Danho reRTM rine zvakanakira hupfumi hwakanaka, dhizaini yakanaka, yakaderera volatlization ye styrene, yakakwira dimensional kurongeka kwechigadzirwa uye yakanaka mamiriro kumusoro kusvika kune giredhi.
RTM inoumbwa maitiro inoda saizi yakakwana yekuumbwa. RTM inowanzo shandisa yin uye yang kuti uvhara iyo mold, saka kukanganisa kwehukuru hwechiumbwa uye chaicho kudzora kweiyo tsictick tisi mushure mekuvhara iyo fold inyaya yakakosha.
1, kusarudzwa kwezvinhu
Kudzora chaiyo yekuumbwa, kusarudzwa kwezvinhu zvishandiso chinhu chakakosha. Kugadzirwa kweRtm moldInoshandiswa muMold Gel jasi rinofanira kuve nekukwira zvakanyanya, kupisa kupisa uye kuderera kuderera, kazhinji kunogona kushandiswa vinyl ester mhando kuumbwa gel jira.
RTM MOLD Resin kazhinji inodawo kurwisa kwakanaka uye kuomarara, kudhakwa kwechidimbu Na 300g / m non-Alkali pfupi-yakatemwa-cuka yakadarika 450g / m non-alkali pfupi-yakatemwa inonzwa yakagadzirwa neyold shrinkage yakadzika, yakakwira dudziro yakadzika, yakakwira dhiziri.
2, process kutonga
Iko kusarudzwa kwezvinhu zvishandiso zvekudzora saizi yertm mold uye cavity gobvu yechibatanidza chinongedzo, uye mune yekuumbwa kushandurudza pakaitika chero nguva yekudzora chinhu chakakosha. Kana ichi chiitiko chekudzora chisina kukodzera, kunyangwe kana zvinhu zvakabiwa zvichisangana nezvinodiwa, zvakaoma kutendeuka kuumbwa nehurongwa hwakakwana uye hwakakwanira cavity ukobvu.
MOLD kutendeuka maitiro anofanira kutanga wanzwisisa kuongororwa kwehuni huni hwekuchinja. Kuti ave nechokwadi chekunyatsoziva, mukutanga kweiyo firita dhizaini yehuni inogona kushandiswa zvichienderana neyakaderera shringer rate kuti usiye huwandu hwehuwandu hwekuvanzika Mukuwedzera, kutariswa kunofanirwa kubhadharwa kuchinjika kwemukati kwehuni hwekugadzira kwehuni kugadziriswa, huni dzepasi pevhu dzinofanira kudzurwa. Mavanga uye Wood Shrinkage haina kuwirirana inokonzeresa pamusoro peiyo fiberglass mold haina flat. Chera mavanga abvise pamusoro pepamhepo burrs, pamusoro pehuni yehuni inofanirwa kunge yakakwenenzverwa kurapwa, kazhinji inodikanwa kuyerera 2 ~ 3 times. Mushure mekunge iyo putty ichirapwa, shandisa sandipaper yekupukuta iyo mamiriro kusvika kwayo yakazara saizi uye kugadzirisa zvakanyatsojeka.
Dhizaini yemifananidzo inofanirwa kuve nechido chekushandisa kushanda nesimba, nekuti kazhinji, kurongeka kwakazara kweFrp Mold pakupedzisirazvinoenderana nekurongeka kwehuni yemapuranga. Kuti ave nechokwadi chekuti pamusoro pegirazi fiber yakasimbiswa epurasitiki mold uye yakachena, tendeuka chidimbu chegirazi yakasimbiswa purasitiki, Gel Coat layer ichishandisa nzira yekupfira yakakodzera.
Spray gelcoat inofanira kutarisisa yekugadzirisa mhepo kuyerera kwepfuti, kuitira kuti gelcoat resin atomu yunifomu, hairatidze zvimedu. Spray Pfuti uye pfuti inofanira kunge iri kunze kweumbi, kuti usakonzera kukonzeresa yemunharaunda jasi renji rakarembera, richikanganisa hunhu. Mushure mekunge iyo Gel Coat layer ichirapwa, pasita nzvimbo yakanzwika. Surpaenzwi rakanzwika rinofanira kunge riri kunze kweiyo mold, kuti usakonzeresa gelcoat yemunharaunda, inokanganisa hunhu.
