Plastic steel door titanium door which is good
It depends on your request. Plastic doors Features: good insulation, sound insulation is good, the disadvantage is only one-way open, the switch is not very convenient, easy to deformation fall, the door hinge will adjust. Titan door features beautiful and bright, modern atmosphere, open the direction of freedom, easy maintenance and practical, the shortcomings of the closed is not good noise is not good. The vast majority of shops are selected titanium door, showing its better than steel doors.
1, steel doors Advantages:
(1) plastic steel door material with fire, no spontaneous combustion, no combustion, self-extinguishing.
(2) thermal conductivity than wood, metal is much lower; insulation effect is much better than aluminum.
(3) between -30 ℃ to -70 ℃, the sun, rain, dry, humid environment, no deformation, no discoloration, not brittle, but also acid and alkali drugs and waste salt erosion, , Cement, glue effect.
(4) well-designed door structure with drainage, seams tight, can completely separate the rain, the sound is less than 20 UP.
(5) the use of cleaning agents after cleaning as bright, the service life of up to 30 years or more.
2, plastic steel door Disadvantages:
Plastic doors can only open one-way, the switch is not convenient, easy to deformation.
3, titanium door advantages:
(1) high strength, good rigidity, light weight.
(2) the use of temperature than aluminum alloy several hundred degrees, at moderate temperatures can still maintain the required strength.
(3) titanium alloy in the humid atmosphere and sea water medium work, its corrosion resistance is much better than stainless steel; pitting, acid corrosion, stress corrosion resistance is particularly strong; alkali, chloride, chlorine organic products, Nitric acid, sulfuric acid, etc. have excellent corrosion resistance. But the titanium has a reducing oxygen and chromium salt medium corrosion resistance is poor.
(4) titanium alloy at low temperature and ultra-low temperature, can still maintain its mechanical properties.
4, titanium door defects:
The main limitation of titanium and titanium alloys is poor chemical reactivity at high temperatures with other materials. This property forces the titanium alloy to be different from the conventional refining, melting and casting techniques, and even often causes damage to the mold; as a result, the price of the titanium alloy becomes very expensive
