Impamvu zibibyimba mugihe cyo gukurura:
Impamvu ituma ibibyimba bitangwa mugihe cyo kuvangaepoxy resinkole ni uko gaze yatangijwe mugihe cyo gukurura ibyara. Indi mpamvu ni "cavitation effect" iterwa n'amazi akangurwa vuba. Hariho ubwoko bubiri bwibibyimba: bigaragara kandi bitagaragara. Gukoresha vacuum degassing birashobora gukuraho gusa ibibyimba bigaragara, ariko ntabwo bigira akamaro mugukuraho utubuto duto tutagaragara kumaso yumuntu.
Impamvu zibibyimba mugihe cyo gukira:
Ni ukubera ko epoxy resin yakize na polymerisation, ni reaction ya chimique. Mugihe cyo gukira, utubuto duto muri epoxy resin sisitemu yubushyuhe no kwaguka, kandi gaze ntigishobora guhuzwa na sisitemu ya epoxy, hanyuma igahurira hamwe kugirango ikore ibibyimba binini.
Impamvu zitera epoxy resin ifuro:
(1) Imiterere yimiti idahindagurika
(2) Kuvanga mugihe utegura umubyimba
(3) Kubira ifuro nyuma yo gukusanya umubyimba
(4) Uburyo bwo gusohora buhoro
Ibyago bya epoxy resin ifuro mugihe cyo kuvanga:
.
(2) Ibibyimba biterwa no gukiza agent molekile amine bizagira ingaruka kubikorwa byubwubatsi.

Nigute ushobora kuvanaho umwuka mwinshi?
Ibicuruzwa bisanzwe bikoreshwa mu gusebanya ibyiciro byibicuruzwa: ibikoresho bya silicone defoaming, ibikoresho bitarimo silicon, ibikoresho byo gusebanya polyether, ibikoresho byangiza amavuta yubutare, ibiyobyabwenge byangiza karubone nyinshi, nibindi.
Iyo ubushyuhe buri hasi, ibiranga ibintu byinshi byamazi Impinduka zizabaho, cyane cyane ubwiza bwibintu bifata amazi biziyongera uko ubushyuhe bugabanuka.Epoxy resin ab glue, nkibintu bisanzwe byamazi, bifite ubwiyongere bugaragara bwagaciro keza kubera kugabanuka kwubushyuhe. Kubwibyo, mugihe cyo gukoresha no gukoresha, ibituba biragoye kubikuraho, imikorere yo kugorora iragabanuka, kandi kwiyongera kwigihe cyo gukoresha nigihe cyo gukiza ntabwo bifasha umusaruro usanzwe no kugenzura. Ariko, binyuze mu kwegeranya imyaka myinshi yuburambe ku musaruro, twavuze muri make uburambe bwingirakamaro kugirango dukemure neza kandi tugabanye ibibazo biterwa nibibazo byavuzwe haruguru. By'umwihariko, hari uburyo bune bukurikira:
1. Uburyo bwo gushyushya ikibanza cyakazi:
Iyo ubushyuhe ku kazi bugabanutse kugera kuri 25 ° C, hasabwa gushyushya neza aho ukorera kugirango ubushyuhe bugere ku bushyuhe bukwiranye no gukora kole (25 ° C ~ 30 ° C). Muri icyo gihe, ubuhehere bugereranije n’ikirere ku kazi bugomba kubikwa kuri 70%. cyangwa rero, kugeza igihe ubushyuhe bwa kole ubwabwo bumeze nkubushyuhe bwibidukikije mbere yuko kole ikora kandi igakoreshwa neza.
Kwibutsa neza: Ubu buryo nuburyo bwiza cyane, ariko ikiguzi cyo gukora kizaba kinini, nyamuneka witondere kubara ibiciro.
2. Uburyo bwo gushyushya amazi:
Gukonjesha bizagabanya mu buryo butaziguye agaciro ka viscosity yaepoxy resinab kole kandi ikiyongera cyane. Gushyushya mbere yo gukoresha kole bizongera ubushyuhe bwacyo kandi bigabanye agaciro ka viscosity, byoroshye gukoresha. Uburyo bwihariye nugushira ingunguru yose cyangwa icupa rya kole mumazi abira hanyuma ukabishyushya amasaha agera kuri 2 mbere yo gukoresha kole, kugirango ubushyuhe bwa kole bugere kuri 30 ℃, hanyuma ubisohokane, ubinyeganyeze kabiri, hanyuma ugumane kole mubushyuhe butari munsi ya 30 ℃ mumazi ashyushye hanyuma ukoreshe mugihe ushyushye. Mugihe cyo kuyikoresha, fata kole hanyuma uyinyeganyeze buri saha nigice kugirango ubushyuhe nuburinganire bwa kole bihuze. Ariko witondere cyane cyane kutareka kole iri mu ndobo cyangwa icupa ifata amazi, bitabaye ibyo bizatera ingaruka mbi cyangwa zikomeye.
Kwibutsa neza: Ubu buryo buroroshye, bwubukungu kandi bufatika, kandi ibiciro nibikoresho biroroshye. Ariko, hariho akaga kihishe, kagomba kwitabwaho.
3. Uburyo bwo gushyushya amashyiga:
Abakoresha bafite ibyangombwa barashobora gukoresha epoxy resin ab kugirango bashyushya kole a mu ziko mbere yo gukoresha kole kugirango birinde guhura nimpanuka namazi. Biroroshye cyane. Uburyo bwihariye ni uguhindura ubushyuhe bwitanura kugeza kuri 60 ° C, hanyuma ugashyira ingunguru yose cyangwa icupa rya kole yose mu ziko kugirango ushushe, kugirango ubushyuhe bwa kole ubwabwo bugere kuri 30 ° C, hanyuma ukuremo kole hanyuma uyizunguze kabiri, hanyuma ushyire kole ku bushyuhe bwa Guhindura kugeza kuri 30 ° C hagati yitanura kugirango ushireho kole kugirango ushireho kole kugirango ushireho umuyaga. ubushyuhe bungana hamwe nibigize.
Kwibutsa neza: Ubu buryo nabwo buzamura igiciro gito, ariko biroroshye kandi byiza.
4. Uburyo bwo gutesha agaciro abakozi:
Kugirango wihute muburyo bwo gukuraho ibibyimba byinshi, urashobora kandi kugura umukozi udasanzwe wo gusebanya kuri epoxy resin ab-wongeyeho kole, hanyuma ukongeramo kole ifite igipimo cya 3 ‰ imbere, uburyo bwihariye; mu buryo butaziguye ongeraho bitarenze 3% bya kole kuri kole yashyutswe nuburyo bwavuzwe haruguru. Umukozi udasanzwe wo gusebanya kuriepoxy resin AB glue, hanyuma ukangure neza hanyuma uvange na B kole kugirango ukoreshe.
