Ngabe ngidinga ukumisa imoto ngaphambi kokufaka i-putty?

I-Putty - ukwakheka okunefomu lepulasitiki futhi lenzelwe ukugcwalisa imigodi eyenziwe ngenxa yokulimala kwento. Ngenxa yezici zesenzo sezingxube ze-primer kanye ne-putty, ukuhleleka kwesicelo sabo kuyahluka - okokuqala, amaphutha amakhulu aqedwa, khona-ke ukwakheka kusakazwa, okuqinisekisa ukunamathela okuthembekile kopende kanye nendawo ephathwayo.

Lapho benza ukulungiswa komzimba bebodwa, abanye abashayeli bezimoto abazi ukulandelana okulungile kwezenzo, bengabaza ukuthi i-primer noma i-putty isetshenziswa kuqala emotweni. Sizothola ukuthi ochwepheshe bacubungula kanjani umzimba wemoto.

Umehluko phakathi kwe-primer ne-putty

Inhloso eyinhloko ye-primer ukuthuthukisa ukunamathela phakathi kwezingqimba ezisetshenzisiwe zopende (LCP). Ngaphezu kwalokho, yenza eminye imisebenzi:

• Isusa amabhamuza omoya emaphutheni amancane endaweni ephathwayo (imihuzuko, ama-chips, angabonakali ngeso lenyama).
• Isebenza njengengxenye yokuxhuma yezendlalelo ezingahambisani kahle nezinye futhi ezingangena ekusabeleni kwamakhemikhali, bese kucwecwa.
• Ivikela emathonyeni angaphandle - ukuthintana namanzi, umoya, isihlabathi nezinye izinto. Ngenxa yokuthi i-primer ivimbela ukufinyelela kwangaphandle kwensimbi, ukwakheka kokugqwala akufakiwe.

I-Putty - ukwakheka okunefomu lepulasitiki futhi lenzelwe ukugcwalisa imigodi eyenziwe ngenxa yokulimala kwento. Ngenxa yezici zesenzo sezingxube ze-primer kanye ne-putty, ukuhleleka kwesicelo sabo kuyahluka - okokuqala, amaphutha amakhulu aqedwa, khona-ke ukwakheka kusakazwa, okuqinisekisa ukunamathela okuthembekile kopende kanye nendawo ephathwayo.

Ukulungiswa komzimba wemoto

Ngabe ngidinga ukucubungula ngaphambi kokubeka i-putty

Ubuchwepheshe bokucubungula izingxenye zomzimba ngaphambi kokudweba akubandakanyi ukucubungula ngaphambi kokusebenzisa i-putty. Ukwakheka kokuxazulula inkinga kuhloswe ukuthi kusetshenziswe insimbi "engenalutho", ukunamathela okuhle kufinyelelwa ngokungeza izingxenye ezikhethekile kuyo.

Ukumisa imoto ngaphambi kokufaka i-putty kuvunyelwe kuphela uma ingxube iqukethe i-epoxy. Abapendayo benza lokhu lapho belungisa izitho zomzimba isikhathi eside. Ngokuvamile, umsebenzi wokubuyisela nokubuyisela uthatha isikhathi eside. Lapho insimbi ivezwa emoyeni ovulekile, ezimweni zomswakama ophezulu, izinqubo zokugqwala ziyasebenza.

Izitolo zokukhanda izimoto ezichwepheshile nazo ziqala imoto ngaphambi kokufakwa kwe-putty. Lokhu kwenziwa ukuze kuqinisekiswe ukuthi ngaphansi kwanoma yiziphi izimo, ukugqwala kwensimbi ngeke kuvele.

Kuvunyelwe ukukhipha insimbi ngaphambi kokufaka imoto ize yome ngokuphelele. Izingxenye ezakha amathuluzi womabili ziyasebenzisana futhi zixhumeke ngokuqinile. Ukuze kuthuthukiswe ukunamathela, ingaphezulu lihlanzwa kancane ngokususa izakhi eziphumayo.

Kungenzeka yini ukufaka i-putty emsebenzini wokupenda omdala

I-Puttying upende omdala kunengqondo uma kukhona ukukhathazeka mayelana nokubukeka kokugqwala isikhathi esifushane ngemva kokwelashwa. Ukuze uthuthukise ukunamathela, kunconywa ukuphatha upende nge-sandpaper, unikeze i-porosity. Ngemuva kwalokho i-putty izongena kulawa ma-pores futhi inamathele ngokuqinile.

Inqubo yokufaka i-putty kumdwebo omdala:

1. Hlanza ubuso obuzophathwa ezindaweni ezinenkinga - susa upende ovuvukile, amabala e-bituminous, njll.
2. Gcoba ingxenye yomzimba nge-solvent, utshwala.
3. Lungisa amaphutha akhona.

Kungenzeka ukusebenzisa ukwakheka kwe-putty kuphela kupende osesimweni esihle - awunayo imifantu, ama-chips, noma ama-flaking. Uma kukhona ukukhubazeka ngobuningi obukhulu, kungcono ukuhlanza umdwebo omdala endaweni yensimbi.

