PCB - ntoni na? Iimpawu kunye neempawu.

Le PCB ibizwa iindidi zeplastiki elaminethiweyo, iziziba lwesamente. Thermosetting emahlamvini zokwenziwa bakhonza element njengento ebophelelayo. Kwaye akukho kubaluleke kangaka, oko kuthathwa PCB. Yintoni na, bekulula ukuqonda nkqu le nkcazelo

Ezinye parameters neempawu

Kuxhomekeka semvelo a textolites ifayibha yahlulwe kumaqela eziliqela.

1. Bazaltotekstolity ngokusekelwe imicu abangelwe.
2. Uglerodotekstolity carbon.
3. Asbotekstolitov kunye imicu asbestos.
4. Fibreglass imicu iglasi kweentlobo ezahlukeneyo.
5. Organotekstolity okwenziwe kunye imicu zokwenziwa.
6. Eneneni textolites Imicu cotton

Kukho ezinye iintlobo. Twill, satin, plain - iintlobo uyiluke, ezahluke kwayo ngokwabo. Ngamana ube mninzi umphezulu ezahlukileyo, ubukhulu, inani zixhobo nganye iyunithi ubude kweli cala lokuluka kunye weft nelaphu, isakhiwo kunye Ebubanzini vulu okanye bemlandela. Kukho iteknoloji ekhethekileyo avelise PCB. Yintoni na, sele kufunyenwe.

Ukuba amandla interlayer kufuneka kolube phezulu, isicelo multilayer uhlobo ilaphu. Ngamanye amaxesha kukho iimveliso apho Imicu zenziwe iindidi ezininzi izinto.

Okunye loo inqaku?

Ngaba kwakhona technology lokuvelisa efanelekileyo, imali kunye neempawu Umatshini, iimpawu laphu, uhlobo imicu - i parameters yokufumanisa oko iimpawu kuya kuba PCB ngokwayo. Ke inkqubo yemveliso, ilwela isiseko emva komnye okanye ngokubhijela ukuboniswa zomzimba xa kwiimveliso ifomu mandrel isicelo yokubopha. Ngefoyile ye PCB iveliswa ngendlela efanayo. Ngaphezu koko kukho umqolo. Ngaphezu koko, textolite iipleyiti, Iizilebhu okanye amaxwebhu kufuneka baye machining.

Ezahlukahlukeneyo kwi ekwakhiweni kusenokungabikho kuphela laphu kodwa kokuxhuma, ezidlala indima ukuba ukumitha le lokufaka. Thermosetting emahlamvini zokwenziwa badla ukufeza le ndima, ngefoyile ye PCB - akukho ngaphandle.

Kwimfaneleko, kunye nezinye iparameters

Kukho inani leempawu izinto ezinjalo nje PCB. Ukuba kulula ukuqonda ukusuka inkcazelo iimpawu zayo.

1. Indlela yokuqhuba ishishini uluhlu lobushushu - degrees -40 ukuya 105, ukuba rhoqo yangoku ezimalunga 50 Hz, igcinwe ukufuma isalamane.
2. PCB - yokwambathisa elungileyo, ukuze lube sisixhobo sele kushishino amandla yezamandla.
3. Lula machining.
4. amandla High.
5. mninzi Low.
6. A 'ngumlingani ka aphantsi kunobunye.

ulwazi olongezelelweyo

Textolite amaphepha ezisetyenziswa kwiinkalo ezininzi zobomi. Kunokuba zesakhiwo, antifriction, zochuku, umbane, kunye ubushushu ngekhompyutha.

Ngeendlela ezininzi, oku kunegalelo ubuchule sokutshintshela lula imithwalo mechanical, ezinkulu kakhulu. Ngoko ke ukusetyenziswa ngakumbi kwande kuyo kwicandelo lobunjineli yombane. Ngenxa ye-PCB zenziwa kunye iindawo ezahlukeneyo ngeenjongo constructional.

Izicelo kunye namathuba amatsha

Ekuveliseni umsebenzi osontiweyo, ezitshibilizayo iibheringi, bushings kusetyenziswa PCB zokuhomba. Oko na ziyalandeleka ngaphandle izichazi ezizodwa. Iipanele zokuthotywa imicu lungabonakala le nto.

Ekudluliseni, xa iindlela ukusasazwa injini ezahlukeneyo, gearbox ngokufuthi etsobhileyo ubukho ngonyuka nezixhobo zezindlu ezisekelwe izinto ezifana PCB. Ixabiso yahlukile. Elements of iimpompo centrifugal, zokusila ibhola, turbines ke iibheringi textolite. PCB buyisela ngempumelelo getinaks njenge material ukulungiselela ukuveliswa kwiindawo zombane. Izizathu PCBs of PCB kwenza ntoni elektroniki. Ukongeza, xa itumente namhlanje oko PCB iba sisiseko imveliso kwezixhobo - application wayo kakhulu ngesiquphe.

A kangako kumabanga

Kukho iindidi PCB, ekuthiwa asboplastikom kunye wachacha ngokwahlukeneyo. Kweli langatye-ukumelana kwaye ukwazi ukumelana ubushushu ukuya degrees 250 impahla ixesha elide. elana imichiza Lubonakala, iimpawu ubushushu zombane umhlwa. Uhlobo Umatshini kunye lokufaka ubukhulu becala imisela ukuba iya kuba yintoni na iimpawu imveliso ethile. Umzekelo, uxhathiso eliphezulu asidi izinto adlulisela asbestos anthophyllite. kwenziwa kwaye iqondo indlela yokuzalisa nabo babe negunya nefuthe lazo kwi parameters ezikhoyo. Kwimeko nganye, yonke into uzimisele ngamnye, emva kwesi umkhondo ngokwahlukeneyo.
