Laminates: Ngā Āhuatanga me tono

Nga pūnaha mātao, pūrere matatini me ngā hanganga, e kua nui haere ngā whakaritenga whakahaere, te whakamahi i ngā rauemi hiato motuhake. Ka rite ki te tikanga, ehara i te mea ao a auraa hua tino motuhake ki te mahi i roto i ngā āhuatanga wera me te haumākū tino. Ēnei isolators ngā te laminates e whai ake nei: getinaks, PCB, muka karaihe, me te ratou akatuke'anga. Na roto i te huinga o te kaha, me te ngāwhā mātao huru maitatai e taea te whakamahi taua composites i roto i ngā hanganga kawenga mo tona whakaaro tikanga, ngā pūrere me whakatangi.

Ko te whakamahi o te kirihou Whakakirihōu

Ko te tino kanorau te tūāwhiorangi o whakamahinga o enei waerau. Tenei ahumahi mīhini taputapu, me te hangarau rererangi, me ahumahi whakanao, me te te hanga, me te matū ahumahi. Nga wahi katoa e hiahiatia ana te whakamahi o te mātao hiko, te whakamahi o taua rauemi. E kore te mea tenei ki te korero o to ratou rehe. tuhia te reira i te whānui o akatuke'anga, e tapaea laminates ngā. arotahi te whakamahi o te hanganga o ia putanga i runga i ngā wāhanga motuhake. Hei tauira, getinaks tika mō te hanga wae iti-utu i roto i ngā pūrere hiko, me ngā rauemi rakau-ēnei i roto i te hanganga mārō e whakamahia ana i roto i te tikanga hangarau. Tino whānui whānuitanga o te PCB, e hipokina me ahumahi hiko, me complexes matūngahinu, me te he mea pai.

He aha hua laminates?

Ko te kiri he he rauemi hiato e hāngai ana i runga i - te ruruku polymeric. I roto i te tikanga ki te whakapakari i te turanga mahi kua whakamahia hoki i roto i ngā papa kei whakapakari filler. I roto i te mau parau te tahi atu, te laminates - te huinga o rua wāhanga tuatahi kanohi kōpaki me te filler. Ka rite ki te whakauru tuatahi whakamahia kapia waihanga. Ka taea te hanga te reira o te pareaku, epoxy, phenol-formaldehyde me ētahi atu matū. Ko reira ano hoki noa te whakamahi o waerau, i roto i nei - silicone me ngā rauemi fluoropolymer. Ko te whakakī, ka taea te mahi te mahi i te rauemi raw tuku iho rite papa kiripaka me te pepa cellulose muka.

Taipitopito o Laminates

I roto i te putanga matarohia te kiri ko te rauemi whārangi whakanohoia e te i runga i te momo o awhi anga tikanga. momo kakahu Iti noa. Ka taea e whārangi matotoru ngā i 0.4 ki te 50 mm, i runga i te momo, me te hanganga insulator rānei. Ano, he momo o te rahi i roto i te roa me te whanui. rōpū kaka Paerewa, mo te tauira, kua 1200x1000 mm he tawhā toharite. nohoia laminates 'ulungaanga mahi, ua faaite te kaha ki te tu ngā tikanga pāmahana. Ano, te kauhanga roa toharite mō te kirihou angamaheni taua awhe i -60 ° C ki te 120 ° C. Kaupapa ki te whakauru o ngā pūwhakakē atu, e taea te whakawhānui i tēnei awhe.

āhuatanga kaka kōata

whakaritea te mahi o tenei kirihou e tona tokotoko, e ngā maha ngā paparanga o te karaihe ēnei tahi i te hangarau te pēhi wera. Ko te ruruku i roto i tenei take ko te epoxy-wae rewatau. Ki te āhuatanga taketake i e farii ki tenei momo laminates ngā ātete wera tiketike, tiaki i ngā pānga kino o te houku me aunoa kaha. Ano, pērā composites maha, muka karaihe ko he rauemi taiao e faarahi tona mara tono. Na whai wāhi ona painga i roto i te mākete ki teitei te kounga uruhanga me te mauroa.

