BMC Features da aikace-aikace
BMC yana da kyawawan kaddarorin jiki, lantarki da injina, don haka yana da nau'ikan aikace-aikace iri-iri, kamar samar da sassa na inji kamar bututun ci, murfin bawul, da murfin manhole na gama gari da rims.Hakanan ana amfani da shi sosai a fannin sufurin jiragen sama, gini, daki, kayan lantarki, da dai sauransu, waɗanda ke buƙatar juriyar girgizar ƙasa, jinkirin harshen wuta, kyakkyawa da dorewa.
Hanyoyin sarrafa BMC
1. Fluidity: BMC yana da ruwa mai kyau kuma yana iya kula da ruwa mai kyau a ƙarƙashin ƙananan matsa lamba.
2. Curability: The curing gudun BMC ne in mun gwada da sauri, kuma curing lokaci ne 30-60 seconds / mm lokacin da gyare-gyaren zafin jiki ne 135-145 ° C.
3. Ƙunƙarar ƙima: Yawan raguwar BMC yana da ƙasa sosai, tsakanin 0-0.5%.Hakanan za'a iya daidaita ƙimar raguwa ta ƙara abubuwan da ake buƙata.Ana iya raba shi zuwa matakai uku: babu raguwa, ƙananan raguwa, da babban raguwa.
4. Launi: BMC yana da kyakkyawan launi.
5. Rashin hasara: lokacin gyare-gyaren yana da tsayi sosai, kuma samfurin burr yana da girma.
BMC matsawa gyare-gyare
BMC matsawa gyare-gyare shi ne ƙara wani adadin gyare-gyaren fili (agglomerate) a cikin wani preheated mold, matsi da zafi, sa'an nan kuma ƙarfafa da siffar.Ƙayyadaddun tsari yana auna → ciyarwa → gyare-gyare → cikawa (agglomerate yana ƙarƙashin matsin lamba Yana gudana kuma ya cika dukkan mold) → warkewa → (cikakken warkewa bayan kiyaye shi a matsa lamba da zafin jiki na wani lokaci) → buɗewa mold da fitar da samfur → niƙa da burr, da dai sauransu → ƙare samfurin.
