Ukufaka Isicelo Nokuthuthukiswa Kwezinto Zepulasitiki Zezimoto Ezintsha Zamandla

Njengamanje, ngaphansi kwenkulumo eyisihluthulelo yentuthuko yomhlaba wonke yokugcizelela isu “lekhabhoni ephindwe kabili”, ukonga, okuluhlaza kanye nokugaywa kabusha sekuphenduke umkhuba wokuthuthukiswa kwezinto ezintsha zezimoto nobuchwepheshe obusha, futhi izinto ezingasindi, eziluhlaza kanye nokusetshenziswa kabusha sekuphenduke isiqondiso esiyinhloko sokuthuthukiswa kwezimoto ezintsha. izinto zokwakha. Iqhutshwa igagasi lezimoto ezingasindi, izinto zepulasitiki sezisetshenziswa kabanzi emkhakheni wezimoto ngenxa yomphumela wazo wokunciphisa isisindo. Kungakhathaliseki ukuthi izingxenye zokuhlobisa zangaphandle zemoto, izingxenye zokuhlobisa zangaphakathi ezifana nephaneli yensimbi, iphaneli yomnyango, iphaneli yesisetshenziswa esisizayo, isembozo sebhokisi lamagilavu, isihlalo, ipuleti lonogada elingemuva, noma izingxenye zomsebenzi nesakhiwo, ungabona isithunzi sepulasitiki yonke indawo. Ikakhulukazi okwamanje, izimoto ezintsha zamandla seziphenduke isiqondiso esiyinhloko sokuguqulwa nokuthuthukiswa kwemboni yezimoto emhlabeni wonke. I-lightweight yezimoto ezintsha ezinamandla iphuthuma kakhulu kunezimoto zendabuko. Ububanzi bokusebenza bezinto zepulasitiki bunwetshiwe kugobolondo lebhethri yemoto yamandla entsha nezinye izingxenye. Ngaso leso sikhathi, ukunqanda ilangabi, ukuvikelwa kwemvelo okuphezulu, ukumelana nokuklwebheka, ukucwebezela okuphezulu, ukumelana nokugqwala nokunye ukusebenza kwamapulasitiki ezimoto nakho kubeka phambili izinselelo eziphakeme.

Ukusetshenziswa kwezinto eziningana zepulasitiki ezivame ukusetshenziswa ezimotweni

PA

I-Polyamide PA ijwayele ukubizwa ngeNyiloni. Izakhiwo ezinhle kakhulu zemishini, eziqinile, ezicindezelayo kanye nokumelana nokugqoka. I-PA6, i-PA66, i-PA6 ye-flame retardant ethuthukisiwe isetshenziswa enjinini yezimoto nasezinxenyeni ze-peripheral zenjini, ikhava yenjini, ikhava yokunquma injini, ikhava yekhanda yesilinda, isihlungi sikawoyela, isisula, igrile yerediyetha, njll.

PA66

I-PA66 itholwe nge-polycondensation ye-adipic acid ne-hexandiamine ngesilinganiso se-molar esingu-1:1. I-adipic acid ngokuvamile ikhiqizwa i-hydrogenation ye-benzene ehlanzekile kanye ne-oxidation nge-nitric acid. I-PA66 futhi ingagcina amandla aqinile nokuqina ekushiseni okuphezulu; I-PA66 inamandla amakhulu emishini, ukumelana okuhle kokuqhekeka kwengcindezi, futhi iyinayiloni yokumelana nokugqoka engcono kakhulu; I-PA66 i-self-lubricating inhle kakhulu, eyesibili kuphela ku-PTFE kanye ne-polyformaldehyde; I-PA66 inendawo eshisayo eshisayo futhi iyimpahla ezicisha ngokwayo, kodwa ukumuncwa kwayo kwamanzi kukhulu, ngakho-ke ukuzinza kwayo kobukhulu akulungile.

I-PA6+GF30

I-PA6 GF30 ingumphumela wokuguqulwa kwe-PA6. I-PA6 GF30 ithuthukisa izinto ezibonakalayo ngokungeza imicu yengilazi. I-Glass fiber ngokwayo inokumelana nokushisa, ukumelana nelangabi, ukumelana nokugqwala, ukwahlukanisa ukushisa, amandla aphezulu okubamba ukushisa kanye nokufakwa kahle kukagesi. Ngemva kokuqiniswa i-fiber yengilazi, imikhiqizo ye-PA6 GF30 ingahlangabezana nezidingo zokusetshenziswa kwezimboni nezinsuku zonke, futhi inezici zamandla amahle kakhulu, ukumelana nokushisa, ukumelana nomthelela kanye nokuzinza kwe-dimensional.

