Cov khoom ntim khoom yooj ywm yog ib hom khoom ntim khoom ua los ntawm cov khoom siv yooj ywm uas muab cov txiaj ntsig ntawm yas, zaj duab xis, ntawv thiab ntawv ci txhuas, nrog rau cov yam ntxwv xws li lub teeb yuag thiab yooj yim nqa, tiv taus cov zog sab nraud, thiab kev ruaj khov. Qee cov khoom siv hauv cov khoom ntim khoom yooj ywm feem ntau yog zaj duab xis yas, ntawv ci txhuas, cov khoom siv bio-based, cov khoom siv coated, cov khoom ntim biodegradable thiab lwm yam.

Cov khoom siv ntim khoom yooj ywm muaj xws li: hnab, zaj duab xis qhwv ib puag ncig, hnab nqa khoom noj, qhwv ntsws, zaj duab xis ncab thiab ntim dej fwj. Cov yam ntxwv tshwj xeeb ntawm cov khoom no hais txog lub zog kho tshuab, kev ua haujlwm zoo ntawm kev thaiv (piv txwv li, kev tiv thaiv cov khoom noj los ntawm kev ua qias tuaj), kev ua haujlwm luam tawm, kev tiv taus kub, kev pom zoo (piv txwv li, ci ntsa iab thiab meej), kev siv rov qab tau, thiab kev siv nyiaj tsim nyog yog qhov ua rau lawv sawv tawm.

Ntawm lawv, cov yas yas siv rau hauv cov ntim khoom yooj ywm hauv ntau yam khoom siv sib txawv, suav nrog cov hauv qab no:

Polyethylene (PE): suav nrog cov polyethylene qis-density (LDPE) thiab linear qis-density polyethylene (LLDPE), feem ntau siv rau hauv txheej sab hauv ntawm cov khoom ntim khoom noj, nrog cov khoom zoo sealing kub thiab yooj ywm.

Polypropylene (PP): feem ntau siv rau hauv kev tsim cov yeeb yaj kiab, nrog kev tiv thaiv cua sov zoo heev thiab tshuaj lom neeg tsis kam, feem ntau siv rau hauv cov ntaub ntawv hauv paus.

Polyester (Tsiaj): feem ntau siv ua txheej sab nraud lossis nruab nrab ntawm cov ntim khoom vim nws cov khoom siv kho tshuab zoo thiab pob tshab, muab lub zog thiab kev zoo nkauj.

Nylon (PA): muab cov khoom thaiv zoo thiab feem ntau siv rau kev ntim khoom uas xav tau kev ua haujlwm thaiv siab.

Ethylene vinyl acetate copolymer (EVA): Muab kev ywj pheej zoo thiab kev nplaum zoo thiab feem ntau siv ua txheej txheej kaw cua sov.

Polyvinylidene dichloride (PVDC): muaj cov khoom tiv thaiv huab cua thiab dej noo siab heev, feem ntau siv rau hauv kev ntim khoom uas xav tau kev tshiab mus sij hawm ntev.

Ethylene Vinyl Cawv Copolymer (EVOH): muab cov khoom tiv thaiv oxygen zoo heev ua ib txheej thaiv.

Polyvinyl chloride (PVC): siv rau hauv qee daim ntawv thov, tab sis nws siv tsawg vim yog kev txhawj xeeb txog ib puag ncig thiab kev noj qab haus huv.

Cov ntaub ntawv bio-based: xws li polylactic acid (PLA), ua ib yam khoom siv zoo rau ib puag ncig nrog kev puas tsuaj zoo biodegradability.

Cov khoom siv uas lwj tau: tab tom raug tsim los txo qhov cuam tshuam rau ib puag ncig ntawm kev ntim khoom.

Cov yeeb yaj kiab sib xyaw ua ke ntau txheej: Kev sib xyaw ua ke ntawm ntau txheej ntawm PA, EVOH, PVDC nrog cov resins xws li PE, EVA, PP, thiab lwm yam los muab cov khoom thaiv siab.

Cov ntaub ntawv no siv tau ib leeg lossis ua ke los ua cov zaj duab xis sib xyaw kom ua tau raws li cov kev xav tau ntawm kev ntim khoom sib txawv xws li cov yam ntxwv thaiv, kev kaw cua sov, lub zog kho tshuab thiab kev zoo nkauj. Hauv kev ntim khoom yooj ywm, cov ntaub ntawv no feem ntau yog ua ke los ntawm kev lamination lossis cov txheej txheem co-extrusion los ua cov ntaub ntawv ntim khoom nrog cov haujlwm tshwj xeeb.

