(6) Ukulungiswa kwezinqubo zenqubo yokubumba.
4. Uhlelo lokunamathisela ungqimba lwepulasitiki oluqiniswe nge-fiber yengilazi
Ukubeka isandla kuyinqubo ebalulekile yenqubo yokunamathisela yokunamathisela ngesandla, kufanele kube ukusebenza kahle ukuze kuzuzwe okuqukethwe kwe-resin okusheshayo, okunembile, okufana, akukho amagwebu asobala, akukho impregnation empofu, akukho monakalo ku-fiber kanye nomkhiqizo osezingeni eliphezulu, ukuqinisekisa ikhwalithi. kwemikhiqizo. 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, idizayini yenqubo yokunamathisela ngesandla kanye nenqubo yokukhiqiza izohlangabezana nezinkinga zobuchwepheshe, lapho sazi ubukhulu obudingekayo bomkhiqizo, kuyadingeka ukubala ukuthola 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 nokunquma iphesenti lokuqukethwe kwe-glass fiber mass.
(3)Ingilazii-fiberuhlelo lokunamathisela indwangu
Imikhiqizo ene-gelcoat layer, i-gelcoat ayikwazi ukuxubana nokungcola, unamathisele ngaphambi kwesistimu kufanele ivimbele 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.
Isistimu yokubeka izandla, okokuqala kungqimba lwejazi lejeli noma indawo yokwenza isikhunta ngebhulashi, i-scraper noma i-impregnation roller kanye nelinye ithuluzi lokunamathisela ngesandla elimbozwe ungqimba lwe-resin elungisiwe, bese ubeka ungqimba lwezinto zokuqinisa ezisikiwe (njengokuthi amapheshana diagonal, indwangu elincanyana noma surface bazizwa, njll.), kulandelwa ukwakha amathuluzi uzobe brushed flat, sicindezelwe, ukuze kufanelana eduze, futhi unake ukukhishwa amabhamuza emoyeni, ukuze indwangu ingilazi lifakwe ngokugcwele, hhayi ezimbili. noma izingqimba eziningi zezinto eziqinisayo ngesikhathi esisodwa Ukubeka. Phinda ukusebenza okungenhla, kuze kube ukushuba okudingekayo umklamo.
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 kube izingxenye ezinyakazayo zokusikwa, 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 kufanele. zinyakaze kuze kube unamathisele kuze kube ukujiya 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 the 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 iglue ye-resin icwiliswe kumata, bese usebenzisa i-glue bubble roller ukuze ukhiphe ingcina ngaphakathi kwe-mat. phezulu bese ukhipha 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 kuno-8 mm, kufanele ihlukaniswe ngokubumba okuningi, ngaphandle kwalokho umkhiqizo uzophulukiswa ngenxa yokungabibikho kokushisa okuholela ekushiseni, ekushintsheni kombala, 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.
