Kuyini Ukusebenza Kokumelana Nesimo Sezulu kwama-Elastomer Ahlukene

Yikuphi Ukusebenza Kokumelana Nesimo Sezulu kwama-Elastomer Ahlukene?

Ekukhetheni irabha engamelana nezinto ezisetshenziswa kunoma yiluphi uhlelo lokusebenza, kuyadingeka ukuqonda izindlela ezahlukene isimo sezulu esingathinta ngazo noma iyiphi i-elastomer enikeziwe, evame kakhulu:

-Ukukhanya kwelanga

-Izinga lokushisa

- I-Ozone ne-UV

-Izimo Zezulu Ezingesihle

Butyl:

I-Butyl ivamise ukusetshenziswa njengesisekelo ngenxa yokumelana kwayo okuqinile nokukhanya kwelanga, i-ozone nokuguga kokushisa, kanye nezinye izakhiwo eziyenza imelane negesi kanye nomswakama (amanzi nesitimu). I-Butyl iphinde inikeze ukumelana okuhle nama-acids acwebileyo nama-alkali kanye nokuguquguquka okuhle kwezinga lokushisa eliphansi.

I-EPDM:

I-EPDM ihambisana nezinhlobonhlobo zezinye izinto lapho ukukhiqiza kuhlangana ngokuqondile nohlelo oluthile futhi kukhombisa ukumelana nesimo sezulu okuvelele, okuyenza ibe ukukhetha okunengqondo ukusetshenziswa lapho imikhiqizo noma izingxenye zivezwe ezintweni. I-EPDM inamandla okumelana nemiphumela eyonakalisayo ye-ozone, umoya-mpilo, ukushisa, nesimo sezulu, kanye nohlu lwamakhemikhali nama-asidi acwebileyo nama-alkali.

I-Hypalon:

I-Hypalon ingenye yezinto eziyisisekelo ezimelana nesimo sezulu ezitholakala kokubili ukukhanya kwelanga nokukhanya kwe-UltraViolet okunemiphumela embalwa engemihle ezimpahleni zayo ezibonakalayo. Nakuba ama-elastomer amaningi eqala ukuwohloka ngokugxila kwe-ozone engu-1 ppm emoyeni, i-Hypalon isalokhu ingathinteki ekugxilweni okufika phezulu njengengxenye eyodwa engxenyeni yomoya eyi-100. Ikhono elihle kakhulu lokwamukela ukwenziwa kombala kuphinde kusho ukuthi izinhlanganisela ezinombala ze-Hypalon azifihli ekuchazweni okunwetshiwe elangeni naku-UV.

I-polyurethane:

Uma kuqhathaniswa namanye ama-elastomer, i-Polyurethane inikeza ukumelana okuhle kakhulu kokuhuzuka namandla aqinile, womabili ahumushela ekusebenzeni okuphakeme kuzo zonke izimo zezulu, kanye nezinto ezinikeza ukumelana okuhle ne-Ozone namazinga okushisa asebenzayo afinyelela ku-50°C futhi njengoba kuze kufike ku-90°C.

I-Silicone:

I-Silicone ithathwa kabanzi njengento eguquguquka kakhulu imelana kakhulu nomoya-mpilo, i-ozone, ukukhanya kwe-UV, ukuguga, isimo sezulu kanye namazinga okushisa aphezulu.

Ezimweni eziningi, ukukhethwa kwempahla kudinga kube ukuvumelana okunezici eziningi ezahlukahlukene ezikhona ezihlanganisa ukucaciswa kokusetshenziswa komuntu ngamunye, kungakhohlwa umnotho wesimo esithile.
