Iiplasitiki ezintathu ezinobushushu obushushu

Intshayelelo

Kule mihla, eli xesha, ukuphuculwa kwesayensi kunye netekhnoloji ebizwa ngokuba kukukhawulezile, inkqubela phambili yeSayensi yezixhobo kwiindawo ezininzi iye yazisa utshintsho olutsha. Iplasitiki yobunjineli obuphezulu yenye yezona zixhobo zibaluleke kakhulu, kubushushu obuphezulu, uxinzelelo oluphezulu, ukususwa okuqinileyo kwezi meko zingqongqo, intsebenzo yazo inokuba yinto entle! Njenge-polyphenyne sulfide (PPS), i-Polyteether Ether Ketone (Pek) kunye nePolymimide (PI) yeyona ilungileyo koku.

Ezintathu zeplasitiki yobushushu obunganyangekiyo

I-polyphenylene sulfide (PPS)

Masiqale ngePolyphenyane I-Sulfiide (PPS). Le yi-crystalline, yokusebenza kakuhle kwi-thermoplastic. Inokumelana nobushushu obuhle, kunye nendawo yokunyibilika malunga ne-285 ° C kunye nobushushu obugqwethekileyo ubushushu be-260 ° C. Oku kuthetha ukuba inokusebenza ngokuzinzileyo ixesha elide kwiindawo ezihlala zingaphezulu kwe-200 ° C. Ayoyiki ukusebenza. Oku kuthetha ukuba inokusebenza ngokuzinzileyo ixesha elide kwiindawo ezingaphezulu kwe-200 ° C kwaye azoyiki ubushushu obuphezulu. Kwaye uzinzo lwayo lukhulu, izinto ezininzi zekhemikhali, ezinje nge-acid eyomeleleyo, i-alkali eyomeleleyo kunye ne-organic, kunzima ukuyibeka njani. Ke kuhlobo lwezityalo zekhemikhali zezinto ezikhoyo kuyo yonke indawo, i-PPS inokuba luncedo, i-PPS yombane ilunge ngakumbi, nangona ishushu neshushu, inokuqinisekisa ukusebenza okuqhelekileyo kwezixhobo ze-elektroniki.

Nangona kunjalo, i-PPS nayo ayinandawo intle kangaka, oko kukuthi, ukuqina kwayo kuhlwempuzekile, ukuba ngempembelelo enkulu, kunokuba yi-brittle. Ukwenzela ukuphucula le nqaku, izazinzulu kunye neglasi ye-fiber fiber okanye i-carbon fiber yomeleza impahla yezinto ezibonakalayo kunye, ngale ndlela, kunokuhlangabezana kakuhle neemeko zokusebenza ezinzima.

Kwizicelo ezisebenzayo, i-PPs inokusetyenziswa ngeendlela ezininzi. Kwishishini le-AutoMotive, amalungu athile ejikeleze i-injini, njengokungena kwizithuba, isetyenziswa ii-PPs eziqhelekileyo ukuba zenziwe. Kwintsimi yombane kunye ne-elektroniki, ezinje ngezixhobo zokunxibelelana, amachaphaza amalahle kunye nezinye iinxalenye ezibalulekileyo, ziya kusebenzisa i-PPS.

I-Polyseretothertotone (i-peek)

I-Polyngure Totone Ukunganyangeki kobushushu obuphezulu akunatyala, indawo yokunyibilika malunga ne-343 ° C kunye neqondo lokushumayela ixesha elide elingaphezulu kwe-250 ° C. Le ndawo ivumela i-peek ukuba isetyenziswe kwiindawo ezinobushushu obuphakathi. Olu phawu luvumela i-PEROK ukuze iqhubeke nokusebenza ngokuzinzileyo kubushushu obuphakathi, nokuba kusenziwa intsimi ye-aerospace, nokuba kusempilweni amaqondo obushushu enjini, okanye kwimveliso yemizi-mveliso yokumelana nobunzima beemeko ze-thermal, i-Peek inokusingathwa ngokulula.

