Pcb - chii? Properties uye unhu.

The pcb anonzi siyana pamusoro laminated mapurasitiki, zvakasimbisa micheka. Thermosetting chakaita zvokugadzirwa Inogadzirwa nemasiridzi anobuda mumiti vanoshumira kubatanidzwa maatomu akafanana. Uye hazvina kukosha, chii runoonekwa pcb. Chii, runako nyore kunzwisisa kunyange tsananguro

Vamwe parameters uye zvivako

Zvichienderana chii hunhu ane faibha textolites rakakamurwa mapoka akawanda.

1. Bazaltotekstolity pahwaro basalt fibers.
2. Uglerodotekstolity kabhoni.
3. Asbotekstolitov pamwe asbestos fibers.
4. Washington City Offices regirazi fibers pakubhadhara siyana.
5. Organotekstolity kubva chakagadzirwa uye chakaita zvokugadzirwa fibers.
6. Chaizvoizvo textolites fibers vari donje

Pane dzimwe mhando. Twill, satin, pachena - micheka marudzi, izvo vakasiyana filaments pachavo. Angava akasiyana pamusoro arambe achirema, ukobvu, nhamba filaments por chikwata urefu pakarukwa negwara uye weft rejira, marongerwo uye pakukora mavara kana kweva. Pane rinokosha Michina yaibereka pcb. Chii, hatina kare kuwana.

Kana interlayer simba anofanira kunge kunyanya yakakwirira, shandisa multilayer mhando jira. Dzimwe nguva pane zvigadzirwa umo fibers dzinoitwa anoverengeka siyana nezvinhu.

More pamusoro katsamba?

Zvakare akakodzera kugadzira michina, mari uye zvivako zviri bhainda, zvinoitwa chinokosha, yezvakaita fibers - the parameters kuziva chii unhu vachava pcb pachayo. Kana ari kugadzirwa muitiro, rinoshanda hwaro layering kana ichitenderera Kuratidzirwa zvinyama apo chimiro zvinogadzirwa mandrel akashandisa bhainda. Angazvidzvisa pcb anogadzirwa saizvozvo. Uyezve pane Kuumbwa. Uyezve, textolite ndiro, Slabs kana machira aifanira machine.

Kusiyanisa murwiyo kungava kwete chete chinokosha asiwo unobatanidza okunze, izvo nezvaanoita kuti impregnation yacho filler. Thermosetting chakaita zvokugadzirwa Inogadzirwa nemasiridzi anobuda mumiti kazhinji kuzadzikisa basa iri, foil pcb - hapana anosara.

On zvemashoko, uye dzimwe parameters

Kune akawanda unhu zvinhu zvakadai somunhu pcb. Kuti zviri nyore kunzwisisa kubva tsanangudzo zvachiri.

1. Kushanda tembiricha Range - -40 kusvika 105 madhigirii, kana mamiriro kakawanda vanenge 50 Hz, iri zvichachengetwawo hama mwando.
2. Pcb - chakanaka insulator, zvokuti anova chinokosha kushandisa simba uye simba indasitiri.
3. Shungu machine.
4. High simba.
5. Low arambe achirema.
6. A pasi coefficient kuti kukweshera.

mamwe mashoko

Textolite machira anoshandiswa munyaya zhinji muupenyu. Rinogona kuva STRUCTURAL, antifriction, kukweshera, magetsi, uye zvemagetsi insulating zvinhu.

Munzira dzakawanda, izvi zvinoita kuti kukwanisa uchatamisa zvemaziso mitoro, kunyange zvikuru zvakakomba nyore. Saka zviri kushandiswa kunyanya kwakapararira zvakatinakira magetsi ouinjiniya indasitiri. Pahwaro pamusoro pcb vari yaakaita zvakasiyana pagondobwe constructional zvinangwa.

Mafomu uye nemikana mitsva

Nokuti kugadzirwa maringi, zvishoma nezvishoma mumatope mabheyaringi, bushings vaishandisa Sora pcb. Chii chinogona kunzwisiswa kunyange pasina chinokosha maduramazwi. The depreciation ukomba uye rinoparadza kunogona kuonekwawo ichi zvinhu.

Nokubata, ari kuparadzirwa zvigadziriswe siyana michini, gearboxes kazhinji chaizvo kuvapo conical uye cylindrical giya tichifunga zvinhu zvakadai somunhu pcb. Mutengo rakasiyana. Zvezvidzidzo Centrifugal pombi, bhora zvigayo, turbines ndivo textolite mabheyaringi. Pcb angabudirira kutsiva getinaks ave mashoko pagadzirwe magetsi zvikamu. Chikonzero PCBs ose pcb kuitei Electronics. Uyezve, mune mutambo ano ndiko pcb inova hwaro kugadzirwa kwezvombo - ndiko kushanda kwayo zvikuru tisingazvifungiri.

A zvishoma pamusoro zvidzidzo

Pane zvakasiyana-siyana pcb, rinonzi asboplastikom uye akadzosawo yoga. murazvo nemishonga iyi uye rakasimba zvinhu anogona kutsungirira kupisa kusvika madhigirii 250. Anozivikanwa makemikari nemishonga, zvemagetsi insulating zvivako uye ngura. Mhando bhainda uye filler zvikuru anosarudza zvahuchaita vane zvinoitwa zvikuru chigadzirwa. Somuenzaniso, mukuru iine acid kuramba kuti zvinhu dzinopa anthophyllite asbestos. kugadzira uye dhigirii rokuzadza nzira vanogona nesimba simba ravo pamusoro aivapo parameters. Muchiitiko chimwe nechimwe, zvose akatsunga nomumwe, shure Mukaseti ino yoga.
