for the past few yearsPVCAnti-corrosion tile with its anti-corrosion durable and easy to install and other advantages, in the roofing market is very popular, at the same time, a lot of low-quality anti-corrosion tiles have also flooded the market, as the average consumer how to safeguard their own interests and go to distinguish betweenPVCWhat about good or bad anti-corrosion tiles?
According to incomplete statistics nationwide there are thousands of large and small enterprises in the production and sales, licensed, unlicensed, impostor of a variety of useful high-weatheringPVCPowder, useful for ordinaryABS, PVC co-extruded or not co-extruded at all to produce! There is even a direct addition of recycled materials to produce, it is defensible.
Some people say: a shiny surface is good quality;
it has been said that:: Good quality if you can't break it with rubber pliers.;
Others say."It's good to have a car that doesn't break down;
There are others who say:Heavy handed good quality .........
From a scientific point of view good qualityWhat exactly is the standard of PVC anti-corrosion tile? Guangdong Gao Yi tell you:
Appearance of no obvious defects, with the above judgment criteria or touch, see, paw or pincer to judge the quality of good or bad, are not scientific!! It is a means to mislead consumers, belonging to the method of taking out of context and stealing concepts! 20 years ago to promote the PC sheet with the same method, with a 12-pound hammer can not break, so durable! Can't be broken ≠ durable! Do not rot belongs to the category of impact resistance, resistance to external forces (this is the advantage of PC, if the production of non-weathering PC, also do not rot but outdoor use 1-2 years will crack yellow); and durable is able to fight the sun's ultraviolet light, the two are completely different concepts! Of course, do not break and have UV coating, so the product outdoor certainly durable! So, to determine the quality of the product is not simply from a performance to judge, but from the product's various properties to a comprehensive judgment! Speaking of which, I believe you have a basic judgment!
The function of PVC anti-corrosion tile is anti-corrosion and durable and wind and rain protection, in the outdoor normal environment can be long时No cracking, no deformation, no brittleness, no rain leakage between,The warranty is also available for years! Gao Yi Brand PVCAnti-corrosion composite tile products,Outdoor use can be more than ten years! Among them, APVC anti-corrosion tiles have a service life of more than 15 years, and ASAPVC anti-corrosion tiles have a service life of more than 25 years.。
However, some manufacturers for the sake of immediate interests and disregard for the interests of consumers, in the thickness of the above cut corners, and some even add recycled material production. The use of such products less than two years will be deformed and cracked, recycled material to do the product or even use less than a few months will be cracked and leakage, thus seriously harming the interests of consumers!
Let's go back to the previous answer to the question posed by the client:
(1)Good surface brightness - belongs to the “bright” series, easy to cause “light pollution”, the cost is slightly lower than the “matte” series! The cost is slightly lower than the "matte" series! Due to bright, early fading will be faster, not recommended.
(2) Bite with rubber pliers can not be broken - the apparent phenomenon of good toughness! But weatherability to meet the requirements? If the weather resistance is poor easy to deformation leakage, leather flexibility is good enough, but can be used in the roof? Good toughness at the same time to ensure weather resistance.
(3) car pressure is not rotten --- this phenomenon is analogous to the rubber pliers bite constantly situation
(4) Heavier feel - the heavier the feel at the same thickness，The more inorganic fillers,The lower the plastic content, the cheaper the cost! The lower the protection factor for outdoor use! Why there are a lot of cheap tiles easy to crack after installation, is due to too much calcium powder filler!，And impact modifier additive andPVCPowder is too little, or a large number of recycled materials to produce, so that the toughness of the product is not enough, the product in the thermal expansion and contraction of the resulting“The ”internal stress“ is greater than the fracture strength of the product, but also the product is not at all ”protection factor" which leads to product cracking, high temperature will also appear deformation phenomenon!
Therefore, a product needs to be designed, process control, formulation ratio and other comprehensive factors to meet all the conditions of use, so that the product's comprehensive cost-effective high!!
Having said that, I believe that all of youreadersWe know what we're doing.！All of the above test methods are insufficient to account forPVC anti-corrosion tiles of good quality！So, how exactly do you as a consumer judge this?Gao Yi building materials tell you that there is no better way to judge the performance of building materials. Gao Yi building materials tell you there is no better way, only through the performance of the test in the laboratory in order to make a comprehensive judgment!！So, when consumers choose a product，Learn about the history, size and overall strength of the manufacturer.，More important is the culture and positioning of the company!
Conclusion:
(1) Judge the good and bad synthetic resin tile must be tested through the laboratory after its comprehensive performance in all aspects to make a correct judgment, from a performance to judge is not scientific and inaccurate.
(2) PVC anti-corrosion tile belongs to the “conscience of the product”, the company's history, scale, comprehensive strength, corporate culture and positioning, determines the positioning of the product and product quality.
(3) There is a good sense of quality but there is no professional and technical force and quantitative testing methods to monitor product quality, product quality is not stable.
