Urashaka kunoza umurongo wawe wo gupakira cyangwa kunoza imikorere y'inyubako za laminated? Iyi nyandiko ifasha mu gusuzuma amahame y'ingenzi, guhitamo ibikoresho, intambwe zo gutunganya, n'uburyo bwo gukemura ibibazo mu gupfuka (bizwi kandi nka lamination) - ikoranabuhanga rikoreshwa cyane mu gupfuka, ubuvuzi, imodoka, n'inganda.

Gusiga Lamination (Extrusion Coating) ni iki kandi bikora gute?

Gusiga irangi, cyangwa gusiga irangi ryo gusohora, ni inzira ikubiyemo gusiga irangi rya pulasitiki ishongeshejwe (akenshi muri polyethylene, PE) ku buryo bumwe ku bintu nk'impapuro, imyenda, ibitari ibyoboshye, cyangwa impapuro za aluminiyumu. Hakoreshejwe igikoresho cyo gusohora, irashongeshwa, igasigwa, hanyuma igakonjeshwa kugira ngo habeho imiterere ivanze.

Ihame ry'ingenzi ni ugukoresha uburyo pulasitiki ishongeshejwe ikora neza ku bushyuhe bwinshi kugira ngo ifatanye neza n'ubutaka, bityo yongeraho imiterere y'insinga, ubushobozi bwo gufunga ubushyuhe, no kuramba ku gikoresho cy'ibanze.

Intambwe z'ingenzi zo gusiga Lamination

1. Gutegura ibikoresho fatizo: Hitamo uduce twa pulasitiki dukwiye (urugero: PE, PP, PLA) n'uduce duto (urugero: impapuro zisanzwe, umwenda utari uboshye).

2. Gushonga no Gusohora Plastiki: Uduce twa pulasitiki dushyirwa mu cyuma gishongesha, aho dushongeshwa mu mazi afite ubushyuhe bwinshi. Hanyuma plastiki ishongeshwa inyuzwa muri T-die kugira ngo ikore ikintu kimwe kimeze nk'ifirime.

3. Gusiga no Guteranya: Ifiriti ya pulasitiki ishongeshejwe iratwikirwa neza ku buso bw'ipasi mbere yo gukurwaho igenzurwa n'imbaraga. Aho ipasi itwikiriwe, pulasitiki ishongeshejwe n'ipasi birafatanye cyane bitewe n'ibikoresho bigabanya umuvuduko.

4. Gukonjesha no Gushyiraho: Ibikoresho bivanze binyura vuba mu byuma bikonjesha, bigatuma urwego rwa pulasitiki ishongeshejwe rukonja vuba kandi rugakomera, bigatuma habaho icyuma gikomeye cya pulasitiki.

5. Gupfunyika: Ibikoresho bivanze byakonjeshejwe kandi byashyizwemo laminated bishyirwamo imizingo kugira ngo bitunganywe kandi bikoreshwe nyuma.

6. Intambwe z'ubushake: Hari ubwo, kugira ngo urwego rwa laminated rurusheho gufatana cyangwa kongera imiterere y'ubuso, substrate ishobora kuvurwa korona mbere yo gusigwa.

Inyigisho zo Guhitamo Substrate na Plastiki mu Gusiga cyangwa Gusiga Lamination

Ibikoresho bigira uruhare mu gikorwa cyo gusiga amavuta birimo cyane cyane ibikoresho byo gusiga amavuta (plastiki).

1. Ibice by'ingenzi

2. Ibikoresho byo gusiga amavuta (Plastike)

• Polyethylene (PE)

LDPE: Ifite ubushobozi bwo koroha cyane, ishongesha buhoro, ikaba nziza cyane mu gushonga impapuro.

LLDPE: Ifite imbaraga nyinshi zo gukurura no kudapfunyika, akenshi ivanze na LDPE.

HDPE: Itanga ubushobozi bwo gukomera no gukora neza kw'inzitizi, ariko biragoye kuyitunganya.

• Polypropylene (PP)

Ubudahangarwa bw'ubushyuhe n'ubudahangarwa kurusha PE. Ni byiza cyane mu gukoresha uburyo bwo gusukura mu bushyuhe bwinshi.

• Plasitiki zishobora kubora

PLA: Irabagirana, irabora, ariko idashobora kwihanganira ubushyuhe.

PBS/PBAT: Yoroshye kandi irashobora gutunganywa; ikwiriye ibisubizo birambye byo gupfunyika.

• Polymers zidasanzwe

EVOH: Ingufu nziza cyane zo kurinda umwuka wa ogisijeni, ikunze gukoreshwa nk'urwego rwo hagati mu gupfunyika ibiryo.

Ionomers: Ifite ubuziranenge bwinshi, irwanya amavuta, kandi ifunga neza cyane.

Ibibazo n'ibisubizo bikunze kugaragara mu gusiga no gusiga amavuta akoreshwa mu gukurura:Inyigisho Ifatika yo Gukemura Ibibazo

1. Ibibazo byo gufata / Kuziba

Impamvu: Ubukonje budahagije, umuvuduko ukabije wo kuzunguruka, ikwirakwira rihagije cyangwa ringana ry’ibintu birwanya impanuka, ubushyuhe bwinshi bw’ikirere n’ubushuhe.

Ibisubizo: Kugabanya ubushyuhe bw'udupira two gukonjesha, kongera igihe cyo gukonjesha; kugabanya imbaraga zo guhindagurika kw'ikirere mu buryo bukwiye; kongera cyangwa kunoza ingano n'ikwirakwira ry'ibintu birwanya gufunga (urugero: erucamide, oleamide, silica, SILlKE SILIMER series super slip na anti-blocking masterbatch); kunoza ubushyuhe n'ubushuhe mu bidukikije.

