Cov txiaj ntsig ntawm kev ntxiv Fluorine-Free PPA hauv kev tsim cov nyom dag.

Cov nyom dag siv lub hauv paus ntsiab lus ntawm bionics, uas ua rau tus neeg ncaws pob xav tias ko taw thiab lub pob rov qab ceev zoo ib yam li cov nyom ntuj. Cov khoom muaj qhov kub thiab txias dav, siv tau rau hauv qhov txias, kub siab thiab lwm qhov chaw huab cua hnyav. Thiab siv ua thaj chaw huab cua txhua lub sijhawm, Tsis cuam tshuam los ntawm nag lossis daus, muaj dej permeability zoo, tshwj xeeb tshaj yog haum rau lub sijhawm kawm ntev, kev siv ntau zaus ntawm chaw ntau pob thiab tsev kawm ntawv qib pib thiab theem nrab.

Cov nyom dag feem ntau yog ua los ntawm polyethylene (PE) thiab polypropylene (PP), tab sis kuj muaj polyvinyl chloride (PVC) thiab polyamide (PA). Qhov siab ntawm cov nyom sib txawv ntawm 8mm-75mm kom tau raws li ntau yam kev xav tau kev ua si. Piv nrog cov nyom ntuj, cov yam ntxwv ntuj tsim ntawm cov nyom dag ua rau nws zoo dua li cov nyom ntuj hauv ob qho tib si tsos thiab kev siv.

Txawm li cas los xij, cov nyom dag hauv cov txheej txheem tsim khoom yuav ntsib ntau yam teeb meem ua tiav, xws li cov khoom siv raw hauv cov txheej txheem extrusion yuav tshwm sim qhov roughness ntawm qhov chaw, deformation lossis tawg thiab lwm yam tsis zoo. Yog li muaj ntau rooj plaub uas cov chaw tsim khoom yuav ntxiv qee cov khoom siv ua tiav hauv kev ua cov khoom siv raw ntawm cov nyom dag, suav nrog PPA (Polymer Processing Additive), ntxiv PPA (Polymer Processing Additive) tuaj yeem ua ntau lub luag haujlwm tseem ceeb hauv cov txheej txheem tsim cov nyom dag:

• Kev txhim kho ntawm kev tawg ntawm cov yas: Nws tuaj yeem txo qhov kev sib txhuam sab hauv cov roj hmab hauv cov txheej txheem yas, ua rau kom muaj kev yaj sai thiab kev hloov pauv ntawm cov yas, thiab txo qhov tawg ntawm cov yas.
• Txhim kho kev ua haujlwm lubrication: PPA tuaj yeem txo qhov viscosity yaj hauv kev tsim cov nyom dag, txhim kho qhov fluidity ntawm cov khoom, ua rau cov txheej txheem ntau lawm du thiab txhim kho kev ua haujlwm ntawm extrusion.
• Txhim kho kev tiv thaiv huab cua: Cov nyom dag nyob rau sab nraum zoov yuav tsum tiv taus lub hnub ci ntev, nag, hloov pauv kub thiab lwm yam ntuj tsim los ntawm kev yaig. Ntxiv PPA tuaj yeem txhim kho kev tiv thaiv huab cua ntawm cov khoom nyom dag thiab ua rau nws ruaj khov dua.

Tau ntev heev, cov chaw tsim khoom siv raw rau cov nyom dag tau ntxiv cov PPA uas muaj fluorinated, tab sis nrog rau kev txwv tsis pub siv fluoride, nrhiav lwm txoj hauv kev rau fluorinated PPA tau dhau los ua qhov kev sib tw tshiab.

Ua teb rau qhov no, SILIKE tau qhia txog ib qhoPTFE-dawb lwm txoj hauv kev rau Fluorine-based PPA——ibCov khoom siv ua cov polymer uas tsis muaj PFAS (PPA). Qhov PPA MB no tsis muaj Fluorine,Cov khoom ntxiv uas tsis muaj PTFEyog ib qho organically hloov kho polysiloxane masterbatch uas siv cov nyhuv zoo heev ntawm polysiloxanes thiab polarity ntawm cov pab pawg hloov kho kom migrating thiab ua rau cov khoom siv ua haujlwm thaum lub sijhawm ua haujlwm.

Tshwj xeeb tshaj yog,SILIKE SILIMER 5090yog ib qhoCov khoom siv ua khoom siv uas tsis muaj fluorinerau kev rho tawm cov khoom siv yas nrog PE ua tus neeg nqa khoom uas peb lub tuam txhab tau tsim tawm. Nws yog ib qho organic hloov khopolysiloxane masterbatchcov khoom, uas tuaj yeem hloov mus rau cov khoom siv ua haujlwm thiab muaj cov nyhuv thaum lub sijhawm ua haujlwm los ntawm kev siv qhov zoo ntawm cov nyhuv pib lubrication ntawm polysiloxane thiab cov nyhuv polarity ntawm cov pab pawg hloov kho. Ib qho me me ntawm cov tshuaj tuaj yeem txhim kho qhov fluidity thiab processability, txo cov kua qaub ntawm lub cev thaum lub sijhawm extrusion, thiab tshem tawm qhov yaj tawg, siv dav los txhim kho cov roj nplua nyeem thiab cov yam ntxwv ntawm cov yas extrusion, zoo rau ib puag ncig thaum nce kev tsim khoom thiab cov khoom zoo.

Tus yuam sij ntawmSILIKE SILIMER-5090 Cov tshuaj ntxiv uas tsis yog fluoropolymerdaim ntawv thov hauv xov hlau & cable, yeeb nkab, thiab lwm yam kev siv kawg ntau yam thiab.SILIMER-5090 PPA MB uas tsis muaj Fluorine——qhov kev daws teeb meem zoo tshaj plaws rauPFAS thiab lwm yam tshuaj uas tsis muaj fluorine.

NrogSILIKE SILIMER 5090 cov khoom ntxivtxawm tias tsis muaj fluorine, qhov nocov tshuaj ntxiv PFAS tshiab thiab cov tshuaj fluorine tsis muajtswj lossis txhim kho cov yam ntxwv ntawm cov nyom dag. Nws muaj kev ruaj khov thiab UV ruaj khov piv rau cov tshuaj ntxiv PPA ib txwm muaj, cov chaw tsim khoom pab txhawb rau kev tsim cov khoom nyom dag uas muaj kev nyab xeeb dua rau cov neeg siv khoom thiab ib puag ncig!
