I-Anti-amafutha ezilwane nawemifino afanele i-Neoprene (CR) I-Butterfly Valve Seat
I-Neoprene (CR)
I-Neoprene, i-Polychloroprene yenziwe nge-chloroprene monomer polymerization. Ngemuva kwe-vulcanization, inokunwebeka okuhle kwerabha kanye nokumelana nokuhuzuka. I-anti -ukuqabuleka futhi inokumelana nesimo sezulu esihle, imelana nokuhlanekezelwa okunobudlova, iziqandisi, i-asidi ehlanjululwe, i-silicon ester lubricant, kodwa ayimelani nochungechunge lwe-phosphate lwamafutha we-hydraulic. Kulula ukucwebezela futhi kube lukhuni ezingeni lokushisa eliphansi, ukuqina kwesitoreji okubuthakathaka, nokwanda okukhulu endaweni ephansi ye-aniline yamafutha amaminerali. Uma usebenzisa izinga lokushisa ngu- - 50 ~ 150 degrees.
Izinzuzo:
I-elasticity enhle kanye ne-compression deformation enhle, ifomula ayinaso isibabule, ngakho-ke kulula kakhulu ukusebenza. Inezici zokulwa - amafutha ezilwane kanye nemifino, ngeke ithintwe amakhemikhali angathathi hlangothi, amafutha, amafutha, izinhlobonhlobo zamafutha, izincibilikisi, futhi inezici zokunqanda umlilo.
Ububi:
Ungancomi ukuthi kusetshenziswe kuma-acids aqinile, ama-nitrohydrocarbon, ama-ester, i-chloroform namakhemikhali eketone.
Isicelo:
Izingxenye zenjoloba noma izingxenye zokuvala ngesiqandisi sika-R12, izinto zasendlini. Ifanele imikhiqizo yenjoloba ethintana ngqo nomkhathi, ukukhanya kwelanga, izingxenye ze-ozone, ukumelana nomlilo nokugqwala kwamakhemikhali.
Isitifiketi:
KTW W270 EN681-1,ACS,NSF61/372;WRAS,EC1935;FDA,EC1935;REACH,ROHS
Izinzuzo Zethu:
1. I-Rubber kanye nezinto zohlaka ziboshwe ngokuqinile.
2. I-elasticity yerabha enhle kakhulu kanye nesethi yokucindezela.
3. Usayizi wesihlalo ozinzile kanye ne-torque encane, ukubekwa uphawu okuhle kakhulu kanye nempahla yokumelana nokugqoka.
4. Izinto zenjoloba zamukela imikhiqizo yamazwe ngamazwe ngokusebenza okuzinzile.
5. Impahla: CR, NR, SBR, NBR, EPDM, PTFE, Silicone, njll.
6. Isitifiketi: NSF,SGS,KTW,FDA,ROHS,
7. Ukumelana nokushisa okuphezulu / okuphansi, ukumelana nowoyela nophethiloli, ukuqina komoya okuhle njll.
8. Inqubo nokupakisha kuhambisana nezidingo zakho.
9. Isicelo: Ukulawula uketshezi, ugesi, izinto zikagesi zasendlini, ezezimoto, imboni yemishini yezokwelapha, umshini wezimboni nezinto ezisetshenziswayo, njll.
Ithebula Lokukhetha Okusheshayo Lezinto Ezihlobene:
| Okubalulekile | I-Temp Efanelekayo. | Izici |
| I-NBR |
- 35℃~100℃ Okusheshayo -40℃~125℃ |
Irabha ye-nitrile inezakhiwo ezinhle ezizikhulisayo, ukumelana nokuhuzuka kanye ne-hydrocarbon-ukumelana nezindawo. Ingasetshenziswa njengezinto ezijwayelekile zamanzi, i-vacuum, i-asidi, usawoti, i-alkali, amafutha, uwoyela, ibhotela, uwoyela we-hydraulic, i-glycol, njll. Ayikwazi ukusetshenziswa ezindaweni ezifana ne-acetone, i-ketone, i-nitrate, nama-hydrocarbon ane-fluorinated. |
| I-EPDM |
-40℃~135℃ Okusheshayo -50℃~150℃ |
Irabha ye-ethylene-propylene ijwayelekile-injoloba yokwenziwa ehloselwe engasetshenziswa ezinhlelweni zamanzi ashisayo, iziphuzo, imikhiqizo yobisi, ama-ketone, utshwala, i-nitrate, ne-glycerin, kodwa hhayi ku-hydrocarbon-amafutha asekelwe ku-hydrocarbon, izinto ezingaphili, noma izinyibilikisi.

| CR |
- 35℃~100℃ Okusheshayo -40℃~125℃ |
I-Neoprene isetshenziswa emithonjeni yezindaba efana nama-asidi, amafutha, amafutha, amabhotela nezinyibilikisi futhi inokumelana okuhle nokuhlasela. |
| I-FKM |
-20℃~180℃

I-Fluororubber iyi-hydrocarbon-uwoyela wesisekelo omuhle ongazweli, irabha ene-fluorinated hydrocarbon yegesi enamafutha neminye imikhiqizo ye-petroleum. Ilungele amanzi, uwoyela, umoya, i-asidi nezinye imidiya, kodwa ayikwazi ukusetshenziselwa isitimu, amanzi ashisayo noma ugqinsi kuno-82 °C. Isistimu ye-alkali. |
| SR | - 70℃~200℃ | Irabha ye-Silicone imelana nokushisa okuphezulu, izinga lokushisa eliphansi kanye nezakhiwo zamakhemikhali ezizinzile, futhi isetshenziswa kabanzi ezimbonini ezifana ne-asidi eqinile, i-alkali ebuthakathaka nokudla. |
Izinto ezikhethekile: irabha ye-nitrile ene-carboxylated, irabha ye-nitrile ene-hydrogenated, ukugqwala-i-ethylene engazweli-irabha yepropylene, umusi-i-fluoroelastomer engazweli, i-chlorosulfonated polyethylene |
