Pepa rePLA
PLA imhando yeAliphatic Polyester ine chimiro chemutsara. PLA inogona kushandiswa mumapakeji akaomarara emichero, miriwo, mazai, chikafu chakabikwa uye chikafu chakagochwa, inogonawo kushandiswa pakurongedza masangweji, mabhisikiti nemamwe mapakeji akaita semaruva matsva.
Tsananguro yeChigadzirwa
Polylactic acid (PLA) inogona kuoreswa zvachose kuita carbon dioxide nemvura kana yaraswa. Inodzivirira mvura zvakanaka, ine hunhu hwemakanika, inoenderana nehupenyu, inogona kutorwa nezvisikwa, uye haina kusvibiswa kwezvakatipoteredza. Panguva imwe chete, PLA ine hunhu hwakanaka hwemakanika. Ine simba guru, inochinjika zvakanaka uye kugadzikana kwekupisa, inokwanisa kushandiswa, haichinji ruvara, inopinda zvakanaka muokisijeni nemupfudze wemvura, uye yakajeka, inodzivirira kuvhuvhuta, inorwisa mabhakitiriya, hupenyu hwebasa imakore 2-3.
Chinonyanya kukosha pakurongedza zvinhu ndechekupinda kwemhepo, uye nzvimbo yekushandisa zvinhu izvi mukupakata inogona kutsanangurwa zvichienderana nekusiyana kwekupinda kwemhepo kwezvinhu. Zvimwe zvinhu zvekurongedza zvinoda kupinda kweokisijeni kuti zvipe okisijeni yakakwana kuchigadzirwa; zvimwe zvinhu zvekurongedza zvinoda chipingamupinyi kuokisijeni maererano nezvinhu, zvakaita sekurongedza zvinwiwa, izvo zvinoda zvinhu zvinogona kudzivirira okisijeni kupinda mupakeji kuti zvidzivise kukura kwechinhu. PLA ine chipingamupinyi chegasi, chipingamupinyi chemvura, kujeka uye kudhindwa kwakanaka.
PLA ine kujeka kwakanaka uye inopenya, uye mashandiro ayo akanaka kwazvo akafanana ne cellophane nePET, izvo zvisingawanikwe mune mamwe mapurasitiki anogona kuora. Kujeka uye kupenya kwePLA kwakapetwa kaviri kusvika katatu kupfuura firimu rePP rakajairika uye kagumi kupfuura LDPE. Kujeka kwayo kwakanyanya kunoita kuti chitarisiko chekushandisa PLA sechinhu chekurongedza chitaridzike zvakanaka. Semuenzaniso, inoshandiswa pakurongedza masiwiti. Parizvino, mapakiti mazhinji emasiwiti ari pamusika anoshandisa mafirimu ekurongedza ePLA.
Chitarisiko uye mashandiro efirimu iri rekurongedza akafanana nemafirimu echinyakare ekurongedza masiwiti, ane kujeka kwakanyanya, kuchengetedza kink kwakanaka, kudhindwa uye simba, pamwe nehunhu hwakanaka hwekudzivirira, izvo zvinogona kuchengetedza kunaka kwemasiwiti zviri nani. Kambani yekuJapan inoshandisa brand ye "racea" PLA yeAmerican Cakir Dow Polymer Company sechigadzirwa chekurongedza zvigadzirwa zvitsva, uye kurongedza kwacho kwakajeka zvikuru. Toray Industries yakagadzira mafirimu anoshanda ePLA nezvidimbu ichishandisa tekinoroji yayo ye nano-alloy. Firimu iri rine kusimba kwakafanana nekupisa uye kukanganiswa nemafirimu akavakirwa papetroleum, asi rinewo kusimba uye kujeka kwakanaka.
PLA inogona kugadzirwa kuita zvigadzirwa zvemafirimu zvine kujeka kwakanyanya, hunhu hwakanaka hwekudzivirira, kugona kugadzikiswa uye hunhu hwemakanika, uye inogona kushandiswa pakurongedza michero nemiriwo nenzira inochinjika. Inogona kugadzira nzvimbo yakakodzera yekuchengetera michero nemiriwo, kuchengetedza hupenyu hwemichero nemiriwo, kunonoka kukwegura, uye kuchengetedza ruvara, kunhuhwirira, kuravira uye chitarisiko chemichero nemiriwo. Zvisinei, kana ikashandiswa pazvinhu zvekurongedza zvekudya, dzimwe shanduko dzinodiwa kuti dzienderane nehunhu hwechikafu pachacho, kuitira kuti pave nemhedzisiro iri nani yekurongedza.
PLA inogona kuumba nzvimbo ine acid shoma pamusoro pechigadzirwa, iyo ine hwaro hwemabhakitiriya nemafungus. Kana mimwe mishonga inorwisa mabhakitiriya ikashandiswawo, huwandu hwemabhakitiriya hunopfuura 90% hunogona kuwanikwa, hunogona kushandiswa pakurongedza zvigadzirwa zvinorwisa mabhakitiriya.
Zvichienzaniswa nefirimu reLDPE, firimu rePLA nefirimu rePLA/REO/TiO2, kupindira kwemvura kwefirimu rePLA/REO/Ag kwakakwira zvakanyanya kupfuura kwemamwe mafirimu. Kubva pane izvi, zvinoonekwa kuti inogona kudzivirira kuumbwa kwemvura yakavharirwa uye kuita kuti tupukanana tusakure; panguva imwe chete, inewo simba rakanaka remabhakitiriya.
Mutsetse wePET/PLA wekuchengetedza zvakatipoteredza: JWELL inogadzira mutsetse wekuwedzera wePET/PLA weparallel twin screw, mutsetse uyu une system yekubvisa gassing, uye hapana chikonzero chekuomesa nekugadzira crystallizing unit. Mutsetse wekuwedzera une hunhu hwe low energy comsuption, maitiro ekugadzira ari nyore uye kugadzirisa kuri nyore. Chimiro che screw chakakamurwa chinogona kuderedza kurasikirwa kwe PET/PLA resin, symmetrical uye thin-wall calender roller inowedzera kutonhora uye kuvandudza kugona uye kunaka kwe sheet. Multi components dosing feeder inogona kudzora huwandu hwe virgin material, recycling material uye master batch chaizvo, sheet inoshandiswa zvakanyanya muindasitiri ye thermoforming packaging.
