Kuyika kwa flexible ndi mtundu wa ma CD opangidwa kuchokera ku zipangizo zosinthika zomwe zimaphatikiza ubwino wa pulasitiki, filimu, mapepala ndi zojambulazo za aluminiyamu, zokhala ndi zinthu monga zopepuka komanso zosavuta, kukana bwino kwa mphamvu zakunja, ndi kukhazikika. Zina mwazinthu zomwe zimagwiritsidwa ntchito poyikapo zosinthika makamaka ndi filimu yapulasitiki, zojambulazo za aluminiyamu, zida zochokera ku bio, zida zokutira, zoyikapo zowonongeka ndi zina zotero.

Ntchito zomangira zosinthika zimaphatikizirapo: matumba, filimu yokulunga mozungulira, matumba azogulitsira, zomata zocheperako, filimu yotambasula ndi kuyika madzi m'mabotolo. Makhalidwe apadera a zinthuzi malinga ndi mphamvu zamakina, mphamvu zotchinga (mwachitsanzo, kuteteza chakudya kuti zisaipitsidwe), kulekerera kusindikiza, kukana kutentha, mawonekedwe owoneka bwino (mwachitsanzo, gloss ndi kumveka bwino), kubwezeredwa, komanso kutsika mtengo ndi zomwe zimapangitsa iwo amaonekera.

Pakati pawo, mafilimu apulasitiki amagwiritsidwa ntchito muzotengera zosinthika muzinthu zosiyanasiyana, kuphatikizapo izi:

Polyethylene (PE): kuphatikizapo otsika osalimba polyethylene (LDPE) ndi liniya otsika kachulukidwe polyethylene (LLDPE), kawirikawiri ntchito wosanjikiza wamkati wa zinthu ma CD ma CD, ndi katundu wabwino kutentha kusindikiza ndi kusinthasintha.

Polypropylene (PP): Zomwe zimagwiritsidwa ntchito popanga filimu, zokhala ndi kutentha kwambiri komanso kukana kwa mankhwala, zomwe zimagwiritsidwa ntchito pazinthu zapansi.

Polyester (PET): yomwe imagwiritsidwa ntchito ngati wosanjikiza wakunja kapena wapakati wa ma CD chifukwa cha makina ake abwino komanso kuwonekera, kupereka mphamvu ndi kukongola.

Nylon (PA): imapereka zotchinga zabwino ndipo nthawi zambiri imagwiritsidwa ntchito pakuyika zomwe zimafuna magwiridwe antchito apamwamba.

Ethylene vinyl acetate copolymer (EVA): Amapereka kusinthasintha kwabwino komanso kumamatira ndipo nthawi zambiri amagwiritsidwa ntchito ngati wosanjikiza wosindikiza kutentha.

Polyvinylidene dichloride (PVDC): ali ndi mpweya wochuluka kwambiri komanso zotchinga chinyezi, zomwe zimagwiritsidwa ntchito popakira zomwe zimafuna kutsitsimuka kwanthawi yayitali.

Ethylene Vinyl Alcohol Copolymer (EVOH): imapereka zinthu zabwino kwambiri zotchinga mpweya ngati chotchinga chotchinga.

Polyvinyl chloride (PVC): amagwiritsidwa ntchito pazinthu zina, koma kugwiritsidwa ntchito kwake kumakhala kochepa chifukwa cha chilengedwe komanso thanzi.

Zida zochokera ku bio: monga polylactic acid (PLA), monga zinthu zachilengedwe wochezeka ndi biodegradability wabwino.

Zinthu zosawonongeka: akupangidwa kuti achepetse kuwonongeka kwa chilengedwe pakuyika.

Makanema ophatikizika amitundu yambiri: Mipikisano wosanjikiza kuphatikiza PA, EVOH, PVDC ndi utomoni monga PE, EVA, PP, etc. kupereka mkulu zotchinga katundu.

