冰箱底板背板用pcm彩涂板0.35mm厚非钝化无花镀锌板家电外板彩涂基板 ...

目前，冰箱所用的侧板、后板、后底板大部分为金属板材，该金属板包括金属喷涂板、镀锌板、镀铝锌板等，另外还有一小部分的后板、后底板为纸板或中空板，也称钙塑板或瓦楞纸板。其中，金属板材的强度高、易成型，但价格较高。

At present, the refrigerator side board, back board, rear bottom board is mostly metal board, the metal plate includes metal spray board, galvanized sheet, there are a small part of the back plate, back bottom plate is cardboard or hollow board, also called calcium plastic board or corrugated board. Among them, the strength of the metal plate is high, easy to form, but the price is higher.

市面上质量好的的冰箱，底板与背板采用镀锌钢板制成，耐高温耐腐蚀，防火防冲击，同时又具有良好的保温性能，真材实料。

The refrigerator with good quality on the market, the bottom and back plate are made of galvanized steel plate, high temperature and corrosion resistance, fire prevention, at the same time has good insulation performance, real material.

冰箱底板一直使用的是厚度0.3mm的镀锌钢板，这是因为镀锌板有良好的抗腐蚀能力。冰箱完成发泡过程之后，镀锌钢板的主要作用就是防止外界水蒸气等因素引发钢板生锈，防止内部的发泡料腐蚀钢板，据对冰箱各零部件所作的匹配可靠性调查，冰箱的使用寿命平均为10年左右，而镀锌钢板在镀锌量为350克/平方米（单面）时，在室外的寿命（生红锈），约为15~18年，冰箱作为家庭内置消费品，它的使用环境远远优越于室外，类比可知，同样的镀锌钢板使用在冰箱上，寿命应该高于18年，远高于冰箱的整体使用寿命。

The refrigerator floor has been used in the thickness of 0.3mm galvanized steel plate, because the galvanized plate has good corrosion resistance. Refrigerator after the foaming process, galvanized steel plate's main role is to prevent external factors such as water steam steel rust, prevent internal foam corrosion steel, according to the matching reliability survey, the service life of the refrigerator on average 10 years, and galvanized steel plate in galvanized amount of 350 grams / square meters (single side), in the outdoor life (red rust), about 15~18 years, the refrigerator as a family built-in consumer goods, its use environment is far superior to outdoor, analogy, the same galvanized steel plate used in the refrigerator, life should be higher than 18 years, Far higher than the overall service life of the refrigerator.
