Niaj hnub nimno computer graphics tsis tuaj yeem hloov ua haujlwm ntawm cov kws ua yeeb yam. Lawv tseem tsim nrog xaum rau ntawm daim ntawv. Cov "cov cuab yeej" ntawm lawv txoj haujlwm tau hloov pauv me ntsis, nws tau dhau los ua qhov yooj yim thiab txhim khu kev qha. Cov cwj mem tsis tu ncua, collet, tsis siv neeg, xim lossis yooj yim - lawv txhua tus xav tau thiab nrhiav lawv cov neeg siv khoom.

History of Creation

Tus qauv ntawm kev sau ntawv tau tshwm sim nyob rau xyoo pua kaum peb. Ntawm chav kawm, nws tsis dais ntau npaum li cas rau cov qauv niaj hnub - ib tug nyias nyiaj hlau ntawm tus kov yog txuas nrog soldering. Ntau los yog tsawg dua li niaj hnub mem hluav tshwm nyob rau hauv lub xyoo pua puas xyoo. Cov kws ua yeeb yam tau txuas cov graphite rods ntawm cov laug cam nqaim, khi lawv thiab qhwv lawv hauv ntawv. Yog li txhais tes tsis txhob qias neeg, thiab nws yooj yim dua los tuav nws.

Thaum kawg ntawm lub xyoo pua kaum yim, Fabkis tus kws tshawb fawb thiab tus tsim khoom Nicolas Jacques Conte tau tsim cov qauv niaj hnub no. Ntxiv mus, nws tau txhim kho, thawj Lothar von Fabercastle daws qhov teeb meem ntawm dov los ntawm kev thov cov khoom hexagonal.

Txoj hauv kev muaj txiaj ntsig ntawm Asmeskas rau lub neej ua rau Alonso Townsend Cross xav txog kev siv nyiaj ntau dua ntawm graphite pas nrig. Thaum lub sijhawm ua haujlwm, ob feem peb ntawm cov khoom raug muab pov tseg thaum nws ua kom zoo. Nws "dab" cov hlau lead hauv ib lub raj hlau thiab rub nws tawm raws li qhov xav tau ntawm qhov ntev uas xav tau. Ib tug cwj mem yog "tus ntxhais xeeb ntxwv" thiab qhov yooj yim tshaj plaws niaj hnub tsim ntawm tib lub raj hlau.

Txoj Cai Ua Haujlwm

Collets - Zange, txhais los ntawm German, txhais tau tias yog lub cuab yeej kho cov khoom siv cylindrical nrog lub clamp. Daim ntawv thov yog dav heev: nyob rau hauv scalpels, paib, ntawm hlau thiab woodworking tshuab, thauj tog rau nkoj bolts, ntau yam kev tsim kho cov cuab yeej uas txhim khu kev qha fixation yog yuav tsum tau.

Cov cwj mem tau txais nws lub npe los ntawm cov txheej txheem uas siv hauv nws qhov chaw tsim khoom. Qhov no yog ib qho cuab yeej ntawm ob peb "petals" nruj nreem qhwv ib ncig ntawm lub stylus. Nrog kev pab los ntawm lub caij nplooj ntoos hlav, los ntawm nias lub pob nyob rau sab sauv ntawm cov khoom, lub collet qhib thiab koj tuaj yeem thawb cov hlau lead mus rau qhov xav tau ntev. Tom qab tso lub pob, lub "petals" kaw thiab tuav lub stylus nyob rau hauv txoj hauj lwm xav.

A collet mem hluav (2 hli yog qhov ntau tshaj plaws, muaj los ntawm 0.1mm txog 5mm) tuaj yeem ua los ntawm ntau yam ntaub ntawv. Muaj ntoo, hlau, yas, ua ke rooj plaub. Rau kev yooj yim, cov khoom siv roj hmab tuaj yeem ntsia tau rau hauv thaj chaw girth. Lawv nthuav lub cev ntawm tus cwj mem thiab tsis txhob cia nws plam hauv koj txhais tes. Lawv kuj txawv ntawm qhov zoo ntawm cov lwv.

Ntau yam

Ib lub cuab yeej tsim los kos cov duab uas koj tuaj yeem hloov tus pas nrig graphite ib tus lej tsis kawg yog hu ua mem hluav. Siv rau kev kos duab, sau ntawv, kos duab. Muaj ob hom:

• tsis siv neeg xaum;
• cwj mem.

Thiab, qhov tsis siv neeg muab faib ua ntau hom, nyob ntawm seb lub tshuab uas pub tus pas nrig:

• ntsia, pub los ntawm tig ib sab ntawm lub cev;
• shake-nias (co los yog nias) pub tus pas nrig koj yuav tsum co tus cwj mem;
• rau tus tub nkeeg, lub khawm pub mis yog nyob ntawm sab ntawm lub cev hauv thaj chaw tuav.

Qhov ua tau zoo tshaj plaws yog cov khoom lag luam uas cov txheej txheem qhia tsis yog ua los ntawm cov yas. Lub zog siab tuaj yeem ua rau tus pas nrig nkag mus rau hauv rooj plaub.

Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws.

Cov neeg siv khoom yog cov kws tshaj lij tshaj lij. Cov khoom uas lawv siv yuav tsum ua tau raws li cov lus tshaj tawm zoo. Nov yog ob peb yam yooj yim uas tus cwj mem collet muaj:

• tsis xav kom ntse;
• tus pas nrig tuaj yeem "rub" hauv rooj plaub thiab tsis txhob ntshai ntawm kev tawg thaum thauj;
• koj tuaj yeem kho qhov tuab ntawm cov hlau lead;
• muaj ib lub tshuab hloov tau;
• xaum cov cim tau ntev dua li tus lej cim;
• kev ntseeg siab thaum nias.

Cov cuab yeej no siv los ntawm ntau tus neeg: cov tub ntxhais kawm,cov tub ntxhais kawm, cov kws tshaj lij tsim khoom. Nws kuj yog siv los ntawm cov kws ua yeeb yam, ob qho tib si cov tub txawg thiab amateurs. Nws tso cai rau koj kos ib qho contour nrog qhov dav ntawm tsuas yog 0.2 hli.

Ntau lub hom phiaj txiav txim siab ntau yam kev xaiv. Mechanical collet cwj mem yog tsim los ntawm ntau lub tuam txhab paub zoo Paper Mate (Mexico); Penac (Nyiv), Pilot (Nyiv), Parker (USA), Attache, BIC (Fabkis), Pentel (Nyiv), Koh-I-Noor (Czech koom pheej), ICO (Hungary), Rotring (Lub teb chaws Yelemees). Ib tug neeg kho tshuab cwj mem ntawm lub ntiaj teb nto moo hom yuav yog ib qho khoom plig zoo rau kev ua koob tsheej. Ib txheej ntawm cov cwj mem, dawb lossis xim, yuav txaus siab rau cov neeg laus thiab menyuam yaus.
