Chii Chinonzi Halogen-Yemahara PCB Uye Nei Dzakakosha?

MaPCB ndiwo musimboti wezvishandiso zvemagetsi zvemazuva ano, achishanda senzira huru yekubatanidza nekusimbisa zvikamu zvakasiyana-siyana. Kazhinji, mabhodhi aya aivimba nezvinodzivirira moto zvine brominated nechlorine kuti zvisvike padanho rekuchengetedza moto. Zvisinei, kunetseka pamusoro pemigumisiro yehalogens, dzakadai sebromine nechlorine—kunyanya utsi hune chepfu hwazvinoburitsa kana zvapiswa—kwakaita kuti pave nekudiwa kukuru kwezvinhu zvePCB zvisina halogen zvine hushamwari nezvakatipoteredza.

MaPCB asina halogen anopa imwe nzira inoshanda, achitsiva ma halogen ane njodzi ne organic phosphorus-based flame retardants. Shanduko iyi inobvumira vagadziri kugadzira ma PCB akachengeteka, ane hushamwari kune nharaunda pasina kukanganisa kuchengetedzeka kwemoto kana mashandiro. Sezvo indasitiri iri kuramba ichishandisa ma laminates nema prepreg asina halogen, zvakakosha kuti vagadziri nevagadziri vePCB vanzwisise mabhenefiti, sarudzo dzezvinhu, uye pfungwa dzekugadzira dzinobatanidzwa mukuchinja uku. Ungave uri mugadziri wemagetsi akazvipira kuchengetedza nharaunda kana mugadziri wePCB ane chinangwa chekugara ari pamberi pemazinga ezvakatipoteredza, gwara iri rinopa ongororo yakazara ye ma PCB asina halogen nebasa rawo mune ramangwana remagetsi anochengetedza nharaunda.

Chii Chinonzi Halogens, uye Nei Uchidziviswa?

Ma halogen anosanganisira boka rezvinhu zvemakemikari zvinosanganisira fluorine, chlorine, bromine, iodine, uye astatine. Panyaya yekugadzira ma PCB , ma halogen anonyanya kutaurwa nezvawo i chlorine ne bromine. Zvinhu zviviri izvi zvakashandiswa zvakanyanya muPCB laminates sezvinodzivirira moto.

Iyo brominated uye chlorinated flame retardant masisitimu anoshandiswa mune zvechinyakare PCB zvinhu zvinotora akasiyana siyana, senge polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs), uye polyvinyl chloride (PVC). Kana ikapiswa, mishonga ine halogenated iyi inoburitsa zvinhu zvine njodzi, zvinosanganisira dioxins, furan, nemagasi ane acidic.

Kuratidzwa kuhutsi hune muchetura hunogadzirwa nehalogenated flame retardants kunopa njodzi huru:

1. Njodzi Dzemamiriro Ekunze: Kuburitswa kwehupfu uhu kunogona kukonzera kusvibiswa kwezvakatipoteredza uye bioaccumulation mumaketani echikafu, zvichikanganisa ecosystems.
2. Hutano Kunetsekana: Kuratidzwa kune halogenated flame retardants kwakabatana nenyaya dzakasiyana dzehutano, kusanganisira kukanganisa kweendocrine, kukuvadzwa kwekubereka, gomarara, uye kusagadzikana kwekuvandudza kwetsinga.
3. Equipment Corrosion: Iko kuparara kweasidhi magasi anogadzirwa panguva yekupisa kunogona kukonzera kuparara kwemidziyo yemagetsi.

Sezvo kuziva kwekunetseka uku kuri kuramba kuchikura, vagadziri vemagetsi vari kuchinjika kuenda kune-halogen-yemahara zvinhu kudzikamisa nharaunda, hutano, uye kuvimbika njodzi dzine chekuita nehalogenated makomponi. Ngationgororei mabhenefiti ekubvisa halogens mune zvakadzama.

Mabhenefiti Akakosha eHalogen Yemahara PCB Zvishandiso

Halogen-isina PCB laminates uye prepregs inopa akati wandei akakosha mabhenefiti pamusoro pechinyakare halogenated vamwe. Imwe yemabhenefiti ekutanga kuchengetedzwa kwemoto uye kuderedzwa kwehuturu. Kusiyana nezvinhu zvine halogenated, maPCB asina halogen haabudise utsi hunoparadza, utsi, kana magasi ane muchetura kana apiswa. Uku kudzikiswa kwenjodzi dzehupfu hwemoto kunowedzera kuchengetedzwa kwese, zvichiita kuti halogen-isina maPCB ive sarudzo yakachengeteka mumashandisirwo akasiyana siyana.

