2017-3-27 10:50:47
Coating with oxidative crosslinking agent,Oxidation: narrowly, oxygen and other elements of the chemical reaction occurs, referred to as oxidation, is also a kind of important chemical unit process. Generalized oxidation, refers to the material loss of electrons (higher oxidation number) process.
Steel tube with powder coating crosslinked agent application
Should use the pollution-free source of heat for uniform heating pipe. Preheat temperature should be 200 + 10 ℃.
According to the procedure qualification test, anti-corrosion coating technology in coating layer.
The crosslinked coating should be in 200 ℃ heat preservation crosslinking 60 minutes.
Crosslinked coating after air cooling or water cooling method should be adopted.
The polyurethane coating waterproof layer construction process between wei yu
Generally should be equipped with an electric mixer (0.3 0.5 KW power, 200-500 r/min), stirring barrels (volume 10 l), the paint bucket (3 l), plastic or rubber scraper, roller brush, paint brush, spring balance, dry powder fire extinguishers, etc.
Besmear brushs the waterproof layer of the surface of the base, the dust, debris, etc must be clean, surface residue mortar lumps and highlights shall be razed and sweep, plaster, no, should be put into a circular arc or obtuse Angle of Yin and Yang.
Besmear brushs the waterproof layer of surface should be kept dry at the grassroots level and smooth, firm, shall not be free drum, cracking and defects such as sand.
In leveling layer of floor drain, pipe, outlet, sanitary ware roots (edge), to head. Slope comply with the design requirements, the parts must be installed firmly, embedded seal tightly. After check and accept.
Highlight the tube of the ground, floor drain, the drain of root, the Yin and Yang Angle details, should first be supplemented with additional layer, brush after the bottom of the polyurethane adhesive, through inspection and through concealed engineering acceptance.
All kinds of materials used for the waterproof layer, base treatment, xylene, etc are flammable items, storage and preservation to stay away from fire, construction operation, should be strictly forbid fireworks.
Waterproof construction may not be on a rainy day, windy day, winter construction of environment temperature should be not less than 5 ℃.
Operating process: clean up - details of basic level surface to make glue, besmear to brush glue (cold) base oil - details attached middle construction - the first time and the second time coating and coating to third time coating waterproof layer construction, the waterproof layer
A test to cover ACTS the role of surface, waterproof layer second acceptance test and waterproof layer
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Raw material ：
TDA industrial, Sichuan production
Ethylene (Et) polymer grade, Shanghai production
TEA industrial imports
A reagent grade additives
Before construction, waterproof layer should be the primary surface dust and other debris swept away, and use wet cloth clean to brush one more time.
Besmear brushs the waterproof layer of the surface of the base, can not have bumpy, loose, empty drum, sand, cracking and other defects, the moisture content is generally not more than 9%.
Besmear to brush glue (equivalent to cold priming oil) :
Dispensing glue, first to add a and b material polyurethane xylene, ratio of 1:1. 5-2 cooperate mix (weight ratio), make the amount shall be determined according to specific situation, unfavorable and overmuch.
Brushing glue, will be effected according to the law on preparation, good glue mixture evenly with the roller surface at the grassroots level, besmear brushs the amount of 0.15-0.2 kg/m2, with normal temperature season after 4 h later, feel is not sticky, can do the next working procedure.
Paint stick on the worm, as far as possible while picked will bug when paint did not work, and then gently with a little of the paint brush surface mending. If the paint has dried, then shall the paint film to harden again eliminate small bug, such ability won't make a terrible mess on the surface.
Lacquer timber surface gives heavy blackening, may is knag going up qi qian was not sealed, classics sun is basked in, knag be heated, resin from knag wipes out. Right now usable scraper scrape off the paint, to with burnish of fine sand paper next after showing knag, seal knag with the lacquer that seal a section, wait for dry after appearing, go up afresh again lacquer.
