Ihe ngwọta maka nsogbu a bụ ịhọrọ roba raw nke nwere viscosity dị ihe dị ka 70, na iji rọba raw na-ekesa nkesa dị warara dị warara, wee gbakwunye obere ihe nke Brazil ma ọ bụ fluorine wax ma ọ bụ polyethylene dị arọ nke dị ala n'ime usoro ahụ, nke nwekwara ike dozie ihe mgbagwoju anya.

Ihe 3. Banyere obere ntụpọ ọcha na roba na-ejikọta

Ọ bụ n'ihi na ụfọdụ powder dispersion nke fluorine roba compounding gị n'ụlọnga abụghị edo, ma ọ bụ n'ihi na ntụ ntụ caking, dị ka acid absorbers calcium hydroxide, magnesium oxide na diatomaceous ụwa, barium sulfate, wdg, ihe ngwọta, iji gbochie compounding gị n'ụlọnga mmiri na-ewusi mkpa ngafe usoro.

Point 4. Ngwaahịa dị mfe ịdọka

Ihe na-akpata, nwere ike ịbụ kwa oké burr, trimming mgbe tearing, ma ọ bụ ebu na oke uko, nke ebu burr akụkụ na-rapaara na ebu, mfe si ngwaahịa na burr tupu tearing, na-enweghị isi ike mgbe ịmalite ebu, mfe akwa ngwaahịa. Mgbe ụfọdụ nhazi oghere nke ebu na-esi ike, ma ọ bụ ihe nrapado na-arapara n'akpụkpọ ahụ, na mgbe vulcanization gwụchara, ọ na-akpata ihe isi ike iwepụ ebu ahụ wee dọwaa ngwaahịa ahụ ngwa ngwa. Na mgbakwunye, okpomọkụ vulcanization dị oke elu, nke ga-emekwa ka ngwaahịa ndị ahụ bụrụ ihe na-agbaji ma dị mfe ịdọka. N'ihi na ndị dị n'elu abnormality, ọ nwere ike na-edozi site na ndị na-esonụ akụkụ: ebu nhazi nkenke kwesịrị ịdị mma oghere roughness Ra na-erughị 0,8, kwesịrị ekwesị ọdịiche ekwesịghị ịbụ oke ibu, vulcanization okpomọkụ akara ekpe n'etiti 170 degrees dị mma, na roba ihe na-atụ kwesịrị ịbụ ihe ziri ezi.

Point 5. Mbelata na mgbawa nsogbu

Ọ bụ n'ihi nrụgide a na-ewepụ mgbe a na-emepe ihe ọkpụkpụ ahụ, fluorine rubber shrinkage, na akụkụ burr na-arapara n'ime ihe dị n'ime ya na elu dị n'etiti, ya mere n'etiti akụkụ ngwaahịa na burr na-emepụta ike ike, nke mere na ngwaahịa na burr kewara, mgbe a na-agbasa oghere mgbawa na akụkụ ngwaahịa, ọ na-eme ka nkwụsịtụ na ihe mgbagwoju anya. Ihe ngwọta bụ iji belata okpomọkụ vulcanization nke ọma, họrọ Menny viscosity n'ihe dịka 70 [ML1+4] 121 degrees, ebe ogo ogo ebu kwesịrị ekwesị kwesịrị ekwesị, ọ bụghị nke dị nro na nke siri ike.

Point 6. Edge dị ka ọkụ

Ọ bụ vulcanization okpomọkụ bụ oke elu, karịsịa oké ngwaahịa, kwesịrị ekwesị iji belata vulcanization okpomọkụ nwere ike imeri.

Ihe 7. Enwere akara na nkwonkwo

I t bụ n'ihi n'apata akụkụ nke nrapado ihe na-adịghị kpamkpam fused ọnụ, ma ọ bụ n'ihi na nrapado warara nwere adịghị ọcha ma ọ bụ mmanụ fouling, ihe ngwọta bụ na-na preformed nrapado warara na nchekwa, njem, loading gluu dị ọcha, iji gbochie mmetọ.

Isi 8. Enweghị gluu

Ọ na-ejikọta ya na nhazi nke ebu na mmiri mmiri nke gluu. Akpụkpọ ahụ mechiri emechi nwere ike ịmepụta enweghị gluu karịa ihe a na-emeghe. Ihe ngwọta bụ imeziwanye mmiri mmiri nke rọba ahụ ma mepee oghere ikuku ikuku n'ime oghere ebu.

Point 9. Nrụpụta ngwaahịa

Ọ bụ n'ihi na fluorine rubber shrinkage ọnụego bụ nnukwu, mgbe ịkpụzi ngwaahịa shrinkage anisotropy, ọnụọgụ nke thermal mgbasawanye nke roba dị iche iche ntụziaka dị iche iche, abụọ vulcanization usoro ga-etolite ọzọ cross-njikọ, karịsịa a ngalaba nke vulcanization n'okpuru sọlfọ, abụọ vulcanization nke ngwaahịa, ọzọ doro anya deformation, nwere ike na-enye ohere zuru ezu cross oge, abụọ na-ezere oge cross. vulcanization nke nrụrụ ngwaahịa.

Point 10.Mold unyi serious phenomenon

Anyị na-ejikarị 26 ụdị fluorine roba, phenol vulcanization usoro, na vulcanization usoro ga-eme HF, ọ bụ nnọọ ike acid, nwere nnukwu corrosive mmetụta na ebu, usoro ịgbakwunye acid absorbent bụ banye na HF eme, iji gbochie mmetọ nke ebu. Ihe ngwọta bụ iji calcium hydroxide zuru ezu na magnesium oxide dị ka usoro ahụ si dị, usoro ọgwụgwọ bụ n'ozuzu akụkụ 6 na akụkụ 3, a pụkwara ịgbakwunye wax Brazil na usoro ahụ, nke nwere ike ịkwaga n'elu rọba n'oge vulcanization iji mepụta ihe nkiri iji gbochie ebu ahụ ka ọ ghara imetọ ya.

Enwere ike idozi nsogbu iri a na-ahụkarị na mmepụta na nhazi nke roba fluorine site na usoro dị iche iche.
