Izindaba

Ufuna ukwenza ngcono umugqa wakho wokupakisha noma ukuthuthukisa ukusebenza kwezakhiwo ezifakwe i-laminate? Lo mhlahlandlela osebenzayo uhlola izimiso ezibalulekile, ukukhethwa kwezinto, izinyathelo zokucubungula, kanye namasu okuxazulula izinkinga ekumbozweni kwe-extrusion (okwaziwa nangokuthi i-lamination) — ubuchwepheshe obusetshenziswa kabanzi emikhakheni yokupakisha, yezokwelapha, yezimoto, kanye neyezimboni.

Kuyini i-Lamination (i-Extrusion Coating) futhi isebenza kanjani?

I-Lamination, noma i-extrusion coating, inqubo ehilela ukumboza ipulasitiki encibilikisiwe (ngokuvamile i-polyethylene, i-PE) ngokufanayo ezintweni ezingaphansi komhlaba ezifana nephepha, indwangu, izinto ezingalukiwe, noma i-aluminium foil. Kusetshenziswa idivayisi ye-extrusion, ipulasitiki iyancibilikiswa, imbozwe, bese ipholiswa ukuze kwakhiwe isakhiwo esihlanganisiwe.

Isimiso esiyinhloko ukusebenzisa ukugeleza kwepulasitiki encibilikisiwe emazingeni okushisa aphezulu ukuze kufezwe ukubophana okuqinile ne-substrate, ngaleyo ndlela kwenezelwe izakhiwo zokuvimbela, ukuvala ukushisa, kanye nokuqina kwesisekelo sezinto.

Izinyathelo Zenqubo Yokugcotshwa Okuyisihluthulelo

1. Ukulungiswa Kwezinto Ezingavuthiwe: Khetha ama-pellet epulasitiki afanele (isib., i-PE, i-PP, i-PLA) kanye nama-substrate (isib., iphepha eliyi-virgin, indwangu engalukiwe).

2. Ukuncibilika Nokukhuculula Ipulasitiki: Ama-pellet epulasitiki afakwa ku-extruder, lapho ancibilikiswa khona abe uketshezi oluqinile emazingeni okushisa aphezulu. Ipulasitiki encibilikisiwe bese ikhishwa nge-T-die ukuze yakhe ukuncibilika okufana nefilimu.

3. Ukumboza Nokuhlanganisa: Ifilimu yepulasitiki encibilikisiwe imbozwe kahle ebusweni be-substrate engakavulwa ngaphansi kokulawulwa kokucindezeleka. Endaweni yokumboza, ipulasitiki encibilikisiwe kanye ne-substrate kuhlanganiswa ndawonye ngokuqinile ngaphansi kwesenzo sama-roller okucindezela.

4. Ukupholisa Nokubeka: Izinto ezihlanganisiwe zidlula ngokushesha kuma-roller okupholisa, okuvumela ungqimba lwepulasitiki oluncibilikisiwe ukuthi luphole ngokushesha futhi luqine, lwakha ifilimu eqinile yepulasitiki.

5. Ukugoqa: Izinto ezihlanganisiwe ezipholile nezibekwe phansi zihlanganiswa zibe imiqulu ukuze zicutshungulwe futhi zisetshenziswe ngokulandelayo.

6. Izinyathelo Ongazikhetha: Kwezinye izimo, ukuze kuthuthukiswe ukunamathela kwesendlalelo esinamathelisiwe noma kuthuthukiswe izakhiwo zomphezulu, i-substrate ingase iphathwe nge-corona ngaphambi kokumbozwa.

Umhlahlandlela Wokukhetha I-Substrate kanye nePlastiki Wokumboza noma Ukumboza Okungeziwe

Izinto ezihilelekile enkambisweni yokubopha ama-lamination zifaka phakathi izinto zokubopha ama-lamination (amapulasitiki).

1. Izingxenyana

2. Izinto Zokunamathisela (Amapulasitiki)

• I-Polyethylene (PE)

I-LDPE: Ukuguquguquka okuhle kakhulu, indawo yokuncibilika ephansi, ilungele ukuncibilika kwephepha.

I-LLDPE: Amandla aphezulu okudonseka kanye nokumelana nokubhoboza, okuvame ukuhlanganiswa ne-LDPE.

I-HDPE: Inikeza ukuqina okuphezulu nokusebenza kwezithiyo, kodwa kunzima kakhulu ukuyicubungula.

• I-Polypropylene (PP)

Ukumelana nokushisa okungcono kanye nokuqina kune-PE. Kulungele ukusetshenziswa kokubulala amagciwane okushisa okuphezulu.

• Amapulasitiki abolayo

I-PLA: Icacile, iyabola, kodwa ilinganiselwe ekumelaneni nokushisa.

I-PBS/PBAT: Iyaguquguquka futhi ingacutshungulwa; ifanele izixazululo zokupakisha eziqhubekayo.

• Ama-Polymer Akhethekile

I-EVOH: Isithiyo esihle kakhulu se-oxygen, esivame ukusetshenziswa njengengqimba ephakathi ekupakisheni kokudla.

