I-polymer honeycomb, eyaziwa nangokuthiI-PP ye-honeycomb core material, iyinto engasindi, enemisebenzi eminingi edumile ezimbonini ezahlukahlukene ngenxa yesakhiwo nokusebenza kwayo okuyingqayizivele. Lesi sihloko sihlose ukuhlola ukuthi liyini ikhekheba lezinyosi le-polymer, ukusetshenziswa kwalo kanye nezinzuzo elinikezayo.

Ikhekheba lezinyosi le-polymer liyinhlanganisela ehlanganiswe uchungechunge lwamayunithi angama-hexagonal enziwe nge-polypropylene (PP) noma amanye ama-polymer resins. Amangqamuzana ahlelwe ngendlela yekhekhe lezinyosi, enikeza impahla isilinganiso esihle kakhulu samandla nesisindo nokuqina. Imvelo engasindi yamakhekheba oju e-polymer iwenza alungele ukusetshenziswa lapho ukunciphisa isisindo kubaluleke kakhulu, njengezimboni ze-aerospace, zezimoto, zasolwandle nezokwakha.

Enye yezinto ezibalulekile zeikhekheba lezinyosi ze-polymeramandla ayo aphezulu kanye nokuqina kwayo, okuyivumela ukuthi imelane nemithwalo esindayo kanye nomthelela ngenkathi igcina ubuqotho bayo besakhiwo. Lokhu kwenza kube yisinqumo esihle kakhulu sezinto eziyinhloko zamaphaneli amasemishi, okuhlinzeka ngokuqiniswa nokusekelwa esikhumbeni sangaphandle. Ngaphezu kwalokho, izakhiwo zekhekheba lezinyosi zinikeza ukumuncwa kwamandla okuhle kakhulu kanye nokumelana nomthelela, okuzenza zifanelekele izinhlelo zokusebenza lapho ukuvikelwa emandleni ashukumisayo nokudlidliza kuyadingeka.

Ukuguquguquka kwekhekheba lezinyosi ze-polymer kudlulela ezimpahleni zayo zokushisa ezishisayo kanye ne-acoustic. Amaseli agcwaliswe umoya ngaphakathi kwesakhiwo sekhekheba lezinyosi akha umgoqo osebenzayo ngokumelene nokudlulisa ukushisa, okwenza kube ukukhetha okuphumelelayo kokufakwa ngaphakathi kwezakhiwo, amaloli afakwe esiqandisini nezinye izinhlelo zokusebenza ezizwela ukushisa. Ngaphezu kwalokho, ukwakheka okunezimbotshana kwekhekheba lezinyosi ze-polymer nakho kunomthelela emandleni ayo okumunca umsindo, okuyenza ibe yimpahla efanelekile yokulawula umsindo nokufakwa ezindaweni ezihlukahlukene.

Ngaphezu kwezakhiwo zabo zemishini kanye ne-insulating,izinyosi ze-polymerziyaziwa nangokumelana nokugqwala kwazo kanye nokuqina. I-inertness ye-polypropylene namanye ama-polymer resins asetshenziselwa ukwenza ama-honeycomb cores enza ukuthi amelane kakhulu nomswakama, amakhemikhali kanye nezici zemvelo, okuqinisekisa ukusebenza kwesikhathi eside nokuthembeka ezimweni ezinzima. Lokhu kwenza ikhekheba lezinyosi le-polymer libe inketho ekhangayo ekusetshenzisweni ezindaweni zasolwandle, izitshalo zokucubungula amakhemikhali, nezakhiwo zangaphandle ezichayeke ezintweni ezigqwalayo.

Sekukonke, ama-honeycombs e-polymer anikezela ngezinzuzo eziningi, kufaka phakathi ukwakhiwa okungasindi, amandla aphezulu, ukufakwa kwe-thermal kanye ne-acoustic, nokumelana nokugqwala, okuwenza abe yimpahla eguquguqukayo elungele ukusetshenziswa okuhlukahlukene. Njengoba ubuchwepheshe nezinqubo zokukhiqiza ziqhubeka nokuthuthuka, ukusetshenziswa kwezinyosi ze-polymer kulindeleke ukuthi kwandiswe ngokuqhubekayo, kunikeze izixazululo ezintsha ezimbonini ezifuna izinto ezingasindi, ezihlala isikhathi eside nezisebenza kahle kakhulu. Kungakhathaliseki ukuthiimboni ye-aerospace, yezimoto, yasolwandle noma yokwakha,amakhekheba oju we-polymer ayaqhubeka nokufakazela ukubaluleka kwawo njengezinto ezithembekile, ezisebenza kahle eziwumgogodla.
