Muaj qee cov kev tshaj tawm uas peb paub zoo tab sis ntau tus neeg yuav tsis paub meej. Piv txwv li,
Muaj 0 sucrose nyob rau hauv cov khoom noj, tab sis nws tsis tau txhais hais tias tsis muaj qab zib.
Muaj 0 rog nyob rau hauv cov khoom noj, tab sis nws tsis sib npaug rau cov calories.
Qee cov kev cai yuav hais tau tias nyuaj rau kev tiv thaiv xws li thaj chaw ntawm cov silicone "ntsuab" sealant. (Cov sealant "ntsuab" txhais tau hais tias cov sealant uas zoo rau ib puag ncig )
Cov tshuaj nplaum silicone tau siv rau hauv kev tsim kho tau ntau xyoo, thiab feem ntau siv rau kev sib khi thiab kev sib txuas hauv kev tsim cov phab ntsa ntaub thaiv, qhov rooj thiab qhov rai, kev sib dhos thiab lwm yam teb. Nrog rau kev nce qib ntawm nroog, cov tshuaj nplaum silicone tau nkag mus rau hauv txhua qhov chaw ntawm lub neej. , Teeb pom kev zoo, khoom siv hauv tsev thiab lwm yam me me ua lub luag haujlwm uas tsis tuaj yeem kwv yees tau. Tam sim no, cov tshuaj nplaum silicone tau siv ntau dua thiab ntau dua, thiab cov neeg siv khoom xav tau cov tshuaj nplaum silicone tsis txwv rau kev sib txuas yooj yim thiab kev sib khi. Tib lub sijhawm, kev ua haujlwm carbon ob npaug kuj tau muab cov kev cai tshiab rau tag nrho cov pa phem ntawm cov tsev. Nyob rau hauv kev sib tshooj ntawm ob qho tib si, cov tshuaj nplaum silicone ntsuab thiab ib puag ncig zoo tau dhau los ua qhov sib txawv tshiab hauv kev lag luam.
Cov kev xav tau tshiab tau tshoov siab rau cov lag luam tshiab. Cov neeg siv khoom ib txwm yuav tsum xaiv cov khoom siv silicone "ntsuab" tiag tiag li cas?
Niaj hnub no, peb nrhiav cov lus teb ua ke nrog koj!
1. Cov xwm txheej twg thiaj li suav tias yog cov khoom siv silicone "ntsuab" tiag tiag?
Ua ntej piav qhia txog cov khoom siv foob "ntsuab", peb yuav tsum xub nkag siab tias cov khoom "ntsuab" yog dab tsi? Feem ntau yam peb hu ua cov khoom "ntsuab" yuav tsum tau txiav txim siab los ntawm plaub yam ntxwv ntawm lub zog, cov peev txheej, ib puag ncig thiab qhov zoo ("Cov Cai Dav Dav rau Kev Ntsuam Xyuas Cov Khoom Ntsuab" GB / T33761-2017).
Hauv kev lag luam ntawm cov sealant, ob yam ntxwv ntawm lub zog thiab cov peev txheej tsis muaj feem cuam tshuam rau kev ua haujlwm ntsuab ntawm cov sealant silicone. Ib puag ncig thiab qhov zoo tau dhau los ua ob yam ntxwv tseem ceeb tshaj plaws rau kev ntsuam xyuas seb cov sealant silicone puas yog "ntsuab". VOC qis, tsis muaj tshuaj lom rau lub cev, zoo (tsis yog roj-nthuav dav) thiab lwm yam poob rau hauv qeb ntawm ob qho tib si.
2. Yuav ua li cas thiaj txhais tau tias VOC qis? Tus qauv tshiab tshaj plaws txog qhov txwv ntawm cov ntsiab lus VOC yog dab tsi?
Ntawm ob qho ntawm ib puag ncig thiab qhov zoo, VOC qis tuaj yeem hais tias yog ib qho ntawm cov yam ntxwv ib puag ncig uas cov neeg siv khoom paub zoo tshaj plaws. Txij li xyoo 2001, cov qauv kev cai hauv tebchaws no tau ua kom meej meej cov kev cai rau kev txwv cov tshuaj lom neeg hauv cov sealants rau kev kho kom zoo nkauj sab hauv -
GB 18583 "Cov Khoom Siv Kho Kom Zoo Nkauj Sab Hauv - Cov Kev Txwv ntawm Cov Khoom Phom Sij hauv Cov Nplaum"
GB 30982 "Kev Txwv ntawm Cov Khoom Phom Sij hauv Cov Nplaum Siv Hauv Kev Tsim Kho"
GB/T 33372 "Kev Txwv ntawm Cov Khoom Siv Organic Uas Hloov Tau Hauv Cov Nplaum"
……
Thaum Lub Peb Hlis 4, 2020, Pawg Neeg Saib Xyuas Kev Cai Lij Choj Hauv Tebchaws tau tshaj tawm tus qauv tshiab GB 33372-2020 "Kev Txwv ntawm Cov Khoom Siv Organic Uas Hloov Tau Hauv Cov Nplaum", uas tau faib cov kev cai txwv rau cov nplaum hauv ntau qhov chaw thov. Rau tib hom nplaum, cov nqi txwv VOC sib txawv kuj raug cais raws li qhov xwm txheej tiag tiag ntawm ntau qhov chaw thov.
