Xyoo 2026, dimethyl phthalate (DMP), ib qho tshuaj phthalate ester uas siv tau ntau yam thiab pheej yig, tau tshwm sim los ua ib qho khoom siv tseem ceeb hauv kev lag luam thoob ntiaj teb thiab kev tsim cov polymer cellulosic, ua rau muaj kev txhim kho kev ua tau zoo thiab kev siv thev naus laus zis hauv ntau qhov kev lag luam hauv qab. Ua ib qho plasticizer ua haujlwm tau zoo thiab cov kuab tshuaj organic kub siab nrog kev sib xyaw zoo heev, DMP qhia txog kev sib raug zoo zoo nrog ntau yam cellulose-based resins, suav nrog nitrocellulose, cellulose acetate thiab ethyl cellulose. Qhov kev sib raug zoo tshwj xeeb no ua rau nws yog ib qho khoom siv tseem ceeb rau kev tsim cov tshuaj tiv thaiv xeb zoo, cov xim pleev rooj tog thiab cov khoom yas cellulosic yooj ywm, nyob hauv txoj haujlwm tsis muaj qhov hloov pauv hauv cov khoom siv tshuaj lom neeg nruab nrab thiab qis kawg.
Cov txheej txheem nitrocellulose ntshiab ib txwm muaj tau ntev los lawm los ntawm cov khoom tsis zoo, suav nrog cov zaj duab xis tsis yooj yim, yooj yim tawg hauv qab qhov kub qis, tsis txaus qhov sib txuas ntawm qhov chaw thiab tsis muaj zog tiv thaiv huab cua tom qab raug rau lub sijhawm ntev rau ib puag ncig sab nraud. Muaj ntau qhov kev sim sib piv hauv kev lag luam tau lees paub tias qhov ntxiv ntawm DMP siab-purity tuaj yeem kho thiab ua kom zoo dua cov qauv sib txuas molecular ntawm cov zaj duab xis txheej thaum lub sijhawm kho. Nws ua rau muaj kev ywj pheej tag nrho, du nto gloss, tiv thaiv khawb thiab tiv thaiv huab cua ntev ntawm cov txheej txheem tiav. Lub caij no, cov qauv tshuaj ruaj khov thiab viscosity nruab nrab ntawm DMP ua rau lub zog sib txuas ntawm cov nplaum cellulose-based, daws tau zoo heev cov teeb meem kev lag luam xws li cov nplaum txheej brittle failure, tev tawv thiab tsis ruaj khov uas muaj nyob hauv kev kho kom zoo nkauj thiab cov khoom siv sib txuas sab hauv tsheb.
Hauv kev ua haujlwm ntawm cov yas cellulosic, DMP ua haujlwm ua tus neeg ua kom mos thiab yas zoo rau ib puag ncig rau cov ntawv yas cellulosic, cov yeeb yaj kiab nyias nyias thiab ntau yam khoom txhaj tshuaj pwm. Txawv ntawm cov yas qis qis uas yooj yim ua rau cov khoom laus thiab muaj kev hloov pauv siab, DMP tuaj yeem sib npaug zoo qhov yooj ywm thiab kev ruaj khov ntawm cov khoom siv polymer, zam tau cov teeb meem zoo xws li kev siv lead ua kub qis, kev hloov pauv kub siab thiab cov khoom tawg. Cov kws tshuaj ntsuam xyuas kev lag luam kwv yees tias nrog kev rov zoo tas mus li thiab kev txhim kho ntawm kev tsim kho hauv qab, kev lag luam tsheb tshiab thiab kev lag luam ntim khoom noj hauv xyoo 2026, kev thov lag luam thoob ntiaj teb rau DMP qib siab hauv kev lag luam txheej txheem thiab cov khoom siv cellulosic yuav tswj hwm kev loj hlob txhua xyoo, nrog rau kev loj hlob ntawm kev lag luam loj heev hauv ib nrab xyoo tom ntej.
