NBR ke eng?

Nitrile butadiene rabara (NBR), ke copolymer ea acrylonitrile le butadiene monomer polymerization, haholo-holo e hlahisoang ke mocheso o tlaase oa emulsion polymerization, ho hanyetsa oli e ntle haholo, ho hanyetsa ho apara ho phahameng, ho hanyetsa mocheso o motle, ho khomarela ka matla. Mefokolo ea eona ke ho hanyetsa mocheso o tlase, ho hanyetsa ozone, ts'ebetso e mpe ea insulation, elasticity e tlase.

Ka lebaka la ho hanyetsa oli le thepa e ntle ea 'mele le mochini, NBR e sebelisoa haholo ha ho etsoa lihlahisoa tse fapaneng tsa oli tse hanyetsanang le oli joalo ka lihlahisoa tsa rabara. Tse kang O-ring, gasket, hose le mafura tanka lera rabara, khatiso rolara, tanka lera, insulate fatše boto, oli manganga sole, likarolo rabara ka thata, lesela barbotage, phala khoele sireletsang lera, pompo impeller le terata sheath, sekgomaretsi, lijo ambalaji filimi, litlelafo rabara le masimo a mang. Linaheng tse ling tse sebelisoang haholo-holo ho lifofane, likoloi, khatiso, tlhahiso ea masela le mechine, joalo-joalo Ka nts'etsopele ea mefuta e fetotsoeng ea NBR, tebello ea kopo ea rabara ea nitrile butadiene e atolosoa. Kakaretso ea sehlooho: ho etsa li-tubing tsa mafura, lesela la mafura, tiiso ea oli, peipi ea oli, likarolo tsa rabara e hanyetsanang le oli le ho kopana le oli le mefuta eohle ea lihlahisoa. Rabara ea Nitrile e sebelisoa haholo ho etsa lihlahisoa tse hanyetsanang le oli, joalo ka phala ea oli, theipi, filimi ea rabara le mokotla o moholo oa oli, hangata o sebelisetsoa ho etsa mefuta eohle ea lihlahisoa tse sa keneng tsa oli, joalo ka O-ring, tiiso ea oli, sekotlolo sa letlalo, diaphragm, valve, bellows, hose ea rabara, litiiso, foam, jj.

Hobaneng ha rabarabrake hosee na le mohala o lohiloeng oa nylon?

Ho sebelisa nylon interlayer le chlorinated butyl rabara e le sebopeho sa ka hare le ka ntle, ho ka hlahisa mofuta o mocha oa hose ho thibela ho tsoa ha khase ea freon, ho etsa hore phala e be matla.

Lintho tse tsofalang tsa rabara:

1. Oksijene: Oksijene ka rabara e nang le limolek'hule tsa rabara karabelong ea mahala ea radical chain, break ea molecular chain kapa crosslinking e feteletseng, e leng se bakang phetoho ea thepa ea rabara.

2. Ozone: Ts'ebetso ea lik'hemik'hale tsa Ozone ho feta oksijene e phahame haholo, e senya ho feta, hape ke ho senya ketane ea molek'hule, empa ketso ea ozone holim'a rabara e nang le deformation ea rabara e fapane.

3. Mocheso: Ntlafatsa sekhahla sa phallo ea oksijene le ts'ebetso ea ts'ebetso ea oxidation, e le ho potlakisa sekhahla sa karabelo ea oksijene ea rabara, e leng ntho e tloaelehileng ea botsofali - botsofali ba oksijene ea mocheso.

4. Leseli: Ha leqhubu la leseli le le khuts'oane, le matla le ho feta. Ke matla a phahameng a ultraviolet a senyang rabara. Ntle le ho baka ka kotloloho ho robeha le ho hokahanya ha liketane tsa limolek'hule tsa rabara, rabara e monya matla a leseli mme e hlahisa li-radicals tsa mahala, tse qalang le ho potlakisa ts'ebetso ea ketane ea oxidation, e bitsoang "light outer layer crack".

5. Metsi: karolo ea metsi e na le likarolo tse peli: rabara ka pula ea moea e kolobileng kapa e kolobisitsoeng ka metsing, e leng bonolo ho e senya, sena se bakoa ke lintho tse qhibilihang ka metsing ka lihlopha tsa rabara le tsa hydrophilic le likarolo tse ling ka ho ntša metsi le ho qhibiliha, hydrolysis kapa ho monya le mabaka a mang. Haholo-holo tlas'a phello e fapaneng ea ho qoelisoa metsing le ho pepeseha sepakapaka, timetso ea rabara e tla potlakisa. Leha ho le joalo, maemong a mang, metsi ha a senye rabara, ebile a na le phello ea ho lieha ho tsofala.

7. Oli: Ha ho sebelisoa mokhoa oa ho kopana ka nako e telele le oli ea oli, oli e ka kenella ka har'a rabara ho etsa hore e ruruhe, e leng se fellang ka ho fokotseha ha matla a rabara le lisebelisoa tse ling tsa mechine. Oli ka etsa rabara ho ruruha, hobane oli ka rabara, hlahisa limolek'hule diffusion, e le hore vulcanized rabara netweke sebopeho fetoha.
