Chitetezo ndi Chitetezo cha Zachilengedwe
Kuti muwonetsetse chitetezo ndi kuteteza chilengedwe mukamaliza kupukuta, tsatirani malangizo awa:
Valani chigoba: Valani chigoba nthawi zonse kuti mudziteteze ku fumbi lochokera mumlengalenga.
Gwiritsani ntchito zida zodzitetezera: Fumbi likhoza kuvulaza khungu mukamagwiritsa ntchito zinthu monga mkuwa, lead, carbon fiber, ndi fiberglass. Valani magolovesi a rabara ndi zovala zodzitetezera kuti khungu lisawonongeke.
Chepetsani kuipitsidwa kwa fumbi: Tinthu ta fumbi tingalowe mosavuta mumlengalenga mukamaliza kupukuta. Ganizirani kugwiritsa ntchito njira yonyowa yopukuta fumbi, monga kupukuta madzi, kuti muchepetse fumbi. Komabe, dziwani kuti kugwiritsa ntchito mphero yamadzi kungayipitse madzi. Gwiritsani ntchito zidebe zosiyana pa gridi iliyonse kuti mupewe kuipitsidwa ndi madzi. Kutaya Moyenera: Tayani zinyalala ndi fumbi moyenera motsatira malamulo am'deralo. Pewani kulola fumbi kulowa m'madzi kapena m'malo ozungulira.
Mpweya wokwanira: Onetsetsani kuti malo opukutira mchenga ali ndi mpweya wabwino kuti fumbi lichepe. Kumbukirani kuti njira zodzitetezera komanso kuteteza chilengedwe ziyenera kuyikidwa patsogolo nthawi zonse popukutira mchenga.
Kusankha ChoyeneraPepala losanjikizaUnyolo wa Zipangizo Zosiyanasiyana
Kupeza maukonde ambiri kungakhale kovuta pazinthu zokhala ndi ulusi monga matabwa ndi chikopa. Ndikofunikira kuyamba ndi maukonde pafupifupi 200 ndikugwiritsa ntchito njira yanu mpaka maukonde 800 kapena 1000 kuti mumalize bwino. Kuti maukonde apamwamba a matabwa ndi chikopa, zinthu zoyambirira ziyenera kukhala zolimba komanso zokhala ndi sera yamafuta. Ndi malo olimba osalala monga galasi, matabwa olimba kapena mkuwa, zilowetseni mu chodzaza mankhwala kuti mumange ulusi ndikuwonjezera kumaliza.
Pazinthu zachitsulo, tikukulangizani kuyamba ndi gridi ya pafupifupi 80 ndikuwirikiza kawiri kukula kwa gridi pang'onopang'ono. Zotsatira zabwino nthawi zambiri zimapezeka ndi sandpaper ya 1500 kapena 2000-grit. Pa kupukuta kwachitsulo koyenera kwambiri, ganizirani za sandpaper ya grit ya 3000 kapena 5000. Komabe, ndikofunikira kudziwa kuti zotsatira za sandpaper ya grit yapamwamba ndizochepa. Pankhaniyi, tikukulangizani kugwiritsa ntchito phala lopukuta ndi nsalu yoyera, pepala kapena gudumu la ubweya kuti mupeze zotsatira zabwino. Kapenanso, kupukuta kwa mankhwala kungagwiritsidwe ntchito kuti kukhale kofanana ndi galasi. Komabe, ndikofunikira kusamala chifukwa mankhwala otere sangakhale oyenera thanzi lanu.
Zinthu zapulasitiki, ulusi wa kaboni, fiberglass ndi miyala nthawi zambiri zimakhala ndi utoto wofiirira pamwamba pake. Zosankha za sandpaper pazinthu izi ndizochepa, nthawi zambiri zimakhala kuyambira 800 mpaka 2000 grit. Kuti mupeze ukonde wapamwamba, tikulimbikitsidwa kugwiritsa ntchito phala lopukuta. Mukamagwira ntchito ndi mikwingwirima pazinthu izi, ndikofunikira kuonetsetsa kuti pamwamba pake pakhoza kuchepetsedwa mofanana kuti pagwirizane ndi kukanda komwe kulipo. Ngati izi sizingatheke, tikulimbikitsidwa kupewa kupukuta malo chifukwa izi zingayambitse malo osafanana. Pankhaniyi, kugwiritsa ntchito phala lopukuta pamwamba ponse ndikugwiritsa ntchito gudumu la ubweya kungathandize kuchepetsa zizindikiro zooneka. Kusankha ukonde woyenera wa sandpaper pazinthu zosiyanasiyana ndikofunikira kwambiri kuti mukwaniritse mulingo woyenera wa polish.
