Ukulungiswa kwe-bumper plastic

Ukuqhekeka kwezinto zepulasitiki kuvamile, ikakhulukazi uma kungubhampa. Izimoto zesimanje zifakwe amabhampa epulasitiki. Uma kumnyama ngaphandle namawindi emotweni anombala, kulula kakhulu ukungasiboni isithiyo bese ushayisa kuso, isibonelo, ukwenza isipele.

Ngokuya ngohlobo lomonakalo, le ngxenye ingalungiswa esikhundleni sokuthenga okusha. Cabanga ukuthi ungalungisa kanjani ama-bumpers epulasitiki, nokuthi yiziphi izinto namathuluzi afanele lokhu.

Ukuhlukaniswa kokulimala kwebhampa lepulasitiki

Ukulimala kwepulasitiki kuncike emandleni omthelela, nakwisakhiwo sendawo lapho imoto ixhunywe khona. Izinto ezisetshenziswa abakhiqizi zingahluka, ngakho-ke uhlobo lomonakalo luyahlukahluka. Kwezinye izimo, umenzi akavumeli ukulungiswa kukabhampa, kokunye lokho kuvunyelwe.

Uma zonke izinhlobo zokulimala kwama-bumpers epulasitiki zihlukaniswe ngezigaba, uthola izinhlobo ezine:

• Scratch. Lolu hlobo lomonakalo lulungiswa kalula ngokufaka amabala. Kwesinye isikhathi ukuklwebheka akujulile futhi kwanele ukukupholisha. Kwezinye izimo, umonakalo ujulile, futhi ushintsha kancane isakhiwo sendawo esizeni somthelela (ukusika okujulile).
• Ukuqhekeka. Zenzeka ngenxa yokushaywa okunamandla. Ingozi yalolu hlobo lomonakalo ukuthi kwesinye isikhathi kungaba nzima ukuyibona ngokuhlola okubukwayo. Uma kwenzeka kuqhekeka u-bumper, abakhiqizi abancomi ukuthi basebenzise ingxenye, kepha esikhundleni sayo bafake entsha. Inkinga ingabhebhetheka ngokudlidlizela okudluliselwa emzimbeni njengoba imoto ihamba, okungakhuphula usayizi wokuqhekeka, okungadala ukuthi ucezu olukhulu lweplastiki lunqamuke.
• Isifaca. Ngokuya ngendaba okwenziwe ngayo ubhampa, umonakalo ungathatha uhlobo lwesifaca endaweni yomthelela oqinile womshini. Lolu hlobo lomonakalo luzohlala luhlanganisa imihuzuko nemifantu.
• Ngokuwohloka, ukukhalipha. Lolu uhlobo lomonakalo oluyinkinga kakhulu, njengoba ukulungisa indawo elimele kungaba nzima ukungabi bikho kocezu oluncane lweplastiki olungatholakali. Umonakalo onjalo uvela ngenxa yokushayisana kwephuzu noma umthelela ku-engeli ebukhali.

Uhlobo ngalunye lomonakalo ludinga ukulungiswa kwalo kwe-algorithm. Ezimweni ezimbili zokuqala, inkinga isuswa ngopende nopholishi. Ake sicabangele ukuthi ungalungisa kanjani umonakalo omkhulu kakhulu.

Ungalungisa kanjani u-bumper ukuze ulungiswe

Ngaphambi kokuqhubeka nokubuyiselwa kukabhampa, kufanele isuswe emotweni. Kulokhu, kubaluleke kakhulu ukuthi uqaphele ukuze ungalimazi ingxenye ngokuphelele.

Isinyathelo esilandelayo, esizosiza ukulungisa kahle into yokulungisa, ukuyihlanza ekungcoleni. Njengoba inqubo yokubuyisela izosebenzisa izinto ezinamathelisi, indawo kufanele ihlanzeke ngangokunokwenzeka. Ukwenza lokhu, ungasebenzisa noma isiphi isepha. Kubalulekile ukuthi iqukathe izinhlayiya ezilimazayo, ngaphandle kwalokho umsebenzi wepende uzokwehla.

