Nzira yekubatanidza pombi yemoto: shinda, goko, flange, nezvimwewo. Pombi yesimbi yemukati neyekunze ye epoxy composite yekudzivirira moto ihupfu hwe epoxy resin hwakagadziriswa hune simba guru hunodzivirira ngura, hune simba rakanaka rekudzivirira ngura yemakemikari. Inogadzirisa matambudziko akawanda akadai sekuora kwengura pamusoro uye kukura kwemadziro emukati mezvigadzirwa zvakafanana mushure mekushandiswa kwenguva refu, kuitira kudzivirira kuvharika kwemukati kunokanganisa kushandiswa, kuitira kuti ivandudze hupenyu hwepombi dzekudzivirira moto dzakakosha. Nekuda kwekuwedzera kwezvinhu zvinodzora moto muzvinhu zvekuputira, kuramba kwekupisa kwechigadzirwa kunovandudzwa zvichienzaniswa nezvimwe zvigadzirwa zvakafanana. Naizvozvo, hazvizokanganisi kushandiswa kana tembiricha yemhepo yakakwira zvakanyanya. Hupenyu hwebasa uye mashandiro emapombi emoto akafukidzwa mukati nekunze zviri nani kupfuura emapaipi egalvanized. Ruvara rwacho rutsvuku.

Fekitori yedu inonyanya kugadzira mapaipi emoto, mapaipi esimbi akagadzika, mapaipi ekugadzira hupfu, mapaipi ekugadzira hupfu uye mapaipi esimbi ane 6-inch. Mashandisirwo: mvura yemoto, gasi uye masisitimu ekufambisa mapaipi ane furo. Hunhu hwechigadzirwa hunopfuura nemitero yemutero uye hunopfuura miedzo yakawanda usati wabuda mufekitori. Tevedzera mwero wehunhu hwenyika nedzepasi rose.

(1) Hunhu hwepamusoro hwemakanika. Epoxy resin ine kubatana kwakasimba uye chimiro chakakora chemamorekuru, saka hunhu hwayo hwemakanika hwakakwira kupfuura maresini e thermosetting akadai se phenolic resin uye unsaturated polyester.

(2) Kuputirwa kwepombi yemoto yakafukidzwa nepurasitiki kunoshandisa epoxy resin, ine kunamatira kwakasimba. Sisitimu yekuporesa epoxy resin ine epoxy group, hydroxyl group, ether bond, amine bond, ester bond nedzimwe polar groups dzine basa guru, izvo zvinoita kuti zvigadzirwa zve epoxy cured zvibatanidzwe zvakanaka kusimbi, ceramics, girazi, kongiri, huni nedzimwe polar substrates.

(3) Kudzikira kudiki kwekupisa. Kazhinji 1% ~ 2%. Ndiyo imwe yemhando dzine kudzikira kudiki kwekupisa pakati pemaresini ethermosetting (phenolic resin i8% ~ 10%; unsaturated polyester resin i4% ~ 6%; silicone resin i4% ~ 8%). Coefficient yekuwedzera yakatsetseka idikiwo, kazhinji 6 × 10-5/℃. Saka, vhoriyamu haishanduki zvakanyanya mushure mekudzikira.

(4) Kugadzirwa kwakanaka. Epoxy resin haiburitse mamorekuru mashoma panguva yekupisa, saka inogona kugadzirwa pasi pekumanikidzwa kwakaderera kana kumanikidzwa kwakabatana. Inogona kushanda pamwe chete nezvimwe zvinhu zvinodzivirira zvakatipoteredza kugadzira machira anochengetedza nharaunda akadai semachira asina solvent, machira akasimba, machira eupfu uye machira anobva mumvura.

(5) Kudzivirira kwemagetsi kwakanaka kwazvo. Epoxy resin iresini inogadzirisa thermosetting ine hunhu hwakanaka hwekusagadzikana.

(6) Kugadzikana kwakanaka uye kuramba makemikari zvakanaka. Epoxy resin isina alkali, munyu nezvimwe tsvina hazvisi nyore kuora. Chero bedzi yakachengetwa zvakanaka (yakavharwa, isina hunyoro uye tembiricha yepamusoro), nguva yekuichengeta igore rimwe. Mushure mezuva rekupera, kana kuongororwa kwacho kwakakodzera, inogona kushandiswa. Epoxy curing compound ine kugadzikana kwakanaka kwemakemikari. Kudzivirira kwayo ngura kune alkali, acid, munyu nezvimwe zviri nani pane iyo ye unsaturated polyester resin, phenolic resin uye mamwe ma thermosetting resins. Saka, epoxy resin inoshandiswa zvakanyanya se anti-corrosion primer. Nekuti epoxy resin yakagadziriswa ine chimiro che network chetatu-dimensional uye inogona kuramba kuisirwa kwemafuta, inoshandiswa zvakanyanya mumadziro emukati ematangi emafuta, matangi emafuta uye ndege.

(7) Kudzivirira kupisa kwe epoxy curing compound kunowanzova 80 ~ 100 ℃. Mhando dze epoxy resin dzisingapisi dzinogona kusvika 200 ℃ kana kupfuura.