PMMA+ASA

I-PMMA, ngokuvamile eyaziwa ngokuthi “i-plexiglass”. Inokuhanjiswa kahle kokukhanya, izakhiwo zemishini kanye nokumelana nokuguga okuhle kakhulu kanye nokumelana nesimo sezulu. Kodwa i-brittleness yayo iphakeme, kulula ukuqhekeka, ukumelana nomthelela kubi.

I-ASA, efana nesakhiwo se-ABS, isebenzisa irabha ye-acrylic ngaphandle kwamabhondi amabili esikhundleni serabha ye-butadiene ku-ABS. Inokuguquguquka okuhle kakhulu, ukumelana nesimo sezulu esihle, nokumelana kangcono nokugqwala kwamakhemikhali. Kodwa ubuso bayo ubulukhuni abuphezulu, ukumelana nokuklwebheka, ukumelana nokugqoka akukuhle.

I-ABS

I-ABS iyi-acrylonitrile - butadiene - styrene copolymer, iyipulasitiki yobunjiniyela be-thermoplastic eguquguqukayo, ukumelana nomthelela, ukumelana nokushisa, ukumelana nokushisa okuphansi, ukumelana namakhemikhali kanye nezakhiwo ezinhle kakhulu zikagesi, kodwa futhi inokucutshungulwa kalula nemikhiqizo ukuqina kosayizi omuhle, isicwebezelisi sendawo, ikakhulukazi esetshenziselwa i-automotive air conditioning tuyere, iswishi, izingxenye zamathuluzi ezizungezile, ipuleti lokuvikela eliqandayo, izibambo zomnyango, Abakaki, ikhava yamasondo, isibonisi sezindlu, isibambo sokuphepha se-fender, njll.

PC/ABS ingxubevange

I-PC/ABS (P acrylonitrile – butadiene – styrene copolymer alloy) : izinzuzo ze-PC zinzima futhi ziqinile, ukonakala ukuqhekeka kwengcindezi, i-viscosity; Izinzuzo ze-ABS ziyi-fluidity enhle, kodwa ubulukhuni obuphezulu obuphansi; Ngale ndlela, into ehlanganisiwe ye-P/ABS igcina izinzuzo zakho kokubili; I-PC/ABS inobulukhuni obuphezulu bobuso, ukuqina okuphezulu nokuqina, nokumelana nokucindezeleka okukhulu kokuqhekeka; Izakhiwo zayo zemishini zisendaweni ethile phakathi. Ingxubevange ye-PC/ABS kudeshibhodi yemoto, isibambo somnyango, ubakaki, ishede yekholomu yokuqondisa, ipuleti lokuhlobisa, izesekeli zesistimu ye-air conditioning, ikhava yesondo lemoto, igobolondo elikhanyayo, i-lampshade nezinye izindawo eziningi.

Ukuthuthukiswa kwesikhathi esizayo kwamapulasitiki ezimoto

Ukwenyuka kwesidingo sabathengi sezimoto ezonga uphethiloli, ezihlala isikhathi eside futhi ezingasindi kuzogqugquzela isidingo samapulasitiki embonini yezimoto. Phakathi kwamapulasitiki asetshenziswa ezimotweni, izinga lokusebenzisa amapulasitiki ajwayelekile (njenge-PP, i-PE, i-PVC, i-ABS, njll.) libalelwa ku-60%, kuyilapho izinga lokusebenzisa amapulasitiki obunjiniyela (njenge-PA, i-PC, i-PBT, njll. .) Ibalelwa ku-18%. Ngakho-ke, ezimotweni zanamuhla, kungakhathaliseki ukuthi umhlobiso wangaphakathi, umhlobiso wangaphandle, noma isakhiwo sokusebenza semoto, inani elikhulu lezingxenye seziqalile ukusebenzisa izingxenye zepulasitiki esikhundleni sezingxenye zensimbi, okungukuthi, insimu yezimoto "yepulasitiki esikhundleni salokho." of steel” umkhuba odlangile.
