Laminates: Properties thiab cov kev siv

Cov rwb thaiv tsev systems, complex pab kiag li lawm thiab lug, uas yog nce ua hauj lwm uas yuav tsum tau, siv tshwj xeeb puas cov ntaub ntawv. Raws li ib tug txoj cai, nws yog tsis universal thiab mas tshwj xeeb cov khoom meant ua hauj lwm nyob rau hauv huab cua kub thiab humidity tej yam kev mob. Cov isolators muaj xws li cov nram qab no laminates: getinaks, PCB, iav fiber, raws li zoo raws li lawv kho. Los ntawm ib tug ua ke ntawm lub dag lub zog thiab thermal rwb thaiv tsev zoo xws composites yuav siv tau nyob rau hauv cov lug lub luag hauj lwm rau nws npaj lub hom phiaj, pab kiag li lawm thiab seev.

Kev siv cov laminated yas

Lub spectrum ntawm kev siv ntawm cov polymers yog heev ntau haiv neeg. Qhov no tshuab cuab tam kev lag luam, thiab chaw ua dav hlua technology, thiab raug industries, raws li zoo raws li cov kev siv thiab cov tshuaj industries. Txhua qhov chaw uas yuav tsum tau siv cov hluav taws xob rwb thaiv tsev, siv xws cov ntaub ntawv. Qhov no yog tsis txhob hais lus ntawm lawv cov versatility. Nws sau tseg ib tug ntau ntawm cov kev hloov kho, uas qhia laminates. Kev siv cov muaj pes tsawg leeg ntawm txhua version yog teem rau tej cheeb tsam. Piv txwv li, getinaks haum rau ua tsawg-nqi cheebtsam hauv hluav taws xob pab kiag li lawm, thiab ntoo-laminated ntaub ntawv los ntawm ib tug txhav qauv siv nyob rau hauv cov kev mechanisms. Heev uas nws kim heev uas muaj lub PCB, uas npog thiab hluav taws xob kev lag luam, thiab petrochemical ceg, raws li zoo raws li ib tug zoo twj paj nruag.

Yuav ua li cas tsim laminates?

Cov laminate yog ib tug puas khoom raws li - ib tug polymeric phau ntawv. Nyob rau hauv thiaj li yuav ntxiv dag zog rau tej qhov puag yog tseem siv nyob rau hauv khaubncaws sab nraud povtseg nyob reinforcing muab tub lim. Nyob rau hauv lwm yam lus, lub laminates - lub ua ke ntawm ob feem sawv cev phau ntawv thiab muab tub lim. Raws li ib tug thawj muaj siv hluavtaws cob. Nws yuav ua los ntawm polyester, epoxy, phenol-formaldehyde thiab lwm yam. Nws tseem yog ib qho kev siv cov polymers, cov uas - silicone thiab fluoropolymer cov ntaub ntawv. Raws li rau lub filling, ces tus neeg ua hauj lwm muaj peev xwm ua tau cov tsoos raw cov ntaub ntawv raws li asbestos thiab cellulose ntawv fibers.

Paub meej ntawm Laminates

Nyob rau hauv lub classic version cov laminate yog ib daim ntawv khoom uas yog muab tso rau hauv hom pa txojkev panels. Tsawg ntau daim ntaub ntau ntau yam. Sheet thickness yuav thaj tsam li ntawm 0.4 mus 50 hli, nyob ntawm seb lub ntau yam thiab lub insulator muaj pes tsawg leeg. Tsis tas li ntawd, ib tug ntau yam ntawm ntau thiab tsawg pab nyob rau hauv ntev thiab dav. Standard fiberglass vaj huam sib luag, rau piv txwv, muaj ib nrab tsis 1200x1000 hli. Ua hauj lwm zoo muaj laminates, qhia cov muaj peev xwm los mus tiv ntau yam kub tej yam kev mob. Ib zaug ntxiv, qhov nruab nrab txoj kev hauv tsev rau cov raug yas xws yog hom twg los ntawm -60 ° C mus rau 120 ° C. Raws li cov kev xam nrog ntawm ntxiv modifiers, qhov no ntau yam yuav tsum txhab.

zog fiberglass

Cov kev ua tau ntawm no yas yog txiav txim los ntawm nws muaj pes tsawg leeg, uas muaj xws li ob peb khaubncaws sab nraud povtseg ntawm cov iav laminated ua ke los ntawm kub nias technology. Cov phau ntawv nyob rau hauv cov ntaub ntawv no yog ib tug thermosetting epoxy-tivthaiv. Yuav kom yooj yim zog uas yuav muab tej txiaj ntsim nrog hom laminates muaj xws li kub siab kuj, kev tiv thaiv los ntawm phiv los ntawm dej thiab txhua yam muaj zog. Ntxiv mus, tsis zoo li ntau composites, iav fiber yog ib tug phooj ywg environmentally cov khoom uas expands nws daim ntawv thov teb. Thiab nws attractiveness nyob rau hauv kev ua lag luam ua rau kom lub siab dielectric zoo thiab durability.

zog Micarta

Lwm ntau variation ntawm lub laminate, uas yog siv raws li insulating cov ntaub ntawv uas. Cov ua hauj lwm thaj chaw ntawm tus qhab sij ib daim ntawv substrate kho nrog ib tug sib tov ntawm phenolic los yog epoxy resins.

