VAE Emulsion rau hauv Lub Tsev Nyiam Xeeb Nyiam: Ib Qho Kev Los Txuag Kev Nyab Xeeb

Kev paub txog VAE Emulsion thiab nws qhov ua haujlwm rau hauv kev tsim kho tseeb

Qhov chaw tsim kho tsev hauv plhaug ntawm lub teb chaws tuaj yeem los ntawm kev hla phau duab rau cov khoom siv tshuaj ntsuab tshiab, ua rau VAE emulsion tau zwm sab hauv kev tsim kho tsev nyob qhov twg. Txhawj xeeb tias nyob ib leeg no, muaj ib cheem tob kawg ntawm cov neeg tsim khoom tau coj mus siv cov khoom siv tshuaj ntsuab tshiab uas muaj VAE copolymer emulsions. Qhov kev pib no yog ib qho yooj yim vim tias peb pom cov luj lawm kev ruaj ntseg thiab cov kev txwv txwm zoo li LEED. Lub tsev neeg kho tsev tshuaj txaus sawv ceem tau hais txog qhov kev pib no nyob rau hlis 2023, sau tseg tias cov chaw tsim khoom tau hloov txoj kev ua siab kom raug thiab kom txo qhov kev puas tsuaj rau dej num av.

VAE Copolymer Emulsion yog dab tsi thiab nws cov caij nyoog?

VAE, u siv npe no rau vinyl acetate ethylene copolymer emulsion, yog li ib qhov adhesive polymer uas tshuaj kub rau cov khoom siv hluas. Nws muaj zog siab, tsim nyog rau kev sib txuas thiab tso tseg rau kev tawm tsam ntawm dej. Qhov uas pab VAE zoo dua yog vim nws sib cuag ntawm vinyl acetate thiab ethylene ntawm molecular level. Qhov no tsim tau ib qhov binding agent uas pab tsoom phooj ywg ntau dua tsis txhob ua rau tshwm sim kev puas tsuaj rau dej num. Yog mloog saib VAE sib txawv li cas los ntawm lwm hom glue. Thaum pib, nws tsis muaj cheeb looj li lwm yam khoom siv. Thaum ob, nws ua haujlwm zoo nrog cov khoom siv recycled uas ntau tus neeg tsim khoom xav siv tam sim no. Thaum ci, tsis muaj formaldehyde tawm los ntawm nws. Qhov thaum ci no yog ib qhov tseem ceeb heev kom rau sawv daws solvent based adhesives uas tuaj yeem tso cov khoom siv noj mov tawm hauv av.

Kev Txawj ntse plua pluaj los ntawm Solvent-Based mus rau Water-Based Formulations hauv Green Building

Hnag tshuab ua haujlwm los ntawm kev siv cov neeg ua ke siv cov nta loj li 40% thaum puv xyoo 2020 raws li cov nta ntawv ntawv los ntawm Global Green Chemistry Initiative xyoo thaum ntawm. Qhov kev hloov pauv no los thaum lawv ua haujlwm ntau dua thiab tib neeg pib xav txog yav li cas lawv siv rau hauv qhov chaw uas lawv nyob. Cov neeg ua ke ua haujlwm hauv dej VAE yuav raug siv ntau dua vim tias lawv tiv thaiv cov neeg ua ke siv cov nta uas ua rau cov dej hauv ntim ua rau kev nyob zoo. Cov khoom tshiab no pab tiv thaiv cov teeb meem hauv ntim dej thaum kuj pab ua haujlwm zoo li qhov xav tau. Ntau lub teb chaw ua rau cov khoom zoo hauv ntim ntawv tsim nyog tau xav txog cov khoom siv uas tuaj yeem txhais tau tias lawv zoo hauv txhua qhov kev ua haujlwm los ntawm kev tsim khoom mus rau kev tshem tawm.

