Thatha ukuthi uqonde inqubo yokukhiqiza yebhodi lendwangu yengilazi ye-epoxy
Thatha ukuthi uqonde inqubo yokukhiqiza yebhodi lendwangu yengilazi ye-epoxy
Inqubo yokukhiqiza yebhodi lendwangu yengilazi ye-epoxy:
(1) Itheyiphu iyasikwa. Inqubo ukusika itheyipu ibe usayizi othize, futhi imishini yokusika ingaba isisiki esiqhubekayo sobude obumisiwe, noma ingasikwa ngesandla. Ukusika itheyiphu kudinga usayizi onembile, intengo yebhodi ye-epoxy engu-3240, beka itheyiphu esikiwe kahle, abakhiqizi bebhodi le-epoxy abangu-3240, beka amateyipu anokuqukethwe kweglue okuhlukile kanye noketshezi ngokuhlukana, yenza amarekhodi futhi uwagcine ukuze asetshenziswe esikhathini esizayo.
(2) Indwangu yokunamathisela iyakhethwa. Inqubo yokukhetha ye-adhesive tape ibaluleke kakhulu kwikhwalithi ye-laminate. Uma ukukhethwa kungalungile, i-laminate izoqhekeka futhi ubuso buhlakazeke kanye nezinye iziphambeko zizokwenzeka. Emgqeni ongaphezulu webhodi elikhethiwe, amashidi angu-2 we-adhesive tape enokuqukethwe okuphezulu kweglue kanye ne-fluidity ephezulu kufanele abekwe ohlangothini ngalunye. Okuqukethwe okuguquguqukayo akufanele kube kukhulu kakhulu. Uma okuqukethwe okuguquguqukayo kukukhulu kakhulu, kufanele komiswe ngaphambi kokusetshenziswa.
(3) Inqubo yokucindezela okushisayo. Isihluthulelo senqubo yokucindezela yimingcele yenqubo, phakathi kwayo imingcele yenqubo izinga lokushisa, ingcindezi kanye nesikhathi. Nqoba umfutho we-vapor of volatiles, yenza i-resin eboshiwe igeleze, futhi wenze isendlalelo sokunamathisela sisondele eduze; vimbela ipuleti ukuthi lingakhubazeki lapho selipholile. Ubukhulu bengcindezi yokubumba bunqunywa ngokusho kwezici zokuphulukisa ze-resin. Ngokuvamile i-epoxy/phenolic laminate ingu-5.9MPa, kanti ishidi le-epoxy lingu-3.9-5.9MPa.
(4) Ngemuva kokucubungula. Inhloso yokwelashwa kwangemva kokwelashwa ukuqhubeka nokwelapha i-resin kuze kube yilapho ilashwa ngokuphelele, ngesikhathi esifanayo iqede ingxenye yokucindezeleka kwangaphakathi komkhiqizo, futhi ithuthukise ukusebenza kokubopha komkhiqizo. Ukwelashwa kwangemuva kwebhodi le-epoxy kanye nebhodi le-epoxy/phenolic kugcinwa ezingeni lokushisa elingu-130-150℃ cishe i-150min.
