Niba urebye hafi y'urugo cyangwa aho ukorera, birashoboka ko uzabona ibintu byinshi byakozwe ukoresheje inzira yitwa extrusion. Kuva mu miyoboro ya PVC mu rukuta rwawe kugeza kuri firime ya pulasitike ipfunyika ibiryo byawe, imashini zisohora ni inzu zicecekera inyuma y'ibicuruzwa bitabarika bya buri munsi. Ariko mubyukuri imashini ikuramo ni iki, kandi ikora ite?
Gusobanukirwa nubusobanuro bwimashini ya extrusion ikubiyemo ibirenze kumenya ibisobanuro byayo. Birasaba kureba mubukanishi, ibikoresho byakoreshejwe, hamwe nurwego runini rwa porogaramu ikorana buhanga. Mu gukora, imashini isohora imbaraga ihatira ibikoresho binyuze mu rupfu rufite ishusho yo gukora ibintu bikomeza hamwe nu mwirondoro uhamye. Iyi nzira ningirakamaro mu nganda kuva ubwubatsi n’imodoka kugeza gutunganya ibiryo no gupakira.
Aka gatabo kazasenya ubukanishi bwo gusohora, gucukumbura ubwoko butandukanye bwimashini-harimo na firime yihariye yo kurambura-kandi ikagaragaza impamvu iryo koranabuhanga rikomeza kuba umusingi w’inganda zigezweho.
Muri rusange, an imashini ikuramo ni igikoresho gikoreshwa mu gushonga no gutunganya ibikoresho fatizo - mubisanzwe plastiki cyangwa ibyuma - muburyo bukomeza. Ihame ryibanze risa no gukuramo amenyo yinyo mu muyoboro. Umuvuduko ukoreshwa uhatira paste (ibikoresho) unyuze kumuzingo (gupfa), bikavamo ishusho ndende, ya silindrike.
Mu nganda, inzira iragoye cyane kandi neza. Ibikoresho bibisi, akenshi muburyo bwa pellet cyangwa granules, bigaburirwa muri barri yimashini. imbere, umugozi uzunguruka utanga ubushyamirane n'ubushyuhe, gushonga ibikoresho. Iyo bimaze gushongeshwa, ibikoresho bisunikwa mu rupfu rurangije ingunguru, bikabigira muburyo bwifuzwa. Ibi birashobora kuba umuyoboro, urupapuro, firime, cyangwa umwirondoro utoroshye kumadirishya.
Inyungu nyamukuru yo gukoresha imashini ikuramo ni ubushobozi bwayo bwo gukora ibintu byinshi bifite ireme hamwe nubunini. Kuberako inzira ikomeza, irakora neza kandi ihendutse kubyara umusaruro.
Kugirango usobanukirwe neza ibisobanuro byimashini ikuramo, ifasha gusobanukirwa intambwe-ku-ntambwe iboneka imbere mu bikoresho. Mugihe hariho itandukaniro bitewe nibikoresho nibirangira, uburyo rusange bugumaho.
Inzira itangirira kuri hopper, ikintu kimeze nka funnel aho hasukwa ibikoresho bya termoplastique mbisi (resin). Ibisigarira akenshi biza muburyo bwa pellet kandi birashobora kuvangwa ninyongeramusaruro nkamabara cyangwa UV inhibitor mbere yo kwinjira mumashini.
Uhereye kuri hopper, uburemere bugaburira pellet muri barriel. Imbere muri barrale haryamye umugozi muremure, uzunguruka. Mugihe umugozi uhindutse, wimura ibikoresho imbere. Ubuvanganzo bwa mashini bwakozwe na screw, bufatanije nubushyuhe bwo hanze buzengurutse ingunguru, bishonga pelletike ya plastike mumazi meza.
Mbere yuko plastiki yashongeshejwe igera ku rupfu, mubisanzwe inyura muri ecran ya ecran. Iyi nteko iyungurura umwanda kandi ifasha kubaka umuvuduko winyuma muri barriel, ituma gushonga ari kimwe kandi nta mwuka uhumeka.
Nibihe bikomeye aho imiterere yihariye yashizweho. Plastike yashongeshejwe ihatirwa gupfa, ikora nk'ishusho ya nyuma. Igishushanyo mbonera cyo gupfa cyerekana niba ibisohoka ari urupapuro ruringaniye, umuyoboro wuzuye, cyangwa firime yoroheje.
Iyo ibikoresho bimaze kuva mu rupfu, biracyashyushye kandi birashoboka. Igomba gukonjeshwa vuba kugirango igumane imiterere yayo. Ibi mubisanzwe bigerwaho ukoresheje ubwogero bwamazi, imizingo ikonjesha, cyangwa ibyuma byo mu kirere. Nyuma yo gukonjesha, ibicuruzwa bikomeza bigabanywa muburebure bwihariye cyangwa igikomere kuri spol.
Ikoranabuhanga rya Extrusion riratandukanye, kandi imashini zitandukanye zakozwe mubikorwa byihariye. Mugihe extruder imwe imwe isanzwe, izindi zitandukanye zirahari kugirango zikemure ibikoresho nibicuruzwa bigoye.
Izi ninganda zinganda zo gutunganya plastiki rusange. Biroroshye cyane, birahenze, kandi byiza cyane gushonga no kuvoma polymers. Zikoreshwa cyane mugukora imiyoboro, impapuro, na profil.
