Brominated Butyl Rubber (BIIR)

Tsanangudzo Pfupi:

Brominated butyl rubber (BIIR) isobutylene isoprene copolymer elastomer ine inoshanda bromine.Nekuti brominated butyl rabha ine main cheni iyo yakanyatsozadzwa nebutyl rabha, ine akasiyana ekuita maitiro ebutyl polymer, senge simba repamusoro remuviri, yakanaka vibration inonyorovesa kuita, kuderera kupenya, kuramba kuchembera uye mamiriro ekunze kuchembera.Iko kugadzirwa uye kushandiswa kwehalogenated butyl rubber yemukati liner yakawana razvino radial tire mune zvakawanda zvinhu.Kushandiswa kwemapolymers akadaro mumushonga wemukati wemukati wevhiri kunogona kuvandudza kushanda kwekumanikidza, kugadzirisa kunamatira pakati pemukati wemukati uye chitunha uye kugadzirisa kusimba kwevhiri.

Product Characteristics

Butyl rabha mutsara wepolymer ine isobutylene semuviri mukuru uye ishoma isoprene.Paketani huru yebutyl rabha molecule, rimwe nerimwe boka remethylene, kune mapoka maviri emamethyl akarongwa muchimiro chakatenderera chakatenderedza cheni huru, zvichikonzera chipingamupinyi chikuru, zvichiita kuti mamolecular chimiro chebutyl rubber compact uye molecular cheni ishanduke zvishoma. .Nekudaro, inoitawo butyl rabha yakanakisa mukusimba kwemhepo, inomira pekutanga pakati pemarubha ese.

Kuwedzera kune yakanakisa kusimba kwemhepo, butyl rabha vulcanizates zvakare ine yakanakisa kupisa kupisa.Sulfur vulcanized butyl rabha inogona kushandiswa mumhepo kwenguva yakareba pa100 ℃ kana kuderera zvishoma.Tembiricha yebasa rebutyl rabha yakasvibiswa neresin inogona kusvika 150-200 ℃.Iko kupisa kweokisijeni kuchembera kwebutyl rabha ndekwerudzi rwekuora, uye kuchembera kunowanzo kupfava.Nekuda kwekudzika kwakadzika kwema molecular cheni yebutyl rabha uye inert kemikari reaction, butyl rabha ine kupisa kwakanaka uye oksijeni kuchembera.

Trade mode: brominated butyl rabha ndicho chigadzirwa chedu chemumiririri.Izvo zvishoma odha inosvika makumi maviri matani.

Application

1. Kushandiswa mumotokari yemotokari uye vhiri remotokari yemagetsi:
Butyl rabha ine yakanakisa kupisa kupisa uye kuramba kubvarura.Machubhu emukati (kusanganisira midhudhudhu nemabhasikoro) akagadzirwa nebutyl rabha anogona kuramba achichengetedza simba rakanaka uye kubvaruka mushure mekuratidzwa kwenguva refu kune nharaunda inopisa, izvo zvinoderedza njodzi yekuputika panguva yekushandiswa.Iyo butyl rabha yemukati chubhu inogona kuramba ichivimbisa hupenyu hwepamusoro hwematoyi uye kuchengetedzeka pasi pemamiriro ekushisa kwakanyanya kana pasi pemamiriro ekunze.Iyo diki kubvarura inogona kuderedza saizi yegomba uye kuita kugadzirisa kwebutyl rabha yemukati chubhu kuve nyore uye nyore.Iyo yakanakisa oxidation kuramba uye ozone kuramba kwebutyl rabha inoita kuti butyl rabha yemukati chubhu ive yakanakisa kudzikisira kuramba, uye kusimba kwayo uye hupenyu hwesevhisi zviri nani pane yakasikwa rabha yemukati chubhu.Kudzikira kwakanyanya kwemhepo yebutyl rabha inoita kuti chubhu yemukati yakagadzirwa nayo ichengetedzwe panguva chaiyo inflation pressure kwenguva yakareba.Uku kuita kwakasarudzika kunogonesa tayi rekunze chubhu kupfeka zvakaenzana uye inovimbisa hupenyu hwekorona hwakanakisa.Wedzera hupenyu hwesevhisi yevhiri rekunze, wedzera kugadzikana uye kuchengetedzeka kwekutyaira, kuderedza kutenderedza kuramba, uyezve kuderedza kushandiswa kwemafuta kuzadzisa chinangwa chekuchengetedza simba.

