Ngati mukufuna kuchepetsa vuto la gelcoat, ndizofunika kwambiri kuyang'anitsitsa zomwe anthu ena adakumana nazo, ndikufotokozera mwachidule zomwe mungachite ndi zomwe musachite.
Ndikufuna kuchita
Khazikitsani mtundu wolondola wa gelcoat musanayambe ntchito, onetsetsani kuti nkhungu zonse zakonzeka kugwiritsidwa ntchito, ndikugwedeza ng'oma iliyonse bwino koma pang'onopang'ono (kuteteza mpweya kuti usagwire).Musanayambe, onetsetsani kuti gelcoat ndi nkhungu zili pa kutentha pakati pa 16-30 ° C. Moyenera, kutentha kwa nkhungu kuyenera kukhala 2-3 ° C kuposa kutentha kwa gelcoat.Kenako imayamba kuchiritsa pakukhudzana, kupangitsa kuti pamwamba pakhale bwino.
Sungani chinyezi chachibale pansi pa 8O%.Ngakhale pa kutentha kwakukulu, kuchuluka kwa nthunzi wamadzi pamalo ogwirira ntchito kungayambitse kuchira kosakwanira.Ndikofunikanso kuteteza madzi kuti asasunthike pamwamba pa nkhungu.
Onetsetsani kuti nkhungu imasamalidwa bwino ndi wothandizira.Osagwiritsa ntchito silicone yotulutsa.Zopangira madzi ziyenera kuumitsidwa kwathunthu musanapaka gelcoat.Gelcoat ikhoza kugwiritsidwa ntchito nthawi yomweyo.Osawonjezera zosungunulira monga acetone.Styrene mpaka 2% Itha kuwonjezeredwa ngati ntchitoyo ikufuna kukhuthala kochepa.
Zomwe zili mu MEKP zinali 2%.Ngati chothandizira chili chokwera kwambiri kapena chochepa kwambiri, kuchiritsa kosakwanira kumachepetsa kukana kwa nyengo ndi kukana madzi kwa gelcoat.
Ngati pigment yawonjezedwa, onetsetsani kuti mtundu uli wothamanga komanso wogwirizana musanagwiritse ntchito.Onjezerani kuchuluka kovomerezeka kwa pigment, kuyeza molondola ndikusakaniza pogwiritsa ntchito zida zometa ubweya wochepa.
Popopera mbewu mankhwalawa, makulidwewo akuyenera kukulitsidwa mpaka pamlingo womwe mukufuna mkati mwa 3 kapena nthawi kuti mutulutse thovu labwino.
Ngati gelcoat yapopera, onetsetsani kuti mwapaka utoto wa gelsi wa ma microns 400 mpaka 600 (ofanana ndi 550-700 magalamu pa lalikulu mita) pogwiritsa ntchito mawonekedwe olondola a nozzle ndikupopera mphamvu ndi mtunda.Gelcoat yokhala ndi makulidwe ang'onoang'ono sangachiritse bwino, pomwe gelcoat yokhala ndi makulidwe okulirapo imatha kuthamanga, kusweka ndi kupanga pores.Gwiritsani ntchito geji kuti muwone ngati makulidwe ake ndi olondola komanso onetsetsani kuti nkhungu zili ndi mpweya wabwino.Mpweya wa styrene monomer udzalepheretsa polymerization ndipo chifukwa cha mphamvu yokoka yamtengo wapatali imakhalabe m'munsi mwa nkhungu mwamsanga pamene gelcoat imachiritsidwa bwino (filimu yolimba, koma imamveka yomamatira), wosanjikiza wotsalira umagwiritsidwa ntchito.
Osatero
Musatseke mpweya wambiri panthawi yosakaniza ndi pigment
Osagwiritsa ntchito zida zosakaniza zometa ubweya wambiri, zomwe zingayambitse kuwonongeka kwa thixotropic, kulekanitsa kwa pigment / flocculation, ngalande ndi kulowetsa mpweya.
Osachepetsa gelcoat ndi zosungunulira kupatula styrene monomer.Powonjezera styrene, zomwe zili pamwambazi siziyenera kupitirira 2%.
Osatsanulira gelcoat mwachindunji pa nkhungu musanatsuke (izi zimapanga mithunzi).
Osayika nthawi ya gel osakaniza, izi sizilola kuti mpweya wotsalira utuluke.
Osagwiritsa ntchito mowonjezera kapena pansi pa chothandizira kapena pigment.
Osagwiritsa ntchito sera ya silikoni chifukwa imatha kuyambitsa fisheye.
ZAMBIRI ZAIFE
Hebei Yuniu Fiberglass Manufacturing Co., Ltd.Ife makamaka kubala ndi kugulitsa mankhwala e-mtundu fiberglass, monga fiberglass roving, fiberglass akanadulidwa silika, fiberglass akanadulidwa anamva, fiberglass gingham, anamva kusowa, fiberglass nsalu ndi zina zotero.Ngati zosowa, chonde tilankhule momasuka.
Malingaliro azinthu zazikulu za nkhungu
Chifukwa cha kukwera mtengo kwa kupaka ma gel opangira nkhungu zazikulu monga zombo zapamadzi ndi ma desiki, tikulimbikitsidwa kuti tipange ndi kukula kokwanira komwe kudasakanizidwa kale ndi wopanga chifukwa pigment imayikidwa mwachindunji mu zokutira gel panthawi yowongolera. kupanga.
Njira iliyonse yomwe ikugwiritsidwa ntchito, zipangizo zomwezo zomwe zikuyembekezeka (kuphatikizapo laminate yoyamba, chothandizira mlingo, luso losakaniza, zochitika za msonkhano ndi woyendetsa) ziyenera kugwiritsidwa ntchito popanga mapepala ang'onoang'ono oyesera asanayambe kupanga nkhungu.Pamwamba pake pakhoza kuyang'aniridwa ngati pali zolakwika ndi kuuma kwa gelcoat kumayang'aniridwa pogwiritsa ntchito mita ya Barcol isanayambe kupanga.
