pcm彩涂板面漆即在鍍鋅板表面涂裝油漆，也稱卷材面漆，是一種用于鍍鋅板表面涂裝，起到裝飾和保護作用的油漆。它即要求與底漆有優(yōu)良的附著力，又能美化產品視覺效果還能保護底材不受環(huán)境等因素影響使用時間。目前卷材涂料所使用的面漆，其配方一般采用以下幾種原料普通飽和聚酯、普通氨基樹脂、顏料、助劑、溶劑。上述原材料配料后按常規(guī)卷材涂料生產工藝，經分散、研磨、調漆、灌裝等工序加工而成。
The pcm color coated plate surface paint is in the galvanized plate surface coating paint, also known as roll material surface paint, is used for galvanized plate surface coating, decorative and protective paint.It requires excellent adhesion with the primer, and can beautify the product visual effect can also protect the substrate from the environment and other factors affect the use time.At present, the surface paint used in coil coating, its formula generally uses the following raw materials ordinary saturated polyester, ordinary ammonia resin, pigment, additives, solvent.The above raw material ingredients according to the conventional coil coating production process, through the dispersion, grinding, painting, filling and other processes and processed.
pcm彩涂板面漆種類在硬度、柔韌性、附著力、耐久性等方面存在差異。聚酯是目前使用量大的涂料，耐久性一般，硬度韌性好，價格適中。硅改性聚酯耐久性、光澤、顏色保持性高，但韌性略降低，高耐候性聚酯性價比較高。聚偏氟乙烯耐久性優(yōu)異，韌性好，但硬度低，可供顏色少，價格高。彩涂板的面漆主要根據(jù)用途、使用環(huán)境腐蝕性、使用壽命、耐久性、加工方式、變形程度影響。
The types of pcm color finish paint are different in hardness, flexibility, adhesion, durability and so on.Polester is the current large amount of paint, general durability, hardness and toughness, moderate price.Silicon modified polyester durability, luster, color retention, but slightly reduced toughness, high weather resistance polyester cost performance.Polyvinylidene fluoride has excellent durability, good toughness, but low hardness, less color, high price.The surface paint of color coating board mainly depends on the use, use environment corrosion, service life, durability, processing method and deformation degree.
選擇底漆重要的因素有兩個：一是考慮底漆和面漆以及面漆和基板附著力，另一個是底漆提供涂層的耐蝕性。在這方面，環(huán)氧樹脂是選擇順位。考慮到靈活性和防曬能力，還可以選擇聚氨酯底漆。背面涂層的選擇是，如果使用狀態(tài)彩涂板作為單板，則選擇雙結構。一種是背面的底漆，另一種是背面的油漆。底漆是與正面相同的品種，外皮選擇淺色滌綸層。例如白色。如果彩涂板使用狀態(tài)是復合板或夾層板，則可以在背面涂上粘合性和耐蝕性好的環(huán)氧樹脂。
There are two important factors to choose the primer: one is to consider the primer and primer and primer and substrate adhesion, and the other is that the primer provides the corrosion resistance of the coating.In this respect, the epoxy resin is the chosen shun.Also choose a polyurethane primer for flexibility and sun protection.The choice of back coating is to select a dual structure if a status color coating is used as a veneer.One is a primer on the back, and the other is a paint on the back.The primer is the same variety as the front, the skin of a light polyester layer.For example, white.If the color coating plate is a composite plate or sandwich plate, the back can be coated with epoxy resin with good adhesion and corrosion resistance.
