Kurongedza zvinhu zvinochinjika imhando yekurongedza yakagadzirwa nezvinhu zvinochinjika zvinosanganisa zvakanakira purasitiki, firimu, bepa nealuminium foil, ine zvinhu zvakaita sekureruka uye kutakurwa, kuramba zvakanaka kusimba kwekunze, uye kugara kwenguva refu. Zvimwe zvezvinhu zvinoshandiswa pakurongedza zvinhu zvinochinjika zvinosanganisira purasitiki, aluminium foil, zvinhu zvakagadzirwa nebio-based, zvinhu zvakaputirwa, kurongedza kunogona kuora nezvimwewo.

Mashandisirwo ezvigadzirwa zvekurongedza zvinochinjika anosanganisira: mabhegi, firimu rinoputira, mabhegi ezvekudya, kuputira shrink, firimu rekutambanudza uye kuputira mvura mumabhodhoro. Hunhu hwakasiyana hwezvigadzirwa izvi maererano nesimba remuchina, kushanda zvakanaka kwezvinodzivirira (semuenzaniso, kudzivirira chikafu kubva mukusvibiswa), kushivirira kudhinda, kuramba kupisa, chitarisiko chekuona (semuenzaniso, kupenya kwakanyanya uye kujeka), kugona kudzokorodza, uye kushanda zvakanaka kwemari ndizvo zvinoita kuti zvisiyane nevamwe.

Pakati pavo, mafirimu epurasitiki anoshandiswa mukurongedza kunochinjika mumhando dzakasiyana-siyana dzezvinhu, kusanganisira zvinotevera:

Polyethylene (PE): kusanganisira polyethylene yakaderera (LDPE) uye polyethylene yakaderera (LLDPE), inowanzoshandiswa mukati mezvinhu zvekurongedza chikafu, ine hunhu hwakanaka hwekuvhara kupisa uye kuchinjika.

Polypropylene (PP): inowanzoshandiswa mukugadzira firimu, ine simba rekudzivirira kupisa uye makemikari, inowanzoshandiswa muzvinhu zvepasi.

Polyester (PET): inowanzoshandiswa sechikamu chekunze kana chepakati chekurongedza nekuda kwehunhu hwayo hwakanaka hwemakanika uye kujeka, zvichipa simba uye runako.

Naironi (PA): inopa hunhu hwakanaka hwekudzivirira uye inowanzoshandiswa pakurongedza zvinoda kushanda kwakasimba kwekudzivirira.

Ethylene vinyl acetate copolymer (EVA): Inopa kuchinjika kwakanaka uye kunamira uye inowanzoshandiswa sechikamu chekuvhara kupisa.

Polyvinylidene dichloride (PVDC): ine hunhu hwakawanda hwekudzivirira mhepo nehunyoro, hunoshandiswa zvakanyanya mukupakata zvinoda kutsva kwenguva refu.

Ethylene Vinyl Alcohol Copolymer (EVOH): inopa hunhu hwakanaka hwekudzivirira okisijeni sechikamu chekudzivirira.

Polyvinyl chloride (PVC): inoshandiswa mune dzimwe nzira, asi kushandiswa kwayo kwakaganhurirwa nekuda kwezvinetso zvakatipoteredza uye hutano.

Zvinhu zvakagadzirwa neBio: zvakaita sepolylactic acid (PLA), sechinhu chinotsiva zvakatipoteredza chine hunhu hwakanaka uye chinogona kuora.

Zvinhu zvinoora: zviri kugadzirwa kuderedza kukanganisa kunokonzerwa nekurongedza zvinhu munzvimbo.

Mafirimu akawanda akabatanidzwa pamwe chete akawedzerwa: Musanganiswa wePA, EVOH, PVDC une maresini akawanda akadai sePE, EVA, PP, nezvimwewo kuti zvive nehupamhi hwepamusoro hwezvipingamupinyi.

