Uma ufuna ukunciphisa inkinga ye-gelcoat, kubaluleke kakhulu ukubhekisisa ulwazi lwabanye abantu abake baba khona, futhi ufingqe okwenziwa nokungenziwa.
Ufuna ukwenza
Misa uhlobo olulungile lwe-gelcoat ngaphambi kokuqala umsebenzi, qinisekisa ukuthi isikhunta esiphelele nesiphelele sesilungele ukusetshenziswa, futhi ushukumise isigubhu ngasinye kahle kodwa kancane (ukuvikela umoya ukuthi ungabambeki).Ngaphambi kokuqala, qiniseka ukuthi i-gelcoat nesikhunta zisezingeni lokushisa phakathi kuka-16-30 ° C. Okufanelekile, izinga lokushisa lesikhunta kufanele libe ngu-2-3 ° C ngaphezu kokushisa kwe-gelcoat.Ibe isiqala ukuphulukisa lapho ithintana, yenze ubuso bushelelezi.
Gcina umswakama ohlobene ungaphansi kuka-8O%.Ngisho nasemazingeni okushisa aphakeme, ukugcwala okuphezulu komhwamuko wamanzi endaweni yokusebenza kungaholela ekwelapheni okunganele.Kubalulekile futhi ukuvimbela amanzi ukuthi angafinyeleli ebusweni besikhunta.
Qinisekisa ukuthi isikhunta siphathwa kahle nge-ejenti yokukhulula.Ungasebenzisi i-ejenti yokukhishwa kwe-silicone.Imikhiqizo esekwe emanzini kumele yomiswe ngokuphelele ngaphambi kokufakwa kwe-gelcoat.I-Gelcoat ingasetshenziswa ngokushesha.Ungangezi izincibilikisi njenge-acetone.I-styrene kufika ku-2% Ingase yengezwe uma isicelo sidinga i-viscosity ephansi.
Okuqukethwe kwe-catalytic ye-MEKP bekungama-2%.Uma okuqukethwe kwe-catalyst kuphezulu kakhulu noma kuphansi kakhulu, ukwelapha okunganele kuzonciphisa ukumelana nesimo sezulu kanye nokumelana namanzi kwe-gelcoat.
Uma i-pigment ingeziwe, qinisekisa ukushesha kombala nokuhambisana ngaphambi kokusetshenziswa.Engeza inani elinconywayo le-pigment, ukale ngokunembile futhi uhlanganise usebenzisa imishini yokugunda ephansi.
Lapho ufutha, ubukhulu kufanele bukhuphuke bufike ezingeni olifunayo phakathi kuka-3 noma izikhathi ukuze kukhishwe amabhamuza amahle.
Uma i-gelcoat ifuthwe, qiniseka ukuthi ufaka ngokulinganayo ijeli enama-microns angama-400 kuya kwangu-600 (okulingana namagremu angama-550-700 ngemitha yesikwele) usebenzisa isilungiselelo esilungile se-nozzle kanye nokucindezela kanye nebanga.I-gelcoat enogqinsi oluncane ingase ingelapheki ngokwanele, kuyilapho i-gelcoat enogqinsi olukhudlwana ingase igijime, iqhekeke futhi ithuthukise izimbotshana.Sebenzisa igeji ukuhlola ukujiya okufanele futhi uqinisekise ukuthi isikhunta sinomoya okahle.Umhwamuko we-styrene monomer uzovimbela i-polymerization futhi ngenxa yamandla adonsela phansi athile avame ukuhlala engxenyeni engezansi yesikhunta ngokushesha nje lapho i-gelcoat selapheke ngokugcwele (ifilimu eqinile, kodwa izwakala inamathele), isendlalelo esiyisipele sisetshenziswa.
Ungakwenzi
Ungabambi umoya oweqile ngesikhathi sokuxuba i-catalyst ne-pigment
Ungasebenzisi imishini yokuxuba ephezulu ye-shear, okungase kubangele ukulimala kwe-thixotropic, ukuhlukaniswa kwe-pigment / flocculation, i-drainage kanye nokufaka umoya.
Ungahlambululi i-gelcoat nge-solvent ngaphandle kwe-styrene monomer.Lapho ungeza i-styrene, okuqukethwe okuphezulu akufanele kudlule u-2%.
Ungathululi i-gelcoat ngqo kwisikhunta ngaphambi kokuxubha (lokhu kuzodala izithunzi).
Ungafaki isikhathi sejeli ngokushesha okukhulu, lokhu akuvumeli umoya osele ukuba uphume.
Ungasebenzisi ngaphezulu noma ngaphansi kwe-catalyst noma i-pigment.
Ungasebenzisi i-silicone wax ngoba ingabangela i-fisheye.
MAYELANA NATHI
I-hebei Yuniu Fiberglass Manufacturing Co., LTD.Sikhiqiza futhi sithengise imikhiqizo ye-e-type fiberglass, efana ne-fiberglass roving, usilika oqoshiwe we-fiberglass, i-fiberglass oqoshiwe wazizwa, i-fiberglass gingham, inzwa yokuzwa inaliti, indwangu ye-fiberglass nokunye.Uma kukhona izidingo, sicela usithinte ngokukhululekile.
Iziphakamiso zemikhiqizo yesikhunta esikhulu
Ngenxa yezindleko eziphezulu ezihilelekile ekuhlanganisweni kwejeli yesikhunta esikhulu esifana nezigodlo zemikhumbi namadekhi, kunconywa ukuthi kukhiqizwe ngosayizi okwanele oxutshwe ngaphambili ngumkhiqizi ngoba umbala webala ugaywa ngqo kujeli ngesikhathi sokulawulwa. ukukhiqiza.
Kungakhathaliseki ukuthi iyiphi indlela esetshenzisiwe, izinto ezifanayo ezilindelekile (okuhlanganisa i-laminate yokuqala, umthamo we-catalyst, ubuciko bokuxuba, izimo ze-workshop kanye no-opharetha) kufanele zisetshenziswe ukukhiqiza amaphaneli amancane okuhlola ngaphambi kokuqala ukukhiqizwa kwesikhunta.Ingaphezulu lingase lihlolwe ukuthi alinasici yini kanye nokuqina kwe-gelcoat okungaphezulu kuhlolwe kusetshenziswa imitha ye-Barcol ngaphambi kokuthi ukukhiqizwa kuqale.
