Hot solid sex enhances plastic corrosion resistance to be able to experiment domestic and international standard basically has JIS K 7114 of standard of ASTM C581 of standard of ISO 175 of standard of standard GB/T 3857, international, United States, Japan to wait. The article is main to GB/T 3857, ISO 175, ASTM C581 3 standards undertake contrast. Specific and comparative content sees a table 1.
3 experiments standard does not have GB/T 3857 of contrast of content of standard of watch 1 GB/T 3857, ISO 175, ASTM C581, ISO 175, ASTM C581 give out sample is anticorrosive judge basis, set only how go designing and carry out anti-corrosive soaking tests plan, sample is anti-corrosive by experimental architect basis experience write one's own ticket (with foregone but anticorrosive sample contrasts below coequal condition judge) . For better service at us anti-corrosive experiment, referenced and relevant document, the article offers be able to bear or endure below chemistry corrodes judge standard (see a table 2) for reference:
Express 2 judge to heat up solid sex to enhance plastic corrosion resistance can grade level notes 1: Exterior circumstance includes exterior burnish change, color change, apparent bate or sclerosis, crazing or crackle, statified, fiber to appear, dissolve bilges wait for a phenomenon. What above offers is anti-corrosive judge is not absolutely, sample is able to bear or endure not anti-corrosive, corresponding material can be used, the actual application situation that needs the person that the basis is used sometimes will decide. Data bears not anti-corrosive actually need has a premise: Material uses how many time below how many temperature. Had this premise, ability is able to bear or endure to material not anti-corrosive, can use make decide well and truly. Instron is had before Hua Changju combines the mental view in content research and development machine of all-purpose material experiment 1 (contain chamber of lukewarm environment of discretion of form a complete set - 60—300 ℃ ) , machine of experiment of MTS all-purpose material 2, stage of DMA 1 of analyzer of TA dynamic machinery, TA difference shows scanning to measure stage of hot appearance DSC 1, waters and Agilent gel permeate GPC of color atlas appearance each 1, thermoFisher Fourier commutation is infra-red stage of spectrometer FT-IR 1, MTS heat is out of shape temperature experiments machine 1, MTS places hammer to pound experiment machine 1, anton-Paar flows change appearance 1, still have the electric function such as test meter of puncture of resistor instrument, dielectric constant instrument, voltage to check an instrument, reach cone-shaped quantity to heat up the burning behavior such as appearance of index of appearance, perpendicular combustion appearance, oxygen to check an instrument. We still will have investment of machine of experiment of 2 Instron exhaustion to use 2022. We can undertake to liquid colophony active of molecular quantity, structure, reaction, technical properties undertakes detecting assessment, the requirement that can wait for a standard according to GB, ISO, ASTM reachs its composite material to colophony mould body (Bo fine, carbon fine and other enhance material to wait for colophony radical composite material) mechanical function, heat-resisting function, report function, corrosion resistance can wait undertake detecting. It is the picture of partial instrument equipment below:
China prosperous polymer is dedicated high quality colophony 64 years of authors: Arry composing: Brand of green tree nation walks along the road of innovation to contact our company name: Huadongli is versed in company of of limited company of polymer of university China prosperous: Shanghai dragon Wu Lu 4600 11 date buildings, postcode: 200241 factory: Hua Lu of order of district of Shanghai chemical industry phone of 130 postcodes 201507: 86-21-64253377 turns; Or factory 67120007 turn mailbox: Huachang @hchp.com.cn
