Kuyerekeza kwa zinthu zophatikizika za SMC ndi zitsulo:
1) Conductivity
Zitsulo zonse zimayendetsa, ndipo mkati mwa bokosi lopangidwa ndi zitsulo liyenera kutsekedwa, ndipo mtunda wina uyenera kusiyidwa ngati lamba wodzipatula pakuyika bokosi.Pali kutayikira chobisika ngozi ndi kuwononga danga.
SMC ndi pulasitiki ya thermosetting yokhala ndi kukana pamwamba kuposa 1012Ω.Ndi insulating material.Imakhala ndi kukana kwamphamvu kwambiri komanso kusweka kwamagetsi, komwe kumatha kuletsa ngozi zotuluka, kukhalabe ndi ma dielectric abwino pama frequency apamwamba, ndipo sikuwonetsa kapena kutsekereza.Kufalikira kwa ma microwave kumatha kupewa kugwedezeka kwamagetsi m'bokosi, ndipo chitetezo ndichokwera.
2) Maonekedwe
Chifukwa cha zovuta kwambiri kukonza zitsulo, mawonekedwe apamwamba ndi osavuta.Ngati mukufuna kupanga mawonekedwe okongola, mtengo wake udzawonjezeka kwambiri.
SMC ndiyosavuta kupanga.Zimapangidwa ndi nkhungu yachitsulo pansi pa kutentha kwakukulu ndi kuthamanga kwakukulu, kotero mawonekedwewo akhoza kukhala apadera.Pamwamba pa bokosilo amapangidwa ndi ma protrusions ooneka ngati diamondi, ndipo SMC imatha kupakidwa utoto mosasamala.Mitundu yosiyanasiyana imatha kusinthidwa malinga ndi zosowa za makasitomala.
3) Kulemera
Mphamvu yokoka yachitsulo nthawi zambiri imakhala 6-8g/cm3 ndipo mphamvu yokoka ya zinthu za SMC nthawi zambiri saposa 2 g/cm3.Kulemera kwapansi kumapangitsa kuti pakhale mayendedwe, kupangitsa kukhazikitsa kosavuta komanso kosavuta, ndikupulumutsa kwambiri ndalama zoyendera ndi kukhazikitsa.
4) Kukana kwa dzimbiri
Bokosi lachitsulo silimalimbana ndi dzimbiri la asidi ndi alkali, ndipo n'zosavuta kuchita dzimbiri ndi kuwonongeka: ngati likugwiritsidwa ntchito ndi utoto wotsutsa dzimbiri, choyamba, lidzakhala ndi zotsatira zina pa chilengedwe panthawi yojambula, ndi zatsopano. utoto wotsutsa dzimbiri uyenera kutengedwa zaka 2 zilizonse.Zotsatira za dzimbiri zimatha kupezeka kokha ndi chithandizo, chomwe chimawonjezera kwambiri mtengo wokonzekera pambuyo pake, komanso zimakhala zovuta kugwira ntchito.
Zogulitsa za SMC zili ndi kukana bwino kwa dzimbiri ndipo zimatha kukana dzimbiri lamadzi, mafuta, mowa, mchere wa electrolytic, acetic acid, hydrochloric acid, mankhwala a sodium-potaziyamu, mkodzo, phula, asidi osiyanasiyana ndi nthaka, ndi mvula ya asidi.Chogulitsacho chokha sichikhala ndi ntchito yabwino yotsutsa kukalamba.Pamwamba pa mankhwala ali ndi chitetezo wosanjikiza ndi mphamvu UV kukana.Kutetezedwa kwapawiri kumapangitsa kuti mankhwalawa akhale ndi magwiridwe antchito apamwamba oletsa kukalamba: oyenera nyengo yamtundu uliwonse, m'malo a -50C—+150 madigiri Celsius, Imatha kukhalabe ndi zinthu zabwino zakuthupi ndi zamakina, ndipo mulingo wachitetezo ndi IP54.Zogulitsazo zimakhala ndi moyo wautali wautumiki ndipo ndizosakonza.
SMC poyerekeza ndi ma thermoplastics ena:
1) Kukana kukalamba
Thermoplastics ali ndi kukana kukalamba kochepa.Mukagwiritsidwa ntchito panja kwa nthawi yayitali, chopukutiracho chidzawonekera ku kuwala ndi mvula, ndipo pamwamba pake mosavuta kusintha mtundu ndi kusanduka wakuda, kusweka ndi kukhala brittle, motero zimakhudza mphamvu ndi maonekedwe a mankhwala.
SMC ndi pulasitiki ya thermosetting, yomwe imakhala yosasungunuka komanso yosasungunuka ikachiritsidwa, ndipo imakhala ndi kukana kwa dzimbiri.Ikhoza kukhalabe ndi mphamvu zambiri komanso maonekedwe abwino pambuyo pa ntchito yakunja kwa nthawi yaitali.
2) Kugwa
Thermoplastics zonse zimakhala ndi zokwawa.Pansi pa mphamvu ya kunja kwa nthawi yayitali kapena mphamvu yodziyesa, kuchuluka kwa deformation kudzachitika, ndipo mankhwala omalizidwa sangathe kugwiritsidwa ntchito kwa nthawi yaitali.Pambuyo pa zaka 3-5, iyenera kusinthidwa yonse, zomwe zimapangitsa kuti ziwonongeke zambiri.
SMC ndi thermosetting material, yomwe ilibe zokwawa, ndipo imatha kusunga chikhalidwe chake choyambirira popanda kupunduka pambuyo pa kugwiritsidwa ntchito kwa nthawi yaitali.Zogulitsa za General SMC zitha kugwiritsidwa ntchito kwa zaka zosachepera khumi.
3) Kukhazikika
Zipangizo za Thermoplastic zimakhala zolimba kwambiri koma zosakwanira, ndipo ndizoyenera kuzinthu zazing'ono, zosanyamula katundu, osati zazitali, zazikulu komanso zazikulu.
