2. Njirimara kemịkalụ:

Silikoni:

Silica gel bụ elastomer nke na-ekpo ọkụ, nke na-adịghị edozi na mmiri, ọ dịghịkwa emeghachi omume na ihe ndị ọzọ ma e wezụga alkali siri ike na hydrofluoric acid.

Silica gel nwere esemokwu dị mma na nguzogide okpomọkụ, agaghị agbaze mgbe vulcanization gasịrị, ọ dịghịkwa eguzogide ozone.

Nitrile:

Ezi mmanụ eguzogide na ịka nká na-eguzogide, ọ ga-eji na 120 ℃ ikuku ma ọ bụ 150 ℃ mmanụ ruo ogologo oge. Tụkwasị na nke ahụ, ọ na-enwekwa nguzogide mmiri, ikuku ikuku na njirimara njikọ dị mma.

Ọdịmma ya bụ nguzogide okpomọkụ dị ala, nguzogide ozone, na ngbanwe dị ntakịrị.

PVC:

Nnukwu esemokwu na-eguzogide kemịkalụ, nguzogide corrosion mana ọ bụghị nguzogide ozone. N'ime acid siri ike dị ka sulfuric acid gbadoro anya, nitric acid ga-emebi emebi, enweghị ike ịkpọtụrụ hydrocarbons aromatic na ihe hydrocarbon chlorinated.

3. Usoro ndọtị

Silica gel: ojii na-acha ọcha na-ahụkarị, nwere ike ịcha agba, enwere ike ịhazi ya

Nitrile: oji na-acha ọcha na-ahụkarị, enweghị ike ime agba, elu elu nwere ike ịcha electroplated

PVC: transperent agba, nwere ike ime agba, agba siri ike ọkara transperent agba nwere ike ịbụ

TPE: ụcha transperent, enwere ike ime agba, agba siri ike ọkara transperent nwere ike ịbụ, enwere ike ịhazi ya.

N'ime ha, nitrile nwere ike ime ka elu matte, na electroplating nwere ike ime ka elu ahụ ruo elu dị mma;
