Abstract

The present invention relates to a production technology of making fiberboard by using a sunflower stem as a main raw material, which belongs to the class of building materials. A product of the production technology is used for making furniture and constructing houses, partition walls, etc. The present invention aims to supplement the requirement of a market for lumber, and enlarges the source of the raw material of an artificial board; the sunflower stem teeming on a local is adopted as the raw material; a traditional technology for making fiberboard and a formulation are changed for making hard fiberboard conforming to national standards GB1923-80.

Description

Fibreboard made of sunflower stem

The present invention is a building material, is to be the production technology of main raw material manufacturing fiberboard with the sunflower bar, and its product is used to make furniture and builds house partition wall etc.

Current timber day is becoming tight, and along with the development of society, the raising of living standards of the people more and more increases the requirement of timber.Although some wood-based plates are also arranged on the market, as fiberboard and shaving board, they all are to be that raw material production becomes with the byproduct behind the converted timber, anxiety because of timber, its byproduct is inevitable nervous thereupon, therefore develops new timber source, and making its substitute has become the task of top priority.And North China's sunflower planting area is very wide, and its byproduct sunflower bar does not also develop so far, and the present invention utilizes its resource, produces fiberboard, replenishes society need.

In view of the foregoing, having changed traditional is raw material with timber tailing, reed, paddy and wheat stalk; Chipping machine, blower, screening machine, the technological process of production and the prescription formed in machinery equipments such as broken machine, kibbling mill, refiner, decompression diluter, transversal saws, make the hardboard that meets standard GB 1923-80 with Sunflower Stalk particle and new process formula, its major advantage is that technology is simple, with short production cycle, equipment investment is few, upward detective, raw material sources are extensively cheap, economic benefit is high.

Accompanying drawing one is a manufacturing process flow diagram of the present invention, wherein: 1. Sunflower Stalk cut material coring machine, 2. the boiling pond, 3. squeeze the stone roller machine, 4. vermicelli machine, 5. rinsing bath, 6. Rotatruder, 7. the high-order pond of applying glue moulding, 8. clap pulpboard, 9. give make-up machine, 10. hot press, 11. Sawing machines, 12. overfall liquid pools, 13. slurry recirculating pumps, 14. gelatin concentration regulating reservoirs, 15. treatment tanks.

Be the technology that raw material is made the hard fiberboard with Sunflower Stalk, comprise fiber calibration workshop section, pressing section, hot pressing workshop section and treatment and finishing section. The technology step is: 1. go core machine (1) that raw material is truncated into 10 centimeter length with cutting material earlier, clean simultaneously and remove core; 2. pack into boiling pond (2) and add running water material is flooded, directly lead to then into steam and make in the pond material boiling 25 minutes, deliver to crowded mill (3) after softening, remove part moisture content through squeezing to grind, delivering to vermicelli machine (4), material is crushed to length-width ratio is 35 fiber filaments, through rinsing pond (5) rinsing decontamination, with rotation conveyer (6) fiber filaments is sent into the high-order pond (7) of applying glue moulding; 3. stir on applying glue limit in limit in the pond, sends into to give on the make-up machine (9) again and make blank with clapping pulpboard (8), and blank thickness is 4-5 times of its finished product thickness, and bottom surface type shape is identical with finished size, and moisture content is 70%; 4. (hot pressing machine pressure is the 45-60 kilograms per centimeter to use hot pressing machine (10) hot pressing moulding², temperature is 190-210 ℃, the time is 20 minutes); 5. send into storehouse after using the whole limit of whole limit machine (11); 6. enter go back to slurry pond (12) through the slurries of clapping slurry and squeeze out, pump into gelatin concentration regulating reservoir (14) with slurry recirculating pump (13) and process usefulness next time, sewage drains into sewage disposal pond (15); 7. the weight ratio of broken Sunflower Stalk straw material and modified urea-formaldehyde resin glue is 20: 1 in the prescription, and the weight ratio of water and modified urea-formaldehyde resin glue is 30: 1.

Claims

1, a kind of is the technology that raw material is made hardboard with plant haulm, comprise fiber separation workshop section, pressing section, hot pressing workshop section and treatment and finishing section, it is characterized in that: the raw material that adopts is a sunflower stalk, processing step is: 1. with cutting material coring machine (1) raw material is truncated into 10 centimeter length earlier, cleans coring simultaneously; 2. pack into boiling pond (2) and add running water material is flooded, directly feed steam then and make in the pond material boiling 25 minutes, deliver to the stone roller machine (3) that squeezes after softening, remove part moisture content through squeezing to grind, delivering to vermicelli machine (4), material is crushed to length-width ratio is 35 fiber filaments, through rinsing bath (5) rinsing decontamination, fiber filaments is sent into the high-order pond (7) of applying glue moulding with Rotatruder (6); 3. stir on inner edge applying glue limit, pond, send into to give on the make-up machine (9) again and make blank with clapping pulpboard (8), blank thickness is 4-5 a times of its finished product thickness, and bottom surface type shape is identical with finished size, and moisture content is 70%; 4. using hot press (10), hot-forming (hot press pressure is the 45-60 kilograms per centimeter ², temperature 190-210 ℃, the time is 20 minutes); 5. send into storehouse after using trimmer (11) treating selvedge; 6. go into overfall pond (12) through the slurries of clapping slurry and squeeze out, pump into gelatin concentration regulating reservoir (14) with slurry recirculating pump (13) and handle usefulness next time, sewage drains into treatment tank (15); 7. the weight ratio of broken Sunflower Stalk straw material and modified urea-formaldehyde resin glue is 20: 1 in the prescription, and the weight ratio of water and modified urea-formaldehyde resin glue is 30: 1.
