LDPE zaj duab xis feem ntau yog tsim los ntawm ob qho tib si tshuab moulding thiab casting txheej txheem. Cam khwb cia polyethylene zaj duab xis muaj cov tuab tuab, tab sis tsis tshua siv vim nws tus nqi siab. Blown polyethylene zaj duab xis yog tsim los ntawm tshuab moulded qib PE pellets los ntawm tshuab moulding tshuab, uas yog siv dav tshaj plaws vim nws cov nqi qis dua.

Low-density polyethylene zaj duab xis yog ib nrab pob tshab, glossy, mos zoo nkauj ntawm zaj duab xis, nrog rau cov tshuaj lom neeg ruaj khov zoo, kev sib khi kub, dej tsis kam thiab noo noo tsis kam, khov ua haujlwm, tuaj yeem boiled. Nws qhov teeb meem tseem ceeb yog qhov tsis zoo rau cov pa oxygen, feem ntau siv rau hauv cov khoom ntim khoom sib xyaw ua ke, cov txheej hauv cov yeeb yaj kiab, tab sis kuj yog tam sim no siv ntau tshaj plaws, qhov loj tshaj plaws ntawm cov yas ntim zaj duab xis, suav txog ntau dua 40% ntawm kev noj cov yas ntim zaj duab xis.

Txij li cov polyethylene molecule tsis muaj pawg polar thiab muaj qib siab ntawm crystallinity thiab tsis tshua muaj lub zog tsis muaj zog, zaj duab xis muaj cov khoom luam tawm tsis zoo thiab tsis zoo adhesion rau inks thiab adhesives, yog li kev kho saum npoo yuav tsum tau ua ntej luam ntawv thiab laminating.

Cov hauv qab no yog cov kev ua tsis tiav thiab kev daws teeb meem rau LDPE cua tshuab:

Zaj duab xis heev nplaum, tsis zoo openability

Kev soj ntsuam ua rau:

1. Cov khoom siv raw khoom tsis yog hom zoo, tsis yog tshuab cua tshuab qib LDPE resin, uas tsis muaj tus neeg sawv cev qhib lossis tus neeg sawv cev qhib yog qis dua;

2. Qhov kub ntawm cov molten resin yog siab dhau lawm, lub fluidity loj heev;

3. Qhov sib piv ntawm lub tshuab yog loj heev, ua rau cov yeeb yaj kiab tsis zoo;

4. Cov cua txias ceev yog qeeb heev, cov yeeb yaj kiab tsis txias txaus, thiab kev sib koom ua ke tshwm sim nyob rau hauv qhov kev txiav txim ntawm traction roller siab;

5. Lub traction ceev ceev heev.

Kev daws teeb meem

① Hloov cov khoom siv raw, lossis ntxiv qee qhov ntawm tus neeg sawv cev qhib rau lub hopper;

② Tsim nyog txo qhov kub thiab txias ntawm cov resin;

③ Tsim nyog txo cov tshuab tshuab;

④ Ua kom cov cua ntim los txhim kho cov cua txias thiab ua kom cov yeeb yaj kiab txias ceev;

⑤ Tsim nyog txo lub haul-tawm ceev.

Cov yeeb yaj kiab tsis zoo

Kev soj ntsuam ua rau:

1. Tsis tshua muaj extrusion kub, tsis zoo resin plasticization, ua rau tsis zoo pob tshab ntawm zaj duab xis tom qab tshuab molding;

2. Lub tshuab tshuab yog me me dhau;

3. Cov nyhuv txias tsis zoo, yog li cuam tshuam rau qhov pom ntawm cov yeeb yaj kiab;

4. Cov dej noo nyob hauv cov khoom siv raw yog qhov loj heev;

5. Lub traction ceev ceev heev thiab cov yeeb yaj kiab tsis txias txaus.

Kev daws

① Txhim kho qhov kub thiab txias, kom cov resin tuaj yeem ua tau zoo sib xws;

② Tsim nyog nce qhov sib piv;

③ Ua kom cov cua ntim los txhim kho cov nyhuv txias;

③ Ua kom cov huab cua ntim los txhim kho cov nyhuv txias;

④ Qhuav cov khoom siv raw;

⑤ Txo qhov nrawm nrawm kom tsim nyog.

