CHM Machinery----Lub hauv paus chiv keeb ntawm daim ntawv loj

       Daim ntawv, raws li ib qho tseem ceeb ntawm cov ntaub ntawv kis tau tus mob thiab sau cia, muaj ib tug deb-mus txog qhov tseem ceeb thiab nthuav keeb kwm nyob rau hauv nws loj specification.

ISO 216 tus qauv, uas suav nrog A4 qhov loj me, yog tus qauv thoob ntiaj teb rau daim ntawv loj. Nws yog siv thoob plaws ntiaj teb tshwj tsis yog hauv North America thiab qhov chaw ntawm Central thiab South America, qhov twg North American daim ntawv loj xws li "Letter" thiab "Legal" yog siv.Cov txheej txheem thoob ntiaj teb rau lub hnab ntawv yog C series ntawm ISO 269.

Nyob rau hauv cov ntawv loj, cov qauv loj tshaj plaws yog cov ntawv loj thoob ntiaj teb, xws li A4, A3, thiab lwm yam. Ntawm lawv, A4 loj (210mm × 297mm) yog siv dav hauv txhua hnub chaw ua haujlwm thiab luam ntawv.

 

 

Lub hauv paus chiv keeb ntawm cov qauv ntawv loj tuaj yeem taug qab mus rau lub teb chaws Yelemees hauv xyoo pua 19th. Nyob rau lub sijhawm ntawd, txhawm rau txhawm rau tsim cov qauv tsim thiab siv cov ntawv, txhim kho kev tsim khoom thiab txo cov khoom pov tseg, cov neeg tsim cov txheej txheem ntawm daim ntawv loj raws li kev ua lej. Lub hauv paus ntawm tus qauv no yog tias tom qab folding sab ntev ntawm daim ntawv hauv ib nrab, qhov loj ntawm daim ntawv tau txais yog tib yam li ntawm daim ntawv qub.

Siv daim ntawv A series ua piv txwv, A {{0}} qhov loj yog txhais tias thaj tsam ntawm 1 square meter thiab qhov piv ntawm 1: √2. Muab daim ntawv A0 nyob rau hauv ib nrab ntawm sab ntev kom tau A1 daim ntawv; quav nws hauv ib nrab dua kom tau A2 daim ntawv, thiab lwm yam. Qhov kev txawj ntse ntawm qhov kev tsim no yog tias txawm tias daim ntawv yog folded thiab faib li cas, nws cov proportions tseem tsis hloov pauv, uas ua rau muaj txiaj ntsig zoo rau daim ntawv txiav, luam ntawv thiab khi.

Qhov kev tsim no raws li kev ua lej sib piv tsis tsuas yog ua rau kev tsim khoom thiab siv cov ntawv tsim nyog thiab ua haujlwm tau zoo, tab sis kuj txhawb kev hloov pauv thiab hloov pauv ntawm ntau qhov sib txawv. Niaj hnub no, A series ntawv loj tau dhau los ua ib qho ntawm cov qauv thoob ntiaj teb thiab tau siv dav hauv ntau qhov chaw xws li chaw ua haujlwm, luam ntawv, thiab tsim.

Txawm hais tias tus qauv ntawm daim ntawv loj zoo li qub, nws muaj cov crystallization ntawm tib neeg kev txawj ntse thiab txhawb kev nthuav tawm thiab kev sib pauv ntaub ntawv zoo heev.
