Anti-mafuta emhuka nemuriwo chaiwoNeoprene (CR) Butterfly Valve Seat
Neoprene (CR)
Neoprene, Polychloroprene inoumbwa ne chloroprene monomer polymerization. Mushure mevulcanization, ine yakanaka rabha elasticity uye abrasion kuramba. Iye anti-insolation uye ine yakanaka yemamiriro ekunze kuramba, inoshingirira kunyonganiswa kwechisimba, mafiriji, dilute acid, silicon ester lubricant, asi isingarambiki kune phosphate series yehydraulic oil. Zviri nyore kupenya uye kuomesa pakudziya kwakadzika, kusasimba kwekuchengetedza, uye kuwedzera kukuru munzvimbo yakaderera aniline yemafuta emaminerari. Mukushandisa tembiricha range iri - 50 ~ 150 dhigirii.
Zvakanakira:
Yakanaka elasticity uye yakanaka compression deformation, iyo fomula haina sarufa, saka iri nyore kwazvo kushanda. Iyo ine anti - mhuka nemafuta emuriwo zvivakwa, haizokanganiswe neyakarerekera makemikari, mafuta, oiri, akasiyana mafuta, zvinonyungudutsa, uye zvakare ine anti - moto zvivakwa.
Zvakaipa:
Usakurudzira kushandisa mune yakasimba acids, nitrohydrocarbons, esters, chloroform uye ketone makemikari.
Application:
Zvikamu zverabha kana zvikamu zvekuisa chisimbiso neR12 refrigerant, midziyo yemumba. Inokodzera zvigadzirwa zverabha zvinonangana nemhepo, chiedza chezuva, ozone zvikamu, kuramba moto uye kemikari corrosion.
Chitupa:
KTW W270 EN681-1,ACS,NSF61/372;WRAS,EC1935;FDA,EC1935;REACH,ROHS
Zvatiri Zvakanakira:
1. Rubber uye framework zvinhu zvakasungwa zvakasimba.
2. Yakanakisa rubber elasticity uye compression set.
3. Yakagadzikana chigaro saizi uye diki torque, yakanakisa chisimbiso uye kupfeka kuramba pfuma.
4. Rubber zvinhu zvinotora mhando dzepasi rose nekuita kwakagadzikana.
5. Nyaya: CR, NR, SBR, NBR, EPDM, PTFE, Silicone, nezvimwewo.
6. Certification: NSF,SGS,KTW,FDA,ISO9001,ROHS,
7. High / low temperature resistance, mafuta nemafuta kuramba, good air tightness etc.
8. Maitiro uye kurongedza zvinoenderana nezvaunoda.
9. Kushandisa: Fluid control, zvemagetsi, midziyo yemumba, motokari, indasitiri yemidziyo yezvokurapa, muchina wemaindasitiri & zvikamu, nezvimwe.
