Cov khoom siv yas

Cov yas feem ntau yog cov khoom khov.Lawv tuaj yeem yog amorphous, crystalline, lossis semi crystalline solids (crystallites).
Cov yas feem ntau yog cov cua sov thiab hluav taws xob tsis zoo.Feem ntau yog dielectrically muaj zog insulators.
Glassy polymers feem ntau yog tawv (xws li, polystyrene).Cov ntawv nyias nyias ntawm cov polymers, ntawm qhov tod tes, tuaj yeem siv ua cov yeeb yaj kiab (xws li, polyethylene).
Thaum muaj kev ntxhov siab, yuav luag tag nrho cov plastics nthuav tawm elongation uas tsis rov qab los tom qab kev ntxhov siab raug tshem tawm.Qhov no yog hu ua "creep."
Plastics feem ntau yog kav ntev thiab degrade ntawm tus nqi qeeb.

Hauv Tsev

Muaj ib qho tseem ceeb ntawm cov yas hauv TV, suab kaw lus, xov tooj ntawm tes, lub tshuab nqus tsev vacuum, thiab feem ntau yuav muaj cov yas ua npuas dej hauv cov rooj tog zaum.Lub rooj zaum yas lossis lub rooj zaum bar, acrylic composite countertops, PTFE linings nyob rau hauv nonstick ua noj pans, thiab cov kav dej yas hauv cov dej.

Automotive thiab Thauj

Plastics tau pab txhawb rau ntau qhov kev tsim kho tshiab hauv kev tsim tsheb, suav nrog kev txhim kho kev nyab xeeb, kev ua tau zoo, thiab kev siv roj.

Cov yas yog siv dav hauv tsheb ciav hlau, dav hlau, tsheb, thiab txawm tias nkoj, satellites, thiab chaw nres tsheb.Bumpers, dashboards, engine Cheebtsam, rooj zaum, thiab qhov rooj tsuas yog ob peb yam piv txwv.

Kev tsim kho

Cov yas tau siv ntau txoj hauv kev hauv kev tsim kho.Lawv muaj cov qib siab ntawm kev siv ntau yam thiab sib xyaw ua ke zoo heev-rau-qhov hnyav piv, durability, nqi-zoo, tsis tshua muaj txij nkawm, thiab corrosion kuj, ua plastics yog ib qho kev xaiv zoo rau kev lag luam hauv kev tsim kho.

  • Cladding thiab Profiles - Cladding thiab profiles rau qhov rais, qhov rooj, npog thiab skirting.
  • Gaskets thiab seals
  • Rwb thaiv tsev

Ntim

Ntau yam yas siv los ntim, xa khoom, khaws cia, thiab ua zaub mov thiab dej haus.Cov yas siv hauv ntim khoom noj tau xaiv rau lawv qhov kev ua tau zoo: lawv tsis muaj zog thiab tshuaj tiv thaiv rau ob qho tib si sab nraud thiab cov khoom noj thiab dej haus lawv tus kheej.

  • Ntau lub thawv yas niaj hnub no thiab cov ntaub qhwv yog tsim tshwj xeeb los tiv thaiv cov cua sov hauv microwave.
  • Ntau lub thawv ntim khoom noj yas muaj qhov txiaj ntsig ntxiv ntawm kev muaj peev xwm hloov pauv ntawm lub freezer mus rau microwave mus rau lub tshuab ntxuav tais diav.

Kev Ua Si Kev Nyab Xeeb Kev Ua Si

  • Cov khoom siv kev nyab xeeb ntawm kev ua kis las yog qhov sib dua thiab muaj zog dua, xws li cov kaus mom yas, lub qhov ncauj tiv thaiv, tsom iav, thiab cov ntaub thaiv npog, kom txhua tus neeg muaj kev nyab xeeb.
  • Moulded, shock-absorbent yas ua npuas ncauj ua rau taw ruaj khov thiab txhawb nqa, thiab cov yas tawv tawv npog cov kaus mom hlau thiab cov ntaub qhwv lub taub hau, pob qij txha, thiab pob txha.

