Uburyo bwo guhuza umuyoboro w'umuriro: umugozi, umuyoboro, flange, nibindi. Umuyoboro w'icyuma uhuza imbere n'inyuma wa epoxy wo kurinda inkongi ni ifu ya epoxy resin ivuguruye kandi ikomeye irwanya ingese, ifite ubushobozi bwo kurwanya ingese mu buryo bwiza. Ikemura ibibazo byinshi nko kwangirika kw'ingufu zo hejuru no gupima imbere ku nkuta z'ibicuruzwa bisa nyuma yo gukoreshwa igihe kirekire, kugira ngo hirindwe ko imbere hashobora kugira ingaruka ku ikoreshwa, bityo binoze cyane igihe cyo gukora imiyoboro yihariye yo kurwanya inkongi. Bitewe no kongeramo ibikoresho bigabanya inkongi mu bikoresho byo gusiga, ubushyuhe bw'ibicuruzwa burushaho kwiyongera ugereranije n'ibindi bikoresho bisa. Kubwibyo, ntibizagira ingaruka ku ikoreshwa iyo ubushyuhe bw'ikirere buzamutse cyane. Igihe cyo gukora n'imikorere y'imiyoboro y'umuriro imbere n'inyuma ni byiza cyane kuruta iby'imiyoboro ya galvanised. Ibara ni umutuku.

Uruganda rwacu rwihariye mu gukora imiyoboro y'umuriro, imiyoboro y'icyuma gikozwe mu cyuma cya galvanised, imiyoboro ikoze mu ifu, imiyoboro ikoze mu ifu n'imiyoboro y'icyuma ya santimetero 6. Imikoreshereze: amazi akoreshwa mu muriro, itangwa rya gaze n'imiyoboro ikoze mu ifu. Ubuziranenge bw'ibicuruzwa bunyura muri gasutamo kandi bugatsinda ibizamini byinshi mbere yo kuva mu ruganda. Hubahirije amahame y'ubuziranenge y'igihugu n'ay'amahanga.

(1) Imiterere ikomeye ya mekanike. Resine ya epoxy ifite imiterere ikomeye ya molekile n'imiterere y'uturemangingo twinshi, bityo imiterere yayo ya mekanike iri hejuru ugereranyije na resine zisanzwe za thermosetting nka resine ya phenolic na polyester idafite amazi.

(2) Irangi ry'umuyoboro w'umuriro upfutse muri pulasitiki rikoresha epoxy resin, ifite ubushobozi bwo gufatana neza. Sisitemu yo gucukura epoxy resin irimo epoxy group, hydroxyl group, ether bond, amine bond, ester bond n'andi matsinda y'imibumbe ifite imikorere myiza, ituma ibicuruzwa bya epoxy resin bifatana neza n'ibyuma, ibumba, ikirahure, sima, imbaho ​​n'ibindi bice by'imibumbe.

(3) Gushonga guto. Muri rusange 1% ~ 2%. Ni imwe mu moko afite gushonga guto cyane muri resins za thermosetting (resins ya phenolic ni 8% ~ 10%; resins ya polyester idafite amazi ni 4% ~ 6%; resins ya silicone ni 4% ~ 8%). Coefficient ya linear expansion nayo ni nto cyane, muri rusange ni 6 × 10-5/℃. Kubwibyo, ingano ihinduka gato nyuma yo gushonga.

(4) Ubuhanga bwiza. Resine ya epoxy ntabwo ikora ibintu bihindagurika cyane mu gihe cyo gushonga, bityo ishobora gukorwa munsi y'umuvuduko muke cyangwa igitutu cyakozweho. Ishobora gukorana n'ibintu bitandukanye bivura kugira ngo ikore ibintu bikingira ibidukikije nk'ibidafite ibirungo, ibirungo bikomeye, ifu n'ibirungo bishingiye ku mazi.

(5) Gukingira neza amashanyarazi. Resin ya epoxy ni resin ikoresha thermosetting ifite ubushobozi bwiza bwo kurwanya static.

(6) Ituze neza kandi irwanya imiti. Resine ya epoxy idafite alkali, umunyu n'indi myanda ntibyoroshye kwangirika. Igihe cyose ibitswe neza (bifunze, bidafite ubushuhe n'ubushyuhe bwinshi), igihe cyo kubibika ni umwaka 1. Nyuma y'itariki ntarengwa, niba igenzura ryemewe, riracyashobora gukoreshwa. Epoxy curing compound ifite ubushobozi bwo kudahinduka kw'imiti. Irwanya kwangirika kw'imiti ya alkali, aside, umunyu n'ibindi bikoresho ni byiza kuruta iya polyester resin idafite amazi, resine ya phenolic n'izindi resine zikoresha thermosetting. Kubwibyo, epoxy resin ikoreshwa cyane nk'icyitegererezo cyo kurwanya kwangirika. Kubera ko epoxy resin yavuwe ifite imiterere y'urusobe rw'ibice bitatu kandi ishobora kurwanya kwangirika kw'amavuta, ikoreshwa cyane mu rukuta rw'imbere rw'ibigega bya peteroli, amato ya peteroli n'indege.

Igishushanyo cya 1 umuyoboro w'umuriro (ibice 5)

(7) Ubushyuhe buterwa n'umusemburo wa epoxy muri rusange ni 80 ~ 100 ℃. Ubwoko bwa epoxy resin bushobora kwihanganira ubushyuhe bushobora kugera kuri 200 ℃ cyangwa hejuru yayo.
