Ndeapi mabhampa emota akagadzirwa: maitiro ekuona izvo zvinhu iwe pachako
Zviri mukati
Zvishoma kashoma, thermosetting zvinhu zvinoshandiswa sepurasitiki kune bumper pamotokari. Havagoni kutambanudzwa kana kunyungudutswa. Pakati peizvi, zvinonyanya kushandiswa zvinogadzirwa, zviri mukamuri yejini padyo nejini.
Kana kuzvigadzirisa zvikamu zvemuviri zvakakuvadzwa nekuda kwetsaona kana kushanda kwenguva refu kwemotokari, mubvunzo unova wakakosha kune varidzi: ndeapi mapurasitiki mabumpers emotokari akagadzirwa. Izvi zvichange zvichidikanwa panguva yekugadzirisa mabasa, kudzorera nhengo dzemuviri nemaoko ako pachako.
Izvo zvinhu izvo mabhampa emotokari anogadzirwa
Mhando dzemotokari dzemazuva ano dzakashongedzerwa nemabhampa epurasitiki akachipa. Makiti emuviri akadaro haatambure ne ngura, anonyanya kutora kuvhunduka.
Durable plastic bumper
Vagadziri vemichina vanoshandisa thermo- uye thermoset mapurasitiki.
Vokutanga vanosiyaniswa nechokwadi chokuti pasi pesimba rekushisa kwepamusoro vanotanga kunyunguduka. Iwo ekupedzisira haasi pasi peizvi, ndiko kuti, haashanduri mamiriro avo kubva pakupisa.
Imwe yakanyatsokodzera zvinhu kubva kune mabumpers emotokari inogadzirwa thermoplastic, iyo inonyunguduka nyore, iyo inobvumira mutyairi kugadzirisa kititi chemuviri kana paine zviratidzo zvekukuvadza kana kupfeka kwechisikigo. Nzvimbo dzakarapwa dzinoomesa zvakare mushure mekutonhora.
Dzimwe nguva zvinhu zvebumper yemotokari musanganiswa wemapurasitiki. Kana uchibatanidza marudzi akasiyana-siyana emapurasitiki, chinhu chitsva, chakasimba uye chakasimba chinowanikwa, kubva pacho mabumpers anogadzirwa pamotokari. Kuti vagadzirise chitarisiko chemotokari, vatyairi vanowanzoita makiti emuviri: zvese kumberi nekumashure. Unyanzvi hwepamusoro pakushandura chitarisiko chemotokari ndiyo yakazvimirira kugadzirwa kwepurasitiki bumper yemotokari. Izvi zvinogona kuitwa uchishandisa zvinhu zvakakurumbira.
Polycarbonate
Polycarbonate chinhu chisina analogues pakati anozivikanwa thermoplastics. Nyaya yacho haina kukanganiswa zvachose nemamiriro ekunze. Chinhu chayo chikuru ndechekudzivirira kwechando. Humwe hunhu:
- simba;
- flexibility;
- lightness;
- moto kuramba;
- durability.
Polycarbonate bumper
Polycarbonate ine yakakwirira yekupisa yekupisa zvivakwa, nepo yakanyanya tembiricha yekushanda iri kubva -40 kusvika 120 degrees Celsius.
fiberglass
Fiberglass inoreva zvinhu zvakaumbwa. Zviri nyore kugadzirisa, zvinopesana nekunyanyisa kwekushisa. Iyo fiberglass yakamisikidzwa neresin. Iine kuomarara kukuru, iyo inokanganisa kusununguka kwekuisa uye kusimba mukushanda: kurova mupendero kana kubata zvishoma fence kunoparadza chikamu chisina kusimba chekiti chemuviri. Panguva imwecheteyo, tekinoroji yakakodzera iyi inosanganiswa inofanirwa kuiswa pakugadzirisa. Mune zvimwe zviitiko, chikamu chinofanira kunamirwa, mune vamwe chinofanira kuve chakasungwa.
Fiberglass bumper
Iyo yakakuvadzwa fiberglass body element inogona kugadziriswa seinotevera:
- chenesa uye sukurudza pamusoro;
- gadzira mipendero yezvimedu nekubviswa kwetambo dzakaputika dzezvinhu neguyo;
- dock zvinhu pamwe chete uye zvigadzirise ne glue;
- shandisa polyester resin kune kuputika;
- isa iyo fiberglass yakanamirwa neglue pakuzorora;
- mushure mekutonhora, geda;
- putty nzvimbo yakarapwa, degrease, prime muzvikamu zviviri;
- pendi pamusoro.
Mushure mekugadzirisa, zvinokurudzirwa kuti usageze motokari mumhepo yakanyanyisa kushambidza kwemavhiki mashoma.
Polypropylene
Iri rudzi rwepurasitiki, inonzi "PP", ndiyo inonyanya kushandiswa kwepurasitiki yekugadzira mabumpers pamotokari - ine yakakwirira kupfeka kusagadzikana, simba uye ndiyo inonyanya kukodzera kugadzirwa kwekiti yemuviri mitsva yemotokari.
Polypropylene bumper
Zvigadzirwa zvakagadzirwa kubva kune iyi elastic zvinhu zvinotora zvinokatyamadza: makumbo evanhu achakuvara zvishoma kana arohwa. Plastiki haina kunamatira kune zvimwe zvinhu.
Nzira yekuziva kuti bumper yemotokari yakagadzirwa sei
Kuti ugadzirise zvakanaka kititi chemuviri chakakanganisika, iwe unofanirwa kuziva kuti ndeupi rudzi rwemota bumper zvinhu zvaunofanira kubata nazvo. Kuti uite izvi, tsvaga mavara ari kumashure kwechikamu chepurasitiki.
Panogona kana kusave nekodhi pachigadzirwa. Mumamiriro ezvinhu akadaro, ita muedzo unotevera kuti uone plastiki.
Cheka mutsara wakamanikana kubva panzvimbo isingaoneki. Ichenese kubva papende, tsvina. Isa iyo inoguma "isina" plastiki mumudziyo wemvura. Kana chidimbu chakachekwa chikasaenda pasi, saka une thermoplastic (PE, PP, + EPDM) - chinhu icho makiti mazhinji emuviri anogadzirwa. Aya mapurasitiki anoyangarara pamusoro pemvura sezvo density yavo kazhinji isingasviki imwe. Zvishandiso zvine humwe hunhu zvinonyura mumvura.
Imwe nzira yekuziva kuti ndeyeimwe rudzi rwepurasitiki ndeyekuedza moto. Ongorora kukura kwemurazvo, ruvara uye rudzi rweutsi. Saka, polypropylene inopisa nemoto webhuruu, uye utsi hune hutu hunopinza, hunotapira. Polyvinyl chloride ine moto unopfungaira; kana yapiswa, chinhu chitema, semarasha chinoumbwa. Muedzo haupi mhedzisiro chaiyo nekuda kwekuti zvinhu zvacho zvine zvakasiyana-siyana zvinowedzera.
