Zvakanakira nekuipira kwezviviri izvi zvinofananidzwa sezvinotevera:
Kuisa ruoko-up inzira yakavhurika-mold iyo parizvino inotora 65% yegirazi fiberyakasimbiswa polyester composites. Zvayakanakira ndezvekuti ine hukuru hukuru hwerusununguko mukuchinja chimiro cheforoma, mutengo wekuumbwa wakaderera, kuchinjika kwakasimba, kuita kwechigadzirwa kunozivikanwa nemusika, uye mari yakaderera. Saka inonyanya kukodzera kumakambani maduku, asiwo kune mabhizimisi emugungwa uye aerospace, uko inowanzova chikamu chikuru chimwe chete. Zvisinei, panewo nhevedzano yezvinetso mukuita uku. Kana iyo volatile organic compound (VOC) emission ikadarika mwero, ine simba guru pahutano hwevashandisi, zviri nyore kurasikirwa nevashandi, pane zvakawanda zvinorambidzwa pazvinhu zvinotenderwa, kuita kwechigadzirwa kwakadzikira, uye resin inoraswa. uye inoshandiswa muhuwandu hukuru, kunyanya chigadzirwa. Hunhu hwacho hauna kugadzikana. Chikamu chegirazi fiber uye resin, kukora kwezvikamu, chiyero chekugadzirwa kwechigadziko, uye kufanana kwechigadziko zvose zvinokanganiswa nemushandi, uye mufambisi anodiwa kuti ave nekombiyuta iri nani, ruzivo uye unhu.The resinZviri mukati mezvigadzirwa zvekuisa-maoko zvinowanzotenderedza 50% -70%. Iyo VOC kuburitswa kweiyo mold yekuvhura process inodarika 500PPm, uye volatilization ye styrene yakakwira se35% -45% yehuwandu hunoshandiswa. Mitemo yenyika dzakasiyana ndeye 50-100PPm. Parizvino, nyika zhinji dzekunze dzinoshandisa cyclopentadiene (DCPD) kana imwe yakaderera styrene kuburitsa resin, asi hapana chakanaka chinotsiva styrene semonomeri.
Fiberglass mat ruoko kuisa-up process
Iyo vacuum resinnhanganyaya inzira yakaderera yekugadzira yakagadzirwa mumakore makumi maviri apfuura, kunyanya yakakodzera kugadzirwa kwezvinhu zvakakura. Zvayakanakira ndezvizvi:
(1) Chigadzirwa chine kuita kwakanakisa uye goho repamusoro.Panyaya yakafananafiberglassmbishi, simba, kuomarara uye zvimwe zvinhu zvemuviri zvevacuum resin-yakaunzwa zvikamu zvinogona kuvandudzwa neinopfuura 30% -50% zvichienzaniswa nemaoko ekuisa-up zvikamu (Table 1). Mushure mokunge nzira yacho yakagadzikana, goho rinogona kuva pedyo ne100%.

(2) Hunhu hwechigadzirwa hwakagadzikana uye kudzokorora kwakanaka.Chigadzirwa chemhando hachinyanyi kukanganiswa nevashandisi, uye kune yakakwira dhigirii yekuenderana ingave iri chikamu chimwe chete kana pakati pezvikamu. Iyo fiber yemukati yechigadzirwa yakaiswa muforoma zvinoenderana nehuwandu hwakatarwa resin isati yaiswa jekiseni, uye zvikamu zvacho zvine chiyero chisingachinji resin, kazhinji 30% -45%, saka kufanana uye kudzokorora kwekuita kwechigadzirwa kuri. zviri nani pane zvigadzirwa zvekuisa ruoko. zvakawanda, uye zvishoma zvirema.
(3) Iyo anti-kuneta kuita inovandudzwa, iyo inogona kuderedza uremu hwechimiro.Nekuda kweiyo yakakwira fiber, yakaderera porosity uye yakakwira chigadzirwa, kunyanya kuvandudzwa kwe interlaminar simba, kuneta kuramba kwechigadzirwa kunovandudzwa zvakanyanya. Panyaya yesimba rakafanana kana kuomarara zvinodiwa, zvigadzirwa zvinogadzirwa neiyo vacuum induction process zvinogona kuderedza huremu hwechimiro.
(4) Kushamwaridzana nemhoteredzo.Iyo vacuum resin infusion process ndeye yakavharwa mold process apo inovhurika organics uye muchetura zvinosvibisa mweya zvinovharirwa mubhegi rekutsvaira. Chete kuteedzera huwandu hwekuvhuvhuta huripo kana pombi yevacuum ichiburitswa (inosefa) uye resin barrel yakavhurwa. VOC emissions haipfuure mwero we5PPm. Izvi zvakare zvinovandudza zvakanyanya nharaunda yekushanda yevashandisi, inodzikamisa vashandi, uye inowedzera huwandu hwezvinhu zviripo.
