Kunamaphuzu amaningana gelcoats ezivamile zenziwa ngesisekelo unsaturated polyester noma epoxy inhlaka.

incazelo jikelele

Izinto ezichazwe njengesithiyo resin Ushintshe, okuyinto sisetshenziswa ewuketshezi ku matrix. Ngemva kokuphothulwa inqubo solidification ukhiqiza polymers ukuthi babe cross-ukuxhumanisa. Ngesikhathi sigaba esilandelayo, le ukuqinisa we esiyinhlanganisela-matrix polymeric ngokuvamile nenye ingilazi fibre kanye polyester resin noma epoxy resin nge glass fibre noma carbon fibre. Uma unesithakazelo gelcoat, yilokhu ungafunda kulesi sihloko. Isetshenziselwa ukuthola indawo ecwebezelayo anemibala, okungaba ngcono ukubonakala imikhiqizo nezimfanelo zabo yobuhle. Kaningi, imikhumbi emikhulu kanye yezikebhe ekhiqizwa usebenzisa izinto esiyinhlanganisela, olwelwesini, esakhiwa ijazi gel has a ukushuba kule ezahlukene amamilimitha angu 0.5 kuya 0.8.

Izici impahla

Uma unquma ukuthenga gelcoat, siyini lesi, kubalulekile ukuqaphela ngaphambi kokuthenga. Ukuze unikeze ngaphezulu ukumelana ezinkulu hydrolysis kanye elangeni, izinhlobo ezikhethekile ezichazwe material okuyinto has a izakhiwo okusezingeni eliphezulu ngokomzimba-lokukhanda. izinguqulo Akhethekile ingasetshenziswa ukwakha matrix, ezisetshenziswa for imikhiqizo yokukhiqiza ngokwabo. Le nkambu ukusetshenziswa kudinga izinga eliphezulu amandla okuyinto kwanele ukuba unqobe lo ezishisayo kanye ekucindezelekeni lokukhanda. Kwakamuva kwenzeke ngesikhathi ukwenqaba evele esiyinhlanganisela, nokususa izihloko ezivela matrix. Uma ucabangela gelcoat, kunjalo nje, kuyoba kubalulekile ukwazi.

Ngo womshini zombala esetshenziswa futhi base resin ka ikhwalithi ye-premium. gelcoat libhekene futhi ekushayweni eliphansi izingxenye eziyingozi. Ukuthola izinhlelo zokusebenza ezahlukene ukudayiswa, ungathola anhlobonhlobo lo mkhiqizo.

Izici isicelo

Gelcoat, ogama izakhiwo ezichazwe sihloko iqukethe ezinye izingxenye eziyingozi yohlobo styrene. Kungabangela ukuthuthukiswa komzimba nezinto. Kubalulekile ukucabangela ngaphambi kokusetshenziswa sokuthi okuqukethwe oluvuthayo kanye yingozi donsa njengoba kuyacasula ukuba imigudu yokuphefumula, amehlo kanye isikhumba. Kubalulekile ukukhumbula ukuthi gelcoat kungabangela ukulimala kakhulu, uma isikhathi eside ukuze donsa Ukhuphula izinkungu. Inkosi kumelwe ubambe izinto ngangokunokwenzeka ezivela emithonjeni ukuthungela, ungabhemi phakathi kokusebenza, zama hhayi donsa intuthu, futhi uma oxhumana naye ngamehlo, kugeze ngokushesha ngokuba namanzi amaningi egijima futhi kudokotela. Ngaphambi isicelo, ukugqoka sokuvikela ubuso namehlo, kanye amagilavu. Sebenzisa izinto kudingeka kuphela ezindaweni kahle umoya. Lapho umlilo kwenzeka, kutuswa ukusebenzisa Foam, amanzi spray, amakhemikhali omile, amanzi inkungu.

Izincomo zokusetshenziswa

Uma elalihlangana ngokuthengisa gelcoat, okuyinto idinga ukwaziswa okunjalo, ungafunda kulesi sihloko. Kakade ngaphambi zisebenzisa ayatholakala nge isicelo. Ngakho, izinga lokushisa kwe-impahla yokusebenza kanye namathuluzi akumele leqe degrees 25, kodwa akufanele uphonsa ngezansi degrees 18. Uma izinga lokushisa uphansi kakhulu, isinyathelo sokwelapha siphumelele. Lokhu kungabangela ukukhubazeka. Ngaphambi ukusetshenziswa, indaba kufanele kube okuxubile esitsheni, bese basibeka lemali edingekayo umthamo, ivolumu okuyinto eyanele ukuze ungeze 2% kulethe. Izithako emva uxhumano kumele kahle exubile. Ukusetshenziswa kwe-ijeli elingenamikhono kufanele kwenziwa ibhulashi e izingqimba ezimbili, ingabe kufanele yenziwe yini ukucophelela ukuthola izingqimba bushelelezi, ngaphandle Bubbles noma nezakhamuzi. Phakathi laphakathi kubalulekile ukulinda isikhathi yokuzigxilisa.

Izakhiwo nokusebenzisa gelcoat sishaye

Ukudayiswa zingatholakala gelcoat eyenzelwe sishaye. Kubalulekile ukusebenzisa izingqimba eziningana mncane, ngaphandle kokulinda ukuba ezomile odlule. Kulokhu, sprayer kumele isethwe at ingcindezi ephansi, ukuhlinzeka ububanzi umlomo wombhobho encane. Phakathi izingqimba kubalulekile ukulinda mayelana 4 imizuzu umoya ukukhululwa. I ukujiya sokugcina ijeli elingenamikhono ilingana 0.8 milimitha.

izinhlobonhlobo gelcoat

Olunye uhlobo - ke topcoats, ezisetshenziswa ngaphakathi emzimbeni, eyenziwe-fiberglass. Lokhu kwenza ebusweni ngisho nangokwengeziwe. into enjalo fast elapha isinyathelo, ngoba ngesikhathi womshini izithako zako yengezwe wax.

isiphetho

Gelcoat, izakhiwo, izinhlobo okuye ochazwe esihlokweni esithi, ungakwazi athengwe esitolo izimpahla ezifanele. Akubalulekile nje kuphela ukukhetha impahla kwesokudla, ulandele imiyalo iphakethe, kodwa futhi indlela obhekene esigabeni isicelo.
