Laminates: Properties uye Applications

The kuputira hurongwa, dzakaoma mano uye zvivako, izvo zvakawedzera operative zvinodiwa, vachishandisa chaiyo anoumbwa nevazhinji zvinhu. Kazhinji, hazvina waifarirwa zvikuru kushandiswa zvigadzirwa raireva kushanda kupisa uye mwando ezvinhu. isolators izvi zvinosanganisira zvinotevera laminates: getinaks, pcb, girazi faibha, uyewo avo okunatsiridza. Kuburikidza mubatanidzwa simba uye kumbogadzirwa kuti mudziye unhu chinoumbwa yakadaro inogona kushandiswa pezvivako anokonzera ayo aida chinangwa, mano uye zviridzwa.

Kushandiswa laminated mapurasitiki

The chakarondedzera raishandiswawo Polymers idzi siyana chaizvo. Izvi muchina chokushandisa maindasitiri, uye avhiyesheni ano, uye kugadzira Mazinga, uyewo pakuvaka uye zvemakemikari Mazinga. Pose zvaida kushandiswa magetsi kuputira, kushandisa zvinhu zvakadaro. Izvi hazvisi kutaura pakawanda yavo. Yakati-siyana okunatsiridza, izvo kupa laminates. Kushandiswa Zvinoumba neimwe shanduro vakaomerera zvatichakurukura. Somuenzaniso, getinaks zvakakodzera kuita rweruzhinji zvinoumba mune magetsi mano, uye matanda-laminated zvinhu kuburikidza yakaoma maumbirwo kushandiswa michina zvigadziriswe. Zvikuru kwazvo yezvinoreva pcb, inotaura uye magetsi maindasitiri, uye petrochemical zvivako, uyewo kuva mudziyo wakanaka.

Chii kubudisa laminates?

The laminate chinhu chine zvinhu kunobva - a polymeric bhainda. Kuitira kusimbisa dzichipfekeka nechigadziko rinoshandiswawo akaturikidzana iri anowedzera filler. Nemamwe mashoko, laminates - wemishonga zviviri zvikuru zvinoriumba aimiririra bhainda uye filler. Somunhu rokutanga chirungiso akashandisa chakaita zvokugadzirwa nebwe. It zvinogona kuitwa polyester, epoxy, phenol-formaldehyde uye zvimwe zvinhu. Kazhinji kushandisa Polymers, ramakagadzwa - silicone uye fluoropolymer zvokuvakisa. Kana zvinodiwa, zvino basa anogona kuita zvetsika mbishi zvinhu sezvo asbestos uye cellulose bepa fibers.

Details of Laminates

Munguva klassiske shanduro yacho laminate ndiyo semucheka zvinhu izvo anoiswa pamusoro mhando kwakajairika nemamiriro aenzana. Ishoma jira mhando. Sheet ukobvu ingabva 0,4 kusvika 50 neMM, zvichienderana siyana uye insulator sezvamunoita. Uyewo, akasiyana-siyana hukuru pakureba uye upamhi. Standard Washington City Offices Panel Somuenzaniso, une avhareji parameters 1200x1000 mm. Kushanda unhu akagarwa laminates, akaratidza kukwanisa kukurira siyana tembiricha ezvinhu. Zvakare, paavhareji mukoridho kuti kwese epurasitiki neeSultan dzakadaro kubva -60 ° C kusvika 120 ° C. Subject kuti unyorwe yakawedzerwa modifiers, chikuva ichi inogona kuwedzerwa.

ehupfumi Washington City Offices

Chokupika epurasitiki ichi ndezvipi sezvamunoita kwayo, izvo zvinosanganisira akaturikidzana wandei regirazi laminated pamwe zvinopisa kudzvanya rwokugadzira. The bhainda hazvisi chinhu thermosetting epoxy-chikamu. Inokosha ehupfumi izvo rusununguko urwu mhando laminates zvinosanganisira yakakwirira kupisa nemishonga, kudzivirirwa nemigumisiro ine unyoro uye simba zvokuimba. Uyezve, kusiyana chinoumbwa zhinji, girazi faibha ndiyo zvinhu chinhu zvakatipoteredza noushamwari kuti anowedzera chikumbiro munda wayo. Uye kukwezva kwayo pamusika inobatsira kuti yepamusorosoro dielectric yepamusoro uye mukurumari.