Zaj duab xis wrinkles

Ua rau kev tsom xam

1. Tsis sib xws zaj duab xis thickness;

2. Cov nyhuv txias tsis txaus;

3. Qhov sib piv ntawm lub tshuab yog loj heev, ua rau cov npuas zaj duab xis tsis ruaj khov, ua viav vias rov qab los ntawm ib sab mus rau sab, yog li cov yeeb yaj kiab yuav ua rau wrinkle;

4. Lub kaum sab xis ntawm lub herringbone clamp yog loj heev, cov yeeb yaj kiab npuas yog flattened nyob rau hauv ib tug luv luv deb, yog li cov zaj duab xis kuj yog heev wrinkling;

5. Lub siab ntawm ob sab ntawm cov menyuam traction tsis zoo ib yam, ib sab yog siab thiab lwm sab qis;

6. Lub axes ntawm phau ntawv qhia cov menyuam tsis sib luag, uas cuam tshuam rau kev ruaj ntseg thiab flatness ntawm zaj duab xis, yog li wrinkling tshwm sim.

Kev daws

① Kho qhov tuab ntawm zaj duab xis kom ntseeg tau tias tuab tuab;

② Txhim kho qhov ua kom txias kom ntseeg tau tias cov yeeb yaj kiab tuaj yeem txias tag nrho;

③ Tsim nyog txo cov tshuab tshuab;

③ Txo qhov tshuab kom zoo;

④ Txo lub kaum sab xis ntawm lub herringbone clamp kom tsim nyog;

⑤ Kho lub siab ntawm cov menyuam traction kom ntseeg tau tias cov yeeb yaj kiab raug coj los ua ib qho kev quab yuam;

⑥ Txheeb xyuas cov axis ntawm txhua qhov taw qhia ncej thiab ua rau lawv sib npaug.

Tsis zoo cua sov sealing kev ua tau zoo ntawm zaj duab xis

Ua rau kev tsom xam

1. Frost kab yog tsawg dhau, cov polymer molecules undergo orientation, yog li ua rau cov kev ua tau zoo ntawm cov zaj duab xis nyob ze rau ntawm ib tug oriented zaj duab xis, uas ua rau txo tshav kub sealing kev kawm;

2. Qhov sib piv ntawm lub tshuab thiab traction piv yog qhov loj heev, thiab cov yeeb yaj kiab tau ncav cuag kev taw qhia, yog li cuam tshuam rau lub tshav kub sealing kev ua tau zoo ntawm zaj duab xis.

Kev daws

① Kho qhov loj ntawm cov cua ntim hauv lub nplhaib cua kom cov lwg taw tes siab dua me ntsis, kom deb li deb tau, nyob rau hauv lub melting point ntawm cov yas tshuab thiab traction, thiaj li yuav txo tau cov molecules vim tshuab thiab traction los ntawm stretching orientation;

② Lub tshuab thiab traction ratios yuav tsum me me kom tsim nyog. Yog hais tias qhov sib piv ntawm lub tshuab yog loj heev thiab cov traction ceev ceev heev, cov zaj duab xis yog overstretched nyob rau hauv lub transverse thiab longitudinal cov lus qhia, ces cov kev ua tau zoo ntawm cov zaj duab xis nyhav yuav ob-directionally stretched, thiab zaj duab xis lub tshav kub sealing zog yuav ua tsis zoo.

Zaj duab xis muaj ntxhiab tsw

Ua rau kev tsom xam

1. Cov khoom siv raw khoom nws tus kheej muaj ntxhiab tsw;

2. Lub extrusion kub ntawm cov molten resin yog siab dhau lawm, uas ua rau cov resin decompose, yog li ua rau muaj ntxhiab tsw;

3. Tsis txaus cua txias ntawm zaj duab xis npuas, cua kub hauv cov yeeb yaj kiab npuas tsis raug tshem tawm.

Kev daws

① Hloov cov khoom siv raw;

② Kho qhov kub thiab txias;

③ Txhim kho qhov ua kom txias ntawm lub nplhaib cua txias, kom cov yeeb yaj kiab npuas txaus txias txaus.

