Claims (1)
본문에 상술한 바와 같이 액상요소 수지를 분무 건조장치에서 건조하여 얻은 분말요소수지(수지분 90%-98%)를 천연건조상태의 셀루로즈 칩(목재파티클, 톱밥, 볏짚, 왕겨, 건초, 낙엽 등)과 잘 혼합하여 소정의 몰드에서 성형시킴에 있어서 분말요소수지 1부에 대하여 목재파티클 4-7부의 비율로 혼합하여 성형시켜서 가압시 온도는 175℃-190℃로 유지하고 압력은 보드단위 면적당 25kg/㎠-33kg/㎠으로 가압시키면서 두께 1mm당 약 10초의 열압시간을 줌으로서 표면이 매끈한 성형파티클 보드를 제조함을 특징으로 하는 분말요소수지와 식물성 셀룰로즈 칩을 사용한 성형파티클 보드의 제조방법.As described above, the powdered urea resin (90% to 98% resin) obtained by drying the liquid urea resin in a spray drying apparatus was subjected to cellulose chips (wood particles, sawdust, rice straw, rice husk, hay, fallen leaves) in a natural dry state. Etc.) to mix in a predetermined mold and mix in a ratio of 4-7 parts of wood particles to 1 part of powdered urea resin, and to be molded. Pressurized temperature is maintained at 175 ℃ -190 ℃ and the pressure per board area A method of producing a molded particle board using a powder urea resin and vegetable cellulose chips, which is characterized by producing a molded particle board having a smooth surface by giving a thermal pressure time of about 10 seconds per 1 mm in thickness while pressing at 25 kg / cm 2 -33 kg / cm 2.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
