Mayunitsi mazhinji nemafekitori anoshandisa maovheni erabha akavhurika. Chinhu chikuru chayo ndechekuti ine kuchinjika kukuru uye kufamba-famba, uye inonyanya kukodzera kusanganisa rabha dzakasiyana-siyana, rabha rakaoma, rabha rechiponji, nezvimwewo.
Pakusanganisa neguyo rakavhurika, kurongeka kwemuyero kwakakosha zvikuru. Mumamiriro ezvinhu akajairwa, rabha isina kugadzirwa inoiswa mugomba remupumburu parutivi rumwe rwevhiri rekudzvanya, uye daro remupumburu rinodzorwa painenge 2mm (tora muchina wemusanganiswa werabha we 14-inch semuenzaniso) wobva wamonera kwemaminitsi mashanu. Guruu risina kugadzirwa rinoumbwa kuita firimu rakatsetseka uye risina mupumburu, iro rinoputirwa paroller yekumberi, uye pane huwandu hwakati hweguruu rakaunganidzwa paroller. Rabha rakaunganidzwa rinoita chikamu chimwe muzvina chehuwandu hwerabha risina kugadzirwa, uye zvino mishonga inodzivirira kukwegura nemidziyo yekumhanyisa inowedzerwa, uye rabha inonamirwa kakawanda. Chinangwa cheizvi ndechekuita kuti antioxidant ne accelerator zviparadzirwe zvakaenzana muguruu. Panguva imwe chete, kuwedzera kwekutanga kwe antioxidant kunogona kudzivirira chiitiko chekukwegura kwekupisa kunoitika panguva yekusanganiswa kwerabha nekupisa kwakanyanya. Uye mamwe ma accelerator ane mhedzisiro yepurasitiki pa rabha. Zinc oxide inowedzerwa. Pakuwedzera kabhoni nhema, huwandu hushoma hunofanira kuwedzerwa pakutanga, nekuti mamwe ma rabha asina kugadzirwa anobuda muroller nekukurumidza kana kabhoni nhema yawedzerwa. Kana paine chiratidzo chekuti rabha haina kuputirwa, rega kuwedzera kabhoni nhema, wobva wawedzera kabhoni nhema mushure mekunge rabha yaputirwa zvakanaka zvakare. Kune nzira dzakawanda dzekuwedzera kabhoni nhema. Zvikuru zvinosanganisira: 1. Wedzera kabhoni nhema pahurefu hwebasa reroller; 2. Wedzera kabhoni nhema pakati peroller; 3. Wedzera pedyo nemugumo mumwe webaffle. Mukufunga kwangu, nzira mbiri dzekupedzisira dzekuwedzera kabhoni nhema ndidzo dzinonyanya kunaka, kureva kuti, chikamu chekubvisa gumming chete ndicho chinobviswa kubva muroller, uye hazvigoneke kubvisa roller yese. Mushure mekunge rabha yabviswa paroller, kabhoni nhema inodzvanywa nyore nyore kuita flakes, uye hazvisi nyore kupararira mushure mekumoneredzwa zvakare. Kunyanya kana uchikanya rabha yakaoma, sarufa inodzvanywa kuita flakes, izvo zvakaoma zvikuru kuparadzira murabha. Kugadzirisa zvakare kana thin pass hazvigone kuchinja nzvimbo yeyero "pocket" iripo mufirimu. Muchidimbu, kana uchiwedzera kabhoni nhema, wedzera zvishoma uye kakawanda. Usazvinetse kudurura kabhoni nhema yese paroller. Danho rekutanga rekuwedzera kabhoni nhema ndiyo nguva inokurumidza "kudya". Usawedzera chinonyorovesa panguva ino. Mushure mekuwedzera hafu yekabhoni nhema, wedzera hafu yechinyorovesa, izvo zvinogona kukurumidzisa "kudya". Imwe hafu yechinyorovesa inowedzerwa nekabhoni nhema yasara. Mukuwedzera hupfu, daro rekutenderera rinofanira kuderedzwa zvishoma nezvishoma kuti rabha iri mukati mehuwandu hwakakodzera, kuitira kuti hupfu hupinde murabha uye hugone kusanganiswa nerabha kusvika padanho rakanyanya. Padanho iri, zvinorambidzwa chose kucheka banga, kuitira kuti zvisakanganise kunaka kwerabha. Kana paine chinonyorovesa chakawandisa, kabhoni nhema neinonyorovesa zvinogonawo kuwedzerwa muchimiro chepaste. Stearic acid haifanirwe kuwedzerwa nekukurumidza, zviri nyore kukonzera kutenderera, zviri nani kuiwedzera kana paine kabhoni nhema muroro, uye vulcanizing agent inofanirawo kuwedzerwa padanho rinotevera. Mamwe ma vulcanizing agents anowedzerwawo kana paine kabhoni nhema shoma parororo. Semushonga we vulcanizing DCP. Kana kabhoni dema rese rikadyiwa, DCP ichapiswa yonyungudutswa kuita mvura, iyo inowira mutireyi. Nenzira iyi, huwandu hwezvinhu zvinonyungudutsa mukomboni huchaderedzwa. Nekuda kweizvozvo, mhando yekomboni yerabha inokanganiswa, uye inogona kukonzera vulcanization isina kubikwa zvakanaka. Nokudaro, chinhu chinonyungudutsa chinofanira kuwedzerwa panguva yakakodzera, zvichienderana nemhando yacho. Mushure mekunge mhando dzese dzezvinhu zvinonyungudutsa dzawedzerwa, zvinodikanwa kuti utenderedze zvakare kuti komboni yerabha isanganiswe zvakaenzana. Kazhinji, pane "mapanga masere", "mabhegi etriangle", "kumonereka", "matong matete" nedzimwe nzira dzekutenderedza.
