Isi idukikije yuzuyemo ibicuruzwa bya pulasitiki, kuva mubipfunyika bituma ibiryo byacu bishya kugeza kumiyoboro itanga amazi meza murugo rwacu. Byinshi muribi bintu bya buri munsi byakozwe muburyo bwo gukora bwitwa extrusion, kandi intandaro yiki gikorwa ni imashini ikuramo.
Kumva uburyo izo mashini zikora ni urufunguzo rwo gushima ubwubatsi inyuma yibicuruzwa bitabarika dukoresha buri munsi. Aka gatabo kazasobanura imashini yo gukuramo icyo aricyo, uburyo bwo gusohora bukora, ubwoko butandukanye bwimashini ziboneka, hamwe nibisanzwe bikoreshwa mubikorwa bitandukanye. Waba uri umunyeshuri, wifuza injeniyeri, cyangwa ufite amatsiko gusa yo gukora, iyi nyandiko izatanga ishusho rusange yubu buhanga bwingenzi.
Muri rusange, gukuramo ni inzira aho ibikoresho fatizo bisunikwa mu rupfu kugirango habeho ikintu gifite imiterere yihariye, ikomeza kwambukiranya ibice. Tekereza gukuramo amenyo yinyo mu muyoboro - gufungura umuyoboro ni ugupfa, kandi umuti wamenyo usohoka muburyo burebure, buhoraho.
An imashini yo gukuramo ikora kandi inonosora iki gitekerezo cyo gukora inganda. Inzira itangirana nibikoresho bya pulasitiki mbisi, mubisanzwe muburyo bwa pellet nto cyangwa granules. Ibi bikoresho bigaburirwa muri mashini, aho bishonga, bivanze, kandi bigahatirwa gupfa muburyo bwihariye kugirango bibe umwirondoro uhoraho. Uyu mwirondoro noneho urakonjeshwa hanyuma ukatirwa kuburebure bwifuzwa. Igicuruzwa cyanyuma gishobora kuba ikintu cyose kuva umuyoboro woroheje cyangwa umuyoboro kugeza kumadirishya igoye cyangwa firime yoroheje.
Igikorwa cyibanze cyimashini isohora ni ukugenzura neza ubushyuhe, umuvuduko, n'umuvuduko kugirango ibicuruzwa byanyuma byujuje ibisobanuro byuzuye kubuziranenge no guhoraho.
Mugihe ibishushanyo bishobora gutandukana, imashini nyinshi zo gusohora zisangira ibice byingenzi bikora hamwe kugirango bihindure plastike mbisi mubicuruzwa byarangiye.
Inzira itangirira kuri hopper, ikintu kinini, gifite ishusho ya feri ifata pelletike mbisi. Uhereye kuri hopper, ibikoresho bigaburirwa muri barrile ku gipimo cyagenwe. Guhuza iyi funguro ningirakamaro kugirango ibicuruzwa byanyuma bifite ubuziranenge bumwe.
Barrale nicyumba kirekire, cya silindrike kibamo umugozi munini uzunguruka. Aha niho ubumaji bubera. Mugihe screw izunguruka, ikora imirimo itatu ikomeye:
1.Gutwara ibicuruzwa: Yimura pelleti ya plastike kuva kumuhogo wo kugaburira munsi yuburebure.
2.Gushonga: Akabari kazengurutswe nibintu bishyushya bishonga plastiki. Ubuvanganzo n'umuvuduko ukomoka ku kuzunguruka na byo bigira uruhare runini mu bushyuhe, inzira izwi nko gushyushya ubwoya.
3.Uvangavanga: Imashini ihuza plastike yashongeshejwe, ikemeza ko ifite ubushyuhe buhoraho hamwe nibigize. Inyongeramusaruro hamwe namabara birashobora kandi kuvangwa muriki cyiciro.
Gupfa nigikoresho cyabugenewe kidasanzwe gitanga ibikoresho byakuwe muburyo bwa nyuma. Ifatanye kumpera ya barriel, kandi plastiki yashongeshejwe irahatirwa kuyinyuramo munsi yumuvuduko mwinshi. Gupfa byakozwe mugukora umwirondoro wihariye, uhereye kumiterere yoroshye izengurutse imiyoboro kugeza kumiterere igoye cyane kubice byabigenewe. Mu gukora firime ya pulasitike, imashini ikuramo firime ikoresha imashini ipfuye kugirango itange urupapuro ruto kandi rugari.
Iyo plastiki yashongeshejwe imaze kuva mu rupfu, igomba gukonjeshwa no gukomera mugihe ikomeza imiterere yayo. Ibi mubisanzwe bikorwa mukunyura mu bwogero bwamazi cyangwa ukayobora umwuka mwiza kuri yo. Ibikoresho bingana, nka Calibibator ya vacuum, akenshi bikoreshwa mugufasha gufata umwirondoro mubipimo nyabyo uko bikonje.