Iipropathi zoomatshini be-Peek nazo zibalaseleyo. Ayisiyo nje amandla aphezulu, inokujamelana namandla amakhulu angaphandle kwaye ingabi lula okanye yonakele, kwaye ukuba nefuthe elilungileyo, kwimpembelelo kunokulufumana amandla. Kwangelo xesha, ukuxhathisa i-arasion egqwesileyo kwingxabano yexesha elide kwaye unxibe imeko esingqongileyo isenokugcina imeko elungileyo.

Ukongeza, i-pieckey ye-teek elungileyo yeyokuphazamiseka okukhulu. Le ndawo inciphisa ukuxabana nokunxiba, ngaloo ndlela yandisa ubukho benkonzo yezinto. Umzekelo, ukuveliswa kweemoto, umzekelo, iinxalenye ezenziwe nge-peek zihlala zisebenza kwaye zizinzile ixesha elide, ukunciphisa isantya solondolozo kunye nokutshintshwa kunye nokunciphisa iindleko. Kwicandelo lezixhobo zezonyango, i-Peek ihlala isetyenziswa ekwenzeni amajoyine odityanisiweyo kunye nezinye izinto, kunye neepropathi zalo zokuzithanda zinceda ekuphuculeni ukushukuma kwamalungu, ngelixa bendisa ubomi babo kwinkonzo kunye nokuzisa iziphumo ezingcono zonyango kunye nokuzisa unyango olungcono kwizigulana.

I-Peek ithandwa kakhulu kwicandelo lezonyango. Ngenxa ye-bimomatisi-bicatoties, iipropathi zoomatshini kunye nokuchasana kweekhemikhali, uninzi lwezi zixhobo zonyango, ezinjengamalungu obunzulu kunye nezixhobo ze-spinal fusion, zenziwa nge-peek. Kwintsimi ye-aerospace, i-Peek ikwathandwa kakhulu, inokusetyenziselwa ukwenza iinjini ze-Injini yenqwelomoya, amaphiko amaphiko eenxalenye zezi zinto, zinokwenza inqwelomoya, ukusebenza kakuhle.

I-Polymimide (PI)

Ilizwi lokugqibela kwiPolymimide (PI). Le yiklasi yamafutha aphezulu obuchwephesha obunganyangekiyo obunganyangekiyo ngeplaterics ye-wobunjineli ngezethutyana. Ukuchasana nobushushu obuphezulu obungaphezulu okulula, kwaye kunokusetyenziselwa ixesha elincinci kubushushu obuphezulu abangama-500 ℃, kunye neqondo lobushushu lokusetyenziswa kwexesha elide linokuba ngama-250 - 300 ℃. Amandla ayo kunye nobungqola baphakamile kakhulu, banokujamelana noxinzelelo olukhulu kunye nokuxinana, isakhiwo asiyiphula. Ngapha koko, i-PI inepropathi efanelekileyo yokuthambisa kwaye yinto efanelekileyo yokufaka i-subring kwiindawo zobushushu obuphezulu.

Kumzi-mveliso we-elektroniki, i-PI ihlala isetyenziselwa ukwenza izinto ze-elektroniki kwiindawo zobushushu eziphezulu, ezinjengeebhodi zesekethe kunye neefilimu ezifakwayo. Kumzi-mveliso we-aerospace, i-PI ingasetyenziselwa ukwenza izinto ezinganyangekiyo zeqondo lobushushu okuqinisekisa ukuba inqwelo moya inokubhabha ngokukhuselekileyo naphantsi kweemeko ezigqithisileyo.

Isishwankathelo

Isishwankathelo, i-polyphenylene sulfide (PPS), i-Polyteether Ether Ketone (Pek) kunye nePolymide (PI) ziintlobo ezintathu zeplasitini. Benze uphawu lwazo kwimoto, i-elektroniki, ezonyango, kunye ne-aerospaces, kwaye uqhubeke nokuqhuba itekhnoloji ngaphambili.