Umsebenzi wokupenda ususwa kuphela endaweni ethintekile. Ngaphezu kwalokho, ukuhlubula kufanele kwenziwe kokubili kusuka ezinhlangothini zangaphambili nangemuva. Ingaphezulu elikhudlwana kufanele lihlanzwe, hhayi ilunga uqobo. Ibanga lamasentimitha amabili ohlangothini ngalunye lanele.

Yize abashayeli abaningi bebiza ipulasitiki enkulu noma ipulasitiki, empeleni, kunezinto ezahlukahlukene zokwakha lezo zingxenye. Kokunye, ngeke kube nzima ukwenza ukulungiswa kwekhwalithi ephezulu, futhi kokunye, izingxenye zimane nje zingabopheki. Okubonakalayo kungabonakala kumaka ngemuva kukabhampa. Incazelo yezimpawu ingatholakala ku-Intanethi.

Uma umenzi enganikezanga lolu lwazi, ezimweni eziningi ubhampa wenziwa nge-fiberglass. Uma ingashintshiwe kusuka kwimboni, imininingwane ngqo kulolo lwazi ingatholakala kwimininingwane esemthethweni yomkhiqizi, ekhonjiswa ezincwadini zobuchwepheshe.

Isisetshenziswa Sokulungisa Ubhampa

Ngaphambi kokuthatha isinqumo ngethuluzi, udinga ukuhlela ukuthi iyiphi indlela ezosetshenziswa: ukugoqa noma ukunamathisela.

Ukulungisa u-bumper ngokushisela, uzodinga:

• Insimbi yokugcoba (40-60 W);
• Ummese;
• Ukwakha isomisi sezinwele;
• Isigaxa;
• Okuyisisekelo, i-scotch tape;
• Izikele zensimbi;
• Shayela nge-drill encane;
• Isikhafu se-Flat.

Ukugcwala kudinga amakhono, ngakho-ke kwabaqalayo, umphumela awubukeki uhle ngaso sonke isikhathi. Kulula ukunamathisela u-bumper. Kulokhu, uzodinga:

• Hhawu;
• Izitishi noma intambo yenayiloni (ukulungisa izingxenye ezizoxhunywa);
• I-fiberglass;
• Isinamathelisi (kufanele sicaciswe ukuthi izinto ezi-bumper zizosabela kanjani kuso). Kungaba yi-epoxy noma i-polyester.

Ubuchwepheshe bokulungisa ubhampa

Ukuvikela ukuqhekeka ukuthi kungasabalali ngesikhathi senqubo yokulungisa, kufanele kwenziwe izimbobo ezincane emaphethelweni azo. Lokhu kwenziwa nge-drill encane kunazo zonke. Okulandelayo, zombili izingxenye zixhunyiwe, futhi zinanyathiselwe ndawonye nge-tape ebonakalayo evela ngaphandle.

Ngensimbi eshisayo e-soldering, sidweba kusuka ngaphakathi eceleni komfantu (umgodi ongajulile kufanele wakheke). Ngenxa yokuncibilika, imiphetho ixhunywe ngokuqinile komunye nomunye. Isinyathelo esilandelayo sihlanganisa. Ukwenza lokhu, ungasebenzisa ukudla okuyisisekelo kwefenisha.

Inhlayiya yensimbi ibekwa kupulasitiki oncibilikisiwe ukuze onqenqemeni olulodwa lube sengxenyeni eyodwa, bese kolunye uhlangothi. Insimbi izogqwala ngokuhamba kwesikhathi, ngakho-ke kufanele uzame ukumboza okuyisisekelo ngepulasitiki. Lolu uhlobo lokuqiniswa komthungo.

