Kwemakore, kugadzirwa kwema rabha rollers kwakaita kuti michina iome uye otomatiki yemichina yekugadzira michina nekuda kwekusagadzikana kwezvigadzirwa uye kusiyana kwehukuru hwazvo. Kusvika parizvino, mazhinji acho achiri magadzirirwo ekugadzira mayuniti asingachinji. Munguva pfupi yapfuura, vamwe vagadziri vakuru vehunyanzvi vakatanga kugadzira zvinhu kubva pazvinhu zverabha kusvika pakuumba uye kugadzira vulcanization, izvo zvakapetwa kaviri kushanda zvakanaka kwekugadzira uye zvakavandudza zvakanyanya nzvimbo yekushanda uye simba revashandi.
Mumakore achangopfuura, tekinoroji yekuisa jekiseni, kuburitsa, uye kupeta yakaramba ichigadzirwa, uye michina yekuisa rabha muchimiro cherubber roller yakaita kuti kugadzirwa kwerabha roller kuve nemichina uye otomatiki zvishoma nezvishoma. Kushanda kwerabha roller kune simba guru pamuchina wese, uye kwakanyatsoomerera pakushanda kwemaitiro uye mhando yekugadzira. Zvizhinji zvezvigadzirwa zvayo zvakaiswa muzvikamu zvakanaka. Pakati pazvo, kusarudzwa kwezvinhu zverabha nepurasitiki uye kudzora kurongeka kwechigadzirwa ndizvo zvakakosha. Ruoko rwerabha rwerabha roller harubvumirwi kuva netsvina, mabhurugwa nemabhuru, tisingatauri mavanga, zvikanganiso, migero, matsemuka uye masiponji emuno nezvimwe zvinhu zvakapfava uye zvakaoma. Nechikonzero ichi, rabha roller inofanira kunge yakachena uye yakanyatsochenjerera mukugadzirwa kwese, kuitira kuti ishande pamwe chete uye igadziriswe. Maitiro ekubatanidza rabha purasitiki nesimbi, kunama, kuumba jekiseni, vulcanization uye kukuya ave maitiro epamusoro-soro.
Kugadzirira rabha
Kune maroller erabha, kusanganiswa kwerabha ndicho chinhu chinonyanya kukosha. Kune mhando dzinopfuura gumi dzezvinhu zverabha zvemaroller erabha zvinotangira parabha yechisikigo uye rabha yekugadzira kusvika kune zvinhu zvakakosha. Rudzi rwerabha iri pakati pe25%-85%, uye kuoma kwayo ivhu (0-90) degrees, iro rinopararira zvakasiyana-siyana. Saka, nzira yekusanganisa makemikari aya zvakaenzana yave dambudziko guru. Nzira yakajairika ndeyekushandisa chigayo chakavhurika chekusanganisa nekugadzirisa muchimiro chemhando dzakasiyana dzemaster batches. Mumakore achangopfuura, makambani ari kuramba achichinja kuita internal mixers kuti agadzire makemikari erabha kuburikidza nekusanganisa kwakapatsanurwa.
Mushure mekunge zvinhu zverabha zvasanganiswa zvakaenzana, rabha inofanira kusefa nefirita yerabha kubvisa tsvina iri murabha. Wobva washandisa calender, extruder, nemuchina we laminating kugadzira firimu kana strip isina mabubbles uye tsvina yerabha roller. Usati wagadzira, mafirimu aya ne glue strips dzinofanira kuongororwa zvakanyanya kuti udzikise nguva yekupaka, kuchengetedza nzvimbo itsva uye kudzivirira kunamira uye kushanduka kwe extrusion. Nekuti akawanda ema rabha roller haana kuumbwa, kana paine tsvina nemabubbles pamusoro perabha, mablister anogona kuoneka kana pamusoro payo pagayiwa mushure mekuvhunika, izvo zvichaita kuti rabha roller yese igadziriswe kana kutobviswa.
