I-BMC Hydraulic press forming process method

I-BMC iyisifinyezo se-glass fibre eqiniswe ngepulasitiki ye-unsaturated polyester thermosetting, futhi njengamanje iwuhlobo olusetshenziswa kakhulu lwepulasitiki yokushisa eqinisiwe.

BMC Izici kanye nezicelo
I-BMC inezinto ezinhle zomzimba, zikagesi kanye nemishini, ngakho-ke inezinhlobonhlobo zezinhlelo zokusebenza, njengokukhiqizwa kwezingxenye zemishini njengamapayipi okungenisa, izimbobo zamavalvu, kanye nesembozo somgodi ovamile namarimu.Ibuye isetshenziswe kabanzi kwezokundiza, ukwakhiwa, ifenisha, izinto zikagesi, njll., ezidinga ukumelana nokuzamazama komhlaba, ukuncipha komlilo, ubuhle nokuqina.

Izici zokucubungula ze-BMC
1. Uketshezi: I-BMC inoketshezi oluhle futhi ingagcina uketshezi oluhle ngaphansi kwengcindezi ephansi.
2. Ukuphulukiswa: Ijubane lokuphulukisa le-BMC lishesha kakhulu, futhi isikhathi sokuphulukisa singamasekhondi angu-30-60/mm lapho izinga lokushisa lokubumba lingu-135-145°C.
3. Izinga lokushwabana: Izinga lokushwabana kwe-BMC liphansi kakhulu, phakathi kuka-0-0.5%.Izinga lokuncipha lingabuye lilungiswe ngokungeza izithasiselo njengoba kudingeka.Ingahlukaniswa ngamaleveli amathathu: akukho ukushwabana, ukushwabana okuphansi, nokuncipha okukhulu.
4. Umbala: I-BMC inombala omuhle.
5. Ukungalungi: isikhathi sokubumba side kakhulu, futhi i-burr yomkhiqizo inkulu kakhulu.

Ukubunjwa kokucindezela kwe-BMC
I-BMC compression molding iwukwengeza inani elithile lenhlanganisela yokubumba (i-agglomerate) ibe isikhunta esishisiwe, ukucindezela nokushisa, bese uqinisa futhi umise.Inqubo ethile inesisindo→ukufunza→ukubumba→ukugcwalisa (i-agglomerate ingaphansi kwengcindezi Iyageleza futhi igcwalise isikhunta sonke)→ukwelapha→(yelashwe ngokugcwele ngemva kokuyigcina isezingeni elibekiwe kanye nezinga lokushisa isikhathi esithile)→ukuvula isikhunta bumba bese ukhipha umkhiqizo→gaya i-burr, njll.→umkhiqizo oqediwe.

Izimo zenqubo yokubumba yokucindezelwa kwe-BMC
1. Ukucindezela kokubumba: I-3.5-7MPa yemikhiqizo evamile, i-14MPa yemikhiqizo enezidingo eziphezulu eziphezulu.
2. Izinga lokushisa lokubumba: Izinga lokushisa lesikhunta livamise ukuba ngu-145±5°C, futhi izinga lokushisa elimisiwe lesikhunta lingehliswa ngo-5-15°C ukuze lidilizwe.
3. Isivinini se-Mold clamping: i-mold clamping engcono kakhulu ingaqedwa phakathi nemizuzwana engu-50.
4. Isikhathi sokuphulukisa: Isikhathi sokuphulukisa somkhiqizo onobukhulu bodonga obuyi-3mm imizuzu engu-3, ​​isikhathi sokuphulukisa ngodonga oluyi-6mm imizuzu engu-4-6, futhi isikhathi sokuphulukisa ngodonga oluyi-12mm luyi-6-10. imizuzu.
