Izinto zokusebenza eziphezulu zePPO ezivela kwi-SIKO.

PPO impahla evela SIKO

I-Polyphenylene oxide okanye i-polyethylene ether Eyaziwa ngokuba yi-polyphenylene oxide okanye i-polyphenylene ether, yintlaka ye-thermoplastic ekwaziyo ukumelana nobushushu obuphezulu.

Iimpawu kunye nezicelo

I-PPO yiplastiki yobunjineli be-thermoplastic esebenza ngokugqwesileyo, ukufakwa kombane okugqwesileyo kunye nokumelana namanzi, kunye nokuzinza okuhle komgangatho.

I-1, iipropathi ze-dielectric zeeplastiki zobunjineli kuqala

I-PPO ye-resin ye-molecular structure ngaphandle kwamaqela anamandla e-polar, iipropati zombane ezizinzileyo, zinokugcina iimpawu zombane ezilungileyo kuluhlu olubanzi lobushushu kunye nokuphindaphinda.

① I-Dielectric constant: 2.6-2.8 yeyona nto incinci kwiiplastiki zobunjineli ② I-Tangent yelahleko ye-dielectric I-Angle: 0.008-0.0042 (phantse ayichatshazelwa bubushushu, umswakama kunye nobuninzi) ③ Ukumelana nomthamo: 1016 yeyona nto iphezulu kwiiplastiki zobunjineli

I-2, iipropati ezilungileyo zoomatshini kunye ne-thermal ye-PPO ye-molecular chain, iqulethe inani elikhulu lesakhiwo se-ring ring, i-molecular chain sensitivity yomelele, amandla e-resin mechanical aphezulu, ukuxhathisa okugqwesileyo, utshintsho lobushushu luncinci kakhulu. I-PPO inokumelana nobushushu obuphezulu, iqondo lokutshintsha kweglasi ukuya kuthi ga kwi-211 ℃, indawo yokunyibilika i-268℃.

I-3, ukuxhathisa okugqwesileyo kwamanzi i-PPO i-non-crystalline resin, kuluhlu lobushushu obuqhelekileyo, intshukumo encinci ye-molecular, akukho maqela amakhulu e-polar kwikhonkco eliphambili, umzuzu we-dipole awenzeki ipali, ukumelana kwamanzi kuhle kakhulu, lelona zinga liphantsi lokufunxa amanzi. iintlobo zeplastiki zobunjineli. Iimpawu zayo zenyama zisenokonakala okuncinci emva kokuntywila emanzini ashushu ixesha elide.

I-4, Isalathisi se-oksijini ye-PPO yokucima i-self-extinguishing yi-29, into eyazicimayo, kunye ne-oxygen index ye-polyethylene enefuthe eliphezulu yi-17, into evuthayo. Ukudityaniswa kwezi zibini kukutsha okuphakathi. Xa usenza i-PPO ye-flame retardant, akukho mfuneko yokongeza i-halogen flame retardant, ukongeza i-phosphorous-containing flame retardant dose inokufikelela umgangatho we-UL94. Ukunciphisa ukungcoliseka kwendalo.

I-5, izinga lokucutheka eliphantsi, uzinzo olulungileyo lwe-dimensional; I-Non-toxic, i-low density 6, ukuchasana kwe-dielectric kunye nokuchasana nokukhanya kwe-PPO acid, i-alkali kunye ne-detergent kunye nezinye i-corrosion esisiseko, phantsi kwemeko yoxinzelelo, i-oyile yamaminerali kunye ne-ketone, i-solvents ye-ester iya kuvelisa ukuphazamiseka koxinzelelo; Izinyibilikisi zendalo ezifana ne-aliphatic hydrocarbons, i-halogenated aliphatic hydrocarbons kunye ne-aromatics hydrocarbons zinokunyibilika kwaye zinyibilike.

Ubuthathaka be-PPO kukuxhathisa ukukhanya, ixesha elide phantsi kokukhanya kwelanga okanye ukusetyenziswa kwesibane se-fluorescent kuvelisa i-discoloration, umbala ophuzi, isizathu kukuba ukukhanya kwe-ultraviolet kunokwenza ikhonkco le-ether elivumba liqhekeke. Indlela yokuphucula ukumelana nokukhanya kwePPO iba sisihloko.

Ukusebenza kwePPO kumisela indawo kunye nobungakanani besicelo:

① Ubuninzi beMPPO buncinci, kulula ukusetyenzwa, ubushushu bokutshintsha kwe-thermal kwi-90-175 ℃, kukho izinto ezahlukeneyo zokuchazwa kwempahla, uzinzo oluhle lomgangatho, zilungele ukwenziwa kwezixhobo zeofisi, izixhobo zasekhaya, iibhokisi zekhompyuter, i-chassis kunye namalungu achanekileyo.

② I-MPPO i-dielectric engaguqukiyo kunye nelahleko ye-dielectric I-angle tangent kwiiplastiki ezintlanu zobunjineli jikelele kweyona ndawo iphantsi, oko kukuthi, ukufakwa kwe-insulation, kunye nokumelana nobushushu okulungileyo, kufanelekile kushishino lombane. Ifanelekile ukwenza iindawo zokukhusela umbane, ezifana nesakhelo se-coil, umnikazi ityhubhu, i-shaft yokulawula, i-sleeve ye-transformer shield, ibhokisi ye-relay, insika ye-insulating kunye nokunye, ezisetyenziswa kwiimeko ezimanzi kunye nezilayishiwe.

③ I-MPPO inokumelana nokuxhathisa kwamanzi kunye nokuxhathisa ubushushu, efanelekileyo ukwenza iimitha zamanzi, iimpompo zamanzi kunye neetyhubhu zelaphu ezisetyenziswa kwiifektri ezilukiweyo ezifuna iimpahla zabathengi ezomeleleyo xa zipheka. Iityhubhu zomsonto ezenziwe ngeMPPO zinobomi obude benkonzo.

④ I-dielectric engaguqukiyo kunye nelahleko ye-dielectric I-angle tangent yeMPPO ayichatshazelwa bubushushu kunye nenombolo yomjikelo kwiiplastiki zobunjineli, kwaye inokumelana nobushushu obulungileyo kunye nokuzinza kwe-dimensional, ezilungele ishishini lombane.
