Dab tsi yog qhov taw tes siv lead ua ntawm zaj duab xis tshuab tshuab

Crystal point yog tshwm sim los ntawm unplasticized polymer hais nyob rau hauv lub tshuab cua tshuab, thiab lub molecular luj ntawm lub crystal point yog ntau dua li qhov hnyav molecular ntawm ib puag ncig PE.

① Cov khoom siv raw khoom tsis yog tswj nruj heev hauv cov txheej txheem tsim khoom, ua rau ib feem ntawm cov khoom hnyav molecular ntawm cov resin siab dhau lawm, thiab cov khoom tsis tuaj yeem ua plasticized.

② Muaj ntau cov khoom seem seem hauv cov khoom siv raw, thiab ntawm qhov kub ntawm lub tog raj kheej ntsia hlau ntawm lub tshuab tshuab tshuab, cov catalyst txuas ntxiv ua thiab tsim cov qib siab ntawm polymerization molecule, yog li ntawd, xaiv cov ntaub ntawv raw yog heev. tseem ceeb.

Tom qab tshuab zaj duab xis, txiav tawm lub hnab tsho khuam.
Cov khoom yas yog plasticized los ntawm extruder thiab ces tshuab mus rau hauv ib zaj duab xis los ntawm zaj duab xis tshuab tshuab. Lub thawv zaj duab xis yog txiav rau hauv cov duab uas xav tau los ntawm lub tsho khuam lub hnab ua tshuab, thiab hauv qab yog kub-sealed.
Cov txheej txheem yog yooj yim, muaj cov cav tov sib xws.
