Momwe mungasankhire kuchuluka kwa sandpaper pamagalimoto opera

Mbali yam'mbuyo ya masikono, mapepala kapena mawilo apadera okupera amalembedwa. Zimagwirizana ndi Russian GOSTs 1980 ndi 2005 (chilembo chotchedwa "M" kapena "H") ndi miyezo ya ISO yapadziko lonse lapansi (chilembo "P" mu cholembera).

Madalaivala amene amatumikira galimoto zawo paokha saopa nkomwe kujambula thupi. Njira yovuta, komabe, imafuna chidziwitso chachikulu, mwachitsanzo, ndi nambala ziti za sandpaper zomwe zimafunikira pojambula, kugaya, kupukuta galimoto. Mutuwu ndi wofunika kuufufuza.

Mitundu ya zikopa zopweteka

Sandpaper (sandpaper) ndi chinthu chopera choperekera mawonekedwe ena pamwamba asanapente ndikupangitsa kuti chiwale ndi gloss pambuyo pake. Musanayambe kupeza chiwerengero cha sandpaper chojambula galimoto, muyenera kumvetsetsa mitundu ya abrasive. Kugawanika kumayendera maziko, pomwe abrasive amagwiritsidwa ntchito ndi guluu kapena mastic.

Pali mitundu iyi ya zikopa:

• Mapepala. Iyi ndiye njira yodziwika bwino komanso yotsika mtengo, yomwe imakulolani kugwiritsa ntchito tchipisi tating'ono kwambiri pamapepala.
• Nsalu zochokera. Sandpaper iyi imakhala yotanuka komanso yosavala, zomwe zimakhudza mtengo.
• Kuphatikiza. Kuphatikizika kwa njira ziwiri zam'mbuyomo kwatengera zinthu zabwino kwambiri: kusinthasintha - kuchokera pansalu, kuthekera kogwiritsa ntchito bwino abrasive - kuchokera pamapepala.

Abrasive nsalu pa nsalu maziko

Sandpaper amapangidwa mu mapepala kapena masikono. Kusankha nambala yoyenera ya sandpaper yopera galimoto, choyamba muyenera kutchula lingaliro la "tirigu".

Grit Marking

"Mbewu" - abrasive ufa - ali ndi makhalidwe osiyanasiyana:

• kukula
• zinthu zopangidwa;
• kachulukidwe ka ntchito pa inchi lalikulu.

Magawo awa amakuthandizani kusankha nambala yofunikira ya sandpaper yopukutira galimoto.

Grit imayesedwa mu ma micrometer (µm). Kusintha kwa zinthu za emery kumayenderana ndi kukula kwa tinthu ta abrasive:

• Chachikulu. Matchulidwe a manambala - kuyambira 12 mpaka 80. Mapepala amagwiritsidwa ntchito pokonzekera mwakhama, kukonza koyambirira kwa malo okonzedwa. Mbewu zazikulu zimatulutsa tchipisi, ma welds.
• Avereji. Wosankhidwa ndi zizindikiro kuyambira 80 mpaka 160, amagwiritsidwa ntchito pokonza bwino ziwalo za thupi, kukonzekera komaliza kwa putty. Kuchokera ku zizindikiro za granularity, chiwerengero cha sandpaper chojambula galimoto chimasankhidwa.
• Wamng'ono. Kuchuluka kwakukulu kwa ufa wonyezimira kumayikidwa pa inchi imodzi, kuyambira kukula kwa 160 mpaka 1400. Mkati mwa malire awa, pali sandpaper yochuluka ya kupukuta galimoto, yomwe idzafunika pomaliza kujambula.

Chithunzichi chikuwonetsa tebulo la mchenga wa mchenga wa zipangizo zosiyanasiyana.

Mchenga grit tebulo zipangizo zosiyanasiyana

Gome likuwonetsa kuti ziwerengero za sandpaper zovula pambuyo poyika galimoto zili pakati pa 180 mpaka 240.

Mbali yam'mbuyo ya masikono, mapepala kapena mawilo apadera okupera amalembedwa.

Zolemba za sandpaper

Zimagwirizana ndi Russian GOSTs 1980 ndi 2005 (chilembo chotchedwa "M" kapena "H") ndi miyezo ya ISO yapadziko lonse lapansi (chilembo "P" mu cholembera).

Abrasives ntchito

Monga nyenyeswa (ufa) pamunsi, opanga amagwiritsa ntchito miyala, mchenga, miyala ya chipolopolo ndi zipangizo za polima.

Ma abrasives otchuka:

• Garnet. Chiyambi chachilengedwe chimapereka kufewa komanso kukhazikika kwa emery, yomwe nthawi zambiri imagwiritsidwa ntchito pokonza matabwa.
• Silicon carbide. Ufa wamba wapadziko lonse wogwirira ntchito ndi utoto, malo achitsulo.
• Ceramic crumb. Chinthu cholimba kwambiri chimafunika kupanga mapangidwe.
• Zircon corundum. Abrasive yosamva nthawi zambiri imapangidwa ngati lamba wopukutira.
• Alumina. Kukhazikika kwa abrasive kumalola kuti agwiritsidwe ntchito pakunola m'mphepete.

Silicon Carbide Sandpaper

Posankha manambala a sandpaper opaka magalimoto, samalani ndi silicon carbide abrasive.

Momwe mungapangire sandpaper moyenera

Ukadaulo ndi wosavuta. Chinthu chachikulu ndicho kulondola ndi kuleza mtima. Kuti mupange mchenga, muyenera kutenga mapepala a sandpaper osiyanasiyana pojambula galimoto - kuyambira chaching'ono mpaka chachikulu kwambiri.

