Kupanga ndi kugwiritsa ntchito mapepala owumba

Tsamba loumba limatanthawuza kuti polyester osakhudzidwa ndi polterter ngati thupi lalikulu, wowonjezera wothandizila wothandizidwa, wosungunula, etc. Pepala ili limafotokoza mwachidule kapangidwe kake ndi ntchito ya SMC.

Tsamba loumba ma sheel

SMC imapangidwa ndi zotchinga zosavomerezeka polteter, woyambitsa, woyambitsa, fibrin, Thiclener, amasulidwa, fiberi galasi, ndi polymerization woletsa. Pakati pawo, magulu anayi oyamba amapereka maziko azogulitsa ndikuwonjezera mphamvu. Magawo anayi omaliza amakhala ngati katundu wowonjezereka, kukana kwa kutukudwa, kutchinjiriza, ndi kukhazikika kwa kapangidwe kake ka mankhwala.

1. Zosasinthika polyester nthawi zambiri zimakhala zopumira kuchokera kwa osavomerezeka acids (kapena anhydrides), zotupa za dicarboxylicylic acid (kapena anhydrides), ndi ma polydes. Ili ndi mphamvu zina ndi mphamvu, ndipo mphamvu yamkati ndi yunifolomu. Mtumiki wa mtanda amakhala ngati styrene. Awiriwo atalumikizidwa, ndi zinthu zazikulu zochirikiza pulasitiki zazomwe zimathandizira, zomwe zimakonda kulumikizana, zimathandizira, kufalitsa mosamala, ndi chitetezo.

2. Woyambitsa amayambitsa utomoni komanso wowotcha kuti azichiritsa ndikupanga mawonekedwe a prin paste phazi. Ntchito yake imakonda kupanga resin ndi kuphatikizika kawiri kolumikizira kolumikizana monga styrene kukongoletsa kotero kuti SMC ikhoza kukhala yokhazikika ndipo imapangidwa mutseke.

3. Offer amakhala ndi gawo limodzi mwa magawo atatu a pepala lowumba pawiri ndipo amatha kusintha mafayilo a pawiri. Nthawi zambiri zimafunikira kukhala ndi mawonekedwe a mphamvu yotsika, njira yochepetsetsa yamafuta, pores ochepa, kutsutsana kochepa, komanso mtengo wotsika. Zojambula zomwe zimagwiritsidwa ntchito zojambulazo zimakonda makamaka CACO3, AL (O) 3, ndi zina zotero.

4. Otsatsa okulitsa amapereka smc kukhala mafayilo apamwamba, malo osamata. Kukonzekera kwa mapepala ndi mafuta owuma kumafunikira ma vinyapo otsika a resin kuti athandizirenso kukhazikika kwa galasi ndi zosefera ndi utomoni. Ndi kutsutsana kusokoneza kumafuna ma viscty apamwamba. Chifukwa chake, ndikofunikira kuwonjezera thickener isanayambe kusintha mafayilo otsika a galasi kukweza kwa galasi lomwe silimangokhala.

5. Wogulitsa amalepheretsa kuti agule pawiri chifukwa chokhala ndi chipembedzo cholimba. Wogulitsayo amatha kuletsa polyester osakhudzidwa ndi kulumikizana ndi mawonekedwe a chitsulo nthawi ya pulasitiki yosinthira. Makamaka mafuta ochulukirapo a acids kapena mchere womwe umayimiriridwa ndi zinc Stearate. Kugwiritsa ntchito kwambiri kumachepetsa mosavuta magwiridwe antchito. Maakaunti a USGEGEGE ORGEGE KWA 1 ~ 3% yazinthu zonse kuti zitsimikizire kuti malondawo.

6. Matiberi agalasi amatha kukulitsa chipongwe ndi kutchinjiriza kwa SMC. Tsamba limawumba pawiri nthawi zambiri zimasankha masanjidwe osadulidwa a galasi kutsutsidwa ngati zinthu. Kugwiritsa ntchito kwambiri kumapangitsanso kuti malonda azitha kufopa kwambiri, komanso kugwiritsa ntchito mlingo waukulu kwambiri sudzalimbikitsa kwambiri malonda. Kugwiritsa ntchito wamba kuli pafupifupi 20%. Mwanjira imeneyi, chinthucho chimatha kukwaniritsa nthawi yomweyo njira ziwiri zokupangidwira komanso kusokoneza.

7. Ofesi ya inribetor imakulitsa kukhazikika kwa SMC ndikupitirira nthawi yosungirako. Popeza choyambitsa ilower amawola pang'onopang'ono, ndikupangitsa kuti polymerization ya utoto, kuwonjezera kuchuluka kwa radical scaronger (polymerization inroptor fromrenger (imatha kuchepetsa kuthamanga kwa styrene kuwola ndi kusungunuka nthawi yosungirako. Zilonda nthawi zambiri zimakhala benzoquinones komanso zowonjezera za polyvalelic.

Kugwiritsa ntchito mapepala opanga zogulitsa

SMC ili ndi zabwino zamagetsi zamagetsi, kukana kwamphamvu, zopepuka, zopepuka komanso zosinthika, zosinthasintha komanso zofananira zake ndizofanana ndi zitsulo zina. Chifukwa chake, imagwiritsidwa ntchito kwambiri m'minda isanu ndi itatu monga mafakitale ogulitsa magalimoto, magalimoto a sitima, zomangamanga, zida zamagetsi, komanso zokambirana (tebulo 1).

Pakati pawo, kumayambiriro, amagwiritsidwa ntchito makamaka ngati mabodi ogwiritsira ntchito mu minda yomanga, zida zamagetsi, ndi kulumikizana, ndipo ukadaulo umakhwima. Kenako idagwiritsidwa ntchito mu mafakitale agalimoto kuti ilowe m'malo mwa zinthu zachitsulo ndi aluminium za thupi kuti muchepetse kulemera kwa galimoto.

Mothandizidwa ndi kutsika kwa mphamvu ndi kusintha kwa magalimoto atsopano, ukadaulo wa zinthu zamagalimoto umapitilirabe kufika pa zopepuka komanso zapamwamba kwambiri. Mpaka pano, kugwiritsa ntchito zida za SMC kumatha kuwoneka paliponse pamoyo watsiku ndi tsiku. Zimawonetsedwa mu zolumikizana zopanda zingwe, zophulika zamagetsi zophulika, zida zotchinga pansi, zimbudzi, mabafa, ndi malo othamanga othamanga.

Mautuwa osakhudzidwa polyester, wothandizira, woyambitsa, komanso wolumbira mu pepala lowumba amapanga zida zopangira zinthu ndikuwonjezera mphamvu. Thickener, kumasula wothandizira, fiberi galasi, ndi polymerization inrobitor, kukana, kusokonezeka, komanso kukhazikika kwa zinthuzo. Zinthu ngati zoterezi zagwiritsidwa ntchito m'minda yayikulu isanu ndi itatu kuphatikiza mafakitale agalimoto ndi magalimoto a njanji. Pansi pa Kuyambira kwamphamvu kusungidwa kwa mphamvu, kutetezedwa kwa chilengedwe, komanso kugwiritsa ntchito mphamvu zochepa, makampani ogulitsa amaika patsogolo kwambiri ndi zofunika kwambiri kwa zinthu za SMC chifukwa cha zopepuka zawo. Yomwe ndi mphamvu yayikulu yoyendetsa ukadaulo wa SMC.
