Abstract
The present invention is a building material, is to be the production technology that main raw material is made fiberboard with the Sunflower Stalk, and its product is used to make furniture and builds house partition wall etc.The present invention is for replenishing the needs of market to timber, enlarge the source of raw material of artifical plate, adopt the local Sunflower Stalk of abounding with to do raw material, change the technology and the hardboard that meets standard GB 1923-80 made of prescription of traditional manufacturing fiberboard, its major advantage is that technology is simple, with short production cycle, equipment investment is few, go up detective, raw material sources extensively and cheap, economic benefit is high.
Description
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 on the market some wood-based plates are arranged also now, as fiberboard and shaving board, they all are to be that raw material production becomes with the byproduct behind the converted timber, and because of the anxiety of timber, its byproduct is inevitable nervous thereupon.Therefore develop new timber source, 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.The present invention utilizes its resource, produces fiberboard, replenishes society need.
In view of the foregoing, we consider to change the technology of traditional manufacturing fiberboard, and raw material and prescription, replace byproduct behind the converted timber with sunflower bar particle, adopt new technology and fill a prescription and make the hardboard that meets standard GB 1923-80, its major advantage is that technology is simple, with short production cycle, equipment investment is few, last detective, raw material sources are extensively cheap, the economic benefit height.
Raw material of the present invention, prescription and technology is following provides.
Raw material: sunflower bar, modified urea-formaldehyde resin glue.
Prescription: the weight ratio of broken sunflower bar straw material and modified urea-formaldehyde resin glue is 20: 1; The weight ratio of water and modified urea-formaldehyde resin glue is 30: 1.
Its manufacturing technique is: as shown in drawings: 1, the sunflower bar cuts that material removes stamen machine, 2, boiling pond, 3, squeezes stone roller machine, 4, vermicelli machine, 5, rinsing bath, 6, Rotatruder, 7, the high-order pond, 8 of applying glue moulding, claps pulpboard, 9, gives make-up machine, 10, hot press, 11, Sawing machine, 12, overfall liquid pool, 13, slurry recirculating pump, 14, gelatin concentration regulating reservoir, 15, treatment tank.
It is long by about 10 centimetres sunflower bar material to cut material coring machine 1 with the sunflower bar, cleans coring simultaneously; The boiling pond 2 of packing into, and add running water and material is flooded be advisable, directly feed steam then and make 25 minutes softening stone roller machines 3 that squeeze of delivering to of material boiling in the pond, remove moisture through squeezing to grind, deliver to the fiber filaments that vermicelli machine 4 is crushed to material length-width ratio about 35, fiber filaments after rinsing are sent into Rotatruder 6 through rinsing bath 5 rinsing decontaminations and to be revolved the high-order pond 7 of gum forming, stir back giving on the make-up machine 9 on inner edge applying glue limit, pond and make blank with clapping pulpboard 8, blank thickness is 4-5 a times of finished product thickness, the identical moisture content with finished size of size is 70%, through hot press 10 hot-forming (its hot press pressure be the 45-60 kilogram/(centimetre)
2, temperature is 190 ℃-210 ℃, the time is 20 minutes), with sending into storehouse behind trimmer 11 treating selvedges.Go into overfall liquid pool 12 usefulness slurry recirculating pumps 13 through the slurries of clapping slurry and squeeze out and pump into gelatin concentration regulating reservoir 14 for handling usefulness next time.Sewage drains into treatment tank 15.Infeed sunflower bar, B confession steam, C for running water, D confession glue by A.
