Qhov twg zoo dua PEVA lossis yas?
Taw qhia:
Thaum nws los txog rau kev xaiv cov khoom siv rau ntau yam kev siv, nws yog ib qho tseem ceeb kom nkag siab txog qhov sib txawv thiab cov yam ntxwv ntawm txhua qhov kev xaiv. Hauv tsab xov xwm no, peb yuav delve rau hauv kev sib cav ntawm PEVA vs. yas thiab tshawb txog lawv cov khoom, kev siv, qhov zoo, thiab kev txwv. Thaum kawg, koj yuav tau nruab nrog kev paub los txiav txim siab seb cov khoom twg zoo dua rau koj cov kev xav tau tshwj xeeb.
Nkag siab PEVA thiab vinyl:
Ua ntej peb piv PEVA thiab yas, cia peb pib los ntawm kev nkag siab tias txhua yam khoom yog dab tsi.
*1. PEB:*
PEVA, lossis Polyethylene Vinyl Acetate, yog cov khoom siv tsis muaj chlorinated vinyl. Nws yog ib qho thermoplastic polymer uas yog mos, hloov tau, thiab tiv taus dej. PEVA yog dav siv los hloov PVC (Polyvinyl Chloride) vim nws qhov cuam tshuam ib puag ncig qis. Nws paub tias tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab tsis muaj tshuaj lom neeg xws li chlorine thiab phthalates.
*2. Vinyl:*
Vinyl, tseem hu ua PVC, yog cov khoom siv hluavtaws polymer ua los ntawm cov yas chloride monomers. Nws yog ruaj, dej-resistant, thiab muaj tshuaj lom neeg zoo heev. Vinyl yog dav siv nyob rau hauv ntau yam lag luam vim nws versatility thiab nqi-zoo. Txawm li cas los xij, nws tsim nyog sau cia tias cov khoom siv yas tsoos suav nrog kev siv tshuaj chlorine, uas ua rau muaj kev txhawj xeeb txog ib puag ncig.
Sib piv cov khoom:
Txhawm rau txiav txim siab yam khoom twg zoo dua, cia peb sib piv lawv cov khoom:
*1. Waterproofness: *
Ob leeg PEVA thiab vinyl muab cov khoom siv dej tsis zoo. Lawv muaj peev xwm tiv taus dej thiab tuaj yeem tiv thaiv qhov chaw hauv qab lossis cov khoom lag luam zoo los ntawm kev puas tsuaj los ntawm kev ya raws.
*2. Durability: *
Vinyl feem ntau ruaj dua PEVA. Nws muaj kev tiv thaiv ntau dua rau tearing, pncturing, thiab puas. Qhov no ua rau vinyl yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau cov khoom siv ntev thiab muaj zog.
Ntawm qhov tod tes, PEVA yog softer thiab hloov tau. Txawm hais tias nws yuav tsis tshua muaj zog dua li yas, nws muaj kev tiv thaiv zoo rau hnav thiab tsim kua muag.
*3. Tshuaj tiv thaiv: *
Vinyl nthuav tawm cov tshuaj tiv thaiv zoo dua piv rau PEVA. Nws tuaj yeem tiv taus ntau yam tshuaj, roj, thiab cov kuab tshuaj yam tsis muaj kev puas tsuaj loj. Cov cuab yeej no ua rau vinyl qhov kev xaiv tsim nyog rau cov ntawv thov uas muaj kev sib cuag nrog cov khoom muaj txiaj ntsig zoo.
PEVA, txawm hais tias resistant rau qee cov tshuaj, yuav tsis muaj tib theem ntawm kev tiv thaiv li yas. Nws yog ib qho tseem ceeb uas yuav tsum xav txog cov tshuaj tshwj xeeb lossis cov khoom siv uas cov khoom yuav tuaj yeem sib cuag nrog thaum xaiv ntawm PEVA thiab yas.
*4. Environmental cuam tshuam:*
Ib qho txiaj ntsig tseem ceeb ntawm PEVA tshaj li yas yog nws qhov kev cuam tshuam ib puag ncig qis. PEVA tsis muaj tshuaj chlorine thiab tsis muaj phthalates teeb meem, ua rau nws muaj kev xaiv zoo dua. Tsis tas li ntawd, cov txheej txheem tsim khoom ntawm PEVA emits tsawg dua cov tshuaj lom byproducts piv rau cov tsoos yas ntau lawm.
Vinyl, raws li tau hais ua ntej, ua rau muaj kev txhawj xeeb ntawm ib puag ncig vim kev siv cov tshuaj chlorine thiab muaj peev xwm tso tawm cov tshuaj phem thaum nws tsim khoom thiab decomposition.
*5. Tsis muaj ntxhiab thiab tsis muaj tshuaj lom: *
Ob leeg PEVA thiab vinyl feem ntau suav hais tias tsis muaj ntxhiab thiab tsis muaj tshuaj lom. Txawm li cas los xij, nws yog ib qho tseem ceeb los xyuas kom meej tias cov khoom tshwj xeeb lossis cov khoom tsim los ntawm cov ntaub ntawv no ua raws li cov qauv kev nyab xeeb thiab cov cai.
