Ipensela ye-Collet - ithuluzi lomculi elinokwethenjelwa

Ihluzo zekhompyutha zanamuhla azikwazanga ukubuyisela ngokuphelele umsebenzi wabaculi. Basakakha amapensela ephepheni. "I-Cannon" yomsebenzi wayo ishintshile kancane, isibe esikahle futhi sinokwethenjelwa. Ipensela evamile, ikhalenda, okuzenzakalelayo, umbala noma elula - konke kudingekile futhi bathola amakhasimende abo.

Umlando wendalo

Umboniso wethuluzi lokubhala uqobo lwavela ngekhulu leshumi nantathu. Yiqiniso, yayifana neyodwa imodeli yanamuhla - ucingo oluthile lwesiliva esibambini lwaluhlanganiswe ngokuhlunga. Okuncane noma okuncane okukhumbuza ipensela yanamuhla yabonakala ngekhulu leshumi nesikhombisa. Abaculi benza izintambo ze-graphite phakathi kwamabhodi amancane, aboshwe futhi bahlanganiswe ngephepha. Ngakho ungatholi izandla ezingcolile, futhi ukugcina kube lula kakhulu.

Ekupheleni kwekhulu leshumi nesishiyagalombili, ososayensi waseFrance nomsunguli uNicolas Jacques Comte wasungula imodeli yanamuhla. Ngokuqhubekayo kwathuthukisiwe, uLothar von Faberkastl wokuqala waxazulula inkinga yokuguqa, enikeza umumo womkhiqizo we-hexagonal.

Indlela enengqondo yabantu baseMelika empilweni yabangela u-Alonso Townsend Cross ukuba acabange ngokusetshenziswa kakhudlwana kokunciphisa intonga ye-graphite. Ngesikhathi sokusebenza, izingxenye ezimbili kwezintathu zomkhiqizo ziphonswa ngaphandle ngenkathi zibukhali. "Wafihla" ukuhola ebhukwini lensimbi futhi wasixosha njengoba kudingekile ubude obufunayo. I-Pencil Collet - "umzukulukazi" nomklamo wesimanje ongcono we-tube efanayo yensimbi.

Isimiso sokusebenza

I-Zang - Zange, ngesihumusho sesiJalimane, lisho idivaysi yokulungisa izinto ezincibilikisiwe ngosizo lwe-clamp. Uhlelo lokusebenza lukhulu kakhulu: ku-scalpels, ngezibilini, kumishini yensimbi- nokhuni, izinkinobho ze-anchor, amathuluzi ahlukene wokwakha lapho kudingeka khona ukulungiswa okuthembekile.

Ipensela ye-collet yabizwa ngegama layo elisetshenziselwa ukwenziwa kwalo. Le divayisi iqukethe "amakholi" ambalwa, ngokuqinile ukuqonda ukuhola. Ngosizo lwentwasahlobo, ucindezele inkinobho phezulu komkhiqizo, ikholomu ivuleka futhi ungadlulisa ukuholela ekudeni okufunayo. Ngemuva kokukhipha inkinobho, "ama-petals" avaliwe bese ubamba ukuhola endaweni efunayo.

Ipensela yamakholomu (2 mm - ejwayelekile kakhulu, ivela ku-0.1 mm kuya ku-5 mm) ingenziwa ngezinto ezihlukahlukene. Kukhona izinkuni, zensimbi, ipulasitiki, izikhonkwane ezihlangene. Ukuze kube lula, ukufakelwa kwerejabhali kungafakwa endaweni ye-girth. Banda ukwakhiwa kwepensela futhi ungawuvumeli ukuba ulayishe esandleni. Ihluka emkhakheni we-eraser.

Izinhlobo

Ithuluzi elenzelwe ukudweba isithombe lapho inani elingapheli lezinkathi zenduku yegraphite lingashintshwa libizwa ngokuthi ipensela yomshini. Isetshenziselwa ukudweba, ukubhala, ukudweba. Kunezinhlobo ezimbili:

• Ipensela ngokuzenzakalelayo;
• Ikholomu yepensela.

Ngokuzenzekelayo, i-othomathikhi ihlukaniswe yaba izinhlobo eziningana, kuye ngokuthi indlela edla induku:

• Isikrini, ukondla ngokushintsha noma iyiphi ingxenye yomzimba;
• Shake-press (shake noma cindezela) ukondla induku okudingayo ukuze ugubha ipensela;
• Ukuze uvila, inkinobho ehlinzeka ukuhlinzeka kokuhola itholakala eceleni komzimba endaweni yebhande.

Imikhiqizo ewusizo kunazo zonke yilabo inqubo yokuqondisa engenziwanga ngepulasitiki. Ukucindezeleka okuqinile kungabangela ukuhoxiswa kwenduku endlini.

Izinzuzo

Abathengi yizazi ezizimele kakhulu. Izimpahla abazisebenzisayo kumele zihlangabezane nezimfanelo eziveziwe. Nazi ezimbalwa zezintandokazi ukuthi ipensela yekholomu inezi:

• Akudingi ukuqinisa;
• Induku ingasetshenziswa "ukuhoxiswa" emzimbeni futhi ungesabi ukuhlukana kwayo kunoma yikuphi ukuhamba;
• Ungakwazi ukulungisa ubukhulu bokuhola;
• Ukuba khona kwe-eraser esikhundleni;
• Umkhondo ovela ipensela uhlala isikhathi eside kunokungena kwinki;
• Ukuthembeka okuphezulu uma ucindezelwe.

Le divayisi ijabulela inani elikhulu labantu: abafundi, abafundi, ochwepheshe ekukhiqizeni. Sebenzisa kanye nabaculi, bobabili abaqeqeshiwe kanye nabalingisi. Ikuvumela ukuba usebenzise umjikelezo ngobubanzi obungama-0.2 mm kuphela.

Ukuqokwa kwamanxeba okuchaza okuningi kuchaza nokukhetha okuhlukahlukene. Amapensela amakhemikhali amashini akhiqizwa izinkampani eziningi ezaziwayo i-Paper Mate (Mexico); IPerac, Pilot, Parker, Attache, BIC, Pentel, Koh-I-Noor, ICO, Rotring, eJalimane. Ipensela yomshini womhlaba odumile emhlabeni uyoba isipho esihle kunazo zonke kunoma imuphi umkhosi. Iqoqo lamapensela e-colander, elula noma enemibala, izojabulisa kokubili omdala nomntwana.
