Fili - shi ne mai dogara da kariya na kayan aiki daga matsananci yanayin

A lantarki injiniya, mu sau da yawa haɗu da kalmar "fili". Mene ne wannan? Fili - shi ne wani insulating fili cewa a lokacin da yin amfani da shi ne wani ruwa, sa'an nan warke ba a cikin abun da ke ciki kaushi. A fili ba ya rasa da kaddarorin a zazzabi kewayon daga -50 zuwa +200 digiri Celsius, shi ne resistant zuwa radiation for impregnation, zuba nodes, rediyo sassa, lantarki kariya ga buga kewaye allon kuma su gyara da waje tsoma (inji, thermal, sinadaran, vibration), musamman a maƙiya yanayin. Bayan duk, da yanayi a karkashin abin da ta yi aiki lantarki da kuma lantarki na'urorin da apparatuses ne da nisa daga dakin gwaje-gwaje. Wannan low zafin jiki na Far Arewa, da kuma high zafi na wurare masu zafi da sauyin yanayi, da kuma na abokan gaba yanayi na sarari, da sauransu. D. All na sama da aka tilasta zane injiniyoyi kare amfani kan daidai da danshi m coatings ninkawa kayan for potting da encapsulation aka gyara da kuma kayan aiki. Mafi sau da yawa amfani da wannan manufa biyu-bangaren garwayayye.

By da kaddarorin mahadi kasu kashi:

- impregnation.

- lantarki.

- simintin.

- Na roba.

- plasticized roba.

- wani low kwayoyin nauyi plasticizer.

Impregnating fili - a fili cewa da ake amfani da impregnation na windings na Motors da kuma inji.

Insulating, bi da bi, ya kasu kashi:

- thermoset (ba laushi bayan curing). Wadannan sun hada da epoxy, polyester da sauran resins.

- thermoplastic (laushi kan dumama) - bitumens waxy dielectrics, thermoplastic polymers (polystyrene, polyisobutylene).

Ciko fili - wani abun da ke ciki na cika cavities na USB kwalaye, kazalika da sealing a lantarki da inji kuma na'urorin.

Insulating cakuda sanya daga methacrylic esters, ana amfani da duka da impregnation da kuma zaben 'yan wasa. Irin wannan mahadi bayan curing a zazzabi na 70-100 digiri Celsius (da musamman hardener, wannan bakin kofa da aka saukar zuwa 20 digiri), suna thermosetting kuma za a iya amfani da a yanayin zafi daga -55 zuwa +105 digiri. Suna amfani ga impregnation iri-iri na juyawa kayan aiki (da nada Tuddan Motors da kuma al.) Wanda ya bada tasiri kariya da lantarki,.

Potting fili dangane da bitumen a kan matakin da zafi juriya (105 ° C) nasa ne da aji "A". Yana da mafi zafi juriya epoxy da silicone mahadi.

Na roba plasticized roba garwayayye sun samu musamman aikace-aikace. Yau ne Popular fili ga siffofin. Saboda an yi shi m silicone kyawon tsayuwa da daban-daban jeri. Da zazzabi tsarin mulki na fili ya kai wani iyaka ga + 200 ° C, shi ne mai tsanani a kan 250 ° C ba da shawarar saboda polymer an hallaka Hadin.

A halin yanzu shi samar daban-daban maki na mahadi, kowanne daga abin da ya samu da ikon yinsa, kuma ya mallaka Properties hali na shi.

Mafi m ya zama epoxy fili - a polymer da low shrinkage, m dielectric halaye da kuma high mannewa. Yana iya yin aiki a cikin yanayi na dindindin nakasawa. Epoxy resins suna yadu amfani da daban-daban kayan aiki, shigarwa, Tsarin. Wadannan garwayayye ne jituwa tare da sauran oligomers da kuma hanzarta su hardening da hadawa da wasu mahadi. A drawback na epoxy guduro ne a low zafin aiki, wanda ya sa ya yiwuwa a yi amfani da shi a cikin wani dabara da aiki a wani wajen matsananci yanayi.

Rungumar, zamu iya cewa da amfani da mahadi qara aiki AMINCI da kara da sabis rai na na'urorin lantarki da kuma lantarki da kayan aiki, tabbatar da sealing da kuma kariya game da vibration, na taimaka kare masu amfani daga lantarki a halin yanzu.
