Ishiti lokubumba ikhompawundi libhekisela kwintlaka yepolyester engaxutywanga njengowona mzimba uphambili, ukongeza i-ejenti yokunyanga, i-ejenti yokukhulula umngundo, i-filler, i-agent ephantsi yokunciphisa, i-thickener, 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-resins ye-polyester engaxutywanga i-polycondensed ukusuka kwi-unsaturated dicarboxylic acids (okanye i-anhydrides), i-dicarboxylic acids egcweleyo (okanye i-anhydrides), kunye ne-polyols.Ineempawu ezithile zoomatshini kunye namandla, kwaye amandla angaphakathi ayafana.I-agent ye-crosslinking ikakhulu yi-styrene.Emva kokuba ezi zimbini zidibaniswe, zizona zixhobo eziphambili zokuphilisa iplastiki yemveliso, edlala indima yokudibanisa, inkxaso, ibhalansi yokudlulisa kunye nokukhusela.
2. Umqalisi ubangela ukuba i-resin kunye ne-crosslinker iphilise kwaye ifake kwinqanaba le-resin paste.Umsebenzi walo ikakhulu ukwenza i-resin kunye ne-double bond kwi-cross-linking monomer efana ne-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 ibe neempawu zobunzima obuthile obuphantsi, ixabiso le-oyile ye-adsorption ephantsi, ii-pores ezimbalwa, ukuxhathisa ukubola, kunye nexabiso eliphantsi.Amacandelo asetyenziswa ngokuqhelekileyo asetyenziswa ikakhulu yiCaCO3, Al(OH)3, njalo njalo.
4. I-Thickeners inika i-SMC i-viscosity ephezulu, ipropati engancangathi.Ukulungiswa kwamaphepha kunye neengqungquthela zokubumba ezininzi kufuna i-viscosity ephantsi ye-resin ukuququzelela ukufakwa kwe-fiber yeglasi kunye nokuzaliswa nge-resin.Kwaye ukubunjwa koxinzelelo kufuna i-viscosity ephezulu.Ngoko ke, kuyimfuneko yokongeza i-thickener phambi kwenkqubo yokubumba ukuguqula i-viscosity ephantsi ye-glass fibre impregnation ibe yi-viscosity ephezulu engabambekiyo.
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 ngokugqithiseleyo kuya kunciphisa ngokulula ukusebenza kwemveliso.Ukusetyenziswa ngokubanzi kubala i-1 ~ 3% yemveliso epheleleyo ukuqinisekisa 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 ngokugqithiseleyo kuya kwenza ukuba imveliso ibe lula kakhulu, kwaye ukusetyenziswa kwedosi encinci akuyi kuba nomphumo ocacileyo wokuqiniswa 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.Ekubeni i-initiator styrene iya kubola ngokukhawuleza, ibangela i-polymerization ye-resin, yongeza inani elifanelekileyo le-free radical scavenger (i-polymerization inhibitor) inokucothisa isantya sokubola kwe-styrene kunye nokwandisa ixesha lokugcinwa kwayo.Ii-inhibitors zidla ngokuba yi-benzoquinones kunye ne-polyvalent phenolic compounds.
Ukusetyenziswa kweeMveliso zoMdibaniso wePhepha lokuBumba
I-SMC ineenzuzo zokusebenza kombane okugqwesileyo, ukuxhathisa okuqinileyo kwe-corrosion, ukukhanya, kulula kunye noyilo lobunjineli obuthambileyo, njl.Ke ngoko, isetyenziswa kakhulu kumacandelo asibhozo anje ngeshishini leemoto, izithuthi zikaloliwe, ulwakhiwo, izixhobo zombane kunye nonxibelelwano (Itheyibhile 1).
Phakathi kwabo, kwisigaba sokuqala, yayisetyenziswa ikakhulu ngendlela yeebhodi zokugquma kwiindawo zokwakha, izixhobo zombane kunye nonxibelelwano, kwaye iteknoloji ikhulile.Yathi ke isetyenziswe kushishino lweemoto ukubuyisela inxalenye yentsimbi kunye ne-aluminium alloy izinto zomzimba 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.Ibonakala kunxibelelwano olungenazingcingo, kwiindawo ezivaliweyo zombane ezingagqabhukiyo, izixhobo zokugquma umhlaba, amagumbi okuhlambela, kunye noncedo lukaloliwe oluhamba ngesantya esiphezulu.
