Mfundo yogwiritsira ntchito makina opangira jekeseni ndi chiyani.

Mfundo yogwiritsira ntchito makina opangira jakisoni ndi ofanana ndi a syringe ya jakisoni.Ndi njira yobaya pulasitiki yosungunula ya pulasitiki (ie viscous flow) mubowo lotsekedwa ndi nkhungu mothandizidwa ndi kuponyera kwa wononga (kapena plunger), ndikupeza mankhwalawo atachiritsidwa ndi kupanga.

Kupanga jekeseni ndi njira yozungulira, kuzungulira kulikonse kumaphatikizapo: kudyetsa kochulukira - kusungunuka ndi pulasitiki - jekeseni wamagetsi - kudzaza nkhungu ndi kuzizira - kutsegula nkhungu ndi kutenga mbali.Mukatulutsa gawo la pulasitiki, tsekaninso nkhungu kwa mkombero wotsatira.

Makina opangira jakisoni: Zinthu zamakina omangira jekeseni zimaphatikizira kuwongolera kiyibodi, magwiridwe antchito amagetsi ndi ma hydraulic system.Sankhani kachitidwe ka jekeseni, kudyetsa, kuthamanga kwa jekeseni, kuthamanga kwa jekeseni ndi mtundu wa ejection, kuyang'anira kutentha kwa gawo lililonse la mbiya, ndikusintha kuthamanga kwa jekeseni ndi kukakamiza kumbuyo.

Njira yopangira makina opangira jekeseni wamba ndi: choyamba, onjezerani granular kapena powdery pulasitiki mu mbiya, ndikupangitsa pulasitiki kusungunuka kupyolera mu kuzungulira kwa wononga ndi kutentha kwa khoma lakunja la mbiya, ndiye makinawo amatseka nkhungu. ndikuyendetsa mpando wa jekeseni kutsogolo kuti mphuno ikhale pafupi ndi chipata cha nkhungu, ndiyeno jekeseni mafuta opanikizika mu silinda ya jekeseni kuti akankhire wononga patsogolo, motero, zinthu zosungunuka zimalowetsedwa mu nkhungu yotsekedwa ndi kutentha kochepa pamtunda wapamwamba. kuthamanga ndi kuthamanga.Pakapita nthawi ndikukonza kupanikizika (komwe kumadziwikanso kuti kukakamiza) ndikuzizira, nkhungu imatha kutsegulidwa ndipo chinthucho chimatha kutulutsidwa (cholinga cha kukakamiza ndikuletsa kusuntha kwazinthu zosungunuka mu nkhungu, zowonjezera. zipangizo ku nkhungu patsekeke, ndi kuonetsetsa kuti mankhwala ali ndi kachulukidwe ndi dimensional kulolerana).Zofunikira pakuumba jekeseni ndi pulasitiki, jekeseni ndi kuumba.Plasticization ndiye maziko ozindikira ndikuwonetsetsa kuti zinthu zowumbidwa zili bwino.Kuti akwaniritse zofunikira pakuumba, jekeseni iyenera kuonetsetsa kuti kuthamanga ndi kuthamanga kokwanira.Nthawi yomweyo, chifukwa cha kuthamanga kwambiri kwa jekeseni, kupanikizika kwakukulu kumapangidwa mu nkhungu (kuthamanga kwapakati pa nkhungu nthawi zambiri kumakhala pakati pa 20 ~ 45MPa), kotero payenera kukhala mphamvu yokwanira yoletsa.Zitha kuwoneka kuti chipangizo chojambulira ndi chipangizo cholumikizira ndizinthu zazikulu zamakina opangira jakisoni.
