Muna 2026, dimethyl phthalate (DMP), compound ye phthalate ester inoshandiswa zvakasiyana-siyana uye inodhura zvishoma, yakabuda sechinhu chakakosha muindasitiri yekugadzira coating uye cellulosic polymer, ichibudirira kusimudzira mashandiro akasimba uye tekinoroji muzvikamu zvakawanda zvemaindasitiri zviri pasi. Sepurasitiki inoshanda zvakanyanya uye organic solvent inofashaira zvakanyanya ine miscible yakanaka, DMP inoratidza kuwirirana kwepamusoro nemarudzi akasiyana-siyana emaresini akavakirwa pa cellulose, anosanganisira nitrocellulose, cellulose acetate uye ethyl cellulose. Kubatana uku kwakasiyana kunoita kuti ive chinhu chinoshanda chakakosha pakugadzira machira ekudzivirira ngura eindasitiri emhando yepamusoro, pendi yekupedzisa fenicha uye zvigadzirwa zvepurasitiki zve cellulosic zvinochinjika, zvichitora nzvimbo isingatsiviwi mune zvemukati nepazasi zvemakemikari anobatsira.
Machira echinyakare enitrocellulose akachena ave achitambudzwa nezvikanganiso zvechisikigo, kusanganisira kusachinjika kwemafirimu, kutsemuka nyore nyore mumamiriro ekunze asina kupisa, kusakwana kwekunamatira pamusoro uye kusasimba kwemamiriro ekunze mushure mekusangana nemamiriro ekunze kwenguva refu. Miedzo yakawanda yekuenzanisa yeindasitiri yakaratidza kuti kuwedzerwa kwakakodzera kweDMP yakachena kunogona kugadzirisa uye kugadzirisa chimiro chemamorekuru chekubatanidza mafirimu panguva yekupisa. Izvi zvinowedzera zvakanyanya kuchinjika kwese, kupenya kwakapfava kwepamusoro, kuramba kukwenya uye kuramba kwenguva refu kwemamiriro ekunze kwemavara apera. Panguva imwecheteyo, chimiro chemakemikari chakasimba uye viscosity ine mwero yeDMP zvinosimbisa zvikuru simba rekubatanidza maglues akavakirwa pacellulose, zvichigadzirisa zvakakwana marwadzo akajairika eindasitiri akadai sekukundikana kweadhesive layer brittle, kukwenya uye kusagadzikana kuripo zvakanyanya mukushongedza kwekuvaka uye zvinhu zvemukati zvemotokari.
Mubasa rehunyanzvi rekugadzirisa mapurasitiki e cellulosic, DMP inoshanda senzira yekunyorovesa nharaunda uye plasticizer yemapurasitiki e cellulosic, mafirimu matete akajeka uye zvigadzirwa zvakasiyana-siyana zvakaumbwa nejekiseni. Kusiyana nemapurasitiki emhando yepasi anokonzera kukwegura kwezvinhu uye kusagadzikana kwakanyanya, DMP inogona kuyera kuchinjika uye kugadzikana kwechimiro chezvinhu zve polymer, ichidzivirira zvinobudirira matambudziko emhando dzakadai sekristaro inodziya, kupisa kwakanyanya uye kupwanyika kwechigadzirwa. Nyanzvi dzemusika dzinofanotaura kuti nekupora kuri kuramba kuchikura uye kukura kuri kukura kwekuvaka, maindasitiri matsva emotokari uye mapurasitiki ezvekudya muna 2026, kudiwa kwemusika wepasi rose kweDMP yemhando yepamusoro muminda yepurasitiki yeindasitiri uye mapurasitiki e cellulosic kuchachengetedza kukura kwakasimba kwegore negore, nekukura kukuru kwemusika muhafu yechipiri yegore.
