在樂從鋼材市場(chǎng)中存在很多專門術(shù)語，對(duì)于外行來說難以理解，對(duì)于從業(yè)人員也是非常容易混淆，如果不是有深入的了解，很難理解類似工藝及材料的區(qū)別，比如pcm彩涂板和vcm覆膜板的定義和區(qū)別。

There are many special terms in the steel market of Lecong, which are difficult for amateurs to understand, and also very easy to confuse for practitioners. If not for in-depth understanding, it is difficult to understand the differences between similar processes and materials, such as the definition and difference of pcm color coating board and vcm coating board.

01

▲pcm預(yù)涂板

▲ pcm pre-coated board

Pcm（Prepainted steel sheet）即彩色預(yù)涂鋼板，主要是采用輥涂方式在金屬卷材上涂上一層或多層涂料再經(jīng)高溫烘烤而成的復(fù)合材料。

Pcm (Prepainted steel sheet) is the color pre-coated steel plate, mainly using the roller coating method on the metal roll coated with one or more layer of coating and then through high temperature baking of the composite material.

pcm彩涂板特點(diǎn)：預(yù)涂板除了具有單色、珠光、花紋等裝飾效果，還同時(shí)具有色彩豐富、生產(chǎn)效率高、周轉(zhuǎn)速度快、環(huán)保無污染的優(yōu)點(diǎn)。但其相對(duì)平整度較覆膜板差，且顏色效果比較單一，不適用于高端冰箱的面板，主要是側(cè)板的使用。

Features of pcm color coating board: pre-coating board in addition to monochrome, pearl, pattern and other decorative effects, but also has the advantages of rich color, high production efficiency, fast turnover speed, environmental protection and no pollution.But its relative flatness is poor than the film board, and the color effect is relatively single, not suitable for the panel of high-grade refrigerator, mainly the use of the side board.

▲vcm覆膜板

▲ vcm coated plate

Vcm即PET/PVC貼膜彩色鋼板，通常是指將鍍鋅基板進(jìn)行表面處理后涂敷(輥涂)或粘結(jié)有機(jī)薄膜并烘烤而成的產(chǎn)品，又稱PET/PVC貼膜彩色鋼板。

Vcm is PET / PVC film color steel plate, usually refers to the galvanized substrate surface coating (roller coating) or bonding organic film and baking product, also known as PET / PVC film color steel plate.

目前所用的PVC膜有光亮膜和啞光膜。

The PVC films used currently have shiny and matte films.

光亮膜是指表面光澤度較高的膜，是在PVC膜表面再復(fù)合了一層PET膜，其本身就是一種復(fù)合膜。

Bright film refers to the film with high surface gloss, which is a composite PET film on the surface of the PVC film, which is itself a composite film.

啞光膜是指表面光澤度較低的膜，膜整體為PVC材質(zhì)，在其表面有一些壓紋等紋理效果。

Matute film refers to the film with low surface gloss, the whole film is PVC material, on its surface has some embossing and other texture effects.

vcm覆膜板特點(diǎn)：具有靚麗的外觀、優(yōu)異的加工性能、耐腐蝕耐刮傷等優(yōu)點(diǎn)，且可實(shí)現(xiàn)低光到高光、精美圖案和珠光閃爍效果。表面的膜材具備可印刷等特殊處理的特性，可表現(xiàn)出多種色彩及紋理效果，如木紋、石紋、磚瓦紋、皮革紋等。

Features of vcm coated board: with beautiful appearance, excellent processing performance, corrosion resistance and scratch resistance, and can achieve low light to high light, exquisite pattern and bead light flashing effect.The film material on the surface has the characteristics of printing and other special treatment, which can show a variety of colors and texture effects, such as wood grain, stone grain, brick and tile grain, leather grain, etc.

pcm彩涂板和vcm覆膜板的定義和區(qū)別：

Definition and difference between pcm painted plates and vcm coated plates:

在定義上：

pcm彩涂板和vcm覆膜板的定義和區(qū)別是預(yù)先涂裝金屬板，將pcm用涂料預(yù)先涂裝到金屬板上，再將涂裝后金屬板切割成型，最后組合成產(chǎn)品。

Vcm面板是金屬覆膜板，就是在金屬板表面覆上pvc還有pet的薄膜，這樣就可以在薄膜上印各式花色。

On definition:

The definition and difference between pcm color coating board and vcm coating board is precoating metal plate, pcm coating to metal plate, then the metal plate is cut and formed, and finally combined into a product.

Vcm panels are metal coated plate, which is the surface of the metal plate covered with pvc and pet film, so that various colors can be printed on the film.

在特性上：

Vcm板為覆膜板，pcm為彩涂板，Vcm板表面十分光滑平整，表面彩色效果絢麗。pcm相對(duì)平整度較差，顏色效果單一。

On features:

Vcm board is film covering board, pcm is color coating board, Vcm board surface is very smooth and flat, the surface color effect is gorgeous.The pcm is relatively less smooth and has a single color effect.

在價(jià)格上：

Vcm覆膜板價(jià)格較貴，pcm為彩色預(yù)涂板材，表面為家電環(huán)保油漆，價(jià)格相對(duì)于Vcm覆膜板較為便宜。

Vcm film plate price is more expensive, pcm is color pre-coated plate, the surface is home appliances environmental protection paint, the price is cheaper compared to Vcm film plate.
