Kusanganiswa kwerabha kuparadzira akasiyana makomisheni zvakaenzana murabha nerubatsiro rwemakanika simba ekugadzira rabha muchina, kuitira kuti igadzire multi-phase colloidal dispersion system ine rabha sepakati kana musanganiswa werabha uye zvimwe zvinhu zvinoenderana (matching agent, mamwe mapolymers) sepakati, uye asingaenderane matching agents (senge, etc. process. Izvo zvinodiwa zvehunyanzvi zvekugadzirisa maitiro ndeizvi: kupararira kweyunifomu yeanosanganisa agent, kuitira kuti kupararira kwakanakisa kweanosanganisa agent, kunyanya iyo yekusimbisa inosanganisa agent yakadai secarbon dema, inowanikwa kuti ive nechokwadi chekushanda kwerabha. Rabha rinozobuda rinonzi 'compounding rabha' uye kunaka kwaro kune simba rakakosha pakuenderera mberi nekugadzirisa uye kunaka kwechigadzirwa.
1 - Kusanganiswa kwe neoprene
Neoprene ndiyo emulsion polymerization nzira yekugadzira, maitiro ekugadzira anonyanya kuve ega kettle intermittent polymerization. Kupisa kwepolymerization kunonyanya kudzorwa pa40-60 ℃, uye chiyero chekushandura chinenge 90%. Polymerization tembiricha, mwero wekupedzisira wekushandura wakanyanya kana polymerization process mumhepo inotungamira mukudzikira kwemhando yechigadzirwa. Iyo yakaenzana molecular mass inodzorwa nesarufa-kiuram (tetraalkylmethylaminothiocarbonyldisulfide) system mukugadzira. Iko kusakosha kukuru kwe sulfur-kiuram system ndeyekushaya kugadzikana kwezvisungo zvesarufa, iyo ndeimwe yezvikonzero zvakakosha zvekuchengetedza zvinhu. Kana iyo yakaenzana molecular mass yakagadziriswa ne thiol inogona kuvandudza kushanda uku. Neoprene yakasiyana kubva kune general synthetic rubber, haishandisi sulfur vulcanization, asi ne zinc oxide, magnesium oxide, nezvimwewo.
Kugadziriswa kwekuita kweneoprene kunoenderana nehunhu hwe viscoelastic hwerabha isina kuvhurika, uye hunhu hwayo hwe viscoelastic hune hukama neyakasiyana neoprene uye tembiricha. Sezvo kusanganiswa kunowanzoitwa mune elastic state kushandisa simba rekugera reya elastic mamiriro erabha kuita kuti filler ipararire zvakanaka. Naizvozvo, kudzivirira pesvedzero yekushisa kwepamusoro paunenge uchisanganisa neoprene, iyo filler inofanirwa kuwedzerwa nekukurumidza sezvinobvira kuitira kuti iwane imwe dhigirii yekusanganisa mune elastic state. Kana uchisanganiswa neyakavhurika refiner, G-mhando neoprene inonzwa nekushanduka kwetembiricha, uye tembiricha ye roll inodarika 70 ℃, inonamira zvakanyanya, uye iri muviscous kuyerera, uye iyo filler haisi nyore kuparadzira. Kana uchisanganiswa ne dense refiner, huwandu hwayo hunofanira kudzikiswa zvakafanira, iyo general filling factor ye 0.6 yakakodzera, inowanzo patsanurwa kuita maviri musanganiswa, kuitira kuderedza tembiricha yekusanganisa. Tembiricha yekuburitsa inofanira kunge yakaderera pane 100 ℃.
Neoprene mukushandiswa kweyakavhurika muchina kusanganisa kusakanganiswa ndiko kupisa kwakakura, nyore kunamatira kune ma roller, nyore kupisa, neagent dispersion inononoka, saka tembiricha yekusanganisa haifanire kunge yakanyanya kukwirira, huwandu hunofanira kunge hudiki, iyo roller yekumhanyisa ratio haifanirwe kunge yakakura. Nekuda kwekunzwa kwakasimba kune tembiricha, general-chinangwa neoprene pakamuri tembiricha kusvika 71 ℃, icharatidza mamiriro ezviyo, panguva ino kubatana kwerabha mbishi kunopera simba, kwete chete zvakakomba zvinonamira rollers, pamwe neajenti kupararira kuchave kwakaomawo. Iyo elastic state tembiricha yeasina-sarufa-inodzorwa neoprene iri pazasi 79 ℃, saka kusanganisa maitiro kuita kuri nani pane kudzorwa nesarufa, uye katsika kekunamira rollers uye kupisa idiki. Kukanya nemuchina wakashama, kuitira kudzivirira ma roller anonamira, tembiricha yemupumburu inowanzodzorwa pa40 ~ 50 ℃ kana pasi (iyo yekumberi iri 5 ~ 10 ℃ yakaderera pane yekumashure tembiricha yekumashure), uye mukukanya rabha mbishi, kureba kunofanirwa kugadziridzwa zvishoma nezvishoma kubva kuhombe kuenda kudiki. Pakusanganisa, tanga wawedzera acid inonyudza magnesium oxide kudzivirira kupisa, uye pakupedzisira wowedzera zinc oxide. Kuti uderedze kupisa kwekusanganiswa, kabhoni dema uye mvura inopfavisa inogona kuwedzerwa mumabhechi neimwe nzira. Stearic asidhi neparafini wakisi uye zvimwe zvinobatsira zvekushandisa zvinogona kuparadzirwa zvishoma nezvishoma zvichiwedzerwa, kuitira kubatsira kupararira, asiwo kudzivirira zvinonamira rollers. Sulfur-regulated chloroprene rabha munguva yekuvhura yekusanganisa inowanzorebesa 30% kusvika 50% kureba kupfuura yerudzi rubber, isiri-sarufa-inodzorwa-inodzorwa kusanganisa nguva inogona kuita ipfupi 20% pane inodzorwa nesarufa. Kuti udzivise neoprene mumushini wekusanganisa mukuvhurwa kwekushisa kukwira nekukurumidza, chiyero chekumhanya chiri pasi pe1: 1.2 pazasi, kutonhora kunenge kuri nani. Kuderedza kugona kwekunatsa zvakare inzira yekuvimbisa kuchengetedzwa kwekushanda uye kupararira kwakanaka. Parizvino, sarufa-inodzorwa neoprene rabha refinesa simba pane yakasikwa rabha inofanira kunge iri pasi pe20% kusvika 30%, kuitira kuti ishande zvakajairika. Sezvo neoprene iri nyore kupisa, saka mukushandisa dense yekunatsa muchina musanganiswa unowanzo shandiswa munzira mbiri dzekusanganisa. Tembiricha yekusanganisa inofanirwa kunge yakadzikira (tembiricha yekuburitsa kazhinji inodzorwa pasi pe100 ℃), simba rekurodha rakaderera pane iro rerabha rechisikigo (capacity factor inowanzotorwa se 0.50 ~ 0.55), uye zinc oxide inowedzerwa kumapepanhau muchikamu chechipiri chekusanganisa. Nekuda kwedambudziko rekuti chloroprene rabha kusanganiswa kuri nyore kupisa uye kunetsa kuparadzira, Leena refiner anotora yakanyanya kumberi mana-ring double rotor ichimhanya munzira imwe chete, yakasanganiswa ne 'X' curve yekufamba kwebhaudhi repamusoro painatsiridza, ine yakanaka dispersion effect uye nguva pfupi, iyo inogona kunyatso kudzikisa kupisa kunopisa kwe chlorop kusanganisa muitiro we chlorop kusanganisa.
2 - Kusanganiswa kwe ethylene propylene rubber
Ethylene propylene rabha inogonawo kugadziriswa neyakajairwa rabha yekunatsa michina, asi nekuti iyo plasticizing mhedzisiro ye ethylene propylene rabha inonyanya kushata, kushomeka kweviscosity, rabha haisi nyore kuputira mupumburu, kazhinji kutanga kushandisa yakatetepa roll pitch, kugadzira pepa rinoenderera uyezve kuwedzera roll gomba rekusanganisa kugadzirisa. Roll tembiricha yekumberi roll 50 ~ 60 ℃, mushure mekupumburudza 60 ~ 70 ℃ yakakodzera. EPDM rubber feeding order inowanzonzi: raw raw cover roll-1/2 carbon black-1/2 carbon black-stearic acid-zinc oxide (kana magnesium oxide) -promoter-crosslinker -Thin pass, pasi peshizha. Ethylene propylene rabha haisi nyore pamusoro-yakanatswa kana ichisanganiswa, uye komboni yacho inoparadzirwa zvakaenzana, asi iyo yekuzvinamira pfuma haina kunaka. Ethylene-propylene rabha inosanganiswa neyakavhurika refiner, kazhinji tanga shandisa diki roll nguva kuti ienderere mberi mushure memupumburu, wozozorora zvishoma nezvishoma nguva yekukungurusa, wedzera komputa, tembiricha yemupumburu iri pakati pe60 ~ 70 ℃. Iyo tembiricha yekusanganisa ndeye 150～160 ℃, iyo inogona kubatsira kupararira kwekuzadza uye kupfava uye kuvandudzwa kwezvinhu zvemuchina. Kurodha simba kunogona kuva 10% ~ 15% yakakwirira kupfuura zvimwe zvigadzirwa zverabha.
3- Kusanganiswa kwefluoroelastomer
Fluorine rubber Menny viscosity yakakwira, yakasimba, inokakavadzana kupisa chizvarwa, kusanganisa kwakawanda uye kugadzirisa kwakanyanya kuoma. Kana uchisanganisa fluorine rabha pamushini wekuchenesa, kusvika kudiki roll chinhambwe, kushoma kugona, roll tembiricha kutonga pa50 ~ 60 ℃. Kusanganisa kunotanga, kutanga kuita kuti rollers itonhore, wedzera raw rabha yakaonda kupfuura kanenge ka10 kuti iite yunifomu yepasuru mupumburu rabha, gadzirisa mupumburu nguva kuchengetedza shoma shoma rabha akaturikidzana, uye wobva wawedzera komponeng mumiririri, kusanganisa nguva kazhinji haana kunyatsotsanangurwa, asi zvinoda nokukurumidza sezvinobvira. Fluorine rabha yakanyanya kuoma kushandisa musanganiswa muchina kusanganisa, asi iyo meshing mhando yemuchina wekusanganisa kutonhora system yakasimba, unogona kusanganisa fluorine rabha. Iyo yakasanganiswa rabha inofanirwa kumisa kwemaawa makumi maviri nemana isati yashandiswa, uye inofanirwa kunatswa isati yashandiswa kuita kuti komisheni ipararire zvakaenzana uye kuvandudza kuyerera uye kuzvinamira kwerabha.
