Mazhinji mayuniti uye mafekitori anoshandisa akavhurika musanganiswa werabha. Chinhu chayo chikuru ndechekuti ine kuchinjika kukuru uye kufamba, uye inonyanya kukodzera kusanganiswa kweanowanzo siyana erabha, yakaoma rabha, chipanje rabha, nezvimwe.
Kana uchisanganiswa neguyo rakashama, kurongeka kwedosing kunonyanya kukosha. Mumamiriro ezvinhu akajairwa, rabha yakasvibirira inoiswa mugomba remapumburu padivi pevhiri rekutsikirira, uye kureba kunodzorwa kunosvika 2mm (tora 14-inch rubber mixer semuenzaniso) uye roll kwemaminetsi mashanu. Glue yakasvibirira inoumbwa kuva firimu yakatsetseka uye isina gap, iyo yakaputirwa pairi remberi, uye pane imwe chiyero cheglue yakaunganidzwa pane roller. Iyo yakaunganidzwa yerabha inoverengera inosvika 1/4 yehuwandu hwehuwandu hwerabha yakabikwa, uyezve anti-kuchembera maajenti uye accelerator anowedzerwa, uye rabha inodhindwa kakawanda. Chinangwa cheizvi ndechekuita kuti iyo antioxidant uye accelerator iparadzwe zvakaenzana muglue. Panguva imwecheteyo, iyo yekutanga yekuwedzera ye antioxidant inogona kudzivirira iyo inopisa kuchembera chiitiko chinoitika panguva yekupisa kwerabha kusanganiswa. Uye mamwe ma accelerator ane plasticizing mhedzisiro pamusanganiswa werabha. Zinc oxide inobva yawedzerwa. Paunenge uchiwedzera kabhoni nhema, shoma shoma inofanira kuwedzerwa pakutanga, nokuti mamwe marabha mambishi anobuda mupumburu kana carbon black yawedzerwa. Kana paine chiratidzo chekudzima, rega kuwedzera kabhoni nhema, wobva wawedzera kabhoni dema mushure mekunge rabha raputirwa muroller zvakanaka zvakare. Kune nzira dzakawanda dzekuwedzera carbon black. Kunyanya zvinosanganisira: 1. Wedzera kabhoni dema pamwe chete nehurefu hwekushanda kweroller; 2. Wedzera kabhoni dema kusvika pakati pe roller; 3. Iwedzere pedyo kune imwe mugumo webaffle. Mune maonero angu, nzira mbiri dzekupedzisira dzekuwedzera kabhoni dema dzinonyanya kukosha, ndiko kuti, chikamu chete che degumming chinobviswa kubva kune roller, uye hazvibviri kubvisa roller yose. Mushure mekunge musanganiswa werabha wabviswa mupumburu, iyo kabhoni nhema inotsikirirwa zviri nyore kuita maflakes, uye hazvisi nyore kupararira mushure mekukungurutswa zvakare. Kunyanya pakukanya rabha yakaoma, sarufa inomanikidzwa kuita maflakes, ayo anonyanya kuoma kuparadzira murubha. Hapana kunatsiridza kana kuonda kudarika kunogona kushandura yero "homwe" nzvimbo iripo mufirimu. Muchidimbu, kana uchiwedzera kabhoni dema, wedzera zvishoma uye kakawanda. Usatora dambudziko kudira yese carbon black pane roller. Nhanho yekutanga yekuwedzera kabhoni dema ndiyo inokurumidza nguva ye "kudya". Usawedzera softener panguva ino. Mushure mekuwedzera hafu yekabhoni yakasviba, wedzera hafu yekunyorovesa, iyo inogona kukurumidza "kudya". Imwe hafu yekunyorovesa inowedzerwa nekabhoni dema yasara. Mukuita kwekuwedzera hupfu, kureba kwemupumburu kunofanira kudzoreredzwa zvishoma nezvishoma kuchengetedza rabha yakamisikidzwa mukati mechikamu chakakodzera, kuitira kuti poda inongopinda murubha uye inogona kusanganiswa nerubha kusvika pamwero mukuru. Panguva ino, zvinorambidzwa zvachose kutema banga, kuitira kuti usakanganisa kunaka kwekomboni yerubha. Panyaya yekunyorovesa yakawandisa, kabhoni dema uye munyoro anogona zvakare kuwedzerwa mune paste fomu. Stearic asidhi haifanirwe kuwedzerwa nekukurumidza, zviri nyore kukonzera roll off, zviri nani kuiwedzera kana pachine kabhoni dema mumupumburu, uye iyo vulcanizing agent inofanirawo kuwedzerwa pane imwe nguva. Mamwe ma vulcanizing agents anowedzerwawo kana pachine kabhoni dema pane roller. Zvakadai senge vulcanizing agent DCP. Kana kabhoni nhema yese ikadyiwa, DCP inodziirwa yonyungudutswa kuita mvura, inowira mutireyi. Nenzira iyi, huwandu hwevamiriri vevulcanizing mukomboni huchadzikiswa. Nekuda kweizvozvo, mhando yekomboni yerabha inokanganiswa, uye inogona kukonzera kusabikwa vulcanization. Nokudaro, iyo vulcanizing agent inofanira kuwedzerwa panguva yakakodzera, zvichienderana nemhando dzakasiyana-siyana. Mushure mekunge marudzi ese emusanganiswa awedzerwa, zvinodikanwa kuti uwedzere kutendeuka kuita kuti musanganiswa werabha wasanganiswa. Kazhinji, pane "mapanga masere", "mabhegi matatu", "kukunguruka", "mbambo dzakatetepa" uye dzimwe nzira dzekutendeuka.
