Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Special molds are required to make seaweed biomass panels. The special mold is made of aluminum alloy, the structure is as follows figure 2 As shown, it includes a pressing plate 2, a groove body 4 and a demoulding device. The demoulding device consists of a base 5, two push rods 6 vertically fixed on the base 5 and a movable plate 3, wherein the pressing plate 2, the movable plate 3 and the concave The bottom of the tank body 4 is provided with some seepage holes 8 ( Figure 5 shown), in order to cooperate with the demoulding device, the groove body 4 is provided with through holes 7 corresponding to the positions of the two push rods 6 .

[0032] The method of using this special mold to make Ulva pore biomass plates is as follows:

[0033] (1) Raw material pretreatment: salvage Ulva ulva from ashore, wash it with tap water, and rem...

Abstract

The invention relates to a seaweed biomass plate, and provides a natural, degradable and high-strength seaweed biomass plate which is to solve the problems that the biomass plate in the prior art has low strength, and the added additives are difficult to degrade and unsafe. The seaweed biomass plate is produced by the following steps: taking seaweed as a raw material, crushing, hot-pressing and molding and drying the raw material to produce the seaweed biomass plate, wherein the main ingredients comprise seaweed plant cellulose, hemicellulose and pectin substances. The invention also provides a processing method of the seaweed biomass plate, which comprises procedures of crushing, hot-pressing molding and drying, and a special mold comprising a pressing plate with a water filtering hole and a groove body. The seaweed biomass plate provided by the invention has the characteristics of high strength, compact structure and degradation; and the plate is natural, nontoxic and safe.

Description

technical field [0001] The invention relates to a biomass board, in particular to a seaweed biomass board. Background technique [0002] Many existing packaging materials are not easy to degrade, and the disposal of these materials will not only pollute the environment, but also endanger human health. Especially in recent years, the harm caused by environmental pollution has become more and more obvious, and the society's voice for environmentally friendly packaging materials is getting higher and higher. Biomass panels are processed from natural raw materials and are easy to degrade. Moreover, the degradation products will not pollute the environment or endanger human health, so they have become the first choice of many environmentalists. Many manufacturers are also actively developing biomass panels. For example, the invention patent application with application number CN201010217190.4 provides a method for making biomass panels by extruding biomass materials; the inventi...
