Laminates: katundu ndi Mapulogalamu

Machitidwe kutchinjiriza zipangizo zovuta ndi nyumba, amene kuchuluka amafuna ntchito, ntchito zipangizo wapadera gulu. Monga ulamuliro, si chilengedwe ndi mankhwala apadera kwambiri anatanthauza kuti ntchito kwambiri kutentha zinthu. isolators zikuphatikizapo laminates zotsatirazi: getinaks, PCB, CHIKWANGWANI galasi, komanso zosintha awo. Kudzera osakaniza mphamvu ndi kutchinjiriza matenthedwe makhalidwe nsanganizo akhoza kugwiritsidwa ntchito mu nyumba udindo cholinga chake, zipangizo ndi zida.

Ntchito laminated mapulasitiki

The sipekitiramu ntchito ya ma polima awa ndi yosiyanasiyana. Izi makina chida mafakitale ndi luso ndege, ndi mafakitale kupanga, komanso kumanga ndi mankhwala mafakitale. Kulikonse chofunika ntchito kutchinjiriza magetsi, ntchito zipangizo zimenezi. Izi si kulankhula za ntchito zake zosiyanasiyana awo. Iwo anati osiyanasiyana zosintha, amene azipereka laminates. Ntchito zikuchokera lililonse Baibulo lolunjika pa malo enieni. Mwachitsanzo, getinaks oyenera kupanga zigawo otsika mtengo popanga zipangizo zamagetsi, ndi nkhuni laminated zipangizo kudzera dongosolo okhwima ntchito zimagwirira ntchito luso. ukulu ndithu kwambiri PCB, amene chimakwirira ndi makampani magetsi, ndi petrochemical maofesi, komanso chida chabwino.

kubala laminates chiyani?

The laminate ndi chuma gulu zochokera - ndi binder polymeric. Pofuna kulimbikitsa ntchito m'munsi amagwiritsidwanso ntchito zigawo ili ikuthandizira filler. Mu mawu ena, laminates - kuphatikiza kwa zigawo ziwiri chachikulu ankaimira binder ndi filler. Monga pophika choyamba ntchito utomoni kupanga. Iwo akhoza kukhala ndi poliyesitala, epoxy, phenol-formaldehyde ndi zinthu zina. Ndi wamba kugwiritsa ntchito ma polima, Pakati - silikoni ndi zipangizo fluoropolymer. Koma kudzazidwa, ndiye ntchito angachichite zipangizo chikhalidwe yaiwisi monga asibesitosi ndi pepala mapadi ulusi.

Tsatanetsatane wa Laminates

Mu Baibulo tingachipeze powerenga za laminate ndi pepala zinthu zomwe aikidwa pa mtundu wa ochiritsira mapanelo kuyembekezera. nsalu zochepa wamba mitundu. Mapepala makulidwe akhoza osiyanasiyana monga mamilimita 0.4 50, malinga zosiyanasiyana ndi insulator zikuchokera. Komanso, zosiyanasiyana zamitundu m'litali ndi m'lifupi. Standard fiberglass gulu, mwachitsanzo, ali ndi magawo pafupifupi 1200x1000 mm. makhalidwe ntchito wogwidwa laminates, anasonyeza mphamvu kupirira mavuto osiyanasiyana kutentha. Kachiwiri, ambiri kulowera chifukwa lililonse pulasitiki ranges otero ochokera kwa -60 ° C kwa 120 ° C. Phunziro kwa kulolerana wa modifiers zina, osiyanasiyana izi zikhoza kukodzedwa.

katundu fiberglass

Ntchito a pulasitiki izi anatsimikiza ndi kapangidwe kake, womwenso zigawo zingapo galasi laminated pamodzi ndi luso otentha kukanikiza. The binder mu nkhani iyi ndi thermosetting epoxy-chigawo. Kwa katundu zofunika zimene anapatsidwa laminates mtundu uwu monga mkulu kutentha kukana, chitetezo ku mavuto chinyezi ndi mphamvu mawotchi. Komanso, mosiyana ndi nsanganizo ambiri, galasi CHIKWANGWANI ndi chuma wochezeka kuti lakamba zambiri ntchito kumunda wake. Ndi chikoka ake mu msika amathandiza kuti apamwamba dielectric khalidwe ndi durability.

