Gukuramo Filime Niki?

Kuva mumifuka ya pulasitike dukoresha mubiribwa kugeza kuri firime zirinda zituma ibiryo byacu bishya, amabati ya plastike yoroheje ni igice cyingenzi mubuzima bwa none. Umubare munini wibi bikoresho bikozwe muburyo bwo gukora bwitwa firime ya firime.

Aka gatabo gasobanura ishingiro ryubu buhanga bukoreshwa cyane mu nganda. Uzamenya icyo gukuramo firime icyo aricyo, uburyo inzira ikora kuva itangiye kugeza irangiye, ibikoresho birimo, nibisabwa bitandukanye. Mugihe cyanyuma, uzasobanukirwa neza nuburyo pellet yoroshye ya pulasitike ihindurwa muri firime zitandukanye duhura nazo buri munsi.

Gusobanukirwa Gukuramo Filime

Gukuramo firime ni uburyo bukomeza bwo gukora buhindura ibikoresho bya termoplastique, nka polyethylene, muburyo bworoshye bwa firime. Izina riva mubikorwa bibiri byingenzi birimo: 'gukuramo ' plastiki yashongeshejwe binyuze mu rupfu no 'guhuha ' umwuka muri yo kugirango iyagure mubibyimba binini.

Iki gihu noneho kirakonjeshwa, kigwa mumpapuro iringaniye, hanyuma gikomeretsa kumuzingo. Igisubizo ni firime ya plastike ihindagurika cyane ishobora gukoreshwa muburyo butandukanye bwa porogaramu, cyane cyane mu nganda zipakira. Inzira yemerera kugenzura neza ubugari bwa firime, ubugari, nibintu bifatika.

Igikorwa cyo Gukuramo Amashusho: Intambwe ku yindi

Gukora firime ya plastike ukoresheje ubu buryo birimo ibyiciro bitandukanye. Buri ntambwe igenzurwa neza kugirango ibicuruzwa byanyuma byujuje ubuziranenge bwihariye nibisabwa.

Intambwe ya 1: Kugaburira ibikoresho no gushonga

Inzira itangirana nibikoresho bya termoplastique mbisi, mubisanzwe muburyo bwa pellet nto cyangwa granules. Iyi pellet igaburirwa kuva muri hopper muri barrale ya extruder. Imbere muri barriel, umugozi uzunguruka utwara ibikoresho imbere. Iyo pellet zigenda zinyura kuri screw, ziterwa nubushyuhe bukabije buturutse kumashanyarazi ashyushye kuri barriel hamwe no guterana amagambo biterwa no kuzunguruka. Uku guhuza ubushyuhe nigitutu bishonga thermoplastique muburyo bumwe, bwashongeshejwe buzwi nka 'gushonga. '

Intambwe ya 2: Gukuramo binyuze mu rupfu

Iyo plastiki imaze gushonga burundu kandi igahuzwa, umugozi uyisunika mumapaki ya ecran, iyungurura ibintu byose byanduye cyangwa ibice bidashonga. Akayunguruzo gashonga noneho gahatirwa gupfa uruziga. Uru rupfu, akenshi ruciriritse (rumeze nk'impeta), rukora plastiki yashongeshejwe mu rukuta ruto rukikijwe, rudafite umwobo. Igishushanyo cyurupfu ni ingenzi, kuko kigena diameter yambere nuburebure bwurukuta rwigituba cya plastiki.

Intambwe ya 3: Ifaranga no Kuzamuka

Mugihe umuyoboro ushongeshejwe usohoka mu rupfu mu cyerekezo cyo hejuru, umugezi wumwuka uhumeka winjizwa hagati yacyo unyuze mu kirere. Umuvuduko wimbere wimbere utera umuyoboro kwaguka cyane, nkisabune. Iyi nzira yo guta agaciro, izwi nka gusohora firime , kurambura plastike haba muburyo bwa (transvers icyerekezo) no muburyo bwo gusohora (icyerekezo cyimashini). Icyerekezo cya biaxial gitanga firime yongerewe imbaraga nubworoherane.

Ikigereranyo kiri hagati ya diameter ya bubble ya nyuma na diametre ipfa byitwa guturika (BUR). Iri gereranya nikintu cyingenzi kigira ingaruka kumiterere ya firime, harimo imbaraga zayo zingana no kurwanya amarira.

Intambwe ya 4: Gukonjesha

Kugirango ushimangire plastike yagutse kandi ushireho ibipimo byayo, igomba gukonjeshwa vuba kandi kimwe. Ibi mubisanzwe bigerwaho ukoresheje impeta yihuta yumuyaga yashyizwe hejuru yurupfu. Impeta yo mu kirere iyobora umwuka ukonje ugenzurwa hejuru yinyuma. Muburyo bumwe, sisitemu yo gukonjesha imbere (IBC) nayo ikoreshwa mugukonjesha firime imbere, bigatuma igipimo cyumusaruro cyihuse no kugenzura neza. Ingingo polymer ikomera izwi nkumurongo wubukonje.

