日本开夫拉希托公司利用英国的“抄纸法”技术,开发出一种由短切玻璃纤维纱和聚丙烯粉末组成的新型板材“KP-板”。 “KP-板”的主要特点是受热会自动膨胀。其生产工艺流程:短切玻纤纱和聚丙烯粉末在分散槽中分散、混合→抄取→脱水、干燥→卷取→冷、热压加工→纵切→制品。分散槽中的泡沫液体能使玻纤纱均匀分散成单根纤维。 Kauf Rashito of Japan used the “papermaking” technique of the United Kingdom to develop a new type of plate “KP-board” composed of chopped glass fiber yarn and polypropylene powder. The main feature of “KP-board” is that it will automatically expand when heated. Its production process: chopped glass fiber yarns and polypropylene powders are dispersed and mixed in the dispersion tank →→copy→dehydration, drying→coiling→cold and hot pressing→slitting→products. The foam liquid in the dispersion tank can uniformly disperse the glass fiber yarn into a single fiber.
