Nigute Igipfunyika cya Plastiki gikozwe?

Injira mu gikoni icyo ari cyo cyose cy’ubucuruzi cyangwa mu bubiko bwo kohereza, kandi birashoboka ko uzabona imizingo ya firime ibonerana ikururwa, irambuye, kandi izengurutswe ku bicuruzwa. Gupfunyika plastike ni kimwe mu bikoresho bigaragara cyane mu bikoresho bigezweho no kubungabunga ibiryo. Bituma ibisigisigi byacu bigashya kandi bikerekana ko ibicuruzwa bidacika mugihe cyo gutambuka.

Nuburyo bugaragara bworoshye, tekinoroji iri inyuma yibi bikoresho, birambuye biratangaje. Guhindura pelletike ikomeye muri firime ya micron-yoroheje bisaba kugenzura neza ubushyuhe, ubwubatsi bugezweho, hamwe nubushakashatsi bwihariye. Gusobanukirwa iyi nzira bitanga ubushishozi muburyo ababikora bagera kuri ubwo buringanire bwuzuye bwo kwizirika, kumvikana, n'imbaraga.

Ibikoresho Byibanze: Aho Byose Bitangirira

Urugendo rwumuzingo wa pulasitike rutangira kera mbere yuko imashini zifungura. Bitangirana no guhitamo ibikoresho bibisi. Ibikoresho bisanzwe bikoreshwa kuriyi ntego ni Umurongo muto-Ubucucike bwa Polyethylene (LLDPE).

Iyo abayikora bagamije gukora firime ya PE ipfunyika , bavanga LLDPE ninyongera zihariye. Izi nyongeramusaruro ningirakamaro kuko polyethylene mbisi ntabwo isanzwe yiziritseho. Kurema 'gukomera, ' ababikora bongeramo tackifiers (nka polyisobutylene). Ibindi byongeweho bishobora kubamo kurinda firime urumuri rwa UV cyangwa gukumira ibyubaka.

Mugihe Polyvinyl Chloride (PVC) yahoze ari igipimo cyo gupfunyika ibiryo, PE (Polyethylene) yiganje cyane kubera igiciro cyayo kandi ikoreshwa neza. Gupfunyika pallet yinganda, PE nibintu byonyine byo guhitamo.

Umutima wibikorwa: Inzira yo Gukuramo

Guhinduka kuva pellet kuri firime bibaho imbere a imashini ikora ibikoresho . Mugihe hariho uburyo bubiri bwingenzi bwo gukora firime ya pulasitike - yavuzwe kandi ikorwa - uburyo bwo gukuramo ibicuruzwa ni igipimo cyinganda zo kwihuta cyane, cyiza cyane.

Dore intambwe-ku-ntambwe yo gusenya uburyo umurongo wo gukuramo firime ukora:

1. Kugaburira no gushonga

Inzira itangirira kuri hopper, nini nini ya feri. Uruvange rwa plastike resin pellet ninyongeramusaruro bigaburirwa mumashini. Imbaraga rukuruzi zikurura pellet hasi muri barri ya extruder, ibamo umugozi munini uzunguruka.

Mugihe umugozi uhindutse, usunika pellet imbere. Ubushyuhe bwo hanze hamwe nubuvanganzo buterwa na screw byashongesheje plastike mumazi meza. Iyi ni intambwe ikomeye; niba ubushyuhe budakomeje neza, plastike irashobora kwangirika cyangwa kunanirwa kuvanga neza.

2. Gukabya Binyuze mu Gupfa

Plastike yashongeshejwe ihatirwa gupfa - igufi, itambitse. Ibi bigena ubugari bwambere nubunini bwa firime. zo mu rwego rwo hejuru Imashini zipfunyika zikoresha uburyo bwa 'co-extrusion '. Ibi bivuze ko imashini ikora ibice byinshi bya plastike icyarimwe (akenshi 3, 5, cyangwa 7) hanyuma ikabihuza mumpapuro imwe mugihe basohotse bapfa.

Gushyira hamwe bituma ababikora bakora injeniyeri yihariye. Kurugero, urwego rwimbere rushobora kuba rwongeyeho 'cling ', mugihe urwego rwinyuma rwakozwe kugirango rworoshe kugirango pallet idafatana mugihe cyo kohereza.

3. Gukonjesha no Gukomera

Filime ishyushye imaze gusohoka, igomba guhita ikonjeshwa kugirango ifunge imiterere n'imiterere. Umwenda wa pulasitike ushongeshejwe ugwa kuri 'gukonjesha ' - ingoma nini, ikonjesha amazi.

Umuvuduko umuzingo wa chill uzunguruka ugereranije n'umuvuduko wo gusohora ugena ubunini bwa nyuma bwa firime. Niba umuzingo uzunguruka vuba, plastike irambuye neza. Ubu buryo bwihuse bwo gukonjesha nibyo biha firime ya firime isobanutse neza.

