Chii chinonzi kuiswa kwepurasitikifmaIlms?

Mafirimu epurasitiki anomiririra boka guru rezvinhu zvakagadzirwa nepolymeric zvinoratidzwa nehunhu hwazvo hwakatetepa, hunochinjika uye nzvimbo yakakura pamusoro. Zvinhu izvi zvakagadzirwa nekugadzira ma polymer resins—zvingave zvinobva mupetroleum kana kuti zvinobva muzvinhu zvinodzokororwa—kuita mapepa anoenderera mberi ane ukobvu, upamhi, uye hunhu hwemakanika hwakanyatsodzorwa. Musika wepasi rose wemafirimu epurasitiki wakura zvakanyanya kubvira pawakatanga pakati pezana remakore rechi20, nekugadzirwa kwegore negore kunopfuura matani mamiriyoni zana pasi rose.

Kuchinja-chinja kwemafirimu epurasitiki kunobva mukusanganiswa kwawo kwakasiyana kwezvinhu: kureruka asi kunogara kwenguva refu, kunochinjika asi kwakasimba, uye kunoonekera kana kusaonekwa zvichienderana nezvinodiwa pakugadzira. Hunhu uhwu, pamwe chete nemari shoma yekugadzira, hwakaita kuti mafirimu epurasitiki ave akakosha muzvikamu zvese zveindasitiri yemazuva ano uye hupenyu hwezuva nezuva. Kubva pakuchengetedza chikafu chitsva kusvika pakugonesa michina yemagetsi inochinjika, mafirimu epurasitiki anoita mabasa asingawanzoonekwi nevashandisi vekupedzisira asi akakosha pakushanda kwechigadzirwa uye kuchengetedzeka.

Kufambira mberi munguva pfupi yapfuura musainzi yezvinhu kwakavandudza kugona kwemafirimu epurasitiki kupfuura mabasa avo echinyakare. Zvinhu zvitsva zvinosanganisira mafirimu anochinja hunhu nekuda kwezvikonzero zvezvakatipoteredza, dzimwe nzira dzinoora dzinoshandiswa panzvimbo pepurasitiki dzechinyakare, uye mafirimu ekudzivirira anoshanda zvakanyanya ane hunyanzvi hwekudzivirira husati hwamboonekwa. Panguva imwe chete, kunetseka kuri kukura kwezvakatipoteredza kwakakurudzira kugadzirwa kwemasisitimu ekudzokorodza zvinhu akavharika uye zvinhu zvemafirimu zvakagadzirwa nebio zvinochengetedza mashandiro uku zvichideredza kukanganisa kwezvakatipoteredza.

Rudzii rwefirimu repurasitiki?

Mafirimu Anonyanya Kuwanikwa

Mafirimu epolyethylene ndiwo anonyanya kushandiswa mumhando yefirimu repurasitiki, zvichiita kuti ipfuure 40% yemafuta ese epurasitiki anoshandiswa. Mhando Huru uye Hunhu hwemafirimu epolyethylene:

1. Firimu rePolyethylene Rinorema Zvishoma (LDPE)

Mafirimu eLDPE anozivikanwa nekuchinjika kwawo, kujeka, uye kusanhuwa, uye hunyanzvi hwavo. Ane hunhu hwakanaka hwekudzivirira mvura, hunodzivirira hunyoro, uye kugadzikana kwemakemikari, zvichiita kuti akwanise kurongedza chikafu, mishonga, uye zvigadzirwa zvinoshandiswa zuva nezuva. Mafirimu eLDPE ane hunhu hwakanaka hwekudzivirira kupisa uye anowanzo shandiswa sezvikamu zvekuvhara kupisa mumafirimu akabatanidzwa. Zvisinei, haana hunhu hwakanaka hwekudzivirira kupisa uye haana kukodzera kurongedza pakubika panopisa zvakanyanya.

