I-BMC isifinyezo sepulasitiki ye-thermosetting ye-polyester engagqwali eqinisiwe ngefayibha yengilazi, futhi okwamanje uhlobo lwepulasitiki ye-thermosetting eqinisiwe esetshenziswa kakhulu.
Izici ze-BMC kanye nezinhlelo zokusebenza
I-BMC inezakhiwo ezinhle zomzimba, zikagesi nezemishini, ngakho-ke inezinhlobo eziningi zezicelo, njengokukhiqizwa kwezingxenye zemishini ezifana namapayipi okungenisa, izembozo zamavalvu, kanye nezembozo zemigodi evame ukusetshenziswa kanye namarimu. Iphinde isetshenziswe kabanzi ezindizeni, ekwakheni, efenisha, ezintweni zikagesi, njll., ezidinga ukumelana nokuzamazama komhlaba, ukubambezeleka komlilo, ubuhle kanye nokuqina.
Izici zokucubungula i-BMC
1. Ukugeleza: I-BMC inokuguquguquka okuhle futhi ingagcina ukugeleza okuhle ngaphansi kwengcindezi ephansi.
2. Ukuphiliswa: Ijubane lokuphiliswa kwe-BMC lishesha kakhulu, futhi isikhathi sokuphiliswa singamasekhondi angu-30-60/mm lapho izinga lokushisa lokubumba lingu-135-145°C.
3. Izinga lokuncipha: Izinga lokuncipha kwe-BMC liphansi kakhulu, phakathi kuka-0-0.5%. Izinga lokuncipha lingalungiswa ngokungeza izithasiselo njengoba kudingeka. Lingahlukaniswa ngamazinga amathathu: ukunganciphi, ukunciphiswa okuphansi, kanye nokunciphiswa okuphezulu.
4. Umbala: I-BMC inombala omuhle.
5. Okubi: isikhathi sokubumba side kakhulu, kanti i-burr yomkhiqizo inkulu kakhulu.
Ukubumba kokucindezela kwe-BMC
Ukubumba kokucindezela kwe-BMC kuhilela ukwengeza inani elithile lenhlanganisela yokubumba (i-agglomerate) ku-mold eshisiwe, icindezele futhi ifudumale, bese iqina futhi ibumbeke. Inqubo ethile inesisindo→ukondla→ukubumba→ukugcwalisa (i-agglomerate ingaphansi kwengcindezi. Igeleza futhi igcwalise i-mold yonke)→iphilisa→(ipholile ngokuphelele ngemva kokuyigcina ku-pressure kanye nokushisa okubekiwe isikhathi esithile)→ukuvula i-mold nokukhipha umkhiqizo→ukugaya i-burr, njll.→umkhiqizo oqediwe.
Izimo zenqubo yokubumba yokucindezelwa kwe-BMC
1. Ingcindezi yokubumba: 3.5-7MPa yemikhiqizo evamile, 14MPa yemikhiqizo enezidingo eziphezulu zobuso.
2. Izinga lokushisa lokubumba: Izinga lokushisa lokubumba ngokuvamile lingu-145±5°C, futhi izinga lokushisa lokubumba elingaguquki lingancishiswa ngo-5-15°C ukuze linciphiswe.
3. Isivinini sokubopha isikhunta: ukubopha isikhunta okungcono kakhulu kungaqedwa ngemizuzwana engama-50.
4. Isikhathi sokuphola: Isikhathi sokuphola somkhiqizo onobukhulu bodonga obungu-3mm siyimizuzu emi-3, isikhathi sokuphola esinobukhulu bodonga obungu-6mm siyimizuzu emi-4-6, kanti isikhathi sokuphola esinobukhulu bodonga obungu-12mm siyimizuzu eyi-6-10.
Isikhathi sokuthunyelwe: Meyi-13-2021
