Iikhompawundi zokubumba zePhenoliczahlulwe zibe ziintlobo ezimbini ngokusekelwe kumahluko kwiinkqubo zokwakha:

IiCompounds zokubumba ngokucinezelwa: Zicutshungulwa ngokubumba ngokucinezelwa, apho izinto zifakwa kwisikhunta kwaye zifakwe kubushushu obuphezulu kunye noxinzelelo (ngesiqhelo i-150-180°C, i-10-50 MPa) ukuze zifumane ukuphiliswa. Zifanelekile ukuvelisa iimilo ezintsonkothileyo, izinto ezifuna ukuchaneka okuphezulu, okanye iindawo ezinkulu ezixineneyo ezifana nezibiyeli zokufaka ubushushu kwizixhobo zombane kunye nezinto ezimelana nobushushu ezijikeleze iinjini zeemoto. Ngokusasazeka kwezalisa ezifanayo, ezi zibonelela ngamandla aphezulu oomatshini kunye nokumelana nobushushu obuphezulu. Zisetyenziswa kakhulu kwiindawo zoshishino eziphakathi ukuya kweziphezulu kwaye zimele uhlobo lwemveliso eqhelekileyo.

Iikhompawundi zokubumba ngenaliti: Zenzelwe iinkqubo zokubumba ngenaliti, ezi zinto zibonisa iimpawu zokuhamba kakuhle. Zizalisa ngokukhawuleza iimolds kwaye zinyangeke ngoomatshini bokubumba ngenaliti, zibonelela ngempumelelo ephezulu yemveliso kunye nokuzisebenzela ngokuzenzekelayo. Zilungele ukuvelisa izinto ezincinci ukuya kweziphakathi ezinobukhulu obuqhelekileyo, ezifana neepaneli zokutshintsha izixhobo zasekhaya, izihlanganisi ze-elektroniki zeemoto, kunye nezithinteli zombane ezincinci. Ngokwamkelwa ngokubanzi kwe-injection molding kunye nokuhamba kakuhle kwezinto, isabelo semarike sale mveliso sikhula ngokuthe chu, ngakumbi ukuhlangabezana neemfuno zemveliso ezilinganisiweyo zeempahla zabathengi.

IiDomain zeSicelo: Iimeko zoPhuculo oluPhambili zeIikhompawundi zokubumba zePhenolic

Ukusetyenziswa kwee-phenolic molding compounds kugxile kakhulu kwimveliso yemizi-mveliso, zahlulwe zibe ngamacandelo amane ahlukeneyo:

Izixhobo zoMbane/ze-Elektroniki: Indawo esetyenziswa kakhulu iquka izinto zokwambathisa kunye nezolwakhiwo lweemoto, iitransformer, ii-circuit breakers, ii-relay, kunye nezixhobo ezifanayo. Imizekelo ibandakanya ii-motor commutators, ii-transformer insulating cores, kunye nee-terminals ze-circuit breaker. Ukwambathisa okuphezulu kunye nokumelana nobushushu kweeplastiki ezibunjiweyo ze-phenolic kuqinisekisa ukusebenza ngokukhuselekileyo kwezixhobo zombane phantsi kweemeko ze-voltage ephezulu kunye nobushushu obuphezulu, okuthintela ii-short circuits ezibangelwa kukungasebenzi kakuhle kwe-insulation. Iiplastiki ezibunjiweyo ezixineneyo zisetyenziselwa ikakhulu izinto zokwambathisa ezibalulekileyo, ngelixa iiplastiki ezibunjiweyo ezifakwe injection zilungele ukuveliswa ngobuninzi kwezinto ezincinci ze-elektroniki.

Ishishini leeMoto: Lisetyenziswa kwizinto ezimelana nobushushu kwii-peripherals zenjini yemoto, iinkqubo zombane, kunye ne-chassis, ezifana nee-gaskets zentloko yesilinda yenjini, iindawo zokugcina ii-ignition coil, ii-sensor brackets, kunye nezinto zenkqubo yeebhuleki. Ezi zinto kufuneka zinyamezele ukuvezwa ixesha elide kumaqondo obushushu enjini (120-180°C) kunye nokungcangcazela/impembelelo. Iiplastiki ezibunjiweyo ze-phenolic ziyahlangabezana neemfuno zokumelana kwazo nobushushu obuphezulu, ukumelana neoyile, kunye namandla oomatshini, ngelixa zinika ubunzima obulula kuneentsimbi ukunciphisa ubunzima besithuthi kunye nokusetyenziswa kwepetroli. Iiplastiki ezibunjiweyo ezicinezelweyo zifanela izinto zenjini ezimelana nobushushu, ngelixa iiplastiki ezibunjiweyo ezifakwe injection zisetyenziselwa iindawo zombane ezincinci ukuya kweziphakathi.

Izixhobo Zasekhaya: Zifanelekile kwizixhobo ezisebenza kakuhle nezikwaziyo ukumelana nobushushu kwizixhobo ezifana nezipheki zerayisi, ii-oveni zombane, ii-microwave, kunye noomatshini bokuhlamba. Imizekelo ibandakanya izibiyeli zembiza zangaphakathi ze-rice cooker, izixhobo zokufudumeza i-oven zombane, iindawo zokuvala ucango lwe-microwave, kunye nezigqubuthelo ze-motor end ze-washing machine. Izixhobo zezixhobo kufuneka zinyamezele amaqondo obushushu aphakathi ukuya kwaphezulu (80-150°C) kunye neendawo ezifumileyo ngexesha lokusetyenziswa kwemihla ngemihla. Iiplastiki ezibunjiweyo ze-phenolic zibonelela ngeenzuzo ezibalulekileyo ekuchaseni amaqondo obushushu aphezulu, ukuchasana nokufuma, kunye nokusebenza kakuhle kweendleko. Iiplastiki ezibunjiweyo ngenaliti, ngenxa yokusebenza kwazo kakuhle kwimveliso, ziye zaba lukhetho oluphambili kwicandelo lezixhobo zasekhaya.

Ezinye izicelo:Iiplastiki ezibunjwe ngephenoliczikwasetyenziswa nakwi-aerospace (umz., iindawo ezincinci zokukhusela izixhobo ezikwibhodi), izixhobo zonyango (umz., izixhobo zokubulala iintsholongwane ezishushu kakhulu), kunye neevalvu zoshishino (umz., izihlalo zevalvu zokutywina). Umzekelo, iitreyi zokubulala iintsholongwane ezishushu kakhulu kwizixhobo zonyango kufuneka zimelane nokubulala iintsholongwane ngomphunga oxinzelelo oluphezulu lwe-121°C, apho iiplastiki ezibunjiweyo ze-phenolic zihlangabezana neemfuno zokumelana nobushushu kunye nococeko. Izitywino zezihlalo zeevalvu zoshishino zifuna ukumelana nokugqwala kwemidiya kunye nobushushu obuthile, nto leyo ebonisa ukuba ziyaguquguquka kuzo zonke izicelo ezahlukeneyo.
