Mvura inodziya yekuchembera bvunzo
Ukuru uye kureba kwechikamu chepombi chemuenzaniso chinenge 100 mm.Izvo zvikamu zvakafumurwa pamigumo miviri yechikamu chepombi inofanira kurapwa ne anticorrosion.Chikamu chepombi chinofanira kunyikwa mumvura yakanyungudutswa pa (70±2) ℃ kwemazuva makumi matatu.
Features overview editor nhepfenyuro
(1) High mechanical properties.Epoxy resin ine kubatana kwakasimba uye compact molecular chimiro, saka michina yayo yakakwira kupfuura phenolic resin uye unsaturated polyester uye mamwe epasi rose thermosetting resin.
(2) Plastic moto pombi coating uchishandisa epoxy resin, ane adhesion yakasimba.Iyo yekurapa sisitimu ye epoxy resin ine yakanyanya kushanda epoxide boka, hydroxyl boka, ether bond, amine bond, ester bond uye mamwe mapoka epolar, inopa epoxy yakaporeswa zvinhu nekunamira kwakanaka kune simbi, ceramic, girazi, kongiri, huni uye mamwe mapolar substrates. .
(3) kurapa shrinkage mwero idiki.Kazhinji 1% ~ 2%.Ndiyo imwe yemhando ine diki kurapa shrinkage mu thermosetting resin (phenolic resin i8% ~ 10%; Unsaturated polyester resin ndeye 4% ~ 6%; Silicone resin 4% ~ 8%).Linear yekuwedzera coefficient zvakare idiki kwazvo, kazhinji 6 × 10-5 / ℃.Saka vhoriyamu inoshanduka zvishoma mushure mekurapa.
(4) Tekinoroji yakanaka.Epoxy resin kurapa haaburitse kuderera kwema molecular volatiles, saka inogona kuve yakaderera kuumbwa kuumbwa kana kubata kudhiza kuumba.Inogona kushandira pamwe nemhando dzese dzekurapa mumiriri kugadzira solvent-isina, yakakwira yakasimba, poda coating uye mvura-based coating uye mamwe mapeji ane hushamwari nharaunda.
(5) Yakanakisa magetsi ekudzivirira.Epoxy resin is thermosetting resin ine yakanaka antistatic properties.
(6) Kugadzikana kwakanaka, kupikisa kwakanyanya kumakemikari.Epoxy resin isina alkali, munyu uye kumwe kusvibiswa hakusi nyore kushatisa.Chero bedzi iyo yakachengetedzwa zvakanaka (yakavharwa, isina kukanganiswa nehunyoro, kwete mukupisa kwakanyanya), nguva yayo yekuchengetedza ndeye 1 gore.Inogona zvakare kushandiswa kana ichikodzera mushure mekupera.Epoxy yakarapwa zvinhu zvine yakanakisa kugadzikana kwemakemikari.Kupokana kwayo nekuora kwealkali, asidhi, munyu uye mamwe midhiya zviri nani pane unsaturated polyester resin, phenolic resin uye imwe thermosetting resin.Naizvozvo, epoxy resin inoshandiswa zvakanyanya senge anticorrosive primer, uye nekuti epoxy resin kurapa zvinhu ndeye matatu-dimensional network chimiro, uye inokwanisa kumirisana nekumisikidzwa kwemafuta, nezvimwewo, huwandu hukuru hwekushandisa mutangi remafuta, tanker remafuta, ndege, iyo mukati memadziro emadziro etangi rese.
(7) Epoxy kurapa kupisa kuramba kazhinji 80 ~ 100 ℃.Epoxy resin inodzivirira kupisa mhando dzinogona kusvika 200 ℃ kana kupfuura.
Product zvakanakira
(1) Pombi yepurasitiki yakashongedzwa nesimbi ine simba remuchina rakakwirira, rakakodzera kushandiswa kwakaomarara;
(2) Iyo yemukati nekunze yakanamira inogona kudzivirira simbi oxidation uye ine yakanaka makemikari corrosion resistance;
(3) iyo yekupfeka ine yakasimba adhesion, yakakwirira bonding simba uye yakanaka kukanganisa kuramba;
(4) Yakaderera roughness coefficient uye friction coefficient, kupikisa kwakanyanya kune yekune dzimwe nyika kunamatira;
(5) Pombi yesimbi yakavharwa inopesana nekuchembera uye ine hupenyu hurefu hwebasa, kunyanya yakakodzera kuendesa mvura yepasi pevhu.
