First, the history of the development ceiling
1, the first generation of products for gypsum board, mineral wool board
Gypsum board gypsum as the main material, adding fiber , bonding agents , modifiers, by mixing repression, drying.
Advantages : easy styling, low price
Disadvantages: easy to scrub a single color , and easy to change , installation complexity .
2, the second took the PVC
Full name Polyvinylchlorid, the main ingredients of PVC , bright color , corrosion-resistant , durable, due to the increase of the plasticizer , anti-aging agents of some toxic auxiliary materials in the manufacturing process to enhance its heat resistance, toughness , extend and so on.
Advantages: easily flammable, high strength , resistance to climate variability and excellent geometric stability, oxidants , reducing agents and strong acids have a strong resistance.
Disadvantages: can be concentrated oxidizing acids such as concentrated sulfuric acid, concentrated nitric acid corrosion and does not apply and aromatic hydrocarbons, chlorinated hydrocarbons in contact situations ; not environmentally friendly, and easy to change , poor oxidation resistance , no moisture, no fire .
3, the third generation of metal ceilings
Aluminum ceilings are commonly used in aluminum ceiling : the use of aluminum or aluminum alloy material for the substrate, and then made its surface after different surface treatment process processing.
Advantages: fire, moisture , acid, anti- smoke , easy to clean , environmentally friendly, recyclable , rich colors.
Cons: Price is a little high compared to other materials .
Second, the development prospects of smallpox Lvkou
Because Lvkou plate and more flowing lines , rich colors, good appearance , more fire, moisture, easy to install , easy to clean features , designers and customers according to the color of the furniture and flooring colors to choose ceiling, earth 's welcome by the consumer , has been recognized by the world. From the ceiling gypsum board , mineral wool board , PVC, aluminum buckle development has been quite a long time . Spray only when Lvkou early advent of plate , and then roll back the development of film , ( which film used for home improvement, ) this film now on the market for the PVC film , produced in Japan, emerged in a PET film , and more environmental protection, this seems to Lvkou prospects in the coming years is very good .
Third, smallpox brands on the market
Lvkou many manufacturers on the market today , in the supermarket , the main foreign brands , " the Dutch music Sloan ," U.S. " Simon" , well-known brands are " rogue Thai ", " XAC " and so on . In fact, most of the so-called imported brands of imported technology and imported production lines, their land and raw materials production plants are in the country .
Fourth, the major determinant of Lvkou quality, price positioning
Aluminum material for ceilings are aluminum, aluminum impossible . However, due to the different resulting in different mechanical properties of aluminum alloy , the material currently used for the smallpox aluminum alloy content of approximately divided into five grades :
First grade : aluminum-magnesium alloy , while containing some manganese , the biggest advantage of this material is a good antioxidant capacity, and because there is manganese content , and therefore has a certain strength and stiffness , is the best material to make smallpox .
Second grade : aluminum-manganese alloy , the material strength and stiffness slightly better than aluminum-magnesium alloy . But slightly lower antioxidant capacity of aluminum-magnesium alloy . If both sides protective treatment , basically solved the antioxidant capacity is better magnesium alloy good shortcomings.
Third grade : aluminum, manganese alloy , and less magnesium content . So its strength and stiffness were significantly lower magnesium alloy and aluminum-manganese alloy . Because of its soft, easy to process , as long as a certain thickness to meet the basic requirements of smallpox basic flatness . But it was not as good antioxidant capacity aluminum-magnesium alloy and aluminum-manganese alloy . And processing and transportation and installation process easy deformation.
Fourth grade : ordinary aluminum alloy, the mechanical properties of this material is not very stable.
Fifth grade : This board is the raw material of aluminum melting plant will be tied into aluminum ingots , do not control the chemical composition . Because the chemical composition of control, the performance of these materials is very unstable , resulting in severe uneven surface of the product , product deformation, and easily oxidized .
From the above there are several grades of raw materials of points , we can easily analyze each of the ceiling after forming quality assurance. The best Lvkou , their main raw materials are used in the aluminum -magnesium alloy plate Southwest Ruimin Aluminum and aluminum -manganese alloy plate . Now many people think that the thicker plate like , there are several kinds of raw materials through the above analysis we can know , in the case the same raw material , then the better the thicker the plate, but the case of the fifth grade plate , then thick is not. Another on the surface treatment, some manufacturers of raw materials have not reached a certain thickness, but the thickness of this statement in order to pursue , in the surface treatment, the more spray a layer of paint . Ordinary consumers buy Lvkou the original plate material can not have a good understanding of the easiest way to hand the feeling of strength and hardness of aluminum .
V. Analysis of surface treatment
Currently ceiling surface treatment are: film , roller, spray three.
Currently coating material is good "LG" Korean company's products , the film prior to smallpox, is mainly used for refrigerators, washing machines and other household appliances . After years of tests, its performance is stable , fully guaranteed commitment of fifteen years do not change color . Now the market has a lot of ceiling surface treatment also called film , but the film is a country , after forming plate called laminating film board. There is a pearl panels , film faced plywood surface looks similar, it simply can not film , it is only when the electrostatic spraying , in advance plus pearl powder spraying paint inside . This plate prone to color, generally two or three years will change color , paint chips .
Roll plate is coated with primer and paint the front , back painted composite metal panels.
The first generation of products : Spray plate surface treatment process is as follows :
Semi-finished products - oil - Cleaning - chromium - drying ( dry ) - electrostatic powder coating - curing , cooling - down pieces and test - packaging and storage .
Market better spray plate surface using " Akzo " Paint Co. provided " epoxy " Electrostatic powder coating adhesion a gloss of 18 degrees , no color, no bubbles, no plot particles , weather resistance ( indoor 10 )
Good spray plate before spraying the surface after passivation, the surface with a sharp blade to any part of the planned cross- small cell 1MM * 1MM , using medical tape sticky tear , the coating does not fall off , and from washing 100 times , the surface without damage.
Second -generation products : roller plate surface treatment process is as follows :
Roll plate has paint, primer , paint the back , back painted mainly played antioxidant, make it last longer .
Semi-finished products - the machine - shaping - parts and tested under - packaging and storage .
Roll plate surface uniform, smooth , seamless coating, significant shrinkage defects , scratches, shedding . But the surface bubbles , pits , inclusions and other trace defects, which is a normal phenomenon .
