Izindaba

Ingabe ufuna ukuthuthukisa ulayini wakho wokupakisha noma uthuthukise ukusebenza kwezakhiwo ezinamalayini? Lo mhlahlandlela osebenzayo uhlola izimiso ezibalulekile, ukukhethwa kwempahla, izinyathelo zokucubungula, nezindlela zokuxazulula inkinga ku-extrusion coating (eyaziwa nangokuthi i-lamination) - ubuchwepheshe obusetshenziswa kakhulu emikhakheni yokupakisha, yezokwelapha, yezimoto, neyezimboni.

Iyini i-Lamination (Extrusion Coating) futhi Isebenza Kanjani?

I-Lamination, noma i-extrusion coating, iyinqubo ehilela ukumboza ipulasitiki encibilikisiwe (imvamisa ngokuvamile i-polyethylene, i-PE) ngokufanayo kuma-substrates afana nephepha, indwangu, okungezona izinto ezilukiweyo, noma ucwecwe lwe-aluminium. Ngokusebenzisa i-extrusion device, ipulasitiki iyancibilika, iboshwe, futhi ipholiswe ukuze yakhe isakhiwo esiyinhlanganisela.

Umgomo oyinhloko uwukusebenzisa ubumanzi bepulasitiki encibilikisiwe emazingeni okushisa aphezulu ukuze kuzuzwe ukuhlangana okuqinile ne-substrate, ngaleyo ndlela kwenezela izici zokuvimbela, ukuvaleka kokushisa, nokuqina kwesisekelo.

Izinyathelo Ezibalulekile Zenqubo Ye-Lamination

1. Ukulungiswa Kwempahla Engahluziwe: Khetha amapellets epulasitiki afanelekile (isb., i-PE, PP, PLA) kanye nama-substrates (isb., iphepha elimsulwa, indwangu engalukiwe).

2. Ukuncibilika Nokukhishwa Kwepulasitiki: Ama-pellets epulasitiki afakwa ku-extruder, lapho ancibilikiswa khona abe uketshezi lwe-viscous emazingeni okushisa aphezulu. Ipulasitiki encibilikisiwe ibe isikhishwa nge-T-die ukuze kwakheke ukuncibilika okufana nefilimu.

3. Ukumboza nokuhlanganisa: Ifilimu yepulasitiki encibilikisiwe imbozwe ngokunembile phezu kwengxenye engaphansi yangaphambi kokulimala ngaphansi kokulawula ukucindezeleka. Endaweni yokugqoka, ipulasitiki encibilikisiwe kanye ne-substrate ihlanganiswe ngokuqinile ngaphansi kwesenzo se-pressure rollers.

4. Ukupholisa Nokusetha: Izinto ezihlanganisiwe zidlula ngokushesha kumarola okupholisa, okuvumela ungqimba lwepulasitiki oluncibilikisiwe ukuthi luphole ngokushesha futhi luqine, lwenza ifilimu yepulasitiki eqinile.

5. Ukusonta: Impahla eyinhlanganisela epholile futhi esethiwe igaywa ibe amaroli ukuze icutshungulwe futhi isetshenziswe.

6. Izinyathelo Ongazikhetha: Kwezinye izimo, ukuze kuthuthukiswe ukunamathela kongqimba olune-laminated noma ukuthuthukisa izakhiwo ezingaphezulu, i-substrate ingase ithole ukwelashwa kwe-corona ngaphambi kokumbozwa.

I-Substrate kanye Nomhlahlandlela Wokukhetha wePlastiki we-Extrusion Coating noma Lamination

Izinto ezihilelekile ekusetshenzisweni kwe-lamination ngokuyinhloko zihlanganisa ama-substrates kanye nezinto zokwakha (amapulasitiki).

1. Ama-substrates

2. Izinto Zokucwenga (Ipulasitiki)

• I-Polyethylene (PE)

I-LDPE: Ukuguquguquka okuhle kakhulu, indawo encibilikayo ephansi, ilungele ukufakwa kwephepha.

