Kana iwe uchida kuderedza dambudziko regelcoat, zvakakosha kuti utarise zvakanyanya ruzivo rwevamwe vanhu vanga varipo, uye muchidimbu kuita uye kusaita.
Kuda kuita
Gadzira iyo chaiyo gelcoat mhando usati watanga basa, iva nechokwadi chekuti mold yakakwana uye yakakwana yakagadzirira kushandiswa, uye kurunga imwe neimwe ngoma zvakanaka asi zvishoma nezvishoma (kudzivirira mweya kubva pakuteya).Usati watanga, iva nechokwadi chokuti gelcoat uye mold zviri pakupisa pakati pe16-30 ° C. Zvakanaka, kutonhora kwemuumbi kunofanira kuva 2-3 ° C yakakwirira kudarika gelcoat tembiricha.Inobva yatanga kurapa pakubata, ichiita kuti pasi rive nyore.
Chengetedza hunyoro hunyoro pasi pe8O%.Kunyangwe pamatembiricha akakwira, kuwanda kwemhute yemvura munzvimbo yekushanda kunogona kutungamirira mukusakwana kurapwa.Izvo zvakakoshawo kudzivirira mvura kubva mukudonhedza pamusoro peiyo mold.
Ita shuwa kuti mold surface inobatwa nemazvo nemumiririri wekuburitsa.Usashandise silicone yekuburitsa mumiririri.Zvigadzirwa zvemvura zvinofanirwa kuomeswa zvachose gelcoat isati yaiswa.Gelcoat inogona kushandiswa pakarepo.Usawedzera zvinonyungudutsa zvakadai seacetone.Styrene inosvika 2% Inogona kuwedzerwa kana application ichida yakaderera viscosity.
The catalytic content yeMEKP yaive 2%.Kana iyo catalyst yemukati yakawandisa kana yakadzikira, kusakwana kurapa kunoderedza kushomeka kwemamiriro ekunze uye kudzivirira kwemvura kwegelcoat.
Kana pigment yawedzerwa, simbisa kukurumidza kwemavara uye kuenderana usati washandisa.Wedzera huwandu hwakakurudzirwa hwe pigment, kunyatsoyera uye sanganisa uchishandisa yakaderera shear midziyo.
Pakupfapfaidza, ukobvu hunofanira kuwedzerwa kusvika padanho raunoda mukati me3 kana nguva kuburitsa mabhuru akanaka.
Kana gelcoat rikapfapfaidzwa, ita chokwadi chekuisa gel coating ye400 kusvika 600 microns (yakaenzana ne550-700 magiramu paskweya mita) uchishandisa iyo chaiyo nozzle kuseta uye kupfapfaidza kudzvanywa uye kureba.Gelcoat ine hudiki hudiki inogona kusapora zvakakwana, nepo gelcoat ine hombe yakakura inogona kumhanya, kuputika uye kugadzira pores.Shandisa geji kutarisa ukobvu chaihwo uye ita shuwa kuti molds ine mhepo yakanaka.Styrene monomer vapor inodzivirira polymerization uye nekuda kweiyo yakakwirira chaiyo giravhiti inoita kuti irambe iri muchikamu chezasi chekuumbwa nekukurumidza kana gelcoat yanyatsopora (yakaomarara firimu, asi inonzwa inonamira), iyo spare layer inoiswa.
Usadaro
Usapinze mweya wakawandisa panguva yekusanganisa uye pigment kusanganisa
Usashandise high-shear mixing equipment, iyo inogona kukonzera thixotropic kukuvara, pigment kupatsanurwa/flocculation, drainage uye air intrainment.
Usasvibisa gelcoat neine solvent kunze kwe styrene monomer.Paunenge uchiwedzera styrene, iyo yakawanda yemukati haifanire kudarika 2%.
Usadurura gelcoat zvakananga pane mold usati wageza (izvi zvinogadzira mimvuri).
Usashandise gel nguva nekukurumidza, izvi hazvibvumiri mhepo yakasara kutiza.
Usashandise pamusoro kana pasi pecatalyst kana pigment.
Usashandise silicone wax sezvo inogona kukonzera fisheye.
NEZVEDU
Hebei Yuniu Fiberglass Manufacturing Co., LTD.Isu tinonyanya kugadzira uye kutengesa e-mhando fiberglass zvigadzirwa, senge fiberglass roving, fiberglass yakachekwa sirika, fiberglass yakachekwa yakanzwa, fiberglass gingham, inodiwa yakanzwa, fiberglass jira uye zvichingodaro.Kana pane zvaunoda, tapota taura nesu zvakasununguka.
Mazano ezvigadzirwa zvakakura zvekuumbwa
Nekuda kwemutengo wepamusoro unosanganisirwa mukupfekedzwa kwegel kwezviumbwa zvakakura senge mahombe engarava uye madhiketi, zvinokurudzirwa kugadzira nehukuru hwakakwana hwakagara hwakasanganiswa nemugadziri nekuti iyo pigment inogadzikwa yakananga mukati mekuputira gel panguva yekudzora. production.
Chero nzira inoshandiswa, zvinhu zvakafanana zvinotarisirwa (kusanganisira yekutanga laminate, catalyst dosage, kusanganisa art, mamiriro ewekishopu uye mushandisi) zvinofanirwa kushandiswa kugadzira mapaneru madiki ebvunzo usati watanga kugadzira mold.Iyo yepamusoro inogona kutariswa kuti haina kuremara uye kuomarara kwegelcoat yakatariswa uchishandisa Barcol mita isati yatanga kugadzirwa.
