Uma kukhulunywa ngokuklama kanye nobunjiniyela bezakhiwo eziqinile nezingxenye, ukukhethwa kwezinto ezibonakalayo kubaluleke kakhulu.Ama-polymer anamandla aphezulu anikezela ngenye indlela ephoqelelayo ezintweni zendabuko ezifana nezinsimbi, ezihlinzeka ngokuqina okukhethekile, ukuguquguquka, kanye nezinzuzo zokonga isisindo.Lesi sihloko sihlola umhlaba wama-polymers anamandla aphezulu, izakhiwo zawo, nokuthi angakhuphula kanjani ukusebenza kwamaphrojekthi akho.
Ukuqonda Amandla kumaPolymers
Amandla asho ikhono le-polymer lokumelana nokuguquka noma ukuphuka ngaphansi kwengcindezi esetshenzisiwe.Kunezici ezimbalwa ezithonya amandla e-polymer:
- Isisindo se-Molecular:Ama-polymers anesisindo samangqamuzana aphezulu ngokuvamile abonisa amandla amakhulu ngenxa yokwanda kokuthandelwa kweketango namandla aphakathi kwama-intermolecular.
- I-Crystallinity:Izinga le-crystallinity, noma ukuhlelwa kwamaketanga e-polymer esakhiweni esi-odwe, kungaba nomthelela omkhulu emandleni.Ama-polymers acwebezelayo aphezulu avame ukuba namandla.
- I-Crosslinking:Ukwethula ama-crosslink phakathi kwamaketanga e-polymer kudala inethiwekhi eqinile, ethuthukisa amandla nokuzinza kwe-dimensional.
Izinhlobo zamaPolymers Amandla aphezulu
Uhlu olubanzi lwama-polymers anamandla aphezulu luhlinzeka ngezidingo ezahlukahlukene zobunjiniyela.Nazi ezinye zezinhlobo ezivelele kakhulu:
- I-aromatics (i-Aramids, i-Polyimides):Lawa ma-polymers anezilinganiso ezihlukile zamandla nesisindo, ukuncipha komlilo, nokumelana okuhle kwamakhemikhali.Bathola izinhlelo zokusebenza emikhakheni enzima efana nezinhlanganisela ze-aerospace, ukuvikelwa kwe-ballistic, nezindwangu ezisebenza kahle kakhulu.
- I-Polyethylene (HPPE) esebenza kakhulu:Yaziwa ngamandla ayo avelele omthelela kanye nokumelana nokuhuzuka, i-HPPE ivamise ukusetshenziswa ezintanjeni, emiculweni yokuvikela i-ballistic, namagilavu amelana nokusikwa.
- I-Polycarbonate (PC):Le polymer eguquguqukayo inikeza ibhalansi enhle yamandla, ukucaca, nokumelana nomthelela.Isetshenziswa kakhulu ezintweni zokuphepha, amafasitela angavimbeli izinhlamvu, nasezintweni zesakhiwo.
- I-Acrylonitrile Butadiene Styrene (ABS):Iyaziwa ngamandla ayo amahle, ukuqina, kanye nokucutshungulwa kalula, i-ABS iyinketho edumile yezinhlelo zokusebenza ezahlukahlukene njengezingxenye zezimoto, amapayipi, nezivalo zikagesi.
- I-Ultra-high Molecular Weight Polyethylene (UHMWPE):Iqhayisa ukumelana nokugqokwa okukhethekile kanye nokungqubuzana okuphansi, i-UHMWPE ithola izinhlelo zokusebenza kumajoyinti okwenziwa, amabheringi, namaphedi okugqoka.
Izinzuzo Zokusebenzisa AmaPolymer Amandla Aphakeme
Ama-polymers anamandla aphezulu anikeza izinzuzo eziningi ngaphezu kwezinto zendabuko, azenze zilungele ukusetshenziswa okuhlukahlukene:
- Okungasindi:Uma kuqhathaniswa nezinsimbi, ama-polymers anamandla aphezulu anikeza ukonga isisindo okubalulekile, okubalulekile ezinhlelweni ezifana ne-aerospace nezokuthutha.
- Ukuqina:Lawa ma-polymers akhombisa ukumelana okukhethekile nokuguga, ukudabuka, umthelela, namakhemikhali, okuqinisekisa ukusebenza okuhlala isikhathi eside.
- Ukuhlukahluka:Ama-polymers anamandla aphezulu eza ngezinhlobo ezahlukene, okuhlanganisa imicu, amafilimu, amashidi, namashubhu, ahlinzekela uhla olubanzi lwezidingo zokuklama.
- Ukumelana Nokugqwala:Ngokungafani nezinsimbi, ama-polymers anamandla aphezulu ngokuvamile amelana nokugqwala, anciphisa izidingo zokulondolozwa.
- Ukuvumelana Nedizayini:Ama-polymer amaningi anamandla aphezulu angabunjwa kalula, abunjwe futhi akhiwe, anike amandla imiklamo eyinkimbinkimbi.
Izicelo ze-High Strength Polymers
Amandla akhethekile kanye nokuguquguquka kwalawa ma-polymer kuwenza alungele ukusetshenziswa okuhlukahlukene kuzo zonke izimboni:
- I-Aerospace:Ama-polymers anamandla aphezulu asetshenziswa ezingxenyeni zendiza, amaphaneli e-fuselage, nezakhi zesakhiwo ngenxa yezakhiwo zawo ezingasindi namandla aphezulu.
- Ezezimoto:Izingxenye ezifana nobhampa, ama-fender, kanye nezingxenye zangaphakathi ngokuvamile zisebenzisa ama-polymer anamandla aphezulu ngezinzuzo zawo zokonga isisindo kanye nokuguquguquka kwedizayini.
- Ukwakha:Amapayipi, ulwelwesi olunophahla, nokuqinisa kwesakhiwo kungasebenzisa amandla nokuqina kwamapholima anamandla aphezulu.
- Izimpahla Zezemidlalo:Kusukela kumishini yezemidlalo esebenza kahle kakhulu efana namafreyimu e-skis namabhayisikili kuya egiyeni lokuvikela, ama-polymers anamandla aphezulu athuthukisa ukusebenza nokuphepha.
- Amadivayisi e-Biomedical:Amalunga okwenziwa, izimila, namathuluzi ezokwelapha azuza ezintweni ezihambisana ne-biocompatible namandla aphezulu wamapholymer athile.
Ikusasa LamaPolymer Amandla Aphakeme
Ukuthuthukiswa kwama-polymers anamandla aphezulu kuwumsebenzi oqhubekayo.Ucwaningo lugxile ekudaleni ama-polymer anezilinganiso eziphakeme kakhulu zesisindo nesisindo, ukumelana nezinga lokushisa okuthuthukisiwe, kanye nokuvumelana kwe-biocompatibility okuthuthukisiwe.Ukwengeza, ukuhlanganisa izinqubo ezisimeme ekukhiqizeni ama-polymers anamandla aphezulu kuthola amandla ngomthelela oncishisiwe wemvelo.
Isiphetho
Ama-polymers anamandla aphezulu adlala indima yokuguqula ubunjiniyela besimanje kanye nomklamo.Amandla azo angavamile, ukuguquguquka, kanye nezakhiwo ezingasindi kunikeza izinzuzo ezibalulekile ngaphezu kwezinto ezivamile.Njengoba ubuchwepheshe buthuthuka, ama-polymer anamandla aphezulu azoqhubeka nokuvela, anikeze amandla ukudalwa kwemikhiqizo eqinile, elula, futhi esimeme yezinhlelo zokusebenza ezihlukahlukene.
