Abstract

The method of making the hollow section bar with wood chip or rice husk is that the humidity of at first wood chip or rice husk must not be sneaked into adhesive greater than 8%, and binder wt accounts for 3～10% of wood chip or rice husk weight, sends into extrusion modling in the make-up machine then.Need wood chip or rice husk heating are finished by the heater that is contained on the make-up machine in forming process, heating and temperature control through make-up machine extrusion profile continuously, is blocked according to required size between 150 ℃～250 ℃.The section bar of circle foreign side also had section bar cylindraceous in the section bar of extruding had.In the section bar of circle foreign side be combined into the non-load bearing wall that can be used for building industry behind the plate, section bar cylindraceous can be used for the coil paper core of paper-making industry.

Description

Make hollow section bar and production method with wood chip or rice husk

What the present invention relates to is a kind of with wood chip or rice husk manufacturing hollow profile and production method.

In daily life, wood chip or rice husk are often handled as industrial waste, usually can become the hidden danger of fire.People's great majority are wood chip or rice husk are acted as a fuel or to use after carbonization for many years.U.S. Pat 3574816 and Russian Patent SU-365064 have put down in writing a kind of method that adopts rice husk.This method is that rice husk is burnt to the ash content of extent of deterioration 30～70%, makes building block as a kind of additive with other material, and this method is be used after must be at first will rice husk handling and be not direct utilization.Reach by retrieval and consult both at home and abroad and relevant document, still find no same or analogous record with the present invention.

The objective of the invention is turns waste into wealth, and for building industry or other industry provide a kind of new material, has therefore invented and has thisly made hollow section bar and this production method with wood chip.

Particular content of the present invention and most preferred embodiment are as follows:

The method of making the hollow section bar with wood chip or rice husk is that the humidity of wood chip or rice husk must not be greater than 8%, wood chip or rice husk are put into mixer to be stirred, adding adhesive, adhesive while stirring is to add in the mixer equably after the sizing applicator atomizing, the applied amount of adhesive accounts for 3～10% of wood chip or rice husk weight, applies the wood chip behind the adhesive or rice husk stirs after feed appliance is delivered to extrusion modling in the make-up machine.Need in forming process wood chip or rice husk heating, heating wood chip or rice husk are finished by the heater that is arranged on the make-up machine, and heating-up temperature can be controlled between 150 ℃～250 ℃.The section bar of extruding continuously through make-up machine is blocked by the cropper length dimension as required that is installed in make-up machine extruder head front end.By the hollow section bar of the said method manufacturing of the present invention can be the hollow section bar of interior garden foreign side, also can be the hollow profile of garden tubular.

The hollow section bar of producing by method of the present invention in use can be with the bonding hollow sheet material that is assembled into of hollow section bar combination of interior garden foreign side, can be used for the non-load bearing wall of building industry after will this sheet material two sides decorating.The hollow section bar of garden tubular can be used for paper-making industry coil paper refill or plastics industry and the similar core of other industry.

Advantage of the present invention is:

1, turns waste into wealth, make full use of trade waste, new material is provided for building industry or other are industrial.

2, be used for the building industry non-load bearing wall and have sound insulation, insulation effect has in light weightly, is convenient to dismounting, reduces characteristics such as construction costs.

3, technology is simple, produces in enormous quantities with low cost, easy to utilize.

Claims

1, make hollow section bar and production method with wood chip or rice husk, the humidity that it is characterized in that wood chip or rice husk must not be greater than 8%, wood chip or rice husk are put into mixer to be stirred, add adhesive while stirring, adhesive is to add in the mixer equably after the sizing applicator atomizing, the applied amount of adhesive accounts for the 3-10% of wood chip or rice husk weight, apply the wood chip behind the adhesive or rice husk stirs after feed appliance is delivered to extrusion modling in the make-up machine, in forming process, need wood chip or rice husk heating, heating wood chip or rice husk are finished by the heater that is arranged on the make-up machine, heating-up temperature can be controlled between 150～250 ℃, through make-up machine extrusion profile continuously.Block by the cropper length dimension as required that is installed in make-up machine extruder head front end.

2, as claimed in claim 1ly making hollow section bar and production method with wood chip or rice husk, it is characterized in that the hollow section bar that said hollow section bar can be interior round foreign side, also can be hollow section bar cylindraceous.
