Kuv ntseeg tias peb tsis paub txog cov khob ntawv, peb yuav koom nrog hauv peb lub neej txhua hnub, xws li: khob ntawv pov tseg, khob ntawv khob thiab lwm lub khob ntawv, cov hauv qab no yuav muab rau koj sau cov keeb kwm kev loj hlob ntawm cov khob ntawv;
Txoj kev loj hlob ntawm daim ntawv khob keeb kwm tau dhau los ntawm plaub theem:
1.Cone ntawv khob
Conical / folding paper cups Tus thawj daim ntawv khob yog conical, ua los ntawm tes, sib txuas los ntawm cov kua nplaum, sib cais yooj yim dua, thiab yuav tsum tau siv sai li sai tau. Tom qab ntawd, cov folding ntawv khob tau muab tais rau ntawm phab ntsa kom muaj zog ntawm sab phab ntsa thiab lub zog ntawm cov khob ntawv, tab sis nws nyuaj rau luam cov qauv ntawm cov folding qhov chaw, thiab cov nyhuv tsis zoo.
2.Coat ciab ntawv khob
Nyob rau hauv 1932, tsuas yog ob daim ntawm cov ntaub ntawv khob tau tshwm sim, nws lub ntsej muag du tuaj yeem luam tawm nrog ntau tus qauv zoo nkauj, txhawm rau txhim kho kev txhawb nqa. Cov quav ciab, ntawm ib sab, tuaj yeem zam kev sib cuag ncaj qha nrog daim ntawv, thiab tuaj yeem tiv thaiv cov nplaum ntawm cov kua nplaum thiab txhim kho lub zog ntawm lub khob ntawv; ntawm qhov tod tes, nws kuj ua rau lub thickness ntawm sab phab ntsa kom muaj zog ntawm daim ntawv khob, yog li txo cov ntawv tsim nyog rau kev tsim cov ntawv khob kom muaj zog thiab txo cov nqi tsim khoom. Raws li wax ntawv khob ua ntim rau cov dej txias, nws tseem cia siab tias lub nkoj yooj yim tuaj yeem nqa cov dej kub. Txawm li cas los xij, cov dej qab zib kub yuav yaj cov wax txheej nyob rau sab hauv ntawm lub khob ntawv, thiab lub qhov ncauj nplaum yuav raug muab cais tawm, yog li lub khob ntawv siv quav ciab tsis haum rau nqa cov dej kub.
3. Ncaj phab ntsa ob txheej khob
Txhawm rau nthuav dav daim ntawv thov ntau yam ntawm cov ntawv khob, ncaj phab ntsa ob lub khob ntawv tau qhia rau lub khw hauv xyoo 1940. Cov khob ntawv tsis yog yooj yim nqa xwb, tab sis kuj tseem siv tau los tuav cov dej kub. Tom qab ntawd, cov chaw tsim khoom tau coated cov latex ntawm cov khob no los npog "cov duab los qhia" ntawm cov ntaub ntawv, thiab ntxiv dag zog rau cov dej tsis kam ntawm lub khob ntawv. Ib txheej wax khob kho nrog latex txheej yog dav siv nyob rau hauv tus kheej-kev pab cuam vending machine los tuav kas fes kub.
4.Siv lub khob ntawv yas
Qee lub tuam txhab khoom noj tau pib muab polyethylene rau ntawm daim duab los qhia kom muaj kev thaiv thiab kev sib khi ntawm cov ntawv ntim. Txij li thaum lub melting point ntawm polyethylene yog ho siab dua li ntawm wax, hom tshiab ntawm cov dej haus ntawv khob coated nrog cov ntaub ntawv no yuav ua tau zoo tagnrho siv los nqa cov dej qab zib, uas daws qhov teeb meem ntawm cov khoom zoo cuam tshuam los ntawm melting ntawm cov khoom txheej. Nyob rau tib lub sijhawm, cov xim pleev xim polyethylene yog smoother dua li cov xim qub qub, txhim kho cov tsos ntawm daim ntawv khob. Tsis tas li ntawd, nws cov cuab yeej ua haujlwm tseem pheej yig dua thiab sai dua li kev siv cov txheej txheem latex.
