Yintoni iMozulu yokuNxhathisa ukusebenza kweeElastomers ezahlukeneyo

Yintoni iMozulu yokuNxhathisa ii-elastomers ezahlukeneyo?

Ekukhetheni irabha enokumelana nezinto ezinokusetyenziswa kuso nasiphi na isicelo, kuyimfuneko ukuqonda iindlela ezahlukeneyo apho imozulu inokuchaphazela nayiphi na i-elastomer enikiweyo, eyona ixhaphakileyo:

-Ukukhanya kwelanga

-Ubushushu

-Ozone kunye ne-UV

-IiMeko zeMozulu eziNgentle

Butyl:

I-butyl iqhele ukusetyenziswa njengesiseko semathiriyeli ngenxa yokumelana okunamandla nokukhanya kwelanga, i-ozone kunye nokuguga kobushushu, kunye nezinye iipropathi eziyinika ukuxhathisa okukhethekileyo kwigesi kunye nokufuma (amanzi kunye nomphunga). I-Butyl ikwabonelela ngokuxhathisa okulungileyo kwi-asidi edibeneyo kunye ne-alkalis kunye nokuguquguquka okuhle kobushushu obuphantsi.

EPDM:

I-EPDM iyahambelana neentlobo ezininzi zezinye izinto xa imveliso idibanisa ngokuthe ngqo kwisicelo esithile kwaye ibonisa ukuchasana kwemozulu ebalaseleyo, okwenza kube yinto ekhethekileyo yokukhetha ukusetyenziswa xa iimveliso okanye amacandelo abonakaliswe kwizinto. I-EPDM inamandla okuxhathisa imiphumo ephazamisayo ye-ozone, i-oksijeni, ukushisa, kunye nemozulu, kunye noluhlu lweekhemikhali kunye ne-acids dilute kunye ne-alkali.

IHypalon:

IHypalon sesinye sezona zixhobo zixhathisayo kwimozulu ekhoyo ngokukhanya kwelanga kunye nokukhanya kwe-UltraViolet eneziphumo ezimbalwa ezibi kwiipropathi zayo zomzimba. Ngelixa ii-elastomers ezininzi ziqala ukuthotywa ngokugxininiswa kwe-ozone ye-1 ppm emoyeni, i-Hypalon ihlala ingachatshazelwa kugxininiso oluphezulu njengenxalenye e-1 kwiindawo ezili-100 zomoya. Kubuchule obubalaseleyo bokwamkela umbala kukwathetha ukuba iikhompawundi zeHypalon ezinemibala azipheli ekuvezweni okwandisiweyo kukukhanya kwelanga kunye ne-UV.

Ipolyurethane:

Xa kuthelekiswa nezinye ii-elastomers, i-Polyurethane inika ukuxhathisa okugqwesileyo kwe-abrasion kunye namandla okuqina, zombini ezo ziguqulela ukusebenza okuphezulu kuzo zonke iimeko zemozulu, kunye nezinto ezibonelela ngokuchasana kakuhle kwe-Ozone kunye namaqondo obushushu asebenzayo asezantsi -50 ° C kwaye phezulu ukuya kuma-90°C.

I-Silicone:

I-Silicone ithathwa ngokubanzi njengesixhobo esisebenza ngeendlela ezininzi ekwazi ukumelana neoksijini, i-ozone, ukukhanya kwe-UV, ukwaluphala, imozulu, kunye namaqondo obushushu agqithisileyo.

Kwiimeko ezininzi, ukhetho lwemathiriyeli kufuneka lube lulungelelwano kunye nenani lezinto ezahlukeneyo eziza kudlala kubandakanya neenkcukacha zokusetyenziswa komntu, ungalibali uqoqosho lwemeko ethile.
