Kutengera inu kumvetsa ndondomeko kupanga epoxy galasi nsalu bolodi
Njira yopanga ma epoxy glass cloth board:
(1) Tepiyo yadulidwa. Njirayi ndikudula tepiyo mu kukula kwake, ndipo zida zodulira zimatha kukhala chodulira chokhazikika chokhazikika, kapena chikhoza kudulidwa ndi dzanja. Kudula tepi kumafuna kukula kolondola, mtengo wa 3240 epoxy board, sungani tepi yodulidwa bwino, 3240 opanga bolodi la epoxy, sungani matepi okhala ndi guluu wosiyanasiyana ndi fluidity payokha, pangani zolemba ndikuzisunga kuti mugwiritse ntchito mtsogolo.
(2) Nsalu zomatira ndizosankha. Kusankhidwa kwa tepi yomatira ndikofunikira kwambiri pamtundu wa laminate. Ngati kusankhidwa kuli kosayenera, laminate idzaphwanyidwa ndipo pamwamba pake idzaphwanyidwa ndi zolakwika zina. Pamwamba pa bolodi losankhidwa, mapepala a 2 a tepi yomatira okhala ndi zomatira zapamwamba komanso zamadzimadzi zambiri ziyenera kuikidwa mbali iliyonse. Zosakhazikika siziyenera kukhala zazikulu. Ngati zowonda zili zazikulu kwambiri, ziyenera kuumitsidwa musanagwiritse ntchito.
(3) Kukanikiza kotentha. Chinsinsi cha kukanikiza ndondomeko ndi magawo ndondomeko, amene ndondomeko magawo ndi kutentha, kuthamanga ndi nthawi. Gonjetsani kupsinjika kwa nthunzi kwa kugwedezeka, pangani utomoni womangika, ndipo pangani zomatira kuti zigwirizane; kuteteza mbale kuti isapunduke ikazizira. Kukula kwa kukakamiza kowumba kumatsimikiziridwa molingana ndi machiritso a utomoni. Nthawi zambiri epoxy/phenolic laminate ndi 5.9MPa, ndipo pepala la epoxy ndi 3.9-5.9MPa.
(4) Pambuyo pokonza. Cholinga cha mankhwala pambuyo pake ndikuchiritsanso utomoni mpaka utachira, nthawi yomweyo kuchotsa pang’onopang’ono kupsinjika kwamkati kwa mankhwalawa, ndikuwongolera magwiridwe antchito azinthu. Kuchiza kwa epoxy board ndi epoxy/phenolic board kumasungidwa kutentha kwa 130-150 ℃ pafupifupi 150min.
