Anti-manu ma fuala'au suau'u talafeagaiNeoprene (CR) Butterfly Valve Nofo
Neoprene (CR)
Neoprene, Polychloroprene e aofia ai le chloroprene monomer polymerization. Ina ua uma vulcanization, e lelei elasticity pa'u ma abrasion tetee. E tetee-insolation ma e lelei le teteʻe o le tau, tetee atu i le vevesi faʻalavelave, refrigerants, dilute acid, silicon ester lubricant, ae le tetee i le phosphate faasologa o suauu hydraulic. E faigofie ona faʻamaʻa ma faʻamaʻaʻaina i le maualalo o le vevela, vaivai le teuina o le mautu, ma le faʻalauteleina tele i le maualalo o le aniline o le suauu minerale. I le faʻaaogaina o le vevela o le - 50 ~ 150 tikeri.
Tulaga lelei:
Elasticity lelei ma lelei compression deformation, o le fua faatatau e leai se sulfur, o lea e matua faigofie ona faagaoioia. O lo'o i ai mea fa'aanti-manu ma fuala'au suau'u, o le a le a'afia i vaila'au fa'aituau, ga'o, suau'u, suau'u eseese, solvents, ma e iai fo'i mea fa'aanti- afi.
Fa'aletonu:
Aua le fautuaina e faʻaaoga i vailaʻau malosi, nitrohydrocarbons, esters, chloroform ma ketone ketone.
Talosaga:
Vaega pa'u po'o vaega fa'amaufa'ailoga fa'atasi ma le fa'aaisa R12, mea faigaluega a le fale. E talafeagai mo oloa pa'u e feso'ota'i sa'o ma le ea, susulu o le la, vaega o le osone, tetee atu i le afi ma le pala.
Tusi Faamaonia:

5. Mea: CR, NR, SBR, NBR, EPDM, PTFE, Silicone, ma isi.
6. Faʻamaonia: NSF,SGS,KTW,FDA,ROHS,
7. maualuga / maualalo le vevela tetee, suauu ma suauu tetee, lelei ea tightness ma isi.
8. Faʻagasologa ma faʻapipiʻiina e tusa ai ma ou manaʻoga.
9. Fa'aoga: Pulea o le vai, eletise, mea faigaluega a le fale, ta'avale, falema'i meafaigaluega, masini fale gaosimea & vaega, ma isi.
Mea Fa'afeso'ota'i Laupapa Filifiliga Vave:
| Mea | Talafeagai Temp. | Uiga |
| NBR |
-35℃~100℃ Vave -40℃~125℃ |
O le pa'u nitrile e lelei lona lava - fa'alauteleina meatotino, abrasion tete'e ma hydrocarbon - mea e tete'e. E mafai ona faʻaaogaina e avea o se mea lautele mo vai, vacuum, acid, masima, alkali, gaʻo, suauu, pata, suauʻu hydraulic, glycol, ma isi. E le mafai ona faʻaaogaina i nofoaga e pei o le acetone, ketone, nitrate, ma fluorinated hydrocarbons. |
| EPDM |
-40℃~135℃ Vave -50℃~150℃ |
Ethylene-propylene pa'u ose lelei lautele-fa'amoemoega pa'u gaosia e mafai ona fa'aogaina i vai vevela, meainu, mea susu, ketones, ava malosi, nitrates, ma glycerin, ae le o totonu o le hydrocarbon-su'u fa'avae, inorganics, po'o solvents.

Fausia mai se fa'afefiloi malosi o mea pa'u natura ma fa'alanuina i se fa'ai'uga uliuli fa'apolofesa, o lenei nofoa valve butterfly e fa'amautinoa e le mafaatusalia le tumau ma le fa'atinoga. O lona tu'ufa'atasiga fa'apitoa e mafai ai ona tatalia le vevela e amata mai i le -50 i le 150 tikeri Celsius, ma avea ai ma filifiliga lelei mo le tele o fa'aoga, mai vai inu ma vai inu i le puleaina o le suavai leaga. O le maufetuunaʻi o le PTFE tuʻufaʻatasia ma le fetuutuunaʻi o le EPDM e fatuina ai se fofo faʻamaufaʻailoga e le gata ina umi ae faʻapitoa foi i ituaiga faʻasalalauga eseese.O le Elastic Butterfly Valve Seat e sili atu nai lo na o se vaega; ose vaifofo ua fuafuaina e fa'aopoopoina ai le fa'atinoga ole bray fa'amaufa'ato'a nofo fa'alava pepe. O lona fetaui lelei ma le vai, vai inu, vai inu, ma le suavai leaga o loʻo faʻamaonia ai lona faʻaogaina, ma avea ai o se filifiliga le faʻamaonia mo faiga e manaʻomia ai le pulea lelei o le tafe. O le tu'ufa'atasiga lelei o lenei nofoa valve i totonu o au masini e fa'amautinoa ai le fa'aleleia atili o le fa'agaioiga, fa'aitiitia le tau o le tausiga, ma le fa'aumiumi o le soifua tautua, ma maua ai se tupe maua tele i tupe fa'afaigaluega. Pe faʻaleleia se faiga o loʻo i ai nei poʻo le faʻatinoina o mea fou, o le Suia Resilient PTFE + EPDM Butterfly Valve Seat e le Sansheng Fluorine Plastics e ofoina atu le faʻatinoina ma le faʻamaoni, e faʻaalia ai le uiga o le maualuga -
