1. Ibisobanuro bya PE Stretch Film
Filimi yo gupfunyika ya PE (izwi kandi nka stretch wrap) ni filime ya pulasitiki ifite ubushobozi bwo kwifata ishobora kurambura no gupfunyika neza ibicuruzwa, haba ku ruhande rumwe (extrusion) cyangwa ku mpande zombi (humyowe). Kole ntifata ku buso bw'ibicuruzwa ahubwo iguma ku buso bwa filime. Ntisaba kugabanya ubushyuhe mu gihe cyo gupfunyika, bifasha kuzigama ingufu, kugabanya ikiguzi cyo gupfunyika, koroshya gutwara amakontena, no kunoza imikorere y'ibikoresho. Guhuza amapaleti n'amaforoko bigabanya ikiguzi cyo gutwara, kandi gukorera mu mucyo mwinshi byoroshya kumenya ibicuruzwa, bigagabanya amakosa yo kubikwirakwiza.
Ibisobanuro: Ubugari bwa filime y'imashini 500mm, ubugari bwa filime ikoreshwa n'intoki 300mm, 350mm, 450mm, 500mm, ubugari 15um-50um, bushobora gucibwamo ibipimo bitandukanye.
2. Gushyira mu byiciro imikorere ya PE Stretch Film
(1)Filime yo kugorora intoki:Ubu buryo bukoresha cyane cyane gupfunyika intoki, kandi agapira koroshye gakoreshwa n'intoki muri rusange gasaba ubuziranenge buke. Buri gapira gapima ibiro 4 cyangwa 5 kugira ngo byorohe gukoresha.
(2)Filime yo kudoda imashini:Filimi yoroshye gukoresha imashini ikoreshwa mu gupfunyika ibintu, ahanini iterwa no kugenda kw'ibicuruzwa kugira ngo bipfunyike. Isaba imbaraga nyinshi zo gukurura no kwaguka kwa firime.
Igipimo rusange cyo gukamura ni 300%, naho uburemere bw'umuzingo ni 15kg.
(3)Filime yo gukoresha imashini mbere yo kuyitunganya:Ubwo bwoko bwa firime yo gupfunyika ikoreshwa cyane cyane mu gupfunyika mu buryo bwa mekanike. Mu gihe cyo gupfunyika, imashini ipfunyika ibanza kurambura firime ku gipimo runaka hanyuma ikayizunguriza ku bicuruzwa bigomba gupfunyika. Ishingiye ku bunararibonye bwa firime kugira ngo ipfunyike neza. Igicuruzwa gifite imbaraga nyinshi zo gupfunyika, uburebure, no kudapfunyika neza.
(4)Filime y'amabara:Amafilimi y'amabara agaragara mu bururu, umutuku, umuhondo, icyatsi n'umukara. Abakora bayakoresha mu gupakira ibicuruzwa mu gihe batandukanya ibicuruzwa bitandukanye, bigatuma byoroha kumenya ibicuruzwa.
3. Kugenzura uburyo PE Stretch Film ifatana
Gufata neza bituma ibice by'inyuma bya firime yo gupfunyika bifatanya, bigatanga uburinzi ku bicuruzwa kandi bigashyiraho urwego rwo hejuru rurinda ibicuruzwa. Ibi bifasha kwirinda ivumbi, amavuta, ubushuhe, amazi, n'ubujura. Icy'ingenzi ni uko firime yo gupfunyika ikwirakwizwa neza ku buryo bungana ku bintu bipfunyika, ikarinda stress idasanzwe ishobora kwangiza ibicuruzwa, ibyo bikaba bitagerwaho hakoreshejwe uburyo gakondo bwo gupfunyika nko gupfunyika, gupfunyika, na kaseti.
Uburyo bwo kugera ku bufatanye burimo ubwoko bubiri: bumwe ni ugushyiramo PIB cyangwa itsinda ryayo rinini kuri polymer, ubundi ni ukuvanga na VLDPE.
