Izvo zvakakodzera zvimiro zvebutyl rubber zvinowedzerwa.Izvi zvinhu zvakare zviripo mubutyl adhesive
(1) Kupinda kwemhepo
Kumhanya kwekuparadzira kwegasi mupolymer kune hukama nebasa rekupisa kwemamorekuru epolymer.Iwo epadivi methyl mapoka ari mubutyl rabha mamorekuru cheni akarongedzerwa, izvo zvinodzikamisa basa rekupisa kwema polymer mamorekuru.Naizvozvo, iyo gasi permeability yakaderera uye gasi kusimba kwakanaka.
(2) Kusiyana kwekushisa
Butyl rabha vulcanizates ine yakanakisa kupisa kupisa uye kusachinja.Sulfur vulcanized butyl rabha inogona kushandiswa mumhepo kwenguva yakareba pa100 ℃ kana kuderera zvishoma.Tembiricha yekushandiswa kweresin vulcanized butyl rabha inogona kusvika 150 ℃ - 200 ℃.Iko kupisa kweokisijeni kuchembera kwebutyl rabha ndekwerudzi rwekusvibisa, uye maitiro ekuchembera ari kupfava.
(3) Kutora simba
Iyo molecular chimiro chebutyl rabha ipfupi yemabhondi maviri, uye kupararira density yeside chain methyl mapoka akakura, saka ine hunhu hwakanaka hwekugamuchira vibration uye simba rekuita.Iyo rebound maitiro ebutyl rabha haapfuure makumi maviri muzana mukati mehupamhi tembiricha renji (- 30-50 ℃), izvo zvinonyatsoratidza kuti kugona kwebutyl rabha kugashira mabasa emakanika kwakakwirira kune mamwe marabha.Iyo inonyorovesa midziyo yebutyl rabha pakumhanya kwepamusoro deformation ndeyemukati muchikamu che polyisobutylene.Kusvika pamwero mukuru, haina kukanganiswa nekushisa kwekushandisa, dhigirii rekusaturation, vulcanization chimiro uye shanduko yefoma.Naizvozvo, butyl rabha chaive chinhu chakanakira kuvharidzira ruzha uye kuderedza vibration panguva iyoyo.
(4) Low tembiricha pfuma
Chimiro chenzvimbo yebutyl rabha molecular chain is spiral.Kunyangwe paine akawanda methyl mapoka, maviri ega emapoka emamethyl akapararira pamativi ese espiral anozungunuswa nekona.Naizvozvo, iyo butyl rabha molecular cheni ichiri yakapfava, ine yakaderera girazi shanduko tembiricha uye yakanaka elasticity.
(5) Ozone uye kuramba kuchembera
Iyo yakakwira saturation yebutyl rabha molecular chain inoita kuti ive nepamusoro ozone kuramba uye nemamiriro ekunze kuramba kuchembera.Iyo ozone resistance inenge ka10 yakakwirira kudarika yerabha rechisikigo.
(6) Kusagadzikana kwemakemikari
Iyo yakakwira saturated chimiro chebutyl rabha chinoita kuti ive nepamusoro makemikari invariance.Butyl rabha ine yakanakisa corrosion resistance kune akawanda inorganic acids uye organic acids.Kunyangwe isingadziviriri kune concentrated oxidizing acids, senge nitric acid uye sulfuric acid, inogona kuramba isiri oxidizing acids uye yepakati concentration oxidizing acids, pamwe nealkali mhinduro uye oxidation kudzoreredza mhinduro.Mushure mekunyura mu70% sulfuric acid kwemavhiki gumi nematatu, kusimba uye kurebesa kwebutyl rabha hakuna kumborasika, ukuwo mabasa erabha rechisikigo uye styrene butadiene rabha akaderedzwa zvakanyanya.
(7) Basa remagetsi
Iyo yemagetsi insulation uye corona kuramba yebutyl rabha iri nani pane iyo yerabha iri nyore.Iyo vhoriyamu resistivity ndeye 10-100 nguva yakakwira kupfuura iyo yerabha iri nyore.Dielectric constant (1kHz) ndeye 2-3 uye simba factor (100Hz) i0.0026.
(8) Kunwa mvura
Mwero wekupinda kwemvura webutyl rabha wakadzikira zvakanyanya, uye mwero wekunyura kwemvura pane yakajairika tembiricha yakaderera pane yeimwe rabha, chete 1 / 10-1 / 15 yekupedzisira.
