Description
Technical field
The application belongs to plastic material field, relates in particular to the wear-resisting switch of a kind of polyformaldehyde resin.
Background technology
Derlin is strong and hard well allusion quotation has thermoplastic (property) plastics of good fatigability and chi ten stability, its electricity has low frictional coefficient and good thermotolerance to think that Derlin is similar to nylon, but its resistance to fatigue, creep resistant, hardness and water tolerance are better than nylon.Zhang is that the creep resisting ability of Derlin is not so good as polycarbonate.As previously mentioned, Derlin has excellent resistance to molten chaste tree property, does not also find the organic solvent that can dissolve Derlin with F at 70 ℃ at present; But it can be in some solvent swelling.The acid of Derlin chicken roost, alkali and oxygenant are responsive.Although c-O key is polarity. it is balanced. and polarity is more much smaller than the carbonyl in nylon, and its result causes Derlin to have relatively low water absorbability.A small amount of moisture of absorption may cause swelling and chi dimensional change, but can not cause polymkeric substance hydrolysis and degrade.The impact of moisture is more much smaller than nylon polymer.Ultraviolet raised path between farm fields can be able to cause poly-platform thing degraded, can be by adding carbon black to reduce this degraded.Multipolymer has and the similar character of homopolymer conventionally, but the mechanical property of homopolymer is slightly higher than multipolymer. and its fusing point is also higher, but its thermostability and alkali resistance are poorer than multipolymer.Derlin and the blend of poly-krypton ester elastomer improve its toughness, and these materials can have been bought on market.
Polyoxymethylene is a kind of smooth surface, and glossiness hard and fine and close material is yellowish or white, can be at life-time service in-40-100 ° C temperature range.Its wear resistance and self lubricity are also superior than most engineering plastics, have again good oil resistant, resistance to superoxide performance.Very not acidproof, not resistance to highly basic and the not radiation of resistance to solar ultraviolet; The tensile strength of polyoxymethylene reaches 70MPa, and water-absorbent is little, and dimensional stabilizing is glossy, and these performances are all good than nylon, and the resin that polyoxymethylene is highly crystalline is the most tough and tensile in thermoplastic resin.Tool heat resistanceheat resistant intensity, flexural strength, resistance to fatigue intensity is all high, wear resistance and electrical property are good, development along with social city, technicalization, hommization, design that a kind of frictional coefficient is low, polishing scratch width is little, the high polyformaldehyde resin switch fabric of compressive strength, to meet the need of market, is very important.
