RTM maitiro ane mabhenefiti ehupfumi hwakanaka, dhizaini yakanaka, yakaderera volatilization ye styrene, yakakwira dimensional kurongeka kwechigadzirwa uye yakanaka yepamusoro yepamusoro kusvika kugiredhi A pamusoro.
RTM molding process inoda yakawedzera saizi ye mold. rtm inowanzo shandisa yin uye yang kuvhara mold, saka saizi yekukanganisa kwe mold uye kunyatso kudzora kwegomarara remukati mushure mekuvhara mold inyaya yakakosha.

1, Kusarudzwa kwezvinhu
Kudzora kurongeka kwe mold, kusarudzwa kwezvinhu zvakasvibirira chinhu chakakosha. Kugadzirwa kweRTM moldrinoshandiswa mu mold gel jasi rinofanirwa kuve nehupamhi hwekuomarara, kukwirira kupisa kupisa uye kuderera kuderera, kazhinji inogona kushandiswa vinyl ester mhando mold gel jasi.
RTM mold resin inowanzodawo kunaka kwekupisa uye kusimba, imwe dhigirii yekukanganisa kusimba, shrinkage idiki kana pedyo ne zero shrinkage.RTM molds ine fiber reinforcement materials inogona kushandiswa 30g / ㎡ isiri-alkali pamusoro inonzwa uye 300g / ㎡ isiri-alkali pfupi-yakatemwa-yakanzwika. Iine 300g / m isiri-alkali pfupi-yakatemwa yakanzwa kupfuura 450g / m isiri-alkali pfupi-yakatemwa yakanzwa yakagadzirwa neforoma shrinkage yakaderera, yakakwira dimensional kunyatsoita.

