Indasitiri yerabha inosanganisira akasiyana mazwi ehunyanzvi, pakati peiyo nyowani latex inoreva chena lotion yakachekwa kubva pamiti yerabha.
Rabha yakajairika yakakamurwa kuita 5, 10, 20, uye 50 particle rubber, pakati payo SCR5 inosanganisira maviri marudzi: emulsion rubber uye gel rabha.
Mukaka chiyero chekunamira chinogadzirwa nekuomesa zvakananga, granulating, uye kuomesa latex, nepo kuseta yakajairwa adhesive inogadzirwa nekutsikirira, granulating, uye kuomesa mweya wakaomeswa firimu.
Mooney viscosity chiratidzo chekuyera torque inodiwa pakutenderera kwerotor mune rabha mold cavity pasi pemamiriro chaiwo.
Therabha yakaoma zviri mukati zvinoreva magiramu anowanikwa nekuomesa 100g ye latex mushure mekuoma kweasidhi.
Rubber yakakamurwa kuitaraw rabha uyevulcanized rabha, iyo yekare ichiva rabha mbishi uye yekupedzisira ichive yakasanganiswa rabha.
Mushonga wekusanganisa ikemikari yakawedzerwa kune raw rabha kuvandudza kushanda kwezvigadzirwa zverabha.
Synthetic rubber i polymer yakanyanya elastic yakagadzirwa ne polymerizing monomers.
Recycled rabha chinhu chakagadzirwa kubva kumarara erabha zvigadzirwa uye vulcanized rabha tsvina.
Vulcanizing agents inogona kukonzera rubber cross-linking, ukukupisa ndiko kuitika nguva isati yakwana yevulcanization phenomenon.
Reinforcing agents uyefillers zvichiteerana kuvandudza zvinhu zvemuviri zverabha uye kuderedza mari.
Zvinyoro zvinyoro or plasticizers kuwedzera rabha plasticity, apokuchembera kwerabha ndiyo nzira yekurasikirwa zvishoma nezvishoma nezvinhu zverubha.
Antioxidants kunonoka kana kurambidza kuchembera kwerabha uye yakakamurwa kuita makemikari uye emuviri ekurwisa kuchembera.
Frost spraying uyekupfapfaidza sarufa tarisa kune chiitiko chesarufa uye zvimwe zvinowedzera zvinopfapfaidza kunze uye sarufa inonaya uye crystallizing, zvichiteerana.
Plasticity ndiyo nzira yekushandura raw rabha kuita zvinhu zvepurasitiki, izvo zvinogona kuchengetedza deformation pasi pekunetseka.
Kusanganisa inzira yekuwedzera chinhu chinosanganisa kune rabha kuita musanganiswa werabha, ukucoating inzira yekuisa slurry pamusoro pejira.
Rolling inzira yekugadzira semi-akapedza mafirimu kana matepi kubva kune yakasanganiswa rabha. Iyo tensile kushushikana, yakanyanya tensile kushushikana, uye kureba panguva yekuzorora kunoratidza kushomeka kuramba, kukuvara kwekurwisa, uye deformation maitiro e vulcanized rabha, zvichiteerana.
kubvarura simba inoratidza kugona kwezvishandiso kuramba kupararira kwekuputika, ukurabha kuoma uyekupfekamiririra kugona kwerabha kuramba deformation uye pamusoro kupfeka, zvichiteerana.
Rubberdensityzvinoreva kuwanda kwerabha pavhoriyamu yeyuniti.
Kuramba kuneta inoreva kuchinja kwemaitiro uye maitiro erabha pasi peperiodic ekunze masimba.
Kukura kunoreva maitiro ekupaka machira erabha, uye nguva yekukura inotangira pakusimba kwelatex kusvika pakupera mvura.
Shore A kuoma: Kuomarara kunoreva kugona kwerabha kurwisa kupindira kwekunze, kunoshandiswa kuratidza chiyero chekuoma kwerabha. Kuoma kweshore kwakakamurwa kuita A (kuyera rabha yakapfava), B (kuyera semi-rigid rabha), uye C (kuyera rabha rigid).
Kusimba simba: Kusimba kwesimba, kunozivikanwawo sesimba rekusimba kana kuti simba rekusimba, zvinoreva simba pachikamu chechikamu chinoiswa parabha kana yadhonzwa nepakati, inoburitswa muMpa. Kusimba kwesimba chiratidzo chakakosha chekuyera simba remagetsi rerubha, uye yakakura kukosha kwayo, zviri nani kusimba kwerabha.
Tensile elongation panguva yekuzorora, inozivikanwawo sekurebesa, inoreva chiyero chehurefu hunowedzerwa nekudhonzwa kwerabha kana yadhonzwa kureba kwayo kwepakutanga, inotaridzwa sechikamu (%). Chiratidzo chekushanda chekuyera mapurasitiki erabha, uye kukwirira kwakakwirira kunoratidza kuti rabha ine yakapfava manyoro uye yakanaka plastiki. Nekuita kwerabha, inoda kuve neyakakodzera kureba, asi yakawandisa haina kunaka zvakare.
Rebound rate, inozivikanwawo serebound elasticity kana kukanganisa elasticity, chinhu chakakosha chekuita chiratidzo chekuyera elasticity yerabha. Chiyero chehurefu hwekudzokera kuhurefu hwepakutanga paunoshandisa pendulum kubata rabha pane imwe urefu hunodaidzwa kuti rebound rate, inotaridzwa sechikamu (%). Iyo yakakura kukosha, iyo yakakwirira iyo elasticity yerabha.
Bvisa zvachose deformation, inozivikanwawo sechigarire deformation, chiratidzo chakakosha chekuyera elasticity yerabha. Ireshiyo yehurefu hwakawedzerwa nechikamu chakaremara cherabha mushure mekunge yatambanudzwa uye yakadhonzwa nepakati uye yakamiswa kweimwe nguva yenguva (kazhinji maminitsi matatu) kusvika pahurefu hwepakutanga, inoratidzwa sechikamu (%). Iyo diki dhayamita yayo, zviri nani iyo elasticity yerabha. Pamusoro pezvo, iyo elasticity yerabha inogona kuyerwa zvakare nekumanikidza zvachose deformation.