Ama-Ionomers: Ukucaca okuphezulu, ukumelana nowoyela, ukuqina kokuvala okuhle kakhulu.

Izinkinga Nezixazululo Ezivamile Ekumbozweni Kwe-Extrusion kanye ne-Lamination:Umhlahlandlela Owusizo Wokuxazulula Izinkinga

1. Izinkinga Zokunamathela/Zokuvimba

Izimbangela: Ukupholisa okunganele, ukucindezeleka okukhulu kokugoba, ukuhlakazeka okunganele noma okungalingani kwe-anti-blocking agent, izinga lokushisa eliphezulu, kanye nomswakama.

Izixazululo: Yehlisa izinga lokushisa le-roller yokupholisa, yandisa isikhathi sokupholisa; nciphisa ngokufanele ukucindezeleka kokujikeleza; yandisa noma yenza ngcono inani kanye nokusabalala kwama-anti-blocking agents (isb., i-erucamide, i-oleamide, i-silica, i-SILlKE SILIMER series super slip kanye ne-anti-blocking masterbatch); thuthukisa izinga lokushisa elizungezile kanye nomswakama endaweni yokukhiqiza.

Sethula uchungechunge lwe-SILIKE SILIMER: I-High-Performance Slip kanye ne-Anti-Blocking Masterbatch yamafilimu ahlukahlukene epulasitiki kanye nama-Modified Polymers.

Izinzuzo Eziyinhloko Ama-Slips nama-anti-blocking agents e-Polyethylene Films

•Ukusebenza okuthuthukisiwe kokuvula nokushelela kwefilimu

• Ukuqina kwesikhathi eside ngaphansi kwezimo zokushisa okuphezulu

• Akukho mvula noma ukukhishwa kwempuphu (“akukho mphumela wokuqhakaza”)

• Akukho mthelela omubi ekuphrinteni, ekuvaleni ukushisa, noma ekushiseni

• Kuthuthukisa ukugeleza kokuncibilika kanye nokusabalala kwama-pigment, ama-filler, kanye nezithasiselo ezisebenzayo ngaphakathi kohlelo lwe-resin.

Impendulo Yamakhasimende – Izixazululo Zokufaka I-Extrusion Coating noma Izicelo Zokufaka I-Lamination:
Abakhiqizi bamafilimu epulasitiki abasebenzisa izinqubo zokumboza nge-lamination kanye ne-extrusion babika ukuthi ama-SILIMER slip kanye nama-anti-blocking agents axazulula ngempumelelo izinkinga zokunamathela kwezindebe ezidayiwe futhi athuthukisa kakhulu ukusebenza kahle kokucubungula ezimbozweni ezisekelwe ku-PE.

2. Amandla Okunganele Okuhluma (Ukuhlukaniswa Kwezinhlayiya):

Izimbangela: Amandla aphansi ongaphezulu kwe-substrate, ukwelashwa okunganele kwe-corona, izinga lokushisa eliphansi kakhulu lokukhipha, ukucindezela okwanele kokumboza, kanye nokungafani phakathi kwepulasitiki ne-substrate.

Izixazululo: Thuthukisa umphumela wokwelashwa kwe-corona ku-substrate; khulisa izinga lokushisa lokukhipha ukuze uthuthukise ukumanzisa kokuncibilika ku-substrate; khulisa ingcindezi yokumboza; khetha Izinto zokulamina ezihambisana kangcono ne-substrate, noma engeza ama-coupling agents.

3. Amaphutha Okungaphezulu (isib. amabala, amehlo enhlanzi, ukuthungwa kwekhasi eliwolintshi):

Izimbangela: Ukungcola, izinto ezingancibilikisiwe, umswakama ezintweni zokusetshenziswa zepulasitiki; ukuhlanzeka okubi kwedayi; izinga lokushisa noma ingcindezi yokukhipha engazinzile; ukupholisa okungalingani.

Izixazululo: Sebenzisa izinto zokusetshenziswa zepulasitiki ezomile nezisezingeni eliphezulu; hlanza njalo idayisi kanye ne-extruder; lungisa amapharamitha okukhipha kanye nokupholisa.

4. Ubukhulu Obungalingani:

Izimbangela: Ukushisa okungalingani kwe-die, ukulungiswa okungafanele kwegebe le-die lip, isikulufu se-extruder esigugile, ukujiya kwe-substrate okungalingani.

Izixazululo: Lawula izinga lokushisa le-die ngokunembile; lungisa igebe le-die lip; gcina njalo i-extruder; qinisekisa ikhwalithi ye-substrate.

5. Ukuvaleka Okubi Kokushisa:

Izimbangela: Ukujiya okunganele kwengqimba elaminethiwe, izinga lokushisa elingafanele lokuvala ukushisa, ukukhetha okungafanele kwezinto ezilaminethiwe.

Izixazululo: Khulisa ngokufanele ukujiya okufakwe i-laminate; lungiselela izinga lokushisa lokuvala ukushisa, ingcindezi, nesikhathi; khetha izinto zokunamathisela i-laminate ezinezakhiwo ezingcono zokuvala ukushisa (isb., i-LDPE, i-LLDPE).
