Indlela yokukhetha inombolo ye-sandpaper yokugaya izimoto

Uhlangothi olungemuva lwemiqulu, amashidi noma amasondo okugaya akhethekile amakiwe. Ihambisana ne-Russian GOSTs ka-1980 no-2005 (igama lezinhlamvu "M" noma "H") kanye namazinga omhlaba we-ISO wokumisa (incwadi "P" ekumaka).

Abashayeli abasebenzela izimoto zabo bebodwa abakwesabi ngisho ukudweba umzimba. Inqubo eyinkimbinkimbi, noma kunjalo, idinga ulwazi olukhulu, isibonelo, yiziphi izinombolo ze-sandpaper ezidingekayo ukudweba, ukugaya, ukupholisha imoto. Isihloko kufanelekile ukusihlola.

Izinhlobo zezikhumba ezilumayo

I-sandpaper (i-sandpaper) iyimpahla yokugaya yokunikeza isakhiwo esithile phezulu ngaphambi kokudweba nokusilethela ukuba kukhanye futhi kucwebezele ngemva. Ngaphambi kokuba uthole inombolo ye-sandpaper yokudweba imoto, udinga ukuqonda izinhlobo zezinto ezilimazayo. Ukuhlukaniswa kuhambisana nesisekelo, lapho i-abrasive isetshenziswa nge-glue noma i-mastic.

Kunezinhlobo ezilandelayo zezikhumba:

• Iphepha. Lokhu kuyindlela evamile futhi eyongayo, ekuvumela ukuthi usebenzise ama-chips amancane kakhulu ephepheni.
• Indwangu esekelwe. Le sandpaper iyanwebeka futhi ayigugi, okuthinta intengo.
• Kuhlanganiswe. Inhlanganisela yezinketho ezimbili zangaphambilini ibambe izakhiwo ezinhle kakhulu: ukuguquguquka - kusukela kusisekelo sendwangu, kungenzeka ukusebenzisa i-abrasive emihle - ephepheni.

Indwangu e-abrasive ngesisekelo sendwangu

I-sandpaper ikhiqizwa ngamashidi noma imiqulu. Ukukhetha inombolo efanele ye-sandpaper yokugaya imoto, kufanele uqale ubheke umqondo we "grain".

Ukumaka iGrit

"Okusanhlamvu" - powder abrasive - abe nezici ezahlukene:

• usayizi
• impahla yokukhiqiza;
• ukuminyana kohlelo lokusebenza ngeyintshi yesikwele ngayinye.

Le mingcele ikusiza ukuthi ukhethe inombolo edingekayo ye-sandpaper yokupholisha imoto.

Igrithi ikalwa ngama-micrometers (µm). Ukuhlukaniswa kwe-emery material kuya ngosayizi wezinhlayiyana ze-abrasive:

• Okukhulu. Ukuqokwa kwezinombolo - kusuka ku-12 kuya ku-80. Iphepha lisetshenziselwa umsebenzi wokulungiselela onzima, ukucubungula okuyinhloko kwezindawo ezilungisiwe. Izinhlamvu ezinkulu zikhipha ama-chips, amashisela.
• Isilinganiso. Iqokwe ngezimpawu kusuka ku-80 kuya ku-160, isetshenziselwa ukulungisa kahle izingxenye zomzimba, ukulungiswa kokugcina kwe-putty. Kusukela kulezi zinkomba ze-granularity, inombolo ye-sandpaper yokudweba imoto ikhethiwe.
• Encane. Inani elikhulu kakhulu le-powder abrasive ligxilwe ku-intshi yesikwele, kusukela ngosayizi kusuka ku-160 kuya ku-1400. Ngaphakathi kwale mingcele, kunenombolo ye-sandpaper yokupholisha imoto, okuzodingeka esigabeni sokuqeda umdwebo.

Isithombe sibonisa itafula le-sanding grits lezinto ezihlukahlukene.

Ithebula le-Sanding grit lezinto ezihlukahlukene

Ithebula libonisa ukuthi izinombolo ze-sandpaper zokukhumula ngemuva kokufaka imoto ziphakathi kuka-180 kuya ku-240.

Uhlangothi olungemuva lwemiqulu, amashidi noma amasondo okugaya akhethekile amakiwe.

Ukumaka i-sandpaper

Ihambisana ne-Russian GOSTs ka-1980 no-2005 (igama lezinhlamvu "M" noma "H") kanye namazinga omhlaba we-ISO wokumisa (incwadi "P" ekumaka).

Ama-abrasives asetshenzisiwe

Njengemvuthuluka (i-powder) yesisekelo, abakhiqizi basebenzisa amatshe, isihlabathi, i-shell rock kanye nezinto zokwenziwa ze-polymer.

Ama-abrasives adumile:

• Ihalananda. Umsuka wemvelo unikeza ukuthamba nokunwebeka ku-emery, evame ukusetshenziselwa ukucubungula izinkuni.
• I-silicon carbide. Impushana ejwayelekile yendawo yonke yokusebenza ngopende, izindawo zensimbi.
• I-Ceramic crumb. Kudingeka impahla enamandla kakhulu ukuze kwakhiwe imikhiqizo.
• I-Zircon corundum. I-abrasive resistant ngokuvamile yenziwa ngendlela yebhande lama-grinders.
• I-Alumina. Ukuqina kwe-abrasive kuyivumela ukuthi isetshenziselwe ukulola imiphetho yokusika.

I-Silicon Carbide Sandpaper

Lapho ukhetha izinombolo ze-sandpaper zokudweba izimoto, naka i-silicon carbide abrasive.

