Ukuba ufuna ukunciphisa ingxaki ye-gelcoat, kubaluleke kakhulu ukujonga ngokusondeleyo kumava abanye abantu ababelapho, kwaye ushwankathele okwenziwa kunye nokungenziwa.
Ufuna ukwenza
Misa uhlobo oluchanekileyo lwe-gelcoat phambi kokuba uqalise umsebenzi, qinisekisa ukuba ukubumba okupheleleyo kunye nokucokisekileyo kukulungele ukusetyenziswa, kwaye ugxobhoze igubu ngalinye ngokucokisekileyo kodwa ngokucothayo (ukuthintela umoya ekubambeni).Ngaphambi kokuba uqale, qiniseka ukuba i-gelcoat kunye nesikhunta sikwiqondo lokushisa phakathi kwe-16-30 ° C. Ngokufanelekileyo, ukushisa kwe-mold kufuneka kube ngu-2-3 ° C ngaphezu kokushisa kwe-gelcoat.Emva koko iqala ukunyanga xa idibene, yenza umphezulu ube lula.
Gcina ukufuma okuhambelanayo ngaphantsi kwe-8O%.Nakumaqondo obushushu aphakamileyo, ukuxinwa okuphezulu komphunga wamanzi kwindawo yokusebenza kunokukhokelela ekunyangekeni okungonelanga.Kwakhona kubalulekile ukunqanda amanzi ukuba adibanise phezu kwendawo yokubumba.
Qinisekisa ukuba indawo yokubumba iphathwa ngokufanelekileyo nge-arhente yokukhulula.Musa ukusebenzisa i-agent ye-silicone yokukhululwa.Iimveliso ezisekelwe emanzini kufuneka zomiswe ngokupheleleyo ngaphambi kokuba kufakwe i-gelcoat.I-Gelcoat ingasetyenziswa ngokukhawuleza.Musa ukongeza izinyibilikisi ezifana ne-acetone.I-Styrene ukuya kwi-2% Inokongezwa ukuba isicelo sifuna i-viscosity ephantsi.
Umxholo we-catalytic we-MEKP wawuyi-2%.Ukuba umxholo we-catalyst uphezulu kakhulu okanye uphantsi kakhulu, ukunyanga okungonelanga kuya kunciphisa ukuchasana kwemozulu kunye nokuxhatshazwa kwamanzi kwe-gelcoat.
Ukuba i-pigment yongezwa, qinisekisa ukukhawuleza kombala kunye nokuhambelana ngaphambi kokusetyenziswa.Yongeza inani elicetyiswayo le-pigment, ulinganise ngokuchanekileyo kwaye udibanise usebenzisa izixhobo zokucheba eziphantsi.
Xa utshiza, ubukhulu kufuneka bunyuswe kwinqanaba elifunekayo ngaphakathi kwe-3 okanye amaxesha ukukhulula ama-bubbles amahle.
Ukuba i-gelcoat itshiziwe, qiniseka ukuba usebenzise ngokulinganayo ijeli yokwambathisa i-400 ukuya kwi-600 microns (elingana ne-550-700 grams nge-square meter) usebenzisa i-nozzle echanekileyo yokusetha kunye noxinzelelo lokutshiza kunye nomgama.I-Gelcoat enobunzima obuncinci ayinakunyanga ngokwaneleyo, ngelixa i-gelcoat enobunzima obukhulu inokubaleka, iqhekeze kwaye iphuhlise iipores.Sebenzisa igeyiji ukujonga ubungqingqwa obuchanekileyo kwaye uqinisekise ukuba umngundo unomoya owaneleyo.Umphunga we-Styrene monomer uya kuthintela i-polymerization kwaye ngenxa yobunzima bayo obuphezulu obuthile buhlala buhlala kwindawo esezantsi yokungunda ngokukhawuleza ukuba i-gelcoat iphiliswe ngokupheleleyo (ifilimu eqinile, kodwa ivakalelwa kukuba ibambelele), i-spare layer isetyenziswa.
Musa
Musa ukubambisa umoya ogqithisileyo ngexesha lokuxuba i-pigment kunye ne-catalyst
Musa ukusebenzisa izixhobo zokuxuba eziphakamileyo, ezinokubangela umonakalo we-thixotropic, ukuhlukana kwe-pigment / flocculation, i-drainage kunye nokungena emoyeni.
Musa ukuhlambulula i-gelcoat kunye ne-solvent ngaphandle kwe-styrene monomer.Xa ufaka i-styrene, umxholo ophezulu akufanele udlule i-2%.
Musa ukugalela i-gelcoat ngqo kwi-mold ngaphambi kokuxubha (oku kuya kudala izithunzi).
Musa ukusebenzisa ixesha lejeli ngokukhawuleza, oku akuvumeli umoya oshiyekileyo ukuba ubaleke.
Musa ukusebenzisa ngaphezulu okanye ngaphantsi kwe-catalyst okanye i-pigment.
Musa ukusebenzisa i-wax ye-silicone njengoko inokubangela i-fisheye.
NGATHI
hebei Yuniu Fiberglass Manufacturing Co., LTD.Ubukhulu becala sivelisa kwaye sithengise iimveliso ze-e-type fiberglass, ezifana ne-fiberglass roving, i-fiberglass yesilika enqunqiweyo, i-fiberglass eqoshiwe, i-fiberglass gingham, ivakalelwa ngenaliti, ilaphu le-fiberglass kunye nokunye.Ukuba naziphi na iimfuno, nceda uqhagamshelane nathi ngokukhululekileyo.
Iingcebiso zeemveliso zokungunda ezinkulu
Ngenxa yeendleko eziphezulu ezibandakanyekayo ekugqume ijeli yokubumba okukhulu okunje ngeenqanawa zeenqanawa kunye nedesika, kuyacetyiswa ukuba kwenziwe ngobungakanani obuninzi obaneleyo obuxutywe kwangaphambili ngumenzi ngenxa yokuba i-pigment igalelwa ngqo kwijeli yokwaleka ngexesha lolawulo. imveliso.
Nayiphi na indlela esetyenziswayo, izinto ezifanayo ezilindelekileyo (kubandakanywa i-laminate yokuqala, i-catalyst dosage, ubugcisa bokuxuba, iimeko zokusebenzela kunye nomqhubi) kufuneka zisetyenziswe ukuvelisa iipaneli zokuvavanya ezincinci ngaphambi kokuqala ukuveliswa kwesikhunta.Umphezulu unokuhlolwa iziphene kunye nobulukhuni bejelcoat yomphezulu ihlolwe kusetyenziswa imitha yeBarcol phambi kokuba imveliso iqale.
