Ama-bumpers emoto enziwe ngani: indlela yokunquma impahla ngokwakho
Okuqukethwe
Akuvamile, izinto zokubeka i-thermosetting zisetshenziswa njengepulasitiki kubhampa emotweni. Angeke zelulwe noma zihlakazwe. Kulokhu, izinto ezisetshenziswayo ikakhulukazi zenziwe, ezitholakala endaweni yenjini eduze kwenjini.
Lapho izingxenye zomzimba ezizilungisayo zonakaliswe ngenxa yezingozi noma ukusebenza isikhathi eside kwezimoto, umbuzo uba ngofanelekile kubanikazi: yimaphi amapulasitiki amabhampa ezimoto enziwe ngawo. Lokhu kuzodingeka ngesikhathi sokulungisa, ukubuyisela izingxenye zomzimba ngezandla zakho.
Izinto okwenziwa ngazo obhampa bezimoto
Izinhlobo zezimoto zesimanje zifakwe obhampa bepulasitiki abashibhile. Amakhithi omzimba anjalo awahlushwa ukugqwala, athatha ngempumelelo ukushaqeka.
Ubhampa wepulasitiki oqinile
Abakhiqizi bemishini basebenzisa ipulasitiki ye-thermo- ne-thermoset.
Abokuqala bahlukaniswa yiqiniso lokuthi ngaphansi kwethonya lokushisa eliphezulu baqala ukuncibilika. Lezi zokugcina azikho ngaphansi kwalokhu, okungukuthi, azishintshi isimo sazo ekushiseni.
Into efanelekile kakhulu okwenziwa ngayo amabhampa emoto i-thermoplastic, encibilika kalula, okuvumela umshayeli ukuba alungise ikhithi yomzimba uma kunezimpawu zokulimala noma ukugqokwa kwemvelo. Izindawo ezilashwayo ziyaqina futhi ngemva kokupholisa.
Kwesinye isikhathi izinto zikabhampa wemoto ziyingxube yamapulasitiki. Ngokuhlanganisa izinhlobo ezahlukene zamapulasitiki, kutholakala into entsha, enamandla kakhulu futhi eqinile, lapho kwenziwa khona amabhampa ezimotweni. Ukuze kubuyekezwe ukubukeka kwemoto, abashayeli bavame ukushuna amakhithi omzimba: kokubili ngaphambili nangemuva. Ikhono eliphezulu ekushintsheni ukubukeka kwemoto ukukhiqizwa okuzimele kwe-plastic bumper yemoto. Lokhu kungenziwa ngokusebenzisa izinto ezithandwayo.
I-Polycarbonate
I-Polycarbonate iyinto engenawo ama-analogues phakathi kwe-thermoplastics eyaziwayo. Indaba ayithinteki ngokuphelele izimo zezulu. Impahla yayo eyinhloko ukumelana nesithwathwa. Ezinye izimfanelo:
- amandla;
- ukuguquguquka;
- ukukhanya;
- ukumelana nomlilo;
- ukuqina.
Ibhampa ye-Polycarbonate
I-Polycarbonate inezinto eziphezulu zokushisa ezishisayo, kuyilapho izinga lokushisa eliphezulu lokusebenza lisuka ku--40 kuya ku-120 degrees Celsius.
i-fiberglass
I-Fiberglass ibhekisela ezintweni ezihlanganisiwe. Kulula ukuyicubungula, imelana nezinga lokushisa elidlulele. I-fiberglass ehlanganiswe ne-resin. Inokuqina okukhulu, okuthinta kalula ukufakwa nokuqina ekusebenzeni: ukushaya unqenqema noma ukuthinta kancane ucingo kubhubhisa ingxenye ebuthakathaka yekhithi yomzimba. Ngesikhathi esifanayo, kufanele kusetshenziswe ubuchwepheshe obufanele le nhlanganisela ethile ukuze bulungiswe. Kwezinye izimo, ingxenye kufanele inandiswe, kwezinye kufanele ihlanganiswe.
I-Fiberglass bumper
Isici somzimba esilimele se-fiberglass singalungiswa ngale ndlela elandelayo:
- hlanza futhi ugeze ubuso;
- cubungula imiphetho yokuqhekeka ngokususa imicu ephumayo yezinto nge-grinder;
- hlanganisa izakhi ndawonye futhi uzilungise ngeglue;
- sebenzisa i-polyester resin ekuqhekekeni;
- beka i-fiberglass efakwe ngeglue endaweni yokuphumula;
- ngemva kokupholisa, gaya;
- i-putty indawo ephathwayo, degrease, prime in a couple of layers;
- penda ngaphezulu.
Ngemuva kokulungiswa, kunconywa ukuthi ungayigezi imoto ekugezeni okuphezulu amasonto ambalwa.
Polypropylene
Lolu hlobo lwepulasitiki, olubizwa ngokuthi "i-PP", luyipulasitiki evame kakhulu ekwenzeni ama-bumpers emoto - inokumelana nokugqoka okuphezulu, amandla futhi ifaneleka kakhulu ukukhiqizwa kwemishini emisha yomzimba yezimoto.
Ibhampa ye-polypropylene
Imikhiqizo eyenziwe ngale nto enwebekayo imunca imithelela: umonakalo omncane uzobangelwa emilenzeni yabantu lapho ishaywa. Ipulasitiki ayinamatheli kahle kwezinye izinto.
Unganquma kanjani ukuthi i-bumper yemoto yenziwe ngani
Ukuze ulungise kahle ikhithi yomzimba eyonakele, kufanele wazi ukuthi hlobo luni lwempahla yemoto okufanele ubhekane nayo. Ukuze wenze lokhu, thola izinhlamvu ezingemuva kwengxenye yepulasitiki.
Kungase kube khona noma kungabi khona ikhodi emkhiqizweni. Ezimweni ezinjalo, yenza ukuhlolwa okulandelayo ukukhomba ipulasitiki.
Sika umucu omncane endaweni engabonakali. Hlanza kusuka kupende, ukungcola. Beka ipulasitiki "engenalutho" ephumela esitsheni samanzi. Uma ucezu olusikiwe lungangeni phansi, khona-ke une-thermoplastic (PE, PP, + EPDM) - into eyenziwa ngayo amakhithi amaningi omzimba. Lawa mapulasitiki azontanta phezu kwamanzi njengoba ukuminyana kwawo kuvame ukuba ngaphansi kokukodwa. Izinto ezinezinye izici zicwila emanzini.
Enye indlela yokunquma ukuthi ungowohlobo oluthile lwepulasitiki ukuhlola umlilo. Hlola ubukhulu belangabi, umbala kanye nohlobo lwentuthu. Ngakho-ke, i-polypropylene ivutha ilangabi elihlaza okwesibhakabhaka, futhi umusi unephunga elibukhali, elimnandi. I-Polyvinyl chloride inelangabi elishunqayo; lapho ishiswa, kwakheka into emnyama, efana namalahle. Ukuhlolwa akunikezi imiphumela enembile ngenxa yokuthi indaba iqukethe izithasiselo ezihlukahlukene.
