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.
