Cov yam ntxwv ntawm Polypropylene (PP) yog dab tsi?
Qee qhov tseem ceeb tshaj plaws ntawm polypropylene yog: 1. Kev Tiv Thaiv Tshuaj: Cov hauv paus diluted thiab cov kua qaub tsis yooj yim teb nrog polypropylene, uas ua rau nws yog qhov kev xaiv zoo rau cov thawv ntawm cov kua xws li, xws li cov neeg ua haujlwm ntxuav, cov khoom siv kho mob thawj zaug, thiab ntau ntxiv. 2. Kev ywj pheej thiab Kev tawv: Polypropylene yuav ua haujlwm nrog elasticity dhau qee qhov kev hloov pauv (zoo li txhua yam khoom siv), tab sis nws tseem yuav ntsib kev hloov pauv yas thaum ntxov hauv cov txheej txheem hloov pauv, yog li nws feem ntau suav hais tias yog cov khoom siv "tawv". Kev tawv yog ib lo lus engineering uas txhais tau tias yog cov khoom siv lub peev xwm los hloov pauv (plastically, tsis yog elastically) yam tsis tawg .. 3. Kev Tiv Thaiv Kev Qaug Zog: Polypropylene khaws nws cov duab tom qab ntau torsion, khoov, thiab / lossis flexing. Cov khoom no yog e ... -
Cov ntaub ntawv vaj tse raug tshem tawm tsis zoo, thiab PVC raug ua kom sib dua.
Hnub Monday, cov ntaub ntawv vaj tse tseem qeeb qeeb, uas muaj kev cuam tshuam tsis zoo rau kev cia siab ntawm kev thov. Raws li qhov kaw, daim ntawv cog lus PVC tseem ceeb poob ntau dua 2%. Lub lim tiam dhau los, cov ntaub ntawv CPI hauv Tebchaws Meskas thaum Lub Xya Hli qis dua qhov xav tau, uas ua rau cov tub ua lag luam muaj kev pheej hmoo ntau ntxiv. Tib lub sijhawm, qhov kev thov kub, cuaj lub nyiaj thiab kaum lub caij siab tshaj plaws tau xav tias yuav zoo dua, uas tau muab kev txhawb nqa rau tus nqi. Txawm li cas los xij, kev ua lag luam muaj kev tsis ntseeg txog kev ruaj khov rov qab los ntawm sab kev thov.

HDPE siv rau dab tsi?
HDPE siv rau hauv cov khoom thiab cov ntim khoom xws li cov khob mis nyuj, cov fwj tshuaj ntxuav tes, cov thoob margarine, cov thawv pov tseg thiab cov kav dej. Hauv cov raj uas muaj ntau qhov ntev sib txawv, HDPE siv los hloov cov raj xa ntawv cardboard mortar rau ob qho laj thawj tseem ceeb. Ib qho, nws muaj kev nyab xeeb dua li cov raj xa ntawv cardboard vim tias yog tias lub plhaub ua haujlwm tsis zoo thiab tawg hauv cov raj HDPE, lub raj yuav tsis tawg. Qhov laj thawj thib ob yog tias lawv siv tau dua uas tso cai rau cov neeg tsim qauv tsim ntau lub txee mortar. Cov kws kho phom tsis pom zoo siv cov raj PVC hauv cov raj xa ntawv mortar vim tias nws feem ntau tawg, xa cov yas me me rau cov neeg saib, thiab yuav tsis tshwm sim hauv X-rays. -
Daim npav ntsuab PLA dhau los ua qhov kev daws teeb meem nrov rau kev lag luam nyiaj txiag.
Txhua xyoo xav tau yas ntau dhau los ua daim npav rho nyiaj, thiab nrog kev txhawj xeeb txog ib puag ncig loj hlob tuaj, Thales, tus thawj coj hauv kev ruaj ntseg thev naus laus zis siab, tau tsim ib qho kev daws teeb meem. Piv txwv li, daim npav ua los ntawm 85% polylactic acid (PLA), uas yog los ntawm pob kws; lwm txoj hauv kev tshiab yog siv cov ntaub so ntswg los ntawm kev ua haujlwm ntxuav ntug dej hiav txwv los ntawm kev koom tes nrog pawg ib puag ncig Parley rau Oceans. Cov khib nyiab yas sau - "Ocean Plastic®" ua cov khoom siv tshiab rau kev tsim cov npav; kuj tseem muaj kev xaiv rau cov npav PVC rov ua dua tshiab ua los ntawm cov yas pov tseg los ntawm kev lag luam ntim khoom thiab luam ntawv kom txo qis kev siv cov yas tshiab. -
Kev tshuaj xyuas luv luv ntawm Tuam Tshoj cov ntaub ntawv xa tawm thiab xa tawm ntawm pvc resin paste txij lub Ib Hlis mus txog rau Lub Rau Hli.
Txij lub Ib Hlis mus txog rau Lub Rau Hli 2022, kuv lub teb chaws tau xa tawm tag nrho 37,600 tons ntawm cov tshuaj nplaum, txo qis 23% piv rau lub sijhawm tib yam xyoo tas los, thiab xa tawm tag nrho 46,800 tons ntawm cov tshuaj nplaum, nce 53.16% piv rau lub sijhawm tib yam xyoo tas los.

Polypropylene (PP) yog dab tsi?
Polypropylene (PP) yog ib yam khoom siv thermoplastic uas tawv, tawv, thiab siv lead ua. Nws yog ua los ntawm propene (lossis propylene) monomer. Cov roj hydrocarbon linear no yog cov polymer sib dua ntawm txhua yam khoom yas. PP los ua homopolymer lossis copolymer thiab tuaj yeem ua kom muaj zog nrog cov khoom ntxiv. Nws pom daim ntawv thov hauv kev ntim khoom, tsheb, khoom siv rau cov neeg siv khoom, kev kho mob, cov yeeb yaj kiab cam khwb cia, thiab lwm yam. PP tau dhau los ua cov khoom siv xaiv, tshwj xeeb tshaj yog thaum koj tab tom nrhiav cov polymer uas muaj zog dua (piv txwv li, vs Polyamide) hauv kev siv engineering lossis tsuas yog nrhiav qhov zoo dua hauv cov fwj tshuab (vs. PET).