Yuav ua li cas Low-VOC VAE Emulsions pab kev tsim khoom uas zoo rau kev nyob hauv ntim

VAE emulsions tsawg VOC cuam tiv thaiv kev nyuaj siab rau kev lag luam thiab pab kom ua raws li lwm yam uas tswj hwm kev lag luam. Lawv cov yooj yim ua rau dej pab ua kom ua siab ntau dua rau cov ntaub ntawv tsim tawm, tiv thaiv ntau tshaj 30% cov ntaub uas nyob hauv cov nplaw thiab cov ntaub uas tsis xav tau (Eco-Construction Journal 2023). Cov emulsions no kuj pab tswj kev tsim khoom uas ua haujlwm zoo dua rau huab cua, txo cov kev puag siab CO∞ txog 25% zoo li cov kev ua haujlwm uas siv cov solvents.

Tsis Muaj Qhov Hluv Nyob Rau Hauv Water-Based Chemistry

Lub VAE emulsions txiav tshab cov ntsuab cua siv solvent rau cov ntxiv los ntawm kev siv dej. Qhov teeb meem yog? Kev siv cov khoom no tuaj yeem cuam tshuam dej hauv av txog 90% tsawg dua. Dej hauv av nyob zoo dua vim tias peb tsis tsum siv cov solvent feem ntau lawm. Tom qab ntawd, lub cev muaj ceev kuj zoo dua, uas yog qhov tseem ceeb heev rau qhov chaw nyob hauv ntej xwm txheej uas cov neeg ua haujlwm tau nyob hauv lub cev muaj ceev. Kev saib xyuas kuj nyob rau dej, uas yog qhov yooj yim dua heev. Peb ploij tau txog 60 mus rau 70% tsawg dua ntawm cov khoom nyuaj ruaj thaum siv cov khoom siv solvent. Txawj li cas los xwb, ntau tus neej thiaj xa mus siv qhov no.

Thaum muaj kev nyob rau hauv Green Building Standards thiab cov luj lawm tswj kev sib raug

Ntujmov rau hnub no yog tshuaj tso rau hauv qhov chaw nyob uas muaj VOC sib txawv los ntawm cov leej twg mashiab LEED v4.1 thiab BREEAM, uas txwv rau qhov chaw nyob hauv ntooj liab kom tsis txog 50 grams per liter. Cov chaw tsim khoom uas siv VAE formulas feem ntau pom zoo nrog EPA safety lists ntau dua ib txhis tag, vim tias lawv khoom tau muaj peev xwm los ntawm cov rooj pov thawj tsaisthm thiab tseem ceeb. Thaum lub teb chaws thib ob plhaug los tshuam kev lag luam sib piv, muaj qhov nyiam ntau dua rau cov khoom uas passed Cradle-to-Cradle tests. Cov neeg tsim thiab neeg kho tshuam xav tau cov khoom uas yooj yim siv, tab sis tsis txhob tshuam mus rau hauv qhov tshuab tsha, yog li cov khoom tseem ceeb no tuaj yeem nyob ib puag ncig rau cov neeg xav ntev dua.

Kev sib sau ntaus nqi: Qhov carbon footprint tsawg dua rau cov khoom siv VAE rau kev tsim

Cov kev txheeb xyuas hauv chaw thib ob txhawb tias VAE-modified concrete adhesives yuav txo cov kabon tau 32% kom ntau dua li epoxy. Lub te tsuab kub tom qab (40−50°C vs. 80−120°C rau cov solvent-based) yuav txo kev siv ntxuav nyob rau hauv kev tsim khoom ntim tseg los ntawm 18−22%. Cov kev sim txog thaum kawg ntawm kev siv khoom pom tias muaj 94% tsis toxic nyob rau hauv cov chaw tso khoom kuaj, uas ntau dua OECD cov tshwj xeeb ntawm kev tsis mob.

Global Green Building Certifications (LEED, BREEAM) Influencing Material Selection
