Ukubeka izandla kuyinqubo yokubumba ye-FRP elula, eyongayo futhi ephumelelayo engadingi amathuluzi amaningi kanye nokutshalwa kwezimali futhi ingazuza imbuyiselo yemali ngesikhathi esifushane.
1.Ukufafaza nokudweba kwejazi lejeli
Ukuze kuthuthukiswe futhi kuhlobise isimo esingaphezulu semikhiqizo ye-FRP, kwandiswe inani lomkhiqizo, kanye nokuqinisekisa ukuthi ungqimba lwangaphakathi lwe-FRP aluguguleka futhi lwandise impilo yesevisi yomkhiqizo, indawo yokusebenza yomkhiqizo ngokuvamile yenziwa ungqimba olunameke nge-pigment (ukunamathisela kombala), okuqukethwe kwe-resin ephezulu kwesendlalelo sokunamathisela, kungaba yinhlaka ehlanzekile, kodwa futhi ithuthukiswe ngengaphezulu. Lolu ngqimba lubizwa ngokuthi ungqimba lwejazi lwejazi (olubizwa nangokuthi ungqimba olungaphezulu noma ungqimba lokuhlobisa). Izinga le-gel coat layer lithinta ngqo ikhwalithi yangaphandle yomkhiqizo kanye nokumelana nesimo sezulu, ukumelana kwamanzi nokumelana nokuguguleka kwemidiya yamakhemikhali, njll. Ngakho-ke, amaphuzu alandelayo kufanele aqashelwe lapho ufufaza noma udweba isendlalelo sejazi le-gel.
2.Ukunqunywa komzila wenqubo
Umzila wenqubo uhlobene nezici ezihlukahlukene njengekhwalithi yomkhiqizo, izindleko zomkhiqizo kanye nomjikelezo wokukhiqiza (ukusebenza kahle kokukhiqiza). Ngakho-ke, ngaphambi kokuhlela ukukhiqiza, kuyadingeka ukuba nokuqonda okuphelele kwezimo zobuchwepheshe (indawo, izinga lokushisa, okuphakathi, umthwalo ……, njll.), isakhiwo somkhiqizo, inani lokukhiqiza kanye nezimo zokwakha lapho umkhiqizo usetshenziswa, futhi ngemva kokuhlaziywa nokucwaninga, ukuze kunqunywe uhlelo lwenqubo yokubumba, ngokuvamile, izici ezilandelayo kufanele zicatshangelwe.
3.Okuqukethwe okuyinhloko komklamo wenqubo
(1) Ngokwezidingo zobuchwepheshe zomkhiqizo ukukhetha izinto ezifanele (izinto zokuqinisa, izinto zokwakha kanye nezinye izinto ezisizayo, njll.). Ekukhetheni izinto zokusetshenziswa, izici ezilandelayo zibhekwa ngokuyinhloko.
① Ukuthi umkhiqizo uxhumene ne-asidi nemidiya ye-alkaline, uhlobo lwemidiya, ukugxilisa ingqondo, izinga lokushisa lokusebenzisa, isikhathi sokuxhumana, njll.
②Kungakhathaliseki ukuthi kunezidingo zokusebenza ezifana nokudluliswa kokukhanya, i-flame retardant, njll.
③Ngokwezakhiwo zokushintshwa, noma ngabe umthwalo oguqukayo noma omile.
④Ngokuvinjelwa noma ngaphandle kokuvuza nezinye izidingo ezikhethekile.
(2) Nquma ukwakheka kwesikhunta kanye nempahla.
(3) Ukukhethwa kwe-ejenti yokukhulula.
(4) Nquma indlela yokwelapha ye-resin efanelekile kanye nesistimu yokwelapha.
(5) Ngokuhambisana nezidingo zokuqina komkhiqizo onikeziwe, nquma izinhlobonhlobo zezinto zokuqinisa, imininingwane, inani lezendlalelo kanye nendlela yokubeka izendlalelo.
(6) Ukulungiswa kwezinqubo zenqubo yokubumba.
4. Uhlelo lokunamathisela ungqimba lwepulasitiki oluqiniswe nge-fiber yengilazi
Hand lay-up kuyinkqubo ebalulekile isandla unama inqubo ukubumba, kumele kube operation emihle ukuze kuzuzwe okusheshayo, olunembile, iyunifomu resin okuqukethwe, akukho Bubbles sobala, akukho impregnation abampofu, akukho umonakalo fibre futhi umkhiqizo surface flat, ukuqinisekisa izinga imikhiqizo. Ngakho-ke, nakuba umsebenzi we-gluing ulula, akulula kakhulu ukwenza imikhiqizo kahle, futhi kufanele ithathwe ngokungathí sina.
