Ibintu bijyanye na butyl reberi byongeweho.Iyi mitungo nayo ibaho muri butyl adhesive
(1) Ikirere
Umuvuduko wo gukwirakwiza gaze muri polymer ujyanye nibikorwa byubushyuhe bwa molekile ya polymer.Amatsinda ya methyl kuruhande mumurongo wa butyl reberi itunganijwe neza, igabanya ibikorwa byubushyuhe bwa molekile ya polymer.Kubwibyo, gaze ya gaze ni mike kandi gukomera kwa gaze nibyiza.
(2) Guhindura ubushyuhe
Butyl rubber vulcanizates ifite ubushyuhe bwiza kandi budahinduka.Rubberi ya sulfure yamashanyarazi irashobora gukoreshwa mu kirere igihe kirekire kuri 100 ℃ cyangwa ubushyuhe buke.Ubushyuhe bwo gukoresha bwa resin vulcanized butyl rubber irashobora kugera kuri 150 ℃ - 200 ℃.Ubushyuhe bwa ogisijeni yubushyuhe bwa butyl reberi ni ubwoko bwangirika, kandi gusaza biroroha.
(3) Kwinjiza ingufu
Imiterere ya molekulire ya butyl reberi ni ngufi ihuza imigozi ibiri, kandi ubwinshi bwikwirakwizwa ryuruhererekane rwa methyl matsinda ni nini, bityo ikaba ifite ibimenyetso byiza byo kwakira ibinyeganyega ningufu.Ibiranga kwisubiramo biranga butyl ntibishobora kurenga 20% mubushuhe bwagutse (- 30-50 ℃), byerekana neza ko ubushobozi bwa reberi ya butyl yakira imirimo yubukanishi iruta izindi reberi.Umutungo wangirika wa butyl rubber kumuvuduko mwinshi wo guhindura ibintu uba mubice bya polyisobutylene.Ahanini, ntabwo byatewe nubushyuhe bwo gusaba, urwego rwo kudahaga, imiterere yibirunga hamwe nimpinduka.Kubwibyo, butyl rubber yari ibikoresho byiza byo gukingira amajwi no kugabanya kunyeganyega muri kiriya gihe.
(4) Ubushyuhe buke
Umwanya wububiko bwa butyl rubber urunigi ni spiral.Nubwo hariho amatsinda menshi ya methyl, buri tsinda ryamatsinda ya methyl yatatanye kumpande zombi za spiral iranyeganyezwa ninguni.Kubwibyo, urunigi rwa butyl reberi iracyoroheje cyane, hamwe nubushyuhe buke bwikirahure hamwe na elastique nziza.
(5) Ozone no kurwanya gusaza
Kwiyongera kwinshi kwa butyl reberi ya molekile ituma igira ozone nyinshi kandi ikarwanya gusaza ikirere.Kurwanya ozone birenze inshuro 10 ugereranije na reberi karemano.
(6) Guhindura imiti
Imiterere yuzuye ya butyl rubber ituma igira imiti myinshi idahinduka.Rubber ya butyl ifite imbaraga zo kurwanya ruswa nyinshi kuri acide organic organique na acide organic.Nubwo idashobora kurwanya aside irike cyane, nka acide ya nitric na acide sulfurike, irashobora kurwanya acide idafite okiside hamwe na aside irike ya aside irike, hamwe nigisubizo cya alkali hamwe nigisubizo cyo gukiza okiside.Nyuma yo gushiramo 70% acide sulfurike mu byumweru 13, imbaraga no kuramba kwa butyl rubber ntibyatakaye, mugihe imikorere ya reberi karemano na reberi ya styrene butadiene yagabanutse cyane.
(7) Imikorere y'amashanyarazi
Gukwirakwiza amashanyarazi hamwe na corona birwanya butyl reberi biruta ibya reberi yoroshye.Ijwi rirwanya inshuro 10-100 kurenza irya reberi yoroshye.Ihoraho rya dielectric (1kHz) ni 2-3 naho imbaraga (100Hz) ni 0.0026.
(8) Kwinjiza amazi
Igipimo cyo kwinjira mumazi ya butyl reberi ni gito cyane, kandi igipimo cyo kwinjiza amazi mubushyuhe busanzwe kiri munsi yizindi reberi, 1 / 10-1 / 15 gusa byanyuma.
