chuma ndi chiyani?

Kusintha abrasive pepala kapena maziko nsalu, pamwamba ntchito zomwe TACHIMATA granular ufa wosanjikiza, - ndi sandpaper. Mitundu ya chuma kupeza ntchito pa processing wa matabwa, zitsulo, pulasitiki, galasi, zipangizo wamba.

History chitukuko

Malinga ndi malipoti zalembedwa, nthawi yoyamba pa sandpaper anamugwiritsa ntchito ambuye Chinese m'zaka XIII. Okhakhala anachita ndi kukonza osakaniza mchenga, wosweka seashells ndi mbewu zomera ntchito wowuma zomatira pa chikopa akhakula maziko. Nthawi zambiri, monga abrasive kwa Machining akhakula ntchito particles chabwino cha magalasi osweka.

Woyamba siriyo yopanga sandpaper kukubereka mu 1833, pamene setifiketi kwa kupanga zatsopano wakhala chikalata kuti wazamalonda American Isaac Fischer m'tauni ya Springfield (State wa Vermont).

Kenako, zotsatira ntchito linapereka maziko Kutulukira madzi sandpaper. Mtundu wa sandpaper anagwira kusintha ang'onoang'ono makampani magalimoto. Makamaka ndi izo zimatsegula kuthekera kwa kuwamaliza mofulumira ndi mosamala mbali.

Features ya ntchito

Mankhwalawa kali ndi nsalu crocus ayenera kutsata malamulo ena. Pa ntchito pa malangizo vuto loyamba zomveka amachita ntchito ya sandpaper kwambiri coarse. Major tirigu yosayenera matabwa wosemera processing, kuchotsa chakale utoto, dzimbiri wosanjikiza.

Chabwino sandpaper ntchito pa siteji mapeto umapezeka, kupukuta zitsulo, penti pamalo. Kukonza pulasitiki abwino njira amachita khungu ndi graininess kochepa.

Masiku ano, ambuye likupezeka madzi sandpaper, ntchito zimene amapewa fumbi kuchuluka mu njira ya ntchito. Chifukwa umapezeka yonyowa wa pamalo azisonyeza kukhala yosalala, wokongola kwambiri kapangidwe.

makhalidwe a

Mwa liwulo Magwiridwe crocus nsalu anali olekanitsidwa motere:

• Zofunika m'munsi.
• Indicators tirigu.
• Khalidwe zapansi mafakitale ogwiritsa ntchito monga mbewu.

Sandpaper - mitundu

Okhakhala anapatukana mu mitundu munthu makamaka monga m'munsi kumene ndi abrasive umagwiritsidwa ntchito. The mankhwala ambiri mokomera pepala ofotokoza. njira makamaka wotchipa ndi zaukhondo kukana kuvala. zigawo zikuluzikulu kwambiri dongosolo amasiyana makhalidwe kufumbwa komanso kupereka mwayi kwa ntchito mbewu zing'onozing'ono.

Sandpaper nsalu ali mkulu avale kukana. Pogwiritsa ntchito resins apadera, n'zotheka kupereka chinyezi kugonjetsedwa khalidwe. Komanso, minofu gawo lapansi amapanga zinthu kwambiri kusintha.

Mu kuganizira zinthu sandpaper (mitundu ya zipangizo), osanenapo mankhwala pamodzi. Chotero abrasives TACHIMATA amadziŵika ubwino yeniyeni onse a embodiments pamwambapa. Choncho mtengo wa mankhwala amenewa. Ponena za ntchito, pamodzi abrasives amatha kupirira mkulu mawotchi katundu.

graininess

Malinga ndi akalozera graininess akutsatira options sandpaper:

1. Coarse - umagwiritsidwa ntchito m'munsi, zida ndi zipangizo wosemera, kuchotsa Mankhwala oipitsa, utoto, zotsatira dzimbiri. Akupera ntchito abrasives mu gulu ili pa pamalo a Masamba akuya kwambiri, textured zochepa chabe.
2. A sing'anga - ntchito zipangizo ndi kuchita processing wapakatikati. Akupera pamalo ovomerezeka ntchito pepala amenewa, monga matabwa, timatha inu agwirizane ndi flatten ndege.
3. The bwino grained - akutumikira njira yabwino kukonzekera zipangizo kwa processing wa formulations utoto. khungu amenewa mosavuta kuthetsa zimakhalapo zazing'ono kuchokera pamalo ndi zilema zazing'ono.

mtundu wa abrasive

Monga abrasives mu kupanga sandpaper ntchito ndizosowa amenewa:

1. Garnet - ndi nkhani ya chiyambi zachilengedwe, zomwe amachita ngati njira mulingo woyenera kutsirizitsa kwa nkhuni achilengedwe.
2. Karbid Kremniya - kwambiri mkulu-abrasive. Zikopa ndi mafunsidwe a mbewu zimenezi ndizo chida chofunika ntchito zitsulo, pulasitiki. Carbide grit oyenera kukonza pamalo utoto, kupukuta galasi.
3. Zoumbaumba - khungu loterolo ❖ kuyanika ntchito mu sitepe ya kupanga m'munsi kapangidwe nkhuni, komanso kuwonongedwa kwa zopindika chionetsedwe. M'mawu ena, ichi pepala sandpaper sander ntchito pamene kugwira ntchito akhakula. Mu kwambiri pa zinthu kukumana dongosolo akhoza looped mu mawonekedwe a sanding malamba kuti ntchito pamalo Machining.
4. Aluminiyamu - losiyana dongosolo makamaka wosalimba. Polenga mikangano ndi pamalo a mitundu abrasive latsopano lakuthwa m'mphepete. Choncho khungu la ngati pulani ndi durability chidwi. Zimenezi zikugwira sandpaper makamaka matabwa ndi makampani kupala matabwa.

Kuti mudziwe zambiri,

Kuwonjezera mbewu, pa ma CD a sandpaper akhoza anasonyeza mwa mfundo izi zowonjezera:

• Ntchito - zochepetsera zitsulo pamalo kapena otsika kuuma zipangizo ovomerezeka.
• magawo tsamba - m'litali ndi m'lifupi.
• The zikuchokera kwa abrasive ndi nusu ake.
• Khalidwe-zomatira ntchito kukonza abrasive (synthetics, Amber varnish, formaldehyde utomoni, pamodzi mitsempha).
• Mlingo wa durability la mankhwala.

pomaliza

Poyerekeza ndi zipangizo zina akupera, mu maburashi makamaka zitsulo, sandpaper mwala woperera mutuluka kwenikweni wotchipa, kupezeka kwa zithunzi linafalitsidwa kwambiri ogula omvera. Today abrasive nsalu opangidwa mu mawonekedwe a n'kupanga, mabwalo, mapepala, matepi. Zonse zimenezi kumathandiza kuti ntchito zake zimangokhala malo ambiri osiyanasiyana kuchita ntchito ya ntchito ndi dzanja ndi ntchito zida zogwiritsa ntchito magetsi.
