Mokhoa oa ho khetha lipeipi tsa polasetiki tsa boleng bo holimo

Liphaephe, thepa e bonolo le e theko e tlase ea ho paka, li sebelisoa haholo indastering ea lik'hemik'hale ea letsatsi le letsatsi 'me li tumme haholo. Phaephe ea boleng bo holimo ha e sireletse feela litaba empa e boetse e ntlafatsa boemo ba sehlahisoa, kahoo e thusa likhoebo tsa lik'hemik'hale tsa letsatsi le letsatsi ho hapa bareki ba bangata. Kahoo, bakeng sa likhoebo tsa lik'hemik'hale tsa letsatsi le letsatsi, u ka khetha liphaephe tsa polasetiki tsa boleng bo holimo tse loketseng lihlahisoa tsa tsona joang? Ka tlase, re tla hlahisa ho tsoa lintlheng tse 'maloa tsa bohlokoa.

Ho tiea ha thepa: Litlhoko tsa ho tiea ha lipeipi lia fapana ho latela lik'hamphani tsa lik'hemik'hale tsa letsatsi le letsatsi. Joale, ho tiea ho lakatsehang ho ka finyelloa joang? Polyethylene e sebelisoang hangata lipeiping e kenyelletsa polyethylene e nang le boima bo tlase, polyethylene e nang le boima bo phahameng le polyethylene e nang le boima bo tlase bo otlolohileng.

Ho hanyetsa dikhemikhale tsa thepa: Polyethylene e nang le sekgahla se phahameng e na le sekgahla se betere sa dikhemikhale ho feta polyethylene e nang le sekgahla se tlase.

Ho hanyetsa maemo a leholimo ha thepa: Ho laola ts'ebetso ea nako e khuts'oane kapa ea nako e telele ea lipeipi, lintlha tse kang ponahalo, ho hanyetsa khatello/ho theoha ha metsi, matla a ho koala, ho hanyetsa khatello ea tikoloho (boleng ba ESCR), monko o monate le tahlehelo ea metsoako e sebetsang li hloka ho nahanoa.

Khetho ea li-masterbatches tsa mebala: Li-masterbatches tsa mebala li bapala karolo ea bohlokoa taolong ea boleng ba li-tube. Ka hona, ha li khetha li-masterbatches tsa mebala, likhoebo tsa basebelisi li lokela ho nahana hore na li na le ho qhalana ho hotle, ho sefa le botsitso ba mocheso, ho hanyetsa boemo ba leholimo le ho hanyetsa lihlahisoa. Likhamphani tsa lik'hemik'hale tsa letsatsi le letsatsi li lokela ho leka botsitso ba lihlahisoa le li-tube tse ncha (li etse liteko tse potlakileng tlas'a maemo a boletsoeng).

Mefuta ea varnish le litšobotsi tsa eona tse fapaneng: Varnish e sebelisoang bakeng sa lipeipi e arotsoe ka mofuta oa ultraviolet (UV) le mofuta oa omisitsoeng ke mocheso. Mabapi le ponahalo, e ka aroloa ka ho eketsehileng ka ho benya le ho se benye. Varnish ha e fane feela ka phello e ntle ea pono, empa hape e sireletsa litaba 'me e na le phello e itseng ea ho thibela oksijene, mouoane oa metsi le monko o monate.

Litlhoko tsa 'mele oa phaephe/hlooho ea phaephe: 1. Bokaholimo ba 'mele oa phaephe bo lokela ho ba bo boreleli le bo hloekileng, bo se nang mela, maqeba, maqeba le ho sotha ha sebopeho. 'Mele oa phaephe o lokela ho otloloha 'me o se ke oa kobeha. Botenya ba lebota la phaephe bo lokela ho lekana. Mamello ea boholo ba botenya ba lebota la phaephe, bolelele ba phaephe le bophara kaofela li lokela ho ba ka har'a moeli o boletsoeng.

Litlhoko tsa ho hatisa: Khatiso ea OFFSET hangata e sebelisetsoa ho sebetsana le liphaephe, 'me boholo ba enke e sebelisoang e omisitsoe ka UV. Hangata e hloka ho khomarela ho matla le ho hanyetsa 'mala oa enke. 'Mala oa ho hatisa o lokela ho ba ka har'a sebaka se boletsoeng sa botebo, boemo ba khatiso e fetang bo lokela ho nepahala, ho kheloha ho lokela ho ba ka har'a 0.2mm, 'me mongolo o lokela ho ba o felletseng le o hlakileng.

Litlhoko tsa likhetla tsa polasetiki: Likhetla tsa polasetiki hangata li entsoe ka ente ho tsoa ho polypropylene (PP). Likhetla tsa polasetiki tsa boleng bo holimo ha lia lokela ho ba le matšoao a totobetseng a ho fokotseha kapa ho benya, mola oa ho koala hlobo o lokela ho ba boreleli, litekanyo li nepahetse, 'me li lokela ho lumellana hantle le hlooho ea phaephe. ​​Nakong ea tšebeliso e tloaelehileng, ha lia lokela ho baka tšenyo ea sebopeho joalo ka ho robeha kapa mapetso. Mohlala, ha matla a ho bula a le sebakeng se loketseng, sekoahelo se lokela ho khona ho menwa ka makhetlo a fetang 300 ntle le ho robeha.

Ho lumeloa hore ka ho qala ka lintlha tse boletsoeng ka holimo, boholo ba likhoebo tsa lik'hemik'hale tsa letsatsi le letsatsi li lokela ho khona ho khetha lihlahisoa tsa boleng bo holimo tsa ho paka lipeipi.
