Eli candelo ukusetyenziswa kufuna kwinqanaba eliphezulu ngokwasekomeleleni yanele ukoyisa i-thermal kunye mintshikilelo mechanical. Zakutshanje zenzeke ngexesha bazishiya imiphezulu zizonke, kwaye ukususa amanqaku ukusuka matrix. Ukuba ucinga kukho gelcoat, ukuba yintoni na, oko kuya kuba kubalulekile ukwazi. It zingenziwa yentlaka, leyo enemvelaphi ezahlukeneyo. Noko ke, izinto ezininzi eziqhelekileyo zithathwa ukuba zenziwe nentlaka epoxy kwakunye polyesters ezihluthiyo.

Iimpawu eziphambili

Ukuba ugqiba ekubeni kuthenga gelcoat, ukusetyenziswa esele ezichazwe ngasentla, kubalulekile ukuba uqwalasele iimpawu ezisemgangathweni ezingundoqo, phakathi kwazo ezi iipropati enomtsalane emzimbeni mechanical kwakunye ukuxhathisa ekukhanyeni yelanga, ukufuma, kunye nobuninzi ngeemeko zokusingqongileyo. Ekwenziweni zombala ezisetyenzisiweyo kunye isiseko intlaka esemgangathweni premium. gelcoat Lubonakala kwakhona wokunciphisa phantsi amacandelo eziyingozi. Kuba izicelo ezahlukeneyo ezithengiswayo, unako ukufumana uluhlu olubanzi le mveliso.

Iimpawu ze isicelo

Gelcoat, ichazwe kwinqaku ogama iipropati iqulathe amanye amacandelo ezinobungozi yohlobo styrene. Oku kunokubangela uphuhliso negazi lakho. Kubalulekile ukuthatha ingqalelo phambi kokuba ukusetyenziswa ukuba izinto nto ezinokutsha kwaye kuyingozi ukuba uphefumlela kucaphukisa inkqubo yokuphefumla, amehlo kunye nesikhumba. Kubalulekile ukuba kukhunjulwe ukuba gelcoat kungabangela ukonzakala okukhulu, ukuba kangangexesha elide basezela umphunga. Inkosi kufuneka ubambe izinto kangangoko kunokwenzeka ukusuka kwimithombo ye ucinezelo, musa kutshaya ngexesha ukusetyenziswa, ukuba ningazami basezela umsi, yaye kwimeko zoqhagamshelwano ngamehlo, pula ngokukhawuleza amanzi aphilileyo aze adibane nogqirha. Ngaphambi kokuba isicelo, anxibe ukhuseleko ngokuba ubuso amehlo, ngokunjalo iiglavu. Sebenzisa i eswele kwiindawo kakuhle umoya kuphela. Xa kusenzeka umlilo, kucetyiswa ukuba usebenzise amagwebu, ukutshiza amanzi, imichiza ezomileyo, inkungu amanzi.

Izindululo zokusetyenziswa

Ukuba odibene kokuthengisa gelcoat, leyo ufuna izinto ezinjalo, ube uyakwazi ukufunda kweli nqaku. Sele phambi ukusebenzisa ziyafumaneka kunye nesicelo. Ngenxa yoko, iqondo lobushushu eziphathekayo kunye nezixhobo kufuneka ingadluli degrees 25, kodwa kufuneka lehle degrees 18. Ukuba lobushushu iphantsi kakhulu, inyathelo ayengawokuphilisa iyaphumelela. Oku kunokubangela iziphene. Phambi ukusetyenziswa, izinto kufuneka wenziwe kwisingxobo, uze uyibeke kuyo anenani elifunekayo ngezakhono, umthamo yayo kwanele ukongeza-2% kuvala. Izithako emva kokuba uxhulumaniso kufuneka ngocoselelo kuxutywe. Isicelo kophawu yejeli kufuneka kwenziwe ibrashi ngokwemaleko ezimbini, oko kufuneka kwenziwe ngononophelo unako ukufumana maleko agudileyo, ngaphandle amaqamza okanye mzali. Phakathi kwezibini zomaleko kubalulekile ukuba alinde ixesha ziyahlala.

Izinto zobumnini nokusebenzisa gelcoat ukutshiza

Olunye uhlobo - oko iidyasi, apho isicelo ngaphakathi emzimbeni, yenziwe fiberglass. Oku kwenza ubuso nokuba nomtsalane ngakumbi. Leyo into olele ephilisa inyathelo, ekubeni ngexesha nokuveliswa izithako yayo idityaniswe amafutha.

isiphelo

Gelcoat, iimpawu, iintlobo eziye ichazwe kweli nqaku, u nga ezithengwe evenkileni ngayo iimpahla ezifanelekileyo. Kubalulekile kuphela ukukhetha umbandela ekunene, ngokulandela imiyalelo kwi iphakheji, kodwa indlela onoxanduva kwinqanaba yesicelo.
