Zvigadzirwa zverabha zvakavakirwa parabha mbishi uye zvinowedzerwa nehuwandu hwakakodzera hwemacompounding agents. …
1.Rabha yechisikigo kana yekugadzira isina anosanganisa maajenti kana isina vulcanization inosanganiswa inonzi raw rabha. Rabha yechisikigo ine yakanaka yakazara zvivakwa, asi kubuda kwayo hakugone kuzadzisa zvinodiwa neindasitiri, uye haigone kuzadzisa zvimwe zvakakosha kuita zvinodiwa, saka kune akawanda mashandisirwo erabha yekugadzira. …
Compounding agent Kuti uvandudze nekuvandudza zvinhu zvakasiyana-siyana zvezvigadzirwa zverabha, chinhu chinowedzerwa chinodaidzwa kuti compounding agent. Macompounding agents anonyanya kusanganisira vulcanization minzwa, mafirita, vulcanization accelerators, plasticizers, anti-kuchembera vamiririri uye anopupa.
① Basa re vulcanizing agent rakafanana neanorapa mu thermosetting mapurasitiki. Inoita kuti rabha molecular cheni dziumbe dzakachinjika cheni, zvakakodzera kuyambuka-yakabatana, uye ive inetiweki chimiro, nekudaro ichivandudza michina uye yemuviri zvimiro zverabha. Inowanzoshandiswa sulfide sulfur uye sulfide. …
② Iyo yekuzadza ndeyekuvandudza ma mechanic zvimiro zverabha, senge simba, kuoma, kupfeka kuramba uye kusimba. Anonyanya kushandiswa mafirita kabhoni nhema uye machira, mafiibha, uye kunyange waya dzesimbi kana simbi dzakarukwa sezvinhu zvemukati. Kuwedzera mafirita kunogona zvakare kudzikisa huwandu hwerabha mbishi uye kuderedza mutengo werabha. …
③ Mamwe macompounding agents vulcanization accelerators anogona kukurumidza kuita vulcanization uye kugadzirisa vulcanization maitiro; plasticizers anoshandiswa kuwedzera rabha plasticity uye kunatsiridza molding process performance; antioxidants (antioxidants) inoshandiswa kudzivirira kana kunonoka kuchembera kwerabha.
2.Zvimiro uye mashandisirwo ezvigadzirwa zverabha
Zvigadzirwa zverabha zvine hunhu hwepamusoro elasticity, kusimba kwepamusoro, kusimba kwepamusoro uye kushomeka kwepamusoro. Yayo elastic modulus yakaderera kwazvo, chete 1-10 MPa, uye yayo elastic deformation yakakura kwazvo, inosvika 100% kusvika 1000%. Iyo ine yakanakisa kuchinjika uye simba rekuchengetedza simba. Uye zvakare, ine yakanaka kupfeka kuramba, kuvharidzira ruzha, kunyorova uye kuvharisa. Zvisineyi, rabha ine kushomeka kwekupisa uye kutonhora kwekudzivirira (inonamira patembiricha yakakwira, brittle kana yaiswa kuchando), uye inonyungudika muzvinonyungudutsa. …
Muindasitiri, rabha inogona kushandiswa kugadzira matai, static uye anochinja zvisimbiso, vibration damping uye anti-vibration zvikamu, mabhandi ekutakurisa, mabhandi ekutakura uye mapaipi, waya, tambo, magetsi ekudzivirira uye mabhureki zvikamu.
