Mu 2026, dimethyl phthalate (DMP), yomwe ndi phthalate ester yogwiritsidwa ntchito mosiyanasiyana komanso yotsika mtengo, yakhala ngati chinthu chofunikira kwambiri pamakampani opanga ma polymer padziko lonse lapansi, zomwe zimapangitsa kuti magwiridwe antchito azikhala bwino komanso kuti ukadaulo ukhale wosiyanasiyana m'magawo ambiri amakampani. Monga pulasitiki yogwira ntchito bwino komanso organic solvent yowiritsa kwambiri komanso yosakanikirana bwino, DMP imagwirizana bwino ndi ma resins osiyanasiyana okhala ndi cellulose, kuphatikiza nitrocellulose, cellulose acetate ndi ethyl cellulose. Kugwirizana kwapadera kumeneku kumapangitsa kuti ikhale chowonjezera chofunikira kwambiri popanga ma topical anti-corrosion, utoto womaliza mipando ndi zinthu zapulasitiki zosinthika za cellulosic, zomwe zimakhala pamalo osasinthika pazinthu zothandizira zapakati komanso zotsika mtengo.
Zophimba zachikhalidwe za nitrocellulose zoyera zakhala zikuvutika ndi zolakwika zamkati mwa zinthu, kuphatikizapo kusinthasintha kosalimba kwa filimu, kusweka mosavuta pansi pa kutentha kochepa, kusagwira bwino ntchito pamwamba komanso kukana nyengo pambuyo poti zakhudzidwa ndi chilengedwe chakunja kwa nthawi yayitali. Mayeso ambiri oyerekeza mafakitale atsimikizira kuti kuwonjezera koyenera kwa DMP yoyera kwambiri kumatha kusintha bwino ndikukonza kapangidwe ka mamolekyulu olumikizirana a mafilimu ophimba panthawi yochira. Zimawonjezera kwambiri kusinthasintha konse, kunyezimira kosalala pamwamba, kukana kukanda komanso kukana nyengo kwanthawi yayitali kwa zophimba zomalizidwa. Pakadali pano, kapangidwe kokhazikika ka mankhwala ndi kukhuthala pang'ono kwa DMP kumalimbitsa kwambiri mphamvu yolumikizira ya zomatira zochokera ku cellulose, ndikuthetsa bwino ululu wamba wamafakitale monga kulephera kwa guluu, kusweka ndi kulimba kosakwanira komwe kulipo kwambiri muzokongoletsa zomangamanga ndi zida zolumikizira mkati mwa magalimoto.
Mu ntchito yaukadaulo yokonza pulasitiki ya cellulosic, DMP imagwira ntchito ngati chofewetsa komanso chopaka pulasitiki chabwino kwambiri chomwe chimayang'anira chilengedwe cha mapepala apulasitiki a cellulosic, mafilimu owoneka bwino komanso zinthu zosiyanasiyana zopangidwa ndi jekeseni. Mosiyana ndi mapulasitiki wamba otsika mtengo omwe amachititsa kuti zinthu zikalamba mosavuta komanso kusasinthasintha kwakukulu, DMP imatha kulinganiza bwino kusinthasintha ndi kukhazikika kwa kapangidwe ka zinthu za polima, kupewa mavuto wamba monga kutentha kochepa, kutentha kwambiri komanso kusokonekera kwa zinthu. Akatswiri ofufuza zamsika akuneneratu kuti ndi kuchira kosalekeza komanso chitukuko chakukula kwa zomangamanga, magalimoto atsopano amphamvu komanso makampani opaka chakudya mu 2026, kufunikira kwa msika wapadziko lonse wa DMP wamafakitale oyeretsa kwambiri m'minda yamafuta ndi zinthu za cellulosic kudzasunga njira yokhazikika yokulira chaka ndi chaka, ndi kuthekera kwakukulu kwakukula kwa msika mu theka lachiwiri la chaka.
