Ukuhlanganiswa kwerabha yisayensi esisiseko kunye netekhnoloji yokuguqula ii-elastomers eziluhlaza zibe zizinto ezisebenzisekayo ezineempawu ezichanekileyo. Kubandakanya ukukhetha nokudibanisa iipolymers zerabha—zombini zendalo nezenziweyo—kunye noluhlu olulinganisiweyo lwezongezo ukuze kufezekiswe iimpawu ezithile zokusebenza ezifana nokuthamba, ubulukhuni, ukumelana nokukrweleka, ukumelana nobushushu, kunye nokuzinza kweekhemikhali. Eli nqaku libonelela ngesishwankathelo sokuhlelwa kwezithako zokuhlanganiswa kwerabha, ukusetyenziswa okuphambili kwee-compounds zerabha, kunye nezixhobo ezibalulekileyo ezisetyenziswa kwinkqubo yokuxuba.
Uhlu lweZithako eziDibanisayo
Izithako ezikwi-rubber compound zingahlulwahlulwa ngokweenkqubo zibe ziindidi ezahlukeneyo ezisebenzayo:
1. Ii-Elastomers (iiPolymers ezisisiseko): Inxalenye ephambili, edla ngokulinganiswa njengeenxalenye ezili-100 ngerabha nganye ngekhulu (phr). Oku kuquka irabha yendalo (NR)—evela kwi-latex yomthi weHevea, enika amandla okutsala kunye nokumelana nokukrazuka okuphezulu—kunye noluhlu olubanzi lweerabha ezenziweyo ezifana nerabha yestyrene-butadiene (SBR), ipolybutadiene (BR), i-ethylene-propylene-diene monomer (EPDM), irabha ye-nitrile (NBR), kunye nee-elastomers ezikhethekileyo ezifana ne-silicone kunye ne-fluoroelastomers.
2. Inkqubo yokudibanisa (yokuKhanyisa): Oku kuquka izinto ezibangela ukubola ezifana nesalfure (0.5–35 phr), ii-accelerators (0.5–5 phr), kunye nee-activators ezifana ne-zinc oxide (1.0–5 phr). Le nkqubo idala ii-crosslinks zeekhemikhali eziguqula irabha eluhlaza ye-thermoplastic ibe yi-thermoset material eneempawu ezihlala ixesha elide.
3. Izizalisi: Zahlulwe zibe zizizalisi zokuqinisa (umz., umnyama wekhabhoni kunye nesilika) ezomeleza amandla oomatshini, ukumelana nokukrweleka, kunye nokumelana nokukrazuka, kunye nezizalisi ezingaqinisiyo okanye ezolulayo (umz., udongwe, icalcium carbonate, i-mica) ezisetyenziselwa ukunciphisa iindleko kunye nokulawula ubukhulu. Umthwalo wezalisi ungahluka ukusuka kwi-25 ukuya kwi-200 phr.
4. Iiplastiki kunye neZithambisi: Zongezwa ukuphucula ukucutshungulwa, ukunciphisa ukuxinana, kunye nokuphucula ukuguquguquka kobushushu obuphantsi.
5. Izinto ezithintela ukubola: Izinto ezithintela ukubola kunye nezinto ezithintela ukubola (0.5–2 phr) ezikhusela i-compound ekuwohlokeni kwe-oxidative kunye ne-ozone.
6. Izixhobo Zokucubungula: Kubandakanya iipeptizer, ii-tackifiers, kunye nezinye izinto ezenza kube lula ukuxuba nokwenza imisebenzi.
Iinkqubo zokuxuba kunye nezixhobo
Ukudibanisa irabha kufuna izixhobo ezikhethekileyo ukuze kufezekiswe ukuhlanganiswa okufanayo kunye nokusasazwa kwazo zonke izithako kwi-matrix ye-elastomeric. Iindlela ezisetyenziswa kakhulu kushishino lwerabha ziinkqubo zokuxuba iibhetshi.
