Daim ntawv thov 1,3-Propanediol hauv kev lag luam

1,3-Propanediol (PDO)yog ib qho diol uas siv tau ntau yam, rov ua dua tshiab uas tau txais txiaj ntsig tseem ceeb hauv kev lag luam, tshwj xeeb yog vim nws cov khoom siv bio-based.1,3-propanediol covQhov tseem ceeb ntawm kev lag luam nyob ntawm qhov kev sib tshuam ntawm cov ntaub ntawv ua tau zoo (tshwj xeeb tshaj yog PTT fibers) thiab cov tshuaj ntsuab, ua rau cov khoom siv ruaj khov thiab cov khoom siv rau cov neeg siv khoom nrog kev txo qis ntawm cov teeb meem ib puag ncig.

 

·Cov Khoom Siv Polymers & Textiles (Daim Ntawv Thov Loj Tshaj Plaws)

Cov khoom siv raw ntawm Polytrimethylene Terephthalate (PTT): PDO yog condensed nrog terephthalic acid los tsim PTT. (PTT siv dav rau cov ntaub pua plag fiber, Apparel & Activewear thiab Engineering Plastics.)

 

·Cov Khoom Sib Xyaws & Cov Roj Resins

Siv tau ua ib lub monomer los hloov kho Unsaturated Polyester Resins (UPRs) txhim kho kev ywj pheej, kev tawv, thiab kev ruaj khov hydrolytic hauv cov ntawv thov xws li cov tsho tiv no marine gel, cov tank, thiab cov khoom siv tsheb.

Yuav ua Thermoplastic Polyurethanes (TPUs): PDO-based polyols tuaj yeem tsim TPUs nrog cov khoom zoo dua rau cov khau hauv qab, cov khoom siv sab hauv tsheb, thiab cov yeeb nkab ywj pheej.

Siv los tsim cov polyurethanes ua tau zoo nrog kev ruaj khov UV zoo dua, tiv taus tshuaj lom neeg, thiab yooj ywm qis rau cov txheej txheej, cov nplaum, cov sealants, thiab cov elastomers (CASE).

 

·Cov Tshuaj Ntxuav Khaub Ncaws Ua Kua thiab Cov Qauv Ntxuav

Ua haujlwm ua cov tshuaj yaj, cov tshuaj hloov pauv viscosity, thiab cov tshuaj tso cov xim tawm. Nws pab tshem cov av qias neeg, tiv thaiv kev rov ua dua ntawm cov ntaub, thiab txhim kho kev ruaj khov ntawm cov tshuaj ntxuav enzymatic.

 

·Cov kua dej tshem dej khov/Tiv thaiv dej khov

Ib qho khoom xyaw tseem ceeb hauv ntau hom IV "anti-icing" kua rau Dav Hlau De-icing Fluids. Nws muab kev nyuaj siab zoo heev thiab tsim ib daim zaj duab xis tiv thaiv, viscous uas tiv thaiv kev tsim dej khov rau ntawm qhov chaw dav hlau rau lub sijhawm ntev "holdover time" ua ntej nce dav hlau. Nws tsis muaj tshuaj lom thiab zoo rau ib puag ncig dua li qee cov glycols ib txwm muaj xws li ethylene glycol.

 

 

·Muaj peev xwm siv tau zoo hauv kev tsim cov cib ua vaj tse

Ua ib tus neeg sawv cev kho kom zoo thiab txo qhov ntsws, thiab ib tus neeg sawv cev tiv thaiv kev khov kho

PDO yog ib yam khoom siv organic uas khaws dej tau zoo heev. Thaum sib xyaw rau hauv cov mortar rau kev tsim cib, nws tuaj yeem kaw cov dej noo ntev thiab tso nws qeeb qeeb thaum lub sijhawm tom qab ntawm kev ua kom cov cement noo. Qhov no txo ​​qhov kev qhuav thiab tawg, txhawb kev ua kom cov cement noo ntau dua thiab sib npaug, ua kom lub zog thiab qhov ceev ntawm cov cib tom qab, thiab txhim kho kev tiv thaiv ntawm cov cib rau cov voj voog khov-thaw.

-Raws li cov organic binder lossis modifier

PDO siv tau ua polyol los koom nrog kev tsim lossis hloov kho cov polymers (xws li polyurethanes, polyester resins), uas siv tau ua cov nplaum rau cov fibers lossis aggregates hauv lub cib, txhim kho kev ncaj ncees tag nrho. Lub txheej tiv thaiv ntawm qhov chaw ntawm lub cib muab cov haujlwm xws li dej repellency, tiv thaiv huab cua thiab tiv thaiv staining.

 

-Ua ib qho stabilizer rau cov cib ua los ntawm cov khoom ua npuas lossis cov khoom sib dua

Nws cov khoom surfactant pab kom lub npuas ruaj khov thaum lub sijhawm ua npuas dej, ua rau cov qhov hauv ntawm lub cib sib npaug zoo dua thiab me dua. Yog li ntawd, cov cib sib dua nrog kev ua haujlwm rwb thaiv tsev zoo dua thiab muaj zog dua.
