1. Uruhare rwo kuzuza ibikoresho
Ongeramo ibyuzuza nka calcium karubone, ibumba, hydroxide ya aluminium, flake y'ibirahure, microbead y'ibirahure, na lithopone kuri resin ya polyester hanyuma ubisasa kugirango ukore imvange ya resin.Imikorere yacyo niyi ikurikira:
(1) Kugabanya igiciro cyibikoresho bya FRP (nka karubone ya calcium na ibumba);
.
(3) Kunoza ibishishwa bya resin mugihe cyo kubumba no kwirinda gutonyanga.Ariko, twakagombye kumenya ko kwiyongera gukabije kwijimye bishobora rimwe na rimwe kuba bibi;
(4) Kudakorera mu mucyo ibicuruzwa byakozwe (nka calcium karubone n'ibumba);
(5) Kwera ibicuruzwa byakozwe (nka barium sulfate na lithopone);
(6) Kunoza ruswa irwanya ibicuruzwa byakozwe (mika, amabati, nibindi);
.
(8) Kunoza ubukana nubukomere bwibicuruzwa byakozwe (nka calcium karubone, microsperes yikirahure, nibindi);
(9) Kunoza imbaraga zibicuruzwa byakozwe (ifu yikirahure, potasiyumu titanate fibre, nibindi);
(10) Kunoza imitwaro yoroheje nubushakashatsi bwibicuruzwa byakozwe (microsperes zitandukanye);
(11) Tanga cyangwa wongere thixotropy yimvange ya resin (nka ultrafine anhydrous silica, ifu yikirahure, nibindi).
Birashobora kugaragara ko intego yo kongeramo ibyuzuye mubisigazwa bitandukanye, bityo rero ni ngombwa guhitamo ibyuzuza ukurikije intego zitandukanye kugirango ukoreshe byimazeyo uruhare rwuzuza.
2. Kwirinda guhitamo no gukoresha ibyuzuye
Hariho ubwoko butandukanye bwuzuza.Kubwibyo, birakenewe guhitamo ikirango gikwiye cyuzuzwa nicyiciro kugirango ukoreshe, bigenda ntavuze.Icyitonderwa muri rusange mugihe uhitamo ibyuzuza ntabwo ari uguhitamo gusa ibiciro hamwe nigiciro cyagenwe mbere, ahubwo ni no kwitondera ingingo zikurikira:
(1) Ingano ya resin yakiriwe igomba kuba mike.Ingano ya resin yakiriwe igira ingaruka zikomeye kumyumvire yimvange ya resin.
(2) Ubukonje bwimvange ya resin bugomba kuba bukwiye kubikorwa byo kubumba.Guhindura byinshi muburyo bwo kwivanga kwa resin bishobora gukorwa muguhuza na styrene, ariko kongeramo byinshi byuzuza no kuvanga na styrene bizatuma igabanuka ryimikorere ya FRP.Ubukonje bwimvange ya resin rimwe na rimwe bigira ingaruka cyane kumavanga, kuvanga imiterere, cyangwa kongeramo ibintu byuzuza ibintu.
(3) Ibiranga gukira biranga ivangwa rya resin bigomba kuba bikwiranye nuburyo bwo kubumba.Ibiranga gukira bivangwa na resin bivangwa rimwe na rimwe biterwa nuwuzuza ubwayo cyangwa amatangazo yamamaza cyangwa avanze n’ibintu by’amahanga mu kuzuza.
(4) Uruvange rwa resin rugomba kuguma ruhagaze neza mugihe runaka.Kubintu byo gutuza no gutandukanya abuzuza bitewe no guhagarara, birashobora rimwe na rimwe gukumirwa guha resin hamwe na thixotropy.Rimwe na rimwe, uburyo bwo kwirinda uburyo buhoraho kandi bukomeza gukanika imashini nabwo bukoreshwa mukurinda gutuza kwuzuza, ariko muriki gihe, birakenewe ko harebwa gukumira gutuza no kwegeranya ibyuzuye mu muyoboro uva muri kontineri irimo ivangavanga kugeza kubikora urubuga.Iyo microbead yuzuza ikunda gutandukana hejuru, birakenewe kwemeza amanota.