Zotsatira za ndondomeko

Gwirani ntchito m'bokosi laukhondo, lowuma, lowala bwino. Chitani chonyowa kuyeretsa, kuphimba pansi ndi makoma ndi pulasitiki Manga.

Konzani maovololo, tetezani ziwalo zopumira ndi chopumira, maso ndi magalasi. Sonkhanitsani nyenyeswa zomwe zinapangidwa panthawi ya mchenga ndi chotsukira.

Ntchito yokonzekera

Chotsatira chomaliza cha kudetsa mwachindunji chimadalira gawo lokonzekera:

1. Sambani galimoto yanu pamalo ochapira magalimoto kaye.
2. Mu garaja, chotsani mapulasitiki onse, mbali za chrome zomwe sizikugwirizana ndi kujambula.
3. Sambani galimoto kachiwiri ndi shampu, pukutani youma, degrease ndi mzimu woyera.
4. Yang'anani thupi, yesani kukula kwa ntchito. N’zotheka kuti si malo onse amene adzayeretsedwe, kupakidwa utoto ndi kuwapaka mchenga.
5. Bweretsani malo omwe amafunikira, wongolerani.

Ntchito yokonzekera

Kenako yeretsaninso chipindacho.

Makhalidwe a pamanja akupera

Kuti muwongolere ntchitoyi, konzani mchenga pasadakhale - chipika chokhala ndi sandpaper. Mutha kugula chipangizo kapena kudzipangira nokha kuchokera kuzinthu zosinthidwa: mtengo, siponji yolimba.

Gawo loyamba la kuvula thupi la amakaniko agalimoto ndi ojambula limatchedwa matting. Ndikosavuta kupukuta m'malo akulu pogwiritsa ntchito chopukusira, koma pomwe chida sichingakwawa, ndibwino kuchipaka pamanja. Nambala ya sandpaper yokweza galimoto ndi P220-240.

Pambuyo pa njirayi, zipsera, zokwawa, ndi zolakwika zina zimawonekera bwino. Thamangani khungu pansi pa nambala P120: idzatulutsanso zokopa, m'mphepete mwa utoto, kuyeretsa dzimbiri.

Sanding mkono

Cholinga cha ndondomeko pa siteji iyi si yosalala pamwamba. Pakumatira bwino kwa putty ndi chitsulo chamthupi, zokopa zazing'ono yunifolomu ziyenera kukhalabe pamapeto pake.

Musaiwale kupukuta zinyalala. Pamene pamwamba akukonzekera, putty izo, mulole izo ziume. Sankhani nambala yoyenera ya sandpaper yopera mutatha kuyika galimoto, dutsani mapanelo onse.

Mmodzi wosanjikiza woyamba sikokwanira, kotero kuphimba thupi ndi yachiwiri, ngati n'koyenera, ndi wachitatu wosanjikiza, nthawi iliyonse mchenga kukonza malo.

Momwe mungagaye putty pagalimoto ndi chopukusira

Zotsatira zabwino kwambiri zidzakwaniritsidwa ndi eccentric orbital sander. Chida chamagetsi ndichosavuta kugwiritsa ntchito: mumangofunika kumangiriza mawilo apadera akupera ndi mabowo okwera pamakina. Kenako yendetsani pamwamba munjira zosankhidwa mwachisawawa.

Zida zimaperekedwa ndi chosonkhanitsa fumbi chomwe chimayamwa zotsalira za abrasive. Ndikofunika kusankha nambala yoyenera ya sandpaper ndi kukula kwa tirigu pogaya nthaka pagalimoto, ndipo liwiro ndi khalidwe lidzaperekedwa ndi chipangizocho.

Sanding ndi chopukusira

Kwa madera akuluakulu komanso osalala, sander ya lamba idzachita. Ikani sandpaper kwa iyo ngati chinsalu. Kenako, yatsani chipangizocho ndipo, mutagwira chogwiriracho, yendetsani njira yoyenera. Ndikoyenera kuganizira mphamvu ya chida: makina amatha kupukuta chitsulo chachikulu.

Malangizo ochepa owonjezera

Mchenga wapamwamba kwambiri mwina ndi nthawi yokonzekera isanayambe kudetsa. Apa zinachitikira ndi mwachilengedwe amatenga mbali yaikulu.

Werenganinso: Momwe mungachotsere bowa m'thupi la galimoto ya VAZ 2108-2115 ndi manja anu

Malangizo ochokera kwa amakanika odziwa ntchito zamagalimoto:

• Ngati thupi lonse siliyenera kupangidwa ndi mchenga, phimbani pafupi ndi malo okonzerako ndi masking tepi.
• Mukakonza malo obwezeretsa, musaope kutenga malo okulirapo kuposa momwe mulili vutolo.
• Musanayambe mchenga, chitirani putty ndi wopanga wakuda: ziwonetsa komwe mungawonjezere ma putty.
• Nthawi zonse sungani ndikugwira ntchito ndi zikopa zopyapyala, zapakati komanso zosalala.
• Ndikofunikira pogaya zitsulo ndi putty molimbika mosiyanasiyana: wosanjikiza woyambira amakhala wofewa nthawi zonse ndipo amangochotsedwa pachangu kwambiri.
• Yambani ndi sandpaper coarse-grained, kenaka muwonjezere kuchuluka kwa sandpaper yopukuta galimoto ndi mayunitsi 80-100.

Pa ntchito, chotsani fumbi, kuchita chonyowa kuyeretsa.