Imashini, izwi kandi nk'ikinyabiziga gikurura, ifata ibicuruzwa byakonje hanyuma ikayikura mu rupfu ku muvuduko uhoraho. Umuvuduko wa puller uhujwe neza nigipimo cyo gukuramo kugirango ugenzure ubunini nubunini bwibicuruzwa. Hanyuma, gukata - nk'icyuma cyangwa icyuma - gabanya umwirondoro uhoraho muburebure bwateganijwe.
Imashini za Extrusion zashyizwe mubyiciro byinshi bitewe nigishushanyo cyazo, bigira ingaruka kuburyo butaziguye.
Ubu ni ubwoko busanzwe kandi bworoshye bwa imashini . Iranga umugozi umwe uzunguruka muri barriel. Extruders imwe imwe yizewe, ihendutse, kandi nibyiza mugutunganya ibintu byinshi bya polymers. Zikoreshwa cyane mugukora imiyoboro, igituba, impapuro, na profil.
Nkuko izina ribigaragaza, izo mashini zikoresha imigozi ibiri yo kuzunguruka izunguruka muri barriel. Twin-screw extruders itanga ubushobozi buhebuje bwo kuvanga no guhuza, bigatuma biba byiza mubisabwa bisaba kuvanga polymers zitandukanye, kongeramo ibyuzuza, cyangwa gushyiramo amabara. Bakunze gukoreshwa mugukora plastike ikora cyane hamwe nibintu byihariye.
Hariho ubwoko bubiri bwibanze bwa twin-screw extruders:
· Kuzunguruka: Imiyoboro yombi ihinduka icyerekezo kimwe, itanga ibikorwa byiza byo kuvanga.
· Guhinduranya-guhinduranya: Imiyoboro ihindukirira mu cyerekezo gitandukanye, ikora imbaraga zo kogosha zikwiranye no gutunganya ibikoresho byangiza ubushyuhe nka PVC.
Imashini ikuramo firime ni ubwoko bwihariye bwa extruder yagenewe gukora firime nziza ya plastike nziza. Muri ubu buryo, polymer yashongeshejwe isohoka mu rupfu ruringaniye kuri roller ikonje, isennye cyane. Gukonjesha byihuse gushimangira plastike mumpapuro ifite ubwumvikane buhebuje, ubunini bumwe, hamwe nubuso bworoshye. Izi mashini ningirakamaro mugukora firime zipakira, gupfunyika plastike, nibindi bicuruzwa byoroshye.
Ikoranabuhanga rya Extrusion riratandukanye cyane, hamwe nibikorwa bikoresha inganda nyinshi. Dore bimwe mubicuruzwa bisanzwe bikozwe hakoreshejwe imashini zo gukuramo:
· Imiyoboro hamwe nigituba: Kuva imiyoboro ya PVC kugeza kubuvuzi bworoshye.
· Imyirondoro: Ikadiri yidirishya, amakadiri yumuryango, kashe, hamwe nimitako.
· Urupapuro na firime: Urupapuro rwa plastiki rwo gupakira, gupfunyika ibiryo, na firime yubuhinzi. Imashini ikuramo firime ikoreshwa cyane cyane muribi bikorwa.
· Gufata insinga ninsinga: Gukingira insinga zamashanyarazi ninsinga.
· Filaments: Gukora filaments zo gucapa 3D.
· Guteranya: Kuvanga ibisigazwa bya pulasitike hamwe ninyongera kugirango ukore ibintu byabigenewe.
Imashini ya Extrusion ningirakamaro mubikorwa bigezweho, ituma umusaruro unoze, mwinshi mwinshi wibicuruzwa bya plastiki bitabarika bigize ubuzima bwacu bwa buri munsi. Kuva mubishushanyo byoroheje bya extruder imwe kugeza kubushobozi bugoye bwa sisitemu ya twin-screw, izi mashini zakozwe muburyo bwuzuye kandi bwizewe. Ibikoresho byihariye nka imashini ikuramo firime ikomeza kwagura ibishoboka, yemerera gukora firime zo murwego rwohejuru zikenewe mugupakira nibindi.
Uko ikoranabuhanga rigenda ritera imbere hamwe n’ibisabwa ku bikoresho birambye kandi bikora neza, urwego rwo gukuramo ruzakomeza gutera imbere. Udushya mu gushushanya imashini, kugenzura ibikorwa, hamwe na siyanse y'ibikoresho bizemeza ko imashini ikuramo ikomeza kuba igikoresho cy'ingirakamaro ku bakora mu myaka iri imbere.
