Ọ bụ akara rọba kachasị eji eme ihe ma dị ọnụ ala.

FKM

Fluoro Carbon Rubber Ụdị ọ bụla dị iche iche dabere na ọdịnaya fluorine (usoro monomer) nke molekul fluorine. Nguzogide okpomọkụ dị elu dị mma karịa roba silicone, nwere ezigbo nguzogide kemịkalụ, iguzogide ọtụtụ mmanụ na ihe mgbaze (ma e wezụga ketone, ester), nguzogide ihu igwe na nguzogide ozone; Nguzogide oyi adịghị mma, ojiji zuru oke nke oke okpomọkụ bụ -20~250 ℃. Usoro pụrụ iche nwere ike iguzogide obere okpomọkụ ruo -40 ℃. Uru:

· Nguzogide okpomọkụ ruo 250 ℃

· Na-eguzogide ọtụtụ mmanụ na ihe mgbaze, ọkachasị asịd niile, mmanụ aliphatic, aromatic na mmanụ anụmanụ na akwụkwọ nri

Ihe ọghọm:

· A naghị atụ aro ya maka ketones, esters nwere obere ibu molekul na ngwakọta nwere nitrate. · Ụgbọala, locomotives, injin dizel na sistemụ mmanụ ọkụ.

SIL

A na-eji silicon (-si-O-Si) ejikọtara ọnụ mee ihe dị ka isi ihe eji ejikọta rọba silicone. Ọ na-eguzogide okpomọkụ nke ọma, ọ na-eguzogide oyi, ọ na-eguzogide ozone, ọ na-eguzogide ịka nká. Ọ na-arụ ọrụ dị mma maka mkpuchi eletriki. Ike nrụgide nke rọba nkịtị adịghị mma ma ọ nweghị ike iguzogide mmanụ. Uru:

· Ike nrụgide ruo 1500PSI na iguzogide ndọda ruo 88LBS mgbe emechara nhazi ahụ

· Ezigbo nkwụsịtụ na mgbagọ mkpakọ dị mma

· Ezigbo iguzogide ihe mgbaze na-anọpụ iche

· Ezigbo iguzogide okpomọkụ

· Ezigbo iguzogide oyi

· Ezigbo iguzogide mbuze ozone na oxide

Ọrụ mkpuchi ọkụ eletrik dị mma nke ukwuu

· Mkpuchi okpomọkụ na mwepu okpomọkụ dị mma

Ihe ọghọm:

· A naghị atụ aro ka e jiri ya mee ihe n'ọtụtụ ihe mgbaze, mmanụ, asịd a gwakọtara agwakọta na sodium hydroxide a gwakọtara agwakọta. · Ihe mkpuchi ma ọ bụ akụkụ rọba eji eme ihe n'ụlọ ọrụ ngwa ụlọ, dị ka POTS eletriki, ígwè, akụkụ rọba n'ime oven microwave.

· Ihe mkpuchi ma ọ bụ akụkụ rọba n'ime ụlọ ọrụ eletrọniki, dịka igodo ekwentị mkpanaaka, ihe na-amịkọrọ ihe mberede na DVD, ihe mkpuchi na njikọ eriri, wdg.

· Na-emechi ụdị ihe niile metụtara ahụ mmadụ, dịka karama mmiri, isi iyi mmiri ọṅụṅụ, wdg.

Epdm

A na-eji Ethylene Rubber (PPO) eme ka ọ bụrụ nke e ji kpụọ polima site na Ethylene na propylene n'ime isi yinye ma nwee ezigbo iguzogide okpomọkụ, iguzogide ịka nká, iguzogide ozone na nkwụsi ike, mana enweghị ike itinye sọlfọ. Iji dozie nsogbu a, a na-etinye obere akụkụ nke atọ nwere agbụ abụọ n'ime isi yinye EP, nke enwere ike ịmepụta site na itinye sọlfọ na EPDM. Oke okpomọkụ izugbe bụ -50~150 ℃. Ọ dị mma iguzogide ihe mgbaze polar dị ka mmanya, ketone, glycol na phosphate lipid hydraulic fluids.

Uru:

· Ezigbo iguzogide ihu igwe na iguzogide ozone

· Mmiri dị mma na iguzogide kemịkalụ

· Enwere ike iji mmanya na ketones mee ihe

· Nguzogide uzuoku dị elu, ezigbo mgbochi mmiri na gas

Ihe ọghọm:

· A naghị atụ aro ya maka iji nri ma ọ bụ ikpughe ya na hydrogen na-esi ísì ụtọ. · A na-emechi ya maka gburugburu ebe mmiri na-ekpo ọkụ nke ukwuu.

· Ihe mkpuchi ma ọ bụ akụkụ maka ngwa ụlọ ịsa ahụ.

· Akụkụ rọba dị na sistemụ brek (brek).

· Mkpuchi na radiators (tankị mmiri ụgbọ ala).
