Foamed polyethylene. Hais txog cov yam ntxwv ntawm cov khoom

Tsis li ntawd, ntev dhau los nyob rau hauv lub domestic kev ua lag luam ntawm lub ntim ntaub ntawv xws li yuav pom tus tshiab cov ntaub ntawv uas - polyethylene ua npuas ncauj. Nws muaj cim kev kawm yam ntxwv uas tau tso cai rau nws mus ua heev nrov ntim khoom. Nws twb nyob li cov tub txawg ntawm qhov kev siv ua lag ua luam, thiab zoo tib yam cov kiv cua.

Yuav ua li cas yog nws nyiam?

Polyethylene yog xws li ib tug pab pawg neeg copes nrog nws zog raws li ib tug cushioning thiab ntim khoom. Feem ntau, cov kev tso cai uas tsim nyog nyob rau hauv tej qhov chaw hauv lub tsheb thauj mus los ntawm cov khoom yog tom. Lub foamed polyethylene qhia ntxiv kev tiv thaiv rau cov cargo los ntawm cov av, noo noo, thiab cov neeg kho tshuab kev puas tsuaj xwm. Nrog rau nws ntau heev siv cua-npuas zaj duab xis, lug txhim khu kev tiv thaiv, thaum nws yog tiag tiag uas yuav tsum tau.

Nta ntawm cov khoom thiab nws cov variants

Rau ib cov ntaub ntawv uas xws li foamed polyethylene, ncaav tau cov pa polymerization ntawm ethylene. Raws li ib tug tshwm sim ntawm txoj kev ua no, cov khoom ua ib crystallizes. Qhov no yog vim lub tshaaj ntawm xws li ib tug qauv khoom khaws noo noo txawm nyob rau hauv 130 degrees, thiab ntau ntse thaum nws tej yam los ntawm cov ib puag ncig.

Hom ntawm cov ntaub ntawv uas lub zog

Lub cev crosslinked thiab sib crosslinked - nyob rau hauv no embodiment, foamed polyethylene yog nyob rau hauv lub lag luam niaj hnub no. Thaum nws los txog rau lub ntim, muaj ib tug siab yuav qhov muaj tseeb nws yuav tsum yog ib tug polyethylene crosslinked lub cev. Cov kab kev los ntawm thickness ntawm no tsiaj yuav thaj tsam li ntawm tsib mus rau nees nkaum-kaum ntawm millimeters. Txawm tias variations nyob rau hauv ceev tseem me me. Yog li ntawd hais tias txhua tus neeg muaj peev xwm ua tus tswv ntawm lub zoo ntim uas fulfills cov kev uas yuav tsum tau ntawm tus neeg.

Nyob rau salient nta

Muaj ib tug xov tooj ntawm cov yam ntxwv uas muab koob meej ntawm tej khoom raws li polyethylene ua npuas ncauj. Nqe khoom yog nyob ntawm seb zoo. Yog li, tus yam ntxwv ntawm:

• tsis yog ib qho allergen, muaj kev ruaj ntseg los ntawm ib tug tej taw tes ntawm view;
• hnav tsis kam thiab durability;
• insensitivity kub hloov;
• tsawg abrasiveness;
• zoo heev poob siab absorbing cov khoom;
• seem stability;
• me me thermal conductivity;
• dej kuj;
• yooj thiab elasticity.

Tej ntaub ntawv uas nas tsuag thiab kab tsis ua kom muaj kev raug mob. Pwm, pwm thiab tshuaj los yog tsis txaus ntshai, ib yam nkaus thiab. Lub kaw cell qauv - ib yam ntawm cov yam ntxwv tseem ceeb ntawm tej khoom raws li polyethylene ua npuas ncauj. Lub thickness ntawm cov khoom muaj suab tsis ntxim rau nws zoo heev muaj peev xwm los ua ib tug zoo insulator thiab muaj peev xwm tsis mus dhau dej thiab chav, txawm nyob rau hauv loj qhov ntau. Yog hais tias lub chaw thau khoom nto los yog nyob qhov twg nyob ze ntawm lub thoob khib nyiab tau txais kev, nws yog polyethylene ua npuas ncauj yuav coj qhov teeb meem rau nws tus kheej. Vim hais tias cov khoom nws tus kheej yog tsis raug rau cov neeg kho tshuab kev puas tsuaj.
