胡博士|關(guān)于膚感技術(shù)的討論

由于膚感板，有良好的觸覺和視覺效果，已經(jīng)成為家具和裝飾材料行業(yè)應(yīng)用的一個(gè)熱點(diǎn)。目前膚感效果一般可以由四種加工技術(shù)得到：

The good tactile and visual effects of super matte board has become a hot spot in furniture and decorative materials industry. At present, the super matte effect can be generally obtained by four processing technologies:

一、膜壓技術(shù)Membrane pressure technology

在做好底漆的工件上，輥涂UV面漆，用膚感膜壓壓平膚感面漆，通過UV光源固化后，把膜揭掉，就得到膜壓的膚感產(chǎn)品。

On the work piece with primer, apply UV top coating on roller, press and flatten the top coat with super matte film, and remove the film after curing with UV light source to get the super matte sensitive product with film pressure.

膜壓技術(shù)，也只能加工平面產(chǎn)品。并且由于膚感膜的微觀結(jié)構(gòu)限制，這類產(chǎn)品，膚感的時(shí)效性，在一定條件下，會(huì)有所限制。目前，在國內(nèi)的應(yīng)用，膚感膜都是一次性使用，導(dǎo)致運(yùn)營成本也偏高。

Membrane pressing technology can only process plane products. And because of the limitation of the micro structure of the super matte sense film, the timeliness of the sense of this kind of products will be limited under certain conditions. At present, in domestic applications, the super matte film is disposable, resulting in high operating costs.

二、涂料技術(shù)Coating technology

目前，自干型油漆（ＰＵ，水性），都能通過油漆配方，來實(shí)現(xiàn)膚感效果。ＰＵ膚感漆較早就已經(jīng)實(shí)現(xiàn)；水性膚感漆，國內(nèi)已經(jīng)有好幾家油漆廠能夠提供。

At present, self drying paint (PU, water-based) can achieve super matte feeling effect through paint formula. PU super matte sensitive paint has been realized earlier; water-based super matte paint has been provided by several paint factories in China.

三、準(zhǔn)分子燈固化技術(shù) Curing technology of excimer lamp

1、工作原理Principle

來自于德國的IOT公司創(chuàng)造了172納米的UV固化設(shè)備(EXCIMER)，并具有獨(dú)特的性能，堪稱UV固化技術(shù)的“黑科技”。

IOT company from Germany has created a 172 nm UV curing equipment (EXCIMER) with unique performance, which can be called the "extreme high technology" of UV curing technology

UV涂料配方中的丙烯酸酯雙鍵在吸收172納米紫外光后，可生成自由基而可以無需光引發(fā)劑。同時(shí)172納米UV的穿透深度僅為100到500納米，因此涂料只有表面極薄的一層被固化。這一薄層的聚合和交聯(lián)，會(huì)發(fā)生收縮而形成不光滑的表面，并漂浮在未固化的下層液體上，達(dá)到表面啞光的效果。不過這個(gè)固化需要在氮?dú)猸h(huán)境下進(jìn)行，使操作環(huán)境的氧氣濃度低于100ppm。后續(xù)再采用常規(guī)UV或者電子束進(jìn)行完全固化。

After absorbing 172 nm UV light, the acrylate double bond in the formulation of UV coating can generate free radicals without photoinitiator. At the same time, the penetration depth of 172 nm UV is only 100 to 500 nm, so only a very thin layer on the surface of the coating is cured. The polymerization and cross-linking of this thin layer will shrink to form an unsmooth surface, and float on the uncured lower liquid to achieve the surface matte effect. However, this curing needs to be carried out in nitrogen environment, so that the oxygen concentration in the operating environment is lower than 100ppm. After that, conventional UV or electron beam is used for complete curing.

這種消光的方法由于不需要使用消光劑，因此被稱為“物理消光”。同時(shí)172納米下表面發(fā)生的聚合和交聯(lián)可提供高的表面硬度及高涂料密度。

This method of extinction is known as "physical extinction" because it does not require the use of a matting agent. At the same time, the polymerization and cross-linking on the lower surface of 172 nm can provide high surface hardness and high coating density.


2、工藝及設(shè)備Process and equipment

此種技術(shù)目前只能用于平面產(chǎn)品。在做好UV底漆的工件上，輥涂UV膚感面漆，經(jīng)過LED的深層固化，經(jīng)過超啞UV設(shè)備，再經(jīng)過常規(guī)UV固化設(shè)備，就可以得到膚感產(chǎn)品。

At present, this technology can only be used for plane products. On the work pieces with UV primer, apply UV super matte topcoat by roller, deep curing by LED, ultra dumb UV equipment and conventional UV curing equipment to get super matte products.

目前，能提供整套超啞UV設(shè)備和技術(shù)的，有德國的IOT公司（整機(jī)采購價(jià)格大約￥100萬多一點(diǎn)）；能提供核心部件和技術(shù)有德國的IST公司（光源及控制系統(tǒng)、氮?dú)饪刂葡到y(tǒng)及裝置），國內(nèi)現(xiàn)在能夠提供超啞UV設(shè)備要不然就是購買IST公司的整機(jī)核心部件在國內(nèi)拼裝，要不然就是直接購買IOT公司整機(jī)設(shè)備。

At present, IOT company in Germany can provide a complete set of super matta UV equipment and Technology (the purchase price of the whole machine is about ￥ 1 million); IST company in Germany can provide core components and Technology (light source and control system, nitrogen control system and device), and now China can provide super matta UV equipment, otherwise, it is to purchase the whole machine core components of IST company for assembly in China, or However, it is to directly purchase IOT complete equipment.

3、特點(diǎn)分析及介紹Characteristic analysis and introduction

①優(yōu)點(diǎn)：和PU、水性等膚感漆相比，這種膚感產(chǎn)品更耐刮、抗污、防指紋、可修復(fù)等。

Advantages: Compared with PU, waterborne and other super matta paints, this skin-sensitive product is more scratch resistant, stain resistant, fingerprint resistant and repairable.

②不足：設(shè)備的一次性投資成本高，運(yùn)營成本較高，只能加工平面產(chǎn)品（如果大板的平整度不夠，都會(huì)出現(xiàn)次品）。

Disadvantages: The one-time investment cost of equipment is high, the operation cost is high, can only process planar products (if the flatness of large board is not enough, will appear defective).

A.?準(zhǔn)分子燈的標(biāo)準(zhǔn)工作壽命正常3000小時(shí)，也容易因保養(yǎng)維護(hù)不當(dāng)導(dǎo)致?lián)p壞，一支進(jìn)口光源的價(jià)格要5-７萬多人民幣左右（不同品牌會(huì)有差異）。

A. The standard working life of the excimer lamp is normal 3000 hours, and it is also easy to be damaged due to improper maintenance. The price of an imported light source is about 50,000-70,000 RMB (different brands will have differences).

B.?設(shè)備運(yùn)行時(shí)，需要大量的高純氮?dú)狻Ｒ话阏９ぷ?，需要純度?9.999%氮?dú)?0立方／小時(shí)。

B. A large amount of high-purity nitrogen is required for the operation of the equipment. Normal operation requires a purity of 99.999% nitrogen of 20 cubic meters per hour.
