Okutabula kwa kapiira kwe kusaasaanya ebirungo eby’enjawulo kyenkanyi mu kapiira nga tuyambibwako amaanyi ag’ebyuma ag’ekyuma ekikola omupiira, okusobola okukola enkola y’okusaasaana kwa colloidal ey’emitendera mingi ng’erina kapiira nga akapiira aka wakati oba akatabuddwamu akapiira n’ebitundu ebimu ebikwatagana (ekintu ekikwatagana, polimeeri endala) nga medium, n’ebitakwatagana ebikwatagana (nga ebijjukizo bya pawuda, zincokisayidi, pigmenti, ekitangaala ekitaliimu. omutendero. Ebyetaago ebitongole eby’ekikugu eby’enkola y’okugatta bye bino: okusaasaana okw’enjawulo okw’ekirungo ekigatta, bwe kityo okusaasaana okusinga obulungi okw’ekirungo ekigatta, naddala ekirungo ekinyweza nga kaboni omuddugavu, kituukibwako okukakasa nti omupiira gukola bulungi. Omupiira oguvaamu guyitibwa 'compounding rubber' era omutindo gwagwo gulina kinene kye gukola ku kwongera okulongoosa n'omutindo gw'ebintu.

1 - Okuzimba ekirungo kya neoprene .

        Neoprene ye emulsion polymerization enkola y’okukola, enkola y’okukola esinga kuba single kettle intermittent polymerization. Ebbugumu ly’okukola polimeeri lisinga kufugibwa ku 40-60 °C, era omuwendo gw’okukyusa guli nga 90%. Ebbugumu ly’okukola polimeeri, omuwendo gw’okukyusa ogusembayo guli waggulu nnyo oba enkola ya polimeeri mu mpewo ejja kuleetera omutindo gw’ebintu okukendeera. Ekizito kya molekyu ekikwatagana kifugibwa enkola ya sulfur-kiuram (tetraalkylmethylaminothiocarbonyldisulfide) mu kukola. Ekizibu ekikulu eky’enkola ya sulfur-kiuram kwe kubulwa obutebenkevu bwa sulfur bonds, nga eno y’emu ku nsonga enkulu eziviirako okutereka eby’obugagga. Singa molekyu ya molekyu ekwatagana etereezebwa ne thiol esobola okulongoosa omulimu guno. Neoprene ya njawulo ku kapiira akakolebwa mu ngeri ey’enjawulo, tekozesa sulfur vulcanization, wabula ne zinc oxide, magnesium oxide, etc. vulcanization.

Enkola y’okukola ku neoprene esinziira ku nneeyisa ya viscoelastic eya unvulcanized rubber, era enneeyisa yaayo eya viscoelastic ekwatagana n’enjawulo ya neoprene n’ebbugumu. Nga okutabula okutwalira awamu kukolebwa mu mbeera ya elastic okukozesa amaanyi g’okusala ag’embeera ya laasitiki ya kapiira okufuula ekijjuza okusaasaana obulungi. N’olwekyo, okwewala okufuga ebbugumu eringi nga otabula neoprene, ekijjuza kisaana okugattibwako nga bukyali nga bwe kisoboka okusobola okutuuka ku ddaala erimu ery’okutabula mu mbeera ya elastic. Bw’otabula n’ekyuma ekilongoosa enzigule, neoprene ey’ekika kya G etegeera enkyukakyuka mu bbugumu, ate ebbugumu ly’omuzingo lisukka 70 °C, lijja kuba mizingo gya maanyi egy’okukwata, era nga liri mu mbeera y’okukulukuta okw’obuzito, era ekijjuza si kyangu kusaasaana. Bw’otabula n’ekyuma ekirongoosa ekinene, obusobozi bwakyo bulina okukendeezebwa mu ngeri esaanidde, ensonga y’okujjuza ey’awamu eya 0.6 esaanidde, okutwalira awamu egabanyiziddwamu okutabula emirundi ebiri, okusobola okukendeeza ku bbugumu ly’okutabula. Ebbugumu ly’okufulumya lirina okuba wansi wa 100 °C.

