निकृष्ट अॅल्युमिनियम कॉइल्स त्वरीत कसे ओळखायचे?

निकृष्ट अॅल्युमिनियम प्रोफाइलची वैशिष्ट्ये:

1. रासायनिक रचना अयोग्य आहे. उत्पादनातील विविध अॅल्युमिनियम आणि स्क्रॅप अॅल्युमिनियमच्या मोठ्या प्रमाणासह डोप केलेल्या अॅल्युमिनियम प्रोफाइलची किंमत मोठ्या प्रमाणात कमी झाली आहे, परंतु यामुळे अयोग्य इमारत अॅल्युमिनियम प्रोफाइल निर्माण होईल आणि बांधकाम प्रकल्पांची स्थिरता गंभीरपणे धोक्यात येईल.

2. निकृष्ट अॅल्युमिनियम प्रोफाइल सीलिंग वेळ मोठ्या प्रमाणात कमी करतात, reduce the loss of chemical reagents, and reduce the cost, but the corrosion resistance of the profiles is also greatly reduced.

3. Thin oxide film thickness. The standard stipulates that the oxide film thickness of architectural aluminum profiles should not be less than 10um (micrometers). If the thickness is not enough, the surface of the aluminum profile is easy to rust and corrode. In the random inspection, some aluminum profiles without production name, factory location, production license, and qualification certificate have an oxide film thickness of only 2 to 4um, and some do not even have an oxide film. According to expert estimates, every 1um reduction in oxide film thickness can reduce power consumption costs by more than 150 yuan per T profile.

4. रासायनिक रचना अयोग्य आहे. The aluminum profile mixed with a large amount of miscellaneous aluminum and scrap aluminum can greatly reduce the cost, but it will cause the chemical composition of the building aluminum profile to be unqualified, and seriously endanger the stability of the construction project.

Unqualified aluminum profiles may be deformed due to the influence of air, rain, sunlight, इ., and even cause glass breakage and fall off.
