Ibyiza nibibi byombi byagereranijwe kuburyo bukurikira:
Kurambika intoki ni inzira ifunguye kugeza ubu igera kuri 65% yafibreimbaraga za polyester. Ibyiza byayo nuko ifite umudendezo munini mubwisanzure muguhindura imiterere, igiciro cyibiciro ni gito, guhuza n'imihindagurikire birakomeye, imikorere yibicuruzwa bizwi nisoko, kandi ishoramari ni rito. Birakwiriye rero cyane cyane ku masosiyete mato, ariko kandi no mu nganda zo mu nyanja no mu kirere, aho usanga ari igice kinini. Ariko, hariho kandi urukurikirane rwibibazo muriki gikorwa. Niba imyuka ihindagurika ihindagurika (VOC) irenze igipimo gisanzwe, igira ingaruka zikomeye kubuzima bwabakozi, biroroshye gutakaza abakozi, hariho byinshi bibujijwe kubikoresho byemewe, imikorere yibicuruzwa ni bike, kandi ibisigazwa biraseswa. kandi ikoreshwa ku bwinshi, cyane cyane ibicuruzwa. Ubwiza ntibuhungabana. Umubare wafibre na resin, ubunini bwibice, igipimo cyibikorwa byurwego, hamwe nuburinganire bwurwego byose bigira ingaruka kubakoresha, kandi uyikoresha asabwa kugira ikoranabuhanga ryiza, uburambe nubuziranenge.Ibisigariraibikubiye mu ntoki zashyizwe mu ntoki muri rusange ni 50% -70%. Imyuka ya VOC yo gufungura ifu irenga 500PPm, kandi guhindagurika kwa styrene ni hejuru ya 35% -45% byamafaranga yakoreshejwe. Amabwiriza y'ibihugu bitandukanye ni 50-100PPm. Kugeza ubu, ibihugu byinshi by’amahanga bikoresha cyclopentadiene (DCPD) cyangwa ibindi bisigazwa bya styrene nkeya, ariko nta cyiza gisimbuza styrene nka monomer.
Mat uburyo bwo gushyira amaboko
Icyuhouburyo bwo kumenyekanisha nuburyo buhendutse bwo gukora bwateye imbere mumyaka 20 ishize, cyane cyane bubereye gukora ibicuruzwa binini. Ibyiza byayo ni ibi bikurikira:
(1) Igicuruzwa gifite imikorere myiza numusaruro mwinshi.Mugihe kimwefiberglassibikoresho fatizo, imbaraga, gukomera hamwe nibindi bintu bifatika bya vacuum resin-byinjijwemo bishobora gutezimbere hejuru ya 30% -50% ugereranije nibiganza byashyizweho (Imbonerahamwe 1). Ibikorwa bimaze guhagarara, umusaruro urashobora kuba hafi 100%.

(2) Ubwiza bwibicuruzwa burahagaze kandi gusubiramo nibyiza.Ubwiza bwibicuruzwa ntibwangizwa nabakoresha, kandi hariho urwego rwo hejuru rwo guhuzagurika niba arikintu kimwe cyangwa hagati yibigize. Ibiri muri fibre yibicuruzwa byashyizwe mububiko ukurikije umubare wabigenewe mbere yo gutera inshinge, kandi ibigize bifite igipimo gisanzwe gihoraho, muri rusange 30% -45%, bityo rero guhuza no gusubiramo imikorere yibicuruzwa ni byiza kuruta intoki zashyizweho. byinshi, kandi bike.
(3) Imikorere yo kurwanya umunaniro iratera imbere, ishobora kugabanya uburemere bwimiterere.Bitewe nibirimo fibre nyinshi, porotike nkeya nibikorwa byinshi, cyane cyane kunoza imbaraga za interlaminar, kurwanya umunaniro wibicuruzwa biratera imbere cyane. Mugihe cyingufu zimwe cyangwa ibikenewe bisabwa, ibicuruzwa bikozwe na vacuum induction birashobora kugabanya uburemere bwimiterere.
(4) Ibidukikije.Uburyo bwa vacuum resin infusion ni inzira ifunze aho ibinyabuzima bihindagurika hamwe n’imyuka ihumanya ikirere bigarukira mu gikapu cya vacuum. Gusa umubare wibintu bihindagurika uhari mugihe pompe ya vacuum ihinduwe (kuyungurura) hanyuma ingunguru ya resin ikingurwa. Imyuka ya VOC ntabwo irenga igipimo cya 5PPm. Ibi kandi bitezimbere cyane ibidukikije byakazi kubakoresha, bigahindura abakozi, kandi bikagura ibikoresho biboneka.
