Qhov cuam tshuam ntawm Pe Khoom Hauv Cov Khoom Siv Hnab Ntim

Qhov nrov ntawm PE raw cov ntaub ntawv nyob rau hauv ntim hnab raw khoom!PE raw khoom yog qhov tseem ceeb hauv kev ntim khoom.Yog tias koj xav kaw lub hnab ntim khoom, PE yuav tsum muab ntxiv rau cov khoom siv raw.Nws mus yam tsis tau hais tias PE raw khoom yog tus yuam sij!Qhov nrov ntawm PE raw khoom hauv ntim:

1. General PE raw khoom yam ntxwv piav qhia:

Feem ntau, cov tsos ntawm PE raw khoom ntim lub hnab yog pob tshab, tab sis nws muaj pos huab;nws yog mos rau qhov kov thiab muaj ductility zoo;Tsis tshua muaj kub tsis kam thiab muaj zog dej tsis kam, tab sis piv nrog O2, cov roj barrier yog tsawg;Los yog daws, tuaj yeem luam thev naus laus zis lub teeb grey, tsis pom zoo rau qhov loj-scale tsaus kas fes luam ntawv ntim.

2. Kev faib cov khoom siv raw ntawm PE ntim hnab hauv cov ntim khoom:

PE txheej txheem ntau lawm, PE tuaj yeem muab faib ua peb pawg: HDPE.HDPE muaj tsawg ntom ntom, LDPE muaj tsawg ntom ntom, linear txheeb ze ceev yog tsawg, thiab LLDPE yog tsawg.Lawv daim ntawv thov tsom rau hauv cov hnab ntim khoom sib txawv, thiab lawv cov yam ntxwv kuj txawv.HDPE raw khoom muaj qhov sib txheeb siab ntom ntom, tseem hu ua low-voltage high-voltage polyethylene, thiab muaj qhov kub thiab txias tsis kam, kub tsis kam, acid thiab alkali tsis kam thiab lwm yam ntxwv.pob tshab txheej.

LDPE raw khoom nrog qhov ntom ntom kuj tseem hu ua polyethylene, uas yog cov khoom siv softer PE.Cocoa tuaj yeem siv ncaj qha los ua lub hnab ntim khoom, xws li lub hnab thauj khoom rau cov txiv hmab txiv ntoo tshiab, nqaij thiab lwm yam khoom noj khoom haus khov.Los yog hnab yas, hnab zaj duab xis, thiab lwm yam rau kev yuav khoom noj.

LLDPE raw cov ntaub ntawv uas tsis tshua muaj linear ceev: zoo ib yam li LDPE, tsis tshua muaj kub ductility, cuam tshuam tsis kam, kev nyuaj siab teb cracking kuj, qaug zog kuj, tus yam ntxwv no kuj zoo.Siv LLDPE thawj ice cream, ice cream, meatballs, ceev-frozen dumplings thiab lwm yam ntim hnab, thiab siv cov tshav kub nkag txheej ntawm LLDPE raw cov ntaub ntawv.

3. Txoj kev sib txawv ntawm cov hnab ntim khoom ntim nrog cov khoom siv PE raw khoom thiab qhov ntom ntom ntawm PE:

1. Yog tias txhais tes yog mos, nws tuaj yeem ua softer, thiab cov khoom uas muaj qhov ntom ntom yog softer.

2. Thaum khawb cov khoom nyoos nrog rau cov ntiv tes, nws tsis yooj yim kom tawm khawb.Nws yog HDPE cov khoom siv raw, HDPE nrog cov txheeb ze siab, thiab LDPE nrog cov txheeb ze tsawg.