2. Firimu rePolyethylene Rakakora (HDPE)

Mafirimu eHDPE akaomarara, anopenya zvishoma, uye ane ruvara ruchena. Anoratidza simba guru rekudhonza, anodzivirira hunyoro, anodzivirira kupisa, uye anodzivirira mafuta zvichienzaniswa neLDPE. HDPE yakakodzera kurongedza kwenguva refu uye mafirimu emuindasitiri asi haina kujeka uye haina kupenya zvakanyanya.

3. Firimu rePolyethylene Rinoyerera Nekuderera Kwesimba (LLDPE)

Mafirimu eLLDPE anosanganisa kuchinjika kweLDPE nesimba reHDPE, zvichipa hunhu hwakanaka hwekutambanudza uye kuramba kuboorwa. Anoshandiswa zvakanyanya mumafirimu ekutambanudza, mafirimu ekutetepa, uye mafirimu ekuputira, zvichiita kuti ave akakodzera kurongedza otomatiki nekukurumidza.

4. Metallocene Linear Low-Density Polyethylene Film (mLLDPE)

Mafirimu eMLLDPE anogadzirwa achishandisa metallocene catalysts uye anopa simba guru rekusimba, simba rekusimba, uye kujeka zviri nani kana tichienzanisa neLLDPE yakajairika. Anobvumira kudzikiswa kweukobvu hwefirimu neanopfuura 15%, nokudaro achideredza mitengo yezvinhu. MLLDPE inowanzoshandiswa mumafirimu egreenhouse, mafirimu ekurongedza ane mutoro mukuru, mafirimu ekupfupisa, uye zvinhu zvekurongedza zvepamusoro.

Mamwe Mafirimu epurasitiki

1. Mafirimu ePolypropylene (PP): Anozivikanwa nekunyunguduka kwawo kwakanyanya (160-170°C), zvichiita kuti akwanise kushandiswa pakuisa zvinhu zvinopisa uye pakurongedza zvakanaka mu microwave. Mafirimu ePP haapi makemikari akanaka uye anowanzo shandiswa pakurongedza zvekudya zvekudya zvidiki uye pakuputira michina yekurapa.

2. Mafirimu ePolyvinyl Chloride (PVC): Anokosheswa nekuti akajeka uye anogona kudhindwa zvakanaka asi ari kuramba achishandiswa nekuda kwezvikonzero zvakasiyana-siyana. Mamwe mashandisirwo asara anosanganisira kurongedza mablister uye mamwe mafirimi ekubatanidza.

3. Mafirimu ePolyester (PET): Ane simba guru rekudhonza uye kugadzikana kwekupisa, mafirimu ePET akakosha pakushandisa magetsi anochinjika, matepi emagineti, uye kurongedza chikafu zvine muganho wakakwirira. PET (BOPET) inotarisa biaxially inoratidza hunhu hwemakanika uye hwekudzivirira hwakanyanya.

Mafirimu ePolymer Akakosha:

1. Polyamide (Nylon): Hunhu hwakanaka hwekuchengetedza okisijeni mukuchengetedza chikafu

2. Polyvinylidene Chloride (PVDC): Kushanda zvakanaka kwehunyoro nekudzivirira okisijeni

3. Polylactic Acid (PLA): Imwe nzira iri kubuda kubva kuzvinhu zvipenyu ine hunyoro, kunyange zvazvo yagara ichidzikiswa nekuoma kwayo—kufambira mberi kwazvino kwagadzira mafirimu ePLA anochinjika nekuisa mapurasitiki epolyether zvakananga mucheni yepolymer.

Nzira dzekugadzira mafirimu epurasitiki

1. Kuburitswa Kwemafirimu Akaputika: Maitiro makuru emafirimu ePE, apo polymer yakanyungudutswa inoburitswa kuburikidza nedhizi rakatenderera, yofefeterwa kuita bubble, uye yotonhodzwa kuti igadzire chubhu inogona kupfava kuita firimu rine mativi maviri. Nzira iyi inopa hunhu hwakaringana hwemakanika mumichina nemativi akachinjika.

