Laminated Chipboard Cut To Size


         Particle board is a waste-wood product that's made by mixing sawdust with adhesives. Although it won't bow or warp like plywood, it can swell and become unstable when exposed to water. The main uses are for furniture, underlayment and as substrate for countertops. It can milled with all power tools and has moderate tear-out. Laminate and veneer finishes are the most common. Particle board comes in 4-foot-by-8-foot panels. 1/2- to 1-inch-thick precut shelving boards come in various sizes.


 The chipboard shelving made of plant fiber as the main raw material. and processed by hot grinding, sizing, paving, hot pressing and the like. The white melamine fiberboard has:density,

the density is below 450 kg/m3,called laminated chipboard cut to size,and the density is between 450-800 kg/m3. called laminated chipboard cut to size. and the density is 800 kg/ More than cubic meters called wood shelves. laminated chipboard cut to size used for the production:finished furniture.  but also for laminate flooring, door panels, partition walls, etc.

Advantages:


     The surface of the fiberboard issmooth and flat. and the material is fine, which is convenient for modeling and milling. 


     The toughness of the fiberboard is good, and it is not easy to break in the case of small thickness (such as 6MM, 3MM).


Disadvantages:


    the fiber board has poor moisture resistance. and the expansion coefficient is larger after absorbing water.


    The inside of the fiberboard is a powdery structure, and the nail holding force is poor. It is easy to loosen after the screw tightened. because the strength of the laminated chipboard cut to size is not high. the height of the furniture can not be too high, the vast majority is 2100mm.


       When the laminated chipboard cut to size produced.  Due to its internal structural characteristics. The amount of glue used is large. and the environmental protection coefficient is low to a certain extent. Solid wood finger joint Finger joint board. also known as : integrated board,laminated material,finger joint material. 


    A piece of solid wood piece that has processed by deep processing like a "finger head", . Since the raw wood strips are cross-coupled. such a combined structure has a certain bonding force. and since the surface plate is not required to  adhered up and down


MFC application


      The most popular types can used for cable reels, box making. pallet layer boards, interleaving boards, backing boards, fabric rolling boards, bedding and upholstery. Another type, known as kraft lined, can used for picture frames, pallet slip sheets. and for making boxes. One further type worth mentioning is display board. that made by gluing two to four plies together. It is popular for use as point of sale, hanging displays, showcards and dump bins.


       In its various disguises. it is the perfect material for those concerned about the future of the planet. Unlined, in particular, is 100% friendly and can be completely recycled.

 

 

types of chipboard

 

types of chipboard


Plain chipboard


      Standard  Plain chipboard made by bonding chips of wood. and adhesive together under pressure and heat until it forms a stiff board. Besides being cheap. it is also available which makes it a good option for most internal woodwork jobs. 


        This type of wood can be versatile. as it comes in three different densities: normal, medium and high-density. The normal variety is cheap and easy to work with but it is also thin and rather delicate. with chips coming away from the surface; it is often used as the back panel on cupboards and chests of drawers. 


       If necessary, it can decorated with oil-based paint as it will soak up water-based paint. The high-density version is thicker and more rigid. and ideal for use in constructing a worktop. But, getting it wet can cause irreparable damage.    


Melamine Veneered  chipboard 


       Melamine veneered chipboard is ideal to use. when constructing a worktop or bedside table. because the coating gives it some protection and enables it to  cleaned. But, where the veneer comes away from the surface. it is important to rectify this straight away as exposing the board. can leave it susceptible to damage. The melamine veneer also comes in a wide range of different colors . which will make it easier to find an option to suit your décor.     


Flooring Grade  chipboard  


       There is  Flooring Grade chipboard available on the market. that made for use on flooring and is easy to fit by the floor joists. An escape of water will result in this type of flooring soaking up the moisture like and sponge. and sections will have to removed and replaced even if water has not been in direct contact with it. but, this problem can avoided with the use of a moisture-resistant variety. which will remain strong and reduce the risk of wet rot.  


