Txhua Yam Txog Lub Hnab Ntawv: Nws Keeb Kwm, Inventors thiab Hom Niaj Hnub No
Lub hnab ntawv loj xim av muaj keeb kwm ntev, nthuav dav.
Cov hnab ntawv xim av tau dhau los ua qhov khoom siv hauv peb lub neej txhua hnub: peb siv lawv nqa khoom noj hauv tsev, nqa peb lub khw muag khoom, thiab ntim peb cov menyuam noj su.Cov khw muag khoom siv lawv ua ib daim ntaub dawb rau lawv cov khoom ntim khoom lag luam.Creative tricks-lossis-kho-kho txawm hnav lawv li qhov ncauj qhov ntswg rau Halloween.Nws yooj yim kom tsis nco qab tias ib tug neeg, ntev dhau los, yuav tsum tau tsim lawv!
Cov Innovators uas muab peb lub hnab ntawv
Tau ntau pua xyoo, cov hnab ua los ntawm jute, canvas, thiab burlap yog thawj txoj hauv kev tuav thiab txav khoom thoob plaws tebchaws Askiv.Cov txiaj ntsig tseem ceeb ntawm cov ntaub ntawv no yog lawv qhov ruaj khov, ruaj khov, tab sis lawv cov khoom pov thawj ob qho tib si siv sijhawm thiab kim.Daim ntawv, ntawm qhov tod tes, tuaj yeem tsim tau ntawm tus nqi qis dua, thiab tsis ntev los no tau dhau los ua cov khoom tseem ceeb rau cov hnab nqa tau raws li kev lag luam.
Txij li thaum nws tau nthuav tawm hauv xyoo 1800s, lub hnab ntawv tau dhau los ua ntau yam kev hloov kho dua tshiab ua tsaug rau ob peb tus neeg txawj ntse tshiab.Xyoo 1852, Francis Wolle tau tsim thawj lub tshuab los tsim cov hnab ntawv loj.Thaum Wolle lub hnab ntawv zoo nkaus li zoo li lub hnab ntawv loj dua li lub khw muag khoom noj uas peb paub niaj hnub no (thiab yog li tsuas yog siv los tote cov khoom me me thiab cov ntaub ntawv), nws lub tshuab yog lub hauv paus rau kev siv cov ntawv ntim khoom.
Cov kauj ruam tseem ceeb tom ntej hauv kev tsim lub hnab ntawv yog los ntawm Margaret Knight, tus neeg tsim khoom muaj txiaj ntsig tom qab ntawd ua haujlwm rau Columbia Paper Bag Company.Nyob ntawd, nws pom tau tias lub hnab ntim hauv qab, tsis yog Wolle lub hnab ntawv tsim, yuav siv tau ntau dua thiab siv tau zoo.Nws tsim nws lub hnab ntawv ua tshuab nyob rau hauv ib lub khw muag khoom, paving txoj kev rau kev lag luam dav siv cov hnab ntawv.Nws lub tshuab ua pov thawj muaj txiaj ntsig zoo uas nws yuav mus nrhiav nws lub tuam txhab, Eastern Paper Bag Company.Thaum koj nqa khoom noj hauv tsev los ntawm lub tsev loj lossis yuav khoom tshiab los ntawm lub khw muag khoom, koj txaus siab rau cov txiv hmab txiv ntoo ntawm Knight txoj haujlwm.
Cov hnab ntim hauv qab no tseem ploj lawm ib qho classic ntawm lub hnab ntawv uas peb paub thiab nyiam niaj hnub no: pleated sab.Peb tuaj yeem ua tsaug Charles Stillwell rau qhov sib ntxiv no, uas ua rau lub hnab ntim tau yooj yim thiab yog li khaws cia yooj yim dua.Ib tug kws kho tshuab los ntawm kev lag luam, Stillwell tus tsim yog feem ntau hu ua SOS hnab, los yog "tus kheej-qhib sacks."
Tab sis tos - muaj ntau ntxiv!Xyoo 1918, ob lub khw muag khoom hauv St. Paul los ntawm cov npe ntawm Lydia thiab Walter Deubener tuaj nrog ib lub tswv yim rau kev txhim kho rau tus qauv qub.Los ntawm kev xuas nrig ntaus rau hauv ob sab ntawm lub hnab ntawv thiab txuas ib txoj hlua uas muab ob npaug rau kev tuav thiab hauv qab, Deubeners pom tias cov neeg siv khoom tuaj yeem nqa yuav luag 20 phaus zaub mov hauv txhua lub hnab.Thaum lub sij hawm thaum cov nyiaj ntsuab-thiab-nqa khoom noj tau hloov cov khoom xa tuaj hauv tsev, qhov no tau ua pov thawj qhov kev tsim kho tshiab tseem ceeb.
Yog li cov ntaub ntawv dab tsi yog lub hnab ntawv tiag tiag?Cov khoom siv nrov tshaj plaws rau cov hnab ntawv yog Kraft daim ntawv, uas yog tsim los ntawm cov ntoo chips.Keeb xeeb xeeb los ntawm German chemist los ntawm lub npe ntawm Carl F. Dahl nyob rau hauv 1879, cov txheej txheem rau kev tsim Kraft daim ntawv yog raws li nram no: cov ntoo chips raug mob heev kub, uas lov lawv mus rau hauv cov ntaub so ntswg thiab byproducts.Tom qab ntawd lub pulp raug tshuaj xyuas, ntxuav, thiab tshuaj dawb, noj nws daim ntawv kawg raws li daim ntawv xim av peb txhua tus paub.Cov txheej txheem pulping no ua rau Kraft daim ntawv muaj zog tshwj xeeb (li no nws lub npe, uas yog German rau "lub zog"), thiab yog li zoo tagnrho rau kev nqa hnyav.
Tau kawg, muaj ntau dua los xaiv lub hnab ntawv zoo tshaj li cov khoom siv xwb.Tshwj xeeb yog tias koj xav tau nqa cov khoom loj lossis hnyav, muaj ob peb lwm yam zoo los xav txog thaum xaiv cov khoom uas yuav pab tau koj cov kev xav tau zoo tshaj:
Paper Basis Nyhav
Kuj hu ua grammage, daim ntawv hauv qab hnyav yog qhov ntsuas ntawm cov ntawv tuab npaum li cas, hauv phaus, ntsig txog cov ntawv ntawm 500. Qhov ntau dua, cov ntawv tuab thiab hnyav dua.
