Uri kuda kugadzirisa mutsetse wako wekurongedza kana kuvandudza mashandiro ezvivakwa zvakaiswa laminated here? Gwaro iri rinoshanda rinoongorora misimboti yakakosha, kusarudzwa kwezvinhu, matanho ekugadzirisa, uye matekiniki ekugadzirisa matambudziko mu extrusion coating (inozivikanwawo se lamination) — tekinoroji inoshandiswa zvakanyanya muzvikamu zvekurongedza, zvekurapa, zvemotokari, uye zvemaindasitiri.

Chii chinonzi Lamination (Extrusion Coating) uye Inoshanda Sei?

Lamination, kana kuti extrusion coating, inzira inosanganisira kuputira purasitiki yakanyungudutswa (inowanzo kuve polyethylene, PE) zvakafanana pazvishandiso zvakaita sepepa, jira, zvisiri zvakarukwa, kana aluminium foil. Uchishandisa mudziyo weextrusion, purasitiki inonyungudutswa, inoputirwa, uye inotonhodzwa kuti igadzire chimiro chakabatana.

Nheyo huru ndeyekushandisa kuyerera kwepurasitiki yakanyungudutswa pakupisa kwakanyanya kuti ibatane zvakasimba ne substrate, nokudaro zvichiwedzera hunhu hwekudzivirira, kuvharika kwekupisa, uye kugara kwenguva refu kune hwaro hwepurasitiki.

Matanho Akakosha Ekuita Lamination

1. Kugadzira Zvinhu Zvisina Kugadzirwa: Sarudza mapurasitiki akakodzera (semuenzaniso, PE, PP, PLA) uye substrates (semuenzaniso, bepa risingashandiswi, jira risina kurukwa).

2. Kunyunguduka uye Kubuda kwePlastiki: Mapurasitiki anoiswa muchinhu chinonyunguduka, uko anonyungudutswa kuita mvura inonamira pakupisa kwakanyanya. Plastiki yakanyungudutswa inozoburitswa kuburikidza neT-die kuti iite kunyunguduka kwakafanana nefirimu.

3. Kuputira uye Kubatanidza: Firimu repurasitiki rakanyungudutswa rakaputirwa zvakanaka pamusoro pechinhu chisina kuvhurika pasi pekudzora kusimba. Panzvimbo yekuputira, purasitiki yakanyungudutswa nechinhu chacho zvinobatanidzwa zvakasimba pasi pesimba rema pressure rollers.

4. Kutonhodza uye Kugadzirisa: Chinhu chakabatanidzwa chinopfuura nekukurumidza nemaroller ekutonhodza, zvichibvumira purasitiki yakanyungudutswa kuti itonhodze nekukurumidza uye iome, zvichiita purasitiki yakasimba.

5. Kutenderedza: Zvinhu zvakasanganiswa zvakatonhorera uye zvakaiswa laminated zvinoputirwa kuita mipumburu kuti zvishandiswe uye zvigadziriswe.

6. Matanho Ekusarudza: Mune zvimwe zviitiko, kuti chigadziko chirambe chakabatana kana kuti chiwedzere kunaka kwechinhu chacho, chinogona kurapwa nekorona chisati chaiswa pendi.

Gwaro reKusarudza Substrate nePlastiki reExtrusion Coating kana Lamination

Zvinhu zvinoshandiswa mukuita lamination zvinosanganisira substrates nezvinhu zvinonamira (mapurasitiki).

1. Zvigadziko

2. Zvinhu zvekunamira (Mapurasitiki)

• Polyethylene (PE)

LDPE: Inochinjika zvakanyanya, inonyunguduka zvishoma, yakakodzera kuputirwa nepepa.

LLDPE: Simba guru rekudhonza uye kuramba kuboorwa, kazhinji zvinosanganiswa neLDPE.

HDPE: Inopa kusimba kwakanyanya uye kushanda zvakanaka kwezvipingamupinyi, asi inonetsa kugadzirisa.

• Polypropylene (PP)

Kuramba kupisa uye kuomarara kuri nani pane PE. Yakanakira kushandiswa kwekubvisa utachiona pakupisa kwakanyanya.

• Mapurasitiki anoora

PLA: Inopenya, inoora, asi haipindi kupisa zvakanyanya.

PBS/PBAT: Inochinjika uye inogona kugadziriswa; yakakodzera kugadzirisa mapurasitiki nenzira dzinogara kwenguva refu.

• MaPolymers Akakosha

EVOH: Chidziviriro chakanaka cheokisijeni, chinowanzo shandiswa sechikamu chepakati mupakeji yechikafu.

Ionomers: Kujeka kwakanyanya, kuramba mafuta, kugona kuvharwa zvakanaka.

Matambudziko Akajairika uye Mhinduro muExtrusion Coating uye Lamination:Gwaro Rinoshanda Rekugadzirisa Matambudziko

1. Matambudziko eKunamatira / Kuvhara

Zvinokonzera: Kusatonhodza kwakakwana, kumanikidzwa kwakanyanya kwekutenderera, kupararira kusina kukwana kana kusina kuenzana kwechinhu chinodzivirira kuvharika, tembiricha yakakwira yemhepo, uye hunyoro.

Mhinduro: Deredza tembiricha yekutonhodza inotenderera, wedzera nguva yekutonhodza; deredza kusimba kwemhepo nenzira yakakodzera; wedzera kana kuwedzera huwandu uye kupararira kwezvinodzivirira kuvharika (semuenzaniso, erucamide, oleamide, silica, SILlKE SILIMER series super slip uye anti-blocking masterbatch); vandudza tembiricha yemhepo uye hunyoro munzvimbo yekugadzira.

