Izakhiwo
I-Chlorobutyl (CIIR) kanye ne-bromobutyl (BIIR) elastomers ayi-copolymers ye-halogenated isobutylene (Cl, Br) kanye nenani elincane le-isoprene elinikeza amasayithi angagcwele unsaturated for vulcanization.Ukwethulwa kwe-bromine noma i-chlorine kuthuthukisa ukumelana ne-ozone, isimo sezulu, amakhemikhali, nokushisa.Lokhu, nokho, kuza ngezindleko zokufakwa kukagesi nokumelana nomswakama.
Kokubili i-bromobutyl (BIIR) ne-chlorobutyl (CIIR) inomgogodla ogcwele we-isobutylene.Womabili ama-elastomers anezimfanelo eziningi zenjoloba ye-butyl ejwayelekile okuhlanganisa igesi ephansi kanye nomswakama ukungena, ukudambisa okuhle kokudlidliza, izinga lokushisa eliphansi lokushintsha kwengilazi, ukumelana okuhle kakhulu nokuguga nesimo sezulu, kanye nokuguquguquka okubanzi okuguquguqukayo.
Ukwethulwa kwe-chlorine noma i-bromine kukhulisa ukunamathela kumarabha, nezinsimbi, kuthuthukisa ukuhambisana namarabha e-diene emixubeni, futhi kunikeza amazinga aphezulu kakhulu okuphulukisa, okungukuthi inani eliphansi lokwelapha elidingekayo.Ngaphezu kwalokho, i-halogenated butyl ingavuthwa ngokuhlanganyela ngenjongo evamile yama-elastomers ane-unsaturation ephezulu, njengenjoloba yemvelo, i-polybutadiene, nerabha ye-styrene-butadiene, kuyilapho igcina isakhiwo somgogodla esigcwele kakhulu.
Womabili amarabha ane-halogenated anezakhiwo ezifanayo kakhulu.I-chlorine, nokho, inyusa ukusebenza kabusha kwezindawo zokwelapha okuholela ekwelapheni okusheshayo kanye nokunamathela okuthuthukisiwe kuma-elastomer angagcwele.
Izinhlelo zokusebenza
Kokubili amarabha e-butyl ne-halobutyl ahlinzeka ngokugcinwa kwengcindezi yokwehla kwamandla emali okuhle kakhulu.Ziyinketho ekahle yamashubhu angaphakathi amabhayisikili, amaloli, namathayi ezimboni nezolimo.Eqinisweni, amarabha e-butyl ane-halogenated angamarabha e-butyl asetshenziswa kakhulu kuma-liner angaphakathi amathayi.Amarabha e-halobutyl nawo asetshenziselwa amapayipi, ama-seal, ama-membrane, ama-linings ethangi, amabhande okuthutha, izingubo zokuzivikela kanye nemikhiqizo yabathengi, njengama-ball bladders empahleni yezemidlalo.Ama-halobutyl ngokuvamile ayisinqumo esihle lapho kudingeka ukumelana kahle namakhemikhali, isimo sezulu, kanye ne-ozone.
Sebenzisa
Isetshenziswa kabanzi ekwenzeni imikhiqizo ehlukahlukene yenjoloba engamelana nowoyela, ama-gaskets ahlukene amelana nowoyela, ama-gaskets, imikhono, ukupakishwa okuthambile, ipayipi eliguquguqukayo, ukuphrinta nokudaya amarola enjoloba, izinto zenjoloba yekhebula, njll. sekuyimpahla ebalulekile yokunwebeka emotweni. , ezondiza, i-petroleum, ukukopisha nezinye izimboni.
