Finir-finir to glue plywood to be able to use a wide range of adhesives, for example:<\/span>
\n a) Based on the origin of the material, divided into:<\/span>
\n o Adhesive vegetable, such as soybeans, peanuts, cassava (tapioca)<\/span>
\n o Adhesives animal, eg casein (milk), fibrin, a protein, bone \u00d8 Adhesives synthesis, for example, urea formaldehyde, phenol formaldehyde, melamine formaldehyde, resorcinol formaldehyde<\/span><\/p>\n

b) Based on the resistance to water and weather influences outside differentiated by:<\/span>
\n o Adhesives WBP, the adhesive is resistant to outdoor weather, water, and air humidity around.<\/span> These types of adhesives for example fenoll formaldehyde, and plywood produced with this adhesive called exterior plywood (type 1).<\/span> If highly resistant to humidity around the adhesive force of 5-15 kg \/ cm2.<\/span>
\n o Adhesives MR, the adhesive does not withstand the humidity in the room.<\/span> Examples of these types of adhesives for example, urea formaldehyde, and plywood which produces so-called interior plywood (type II).<\/span> When tested strength of less than 5 kg \/ cm2.<\/span><\/p>\n

c) By way of hardening:<\/span>
\n o The glue that hardens in the heat, for example blood adhesives, fibrin (animal), adhesive synthesis.<\/span>
\n o The glue that hardens in the cold, for example, bone adhesives, plant.<\/span> > The glue that hardens due to a chemical reaction eg casein (milk), adhesive synthesis.<\/span>
\n o The glue that hardens due to evaporation of the solvent: adhesives are insoluble in water.<\/span><\/p>\n

d) Based on the recovery capabilities:<\/span>
\n o Perekatthermoplastic, can be restored and rebuilt<\/span>
\n o thermosetting adhesive, it can not be restored<\/span><\/p>\n

When will be used to glue in the manufacture of plywood finir the types of adhesive should be added again with some other materials, among others:<\/span>
\n Hardener (hardener), for example NH4Cl (about 1%)<\/span>
\n Extender (developer), for example, wood flour, coconut shell flour, starch kaolin (about 6%)<\/span>
\n Water (as a viscosity regulator, to taste)<\/span><\/p>\n

Each mix adhesive with a viscosity (poise) has a lifetime of certain specified that need to be considered in the preparation and use.<\/span> The amount of adhesive dilaburkan (GPU) per unit area of \u200b\u200bsheet plywood panels made is determined by the formula:<\/span>
\n GPU = Gram Pick Up (kg \/ m2 \/ cm2)<\/span>
\n S = $ MSGL \/ $ MDGL usually 20-50<\/span>
\n A = area of \u200b\u200bthe panel (m2, cm2)<\/span><\/p>\n

An explanation of S can be given as follows.<\/span>
\n $ MSGL = million square glue line, namely resurfacing adhesive system with one line of adhesive.<\/span>
\n $ MDGL = million square double glue line, the adhesive resurfacing system with two lines of adhesive<\/span>
\n<\/a><\/p>\n

Adhesives which dilaburkan (GPU) $ MDGL = $ MSGL + 10%<\/span>
\n o If the plywood is composed of 3 layers finir, then resurfacing is done with the system $ MSGL on both surfaces of the core finir<\/span>
\n o If the plywood layer 5, the adhesive is given a second surface of each cross-band (there are two cross-band).<\/span> Cross band is finir number 2 of the top-bottom directly below the face and back veneer.<\/span>
\n o If the 7-layer plywood is given a second adhesive surface of the 2 CB and the two surfaces of the center core of its veneer.<\/span> Center finir the core is located at the middle of the middle of the inside of the plywood composition.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