 Flame-Retardant  chipboard  


       Flame-retardant chipboard is perfect for use as part of a fire door as it treated to ensure that it does not feed a fire. but, it is also necessary for it to be rather heavy and will add to the weight of the door.  


Wood Veneered  chipboard  


       Wood veneered chipboard is beneficial. if you want the look of wood without paying for the solid variety. but, it can prove difficult to cut as it can leave a messy edge. which has to secured with masking tape beforehand to reduce the risk of the wood veneer chipping.


Plastic Veneered  chipboard 


      The surface of the board can made water-resistant with a plastic veneer chipboard. This type is available in many colors and can used for a variety of different purposes. but, if the veneer suffers damage or peels away, it will be impossible to repair. and will leave the board beneath open to damage.

 

Solid Wood Particle Board


        The so-called solid wood particle board is actually a sheet. produced by the particleboard process. and it is also considered to be a homogenized particle board.The scientific name of homogeneous particleboard  called oriented structure particle board. It made of small diameter material, thinned wood, wood core, board skin, branch. and other materials. 


      It  processed by special equipment to grow 40mm, 70mm, width 5mm, 20mm, thickness 0.3mm, 0.7. The mater of mm is a kind of wood-based panel. which  formed by hot pressing after drying, sizing and special equipment. The homogenized particleboard dried by an advanced single-channel dryer. The expansion coefficient is small and the moisture resistance is very good. 


       The flank oriented layered, so its internal internal texture is evener. than ordinary particleboard. And the powdery MDF has stronger nail holding force, bending resistance and stability. Oriented structural particle board. used as a high-grade friendly substrate by furniture manufacturers in Europe. and the United States. The domestic high-end panel furniture market has also begun to adopt. this type of plate in large areas.


Melamine face chipboard


     The melamine finish printed on the surface of the decorative paper. and then impregnated with melamine glue to form a melamine finish paper. which is then pressed onto the substrate by high temperature.it used for the surface finish of particle board and medium density board.


    Such plates, which have decorated with melamine pressure veneers. are usually called melamine plates. The surface texture is realistic, wear-resistant, scratch-resistant, and waterproof. It is suitable for production and used for panel furniture. Manufacturing.


 The melamine board has the thickness (gram weight) of the decorative paper. There imported paper and domestic paper. The surface printing ink has the distinction between imported ink and domestic ink. and the effect is also very different.


 According to the different dipping process, the three ammonia glue. and the semi-three ammonia glue divided into three parts. The wear resistance coefficient of the semi-three ammonia is not. as good as that of the whole three ammonia.


Is chipboard the same as OSB?


what is chipboard 


        Wood chips comprise the bulk of particleboard. and prepared in a mechanical chipper generally from coniferous softwoods spruce. though pine and fir and hardwoods. such as birch, are sometimes used. Particleboards may also incorporate a large proportion from recycled sources. (up to 95% plus but generally around 40%). 


      These chips are generally bound together. with synthetic resin systems such as urea- formaldehyde (UF). or melamine urea-formaldehyde (MUF). though phenol- formaldehyde (PF) and polymeric methylene di-isocyanate (PMDI). used by a few manufacturers.


      The binding system employed depends on the end use intended and the grade of the product. The most common resin employed is urea-formaldehyde. but this is only suitable for use in dry conditions. the other three resin systems confer a. measure of moisture resistance to the composite.


      Typical constituents of a particleboard are of the. order (by mass) of 83-88% wood chips, 6-8% formaldehyde based resin or 2-3% PMDI. 5-7% water, and 1-2% paraffin wax solids.


 chipboard  process


        Raw material in the form of either virgin wood. or reclaimed wood chipped, dried and graded into different sizes. Resin added to the chips and a mat formed, this would have fine chips on the surfaces with coarse chips in the centre. This mat will then be hot pressed either with what known as a multi-daylight. or daylight press which are batch presses or a continuous press. 


