Kuyerekezera zinthu za SMC Cowasite ndi Zida Zitsulo:
1) Zochita
Zitsulo zonse zimachititsa, ndipo mawonekedwe amkati mwa bokosi omwe amapangidwa ndi chitsulo ayenera kukhazikitsidwa, ndipo mtunda wina uyenera kusiyidwa ngati lamba wonyengerera pakukhazikitsa bokosilo. Pali ngozi ina yobisika yobisika komanso kuwononga danga.
SMC ndi pulasitiki ya thermosetting yokhala ndi kutsutsana kwambiri kuposa 1012ω. Ndi zinthu zolimbitsa thupi. Imakhala ndi mphamvu yolimbitsa thupi kwambiri komanso kusweka kwa magetsi, zomwe zingalepheretse ngozi zowononga, zimakhala ndi zinthu zambiri zochulukirapo, ndipo sizikuwonetsa kapena kutseka. Kufalitsa microwaves kumatha kupewa mantha a bokosilo, ndipo chitetezo ndi chapamwamba.
2) mawonekedwe
Chifukwa cha zitsulo zovuta kwambiri, mawonekedwe ake ndi osavuta. Ngati mukufuna kupanga mawonekedwe okongola, mtengo wake udzachuluka kwambiri.
SMC ndi yosavuta kupanga. Amapangidwa ndi nkhungu yachitsulo pansi pa kutentha kwambiri komanso kukakamizidwa kwambiri, kotero mawonekedwe amatha kukhala osiyana ndi ena. Pamwamba pa bokosilo linapangidwa ndi zotupa zooneka ngati diamondi, ndipo SMC imatha kukhala yachikuto. Mitundu yosiyanasiyana imatha kusinthidwa malinga ndi zosowa za kasitomala.
3) Kulemera
Mphamvu Yachitsulo Yachitsulo nthawi zambiri imakhala 6-8g / cm3 ndi mphamvu yokweza ya SMC siyopitilira 2 g / cm3. Kulemera kochepa kumakhala kothandiza kwambiri kunyamula, kuyika siphwemba komanso kosavuta, komanso kunyamula mayendedwe ndi ndalama zokhazikitsa.
4) kukana
Bokosi lachitsulo silikugwirizana ndi asidi ndi alkali mu dzimbiri, ndipo ndizosavuta kuwonongeka kwa chilengedwe, icho chizikhala ndi utoto watsopano wa chilengedwe, ndipo utoto watsopano wotsutsa uyenera kumwedwa zaka ziwiri zilizonse. Mphamvu ya dzimbiri imatha kungogwiritsidwa ntchito ndi chithandizo, yomwe imachulukitsa mtengo wa post-kukonzanso, ndipo ndizovutanso kugwira ntchito.
Zogulitsa za SMC zimatsutsana bwino ndikukana kutupa madzi, mafuta, mowa, mchere wa edium, acerochloric, marlerol, mvula yamayi. Zogulitsa zomwe sizikhala ndi magwiridwe antchito otsutsa. Pamwamba pa malonda ali ndi cholembera choteteza ndi kukana kwamphamvu kwa UV. Chitetezo chachiwiri chimapangitsa kuti malonda akhale ndi magwiridwe antchito apamwamba; Zogulitsazi zimakhala ndi moyo wautali ndipo ndi wopanda ulemu.
SMC poyerekeza ndi a thermoplastics:
1) Kukaniza kukanidwa
Thermoplastics imakhala ndi chizunzo chochepa. Mukamagwiritsa ntchito panja kwa nthawi yayitali, thaulo lidzaonekera kuwunika ndi mvula, ndipo pamwamba imasintha mosavuta ndikusanduka wakuda, kuswa ndikukhala ndi mphamvu, kumawoneka ngati mphamvu.
SMC ndi pulasitiki ya thermosetting, yomwe ili yopanda nzeru komanso yopanda phindu mukachirikiza, ndikutsutsa bwino. Itha kukhala ndi mphamvu zambiri komanso zabwino pambuyo poti mugwiritse ntchito nthawi yayitali.
2) kuzungulira
Thermoplastics onse ali ndi katundu. Mothandizidwa ndi mphamvu yakunja kapena mphamvu yodziyesa nokha, kuchuluka kwa kusokonekera kwina kudzachitika, ndipo chomalizidwa sichingagwiritsidwe ntchito kwa nthawi yayitali. Pakatha zaka 3-5, ziyenera kusinthidwa kwathunthu, zomwe zimapangitsa kuti zisawonongeke.
SMC ndi zinthu za thermoseting, zomwe zilibe kusungunuka, ndipo zimatha kukhalabe ndi dziko loyambirira popanda kusokoneza pambuyo poti mugwiritse ntchito nthawi yayitali. Zogulitsa wamba za SMC zitha kugwiritsidwa ntchito kwa zaka zosachepera khumi.
3) Kukhwima
Zida za Thermoplastic zimakhala zovuta kwambiri koma kukhwima kosakwanira, ndipo ndioyenera kugulitsa zinthu zazing'ono, osakhala ndi katundu, osati kwa zinthu zazitali komanso zazikulu.
