Dab tsi yog cov yas yog cov hluav taws xob transformer pob txha ua los ntawm?

Dab tsi yas yog lub pob txha ntawm lub tshuab hluav taws xob ua los ntawm?

① Nylon (NYLON): dawb thiab pob tshab, nrog rau qee qhov kev nqus dej, muaj zog roj tsis kam, toughness, zoo ductility, tsis tawg, tab sis yooj yim rau yaj thaum rhuab, yooj yim deform, kub tsis kam yog feem ntau txog 110 degrees, hluav taws kub. Kev ntsuam xyuas yog 94V-2 lossis 94V-HB, qhov hluav taws xob tiv thaiv yog 27KV / mm, thiab nws qhov chaw yog du; Vim yog cov yam ntxwv saum toj no, cov ntaub ntawv nylon feem ntau yog siv los ua cov tshuab hluav taws xob tsawg tsawg nrog cov kev xav tau qis qis lossis cov coil inductors.

② PBT: feem ntau yog xim dawb, xim av los yog beige, kuj zoo toughness, kub tsis kam ntawm li 120 degrees, yooj yim rau deform tom qab cua sov (thermal deformation kub ntawm 205 degrees), hluav taws kub ntsuas ntawm 94V-0, zoo heev rwb thaiv tsev kev ua tau zoo, voltage tsis kam ntawm 22KV / mm, thiab tsis du nto; Vim yog cov yam ntxwv saum toj no, cov khoom siv no feem ntau yog siv los ua cov hloov pauv me me thiab nruab nrab lossis inductors nrog cov xaim me me. Nyob rau tib lub sijhawm, cov khoom siv no yog pheej yig, yooj yim rau kev yuav, thiab tsis tshua muaj nqi tsim khoom, uas tsim nyog rau kev tsim khoom loj.

③ PET: feem ntau yog xim dub, yooj yim yaj thaum rhuab, dav toughness (me ntsis zoo dua li nylon), yooj yim rau daim ntawv, kub tsis kam ntawm li 130 degrees, nyuaj deform thaum rhuab (thermal deformation kub ntawm 246 degrees), hluav taws kub ntsuas ntawm 94V -0, rwb thaiv tsev kev ua tau zoo ntawm cov khoom no yog me ntsis phem dua PBT, voltage kuj ntawm 18kV / mm, nws nto tsis du, thiab nws yuav siv tau raws li high-frequency transformer moj khaum, inductance plhaub, thiab lwm yam. nqi me ntsis siab dua PBT.

④ LCP: feem ntau beige, yog ib hom kua siv lead ua polymer, uas yog nruab nrab ntawm PET thiab bakelite. Nws muaj zoo hardness thiab toughness. Cov khoom siv ib txwm, xws li E-4008, muaj qhov kub thiab txias deformation ntawm 313 degrees. Nws tseem muaj qhov zoo ntawm qhov ruaj khov, nkag siab tsis kam, tsis tshua muaj thermal expansion coefficient thiab tsis tshua muaj siab dielectric zog ntawm qhov kub thiab txias. Nws feem ntau yog siv los ua SMD transformers nyob rau hauv lub tshav pob ntawm transformers, nrog ib tug nplaim-retardant ntsuam xyuas ntawm 94V-0, Tab sis nws yog kim.

⑤ PHENOLIC: feem ntau yog xim dub, nws yog cov khoom siv zoo tshaj plaws rau kev hloov pauv, xws li Changchun T373J, T375J, Sumitomo PM9820, PM9630, thiab lwm yam. Nws yog nkig thiab tawg, nrog rau qhov ntsuas hluav taws kub ntawm 94V{{6 } }, tshwj xeeb tshaj yog tiv taus kub (370 degree C), qhov hluav taws xob tsis kam ntawm 10KV / mm, thiab du nto; Nws tuaj yeem hais tias bakelite yog ib qho ntawm cov khoom siv dav tshaj plaws hauv kev hloov pauv. Vim tias nws muaj qhov kub thiab txias tsis kam, tsis muaj deformation, thiab nruab nrab qhov hluav taws xob tsis kam, nws yog qhov tsim nyog rau cov khoom siv hluav taws xob loj thiab nruab nrab, tab sis nws yog qhov tsis yooj yim, uas yog qhov tsis tuaj yeem, thiab cov ntaub ntawv zoo li no tsis tuaj yeem siv thiab rov siv dua.

Lub high-frequency transformer feem ntau yog ua los ntawm bakelite, uas muaj qhov kub thiab txias tsis kam, tsis yooj yim rau deform thiab muaj luster. Piv nrog cov yas high-frequency transformer, tsuas yog qhov tsis zoo yog tias nws yooj yim tawg.

Txawm li cas los xij, high-frequency transformers ua los ntawm PET thiab PBT tsis tshua hnov ​​​​los yog pom ntawm cov phooj ywg. Ob yam khoom yog dab tsi? Dab tsi yog qhov txawv ntawm nws thiab cov pob txha Bakelite?

PET yog ua los ntawm polyethylene terephthalate. PET yog cov mis nyuj dawb los yog lub teeb daj uas muaj crystalline polymer nrog du thiab ci ntsa iab. Nws muaj zoo heev lub cev thiab txhua yam khoom nyob rau hauv ib tug dav kub ntau yam. Nws siv sijhawm ntev kub tuaj yeem ncav cuag 120 degree, thiab nws cov hluav taws xob rwb thaiv tsev zoo heev. Txawm tias nyob rau hauv qhov kub thiab txias, nws cov hluav taws xob kev ua tau zoo tseem zoo, tab sis nws cov corona kuj tsis zoo, creep tsis kam, qaug zog tiv thaiv, kev sib txhuam tsis kam, thiab seem stability yog zoo.

PBT yog ib qho ntawm tsib qhov loj engineering yas, polybutylene terephthalate (PBT), nws lub npe Askiv yog polybutylene terephthalate (PBT luv luv). Nws yog thermoplastic polyester. Piv nrog rau lwm cov thermoplastic engineering yas, cov PBT tsis muaj zog muaj zog ua haujlwm zoo dua thiab cov khoom siv hluav taws xob. Nws tuaj yeem siv los ua qhov rov qab hloov pauv ntawm TV, tsheb distributor thiab ignition coil, cov khoom siv hauv chaw ua haujlwm plhaub thiab lub hauv paus, ntau yam tsheb sab nrauv, cua txias kiv cua, hluav taws xob qhov cub hauv paus, cov khoom siv hauv chaw ua haujlwm
