O le NBR o loʻo i ai le suauʻu lelei, EPDM e le lelei i le suauʻu ma e le umi, ae mafai ona tetee atu i le matua ma le vevela.E masani lava, EPDM e masani ona faʻaaogaina mo paipa vai ma luga o le ausa;E sili atu le lelei o le EPDM i le fa'afefe.
1. Nitrile pa'u NBR o se polar unsaturated carbon filifili pa'u, lea e copolymerized mai acrylonitrile ma butadiene.Faʻalagolago i mea o loʻo i totonu o le acrylonitrile mai le maualalo i le maualuga, o loʻo faʻaleleia le suauʻu, ae faʻaitiitia le malulu.
O le suau'u tete'e o le vaega pito sili lea o le NBR nitrile pa'u, lea e lelei le tete'e atu i suau'u fa'avae suau'u ma non-polar solvents, ae le lelei le tetee atu i suauu polar ma polar solvents.
1. Lelei antistatic meatotino;
2. Le lelei osone tetee;
3. E lelei le fetaui lelei ma mea polar, e pei o le polyvinyl chloride (PVC), polyoxymethylene (POM), nylon, ma e mafai ona faia i mea paʻu ma palasitika.
4. O le faʻaogaina o le vevela o le paʻu nitrile masani: -20 ° C ~ 120 ° C, ma le maualalo o le vevela o ituaiga e mafai ona maualalo ifo i le -50 ° C;
2. Ethylene-propylene pa'u fa'aaogaina le ethylene ma le propylene e fai ma mea fa'apipi'i, ma e mafai ona vaevaeina i le binary ethylene-propylene rubber (EPM) ma le tertiary ethylene-propylene rubber (EPDM).
Tulaga o le ethylene propylene rubber:
1. Osone matua tetee
2. Tete'e tau
3. Tete'e vevela
O meatotino e tolu o loʻo i luga e sili ona lelei ile paʻu lautele.O lo'o iai fo'i meatotino nei
4. Vaitafe sili ona lelei, teteʻe o le vevela ma le vai ausa;
5. sili ona tetee kemikolo;
(Ona o le mautu o vailaʻau ma le le polarity o le ethylene-propylene paʻu lava ia, e le faʻafefeteina ma le tele o vailaʻau, e le fetaui pe itiiti le fetaui ma mea polar, ma e tetee i le ava malosi, acid, malosi alkali, oxidizing. vailaʻau, vailaʻau fufulu, suauʻu manu ma fualaau faisua, ketones, ma isi.)
O le NBR e malu, EPDM e sili atu ona faigata ma e ese lona tofo
1. Fa'ailoga lautele o le pa'u
(1) Pa'u lautele: pei ole NR/BR/SBR/EPDM
(2) Pa'u fa'apitoa: pei ole SR/FPM/CIIR/HNBR/CSM 2.
Nitrile pa'u NBR e lelei le suau'u tete'e, e masani ona ta'ua o le suauu-fa'amaonia pa'u, ma e masani ona faʻaaogaina e fai ma faʻamaufaʻailoga suauu.
NR pa'u natura lelei elasticity ma lelei atoatoa faatinoga, ae le lelei le malulu tetee ma alkali tetee.E masani ona fa'aaogaina e fai ma pa'u ta'avale
Styrene Butadiene Rubber SBR O le pa'u sili ona taugofie i le lalolagi, fa'aaoga e fai ma papa
O le EPDM o loʻo i ai le lelei o le faʻafefeteina ma le faʻamalama lelei, ma e mafai ona faʻaaogaina e fai ma mea e faʻafefeteina poʻo mea eletise eletise maualuga.
Neoprene CR e lelei le ofuina o lavalava ma e mafai ona faʻaaogaina e fai ma aluga Chlorosulfonated polyethylene CSM e lelei le malulu.
Polytetrafluoroethylene PTFE
Tupu palasitika, sili atu acid ma alkali tetee, e mafai ona tetee hydrofluoric acid.O lo'o i ai le tele o fa'aoga ma e mafai ona fa'aaogaina e fai ma paipa mo vai fa'a'a'ala.
Hebei CONQI VEHICLE FITTINGS Co., Ltd. o se kamupani tuuto e gaosia ma tufatufa atu o le pa'u pa'u ta'avale, fa'aga EPDM, fa'agasolo mea'ai ma fa'agaau pvc ma isi fa'atasi ai ma le poto masani o le gaosiga, fa'atekonolosi gaosiga maualuga ma se fa'atonuga lelei atoatoa ma fa'asaienisi.I le 2009, na faʻamaeʻaina e le kamupani le aofaʻi o galuega faʻapisinisi e 10.01 miliona yuan ma faʻamaeʻaina se lafoga faleteuoloa o 250,000 yuan.O i latou uma e fetaui ma le sili atu ma le 30 OEM i totonu o le atunuʻu e pei o Jinlong, Yutong, Ankai, ma Zhongtong, ma faʻatasi ai ma lala faavaomalo o Volvo ma Initia, Niu Sila, Taialani, Taiuani, Polani, Isaraelu, Peretania, Aikupito, Sepania, Turkey, Pasila, Sigapoa, Siamani ma sili atu nai lo le 20 atunuu ma itulagi ua maua nofoaga lagolago.O le pipii atu i le mataupu o le "faʻaauau pea le faʻaleleia, lelei, sili ona lelei, ma le faʻamalieina o tagata faʻatau", matou te puʻeina faʻamatalaga faʻavaomalo faʻavaomalo ma faʻamatalaga oloa, faʻataʻitaʻiina ma atinaʻe oloa fou, ma tuʻuina atu tagata faʻatau.
