Zvakanakira nezvakaipa zveizvi zviviri zvinoenzaniswa seizvi:
Kuisa maoko mudenga inzira yakavhurika iyo parizvino inoita 65% yegirazi faibhama polyester composites akasimbiswa. Zvakanakira zvayo ndezvekuti ine rusununguko rwakakura mukuchinja chimiro chemold, mutengo wemold wakaderera, kugona kwayo kuchinjika kwakasimba, mashandiro echigadzirwa anoonekwa nemusika, uye mari inodyarwa yakaderera. Saka yakakodzera makambani madiki, asiwo kumaindasitiri emugungwa nendege, uko kazhinji kacho chikamu chikuru. Zvisinei, kunewo matambudziko akatevedzana mukuita uku. Kana kubudiswa kwemhepo inoputika (VOC) kukadarika mwero, kune simba guru pahutano hwevashandi, zviri nyore kurasikirwa nevashandi, kune zvirambidzo zvakawanda pazvinhu zvinobvumidzwa, mashandiro echigadzirwa akaderera, uye resin inoraswa uye inoshandiswa zvakanyanya, kunyanya chigadzirwa. Hunhu hwayo hahuna kugadzikana. Chikamu chegirazi faibha uye resin, ukobvu hwezvikamu, mwero wekugadzirwa kwechikamu, uye kufanana kwechikamu zvese zvinokanganiswa nemushandisi, uye mushandisi anofanirwa kuve netekinoroji iri nani, ruzivo uye mhando.Resinhuwandu hwezvigadzirwa zvemaoko zvinowanzoita 50%-70%. Kuburitswa kweVOC kwemaitiro ekuvhura mold kunodarika 500PPm, uye kuputika kwestyrene kwakakwira kusvika 35%-45% yehuwandu hwakashandiswa. Mitemo yenyika dzakasiyana-siyana ndeye 50-100PPm. Parizvino, nyika zhinji dzekunze dzinoshandisa cyclopentadiene (DCPD) kana mamwe maresini ekuburitsa styrene akaderera, asi hapana chinotsiva styrene semonomer.
Meti yegirazi refiberglass maitiro ekuisa maoko
Resin ye vacuumMaitiro ekutanga inzira yekugadzira inodhura zvishoma yakagadzirwa mumakore makumi maviri apfuura, inonyanya kukodzera kugadzirwa kwezvinhu zvikuru. Zvakanakira zvayo ndeizvi:
(1) Chigadzirwa chacho chine mashandiro akanaka kwazvo uye goho guru.Kana zvakadarofiberglassZvinhu zvakagadziriswa, simba, kuomarara uye zvimwe zvinhu zvemuviri zvezvikamu zvakaunzwa ne vacuum resin zvinogona kuvandudzwa neanopfuura 30%-50% zvichienzaniswa nezvikamu zvakaiswa nemaoko (Tafura 1). Mushure mekunge maitiro acho agadzikana, goho rinogona kusvika pa100%.

(2) Hunhu hwechigadzirwa hwakagadzikana uye kugona kudzokororwa kwakanaka.Hunhu hwechigadzirwa hahunyanyi kukanganiswa nevanoshandisa, uye pane mwero wepamusoro wekuenderana kungave kuri chinhu chimwe chete kana pakati pezvikamu. Hunhu hwefiber hwechigadzirwa hwakaiswa muchiumbwa zvichienderana nehuwandu hwakatarwa usati waisa resin, uye zvikamu zvacho zvine chiyero cheresin chakafanana, kazhinji 30%-45%, saka kufanana uye kudzokorora kwekushanda kwechigadzirwa kuri nani pane zvigadzirwa zvekugadzira nemaoko. Zvine zvakawanda, uye zvikanganiso zvishoma.
(3) Kushanda kwekudzivirira kuneta kunovandudzwa, izvo zvinogona kuderedza huremu hwechivakwa.Nekuda kwehuwandu hwakawanda hwefiber, porosity shoma uye kushanda kwepamusoro kwechigadzirwa, kunyanya kuvandudzwa kwesimba re interlaminar, kuramba kuneta kwechigadzirwa kunovandudzwa zvikuru. Kana paine zvinodiwa zvakafanana zvesimba kana kuomarara, zvigadzirwa zvakagadzirwa ne vacuum induction process zvinogona kuderedza huremu hwechivakwa.