Lapho usebenza ngensimbi oku-soldering, kudingeka uqaphele ukuze ungashisi ngepulasitiki. Inqubo efanayo yenziwa ngaphambili kobhampa. Umehluko kuphela ukuthi azikho izisekelo ezisetshenziswayo kulolu hlangothi.

Manje udinga ukusika imichilo yempahla. Kulokhu, ukuze ulungise ingxenye, uzodinga isomisi sezinwele. Kufanele ibe nombhobho oyisicaba lapho kuzofakwa khona amapheshana epulasitiki (leyo nto kufanele ifane naleyo ingxenye uqobo eyenziwe ngayo).

Inketho ekahle kunazo zonke yokwenza inqubo kungaba ukulungiswa komnikeli ofanayo. Imichilo yobubanzi obufanele iyasikwa kuyo kusetshenziswa isikele sensimbi.

Okokuqala, ohlangothini lwangemuva, udinga ukuhlola isikimu somsebenzi ukuze ungonakalisi ingaphambili lomkhiqizo. Izinto ezikhethwe ngokufanele ngeke zivele ngemuva kokuphulukiswa. Ukulungisa imifantu emikhulu, indawo ezokwelashwa ihlukaniswe phakathi. Okokuqala, umugqa omfushane ushiselwe phakathi. Ngemuva kwalokho ingxenye ngayinye ibuye ihlukaniswe kabili. Ucezu oluncane lwe-electrode lufakwa phakathi. Ngemuva kwalokho izikhala ezisele ziyagcwaliswa.

Okungahambi kahle okuholelekile kususwa ngomshini wokugaya (usayizi we-grit P240). Ukugwema ukususa ipulasitiki eningi engxenyeni okunzima ukuyifinyelela, ungasebenzisa i-sandpaper noma uvale umthungo nge-plastic putty. Izinwele ezinhle ezenziwe ngemuva kokucutshungulwa nge-sander zingasuswa ngomlilo ovulekile (isibonelo, i-lighter).

Ukusebenza ngezinto ezahlukahlukene kunobuhlakani babo.

Imithetho yokulungisa ngokuvula izingxenye ze-polypropylene

Uma okokusebenza okwenziwe yingxenye iyi-polypropylene, nakhu okufanele ucabangele ngaphambi kokwenza ukulungiswa:

• Ububanzi be-electrode kufanele bube cishe ngo-3-4 mm;
• Umgodi ohambisanayo kufanele ube semlomo wombhobho wokomisa izinwele;
• Kubaluleke kakhulu ukwazi izinga lokushisa lapho i-polypropylene incibilika khona. Okubalulekile yi-thermosetting, ngakho-ke, ezimweni ezithile, kungalahlekelwa yizakhiwo zayo. I-electrode kufanele incibilike ngokushesha. Kulokhu, akufanele ivunyelwe ukushisa ngokweqile, ngaphandle kwalokho izolahlekelwa yimpahla yayo;
• Ngaphambi kokumboza ukuqhekeka, umsele omise okwe-V kufanele wenziwe emaphethelweni awo. Ngakho-ke okubalulekile kuzogcwalisa isikhala futhi ngeke kuxebuke ngemuva kokucutshungulwa kokuhlobisa.

Imithetho yokulungisa ngokuvula izingxenye ze-polyurethane

Uma u-bumper wenziwe nge-polyurethane, izimo ezibalulekile zizoba:

• Okuqukethwe kunwebeka impela, ngakho-ke kufanele futhi usebenzise okuyisisekelo. Njengasesimweni sokufaka isondo okuchazwe ngenhla, insimbi kufanele imbozwe ngokuphelele ukuze ingagqoki.
• I-polyurethane yi-thermoset futhi iyancibilika kuma-degree angu-220. Uma lo mkhawulo weqiwe, okokusebenza kuzobilisa futhi kulahlekelwe yimpahla yayo.
• Ukulungisa lezo zingxenye, kudingeka amapheshana angaba ngu-10 mm ububanzi. Umbhobho wokomisa izinwele kufanele ube nosayizi ofanayo.

