Isikhokelo seGrit yeSandpaper: Ngaba iiGrit ezincinci ziqinile?

Imigaqo esisiseko yeSandpaper

Iphepha lokugquma lenzelwe ukugudisa iindawo ngokususa izinto ngokusebenzisa ukurhawuzelelwa. Ukusebenza kakuhle kwephepha lokugquma kuxhomekeke kubukhulu kunye nokuma kweengqayi ezirhabaxa ezinamathele kumphezulu wazo. I-grit ibhekisa kubukhulu bezi ngqayi, ezilinganiswa kusetyenziswa isikali esiqhelekileyo.
Umqolo: Yimpahla engasemva ebamba amasuntswana arhabaxa endaweni yawo. Ngokuxhomekeke kwindlela ekucetywayo ukusetyenziswa ngayo, umqolo ungenziwa ngezinto ezahlukeneyo kuquka iphepha, ilaphu, okanye ifilimu.
I-Abrasive: Iisuntswana ezenza ukugaya. Izinto eziqhelekileyo ziquka i-aluminium oxide, i-silicon carbide, kunye ne-diamond.

Ubungakanani beSandpaper kunye noHlobo loBurhabaxa

I-grit yephepha lesanti idla ngokubonakaliswa ngamanani e-mesh, akwabizwa ngokuba ngama-grades ephepha lesanti. Eli nani libonisa inani lemingxuma nge-intshi yesikwere kwisikrini esisetyenziselwa ukwahlula i-abrasive. I-grit ihlelwe ngolu hlobo lulandelayo:

1. Iphepha lokusandpaper elirhabaxa (20-60):

Iimpawu: Iphepha lesandpaper elirhabaxa linamaqhekeza amakhulu arhabaxa, afanelekileyo ukususa izinto ezinzima. Liyasebenza ekubumbeni umthi, ekususeni ipeyinti, okanye ekugudiseni iindawo ezirhabaxa.
Ukusetyenziswa: Ifanelekile ekutshixeni iindawo ezirhabaxa, ekugqibeni ukuhluba, nasekubumbeni izinto.

2. Iphepha lesandpaper eliphakathi le-grit (80-120):

Iimpawu: Iphepha lesandpaper eliphakathi lilungelelanisa ukususwa kwezinto kunye nokugudisa umphezulu. Linamasuntswana amancinci kunelo lesandpaper elirhabaxa, kodwa lisasebenza kwimisebenzi yokugudisa ngokubanzi.
Ukusetyenziswa: Ilungele ukugquma phakathi kweengqimba zepeyinti okanye ukugqiba, ukuthambisa imiphetho erhabaxa nokulungiselela umphezulu ukuba ugqume kakuhle.

3. Iphepha lokusila elicolekileyo (150-180):

Iimpawu: Iphepha lesanti elincinci linamasuntswana amancinci arhabaxa kwaye lifanelekile ukwenza umphezulu ube bushelelezi. Lisusa izinto ezincinci kunephepha lesanti eliphakathi, kodwa lenza umphezulu ube mhle ngakumbi.
Ukusetyenziswa: Ukutshiza kokugqibela ngaphambi kokupeyinta, ukupolisha imiphezulu kunye nokususa amabala.

4. Umgubo ocolekileyo kakhulu (240-400):

Iimpawu: Iphepha lesanti elicolekileyo kakhulu lokupolisha nokugqibezela. Linamasuntswana amancinci kakhulu enza umphezulu ogudileyo nocociweyo.

Ukusetyenziswa: Ifanelekile ukugquma phakathi kweengqimba zevarnish okanye ipeyinti, ukugqiba umphezulu womthi kunye nokulungiselela isinyithi sokupolisha.

5. Umgubo ocolekileyo kakhulu (ongama-400 nangaphezulu):

Iimpawu: Iphepha lesanti elincinci kakhulu kwiindawo ezigudileyo kakhulu. Lisetyenziswa rhoqo kwiindawo zokusebenza ngeemoto kunye nezokhuni apho kufuneka umphezulu ogqibeleleyo.
Ukusetyenziswa: Ilungele ukupholisha kokugqibela, ukugquma kunye nokulungiselela iindawo ezikhazimlayo.

Yintoni umahluko kwiSandpaper Grit?

1. Unyango olurhabaxa lomphezulu (umhlaba oqingqiweyo 20-60)

Iphepha lokusila elirhabaxa lidla ngokusetyenziswa xa kusetyenzwa ngezinto ezirhabaxa ezifana nomthi, isinyithi, okanye ikhonkrithi. Ubungakanani bamasuntswana angama-20 ukuya kuma-60 bufanelekile.

Isicelo:

Susa ii-burrs kunye ne-rust: Iphepha lesanti elirhabaxa lisebenza kakuhle ekususeni ii-burrs, i-rust kunye nezinye iziphene zomphezulu. Lisusa izinto ngokukhawuleza kwaye lifanelekile kwimisebenzi yokuqala yokusila.
Izinto zokubumba: Olu bungakanani bomhlaba lukwaluncedo ekubumbeni izinto, nto leyo ekuvumela ukuba ususe izinto ezininzi ngexesha elifutshane.

