Ọtụtụ ụzọ a na-ejikarị achọpụta rọba

1. Nguzogide ule mmụba ibu dị arọ nke ọkara

A pụrụ ịnwale ihe e ji emechara, tinye ya n'ime otu ma ọ bụ ọtụtụ ihe ndị a họọrọ, tụọ ya mgbe oge na okpomọkụ ụfọdụ gasịrị, a pụkwara ịchọpụta ụdị ihe ahụ dabere na ọnụego mgbanwe ibu na ọnụego mgbanwe siri ike.

Dịka ọmụmaatụ, mikpuo n'ime mmanụ ogo 100 ruo awa iri abụọ na anọ, NBR, rọba fluorine, ECO, CR nwere obere mgbanwe n'ịdị mma na ike, ebe NR, EPDM, SBR karịrị okpukpu abụọ n'ịdị arọ ma na-agbanwe nke ukwuu n'ịdị ike, mmụba olu ahụ doro anya.

2. Nnwale ịka nká nke ikuku ọkụ

Were ihe nlele sitere na ngwaahịa emechara, tinye ha n'ime igbe ịka nká maka otu ụbọchị, ma lelee ihe merenụ mgbe ịka nká gasịrị. Enwere ike ịbawanye ịka nká nwayọ nwayọ. Dịka ọmụmaatụ, CR, NR, na SBR ga-adị nro na ogo 150, ebe NBR EPDM ka na-agbanwe agbanwe. Mgbe okpomọkụ ruru ogo 180, NBR nkịtị ga-adị nro; HNBR ga-adịkwa nro na ogo 230, roba fluorine na silicone ka nwere ezigbo njupụta.

3. Usoro ọkụ

Were obere ihe nlele ma kpọọ ya ọkụ n'ikuku. Lee ihe merenụ.

N'ozuzu, rọba fluorine, CR, na CSM enweghị ọkụ, ọ bụrụgodị na ire ọkụ ahụ na-ere ọkụ, ọ pere mpe karịa NR na EPDM izugbe. N'ezie, ọ bụrụ na anyị eleba anya nke ọma, ọnọdụ ọkụ, agba, na isi na-enyekwa anyị ọtụtụ ozi. Dịka ọmụmaatụ, mgbe ejikọtara NBR/PVC na gluu, mgbe enwere isi ọkụ, ọkụ ahụ na-agbapụta ma yie ka ọ dị ka mmiri. Ọ dị mkpa ịmara na mgbe ụfọdụ gluu na-egbochi ire ọkụ mana nke na-enweghị halogen ga-ewepụkwa onwe ya n'ọkụ ahụ, nke a ga-akọwa site n'ụzọ ndị ọzọ.

4. Ịtụle ike ndọda kpọmkwem

Jiri nha eletrọniki ma ọ bụ nhazi nyocha, nke ruru gram 0.01, tinyekwara otu iko mmiri na ntutu isi.

N'ozuzu, rọba fluorine nwere ike ndọda kachasị ukwuu, karịa 1.8, ọtụtụ n'ime ngwaahịa CR ECO nwere oke dị elu karịa 1.3. Enwere ike ịtụle gluu ndị a.

5. Usoro okpomọkụ dị ala

Were ihe nlele sitere na ngwaahịa emechara ma jiri ice kpọrọ nkụ na mmanya iji mepụta gburugburu ebe dị mma maka cryogenic. Mikpuo ihe nlele ahụ n'ebe dị obere okpomọkụ maka nkeji 2-5, nwee mmetụta dị nro na ike na okpomọkụ ahọpụtara. Dịka ọmụmaatụ, na -40 degrees, a na-atụnyere otu ihe ahụ dị elu na okpomọkụ na-eguzogide mmanụ silica na roba fluorine, gel silica dịkwa nro.