Qhov no yas yuav tsis khav ib tug ua ke ntawm xws zoo li txhua yam muaj zog thiab muaj peev xwm mus tiv nrog huab kub. Cuaj kaum malleable nyob rau hauv cov nqe lus ntawm kev tso cai rau kom lub hauv paus ntawm cov ntawv luam Circuit Court pab ntsa ntawm tag nrho cov ntau thiab tsawg. Nyob rau hauv tas li ntawd, nws yog ib qhov uas pheej yig laminates, thiab hais tias coj mus rau lawv ntau siv nyob rau hauv kev ntsuas. From xws li ib tug cov ntaub ntawv uas, nyob rau hauv particular rau cov stamped Cheebtsam logistics tsawg voltage neeg daim ntaub ntawv.

zog PCB

Khoom tsim ntawm paj rwb ntaub kub nias nrog ib tug thermosetting phau ntawv phenolformaldehyde tas li ntawd pab pawg neeg. Hais tias daim ntawv thov muab ib tug ntaub puag PCB siab compressive zog, thiab toughness. Hauv paus yooj yim tiav los ntawm drilling, txiav thiab stamping. Qhov no tshwm sim los nws cov khoom zoo siv nyob rau hauv qhuav txheej txheem hais tias yog nyob rau hauv tus ntawm hluav taws xob thiab cov neeg kho tshuab loads.

Nyob rau hauv cov ntaub ntawv no, muaj ntau ntau pawg, uas yog muab faib khoom laminates. Thaj chaw ntawm cov thawj qeb uas qhia nyob rau hauv daim ntawv uas muaj zog hluav taws xob kev rho tawm, uas tso cai rau kev siv ntawm cov khoom thiab nyob rau hauv cov huab cua, thiab nyob rau hauv lub transformer roj. Qhov thib ob qeb yog yus muaj los ntawm paub txhua yam khoom, yog li cov yas qhov chaw no yog ua los ntawm pab pawg neeg no yog cov yuav los tig mus rau ib ce muaj zog. Tseem muaj tshwj xeeb kev hloov kho PCB, tsim los siv rau ntawm kom kub.

Cov khoom ntawm ntoo yas laminates

Lub ntsiab yam ntxwv sib txawv ntawm insulating cov ntaub ntawv ntawm no hom yog siv raws li ib tug ntoo muab tub lim puag. Nyob rau hauv kev, puas los xij ntawm veneer complemented kev txiav txim ntawm 0.3-0.6 hli. Nrog polymers ntawm tej yam ntuj tso khoom communicates los ntawm resole resins. Raws li ib tug tshwm sim, tus qhab cov ntaub ntawv uas yuav zoo anti-kev sib txhuam zog, ua hauj txhoj puab heev cov xov xwm thiab txawm puas, uas yuav tsis withstand lwm laminates.

Properties, daim ntawv thov thiab kev kawm ntawv uas yuav tsum tau nyob rau hauv cov ntaub ntawv no yog vim muaj ib tug ua ke ntawm ib tug txheej ntawm cov yam ntxwv. Qhia ua hauj lwm zoo ntawm cov ntaub ntawv uas tsis tau tsuas yog lub cev kev ruaj ntseg, tab sis kuj ya raws kuj, dielectric zog thiab cov preservation stability ntawm ultra-tsawg ntsuas kub ntawm -250 ° C. Nrog hais txog kev siv, ntoo-laminates zoo mus rau hauv tus mechanisms ntawm kev sib txhuam units, bearings, hydraulic li qub thiab lwm yam kev systems.

Niaj hnub nimno composites tau chiv tsim los tsim high-zog khoom uas yuav hloov tau tej yam hlau alloys. Raws li ib tug tshwm sim, cov kev siv sector yog tau mus nrhiav lwm txoj kev mus rau ib tug tsoos fixture nyob rau hauv daim ntawv ntawm fiberglass rods. Nyob rau hauv lem, tus laminates tau ua ib tug zoo hloov tsoos insulators. Lawv tsis siv qhov twg coj mus rau pawg mineral wool los yog cork panels, tab sis tshwj xeeb niche, uas yog tsis txaus pa yam ntxwv ntawm no hom, muaj kev koom kawm ua tshiab fawm kib polymers. Txawm li cas los, nws yuav tsis cais thiab lub neej yav tom ntej tshwm sim ntawm xws insulators nyob rau hauv domestic siv ya. Nyob rau hauv txhua rooj plaub, lub tej friendliness ntawm fiberglass uas yuav pab.
