Ukuqulunqwa kunye nokusetyenziswa kwemephu yeshiti

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 ikakhulu lichaza ngokufutshane ukwakhiwa kunye nokusetyenziswa kwe-SMC.

Iphepha lokwakhiwa kwephepha

I-SMC iqulathe i-Polyester eNgeyo, iarhente enqamlezileyo, i-itiator, ifiliter, i-thicker, i-fiber yokukhupha, kunye ne-fiber ye-fiber, kunye ne-fiber ye-fiber, kunye ne-fiber ye-fiber. Phakathi kwazo, iindidi ezine zokuqala zibonelela ngesakhelo semveliso kunye nokonyusa amandla. Iindidi ezine zokugqibela ikakhulu zenzelwe ipropathi yothintelo olwandisiweyo, ukuxhathisa i-corrosion, i-insulser, kunye nokuzinza kwemveliso.

I-1. I-Polyester engadibaniyo kunye neearhente ezinqamlezileyo zezona mzimbeni ziphambili zeSMC. 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 nePolydols. Inepropathi ethile yoomatshini kunye namandla, kwaye amandla angaphakathi afanayo. Iarhente enqamlezileyo ikakhulu ityhefu. Emva kokuba ezi zinto zimbini zidibene, zezona zinto ziphambili zeplasitiki yemveliso, edlala indima yonxibelelwano, inkxaso, ibhalansi yodluliselo, kunye nokukhuselwa.

2. Umqalisi ubangela i-resin kunye ne-rocklinker yokunyanga kunye nefom kwindawo yePasika. Umsebenzi wayo ikakhulu ukwenza i-resin kunye nebhondi ephindwe kabini kwi-monomer egcobileyo njenge-styrene copolymerize ukwenzela ukuba i-SMC inokuqiniswa kwaye yenziwa kwi-smc cavity.

3. I-filler ihlala ngaphezulu kwesinye kwisithathu sephepha lokubumba kwaye linokulungelelanisa i-viscofity yecandelo lemibumba. Ngokuqhelekileyo kufuneka ukuba ube neempawu zomxhuzulane ophantsi, ixabiso le-odsortion yeoyile ephantsi, i-pores ezimbalwa, ukumelana nokunyanzelwa, kunye neendleko eziphantsi. Izinto eziqhelekileyo ezisetyenziswa ikakhulu zii-caco3, al (O) 3, njalo njalo.

I-4. Amantshontsho anika i-SMC viscofity ephezulu, ipropathi enganamathela. 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. Iarhente yokukhutshwa ithintele i-Sheet ibumba i-computer ivele ukuba i-fackinity yomphezulu wentsimbi. Iarhente yokukhutshwa inokuthintela i-polyerter engacwangciswanga iphinde isebenze ngokunxibelelana nomphezulu wesinyithi ngexesha lenkqubo yeplastiki yomxube we-resin. Ubukhulu becala i-chain enamafutha amanqatha okanye iityuwa ezimelwe yi-zinc steate. Ukusetyenziswa kakhulu kuya kunciphisa ngokulula ukusebenza kwemveliso. Iiakhawunti zokuSetyenziswa ngokuBanzi kwi-1 ~ 3% yemveliso iyonke yokuqinisekisa ukuba umgangatho wemveliso.

I-6. Iintsinga zeglasi zingaphucula ukuxhathisa i-corrosion kunye nepropathi ye-SMC. Iphepha lokubumba le-Sheet lihlala likhetha i-mats ekhethiweyo ye-fiber ye-fiber njengezinto zokuqinisekisa. 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 inokwama ngaxeshanye ihlangabezane neenkqubo ezimbini zokupheliswa kokubumba kunye nokubumba.

I-7. I-inhibitor yonyusa uzinzo lwe-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. I-inhibitors ihlala i-Benzoquinones kunye ne-polyvaterals computers.

Ukusetyenziswa kwemveliso ye-GARD

I-SMC ineengenelo zokusebenza kombane, ukunganyangeki okuqinileyo, ilula kunye nokuyilwa komthombo wobunjineli kunye nokuguquguquka kobuchwephesha, njl. Njl. Ke ngoko, isetyenziswa ngokubanzi kumacandelo asibhozo anjengeshishini lemoto, izithuthi zikaloliwe, ukwakhiwa, 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 yolondolozo lwamandla ngoku kunye nokuphuhliswa kwezithuthi zamandla amatsha, itekhnoloji yeemveliso zemoto ziyaqhubeka nokukhula kwinqanaba eliphezulu 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.

Itheyibhile 1 Izicelo eziphambili zezinto ezikhulu kunye neendawo zokwahlulahlula izinto zeSMC

Shwankathela

I-Polyester engadibaniyo, iarhente enqamlezileyo, i-itimutor, kunye ne-filler kwiphepha lokubumba lephepha lokuzibamba libonelela ngenkqubo yemveliso yemveliso kwaye yonyuse amandla olwakhiwo. I-thickener, iarhente yokukhupha, i-fiber yeglasi, kunye ne-polymermerication inhibitor yongeza i-viscosity, ukuxhathisa i-scodison, ukufakelwa, kunye nokuzinza kwemveliso. Iimveliso ezinjalo zifakiwe kwiinkalo ezisibhozo eziphambili kubandakanya neshishini lemoto kunye nezithuthi zikaloliwe. Phantsi kwemvelaphi yangoku yolondolozo lwamandla, ukhuseleko lwendalo, kunye nokusetyenziswa kwamandla okusebenza, ishishini le-automotive libeke phambili iimfuno eziphezulu nezingaphezulu kwezinto zeSMC ngenxa yeemfuno zabo zeSCC. Nguwuphi owona mkhosi uphambili wokuqhuba kuphuhliso lwetekhnoloji ye-SMC.
