I-PHIPE YOKUGQIBELA I-POSTE ibhekisa kwi-Polyster engabhaliswanga i-Polyen engabhaliswanga, yongeza iarhente yokukhupha, i-ficler, i-ficler, njl. Njl. Njl. Njl.Eli phepha lichaza ngokufutshane ukwakhiwa kunye nokuhlelwa kwe-SMC.
Ukwakheka kweShiti lokuBumba
I-SMC yenziwe ngentlaka ye-polyester engaxutywanga, i-agent edibanisayo, i-initiator, i-filler, i-thickener, i-arhente yokukhulula, i-glass fiber, kunye ne-polymerization inhibitor.Phakathi kwabo, iindidi ezine zokuqala zibonelela ngokukodwa ngesakhelo sezinto eziphathekayo kwiimveliso kunye nokwandisa amandla.Iindidi ezine zokugqibela zezona zixhobo zokwanda kwe-viscosity, ukumelana nokubola, ukugquma, kunye nokuzinza kwesakhiwo semveliso.
1. I-resin ye-polyester engasetyenziswanga kunye nee-agent ezidibanisayo zingumzimba oyintloko we-SMC.I-relins ye-polyester engonwabisiyo idla ngokuvela kwi-polycoboxy evela kwi-acidsyylicy ye-acids (okanye i-anhydrides), i-Anhydrides), i-accedrides), okanye i-adhydrides), kunye nePolyols.Ineempawu ezithile zoomatshini kunye namandla, kwaye amandla angaphakathi ayafana.I-agent ye-crosslinking ikakhulu yi-styrene.Emva kokuba ezi zinto zimbini zidibene, zezona zinto ziphambili zeplasitiki yemveliso, edlala indima yonxibelelwano, inkxaso, ibhalansi yodluliselo, kunye nokukhuselwa.
2. Umqalisi ubangela ukuba i-resin kunye ne-crosslinker iphilise kwaye ifake kwinqanaba le-resin paste.Umsebenzi wayo ikakhulu ukwenza i-resin kunye ne-double bond kwi-monomer edibanisayo edibeneyo njenge-styrene copolymerize ukwenzela ukuba i-SMC iqiniswe kwaye yenziwe kwi-mold cavity.
3. I-filler ithatha ngaphezu kweyesithathu ye-sheet molding compound kwaye inokulungelelanisa i-viscosity ye-compound molding.Ngokuqhelekileyo kufuneka ukuba ube neempawu zomxhuzulane ophantsi, ixabiso le-odsortion yeoyile ephantsi, i-pores ezimbalwa, ukumelana nokunyanzelwa, kunye neendleko eziphantsi.Amacandelo asetyenziswa ngokuqhelekileyo asetyenziswa ikakhulu yiCaCO3, Al(OH)3, njalo njalo.
4. I-Thickeners inika i-SMC i-viscosity ephezulu, ipropati engancangathi.Ukulungiswa kwephepha kunye neendlela zokubumba okuxhaphakileyo zifuna i-vission ephantsi ye-resin ukulungiselela ukungena kwi-fiber yeglasi kunye nefilitha nge-resin.Kunye ne-conbunces ebunjiweyo ifuna i-viscofity ephezulu.Ke ngoko, kuyimfuneko ukongeza i-thickener ngaphambi kwenkqubo yokubumba ukuze iguqule i-viscofity esezantsi ye-fiber engakhange ifumane intetho ephezulu enganamathinga.
5. I-arhente yokukhulula ikhusela i-sheet molding compound ekubeni ibe nobudlelwane kunye ne-metal mold surface.I-arhente yokukhululwa inokuthintela i-resin ye-polyester engaxutywanga ekusebenzisaneni nomphezulu we-mold yensimbi ngexesha lenkqubo yeplastiki yomxube we-resin.Ikakhulu i-long-chain fatty acids okanye iityuwa ezimelwe yi-zinc stearate.Ukusetyenziswa kakhulu kuya kunciphisa ngokulula ukusebenza kwemveliso.Iiakhawunti zokuSetyenziswa ngokuBanzi kwi-1 ~ 3% yemveliso iyonke yokuqinisekisa ukuba umgangatho wemveliso.
6. Iifiber zeglasi zinokuphucula ukuxhathisa ukubola kunye neempawu zokugquma kwe-SMC.Ikhompawundi yokubumba amashiti idla ngokukhetha iimethi zefiber zeglasi ezinqunqiweyo njengemathiriyeli yokuqinisa.Ukusetyenziswa kakhulu kuyakwenza ukuba imveliso inomkhuhlane, kwaye ukusetyenziswa kwedosi encinci kakhulu akuyi kuba nefuthe elibonakalayo esongezelelekileyo kwimveliso.Ukusetyenziswa ngokubanzi malunga ne-20%.Ngale ndlela, imveliso inokuhlangabezana ngaxeshanye neenkqubo ezimbini zokubumba i-extrusion kunye nokubunjwa koxinzelelo.
7. I-inhibitor yandisa ukuzinza kwe-SMC kwaye yandisa ixesha lokugcina.Kuba isitayile somqalisi siya kukubola kancinci, sibangela ipolishition ye-resen, ukongeza isixa esifanelekileyo se-scavenger ye-scavenger (i-polymerication ye-ralymerical) inokucothisa isantya se-styrene kwaye sise ixesha lokugcina.Ii-inhibitors zidla ngokuba yi-benzoquinones kunye ne-polyvalent phenolic compounds.
Ukusetyenziswa kwePhepha lokuBumba iMveliso eDityanisiweyo
I-SMC ineenzuzo zokusebenza kombane okugqwesileyo, ukuxhathisa okuqinileyo kwe-corrosion, ukukhanya, kulula kunye noyilo lobunjineli obuguquguqukayo, njl njlKe ngoko, isetyenziswa kakhulu kumasimi asibhozo anje ngeshishini lemoto, izithuthi zikaloliwe, ulwakhiwo, izixhobo zombane kunye nonxibelelwano (Itheyibhile 1).
Phakathi kwazo, ekuqaleni kwenqanaba, yayisetyenziswa ikakhulu ngohlobo lweebhodi zokufaka izilwanyana kwicandelo lolwakhiwo, izixhobo zombane, kunye netekhnoloji, kunye netekhnoloji, kwaye itekhnoloji ivuthiwe.Isetyenziswe ngelo xesha kwishishini lemoto ukuba lithathe indawo yenxalenye yezixhobo zentsimbi kunye ne-aluminium ye-alloy yomzimba ukunciphisa ubunzima bemoto.
Ngaphantsi kwemvelaphi yogcino lwamandla lwangoku kunye nokunciphisa ukukhutshwa kunye nokuphuhliswa kwezithuthi zamandla amatsha, iteknoloji yeemveliso zemoto iyaqhubeka nokuphuhlisa ngokubhekiselele ekukhanyeni kunye nomgangatho ophezulu.Ukuza kuthi ga ngoku, ukusetyenziswa kwezixhobo ze-SMC kunokubonwa kuyo yonke indawo kubomi bemihla ngemihla.Iboniswa kunxibelelwano olungenazingcingo, ukuqhuma - izinto ezifihlakeleyo zombane, izixhobo zokufakwa komhlaba, amagumbi okuhlambela, kunye nezixhobo ezihamba ngesantya esiphezulu.
