Lolomiina gaosi lolomi laupapa matagaluega (mulimuli ane taua i le PCB) O oloa na faʻaaogaina faʻapisinisi talu mai le 1948 ma ua amata ona aliali mai ma ua faʻaaogaina lautele i le 1950s. O le alamanuia PCB masani o se tagata faigaluega-ogaoga alamanuia ma lona faʻatekinolosi malosi e maualalo ifo nai lo o le semiconductor alamanuia. Talu mai le amataga o le 2000, o le semiconductor alamanuia na faasolosolo lemu ese mai le US ma Iapani i Taiwan ma Saina. E oʻo mai i le taimi nei, ua avea Saina ma taʻutaʻua gaosi oloa PCB i le lalolagi, sili atu ma le 60% o le PCB galuega faatino a le lalolagi.

Meafaigaluega faafomaʻi:

O le alualu i luma i aso nei i saienisi faʻafomaʻi e mafua uma mai i le vave atinae o le eletise eletise. Tele masini faʻafomaʻi (faʻataʻitaʻiga, mita mita, faʻatulagaina o fua o le fatu, fua o le vevela, eletise eletise, eletise MRI, X-ave, CT scan, masini toto -faʻavae mo le faʻaaogaina e le tagata lava ia. Nei PCBS e masani ona puʻupuʻu ma i ai tamaʻi laʻititi foliga coefficients. Density sensors o lona uiga o le tuʻuina o tamaʻi mea SMT i laʻititi laʻititi PCB. O nei masini faʻafomaʻi e laʻititi, faigofie e ave, mama ma faigofie ona faʻagaioia.

Masini tau alamanuia.

PCBS o loʻo lautele faʻaaogaina foi i falegaosimea, falegaosimea ma tuaoi laʻau. O nei matata eseese o loʻo i ai masini eletise maualuga e faʻataʻitaʻiina e le malosi galue faʻasolosolo e manaʻomia tele nei. Ina ia faia lenei, o le pito i luga vaega o le PCB ua ufiufi ma le mafiafia vaega o apamemea, lea, e le pei o faigata eletise PCBS, o loʻo aveina ai le taimi nei e oʻo atu i le 100 amperes. E taua tele lenei i faʻapolokalameina pei o uelo uʻamea, tele taʻavale afi avetaʻavale, taʻitaʻifau-asini maa fualaʻau, le malamalama lelei i le ie vavae mo le militeri pisinisi ma lavalava.

Le malamalama

I moli, o le lalolagi o agaʻi agai i le malosi lelei fofo. These halogen bulbs are rare now, but now we see LED lights and high-intensity leds around. O nei tamaʻi tamaʻi laʻititi maua maualuga malamalama pupula ma o loʻo faʻamau i luga ole alumini-faʻavae PCBS. Alumini ei ai le meatotino o mitiia vevela ma susulu atu i le ea. O le mea lea, ona o le maualuga o le paoa, o nei alumini PCBS e masani ona faʻaaogaina i taʻamilosaga lamepa TAITAIINA o auala feololo ma le maualuga paʻu uila.

Taavale ma malae vaalele

Another application of PCBS is in the automotive and aerospace industries. O se mea masani iinei o le toe faʻafouina mai le feʻaveaʻi o vaʻalele poʻo taʻavale. O le mea lea, ina ia faʻamalieina nei gatete malosi-maualuga, o le PCB avea fetuʻutuʻu.

O le mea lea, faʻaaoga se PCB taʻua o le Flex PCB. E mafai e le PCB fetuʻunaʻi ona tatalia le tete ma le mamafa o le pauna, ma faʻapea ona faʻaititia ai le mamafa atoa o le vaʻa. Nei fetuutuunai PCBS mafai foi ona fetuʻunaʻi i se avanoa vaapiapi, o se tele aoga foi. O nei fetuutuunai PCBS tautua o ni fesoʻotaʻiga, faʻafesoʻotaʻiga, ma mafai ona faʻatasia i vavalalata Avanoa, e pei o tua laupapa, lalo dashboard, etc. E mafai foi ona faʻaaoga se tuʻufaʻatasiga o PCBS maumaʻa ma fetuutuunai (PCBS maumaututū-fetuutuunai).

Mai le tufatufaina o le apalai alamanuia, tagata faʻaaoga eletise na fuafuaina mo le sili ona maualuga vaega, e oʻo atu i le 39%; O komepiuta na maua mo le 22%; Fesoʻotaʻiga 14%; Industrial controls and medical equipment accounted for 14 per cent; Automotive electronics accounted for 6%. Puipuiga ma malae vaʻalele numera mo le 5%, malae vaʻalele ma vailaʻau masini ma isi fanua i ai maualuga manaʻoga mo PCB saʻo.

PCB e lautele faʻaaogaina ona e tele ona tulaga ese tulaga lelei, lea e mafai ona aoteleina e pei ona taʻua i lalo.

1. Maualuga-maualuga.

Faʻatasi ai ma le faʻaleleia atili o le tuʻufaʻatasia o le tuʻufaʻatasiga tuʻufaʻatasia ma faʻapipiʻiina tekonolosi, maualuga-density PCBS mafai ona atiaʻe.

2. Maualuga faʻatuatuaina.

E ala i le faʻasologa o asiasiga, suʻega ma le matua o suʻega, e mafai ona mautinoa le PCB e galue faʻatuatuaina mo se taimi umi.

3. Tusiaina.

Mo ituaiga uma o PCB faʻatinoina (eletise, tino, vailaʻau, masini, ma isi) manaʻoga, mafai ona faʻataʻitaʻia e ala i le mamanu, faʻavasegaina ma isi auala e ausia lolomi laupapa laupapa taimi fuafuaina e puʻupuʻu, maualuga lelei.

4. Tupuolaola.

E ala i ona po nei pulega, tulaga faʻapitoa, fua (aofaʻi), otometi ma isi gaosiga mafai ona faia e faʻamautinoa le tumau o le lelei oloa.

Faʻamaoniga.

O se suʻesuʻega maeʻaeʻa metotia, faʻataʻitaʻiga tulaga faʻataʻitaʻi, eseese suʻega mea faigaluega ma mea faigaluega ua maeʻa faʻataʻitaʻia ma faʻailoa PCB oloa mo ogatasi ma tautua olaga.

6. Faʻatasiga.

O oloa PCB e le gata e faʻafaigofieina faʻapotopotoga faʻapitoa o vaega eseese, ae faʻafaigofieina foi otometi ma tele gaosiga.

I le taimi lava e tasi, PCBS ma faʻapotopotoga vaega o vaega eseese e mafai ona faʻaputuputuina i ni lapoʻa vaega, polokalama, poʻo ni masini atoa.

7. Tumau.

O oloa PCB ma vaega o fonotaga ua faʻamautuina aua ua mamanuina ma gaosia i se tulaga faʻapitoa.

I lenei auala, a maeʻa le faiga, e mafai ona vave, faigofie ma fetuʻunaʻi suia, ma vave toe faʻaleleia le galuega o le tautua tautua.
