I-Pyromellitic DianhydrideCAS2420-87-3: “Ihashe Elimnyama” Kwicandelo Lezinto Ezintsha Zeekhemikhali Litsala Ingqalelo Kwishishini

Kutshanje, phakathi kophuhliso olukhulayo kwishishini leekhemikhali, i-pyromellitic dianhydride (PMDA), into ebalulekileyo, iye yangena ngokuzolileyo kwindawo eveleleyo, ifaka amandla amakhulu ekuveliseni izinto ezininzi ezikumgangatho ophezulu kwaye iqalise uhambo olutsha lophando kulo lonke ishishini, izazinzulu kunye noluntu lophando.

Njengezinto ezibalulekileyo zekhemikhali yendalo, i-pyromellitic dianhydride isenokubonakala ingaqhelekanga ekuqaleni, kodwa eneneni inezakhono ezizodwa. Kwicala lemveliso, amashishini amaninzi eekhemikhali zasekhaya aqinisa imizamo yawo yokuphucula nokwandisa imigca yawo yemveliso. [Igama leNkampani] Chemical Co., Ltd. isandula ukugqiba ukwenza ngcono nokuphucula inkqubo yemveliso ye-pyromellitic dianhydride. Le teknoloji intsha isebenzisa inkqubo yolawulo ekrelekrele elawula ngokuchanekileyo iiparameter eziphambili ezifana nobushushu bokusabela kunye noxinzelelo. Oku konyuse ubunyulu bemveliso phantse ngama-3 ekhulwini amanqaku kwaye kunciphisa kakhulu umxholo wokungcola. Ayiqinisekisi nje kuphela uzinzo lomgangatho weemveliso ezilandelayo kodwa ikwaphucula kakhulu ukusebenza kakuhle kwemveliso, kunye nemveliso ngexesha leyunithi nganye inyuka ngaphezulu kwama-20%, inika inkampani ithuba lokuqala kwimarike ekhuphisana kakhulu.

Kwintsimi yesicelo, i-pyromellitic dianhydride ikhanya ngakumbi. Amaqela ophando ahlala ehlola amandla ayo ekuphuhlisweni kwezinto ezisebenza kakuhle. Ngokuphathelele izinto ze-elektroniki, ifilimu ye-polyimide eyenziwe kuyo inobukhulu obuyisiqingatha kuphela sezinto zokukhusela zemveli, kodwa inokumelana ne-voltage ukuya kuthi ga kumakhulu aliqela ee-volts, ine-dielectric constant ezinzileyo, kunye neempawu ezilungileyo zokusasaza ubushushu, ibonelela ngesisombululo esifanelekileyo kwingxaki yokukhusela nokupakisha iitships ezincinci, ezichanekileyo kwi-5G kwanakwizixhobo zonxibelelwano ze-6G ezizayo. Ishishini eliphambili letekhnoloji ye-elektroniki lifikelele kwintsebenziswano enobuchule nabathengisi bezinto eziluhlaza eziphezulu kwaye likhokele ekuvavanyeni iimveliso zokupakisha iitships ezixhotyiswe ngefilimu entsha ye-polyimide, lizama ukuba phambili kukhuphiswano lweemveliso zobuchwepheshe bonxibelelwano besizukulwana esilandelayo.

Icandelo leenqwelo moya nalo alikho ngasemva. Ngenxa yeempawu zobushushu obuphezulu kunye nokumelana nemitha yezinto ezenziwe kwi-pyromellitic dianhydride, iiplastiki zobunjineli ezifanelekileyo zisetyenziselwa ukuvelisa izinto ezikhuselayo ezilula emaphethelweni amaphiko eenqwelo moya. Xa kuthelekiswa nezinto zesinyithi zemveli, zinciphisa ubunzima ngaphezu kwama-30%, zinciphisa ngokufanelekileyo ukusetyenziswa kwepetroli kwaye zinceda izithuthi zeenqwelo moya ukuba zibhabhe kude nangakumbi nangokuzinzileyo. Ngaphezu koko, xa izinto ezenziwe kule nto zifakwa kwiileya zangaphandle zokukhusela zeentambo ezikhethekileyo zeeprobe zesithuba, zinokumelana nomahluko omkhulu wemitha ye-cosmic kunye nobushushu, ziqinisekisa ukuhanjiswa kwedatha okuzinzileyo ngexesha lemisebenzi enzima yesithuba.