ngā āhuatanga Micarta

Ko tetahi rerenga noa o te kiri, whakamahia nei te rite te tuuraa i rauemi. Ko te āhuatanga mahi o te hiato tautuhi te tïpako pepa tukinotia ki te ranunga o te phenolic ranei epoxy resins.

e kore e taea e tenei kirihou whakamanamana i te huinga o taua 'ulungaanga rite kaha mīhini me te kaha ki te akakoromaki ki pāmahana tino. Otiia ngohengohe i roto i ngā o te tukatuka taea ki te hanga i te pūtake o te papa mania tā o te rahi katoa. I tua atu, ko reira te laminates na'ina'i, me i arahina ki to ratou whakamahi whānui i roto i te mauhaa. Mai i te rauemi taua, i roto i ngā mo te whakaputa takatakahia wāhanga logistics tono kiritaki ngaohiko iti.

ngā āhuatanga PCB

Material i hanga o papanga miro i wera te pēhi ki te rōpū phenolformaldehyde tua rewatau kōpaki. E tono whakaratohia he papanga PCB turanga kaha shock tiketike, me te taikaha. Pūtake ngāwari tukatuka e kōhao, tapahi, me te takahi. Tenei meinga tona kounga rauemi whakamahia i roto i te āhuatanga hanga tukanga e te hunga i raro i te mana o pikaunga hiko, me te hangarau e.

I roto i tenei take, i reira e rave rahi ngā kāwai, e kua wehea laminates koloa. E whakahuatia Āhuatanga o te kāwai tuatahi i roto i te puka o te taratahi hiko nui haere, e taea ai te whakamahi o te rauemi me te i roto i te rangi, a i roto i te hinu hiko. āhuatanga te kāwai tuarua e pai ake ngā āhuatanga hangarau, na kua meinga o tenei rōpū nga wahi kirihou e pea atu ki te tahuri ki te mahi. He hoki whakarerekētanga PCB motuhake, hangaia hoki te whakamahi i pāmahana teitei.

Ko te āhuatanga o laminates rakau-kirihou

Ko te rerekētanga hanganga matua o te tuuraa rauemi e whakamahia ana o tenei momo te rite te rakau filler turanga. I roto i ngā, pepa hiato o veneer kīnaki kia 0.3-0.6 mm o. Ki te waerau o tūturu rauemi fetu'utaki roto resins resole. Ka rite ki te hua, e tau ana te rauemi hiato ake āhuatanga anti-waku, ātete ki pāpāho pukuriri, me te ara abrasion, e kore e taea e nei te tu i te tahi atu laminates.

Āhuatanga, tono me ngā whakaritenga mahi i roto i tenei take e tika ana ki te huinga o te huinga o ngā āhuatanga. Ua faaite mau huru mahi o te rauemi e kore haumarutanga anake tinana, engari ano hoki makuku ātete, āhuatanga uruhanga me te pūmautanga tiaki i ultra-iti pāmahana i -250 ° C. Ki te whakaaro ki te whakamahi, e pai integrated rakau-laminates ki te tikanga o ngā waeine waku, ahunga, vaolo waipēhi me te tahi atu pūnaha hangarau.

mutunga

composites Modern i tuatahi whakawhanakehia ki te whakaputa i ngā rauemi tiketike-kaha e taea te whakakapi etahi alloys whakarewa. Ko te mutunga, taea ki te kitea he rerekē ki te whakamaunga tuku iho i roto i te puka o rakau kaka te rāngai hanga ko. I roto i te tahuri, kua riro nga laminates hei whakakapinga pai ki insulators tuku iho. e kore e ratou whakamahia te wahi tango ki te tāpae huruhuru kohuke awhi puru ranei, engari motuhake motuhake, i te mea e kore e nui ngā āhuatanga tikanga o tenei momo, kei te kaha te tūhura waerau paparanga hou. Heoi, e kore e araia te reira me te takanga heke mai o taua insulators i motu whakamahi wāhanga. I roto i tetahi take, te fakakaume'a taiao o kaka kōata e taea whai wāhi.