(1) PIB ni amazi abonerana kandi afite imiterere itose. Kongeramo ibintu mu buryo butaziguye bisaba ibikoresho byihariye cyangwa guhindura ibikoresho. Muri rusange, PIB masterbatch ikoreshwa. PIB ifite inzira yo kwimuka, akenshi imara iminsi itatu, kandi ikagira ingaruka ku bushyuhe. Ifite ubushobozi bwo gufata neza ku bushyuhe bwinshi kandi ikagira ubushobozi buke bwo gufata neza ku bushyuhe buke. Nyuma yo kurambura, ubushobozi bwayo bwo gufata bugabanuka cyane. Kubwibyo, firime irangiye ni byiza kubikwa mu bushyuhe runaka (ubushyuhe busabwa kubikwa: 15°C kugeza 25°C).
(2) Kuvanga na VLDPE bifite ubushobozi bwo gufatana butoya gato ariko ntibisaba ibikoresho byihariye. Uburyo bwo gufatana buhora buhamye, ntabwo bugengwa n'igihe ntarengwa, ariko kandi bugira ingaruka ku bushyuhe. Bufatana buto cyane ku bushyuhe buri hejuru ya 30°C kandi bugafatana buto cyane ku bushyuhe buri munsi ya 15°C. Guhindura ingano ya LLDPE mu gice cyo gufatana bishobora kugera ku bunini bwifuzwa. Ubu buryo bukunze gukoreshwa kuri filime zo gusohoramo ibice bitatu.
4. Ibiranga filime yo kugabanya uburebure bwa PE
(1) Guhuza: Iki ni kimwe mu biranga gupfunyika ibintu mu buryo burambuye, butuma ibicuruzwa bihambira neza mu buryo buto kandi buhamye, ndetse no mu bihe bibi, bikarinda ko ibicuruzwa bicika cyangwa ngo bitandukanywe. Gupfunyika ntabwo bifite impande zityaye cyangwa ngo bifatanye, bityo birinda kwangirika.
(2) Uburinzi bw'ibanze: Uburinzi bw'ibanze butanga uburinzi ku bicuruzwa, bigatuma inyuma hagaragara uburinzi bworoheje. Burinda ivumbi, amavuta, ubushuhe, amazi, n'ubujura. Gupfunyika ibyuma bipfunyika neza bikwirakwiza imbaraga ku bicuruzwa bipfunyitse, bikarinda kwimuka no kugenda mu gihe cyo kubitwara, cyane cyane mu nganda z'itabi n'imyenda, aho bifite ingaruka zidasanzwe zo gupfunyika.
(3) Kuzigama Ikiguzi: Gukoresha icyuma gipfunyika mu gupfunyika ibicuruzwa bishobora kugabanya ikiguzi cyo gukoresha. Filime ipfunyika ikoresha hafi 15% by'agapfunyika k'umwimerere, hafi 35% by'agapfunyika gashyuha, na hafi 50% by'agapfunyika k'amakarito. Bigabanya kandi imbaraga z'abakozi, bikongera imikorere myiza mu gupfunyika, kandi byongera amanota yo gupfunyika.
Muri make, urwego rwo gukoresha filime yo kudoda ni runini cyane, aho hari uturere twinshi mu Bushinwa tutarasuzumwa, n'uturere twinshi twasuzumwe tutarakoreshwa cyane. Uko urwego rwo gukoresha filime yo kudoda rugenda rwaguka, ikoreshwa rya filime yo kudoda rizagenda ryiyongera cyane, kandi ubushobozi bwayo ku isoko ni ntagereranywa. Kubwibyo, ni ngombwa guteza imbere cyane ikorwa n'ikoreshwa rya filime yo kudoda.
5. Imikoreshereze ya PE Stretch Film
Filimi yo gukurura ya PE ifite imbaraga nyinshi zo gukurura, irwanya amarira, ibonerana, kandi ifite ubushobozi bwo kugarura ibintu neza. Ifite igipimo cya 400% mbere yo gukurura, ishobora gukoreshwa mu gushyira mu bikoresho, mu kwirinda amazi, mu kwirinda ivumbi, mu kurwanya gukwirakwiza no kurwanya ubujura.
Ikoreshwa: Ikoreshwa mu gupfunyika amapaleti no mu bindi bipfunyika kandi ikoreshwa cyane mu bucuruzi bw'amahanga bwoherezwa mu mahanga, mu gukora amacupa n'amacupa, mu gukora impapuro, mu bikoresho by'amashanyarazi n'ibikoresho by'amashanyarazi, muri pulasitiki, mu bucuruzi bw'imiti, mu bwubatsi, mu buhinzi, mu biribwa, no mu zindi nganda.
