Ngowama-2026, i-dimethyl phthalate (DMP), i-ester compound ye-phthalate eguquguqukayo nexabiso liphantsi, ivele njengesixhobo esincedisayo esiphambili kwishishini lehlabathi lokuvelisa i-coating kunye ne-cellulosic polymer, iqhuba ngempumelelo ukuphuculwa kokusebenza okuzinzileyo kunye nokuphindaphinda kwetekhnoloji kumacandelo amaninzi emizi-mveliso asezantsi. Njenge-plasticizer esebenza kakuhle kunye ne-organic solvent ebila kakhulu ene-miscible egqwesileyo, i-DMP ibonisa ukuhambelana okuphezulu kunye noluhlu olubanzi lwee-resins ezisekwe kwi-cellulose, kubandakanya i-nitrocellulose, i-cellulose acetate kunye ne-ethyl cellulose. Olu kuhambelana lukhethekileyo lwenza ukuba ibe sisongezelelo esisebenzayo esibalulekileyo kwimveliso ye-anti-corrosion coating yemizi-mveliso ekumgangatho ophezulu, iipeyinti zokugqiba ifenitshala kunye neemveliso zeplastiki ze-cellulosic eziguquguqukayo, ezithatha indawo engenakutshintshwa kwizixhobo ezincedisayo zekhemikhali eziphakathi nezisezantsi.
Iingubo ze-nitrocellulose ezicocekileyo zemveli bezisoloko zihlushwa ziziphene zezinto ezibonakalayo, kubandakanya ukuguquguquka okungalunganga kwefilimu, ukuqhekeka lula phantsi kweemeko zobushushu obuphantsi, ukunamathela okungonelanga komphezulu kunye nokumelana okubuthathaka kwemozulu emva kokuvezwa ixesha elide kwindawo engaphandle. Inani elikhulu lovavanyo lokuthelekisa kushishino luqinisekisile ukuba ukongezwa okufanelekileyo kwe-DMP ecocekileyo kakhulu kunokulungisa ngokufanelekileyo kwaye kulungise isakhiwo se-molecular cross-linking seefilimu zokugquma ngexesha lokunyanga. Kuphucula kakhulu ukuguquguquka ngokubanzi, ukukhanya okugudileyo komphezulu, ukumelana nokukrwela kunye nokumelana kwemozulu ixesha elide kweengubo ezigqityiweyo. Okwangoku, isakhiwo seekhemikhali esizinzileyo kunye ne-viscosity ephakathi ye-DMP ziqinisa kakhulu amandla okugquma kwee-adhesives ezisekelwe kwi-cellulose, zisombulula ngokugqibeleleyo iindawo eziqhelekileyo zentlungu yemizi-mveliso ezifana nokusilela kwe-adhesive layer brittle, ukuxobuka kunye nokuqina okungekho sikweni okukhoyo kakhulu kwiimhombiso zokwakha kunye nezixhobo zokugquma zangaphakathi zeemoto.
Kwicandelo lobungcali lokucubungula iplastiki ye-cellulosic, i-DMP isebenza njengesixhobo esithambileyo nesinobuhlobo nokusingqongileyo kunye ne-plasticizer kwiishiti zeplastiki ze-cellulosic, iifilimu ezicacileyo kunye neemveliso ezahlukeneyo ezibunjiweyo ezifakwe injection. Ngokungafaniyo neeplastiki eziqhelekileyo ezikumgangatho ophantsi ezibangela ukuguga kwezinto kunye nokuguquguquka okuphezulu, i-DMP inokulinganisela ukuguquguquka kunye nokuzinza kwesakhiwo sezinto ze-polymer, iphephe ngempumelelo iingxaki eziqhelekileyo zomgangatho ezifana ne-crystallization yobushushu obuphantsi, ukuguquguquka kobushushu obuphezulu kunye nokuqhekeka kwemveliso. Abahlalutyi beemarike abaziingcali baqikelela ukuba ngokuvuselelwa okuqhubekayo kunye nophuhliso olukhulayo lwezakhiwo ezisezantsi, amashishini amatsha eemoto kunye nokupakisha ukutya ngo-2026, imfuno yemarike yehlabathi ye-DMP ecocekileyo kakhulu kwimizi-mveliso kwiindaza zokufaka i-industrial kunye nezinto ze-cellulosic iya kugcina indlela yokukhula ezinzileyo unyaka nonyaka, kunye namathuba amakhulu ophuhliso lwemarike kwisiqingatha sesibini sonyaka.