Neoprene Mu nkozesa y’okutabula kw’ebyuma ebiggule kwe kuba nti ebbugumu linene, lyangu okunywerera ku bizingulula, nga kyangu okuyokya, ng’okusaasaana kw’ekirungo kibeera mpola, kale ebbugumu ly’okutabula teririna kuba ddene nnyo, obusobozi bulina okuba obutono, omugerageranyo gw’embiro z’ebizingulula tegulina kuba munene. Olw’obuwulize obw’amaanyi eri ebbugumu, neoprene ey’ekigendererwa eky’awamu ku bbugumu erya bulijjo okutuuka ku 71 °C, ejja kulaga embeera y’empeke, mu kiseera kino okukwatagana kwa kapiira akabisi kunafuwa, si kwa maanyi kwokka okukwata ebizimbulukusa, n’okusaasaana kw’ekirungo nakyo kijja kuba kizibu nnyo. Ebbugumu ly’embeera y’obutafaali (elastic state temperature) erya neoprene eritali lya sulfur eri wansi wa 79 °C, kale omulimu gw’okutabula gusinga sulfur-regulated, era omuze gwa sticky rollers n’okwokya mutono. Okufumbisa n’ekyuma ekiggule, okusobola okwewala ebizingulula ebikwatagana, ebbugumu ly’omuzingo okutwalira awamu lifugibwa ku 40 ~ 50 °C oba wansi (omuzingo ogw’omu maaso guba 5 ~ 10 °C wansi okusinga ebbugumu ly’omuzingo ogw’emabega), era mu kufumbira kwa kapiira akabisi, ebanga ly’omuzingo lirina okutereezebwa mpolampola okuva ku nnene okudda ku ntono. Bw’oba ​​otabula, sooka osseeko asidi anywa ekirungo kya magnesium oxide okuziyiza okubuguma, n’okusembayo oteekemu zinki okisayidi. Okusobola okukendeeza ku bbugumu ly’okutabula, ebigonza ebiddugavu n’amazzi bisobola okugattibwa mu bitundutundu nga bikyukakyuka. Stearic acid ne paraffin wax n’ebintu ebirala ebikozesebwa mu kukola bisobola okusaasaanyizibwa mpolampola, okusobola okuyamba okusaasaana, naye era n’okuziyiza ebiwujjo ebinyirira. Omupiira gwa chloroprene ogulung’amibwa sulphur mu budde bw’okutabula oguggulawo okutwalira awamu guwanvu ebitundu 30% ku 50% okusinga omupiira ogw’obutonde, obudde bw’okutabula obutaluŋŋamizibwa sulfur buyinza okuba obumpi nga 20% okusinga obulung’amya sulfur. Okusobola okwewala neoprene mu kyuma ekitabula mu kugguka kw’ebbugumu okulinnya amangu ennyo, omugerageranyo gw’embiro guba wansi wa 1:1.2 wansi, ekikolwa eky’okunyogoza kijja kuba kirungi. Okukendeeza ku busobozi bw’okulongoosa nakyo ngeri ya kukakasa bukuumi mu nkola n’okusaasaana obulungi. Mu kiseera kino, obusobozi bw’okulongoosa obupiira bwa neoprene obulung’amya ekibiriiti mu maka okusinga omupiira ogw’obutonde gulina okuba wansi wa bitundu 20% ku 30%, okusobola okukola mu ngeri eya bulijjo. Engeri Neoprene gy’eyanguwa okuyokya, kale mu kukozesa okutabula kw’ekyuma ekirongoosa ekinene kutera kukozesebwa mu nkola bbiri ez’okutabula. Ebbugumu ly’okutabula lirina okuba wansi (okutwalira awamu ebbugumu ly’okufuuwa lifugirwa wansi wa 100 °C), obusobozi bw’okutikka buba wansi okusinga obwa kapiira ak’obutonde (okutwalira awamu ensonga y’obusobozi bw’obusobozi (capacity factor). Ku kizibu nti okutabula kwa chloroprene rubber kwangu okwokya era okuzibu okusaasaanya, Leena Refiner yeettanira empeta nnya ez’empeta nnya ezitambula nga zidduka mu kkubo lye limu, nga ligatta wamu n’entambula ya 'X' curve ey’ekisumuluzo eky’okungulu ku kirongoosa, n’ekikolwa ekirungi eky’okusaasaana n’ekiseera ekitono, ekiyinza okukendeeza obulungi enkula y’enkukutu ya chloroprene mu nkola ya chloroprene.