Indlela yokukhetha i-putty efanele, izici zohlelo lokusebenza

Ukwakheka kwe-putty kukhethwa kuye ngenkinga yesici somzimba esicutshunguliwe. Izinhlobo zama-putty ziyahlukahluka komunye nomunye kusithako esisebenzayo:

• I-Fiberglass. Zisetshenziselwa ukuqeda amaphutha amakhulu, njengoba imicu ye-fiberglass inesakhiwo esinzima, idinga ukugaya okulandelayo kanye nokusetshenziswa kwesendlalelo sokuqeda. Izinto ezinjalo zibonakala ngokwakhiwa kwendawo yokulungisa eqinile, ephikisana nokulimala ngisho nangaphansi komthwalo osindayo.
• Ngezinhlamvu ezinkulu. Isetshenziselwa ukwelashwa okungalungile kwezindawo ezinomonakalo omkhulu. Ihlukile ngepulasitiki kanye nezindawo ezibekwe kahle okunzima ukufinyelela kuzo. Ngenxa yokuba khona kwezingxenye ezinkulu ekubunjweni, i-primer ayinciphisi futhi ibonakala ngokunyuka kokunamathela.
• Ngezinhlamvu ezinhle. Abanye abadwebi bakubiza ngokuthi ukuqeda, njengoba kusetshenziselwa ukulungisa amaphutha amancane. I-primer ehlanjululwe kahle icutshungulwa kalula nge-sandpaper, ayikho imihuzuko noma ezinye iziphambeko ezibonakalayo ebusweni. I-primer ifanele ukugcwalisa insimbi kuphela, kodwa futhi ipulasitiki, izakhi ze-fiberglass.
• I-Acrylic esekelwe. Isakhiwo asifani ne-putty evamile - ukwakheka kwe-acrylic kuwuketshezi, ngokubukeka kufana ne-primer. Isetshenziselwa ukugcwalisa izindawo ezinkulu, ipulasitiki futhi kulula ukuyisebenzisa. Umkhiqizi womkhiqizo uvumela ukudweba indawo ephathwayo ngaphandle kokuqalwa kabusha okulandelayo.

Inqubo yokusebenzisa ukwakheka kwe-putty:

1. Hlanza indawo.
2. I-fiberglass-grained (fiberglass) yokugcwalisa ifakwe kuma-pores amakhulu.
3. I-fine-grained noma i-acrylic putty isusa amaphutha amancane.
4. Umsebenzi womzimba odwetshiwe futhi opendiwe.

Abanye abadwebi abasebenzisi ama-coarse-grained aggregates, basusa ukungahambi kahle ngokuqeda i-putty. Lolu khetho luyamukeleka, kodwa izindleko zibiza kakhulu.

Indlela yokukhetha nokusebenzisa i-primer

Ngaphambi kokufaka isicelo, kuyadingeka ukutadisha izinhlobo zezingxube ze-primer, ngoba ububanzi bokusebenza kwazo buhlukahluka kuye ngokuthi inhloso.

Indlela yokugaya i-primer

Izinhlobo zomhlabathi:

• I-epoxy esekelwe. Ibonakala ngesakhiwo esiwuketshezi, kanye nokuqukethwe kwe-chromium. Ihluke ngokumelana nethonya lamakhemikhali anolaka, iphazamisa ukwakheka kokugqwala. I-Epoxy primer ayidingi ukukhumula okwengeziwe ngaphambi kokudweba (ngaphandle uma ukubunjwa kusetshenziswe ngokungalungile futhi kwakhiwa imicu).
• Okuyinhloko. Inhloso enkulu ukuvikela ukugqwala kwezindawo ezithintana ngqo namanzi. Kuvunyelwe ukusebenzisa i-primer ngaphambi kokubeka imoto.
• Kuvaliwe. Iqeda ukuthintana phakathi kwezingqimba ezimbili zopende kanye ne-varnish futhi ayivumeli umthelela omubi womunye komunye (upende ungase ube nama-chemical compounds anolaka abhubhisa i-putty).

Inqubo yokufaka isicelo:

1. Hlanza amaphutha abonakalayo ku-putty ngokususa izakhi eziphumile.
2. Gcoba indawo ephathwayo nge-solvent, utshwala, uphethiloli.
3. Faka i-primer ngezigaba eziningana, phakathi kwazo zonke kudingeka uthathe ikhefu okungenani imizuzu engu-90 ukuze wome.

Unganquma ukuthi ungqimba olulandelayo lomile ngokubukeka kwalo - luzoba buthuntu futhi lube lukhuni kancane.

Yikuphi okungcono - ukubeka imoto noma ukubeka imoto

Umbuzo ofanayo ubuzwa abaqalayo ebhizinisini lokudweba. Abayiqondi ngokugcwele inhloso yazo zombili izingoma futhi abawuboni umehluko ekusebenzeni. Nakuba abanye abakhiqizi be-primer bevumela ukusetshenziswa kwabo ensimbi engenalutho, akuwona wonke umkhiqizo okwazi ukuqeda amaphutha akhona emsebenzini wokupenda. Ukugcwalisa ama-craters amakhulu ngaphandle kokusebenzisa i-putty akunakwenzeka, ngakho-ke, lapho ukhetha isigcwalisi sokucubungula isici ngasinye somzimba, kuyadingeka ukuya kuso ngamunye.

Ungayilungisa kanjani futhi kanjani insimbi ngaphambi kokufaka i-putty
