Scientific maintenance can prolong the service life of the steel

All materials have their own life, including our recognized the strength of the best building materials - steel. During the life of the steel if do not pay attention to maintenance and maintenance, its service life will be greatly reduced, especially with the development of science and technology and society, more and more strict to the service life of steel products. Shaanxi inovance steel pipe co., LTD. Is a large steel sales enterprise in northwest China, they not only have great prestige in the steel industry, is much better at identifying all kinds of high and low medium grade of steel, of steel has its own unique views on operation and maintenance. Shaanxi inovance steel pipe that, along with the modern living environment of the climatic conditions of great change and further complicated, steel pipe after installation requires corrosion protection and fire prevention. embalmed In the previous construction, for the leakage of steel is only two antirust paint, no regular maintenance measures, so this kind of anticorrosive practice effect is not significant. Use galvanized LouCheng plate, its effect also not too ideal. Column and steel beam steel purlin and other steel structure: the sand combination electric steel brush cleaning technology, thoroughly remove previous scale and rust; Use twice epoxy zinc-rich anti-corrosive primer, dry film thickness is 70 um, practical quantity is 0.25 ~ 0.3 kg / ¡; Twice thick epoxy micaceous iron ash slurry primer, wet film thickness is 190 um, dry film thickness is 100 um, paint pulp: curing agent by weight: 100:15. Galvanized LouCheng board: derusting mainly adopts electric steel brush manual derusting, ensure cleaning thoroughly. LouCheng board of corrosion is serious, the use of atomic ash reinforcement, smooth, after being dry twice epoxy zinc-rich anti-corrosive primer, dry film thickness is 70 um, practical quantity is 0.25 ~ 0.3 kg / ¡; Twice thick epoxy micaceous iron ash slurry primer, wet film thickness is 190 um, dry film thickness is 100 um, paint pulp: curing agent by weight is: 100-15, anticorrosive processing. Fire prevention Fire prevention is an important feature of modern architecture, for steel, its low temperature resistance, many performance will change with temperature rise and fall, when the temperature reaches 430-540 , the steel yield point, tensile strength and elastic modulus will fell sharply, lose bearing capacity. Must be used for refractory steel structure for the necessary maintenance. Not previously used or fire retardant coating fireproof paint processing. Building fire-resistant capacity depends on the construction of the stand or fall of fireproof performance, when the fire broke out its carrying capacity should extend a certain period of time, can make people safety evacuation and rescue supplies and extinguish fire. So exposed steel members brush fire retardant coating, steel fire-resistant time of 1.5 h steel column refractory time was 2.5 h, to make it conform to the requirements of the building code. Through practice have also found that in the steel for corrosion protection and fire prevention treatment for up to a year later, the steel structure of robustness is greatly enhanced, no rust, fire protection for building the user much a peace of mind, also prolong the service life of a lot of steel.