Kev kho mob teb

Cov yas tau siv dav hauv kev tsim cov cuab yeej kho mob thiab cov khoom siv xws li hnab looj tes phais, koob txhaj tshuaj, cwj mem insulin, IV hlab, catheters, inflatable splints, cov hnab ntshav, tubing, tshuab lim ntshav, lub plawv li qub, cov ceg tawv, thiab hnav khaub ncaws, ntawm lwm tus.

Qhov zoo ntawm yas

  • Qhov tseeb txog Plastics
  • Bakelite, thawj cov khoom siv hluavtaws, tau tsim xyoo 1907 los ntawm Leo Baekeland.Tsis tas li ntawd, nws tau sau lo lus "plastics."
  • Lo lus "yas" yog muab los ntawm Greek lo lus plastikos, uas txhais tau hais tias "muaj peev xwm ua tau zoo li qub lossis molded."
  • Ntim nyiaj rau kwv yees li ib feem peb ntawm tag nrho cov yas tsim.Ib feem peb ntawm qhov chaw yog nplooj siab rau siding thiab piping.
  • Feem ntau, cov yas ntshiab yog insoluble hauv dej thiab tsis muaj tshuaj lom.Txawm li cas los xij, ntau cov additives hauv plastics, txawm li cas los xij, yog tshuaj lom thiab tuaj yeem nkag mus rau hauv ib puag ncig.Phthalates yog ib qho piv txwv ntawm cov tshuaj lom neeg ntxiv.Thaum cov polymers uas tsis muaj tshuaj lom yog rhuab, lawv yuav degrade rau hauv tshuaj.
  • Cov lus nug nquag nug txog kev siv cov yas
  • Cov txiaj ntsig thiab qhov tsis zoo ntawm cov yas yog dab tsi?
  • Cov txiaj ntsig thiab qhov tsis zoo ntawm cov yas yog raws li hauv qab no:

Cov txiaj ntsig:

Cov yas yog hloov tau yooj yim dua thiab tsis tshua kim dua cov hlau.
Plastics tsis tshua muaj kev ruaj khov thiab tuaj yeem kav ntev mus ntev.
Kev tsim khoom yas yog nrawm dua li kev tsim hlau.

Qhov tsis zoo:

  • Lub ntuj decomposition ntawm plastics yuav siv sij hawm 400 mus rau 1000 xyoo, thiab tsuas yog ob peb hom yas yog biodegradable.
  • Cov ntaub ntawv yas ua rau lub cev dej tsis zoo xws li dej hiav txwv, hiav txwv, thiab pas dej, tua tsiaj hauv hiav txwv.
  • Nyob rau tib lub sij hawm, ntau tus tsiaj noj cov khoom yas thiab tuag vim li ntawd.
  • Kev tsim khoom yas thiab rov siv dua ob qho tib si tso tawm cov pa phem thiab cov khoom seem uas ua rau huab cua, dej, thiab av.
  • Qhov twg yog cov yas siv ntau tshaj?
  • Txhua xyoo, ntau tshaj 70 lab tonnes ntawm thermoplastics yog siv rau hauv textiles, feem ntau hauv khaub ncaws thiab ntaub pua plag.

Cov yas ua lub luag haujlwm dab tsi hauv kev lag luam?

Yas muaj ntau qhov txiaj ntsig ncaj qha rau kev lag luam thiab tuaj yeem pab nrog kev ua haujlwm zoo.Nws txo cov khoom pov tseg los ntawm kev ncua lub txee lub neej ntawm cov zaub mov, thiab nws lub teeb yuag txo cov roj noj thaum thauj khoom.

Vim li cas peb yuav tsum nyob deb ntawm cov yas?

Cov yas yuav tsum raug zam vim lawv tsis yog biodegradable.Lawv siv sij hawm ntau xyoo los decompose tom qab nkag mus rau hauv ib puag ncig.Plastics ua paug rau ib puag ncig.