Kugwiritsa Ntchito Sandpaper
Mukayamba ntchito yokonza masanjidwe, ndi bwino kuyamba ndi sandpaper yokhala ndi grit yochepa. Izi zimatsimikizira kuti sandpaper siitseka mosavuta, zomwe zimathandiza kuchotsa zinthu moyenera. Pa gawo loyambali, kupukuta kouma kumachitika bwino popanda madzi. Ufa wosonkhanitsidwa uyenera kutsukidwa nthawi yomweyo pambuyo pake. Izi zimatsimikizira malo ogwirira ntchito oyera ndipo zimathandiza kuwunika molondola momwe zizindikiro za sandpaper zilili komanso kulunjika kwake. Ngati zotsatira zomwe mukufuna zakwaniritsidwa, mutha kupita ku mesh yotsatira. Pa gawoli ndikofunikira kusintha njira yopangira, ndikupanga ngodya yayikulu ku chizindikiro chapitacho kuti mupewe malo osafanana. Pamene kuchuluka kwa maukonde kukukwera, ndikofunikira kusintha kupita ku grit yonyowa, pogwiritsa ntchito madzi ngati mafuta. Ndikofunikira kudziwa kuti mukamaliza kupukuta konyowa, sandpaper ndi malo ogwirira ntchito ayenera kutsukidwa bwino kuti achotse tinthu tating'onoting'ono tomwe tingadetse pamwamba. Ngati grit ikadetsa pamwamba, ndi bwino kusintha sandpaper ndi njira ina yokhala ndi grit yapamwamba. Kuphatikiza apo, ndikofunikira kusunga chidebe china cha madzi pa mesh iliyonse kuti muchepetse kuipitsidwa kwa chilengedwe. Pamapeto pa tsiku lililonse, mabaketi ndi zinyalala ziyenera kutayidwa kapena kusungidwa bwino kuti malo ogwirira ntchito akhale oyera.
Mukapaka mchenga ndi grit yokwera kwambiri, monga grit ya 2000 kapena 5000, kuyang'anira momwe pepala la sandpaper lilili kumakhala kofunikira kwambiri. Sandpaper yotsekeka ingapangitse kuti kuyikanso mchenga kusakhale kothandiza ndipo kungayambitse kutentha kwambiri ndi kulumikiza pamalopo. Ngati pepala la sandpaper litatsekeka, liyenera kutsukidwa mosamala ndi madzi kapena mafuta kuti muchotse kutsekeka kulikonse. Ndikofunikira kukumbukira kuti kugwiritsa ntchito pepala la sandpaper lotsekeka kungayambitse zotsatira zoyipa. Kudziwa bwino luso lopaka mchenga kumafuna kudziwa bwino njira zosiyanasiyana kutengera grit ya pepala la sandpaper. Kuyambira ndi grit yochepa kuti muchotse zinthu bwino, kupita patsogolo ku grit yapamwamba kuti mumalize bwino, ndikuyika kuyika konyowa ngati pakufunika ndi gawo lofunikira pakuchita bwino kwa kuyika mchenga. Potsatira njira izi ndikusunga pepala la sandpaper ndi workpiece kukhala loyera, kukwaniritsa mawonekedwe abwino a pamwamba kumakhala cholinga chomwe onse okonda kuyika mchenga amakhala. Kumbukirani kuti kuyika mchenga ndi ndalama mu mtundu wa chinthu chomaliza. Mukayika nthawi yoyenera ndi chisamaliro mu njira yanu yokankhira, mutha kutsegula kuthekera kwenikweni kwa ntchito zanu zogwirira ntchito zamatabwa ndi kumaliza.
Kupanga ndi kugwiritsa ntchito mipiringidzo ya sanding
Chipilala choyeretsera chimapangidwa kuti chigwirizane ndi pamwamba pa ntchito, kuonetsetsa kuti chipale choyeretsera chikhale chofanana. Pa malo akuluakulu osalala, ndikofunikira kugwiritsa ntchito chipilala choyeretsera chokhala ndi malo osalala omwe angalumikizidwe bwino kapena kulumikizidwa ndi sandpaper. Komabe, mukamagwiritsa ntchito malo opindika kapena osakhazikika, chipilala choyeretsera chiyenera kupangidwa ndi chinthu chopindika monga nsungwi kapena siponji. Izi zimathandiza kuti chipale choyeretsera chikhale chosalala m'mbali mwa ma radii ndi mizere, zomwe zimapangitsa kuti zikhale zolondola nthawi zonse. Zinthu zamakampani zomwe zimakwaniritsa zosowa izi zimapezeka mosavuta. Zodziwika kwambiri mwa izi ndi zotsukira misomali, zomwe ndi zabwino kwambiri popatsa misomali yanu mawonekedwe osalala. Kuphatikiza apo, ma emery blocks ndi njira yabwino kwambiri m'malo mwa sandpaper yachikhalidwe, zomwe zimapereka mphamvu yodula komanso kulimba. Zida zamafakitale izi zimapangidwa kuti zizitha kugwiritsidwa ntchito molimbika komanso kupereka zotsatira zabwino kwambiri.
Nthawi zina, ndikofunikira kugwiritsa ntchitomasiponji osambira okhala ndi mbiri, monga zomwe zimagwiritsidwa ntchito podula m'mphepete mwa chikopa ndi kupukuta. Mabuloko awa nthawi zambiri amakhala ndi mipata yooneka ngati U kuti igwirizane ndi mawonekedwe a chogwirira ntchito. Popanga mabuloko otere a mchenga, kusavuta kusintha pepala la sandpaper kuyenera kuganiziridwa.
Kukonza ma block chamfering ndi chinthu china chofunikira chomwe sichiyenera kunyalanyazidwa. Ngakhale mukugwiritsa ntchito, m'mphepete mwa sandpaper mutha kusweka. Kuti sandpaper isalumikizane ndikuwononga ntchito, malo aliwonse osweka ayenera kukonzedwa nthawi yomweyo. Pothetsa mavutowa munthawi yake, umphumphu wa sandpaper umasungidwa, kuonetsetsa kuti nthawi zonse imakhala yosalala komanso yopanda chilema.