katundu Micarta

kusintha chinanso cha laminate, amene ntchito ngati chimateteza zakuthupi. The katundu ntchito ya gulu la amati pepala gawo lapansi mankhwala osakaniza phenolic kapena epoxy resins.

pulasitiki uwu sungakhoze kudzitama osakaniza makhalidwe monga mphamvu mawotchi ndi luso kupirira kutentha. Komabe malleable mawu a processing amalola kupanga maziko a kusindikizidwa matabwa dera zamitundu yonse. Komanso, ndi laminates yotsika mtengo, ndi zomwe zinachititsa kuti ntchito zawo ambiri chida. Kuyambira amenewa ndi, makamaka yopangira stamped zigawo mmene kukumana otsika voteji ogula ofunsira.

katundu PCB

Zofunika anapanga nsalu thonje ndi otentha kukanikiza ndi thermosetting binder phenolformaldehyde Kuwonjezera gulu. ntchito kuti anapereka nsalu m'munsi PCB mkulu compressive mphamvu, ndi kulimba. Maziko mosavuta kukonzedwa ndi kuboola, kudula ndi mitundu. Unachititsa zinthu zidazo ntchito zinthu ndondomeko kupanga amene mchikakamizo cha katundu magetsi ndi makina.

Pankhaniyi, pali magulu angapo, omwe zidzasankhidwa laminates chofunika. Katundu wa gulu yoyamba anafotokoza mu mawonekedwe a kuchuluka kudzipatula magetsi, amene amalola ntchito chuma ndi mu mlengalenga, ndi mafuta thiransifoma. Gulu lachiwiri amakhala ndi katundu bwino makina, chotero mbali pulasitiki anapangidwa kwa gulu ili ena amakhala ndi kutembenukira kwa thupi. Palinso zosintha wapadera PCB, kuti tizigwiritsa ntchito pa kutentha okwera.

The katundu wa laminates nkhuni pulasitiki

Waukulu structural kusiyana zipangizo chimateteza wa mtundu uwu ntchito ngati nkhuni filler m'munsi. Makamaka, gulu mapepala maonekedwe lowonjezera dongosolo la 0.3-0.6 mm. Ndi ma polima chifukwa cha masoka zinthu amalankhula kupyolera resins resole. Motero, nkhani gulu zimakhala bwino katundu odana ndi mikangano, kukana kuti media mwamakani ndipo ngakhale kumva kuwawa, omwe sangathe kupirira laminates ena.

Katundu, ntchito ndi zofunika ntchito mu nkhani iyi ndi chifukwa osakaniza ya makhalidwe. Amasonyezera makhalidwe ntchito za chuma osati thupi chitetezo, komanso kukana chinyezi, katundu dielectric ndi mtendere kuteteza pa kutentha kopitilira muyeso-otsika pa -250 ° C. Pankhani ntchito, matabwa laminates bwino Integrated mu njira mayunitsi mikangano, mayendedwe, mavavu hayidiroliki ndi machitidwe ena luso.

Pomaliza

nsanganizo amakono poyamba anayamba kubala mkulu-mphamvu zipangizo kuti m'malo mwa ena zitsulo kasakaniza wazitsulo. Chifukwa, nchito yomanga ndi kupeza njira ina ku fixture makolo mu mawonekedwe a ndodo fiberglass. Nawonso laminates akhala m'malo abwino insulators chikhalidwe. Iwo ntchito pamene atengedwa ku amaunjika mchere nkhosa kapena mapanelo Nkhata Bay, koma apadera kagawo kakang'ono, amene si zokwanira makhalidwe ochiritsira wa mtundu uwu, zikukangalika kuwona ma polima latsopano magawo. Komabe, si lilibe ndi pakutchulidwa tsogolo la insulators ngati ntchito zapakhomo gawo. Mulimonsemo, ochezeka chilengedwe fiberglass kuti angathandize.
