Polyethylene Terephthalate yog dab tsi thiab nws siv rau dab tsi?

1. Lub ntsiab lus ntawm PET

Polyethylene terephthalate(PETE lossis PET) yog cov thermoplastic polymer feem ntau siv hauv ntiaj teb thiab paub zoo dua hauv kev lag luam textile los ntawm lub npe lag luam "polyester." Nws yog ib qho pob tshab thiab semi-crystalline yas dav siv los ua fiber ntau rau cov khaub ncaws, raws li kev tiv thaiv dej noo zoo nrog kev siv dav hauv bottling thiab ntim khoom (paub nyob rau hauv cov ntaub ntawv no li PET lossis "PET resin"), thiab raws li cov yas yas thaum nws tau ua ke nrog lwm cov ntaub ntawv xws li iav fiber ntau los yog carbon nanotubes kom nce cov khoom siv zog. Nws yog ib yam khoom uas tsis muaj xim, semi-crystalline. Qee yam ntawm nws cov yam ntxwv tseem ceeb tshaj plaws suav nrog nws cov dej tsis kam, nws lub zog siab rau qhov hnyav piv, qhov tseeb tias nws yog qhov tsis zoo (nws yuav tsis tawg zoo li lub khob ntim), thiab nws muaj dav dav raws li kev lag luam thiab cov yas rov ua dua tshiab (cov ntaub ntawv txheeb xyuas. code "1").

 

PET yog thawj polymerized nyob rau hauv 1940s los ntawm DuPont chemists tab tom nrhiav los tsim cov ntaub ntawv polymer rau siv ua textile fibers. Nws yog tsim los ntawm kev sib txuas ntawm ethylene glycol thiab terephthalic acid. Txawm tias tsis muaj tshuaj ntxiv los ua kom nws lub zog, PET tseem muaj zog heev rau nws lub teeb yuag. Qhov no txhais tau hais tias yuav tsum muaj cov khoom siv tsawg dua rau kev siv xws li yas zaj duab xis rau ntim. Qhov no txhais tau tias tsawg dua roj yuav tsum tau rau shipping thaum siv PET ntim. Tsis tas li ntawd, txawm hais tias cov khoom siv yog roj av, kwv yees li 40% ntawm lub zog yog khaws cia rau hauv thiab muaj nyob rau zaum ob thaum rov ua dua. Raws li PETresin.org, "Kev tshawb fawb txog lub neej ntawm PET tau pom tsis tu ncua nws yog cov khoom siv muaj txiaj ntsig zoo nrog rau qhov zoo.

Raws li qee cov lus ceeb toom, qhov kev thov thoob ntiaj teb tam sim no rau cov khoom tsim ua lag luam txhua xyoo txog li 56 lab metric tons. Cov neeg siv khoom loj kawg ntawm polypropylene yog kev lag luam textile, uas (raws li Wikipedia) siv li 60% ntawm tag nrho. Lwm qhov kev siv tseem ceeb suav nrog lub raj mis thiab ntim kev lag luam uas suav txog kwv yees li 30%.

 

2. Cov yam ntxwv ntawm Polyethylene terephthalate yog dab tsi?

Qee qhov tseem ceeb tshaj plaws ntawm Polyethylene terephthalate (PETE lossis PET) yog:

Tshuaj Resistance: PET tsis hnov ​​​​mob nrog dej lossis zaub mov uas yog ib qho laj thawj uas nws siv rau kev ntim khoom.

Strength to Weight Ratio: PET muaj zog heev rau nws qhov hnyav.

Shatterproof: PET yuav tsis tawg lossis tawg. Qhov no ua rau nws hloov tau zoo rau iav ua lub thawv.

Transmissivity: Polyethylene terephthalate (PETE lossis PET) yog pob tshab. Uas tau hais tias, yog tias xav tau siab transmissivity ces cov yas xws li Acrylic lossis Polycarbonate yuav yog qhov kev xaiv zoo dua.

 

3. Qhov Zoo ntawm Polyethylene terephthalate yog dab tsi?

Polyethylene terephthalateyog yooj yim muaj thiab kuj pheej yig.

Polyethylene terephthalate muaj lub zog siab rau qhov hnyav piv.

Polyethylene terephthalate (PET) yog resistant rau ya raws.

Polyethylene terephthalate muaj cov tshuaj tiv thaiv zoo rau cov khoom siv organic thiab dej (nws tsis yog biodegradable uas yog qhov zoo thiab tsis zoo nyob ntawm koj qhov kev xav thiab nws txoj kev siv).

Polyethylene terephthalate yog zoo li shatterproof (nws yuav tsis tawg zoo li iav ntim).

Polyethylene terephthalate tau yooj yim siv dua. Nws tuaj yeem rov qab siv tau los ntawm kev ua cov txheej txheem ntxuav los yog tawg rau hauv nws cov khoom siv raw uas tuaj yeem hloov mus rau hauv cov khoom qub.

Polyethylene terephthalate yog pob tshab heev.
