Kupukuta matombo inzira inongwarira inoda kusarudzwa kwakanyatsonaka kwesandpaper yakakodzera kana abrasive pad. Saizi yemagrit inokanganisa zvakananga kupedzisa kwekumusoro kwedombo, saka saizi yemagrit yakakodzera inofanira kusarudzwa zvichienderana nekuoma kwedombo uye mhedzisiro yekupukuta inodiwa. Chinyorwa chino chichaongorora hukama huripo pakati pehukuru hwesandpaper grit nemigumisiro yekupukuta, uye kupa gwara rekusarudza saizi yemagrit yakakodzera yemhando dzakasiyana dzematombo.
Hukama Huri Pakati Pekukura Kwemagaro Ejecha Nemhedzisiro Yekupukuta
Saizi yejecha resandpaper inoreva huwandu hwezvidimbu zvinogumbura pa sikweya yesandpaper. Kuyerwa uku kunoratidza kuomarara kana kupfava kwesandpaper:
Matombo mashoma (80-120): Matombo akakora anoshandiswa pakukwesha dombo pakutanga uye kubvisa mavanga akadzika kana mavanga pamusoro pedombo. Matombo aya anoita mavanga makuru uye akakodzera kukwesha dombo pakutanga.
Tsvina yakawanda (600-1000 grit zvichikwira): Tsvina yakawanda inoita mavanga madiki, zvichiita kuti nzvimbo yacho ive yakapfava uye yakashongedzwa. Sandpaper ine grit yakawanda inoshandiswa padanho rekupedzisira rekukwesha, apo chinangwa chiri chekuti nzvimbo yacho ive yakatsetseka uye inopenya.
Chinhu chikuru chekukwesha zvinobudirira ndechekuwedzera zvishoma nezvishoma saizi yegrit panguva yekukwesha. Kutanga negrit shoma kunogona kubvisa kusakwana, nepo kuchinja zvishoma nezvishoma kuenda kugrit yakakura kunogona kunatsa pamusoro uye kuwedzera kupenya.
Sarudza Grit Yakakodzera Zvichienderana Nekuoma Kwedombo
Kuoma kwedombo kunoita basa rakakosha pakusarudza saizi yakakodzera yekukwesha grit:
Matombo akapfava (semuenzaniso sipo, limestone):
Kukwesha Kwemasandpaper Kunokurudzirwa: Pakukwesha kwekutanga, zvinokurudzirwa kushandisa sandpaper ine grit shoma, senge grit 80-120. Matombo akapfava ari nyore kukuya nekukwesha, saka sandpaper ine grit yakakura inogona kushandiswa kuwana mhedzisiro inogutsa.
Maitiro: Mushure mekubvisa mavanga akadzika, shandisa zvishoma nezvishoma mavanga akakwirira (kusvika pamavanga 600) kuti pave nepamusoro pakanaka.
Dombo rakaoma riri pakati nepakati (semuenzaniso marble, travertine):
Kukwesha Kwemasandpaper Kunokurudzirwa: Pakukwesha kwekutanga, tinokurudzira kushandisa sandpaper inosvika 120-220 grit. Izvi zvichabatsira kubvisa kusakwana kwepamusoro ukuwo zvichinyatsoita kuti dombo risakuvadzwe.
Maitiro: Padanho rekupedzisira rekupukuta, shandisa magrits akapfava (anosvika grits 1000) kuti uwane kupenya kwakanyanya.
Dombo rakaoma (semuenzaniso granite, quartz):
Grit Inokurudzirwa: Kana matombo akaoma, tanga negrit yakakura, senge grit 220-400, kudzivirira kupera zvakanyanya kwejecha uye kupukuta pamusoro payo zvinobudirira.
Maitiro: Kuchinja kuita grit yakapfava (kusvika kugrit 3000 kana kupfuura) kuti ipedzwe pakupedzisira kuti ipedzwe segirazi.
Nzvimbo yeSandpaper Grit Inokurudzirwa
Kukwesha kwekutanga:
Kune mhando zhinji dzematombo, 80-120 grit sandpaper ndiyo yakakodzera pakukwesha kwekutanga. Grit iyi inobvisa zvinobudirira nzvimbo dzakaomarara, mavanga, uye zvikanganiso zvinoonekwa, ichiisa hwaro hwakasimba hwekukwesha kwakanaka kunotevera. Grit yakakura inobatsira kugadzira dombo nekukurumidza, ichirigadzirira kukwesha nekukwesha kwakanyanya.
Kupukuta kwakanaka:
Kana pamusoro pedombo pakatsetseka, unofanira kuwedzera zvishoma nezvishoma grit yesandpaper kuti uikweshe zvakanaka. Kazhinji, zvinokurudzirwa kushandisa grit sandpaper ine 600-1000 kuti uwane grit yakanaka. Grit iyi inobatsira kunatsa pamusoro uye kuwedzera kupenya kwayo.
Kana zvichidikanwa kuti pave nekupedzwa kwakanaka, shandisa sandpaper ine grit yakakwira, senge grit 1500 kana kupfuura. Aya ma sandpaper ane grit yakapetwa zvakanaka akanakira kugadzira finish inopenya zvakanyanya, kunyanya pakushandisa zvishongo zvepamusoro.
Zvinyorwa paKupukuta
Pamusoro pekusarudza sandpaper yakakodzera, matanho akati wandei anofanira kutorwa kuti ive nechokwadi chekuti kukwesha kunobudirira:
Chengeta nzvimbo yakachena: Usati watanga kupolisha, iva nechokwadi chekuti sandpaper nematombo zvakachena. Kusachena kunogona kukonzera kukwenya uye kukanganisa mhedzisiro yekupedzisira.
Shandisa mvura kana mvura yekupukuta: Kuwedzera mvura kana mvura yekupukuta pakupukuta kunobatsira kuderedza kupisa pakati pesandpaper nedombo. Izvi hazvingodziviriri dombo kupisa zvakanyanya, asi zvinowedzerawo kupukuta nekurizora.
Wedzera zvishoma nezvishoma saizi yejecha resandpaper: Munguva yekupukuta, zvakakosha kuwedzera zvishoma nezvishoma saizi yejecha resandpaper. Kushaikwa kwejecha kuchaita kuti pave nekukwesha kusina kuenzana uye zvingada basa rakawanda kuti rigadziriswe. Kuchinja kwakanaka kubva pajecha rakaoma kuenda kune rakatsetseka kunoita kuti pave nekukwesha kwakaenzana.
Tarisa kumanikidzwa: Paunenge uchipukuta, shandisa kumanikidzwa kwakasimba uye kuri pakati nepakati. Kumanikidzwa kwakawanda kunokonzera kupera kusina kuenzana kwepepa rejecha uye kunogona kukuvadza pamusoro pedombo.
Mhedziso
Kusarudza chakakodzerapepa resandpaperSaizi yemagrit idanho rakakosha mukukwesha matombo. Kunzwisisa mhando dzemagrit dzinokurudzirwa pakukwesha kwekutanga nekwekupedzisira, uye kutora matanho anodiwa ekudzivirira, kuchaita kuti pave nemigumisiro yakanaka. Kunyangwe uri kushanda nezvinhu zvakapfava kana zvakaoma, kusarudza saizi yakakodzera yemagrit zvichienderana nekuoma kwedombo uye kupedzisa kwaunoda kuchaita kuti pave nepamusoro pakanaka. Nekutarisisa zvakadzama uye nzira chaiyo, unogona kuwedzera runako rwechisikigo rwedombo uye kuwana polish yemhando yepamusoro.