Umgubo ocetyiswayo:

I-sandpaper grit 20-40: Ilungele ukususa nokubumba izinto ezinzima.
I-grit yesanti 60: Ifanelekile ukuthambisa iindawo ezirhabaxa ngaphambi kokusebenzisa ii-grit ezincinci.

2. Unyango oluqhelekileyo lomphezulu (iinkozo 80-120)

Xa ugquma ifanitshala, iingcango kunye neefestile, kucetyiswa ukusebenzisa iphepha lesanti eliphakathi (80-120). Obu bungakanani bamasuntswana bubonelela ngolungelelwano phakathi kokususwa kwezinto kunye nokuguda komphezulu.

Isicelo:

Ukusanta ifenitshala: Ilungele ukulungiselela umphezulu womthi ukuze ugqitywe kuba inceda ukususa iziphene ngaphandle kokususa izinto ezininzi.
Iingcango neefestile: Ncamathisela kakuhle iindawo ezipeyintiweyo okanye ezinemibala ukuze zigqibelele ngokulinganayo.

Umgubo ocetyiswayo:

I-sandpaper grit 80: Ukucoca imiphezulu kuqala kufuna ukugqitywa okuphakathi.
I-sandpaper grit 120: Ifanelekile ukucocwa kokugqibela ngaphambi kokupeyinta okanye ukugqunywa okucacileyo.

3. Ukupolisha ngesinyithi (iinkozo 150-180)

Xa kupolisha imiphezulu yesinyithi efana neempompo, iziphatho, kunye nezinye izinto ezisetyenziswayo, iphepha elincinci lesandpaper eliphakathi kwe-150 ukuya kwi-180 grit lidla ngokusetyenziswa.

Isicelo:

Ipolishi eneenkcukacha: Olu bungakanani begrit lusebenza kakuhle ekufumaneni ipolishi egudileyo kwiindawo zesinyithi, ukususa imikrwelo emincinci kunye namabala.
Ukulungiswa kwengubo: Ikwalungele nokulungiselela imiphezulu yesinyithi yokupeyinta okanye yokugquma, ukuqinisekisa ukuba inamathela ngcono.

Umgubo ocetyiswayo:

I-sandpaper grit 150: Ilungele ukupholisha nokuthambisa imiphezulu yesinyithi kwasekuqaleni.
I-sandpaper grit 180: Inika umphezulu ogqibeleleyo, ofanelekileyo ekufumaneni i-polish yomgangatho ophezulu.

4. Ukupholisha umphezulu ngokuchanekileyo (iinkozo 240-2000)

Ukuze upholise umphezulu wezinto ezifana neglasi neplastiki, sebenzisa iphepha lesanti elicolekileyo kakhulu eline-grit engama-240 ukuya kuma-2000. Obu bukhulu bamasuntswana bubalulekile ukuze ufumane ukukhanya okuphezulu kunye nokugqitywa komphezulu okuthambileyo.

Isicelo:

Ukupholisha ngeglasi nangeplastiki: Iphepha lesanti elincinci kakhulu lilungele ukupholisha imiphezulu yeglasi ukuqinisekisa ukucaca nokukhazimla. Lingasetyenziswa nakwiinxalenye zeplastiki ukuze kubekho umphezulu ogudileyo nocwebezelayo.
Ukugqitywa kokugqibela: Olu hlobo lomgubo ludla ngokusetyenziswa kwizigaba zokugqibela zokulungiswa komphezulu, nto leyo efuna ukugqitywa okugqibeleleyo.

Umgubo ocetyiswayo:

I-sandpaper grit 240-400: ifanelekile ekupolisheni okucolekileyo kwangaphambili.
I-sandpaper grit 600-2000: Yenzelwe ukupholisha kakuhle kakhulu ukuze kufumaneke umgangatho ophezulu wokugudiswa nokukhazimla.

Ukuququmbela

Ngamafutshane, ubuchule beiphepha lokusantiihambelana ngokuphambeneyo nobunzima bayo: okukhona i-grit incinci, kokukhona i-sandpaper ikhula ibe nkulu, ngelixa i-grit inkulu, kokukhona i-sandpaper ilula. Ukuqonda iimpawu ze-grits ezahlukeneyo kubalulekile ekukhetheni i-sandpaper efanelekileyo kwiprojekthi yakho. Ngokukhetha i-grit efanelekileyo, ungafikelela kwisiphumo esifunekayo kwaye uqinisekise iziphumo ezilungileyo kwimisebenzi yokusila nokupolisha. Nokuba usebenza ngamatye, iiseramikhi, okanye ezinye izinto, ukwazi ukusebenzisa i-sandpaper ngokufanelekileyo kuya kuphucula umgangatho womsebenzi wakho.