Chimwe chinhu chakakosha ndechekutevedzera mitemo yezvakatipoteredza. Sezvo ruzivo rwezvakatipoteredza ruchiwedzera, masangano ekutonga pasi rese ari kusimbisa kudzora kwakasimba pakushandiswa kwema halogen muzvigadzirwa zvemagetsi. Ma PCB asina halogen anovimbisa kutevedzera zvirongwa zvakaita semirairo yeWaste Electrical and Electronic Equipment (WEEE) uye mirairo yeRestriction of Hazardous Substances ( RoHS ), ese ari maviri anodzikamisa kushandiswa kwezvinhu zvine njodzi mumidziyo yemagetsi. Pamusoro pezvo, ma PCB asina halogen anopa kuvimbika kwakawedzerwa uye kuenderana nekushanda nekubvisa magasi anoparadza anogona kukuvadza zvikamu zvemagetsi, zvichikonzera hupenyu hwese hwese hwese uye kuvandudzwa kwekushanda.

Dhizaini Mafungiro eHalogen-Mahara PCBs

Nepo halogen-isina PCB zvinhu zvinopa zvinozivikanwa kwezvakatipoteredza uye hutano mabhenefiti, zvinogona kupesvedzera mamwe magadzirirwo uye ekugadzira zvinhu zvinofanirwa kunyatso tariswa. Chimwe chakadaro ndechekuita kwemagetsi. Mamwe halogen-asina laminates anogona kuratidza yakakwira zvishoma dielectric kugara, izvo zvinogona kukanganisa impedance kushivirira uye chiratidzo chekuvimbika. Vagadziri vePCB vanofanirwa kutarisisa kurongeka uye dhizaini kugadzirisa misiyano iyi uye kuve nechokwadi chekushanda kwemagetsi kwakakwana.

Chimwe chinhu chakakosha kufunga nezvacho ndechekuti zvinhu zvisina halogen zvinopisa sei. Kufambiswa kwekupisa kwezvinhu izvi kunogona kusiyana neFR -4 laminates dzechinyakare, izvo zvinogona kukanganisa kugona kwePCB kubvisa kupisa. Kuti udzivise kupisa zvakanyanya uye kuchengetedza kushanda kwakakodzera, kuongorora kupisa kwakaringana kunokurudzirwa kuti uve nechokwadi chekuti kutonhora kwakakwana kunochengetwa mukati mePCB.

Mechanical hunhu senge coefficient yekupisa kwekuwedzera (CTE) uye modulus inogonawo kusiyana pakati pehalogen-isina laminates. Misiyano iyi inogona kukanganisa kurongeka kwePCB uye kuvimbika. Kuti uwedzere kuita uye hupenyu hurefu, zvinokurudzirwa kuita bvunzo dzekuita izvo zvinotarisa iyi misiyano yemakina.

Chekupedzisira, kudhiraivha uye kuchinjika kunopa akasarudzika matambudziko ane halogen-isina zvinhu. Zvishandiso izvi zvinogona kuda akagadziridzwa zvibooreso zvimiro, kushandiswa kwemadiki mabhiti ekuchera, kana kuderera mitengo yekudya panguva yekugadzira. Pamusoro pezvo, kuve nechokwadi chekuti solder mask adhesion inogona kudikanwa kuwedzera kugadzirira kwepamusoro kana kushandiswa kwevanosimudzira. Kubvunzana nemugadziri wako wePCB kuti uwane gwara pane izvi zvinhu uye kuita bvunzo dzekuvimbika kwenguva refu, senge Nguva-Inotsamira Dielectric Breakdown (TDDB) bvunzo, inogona kubatsira kusimbisa kukodzera uye kusimba kwezvinhu zvitsva-isina halogen mumashandisirwo chaiwo.

Halogen-Yemahara Laminate uye Prepreg Sarudzo

Yakasiyana-siyana yehalogen-isina resin masisitimu yakagadziridzwa seeco-inoshamwaridzika dzimwe nzira dzechinyakare halogenated laminates. Izvi zvinhu zvinopa akasiyana zvivakwa uye maitiro ekuita:
