Okutabula kapiira kwe kusaasaanya ebirungo eby’enjawulo kyenkanyi mu kapiira nga tuyambibwako amaanyi ag’ebyuma ag’ekyuma ekikola kapiira, okusobola okukola enkola y’okusaasaanya ebipiira mu mitendera mingi nga kapiira nga wakati oba omutabula gwa kapiira n’ebitundu ebimu ebikwatagana (ekirungo ekikwatagana, ebiwujjo ebirala) nga ebya wakati, n’ebintu ebikwatagana ebitakwatagana (nga ebijjuza pawuda, zinki okisayidi, . langi, n’ebirala) nga ekitundu ekisaasaanyiziddwa. omutendero. Ebyetaago ebitongole eby’ekikugu eby’enkola y’okugatta bye bino: okusaasaana mu ngeri y’emu okw’ekirungo ekigatta, olwo okusaasaanya okusinga obulungi okw’ekirungo ekigatta naddala ekirungo ekinyweza nga kaboni omuddugavu, ne kutuukirizibwa okukakasa nti kapiira kakola bulungi. Omupiira oguvaamu guyitibwa 'compounding rubber' era omutindo gwagwo gulina kinene kye gukola ku kwongera okulongoosa n'omutindo gw'ebintu.

1 - Okugatta ebirungo bya neoprene

        Neoprene ze nkola ya emulsion polymerization ey’okufulumya, enkola y’okufulumya esinga kuba ya single kettle intermittent polymerization. Ebbugumu lya polymerization lisinga kufugibwa ku 40-60 °C, era omutindo gw’okukyusa guli nga 90%. Ebbugumu ly’okukola polimeeri, omuwendo gw’okukyusa ogusembayo guli waggulu nnyo oba enkola ya polimeeri mu mpewo ejja kuleeta okukendeera kw’omutindo gw’ebintu. Ekizito kya molekyu ekituufu kifugibwa enkola ya salufa-kiuram (tetraalkylmethylaminothiocarbonyldisulfide) mu kukola. Ekizibu ekikulu ekiri mu nkola ya salufa-kiuram kwe butabeera nnywevu mu biyungo bya salufa, nga eno y’emu ku nsonga enkulu eziviirako eby’obugagga by’okutereka. Singa obuzito bwa molekyu obukwatagana butereezebwa ne thiol kiyinza okulongoosa omulimu guno. Neoprene ya njawulo ku kapiira aka bulijjo, takozesa sulfur vulcanization, wabula ne zinc oxide, magnesium oxide, n’ebirala vulcanization.

Enkola y’okulongoosa neoprene esinziira ku nneeyisa ya viscoelastic eya kapiira akatali ka vulcanized, era enneeyisa yaayo eya viscoelastic ekwatagana n’enjawulo ya neoprene n’ebbugumu. Nga okutabula okutwalira awamu bwe kukolebwa mu mbeera ya laasitiki okukozesa empalirizo y’okusala ey’embeera ya laasitiki ya kapiira okufuula ekijjuza okusaasaana obulungi. N’olwekyo, okwewala okukwatibwako kw’ebbugumu eringi nga otabula neoprene, ekijjuza kisaana okugattibwako nga bukyali okusobola okutuuka ku ddaala eritali limu ery’okutabula mu mbeera ya laasitiki. Bw’otabula n’ekirongoosa ekiggule, neoprene ow’ekika kya G awulira enkyukakyuka mu bbugumu, era ebbugumu ly’omuzingo lisukka 70 °C, lijja kuba mizingo egy’amaanyi ennyo, era eri mu mbeera y’okukulukuta okunywevu, era ekijjuza si kyangu kusaasaanya. Nga otabula n’ekirongoosa ekinene, obusobozi bwakyo bulina okukendeezebwa mu ngeri esaanidde, ensonga y’okujjuza eya bulijjo eya 0.6 esaanidde, okutwalira awamu egabanyizibwamu okutabula kubiri, okusobola okukendeeza ku bbugumu ly’okutabula. Ebbugumu ly’okufulumya lirina okuba wansi wa 100 °C.

Neoprene mu kukozesa ekyuma ekiggule okutabula obuzibu kiri nti ebbugumu ddene, kyangu okunywerera ku rollers, kyangu okuyokya, nga agent okusaasaana kugenda mpola, kale ebbugumu ly’okutabula terina kuba waggulu nnyo, obusobozi bulina kuba butono, roller speed ratio tesaana kuba munene. Olw’obuwulize obw’amaanyi eri ebbugumu, neoprene ow’ekigendererwa eky’enjawulo ku bbugumu erya bulijjo okutuuka ku 71 °C, ejja kulaga embeera y’empeke, mu kiseera kino okukwatagana kwa kapiira embisi kunafuwa, si rollers sticky zokka ez’amaanyi, n’okusaasaana kw’ekirungo nakyo kijja kuba kizibu nnyo. Ebbugumu ly’embeera ya elasitiki eya neoprene etali ya salufa liri wansi wa 79 °C, kale omulimu gw’enkola y’okutabula gusinga okulung’amibwa ekibiriiti, era omuze gw’ebizingulula ebikwatagana n’okwokya mutono. Okufumba n’ekyuma ekiggule, okusobola okwewala ebizingulula ebikwatagana, okutwalira awamu ebbugumu ly’omuzingo lifugibwa ku 40 ~ 50 °C oba wansi (omuzingo ogw’omu maaso guli wansi 5 ~ 10 °C okusinga ebbugumu ly’omuzingo ogw’emabega), era mu kufumba kwa kapiira embisi, ebanga ly’omuzingo lirina okutereezebwa mpolampola okuva ku kinene okudda ku kitono. Bw’oba ​​otabula, sooka oteekemu magnesium oxide anywa asidi okuziyiza okwokya, n’oluvannyuma oteekemu zinc oxide. Okusobola okukendeeza ku bbugumu ly’okutabula, ebigonza bya kaboni omuddugavu n’eby’amazzi bisobola okugattibwa mu bitundutundu nga bikyukakyuka. Stearic acid ne paraffin wax n’ebintu ebirala ebiyamba mu kukola bisobola okusaasaanyizibwa mpolampola nga byongerwako, okusobola okuyamba okusaasaana, naye era okuziyiza ebiwujjo ebikwatagana. Omupiira gwa chloroprene ogufugibwa ekibiriiti mu budde bw’okutabula ekiggulawo okutwalira awamu guwanvuwa ebitundu 30% ku 50% okusinga kapiira ak’obutonde, obudde bw’okutabula obutafugibwa salufa buyinza okuba obumpi ebitundu nga 20% okusinga obulung’amya ekibiriiti. Okusobola okwewala neoprene mu kyuma ekitabula mu kuggulawo ebbugumu lirinnya mangu nnyo, omugerageranyo gw’embiro guli wansi wa 1:1.2 wansi, ekikolwa ky’okunyogoza kijja kuba kirungi. Okukendeeza ku busobozi bw’okulongoosa nakyo ngeri ya kulaba ng’obukuumi mu mirimu n’okusaasaana okulungi. Mu kiseera kino, obusobozi bw’okulongoosa emipiira gya neoprene egy’awaka egy’ekibiriiti okusinga emipiira egy’obutonde bulina okuba wansi wa bitundu 20% ku 30%, okusobola okukola mu ngeri eya bulijjo. Nga neoprene bw’ali ennyangu okuyokya, bwe kityo mu kukozesa ekyuma ekirongoosa ekinene okutabula kutera okukozesebwa mu nkola y’okutabula bbiri. Ebbugumu ly’okutabula lirina okuba wansi (ebbugumu ly’okufulumya okutwalira awamu lifugibwa wansi wa 100 °C), obusobozi bw’okutikka buba wansi okusinga obwa kapiira ak’obutonde (okutwalira awamu ensonga y’obusobozi etwalibwa nga 0.50 ~ 0.55), era zinki okisayidi ayongerwa mu kyuma ekikuba ebitabo mu kitundu eky’okubiri eky’okutabula. Olw'ekizibu nti okutabula kapiira ka chloroprene kyangu okuyokya era kizibu okusaasaanya, Leena refiner yeettanira enkola ey'omulembe esinga okubeera ey'omulembe ey'empeta nnya double rotor eddukira mu kkubo lye limu, nga egattibwa wamu n'entambula ya 'X' curve eya bolt ey'okungulu ku refiner, n'ekikolwa ekirungi eky'okusaasaanya n'obudde obutono, ekiyinza okukendeeza obulungi ekintu eky'okwokya kwa chloroprene rubber mu nkola y'okutabula.

2 - Okugatta ebipiira bya ethylene propylene

       Ethylene propylene rubber era esobola okulongoosebwa n’ebyuma ebya bulijjo ebirongoosa kapiira, naye olw’okuba ekikolwa kya pulasitiika ekya ethylene propylene rubber kibi nnyo naddala, obutaba na viscosity, rubber si kyangu kuzinga roll, okutwalira awamu sooka okozese roll pitch enfunda, okukola sheet egenda mu maaso n’oluvannyuma n’ogaziya roll pitch for mixing processing. Ebbugumu ly’omuzingo ku muzingo ogw’omu maaso 50 ~ 60 °C, oluvannyuma lw’omuzingo 60 ~ 70 °C kisaanidde. EPDM rubber feeding order okutwalira awamu eri: raw rubber cover roll-1/2 carbon black-1/2 carbon black-stearic acid-zinc oxide (oba magnesium oxide)-promoter-crosslinker -Okuyita okugonvu, olupapula olwa wansi. Omupiira gwa Ethylene propylene si mwangu kulongoosebwa nnyo nga gutabuddwa, era ekirungo kino kisaasaanyizibwa kyenkanyi, naye eky’okwesiiga si kibi. Ethylene-propylene rubber okutabula n’ekirongoosa ekiggule, okutwalira awamu sooka okozese akaseera akatono ak’omuzingo okugifuula egenda mu maaso oluvannyuma lw’omuzingo, n’oluvannyuma mpolampola owummuze ekiseera ky’omuzingo, osseemu ekirungo, ebbugumu ly’omuzingo wakati wa 60 ~ 70 °C. Ebbugumu ly’okutabula liri 150～160 °C, ekiyinza okuyamba okusaasaanya ekijjuza n’ekigonza n’okulongoosa eby’ebyuma. Obusobozi bw'okutikka buyinza okuba 10% ~ 15% waggulu okusinga ebintu ebirala ebya kapiira.

3- Okugatta ebirungo bya fluoroelastomer

      Fluorine rubber Menny viscosity eri waggulu, ekaluba, ekola ebbugumu mu kusikagana, okutabula n’okulongoosa okwa bulijjo kizibu nnyo. Nga otabula fluorine rubber ku kyuma ekirongoosa, okutuuka ku roll distance entono, obusobozi obutono, roll temperature control ku 50 ~ 60 °C. Okutabula kutandika, sooka okole ebizingulula ebinyogoga, osseemu kapiira embisi thin pass emirundi nga 10 okukola uniform package roll rubber, otereeze roll moment okukuuma akapiira akatono aka stacked, n’oluvannyuma osseeko compounding agent, obudde bw’okutabula tebutera kutegeerekeka bulungi, naye kyetaagisa amangu nga bwe kisoboka. Fluorine rubber kizibu okukozesa ekyuma ekitabula okutabula, naye ekika kya meshing eky’ekyuma ekitabula cooling system kya maanyi, osobola okutabula fluorine rubber. Omupiira ogukoleddwa mu kirungo gulina okusimbibwa okumala essaawa 24 nga tonnaba kugukozesa, era gulina okulongoosebwa nga tonnaba kugukozesa okusobola okufuula ekirungo okusaasaana kyenkanyi n’okulongoosa amazzi n’okwenyweza kwa kapiira.
