SMC (Sheet Molding Compound) inoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri emazuva ano nekuda kwehunhu hwayo hwakanaka hwakadai sekurema kwayo, simba rayo guru uye kuramba kwayo ngura. Zvisinei, mukugadzirwa kwayo chaiko uye kushandiswa kwayo, zvikanganiso zvemukati mechinhu chisingaoneki zvinowanzokanganisa kunaka kwechigadzirwa. Munguva pfupi yapfuura, takagamuchira sampuli dzezvinhu zveSMC dzisina kunaka dzakatumirwa nemutengi. Pamwe chete nesampuli dzeSMC dzakatumirwa, tichagadzirisa nekutsanangura zvakadzama maitiro ekugadzira sampuli dzemetallographic dzehunyanzvi uye maitiro ese ekutarisa mamicroscope, tichikupa gwara rinoshanda kwazvo rekuongorora mamicroscope ezvinhu zvakasanganiswa.
Kucheka Kwemuenzaniso: Chidimbu chekuyedza cheSMC chine zvikanganiso zvekutsemuka chinochekwa nemazvo nemuchina wekucheka wesimbi. Munguva yekushanda, kumhanya kwekucheka uye mwero wekudya zvinodzorwa zvakasimba kudzivirira kukuvara kwechipiri kunzvimbo yakatsemuka kunokonzerwa nekumanikidzwa kwemuchina. Panguva iyi, nzvimbo yekucheka inoonekwa kuti yakati sandara uye haina burr kuti isangane nezvinodiwa zvekugadzirira sampuro inotevera.
Kugadzirira Kuisa Cold: Isa sampuli yakachekwa nemazvo muchimiro chekuisa che cold mounting press, wobva wadira zvishoma nezvishoma mu cold mounting resin. Iva nechokwadi chekuti resin yafukidza zvakakwana nzvimbo yakatsemuka nenzvimbo yakapoteredza sampuli isina mabubbles kana ma voids. Rega igare patembiricha yemukamuri kusvika resin yapora zvakakwana uye yaumbwa, uchishandura sampuli kuita bhokisi rakagadzikwa nguva dzose kuti zvive nyore kukuya nekupukuta mushure mezvo.
Kukuya uye Kupukuta kwemuenzaniso: Muenzaniso wakaiswa muchando uye wakaporeswa unozoshandiswa kukuya nekupukuta zvinyoro nyoro uchishandisa muchina wemetallographic grinding nekupukuta. Padanho rekukuya, mapepa ekukwesha ane saizi dzakasiyana anoshandiswa mukudonha kwegrit. Simba rakafanana rinoiswa pamusoro pemuenzaniso panguva yekushanda kuti ubvise zvishoma nezvishoma mavanga ekucheka. Mushure mekukuya, jira rekupukuta rakafanana uye mushonga wekupukuta zvinoshandiswa pakupukuta zvinyoro nyoro kusvika pamusoro pemuenzaniso waona girazi pasina kukwenya, maburi kana zvimwe zvisizvo.
Kucherechedza neMicroscopic: Pakuongorora kutsemuka kwezvinhu zveSMC, maikorosikopu yesimbi yemhando yepamusoro inogona kupa mifananidzo yakajeka uye yakasiyana-siyana. Isa sampuli yakagadzirwa zvakanaka pachikuva chemaikorosikopu yesimbi, uye gadzirisa nzvimbo yechikuva kuti ienderane zvakanaka nenzvimbo yakatsemuka yechikuva negirazi remaikorosikopu. Nekugadzirisa kukura kwemaikorosikopu, tarisa nzvimbo yekutsemuka, nzira yekupararira kwetsaona uye chimiro che microstructure chakakomberedza nhanho nhanho kubva pakukura kwakaderera kusvika pakukura kwakakwirira. Panguva iyi, nyora mifananidzo nedata zvizere, kuitira kuti upe hwaro hwakarurama hwe microscopic morphology yekuongorora kunotevera kwezvikonzero zvekutsemuka kwezvinhu.
Kana muchifarira michina iyi yekugadzirira mienzaniso uye maikorosikopu yesimbi, ndapota onai runyorwa rwezvigadzirwa uye inzwa wakasununguka kutibata kuti muzive zvakawanda nezvazvo.
