Ungasarudza sei chubhu yepurasitiki yemhando yepamusoro yekushongedza?

Chubhu yepurasitiki yekushongedza, kurongedza uku kuri nyore uye kwakachipa kune zvakawanda zvinoshandiswa mumakemikari ezuva nezuva, uye kwakakurumbira zvikuru. Kwakanaka kwazvo chubhu yepurasitiki yekushongedzahaingogone chete kuchengetedza zviri mukati, asiwo kuvandudza huwandu hwechigadzirwa, kuitira kuti iwane vatengi vakawanda vemabhizinesi emakemikari ezuva nezuva. Saka, kumabhizinesi emakemikari ezuva nezuva, ungasarudza sei machubhu epurasitiki emhando yepamusoro anoenderana nezvigadzirwa zvavo? Pazasi tichataura kubva pane zvakati wandei zvakakosha.

Kuomarara kwezvinhu: Makambani emakemikari ezuva nezuva ane zvinodiwa zvakasiyana zve chubhu yepurasitiki yekushongedzakuomarara, saka ungawana sei kuomarara kwaunoda? Polyethylene inowanzoshandiswa mu chubhu yepurasitiki yekushongedzas inonyanya kuve polyethylene ine density yakaderera, polyethylene ine density yakakura, uye polyethylene ine linear low-density. Kuomarara kwepolyethylene ine density yakakura kuri nani pane kwepolyethylene ine density yakaderera, saka kuomarara kunodiwa kunogona kuwanikwa nekugadzirisa chiyero chepolyethylene ine density yakakura/polyethylene ine density yakaderera.

Kuramba kwemakemikari kwezvinhu: polyethylene ine huwandu hwakanyanya hwemakemikari inorambira zviri nani pane polyethylene ine huwandu hwakaderera hwemakemikari.

Kukwanisa kwemamiriro ekunze kwezvinhu: Kudzora mashandiro enguva pfupi kana refu echinhu chacho chubhu yepurasitiki yekushongedza, unofanira kufunga nezve: chitarisiko, kuramba kudzvanywa/kudonha, simba rekuvharwa, kuramba kupwanyika kwekumanikidzwa kwezvakatipoteredza (ESCR value), kunhuhwirira uye kurasikirwa nezvinhu zvinoshanda.

Kusarudzwa kweMasterbatch: masterbatch ine basa rakakosha mu chubhu yepurasitiki yekushongedzakudzora mhando. Saka, pakusarudza masterbatch, kambani yemushandisi inofanira kufunga kana ine kupararira kwakanaka, kusefa uye kugadzikana kwekupisa, kuramba mamiriro ekunze uye kuramba chigadzirwa. Pakati pazvo, kuramba chigadzirwa che masterbatch kwakakosha zvikuru pakushandisa chubhu yepurasitiki yekushongedza, kana masterbatch isingaenderane nechigadzirwa chakaiswa, ruvara rwemasterbatch ruchaenda kuchigadzirwa, uye mhedzisiro yacho yakakomba zvikuru. Saka, mabhizinesi emakemikari ezuva nezuva anofanira kuyedza kugadzikana kwezvigadzirwa zvitsva uye chubhu yepurasitiki yekushongedzas (ita bvunzo dzinokurumidza pasi pemamiriro akatarwa).

Mhando dzemafuta anopenya uye hunhu hwawo: mafuta anopenya anoshandiswa mu chubhu yepurasitiki yekushongedzaimhando yeUV ye ultraviolet uye mhando yekuomesa inopisa, iyo inogona kukamurwa kuita pamusoro wakajeka uye pamusoro pemhute kubva pakuonekwa. Oiri yeGloss haingogone kungopa mhedzisiro yakanaka yekuona, asiwo inoita basa rekudzivirira zviri mukati, uye ine mhedzisiro yakati paokisijeni, utsi hwemvura, uye chipingamupinyi chekunhuhwirira. Kazhinji, mhando yeGloss yekuomesa inopisa ine kunamira kwakanaka kune inotevera bronzing uye screen printing, uye ultraviolet UV gloss ine gloss iri nani. Makambani emakemikari ezuva nezuva anogona kusarudza mafuta egloss akakodzera zvichienderana nehunhu hwezvigadzirwa zvavo. Pamusoro pezvo, oiri yegloss yakaporeswa inofanira kunge yakanamatira zvakanaka, pamusoro wakatsetseka pasina maburi, kuramba kupeta, kuramba kupfeka, kuramba ngura, uye kusachinja ruvara panguva yekuchengetera.

Zvinotendwa kuti kubva pane zvataurwa pamusoro apa, makambani mazhinji emakemikari ezuva nezuva anofanira kukwanisa kusarudza emhando yepamusoro chubhu yepurasitiki yekushongedzazvigadzirwa zvekurongedza.