.Kwiyongera kwuzuza mubisanzwe bigabanya gukorera mu mucyo wa resin kandi bikanagabanya guhindagurika kwa resin mugihe cyo gutera.Kubwibyo, gutera akabariro, gusebanya, no guca imanza mugihe cyo kubumba byabaye ingorabahizi.Izi ngingo zigomba gusuzumwa kugirango hamenyekane igipimo cyimvange ya resin.
(6) Hagomba kwitonderwa uburemere bwihariye bwimvange ya resin.Iyo ukoresheje ibyuzuye nkibikoresho byiyongera kugirango ugabanye ibiciro, uburemere bwihariye bwimvange ya resin bwiyongera ugereranije na resin, rimwe na rimwe ntibujuje agaciro kateganijwe ko kugabanya byimazeyo ibiciro.
(7) Ingaruka zo guhindura isura yuzuza zigomba gushakishwa.Guhindura hejuru yubutaka bigira akamaro mukugabanya ubukonje bwimvange ya resin, kandi abahindura ibintu bitandukanye barashobora rimwe na rimwe kunoza imbaraga za mashini hiyongereyeho kurwanya amazi, kurwanya ikirere, no kurwanya imiti.Hariho kandi ubwoko bwuzuza bwakorewe hejuru yubutaka, kandi bamwe bakoresha icyo bita "uburyo bwo kuvanga uburyo" kugirango bahindure ubuso bwuzuye.Nukuvuga ko, iyo kuvanga resin ivanze, ibyuzuza nabahindura byongewe hamwe kuri resin, rimwe na rimwe ingaruka ni nziza cyane.
(8) Kwangiza ibintu bivanze na resin bigomba gukorwa neza.Kuzuza akenshi bikoreshwa muburyo bwa poro ya micro nuduce, hamwe nubuso bunini cyane.Muri icyo gihe, hari n'ibice byinshi aho ifu ya micro nuduce twiteranya hamwe.Kugirango ukwirakwize ibyo byuzuza muri resin, resin igomba gukenera cyane, kandi umwuka ukururwa muruvange.Mubyongeyeho, umwuka nawo ukururwa mubunini bunini bwuzuza.Kubera iyo mpamvu, umwuka utagereranywa w’umwuka wavanze mu mvange yateguwe, kandi muri iyi leta, FRP yabonetse mu kuyitanga kugirango ikorwe ikunda kubyara ibibyimba n’ubusa, rimwe na rimwe ikananirwa kugera ku bikorwa byateganijwe.Mugihe bidashoboka gusebanya byuzuye uhagaze gusa nyuma yo kuvanga, gushungura imifuka ya silike cyangwa kugabanya umuvuduko birashobora gukoreshwa mugukuraho ibibyimba.
Usibye ingingo zavuzwe haruguru, ingamba zo gukumira ivumbi nazo zigomba gufatwa mubidukikije aho ukoresha zuzuza.Ibintu nka ultrafine selile silika igizwe na silika yubusa, alumina, isi ya diatomaceous, amabuye akonje, nibindi byashyizwe mu mukungugu wo mu cyiciro cya mbere, naho calcium karubone, ifu yikirahure, ibirahuri, mika, nibindi byashyizwe mu mukungugu wo mu cyiciro cya II.Hariho kandi amabwiriza yerekeranye nubushakashatsi bugenzurwa nifu ya mikoro itandukanye mubidukikije.Ibikoresho byaho bigomba gushyirwaho kandi ibikoresho byo gukingira abakozi bigomba gukoreshwa cyane mugihe ukoresha ifu yuzuye.
