Kev Ua Haujlwm Thiab Kev Siv DOTP Ib puag ncig tus phooj ywg Plasticizer
Jun 10, 2021
DOTP yog ib qho zoo heev plasticizer rau polyvinyl chloride (PVC) yas. Piv nrog rau tam sim no nquag siv dioctyl phthalate (DOP), nws muaj qhov zoo ntawm kev ua haujlwm kub, txias tsis kam, nyuaj rau volatilize, tsis kam rau extraction, yooj thiab hluav taws xob rwb thaiv tsev zog, thiab lwm yam, thiab qhia tau hais tias zoo heev durability nyob rau hauv cov khoom. Resistant rau soapy dej thiab tsis tshua muaj kub yooj. Vim nws cov volatility tsawg. Kev siv DOTP tuaj yeem ua tau raws li qhov ntsuas kub ntawm cov xov hlau thiab cov cables, thiab tuaj yeem siv dav hauv 70 degree-resistant cable cov ntaub ntawv (IEC tus qauv ntawm International Electrotechnical Commission). Cov khoom yas tsim los ntawm DOTP tuaj yeem dhau EU ROHS ntawv pov thawj. Nws tau dhau 73 yam khoom, 6P xeem, thiab nws yog ib puag ncig tus phooj ywg plasticizer.
Nyob rau hauv xyoo tas los no, nrog rau kev muaj koob meej thiab kev txhawj xeeb ntawm cov neeg siv khoom noj khoom haus, thiab ntau thiab ntau ntxiv txwv tsis pub siv cov khoom siv ortho-benzene plasticizers, qee cov plasticizers tsis muaj tshuaj lom rau hluav taws xob rwb thaiv tsev, ntim khoom noj, tshuaj thiab tu cev, wallpaper thiab lwm yam khoom thiab kev ua haujlwm siab. , roj-resistant, extraction-resistant, thiab migration-resistant plasticizers tau raug tsim, tsim thiab muab tso rau hauv kev siv. Qhov no tau ua rau muaj kev nthuav dav ntxiv ntawm kev lag luam sib koom ntawm ib puag ncig tus phooj ywg plasticizers, thiab txuas ntxiv shrinking ntawm cov tsoos plasticizer ua lag luam.
Kev lag luam plasticizer tab tom ntsib cov qauv thiab cov khoom hloov kho. Ntawm lawv, kev sib koom ua lag luam ntawm DOTP tau nce ntau. Cov tuam txhab DOTP hauv tsev kuj tseem yuav txhim kho kev tshawb fawb thiab kev loj hlob sai sai ntawm kev txhim kho ntsuab thiab nyab xeeb nyob rau ob peb xyoos tom ntej no. Hauv 2015, lub peev xwm tsim khoom hauv tsev ntawm DOTP tau nce li ntawm 10 feem pua. Nrog rau kev nce hauv daim ntawv thov ntawm ib puag ncig tus phooj ywg plasticizers, kev noj ntawm cov khoom tseem ceeb tam sim no DOP yuav maj mam txo, thaum noj DOTP yuav nce. Nws cia siab tias qhov kev thov yuav nce 5 xyoo no. feem pua txog.
Qhov kev thov rau ortho-benzene plasticizers yog maj mam txo qis, tshwj xeeb tshaj yog nyob rau hauv cov khoom noj khoom haus, khoom siv kho mob thiab cov khoom ua si. Tam sim no, ntau lub tuam txhab tau pib siv cov yas uas tsis yog phthalic xws li DOTP los hloov phthalic plasticizers. Kev txhim kho kev kho mob, ntim khoom, kev tsim kho, khoom siv, tsheb thiab lwm yam kev lag luam yuav txhawb kev lag luam kev xav tau ntawm DOTP. Lub acceleration ntawm industrialization thiab nce nyob rau hauv kev noj cov yas raw cov ntaub ntawv, cov neeg siv khoom thiab ntim cov khoom yuav txuas ntxiv yog lub ntsiab tsav tsheb rau kev loj hlob ntawm DOTP kev ua lag luam.
