Kwihlabathi lanamhlanje elikhawulezayo lezothutho kunye nothungelwano lokubonelela, kubalulekile ukuba iimveliso zithuthwe ngokukhuselekileyo nangokufanelekileyo. Kwaye emva koku, kukho "umlindi ongabonakaliyo" ongaziwayo - ifilimu eyoluliweyo. Le filimu yeplastiki ebonakala ilula, eneempawu zayo ezintle kunye noluhlu olubanzi lwezicelo, ibe yinxalenye ebalulekileyo yokupakisha kwanamhlanje.
1. Ifilimu yolula: ayisiyo "ifilimu yokuncamathela" kuphela
Ifilimu yokusolula, njengoko igama layo lisitsho, yifilimu yeplastiki eneempawu zokutsala eziphezulu. Ihlala yenziwe nge-linear low density polyethylene (LLDPE) kwaye kongezwa ezinye izongezo ukuphucula iimpawu zayo. Ngokungafaniyo neefilimu zokukhusela eziqhelekileyo, iifilimu zokusolula zinamandla aphezulu, ziqinile, kwaye ziyamelana nokukrala, kwaye zinokumelana nemingeni eyahlukeneyo ngexesha lokuthuthwa.
2. "Izixhobo Ezidumileyo zaseTshayina"
Uluhlu lweendlela zokusetyenziswa kwefilimu ethambileyo lubanzi kakhulu kwaye lugubungela phantse zonke iimeko apho imveliso kufuneka ilungiswe kwaye ikhuselwe:
ukupakishwa kwetreyi: Le yeyona ndlela ixhaphakileyo yokusebenzisa ifilimu yokunwebeka. Emva kokufaka iimpahla kwipalethi, ukuzisonga ngefilimu yokunwebeka kunokuthintela iimpahla ukuba zingachitheki kwaye zidilike, kwaye kudlala indima yokuthintela uthuli kunye nokufuma.
Ukupakishwa kweebhokisi: Kwiibhokisi ezifuna ukhuseleko olongezelelweyo, ifilimu yokusolula ingasetyenziselwa ukusonga yonke iphakheji, yonyusa amandla ebhokisi kwaye ithintele umonakalo.
Ukupakishwa kwemithwalo emikhulu: Kwiimpahla ezinkulu nezinemilo engaqhelekanga, ezifana nefenitshala, izixhobo zoomatshini, njl.njl., ifilimu ethambileyo ingasetyenziselwa ukuyijika nokuyilungisa ukuze kube lula ukuthuthwa nokugcinwa.
Ezinye iindlela zokusetyenziswa: Ifilimu eyoluliweyo ingasetyenziswa ekubopheni nasekulungiseni, ekukhuseleni umphezulu, ekugqumeni ukhuseleko lothuli nakwezinye iimeko.
3. "Imfihlo" yokukhetha ifilimu yokuzolula
Kukho iintlobo ezininzi zeefilimu zokunweba ezithengiswayo, kwaye ezi zinto zilandelayo kufuneka ziqwalaselwe xa kukhethwa ifilimu yokunweba efanelekileyo:
Ubukhulu: Okukhona ubukhulu bukhulu, kokukhona amandla efilimu yokunwebeka emancinci, kodwa ixabiso liphezulu. Ubukhulu obufanelekileyo kufuneka bukhethwe ngokwesisindo somthwalo kunye nendawo yokuthutha.
Ubunzima: Ubunzima buxhomekeke kubungakanani bepalethi okanye umthwalo. Ukukhetha ububanzi obufanelekileyo kunokuphucula ukusebenza kakuhle kokupakisha.
Izinga lokunwebeka ngaphambi kokwelula: Okukhona izinga lokunwebeka ngaphambi kokwelula liphezulu, kokukhona izinga lokusetyenziswa kwefilimu yokunwebeka liphezulu, kodwa kokukhona kunzima ukuyisebenzisa xa kupakishwa ngesandla.
Umbala: Ifilimu ecacileyo yokunwebeka yenza kube lula ukuyijonga impahla, ngelixa ifilimu emnyama okanye eminye imibala yokunwebeka inokusebenza njengesikhuselo ekukhanyeni nakwimitha ye-UV.
4. "Iingcebiso" zokusebenzisa ifilimu eyoluliweyo
* Xa usebenzisa ifilimu yokutsala, kufuneka kugcinwe uxinzelelo olufanelekileyo. Ukuba ikhululekile kakhulu ayinakusebenza njengesiphumo esisisigxina, kwaye ukuba iqine kakhulu kunokonakalisa impahla.
* Xa kupakishwa ngesandla, indlela yokubamba "i-spiral" okanye "yeentyatyambo" ingasetyenziswa ukuqinisekisa ukuba onke amacala empahla asongiwe ngokulinganayo.
* Ukusetyenziswa komatshini wokupakisha wefilimu eyoluliweyo kunokuphucula kakhulu ukusebenza kakuhle kokupakisha nokuqinisekisa ukuhambelana komgangatho wokupakisha.
V. Ikamva lefilimu eyoluliweyo: inobuhlobo nokusingqongileyo kwaye ikrelekrele ngakumbi
Ngokuphuculwa kolwazi ngokusingqongileyo, ifilimu yokunwebeka ebolayo nephinda isetyenziswe iya kuba yindlela yophuhliso lwexesha elizayo. Ukongeza, iimembrane ezikrelekrele zokunwebeka ziya kuvela, ezifana neemembrane zokunwebeka ezinokujonga imeko yemithwalo ngexesha langempela, zibonelela ngokhuseleko olupheleleyo lwezothutho.
Lilonke, ifilimu eyoluliweyo idlala indima ebalulekileyo kwimpahla yanamhlanje njengesixhobo sokupakisha esisebenzayo nesingabizi kakhulu. Kukholelwa ukuba ngokuqhubeka kweteknoloji, ifilimu eyoluliweyo iya kuba namandla kwaye ibe krelekrele ngakumbi, nto leyo eza kusenza sibe lula ngakumbi kwimveliso yethu nakubomi bethu.
