Impamvu zitera uduheri mu gihe cyo gukaraba:
Impamvu ituma uduce tw'ibitunguru dukora mu gihe cyo kuvangaresin ya epoxyKole ni uko iyo gaze ishyirwa mu gihe cyo gukangura ikora uduce duto. Indi mpamvu ni "ingaruka zo gukangura" ziterwa n'amazi akangurwa vuba cyane. Hari ubwoko bubiri bw'uduce duto: tugaragara n'ututagaragara. Gukoresha imashini ikuraho imyuka bishobora gukuraho uduce duto tugaragara gusa, ariko ntabwo bigira ingaruka nziza mu gukuraho uduce duto tudashobora kubonwa n'amaso y'umuntu.
Impamvu zitera uduheri mu gihe cyo gukaraba:
Ibi biterwa nuko epoxy resin ivurwa na polymerization, ikaba ari reaction ya chemical. Mu gihe cyo gucukura, utubuto duto muri sisitemu ya epoxy resin turashyuha kandi tukongera kwiyongera, maze iyo gaze ntibe ikijyanye na sisitemu ya epoxy, hanyuma igakorana hamwe kugira ngo ikore utubuto tunini.
Impamvu zitera ifuro rya epoxy resin:
(1) Imiterere y'ibinyabutabire idahamye
(2) Kuvanga iyo utegura icyuma gikonjesha
(3) Gukuramo ifuro nyuma yo gukusanya ibikoresho binini
(4) Uburyo bwo gusohora urusenda
Ingaruka zo kuvanga epoxy resin:
(1) Ifuro ritera kuzura no gukoresha cyane, ibyo bizagira ingaruka ku burebure bw'amazi aboneka.
(2) Uduce duterwa n'uturemangingo tw'amine dutuma ibintu bikira bizagira ingaruka ku mikorere myiza y'inyubako.
(3) Kuba hariho "udupira tw'amazi" bizatuma VCM gas phase polymerization, muri rusange ikorerwa mu gikoresho gifata.
(4) Iyo udupfundo tudakuweho burundu mu gihe cyo kubaka, udupfundo tuzavuka nyuma yo gushonga, kandi hazaba hari utwobo twinshi hejuru nyuma yo kuma, ibyo bizagira ingaruka zikomeye ku bwiza bw'umusaruro.
Ni gute wakuraho utubumbe tw'umwuka?
Ibyiciro by'ibicuruzwa bikoreshwa mu gusukura amazi: ibikoresho bisukura amazi bya silicone, ibikoresho bisukura amazi bitari silicone, ibikoresho bisukura amazi bya polyether, ibikoresho bisukura amavuta y'ubutare, ibikoresho bisukura amazi ya alcohol nyinshi, nibindi.
Iyo ubushyuhe buri hasi, imiterere y'ibintu byinshi by'amazi Impinduka zibaho, cyane cyane ubushyuhe bw'ibintu by'amazi bifatanye buziyongera uko ubushyuhe bugabanuka.Kole ya epoxy resin ab, nk'ikintu gisanzwe cy'amazi, gifite ukwiyongera gukomeye mu gaciro ka viscosity bitewe n'igabanuka ry'ubushyuhe. Kubwibyo, mu gihe cyo gukoresha no gukoresha, uduce duto turagorana gukuraho, imikorere yo kugorora iragabanuka, kandi ukwiyongera kw'igihe cyo gukoresha n'igihe cyo gukonja ntibifasha mu gukora no kugenzura bisanzwe. Ariko, binyuze mu kwegeranya uburambe bw'imyaka myinshi mu gukora, twatanze incamake y'uburambe bumwe na bumwe bufasha mu gukemura no kugabanya ibibazo biterwa n'ibibazo byavuzwe haruguru. By'umwihariko, hari uburyo bune bukurikira:
1. Uburyo bwo gushyushya aho akazi gakorerwa:
Iyo ubushyuhe bw'aho akazi kabereye bugabanutse bukagera kuri 25°C, gushyushya neza aho akazi kakorerwa birakenewe kugira ngo ubushyuhe bugere ku bushyuhe bukwiriye gukoreshwa muri kole (25°C ~ 30°C). Muri icyo gihe, ubushyuhe bw'umwuka aho akazi kakorerwa bugomba kuguma kuri 70% cyangwa birengaho, kugeza igihe ubushyuhe bwa kole ubwayo buzaba bumwe n'ubushyuhe bw'ikirere mbere yuko kole ikora kandi igakoreshwa neza.
