Mafirimu eLDPE anowanzo kugadzirwa nezvose zviri zviviri kuumba nekukanda maitiro. Cast polyethylene film ine yunifomu ukobvu, asi haiwanzo shandiswa nekuda kwemutengo wayo wepamusoro. Flown polyethylene firimu inogadzirwa kubva kumhepo-yakaumbwa giredhi PE pellets nemichina yekuvhuvhuta, iyo inonyanya kushandiswa nekuda kwekuderera kwayo mutengo.

Yakaderera-density polyethylene firimu inoratidzika semi-pachena, inopenya, yakapfava magadzirirwo emufirimu, ine yakanakisa kugadzikana kwemakemikari, kupisa chisimbiso, kusamira kwemvura uye hunyoro kuramba, kutonhora kwechando, kunogona kubikwa. Mhedzisiro yaro huru ndiyo inovharira mweya weokisijeni, inowanzoshandiswa mumisanganiswa inochinjika yekurongedza zvinhu, iyo yemukati firimu, asi zvakare ndiyo inonyanya kushandiswa, huwandu hukuru hwepurasitiki yekurongedza firimu, inoverengera inopfuura 40% ye kushandiswa kwefirimu repurasitiki rekuputira.

Sezvo polyethylene molecule isina mapoka epolar uye ine chiyero chepamusoro chekristallinity uye yakaderera pamusoro pesimba remahara, firimu rine hurombo husina kunaka hwekudhinda uye husina kunaka hwekunamatira kune ingi uye zvinonamira, saka kurapwa kwepamusoro kunodiwa usati wadhinda uye laminating.

Izvi zvinotevera kutadza kwakajairwa uye mhinduro dzeLDPE yakafuridzwa firimu:

Firimu rinonamira zvakanyanya, kusavhurika zvakanaka

Kuongorora kwechikonzero:

1. The resin raw material haisi yemhando yakarurama, kwete kuputirwa firimu giredhi LDPE resin, iyo isina mumiriri wekuvhura kana kuvhura mumiriri wemhando yakaderera;

2. Tembiricha yeresin yakanyungudutswa yakanyanya kukwirira, fluidity yakakura kwazvo;

3. Kufuridzira reshiyo yakakura kwazvo, zvichikonzera kuvhurika kwemafirimu kwakashata;

4. Iko kutonhora kunononoka kunonoka, iyo firimu haina kutonhora zvakakwana, uye kubatana kunowanikwa pasi pechiito che traction roller pressure;

5. Iyo yekukweva inomhanya zvakanyanya.

Solutions

① Tsiva resin mbishi zvinhu, kana kuwedzera imwe huwandu hwekuvhura mumiriri kune hopper;

② Kudzikisa zvakakodzera tembiricha yeextrusion uye tembiricha yeresin;

③ Deredzai zvakakodzera kuvhuvhuta reshiyo;

④ Wedzera huwandu hwemhepo kuti uvandudze kutonhora mhedzisiro uye nekumhanyisa firimu kutonhora kumhanya;

⑤ Deredzai zvakafanira kumhanya-mhanya.

Kusajeka kwefirimu

Kuongorora kwechikonzero:

1. yakaderera extrusion tembiricha, murombo resin plasticization, zvichikonzera kushata pachena kwefirimu mushure mekuvhuvhuta kuumbwa;

2. Kufuridzira reshiyo idiki kwazvo;

3. Kusaita kutonhora kunokonzera, nokudaro kukanganisa kujeka kwefirimu;

4. Hunyoro huri mu resin mbishi zvinhu zvakakurisa;

5. Iyo yekudhonza kumhanya inokurumidza uye iyo firimu haina kutonhora zvakakwana.

Solution

① Wedzera zvakafanira tembiricha yeextrusion, kuitira kuti resin igone kuve yakafanana plasticized;

② Wedzera zvakafanira chiyero chekufuridza;

③ Wedzera huwandu hwemhepo kuti uvandudze kutonhora mhedzisiro;

③ Wedzera huwandu hwemhepo kuti uvandudze kutonhora maitiro;

④ Pukuta iyo mbishi;

⑤ Deredza kumhanya-mhanya nenzira kwayo.

Firimu wrinkles

Chikonzero chekuongorora

1. Kusaenzana kwefirimu ukobvu;

2. Kusakwana kutonhora mhedzisiro;

3. Mhepo inoputika yakakura kwazvo, zvichiita kuti bubble remufirimu rive risina kugadzikana, richizununguka nekudzoka kubva kune rumwe rutivi kuenda kune rumwe rutivi, saka firimu inowanzoita wrinkles;

4. Iko kona ye herringbone clamp yakakura zvikuru, bubble refirimu rinoputika mukati mechinguva chiduku, saka firimu inowanzoitawo kukwinya;

5. Kudzvinyirirwa kumativi ose maviri e-traction roller hakusi kuenderana, rumwe rutivi rwakakwirira uye rumwe rutivi rwakaderera;

6. Matemo ari pakati pevanotungamira rollers haana kufanana, izvo zvinokanganisa kugadzikana uye flatness yefirimu, nokudaro wrinkling inoitika.

Solution

① Gadzirisa ukobvu hwefirimu kuti uve nechokwadi chekukora yunifomu;

② Kuvandudza kutonhora kwekuita kuti uve nechokwadi chekuti firimu rinogona kunyatsotonhodzwa;

③ Deredzai zvakakodzera kuvhuvhuta reshiyo;

③ Deredza chiyero chekufuridza zvakakodzera;

④ Deredza kona yekunamatira yeherringbone clamp zvakakodzera;

⑤ Gadzirisa kudzvanywa kweiyo traction roller kuti uve nechokwadi chekuti firimu rinoiswa pasi pesimba rakafanana;

⑥ Tarisa axis yegidhi yega yega shaft uye ita kuti ifanane kune imwe neimwe.

