Iyalahlwaiikomityi zephephazizikhongozeli zephepha ezenziwe ngomthi womthi emva koko zicocwe.Kukho iindidi ezimbini zokwaleka ngaphakathi kwiikomityi zephepha, enye yeyeekomityi zephepha eziqatywe wax kwaye enye ziikomityi zephepha eziqatywe nge-PE.
I. Iikomityi zephepha eziweksiweyo
Iwaxediikomityi zephephazigqunywe ngomaleko wewax kudonga lwangaphakathi lweekomityi zephepha, ezisetyenziselwa ukwahlula ukutya okanye amanzi okusela ngaphakathi kweekomityi zephepha ekudibaneni ngqo nezikhongozeli zephepha.Namhlanje, zisetyenziswa ngokubanzi njengekomityi yesiselo esibandayo.
Abanye abantu bathi “iikomityi zephepha eline-wax azikwazi kubamba iziselo ezishushu kuba umaleko wewax ongaphezulu uya kunyibilika kwaye uxube nokutya, okuchaphazela impilo yakho”.
Enyanisweni, le ngxelo ayichanekanga.Okokuqala, kufuneka kucace ukuba i-wax yokugqoka ngaphakathi kweekomityi zephepha ezisemgangathweni eziqhelekileyo ezilahlwayo ziyi-wax edliwayo, engeyiyo inetyhefu kwaye inganyibiliki emanzini, kunye nokutya okuncinci kunokukhutshwa.
Kodwa indawo yokunyibilika yewax etyiwayo iphantsi ngokwenene, kwaye iya kuzinziswa phakathi kwe-0-5.Kodwa nangamanzi ashushu, iwax etyiwayo igalelwa ngamancinci kwaye akukho mfuneko yokoyika ukuba awuyisebenzisi rhoqo.
Ke ngoko, ingozi efihlakeleyo ebangelwa kukusetyenziswa kweekomityi zephepha eziqatywe ngewax (iikomityi zesiselo esibandayo) kukuba xa umaleko wewax unyibilika ngokuthe ngcembe, iikomityi ziya kuthamba kwaye zikhubazeke xa zidibana namanzi, kwaye ukuchaphaza kwamanzi kunokutshisa. ngokwayo.

Iikomityi zephepha ezi-2 ze-PE
Iikomityi zephepha ezifakwe (PE) kwiikomityi zephepha ezigqunywe ngoluhlu lwe-PE eludongeni lwangaphakathi, olugudileyo kakhulu, lunokudlala indima yokungangeni kwamanzi kunye neoli.I-PE yi-polyethylene, ukulungiswa kokutya kuqinisekiswa ukuba izinto zekhemikhali, ezikwaziwa njengeplastiki.
Lo mbandela awunavumba, awunayo ityhefu, i-waxy kwaye inezinga eliphantsi lokufunxa amanzi, ngoko ke lihlala lisetyenziswa njengento engenamanzi.Indawo yayo yokuncibilika iphakathi kwe-120-140, ngelixa indawo yokubilisa yamanzi i-100, ngoko ayinyibiliki emanzini kwaye iqinisekisiwe ngakumbi ukuba isetyenziswe.
Uninzi lweekomityi zephepha ezilahlayo kwiimarike ziyi-single-layer coated (PE) iikomityi zephepha, oko kukuthi, kuphela udonga lwangaphakathi lwekomityi yephepha lugqunywe, kwaye udonga lwangaphandle alufakwanga.
Ngoko ke, akukhuthazwa ukuba uthathe iziselo ezibandayo, kuba xa uthatha iziselo ezibandayo, kulula ukwenza i-condensation eludongeni olungaphandle lwendebe, ukuze kube lula ukuba ikomityi ibe yinto ethambileyo, ubunzima buyancipha, kunye nekomityi yephepha. kulula ukukhubazeka, okukhokelela ekuphuphumeni kwamanzi.
Ngapha koko, inani leekomityi zephepha elenziwe wax kwimarike lehlile kancinci.Uninzi lweekomityi zephepha esizibonayo ziikomityi zephepha eziqatywe.Ukuba ufuna ukusela iziselo ezishushu, thenga iikomityi zephepha lecwecwe elilodwa.Ukuba ufuna ukusela iziselo ezibandayo, kufuneka uthenge iikomityi zephepha le-copperplate eziphindwe kabini (iikomityi zephepha le-copperplate kunye neendonga zangaphandle nangaphakathi).
Ukuba ufuna ukwazi ngakumbi malunga neemveliso zenkampani, ungacofa ikhonkco elilandelayo kwaye uqhagamshelane nathi.https://www.botongpack.com/paper-cup/
