Ikizamini cya Vacuum
Uburebure bwigice cyicyitegererezo ni (500 ± 50) mm.Koresha ingamba zikwiye kugirango uhagarike imiyoboro isohoka kandi isohoke, hanyuma wongere buhoro buhoro umuvuduko mubi uva kumurongo winjira kuri mm 660 mm hg, ubike muminota 1.Nyuma yikizamini, reba igifuniko cy'imbere, kandi ibisubizo by'ibizamini bigomba kubahiriza ibivugwa muri 5.10.
Ikizamini cyo hejuru
Uburebure bw'igice cy'icyitegererezo cyari (100 ± 10) mm.Icyitegererezo cyashyizwe muri incubator hanyuma gishyuha (300 ± 5) ℃ kuri 1 h.Noneho yakuweho akonjeshwa bisanzwe mubushyuhe busanzwe.Nyuma yikizamini, fata icyitegererezo hanyuma urebe igifuniko cyimbere (isura yijimye kandi yijimye biremewe), kandi ibisubizo byikizamini bigomba kubahiriza 5.11.
Ikizamini cyingutu
Uburebure bw'igice cy'icyitegererezo cyari (500 ± 50) mm.Hafashwe ingamba zikwiye zo guhagarika imiyoboro isohoka n’isohoka, kandi umuyoboro wahujwe na sisitemu yo gutanga amazi.Amazi yaruzuye kugirango akureho umwuka, hanyuma hakorwa ibizamini bya hydrostatike 3000 biva kuri (0.4 ± 0.1) MPa na MPa, kandi igihe cya buri kizamini nticyarenze s 2.Nyuma yikizamini, igipfundikizo cyimbere kigomba kugenzurwa kandi ikizamini cyo gufatira hamwe kizakorwa hashingiwe ku biteganywa na 6.4, kandi ibisubizo byikizamini bihuye nibiteganijwe 5.13.
Ikizamini cyizuba
Uburebure bw'igice cy'icyitegererezo cyari (500 ± 50) mm.Ingero zashyizwe kuri 24 h kuri buri bushyuhe muburyo bukurikira:

Nyuma yikizamini, icyitegererezo cyashyizwe mubidukikije bifite ubushyuhe bwa (20 ± 5) ℃ kuri 24 h.Igifuniko cy'imbere cyaragenzuwe kandi ikizamini cyo gufatira hamwe cyakozwe hakurikijwe ibivugwa muri 6.4.Ibisubizo by'ibizamini bigomba guhuza n'ibiteganijwe 5.14.
Ikizamini cyo gusaza amazi
Ingano n'uburebure bw'igice cy'icyitegererezo ni mm 100.Ibice byerekanwe kumpande zombi z'igice cy'umuyoboro bigomba kuvurwa na anticorrosion.Igice cy'umuyoboro kigomba gushirwa mumazi yatoboye kuri (70 ± 2) ℃ muminsi 30.
Ibiranga incamake yamakuru yatangajwe
(1) Ibikoresho byo hejuru.Epoxy resin ifite ubumwe bukomeye hamwe nuburyo bwimikorere ya molekile, bityo imiterere yubukanishi irarenze fenolike ya fenolike na polyester idahagije hamwe nibindi bikoresho bya termosetting.
(2) Umuyoboro wa plastiki wumuriro ukoresheje epoxy resin, hamwe na adhesion ikomeye.Sisitemu yo gukiza ya epoxy resin ikubiyemo itsinda rya epoxide ikora cyane, itsinda rya hydroxyl, ether bond, amine bond, ester bond hamwe nandi matsinda ya polar, biha epoxy ibikoresho byakize bifatanye neza nicyuma, ceramic, ikirahure, beto, ibiti nibindi bikoresho bya polar. .
(3) gukiza igipimo cyo kugabanuka ni gito.Muri rusange 1% ~ 2%.Ni bumwe mu bwoko butandukanye hamwe no kugabanya gukira kugabanuka muri resmosetting resin (resin fenolike ni 8% ~ 10%; resin ya polyester idahagije ni 4% ~ 6%; Silicone resin 4% ~ 8%).Coefficient yo kwagura umurongo nayo ni nto cyane, muri rusange 6 × 10-5 / ℃.Ijwi rero rihinduka bike nyuma yo gukira.
(4) Ikoranabuhanga ryiza.Epoxy resin ikiza mubyukuri ntabwo itanga ihindagurika rya molekile nkeya, bityo irashobora kuba umuvuduko muke cyangwa guhuza imashini.Irashobora gufatanya nubwoko bwose bwo gukiza kugirango itange umusemburo udafite imbaraga, muremure cyane, ifu yifu hamwe namazi ashingiye kumazi nibindi bitwikiriye ibidukikije.
(5) Gukoresha amashanyarazi meza cyane.Epoxy resin ni resimosetting resin ifite imiterere myiza ya antistatike.
(6) Guhagarara neza, kurwanya imiti.Epoxy resin idafite alkali, umunyu nibindi byanduye ntabwo byoroshye kwangirika.Igihe cyose kibitswe neza (gifunze, ntigiterwa nubushuhe, ntabwo kiri mubushyuhe bwinshi), igihe cyo kubika ni umwaka 1.Irashobora gukoreshwa niba yujuje ibisabwa nyuma yo kurangira.Epoxy ibikoresho byakize bifite imiti ihamye.Kurwanya kwangirika kwa alkali, aside, umunyu nibindi bitangazamakuru birutwa na polyester idahagije, resin ya fenolike nandi mashanyarazi.Kubwibyo rero, epoxy resin ikoreshwa cyane nka anticorrosive primer, kandi kubera ko epoxy resin ikiza ibikoresho ari imiterere y'urusobe rw'ibice bitatu, kandi irashobora kwihanganira kwinjiza amavuta, nibindi, umubare munini wibisabwa mumavuta ya peteroli, tanker ya peteroli, indege, the urukuta rw'imbere rutondekanye muri tank.
(7) Epoxy ikiza ubushyuhe ni 80 ~ 100 ℃.Epoxy resin irwanya ubushyuhe irashobora kugera kuri 200 ℃ cyangwa irenga.
Ibyiza byibicuruzwa