▼VOC cov ntsiab lus txwv ntawm cov nplaum loj (GB 33372-2020)
3. Ntxiv rau qhov VOC qis, yuav ua li cas txhais cov yam ntxwv thiab kev ua tau zoo ntawm cov khoom siv silicone "ntsuab"?
01. Kev Lom Zem Tsawg
Tam sim no, cov khoom siv foob silicone uas tsis muaj zog feem ntau muaj nyob hauv khw feem ntau muab faib ua cov khoom siv foob cawv thiab cov khoom siv foob ketoxime raws li cov khoom me me uas tso tawm thaum lub sijhawm kho. Cov khoom siv foob cawv, cov khoom me me uas tso tawm thaum lub sijhawm kho feem ntau yog cov khoom me me ntawm cawv xws li methanol, ethanol (feem ntau hu ua cawv), thiab cov khoom siv foob ketoxime, cov khoom me me uas tso tawm thaum lub sijhawm kho feem ntau yog ketone oximes xws li butanone oxime.
Kev Ntsuas Tshuaj Lom ntawm Cov Khoom Uas Hloov Tau (Cov Qauv Cog Qoob Loo)
Ob hom tshuaj sealant thiab cov nroj tsuag tib yam tau muab tso rau hauv qhov chaw kaw rau 10 hnub, thiab kev cuam tshuam ntawm ntau hom tshuaj sealant rau kev loj hlob ntawm cov nroj tsuag tib yam tau tshawb nrhiav. Qhov sib txawv ntawm kev tiv thaiv ib puag ncig ntawm cov tshuaj sealant hom cawv thiab ketoxime tau piv los ntawm biotoxicity.
Cov txiaj ntsig ntawm kev sim yog raws li nram no:
Cov kev xaus lus sim qhia tau hais tias cov molecule me me ntawm cov cawv uas tso tawm thaum lub sijhawm kho cov sealant uas muaj cawv tsis muaj cov teebmeem tsis zoo rau kev loj hlob ntawm cov nroj tsuag, thiab zoo rau ib puag ncig.
02. Cov khoom siv foob zoo
Txhawj xeeb txog kev tiv thaiv ib puag ncig thiab kev noj qab haus huv ntawm ib puag ncig sab hauv tsev ntawm cov tsev,SiwayNws pom zoo kom cov neeg siv xaiv cov khoom siv sealant zoo thiab zoo, thiab tsis txhob yuav thiab siv qee yam khoom qis thiab tsis zoo hauv khw, xws li cov sealant uas muaj roj puv nrog cov sealant roj dawb. Nws tsis yog tsuas yog tsis ruaj khov xwb, nws yuav laus, tawg, thiab tawg, tab sis cov roj dawb uas muaj nyob hauv nws yuav txuas ntxiv mus thiab vaporize, ua rau muaj ntau TVOC emissions, uas cuam tshuam rau ib puag ncig sab hauv tsev, thiab kev ua haujlwm tiv thaiv ib puag ncig tsis tuaj yeem lav.
4. Yuav ua li cas xaiv hom tshuaj sealant "ntsuab"?
Hauv ib lo lus:
Tsuas yog xaiv SIWAY!
Ua ib lub hom lag luam ua lag luam hauv kev lag luam sealant, SIWAY yeej ib txwm cog lus rau kev nyab xeeb, ntsuab, thiab noj qab nyob zoo. Ntawm ib sab tes, nws tau xyaum ua lub tswv yim ntawm kev txhim kho ntsuab hauv tag nrho cov txheej txheem ntawm kev tshawb fawb khoom thiab kev txhim kho, kev tsim qauv mis, cov qauv tswj xyuas zoo, thiab kev tsim khoom ntse.
Nyob rau sab tes tod, nws kuj teb rau qhov kev hu rau "daim ntawv pov thawj ntsuab", siv kev tiv thaiv ib puag ncig ntsuab ua lub tswv yim tseem ceeb ntawm lub tuam txhab, thiab ua rau kev lag luam hauv cov nqe lus ntawm cov qauv khoom ntsuab. SIWAY tau koom nrog ua ke hauv kev sau cov qauv xws li tus qauv hauv tebchaws GB / T 35609 "Cov Khoom Ntsuab Tsis Muaj Dej thiab Sealing Cov Khoom Siv" thiab tus qauv pab pawg T / CECS 10029 "Kev Ntsuam Xyuas Cov Khoom Siv Tsev Ntsuab thiab Cov Khoom Siv Sealants", muab cov khoom siv nplaum zoo rau ib puag ncig rau txhua tus neeg siv khoom uas nrhiav kev zoo thiab kev zoo nkauj.
Tom qab koj pom qhov no, koj puas nkag siab tob txog cov tshuaj silicone sealant ntsuab? Tseem xav paub ntxiv txog qhov tseeb ntawm cov khoom, thov tos ntsoov yuav ntsib koj yav tom ntej.
SIWAY tiv thaiv txhua tus neeg siv khoom nrog "Ntsuab",
Ua siab ntev, hla dhau, thiab txhawb zog rau qhov zoo.
