【Concept】 As the name suggests , the use of synthetic organic materials of acrylic bathtubs
======================== 【Material term】 Acrylic material surface acid methyl ester is polyethylene , the back is made of resin and glass fiber gypsum to enhance the carrying capacity . The official name is the glass fiber reinforced plastic tub ( acrylic ACRYLIC English homonym ) . That "glass ." The surface layer material is methyl propionate , methyl reverse covered with glass fiber , coated with special resin reinforcement . Whole tub should uniform color, smooth surface, no delamination, bubbles . The surface layer thickness is generally 3 mm or more , and the combination of solid and glass fiber , no peeling . The thickness is generally 3 ~ 10mm. ======================== 【Advantages Terminology】 Cost is cheaper , good insulation effect , the water temperature can be maintained for a long time , the contact surface is no cold feeling , feel the warm , rich and varied shapes , rich color variations , light weight , good finish, easy molding , cooling is slow, easy to scrub clean , Easy to install ======================== 【Term Disadvantages】 Surface is easy to get to spend hard objects , poor temperature , pressure ability, do not wear, surface easy to aging, easy to hang dirty, after some time , the surface was easily noticeable gray. Therefore, the use of more than three years in acrylic bathtub bathtub very little discoloration of the surface .
However, some brands in the production using imported high brightness, high hardness dedicated sanitary acrylic sheet , to some extent, overcome some of the disadvantages of acrylic . ======================== 【Process term】 ------------------
1 [ molding ] Bath, shower chassis, backplanes and other sanitary ware usually chocolate molding plastics or composite board panels plastic molding , since the appearance of more complex products such as bath with deep molding height, materials and machinery used in ordinary packaging materials process requirements are difficult to meet , so the appropriate choice of plates and the appropriate choice of equipment is an excellent base molding ware . ------------------ 2 [ Plate ] Molding plastic ware mainly used pure acrylic plate ( chemical name methyl methacrylate ) A BS information or composite materials , thermoplastic materials , and recently a new development. Special sanitary acrylic plate used has an excellent appearance due to the smoothness , abrasion resistance equivalent to aluminum , easy to rub hair , easy cleaning, and if an accident occurs abrasion appearance , as long as polishing agent, recovery can be quickly and easily trimmed . ------------------ 3 [ die ] Actual production molding press ware design drawings or samples , plastic mold design and processing . Plastic mold is generally made ??of aluminum alloy or resin mold , aluminum mold long life, good processing characteristics , appearance finish, but because of the higher cost, longer processing cycle , practices ware production application subject to certain restrictions . Resin mold due to lower cost, short processing cycle , the current rapid changes in the domestic ware varieties environmental applications more widely. ------------------ 4 [ vacuum forming ] The well plate according to claim cut acrylic sheet is heated and softened in a furnace in general plastic molding machine at a temperature 180-220 ° plate , composite boards are generally 140-190 ° ) after softening by mechanical pressing in the mold , mold under sealed conditions , by blowing compressed air or vacuum suction up , plate heat tensile deformation , adsorbed on the walls of the mold , depending on the timing of the cooling fan started to make sheet metal forming harden , and then release , the product removed. Depending on the shape of the product and the use of different models , the process is slightly different . Advanced molding technology using digital automatic molding and send products , artificial soil is a step by step way to do it . With China and the large-scale industrialization and modernization of the labor restructuring , indigenous methods to be phased out , the investor must consider this reality . ------------------ 5 [ dressing stick ] After forming the billet, to apply sticky resin to strengthen the so-called bottom is generally deposited stick with unsaturated resin and glass fiber composite materials in Ware embryo , the molded product has sufficient strength. Mechanical methods are generally deposited stick spray and hand applicator two kinds . Machine gun spraying is the use of special resin and fiberglass truncated to spray along the bottom surface of the ware , and then use a robot or manual pressure rollers flatten the current ware production mostly by mechanical applicator way more. After completion of dressing stick , best placed in a curing oven thermostat 4050 ℃ environment - drying room fully cured , cured in the future after the thermostat deformation products decreased significantly. ------------------ 6 [ cutting edge ] After the deposition sticky after cured products , began cutting edge cutting , hand-cut labor- consuming, difficult to ensure the quality and security risks seriously . Using mechanical cutting edge to solve the above problems, the vast majority of manufacturers are now using special cutting edge machine operation. ------------------ 7 [ Punch ] Punch on bath ware , etc. If on a plane , you should try to use the machinery for processing, such as porous drilling. Devices , such as the side of the nozzle holes , the choice of machining centers or manipulator ( industrial robots ) for processing, but the equipment is more expensive , currently mostly used manually. ------------------ 8 [ grinding ] Ware hole on the device to prevent leakage should be grinding, sharpening the use of dedicated head ware sticky layer deposited on the back of a ring -type device grind flat , more conducive to leakage protection accessories installed , this process can not be ignored . ------------------ 9 [ brackets ] Ware stents wood , plastic , steel and other materials , including stainless steel square tube production more . When dressing stick to the mounting bracket with a pad or frame fixed in place on the product , and then screw or clip method of the bracket is installed, bad sanitary bracket , the impact to the user's safety. Thus , the bracket must be done ware strong and stable . ------------------ 10. [ Assembly ] Water fittings, electrical devices should pay attention to water , to ensure peace. Production should be considered in a larger assembly line operations . In general , assembly bath is recommended to use a desktop without extrusion production line conveyor , shower assembly recommends using a dedicated assembly lines, shower screen assembly using the hanging assembly lines. The mounting assembly using the lift station Jacuzzi will significantly improve assembly efficiency ======================== 【Reserved Integrate / Just Reference】 【Translation is by The Network】 |