I-LLDPE: Amandla aphakeme aqinile kanye nokumelana nokubhoboza, kuvame ukuhlanganiswa ne-LDPE.

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

• I-Polypropylene (PP)

Ukumelana nokushisa okungcono kanye nokuqina kune-PE. Ilungele izinhlelo zokusebenza zokuvala izinga lokushisa eliphezulu.

• I-Biodegradable Plastics

I-PLA: Ingafihli, iyabola, kodwa ikhawulelwe ukumelana nokushisa.

I-PBS/PBAT: Iyavumelana nezimo futhi iyacutshungulwa; ilungele izixazululo ezisimeme zokupakisha.

• I-Specialty Polymers

I-EVOH: Isithiyo esihle kakhulu se-oxygen, esivame ukusetshenziswa njengesendlalelo esimaphakathi ekufakweni kokudla.

Ama-Ionomers: Ukucaca okuphezulu, ukumelana nowoyela, ukuvala uphawu okuhle kakhulu.

Izinkinga Ezivamile Nezixazululo Ku-Extrusion Coating and Lamination:Umhlahlandlela Osebenzayo Wokuxazulula Izinkinga

1. Izinkinga zokunamathela / zokuvimba

Izimbangela: Ukupholisa okunganele, ukushuba kwamajika okweqile, ukuhlakazeka okunganele noma okungalingani kwe-ejenti evimbela ukuvinjwa, izinga lokushisa eliphezulu le-ambient, kanye nomswakama.

Izixazululo: Izinga lokushisa eliphansi lokupholisa i-roller, ukwandisa isikhathi sokupholisa; ukunciphisa ngokufanele ukushuba kwamajika; ukwandisa noma ukwandisa inani kanye nokuhlakazwa kwama-anti-blocking agents (isb, i-erucamide, i-oleamide, i-silica, i-SILLKE SILIMER series super slip kanye ne-anti-blocking masterbatch); ngcono izinga lokushisa elizungezile kanye nomswakama endaweni yokukhiqiza.

Sethula Uchungechunge lwe-SILIKE SILIMER: Isiliphu Esisebenza Kakhulu kanye ne-Anti-Blocking Masterbatch yamafilimu Ahlukahlukene Epulasitiki kanye nama-Polymers Aguquliwe.

Izinzuzo Eziyinhloko Isiliphu kanye nama-anti-blocking agents amafilimu e-Polyethylene

•Ukusebenza okuthuthukisiwe kweziliphu nokuvula ifilimu

• Ukuzinza kwesikhathi eside ngaphansi kwezimo ezisezingeni eliphezulu

• Akukho mvula noma impushana (umphumela “wokuqhakaza”)

• Awukho umthelela omubi ekunyatheliseni, ekuvaleni ukushisa, noma ekufakeni insimbi

• Ithuthukisa ukugeleza kokuncibilika nokusakazwa kombala, izigcwalisi, nezithasiselo ezisebenzayo ngaphakathi kwesistimu ye-resin.

Impendulo Yekhasimende – I-Extrusion Coating noma Izixazululo Zezicelo Ze-lamination:
Abakhiqizi bamafilimu epulasitiki abasebenzisa izinqubo zokumboza i-lamination kanye ne-extrusion babika ukuthi i-SILIMER slip kanye nama-anti-blocking agents axazulula ngokuphumelelayo izinkinga zokunamathela ezindebeni zokufa futhi athuthukise ngokuphawulekayo ukucubungula ukusebenza kahle kwezingubo ezisekelwe e-PE.

2. Amandla ePeel Anganele (Delamination):

Izimbangela: Amandla e-substrate aphansi, ukwelashwa kwe-corona okunganele, izinga lokushisa eliphansi kakhulu le-extrusion, ukucindezela okunganele kokumboza, nokungafani phakathi kwepulasitiki ne-substrate.

Izixazululo: Thuthukisa umphumela wokwelashwa kwe-corona ku-substrate; ukwandisa ngokufanele izinga lokushisa le-extrusion ukuze kuthuthukiswe ukumanzisa kokuncibilika ku-substrate; ukwandisa ingcindezi yokugqoka; khetha Izinto zokwakha ezihambisana kangcono ne-substrate, noma engeza ama-coupling agents.