Pashure pokunge Gel Coat Layer Lued, pasita nzvimbo yakanzwika, iyo nzvimbo yakanzwika inofanira kuvharwa nefurati, yakapetwa kana kubhadharwa kana kutemwa uye kutemwa. Namatai yakanaka nzvimbo yakanzwika, burashi inogona kunyudzwa muhuwandu hwechiratidziro kusvika mukati menzvimbo yakanzwa, teerera kutongwa kwehuwandu hweglue, zvese kuti zviitwe zvizere fiber, asi kwete zvakawandisa. Yakakwira glue yezvinyorwa, bubble haisi nyore kusabvisa, uye kukonzera kuporesa exotermic yakakura, yakakura shrinkage. Surchenzwi yakanzwika layer resin yekurapa kuti vatore mabhuruku, sarudza mabhurugi haigone kucheka kuburikidza neganda reganda.
Mushure mekutora mabhuru, sanding Namatira kune ukobvu rinodiwa, unogona kuisa pombi yemhangura, uye kuisa insipulation core block. Kujairana kwegirazi beads resin
Mushure mekurara, girazi Bead Insulation Core Block Layer Kurapa uye wobva waisa 3 ~ mateya emapfumbamwe emakara-akatemwa, iwe unogona kuseta mold simbi skeleton. Namatira Steel Skeleton, Steel Skeleton yakatanga kuwedzerwa kuti abvise kushushikana, uye sjeleton uye musimbe pakati pechiumbwa chinofanira kuzadzwaFrpkuumbwa kwechigadzirwa neiyo simbi skeleton.
Mushure mekunge chidimbu chekutanga chakaporeswa, chiumbwa chinobviswa, iyo yakawandisa yekubhururuka inobviswa, iyo mold cavity inocheneswa marara, uye pepa ra wax rinoshandiswa. Iko ukobvu hweseti ye wax inoshandiswa kunofanirwa kunge iri yunifomu uye eongation inofanira kunge iri diki. Iro reWax harina kuputirwa mumhepo mabhuru, kana paine mhepo mabhuru, inofanira kubviswa uye zvakare yakadzoreredzwa kuti ive saizi yeiyo mold yemukati. MaJogs majoini anofanirwa kutemwa, uye mapundu pakati paWax mashizha anofanira kuvhenekwa neyekuputika kana yerabhi simende. Mushure mekunge pepa reWax rinoshandiswa, yechipiri mold inogona kushandurwa nenzira imwecheteyo seyekutanga kuumbwa. Chimiro chechipiri chinowanzogadzirwa mushure mekunge Gelcoat yakamiswa, uye maburi jekiseni uye maburi ekuputika anofanirwa kurongwa. Vhura chidimbu chechipiri cheMold, iwe unofanirwa kutanga wabvisa iyo inobhururuka mupendero, weld the pinminging pini uye kuvhara mabheti, kuti uririrwe zvakakwana mushure mekudengenyeka.
3, kuumbwa kuongororwa uye kugadzirisa matanho
Mushure mekudengenyeka uye kuchenesa, shandisa simbheri yeriment kuyera ukobvu hwechiumbwa. Kana ukobvu uye saizi inogona kusangana nezvinodiwa, mushure mekugeza uye mushure mekukuya uye kupukuta pikicha, iyo RTM inoumbwa ichashandurwa zvakabudirira uye inogona kuendeswa kugadzirwa. Kana iyo bvunzo, nekuda kwekutonga kwemarombo kuita uye zvimwe zvikonzero zvinokonzerwa neyekuumbwa kwechiumbwa hachina kuita zvinodiwa, kupururudza, kuvhura mold kwakawanda kwazvo.
Sekureva ruzivo panogona kuve nemishonga miviri:
① yakakwenenzverwa imwe yemumbara, bvisa zvakare chidimbu;
② Kushandiswa kweiyo rtm maitiro pachayo kuti agadzirise hunhu hwechiumbwa, kazhinji chidimbu cheMold Surven Gelcoat layergirazi fiber rakasimbiswa zvinhu, chimwe chidimbu cheMold chakanangana neiyo wax pepa, pfira gelcoat, uye ipapo iyo mold jekiseni, kuti iporese mushure mekugadzirwa kwekuumbwa, kunogona kuendeswa kushandiswa.
