Commoness conveyor V Belt use elastic in assorted apparatus awning cover, beanbag gum, elastic bolt clean glue, bolt layers stick glue.
When application the actual impact, chafe and microbial corrosion, as able-bodied as a array of aging. Therefore, appeal awning elastic has acceptable compactness backbone (18 mpa or greater) and chafe attrition (abrasion abundance 0.8 cm3/1.61 Km or less), ageing resistance, attrition to erosion. In accession to requirements with acceptable action backdrop such as viscosity, blueprint is as follows: net gum elastic technology is accustomed antecedence to with accustomed elastic or with just the adapted bulk of styrene butadiene rubber, adhering agreeable ascendancy in 50% ~ 55%. Nitrile butadiene elastic (NBR with acceptable automated properties, mineral oil, hot water, blast resistance, a, b, c, butane - 40 ~ 120 for O ring and oil allowance cup accepted from accepted hydraulic barrage arrangement for changeless allowance or activating seal. In accustomed elastic formula, the dosage of sulfur 2.5 superior around; In styrene-butadiene elastic formula, the superior of sulfur bulk was 1.5 ~ 2.0. Accelerator M, DM, and frequently used, accelerator CZ, accelerator NOBS, etc afterwards aftereffect sex is acceptable for absolute elastic styrene-butadiene rubber. Reinforcing conveyor can accept top wear-resistant carbon black, Chinese cool wear-resisting carbon black, etc., dosage of 40 ~ 50 superior copies. Softeners generally accept the varieties of oil, abundant oil, ache tar and petroleum resin, coumarone resin. 2, absorber rubber
Cushion elastic amid the adhering and the bulk layer, can access the bonding strength, and can blot and banish the appulse of the conveyed material, a absorber role. Elastic has acceptable adhesiveness (the adherence of elastic and bolt acuity 3.15 N/mm), acceptable elasticity, beneath calefaction assembly and calefaction dissipation, action achievement is good. Frequently acclimated elastic and butadiene elastic and accustomed rubber, elastic agreeable is 50% ~ 55%. With adapted use of low sulfur vulcanization system, in adjustment to advance the adherence amid elastic and bolt layer. Accelerator M, DM, TMTD and system. Semi reinforcing carbon atramentous and carbon atramentous acclimated top wear-resisting, dosage shoulds not be too much, generally about 10 superior copy. Softener to accept acceptable varieties access viscosity, such as ache tar, solid coumarone, etc. Increases and the bulk of petroleum resin, coumarone adhering can abate contrarily bolt band adhesion.
Conveyor belt appearance of several kinds of adhering acclimated in:
Nitrile butadiene elastic (NBR with acceptable automated properties, mineral oil, hot water, blast resistance, a, b, c, butane - 40 ~ 120 for O ring and oil allowance cup accepted from accepted hydraulic barrage arrangement for changeless allowance or activating seal.
Ternary 3-20 EPDM with top temperature, aggressive to steam, anemic acid, does not accommodate mineral oil, anchor oil - 40 ~ 160 acclimated for top temperature gas allowance can ability (200 degrees)
Fluorine elastic (FKM heat, acerbic and acrid resistance, attrition to chemicals, all kinds of mineral oil, banishment resistant, anti-aging - 40 ~ 220 frequently acclimated in adverse environment, such as metallurgical industry, all-embracing engineering accouterment changeless seal.
Polyurethane TPU is a non-toxic, oil resistant, aggressive to hydrolysis top wear-resisting material. - 40 ~ 100 is acclimated in the oil butt shaft and aperture with GY blazon sealing ring and FS and dusty, etc.
POM POM oil resistance, acceptable abrasion resistance, top compressive strength, appulse aggressive achievement is good, accept acceptable self-lubrication, admeasurement stability. - 30 ~ 140 assembly aggressive blooper ring, ring, ring, etc
Ptfe PTEF acceptable actinic stability, top and low temperature attrition and assorted medium, low abrasion coefficient, self-lubrication. - 260 ~ 260 frequently acclimated on automated allowance materials, assembly abrasion ring and adviser ring and acclimated in metallurgical, chemical, engineering machinery, etc.
Nylon MC nylon 1010, nylon 66 oil blazon casting nylon actinic achievement and automated achievement is good, can alter allotment of metal automated products. - 10-200 acclimated in machinery, petroleum, chemical, textile, press and dyeing, cardboard making, adamant and animate industry.
Silicone elastic MVQ calefaction resistance, algid resistance, baby compression, deformation, but the low automated strength. - 60-230 is acceptable for the top and low temperature is not top acceleration alternating allowance and all kinds of aliment machinery.
PPS a high-performance engineering plastics PPS, acceptable insulation and top backbone - 40 ~ 260 acclimated in oil, oil able-bodied measuring, top ability cyberbanking insulation parts.
