Kupaka zinthu mosinthasintha ndi mtundu wa kupaka zinthu zopangidwa ndi zinthu zosinthasintha zomwe zimaphatikiza ubwino wa pulasitiki, filimu, mapepala ndi zojambula za aluminiyamu, zomwe zimakhala ndi zinthu monga zopepuka komanso zosavuta kunyamula, kukana bwino mphamvu zakunja, komanso kukhalitsa. Zina mwa zinthu zomwe zimagwiritsidwa ntchito popaka zinthu mosinthasintha ndi makamaka filimu ya pulasitiki, zojambula za aluminiyamu, zinthu zopangidwa ndi zamoyo, zinthu zokutidwa, kupaka zinthu zowola ndi zina zotero.

Ma phukusi osinthika a zinthu ndi awa: matumba, filimu yozungulira, matumba ogulitsa zakudya, kukulunga pang'ono, filimu yotambasula ndi kukulunga madzi m'mabotolo. Makhalidwe apadera a zinthuzi pankhani ya mphamvu ya makina, kugwiritsa ntchito bwino zotchinga (monga kuteteza chakudya ku kuipitsidwa), kupirira kusindikizidwa, kukana kutentha, mawonekedwe owoneka bwino (monga kunyezimira kwambiri komanso kumveka bwino), kubwezeretsanso, komanso kugwiritsa ntchito bwino ndalama ndi zomwe zimawapangitsa kukhala apadera.

Pakati pawo, mafilimu apulasitiki amagwiritsidwa ntchito poika zinthu zosiyanasiyana m'mabokosi osiyanasiyana, kuphatikizapo izi:

Polyethylene (PE): kuphatikizapo polyethylene yotsika kwambiri (LDPE) ndi polyethylene yotsika kwambiri (LLDPE), yomwe imagwiritsidwa ntchito kwambiri mkati mwa zida zopangira chakudya, yokhala ndi mphamvu zabwino zotsekera kutentha komanso kusinthasintha.

Polypropylene (PP): imagwiritsidwa ntchito kwambiri popanga filimu, yokhala ndi kukana kutentha bwino komanso kukana mankhwala, yomwe imagwiritsidwa ntchito kwambiri popanga zinthu zoyambira.

Polyester (PET): imagwiritsidwa ntchito kwambiri ngati gawo lakunja kapena lapakati la phukusi chifukwa cha mawonekedwe ake abwino a makina komanso kuwonekera bwino, zomwe zimapangitsa kuti ikhale yolimba komanso yokongola.

Nayiloni (PA): imapereka zinthu zabwino zotchingira ndipo nthawi zambiri imagwiritsidwa ntchito popaka zinthu zomwe zimafuna kuti zinthuzo zikhale zotchingira kwambiri.

Ethylene vinyl acetate copolymer (EVA): Imapereka kusinthasintha kwabwino komanso kumamatira ndipo nthawi zambiri imagwiritsidwa ntchito ngati gawo lotsekera kutentha.

Polyvinylidene dichloride (PVDC): ili ndi mphamvu zambiri zotchinga mpweya ndi chinyezi, zomwe zimagwiritsidwa ntchito kwambiri popakira zomwe zimafuna kutsitsimuka kwa nthawi yayitali.

Ethylene Vinyl Alcohol Copolymer (EVOH): imapereka mphamvu zabwino kwambiri zotchingira mpweya ngati chotchinga.

Polyvinyl chloride (PVC): imagwiritsidwa ntchito m'magwiritsidwe ena, koma kugwiritsidwa ntchito kwake kumakhala kochepa chifukwa cha nkhawa zachilengedwe ndi thanzi.

Zipangizo zochokera ku bio: monga polylactic acid (PLA), monga chinthu china chosawononga chilengedwe chomwe chimatha kuwonongeka mosavuta.

Zipangizo zomwe zimawola: akupangidwa kuti achepetse kuwonongeka kwa zinthu zomwe zimayikidwa m'mabokosi.

Mafilimu ophatikizika amitundu yambiri: Kuphatikiza kwa PA, EVOH, PVDC ndi ma resin monga PE, EVA, PP, ndi zina zotero kuti kupereke mphamvu zotchinga kwambiri.

