Laminates: Properties kunye Izicelo

Iinkqubo ngendlela, izixhobo ezintsonkothileyo kunye nezakhiwo, leyo bayanda iimfuno zokusebenza, esebenzisa izixhobo ezikhethekileyo edityanisiweyo. Ngokuqhelekileyo, akukho jikelele kunye neemveliso ezizodwa kakhulu yenzelwe ukusebenza kwiimeko nobushushu nokufuma kakhulu. Ezi isolators ziquka laminates zilandelayo: getinaks, PCB, iglasi ifayibha, kwakunye zokuguqulwa zabo. Ngokusebenzisa indibanisela amandla kunye nokuthintela ubushushu thermal mpawu zisasilela ezinjalo ingasetyenziswa kumasebe ajongene yayo injongo eyenzelwe, izixhobo kunye nezixhobo.

Ukusetyenziswa kwe zeplastiki elaminethiweyo

LwaseNtshona Koloni ziba ukusetyenziswa zezi Iipholima nto zahlukahlukene kakhulu. Le kushishino lomatshini sixhobo, nobuchwepheshe eyama kunye namashishini yokuvelisa, kwakunye namashishini zokwakha kunye imichiza. Naphi na apho kufuneka ukusetyenziswa ngendlela kombane, ukusetyenziswa izinto ezinjalo. Oku akuthethi ukuba bathethe yokusebenza kwabo. It yaphawula uluhlu olubanzi zokuguqulwa, leyo ninikele laminates. Ukusetyenziswa ubume of version nganye sasijoliswe kwiinkalo ezithile. Umzekelo, getinaks efanelekileyo ukwenza amacandelo zexabiso eliphantsi in izixhobo zombane, kunye nezinto weenkuni ngaplastiki ngokusebenzisa isakhiwo ngqongqo ezisetyenziswa iindlela zobugcisa. umda kakhulu enabileyo kwinkqubela-PCB, ejongana kunye noshishino zombane, kunye izakhiwo petrochemical, kwakunye isixhobo entle.

Yintoni ukuvelisa laminates?

Le laminate i material edityanisiweyo esekelwe - a Umatshini polymeric. Ukuze ukomeleza isiseko ezisebenzayo lendlele ikwasetyenziswa ngokwemaleko akhiwe abalwazi lokufaka. Ngamanye amazwi, le laminates - ukuhlanganiswa izakhi ezibini imelwe Umatshini kunye lokufaka. Njengokuba kubalulekile kuqala kusetyenziswa nentlaka zokwenziwa. It zingenziwa ipholiyesta, epoxy, phenol-formaldehyde kunye nezinye izinto. Kwakhona eqhelekileyo ukusetyenziswa Iipholima, phakathi leyo - abicah kunye nezinto fluoropolymer. Ke ukuze ligcwalise, ngoko ke umsebenzi unokwenza izinto zemveli ekrwada njengoko kwimicu asbestos nephepha kwincindi.

Iinkcukacha Laminates

Xa version zakudala le laminate kuyinto material sheet apho ibekwe phezu uhlobo iiphaneli zibheke oluqhelekileyo. iintlobo zelaphu azixhaphakanga. Sheet ubukhulu ekungabonini ukusuka mm 0.4 ukuya ku-50, kuxhomekeka ezahlukeneyo kunye nokwakheka yokwambathisa. Kwakhona, iindidi zobungakanani ubude nobubanzi. panel fiberglass Standard, umzekelo, abe umlinganiselo iparameters 1200x1000 mm. iimpawu Ukusebenza balihlutha laminates, bavakalisa ukukwazi ukumelana neemeko ezahlukeneyo lobushushu. Kwakhona, inyoba avareji yeplastiki ekuqhelekileyo ezinjalo nemiqulu engama -60 ° C ku 120 ° C. Ngokuxhomekeke ukubandakanywa modifiers ezongezelelweyo, le range yandiswe.

izakhiwo fiberglass

Ukusebenza kwalo weplastiki kumiselwa nokubunjwa kwayo, nto leyo equka kwiiseli ezininzi yeglasi ngaplastiki kunye kwezobuchwepheshe ngokucinezela ashushu. Le Umatshini kule meko a thermosetting epoxy-candelo. Ngokweempawu ezingundoqo afakwa olu hlobo laminates ziquka ukumelana ubushushu phezulu, ukhuselo neziphumo ezibi ukufuma kunye namandla ngoomatshini. Ngaphezu koko, ngokungafaniyo zisasilela ezininzi, iglasi ifayibha yi izinto nokusingqongileyo eyandisa intsimi isicelo yayo. Nomtsalane yayo emarikeni igalelo kumgangatho ophezulu Heating elide.

iipropati Micarta

Enye indlela eqhelekileyo laminate, esetyenziswa izinto zokwambathisa ezikhoyo. Iimpawu zokusebenza labalandeli lichaza zeendawana iphepha iphathwa kunye nomxube izakhi okanye epoxy nentlaka.