Kushata kwekuvhara kupisa kwekuita kwefirimu

Chikonzero chekuongorora

1. Mutsara wechando wakanyanya kuderera, mapolymer molecules anotarisana, nokudaro achiita kuti kushanda kwefirimu kuswedere kune yefirimu yakatarisa, zvichiita kuti kupisa kwakadzika kuvhare kushanda;

2. The blowing reshiyo uye traction ratio yakakura kwazvo, uye firimu rinoenda kutambanudza kutaridzika, zvichikanganisa kupisa kwekuvhara kuita kwefirimu.

Solution

① Gadzirisa saizi yevhoriyamu yemhepo mumhete yemhepo kuita kuti dova rikwire zvishoma, nepazvinogona napo, pasi penzvimbo yekunyunguduka kwepurasitiki inovhuvhuta uye kudhonza, kuitira kuderedza mamorekuru nekuda kwekuvhuvhuta uye kukwenya kunokonzerwa ne. kutambanudza orientation;

② Kuvhuvhuta uye kudhonza reshiyo kunofanirwa kuve diki zvakafanira. Kana chiyero chekufuridza chakakurisa uye kumhanya kwekufambisa kuchimhanya zvakanyanya, firimu racho rakatambanudzwa munzira yakachinjika uye kureba, ipapo kuita kwefirimu kunowanzoita kunge kwakatambanudzwa, uye kupisa kwefirimu kuvharisa zvimiro zvinova zvisina kunaka.

Firimu rine hwema

Chikonzero chekuongorora

1. Resin raw material pachayo ine hwema;

2. The extrusion tembiricha resin yakanyungudutswa yakawandisa, izvo zvinoita kuti resin iparare, nokudaro ichiburitsa kunhuhwirira;

3. Kusakwana kutonhora kwemupumburu wefirimu, mhepo inopisa mukati memuputi wefirimu haina kubviswa.

Solution

① Tsiva resin mbishi zvinhu;

② Gadzirisa tembiricha yeextrusion;

③Kuvandudza kutonhora kwemhete yemhepo inotonhorera, kuitira kuti bhaisikopo remufirimu ritonhodzwe zvakakwana.

Muchena unonaya pamusoro pefirimu

Chikonzero: Inonyanya kuwedzererwa muzvigadzirwa, yakaderera mamorekuru uremu resin uye guruva, nezvimwewo, izvo zvinonamira pamuromo mold panguva yekugadziriswa, uye mushure mekuunganidza imwe chiyero inotorwa nefirimu nguva dzose, nekudaro ichigadzira White precipitates pafirimu.

Solution

①Mushure meimwe nguva yenguva, wedzera screw speed, wedzera kunyunguduka extrusion pressure, bvisa precipitates.

② Nguva dzose kuchenesa muromo mold.

③ Wedzera tembiricha yekunyungudika zvakakodzera kuti izere plasticize;

④ShandisaSILIEK PFAS-yemahara PPA masterbatchinogona kunyatso kuvandudza resin kugadzirisa fluidity, kunatsiridza mukati nekunze kwekuzora kuita, kunatsiridza kupararira pakati pezvikamu, kuderedza agglomeration, kunatsiridza muromo kufa kuunganidza, uye panguva imwechete inogona kuburitswa kubva pakona yakafa yemidziyo, nekudaro kuvandudza. kunaka kwepamusoro kwefirimu.SILIEK PFAS-yemahara PPA masterbatchndiyo nzira yakakwana kune fluorinated polymer PPA additives kuti isangane nezvinodiwa zvezvino zvinorambidzwa fluorine.SILIEK PFAS-yemahara PPA masterbatchinotsiva yakakwana yefluorinated polymer PPA additives, iyo inosangana nezvinodiwa zvezvino zvinorambidzwa fluorine.

⑤ Kushandiswa kweSILIKE SILIMER akatevedzana easina-precipitating firimu yakatsetseka yekuvhura mumiriri, kugadzirisa iyo yechinyakare yakatsetseka mumiriri iri nyore kuburitsa dambudziko rehupfu.

LDPE firimu mhinduro yekuvandudza chigadzirwa mhando

SILIMER Series Non-Precipitation Film Slip Masterbatchimhando yakagadziridzwa copolysiloxane ine inoshanda organic inoshanda mapoka akagadzirwa neSilicone. Iyo refu kabhoni cheni inoenderana neresin kuita basa rekumisa, uye iyo silicon cheni inoiswa pamusoro pefirimu kuti iite basa rekutsvedza, iro rinogona kuita basa rekutsvedza pasina kunaya kwakazara.

Kuwedzera shoma shoma yeSILIKE SILIMER 5064MB1, SILIMER 5064MB2uye mamwe akateedzana ezvigadzirwa anogona kuvandudza zvakanyanya kunaka kwefirimu, kusiyana neyakajairwa firimu talc,SILIMER akatevedzana emufirimu asina kunayatalc haina kudonha, haina kudonha kubva muhupfu, iyo coefficient of friction yakagadzikana, high-temperature talc haina kunamatira. Panguva imwecheteyo haikanganisi kushandiswa kunotevera kwefirimu, haikanganisi firimu kupisa chisimbiso kushanda, haikanganisi pachena kwefirimu, haikanganisi kudhinda, laminating nezvimwe zvakadaro.