Intambwe ya 5: Gusenyuka no Kuringaniza

Nyuma yo gukonjesha, ibinini binini, bihamye bikomeza kugenda hejuru, akenshi kuri metero nyinshi, kugeza kumurongo wikadiri cyangwa umunara waguye. Aya makadiri ayobora buhoro buhoro igituba mu muringoti uringaniye, utarinze kugikora. Igituba noneho gikururwa binyuze murukurikirane rwizunguruka, rwitwa nip rollers, rugikanda neza kandi rukirukana umwuka wafatiwe imbere.

Intambwe ya 6: Guhindura firime

Hanyuma, firime iringaniye, igizwe na kabili ikomerekejwe kumuzingo munini. Ukurikije porogaramu igenewe, firime irashobora kuvurwa kumurongo. Kurugero, irashobora kunyura mumiti ya corona kugirango ihindure ingufu zubuso bwayo, bigatuma irushaho kwakira neza wino cyangwa ibifatika. Impande zumuyoboro wa lay-flat zirashobora kandi gutemagurwa kugirango ukore impapuro ebyiri zitandukanye za firime, cyangwa irashobora kubikwa nkumuyoboro wo gukora imifuka.

Ibikoresho Rusange Byakoreshejwe

Amashanyarazi atandukanye ya polimoplastike arashobora gukoreshwa mugusohora firime, ariko ibisanzwe ni polyethylene bitewe nuburyo bwinshi, gukora neza, hamwe nibikorwa byiza biranga.

• Polyethylene nkeya (LDPE): Azwiho guhinduka, gusobanuka, no koroshya, LDPE ikoreshwa cyane mumifuka ya pulasitike, firime zipakira ibiryo, na firime yubuhinzi.

• Polyethylene Yinshi cyane (HDPE): HDPE itanga firime ikomeye, ikomeye, kandi idasobanutse kurusha LDPE. Ifite imiti irwanya imiti kandi ikoreshwa kenshi mumifuka y'ibiribwa, imyanda, hamwe ninganda.

• Umurongo muto-wuzuye Polyethylene (LLDPE): Gutanga impirimbanyi hagati ya LDPE na HDPE, LLDPE itanga imbaraga zingana cyane, kwihanganira gucumita, no guhinduka. Ni amahitamo azwi cyane kuri firime zirambuye, imifuka iremereye, hamwe no gupakira ibiryo.

• Ibindi bikoresho: Izindi polymers nka Polypropilene (PP), Ethylene-Vinyl Acetate (EVA), na Polyamide (PA) nazo zikoreshwa mubisabwa bisaba ibintu byihariye nko gusobanuka neza, gufunga ubushyuhe, cyangwa ubushobozi bwa bariyeri.

Imirongo ya firime igezweho akenshi irashobora gufatanya gusohora, aho extruders nyinshi igaburira ibikoresho bitandukanye mugupfa rimwe kugirango ikore firime yibice byinshi. Ibi bituma ababikora bahuza imiterere ya polymers zitandukanye muburyo bumwe, nko gukora firime hamwe na ogisijeni ya barrière yo gupakira ibiryo.

Porogaramu ninyungu

Filime yakozwe binyuze muri firime ya firime iragaragara hose mubikorwa byo gupakira no hanze yacyo. Bimwe mubikorwa byibanze birimo:

• Gupakira Abaguzi: Guhaha imifuka, kubyara imifuka, imifuka yimigati, hamwe nugupakira ibiryo bikonje.

• Gupakira mu nganda: Kurambura ibicuruzwa byo guhunika ibicuruzwa, kugabanya gupfunyika ibicuruzwa, hamwe n’imifuka iremereye cyane kubikoresho nkubutaka cyangwa ifumbire.

• Filime yubuhinzi: Igifuniko cya Greenhouse, firime ya mulch, hamwe na silage bifasha kuzamura umusaruro wibihingwa no kurinda umusaruro.

• Filime yubwubatsi: Inzitizi zumuyaga hamwe nimpapuro zo gukingira zikoreshwa ahubatswe.

• Filime yamurika: Filime zikoreshwa nkibice murwego rworoshye rwo gupakira ibintu.

Ibyiza byingenzi byiyi nzira harimo ubushobozi bwayo bwo gukora umuyoboro utagira ikidodo, icyerekezo cyiza cya biaxial cyerekanwe kumikoreshereze yubukanishi, hamwe nubushobozi buhanitse bwo gutumiza ibicuruzwa byinshi.

Igihe kizaza cyo gutunganya film

Gukuramo firime ni tekinoroji ikuze ariko ikomeza gutera imbere. Inzira ikomeje kuba ingenzi mu gukora firime yoroheje ya plastike ningirakamaro mu gupakira, ubuhinzi, n’izindi nganda zitabarika. Mugusobanukirwa uburyo pelletike mbisi zahinduwe muri firime ikora, turashobora gushima neza injeniyeri ijya mubicuruzwa bya buri munsi twishingikirije. Mugihe ibyifuzo byibikoresho biramba hamwe nubushobozi buke bipfunyika bigenda byiyongera, guhanga udushya muriki gice bizakomeza gushiraho ejo hazaza h’inganda.