(5) Kutendeseka kwechigadzirwa kwakanaka.Iyo vacuum resin sumo yekuita inogona kuumba inosimbisa mbabvu, sandwich zvimiro uye zvimwe zvinoiswa panguva imwe chete, izvo zvinovandudza kuvimbika kwechigadzirwa, saka zvigadzirwa zvakakura senge fan hoods, ngarava dzechikepe uye superstructures inogona kugadzirwa.
(6) Deredza kushandiswa kwezvinhu zvakabikwa uye kushanda.Mukurongeka kwakafanana, huwandu hweresin hunoderedzwa ne30%. Kurasa kushoma, resin kurasikirwa mwero iri pasi pe5%. Kubudirira kwepamusoro kwevashandi, kudarika 50% kuchengetedza kwevashandi zvichienzaniswa nemaitiro ekuisa maoko. Kunyanya mukuumbwa kweakakura uye akaoma geometries esangweji uye yakasimbiswa zvimiro zvikamu, izvo zvekushandisa uye kuchengetedza kwevashandi zvinotonyanya kukosha. Semuyenzaniso, mukugadzira vertical rudders muindasitiri yendege, mutengo wekudzikisa fasteners ne365 inoderedzwa ne75% kana ichienzaniswa neyechinyakare nzira, huremu hwechigadzirwa hunoramba husingachinji, uye kuita kuri nani.
(7) Chigadzirwa chacho chakanaka.Kurongeka kwedimensional (hukobvu) hwevacuum resin sumo yekuita zvigadzirwa zviri nani pane izvo zvekugadzira-maoko zvigadzirwa. Pasi peyakafanana, kukora kweyakajairwa vacuum resin diffusion tekinoroji zvigadzirwa ndeye 2/3 yeiyo yezvigadzirwa zvekuisa-maoko. Iko kutsauka kwechigadzirwa kunenge ± 10%, nepo kugadzika kwemaoko maitiro kunowanzo ± 20%. Kupfava kwechigadzirwa chacho kuri nani pane kwezvigadzirwa zvekuisa maoko. Rusvingo rwemukati rwechigadzirwa chehodhi yevacuum resin introduction process inotsvedzerera, uye pamusoro pechisikigo inoumba resin-rich layer, iyo isingade yakawedzera jasi repamusoro. Yakaderedzwa basa uye zvinhu zvekugadzira jecha nekupenda maitiro.
Ehe, iyo yazvino vacuum resin sumo maitiro zvakare ine zvimwe zvikanganiso:
(1) Nzira yekugadzirira inotora nguva yakareba uye yakaoma zvikuru.Kurongeka kwakaringana, kuiswa kwe diversion media, diversion tubes, inoshanda vacuum sealing, nezvimwe zvinodikanwa. Naizvozvo, kune zvigadzirwa zvidiki-diki, iyo nzira yenguva yakareba kupfuura yekuisa ruoko-up process.
(2) Mutengo wekugadzira wakakwira uye tsvina yakawanda inogadzirwa.Zvishandiso zvekubatsira senge vacuum bag firimu, diversion medium, jira rekuburitsa uye diversion chubhu zvese zvinoraswa, uye zvakawanda zvacho zviri kutengwa kunze kwenyika, saka mutengo wekugadzira wakakwira kupfuura nzira yekuisa ruoko. Asi iyo yakakura chigadzirwa, iyo idiki mutsauko. Nekumisikidzwa kwezvinhu zvekubatsira, mutsauko wemutengo uyu uri kuita udiki uye udiki. Tsvagiridzo yazvino pazvinhu zvekubatsira zvinogona kushandiswa kakawanda inzira yekusimudzira yeiyi maitiro.
(3) Kugadzira nzira kune dzimwe njodzi.Kunyanya kune zvakakura uye zvakaoma zvigadziriso zvigadzirwa, kana iyo resin infusion yatadza, chigadzirwa chiri nyore kuraswa.
Naizvozvo, zvirinani tsvakiridzo yekutanga, yakasimba maitiro ekudzora uye anobudirira ekugadzirisa matanho anodiwa kuti ive nechokwadi chekubudirira kwemaitiro.
Zvigadzirwa zvekambani yedu:
Fiberglass roving, fiberglassrakarukwa roving, fiberglass mats, fiberglass mesh jira,unsaturated polyester resin, vinyl ester resin, epoxy resin, gel coat resin, anobatsira FRP, kabhoni faibha uye zvimwe mbishi zvinhu zveFRP.