2. Kushandisa muchivharo chebhodhoro rezvokurapa:
Medical bottle stopper chinhu chakakosha rabha chigadzirwa chekuisa chisimbiso uye kurongedza chinobatana zvakananga nemishonga.Kuita kwayo uye hutano hunokanganisa zvakananga kubudirira, kuchengeteka, kugadzikana kwehutano uye nyore kwezvinodhaka.Makoraki ekurapa anowanzo itwa sterilized pasi pekupisa kwakanyanya uye kudzvanywa kwemamiriro ezvinhu kana mune akasiyana ma disinfectants, uye dzimwe nguva anofanirwa kuchengetwa kwenguva yakareba pasi pemamiriro ekushisa akaderera.Naizvozvo, pane zvakaomesesa zvinodiwa pamakemikari ezvivakwa, emuviri mechanical zvivakwa uye biological properties yerabha.Sezvo chivharo chebhodhoro chiri kutarisana zvakananga nemushonga, chinogona kusvibisa mushonga nekuda kwekupararira kwechinhu chinobviswa mubhodhoro chivharo mumushonga, kana kuderedza basa remushonga nekuda kwekutorwa kwezvimwe zvikamu mumushonga. pedyo nechivharo chebhodhoro.Butyl rabha haingove nekupinda kwakaderera chete, asiwo ine yakanakisa oxidation kuramba, asidhi uye alkali kuramba, kupisa kupisa uye kukuvara kwemakemikari kuramba.Mushure mekushandiswa kwebutyl rabha bhodhoro chivharo, fekitori yemishonga inogona kurerutsa iyo sub packaging process, shandisa yakavhurika aluminium cap, kubvisa yekuisa chisimbiso uye kuderedza mutengo, uye zvakare inogona kufambisa jekiseni kushandiswa.

3. Mamwe maapplication:
Pamusoro pekushandiswa kuri pamusoro, butyl rabha ine zvinotevera mashandisiro: (1) lining yemakemikari emidziyo.Nekuda kwekunakisisa kwayo kemikari inodzivirirwa, butyl rabha rave iro rinofarirwa zvinhu zvekugadzira corrosion rining yemakemikari emidziyo.Kuzvimba kwevhoriyamu yebutyl rabha mune zvakasiyana zvinonyungudutsa zvakaderera, chinova chimwe chezvikonzero zvakakosha nei butyl rabha richishandiswa mundima iyi.(2) Zvipfeko zvinodzivirira uye zvinhu zvinodzivirira.Kunyangwe akawanda epurasitiki zvinhu zvine kunaka kwekuzviparadzanisa uye kuita kwekudzivirira, chete elastic zvinhu zvinogona kupa kufunga kune kuchinjika kunodiwa kune yakaderera permeability uye yakagadzika zvipfeko.Nekuda kwekuderera kwayo kupinza kune zvinwiwa uye magasi, butyl rabha inoshandiswa zvakanyanya muzvipfeko zvekudzivirira, ponchos, zvivharo zvekudzivirira, masks egasi, magirovhosi, rabha overshoes uye bhutsu.

Kugadzirira

Pane nzira mbiri dzekugadzira dzakajairwa butyl rabha: slurry nzira uye mhinduro nzira.Iyo slurry nzira inoratidzirwa nekushandisa chloromethane seyakadzika uye mvura-alcl3 sekutanga.Pakudzika kwekushisa kwe - 100 ℃, isobutylene uye zvishoma isoprene inopinda cationic copolymerization.Iyo polymerization process inoda kushandiswa kwezvinokonzeresa.Kuti uvandudze kushanda kwezvigadziriswe, zvinodikanwa kushandisa cocatalysts kuti utange polymerization muzviitiko zvakawanda.Tekinoroji yekugadzira inodzorwa nemakambani ekunze eAmerica nemakambani eGerman.Iyo nzira yekugadzira yebutyl rabha neslurry nzira inonyanya kusanganisira matanho mana: polymerization, kunatsa chigadzirwa, kudzokorodza uye kettle kuchenesa.Iyo nzira yekugadzirisa yakagadziriswa neRussia taoriati synthetic rubber kambani neItaly kambani.Iyo tekinoroji ficha ndeyekuti yakaoma yealkyl aluminium chloride uye mvura inoshandiswa sekutanga kucopolymerize isobutene uye diki isoprene muhydrocarbon solvent (senge isopentane) patembiricha ye - 90 kusvika - 70 ℃.Iyo huru maitiro ekugadzirwa kwerabha yebutyl nenzira yemhinduro inosanganisira kugadzirira, kutonhora, polymerization yeinitiator system uye zvakasanganiswa zvinongedzo, kusanganiswa kwerubha mhinduro, degassing uye kubvisa, kudzoreredza uye kunatswa kwekunyungudika uye kusagadziriswa monomer, mushure mekurapa rabha, nezvimwe. maitiro makuru ekubatsira anosanganisira firiji, kuchenesa reactor, kugadzirira kwekuwedzera, nezvimwe.