Tichisuma SILIKE SILIMER Series: High-Performance Slip uye Anti-Blocking Masterbatch yemafirimu akasiyana-siyana epurasitiki nemapolymers akagadziriswa.

Mabhenefiti Akakosha: Zvinotsvedza uye zvinodzivirira kuvharika kwePolyethylene Films

•Kushanda kwakawedzerwa kwekutsvedza uye kuvhura firimu

• Kugadzikana kwenguva refu mumamiriro ekunze anopisa zvakanyanya

• Hapana mvura inonaya kana hupfu (“hapana maruva”)

• Hapana kukanganisa kwakaipa pakudhinda, kuvhara kupisa, kana kuputira

• Inovandudza kuyerera kwekunyunguduka uye kupararira kwepigments, fillers, uye zvimwe zvinoshanda mukati me resin system.

Mhinduro dzeVatengi - Mhinduro dzeExtrusion Coating kana Lamination Applications:
Vagadziri vemafirimu epurasitiki vanoshandisa nzira dzekuputira miromo nekubvisa jira vanotaura kuti SILIMER inotsvedza uye inodzivisa kuvharika inogadzirisa matambudziko ekunamira miromo uye inovandudza zvakanyanya mashandiro ekugadzirisa jira rakagadzirwa nePE.

2. Simba Rekusvina Risina Kukwana (Delamination):

Zvinokonzera: Simba shoma pamusoro pevhu, kusakwana kwekurapwa kwekorona, tembiricha yakaderera yekubuda kwemvura, kumanikidzwa kusina kukwana kwekufukidza, uye kusawirirana pakati pepurasitiki nevhu.

Mhinduro: Wedzera simba rekurapa korona pa substrate; wedzera tembiricha yekubuda kwemvura kuti uwedzere kunyorova kwemvura inonyunguduka kusvika pasi; wedzera kumanikidzwa kwepurasitiki; sarudza zvinhu zvinonamira zvinoenderana zviri nani ne substrate, kana kuwedzera zvinobatanidza.

3. Zvikanganiso pamusoro (semuenzaniso, madodzi, maziso ehove, magadzirirwo emaganda eorenji):

Zvinokonzera: Kusachena, zvinhu zvisina kunyunguduka, hunyoro muzvinhu zvepurasitiki; kuchena kusina kunaka kwedhishi; tembiricha isina kugadzikana kana kumanikidzwa; kutonhora kusina kuenzana.

Mhinduro: Shandisa zvinhu zvepurasitiki zvakaoma zvemhando yepamusoro; geza die neextruder nguva dzose; gadzirisa maparamita eextrusion necooling.

4. Ukobvu husina kuenzana:

Zvinokonzera: Kusawirirana kwekupisa kwedivha, kugadziriswa kusina kunaka kwemukana wedivha, sikuruu yekuburitsa miromo yakasakara, ukobvu hwepasi pevhu husina kuenzana.

Mhinduro: Dzora tembiricha yedivha nemazvo; gadzirisa mukana wedivha yemiromo; gara uchichengetedza chinoburitsa mvura; chengetedza mhando yesubstrate.

5. Kusavharika Kunopisa:

Zvinokonzera: Kusakwana kweukobvu hwelaminated layer, tembiricha isina kunaka yekuvhara kupisa, kusarudzwa kusina kunaka kwezvinhu zvinosunga laminating.

Mhinduro: Wedzera ukobvu hwakagadzirwa nelaminate zvakakodzera; gadzirisa tembiricha, kumanikidzwa, nenguva; sarudza zvinhu zvinosunga nelaminate zvine hunhu huri nani hunovhara kupisa (semuenzaniso, LDPE, LLDPE).

Unoda Rubatsiro Pakugadzirisa Lamination Line Yako Kana Kusarudza YakaruramaChinowedzera chemafirimu epurasitiki uye kurongedza kwakachinjika?
Bata nechikwata chedu chehunyanzvi kana kuti tsvaga mhinduro dzeSILIKE dzakavakirwa pasilicone dzakagadzirirwa ma packaging converters.

SILIMER Series yedu inopa kushanda kwenguva refu uye kudzivirira kuvharika, inovandudza mhando yechigadzirwa, inoderedza zvikanganiso zvepachiso, uye inowedzera kushanda zvakanaka kwe lamination.

Siyanai nematambudziko akadai semvura yehupfu chena, kufamba kwemhepo, uye kusagadzikana kwemafirimu.

Semugadziri akavimbika wezvinowedzera zvemafirimu epurasitiki, SILIKE inopa mhando dzakasiyana dzemhinduro dzisingatsvedzerere uye dzinodzivirira kuvharika dzakagadzirirwa kuvandudza mashandiro emafirimu akavakirwa papolyolefin. Zvigadzirwa zvedu zvinosanganisira zvinodzivirira kuvharika, zvinowedzera kutsvedza uye zvinodzivirira kuvharika, zvinodzivirira kutsvedza zvine silicone, zvinodzivirira kutsvedza zvine tembiricha yakakwira uye yakagadzikana, zvinogara kwenguva refu, zvinobatsira mukuita zvinhu zvakawanda, uye zvinosimudzira mafirimu epolyolefin. Mhinduro idzi dzakanakira mashandisirwo ekuisa zvinhu mupurasitiki, zvichibatsira vagadziri kuwana hunhu hwepamusoro, kuderedza kuvharika kwemafirimu, uye kuvandudza kushanda zvakanaka kwekugadzira.

Taura nesu paamy.wang@silike.cn kuti uwane chinowedzera chakakodzera mafirimu ako epurasitiki uye zvinodiwa pakugadzira mapurasitiki zvinochinjika.
