Anti-zinyama ndi masamba mafuta oyeneraNeoprene (CR) Gulugufe Valve Mpando
Neoprene (cr)
Neoprene, Polychloroprene amapangidwa ndi chloroprene monomer polymerization. Pambuyo poti chipongwe, chimakhala ndi kuthekera bwino kwa mphira komanso kukana kwa abrasi. Ndi Anti -kusangalatsa Ndipo khalani ndi vuto la nyengo, chotsani zosokoneza mwankhanza, kutsuka acid acid, sicricn ester, koma osalimbana ndi Mafuta a Hydraulic. Ndikosavuta kulira ndi kuumitsa kutentha kochepa, kukhazikika kokhazikika, komanso kukulitsa kwakukulu kwa aniline pointral mafuta. Pogwiritsa ntchito mtengo wa kutentha ndi - 50 ~ 150 digiri.
Ubwino:
Kuwonongeka kwabwino ndi kusinthana kwabwino, mawonekedwewo alibe sulufule, motero ndizosavuta kugwira ntchito. Ili ndi anti - Mafuta a nyama ndi masamba, sizikhudzidwa ndi mankhwala osalowerera, mafuta, mafuta, mafuta osiyanasiyana, ma sol sol, komanso anti.
Zoyipa:
Osalimbikitsa kugwiritsa ntchito mu ma acid olimba, nitrohydcarborsbonsbons, esters, chloroform ndi ketone mankhwala.
Ntchito:
Ziwalo za mphira kapena zigawo zikopa ndi R12 Firiririge, zida zapanyumba. Oyenera kupanga zinthu za mphira zomwe kulumikizana mwachindunji ndi mlengalenga, dzuwa, zigawo za ozoni, pewani moto ndi kuwononga mankhwala.
Chiphaso:
KTW W270 EN681-1,ACS,NSF61/372;WRAS,EC1935;FDA,EC1935;REACH,ROHS
Ubwino Wathu:
1. Rubber ndi chimango zakuthupi zimamangirizidwa mwamphamvu.
2. Wabwino mphira elasticity ndi psinjika anapereka.
3. Kukula kwa mpando wokhazikika ndi torque yaying'ono, kusindikiza bwino komanso kuvala katundu wotsutsa.
4. Zida za mphira zimatengera mitundu yapadziko lonse lapansi yokhala ndi magwiridwe antchito okhazikika.
5. Zida: CR, NR, SBR, NBR, EPDM, PTFE, Silicone, etc.
6. Chitsimikizo: NSF, SGS,KTW,FDA,ROHS,
7. Kutentha kwakukulu / kutsika kwa kutentha, kukana kwa mafuta ndi mafuta, kutsekemera kwa mpweya wabwino etc.
8. Njira ndi kulongedza zimagwirizana ndi zomwe mukufuna.
9. Ntchito: Kuwongolera kwamadzi, zamagetsi, zida zapakhomo, magalimoto, zida zamankhwala makampani, makina ogulitsa & zigawo, etc.
Zogwirizana Mwachangu Zosankha:
| Zakuthupi | Temp Yoyenera. | Makhalidwe |
| NBR |
- 35 ℃ ~ 100 ℃ Instant -40 ℃~125 ℃ |
Rabara ya nitrile ili ndi zabwino zokha-yokulitsa katundu, kukana abrasion ndi hydrocarbon-yosamva. Itha kugwiritsidwa ntchito ngati zinthu zambiri zamadzi, vacuum, asidi, mchere, alkali, mafuta, mafuta, batala, mafuta a hydraulic, glycol, etc. Sangagwiritsidwe ntchito m'malo monga acetone, ketone, nitrate, ndi fluorinated hydrocarbons. |
| Chithunzi cha EPDM |
- 40 ℃ ~ 135 ℃ Instant - 50 ℃ ~ 150 ℃ |
Ethylene-propylene rabara ndi wabwino general-cholinga kupanga labala kuti angagwiritsidwe ntchito m'makina madzi otentha, zakumwa, mkaka, ketoni, alcohols, nitrates, ndi glycerin, koma osati mu hydrocarbon-ochokera mafuta, inorganics, kapena solvents.

- 35 ℃ ~ 100 ℃ Instant -40 ℃~125 ℃ |
Neoprene imagwiritsidwa ntchito pazofalitsa monga zidulo, mafuta, mafuta, ma butters ndi zosungunulira ndipo zimakhala bwino kukana kuukira. |
| Mtengo wa FKM |
- 20 ℃ ~ 180 ℃

Fluorororor ndi hydrocarbon - mafuta oletsa, fluorinated hydrocarbon rabara yamafuta a mafuta ndi zinthu zina. Ndioyenera madzi, mafuta, mpweya, acid ndi ena media, koma sizingagwiritsidwe ntchito pa nthunzi, madzi otentha kapena kukula kuposa 82 ° C. Dongosolo la alkali. |
| SR | - 70 ℃ ~ 200 ℃ | Rabara ya silicone imagonjetsedwa ndi kutentha kwakukulu, kutentha kochepa komanso kukhazikika kwa mankhwala, ndipo imagwiritsidwa ntchito kwambiri m'mafakitale monga asidi amphamvu, alkali ofooka ndi chakudya. |
Zida zapadera: rabara ya nitrile ya carboxylated, rabala ya nitrile ya hydrogenated, dzimbiri-resistant ethylene-propylene rabara, nthunzi- zosagwira fluoroelastomer, chlorosulfonated polyethylene |
