Lokukhuhla: enyama kunye nokusetyenziswa

Xa uthetha lokukhuhla ezidla ngokubizwa ngokuba "sandpaper" okanye "isikhumba."

Le ibandakanya iphepha okanye ilaphu isiseko isale umaleko wezinto esirhabaxa.

Kwimveliso ezinxulumene kunye nokuqwalaselwa iinkuni, iplastiki, intsimbi, neglasi ngaphandle nazhdachki. Kuyinto buyafuneka xa kususwa ipeyinti ubudala, akukho enye xa ufuna ukulungiselela ebusweni for primer kunye nepeyinti, njl

The Chinese yamandulo ngenkulungwane ye-13 kunye ngoncedo iglu ngokusekelwe wesitatshi uwuyeke iimbewu ngesikhumba yezityalo, isanti womsizi kunye lukhule.

Kwase kwephepha sanding uthathwa i "iphepha iglasi" ngenxa esetyenziselwa imveliso amasuntswana yayo iglasi minute.

Ngowe-1834, i-Injineli waseMelika A. Fischer Jr. kuqala enelungelo imveliso elilukhuni ngelaphu, iinkozo esirhabaxa eye Karbid Kremniya kunye alumina.

Kufuneka wazi ukuba ingqolowa sandpaper kwaye enye neempawu zalo eziphambili.

Ngokuqhelekileyo, iphepha yahlulwe ngamaqela: erhabaxa, aphakathi kunye nephepha ingqolowa entle.

ubukhulu Grain umisela uhlobo lomsebenzi othi sandpaper. Kwakhona zokuphawula kuya kukunceda ukuba ukhethe.

Elilukhuni enze umsebenzi unyango nobushushu kumphezulu zonke iintlobo putty.

Kuba ezahlukeneyo iintlobo zomsebenzi kusetyenziswa ukwahlula phakathi okuziinkozo kunye isiseko sandpaper. Ukumakishwa kwi iphepha elithile.

uhlalutye lokukhuhla

N - kophawu imveliso yasekhaya (ubudala).

P - kophawu imveliso kumazwe angaphandle kunye nokufaka ezintsha iimveliso zasekhaya.

Abavelisi ezivelisa impahla kwamanye amazwe, sebenzisa isiqu yomhlaba eyodwa umgangatho ubukhulu okuziinkozo.

Kwamanye amazwe angamalungu Union iwa sandpaper, ukumakisha imveliso ogqityiweyo imveliso elilukhuni zenziwa ngokwe GOST (endala).

Le nto inye eyenzeka e Canada, China, i-US kunye Japan, apho kurhwebo lwasekhaya ixhamla neempawu zaso.

Standard European (GOST omtsha) kuthetha ukwanda amaxabiso ngokunciphisa ubungakanani okuziinkozo. Ngokupheleleyo ezahlukeneyo kula mazwe ephawulwe sandpaper.

Standard, ngokomzekelo, yenziwe ukwenzela ukuba amaxabiso a, phezu koko, wehlise kunye nokunciphisa ubungakanani okuziinkozo.

Ezi mahluko ayikwazi ngoyaba xa uthenga iimveliso esirhabaxa kummandla elalisakuba yiSoviet Union, njengoko Lo mahluko kungabangela iba kukufunyanwa kwempahla engalunganga.

Kufuneka kuqatshelwe ukuba iphepha amazwe amaninzi kuthengiswa iimveliso, kwaye basekhaya - in rolls, yaye bathengisa imitha yayo.

Ukuba iphepha isetyenziswa kubomi bemihla ngemihla, akukho mfuneko ukukhumbula kumakishwa. Kuyimfuneko kuphela ukwazi ukuba ngokokubhalishwa omdala kunye unobumba H emva inombolo, kwaye omtsha unobumba P phambi kokuba inani.

Kwicala ngasemva kwiphepha, kukho ezinye abizwa. Banako ukufumana ingcaciso engaphezulu malunga sandpaper: lisekelwe, ubuchwepheshe yemveliso, uhlobo lwezinto okuziinkozo esirhabaxa, uhlobo iglu, njl ...

Ke kaloku, ukuba uyazi ukuba yintoni na sandpaper. Kukhunjulwe? Ngayo, wena, nawe, yakuqonda. Kuhleli ukunqwenelela wonke umsebenzi emnandi kunye nemveliso.
