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 teteʻeina o le tau, tetee atu i le vevesi faʻalavelave, refrigerants, dilute acid, silicon ester lubricant, ae le faʻasaʻo i 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 fa'afeso'ota'i sa'o ma le ea, susulu o le la, vaega o le ozone, tetee atu i le afi ma le pala.
Tusi Faamaonia:
KTW W270 EN681-1,ACS,NSF61/372;WRAS,EC1935;FDA,EC1935;REACH,ROHS
O matou Fa'amanuiaga:
1. O pa'u ma mea fa'ava'a o lo'o pipii mau.
2. Elasticity paʻu sili ona lelei ma seti faʻapipiʻi.
3. Tele nofoa mautu ma torque laʻititi, faʻamaufaʻailoga sili ona lelei ma le ofuina o mea e tetee ai.
4. Fa'aaoga mea pa'u fa'ailoga fa'ava-o-malo ma fa'atinoga mautu.
5. Mea: CR, NR, SBR, NBR, EPDM, PTFE, Silicone, ma isi.
6. Faʻamaonia: NSF,SGS,KTW,FDA,ISO9001,ROHS,
7. maualuga / maualalo 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-faamoemoega pa'u gaosia e mafai ona fa'aoga i vai vevela, meainu, oloa susu, ketones, ava malosi, nitrates, ma glycerin, ae le o le hydrocarbon-suau'u fa'avae, inorganics, po'o solvents.
|
| CR |
-35℃~100℃ Vave -40℃~125℃ |
Neoprene e faʻaaogaina i ala o faasalalauga e pei o acids, suauʻu, gaʻo, pata ma solvents ma e lelei le tetee i osofaʻiga. |
| FKM |
-20℃~180℃

O le Fluororubber o se suau'u fa'ameamea lelei-fa'asa'o, pa'u fa'apalapala fa'afefete mo le ga'o ga'o ma isi mea tau suau'u. E talafeagai mo le vai, suauu, ea, acid ma isi ala o faasalalauga, ae e le mafai ona faaaogaina mo le ausa, vai vevela pe mafiafia nai lo 82 °C. Alkali faiga. |
| SR | -70℃~200℃ | Silicone pa'u e tetee atu i le maualuga o le vevela, maualalo le vevela ma mea tau kemisi mautu, ma e masani ona faʻaaogaina i pisinisi e pei ole malosi malosi, vaivai alkali ma meaʻai. |
Mea fa'apitoa: pa'u nitrile carboxylated, pa'u nitrile hydrogenated, pala-ethylene tete'e-pa'u propylene, ausa-fluoroelastomer tetee, polyethylene chlorosulfonated |

Fausia ma le toto'a mai se tu'ufa'atasiga o le PTFE ma le EPDM, o nei nofoa valve ua mamanuina e tatalia le faigata o le vevela tele, mai le -50 i le 150 tikeri Celsius. O lenei fa'apalepale mata'ina o le vevela e talafeagai ai mo le lautele o alaleo o ala o faasalalauga, e aofia ai le vai, vai inu, vai inu, ma e o'o lava i siosiomaga vai leaga. O le lanu uliuli, mea pa'u natura e le gata ina ofoina atu le elasticity maualuga ae e folafola atu ai foi le umi ma le maufetuuna'i e tetee atu i le ofuina ma loimata, faʻamautinoaina o lau valve butterfly o loʻo galue sologa lelei i taimi uumi. mea e mafai ona suia, e mafai ai ona faigofie le tausiga ma faʻalauteleina le ola tautua o le valve lava ia. O lenei uiga e sili ona aoga i totonu o fale gaosi oloa e mafai ona i ai se aafiaga taua i le gaosiga ma le manuia. Pe mo vai vai, HVAC system, po'o fa'ato'aga fa'ato'aga, o nei nofoa valve e ofoina atu se fa'afefiloi e le mafaatusalia o le fa'atinoga, tumau, ma le aoga. Faatasi ai ma le Sansheng Fluorine Plastics, ia mautinoa o loʻo e filifili mo se fofo e le gata i le taʻimua o mea faʻatekonolosi faʻafouina ae o loʻo lagolagoina foi e le lagolago atoatoa ma le tomai i le matata o le fluorine plastics.
