    如何提高塑料托盤的耐熱性大家知道嗎?

    來源:http://www.zywygg.com 發(fā)布時間:2020-04-06

      溫度是逐漸升高的,如果經(jīng)常暴露在陽光下,對塑料托盤的壽命會有嚴(yán)重的影響。其實提高托盤的耐熱性就足以延長托盤的使用時間,那么如何提高托盤的耐熱性呢?托盤廠家有話要說。
      The temperature is gradually rising, if often exposed to the sun, the life of plastic tray will be seriously affected. In fact, improving the heat resistance of pallets is enough to extend the use time of pallets, so how to improve the heat resistance of pallets? Pallet manufacturers have something to say.
      熱塑性分子的結(jié)構(gòu)是線性結(jié)構(gòu),在受熱的情況下軟化或熔化的現(xiàn)象,可以模壓成一定的形狀,冷卻后會變硬;但在加熱到一定程度后優(yōu)先重新軟化,這個過程可以重復(fù)。

      The structure of thermoplastic molecules is a linear structure, which softens or melts when heated. It can be molded into a certain shape, and it will become hard after cooling. However, when heated to a certain degree, it will soften again first, which can be repeated.
      塑料托盤廠家熱塑性成型工藝相對簡單,可以實現(xiàn)連續(xù)生產(chǎn),且機械強度高,所以發(fā)展速度相對較快。
      The thermoplastic forming process of plastic pallet manufacturers is relatively simple, can realize continuous production, and has high mechanical strength, so the development speed is relatively fast.
      塑料托盤在生產(chǎn)時,加熱到一定程度后加入一定的固化劑即可硬化成型,再加熱時不會出現(xiàn)發(fā)軟或變形的現(xiàn)象。但是有些材料在這樣做之后就不能回收了。以上是塑料托盤廠家一直記得的關(guān)于如何提高托盤的耐熱性,希望對你有所幫助。
      In the production of plastic pallet, when it is heated to a certain degree, it can be hardened and formed by adding a certain curing agent. When it is reheated, it will not be softened or deformed. But some materials cannot be recycled after doing so. These are the plastic tray manufacturers always remember about how to improve the heat resistance of the tray, hope to help you.
      以上是托盤廠家為大家介紹的相關(guān)內(nèi)容,想要了解更多內(nèi)容,歡迎訪問網(wǎng)站:http://www.zywygg.com