(4) Hazvikuvadzi nharaunda.Maitiro ekupinza vacuum resin inzira yekuvharwa kweforoma umo zvinhu zvinoputika zveorganics uye zvinosvibisa mhepo zvine chepfu zvinongoiswa mubhegi revacuum. Zvishoma chete zvevolatiles zvinovapo kana pombi yevacuum yaburitswa mweya (inosefa) uye bhare re resin ravhurwa. VOC emissions haipfuure mwero we5PPm. Izvi zvinovandudzawo zvikuru nzvimbo yekushandira yevashandi, zvinodzikamisa vashandi, uye zvinowedzera huwandu hwezvinhu zviripo.
(5) Kuvimbika kwechigadzirwa kwakanaka.Maitiro ekupinza vacuum resin anogona kugadzira mbabvu dzinosimbisa, zvivakwa zvesandwich nezvimwe zvinoiswa panguva imwe chete, izvo zvinovandudza kunaka kwechigadzirwa, saka zvigadzirwa zvakakura zvakaita semafeni, zvikepe uye masuperstructure zvinogona kugadzirwa.
(6) Deredza kushandiswa kwezvinhu zvakagadzirwa uye vashandi.Mukugadzirisa kumwe chete, huwandu hweresin hunoderedzwa ne30%. Marara mashoma, kurasikirwa kweresin kuri pasi pe5%. Kubudirira kukuru kwevashandi, kuchengetedza vashandi kunopfuura 50% kana tichienzanisa nemaitiro ekuisa nemaoko. Kunyanya mukuumba majeometri makuru uye akaomarara esandwich nezvikamu zvekuvaka zvakasimbiswa, kuchengetedza zvinhu nevashandi kwakanyanya kukosha. Semuenzaniso, mukugadzira marudders akamira muindasitiri yendege, mutengo wekuderedza zvisungo ne365 unoderedzwa ne75% kana tichienzanisa nenzira yechinyakare, huremu hwechigadzirwa hunoramba hwakachinja, uye mashandiro acho ari nani.
(7) Kunyatsorongeka kwechigadzirwa kwakanaka.Kururama kwehukuru (ukobvu) hwezvigadzirwa zvekugadzira vacuum resin zviri nani pane zvezvigadzirwa zvekugadzira nemaoko. Pasi pehurongwa humwe chete, ukobvu hwezvigadzirwa zvekugadzira vacuum resin zvinopararira hunosvika 2/3 yezvigadzirwa zvekugadzira nemaoko. Kutsauka kwehukuru hwezvigadzirwa kunenge ±10%, nepo maitiro ekugadzira nemaoko anowanzova ±20%. Kusatsetseka kwepamusoro pechigadzirwa kuri nani pane kwezvigadzirwa zvekugadzira nemaoko. Rusvingo rwemukati rwechigadzirwa chehood chegadziriro yekugadzira vacuum resin rakatsetseka, uye pamusoro pacho panoita jira rakapfuma re resin, risingade imwe top coat. Kuderedzwa kwebasa nezvinhu zvekugadzira sanding nekupenda.
Ehe, maitiro ekugadzira vacuum resin pari zvino ane zvimwe zvikanganiso:
(1) Kugadzirira kunotora nguva yakareba uye kwakaoma zvikuru.Kuisa zvinhu zvakanaka, kuisa zvinhu zvinochinja-chinja, machubhu ekuparadzanisa, kuvhara vacuum zvinobudirira, nezvimwewo zvinodiwa. Saka, kune zvigadzirwa zvidiki, nguva yekushanda inopfuura yekuisa zvinhu nemaoko.
(2) Mutengo wekugadzira wakakwira uye marara akawanda anogadzirwa.Zvinhu zvinobatsira zvakaita sefirimu remabhegi evacuum, diversion medium, release cloth uye diversion tube zvese zvinoraswa, uye zvakawanda zvacho zvinotengwa kunze kwenyika parizvino, saka mutengo wekugadzira wakakwira kupfuura maitiro ekuisa nemaoko. Asi kana chigadzirwa chakakura, musiyano wacho mudiki. Nekuwanikwa kwezvinhu zvinobatsira, musiyano uyu wemutengo uri kuramba uchiwedzera kuderera. Tsvagiridzo iripo pari zvino yezvinhu zvinobatsira zvinogona kushandiswa kakawanda inzira yekuvandudza maitiro aya.
(3) Kugadzira maitiro kune njodzi dzakati wandei.Kunyanya kune zvigadzirwa zvakakura uye zvakaoma zvekuvaka, kana resin ikasashanda, chigadzirwa chacho chiri nyore kuraswa.
Saka, tsvakiridzo yekutanga iri nani, kudzora maitiro akaomarara uye matanho ekugadzirisa anoshanda anodiwa kuti kuve nechokwadi chekubudirira kwemaitiro acho.
