Txoj Kevstructures

Txhua yam ntawm cov duab los qhia muaj ib yam - txheej txheej.

Cov txheej txheej sab nrauv (hauv qab thiab sab saum toj) muaj cov tshuaj dawb los yog tsis muaj tshuaj dawb, ntoo pulp lossis ntawv pov tseg ua ntej bleached. Thiab cov khoom ntim sab hauv yog tsim los ntawm cov khoom siv pheej yig dua: cov khoom pov tseg, cov ntawv pov tseg, cov ntawv pov tseg tsis muaj tshuaj dawb.

Nws yuav tsum tau muab sau tseg tias cov khaubncaws sab nraud povtseg sab saud tuaj yeem muab faib ua ob lossis peb txheej. Tus nqi ntawm cov khoom yog txiav txim siab los ntawm cov khoom siv raw thiab cov yam ntxwv ntawm cov khoom tsim nyog. Raws li ntau lub zog, cov khoom siv tau raug cais raws li kev cai.

Kev faib tawm ntawm cov duab los qhia

Muaj ntau txoj kev xaiv, suav nrog German thiab European. Hauv peb lub tebchaws koj tuaj yeem pom cov no:

• Los ntawm cov khoom siv raw: pulp (daim duab los ntawm cov ntaub ntawv nyoos), cov ntawv pov tseg, kraft cardboard.

Kev faib tawm European muaj tsab ntawv tsim thiab cais cov duab los qhia raws li kev tsim khoom.

Txhua yam rau txhua tusdaim ntawv thov yuav tsum muaj tej yam ntxwv.

Properties

GOST R 53636-2009 muab cov npe tag nrho ntawm cov yam ntxwv ntawm cov duab los qhia thiab ntawv nrog rau cov ntaub ntawv tswj hwm. Cov tseem ceeb suav nrog cov hauv qab no:

• white;
• ntub zog;
• humidity (muaj dej hauv cov khoom);
• durability;
• hardness;
• flexural txhav;
• fat permeability;
• zog;
• nyhav;
• ntom, thiab lwm yam.

Raws li koj tuaj yeem pom, txhawm rau xaiv qee hom duab los qhia rau ib daim ntawv thov tshwj xeeb, muaj ntau yam ntawm cov yam ntxwv raug coj mus rau hauv tus account. Qhov twg? Qhov no yuav tham ntxiv.

Tshuaj ntsuab. Hom thiab cov khoom

Cia peb xav txog qhov kev faib tawm tseem ceeb los ntawm cov khoom siv raw ua ke nrog cov khoom:

• Cellulose cardboard. Distinctive feature: nws tsim cov luam ntawv zoo. Thiab txij li thawj cov khoom siv raw yog siv, thaj chaw ntawm daim ntawv thov yog khoom noj khoom haus, lub teeb kev lag luam, thiab luam ntawv. Cov khoom zoo li no txawv ntawm tus nqi siab thiab muaj zog zoo. Yog li ntawd, lawv tau siv rau cov khoom tshwj xeeb, luam ntawv thiab ntim khoom.
• Khib nyiab cardboard. Nws muaj tsawg rigidity thiab tus nqi qis. Yuav siv tau rau hauv ntau yam dej num. Thaum xaiv, koj yuav tsum xaiv qhov tuab dua kom thaum tus nqi ntawm cov khoom txo qis, cov yam ntxwv ntawm lub zog tau khaws cia.



Ntau zaus siv rau cov khoom siv. Cov khoom noj khoom haus xav tau ntxivKev sib cais ntawm cov khoom los ntawm kev sib cuag nrog lub ntim.

• Kraft daim ntawv. Hais txog kev tsim cov pulp ntshiab. Muaj cov yam ntxwv muaj zog ntxiv ntawm tus nqi qis. Ib qho tshwj xeeb - sab hauv yog unbleached.

Special Applications

Cov me nyuam muaj tswv yim thiab tsim qauv yog ob qho kev siv rau cov duab los qhia xim.

Thiab yog tias ua ntej nws tau nthuav tawm hauv daim ntawv pleev xim rau, hnub no ntau yam tuaj yeem ua rau lub siab xav paub ntau tshaj plaws thiab kev xav. Dab tsi ntawm cov xim cardboard muaj?

• Holographic. Cov khoom siv txawv txawv, nws nthuav dav kev ua haujlwm rau ob tus neeg tsim qauv thiab menyuam yaus.
• Nkauj hmoob. Nws nqa cov haujlwm ntawm cov xim, thiab txawm yog voluminous. Cov khoom siv no tsis yog siv rau cov khoom siv tes ua nkaus xwb, tab sis kuj rau cov khoom ntim tshwj xeeb, vintage sab hauv kho kom zoo nkauj.

Hom duab los qhia rau ntim

thaj chaw no tsim nyog saib dua. Cardboard li ntim tau khov kho nkag mus rau tib neeg lub neej.

Thaum xaiv cov khoom ntim, xyuam xim rau cov yam ntxwv hauv qab no:

• hardness;
• zog;
• barrier zog;
• puffiness;
• nyhav;
• raw khoom.

Qhov nrov ntawm lub thawv ntim khoom yog vim nws qhov zoo.

txiaj ntsig

Qhov zoo ntawm cov ntawv ntim khoom suav nrog:

• Sustainability. Cov ntoo fibers lossis cov ntawv pov tseg yog siv. Hauv thawj kis, kev saib xyuas kev nyiam huv, qhov thib ob, thaj chaw hav zoov tau khaws cia los ntawm kev rov ua dua tshiab.
• Lub teeb yuag, lub zog, nruj. Thaum muab piv nrog cov ntaub ntawv xws li cov thawv yas, cov thawv hlau, cov duab los qhia yeej qhov hnyav, uas txuag nyiaj ntawm kev thauj mus los.
• Yooj yim cia. Ntau tus neeg siv cov thawv ntim khoom ntim ntau zaus. Thiab thaum lawv tsis xav tau, lawv nteg tawm thiab tau cov ntawv tiaj tus uas tsis siv ntau qhov chaw.
• Recycling. Cov khoom no yog qhov tshwj xeeb uas nws tuaj yeem rov ua dua lossis tsuas yog pov tseg yam tsis muaj kev puas tsuaj ib puag ncig.
• Tus nqi qis. Tau kawg, tus nqi nyob ntawm cov khoom siv raw siv hauv kev tsim cov duab los qhia. Tab sis tseem, piv rau lwm yam khoom, cardboard muaj tus nqi qis.
• Ntau yam ntawm cov khoom tso cai rau koj los ua ntau hom ntawv thawv ntawv. Cov no yog ob qho khoom plig me me thiab loj loj rau thauj rooj tog.

Nrog cov npe zoo li no, tau kawg, muaj ob peb qhov tsis zoo: opacity; tawg nyob rau hauv qhov ncaj qha ntawm noo noo. Thawj qhov teeb meem yog daws los ntawm kev ntxig cov yeeb yaj kiab polymer hauv daim ntawv ntawm qhov rais, qhov thib ob - los ntawm cov txheej txheem tshwj xeeb polymer.

Cardboard yeej ib txwm nrov vim nws cov khoom tshwj xeeb thiab tus nqi qis. Lwm qhov teeb meem yog kev txuag ntuj. Yog tias tsuas muaj kev rhuav tshem hav zoov xwb, ib puag ncig yuav raug kev txom nyem.
