred/sec, and the shear rate for most constructions ranges from several hundred/sec to tens of thousands/sec.

The different stages of the rheology curve have their specific effects in the actual application of the coating. For the paint manufacturer, it is the most ideal if the entire range of the rheology curve can be controlled. The best sag resistance is at low shear. A higher value is required for the cutting rate, on the contrary, a lower value is required for the best leveling. The stress yield value makes leveling difficult, but it is beneficial to combat sag. In the brushing process, in order to resist splashing, a higher viscosity value is often required at a high shear rate. In the spraying process, in order to obtain a finer atomization point, a lower value is often required at a high shear rate. In some cases, balance must be required. How to achieve this balance will be described later.
