Cov ntawv luam tshwj xeeb rau chaw ua haujlwm siv tau cais raws li cov ntawv thiab tus lej ntawm cov ntawv luam tawm 1 thiab 2 txheej ntawm cov ntawv tshaj tawm nqaim, thiab ntawm chav kawm muaj 3 Txheej thiab 4 txheej. ; Feem ntau siv dav-kab luam ntawv luam ntawv thiab 381-1, 381-2 thiab lwm yam. Piv txwv li: 241-2 yog hais txog carbonless luam ntawv ntawv (tseem hu ua siab siab rhiab ntawv). Tsuas tuaj yeem luam tawm ntawm lub tshuab luam ntawv stylus stylus. 241 sawv rau: 9.5 nti, uas yog qhov dav ntawm daim ntawv. Hom ntawv no tseem yog hu ua 80-kem ntawv luam ntawv, uas yog hais, tus neeg ib txwm muaj 80 tus cim nyob hauv ib kab. Lub ntsiab siv kev siv ntawm cov ntaub ntawv no yog: Outbound / Inbound xaj, ceeb toom, ntawv txais nyiaj. Siv tau rau: Ntug dej, Tsev Kho Mob, thiab lwm yam.
Carbonless luam ntawv luam ntawv, tseem hu ua kev ua siab rhiab daim ntawv, yog tsim los ntawm cov ntawv saum toj (CB) thiab hauv qab ntawv (cf). Nws siv lub ntsiab cai ntawm kev siv tshuaj lom neeg ntawm cov xim tsim tus neeg saib xyuas ntawm microCape thiab cov kua txiv ntoo hauv cov xim tsim tus neeg sawv cev txheej. Thaum lub sijhawm luam ntawv, cov luam ntawv luam tawm nias daim ntawv saum npoo kom ua tiav cov txiaj ntsig xim kev cuam tshuam. Cov kev sib xws thiab feem ntau siv cov txheej txheem xim yog 2 txog 6 txheej.
Thaum twg cov khoom siv carbon tsis muaj carbonless luam ntawv, them sai sai rau cov ntawv sab nraud yog puas los yog deformed sab nraud, nws yuav ua rau daim ntawv sab hauv kom tsim xim). Qhib cov pob sab nraud thiab tshawb seb puas muaj daim ntawv pov thawj, seb nws puas yuav ua tau zoo li koj xav tau (seb nws puas tuaj yeem sau ob peb lo lus nyob rau hauv ib txwm sau , Tom qab ntawd saib cov xim rendering ntawm txheej dhau los). Paub meej tias cov specifications ntawm daim ntawv luam ntawv yog dab tsi koj yuav tsum tau zam kom tsis tsim nyog pov tseg thiab teeb meem.
Cov ntaub ntawv tshwj xeeb ntawm cov siv carbon tsis muaj carbonless luam ntawv yog 80 kab ntawv lossis 132, ntev li cov kev sib npaug tshwj xeeb, qhov ntsug sib npaug, thiab lwm yam). Feem ntau siv yog 80 kab ntawv, thiab qhov loj yog: 9.5 nti X 11 nti (nrog lub qhov ntawm txhua sab, thiab 0.5 nti ntawm txhua sab) kwv yees sib npaug rau 241 hli X 279 hli. 80 txhua ntawm daim ntawv feem ntau muab faib ua peb hom tshwj xeeb:
1: Puv nplooj (9.5 nti X 11 nti).
2: ib nrab (9.5 nti X 11/2 ntiv).
3: ib feem peb (9.5 nti X 11/3 nti).
Tom qab qhib lub thawv, thov mloog nws. Yog tias nws tsis yog siv rau lub sijhawm ntev, nws yuav tsum muab tso rau hauv lub hnab ntim khoom qub kom tsis txhob muaj noo noo thiab puas. Yog tias nws muaj carbon tsis muaj hom luam ntawv, ceev faj kom tsis txhob muab cov khoom ntse los ntawm cov khoom sib xyaw lossis sab nraud kom tsis txhob muaj xim, thiab lwm yam, cuam tshuam rau kev siv. Ua ntej siv cov khoom, paub meej tias txoj haujlwm ntawm lub tshuab luam ntawv. Thaum luam ntawv nyob rau hauv ntau txheej, sim tsis txhob siv cov tshuab ceev ceev los xyuas kom meej ntawm luam ntawv sau. Nco ntsoov tias cov ntaub ntawv yuav tsum tau muab cais cais, yog tias lawv yuav tsum muab khaws cia ua ke, zam kev sib xyaw. Nws yuav tsum tau tiv thaiv los ntawm lub teeb, dej, roj, kua qaub thiab alkali. Tsuav nyob rau hauv txoj cai ib puag ncig, Carbon-luam ntawv luam ntawv tuaj yeem khaws cia rau tsawg kawg 15 xyoos. Yog tias muaj ib daim ntawv jam thaum luam tawm, kuaj seb puas tsim nyog, txawm nws yog mus raws li lub tsheb laij teb, thiab nws yog ib lub taub hau luam tawm kom haum rau cov ntawv txheej ntawm cov ntawv.
Tau Txais Cov Ntawv Luam Ntawv lossis Tiaj Tus Laub Tshuab Luam Ntawv, thiab lwm yam yog tsim nyog rau kev siv cov khoom siv ntau li luam cov ntawv. Cov tshuab luam ntawv no raug tsim kom cov luam ntawv tsis yog khoov hauv lub tshuab, luam ntawv luam ntawv yog tiaj, thiab lub tshuab luam ntawv kuj tseem ceeb dua.
Cov ntawv carbonless tsis qhia xim lossis tsis meej (tshwj tsis yog rau cov ntawv zoo), yuav daws nws li cas?
(1) Tsis muaj kev txhim kho kob yuav tshwm sim los ntawm kev thauj cov ntawv luam tawm sab hauv, cia li rov xa ntawv.
(2) Qhov ua rau tsis paub meej xim tej zaum yuav tsis muaj cov ntawv luam tawm tsis txaus siab lossis cov koob txhaj tawm hauv lub taub hau. Koj tuaj yeem nce lub zog luam tawm los tshawb xyuas seb puas muaj koob yees duab.
(3) Kev txhim kho xim yog cov txheej txheem tshuaj lom neeg, tshwj xeeb tshaj yog thaum lub caij ntuj sov uas muaj qhov kub thiab txias, thiab qhov ntsuas dej ntshiab tsis tuaj yeem pom tam sim ntawd tom qab luam ntawv, uas yog qhov qub tshwm sim.
ZHongwen ntawv tsim txhua hom kev siv cov ntawv thermal thiab cov pob roj carboness. Yog tias koj xav tau, thov qhia rau peb paub. Hoobkas ncaj qha muag, kev paub tseeb tias muaj txiaj ntsig zoo, kev paub tseeb tsawg.