Zipangizozi zitha kugwiritsidwa ntchito payekhapayekha kapena kuphatikizana kuti zipange mafilimu ophatikizika kuti zikwaniritse zofunikira zosiyanasiyana zolongedza monga zinthu zotchinga, kutsekeka kwa kutentha, mphamvu yamakina ndi kukongola. Mu zolongedza zosinthasintha, zipangizozi nthawi zambiri zimaphatikizidwa ndi njira zolumikizira kapena zotulutsira pamodzi kuti zipange zida zolongedza zokhala ndi ntchito zinazake.

Momwe mungathetsere vuto la PE, PP, PET, PA ndi zipangizo zina pokonza njira yotulutsira zinthu zomwe zimakhala ndi vuto la extrusion?

Zipangizo zomwe zili pamwambazi, monga PE, PP, PET, PA, ndi zina zotero, zimatha kusungunuka mkamwa, kusungunuka pang'onopang'ono, kusungunuka kwa madzi, komanso malo otuluka omwe ali ndi vuto panthawi yokonza ndi kutulutsa madzi. Nthawi zambiri, opanga akuluakulu amawonjezera zothandizira kukonza zinthu za polymer PPA zomwe zili ndi fluorine kuti ziwongolere magwiridwe antchito opangira zinthu. Komabe, m'zaka zaposachedwa, chifukwa cha kudziwika bwino kwa chitetezo cha chilengedwe komanso lamulo loletsa kugwiritsa ntchito Fluoride, kupeza njira zina m'malo mwa zothandizira kukonza zinthu za polymer PPA zomwe zili ndi fluorine kwakhala ntchito yofunika kwambiri.

Padziko lonse lapansi, PFAS imagwiritsidwa ntchito kwambiri m'mafakitale ambiri komanso m'zinthu zogulira, koma chiopsezo chake ku chilengedwe ndi thanzi la anthu chadzetsa nkhawa kwambiri. Ndi European Chemicals Agency (ECHA) yomwe yalengeza za lamulo la PFAS.

Mu 2023, gulu la SILIKE la R&D layankha momwe zinthu zilili masiku ano ndipo lagwiritsa ntchito mphamvu zambiri pogwiritsa ntchito njira zamakono komanso malingaliro atsopano kuti lipitirire patsogolo.Zothandizira polima zopanda PFAS (PPAs), zomwe zimathandiza kwambiri kuteteza chilengedwe ndi chitukuko chokhazikika. Katunduyu amatsimikizira kuti zinthuzo zikugwira ntchito bwino komanso kuti zinthuzo zikhale bwino komanso kuti zinthuzo zisamawonongeke komanso kupewa zoopsa zachilengedwe komanso zaumoyo zomwe mankhwala achikhalidwe a PFAS angabweretse.

SILIKE SILIMER PPA-free PPAS masterbatch ndi pulogalamu yothandizira kukonza ma polima yopanda PFAS (PPAS)Chowonjezeracho ndi polysiloxane yosinthidwa mwachilengedwe, yomwe imagwiritsa ntchito mphamvu yabwino kwambiri yoyambira ya mafuta a polysiloxanes ndi mphamvu ya polar ya magulu osinthidwa kuti asamuke ndikuchitapo kanthu pa zida zokonzera panthawi yokonza.

SILIKE SILIMER PFAS wopanda PPA masterbatchKungakhale njira yabwino kwambiri yogwiritsira ntchito PPA yochokera ku fluorine, kuwonjezera pang'ono kungathandize bwino kusinthasintha kwa utomoni, kusinthasintha, ndi kukhuthala komanso mawonekedwe a pamwamba pa pulasitiki, kuchotsa kuphulika kwa kusungunuka, kusintha kukana kukalamba, kuchepetsa kukhuthala, kukonza kupanga ndi khalidwe la zinthu, komanso kusamala chilengedwe komanso kotetezeka.

SILIKE SILIMER PFAS wopanda PPA masterbatchIli ndi ntchito zosiyanasiyana, osati za mafilimu apulasitiki okha, komanso za mawaya ndi zingwe, machubu, ma masterbatches amitundu, makampani opanga mafuta ndi zina zotero.

Ngati muli mumakampani opanga ma CD osinthasintha ndipo mukufuna kukonza mpikisano wa zinthu zanu, mutha kugwiritsa ntchitoZowonjezera za PPA zopanda PFAS za SILIKE.