2 - Okugatta kwa ethylene propylene rubber .

       Ethylene propylene rubber era esobola okukolebwa n’ebyuma bya bulijjo ebirongoosa emipiira, naye olw’okuba obuveera bw’okukola kwa ethylene propylene rubber naddala bubi, obutaba na viscosity, omupiira si kyangu kuzingako roll, okutwalira awamu sooka okozese roll pitch enfunda, okukola ekipande ekigenda mu maaso n’oluvannyuma okugaziya roll pitch okutabula okulongoosa. Ebbugumu ly’okuyiringisibwa ku muzingo gw’omu maaso 50 ~ 60 °C, oluvannyuma lw’omuzingo 60 ~ 70 °C okusaanidde. EPDM rubber feeding order is Okutwalira awamu: Ekibikka kya kapiira ekibisi Roll-1/2 Carbon Black-1/2 Carbon Black-Stearic Acid-Zinc Oxide (oba Magnesium Oxide)-Promoter-CrossLinker -Eyitamu, empapula eza wansi. Ethylene propylene rubber si kyangu kulongoosa over-refine nga otabula, era ekirungo kino kisaasaanidde kyenkanyi, naye eky’obugagga ekyesiiga kibi. Ethylene-propylene rubber mixing with an open refiler, okutwalira awamu sooka okozese akaseera akatono ak’okuzingulula okugufuula obutasalako oluvannyuma lw’okuzingulula, n’oluvannyuma mpolampola okuwummuza ekiseera ky’okuyiringisibwa, ssaako ekirungo, ebbugumu ly’omuzingo wakati wa 60 ~ 70 °C. Ebbugumu ly’okutabula liri 150～160 °C, ekiyinza okuyamba okusaasaana kw’ekijjuza n’okugonza n’okulongoosa eby’obutonde eby’ebyuma. Obusobozi bw'okutikka buyinza okuba 10%~15% waggulu okusinga ebintu ebirala ebya kapiira.

3- okugatta kwa fluoroelastomer .

      Fluorine Rubber Menny Viscosity eri waggulu, nkalu, okusikagana okw’okusikagana, okutabula n’okulongoosa mu bulambalamba kizibu nnyo. Nga otabula omupiira gwa fluorine ku kyuma ekirongoosa, okutuuka ku bbanga ettono ery’okuzingulula, obusobozi obutono, okufuga ebbugumu ly’okuyiringisibwa ku 50 ~ 60 °C. Okutabula kutandika, sooka okole ebizingulula ebinyogovu, oteekemu akapiira akabisi akagonvu emirundi nga 10 okukola omupiira gwa package roll ogufaanana, okutereeza ekiseera ky’okuzingulula okukuuma akapiira akatono akasimbiddwa, n’oluvannyuma osseeko ekirungo ekigatta, obudde bw’okutabula ebiseera ebisinga tebunnyonnyolwa mu ngeri enkakali, naye byetaaga amangu nga bwe kisoboka. Fluorine rubber kizibu nnyo okukozesa ekyuma ekitabula okutabula, naye ekika kya meshing eky’enkola y’okuyonja ekyuma ekitabula kisingako amaanyi, osobola okutabula fluorine rubber. Omupiira ogugatta gulina okusimbibwa okumala essaawa 24 nga tegunnakozesebwa, era gulina okulongoosebwa nga tegunnakozesebwa okusaasaanya ekirungo kino kyenkanyi n’okulongoosa amazzi n’okwekwata kwa kapiira.
