Iingcebiso malunga neplasitiki yobunjineli bobunjineli

August 13, 2024

Uthetha ukuthini ngamaplanga obukhethekileyo obukhethekileyo?

Iplasitiki ekhethekileyo yobunjineli yintsebenzo iyonke iyonke iphantsi kakhulu, ukusetyenziswa kwexesha elide kwi-150 ℃ Iklasi yeemveliso zerabha, i-PPs), i-POLYECYRY ETERE (LCP) kunye nePolysulfone (PsF). IPlastica yePlastibs ekhethekileyo inenkqubo ekhethekileyo nengasebenzi, kwaye isetyenziswa ngokubanzi kwizixhobo ze-elektroniki kunye nezombane, imveliso ekhethekileyo yeshishini kunye neminye amasimi obuchwephesha obuphezulu.

Iiplasitiki zobunjineli bobunjineli bobunjineli kwinkulungwane yama-20 ubudala baqala i-80, xa i-US kunye neRussia i-Hiegemoy yesibini ye-Ussoine yeCustoment yeNtloko yeTellmer. Ekuqaleni, ibizwa ngokuba yi-Polymer enganyangekiyo (ngokwahlukileyo kwiimveliso zerabha). Okwangoku, ihlala ibizwa ngokuba ziiplasitiki zobunjineli bobunjineli (iplasitiki ye-Expressicgesic) okanye intsebenzo ephezulu yePolymer (iPolymer ephezulu). Ukususela ekuqangeni kwePolyacynikaimitriitile (PI) kwiminyaka engama-60 ukuya kuthi ga kwintengiso yokuqala yama-80, iintlobo eziphambili zophando kunye nophuhliso zigqityiwe:

1. I-polyacylonnikaimiterile (PI);

2. Polyamideimide (Pai);

3. I-Polyetherimide (PeI);

4. I-Polycularlate (i-U-Polymer);

5. I-polyphenyne ether (PPS);

6. Polysulfone (PsF)

7. Polyeherulfone (Pes)

8. I-POLOETER ETER KETOTO (PEEK) njalo njalo.

Special Engineering Plastic machining part

Uphuhliso lweeplasitiki zobunjineli obukhethekileyo

1) Inqanaba lepropathi emzimbeni:

a. Inqanaba eliphezulu lokufakelwa (ichazwe ngokubanzi njenge-IL Index Index ngaphezulu kwe-150 ℃);

b. Amandla aphezulu ngendlela ephakamileyo

c. Umsebenzi ophezulu kakhulu (njengokuxhathisa kwimithombo yemithombo yemitha, ubushushu obuphezulu, imarble).

d. Ukuzinza okungaqhelekanga nangaphaya kweempawu zeepolitiki zemveli.

2) Inqanaba lenkqubo:

a. Imveliso kunye nokulungisa amaqondo obushushu aphezulu (ngokubanzi kwi-300 ~ 400 ℃);

b. Uxinzelelo oluphezulu (ngokubanzi lufuna i-120MPA ~ 160Ma);

c. I-abrasmes kufuneka ifudumezwe (ngokuchaseneyo nokupholisa izinto ezingafunekiyo zeplastiki);

d. Inkqubo yembaleki eshushu ikhetha.

Ukusetyenziswa kweeplasitiki zobunjineli obukhethekileyo

Uhlobo oluqhelekileyo lweplasitiki yobunjineli kukuba intlawulo iyonke incinci kwaye eyona nto iphambili ihlukile. Ezi zixhobo zaza zaza zaza zadalwa zokufezekisa iimfuno zeshishini lokhuselo okanye uphando lwenzululwazi. Okwangoku, isicelo sifudukele kwinqanaba laseburhulumenteni.

1. I-Aerospace yobunjineli

Ngenxa yokusetyenziswa okhethekileyo kwendawo ye-shuttle, ngoko kufuna ukuba ubunzima bezinto zinobunzima bokukhanya, ubunzima obuphakamileyo, ukumelana nobushushu, iimpawu eziphezulu zokuhlawula ilangatye. I-PI, i-Peek, i-PPs kunye ne-Polyamidemide kunye nezinye izinto ezinobushushu obuphakathi obuphezulu kunye nokubambelela ekusebenziseni ubushushu, ngoko ke kumzi-mveliso we-Aerospace kakhulu.

2. IPHONDO LENTSHONA KOLWAZI

Iiplasitiki zobunjineli ezikhethekileyo ezisetyenziswa kwicandelo lolwazi ngombane. Ikakhulu iqulethe:

. Ngenxa yokusebenza kakuhle kweeplasitiki zobunjineli (ukuba kwimeko encinci kakhulu isenokungavisisani ngokuchasene nobushushu, njl njl. Gxila kubunjineli obukhethekileyo beenjini zobunjineli.

3. Iinkonzo zonyango

Kule minyaka yangoku. Izixhobo ze-polymer ze-polymer ziqhele ukusetyenziswa ngezinto zonyango ze-microbiological (ezinjengamalungu e-ofisi, amayeza e-urifary, i-endoscopes, njl. Njl.). Ngenxa yokuba izixhobo zePolymer zezonyango zinokuhlengahlengiswa njengezakhiwo zezinto kunye nezinto ezibonakalayo zinepropathi eyahlukeneyo (njengokuxhathisa ukwaluphala kwezinto eziphilayo, njengezixhobo zexesha elide, zikulungele, njalo njalo Ingqwalaselo ngokubanzi yehlabathi kwizinto ezincinci ze-microbiological kwicandelo elibanzi lokusetyenziswa, elona nani liphezulu leentlobo. Kulula ukuyiqhubela phambili, inokujamelana nokucoca rhoqo kunye nokucocwa, kwaye i-Solvent ukunganyangeki. Ngenxa yoko, ngokuthe ngcembe kuyasetyenziswa ekwenzeni kwezixhobo zezonyango, iinkqubo zokubuyela kwiziyobisi, kunye namathambo abantu.

4. Intsimi kunye namandla

Ukusetyenziswa kwemveliso yebhetri ephezulu yenye yezona zinto ziqhelekileyo zokusetyenziswa kweplasitiki yobunjineli obukhethekileyo kwicandelo lamandla. Iseli ye-Hydrogen i-Hodrogen i-WHOL luhlobo lwe-ispition kwi-elektrochemion yamandla ngendlela yoomatshini kumandla ombane wenkqubo yokuphumeza amandla aphezulu.
