3. Kupatsanura mitsara (isina kunamira)
chikonzero:
Kusakwanirisa kupukuta wakisi, silicone-based release agents inowanzova nepakati iri pachena, uye mvura kana mafuta inosanganiswa kana uchimwaya.
Mhinduro:
Mushure mekupukuta wakisi zvakazara, ipukute nekukasika kusvika yapenya, shandisa wakisi kana mold release agent kune zvigadzirwa uye zvigadzirwa, shandisa mhepo yakaoma, uye isa chinoparadzanisa-mvura yemafuta.
4. Muviri wekunze wakasanganiswa
chikonzero:
Zvidiki zvidiki uye miviri yekune dzimwe nyika mujasi regel, tsvina pamusoro pemuumbi, zvipembenene zvinobhururuka mumushonga uye guruva mumusangano wekugadzira.
Mhinduro:
Paunenge uchishandisa iyo yakasefa gel jasi, mold inofanirwa kucheneswa uye kucheneswa isati yapfapfaidza gel jasi, uye iyo static magetsi pamusoro peiyo mold inofanira kubviswa pasi pemamiriro ekudzivirira kupinda kwezvipembenene zvinobhururuka uye chengeta wega wekugadzira musangano.
5. kuunyana
chikonzero:
Ukobvu hweiyo yekutanga layer ye gelcoat kana bhurasho risina kukwana, nguva iri pakati pekukwesha gelcoat (2 times) ipfupi, mold kana gelcoat ine hunyoro panguva yekushandiswa kwegelcoat ichikonzera kushomeka kwepolymerization gelcoat, hunyoro hwepabasa hwakanyanya. kana kusakwana kuomeswa kwePVA kana kuomesera kushoma, kunonoka kupora kwegelcoat, kurapa kusina kuenzana kwegelcoat.
Mhinduro:
Shandisa zvakaenzana kuitira kuti kukora kwefirimu yekutanga kuve 0.2-0.25 mm. Mushure mokunge gelcoat yapora zvakakwana, shandisa gelcoat yechipiri kana topcoat uye shandisa gelcoat mushure mekunge mold yakaoma, dehumidify kana kumisa kushandiswa mumamiriro ezvinhu akaoma. Rega PVA iome zvachose wozoisa gelcoat. Muyero wehardener unofanirwa kuva pakati pe2.5% ne1%. Wedzera tembiricha yebasa uye upe mhepo kuitira kuti pasave ne styrene gasi rinoramba riri mukugadzira mold.
6. kudhirowa
chikonzero:
Mushure mekutsvaira gelcoat, mold ichakanganisa panguva yekubata uye nzvimbo yemunharaunda ichapisa. Huwandu hwegelcoat hardener hwakakurisa, musiyano wetembiricha wakakurisa. Yakanyanya kuburitsa mold coating haina kunaka kuchenesa. Kusara nguva refu mushure mekushandisa gel jasi.
Mhinduro:
Paunenge uchibata, chenjerera kuti usasvibisa mold. Kana inopisa, mold haifaniri kuiswa pamucheto wekupisa, kuitira kuti kusiyana kwekushisa kurege kuchinja zvakanyanya. Mushure mekuwakisisa, buff kusvika kupenya. Kushandisa Release Wax Nzira Yakarurama Mushure mekushandisa gelcoat, inofanira kuiswa mukati memaawa makumi maviri nemana.
7. kupenya kwakaipa
chikonzero:
Iyo mold surface yakasviba, mold surface kupenya haina kusimba, uye mold haina kunyatsogadziriswa.
Mhinduro:
Ita gadziriro yakanaka pane mold, uye mushure meimwe chiyero chekugadzirwa, mold inofanira kucheneswa zvakare. Pese panoda kukwenenzverwa wakisi kusvika yapenya, wakisi yasara inofanira kucheneswa mushure mewakisi, jasi rejeli rinofanira kushandiswa kugadzira mold uye 150# water sandpaper - 2000# inofanira kushandiswa kunyatsokwenenzvera, kukwenenzvera, kuchena. uye zviumbwa zvidhindo. Mold post-processing inoitwa.
8. Mapupu, mabhuru emhepo asina chinhu pakati pejasi regel uye laminate.
chikonzero:
Pakuisa tsvina ye gelcoat yakapinda uye iyo yekumusoro layer haina kunyatso defoam.
Mhinduro:
Chenesa pendi zvishandiso uye molds. Kunyatsobvisa furo pakuisa.
9. ruvara rusina kuenzana
chikonzero:
Unyoro hunosanganiswa mujasi regel, sagging (pigment separation) inoitika, kusaenzana kwebhurashi (hwaro hunogona kuonekwa kuburikidza nejasi rejeri), kusakwana kunokonzera (pigment inonaya mumudziyo). Kusiya nguva refu mushure mekukwenya pendi. Mavara akasanganiswa paunenge uchiwedzera pendi
Solution:
Kuvandudza thixotropy yejasi regel, shandisa zvakafanana (0.3-0. 5 mm), uye fambisa zvakanaka. Paunenge uchishandisa iyo yakawedzera pigment (gel jasi), jasi rejeli mumudziyo rinofanira kuzunguzwa zvizere neglue, uye nzvimbo yebasa inofanira kucheneswa kana uchishandisa jasi rejeri, imba yekuchengetera iyo inoiswa jasi yegel inofanira kunge yakachena uye yakarongeka.
10. Kusapora
chikonzero:
Ndakanganwa kuwedzera accelerator kana kurapa mumiririri, yakawandisa accelerator, kushata kubvongodza, styrene gasi kuchengetedza, uye yakaderera tembiricha.
Solution:
Usati washandisa, simbisa kana iyo accelerator yakawedzerwa. Mushure mekuwedzera mushonga wekurapa, unofanirwa kunyandurwa uye kufefeterwa kuvhuvhuta gasi re styrene rakavharirwa pasi uye kuwedzera tembiricha yenzvimbo yebasa.
11. mavanga
chikonzero:
Makwara, maronda emu wedge, mold release blow kukuvara, mold release agent, wax residu, PVA brush marks, mold mavanga.
Solution:
Shanda nekungwarira, chengetedza chigadzirwa nezvinhu zvakapfava, shandisa muchina wekucheka nemazvo, shandisa nzira yekudhirowa nenzira kwayo, tora mold zvishoma, ita kugadzirisa mold uye kugadzirisa kazhinji, uye isa PVA yakatetepa uye yakaenzana.
12. mutswe
chikonzero:
Kusada kudhirowa, chimiro chisina musoro, kuvhuvhuta (spider web crack), kuungana kusingade, kuisa pfungwa pakufunganya.
Solution:
Kurukurai zvakare nzira yekurapa yekuburitsa uye giredhi remumiriri wekuburitsa, kugadzirisa mold (demoulding slope split die), dzivirira kurova kwakasimba, isa jasi rejeli zvakaenzana uye kwete kukora zvakanyanya, kurukurazve nezvehukuru hwechigadzirwa chimwe chete, uye gadzira patsva. chirongwa chekugadzirisa.