Zvinhu izvi zvinogona kushandiswa chimwe nechimwe kana kusanganiswa kugadzira mafirimu akabatanidzwa kuti zvisangane nezvinodiwa zvakasiyana zvekurongedza zvakaita sezvipingamupinyi, kuvharika kwekupisa, simba remakanika uye runako. Mukurongedza kunochinjika, zvinhu izvi zvinowanzo sanganiswa nemaitiro e lamination kana co-extrusion kuti zvigadzire zvinhu zvekurongedza zvine mabasa chaiwo.

Maitiro ekugadzirisa dambudziko rePE, PP, PET, PA nezvimwe zvinhu mukugadzirisa maitiro ekuwedzera anowanzo kanganisa?

Zvinhu zvataurwa pamusoro apa, zvakaita sePE, PP, PET, PA, nezvimwewo, zvinogona kukonzera muromo kuungana, kuwedzera kwemvura inobuda zvishoma nezvishoma, kuputika kwemvura inonyunguduka, uye nzvimbo dzakabuda dzisina kunaka panguva yekugadzirisa nekubvisa. Kazhinji, vagadziri vakuru vanowedzera zvinhu zvinobatsira pakugadzirisa polymer PPA kuti vavandudze mashandiro ekugadzirisa. Zvisinei, mumakore achangopfuura, neruzivo rwuri kukura rwekuchengetedzwa kwezvakatipoteredza uye mutemo weFluoride Restriction Order, kutsvaga dzimwe nzira dzekugadzirisa polymer PPA dzine fluorinated kwave kuri basa guru.

Pasi rose, PFAS inoshandiswa zvakanyanya muzvigadzirwa zvakawanda zvemaindasitiri nevatengi, asi njodzi yayo inogona kuitika kunharaunda nehutano hwevanhu yakonzera kunetseka kukuru. NeEuropean Chemicals Agency (ECHA) ichizivisa pachena gwaro remutemo wePFAS.

Muna 2023, timu yeSILIKE yeR&D yakapindura kune zviri kuitika munguva iyoyo uye yakaisa simba rakawanda mukushandisa nzira dzetekinoroji dzazvino uye mafungiro matsva kuti ibudirire.Zvishandiso zvekugadzirisa polymer zvisina PFAS (PPAS), izvo zvinopa mupiro wakanaka mukuchengetedzwa kwezvakatipoteredza uye budiriro inoenderera mberi. Chigadzirwa ichi chinovimbisa kushanda zvakanaka uye kunaka kwezvinhu zvakagadzirwa ukuwo chichidzivirira njodzi dzezvakatipoteredza nehutano dzingaunzwa nemakemikari echinyakare ePFAS.

SILIKE SILIMER PPA isina PFAS masterbatch ibatsiro rekugadzirisa polymer risina PFAS (PPAS)yakaunzwa neSilicone. Chinowedzera ichi ipolysiloxane yakagadziriswa organically, iyo inoshandisa mukana wekutanga wekunyorovesa mapolysiloxanes uye polar effect yemapoka akagadziriswa kuti afambe uye ashande pamidziyo yekugadzirisa panguva yekugadzirisa.

SILIKE SILIMER PFAS-yemahara PPA masterbatchInogona kuva chinhu chakanaka chinotsiva zvinhu zvinobatsira pakugadzirisa PPA zvichibva pafluorine, kuwedzera huwandu hushoma kunogona kuvandudza kuyerera kwe resin, kugona kwayo kugadzika, uye kunyorova uye hunhu hwepamusoro hwepurasitiki inobuda, kubvisa kuputika kwekunyunguduka, kuvandudza kuramba kupfeka, kuderedza coefficient yekukweshana, kuvandudza kugadzirwa uye kunaka kwechigadzirwa, asiwo kuchengetedza nharaunda.

SILIKE SILIMER PFAS-yemahara PPA masterbatchine mashandisirwo akasiyana-siyana, kwete chete kumafirimu epurasitiki, asiwo kune waya netambo, machubhu, mavara makuru, indasitiri yepetrochemical nezvimwewo.

Kana uri muindasitiri yekurongedza zvinhu zvinochinjika uye uchida kuvandudza kukwikwidzana kwezvigadzirwa zvako, unogona kushandisaZvimwe zveSILIKE zvePPAS zvisina PFAS zvePPA.
