I-BMC sisifinyezo seplastiki ye-thermosetting ye-glass fiber reinforced unsaturated polyester, kwaye okwangoku lolona hlobo lweplastiki ye-thermosetting eqinisiweyo esetyenziswa kakhulu.
Iimpawu zeBMC kunye nezicelo
I-BMC ineempawu ezintle zomzimba, zombane kunye nezoomatshini, ngoko ke ineendlela ezahlukeneyo zokusetyenziswa, njengokuvelisa iindawo zoomatshini ezifana neepayipi zokungenisa, izigqubuthelo zeevalvu, kunye nezigqubuthelo zemingxuma eqhelekileyo kunye neerim. Ikwasetyenziswa kakhulu kwiinqwelomoya, ulwakhiwo, ifenitshala, izixhobo zombane, njl.njl., ezifuna ukumelana nenyikima, ukubambezeleka komlilo, ubuhle kunye nokuqina.
Iimpawu zokucubungula i-BMC
1. Ukunyibilika: I-BMC inokuguquguquka okuhle kwaye inokugcina ukunyibilika okuhle phantsi koxinzelelo oluphantsi.
2. Ukuchacha: Isantya sokuchacha se-BMC sikhawuleza kakhulu, kwaye ixesha lokuchacha yimizuzwana engama-30-60/mm xa ubushushu bokubumba buyi-135-145°C.
3. Izinga lokuncipha: Izinga lokuncipha kwe-BMC liphantsi kakhulu, phakathi kwe-0-0.5%. Izinga lokuncipha linokulungiswa ngokongeza izongezo njengoko kufuneka. Linokwahlulwa libe ngamanqanaba amathathu: ukunganciphi, ukunciphiswa okuphantsi, kunye nokunciphiswa okuphezulu.
4. Umbala: I-BMC inombala olungileyo.
5. Iingxaki: ixesha lokubumba lide kakhulu, kwaye i-burr yemveliso inkulu kakhulu.
Ukubumba ucinezelo lweBMC
Ukubumba koxinzelelo lwe-BMC kukongeza inani elithile lekhompawundi yokubumba (i-agglomerate) kwi-mold eshushu, icinezelwe kwaye ifudumale, ize iqine kwaye imile. Inkqubo ethile inzima→ ukondla→ ukubumba→ ukuzalisa (i-agglomerate iphantsi koxinzelelo. Ihamba kwaye izalise i-mold yonke)→ iyaphilisa→ (ivuthwe ngokupheleleyo emva kokuyigcina kuxinzelelo olumiselweyo kunye nobushushu ixesha elithile)→ ukuvula i-mold kunye nokukhupha imveliso→ ukugaya i-burr, njl.njl.→ imveliso egqityiweyo.
Iimeko zenkqubo yokubumba ucinezelo lwe-BMC
1. Uxinzelelo lokubumba: 3.5-7MPa kwiimveliso eziqhelekileyo, 14MPa kwiimveliso ezineemfuno eziphezulu zomphezulu.
2. Ubushushu bokubumba: Ubushushu bokubumba ngokubanzi yi-145±5°C, kwaye ubushushu bokubumba obumiselweyo bunokwehliswa nge-5-15°C ukuze kuncitshiswe.
3. Isantya sokubambelela kwisikhunta: eyona sikhunta ingcono kakhulu ingagqitywa kwimizuzwana engama-50.
4. Ixesha lokunyanga: Ixesha lokunyanga lemveliso enobukhulu bodonga obuyi-3mm yimizuzu emi-3, ixesha lokunyanga elinobukhulu bodonga obuyi-6mm yimizuzu emi-4-6, kwaye ixesha lokunyanga elinobukhulu bodonga obuyi-12mm yimizuzu emi-6-10.
Ixesha lokuthumela: Meyi-13-2021
