Kusanganisa ndeimwe yenhanho dzakakosha uye dzakaoma mukugadzirisa rubber.Iyo zvakare imwe yemaitiro anonyanya kutarisana nekushanduka kwemhando.Unhu hwemusanganiswa werubha unobata zvakananga kunaka kwechigadzirwa.Nokudaro, zvakakosha zvikuru kuita basa rakanaka rekusanganisa rubber.
Semusanganisi werabha, ungaite sei basa rakanaka rekusanganisa rabha?Ini ndinofunga pamusoro pekunyatsogona ruzivo rwunodiwa rwemhando yega yega yerabha, senge maitiro ekusanganisa uye kutevedzana kwedosi, zvakakosha kushanda nesimba, kufunga nesimba, uye kusanganisa rabha nemoyo.Nenzira iyi chete ndiyo inonyanya kunyungudutsa rabha.
Kuve nechokwadi chemhando yerabha yakasanganiswa panguva yekusanganiswa, zvinotevera zvinofanirwa kuitwa:
1. Mhando dzose dzezvigadzirwa zvine diki dosage asi hukuru hukuru hunofanirwa kusanganiswa zvakakwana uye zvakaenzana zvakasanganiswa, zvikasadaro zvinokonzeresa kupisa kwerabha kana kusabikwa vulcanization.
2. Kusanganiswa kunofanira kuitwa zvakanyatsoenderana nemitemo yekusanganiswa uye kurongeka kwekudya.
3. Nguva yekusanganiswa inofanira kunyatsodzorwa, uye nguva haifaniri kunge yakareba kana kuti pfupi.Nenzira iyi chete inogona kuvimbiswa kuti plastiki yerabha yakasanganiswa.
4. Usarasa iyo yakawanda kabhoni dema uye fillers, asi shandisa ivo kumusoro.Uye chenesa tireyi.
Hongu, pane zvakawanda zvinokanganisa kunaka kwerabha yekomboni.Nekudaro, iwo chaiwo maratidziro ndeasina kupararira kupararira kweanosanganisa agent, frost spray, kupisa, nezvimwe, izvo zvinogona kucherechedzwa nemeso.
Kusaenzana kupararira kweagent agent Pamusoro pezvimedu zvekugadzirisa agent pamusoro pemusanganiswa werubha, cheka firimu nebanga, uye pachava nekubatanidza majenti emhando dzakasiyana-siyana pamuchinjikwa-chikamu chemushonga werubha.Mushonga wacho unosanganiswa zvakaenzana, uye chikamu chacho chiri nyore.Kana kupararira kusina kuenzana kwemugadziri wemusanganiswa hakugone kugadziriswa mushure mekunatswa kwakadzokororwa, roller rubber inoraswa.Naizvozvo, musanganisi werabha anofanirwa kunyatsotevedzera mirairo yemaitiro panguva yekushanda, uye nguva nenguva, tora iyo firimu kubva kumagumo ese uye nepakati peiyo roller kuti uone kana iyo inosanganisa mumiriri yakapararira zvakaenzana.
Frosting, kana isiri dambudziko rekugadzira fomu, zvino inokonzerwa nehurongwa husina kunaka hwekuita dosing panguva yekusanganisa, kana kusaenzana kusanganisa uye agglomeration yemusanganiswa wemumiriri.Naizvozvo, zvinodikanwa kunyatso kudzora nzira yekusanganisa kudzivirira kuitika kwezviitiko zvakadaro.
Kupisa ndeimwe yematambudziko akanyanya kukosha mukusanganisa maitiro.Mushure mekunge iyo rubber yapiswa, pamusoro kana chikamu chemukati chine elastic yakabikwa rubber particles.Kana kupisa kuri kudiki, kunogona kugadziriswa neiyo yakaonda pass nzira.Kana kupisa kwacho kwakakomba, zvinhu zverabha zvinoraswa.Kubva pakuona kwemaitiro ekugadzirisa, kupisa kwekomboni yerubha kunonyanya kukanganiswa nekupisa.Kana tembiricha yemusanganiswa werubha yakanyanyisa, iyo raw raw, vulcanizing agent uye accelerator ichaita panguva yekusanganiswa, ndiko kuti, kupisa.Mumamiriro ezvinhu akajairika, kana huwandu hwerubha panguva yekusanganiswa hwakanyanya uye kutonhora kwemupumburu kwakanyanyisa, kutonhora kwerubha kuchawedzera, zvichiita kuti kupisa.Ehe, kana kutevedzana kwekudyisa kusina kunaka, kuwedzera panguva imwe chete yevulcanizing agent uye accelerator inokonzerawo kupisa.
Kuchinja kwekuoma zvakare chinhu chakakosha chinokanganisa kunaka kwemusanganiswa werabha.Mishonga yekuoma kwakafanana inowanzosanganiswa nekuoma kwakasiyana, uye mamwe akatoparadzana.Izvi zvinonyanya kukonzerwa nekusaenzana kusanganiswa kwekomboni yerubha uye kupararira kwakashata kwemusanganisi.Panguva imwecheteyo, kuwedzera zvishoma kana kupfuura kabhoni dema kunokonzerawo kushanduka mukuoma kwekomboni yerabha.Nekune rumwe rutivi, kuyera kusiri iko kwemusanganiswa wemusanganiswa kunokonzeresa kuchinjika mukuoma kwekomboni yerabha.Zvakadai sekuwedzera kweiyo vulcanizing agent uye accelerator kabhoni dema, kuoma kwekomboni yerabha kuchawedzera.Iyo yakapfava uye yakasvibirira rabha inoyerwa zvakanyanya, uye kabhoni dema ishoma, uye kuoma kwekomboni yerabha kunova kudiki.Kana nguva yekusanganiswa yakareba, kuoma kwekomboni yerubha kunoderera.Kana nguva yekusanganisa ipfupi, musanganiswa unoomesa.Nokudaro, nguva yekusanganiswa haifaniri kunge yakareba kana kuti pfupi.Kana kusanganiswa kwakareba, kuwedzera pakuderera kwekuoma kwerabha, simba rekusimba rerubha rinoderera, kureba panguva yekuzorora kuchawedzera, uye kuramba kuchembera kunoderera.Panguva imwecheteyo, inowedzerawo simba rekushanda kwevashandi uye rinopedza simba.
Nokudaro, kusanganiswa kunongoda kukwanisa kuparadzira zvakakwana zvakasiyana-siyana zvinosanganiswa mumucheka werabha, uye kuve nechokwadi chezvinodiwa zvemuviri uye zvemagetsi uye zvinodiwa zvecalendering, extrusion uye mamwe maitiro ekushanda.
Semusanganisi werabha ane hunyanzvi, haangove ane pfungwa yakasimba yemutoro, asi zvakare anofanira kujairana neakasiyana mbichana rubber uye mbishi zvinhu.Ndiko kuti, kwete chete kunzwisisa mabasa avo uye zvivakwa, asiwo kukwanisa kudoma nemazita avo pasina mavara, kunyanya kune makomisheni ane chitarisiko chakafanana.Semuenzaniso, magnesium oxide, nitric oxide uye calcium hydroxide, yakakwirira-inodzivirira kabhoni dema, inokurumidza-extrusion kabhoni dema uye semi-yakasimbiswa kabhoni dema, pamwe neyemumba nitrile-18, nitrile-26, nitrile-40 zvichingodaro.
