I-BMC sisishunqulelo sefayibha yeglasi eyomelezwe kwiplastiki yepolyester ethermosetting, kwaye ngoku lolona hlobo lusetyenziswa kakhulu lweplastiki yokuqinisa thermosetting.
Iimpawu ze-BMC kunye nokusetyenziswa
I-BMC ineempawu ezilungileyo zomzimba, zombane kunye nezoomatshini, ngoko ke inoluhlu olubanzi lwezicelo, ezifana nokuveliswa kwamalungu omatshini afana nemibhobho yokungena, izigqubuthelo zevalvu, kunye nezigqubuthelo zomngxuma eziqhelekileyo kunye neerimu.Ikwasetyenziswa ngokubanzi kwinqwelomoya, ulwakhiwo, ifenitshala, izixhobo zombane, njl.njl., ezifuna ukuxhathisa kwenyikima, ukunqanda amadangatye, ubuhle kunye nokuqina.
Iimpawu zokwenziwa kwe-BMC
1. Ulwelo: I-BMC inolwelo olulungileyo kwaye inokugcina ulwelo oluhle phantsi koxinzelelo oluphantsi.
2. Ukunyangeka: Isantya sokunyanga se-BMC sikhawuleza ngokukhawuleza, kwaye ixesha lokunyanga liyi-30-60 imizuzwana / mm xa ubushushu bokubumba buyi-135-145 ° C.
3. Izinga lokucutheka: Izinga lokuncipha kwe-BMC liphantsi kakhulu, phakathi kwe-0-0.5%.Isantya sokucutheka sinokuhlengahlengiswa ngokongeza izongezo njengoko kufuneka.Inokwahlulwa ibe ngamanqanaba amathathu: akukho kuncipha, ukucutha okuphantsi, kunye nokuncipha okuphezulu.
4. Umbala: I-BMC inombala omhle.
5. Ukungalungi: ixesha lokubumba lide, kwaye i-burr yemveliso inkulu.
Ukubumba ukunyanzeliswa kwe-BMC
Ukubumba ukunyanzeliswa kwe-BMC kukongeza inani elithile lokubumba i-agglomerate (i-agglomerate) kwi-mold preheated, i-pressurize kunye nobushushu, kwaye emva koko iqinise kunye nokumila.Inkqubo ethile inika ubunzima→ukutya→ukubumba→ukugcwalisa (iagglomerate iphantsi koxinzelelo Iyaqukuqela kwaye izalise ukungunda okupheleleyo)→ukunyanga→(inyangeke ngokupheleleyo emva kokuyigcina kuxinzelelo olubekiweyo kunye nobushushu kangangexesha elithile)→ivula ukubumba kunye nokukhupha imveliso→ukucola i-burr, njl.→imveliso egqityiweyo.
Iimeko zenkqubo yoxinzelelo lwe-BMC
1. Uxinzelelo lokubumba: 3.5-7MPa kwiimveliso eziqhelekileyo, i-14MPa yeemveliso ezineemfuno eziphezulu eziphezulu.
2. Ubushushu bokubumba: Iqondo lobushushu lokungunda ngokuqhelekileyo li-145 ± 5 ° C, kwaye ubushushu obusisigxina bokubumba bunokwehliswa nge-5-15 ° C ukudiliza.
3. Isantya sokuqinisa umngundo: eyona nto ilungileyo yokubumba umngundo inokugqityezelwa kwimizuzwana engama-50.
4. Ixesha lokunyanga: Ixesha lokunyanga imveliso kunye nobukhulu bodonga lwe-3mm yimizuzu emi-3, ixesha lokunyanga kunye nobukhulu bodonga lwe-6mm yimizuzu emi-4-6, kunye nexesha lokunyanga ngodonga lwe-12mm ngu-6-10. imizuzu.
