Daim ntawv thov			Tsawg Mooney viscosity, zoo heev processability, haum rau ua extruded khoom xws li roj hmab hoses thiab rollers			Fluorine roj hmab saib pluaj: Cim mos kov, xis nyob heev - Kov - Tsis-nplaum, du, hnav-tiv taus thiab ruaj khov, hws-resistant, tiv thaiv kev ua qias tuaj, dej-resistant thiab roj-resistant, tsis yooj yim rau discolor			Lub zog tensile siab, me me compression mus tas li deformation, tiv taus dej vapor, muaj zog acids, alkalis, thiab muaj zog oxidants, thiab lwm yam.

 

 

► Nws yog tsim rau molding o-rings, gaskets, ntau yam uas tsis yog-bonding sealing qhov chaw.

► Nws tuaj yeem siv rau kev hloov pauv molding, compression molding thiab txhaj tshuaj molding.

 

 

► 25 kg ib lub thawv
► 500 kg ib pallet
 

 

 

► 6-12 lub hlis raws li kev pom zoo cia.

 

 

► Corrosion kuj
Fluororubber muaj kev tiv thaiv corrosion zoo heev. Feem ntau hais lus, nws yog qhov zoo dua li lwm cov roj hmab hauv cov ntsiab lus ntawm kev ruaj ntseg tiv thaiv cov organic kua (roj roj, cov kuab tshuaj, cov xov xwm hydraulic, thiab lwm yam), cov concentrated acids (nitric acid, sulfuric acid, hydrochloric acid), high concentrations hydrogen peroxide thiab lwm yam muaj zog. oxidants.

 

► o tsis kam
FKM roj hmab muaj qib siab ntawm tshuaj lom neeg ruaj khov thiab yog qhov nruab nrab zoo tshaj plaws ntawm txhua tus elastomers. Hom 26 fluororubber yog resistant rau roj av, roj diester, silicone ether roj, silica roj, inorganic acids, feem ntau cov organic thiab inorganic kuab tshuaj, thiab tshuaj. Nws tsuas yog tsis tiv taus qhov hnyav molecular ketones, ethers, esters, amines, ammonia, hydrofluoric acid, chlorosulfonic acid, thiab phosphoric acid hydraulic roj. Qhov nruab nrab kev ua tau zoo ntawm hom 23 fluororubber zoo ib yam li hom 26, thiab nws txawv dua. Nws yog qhov zoo dua li hom 26 hauv kev tiv thaiv kom muaj zog oxidizing inorganic acids xws li fuming nitric acid thiab concentrated sulfuric acid. Nws qhov ntim nthuav dav tom qab immersion hauv 98% HNO3 rau 27 hnub ntawm chav tsev kub tsuas yog 13% mus rau 15%.
 

► Kub thiab kub tsis kam
Nyob rau hauv cov nqe lus ntawm kev laus kuj, fluororubber yog piv rau silicone roj hmab thiab superior rau lwm yam roj hmab. Hom 26 fluororubber tuaj yeem ua haujlwm ntev ntawm 250 degree thiab luv luv ntawm 300 degree. Hom 23 fluororubber tseem muaj lub zog siab tom qab kev laus ntawm 200 degree × 1 000 h, thiab tuaj yeem tiv taus lub sijhawm luv luv ntawm qhov kub ntawm 250 degree. Lub thermal decomposition kub ntawm tetrapropylene fluororubber yog siab dua 400 degree, thiab nws tuaj yeem ua haujlwm ntev ntawm 230 degree. Kev hloov pauv ntawm fluororubber ntawm qhov kub sib txawv yog ntau dua li ntawm silicone roj hmab thiab cov roj hmab butyl. Nws lub zog tensile thiab hardness ob leeg txo qis nrog nce kub. Cov yam ntxwv hloov pauv ntawm lub zog tensile yog: qis dua 150 degree, nws txo qis nrog qhov kub thiab txias, thiab nruab nrab ntawm 150 thiab 260 degree, nws txo qis nrog qhov kub thiab txias.
 

► Compression teeb ua haujlwm
Compression set yog qhov tseem ceeb ntawm kev ua haujlwm ntawm fluororubber siv hauv kev sib khi ntawm qhov kub thiab txias. Lub compression teeb ua haujlwm ntawm hom 26 fluororubber zoo dua li ntawm lwm cov fluororubbers. Nws compression mus tas li deformation loj heev nyob rau hauv qhov kub thiab txias ntawm 200-300 degree .

 

► Huab cua thiab ozone tsis kam
FKM cov ntaub ntawv muaj huab cua zoo heev thiab ozone tsis kam. Hom 23 fluororubber kuj muaj huab cua zoo heev thiab ozone tsis kam.

 

► Mechanical Properties
Fluororubber feem ntau muaj lub zog tensile siab thiab hardness, tab sis tsis zoo elasticity. Hom 26 fluororubber feem ntau muaj lub zog ntawm 10 thiab 20 MPa, lub kua muag elongation ntawm 150 thiab 350%, thiab lub zog tsim kua muag ntawm 3 thiab 4 kN / m. Hom 23 fluororubber muaj lub zog ntawm 15.0 thiab 25 MPa, elongation ntawm 200% thiab 600%, thiab lub zog tsim kua muag ntawm 2 thiab 7 MPa. Feem ntau, fluororubber muaj qhov loj compression mus tas li deformation ntawm qhov kub thiab txias.

 

► Cov khoom siv hluav taws xob
Cov hluav taws xob rwb thaiv tsev kev ua tau zoo ntawm fluororubber tsis zoo heev thiab tsuas yog tsim nyog rau kev siv nyob rau hauv qis zaus thiab qis voltage. Qhov kub thiab txias muaj qhov cuam tshuam zoo rau nws cov khoom hluav taws xob. Thaum qhov kub nce ntawm 24 degree mus rau 184 degree, nws cov rwb thaiv tsev tsis kam txo los ntawm 35, 000 zaug. Hom thiab tus nqi ntawm cov fillers muaj kev cuam tshuam zoo rau cov khoom siv hluav taws xob. Precipitated calcium carbonate muab vulcanized roj hmab ntau dua cov khoom siv hluav taws xob, thaum lwm cov fillers yog me ntsis zuj zus. Raws li tus nqi ntawm cov fillers nce, cov khoom hluav taws xob txo qis raws li.