2, Kudzora maitiro
Kusarudzwa kwezvinhu zvakasvibirira ndezvekudzora saizi yeRTM mold uye ukobvu hwemhango yechinhu chakakosha chinongedzo, uye mukugadzira mold kutendeuka chero nguva kutonga kwemhando ndiyo inonyanya kukosha maitiro. Kana iyi nzira yekudzora isina kufanira, kunyangwe iyo mbishi zvinhu inosangana nekushandiswa kwezvinodiwa, zvakaoma kushandura mold ine zviyero zvakaringana uye kukwenenzvera mhango ukobvu.
Mold inoshandura nzira inofanira kutanga yabata kurongeka kweshanduko yehuni mold. Kuti uve nechokwadi chechokwadi, mukutanga kwesefa huni mold dhizaini inogona kushandiswa zvinoenderana neiyo mold shrinkage rate kusiya imwe chiyero che shrinkage allowance. Uye zvakare, kutarisisa kunofanirwa kubhadharwa kune shanduko yepasi pehuni mold kugadzirisa flat, huni mold surface scarring inofanira kucherwa kunze. Mavanga uye shrinkage yehuni haina kuenderana zvinokonzeresa kuti pamusoro pefiberglass mold haina kufuratira. Chera mavanga uye bvisa mabhura epamusoro, pamusoro pehuni mold inofanirwa kukweshwa putty kurapwa, kazhinji inodiwa kukwenya 2 ~ 3 nguva. Mushure mekunge putty yaporeswa, shandisa sandpaper kupukuta pamusoro kusvika yanyatsozadzisa saizi uye chimiro chechokwadi zvinodiwa.
Kugadzirwa kwehuni mold kunofanirwa kuve nechido chekushandisa simba, nekuti kazhinji, iyo dimensional kurongeka kweFRP mold pakupedzisirazvinoenderana nekururama kwehuni yehuni. Kuti uve nechokwadi chekuti pamusoro pegirazi faibha yakasimbiswa mold yepurasitiki yakatsetseka uye yakachena, shandura chidimbu chekutanga chegirazi faibha yakasimbisa epurasitiki mold, gel jasi layer uchishandisa nzira yekupfapfaidza inonyanya kukodzera.
Kupfapfaidza gelcoat kunofanirwa kutarisisa kugadzirisa kuyerera kwemhepo yepfuti, kuitira kuti gelcoat resin atomization ive yunifomu, isingaratidzi zvidimbu. Pfuti yekupfapfaidza uye pfuti inofanira kunge iri kunze kwe mold, kuitira kuti irege kukonzera gel jasi remunharaunda rakarembera, richikanganisa kunaka kwepamusoro. Mushure mokunge gel jasi rejasi raporeswa, isa pasi rinonzwa. Surface inonzwa inofanirwa kunge iri kunze kwe mold, kuitira kuti isakonzerese gelcoat yemuno kurembera, ichikanganisa kunaka kwepamusoro.
Mushure mekunge gel jasi rejasi raporeswa, namatidza iyo nzvimbo inonzwa, iyo nzvimbo inonzwa inofanirwa kuvharwa neyakatsetseka, yakapetwa kana pamakumbo inofanira kutemwa uye kuchekwa. Namatira nzvimbo yakanaka inonzwa, bhurasho rinogona kunyikwa mune diki resin kunyura kuburikidza nepamusoro yakanzwa, teerera kune kutonga kwehuwandu hweglue, zvese kuti zvikwanise kupinza zvizere fiber, asi kwete zvakanyanya. Yakakwira glue zvemukati, iyo bubble haisi nyore kusabvisa, uye inokonzeresa kurapa exothermic yakakura, yakakura shrinkage. Surface yakanzwa layer resin kurapa kutora mabubbles, nhonga mabhuru haagone kucheka nepakati peiyo gel jasi layer.
Mushure mekunhonga mabubble, sanding yakakodzera, bvisa mafiberglass burrs uye bvisa guruva rinoyangarara, ruoko-namira 300g / m² isiri-alkali pfupi-yakatemwa inonzwa, nguva yega yega 1 ~ 2 zvidimbu zvenamira, kuti zvirapwe mushure meiyo exothermic peak usati waenderera mberi nekunamira. Namira kune ukobvu hunodiwa, unogona kuisa pombi yemhangura, uye kuisa insulation core block. Modulation yegirazi beads resin putty, sekuiswa kwe thermal insulation core block adhesive, iyo yekuzadza gaka pakati peiyo thermal insulation core block.
Mushure mekuisa, girazi bead putty rinofanira kushandiswa kutsvedzerera gaka riri pamusoro peiyo insulation core block. Insulation core block layer kurapa uye wozoisa 3 ~ 4 akaturikidzana epfupi-akacheka akanzwa, unogona kunamira mold simbi skeleton. Namatidza simbi skeleton, simbi skeleton inotanga kunyungudutswa kuti ibvise kushushikana kwewelding, uye simbi skeleton uye mukaha pakati peforoma unofanirwa kuzadzwa kudzivirira iyo.FRPmold deformation nesimbi skeleton.
Mushure mokunge chidimbu chekutanga chehutu chaporeswa, mold inobviswa, iyo yakawandisa inobhururuka inobviswa, gomba rekuumbwa rinocheneswa kubva kumarara, uye pepa rewakisi rinoiswa. Ukobvu hwebepa rewakisi rinoshandiswa hunofanirwa kunge hwakafanana uye kureba kunofanira kuita kudiki. Pepa rewakisi harifanirwe kuputirwa mumapupu emhepo, kana paita mabhuru emhepo, rinofanirwa kubviswa ronamirwa patsva kuti pave nekukura kwegomba. Majoini epamakumbo anofanira kuchekwa, uye mikaha pakati pewakisi inofanira kuenzaniswa neputty kana simende yerabha. Mushure mekunge bepa rewakisi raiswa, mold yechipiri inogona kushandurwa nenzira yakafanana neyekutanga. Yechipiri mold inowanzogadzirwa mushure mekunge gelcoat yapfapfaidzwa, uye maburi ejekiseni uye maburi emhepo anofanirwa kurongwa. Tendeuka chechipiri chimedu chekuumbwa, iwe unofanirwa kutanga wabvisa kumucheto kunobhururuka, weld mapini ekumisikidza uye kuvhara mabhaudhi, kuti unyatsopora mushure mekudhirowa.

3, Mold kuongorora uye kugadzirisa matanho
Mushure mekudhirowa nekuchenesa, shandisa simende yerabha kuyera ukobvu hwegomba re mold. Kana ukobvu uye saizi zvichigona kuzadzisa zvinodiwa, ipapo mushure mekukuya uye kukwenenzverwa maitiro kwapera, iyo RTM mold inoshandurwa zvinobudirira uye inogona kuendeswa kune kugadzirwa. Kana bvunzo, nekuda kwehurombo hurongwa kutonga uye zvimwe zvikonzero zvinokonzerwa negomba mhango haaite zvinodiwa, zvimedu, vhurazve mold yakanyanyisa tsitsi.
Maererano neruzivo, zvinogona kuva nemishonga miviri:
① akakwenya imwe mold, vhurazve chidimbu;
② kushandiswa kweRTM maitiro ega kugadzirisa hunhu hwe mold, kazhinji chidimbu cheiyo mold surface gelcoat layer yakabviswa, yakaradzikwa pamusoro.girazi fiber reinforced material, chimwe chimedu che mold chinonamirwa kune wax sheet, pfapfaidza gelcoat, uye ipapo jekiseni reforoma, rinoporeswa mushure mekugadzira mold, rinogona kuendeswa kushandiswa.
