pusu Posted December 21, 2013 Share Posted December 21, 2013 Unde se gaseste pasta din aceasta? Si cum se numeste? Quote Link to comment Share on other sites More sharing options...
validae Posted December 21, 2013 Share Posted December 21, 2013 Nu e polietilena sub forma de bara? Se topeste cu un pistol cu rezistenta de incalzire inclusa.Daca e relativ moale la intepare este polietilena.Daca e dura, e un fel de rasina Epoxy.

em2006 Posted December 21, 2013 Share Posted December 21, 2013 Nu e polietilena sub forma de bara? ....Nu e. Circuitul din poza e de la un invertor de sudare (probabil Gys, ori Awelco). Plasticul acele aplicat la cald cu pistolul nu e bun la circuite de putere, care se pot incalzi, caci se blegeste si se-nmoaie la temperaturi mai mari.Conditia care se pune pentru compoundul care se va aplica dupa depanare in zona mentionata este sa prezinte rezistenta de izolatie buna (tensiunile avute in vedere fiind de ordinul 600-1000V) si sa nu se inmoaie la cald. In lipsa rasinii epoxidice originale, se poate folosi silicon sanitar transparent, bine uscat, adica sa nu alimenteze circuitul decat a2a zi dupa aplicare, cand materialul e bine uscat.Inainte de aplicarea siliconului, e bine sa se sprayeze un lac electroizolant, de exemplu Urethan 71 sau Plastik 70 (mai slabut), de asemenea bine uscat in prealabil.

pusu Posted December 21, 2013 Author Share Posted December 21, 2013 Nu e polietilena si e foarte tare. Ma intereseaza ce material e acela si daca-l putem gasi si noi undeva. Quote Link to comment Share on other sites More sharing options...
Spitfire Posted December 21, 2013 Share Posted December 21, 2013 Poate fi o rasina epoxy bicomponent, se poate folosi si ceva gen poxypol. Quote Link to comment Share on other sites More sharing options...
pusu Posted December 21, 2013 Author Share Posted December 21, 2013 N-as crede ca poxypol sa aiba calitati de izolator necesare in electronica...Asteptam sa vedem si alte pareri. Quote Link to comment Share on other sites More sharing options...
wally_gatter Posted December 21, 2013 Share Posted December 21, 2013 ceva rasina epoxidica o fi.. eram si eu interesat de asa ceva cand am vrut sa incasetez niste montajele in ceva transparent ,deci cautam o rasina transparenta.. asta pare tot o rasina.

pusu Posted December 22, 2013 Author Share Posted December 22, 2013 E si foarte tare (e totusi foarte putin cauciucoasa nu e dura ca un poxipol) si foarte greu de indepartat. Nu a lucrat nimeni cu maglaváis din asta? icon_jook Quote Link to comment Share on other sites More sharing options...
danb1974 Posted December 22, 2013 Share Posted December 22, 2013 Poti sa cauti de exemplu la tme la workplace equipment > chemical products > encapsulating materialsDar s-ar putea sa nu-ti placa preturile Quote Link to comment Share on other sites More sharing options...
pusu Posted December 22, 2013 Author Share Posted December 22, 2013 da, am gasit la http://www.tme.eu/en/katalog/workplace- ... _order=ASC dar astia's chiar bolunzi la preturi Quote Link to comment Share on other sites More sharing options...
danb1974 Posted December 23, 2013 Share Posted December 23, 2013 tme au preturi super okVrei sa rizi de unul singur, te duci la farnell. Dar na, farnell are mult mai multe pe stoc si livreaza mai repede. Quote Link to comment Share on other sites More sharing options...
briobit Posted January 25, 2014 Share Posted January 25, 2014 De ce nu il intrebi pe colgul Arcadius ca in rasina din aia isi trage bobinele la eolienele pe care le face, eu cred ca e la fix ce ai nevoie Quote Link to comment Share on other sites More sharing options...
Ionut Pavel Posted January 25, 2014 Share Posted January 25, 2014 Cred ca se numeste "potting compound" (poate sa fie epoxy, PU, etc...). Se gaseste la farnell-> Chemicals & Adhesives->Potting Compounds. Quote Link to comment Share on other sites More sharing options...