(5) Ubusugire bwibicuruzwa nibyiza.Inzira yo gutangiza vacuum irashobora gukora imbavu zishimangira, imiterere ya sandwich nibindi byinjizwamo icyarimwe, ibyo bikaba bitezimbere ubusugire bwibicuruzwa, bityo ibicuruzwa binini nkibikoresho byabafana, ubwato bwubwato hamwe nubwubatsi bushobora gukorwa.
(6) Kugabanya ikoreshwa ryibikoresho fatizo nakazi.Muburyo bumwe, ingano ya resin yagabanutseho 30%. Imyanda mike, igihombo cya resin kiri munsi ya 5%. Umusaruro mwinshi w'abakozi, kuzigama abakozi barenga 50% ugereranije nuburyo bwo gushyira amaboko. Cyane cyane mugushushanya geometrike nini kandi igoye ya sandwich hamwe nibice byubatswe byubatswe, ibikoresho no kuzigama abakozi birarenze. Kurugero, mugukora ingendo zihagaritse munganda zindege, igiciro cyo kugabanya ibyuma bifata 365 kigabanukaho 75% ugereranije nuburyo gakondo, uburemere bwibicuruzwa ntibuhinduka, kandi imikorere ni nziza.
(7) Ibicuruzwa bisobanutse neza.Ibipimo bifatika (ubunini) bwibicuruzwa bya vacuum resin yo gutangiza ibicuruzwa nibyiza kuruta ibicuruzwa byashyizwe mu ntoki. Muburyo bumwe, ubunini bwibicuruzwa rusange bya vacuum resin ikwirakwizwa ni 2/3 byibicuruzwa byashyizwe mu ntoki. Gutandukana kwibicuruzwa bigera kuri ± 10%, mugihe uburyo bwo kurambika intoki muri rusange ± 20%. Uburinganire bwibicuruzwa hejuru biruta ibyo kurambika amaboko. Urukuta rw'imbere rw'ibicuruzwa biva muri vacuum resin uburyo bwo kumenyekanisha biroroshye, kandi ubusanzwe ubusanzwe bugizwe na resin ikungahaye cyane, bidasaba ikote ryo hejuru. Kugabanya imirimo nibikoresho byo gutunganya no gushushanya.
Birumvikana ko gahunda yo gutangiza vacuum resin nayo ifite ibitagenda neza:
(1) Igikorwa cyo kwitegura gifata igihe kirekire kandi kiragoye.Gushyira muburyo bukwiye, gushyira ibitangazamakuru byerekanwa, imiyoboro yo gutandukana, gufunga vacuum neza, nibindi birakenewe. Kubwibyo, kubicuruzwa bito-binini, igihe cyo gukora ni kirekire kuruta uburyo bwo gushyira amaboko.
(2) Igiciro cy'umusaruro ni kinini kandi imyanda myinshi irabyara.Ibikoresho bifasha nka firime ya vacuum, imashini itandukanya, imyenda yo kurekura hamwe nuyoboro wa diverion byose birashobora gutabwa, kandi ibyinshi muri byo ubu bitumizwa mu mahanga, bityo igiciro cy’umusaruro kikaba kinini kuruta uburyo bwo gushyira amaboko. Ariko uko ibicuruzwa binini, niko itandukaniro rito. Hamwe no kwifashisha ibikoresho bifasha, iri tandukaniro ryibiciro riragenda riba rito. Ubushakashatsi buriho kubikoresho byingirakamaro bishobora gukoreshwa inshuro nyinshi nicyerekezo cyiterambere cyiki gikorwa.
(3) Gukora inzira bifite ingaruka zimwe.Cyane cyane kubicuruzwa binini kandi bigoye byubatswe, iyo resin infusion imaze kunanirwa, ibicuruzwa biroroshye gukurwaho.
Kubwibyo, ubushakashatsi bwibanze bwibanze, kugenzura neza ingamba hamwe ningamba zifatika zo gukosora birasabwa kugirango inzira igerweho.
Ibicuruzwa byacu:
Kugenda kwa fibre, fiberglasskuboha, materi ya fiberglass, fiberglass mesh umwenda,poliester idahagije, vinyl ester resin, epoxy resin, gel coat resin, umufasha wa FRP, fibre karubone nibindi bikoresho bya FRP.
