Iyalahlwaiikomityi zephephaziinkonkxa zephepha ezenziwe nge-pulp yomthi zize zicutshungulwe. Kukho iintlobo ezimbini zokugquma ngaphakathi kweekomityi zephepha, enye ziikomityi zephepha ezigqunywe nge-wax kwaye enye ziikomityi zephepha ezigqunywe nge-PE.
I. Iikomityi zephepha ezifakwe iwax
Ifakwe iwaxiikomityi zephephazigqunywe ngomaleko wewax eludongeni olungaphakathi lweekomityi zephepha, ezisetyenziselwa ukwahlula ukutya okanye amanzi okusela ngaphakathi kweekomityi zephepha ukuba zingadibani ngqo neenkomityi zephepha. Kule mihla, zihlala zisetyenziswa njengeekomityi zeziselo ezibandayo.
Abanye abantu bathi “iikomityi zephepha ezifakwe iwax azinakugcina iziselo ezishushu kuba umaleko wewax ophezu komhlaba uya kunyibilika uze uxubane nokutya, nto leyo echaphazela impilo yakho”.
Enyanisweni, le ngxelo ayichanekanga. Okokuqala, kufuneka kucace ukuba i-wax coating ngaphakathi kwiikomityi zephepha eziqhelekileyo ezifanelekileyo zokulahlwa yi-wax etyiwayo, engenabungozi kwaye enganyibiliki emanzini, kwaye inani elincinci lokutya lingakhutshwa.
Kodwa iqondo lokunyibilika kwewax etyiwayo liphantsi kakhulu, kwaye liya kuzinza phakathi kwe-0-5. Kodwa nokuba kumanzi ashushu, wax etyiwayo ityiwa ngobuninzi obuncinci kwaye akukho mfuneko yokoyika ukuba awuyisebenzisi rhoqo.
Ngoko ke, ingozi efihlakeleyo ebangelwa kukusetyenziswa kweekomityi zephepha ezigqunywe ngewax (iikomityi zeziselo ezibandayo) kukuba xa umaleko wewax unyibilika kancinci kancinci, iikomityi ziya kuthamba kwaye zijike xa zidibana namanzi, kwaye ukutshiza kwamanzi kunokutsha ngokwako.

Iikomityi zephepha ze-PE ezi-2
Iikomityi zephepha ezigqunywe ngombala we-PE eludongeni olungaphakathi, zigudileyo kakhulu, zinokudlala indima yokungangeni manzi kwaye zingangeni kwioyile. I-PE yi-polyethylene, ukucubungula ukutya kuyaqinisekiswa ukuba izinto zeekhemikhali, ezaziwa ngokuba yiplastiki.
Le nto ayinavumba, ayinatyhefu, ine-wax kwaye isantya sokufunxa amanzi siphantsi, ngoko ke isetyenziswa rhoqo njengesixhobo esingangeni manzi. Iqondo layo lokunyibilika liphakathi kwe-120-140, ngelixa iqondo lokubila lamanzi liyi-100, ngoko ke ayinyibiliki emanzini kwaye iqinisekisiwe ngakumbi ukuba iyasetyenziswa.
Uninzi lweekomityi zephepha ezilahlwayo ezithengiswayo ziikomityi zephepha ezinee-layer coated (PE), oko kukuthi, ludonga lwangaphakathi lwekomityi yephepha kuphela olugqunywe, kwaye udonga lwangaphandle alugqunywanga.
Ngoko ke, akukhuthazwa ukuba usele iziselo ezibandayo, kuba xa usela iziselo ezibandayo, kulula ukwenza umngxuma eludongeni lwangaphandle lwekomityi, ukuze ikomityi ithambe lula, ubunzima bunciphe, kwaye ikomityi yephepha iguquguquke lula, nto leyo ebangela ukuba amanzi agcwale.
Enyanisweni, inani leekomityi zephepha ezifakwe iwax ezithengiswayo linciphile kakhulu. Uninzi lweekomityi zephepha esizibonayo ziikomityi zephepha ezigqunyiweyo. Ukuba ufuna ukusela iziselo ezishushu, thenga iikomityi zephepha le-copperplate ezineleya enye. Ukuba ufuna ukusela iziselo ezibandayo, kufuneka uthenge iikomityi zephepha le-copperplate ezineleya ezimbini (iikomityi zephepha le-copperplate ezineendonga zangaphandle nezangaphakathi).
Ukuba ufuna ukwazi okungakumbi malunga neemveliso zenkampani, ungacofa ikhonkco elilandelayo uze unxibelelane nathi.https://www.botongpack.com/paper-cup/
