When we decorate the house, the doors and windows are an indispensable decoration material. The quality of the purchase directly affects our life today. So when you buy, you need to know more and then buy. Heat-dissipating aluminum alloy doors and windows is a new decoration material, many people do not know how to buy when they buy. Today, Xiaobian will take a look at the hot-selling aluminum alloy doors and windows purchase tips and installation precautions!
Heat-dissipating aluminum alloy doors and windows purchase tips
1 look at the materials:
The aluminum profiles used for high-quality aluminum alloy doors and windows, thickness, strength and oxide film shall comply with the relevant national standards. The wall thickness of the inelastic assembly structure shall be 1.4 mm or more.
2 look at processing:
High-quality aluminum alloy doors and windows, fine processing, exquisite installation, good sealing performance, and easy to switch. Inferior aluminum alloy doors and windows, blindly selected aluminum profiles and specifications, processing rough and shoddy, sawing instead of milling, not installed according to requirements, poor sealing performance, switch is not free, not only leaking wind and rain and glass burst phenomenon, but also encountered When it comes to strong winds and external forces, it is easy to scrape or knock down the push-pull parts or the glass, causing damage to people.
3 look at the price:
Under normal circumstances, high-quality aluminum alloy doors and windows due to high production costs, the price is about 30% higher than inferior aluminum alloy doors and windows. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm have a tensile strength and yield strength that are much lower than the national standards and are not safe to use. 22 look at processing:

Heat insulation aluminum alloy door and window installation precautions
First, airtightness
1. Corner seal (adhesive angle):
The sealing strip should avoid corner stitching. The sealing strip at the corner should be designed as a 90 degree integral rubber angle.
2, frame fan seal:
It is advisable to design three sealing strips for the opening of the fan parts, namely the main sealing strip, the fan pressing strip and the frame pressing strip.
Second, anti-leakage
1. The outer window must be provided with drainage channel, drain port and exhaust hole (pressure balance hole) to discharge water in the window frame fan. A buckle cover shall be provided on the outside of the drain to prevent strong wind from blowing rain and dust into the window sash.
2. The heat insulation strip should adopt C-type structure, which is combined with the inner and outer aluminum profiles on the same horizontal surface to avoid leakage and corrosion hazard caused by water accumulation at the heat insulation strip. At the same time, the length of the insulation strip can be increased to improve the thermal performance.
3, door and window opening size: the structure of the hole should not be too large to avoid leakage difficulties caused by leakage.
4, the mouth: window for special reasons, such as the outer wall of the stone curtain wall, the hole is reserved for large size, the structure of the hole is recommended to do the mouth, the mouth should be poured with the concrete wall at the same time.
5, the outer window slab: the exterior wall material is the paint construction, it is recommended to use metal window sill. The inside of the metal window sill should be pressed into the window frame, and the outer side of the wall should be dripped.
6. Window frame and structure hole: The window frame should be installed in the vertical. If it is installed on the outside, it should be retracted 20mm inward to prevent the structural construction error from causing the window frame to be installed outside the structure skin, causing rainwater leakage.
Third, the frame fan structure
1. Group angle: Group angle is an important process related to the integrity of doors and windows.
Gluing process: Under normal circumstances, the corner code + smear angle glue process should be adopted, and the window corner is prohibited from being unsmeared or extruded.
Injection molding process: the corners can also be angle code + guide groove + injection hole + two-component injection + angle piece process to ensure the corner strength requirements, to ensure that the door and window products are not deformed after transport and installation. appear.

Nurses use the medical trolleys to transfer the pills and liquid medicine to patients, medical trolley caster wheels make the medical trolley moving. The medical caster wheels are widely used in many medical trolleys and other medical equipment. MYWIN could provide the plate & threaded mounting type for your choice. Including plate swivel, plate swivel with brake, threaded swivel, threaded swivel with brake.
The material of medical trolley caster we normally use is PU, transparent PU and so on. PU material has the characters like rotary quietness, anti-abrasion, corrosion resistance, which are very suitable for hospital environmental. One important thing need to remind you is that, please do not use the casters while exceed their maximum load capacity, accident is always caused by overload.
As the quality, our casters have the certification proof and have received testing after production. The regular salt and spray test and load capacity test are taken in our every caster. We also have the SGS, IAF, TUV and CNAS certification to make our customers more confident about our products.