Nkuko izina ribigaragaza, izo mashini zikoresha imigozi ibiri ihuza. Twin-screw extruders itanga ubushobozi bwiza bwo kuvanga, bigatuma biba byiza kubikoresho byo guhuza, gutunganya polymers-yubushyuhe, cyangwa gukorana nibisabwa bisaba urwego rwinshi rwuzuza ninyongera.
Iyi mikorere yihariye ikora firime ya plastike. Plastike yashongeshejwe isohoka mu buryo buhagaritse binyuze mu ruziga ruzengurutse, ikora umuyoboro. Umwuka uhita uhuhira hagati yigituba, ukawuzunguza nka ballon kuri diameter yifuzwa nubunini. Nuburyo bwibanze bwo gukora imifuka yo guhaha na firime yubuhinzi.
Icyiciro cyihariye kandi cyingenzi cya imashini zo gukuramo ni firime irambuye. Izi mashini zabugenewe muburyo bwo gukora firime yoroheje, yoroheje ya pulasitike ikoreshwa mu gupfunyika pallets hamwe nibicuruzwa bifite umutekano byoherezwa.
Kurambura firime ya extruder mubisanzwe ikoresha inzira ya firime. Polimeri yashongeshejwe isohoka mu rupfu rushyizwe hejuru. Gukonjesha byihuse gushimangira firime ako kanya, byemeza neza n'imbaraga. Isohora rya firime irambuye akenshi ikoresha ibice byinshi - rimwe na rimwe bigera kuri 50 cyangwa birenga micro-layer - kugirango ikore firime zoroshye cyane ariko zidashobora kwihanganira. Iyi mikorere igabanya imikoreshereze yibikoresho mugihe ikomeza umutwaro uremereye, ikintu gikomeye kubigo bitanga ibikoresho bigamije kugabanya ibiciro n imyanda.
Akamaro ka mashini yo gukuramo irenze kure ibice byoroshye bya plastiki. Ubushobozi bwayo bwo gutunganya ibikoresho bitandukanye bituma biba ingenzi mumirenge myinshi.
Inganda zubaka zishingiye cyane cyane ku gukuramo ibicuruzwa. Imiyoboro ya PVC yo kuvoma, vinyl side kumazu, hamwe nibiranga idirishya ryimyirondoro nibintu byose muriki gikorwa. Kuramba no guhangana nikirere cya plastiki zasohotse bituma bakora uburyo bwiza bwibiti nicyuma.
Nibishobora kugaragara cyane. Kuva kumpapuro zuzuye zuzuye mububiko kugeza kuri firime irambuye ibika pallets mububiko, gusohora ni hose. Kurambura firime ndende, byumwihariko, bigira uruhare runini murwego rwo gutanga amasoko ku isi, bigatuma ibicuruzwa bigera aho bijya neza.
Gukuramo ntibigarukira gusa kuri plastiki. Mu nganda z’ibiribwa, imashini zisohora zikoreshwa mu gukora amakariso, ibinyampeke bya mu gitondo, ibiryo, n’ibiryo by’amatungo. Inzira iteka kandi ikora icyarimwe icyarimwe, itanga uburyo bwo gukora imiterere nuburyo bukurura abakiriya.
Ibinyabiziga bigezweho birimo ibice byinshi byasohotse, harimo kashe yumuryango, insinga, hamwe numurongo wa lisansi. Imiterere yoroheje ya plastiki yakuweho ifasha kuzamura imikorere ya peteroli bitabangamiye umutekano cyangwa imikorere.
Ubusobanuro bwimashini ikuramo irenze ibisobanuro byayo; byerekana imikorere no guhanga udushya mubikorwa. Izi mashini zemerera ibigo kugabanya imyanda mugutunganya ibikoresho bishaje bigasubira mubikorwa. Bashoboza kurema ibintu bigoye, byubatswe byinshi bihuza imiterere ya polymers zitandukanye-nko kongeramo inzitizi kubipfunyika byokurya kugirango ubuzima bwiyongere.
Byongeye kandi, iterambere mu ikoranabuhanga rituma izo mashini zirusha ubwenge. Ibicuruzwa bigezweho bigizwe na sensor na software ikurikirana umuvuduko, ubushyuhe, nibisohoka mugihe nyacyo, ihindura ibipimo byikora kugirango ireme neza. Uru rwego rwo kwikora rugabanya igihe cyo gukoresha no gukoresha ingufu, bigatuma inzira yo gukora iramba.
Mugihe inganda zitezimbere uburyo burambye kandi bunoze bwo gukora, imashini ikuramo ikomeje gutera imbere. Turimo kubona impinduka yerekeza kumashini zishobora gutunganya plastiki ibinyabuzima hamwe nijanisha ryibintu byongeye gukoreshwa.
Kurambura firime extruder nayo iratera imbere, hamwe nababikora batezimbere ikoranabuhanga kugirango bakore firime zoroheje zikomeza gukora cyane. Iyi 'kumanura ' igabanya ingano ya plastike ikenerwa kuri buri mutwaro, ikemura ibibazo by’ibidukikije bijyanye n’imyanda ya plastiki.
Gusobanukirwa imashini ya extrusion irumva inkingi yo gutunganya ibikoresho bigezweho. Yaba kurinda ibiryo byawe, gutwara amazi murugo rwawe, cyangwa gushaka imizigo y'urugendo rwambukiranya igihugu, ibicuruzwa byakozwe nizi mashini nibyingenzi mubuzima bwacu bwa buri munsi. Mugihe ikoranabuhanga rigenda ritera imbere, turashobora kwitega ko ibikorwa byo gukuramo bizarushaho kuba byiza, bikoresha ingufu, kandi bitangiza ibidukikije.