3. Ukonakala kwendawo (isb., amachashaza, amehlo ezinhlanzi, ukuthungwa kwekhasi lewolintshi):

Izimbangela: Ukungcola, izinto ezingancibilikisiwe, umswakama ezintweni zokusetshenziswa zepulasitiki; ukungahlanzeki kahle kwefa; izinga lokushisa le-extrusion elingazinzile noma ingcindezi; ukupholisa okungalingani.

Izixazululo: Sebenzisa izinto zokusetshenziswa zepulasitiki ezomile ezisezingeni eliphezulu; hlanza njalo i-die kanye ne-extruder; nokwandisa extrusion kanye nokupholisa nemingcele.

4. Ubukhulu obungalingani:

Izimbangela: izinga lokushisa elingalingani lokufa, ukulungiswa okungafanele kwegebe lezindebe ezifayo, isikulufu esigqokwayo se-extruder, ukujiya kwe-substrate engalingani.

Izixazululo: Lawula ngokunembile izinga lokushisa lokufa; lungisa igebe lezindebe zokufa; gcina i-extruder njalo; qinisekisa ikhwalithi ye-substrate.

5. Ukungavaleki kahle kokushisa:

Izimbangela: Ubukhulu bengqimba ye-laminated enganele, izinga lokushisa elingafanele lokuvalwa kokushisa, ukukhethwa okungalungile kwempahla yokugcoba.

Izixazululo: Khulisa ngokufanele ukushuba kwe-laminated; thuthukisa izinga lokushisa lokuvalwa kokushisa, ingcindezi, nesikhathi; khetha izinto zokubeka i-laminating ezinezakhiwo ezingcono ezivaleka ukushisa (isb, i-LDPE, i-LLDPE).

Udinga Usizo Lokuthuthukisa Ulayini Wakho Wokubopha noma Ukukhetha OkulungileIngeza amafilimu ePlastiki kanye nokupakishwa okuguquguqukayo?
Xhumana nethimba lethu lezobuchwepheshe noma uhlole izixazululo ze-SILIKE ezisekelwe ku-silicone ezenzelwe iziguquli zokupakisha.

I-SILIMER Series yethu iletha ukusebenza okushelelayo nokusebenza kokuvimbela ukuvimbela, ithuthukisa ikhwalithi yomkhiqizo, inciphise ukonakala kwendawo, futhi ikhulise ukusebenza kahle kwe-lamination.

Valelisa ezindabeni ezifana nemvula yempushana emhlophe, ukufuduka, kanye nezakhiwo zefilimu ezingahambisani.

Njengomkhiqizi othenjwayo wezithasiselo zefilimu yepulasitiki, i-SILIKE inikeza uhla olubanzi lwesiliphu esingesona imvula kanye nezixazululo ezilwa nokuvimbela eziklanyelwe ukuthuthukisa ukucutshungulwa nokusebenza kwamafilimu asekelwe ku-polyolefin. Iphothifoliyo yethu yomkhiqizo ihlanganisa izithasiselo ezivimbela ukuvinjwa, ama-slip masterbatches ashelelayo kanye nama-anti-block, ama-slip agents asuselwa ku-silicone, izinga lokushisa eliphezulu nezinzile, izithasiselo ezishelelayo ezihlala isikhathi eside, izinsiza zezinqubo eziningi, kanye nezithasiselo zefilimu ye-polyolefin. Lezi zixazululo zilungele izinhlelo zokusebenza zokupakisha eziguquguqukayo, zisiza abakhiqizi ukuthi bathole ikhwalithi engaphezulu ethuthukisiwe, ukuvinjwa kwefilimu okuncishisiwe, kanye nokusebenza kahle kokukhiqiza okuthuthukisiwe.

Xhumana nathi kuamy.wang@silike.cn ukuthola isengezo esilungile samafilimu akho epulasitiki kanye nezidingo zokukhiqiza ukupakisha eziguquguqukayo.
