Kodi njira yayikulu kwambiri ya bolodi la mica epoxy galasi CHIKWANGWANI bolodi

1. Kuyika chonyowa pamanja

Ikani womasulira ndi wosanjikiza wa sing’anga-yogwiritsira ntchito madzi otsekemera otsekemera ndi mamasukidwe akayendedwe a 0.3-0.4PaS pamwamba pa nkhungu nawonso (pambuyo poti chovala cha gelisi chazunguliridwa) ndi chingwe chazitsulo zolimbitsa. Zida zopangidwa ndi fiber zimamveka pamwamba komanso zosakhota Pali mitundu ingapo ya gauze (nsalu yonyezimira). Gwiritsani chozungulira kapena burashi yonyamula m’manja kuti muphatikize utomoni ndi zinthu zolimbikitsidwa ndi fiber, kutulutsa thovu la mpweya, ndikuphatika m’munsi mwake. Ntchito zoyika zimabwerezedwa kangapo mpaka makulidwe akapangidwe kazinthuzo akafika. Utomoniwu umachiritsidwa kutentha chifukwa cha kupopera mphamvu. Itha kutenthedwa kuti imathandizira kuchiritsa. Pakadali pano, kuyika manja ndiye mawonekedwe akulu ku China, omwe amakhala pafupifupi 80% yazinthu zopangira utomoni.

2. jekeseni utomoni ndi utomoni kutengerapo RTM akamaumba

RTM ndi njira yokhotakhota yotsika pang’ono. Ikani zinthu zolimbitsa pakati pazitsulo zakumtunda ndi zapansi; kutseka nkhungu ndikumangirira nkhungu; jekeseni utomoni mopanikizika; tsegulani nkhungu utomoni utachiritsidwa, ndikuchotsani mankhwalawo. Ndondomeko ya utomoni isanayambike, utomoni uyenera kudzazidwa mchikombole, ndipo kukakamizidwa kumapangitsa utomoniwo kuti usinthe mwachangu nkhungu ndikupatsanso fiber.

3. Kuumba pepala SMC (BMC yambiri)

Onjezani oyambitsa, odzaza, inki, zotulutsa nkhungu zamkati, zowonjezera zowonjezera, thickeners, ndi zina zambiri mu utomoni, ndikuzisakaniza kuti apange utomoni. Phala la utomoni limagwera mufilimu wapansi wa gawo la SMC (lomwe limagwiritsidwa ntchito kwambiri ndi polyethylene kapena kanema wa nayiloni), ndipo nthawi yomweyo, limakhazikika mufilimu wotsika ndikudulidwa zingwe zopangira magalasi a 25-55mm, kenako limakutidwa ndi filimuyi kuti ikhale pepala. Mpukutu wa sangweji. Sungani koyiloyo kwa masiku angapo kuti muchepetse zinthuzo kuti mufike pachikuto chokwanira. SMC imaperekedwa ngati chobwezera m’malo opumata. Chophimbacho chimatsegulidwa, chimadulidwa, chimayesedwa, chimayikidwa mu platinamu yachitsulo yotentha, ndikulimbikitsidwa kuti ilimbe ndikuwumba, kenako zomwe zatsirizidwa zimapezeka.