"Mapanga masere" ari kucheka mapanga pa 45 ° angle pamwe negwara rakafanana reroller, kane kune rumwe rutivi. Iyo yakasara glue yakasvibiswa 90 ° uye yakawedzerwa kune roller. Chinangwa ndechekuti zvinhu zverabha zvinokungurutswa munzira yakatwasuka uye yakatwasuka, izvo zvinoita kuti yunifomu musanganiswa. "Triangle bag" ipurasitiki bhegi rinogadzirwa kuita katatu nesimba reroller. "Kukunguruka" ndiko kucheka banga neruoko rumwe, kukungurutsa zvinhu zverabha muhumburumbira nerumwe ruoko, wozoisa muroller. Chinangwa cheizvi ndechekuita kuti musanganiswa werabha wakaenzana wakasanganiswa. Zvisinei, "triangle bag" uye "rolling" hazvibatsiri kupisa kupisa kwezvinhu zverubha, izvo zviri nyore kukonzera kupisa, uye kushanda nesimba, saka nzira mbiri idzi hadzifaniri kukurudzirwa. Kutora nguva 5 kusvika 6 maminitsi.
Mushure mekunge musanganiswa werabha wanyungudutswa, zvinodikanwa kutetepa musanganiswa werubha. Kudzidzira kwakaratidza kuti mukomboni mutete pass unoshanda zvakanyanya pakupararira kweiyo musanganiswa mukomboni. Iyo yakatetepa-pass nzira ndeyekugadzirisa iyo roller kureba kusvika 0.1-0.5 mm, isa zvinhu zverabha mu roller, uye woirega ichiwira mutireyi yekudyisa. Mushure mekudonha, shandura iyo rubber zvinhu ne 90 ° pane yepamusoro roller. Izvi zvinodzokororwa 5 kusvika 6 nguva. Kana tembiricha yerabha yakanyanyisa, misa pfumbu yakatetepa, uye mirira kuti zvinhu zverabha zvitonhore zvisati zvatetepa kudzivirira zvinhu zverabha kuti zvisapisa.
Mushure mekupfuura kutetepa kwapedzwa, zorora kureba kusvika 4-5mm. Rubber rusati rwaiswa mumotokari, chidimbu chiduku cherubha chinobviswa uye chinoiswa mumarori. Chinangwa ndechekuburitsa kureba kwemupumburu, kuitira kudzivirira mushini wekusanganisa rubber kubva pachisimba pasi pesimba rakakura uye kukuvadza midziyo mushure mehuwandu hwemarubha zvinhu zvakapihwa mu roller. Mushure mokunge zvinhu zverabha zvakatakurwa pamotokari, inofanira kupfuura nemupumburu kamwe chete, uye woiputira pamupumburu wepamberi, ramba uchiishandura kwemaminitsi maviri kusvika ku3, uye udzikinure uye utonhorere munguva. Iyi firimu yakareba 80 cm, 40 cm yakafara uye 0.4 cm mukobvu. Kutonhodza nzira dzinosanganisira kutonhora kwechisikigo uye kutonhora kwetangi remvura inotonhora, zvichienderana nemamiriro echikamu chimwe nechimwe. Panguva imwecheteyo, zvakakosha kudzivisa kusangana pakati pefirimu nevhu, jecha uye imwe tsvina, kuitira kuti irege kukanganisa hutano hwemusanganiswa werubha.
Mukuita kusanganisa, kureba kwema roll kunofanirwa kunyatsodzorwa. Tembiricha inodiwa pakusanganiswa kwemarubha akasiyana-siyana uye kusanganiswa kwemhando dzakasiyana dzekuomarara kwakasiyana, saka tembiricha yeroller inofanirwa kuve nyanzvi maererano nemamiriro chaiwo.
Vamwe vashandi vanosanganisa rabha vane mazano maviri asina kururama anotevera: 1. Vanofunga kuti kana nguva yekusanganisa yakareba, ndipo pakakwirira kunaka kwerabha. Izvi hazvisizvo mukuita, nekuda kwezvikonzero zvinotsanangurwa pamusoro apa. 2. Zvinotendwa kuti kukurumidza kuwanda kweglue yakaunganidzwa pamusoro pe roller inowedzerwa, kukurumidza kusanganiswa kwekukurumidza kuchava. Muchokwadi, kana pasina akaunganidzwa glue pakati pema rollers kana yakaunganidzwa glue idiki zvakanyanya, hupfu huchatsikirirwa nyore mumaflakes uye huchawira mutireyi yekudyisa. Nenzira iyi, kunze kwekukanganisa kunaka kwerabha yakavhenganiswa, tireyi yekudyisa inofanira kucheneswa zvakare, uye Iyo Poda inodonha inowedzerwa pakati pe rollers, iyo inodzokororwa kakawanda, iyo inowedzera nguva yekusanganiswa uye inowedzera basa. intensity. Zvechokwadi, kana kuunganidza glue kwakanyanyisa, kusanganiswa kwehupfu kuchaderedzwa. Zvinogona kuoneka kuti yakawandisa kana kushoma kuunganidza glue hakuna kunaka pakusanganisa. Nokudaro, panofanira kuva nehuwandu hweglue yakaunganidzwa pakati pema rollers panguva yekusanganiswa. Panguva yekukanya, kune rumwe rutivi, poda inosvinwa muglue nekuita kwesimba remagetsi. Somugumisiro, nguva yekusanganiswa inopfupiswa, simba rekushanda rinoderedzwa, uye hutano hwemhando yerubha hwakanaka.