Zidazi zitha kugwiritsidwa ntchito payekhapayekha kapena kuphatikiza kupanga mafilimu ophatikizika kuti akwaniritse zofunikira zonyamula katundu monga zotchinga, kutsekedwa kwa kutentha, mphamvu zamakina ndi kukongola. Mu ma CD osinthika, zinthuzi nthawi zambiri zimaphatikizidwa ndi njira zopangira lamination kapena co-extrusion kuti apange zida zonyamula ndi ntchito zenizeni.

Momwe mungathetsere vuto la PE, PP, PET, PA ndi zida zina pakukonza njira ya extrusion sachedwa kuwonongeka?

Zida zomwe zili pamwambazi, monga PE, PP, PET, PA, ndi zina zotero, zimakhala zosavuta kufa pakamwa, kutulutsa pang'onopang'ono, kusungunuka kwasungunuka, ndi malo opanda pake otuluka panthawi yokonza ndi kutulutsa. Nthawi zambiri, opanga akuluakulu amawonjezera zida zopangira polima PPA kuti apititse patsogolo magwiridwe antchito. Komabe, m'zaka zaposachedwa, ndikukula kwachidziwitso chachitetezo cha chilengedwe komanso Dongosolo Loletsa Fluoride, kupeza njira zina zothandizira polima polima PPA yakhala ntchito yofunika kwambiri.

Padziko lonse lapansi, PFAS imagwiritsidwa ntchito kwambiri pazinthu zambiri zamafakitale ndi ogula, koma chiwopsezo chake ku chilengedwe komanso thanzi la anthu chadzetsa nkhawa. Ndi European Chemicals Agency (ECHA) ikudziwitsa anthu zoletsa za PFAS.

Mu 2023, gulu la R&D la SILIKE lachitapo kanthu pa zomwe zikuchitika masiku ano ndikuyika mphamvu zambiri pakugwiritsa ntchito njira zaukadaulo zaposachedwa komanso malingaliro apamwamba kuti atukule bwino.PFAS-free polima processing aids (PPAs), zomwe zimapereka chithandizo chabwino pachitetezo cha chilengedwe ndi chitukuko chokhazikika. Izi zimawonetsetsa kuti zinthu zikuyenda bwino komanso zabwino zake ndikupewa kuopsa kwa chilengedwe ndi thanzi zomwe mankhwala azikhalidwe a PFAS angabweretse.

SILIKE SILIMER PFAS-free PPA masterbatch ndi PFAS-free polima processing aid (PPA)opangidwa ndi Silicone. Chowonjezeracho ndi polysiloxane yosinthidwa organically, yomwe imagwiritsa ntchito mwayi woyambira bwino wamafuta a polysiloxanes ndi zotsatira za polar zamagulu osinthidwa kuti asamuke ndikuchitapo kanthu pazida zopangira.

SILIKE SILIMER PFAS wopanda PPA masterbatchikhoza kukhala choloweza m'malo mwa fluorine zochokera PPA processing aids, kuwonjezera pang'ono akhoza bwino kusintha utomoni fluidity, processability, ndi lubricity ndi pamwamba makhalidwe a extrusion pulasitiki, kuthetsa kusungunuka kuphulika, kusintha kuvala kukana, kuchepetsa coefficient of kukangana. , kupititsa patsogolo kupanga ndi khalidwe lazogulitsa, komanso kukhala ochezeka komanso otetezeka.

SILIKE SILIMER PFAS wopanda PPA masterbatchali ndi ntchito zosiyanasiyana, osati mafilimu apulasitiki okha, komanso mawaya ndi zingwe, machubu, masterbatches amtundu, makampani a petrochemical ndi zina zotero.

Ngati muli m'makampani osinthira ma CD ndipo mukuyang'ana kuti mupititse patsogolo kupikisana kwazinthu zanu, mutha kugwiritsa ntchitoSILIKE's PFAS-free PPA zowonjezera.