4. Kuzunguruka no kunyerera

Filime ihamye ikururwa binyuze murukurikirane rw'ibizunguruka kugirango igenzure ubunini bwuzuye hamwe nudusembwa. Hanyuma, irakomerekejwe hejuru ya master master (umuzingo wa jumbo). Iyi mizingo akenshi iba nini cyane kubakoresha-nyuma, mubisanzwe rero yimurirwa mumashini yatembye aho yaciwe mubugari buto hanyuma igasubira mubikarito wabonye mububiko.

Abakinnyi na Bavuza: Kugereranya Uburyo bwo Gukora

Mugihe uburyo bwo gukina bwasobanuwe haruguru burazwi cyane kubera umuvuduko no gusobanuka, ababikora bamwe bakoresha uburyo bwa firime. Mugihe cyo gusohora, plastiki irasunikwa hejuru yumuzingi kugirango ibe igicucu, gikonjeshwa numwuka.

Kugufasha gusobanukirwa nuburyo butanga ibisubizo, dore kugereranya ibiranga bisanzwe bifitanye isano na buri bwoko bwimashini:

Ikiranga	Gukuramo	Gukabya
Kugaragara	Nibyiza (Birasobanutse kandi byuzuye)	Hasi (Birashobora kuba ibicucu)
Umuvuduko Wumusaruro	Hejuru	Hasi
Kurira	Nibyiza	Nibyiza (Imbaraga-zerekezo ebyiri)
Urusaku	Hatuje	Kurangurura ijwi
Ubwiza bwa Cling	Uruhande rumwe cyangwa Uruhande rumwe	Mubisanzwe Uruhande rumwe
Gukoresha Rusange	Gupfunyika pallet, Gufunga igikoni	Imifuka yinganda zikomeye, firime yubuhinzi

Udushya mu mashini zipfunyika

Icyifuzo cya firime zoroshye ariko zikomeye nizo zitera udushya mumashini. Imashini igezweho yo gupfunyika plastike ntikiri umushyushya gusa. Nuburyo bwikora cyane bugamije kugabanya imyanda no gukoresha ingufu.

Abakora inganda zikomeye, nka XHDTE, bibanda mugukora imirongo yubwenge, yihuta. Izi mashini zifite ibikoresho byemerera abashoramari kugenzura ubunini bwa firime kugeza kuri micron. Ubu busobanuro ni ngombwa kuko gukoresha plastike nkeya kugirango ugere ku mutwaro umwe uhagaze ni intego y'ibanze ku bucuruzi bwangiza ibidukikije.

Imashini nshya nazo ziranga:

• Guhinduranya byikora: Imashini ikata firime igatangira umuzingo mushya udahagaritse umurongo.

• Gusubiramo ibizunguruka: trim trim (plastike irenze yaciwe kumpande) ihita iramanuka igasubizwa muri extruder, bigatuma imyanda ya zeru mugihe cyo kuyibyaza umusaruro.

• Ikwirakwizwa ryambere: Ubushobozi bwo gushyira inyongeramusaruro zihenze gusa mubice byihariye, kugabanya ibiciro byibintu muri rusange.

Kugenzura Ubuziranenge no Kwipimisha Byanyuma

Mbere yuko firime yoherezwa kubakwirakwiza cyangwa mu nganda, ikorerwa ibizamini bikomeye. Umuzingo wa PE gupfunyika firime irashobora kugaragara nkiyoroshye, ariko igomba gukora mukibazo.

Ikizamini cyo kugenzura ubuziranenge bwa:

• Kurambura: Filime ishobora kurambura kugeza ryari mbere yuko ifata? Gupfunyika imashini nziza cyane birashobora kurambura kugeza 300% cyangwa birenga.

• Kurwanya Kurwanya: Ese inguni zikarishye ku gasanduku zizanyura muri firime?

• Cling Force: Ese firime yihambiriye neza itabanje gukuramo igihe?

Niba firime yananiwe ibizamini, ikibazo gishobora gukurikiranwa nubushyuhe bwubushyuhe kuri extruder cyangwa igipimo cyinyongera zikoreshwa mukuvanga.

Igihe kizaza cyo gutunganya film

Gukora ibipfunyika bya pulasitike ni siyansi yuzuye igereranya chimie nubuhanga. Mugihe inganda zigenda zigana ku buryo burambye, imashini zikoreshwa mugukora ziriya firime ziragenda zihinduka mugutunganya ibikoresho bibora kandi bikongera gukoreshwa neza.

Kubucuruzi bugira uruhare mubikoresho cyangwa gupakira, gusobanukirwa uburyo ibi bikoresho bikozwe byerekana akamaro ko guhitamo film ibereye akazi. Yaba ikomeza sandwich nshya cyangwa ikabika toni y'amatafari kuri pallet, tekinoloji iri inyuma yizinga iremeza ko ifashe neza.