Le plastiki akakwazi ndingaqhayisa indibanisela iimpawu ezifana amandla ngoomatshini kunye nokukwazi ukumelana amaqondo obukhulu. Kunjalo oluthambileyo ngokwemiqathango yokujongwa kuvumela ukwenza isiseko iibhodi yesekethe eprintiweyo bonke ubukhulu. Ngaphezu koko, lo ngowona laminates ifikelelekayo, yaye oko kwakhokelela ukusebenzisa kwabo abaninzi yomculo. Ukusuka izinto ezinjalo, ingakumbi ngenxa ukuvelisa isitampu zolungiselelo amacandelo izicelo yabathengi ombane aphantsi.

iipropati PCB

Amanqaku kwakheka amalaphu yomqhaphu ngokucinezela kunye thermosetting Umatshini phenolformaldehyde Ukongeza iqela kushushu. Loo isicelo wasinika laphu isiseko PCB amandla compressive ophezulu, kunye kobulembu. Isiseko lula kusingathwa yi ukubhola, ukulisika bexhentsa. Oku kwabangela izinga layo izinto ezisetyenziswa kwinkqubo imveliso izinto phantsi kwempembelelo imithwalo zombane kunye mechanical.

Kulo mzekelo, kukho iindidi eziliqela, ezo yahlulwe laminates yorhwebo. Iimpawu ze kudidi lokuqala zibonakaliswa kwindlela anda ngayo bodwa ombane, nto leyo evumela ukusetyenziswa eziphathekayo emoyeni, yaye eolini transformer. Udidi lwesibini uphawuleka eziphuculweyo iipropati oomatshini, ngoko ke amalungu zeplastiki zenziwe eli qela kunokwenzeka ukuba babuyele umthambo. Kukho utshintsho ezikhethekileyo PCB, yenzelwe ukusetyenziswa kwiqondo lobushushu ephakamileyo.

Iimpawu laminates weenkuni zeplastiki

Umahluko omkhulu noshowo zokwambathisa izixhobo ze olu hlobo isetyenziswa njenge iinkuni lokufaka kwisiseko. Ngokukodwa, edityanisiweyo neemakhishithi zabo ngokwenene intw ngokomyalelo 0.3-0.6 mm. Kunye Iipholima of zendalo izinto inxibelelane ngokusebenzisa nentlaka resole. Ngenxa yoko, izinto edityanisiweyo luba ngcono iipropati anti-ukukhuhlana, ukumelana kumajelo ndlongondlongo kunye lingonakali, nto leyo abakwazi ukumelana ezinye laminates.

Iimpawu, isicelo kunye neemfuno zentsebenzo kulo mzekelo kubangelwa yindibanisela iseti iimpawu. Wavakalisa iimpawu eziza kusetyenziswa isixhobo ukhuseleko kuphela emzimbeni, kodwa ukumelana ukunyakama, iimpawu Heating kunye nozinzo nokulondolozwa kwi lobushushu ultra-phantsi kwi -250 ° C. Ngokumalunga ukusetyenziswa, iinkuni-laminates sihlanganiswe kakuhle kwi indlela leeyunithi ukukhuhlana, iibheringi, iivelufa hydraulic kunye nezinye iinkqubo zobugcisa.

isiphelo

zisasilela Modern zaye ekuqaleni zaphuhliswa ukuvelisa izinto eziphakamileyo-amandla ukuba akwazi endaweni aluminium ezithile zesinyithi. Ngenxa yoko, icandelo lokwakha uyakwazi ukufumana enye indlela ngumnyhadala yemveli ngokohlobo kweentonga fiberglass. Ngenxa yoko, le laminates luba replacement ezilungileyo insulators bemveli. Bona azisetyenziswa apho kuthathwe ukuba kusetyenziswe yoboya izimbiwa okanye panels isivalo, kodwa niche olulodwa, nto leyo iimpawu ngokwaneleyo eqhelekileyo hlobo, bethatha baphonononga Iipholima ezintsha sekhombuya. Noko ke, loo nto ngaphandle kwaye isahlakalo elizayo insulators ezinjalo ukusetyenziswa ingxenye ekhaya. Kuyo nayiphi na imeko, nobuhlobo lwendalo fiberglass ezinokuba negalelo.
