Kwa zaka zambiri, kupanga ma roller a rabara kwapangitsa kuti makina ndi makina opangira makina azivuta chifukwa cha kusakhazikika kwa zinthu komanso kusiyanasiyana kwa kukula kwake.Mpaka pano, ambiri a iwo akadali pamanja-based discontinuous unit ntchito mizere kupanga.Posachedwapa, akatswiri ena akuluakulu opanga zinthu ayamba kuzindikira kupanga kosalekeza kuchokera ku zipangizo za mphira kupita ku njira zowumba ndi zowonongeka, zomwe zachulukitsa kaŵirikaŵiri kupanga bwino komanso kupititsa patsogolo kwambiri malo ogwira ntchito ndi mphamvu zogwirira ntchito.
M'zaka zaposachedwapa, luso jekeseni, extrusion ndi mapiringidzo wakhala mosalekeza anayamba, ndi akamaumba mphira wodzigudubuza ndi vulcanization zipangizo wapanga kupanga mphira wodzigudubuza pang'onopang'ono mechanized ndi basi.Kuchita kwa mphira wodzigudubuza kumakhudza kwambiri makina onse, ndipo kumakhala kovuta kwambiri pakuchita ntchito ndi kupanga khalidwe.Zambiri mwazinthu zake zasankhidwa kukhala zabwino kwambiri.Pakati pawo, kusankha kwa mphira ndi pulasitiki ndi kuwongolera kulondola kwazinthu ndizofunika kwambiri.Pamwamba pa mphira wa rabara saloledwa kukhala ndi zonyansa, matuza ndi thovu, osasiya zipsera, zolakwika, grooves, ming'alu ndi masiponji am'deralo ndi zochitika zosiyana siyana zofewa ndi zovuta.Pachifukwa ichi, wodzigudubuza mphira ayenera kukhala woyera mwamtheradi ndi mosamalitsa ntchito yonse yopanga, kuti azindikire opareshoni ogwirizana ndi standardization luso.The ndondomeko kaphatikizidwe mphira pulasitiki ndi zitsulo pachimake, pasting, jekeseni akamaumba, vulcanization ndi kugaya kotero wakhala mkulu-chatekinoloje ndondomeko.
Kukonzekera kwa mphira
Kwa odzigudubuza mphira, kusakaniza mphira ndiye ulalo wofunikira kwambiri.Pali mitundu yopitilira 10 ya zida za mphira zodzigudubuza kuyambira mphira wachilengedwe ndi mphira wopangira mpaka zida zapadera.Zomwe zili mphira ndi 25% -85%, ndipo kuuma kwake ndi dothi (0-90) madigiri, omwe amayenda mosiyanasiyana.Choncho, momwe mungasakanizire mankhwalawa mofanana ndi vuto lalikulu.Njira yodziwika bwino ndiyo kugwiritsa ntchito mphero yotseguka posakaniza ndi kukonza mu mawonekedwe a magulu osiyanasiyana ambuye.M'zaka zaposachedwa, makampani asintha kwambiri zosakaniza zamkati kuti akonze zopangira mphira pogwiritsa ntchito kusakaniza kwamagulu.
Pambuyo posakaniza mphira, mphira iyenera kusefedwa ndi fyuluta ya rabara kuti ichotse zonyansa muzinthu za rabara.Kenaka gwiritsani ntchito calender, extruder, ndi laminating makina kuti mupange filimu kapena chojambula popanda thovu ndi zonyansa za kupanga mphira wodzigudubuza.Asanapangidwe, mafilimuwa ndi zomatira ziyenera kuyang'aniridwa mosamalitsa kuti achepetse nthawi yoyimitsa magalimoto, kukhalabe ndi malo atsopano komanso kupewa kumamatira ndi kupindika kwa extrusion.Chifukwa chakuti ambiri odzigudubuza mphira ndi zinthu zomwe sizinapangidwe, pakakhala zonyansa ndi thovu pamwamba pa mphira, matuza amatha kuwoneka pamene pamwamba pa nthaka pambuyo pa vulcanization, zomwe zidzachititsa kuti mphira yonseyo ikonzedwe kapena kuchotsedwa.