(1) Ukulawula ukujiya
I-fiber yengilaziukulawulwa kokuqina kwemikhiqizo yepulasitiki okuqinisiwe, ukwakheka kwenqubo yokunamathisela ngesandla kanye nenqubo yokukhiqiza izohlangabezana nezinkinga zobuchwepheshe, lapho sazi ubukhulu obudingekayo bomkhiqizo, kuyadingeka ukubala ukuze kunqunywe i-resin, okuqukethwe kokugcwalisa kanye nezinto eziqinisayo ezisetshenziswa ekucacisweni, inani lezendlalelo. Bese ubala ukujiya kwayo okucishe kufane ngokuya ngefomula elandelayo.
(2) Ukubalwa komthamo we-resin
Umthamo we-resin we-FRP iyipharamitha yenqubo ebalulekile, engabalwa ngezindlela ezimbili ezilandelayo.
A ibalwa ngokuvumelana nesimiso sokugcwaliswa kwegebe, ifomula yokubala inani le-resin, yazi kuphela ubukhulu bendawo yeyunithi yendwangu yengilazi kanye nobukhulu obulinganayo (ungqimba lwe-resin).ingilazii-fiberindwangu okulingana nobukhulu bomkhiqizo), ungakwazi ukubala inani le-resin equkethwe ku-FRP
B ibalwa ngokuqala ngokubala isisindo somkhiqizo kanye nokuthola iphesenti lokuqukethwe kwe-glass fiber mass.
(3)Ingilazii-fiberuhlelo lokunamathisela indwangu
Imikhiqizo ene-gelcoat layer, i-gelcoat ayikwazi ukuxutshwa nokungcola, unamathisele ngaphambi kokuba uhlelo luvimbele ukungcola phakathi kwesendlalelo se-gelcoat kanye nesendlalelo esisekelayo, ukuze kungabangeli ukuhlangana okubi phakathi kwezingqimba, futhi kuthinte izinga lemikhiqizo. Isendlalelo sejazi lejeli singathuthukiswaphezuluumata. Isistimu yokunamathisela kufanele inake ukufakwa kwe-resin ye-fiber fibers, okokuqala yenza ukungena kwe-resin yonke indawo ye-fiber bundle, bese wenza umoya ongaphakathi kwe-fiber bundle ushintshwe ngokuphelele yi-resin. Kubaluleke kakhulu ukuqinisekisa ukuthi ungqimba lokuqala lwezinto zokuqinisa lufakwe ngokuphelele nge-resin futhi lufakwe eduze, ikakhulukazi eminye imikhiqizo okufanele isetshenziswe ezimweni zokushisa eziphakeme. Ukungangenisi kahle kanye ne-lamination engalungile kungashiya umoya ozungeze ungqimba lwe-gelcoat, futhi lo moya oshiywe ngemuva ungabangela amabhamuza omoya ngesikhathi senqubo yokuphulukisa nokusetshenziswa komkhiqizo ngenxa yokwanda okushisayo.
I-Hand Lay-up System, okokuqala kungqimba lwejazi lejeli noma isikhunta esakhiwe phezulu ngebhulashi, i-scraper noma i-impregnation roller kanye nelinye ithuluzi lokunamathisela ngesandla elihlanganiswe ngokulinganayo ngongqimba lwe-resin elungiselelwe, bese ubeka ungqimba lwezinto eziqinisiwe ezisikiwe (njengemicu ediagonal, indwangu emincane noma indawo ezwakalayo, njll.), kulandelwa ukwenza amathuluzi ayisicaba, acindezelwe ukuze avale, acindezelwe ukuze agxilise ukunakwa, ukunakwa ukuze kukhishwe ukunakwa, ukufakwa kwe-brashi Amabhamuza omoya, ukuze indwangu yengilazi ifakwe ngokugcwele, hhayi izingqimba ezimbili noma ngaphezulu zezinto eziqinisayo ngesikhathi esisodwa Ukubeka. Phinda ukusebenza okungenhla, kuze kube ubukhulu obudingekayo ngomklamo.
Uma i-geometry yomkhiqizo iyinkimbinkimbi kakhulu, ezinye izindawo lapho izinto zokuqinisa zingabekwa phansi, ama-bubbles akulula ukuwakhipha, isikelo singasetshenziswa ukusika indawo futhi siyenze ibe flat, kufanele kuqashelwe ukuthi ungqimba ngalunye kufanele lube izingxenye ezinyakazayo zokusika, ukuze zingabangeli ukulahlekelwa amandla.
Izingxenye ezine-engeli ethile, zingagcwaliswaingilazi fiber kanye ne-resin. Uma ezinye izingxenye zomkhiqizo zizinkulu uma kuqhathaniswa, zingaqiniswa ngokufanelekile noma ziqiniswe endaweni ukuze kuhlangatshezwane nezidingo zokusetshenziswa.