Icyibutso gishyushye: Ubu buryo ni bwo buryo bwiza cyane, ariko ikiguzi cyo gukoresha kizaba kiri hejuru, nyamuneka witondere ibaruramari ry'ibiciro.
2. Uburyo bwo gushyushya amazi abira:
Gukonjesha bizagabanya mu buryo butaziguye agaciro k'ubushyuhe bwaresin ya epoxyKole yo mu bwoko bwa ab hanyuma ukayiyongera cyane. Gushyushya mbere y'igihe mbere yo gukoresha kole byongera ubushyuhe bwayo kandi bigabanye agaciro ka viscosity, bityo bikaba byoroshye kuyikoresha. Uburyo bwihariye ni ugushyira agacupa kose ka kole mu mazi abira hanyuma ugashyushya amasaha 2 mbere yo gukoresha kole, kugira ngo ubushyuhe bwa kole bugere kuri 30°C, hanyuma ukayikuramo, ukayizunguza kabiri, hanyuma ukayigumisha A ku bushyuhe butari munsi ya 30°C mu mazi ashyushye hanyuma ukoreshe mu gihe ushyushya. Mu gihe cyo kuyikoresha, kuramo kole hanyuma uyizunguze buri minota 30 kugira ngo ubushyuhe n'imiterere ya kole bigumane. Ariko witondere cyane kole iri mu ndobo cyangwa icupa igumane n'amazi, bitabaye ibyo bizatera ingaruka mbi cyangwa zikomeye.
Icyibutso gishyushye: Ubu buryo bworoshye, buhendutse kandi bufatika, kandi ikiguzi n'ibikoresho biroroshye cyane. Ariko, hari ingorane zihishe, zikwiye kwitabwaho.
3. Uburyo bwo gushyushya mu ifuru:
Abakoresha bafite ubwo bufasha bashobora gukoresha epoxy resin ab kugira ngo bashyushye kole mu ifuru mbere yo gukoresha kole kugira ngo birinde kole ku buryo butunguranye. Biroroshye cyane. Uburyo bwihariye ni uguhindura ubushyuhe bw'ifuru kugeza kuri 60°C, hanyuma ugashyira agacupa kose ka kole mu ifuru kugira ngo ushyushye mbere, kugira ngo ubushyuhe bwa kole ubwayo bugere kuri 30°C, hanyuma ukuremo kole uyinyeganyeze kabiri, hanyuma ugashyira kole ku bushyuhe bwa 30°C hagati mu ifuru ukoresheje impande zishyushye, ariko witondere gukuramo kole uyinyeganyeze mu gihe cy'isaha imwe kugira ngo kole ihore ihorana ubushyuhe bungana n'ibiyigize.
Icyibutso gishyushye: Ubu buryo buzongera ikiguzi gato, ariko bworoshye kandi bufite akamaro.
4. Uburyo bwo gufasha abakoresha imiti igabanya ububabare:
Kugira ngo wihutishe gukuraho utubumbe mu buryo buciriritse, ushobora kandi kugura ikintu cyihariye cyo gukuraho ifu cya kole ya epoxy resin ab-yongeweho, hanyuma ukongeramo kole ya A ifite igipimo cya 3‰ imbere, uburyo bwihariye; ntushyiremo kole irenze 3% kuri kole ya A ishyushye hakoreshejwe uburyo bwavuzwe haruguru. Ikintu cyihariye cyo gukuraho ifu cyakole ya epoxy resin AB, hanyuma uvange neza hanyuma uvange na kole ya B kugira ngo ukoreshe.
