IPlastikis ezikhethekileyo zePistics: Izinto zokusebenza eziphezulu zidibanisa ubuchule kunye nokusetyenziswa
I-Polymimide (PI) yiplastiki ekhethekileyo enepropathi eyahlukileyo ebaluleke kakhulu kumashishini ohlukeneyo ngenxa yokunganyangeki kobushushu obuphezulu, ukwenziwa kombane kunye neepropathi zoomatshini. Ukusuka kwi-Aerospace ukuya kwi-elektroniki kwizixhobo zemoto kunye nezixhobo zonyango, ukusetyenziswa kwe-PI ngokubanzi kwaye kwahluka. Kweli nqaku, siza kuthatha i-in-in-in-in-nvezi ijonge kwipropathi yePlastiki ye-PI kwaye isetyenziswa njani kwishishini lanamhlanje.
Enye yezona ndawo zinyanzelekileyo zePisstics ze-PI kukuchasana kwabo kumaqondo obushushu aphezulu. Ukukwazi ukumelana nobushushu ukuya kuthi ga kwi-250 degrees Celsius ixesha elide, kwaye ngaphezulu kwe-risks ngaphezulu kwexesha elifutshane, lenza izicelo ezifuna ukusetyenziswa kobume beqondo lobushushu. Umzekelo, kwicandelo le-aerospace, i-PI isetyenziswa ekwenzeni ii-Injini ze-Injini zeNdibaniselwano, izikhuselo zobushushu kunye neZakhiwo.
Ukongeza kubushushu obuphezulu lobushushu obuphezulu, i-PI inezinto ezintle zombane. Ukwazi kwayo ukugcina iipropathi zombane ezizinzileyo kuluhlu olubanzi lwamaqondo obushushu kunye nezantya ezikhoyo kukhokelele kuluhlu lwe-Eleclin Services.pintral isetyenziswa ekwenzeni iibhodi zesekethe eziguquguqukayo, i-Incybhu, kunye nokuhanjiswa kwemoto , phakathi kwabanye.
Iiplasitiki ezikhethekileyo zePI zikwanazo neepropathi ezigqwesileyo, kubandakanya amandla e-thensile, ubungqola kunye nobunzima. Ezi ndawo zivumela i-PI ukuba iphumelele kwizicelo zolwakhiwo ezinjengee-injini, amatywina kunye neebherithi kwishishini le-Automotoe. Ukongeza, ukuxhaphaza kukaPi kunye nokusebenza okuphantsi kwengqungquthela kwenza ukuba ibe yinto efanelekileyo yokwenza iindawo ezityebileyo kunye nokuhamba.
Kwicandelo lezonyango, ukungaxhathisi bakaPI's kunye nokuchasana kwe-bic's biomatise kwenza ukuba ilungele ukusetyenziswa kwezixhobo zezonyango, ezifana ne-cathents, kunye neempawu ze-surgens.pings zenza ukuba ziluncedo kwizixhobo ezithile zonyango ezikhethekileyo .
Kummandla, iipletiki ezikhethekileyo ze-PI zinokuziqhelanisa nokusingqongileyo. Kuyanyangezeleka kwiikhemikhali ze-organic kunye ne-inorganic, kubandakanya i-acids, ialkalis kunye nezinyibilikisi. Ngenxa yoko, i-PI inoluhlu olubanzi lwezicelo ekwenzeni i-piipmeng, iitanki kunye neenqanawa kwimveliso yemichiza kunye nemizi mveliso yepetrochemical.
Ngaphandle kwezibonelelo ezininzi, iiplasitiki ezikhethekileyo ze-PI zinemida ethile, ezinjengokusebenza nzima kunye neendleko eziphezulu. Nangona kunjalo, le miceli mngeni iya koyiswa njengenkqubela phambili yetekhnoloji, ivumela i-PI ukuba isetyenziswe kuluhlu olusandayo lwezicelo.
Isishwankathelo, iiplasitiki ezikhethekileyo ze-PI zikwizinto eziphezulu zokusebenza, zokusebenza eziphezulu ezigqwesileyo kuzinzo lobushushu obuphezulu, ukufudumala kombane, kunye neepropathi zoomatshini ziye zabenza badume kumashishini amaninzi. Nokuba kwizicelo ze-aerospace kwiindawo ezinamanqanaba okanye kwi-elektroniki kunye nezixhobo zonyango, iPI ibonakalise ixabiso layo elingafezekanga. Ngophando oluthe kratya kwi-PI PROSTICS kunye nezinto ezinobuthwele, sinokulindela i-PI yokudlala indima enkulu kwizicelo zezemizi-mveliso.
Uphawu kunye nokusetyenziswa kwezixhobo ezikhethekileyo ze-PI