       The heat involved and the time in the hot press will cure the resins. so that they bind the chips together forming a board. with the desired properties (e.g. strength, density etc...). All the manufacturing processes are usually controlled by complex computer systems. that enable the operators to reproduce. the same quality with consistency and accuracy on a 24 hour basis. Once the boards conditioned and cut to size.  they will tested to prove compliance with the relevant specification and claims.


        In the UK all the particleboard mills use their own process. derived wood fuels to generate process heat. This means. that as much as 55% of the heat need for production is currently derived from renewable sources.


 chipboard  usages


       The special properties of particleboard have several advantages. in a wide range of construction and furniture applications. Thus, its good mechanical performance. which is the same along and across the panel, and its availability in large sizes renders. it appropriate for use as floor decking, either on timber joists, or as a floating floor system. 

 

      Different grades of the product. are available for different environmental conditions and different levels of loading. ranging from domestic to industrial usage including both platform and raised access floors. The higher grades also find widespread use in industrial storage systems. Guidance on the use of load-bearing grades of particleboard in floors. walls and roofs given in DD CEN/TS 12872.


     Large quantities of particleboard. are also used in the manufacture of kitchen units and worktops. and in dining-room and bedroom units.  these generally have a veneered or laminated finish.


       Particleboard is commonly used in furniture and worktops. (Grades P1, P2, P3) and structural flooring (Grades P4, P5, P6 & P7).


What is osb?


         OSB is an engineered wood product that's made with flakes or large chips of wood. The panels formed from layers glued. together with their strands at 90-degree angles to one another. The cross orientation of the layers adds strength to the panels. and makes OSB well-suited for use as a structure board in sheathing and underlayment. 


       It can cut with all power saws, but since it's a structure board, it's not suited to shaping. sanding or other milling operations. Paints and primers will adhere to OSB. but the main usage is as an underlayment that shouldn't need finishing. OSB panels are 4-foot-by-8-foot, 1/4- to 3/4-inch thick and also available in tongue and groove panels.


       The timbers used in OSB manufacture. include both softwoods (spruce, pine) and hardwood (aspen). Wood strands cut from debarked logs which held against rotating knives. The ribbon of flakes produced is usually about 75mm wide. and this breaks up on handling to produce individual flakes. which are 75mm along the grain and from 5 to 50mm across the grain.


osb process


     After drying, these flakes are generally. sprayed with a synthetic resin, though one or two mills use powdered resins. One of the important points in OSB manufacture is the removal. of fines before resin application. this results in the use of lower amounts of resin in OSB (2-3%) compared with other resin bonded panel products.


      The three main adhesives used in the production of OSB are phenol formaldehyde (PF). Isocyanates (MDI or PMDI) and melamine urea formaldehyde (MUF). These are either used on their own or the core and the surface layers may use two different types of adhesive.


      All these resins confer a measure of moisture resistance to the composite.


       In the formation of the mat the strands aligned either in each of the three layers of the panel. or, more , in only the outer two layers. The degree of orientation varies within any one panel. and also in panels from different manufacturers. thus, in panels from different manufacturers. it is possible to get ratios of property levels in the machine- to cross-direction of 1.25:1 to 2.5:1. thereby emulating the ratios found in plywood.


    The boards pressed with heat to cure the adhesive. and compress the strands to form a compact and dense product to the desired thickness.


      There may be a sanding process following pressing. and so it is possible to get sanded boards as well as un-sanded versions.


osb usage


        Because of its lay-up and composition. OSB is a panel for construction and used for flooring. flat roof decking and wall sheathing but used in furniture where it is not seen. Different grades of the product. are available for different levels of loading and different environmental conditions. Guidance on the use of OSB in these load-bearing applications given in DD CEN/TS 12872. Generally, for the same loading conditions. a thinner board of OSB can used than a load-bearing particleboard.


      There are currently “deemed to meet” tables for domestic floor. and roof applications in BS 8103-3 (Code of practice for timber floors and roofs for housing). for plywood and particleboard. butthere is no deemed to meetroute for non-domestic floor applications at present.


       Large quantities of OSB are also used for sarking. and industrial packaging and in the construction of site hoardings and pallet tops.
