4. Conclusion
Binderless boards were manufactured from rice straw by hotpressing
and measured for IB, TS and WA in order to evaluate the
morphological effect on the properties of the board. For the morphological
effect, we examined the influence of particle size and
morphological part. Our conclusions are summarized as follows:
1. Binderless boards were successfully manufactured from rice
straw when the raw materials were ground until they passed
through 1-mm screen.
2. For the effect of the morphological part, the IB of boards made
from stem powder was the highest, followed by leaf blade powder
and leaf sheath powder. IB increased with decreasing ash
and silica contents. Trichomes and wart-like protuberances on
the epidermis of rice straw might inhibit self-bonding between
particles.
3. The water resistance of binderless boards made from rice straw
was relatively high regardless of low IB. Wax-like substances
on the epidermis of rice straw contributed the water resistant
properties of particles.
4. This study suggested that binderless board made from rice straw
was one of the best methods to fully utilize the potential of rice
straw, in contrast to boards made with UF resin that suffer from
low compatibility between the resin and wax-like substances on
the epidermis of rice straw.

4. Gevolgtrekking
Binderless planke is gemaak van rys strooi deur hotpressing
en gemeet vir IB, TS en WA ten einde die evalueer
morfologiese uitwerking op die eienskappe van die raad. Vir die morfologiese
effek, ons ondersoek die invloed van deeltjiegrootte en
morfologiese deel. Ons gevolgtrekkings word soos volg opgesom:
1. Binderless planke was suksesvol vervaardig van rys
strooi wanneer die grondstowwe is gemaal totdat hulle geslaag
deur 1-mm skerm.
2. Vir die effek van die morfologiese deel, die IB van planke gemaak
van stam poeier was die hoogste, gevolg deur blaarskyf poeier
en blaarskede poeier. IB toegeneem met dalende as
en silika inhoud. Trigome en vrat-agtige uitsteeksels op
die epidermis van rys strooi dalk self-binding tussen inhibeer
deeltjies.
3. Die water weerstand van binderless planke gemaak van rys strooi
was relatief hoë ongeag lae IB. Wax-agtige stowwe
op die epidermis van rys strooi bygedra die waterbestand
eienskappe van deeltjies.
4. Hierdie studie het voorgestel dat binderless raad gemaak van rys strooi
was een van die beste metodes om die potensiaal van rys ten volle te benut
strooi, in teenstelling met planke gemaak met UF hars wat ly aan
lae verenigbaarheid tussen die hars en was-agtige stowwe op
die epidermis van rys strooi.
