Uyibiza ngokuthini i-back bar foam?
Emkhakheni wezimoto, izinto ezingaphakathi kwebhampa engaphambili akuyona igwebu, kodwa izinto ze-polyethylene ezihlanganisiwe ezingezinhle, ezaziwa nangokuthi ungqimba lwe-foam buffer.
Umsebenzi wayo oyinhloko ukudlala indima ye-buffer ekushayisaneni ngesivinini esiphansi. Isendlalelo se-buffer esisheshayo esiphansi ngokuvamile senziwe nge-polyethylene foam, i-resin engeyona insimbi noma ipulasitiki yobunjiniyela. Indima yayo ukunciphisa umonakalo obhekene nemoto ekushayisaneni ngesivinini esiphansi, futhi ngisho nakwezinye izingxabano ezincane kungaqeda ngokuphelele umonakalo obhekene nemoto.
I-bumper yepulasitiki yakhiwe izingxenye ezintathu, njengepuleti langaphandle, izinto ze-buffer kanye nogongolo. Ipuleti langaphandle nezinto ze-buffer zenziwe ngepulasitiki, kanti ugongolo lwenziwe ngeshidi eligoqwe ngokubandayo elinobukhulu obungaba ngu-1.5 mm futhi lwenziwe umsele omise okwe-U; Ipuleti langaphandle nezinto ze-buffer zinamathele kugongolo, olunamathele kuzikulufu ze-beam longitudinal futhi lungasuswa nganoma yisiphi isikhathi. Ipulasitiki esetshenziswa kule bumper yepulasitiki ngokuvamile yenziwe ngezinto ezimbili, i-polyester ne-polypropylene, futhi yenziwe ngokubumba ngomjovo.
Ingabe kunendaba ukuthi igwebu lokulwa nokushayisana kwemoto lisusiwe?
Umsebenzi oyinhloko we-foam yokulwa nokushayisana kwezimoto ukudlala indima yokubeka i-cushion, uma isusiwe kuzothinta ukusebenza kokuphepha kwezimoto. I-foam yokushayisana ivame ukutholakala ngaphakathi kwama-bumper angaphambili nangemuva ezimoto ukunciphisa ukulimala kwezimoto kanye nabahamba ngezinyawo lapho kushayisana.
Uma igwebu lisuswa, umphumela wokunciphisa imoto uma kwenzeka ingozi uyancishiswa, okwandisa ingozi yokulimala kokubili kubashayeli nakubahamba ngezinyawo. Ngaphezu kwalokho, igwebu elingangeni engozini liyasiza ekunciphiseni izindleko zokulungisa, njengoba ukususwa kungandisa umonakalo kuma-bumper nezinye izingxenye, okuholela ezindleleni zokulungisa eziphezulu.
Ngakho-ke, kunconywa ukuthi ungasusi igwebu elilwa nokushayisana kalula. Uma kunesidingo esikhethekile sokubhidliza, kufanele kucatshangelwe ngokucophelela futhi kuboniswe iseluleko sochwepheshe.
Ubuningi be-foam engashayisani nezimoto buxhomeke ohlotsheni lwezinto ezisetshenziswayo. Isibonelo, ubuningi bebhodi le-foam le-polystyrene eliguquguqukayo (ibhodi le-foam le-EPS) bungu-6kg/m³, kanti ubuningi bebhodi le-foam le-EVA bungafinyelela ku-55g/cm³, okubonisa ukuthi ubuningi be-foam yokulwa nokushayisana kwezimoto bubanzi kakhulu, kuye ngezidingo zomklamo kanye nokukhethwa kwezinto.
Ibhodi le-foam le-polystyrene eliqhumayo (i-EPS) : Le nto inobukhulu obuphansi obungu-6kg/m³ futhi ivame ukusetshenziselwa ukuhlinzeka ngokuvikela okuncishisiwe kanye nokuphahlazeka. Ibhodi le-foam le-EPS lisetshenziswa kabanzi efenisha, ekukhanyeni, ekuthuthweni kwengilazi nakwezinye izindawo ukuqinisekisa ukuphepha kwezinto enqubweni yokuthutha 1.
Ibhodi le-foam le-EVA : elinobukhulu obuphezulu obufika ku-55g/cm³, le nto ivame ukusetshenziswa ezinhlelweni ezidinga ukumelana okukhulu kokushaqeka nokuzamazama komhlaba. Ibhodi le-foam le-EVA elinokusebenza kwalo okuhle kakhulu kokusika, lisetshenziswa kabanzi ezingxenyeni zezimoto, ezintweni zokupakisha nakwezinye izinkambu ukuqinisekisa ukuvikelwa okusebenzayo lapho kushayisana 2.
Ngamafuphi, ubuningi be-foam yokulwa nokushayisana kwezimoto bungakhethwa ngokuya ngezidingo ezithile zezinto ezahlukene kanye nobuningi ukuqinisekisa ukuvikelwa okufanele lapho kushayisana.