2. Kuburitswa kweFirimu reCast: Polymer melt inoburitswa kuburikidza neflat die kuenda paroll inotonhorera, zvichigadzira mafirimu akajeka zvikuru uye ukobvu hwakaenzana. Anowanzo kuwanikwa mumafirimu ePP nePET uko hunhu hweoptical hwakakosha.

3. Kugadzira Calendar: Inonyanya kushandiswa kumafirimu ePVC, uko polymer compound inopfuudzwa nemumaroller anodziya kuti iwane kudzora ukobvu kwakanyatsojeka. Mafirimu ane Calendar anowanzo kuve nepamusoro pepamusoro asi ane hunhu husina kufanana hwemakanika pahupamhi.

4. Kugadzira Mhinduro: Inoshandiswa pamafirimu akasarudzika apo kufanana kwakanyanya kana kunzwa kupisa kunodzivisa kunyunguduka. Iyo polymer inonyungudutswa mu solvent, inokandwa pabhandi, uye inoomeswa kuti iite firimu—inowanzo shandiswa mumafirimu anoora uye ma membrane applications.

5. Kutarisa Biaxial: Mafirimu anotambanudzwa mumichina nemativi akachinjika, kungave zvakatevedzana (furemu yetenter) kana panguva imwe chete (maitiro ebubble), zvichivandudza simba, kujeka, uye hunhu hwezvipingamupinyi. Mafirimu ePP (BOPP) nePET (BOPET) ane biaxial ndiwo mwero weindasitiri wekurongedza kwepamusoro-soro.

Mafambiro Ari Kubuda Uye Kuvandudzwa Mumafirimu Epurasitiki

Indasitiri yemafirimu epurasitiki iri kuchinja, ichinyanya kusimbisa kuchengetedza, kushanda, uye kushanda zvakanaka. Mamwe maitiro anozivikanwa anosanganisira:

1.Vamiririri vePFAS-Vasina Kutsvedza:Mishonga inotsvedza inogara kwenguva refu inodzivirira zvinhu zveper- uye polyfluoroalkyl (PFAS), ichigadzirisa zvinodiwa pakushanda zvakanaka uye zvinonetsa zvakatipoteredza.

2. Zvirongwa zveKuchengetedza Zvine Chekuita Nekuchengetedza: Makambani akaita seFox Packaging akabudirira kubvisa PFAS kubva musarudzo dzavo dzese dzemapakeji anochinjika, zvichienderana nemutemo wakakura uye mafambiro eindasitiri. US FDA yakawana zvisungo zvekuzvidira zvekubvisa PFAS kubva mumapakeji ezvekudya, zvichibatsira mukuderedza zvakanyanya kusvibiswa kwePFAS muzvekudya.

Mhinduro itsva dzePFAS-Free processing dzinobatsira mafirimu epurasitiki kubva kuSILIKE

SILIKE inoshandisa nzira yekukurumidza kugadzira zvigadzirwa zvayo zveSILIMER, ichipa zvinhu zvitsvaZvishandiso zvekugadzirisa polymer zvisina PFAS (PPAS)). Iyi mhando yakazara yechigadzirwa ine maPPA asina PFAS 100%, zvigadzirwa zvePPA zvisina fluorine, uye mamasterbatches ePPA asina fluorine, asina PFAS. Nekubvisa kudiwa kwezvinowedzera fluorine, zvigadzirwa izvi zvinovandudza zvakanyanya maitiro ekugadzira zvigadzirwa zveLLDPE, LDPE, HDPE, mLLDPE, PP, uye mafirimu. Zvinoenderana nemitemo yezvakatipoteredza yazvino ukuwo zvichiwedzera kushanda zvakanaka kwekugadzira, kuderedza nguva yekushanda, uye kuvandudza mhando yechigadzirwa chose. NeSILIKE PFAS-PPA inounza mabhenefiti ekupedzisira eChigadzirwa, anosanganisira: kubvisa kuputsika kweganda reshark, kutsvedzerera kwakawedzerwa, uye kunaka kwenzvimbo.
