iindaba

I-Phenolic molding compounds zizinto zokubumba ze-thermosetting ezenziwe ngokuxuba, ukuxubha, kunye ne-granulating phenolic resin njenge-matrix enezihluzi (ezifana nomgubo womthi, i-glass fiber, kunye ne-mineral powder), i-agent ephilisayo, i-lubricants, kunye nezinye izongezo. Iinzuzo zabo eziphambili zilele ekuxhathiseni ubushushu obuphezulu (ubushushu bokusebenza ixesha elide ukuya kuthi ga kwi-150-200 ℃), iipropathi zokugquma (umthamo ophezulu wokuxhathisa, ukulahleka kwe-dielectric ephantsi), amandla omatshini, kunye nokuzinza komda. Kananjalo ziyakwazi ukumelana nokubola kweekhemikhali, zineendleko ezilawulekayo, kwaye zigcina ukusebenza okuzinzile naphantsi kobushushu obuphezulu, amandla ombane aphezulu, okanye iindawo ezifumileyo.

Iintlobo zePhenolic Molding Compounds 

IiCompression Molding Compounds:Ezi zifuna ukubunjwa koxinzelelo. Izinto eziphathekayo zifakwe kwi-mold kwaye zinyangelwe phantsi kobushushu obuphezulu kunye noxinzelelo (ngokuqhelekileyo i-150-180 ℃ kunye ne-10-50MPa). Zikulungele ukwenza iimilo ezintsonkothileyo, iimfuno zokuchaneka komgangatho ophezulu, okanye iindawo ezinkulu ezinodonga olungqingqwa, njengezixhasi zokugquma kwizixhobo zombane kunye nezinto ezikwaziyo ukumelana nobushushu ezijikeleze iinjini zeemoto. Ngokusasazwa kwefayili efanayo, iimveliso zibonisa amandla omatshini aphezulu kunye nokumelana nobushushu obuphezulu, okwenza ukuba zisetyenziswe ngokubanzi kumacandelo amashishini aphakathi ukuya phezulu kunye nohlobo lwemveliso eqhelekileyo.

Iikhompawundi zokubumba isitofu:Ifanelekile kwiinkqubo zokubumba inaliti, ezi zixhobo zinokuhamba kakuhle kwaye zinokuzaliswa ngokukhawuleza kwaye zinyangelwe kumatshini wokubumba inaliti, okukhokelela ekusebenzeni okuphezulu kwemveliso kunye nokuzenzekelayo. Zikulungele ukuveliswa kobuninzi bezinto ezincinci ukuya kubukhulu obuphakathi, obuqhelekileyo obucwangcisiweyo, obufana neepaneli zokutshintsha izixhobo zendlu, izihlanganisi ze-automotive electronic, kunye neendawo ezincinci zokugquma umbane. Ngokuthandwa kweenkqubo zokubumba iinaliti kunye nokulungiswa kokuhamba kwezinto, isabelo sentengiso yezi mveliso sikhula ngokuthe ngcembe, ngakumbi njengoko zihlangabezana neemfuno ezinkulu zemveliso yeemveliso zabathengi.

IiNdawo zokuSebenza zePhenolic Molding Compounds

IsiXhobo soMbane/sombane:Lo ngumongo wemeko yesicelo, ukugquma amacandelo okugquma kunye namalungu olwakhiwo lwezixhobo ezinjengeenjini, iziguquli, iziqhekezi zesekethe, kunye neereyilayi, ezinjengee-motor commutators, iifreyimu zokugquma i-transformer, kunye neetheminali zokwaphula isekethe. I-insulation ephezulu kunye nokushisa okuphezulu kweqondo lokushisa kwee-phenolic molding compounds kuqinisekisa ukusebenza ngokukhuselekileyo kwezixhobo zombane phantsi kombane ophezulu kunye neemeko ezitshisa kakhulu, ukuthintela imijikelezo emfutshane ebangelwa ukungaphumeleli kwe-insulation. Iikhompawundi zokubumba ezicinezelayo zisetyenziswa ikakhulu kumacandelo abalulekileyo okufakwa kwenaliti, ngelixa iikhompawundi zokubumba inaliti zilungele ukuveliswa kobunzima bezinto ezincinci ze-elektroniki.

Umzi mveliso weemoto:Isetyenziselwa izinto ezikwazi ukumelana nobushushu kwiinjini zeemoto, iinkqubo zombane, kunye ne-chassis, ezinje nge-injini ye-cylinder head gaskets, i-ignition coil housings, izibiyeli ze-sensor, kunye nezixhobo ze-braking system. La malungu kufuneka amelane namaqondo obushushu enjini exesha elide (120-180℃) kunye neempembelelo zokungcangcazela. Iikhompawundi zokubumba i-Phenolic zihlangabezana nezi mfuno ngenxa yokumelana nobushushu obuphezulu, ukuxhathisa kweoli, kunye namandla omatshini. Zikwakhaphukhaphu kunezixhobo zentsimbi, ezinegalelo ekunciphiseni ubunzima kunye nokusebenza kakuhle kwamafutha ezimotweni. Iikhompawundi zokubumba zokunyanzeliswa zilungele amacandelo angundoqo amelana nobushushu ajikeleze i-injini, ngelixa iikhompawundi zokubumba iinaliti zisetyenziselwa izinto zombane ezincinci kunye neziphakathi.

Izixhobo Zasekhaya:Ilungele ulwakhiwo olukwaziyo ukumelana nobushushu kunye nezinto ezisebenzayo kwizixhobo ezinje ngabapheki berayisi, ii-oveni, ii-oveni zemicrowave, kunye noomatshini bokuhlamba, abanje ngenkxaso yembiza yokupheka irayisi yangaphakathi, izixhobo zokufudumeza i-oveni, izixhobo zokugquma umnyango we-oveni ye-microwave, kunye nomatshini wokuhlamba wokugquma iimoto. Amacandelo esixhobo kufuneka amelane namaqondo obushushu aphakathi ukuya phezulu (80-150℃) kunye nemekobume efumileyo ngexesha lokusetyenziswa kwemihla ngemihla.Iikhompawundi zokubumba iPhenoliczibonelela ngezibonelelo ezibalulekileyo ekuxhathiseni ubushushu obuphezulu, ukumelana nokufuma, kunye nexabiso eliphantsi. Izitofu zokubumba iikhompawundi, ngenxa yokusebenza kwazo okuphezulu kwemveliso, ziye zaba lukhetho oluphambili kushishino lwezixhobo zekhaya.

Ezinye izinto ezisetyenziswayo ziquka i-aerospace (efana nezixhobo ezincinci zokugquma kwizixhobo ezihamba emoyeni), izixhobo zonyango (ezifana namacandelo obushushu obuphezulu), kunye neevalvu zamashishini (ezifana nezihlalo zokuvala ivalve). Ngokomzekelo, iitreyi zokushisa eziphezulu zokushisa kwizixhobo zonyango kufuneka zixhathise i-121 ° C yoxinzelelo oluphezulu lwe-sterilization, kunye ne-phenolic molding compounds zinokuhlangabezana neemfuno zokumelana nobushushu kunye nococeko; Izihlalo zokutywina zevalve yeshishini kufuneka zixhathise ukubola kwemidiya kunye namaqondo obushushu athile, ziqaqambisa ukuguquguquka kwazo kwiimeko ezininzi.