Tubagezaho urukurikirane rwa SILIKE SILIMER: High-Performance Slip and Anti-Blocking Masterbatch kuri filime zitandukanye za pulasitiki na polymers zahinduwe.

Ibyiza by'ingenzi: Indabyo zo gucika no gukumira ibyuma bya polyethylene

•Uburyo bworoshye bwo gufungura no gusohora filime

• Gutuza igihe kirekire mu gihe cy'ubushyuhe bwinshi

• Nta mvura cyangwa ifu (“nta ngaruka z’indabyo”)

• Nta ngaruka mbi ku icapiro, gufunga ubushyuhe, cyangwa gufunga

• Inoza urujya n'uruza rw'ibimera bishonga n'ibikwirakwira mu marangi, ibirungo byuzuza, n'ibindi bikoresho bikora neza muri sisitemu ya resin.

Ibitekerezo ku bakiliya – Uburyo bwo gusiga cyangwa gukoresha lamination:
Abakora filime za pulasitiki bakoresha uburyo bwo gusiga irangi no gutwikira bavuga ko imiti igabanya ubushyuhe ya SILIMER ikemura neza ibibazo byo gufata iminwa kandi ikongera cyane imikorere myiza mu gusiga irangi rishingiye kuri PE.

2. Ingufu zidahagije zo gukata (Delamination):

Impamvu: Ingufu nke zo ku butaka, uburyo bwo kuvura corona budahagije, ubushyuhe buke cyane bwo gusohora, umuvuduko udahagije wo gutwikira, ndetse no kutamenyana hagati ya pulasitiki n'ubutaka.

Ibisubizo: Kunoza ingaruka zo kuvura korona ku butaka; kongera ubushyuhe bukwiye bwo gusohora kugira ngo wongere ubushobozi bwo gushonga ku butaka; kongera umuvuduko wo gutwikira; guhitamo ibikoresho bihuza neza n'ubutaka, cyangwa kongeramo ibikoresho bihuza.

3. Ubusembwa bwo hejuru (urugero: uduce duto, amaso y'amafi, imiterere y'igishishwa cy'umuhondo):

Impamvu: Umwanda, ibintu bitashongeshejwe, ubushuhe mu bikoresho fatizo bya pulasitiki; isuku nke y'icyuma; ubushyuhe cyangwa igitutu kidahindagurika; ubukonje butaringaniye.

Ibisubizo: Koresha ibikoresho fatizo bya pulasitiki byumye kandi byiza; sukura buri gihe icyuma gikoresha amashanyarazi n'icyuma gikoresha amashanyarazi; ongera uburyo bwo gusohora no gukonjesha.

4. Ubunini budasa:

Impamvu: Ubushyuhe bw'umurabyo budahuje, gukosora nabi icyuho cy'iminwa, vis yo gusohora umunwa yashaje, ubugari bw'umurabyo budahuje.

Ibisubizo: Genda neza ubushyuhe bw'inkwi; hindura icyuho cy'iminwa y'inkwi; komeza buri gihe icyuma gisohora inkwi; menya neza ko ari nziza.

5. Kudapfa gufunga neza ubushyuhe:

Impamvu: Ubunini budahagije bw'urwego rwa laminated, ubushyuhe budahagije bwo kuziba ubushyuhe, guhitamo nabi ibikoresho bya laminated.

Ibisubizo: Ongera ubugari bukwiye bwa laminated; ongera ubushyuhe, umuvuduko, n'igihe bifunga ubushyuhe; hitamo ibikoresho bifunga ubushyuhe bifite ubushobozi bwiza bwo gufunga ubushyuhe (urugero, LDPE, LLDPE).

Ukeneye ubufasha mu kunoza umurongo wawe wo gusigamo lamination cyangwa guhitamo nezaInyongeramusaruro kuri filime za pulasitiki no gupfunyika mu buryo bworoshye?
Huza n'ikipe yacu y'ikoranabuhanga cyangwa ushakishe ibisubizo bya SILIKE bishingiye kuri silicone byagenewe abahindura ibikoresho byo gupakira.

Uruhererekane rwacu rwa SILIMER rutanga umusaruro urambye wo kunyerera no gukumira impanuka, rukongera ireme ry'ibicuruzwa, rugabanya inenge zo ku buso, kandi rukongera imikorere myiza ya lamination.

Garagaza ibibazo nko kumena ifu yera, kwimuka kw'ivu, n'imiterere idahuye ya firime.

Nk’umukora w’inyongeramusaruro za pulasitiki wizewe, SILIKE itanga uburyo bwinshi bwo gupima no gukumira impanuka bugamije kunoza uburyo bwo gutunganya no gukora neza filime zishingiye kuri polyolefin. Ibicuruzwa byacu birimo inyongeramusaruro zirwanya impanuka, ibyuma birwanya impanuka, ibikoresho birwanya impanuka bishingiye kuri silicone, inyongeramusaruro zihindagurika kandi zirambye, zifasha mu mikorere myinshi, hamwe n’inyongeramusaruro za filime za polyolefin. Ibi bisubizo ni byiza cyane mu gupakira ibintu byoroshye, bifasha abakora gukora kugira ngo bagere ku bwiza bw’ubuso, kugabanya impanuka, no kunoza imikorere.

Twandikire kuriamy.wang@silike.cn kugira ngo ubone inyongeramusaruro nziza ijyanye na filime za pulasitiki zawe n'ibyo ukeneye mu gupakira byoroshye.