Njengoba isiqondiso se-fiber yendwangu sihlukile, amandla ayo nawo ahlukile. Indlela yokubeka i-ingilazi fiber indwanguesetshenziswa kanye nendlela yokubeka kufanele yenziwe ngokwezidingo zenqubo.
(4) ukucutshungulwa komthungo emathangeni
Ungqimba olufanayo lwemicu ngokuqhubekayo ngangokunokwenzeka, gwema ukusikwa ngokungafanele noma ukuhlukaniswa, kodwa ngenxa yobukhulu bomkhiqizo, ubunkimbinkimbi nezinye izizathu zokulinganiselwa okufanele kufinyelelwe, uhlelo lokunamathisela lungathathwa lapho kubekwa i-butt, i-lap seam izonyakaziswa kuze kube yilapho unamathisele ekugqineni okudingekayo umkhiqizo. Uma i-gluing, i-resin ifakwe amathuluzi afana namabhulashi, ama-roller nama-bubble rollers futhi ama-bubbles omoya ayakhishwa.
Uma isidingo samandla siphezulu, ukuze kuqinisekiswe amandla omkhiqizo, i-lap joint kufanele isetshenziswe phakathi kwezicucu ezimbili zendwangu, ububanzi be-lap joint cishe ngama-50 mm. ngesikhathi esifanayo, i-lap joint of layer ngayinye kufanele inyakaze ngangokunokwenzeka.
(3)Ukubeka izandlakweumucu oqoshiwe umatas
Uma usebenzisa i-short cut ezwakala njengezinto eziqinisayo, kungcono ukusebenzisa amasayizi ahlukene we-imregnation rollers ukuze usebenze, ngoba ama-roller okufakwayo asebenza kahle kakhulu ekungabandakanyi ama-bubbles ku-resin. Uma lingekho ithuluzi elinjalo futhi ukufakelwa kufanele kwenziwe ngebhulashi, i-resin kufanele isetshenziswe ngendlela yebhulashi lephoyinti, ngaphandle kwalokho imicu izongcoliswa futhi ikhishwe ukuze ukusabalalisa kungafani futhi ukushuba akufani. Izinto eziqinisayo ezibekwe ekhoneni elijulile langaphakathi ngaphandle, uma ibhulashi noma i-roller impregnation kunzima ukuyenza ilingane eduze, ingalungiswa futhi icindezelwe ngesandla.
Lapho unikeza i-lay-up, sebenzisa i-glue roller ukuze usebenzise i-glue ebusweni besikhunta, bese ubeka i-mat cut. ucezu phezu kwesikhunta futhi ubushelelezi, bese usebenzisa i-glue roller ku-glue, ugoqa ngokuphindaphindiwe emuva naphambili, ukuze i-resin glue igxiliswe ku-mat, bese usebenzisa i-glue bubble roller ukuze ukhiphe i-glue ngaphakathi kwe-mat ebusweni futhi ukhiphe ama-bubbles emoyeni, bese unamathisela ungqimba lwesibili. Uma uhlangana nekhona, ungaklebhula umata ngesandla ukuze kube lula ukusonga, kanti ithanga phakathi kwezingcezu ezimbili zamata lingaba ngu-50mm.
Imikhiqizo eminingi ingabuye isetshenzisweamacansi ama-strand aqoshiwefuthi ingilazi fibre indwangu indwangu alternate layering, ezifana izinkampani Japanese unamathisele isikebhe sokudoba ukusetshenziswa enye indlela yokunamathisela, kubikwa ukuthi indlela yokukhiqiza imikhiqizo FRP ngokusebenza kahle.
(6) Uhlelo lokunamathisela lwemikhiqizo enezindonga eziwugqinsi
Ubukhulu bomkhiqizo obungaphansi kuka-8 mm imikhiqizo ingakhiwa kanye, futhi lapho ubukhulu bomkhiqizo bukhulu kune-8 mm, kufanele ihlukaniswe ngokubumba okuningi, ngaphandle kwalokho umkhiqizo uzophulukiswa ngenxa yokungabibikho kokushisa okuholela ekushiseni, ukuguquguquka, okuthinta ukusebenza komkhiqizo. Emikhiqizweni enokubunjwa okuningi, amabhamu namabhamuza akhiwe ngemva kokwelapha kokuqala okunamathiselwe kufanele kususwe ngefosholo ngaphambi kokuqhubeka nokunamathisela i-pavement elandelayo. Ngokuvamile, kunconywa ukuthi ukujiya kokubumba okukodwa akumele kudlule u-5mm, kodwa futhi kukhona ukukhululwa kokushisa okuphansi kanye nezinsalela ezinciphayo ezithuthukisiwe zokubumba imikhiqizo ewugqinsi, futhi ukujiya kwale resin kukhudlwana ekubumbeni okukodwa.
