Pyromellitic DianhydrideCAS2420-87-3: "Ifarashi yijimye" mu rwego rw'ibikoresho bishya bya shimi ikurura inganda

Mu minsi ishize, mu gihe cy’iterambere ry’inganda zikora imiti, pyromellitic dianhydride (PMDA), imvange y’ingenzi, yinjiye mu buryo bucece mu kwibanda, yongera imbaraga mu guhanga udushya tw’ibikoresho byinshi bigezweho, inatera urujya n’uruza rw’ubushakashatsi mu nganda, mu mashuri makuru no mu nzego z’ubushakashatsi.

Nk’ikintu cy’ingenzi mu binyabutabire by’umwimerere, pyromellitic dianhydride ishobora gusa n’aho idatangaje iyo uyirebye bwa mbere, ariko mu by’ukuri ifite ubushobozi budasanzwe. Ku ruhande rw’umusaruro, ibigo byinshi by’ibinyabutabire byo mu gihugu birimo kongera imbaraga mu kuvugurura no kwagura umurongo w’umusaruro wabyo. [Izina ry’Isosiyete] Chemical Co., Ltd. imaze kurangiza kunoza no kuvugurura inzira yo gukora pyromellitic dianhydride. Ikoranabuhanga rishya rikoresha uburyo bw’ubwenge bwo kugenzura bugena neza ibipimo by’ingenzi nk’ubushyuhe n’umuvuduko w’ibisubizo. Ibi byongereye hafi 3% by’ubuziranenge bw’umusaruro kandi bigabanya cyane umwanda. Ntabwo byemeza gusa ko ireme ry’ibicuruzwa bikurikira rihamye ahubwo binatuma umusaruro urushaho kuba mwiza, umusaruro uva kuri buri gice wiyongeraho hejuru ya 20%, biha isosiyete inyungu ya mbere ku isoko rihanganye cyane.

Mu rwego rwo gukoresha, dianhydride ya pyromellitic irushaho kuba nziza. Amatsinda y'ubushakashatsi ahora ashakisha ubushobozi bwayo mu guteza imbere ibikoresho bikora neza. Ku bijyanye n'ibikoresho by'ikoranabuhanga, firime ya polyimide ikozwemo ifite ubunini bungana na kimwe cya kabiri cy'ibikoresho bisanzwe bikingira ubushyuhe, nyamara ishobora kwihanganira voltage igera kuri volts amagana, ifite amashanyarazi ahoraho, kandi ifite ubushobozi bwiza bwo gukwirakwiza ubushyuhe, itanga igisubizo cyiza ku kibazo cyo gukingira no gupakira utumashini duto, twiza mu bikoresho by'itumanaho bya 5G ndetse no mu bikoresho by'itumanaho bya 6G bizaza. Ikigo gikomeye mu ikoranabuhanga rya elegitoroniki cyageze ku bufatanye n'abatanga ibikoresho fatizo byo hejuru kandi cyafashe iya mbere mu kugerageza ibikoresho bifunga utumashini bifite firime nshya ya polyimide, giharanira kuba ku isonga mu irushanwa ry'ibikoresho by'ikoranabuhanga ry'itumanaho byo mu gihe kizaza.

Urwego rw'indege narwo ntirusigaye inyuma. Kubera imiterere y'ibikoresho biva muri dianhydride ya pyromellitic irangwa n'ubushyuhe bwinshi n'imirasire, pulasitiki zikoreshwa mu gukora ibikoresho byoroshye birinda ku nkengero z'amababa y'indege. Ugereranyije n'ibice bisanzwe by'icyuma, bigabanya uburemere ku kigero cya 30%, bigabanyiriza neza ikoreshwa rya lisansi kandi bigafasha imodoka zo mu kirere kuguruka kure kandi mu buryo buhamye. Byongeye kandi, iyo ibikoresho biva muri iki kintu byinjijwe mu bice by'inyuma by'insinga zihariye z'ibikoresho byo mu kirere, bishobora kwihanganira itandukaniro rikomeye ry'imirasire n'ubushyuhe, bigatuma amakuru ahora akwirakwira mu gihe cy'ubutumwa bukomeye bwo mu kirere.
