Qhov tsis zoo:

· Tsis haum rau polar solvents xws li ketones, ozone, nitro hydrocarbons, MEK thiab chloroform. · Siv los ua cov roj tank, lubricating roj tank thiab roj hmab qhov chaw, tshwj xeeb tshaj yog sealing qhov chaw, siv nyob rau hauv roj av hydraulic roj, roj av, dej, silicon roj, silicon roj, diester lubricating roj, ethylene glycol hydraulic roj thiab lwm yam dej xov xwm. Nws yog qhov siv ntau tshaj plaws thiab tus nqi qis tshaj roj hmab foob.

FKM

Fluoro Carbon Rubber Txhua yam nyob ntawm cov ntsiab lus fluorine (monomer qauv) ntawm fluorine molecules. Kev kub siab ua haujlwm zoo dua li cov roj hmab silicone, muaj cov tshuaj tiv thaiv zoo heev, tsis kam rau feem ntau ntawm cov roj thiab hnyav (tshwj tsis yog ketone, ester), huab cua tsis kam thiab ozone kuj; Kev ua haujlwm txias tsis zoo, kev siv dav dav ntawm qhov kub ntawm -20 ~ 250 ℃. Cov mis tshwj xeeb tuaj yeem tiv taus qhov kub thiab txias txog -40 ℃. Qhov zoo:

· Kub tiv taus rau 250 ℃

· Resistant rau feem ntau cov roj thiab cov kuab tshuaj, tshwj xeeb tshaj yog tag nrho cov acids, aliphatic, aromatic thiab tsiaj thiab zaub roj

Qhov tsis zoo:

· Tsis pom zoo rau ketones, esters ntawm qhov hnyav molecular thiab cov khoom sib xyaw uas muaj nitrate. · Tsheb, locomotives, diesel xyaw thiab roj systems.

SIL

Silicone Rubber lub ntsiab saw yog ua los ntawm silicon (-si-O-Si) sib koom ua ke. Cov cua kub zoo heev, ua haujlwm txias, tiv thaiv ozone, atmospheric aging kuj. Kev ua haujlwm zoo ntawm hluav taws xob rwb thaiv tsev. Lub zog tensile ntawm cov roj hmab zoo tib yam tsis zoo thiab tsis muaj roj tsis kam. Qhov zoo:

· Tensile zog mus txog 1500PSI thiab kua muag tsis kam mus txog 88LBS tom qab tsim

· Zoo elasticity thiab zoo compression distortion

· Zoo tiv thaiv rau nruab nrab cov kuab tshuaj

· Cov cua kub zoo heev

· Zoo heev tiv taus txias

· Zoo heev tiv thaiv ozone thiab oxide yaig

Kev ua tau zoo ntawm hluav taws xob rwb thaiv tsev

· Cov rwb thaiv tsev zoo heev thiab cua sov dissipation

Qhov tsis zoo:

· Tsis pom zoo siv rau hauv feem ntau cov kuab tshuaj concentrated, roj, concentrated acids thiab diluted sodium hydroxide. · Cov ntsaws ruaj ruaj lossis cov khoom siv roj hmab siv hauv kev lag luam hauv tsev, xws li hluav taws xob POTS, hlau, roj hmab qhov chaw hauv microwave ncu.

· Cov ntsaws ruaj ruaj lossis cov khoom siv roj hmab hauv kev lag luam hauv hluav taws xob, xws li cov xov tooj ntawm tes, cov khoom poob siab hauv DVD, cov ntsaws ruaj ruaj hauv cov hlua khi, thiab lwm yam.

· Seals ntawm txhua yam khoom nyob rau hauv kev sib cuag nrog tib neeg lub cev, xws li cov fwj dej, cov kwj dej, thiab lwm yam.

Epdm

Ethylene Roj Hmab (PPO) yog copolymerized los ntawm Ethylene thiab propylene rau hauv cov saw tseem ceeb thiab muaj cov cua sov zoo, kev laus tsis kam, ozone tsis kam thiab ruaj khov, tab sis tsis tuaj yeem ntxiv cov sulfur. Yuav kom daws tau qhov teeb meem no, ib qho me me ntawm cov khoom thib peb nrog ob txoj saw yog nkag mus rau hauv cov saw tseem ceeb ntawm EP, uas tuaj yeem tsim los ntawm kev ntxiv sulfur rau EPDM. Qhov dav dav qhov kub thiab txias yog -50 ~ 150 ℃. Kev tiv thaiv zoo heev rau cov kuab tshuaj polar xws li cawv, ketone, glycol thiab phosphate lipid hydraulic kua.

Qhov zoo:

· Huab cua tsis kam thiab ozone kuj

· Cov dej tsis kam zoo thiab tshuaj lom neeg

· Cawv thiab ketones tuaj yeem siv tau

· Kub kub tsis kam, zoo impermeability rau roj

Qhov tsis zoo:

· Tsis pom zoo rau kev siv zaub mov los yog raug rau cov ntxhiab hydrogen. · Cov ntsaws ruaj ruaj rau qhov kub siab dej vapor ib puag ncig.

· Cov ntsaws ruaj ruaj lossis cov khoom siv rau chav dej.

· Cov khoom siv roj hmab hauv lub braking (braking) system.

· Cov ntsaws ruaj ruaj hauv lub tshuab hluav taws xob (tsheb dej tank).
