Keeb Kwm Ntawm Daim Ntawv Khob tau dhau los ntawm plaub theem

Conical/pleated paper cups Thawj lub khob yog conical, ua los ntawm tes, glued nrog kua nplaum, yooj yim rau kev sib cais, thiab yuav tsum tau siv sai li sai tau. Tom qab ntawd, cov khob ntawv tais tau muab ntxiv rau sab phab ntsa kom muaj zog ntawm cov phab ntsa sab nrauv thiab ua haujlwm ntev ntawm cov khob ntawv, tab sis nws nyuaj dua los luam cov qauv ntawm cov folded nto, thiab cov nyhuv tsis zoo tagnrho.
Waxed ntawv khob
Xyoo 1932, thawj daim ntawv khob ob daim ntawv tuaj yeem tawm, thiab nws lub ntsej muag du tuaj yeem luam tawm nrog ntau tus qauv zoo nkauj los txhim kho kev txhawb nqa. Daim ntawv khob ciab, ntawm ib sab tuaj yeem zam cov dej haus thiab daim ntawv sib cuag ncaj qha, thiab tuaj yeem tiv thaiv cov nplaum nplaum, txhim khu kev ruaj ntseg ntawm lub khob ntawv; Ntawm qhov tod tes, lub thickness ntawm sab phab ntsa kuj nce ntxiv, kom lub zog ntawm lub khob ntawv zoo heev, yog li txo cov ntawv tsim nyog rau kev tsim cov ntawv khob kom muaj zog thiab txo cov nqi tsim khoom.
Raws li waxed ntawv khob los ua ntim rau cov dej txias, tib neeg kuj xav siv lub thawv yooj yim los tuav cov dej kub. Txawm li cas los xij, cov dej haus kub yuav yaj cov wax txheej nyob rau sab hauv ntawm lub khob ntawv, thiab lub qhov ncauj nplaum yuav raug sib cais, yog li lub khob ntawv khob tsis haum rau tuav cov dej kub.
Ncaj phab ntsa ob khob
Txhawm rau nthuav dav cov ntawv thov ntawm cov ntawv khob, hauv xyoo 1940, cov phab ntsa ncaj nraim ob txheej ntawv khob tau qhia rau lub khw. Lub khob ntawv no tsis yog yooj yim nqa xwb, tab sis kuj tuaj yeem siv los tuav cov dej kub. Tom qab ntawd, cov tuam txhab tsim cov khob no nrog cov latex los npog cov "dawb tsis hnov ​​​​tsw" ntawm daim ntawv thiab ntxiv dag zog rau cov khoom pov thawj ntawm cov khob ntawv.

Coated yas ntawv khob
Qee lub tuam txhab ua zaub mov tau pib siv cov polyethylene rau cov duab los qhia kom muaj kev thaiv thiab nruj ntawm cov ntawv ntim. Vim hais tias lub melting point ntawm polyethylene yog ntau dua li ntawm cov quav ciab, lub khob tshiab haus khob coated nrog cov khoom no yuav siv tau los tuav cov dej kub, uas yuav daws tau qhov teeb meem uas cov khoom zoo cuam tshuam los ntawm melting ntawm cov khoom txheej. Nyob rau tib lub sijhawm, cov txheej txheej polyethylene yog smoother dua li cov ntaub ntawv qub, txhim kho cov tsos ntawm daim ntawv khob. Tsis tas li ntawd, cov txheej txheem txheej txheem kuj tseem pheej yig dua thiab sai dua li txheej txheej latex.