Indlela yokwenza sandpaper ngendlela efanele

Ubuchwepheshe bulula. Into esemqoka ukunemba nokubekezela. Ukuze wenze isihlabathi, udinga ukuthatha izinombolo ezahlukene ze-sandpaper zokudweba imoto - kusukela kwencane kakhulu kuya kwenkulu kakhulu yokugaya.

Izici zokucubungula

Sebenza ebhokisini elihlanzekile, elomile nelikhanyiswe kahle. Yenza ukuhlanza okumanzi, vala phansi kanye nezindonga nge-plastic wrap.

Lungiselela ama-ovaloli, vikela izitho zokuphefumula nge-respirator, amehlo anezibuko. Qoqa imvuthuluka eyenziwe ngesikhathi senqubo ye-sanding nge-vacuum cleaner.

Umsebenzi wokulungiselela

Umphumela wokugcina wokufaka amabala ngokuqondile uncike esigabeni sokulungiselela:

1. Geza imoto yakho endaweni yokugeza izimoto kuqala.
2. Egaraji, susa wonke amapulasitiki, izingxenye ze-chrome ezingahlobene nokudweba.
3. Geza futhi imoto nge-shampoo, sula yomile, degrease ngomoya omhlophe.
4. Hlola umzimba, hlola izinga lomsebenzi. Kungenzeka ukuthi akuyona yonke indawo okuzodingeka ihlanzwe, ipendwe futhi ifakwe isihlabathi.
5. Philisa izindawo ezidingayo, ziqondise.

Umsebenzi wokulungiselela

Bese uhlanza igumbi futhi.

Izici zokugaya ngesandla

Ukwenza lula umsebenzi, lungiselela i-sanding pad kusengaphambili - ibhulokhi enabanikazi be-sandpaper. Ungathenga idivayisi noma uzenzele ngokwakho ezintweni ezithuthukisiwe: ucezu lokhuni, isipontshi esiqinile.

Isigaba sokuqala sokukhumula umzimba womakhenikha bezimoto nabadwebi sibizwa nge-matting. Kungcono kakhulu ukupholisha ezindaweni ezinkulu usebenzisa igrinder, kodwa lapho ithuluzi lingakwazi ukukhasa, kungcono ukulihlikihla ngesandla. Inombolo ye-sandpaper yokuhlanganisa imoto yi-P220-240.

Ngemva kwale nqubo, amazinyo, imihuzuko, nokunye ukukhubazeka kuvezwa ngokucacile. Gijimisa isikhumba ngaphansi kwenombolo P120: izokhipha imihuzuko, imiphetho ebukhali kapende, ihlanze ukugqwala.

Sanding isandla

Umgomo wenqubo kulesi sigaba akuyona indawo ebushelelezi. Ukuze uthole ukunamathela okungcono kwe-putty ngensimbi yomzimba, ama-micro-scratches afanayo kufanele ahlale ekugcineni.

Ungakhohlwa ukucofa udoti. Lapho ubuso bulungiswa, i-putty it, yiyeke yome. Khetha inombolo efanele ye-sandpaper yokugaya ngemva kokufaka imoto, hamba kuwo wonke amaphaneli.

Ungqimba olulodwa lwe-primer alwanele, ngakho-ke vala umzimba ngelesibili, uma kunesidingo, kanye nesendlalelo sesithathu, isikhathi ngasinye sanding indawo yokulungisa.

Indlela yokugaya i-putty emotweni nge-grinder

Umphumela omuhle kakhulu uzotholakala nge-eccentric orbital sander. Ithuluzi lamandla lisebenziseka kalula: udinga nje ukunamathisela amasondo okugaya akhethekile anezimbobo ezikhulayo emshinini. Bese ushayela phezulu ezindaweni ezikhethwe ngokungahleliwe.

Imishini ihlinzekwa ngeqoqo lothuli elimunca izinsalela ze-abrasive. Kubalulekile ukukhetha inombolo efanele ye-sandpaper kanye nosayizi wokusanhlamvu wokugaya inhlabathi emotweni, futhi isivinini kanye nekhwalithi kuzonikezwa idivayisi.

Ukugaya nge-grinder

Ezindaweni ezinkulu futhi ezibushelelezi, i-sander yebhande izokwenza. Namathisela i-sandpaper kuyo ngendlela yendwangu. Okulandelayo, vula idivayisi futhi, ubambe isibambo, uyishayele ngendlela efanele. Kuyafaneleka ukucabangela amandla ethuluzi: umshini ungagaya ungqimba olukhulu lwensimbi.

Amathiphu ambalwa engeziwe

I-sanding yekhwalithi ephezulu mhlawumbe umzuzu oyinhloko wokulungiselela ngaphambi kokugcoba. Lapha isipiliyoni kanye ne-intuition kudlala indima enkulu.

Amathiphu avela koomakhenikha bezimoto abanolwazi:

• Uma kungenjalo umzimba wonke udinga ukugaywa isihlabathi, vala indawo eseduze nendawo yokulungisa nge-masking tape.
• Lapho uhlela amasayithi okubuyisela, ungesabi ukuthwebula indawo ebanzi kunesici.
• Ngaphambi kokufaka isihlabathi, phatha i-putty ngonjiniyela omnyama: izokhombisa ukuthi ungangeza kuphi ama-putty.
• Gcina futhi usebenze ngezikhumba ezimahhadlahhadla, eziphakathi nendawo nezicolekileyo.
• Kudingekile ukugaya insimbi kanye ne-putty ngomzamo ohlukile womzimba: isendlalelo se-primer sihlala sithambile futhi sizosulwa nje ekushisekeleni ngokweqile.
• Qala nge-sandpaper enohlamvu oluqinile, bese ukhulisa inani le-sandpaper yokupholisha imoto ngamayunithi angama-80-100.

Ngesikhathi sokusebenza, susa uthuli, wenze ukuhlanza okumanzi.
