3 mechanical means
The door handle of train carriage, the brake ring of lorry etc. can be made of nylon 66.Other also can be used nylon 66 as the turbine on insulating washer, apron block, boats and ships, screwshaft, spiral propeller, sliding surface bearing etc. and make.High impact properties nylon 66 also can be made pipe wrench, mould of plastics, wireless control vehicle body etc.Do not strengthen grade nylon 66 and be generally used for manufacturing low creep, free from corrosion nut, bolt, screw, nozzle etc.; Strengthen grade nylon 66 for the production of the fixing climbers etc. of chain, travelling belt, flabellum, impeller and scaffolding.
4. other industry
Utilize the resistance to creep properties of nylon 66 and solvent resistance, can manufacture a series of daily necessities, as the gas lighter being injection molded into non-toughness reinforcing nylon 66 and aerosol nozzle, Sunglasses lenses sun clips, comb, button etc.Toughness reinforcing nylon 66 is for the manufacture of skating boots, ski part, tennis racket line cover, windsurfing junctor etc.Glass strengthens Toughed nylon66 for the production of bicycle quick, handle of a knife and gun stock.
In furniture industry, also often adopt web member that nylon 66 manufactures, ornament, drawer pulley, slide rail etc.In addition, a large amount of article and implements is also directly manufactured with nylon 66, and as gear, flabellum, sewing machine cam, laundry under-chassis, some take the machinery that gasoline is power, as mower.In military affairs, sheath, confidential paper cover and gunpowder band etc.
In construction industry, nylon 66 is for making escalator railing, automatically-controlled door horizontal bar, window frame, door guide roller etc.
In packing business, nylon 66 can be for making the container etc. of film and multilayer film, bake.Nylon 66 thin-films Oxygen vapor permeabilities are little, have the function that prevents content deterioration by oxidation, and oil-proofness, low-temperature impact resistance are good, can be used for the packing of the food such as meat, ham, shrimp, and future develop is good.
Therefore, for plastics, how to improve flame retardant resistance and become a problem in the urgent need to address.