"Mapanga masere" kucheka mapanga nekona ye45° nenzira yakafanana yeroller, kana kudivi rimwe nerimwe. Guruu rasara rinomonyororwa 90° rowedzerwa kuroller. Chinangwa ndechekuti rabha rimoneredzwe nenzira dzakatwasuka uye dzakatwasuka, izvo zvinoita kuti pave nekusanganiswa kwakafanana. "Triangle bag" ibhegi repurasitiki rinogadzirwa kuita triangle nesimba reroller. "Kumoneredza" kucheka banga neruoko rumwe, kumoneredza rabha kuita silinda neruoko rumwe, wozoiisa muroller. Chinangwa cheizvi ndechekuita kuti rabha isanganiswe zvakaenzana. Zvisinei, "triangle bag" uye "kumoneredza" hazvibatsiri kupisa kwerabha, izvo zviri nyore kukonzera kupisa, uye zvinoda simba rakawanda, saka nzira idzi mbiri hadzifanirwe kukurudzirwa. Nguva yekutendeuka maminetsi mashanu kusvika matanhatu.
Mushure mekunge rabha yanyungudutswa, zvakakosha kutetepa rabha. Maitiro ekugadzira akaratidza kuti rabha yakabatana inoshanda zvikuru pakupararira kwechinhu chinosanganisa rabha murabha. Nzira yekucheka rabha ndeyekugadzirisa daro reroller kusvika pa 0.1-0.5 mm, kuisa rabha muroller, uye kuirega ichiwira mutireyi yekudyisa zviri pamutemo. Mushure mekunge yadonha, tenderedza rabha ne90° pamusoro peroller. Izvi zvinodzokororwa ka5 kusvika ka6. Kana tembiricha yerabha yakakwira zvakanyanya, mira rabha yakabatana, uye mirira rabha yatonhorera usati watetepa kudzivirira rabha kuti isapise.
Mushure mekunge rabha yapera, bvisa daro remupumburu kusvika pa4-5mm. Rabha isati yaiswa mumota, chidimbu chidiki cherabha chinobviswa choiswa mumaroller. Chinangwa ndechekuburitsa daro remupumburu, kuitira kudzivirira muchina wekusanganisa rabha kuti usapinzwe nesimba guru uye kukuvadza michina mushure mekunge rabha yakawanda yaiswa muroller. Mushure mekunge rabha yaiswa mumota, inofanira kupfuura nepakati pemupumburu kamwe chete, yozoiputira paroller yepamberi, yoramba ichiitenderedza kwemaminitsi maviri kusvika matatu, uye yoisunungura nekuitonhodza nenguva. Firimu racho rakareba 80 cm, 40 cm yakafara uye 0.4 cm yakakora. Nzira dzekutonhodza dzinosanganisira kutonhodza kwechisikigo uye kutonhodza tangi remvura inotonhora, zvichienderana nemamiriro eyuniti yega yega. Panguva imwe chete, zvakakosha kudzivirira kusangana pakati pefirimu nevhu, jecha nedzimwe tsvina, kuitira kuti zvisakanganise mhando yerabha.
Mukuita kwekusanganisa, daro rekutenderera rinofanira kudzorwa zvakasimba. Tembiricha inodiwa pakusanganisa marubha akasiyana-siyana asina kugadzirwa uye kusanganisa mishonga yakasiyana-siyana yekuomarara yakasiyana, saka tembiricha yeroller inofanira kunzwisiswa zvichienderana nemamiriro ezvinhu chaiwo.
Vamwe vashandi vekusanganisa rabha vane pfungwa mbiri dzisiri idzo: 1. Vanofunga kuti kana nguva yekusanganisa yakareba, kunaka kwerabha kwakakwira. Izvi hazvisizvo zvinoitika mukuita, nekuda kwezvikonzero zvatsanangurwa pamusoro apa. 2. Zvinotendwa kuti kana huwandu hweglue hwakaunganidzwa pamusoro peroller hukawedzerwa nekukurumidza, kumhanya kwekusanganisa kuchakurumidza. Kutaura zvazviri, kana pasina guruu rakaungana pakati pemaroller kana guruu rakaungana riri diki zvakanyanya, hupfu huchadzvanywa nyore nyore kuita maflakes uye huwire mutireyi yekudyisa. Nenzira iyi, pamusoro pekukanganisa kunaka kwerabha rakasanganiswa, tireyi yekudyisa inofanira kucheneswa zvakare, uye hupfu hunodonha hunowedzerwa pakati pemaroller, izvo zvinodzokororwa kakawanda, izvo zvinorebesa nguva yekusanganisa uye zvinowedzera simba rekushanda. Ehe, kana kuunganidzwa kweglue kwakanyanya, kumhanya kwekusanganisa kwehupfu kunodzikira. Zvinogona kuonekwa kuti kuunganidzwa kwakawandisa kana kushoma kweglue hakuna kunaka pakusanganisa. Naizvozvo, panofanira kunge paine huwandu hwakati hweglue rakaungana pakati pemaroller panguva yekusanganisa. Panguva yekukanya, kune rumwe rutivi, hupfu hunodzvanywa muglue nesimba remuchina. Nekuda kweizvozvo, nguva yekusanganisa inopfupikiswa, simba rekushanda rinodzikira, uye mhando yerabha inogadzirwa zvakanaka.
