Polyisobutylene CAS 9003-27-4
Polyisobutylene (PIB, CAS 9003-27-4) bụ polima linear jupụtara nke e nwetara site na cationic polymerization nke isobutylene monomer. Ọ naghị egbu egbu, ọ naghị esi isi, ọ kwụsiri ike nke ukwuu, ọ naghị ekwe ikuku banye n'ime ya nke ọma, ọ na-agbanwekwa nke ọma, ọdịdị ya na-agbanwe site na mmiri viscous → semi-solid → roba elastomer ka ibu molekul na-abawanye.
Na-eguzogide oke ike megide ịka nká na nkwụsi ike kemịkalụ
Njupụta nke agbụ ígwè zuru oke: na-eguzogide okpomọkụ, oxygen, ozone, ụzarị ultraviolet, asịd, alkalis na nnu, anaghị emebi emebi ma ọ bụ na-emebi emebi ruo ogologo oge
Nkwụsi ike nke okpomọọkụ: enwere ike iji ya ogologo oge na -50℃ ruo 150℃, yana ebe ọkụ dị elu na obere ọkụ
Oke ikuku siri ike + oke mkpuchi + obere permeability
Ike ikuku siri ike nke ukwuu: ihe mgbochi dị mma megide mmiri, gas na uzuoku, nke ka mma karịa roba nkịtị
Mkpuchi eletriki dị mma: nnukwu ike iguzogide olu, obere mfu dielectric, dabara adaba maka eriri / mkpuchi eletriki
Nchekwa na nke na-adịghị egbu egbu + ndakọrịta zuru oke
Nri FDA: anaghị egbu egbu, anaghị ewe iwe, enwere ike iji ya na chịngọm, ihe ịchọ mma, na ihe ndị na-enye ọgwụ
A na-ejikọta ya na hydrocarbons/roba/resin: ọ dị mfe ịgwakọta ma gbanwee, na-eme ka viscosity dịkwuo mma, na-agbanwe agbanwe ma na-eguzogide ihu igwe.