IiMixers Zangaphakathi (iiBanbury Mixers): Ezi ziindlela zokusebenza zerabha zanamhlanje. I-mixer yangaphakathi inee-rotors ezimbini ezijikelezayo ezifakwe kwigumbi lokuxuba elivaliweyo. Iindidi ezimbini zee-rotors zisetyenziswa rhoqo: ii-rotors ezi-tangential, eziqala zisasazeke emva koko zisasaze izinto, kunye nee-rotors ezidibanisayo, ezisebenza ngokulandelelana okwahlukileyo. Ii-mixers zangaphakathi zisebenza phantsi kobushushu obulawulwayo kunye noxinzelelo, zibonelela ngokusebenza kakuhle, ukusasazwa okufanayo, kunye nokunciphisa ungcoliseko lokusingqongileyo. Zibalulekile ekwenziweni kwamatayara kunye nemveliso yerabha yemizi-mveliso emikhulu.
IiMill ezineeRoll ezimbini (iiOpen Mills): Ezi ziquka iirola ezimbini ezifakwe ngokuthe tye, ezijikelezayo. I-compound yerabha idluliselwa ngokuphindaphindiweyo nge-nip phakathi kweerola, apho amandla aphezulu okucheba akhuthaza ukuxuba nokusasazwa. Ii-mill ezineerola ezimbini zisetyenziselwa ukwenza irabha yendalo ibe yiplastiki, ukuxuba iikhompawundi, ukufudumeza isitokhwe, kunye nemisebenzi yokubeka amashiti. Zihlala zibalulekile kwimveliso encinci, iikhompawundi zemibala, kunye nokusetyenziswa okufuna ulawulo lobushushu olucokisekileyo.
Imijikelo Yokuxuba: Kuye kwaveliswa iindlela ezahlukeneyo zokuxuba, kuquka ukuxuba okuqhelekileyo (kongezwa irabha kuqala, kulandele iipowders, iiplasticizers, iioyile, kunye nee-curing agents), ukuxuba okujonge phantsi (izizalisi kunye neeoyile ezixutywe ngaphambi kokongeza i-polymer), ukuxuba okukwinqanaba elinye, kunye nokuxuba okukwinqanaba ezimbini (okunciphisa impembelelo yobushushu kwaye kuphucula ukusasazeka). Ukukhetha umjikelo kuxhomekeke kwifomyula ye-compound kunye neempawu ezifunwayo.
Izicelo
Iikhompawundi zerabha zibaluleke kakhulu phantse kuzo zonke iicandelo zoshishino kunye nabathengi.
Iimoto kunye nokuThutha: Eli lisese licandelo elisebenzisa kakhulu. Iikhompawundi zerabha zisetyenziswa kumatayara, kwinkqubo yomatshini wokuxuba irabha, kwiipayipi, kwiiseal, kwiigasket, kwiibhanti, kwiindawo zokufaka iinjini, ekususeni imozulu, nakwiindawo ezithintela ukungcangcazela. Ukwanda kwezithuthi zombane kuqhuba imfuno yeekhompawundi ezinokumelana nomlilo okuphuculweyo, ukugquma umbane, kunye nezakhono zokulawula ubushushu.
Ukusetyenziswa Kwemizi-mveliso: Iikhompawundi zibalulekile kwiibhanti zokuhambisa, iipayipi zemizi-mveliso, izinto ezibunjiweyo, iirola, kunye nokufakelwa kwentambo kunye nentambo. Ezi zicelo zifuna ukumelana nokugruzuka okuphezulu, uzinzo lweekhemikhali, kunye nokuqina.
Iimpahla zabathengi nezoKhethekileyo: Iikhompawundi zerabha zisetyenziswa kwizihlangu, uphahla kunye nee-geomembranes, izitywino zezixhobo, ii-gaskets, kunye neemveliso zonyango kunye nokutya.
Isiphelo
Ukudibanisa irabha luqeqesho oluntsonkothileyo oludibanisa isayensi yezinto, ifektri yokuxuba irabha evulekileyo, ubunjineli beekhemikhali, kunye netekhnoloji yokucubungula. Ngokukhetha ngononophelo kunye nokudibanisa ii-elastomers kunye neenkqubo zokongeza ezikhethiweyo—kunye nokusetyenziswa kwezixhobo ezikhethekileyo ezifana nee-mixers zangaphakathi kunye nee-two-roll mills—ii-compounders zenza izinto ezenzelwe wena ezivumela iimveliso ezininzi ezibalulekileyo kubomi banamhlanje, i-material mixing mill, ukusuka kumatayara kunye neebhanti zokuhambisa ukuya kwiiseal kunye nezixhobo zonyango.