Yuav ua li cas daws qhov teeb meem ntawm PE, PP, PET, PA thiab lwm yam ntaub ntawv hauv kev ua cov txheej txheem extrusion uas muaj qhov tsis zoo?

Cov ntaub ntawv saum toj no, xws li PE, PP, PET, PA, thiab lwm yam, feem ntau yuav ua rau lub qhov ncauj tuag tsim, qeeb qeeb dua qhov extrusion, yaj tawg, thiab cov nplaim extruded tsis zoo thaum lub sijhawm ua thiab extrusion. Feem ntau, cov chaw tsim khoom loj yuav ntxiv cov tshuaj fluorinated polymer PPA ua cov khoom pab kom txhim kho kev ua haujlwm. Txawm li cas los xij, nyob rau xyoo tas los no, nrog rau kev paub txog kev tiv thaiv ib puag ncig thiab Fluoride Restriction Order, nrhiav lwm txoj hauv kev rau cov tshuaj fluorinated polymer PPA ua cov khoom pab tau dhau los ua ib txoj haujlwm ceev.

Thoob ntiaj teb, PFAS siv dav hauv ntau yam khoom lag luam thiab cov khoom siv rau cov neeg siv khoom, tab sis nws qhov kev pheej hmoo rau ib puag ncig thiab kev noj qab haus huv ntawm tib neeg tau ua rau muaj kev txhawj xeeb dav dav. Nrog rau European Chemicals Agency (ECHA) tshaj tawm rau pej xeem daim ntawv qhia txog kev txwv PFAS.

Xyoo 2023, pab pawg R&D ntawm SILIKE tau teb rau qhov sib txawv ntawm lub sijhawm thiab tau nqis peev ntau lub zog los siv cov cuab yeej siv thev naus laus zis tshiab thiab kev xav tshiab los tsim kom zooCov khoom siv ua cov polymer uas tsis muaj PFAS (PPAs), uas ua rau muaj kev pab txhawb zoo rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov. Cov khoom no ua kom ntseeg tau tias kev ua haujlwm ntawm cov khoom siv thiab qhov zoo thaum zam kev pheej hmoo ntawm ib puag ncig thiab kev noj qab haus huv uas cov tshuaj PFAS ib txwm muaj.

SILIKE SILIMER PFAS-free PPA masterbatch yog ib qho khoom siv polymer processing aid (PPA) uas tsis muaj PFAS.Silicone tau qhia. Cov khoom ntxiv yog cov polysiloxane uas tau hloov kho kom zoo, uas siv qhov zoo ntawm cov nyhuv roj nplua nyeem zoo heev ntawm cov polysiloxanes thiab cov nyhuv polar ntawm cov pab pawg hloov kho kom txav mus los thiab ua rau cov khoom siv ua haujlwm thaum lub sijhawm ua haujlwm.

SILIKE SILIMER PFAS-dawb PPA masterbatchtuaj yeem ua ib qho kev hloov pauv zoo meej rau cov khoom siv ua PPA uas muaj fluorine, ntxiv me me tuaj yeem txhim kho cov kua nplaum, kev ua haujlwm, thiab lubricity thiab cov yam ntxwv ntawm cov yas extrusion, tshem tawm qhov tawg ntawm cov yaj, txhim kho kev hnav tsis kam, txo cov coefficient ntawm kev sib txhuam, txhim kho kev tsim khoom thiab cov khoom zoo, tab sis kuj zoo rau ib puag ncig thiab muaj kev nyab xeeb.

SILIKE SILIMER PFAS-dawb PPA masterbatchmuaj ntau yam kev siv, tsis yog rau cov yas zaj duab xis xwb, tab sis kuj rau cov xov hlau thiab cov cables, cov raj, cov xim masterbatches, kev lag luam petrochemical thiab lwm yam.

Yog tias koj nyob hauv kev lag luam ntim khoom yooj ywm thiab tab tom nrhiav kev txhim kho kev sib tw ntawm koj cov khoom, koj tuaj yeem sivSILIKE cov tshuaj ntxiv PPA uas tsis muaj PFAS.