zvivako Micarta

Chimwe zvakafanana kusiyana pamusoro laminate, iro rinoshandiswa sezvo insulating zvinhu. The vanoshanda ehupfumi rinoumba rinotsanangura bepa substrate zvakaipa pamwe musanganiswa phenolic kana epoxy Inogadzirwa nemasiridzi anobuda mumiti.

mapurasitiki Izvi hazvigoni kuzvirumbidza mubatanidzwa unhu hwakadai simba zvemaziso uye kukwanisa kukurira tembiricha akanyanyisa. Asi nyore kufurirwa panyaya kubudiswa inobvumira kuumba hwaro yakadhindwa redunhu namapuranga hukuru zvose. Uyezve, ndiyo yakachipa pashiri laminates, uye zvakaita kuti avo kushandiswa kwakapararira chiridzwa. Kubva zvinhu zvakadaro, zvikurukuru nokuti pakuburitsa ndokutsika zvinoriumba logistics yakaderera voltage nevatengi zvikumbiro.

zvivako pcb

Material rakaumbwa nedonje micheka zvinopisa kudzvanya ane thermosetting bhainda phenolformaldehyde Kuwedzera boka. Kuti chikumbiro akagovera Mucheka chawo pcb mukuru simba compressive, uye kusimba. Hwaro nyore kupatsanurwa nokuda kuchera, achicheka uye tsika. Izvi zvakakonzera kwayo zvinhu unhu kushandiswa pakuburitswa kwacho zvinhu zviri pasi pokudzora magetsi uye nomuviri zvinorema.

Muchiitiko chino, pane mhando dzakawanda, izvo vakakamura chinokosha laminates. Properties zviri muchikwata okutanga anotaurwa muchimiro yakawedzera magetsi nevamwe, izvo rinobvumira kushandiswa kwemashoko uye mudenga, uye mafuta transformer. Muchikwata yechipiri kunoratidzwa zvakawedzerwa zvemaziso ehupfumi, saka mapurasitiki zvikamu zviri akagadzirwa boka iri vangangowedzera kuenda muviri. Panewo chaiwo okunatsiridza pcb, akagadzirirwa kushandiswa panguva yakakwirira tembiricha.

The ehupfumi matanda-epurasitiki laminates

Musiyano mukuru STRUCTURAL kuti insulating zvinhu izvi mhando rinoshandiswa senzira huni filler nechimwe. Zvikurukuru, chinoumbwa machira ane ukanyatsotarisisa kuzadzikiswa Unorudzi 0.3-0.6 mm. With Polymers rwokuzvarwa zvinhu anotaura kuburikidza resole Inogadzirwa nemasiridzi anobuda mumiti. Somugumisiro, rinoumba zvinhu inofambidzana nani Anti-kukweshera ehupfumi, kuramba nehasha vezvenhau uye kunyange abrasion, izvo zvisingagoni kukunda mamwe laminates.

Properties, kushanda uye kuita zvinodiwa iyi nyaya inokonzerwa mubatanidzwa mumwe yakatarwa hwounhu. Ataurwa kushanda unhu acho haana wenyama kuchengeteka chete, asiwo mwando nemishonga, dielectric zvivako uye kuchengetedzwa kutsiga pa tembiricha Ultra-pasi pa -250 ° C. With Nezvokushandisa, huni-laminates vari revatema zvakanaka kupinda zvigadziriswe pakati kukweshera zviyero, mabheyaringi, hydraulic mavharuvhu nezvimwe michina nehurongwa.

mhedziso

Modern chinoumbwa vakanga pakutanga yakatanga kubereka mukuru-simba zvinhu zvinogona kutsiviwa zvimwe simbi alloys. Somugumisiro, kuvaka zvekutepfenyura anokwanisa kuwana imwe nzira kune zvetsika yechigarire muchimiro Washington City Offices tsvimbo. Uyewo laminates zvazova yokutsiva yakanaka zvetsika insulators. Havana kushandiswa apo kutorwa vanounganidza chicherwa shinda kana koko ukomba, asi unyanzvi hwakasiyana niche, zvisina kukwana kwakajairika zvechadenga ichi mhando, zviri kushingaira kuongorora Polymers itsva layered. Zvisinei, hazvina kunze uye remangwana panowanikwa insulators dzakadaro mudzimba kushandiswa chidimbu. Chero zvazvingava, kwezvakatipoteredza ushamwari Washington City Offices zvinogona kukonzera.
