Ntụnyere nke ihe mejupụtara SMC na ihe ígwè:
1) Nhazigharị
Ọla niile na-eduzi ihe, a ga-etinyerịrị ihe owuwu dị n'ime igbe e ji ígwè mee, a ga-ahapụkwa anya ụfọdụ dị ka eriri iche mgbe a na-etinye igbe ahụ. E nwere ihe egwu zoro ezo nke na-agbapụta mmiri na ihe efu nke oghere.
SMC bụ plastik thermosetting nke nwere ike iguzogide elu karịa 1012Ω. Ọ bụ ihe mkpuchi. O nwere ike iguzogide mkpuchi arụmọrụ dị elu na voltaji mmebi, nke nwere ike igbochi ihe mberede ntapu, na-enwe ezigbo ihe onwunwe dielectric na ugboro ugboro dị elu, ọ naghịkwa egosipụta ma ọ bụ gbochie ya. Mgbasa nke microwave nwere ike izere mkpọtụ eletrik nke igbe ahụ, nchekwa ya dịkwa elu.
2) Ọdịdị
N'ihi nhazi ígwè dị mgbagwoju anya, ọdịdị elu ya dị mfe. Ọ bụrụ na ịchọrọ ime ụfọdụ ọdịdị mara mma, ọnụ ahịa ya ga-abawanye nke ukwuu.
SMC dị mfe ịkpụ. E ji ígwè ebu akpụ ya n'okpuru oke okpomọkụ na nrụgide dị elu, yabụ ọdịdị ya nwere ike ịdị iche. E ji ihe ndị dị ka dayamọnd mee elu igbe ahụ, a pụkwara ịcha SMC n'enweghị ihe ọ bụla. Enwere ike ịhazi agba dị iche iche dịka mkpa ndị ahịa si dị.
3) Ibu
Ike ndọda nke ígwè na-abụkarị 6-8g/cm3, ike ndọda nke ihe SMC anaghị agafe 2 g/cm3. Ibu dị ala na-eme ka ibugharị dịkwuo mma, na-eme ka ntinye dị mfe ma dịkwa mfe karị, ma na-echekwa nnukwu ego njem na ntinye.
4) Mgbochi ire ere
Igbe ígwè ahụ anaghị eguzogide nchara asịd na alkali, ọ dịkwa mfe ịcha nchara ma mebie ya: ọ bụrụ na e jiri agba mgbochi nchara gwọọ ya, nke mbụ, ọ ga-enwe mmetụta ụfọdụ na gburugburu ebe obibi n'oge a na-ese ya, a ga-aṅụkwa agba ọhụrụ na-egbochi nchara kwa afọ abụọ. A na-enweta mmetụta mgbochi nchara naanị site na ọgwụgwọ, nke na-eme ka ọnụ ahịa nke mmezi mgbe emechara ya dịkwuo elu, ọ na-esikwa ike ịrụ ọrụ.
Ngwaahịa SMC nwere ezigbo nguzogide nchara ma nwee ike iguzogide nchara nke mmiri, mmanụ ụgbọala, mmanya, nnu electrolytic, acetic acid, hydrochloric acid, sodium-potassium compounds, mmamịrị, asphalt, acid na ala dị iche iche, na mmiri ozuzo acid. Ngwaahịa ahụ n'onwe ya enweghị ezigbo arụmọrụ mgbochi ịka nká. Elu ngwaahịa ahụ nwere oyi akwa nchebe nwere ike iguzogide UV. Nchedo abụọ ahụ na-eme ka ngwaahịa ahụ nwee arụmọrụ mgbochi ịka nká dị elu: dabara adaba maka ụdị ihu igwe ọjọọ niile, na gburugburu ebe obibi -50C—+150 degrees Celsius, Ọ ka nwere ike ịnọgide na-enwe ezigbo ihe onwunwe anụ ahụ na nke mekanikal, ọkwa nchekwa ahụ bụkwa IP54. Ngwaahịa a nwere ndụ ọrụ ogologo oge ma enweghị mmezi.
SMC ma e jiri ya tụnyere thermoplastics ndị ọzọ:
1) Mgbochi ịka nká
Thermoplastics anaghị eguzogide ịka nká. Mgbe ejiri ya n'èzí ruo ogologo oge, ákwà nhicha ahụ ga-apụta ìhè na mmiri ozuzo, elu ya ga-agbanwe agba ngwa ngwa ma gbanwee oji, gbawaa ma gbawaa, si otú a na-emetụta ike na ọdịdị nke ngwaahịa ahụ.
SMC bụ plastik thermosetting, nke anaghị agbaze ma ọ bụ na-agbaze mgbe ọ gwọrọ, ma nwee ezigbo iguzogide nchara. Ọ nwere ike ịnọgide na-enwe ike dị elu ma mara mma mgbe ejiri ya mee ihe n'èzí ogologo oge.
2) Ịrịgharị
Thermoplastics niile nwere ihe ndị na-agagharị agagharị. N'okpuru ike mpụga ogologo oge ma ọ bụ ike inyocha onwe onye, a ga-enwe mgbanwe ụfọdụ, a gaghịkwa eji ngwaahịa emechara eme ihe ruo ogologo oge. Mgbe afọ 3-5 gachara, a ga-agbanwe ya kpamkpam, nke ga-eme ka ọ bụrụ ihe mkpofu dị ukwuu.
SMC bụ ihe na-eme ka okpomọkụ dị jụụ, nke na-enweghị ntụpọ, ọ nwekwara ike ịnọgide na-enwe ọnọdụ mbụ ya na-enweghị mgbanwe mgbe ejiri ya ogologo oge. Enwere ike iji ngwaahịa SMC izugbe mee ihe ruo opekata mpe afọ iri.
3) Isi ike
Ihe ndị e ji thermoplastic mee nwere ike siri ike mana ha anaghị adịkarị mma, ha dịkwa mma naanị maka obere ngwaahịa ndị na-anaghị ebu ibu, ọ bụghị maka ngwaahịa ndị dị ogologo, buru ibu na ndị sara mbara.
