1, Nitrile rubber
Solenoid valve ni hpe gaw, sau hte acrylonile hpe emulsion polymerization kaw na galaw ai rai nna, madung hku nna n-gun n law ai n-gun dat hpe n-gun dat dat ai lam hte hpawng de da ai. Shi gaw sau hpe ninghkap lu ai atsam grai kaja ai, n-gun ja ai hpe ninghkap lu ai, katsi ai hpe ninghkap lu ai hte n-gun ja ai n-gun ni nga ai. Shi a n kaja ai lam ni gaw n kaja ai nbung katsi ai hpe ninghkap lu ai, ozone n kaja ai, wan n-gun n kaja ai, n-gun n law ai elasticity ni rai nga ai.
Dai hta n-ga, hka hpe ninghkap lu ai atsam kaja ai, nbung n-gun hte n-gun kaja ai lam ni hpe mung lu la ai. Dai hpe sau n-gun n-rawng ai rubber arung arai amyu myu hpe galaw shapraw ai, sau n-gun n-rawng ai wan sau, gasket, n-gup n-gu, n-gun n-gun n-rawng ai, n-gun rawng ai, hose, laika ka ai hte nsam ni hpe ka shapraw ai, cable rubber arung arai ni, etc. ni hpe galaw shapraw ai hta grai lang ai rai nna, mawdaw, nbungli, wan sau, copy galaw ai, copy galaw ai, electronic hte kaga hpaga lam ni hta ahkyak ai elastic arung arai langai byin wa sai. Kaga hpaga lam ni.
Nitrile rubber (NBR) gaw sau hpe grai hkam sharang lu ai, lahkawng ngu na hta gaw polysulfide rubber hte fluorubber hpe n-gun n-gun hte nbung n-gun hpe hkam sharang lu ai. NBR a n kaja ai lam gaw, ozone hte aromatic, halogenated hydrocarbon, ketone hte estern solvents ni hpe n hkam sharang lu ai majaw, n-gun n rawng ai arung arai ni a matu n htap htuk ai.
Madung lang ai lam ni: NBR hpe madung hku nna sau hpe n hkap la lu ai pipe, tape, rubber diaphragm, sau htinggaw kaba ni hte kaga sau n-gun n-gun ni hpe galaw shapraw na matu lang ai, ga shadawn, O{0}}ring, sau n-gun, gawm, diaphragm, diaphragm, valve, bellows, etc. ni hpe galaw shapraw ai.
2, EPDM rubber
EPDM gaw ethylene, propylene hte n-htuk n-htuk ai hku sha ai terpolymer langai mi re. 1963 ning hta hpaga lam galaw ai rai nna, mungkan gaw laning mi hta ton 800000 hpe jai lang ai. EPDM a madung arawn alai ni gaw grai kaja ai oxidation hpe ninghkap lu ai atsam, ozone hpe ninghkap lu ai hte n-gun n-gun hpe ninghkap lu ai atsam ni rai nga ai. EPM gaw polyolefin hta lawm nna, grai kaja ai vulcanization galaw ai lam nga ai. Ethylene propylene diene monomer (EPPDM) gaw rubber yawng hta n law dik htum nga ai. Dai gaw filler hte sau law law hpe hkap la lu ai, shi a bungli galaw ai lam hpe mung loi mi sha n-gun n jaw lu ai. Dai majaw, manu n law ai rubber compound ni hpe galaw shapraw lu ai.
Molecular hkrang hte atsam marai ni
Structure: ethylene propylene terpolymer ngu ai gaw ethylene, propylene hte n-hkap la ai sha lu sha ai lam a terpolymer langai mi re. Dinenes ni hta laksan structure ni nga ai. Dai bond lahkawng kaw na langai sha copolymerized galaw mai ai. N-gun n rawng ai double bond hpe madung hku nna crosslinking agent hku nna lang ai. Kaga n-gun n rawng ai polymer langai gaw main chain n re, side chain langai mi re. EPDM a madung lam gaw tsep kawp n-gun n rawng ai. Ndai atsam gaw EPDM katsi ai hpe n-gun n-gun n-nga ai, n-gun n-rawng ai, oxygen hpe n-gun n-rawng ai, grau nna ozone hpe n-gun n-rawng ai hku galaw ya ai. Ethylene propylene terpolymer gaw madung hku nna nonpolar, polar hka hte tsi mawan ni hpe ninghkap lu ai, hka n law ai hte n-gun n rawng ai lam kaja ai.
Features: 1. wan n-gun; 2. elasticity; 3. n-gun ja ai; 4. n-gun n law ai hte hpring tsup ai; 5. superheater hpe ninghkap lu ai; 6. hka n-gun hpe ninghkap lu ai; 7. anti-aging arung arai; 8. corrosion hpe ninghkap lu ai.
3, Fluororubber (FKM)
Molecules ni hta n bung ai fluorine n-gun, ngu ai monomer structure ngu ai n bung ai flubers ni nga ai. Ya aten hta, n-gun rawng ai lam hpe n-gun jaw ai lam gaw, DuPont hpe "fluorubber" ngu ai mying hte shawng ningnan lang ka da ai. Silicone rubber hta nbung katsi ai hpe ninghkap lu ai atsam grau kaja ai. Shi gaw kaja ai chemical hpe ninghkap lu ai, sau hte hka htung law malawng hpe ninghkap lu ai atsam nga ai (ketones hte esters ni hta lai nna), nbung laru kaja ai hte ozone hpe ninghkap lu ai, raitim, katsi ai hpe ninghkap lu ai n kaja ai; shi hpe mawdaw, B hte kaga arung arai ni hta law law lang lang ai, chemical plant ni hta seal ni hpe lang nna,- 20℃kaw nna 260℃du hkra, daw jau ai lam a n-gun gaw . N-gun n law ai nbung hpe n-gun n-ja ai hku galai shai ai shaloi,- 40℃de bang mai ai raitim manu gaw n kaja ai. Grau ai.
