Inxalenye yomatshini we-PI

I-Polymimide yesakhiwo semolekyuli iqulethe iiposti ze-heteraclic Polymer yeColymer esekwe kwi-chain ye-chain, igama lesiNgesi li-Pi, i-POLYAMID-I-POLYIID-INDAWO YOKUGQIBELA ) Iindidi ezine.

I-PI okwangoku yeyona nto ibalaseleyo yobunjineli bobuchwephesha, ezinye iintlobo zingamelana nobushushu obude kangangexesha elide kangangexesha elifutshane lokuza kuthi ga kwiqondo lokushisa elifutshane le-490, kodwa ikwakhona -269 ℃ I-Helium engamanzi ayiyi kuba yintsimbi. Ukongeza, iipropathi zoomatshini, ukuchasana nokungakhathali, ukuzinza komhlaba, iipropathi zombane zilungile, hayi i-oyile, hayi i-alkali, i-alkali, ineepropathi ezigqwesileyo, i-ampasion propas. Kwaye i-PI ayinatyhefu, inokusetyenziselwa ukwenza i-tablical yetafile kunye nezixhobo zonyango, kunye nokumelana namawaka amawaka amawaka.

Iindlela zokubumba ze-PI ziqokelela ukubumba, nenaliti, inaliti, ihlafuno, ukhula, ukubopha, ukulahla, ukuhambisa, kunye nokudlulisela ukubumba.

Imbali yoPhuculo

I-Polymimide (PI), yaqala yavela ngo-1955 i-oterent yelungelo elilodwa loRolly, ngo-1961 ivelise i-Polyt (Teramethybone Toracar Acid) ifilimu phantsi kwegama leKapton. Ngo-1972 IMIQATHANGO YOKUGQIBELA EQHALASELA NOPHUHLISO Emva koko, amashishini e-UJE Japan, inkampani yeekhemikhali zaseMitsui kunye namanye amazwe aseYurophu baye bakuqonda imveliso yezorhwebo ye-pollilomide. Ukuza kuthi ga ngoku, iPolymimide inezinto ezingaphezu kwama-20, i-United States, iYurophu neJapan, ngaphezulu kwabavelisi abangama-40. I-South Korea, eMalaysia, iRussia neTshayina inenani elincinci labavelisi kwimveliso kunye nokusetyenziswa kwePolymimide. Ngo-2005, amandla emveliso yehlabathi jikelele amathoni angama-60,000, apho, i-China ibalwa malunga ne-5,000 yeetoni.

Isicelo

I-PI inezicelo zokusetyenziswa kwenqwelo moya, iimoto, oomatshini boMbane, oomatshini bokusebenza, njl njl. Njengeenjini zenjini yemoto, ibheri, i-piston iprints, iibhodi zesekethe eziprintiweyo, iibhloksi zefayili, iibhloko ezichaphazela ubushushu, amaqondo obushushu ahleliyo, kunye nexesha lokuziqhelanisa neqondo lokuzimela, kunye nexesha lokuzibulala Iigiya kuMzi-mveliso woomatshini, kwaye unokusetyenziswa kwishishini le-automotive. Amaqondo obushushu aphezulu azonakalisa, i-compressor blade kunye nomatshini wepiston, i-rings, izixhobo zesixhobo se-subres, i-shorhers, njl .. ..

I-Polyetherimide ineepropathi ezigqwesileyo, iipropathi zombane, ukunganyangeki kweqondo lokungakhathali kunye nophantsi kunye nokuzicingela okuncinci kunye nokuzicingela okuncinci, ukunyibilika kwe-0.5% ye-0.7%. I-Pei inokuba nenaliti kunye nokuphuma kwe-trusision, ukuqhubekeka kweposi kulula, kunokuba lula okanye iintlobo ngeendlela ze-welding kunye nezinye izixhobo, izixhobo ze-aerospace, izixhobo zonyango kunye namanye amashishini asetyenziswa ngokubanzi. I-GE nguMvelisi omkhulu weHlabathi we-Pei, kwaye ezinye iiplanga zobunjineli bezingapheliyo zePlasticics zePlastiki zokubonelela nge-PII ALTYS kunye nezinye iimveliso eziguqulweyo. Imeko yoPhuhliso kukuziswa kwesakhiwo se-P-phenyledine okanye kunye nolunye uhlobo lweplatericl olukhethekileyo lokuphucula ukumelana nobushushu; okanye nge-PC, i-PP, i-PA kunye nezinye iiplasitiki zobunjineli bokuphucula amandla ayo.

Ukomelela kwe-Polyamide okwangoku kungoyena ndoqo uphazamisayo, lo mbala wamandla ombala we-190mpa, ukugoba kwe-250mpa. I-1.8MPA ilayisha ubushushu obushushu be-subtortion ye-274 ℃. I-Pai inomchasi ofanelekileyo kunye nobushushu obuphezulu, ubushushu obuphakamileyo phantsi kwepropathi ye-elektromagnetic yentsimbi kunye nezinye izinto zinezinto ezintle. Isetyenziselwa ikakhulu iigiya, iingqengqelo, iirhasi, iibheringi kunye nokwahlula izingqengqelo zabaqeleli, njl njl.
