iindaba

Ii-phenolic molding compounds zizinto zokubumba ezisebenzisa i-thermosetting ezenziwe ngokuxuba, ukuxova, kunye ne-granulating phenolic resin njenge-matrix enezihluzi (ezifana nomgubo womthi, i-glass fiber, kunye ne-mineral powder), ii-curing agents, ii-lubricants, kunye nezinye izongezo. Iingenelo zazo eziphambili zikwimeko entle yokumelana nobushushu obuphezulu (ubushushu bokusebenza ixesha elide ukuya kuthi ga kwi-150-200℃), iipropati zokukhusela (ukumelana nomthamo ophezulu, ukulahleka kwe-dielectric ephantsi), amandla oomatshini, kunye nokuzinza kobukhulu. Zikwamelana nokugqwala kweekhemikhali, zineendleko ezilawulekayo, kwaye zigcina ukusebenza okuzinzileyo naphantsi kobushushu obuphezulu, i-voltage ephezulu, okanye iindawo ezifumileyo.

Iintlobo zeIikhompawundi zokubumba zePhenolic 

Iikhompawundi zokubumba ucinezelo:Ezi zifuna ukubumba okucinezelweyo. Izinto ezisetyenzisiweyo zifakwa kwisikhunta zize zinyangwe phantsi kobushushu obuphezulu kunye noxinzelelo (ngesiqhelo i-150-180℃ kunye ne-10-50MPa). Zifanelekile ukuvelisa iimilo ezintsonkothileyo, iimfuno zokuchaneka okuphezulu, okanye iindawo ezinkulu, ezinodonga oluqinileyo, ezifana nezixhobo zokukhusela ubushushu kwizixhobo zombane kunye nezixhobo ezimelana nobushushu ezijikeleze iinjini zeemoto. Ngokusasazeka kwezalisa ezifanayo, iimveliso zibonisa amandla aphezulu oomatshini kunye nokumelana nobushushu obuphezulu, nto leyo eyenza ukuba zisetyenziswe kakhulu kwiindawo zoshishino eziphakathi ukuya kweziphezulu kunye nohlobo lwemveliso eqhelekileyo.

Iikhompawundi zokubumba ngenaliti:Zifanelekile kwiinkqubo zokubumba ngenaliti, ezi zinto zinokuhamba kakuhle kwaye zinokuzaliswa ngokukhawuleza kwaye zinyangwe kwiimashini zokubumba ngenaliti, nto leyo ekhokelela ekusebenzeni kakuhle kwemveliso kunye nokuzisebenzela ngokuzenzekelayo. Zifanelekile kwimveliso enkulu yezinto ezincinci ukuya kweziphakathi, ezakhiwe ngendlela eqhelekileyo, ezifana neepaneli zokutshintsha izixhobo zasekhaya, izihlanganisi ze-elektroniki zeemoto, kunye neendawo ezincinci zokufakelwa umbane. Ngokuthandwa kweenkqubo zokubumba ngenaliti kunye nokwenza ngcono ukuhamba kwezinto, isabelo semarike sale mveliso sikhula kancinci kancinci, ngakumbi njengoko zihlangabezana neemfuno ezinkulu zemveliso yeemveliso zabathengi.

Iindawo zokusetyenziswaIikhompawundi zokubumba zePhenolic

Izixhobo zoMbane/ze-Elektroniki:Le yimeko yesicelo esiphambili, egubungela izinto zokwambathisa kunye neendawo zesakhiwo sezixhobo ezifana neemoto, iitransformer, ii-circuit breakers, kunye nee-relay, ezifana nee-motor commutators, ii-transformer insulation frames, kunye nee-circuit breaker terminals. Ukwambathisa okuphezulu kunye nokumelana nobushushu obuphezulu kwee-phenolic molding compounds kuqinisekisa ukusebenza ngokukhuselekileyo kwezixhobo zombane phantsi kweemeko zombane ophezulu kunye nobushushu obuphezulu, okuthintela ii-short circuits ezibangelwa kukungasebenzi kakuhle kwe-insulation. Ii-compounds ze-compression molding zisetyenziswa kakhulu kwiindawo ezibalulekileyo ze-insulation, ngelixa ii-compounds ze-injection molding zifanelekile kwimveliso enkulu yezixhobo ezincinci ze-elektroniki.

Ishishini leeMoto:Isetyenziselwa izinto ezimelana nobushushu kwiinjini zeemoto, iinkqubo zombane, kunye ne-chassis, ezifana nee-gaskets zentloko yesilinda yenjini, iindawo zokugcina ii-ignition coil, ii-sensor brackets, kunye nezinto zenkqubo yokubhuleka. Ezi zinto kufuneka zimelane nobushushu obuphezulu bexesha elide benjini (120-180℃) kunye nefuthe lokungcangcazela. Ii-phenolic molding compounds ziyahlangabezana nezi mfuno ngenxa yokumelana kwazo nobushushu obuphezulu, ukumelana neoyile, kunye namandla oomatshini. Zikhaphukhaphu kunezixhobo zesinyithi, zinegalelo ekunciphiseni ubunzima kunye nokusebenza kakuhle kwepetroli kwiimoto. Ii-compounds zokubumba ezixineneyo zifanelekile kwizinto ezimelana nobushushu ezijikeleze injini, ngelixa ii-compounds zokubumba ezifakelweyo zisetyenziselwa izinto zombane ezincinci neziphakathi.

Izixhobo zasekhaya:Ifanelekile kwizinto ezisebenza kakuhle nezimelana nobushushu kwizixhobo ezifana nezipheki zerayisi, ii-oveni, ii-oveni ze-microwave, kunye noomatshini bokuhlamba, njengezixhobo zokuxhasa imbiza yangaphakathi ye-rice cooker, izixhobo zokufudumeza i-oveni, izixhobo zokuvala ucango lwe-oveni ye-microwave, kunye nezigqubuthelo ze-motor yomatshini wokuhlamba. Izixhobo zezixhobo kufuneka zimelane nobushushu obuphakathi ukuya kobuphezulu (80-150℃) kunye neendawo ezifumileyo ngexesha lokusetyenziswa kwemihla ngemihla.Iikhompawundi zokubumba zePhenolicIingenelo ezibalulekileyo ekumelaneni nobushushu obuphezulu, ukuxhathisa ukufuma, kunye nexabiso eliphantsi. Iikhompawundi zokubumba ngenaliti, ngenxa yokusebenza kwazo kakuhle kwemveliso, ziye zaba lukhetho oluphambili kwishishini lezixhobo zasekhaya.

Ezinye izicelo ziquka i-aerospace (ezifana nezixhobo ezincinci zokukhusela umoya kwizixhobo eziqhutywa emoyeni), izixhobo zonyango (ezifana nezixhobo zokubulala iintsholongwane kwiqondo lobushushu eliphezulu), kunye neevalvu zemizi-mveliso (ezifana nezitulo zokuvala iivalvu). Umzekelo, iitreyi zokubulala iintsholongwane kwiqondo lobushushu eliphezulu kwizixhobo zonyango kufuneka zimelane nokuvalwa kweentsholongwane ngomphunga kwi-121°C, kwaye ii-phenolic molding compounds zinokuhlangabezana neemfuno zokumelana nobushushu kunye nococeko; izitulo zokuvala iivalvu zemizi-mveliso kufuneka zingabi nangxaki yokugqwala kunye namaqondo obushushu athile, nto leyo ebonisa ukuba ziyaziqhelanisa neemeko ezahlukeneyo.
