Feem ntau cov yeeb yaj kiab LDPE yog ua los ntawm ob qho tib si tshuab molding thiab casting txheej txheem. Cast polyethylene zaj duab xis muaj ib tug tuab sib npaug, tab sis tsis tshua siv vim nws tus nqi siab. Blown polyethylene zaj duab xis yog ua los ntawm blow-molded qib PE pellets los ntawm cov tshuab blow-molding, uas yog qhov siv dav tshaj plaws vim nws tus nqi qis dua.

Cov yeeb yaj kiab polyethylene uas tsis muaj zog yog cov yeeb yaj kiab uas muaj cov duab pob tshab, ci ntsa iab, thiab mos mos, thiab muaj kev ruaj khov zoo heev, ua kom sov tau zoo, tiv taus dej thiab noo noo, thiab khov tau, thiab nws kuj siv tau rau hauv dej npau. Qhov tsis zoo ntawm cov yeeb yaj kiab no yog qhov tsis zoo rau cov pa oxygen, feem ntau siv rau hauv cov khoom ntim khoom sib xyaw ua ke, uas yog txheej sab hauv ntawm cov yeeb yaj kiab, thiab tam sim no kuj yog cov yeeb yaj kiab yas uas siv ntau tshaj plaws, uas yog cov yas ntim khoom loj tshaj plaws, suav txog ntau dua 40% ntawm cov yas ntim khoom siv.

Vim tias cov polyethylene molecule tsis muaj cov pab pawg polar thiab muaj qib siab ntawm crystallinity thiab qis qhov chaw dawb zog, zaj duab xis muaj cov khoom luam ntawv tsis zoo thiab tsis nplaum rau cov kua mem thiab cov nplaum, yog li kev kho qhov chaw yog qhov yuav tsum tau ua ntej luam ntawv thiab laminating.

Cov hauv qab no yog cov kev ua tsis tiav thiab cov kev daws teeb meem rau LDPE blown zaj duab xis:

Zaj duab xis nplaum dhau, tsis qhib tau yooj yim

Kev tshuaj xyuas ua rau:

1. Cov khoom siv raw resin tsis yog hom zoo, tsis yog blown zaj duab xis qib LDPE resin, uas tsis muaj tus neeg sawv cev qhib lossis tus neeg sawv cev qhib tsis zoo;

2. Qhov kub ntawm cov roj hmab molten siab dhau, qhov fluidity loj dhau;

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

4. Qhov ceev txias qeeb dhau, zaj duab xis tsis txias txaus, thiab kev sib txuas ua ke tshwm sim nyob rau hauv qhov kev ua ntawm lub zog rub rub;

5. Qhov ceev ntawm lub traction yog ceev dhau.

Cov Kev Daws Teeb Meem

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

⑤ Txo qhov ceev ntawm kev thauj khoom kom haum.

Zaj duab xis wrinkles

Kev tshuaj xyuas qhov ua rau

1. Cov zaj duab xis tsis sib xws;

2. Cov nyhuv txias tsis txaus;

3. Qhov piv ntawm lub tshuab loj dhau, ua rau lub npuas zaj duab xis tsis ruaj khov, viav vias rov qab los ntawm ib sab mus rau ib sab, yog li zaj duab xis yuav yooj yim ntsws;

4. Lub kaum sab xis ntawm lub clamp herringbone loj dhau, lub npuas zaj duab xis tau flattened nyob rau hauv ib qho luv luv deb, yog li zaj duab xis kuj yog ib qho yooj yim rau wrinkling;

5. Lub siab ntawm ob sab ntawm lub traction roller tsis sib xws, ib sab siab thiab sab tod qis;

6. Cov axes ntawm cov menyuam qhia kev tsis sib luag, uas cuam tshuam rau kev ruaj khov thiab kev tiaj tus ntawm zaj duab xis, yog li ntawd wrinkling tshwm sim.

Kev daws teeb meem

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

② Txhim kho qhov txias kom ntseeg tau tias zaj duab xis tuaj yeem txias tag nrho;

③ Txo qhov sib piv ntawm cov tshuab kom tsim nyog;

③ Txo qhov sib piv ntawm cov tshuab kom haum;

④ Txo lub kaum sab xis ntawm lub clamp herringbone kom haum;

⑤ Kho qhov siab ntawm lub traction roller kom ntseeg tau tias zaj duab xis raug rau lub zog sib xws;

⑥ Xyuas lub axis ntawm txhua tus ncej qhia thiab ua kom lawv sib luag.

Kev ua haujlwm tsis zoo ntawm cov yeeb yaj kiab

Kev tshuaj xyuas qhov ua rau

1. Cov kab te qis dhau, cov polymer molecules raug kev taw qhia, yog li ua rau kev ua yeeb yam ntawm zaj duab xis ze rau ntawm zaj duab xis taw qhia, ua rau kev ua haujlwm kub qis dua;

2. Qhov piv ntawm lub tshuab thiab qhov sib piv ntawm lub zog rub loj dhau, thiab zaj duab xis no raug ncab mus rau qhov kev taw qhia, yog li cuam tshuam rau kev ua haujlwm ntawm lub cua sov ntawm zaj duab xis.

Kev daws teeb meem

① Kho qhov loj ntawm lub cua ntim hauv lub nplhaib cua kom ua rau cov dej noo siab me ntsis, kom deb li deb tau, nyob rau hauv qhov chaw yaj ntawm cov yas tshuab thiab traction, txhawm rau txo cov molecules vim yog tshuab thiab traction los ntawm kev ncab orientation;

② Qhov piv ntawm kev tshuab thiab kev rub yuav tsum me me. Yog tias qhov piv ntawm kev tshuab loj dhau thiab qhov ceev ntawm kev rub ceev dhau, zaj duab xis yuav ncab ntau dhau hauv cov lus qhia transverse thiab longitudinal, ces qhov kev ua tau zoo ntawm zaj duab xis feem ntau yuav ncab ob sab, thiab cov khoom siv kaw cua sov ntawm zaj duab xis yuav tsis zoo.

Zaj duab xis muaj ntxhiab tsw

Kev tshuaj xyuas qhov ua rau

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

2. Qhov kub ntawm cov roj hmab uas yaj dhau lawm, ua rau cov roj hmab lwj, ua rau muaj ntxhiab tsw phem;

3. Tsis txias txaus ntawm lub npuas zaj duab xis, cua kub hauv lub npuas zaj duab xis tsis raug tshem tawm.

Kev daws teeb meem

①Hloov cov khoom siv raw resin;

② Kho qhov kub ntawm extrusion;
