Nigute Imashini ya Extrusion ikora?

Mwisi yisi yinganda zigezweho, gukuramo ni inzira yifatizo, ningirakamaro mugukora ibicuruzwa byinshi, uhereye kumiyoboro ya pulasitike no kumadirishya yidirishya kugeza kubipfunyika bikomeye birinda ibiryo byacu. Intandaro yiki gikorwa ni imashini ikuramo , igitangaza cyubwubatsi buhindura ibikoresho bibisi muburyo bukomeza kandi neza. Iyi ngingo izasesengura amahame shingiro yukuntu imashini ikuramo ikora, hibandwa cyane cyane kumurongo wohanze wa Film .

Ihame ryibanze ryo gukabya

Muburyo bworoshye cyane, gukuramo ni inzira yo gukora ibintu uyihatira gufungura byateguwe, byitwa gupfa. Bitekerezeho nk'uruganda rukomeye rwo gukinisha rukinisha: usunika ibintu byoroshye ukoresheje ifumbire imeze, kandi umurongo muremure, uhoraho hamwe nuburyo bwihariye ugaragara kurundi ruhande. Mu nganda, ibikoresho mubisanzwe ni polimoplastique polymer muburyo bwa pellet, granules, cyangwa ifu.

Ibyingenzi byingenzi bigize imashini ikuramo

An imashini ikuramo , cyangwa extruder, ntabwo igikoresho kimwe ahubwo sisitemu ihuriweho. Ibice byingenzi byingenzi bikora hamwe kugirango bishonge, bahuze, kandi bakora plastike. Dore gusenyuka:

1. Hopper: Inzira itangirira hano. Ibikoresho bya pulasitiki bibisi bigaburirwa muri hopper, ikora nk'ikigega, ihora itanga ingunguru ya extruder.

2. Barrale na Screw: Numutima wimashini ikuramo . Barrale ni silinderi ishyushye, ikomeye irimo imashini izunguruka neza. Imashini ifite zone eshatu zingenzi:

• Ahantu ho kugaburira: Iki gice cyakira pellet zikomeye ziva muri hopper hanyuma kikabageza imbere.

• Agace ko guhunika (gushonga): Hano, uburebure bwindege ya screw buragabanuka, bikanda plastike. Ufatanije nubushyuhe bwo hanze kuri barriel hamwe no gutemagura gukabije kuva kwizunguruka rya screw, plastike irashonga mumazi amwe.

• Agace k'ibipimo: Igice cya nyuma kirimo ubujyakuzimu, guhora mu ndege bitera umuvuduko ukabije kandi bikomeza guhuza, guhuza ibinyabuzima bya pulasitike yashongeshejwe mu rupfu. Ibi nibyingenzi kubicuruzwa byanyuma.

3. Ubushuhe hamwe na sisitemu yo gukonjesha: Ubushyuhe bwa bande buzengurutse ingunguru butanga ingufu zikenewe zumuriro kugirango ushonge polymer. Abafana bakonje birinda sisitemu gushyuha bitewe nubushyuhe bukabije butangwa na screw.

4. Gupfa: Gupfa nigikoresho cyabigenewe gitanga plastiki yakuwe muburyo bwa nyuma. Yaba uruziga rworoshye kumuyoboro cyangwa ahantu hakeye hagaragara firime, igishushanyo cyo gupfa nikintu cyambere. Plastike yashongeshejwe ihatirwa muri uku gufungura, ifata ishusho yayo.

5. Haul-Off (Puller) na Sisitemu yo gukonjesha: Nyuma yo kuva mu rupfu, ishusho ya plastike ishyushye, yoroshye igomba gukonjeshwa no gukomera, mubisanzwe ukoresheje ubwogero bwamazi cyangwa impeta zikonjesha ikirere. Igice gikurura, akenshi kigizwe na caterpillar tracks, gikurura buhoro buhoro umwirondoro ukonje ku muvuduko ugenzurwa, ukareba ibipimo bihoraho kandi ukirinda guhinduka.

Urubanza rwihariye: Umurongo wo gukuramo firime

Iyo intego ari ugukora amabati ya plastike yoroheje cyangwa firime (nk'imifuka yo guhaha cyangwa gupakira ibiryo), kabuhariwe Umurongo wo gukuramo firime urakoreshwa. Sisitemu yubakiye kuri extruder isanzwe ariko ikubiyemo ibice byingenzi byingenzi kugirango ikemure imiterere yoroheje ya firime. Hariho uburyo bubiri bwibanze:

• Gukuramo Filime: Plastike yashongeshejwe isohoka hejuru ikoresheje uruziga ruzengurutse, ikora umuyoboro muto. Umwuka uhuhwa rwagati muri uyu muyoboro, ukawuzunguza nka ballon mu bubyimba. Uku kurambura kunanura firime no guhuza iminyururu ya polymer, kuzamura imbaraga. Igituba noneho gisenyuka kubayobora no gukomeretsa kumuzingo.

• Gukuramo Filime Gukuramo: Plastike yashongeshejwe isohoka mu igorofa, umurongo upfa guhita ugana ku rinini runini, rukonje. Uku gukonjesha byihuse gukora firime isobanutse neza kandi neza. Ihita ikosorwa kandi igakomereka.

Umurongo usanzwe wa Firime Extrusion Line ihuza extruder nibi bice byo hepfo:

• Extruder: Gushonga no kuvoma polymer.

• Gupfa cyangwa kuzenguruka bipfa: Bikora imiterere yambere ya firime.

• Sisitemu yo gukonjesha (Impeta zo mu kirere cyangwa Chill Rolls): Ikomeza firime.

• Ubunini bwa Gauging: Gukurikirana no kwemeza ubunini bwa firime.

• Ubuvuzi bwa Surface (Corona Treater): Ihindura ubuso bwa firime kugirango wongere neza wino cyangwa icapwe.

• Winder: Kuzamura firime yarangiye muminini minini kugirango ihindurwe.

Kugereranya Uburyo bwo Gukuramo Filime

Imbonerahamwe ikurikira iragaragaza itandukaniro ryibanze hagati yuburyo bubiri bukuru bwa Firime Yerekana :

Ibiranga	Filime Yerekana Filime Gukuramo	Filime
Ubwoko bwo gupfa	Kuzenguruka	Flat (Ahantu)
Icyerekezo cya Extrusion	Mubisanzwe	Mubisanzwe
Uburyo bukonje	Impeta zo mu kirere	Gukonjesha
Ibyiza bya Filime	Imbaraga Zirenze, Zisobanutse neza	Ubwiza buhebuje, Uburinganire bwa Gauge
Icyerekezo cya molekulari	Bi-axial Icyerekezo (ikomezwa mubyerekezo byombi)	Icyambere Mono-axial Icyerekezo
Ibisanzwe	Amashashi yo guhaha, Filime irambuye, Filime yubuhinzi	Gupakira ibiryo, Laminations, Firime Yamafoto

Umwanzuro

Imashini yo gukuramo ni gihamya yubuhanga bwinganda, ihindura plastike mbisi muburyo butagira ingano bwimiterere yingirakamaro. Kuva kumwirondoro woroshye kugeza kuri tekinoroji yo hejuru Firime Extrusion Line itanga firime ziboneka mubuzima bwa kijyambere, iyi nzira ningirakamaro kwisi yacu yakozwe. Mugusobanukirwa ubufatanye hagati ya hopper, ingunguru, screw, no gupfa, hamwe nibikoresho byabugenewe byo hepfo, turashobora gushima neza no kugenzura bisabwa kugirango dukore ibicuruzwa bihoraho, byujuje ubuziranenge twishingikiriza buri munsi.
