Siv taudaim ntawv khobyog cov thawv ntawv ua los ntawm cov ntoo pulp thiab tom qab ntawd ua tiav.Muaj ob hom txheej txheej sab hauv ntawm lub khob ntawv, ib qho yog wax coated ntawv khob thiab lwm yam yog PE coated ntawv khob.
I. Waxed paper cups
Waxeddaim ntawv khobyog coated nrog ib txheej ntawm cov quav ciab rau ntawm phab ntsa sab hauv ntawm lub khob ntawv, uas yog siv los cais cov zaub mov lossis dej haus hauv cov khob ntawv los ntawm kev sib cuag ncaj qha nrog cov thawv ntawv.Niaj hnub no, lawv feem ntau yog siv los ua khob dej txias.
Qee tus neeg hais tias "cov ntawv khob ntim dej tsis tuaj yeem tuav dej kub vim tias cov ntaub nplaum rau ntawm qhov chaw yuav yaj thiab sib xyaw nrog zaub mov, cuam tshuam rau koj kev noj qab haus huv".
Qhov tseeb, nqe lus no tsis raug.Ua ntej ntawm tag nrho cov, nws yuav tsum paub meej tias cov wax txheej sab hauv lub khob ntim cov ntawv pov tseg tsis tu ncua yog cov khoom siv uas siv tau, uas tsis muaj tshuaj lom thiab tsis muaj kuab lom hauv dej, thiab cov zaub mov me me tuaj yeem tso tawm.
Tab sis lub melting point ntawm edible ciab yog heev tsawg, thiab yuav stabilized ntawm 0-5.Tab sis txawm tias muaj dej kub, cov khoom noj khoom haus tau noj hauv qhov me me thiab tsis tas yuav ntshai yog tias koj tsis siv nws tsis tu ncua.
Yog li ntawd, qhov kev phom sij zais cia los ntawm kev siv cov khob ntim cov ntaub ntawv (cov khob dej txias) yog tias thaum cov wax txheej maj mam yaj, cov khob yuav muag thiab deform thaum lawv los rau hauv dej, thiab cov dej txaws tuaj yeem hlawv. ntawm nws tus kheej.

2 PE ntawv khob
Coated (PE) daim ntawv khob hauv lub khob ntawv npog nrog txheej txheej PE ntawm sab hauv phab ntsa, du heev, tuaj yeem ua lub luag haujlwm ntawm cov dej tsis zoo thiab cov roj pov thawj.PE yog polyethylene, kev ua zaub mov yog paub tseeb tias cov tshuaj lom neeg, tseem hu ua yas.
Cov khoom no tsis muaj ntxhiab tsw, tsis muaj tshuaj lom, waxy thiab muaj qhov nqus dej tsawg, yog li nws feem ntau siv los ua cov khoom siv dej tsis zoo.Nws cov ntsiab lus melting yog nyob nruab nrab ntawm 120-140, thaum lub boiling point ntawm dej yog 100, yog li nws tsis yaj nyob rau hauv dej thiab paub tseeb tias yuav siv tau.
Feem ntau ntawm cov khob ntawv pov tseg ntawm kev ua lag luam yog ib txheej txheej coated (PE) daim ntawv khob, piv txwv li, tsuas yog cov phab ntsa sab hauv ntawm lub khob ntawv yog coated, thiab cov phab ntsa sab nrauv tsis coated.
Yog li ntawd, nws tsis pom zoo kom haus cov dej txias, vim tias thaum koj haus cov dej txias, nws yog ib qho yooj yim los tsim condensation rau sab nrauv phab ntsa ntawm lub khob, kom lub khob yog yooj yim los ua mos, lub hardness txo, thiab daim ntawv khob. yog ib qho yooj yim deformed, ua rau dej ntws.
Qhov tseeb, tus naj npawb ntawm waxed ntawv khob ntawm kev ua lag luam tau txo qis me ntsis.Feem ntau ntawm cov khob ntawv peb pom yog coated ntawv khob.Yog tias koj xav haus dej haus kub, yuav ib txheej txheej tooj liab khob ntawv khob.Yog tias koj xav haus dej txias, koj yuav tsum yuav ob-txheej copperplate ntawv khob (copperplate ntawv khob nrog ob sab nrauv thiab sab hauv phab ntsa).
Yog tias koj xav paub ntau ntxiv txog lub tuam txhab cov khoom, koj tuaj yeem nyem qhov txuas hauv qab no thiab tiv tauj peb.https://www.botongpack.com/paper-cup/