Lungisa ngokunamathisela

Lokhu kungenye yezindlela ezilula kakhulu, futhi ngasikhathi sinye, ezinesibopho sokulungisa ababhampa. Endabeni yepulasitiki eqinile, i-soldering ayisetshenziswanga, ngoba leyo nto inendawo encibilika kakhulu (cishe ama-degree angama-5000).

Ukulandelana kokulungiswa kwalezi zingxenye kanje:

1. Ngosizo lwe-sander, imiphetho yezingxenye ezizohlanganiswa isheleliswa ukuze isuse ilinti elincane elenziwe ngemuva kokuphuka.
2. Womabili amahafu ahlanganisiwe alungiswa nge-tape yokunamathisela. Ukuvikela ifilimu ekuphazamiseni ukunamathela kwe-fiberglass, abaningi basebenzisa intambo yokwenziwa. Kubalulekile ukunquma ukuthi izosabela kanjani ekwakhiweni kwamakhemikhali kokunamathiselwe. Ukulungisa izingxenye ezizofakwa, kunezimbobo ezincanyana kuzo, lapho kufakwa khona intambo (noma kufakwe ubakaki). Omunye umkhawulo wentambo ubekwe eceleni komsele owenziwe, kanti omunye umkhawulo "uthungwa" isigaba sonke. Kubalulekile ukuthi lapho kuqiniswa izakhi, ilunga alikhubazi, ngaphandle kwalokho ubhampa uzophenduka agwegwile.
3. Okulandelayo, i-glue ilungisiwe (uma iqukethe izinto eziningana) ngokuya ngemiyalo.
4. I-adhesive isetshenziswa ngaphakathi ngaphakathi kulo lonke ukuqhekeka. Indawo ezokwelashwa kufanele ibe ububanzi obungamasentimitha amahlanu ohlangothini ngalunye.
5. I-fiberglass isetshenziselwa ukunamathela. Isendlalelo kufanele sikhuliswe kuze kufinyelele ezingeni lokuthi silingana nendiza yayo yonke ingxenye kabhampa (uma kwenziwa isifaca ngenxa yomthelela).

Lapho ingaphakathi selomile, ungaqhubeka usebenze kwenye ingxenye. Inqubo yobuso iyafana, kuphela umthungo okufanele uqiniswe ngaphambi kokunamathisela i-fiberglass. Ukwenza lokhu, i-groove yenziwa eceleni komfantu, ogcwele ingxube ye-fiberglass ne-glue.

Isigaba sokugcina sokulungisa siwukuncoma nokudweba umkhiqizo ngombala ofanele.

Umphumela

Ukulungisa u-bumper owonakele kungenziwa ekhaya. Uma kunokungabaza ukuthi umsebenzi uzokwenziwa kahle, kufanele ucele usizo lomuntu osevele enze inqubo efanayo.

Ezitolo ezidayisa izimoto ungathola amakhithi akhethekile wokulungisa amabhampa. Kuzoba kushibhile kunokuthenga ingxenye entsha.

Imibuzo nezimpendulo:

Indlela yokulungisa umfantu kubhampa wepulasitiki? Vala ukuqhekeka nge-polymer ewuketshezi; i-solder ngenduku; i-solder nge-dryer yezinwele zokwakha; i-glue nge-fiberglass; glue nge-adhesive izingxenye ezimbili.

Uwulungisa kanjani ubhampa oqhekekile? Lungisa imiphetho yokuqhekeka (usebenzisa ama-clamp noma i-tape yokwakha). Ekupheleni komonakalo, sebenzisa (i-ABS plastic), degrease futhi uhlanze imiphetho. Glue.

Yini oyidingayo ukuze ulungise ibhampa? Insimbi enamandla ye-soldering noma isomisi sezinwele zokwakha; Mesh yensimbi yokuqinisa imiphetho; isiqalo; i-putty; sandpaper yobukhulu obuhlukahlukene bokusanhlamvu; udayi.
