油漆做为木门工场加工的后期工艺，它的好坏间接影响着最初的利用效果。同时油漆成本也是木门成本上更大的部门之一。油漆的品种大致分为酚醛漆、醇酸漆、聚氨脂漆、硝基漆、聚脂漆(PE漆)及PU漆。此中酚醛漆和醇酸漆因为漆膜量感及附出力差，根本在拆修中裁减，大量利用的是硝基漆、聚脂漆及PU漆。
As the late processing technology of wooden door factory, the quality of paint directly affects the final use effect. At the same time, the cost of painting is also one of the largest parts of the cost of wooden doors. The types of paint are generally divided into phenolic paint, alkyd paint, polyurethane paint, nitro paint, polyester paint (PE paint) and PU paint.
硝基漆因为施工比力简单、合适手工操做，被大大都手工粉饰要木做利用，便其漆膜薄，手感欠好，效果不睬想。PU漆的长处是易打磨，加工过程省时省力，缺点是漆膜软，略微磕碰极易产生白影凹痕。假设在漆层中至少有一层是PE漆，就会大大减低那种可能。
Nitrocellulose paint is relatively simple in construction and suitable for manual operation. It is used by most of the manual decoration, but its paint film is thin, the feel is not good, and the effect is not ideal. PU paint has the advantages of easy polishing, time-saving and labor-saving processing.
PE漆(聚酯漆)的长处是漆膜硬，粉饰力强，通明度好，能更好地表示木皮纹理，缺点是难于打磨，加工过程费时吃力，绝大大都厂家不情愿摘用PE涂层。目前市场上90%的套拆木门利用聚脂漆，少数厂家摘用PU漆。
PE paint (polyester paint) has the advantages of hard film, strong covering power, good transparency, and better performance of wood skin texture. The disadvantages are that it is difficult to polish, and the processing process is time-consuming and laborious. Most manufacturers are unwilling to use PE coating.

一般来说，聚脂漆和PU漆都要颠末找色，三底两面等六道工序，有些品牌增加固化和施蜡工艺。因为成本(硝基漆8 15元/公斤，聚脂漆18 28元/公斤，PU漆43 65元/公斤)、加工手段及设备的问题，目前市场上90%的套拆木门利用聚脂漆，少数厂家摘用PU漆。
Generally speaking, polyester paint and PU paint have to go through six processes, including color finding, three bottoms and two sides. Some brands have added curing and waxing processes. Due to the cost (nitrocellulose paint 815 yuan/kg, polyester paint 1828 yuan/kg, PU paint 4365 yuan/kg).

油漆的抉择应重视8点
1、物理性能：PU开放式漆因为漆膜相对较薄，所以许多油漆消费厂家和利用厂家其实不重视其物理性能，如：冲击、硬度和柔韧性。柔韧性好的油漆经冷热轮回后漆膜不容易开裂，即便有略微的碰碰，油漆也不容易破损，相反则随便呈现以上问题。开放式的油漆如要兼顾到柔韧性及抗冲击性，得选用较好的素材，一些低价位的油漆厂为了逃求低成本会选用一些较差的素材，其油漆性能天然就达不到要求。
1. Physical properties: Due to the relatively thin film of PU open paint, many paint manufacturers and users do not pay attention to its physical properties, such as impact, hardness and flexibility. The paint film with good flexibility is not easy to crack after cold and hot cycles. Even if there is a slight collision, the paint is not easy to be damaged.
2、枯燥性能：开放式产物的工序较多，关于工场来说，每道工序之间的时间越短越好，所以油漆的枯燥性能就显得很重要。关于油漆厂家来说，进步通俗开放式油漆的干性其实不难，但关于有耐黄变要求的漆，干性相对要难，特殊是顶级耐黄变开放式漆。
2. Drying performance: open products have many processes. For factories, the shorter the time between each process is, the better. Therefore, the drying performance of paint is very important. It is not difficult for paint manufacturers to improve the dryness of ordinary open paint...
3、耐黄性：关于通明彩色及黑色的产物可选用通俗开放式油漆，但关于淡色、本质及白色产物则要选用耐黄变的产物。关于要求较高的产物必然要选用顶级耐黄变漆，顶级耐黄变产物目前市道上很少有厂家做得好，因为干性与耐黄性较难到达平衡。
3. Yellowing resistance: For transparent color and black products, common open paint can be selected, but for light color, natural color and white products, yellowing resistance products should be selected. For products with higher requirements, top yellowing resistant paint must be selected.
4、清晰度：通明类产物的通明度要高，因欧美风气产物特殊讲究木材纹理的清晰，对油漆的通明度要求较高。那里说的清晰度并非指底漆能否含粉或含粉料几，而是指油漆自己原素材的相溶性，相溶性差的产物，其油漆外看都是通明的，但漆膜干透后，油漆呈现发蒙不清晰的现象。
4. Clarity: The transparency of transparent products should be high. Because European and American style products pay special attention to the clarity of wood texture, they have higher requirements for the transparency of paint. The definition here does not refer to whether the primer contains powder or how much powder it contains.
5、渗入性：开放式油漆因为要求导管内和木门外表都要有一样的漆膜，故油漆的渗入性、润湿性就决定了整个开放板面的效果。假设润湿性差，则施工时导管很难流进油漆，导管四周会呈现油漆堆集，使导管显得很肥厚，天然无法得到称心的开放效果。
5. Permeability: open paint requires the same paint film inside the conduit and on the surface of the wooden door, so the permeability and wettability of the paint determine the effect of the entire open panel. If the wettability is poor, it is difficult for the conduit to flow into the paint during construction.
6、施工性：好的开放式油漆应可按一般通俗全封锁的产物喷涂办法停止施工，施工人员的喷涂习惯不需要做调整，并且若有返工，经返工后毛眼也不该填死。
6. Constructability: good open paint can be applied according to the normal full-closed product spraying method. The spraying habits of the construction personnel do not need to be adjusted, and if there is rework, the pores after rework should not be filled.
7、格丽斯：格丽斯是开放式产物中常用到的辅助产物，它可增加产物木纹的清晰度，调剂产物的条理感，许多厂家消费的格丽斯属于NC系列，用于PU开放式产物的色，常会呈现漆层脱落、发霉等现象，因而PU开放式应选用配套的PU格丽斯产物，但是PU格丽斯手艺含量很高，只要很少的油漆厂家能供给实正的PU格丽斯，木门厂家选用时应特殊重视那一点。
7. Grace: Grace is a commonly used auxiliary product in open products. It can increase the clarity of product grain and adjust the layering of products. Grace produced by many manufacturers belongs to the NC series, which is used for the color of PU open products. There are often phenomena such as paint peeling and mildew.
8、色精：常用的着色剂，固然较常用，但假设选用的色精不准确，则可能会有以下问题：①能否环保(重金属的含量能否超标);②耐光性能：每个厂家的色精产物耐光性都差别，同样的颜色有的耐光性有很大的区别。有的色精见光极易合成，那就是说本来的颜色会跟着时间的推移渐渐消逝，颜色会越来越淡。那就是为什么有的产物会与原则板的色差越来越大的原因，所以色精更好选正规油漆厂家配套产物。
8. Chromatin: common colorants, although more commonly used, if the selected color essence is incorrect, the following problems may occur: ① whether it is environmentally friendly (whether the content of heavy metals exceeds the standard); ② Light fastness: The light fastness of color essence products from each manufacturer is different, and the light fastness of some of the same colors is very different...
