What are the characteristics of high quality UVC profile?

The UPVC profile is of high quality and a number of quality indicators, which we will continue to compare.


Number

Characteristic

Acceptable range

Control method

1

Appearance of profiles

White, clear and smooth

Ocular control

2

Exterior walls

The exterior wall thickness in Class A is about 3 mm

Controlled by an outer wall thickness caliper

3

Additives

All additives needed to produce profiles and especially titanium oxide from high quality materials and brands

UV test certification by accredited laboratory authorities

Additive Test Impact Verification Confirmation of the Additive Manufacturing Company

4

Unit length mass

The mass of the window frame length would be at least 1200 g / m

Length and weight control by meters and scales

5

Raw materials consumed

Use new Raw materials in the production of profiles and not recyclables

Impact Testing by Accredited Laboratory Authorities Impact Testing Approval

6

Channel

The number of channels in the profile improves the mechanical and physical properties of the profiles so that the more channels, the less heat and sound energy transfer.

In Iran, 3 and 4 channel profiles are common

The number of channels is counted among the main profiles

7

Fragile

Resistant to impact at low temperatures and environments

Confirmation of testing by accredited laboratory authorities

8

Color stability

No change of color profile

Confirmation of testing by accredited laboratory authorities (Grade A of the Center for Housing Research)

Have the approval of a reputable manufacturer of titanium oxide

9

Good weldability

Profiles can be welded properly

First, according to the profile specifications table in Chapter 5, samples are prepared and the force specified in the table is applied to the sample and must be greater than the stated values.
