Ihe ahaziri ahazi NBR/EPDM/FKM/SIL Rubber O-Ring

NBR

A na-akwado Nitrile Rubber site na copolymerization nke acrylonitrile na butadiene. Ọdịnaya nke acrylonitrile sitere na 18% ruo 50%. Ọdịnaya dị elu nke acrylonitrile, nke ka mma na-eguzogide mmanụ mmanụ hydrocarbon, mana arụmọrụ dị ala dị ala ka njọ, oke okpomọkụ eji eme ihe bụ -40 ~ 120 ℃. Butanol bụ otu n'ime rọba a na-ejikarị eme akara mmanụ na O-mgbanaka.

Uru:

· Ezigbo iguzogide mmanụ, mmiri, ihe mgbaze na mmanụ nrụgide dị elu.

· Ezi mkpakọ deflection, eyi iguzogide na elongation.

Ihe ọghọm:

Ọ dịghị mma maka ihe mgbaze pola dị ka ketones, ozone, nitro hydrocarbons, MEK na chloroform. A na-eji ya eme tank mmanụ, mmanụ mmanụ mmanụ na akụkụ roba, karịsịa akụkụ mkpuchi, nke a na-eji mmanụ mmanụ hydraulic mmanụ, mmanụ ụgbọala, mmiri, silicon griiz, mmanụ silicon, mmanụ mmanụ dister, mmanụ ethylene glycol hydraulic mmanụ na mgbasa ozi mmiri ndị ọzọ. Ọ bụ akara rọba kacha eji eme ihe yana ọnụ ala.

FKM

Fluoro Carbon Rubber Nke ọ bụla n'ụdị dị iche iche dabere na ọdịnaya fluorine (usoro monomer) nke molekul fluorine. Igwe ọkụ dị elu dị mma karịa roba silicone, nwere nguzogide kemịkalụ dị mma, iguzogide ọtụtụ mmanụ na ihe mgbaze (ma e wezụga ketone, ester), nguzogide ihu igwe na nguzogide ozone; Oyi na-eguzogide bụ ogbenye, n'ozuzu ojiji nke okpomọkụ nso nke -20 ~ 250 ℃. Usoro pụrụ iche nwere ike idi obere okpomọkụ ruo -40 ℃. Uru:

· Okpomọkụ na-eguzogide 250 ℃

· Na-eguzogide ọtụtụ mmanụ na ihe mgbaze, karịsịa acid niile, aliphatic, aromatic na anụmanụ na mmanụ oriri.

Ihe ọghọm:

· A naghị akwado ya maka ketones, esters nke ịdị arọ molekụla dị ala na ngwakọta nwere nitrate. · Ụgbọ ala, locomotives, engine mmanụ dizel na mmanụ ụgbọala.

SIL

Silicone roba isi yinye bụ nke silicon (-si-O-Si) jikọtara ọnụ. Okpomọkụ dị oke mma, nguzogide oyi, nguzogide ozone, nguzogide ikuku ikuku. Ezigbo ihe mkpuchi ọkụ eletrik. Ike ike nke rọba nkịtị adịghị mma ma ọ nweghị nguzogide mmanụ. Uru:

· Ike tensile ruo 1500PSI na nguzogide akwa ruo 88LBS mgbe emechara ya

· Ezi elasticity na ezigbo mkpakọ mgbagwoju anya

· Ezigbo iguzogide ihe mgbaze na-anọpụ iche

· Magburu onwe okpomọkụ na-eguzogide

· Magburu onwe oyi na-eguzogide

· Magburu onwe iguzogide ozone na oxide ozize

Ọmarịcha ihe mkpuchi ọkụ eletrik

· Ihe mkpuchi ọkụ dị mma na ikpo ọkụ ọkụ

Ihe ọghọm:

A naghị atụ aro ka iji ya mee ihe n'ọtụtụ ihe mgbaze, mmanụ, acid gbadoro ụkwụ na sodium hydroxide diluted. · Akara ma ọ bụ akụkụ rọba a na-eji n'ụlọ ọrụ ngwa ngwa, dị ka ite eletrik, ígwè, akụkụ roba na oven microwave.

· Akara ma ọ bụ akụkụ rọba na ụlọ ọrụ eletrọnịkị, dị ka igodo ekwentị mkpanaaka, ihe na-ama jijiji na DVD, akara na njikọ eriri, wdg.

· Akara n'ụdị ihe ọ bụla metụtara ahụ mmadụ, dịka karama mmiri, isi iyi mmanya, wdg.

Epdm

Ethylene Rubber (PPO) bụ copolymerized site na Ethylene na propylene n'ime agbụ isi ma nwee ezigbo nguzogide okpomọkụ, nguzogide ịka nká, nguzogide ozone na nkwụsi ike, mana enweghị ike ịgbakwunye sọlfọ. Iji dozie nsogbu a, a na-ewebata obere akụkụ nke atọ nke nwere eriri abụọ n'ime isi ihe nke EP, nke nwere ike ịmepụta site na ịgbakwunye sọlfọ na EPDM. N'ozuzu okpomọkụ nso bụ -50 ~ 150 ℃. Nnukwu iguzogide ihe mgbaze pola dị ka mmanya, ketone, glycol na phosphate lipid hydraulic fluids.

Uru:

· Ọmarịcha ihu igwe na nguzogide ozone

· Magburu onwe mmiri na-eguzogide na chemical iguzogide

Enwere ike iji mmanya na-egbu egbu na ketones mee ihe

· Nnukwu uzuoku uzuoku na-eguzogide okpomọkụ, ezigbo impermeability na gas

Ihe ọghọm:

· A naghị atụ aro maka iji nri ma ọ bụ ikpughe na hydrogen aromatic. · Akara maka elu okpomọkụ mmiri vepo gburugburu ebe obibi.

· Akara ma ọ bụ akụkụ maka akụrụngwa ụlọ ịsa ahụ.

Akụkụ rọba na sistemu braking (braking).

· Akara na radiators ( tankị ụgbọ ala).
