Uburyo bwo guhuza umuyoboro wumuriro: urudodo, igikonjo, flange, nibindi. Ikemura byimazeyo ibibazo byinshi nko kwangirika kwangirika kwubutaka hamwe no gupima urukuta rwimbere rwibicuruzwa bisa nyuma yo kubikoresha igihe kirekire, kugirango hirindwe gukumira imbere bigira ingaruka kumikoreshereze, kugirango bitezimbere cyane mubuzima bwa serivisi bwimiyoboro idasanzwe irwanya umuriro. Bitewe no kongeramo ibikoresho bya flame retardant mubikoresho byo gutwikira, ubushyuhe bwubushyuhe bwibicuruzwa buratera imbere ugereranije nibindi bicuruzwa bisa. Kubwibyo, ntabwo bizahindura imikoreshereze mugihe ubushyuhe bwibidukikije buzamutse cyane. Ubuzima bwa serivisi n'imikorere y'imiyoboro yumuriro imbere no hanze iraruta cyane iy'imiyoboro ya galvanis. Ibara ritukura.

Uruganda rwacu ruzobereye mu gukora imiyoboro yumuriro, umuyoboro wibyuma, umuyoboro wifu wifu, umuyoboro wifu wifu nicyuma cya santimetero 6. Gusaba: gutanga amazi yumuriro, gutanga gaze hamwe na sisitemu yo gutwara abantu benshi. Ubwiza bwibicuruzwa butambutsa gasutamo kandi butsinda ibizamini byinshi mbere yo kuva muruganda. Kurikiza amahame yubuziranenge bwigihugu ndetse n’amahanga.

(1) Ibikoresho byo hejuru. Epoxy resin ifite ubumwe bukomeye hamwe nuburinganire bwa molekile yuzuye, kubwibyo imiterere yubukanishi irenze ibisigisigi rusange bya termosetting nka resin ya fenolike na polyester idahagije.

. Epoxy resin yo gukiza ikubiyemo itsinda rya epoxy, itsinda rya hydroxyl, ether bond, amine bond, ester bond hamwe nandi matsinda ya polar hamwe nibikorwa bikomeye, biha epoxy ibikiza byakize neza cyane ibyuma, ububumbyi, ibirahuri, beto, ibiti nibindi bikoresho bya polar.

(3) Kugabanya gukira kugabanuka. Muri rusange 1% ~ 2%. Ni bumwe mu bwoko butandukanye bwo gukiza kugabanutse hagati ya resmosetting (resin fenolike ni 8% ~ 10%; resin ya polyester idahagije ni 4% ~ 6%; silicone resin ni 4% ~ 8%). Coefficient yo kwagura umurongo nayo ni nto cyane, muri rusange 6 × 10-5 / ℃。 Kubwibyo, amajwi arahinduka gake nyuma yo gukira.

(4) Gukora neza. Epoxy resin mubusanzwe ntabwo itanga imbaraga nke za molekuline mugihe cyo gukira, bityo irashobora gukorwa munsi yumuvuduko muke cyangwa igitutu cyo guhura. Irashobora gufatanya nuburyo butandukanye bwo gukiza kugirango itange ibidukikije byangiza ibidukikije nkibidashobora gukemuka, binini cyane, ifu yifu hamwe n’amazi ashingiye ku mazi.

(5) Gukoresha amashanyarazi meza cyane. Epoxy resin ni resimosetting resin ifite imiterere myiza ya antistatike.

(6) Guhagarara neza no kurwanya imiti myiza. Epoxy resin idafite alkali, umunyu nibindi byanduye ntabwo byoroshye kwangirika. Igihe cyose kibitswe neza (gifunze, kitarimo ubushuhe nubushyuhe bwo hejuru), igihe cyo kubika ni umwaka 1. Nyuma yitariki yo kurangiriraho, niba igenzura ryujuje ibisabwa, rirashobora gukoreshwa. Epoxy ikiza ivanze ifite imiti ihamye. Kurwanya kwangirika kwa alkali, aside, umunyu nibindi bitangazamakuru nibyiza kuruta ibya poliester idahagije, resin ya fenolike nibindi bisigazwa bya termosetting. Kubwibyo, epoxy resin ikoreshwa cyane nka anti-ruswa. Kubera ko epoxy resin yakize ifite imiterere y'urusobekerane rwibice bitatu kandi irashobora kurwanya kwinjiza amavuta, ikoreshwa cyane murukuta rwimbere rwuzuyemo ibigega bya peteroli, tanker yamavuta nindege.

(7) Kurwanya ubushyuhe bwa epoxy curing compound muri rusange ni 80 ~ 100 ℃. Ubwoko butarwanya ubushyuhe bwa epoxy resin irashobora kugera kuri 200 ℃ cyangwa irenga.
