Mhinduro kwayo yakakwana yekupisa insulation: peek uye polyimide

Nhoo inopisa, iripo sedutu rekudzivirira, inochengetedza michina kubva pakupisa kwakanyanya. Inowanikwa mune dzakasiyana siyana zvinhu zvekushandisa, kusanganisira polyester, fiberglass, pepa kana vamwe mapurikisi, uye kunyange mainjiniya polymers akadai seyekuputika uye pi plastics. Hunhu hwezvinhu izvi zvinosiyana, asi zvese zvakagadzirirwa kusangana nezvinodiwa zvedu munzvimbo dzakasiyana siyana.

Nhofth nhoo inoshandiswa pamusoro pemidziyo ine akasiyana ukobvu uye kupisa-kupesana-kupokana cap, yaishandiswa kudzivirira tembiricha yakanyanya. Izvo zvinowanzogadzirwa nePolyester, fiberglass, pepa kana zvimwe zvekushandisa zveinjiniya.

Nei Sarudza Mapurasitiki Ezeki?

Peek iPurasitiki mapurasitiki ane midziyo yakanaka inoratidzwa mune dzakasiyana siyana dzevazhinji tembiricha uye makemikari ekuramba mashandisirwo. Kunyangwe iri yakanyanya kukwikwidza yepamusoro tembiricha, kuramba kwakanakisa kuita media, kana kugona kushandiswa muHupo hwemvura, peek anoratidza kuwanda kukurukura kwayo uye kunaka. Kunyangwe mumashizha, tsvimbo kana machubhu, peek inowanikwa mune yakanyanya kunaka fomu.

Zvakanakira kusarudza PI Polyimide zviri pachena:

PI seyenzi yeinjini inochengetera inopa basa rakakwana mune dzakasiyana siyana dzevazhinji tembiricha uye yemakemikari kuramba zvikumbiro. Izvo zvinyorwa zvine yakakwirira yepamusoro inobvumirwa tembiricha, yakasimba kwazvo uye ine nzvimbo yakanyanya yekunyungudika yemakore matatu celsius celsius. Kuwedzera kune izvi, inogona kugadzirwa mune dzakasiyana siyana mavara uye rinopesana nemakemikari mazhinji akadai seakials uye zvigadziko. Kazhinji, polyimide yakadzvanywa ndeyekunyanyisa, hairarame mashandiro emagetsi emagetsi ekutsamwa uye anogona kushandiswa muhutsinye hwemvura. Nekudaro, kune iyi application, pi mapurasitiki matombo anowanzo shandiswa.

Zvikomborero zvinotevera zvinogona kuwanikwa nekushandisa pi mapurasitiki mukusimbisa shrouds:

1. Pi ndeimwe yemapurasitiki ekudziya ekudzivirira anodzivirira.

2. Pi ine simba rakanakisa kune dzakasiyana-siyana eacids, zvigadziko, uye sol sol.

3. PI inoita zvakanaka pakupisa kwakanyanya, nekuenderera mberi kwekuwedzera kushandisa tembiricha kusvika kune 482 ° F (250 ° C)

4. PI ine manhamba akanaka kwazvo uye akaderera kunyorova (0.6% anopfuura maawa makumi maviri nemana) kunyangwe pakukwidziridzwa kupisa.

5. Pi iri FDA-inotenderwa kuonana Kwekudya uye zvekurapa zvishandiso, saka pi inogona kushandiswa chero kupi chikafu kana maratidziro emakirini anodikanwa.

6. PI Midziyo haina kupfava kana kuyerera pakupisa kwakanyanya.

7. PI Midziyo ine zvidiki zvidiki zvekupenya.

Sezvinoita zvinhu zvakanaka zvekupisa, vese vepa uye polyimide vane yavo zvakanakira, ivo vaviri vane kugona kwakanaka uye kusimba uye vane mitengo inonzwisisika, chero zvinhu zvinopa mhinduro yakakwana yezvinhu zvedu zvekunzwa. Nekutsvaga kumwe kutsvagisa, vatengi vakadzidza vane chokwadi chekutsvaga yakanakisa polyimide kana yezvinhu nhandaro yezvavakaita.