Dawb precipitates saum npoo ntawm zaj duab xis

Yog vim li cas: Feem ntau yog additives nyob rau hauv raw cov ntaub ntawv, uas tsis muaj molecular hnyav resins thiab plua plav, thiab lwm yam., uas condense ntawm lub qhov ncauj pwm thaum lub sij hawm ua, thiab tom qab accumulating ib tug tej yam nqi raug tshem tawm los ntawm cov zaj duab xis tsis tu ncua, yog li tsim dawb precipitates rau zaj duab xis.

Kev daws

①Tom qab ib lub sij hawm, ua kom cov ntsia hlau ceev, ua kom cov yaj extrusion siab, tshem tawm cov precipitates.

② Tsis tu ncua ntxuav lub qhov ncauj pwm.

③ Ua kom qhov kub ntawm cov yaj kom tsim nyog kom ua tiav cov yas;

④ SivSILIEK PFAS-dawb PPA masterbatchtuaj yeem txhim kho cov resin ua fluidity, txhim kho kev ua haujlwm sab hauv thiab sab nraud lubrication, txhim kho qhov sib txawv ntawm cov khoom, txo cov agglomeration, txhim kho lub qhov ncauj tuag tsub zuj zuj, thiab tib lub sijhawm tuaj yeem raug coj tawm ntawm lub kaum sab xis ntawm cov khoom siv, yog li txhim kho. qhov zoo ntawm zaj duab xis.SILIEK PFAS-dawb PPA masterbatchyog ib qho kev xaiv zoo tshaj plaws rau fluorinated polymer PPA additives kom tau raws li qhov yuav tsum tau muaj kev txwv fluorine tam sim no.SILIEK PFAS-dawb PPA masterbatchyog ib qho kev hloov zoo meej rau fluorinated polymer PPA additives, uas ua tau raws li cov kev cai ntawm kev txwv fluorine tam sim no.

⑤ Kev sivSILIKE SILIMER series ntawm cov yeeb yaj kiab uas tsis yog nag lossis daus du qhib tus neeg sawv cev, daws cov tsoos tus neeg saib xyuas yog ib qho yooj yim rau precipitate tawm cov hmoov teeb meem.

LDPE zaj duab xis daws teeb meem los txhim kho cov khoom zoo

SILIMER Series Non-Precipitation Film Slip Masterbatchyog ib hom kev hloov kho copolysiloxane uas muaj active organic functional pawg tsim los ntawm Silicone. Cov saw hlau ntev ntev yog sib xws nrog cov resin los ua lub luag haujlwm ntawm kev thauj mus los, thiab cov saw hlau silicon yog polarized rau saum npoo ntawm zaj duab xis los ua lub luag haujlwm ntawm slipperiness, uas tuaj yeem ua lub luag haujlwm ntawm slipperiness yam tsis muaj nag lossis daus.

Ntxiv me me ntawmSILIKE SILIMER 5064MB1, SILIMER 5064MB2thiab lwm cov khoom lag luam tuaj yeem txhim kho cov yeeb yaj kiab zoo, tsis zoo li cov yeeb yaj kiab talc,SILIMER series ntawm cov yeeb yaj kiab uas tsis yog nag lossis daustalc tsis precipitate, tsis poob ntawm cov hmoov, coefficient ntawm kev sib txhuam yog ruaj khov, high-temperature talc tsis lo. Nyob rau tib lub sijhawm tsis cuam tshuam rau kev ua haujlwm tom ntej ntawm zaj duab xis, tsis cuam tshuam rau cov yeeb yaj kiab thaum tshav kub kub sealing kev ua tau zoo, tsis cuam tshuam rau qhov pom ntawm zaj duab xis, tsis cuam tshuam rau kev luam ntawv, laminating thiab lwm yam.
