Ukutshintshwa kweFluoropolymer kwiNkqubo yeFilimu eZinzileyo nekhawulezayo

Ziziphi iingxaki ezithintela ukukhutshwa kwefilimu ye-PE namhlanje?

Ukukhutshwa kwefilimu yePolyethylene (PE) kusetyenziswa i-LLDPE, i-HDPE, kunye ne-MLLDPE kudla ngokuthintelwa kukuqhekeka kwe-melt, ukwakheka kwesikhumba se-sharks, kunye nokuhamba kwe-die okungazinzanga phantsi kweemeko eziphezulu.

Ezi ziphene zibangelwa kukungazinzi kokungqubana phakathi kwe-polymer melt kunye nomphezulu we-metal die, ingakumbi xa kukho uxinzelelo oluphezulu lwe-shear.

Ii-PPA ezisekelwe kwi-Fluoropolymer bezisoloko zisetyenziswa ukuzinzisa ukucubungula, kodwa ukunyuka koxinzelelo lolawulo lwe-PFAS kukhawulezisa utshintsho oluya kwezinye iindlela ezingena-fluorine.

Kutheni ukuqhekeka kwe-melt kwenzeka kwi-PE film extrusion?

Ukuqhekeka kokunyibilika kwenzeka xa ukuhamba kokunyibilika kwepolymer kutshintsha ukusuka kwi-stable shear ukuya kwi-stick-slip instability emva kokudlula uxinzelelo olubalulekileyo lwe-shear ekuphumeni kwedayi.

Oku kuphazamisa ukuqhubeka komaleko onyibilikayo kumphezulu we-die, nto leyo ebangela iziphene zesikhumba se-shark kunye ne-evenly film morphology.

Umngcipheko uyanda ngesantya esiphezulu somgca, izithuba ezincinci zokudaya, ii-resin ezinobunzima obukhulu beemolekyuli, kunye nee-polyethylene ezisekwe kwi-metallocene.

Kutheni ii-PPA ze-fluoropolymer zitshintshwa?

Ii-PPA zeFluoropolymer zisebenza ngokufudukela kumphezulu we-die kwaye zenze umaleko wokuthambisa ongenamandla aphantsi onciphisa ukungqubana kwaye uzinzise ukuhamba kwe-melt.

Nangona kunjalo, ukuqhubeka kwabo nokusingqongileyo njengezinto ezinxulumene nePFAS kuqhuba imiqathango yokulawula kwi-EU, eMntla Melika, nakwezinye iindawo.

Ngenxa yoko, abavelisi beefilimu batshintshela kwiinkqubo zokucubungula ezingasebenzisi i-fluorinated ezigcina:

• Uzinzo lwesantya esiphezulu

• Inkungu ephantsi kunye nokukhazimla okuphezulu

• Ukucoceka kwexesha elide

• Ukuthobela imithetho

Ii-PPA ezingenayo i-PFAS ziphelisa njani ukuqhekeka kwe-melt?

Ii-PPA ezingenayo i-PFAS zinciphisa ukwaphuka kwe-melt ngokuguqula i-interfacial dynamics phakathi kwe-polymer melt kunye ne-die surface endaweni yokuxhomekeka ekunciphiseni amandla omphezulu we-fluorinated.

Benza umaleko wokuthambisa wemolekyuli olawulwayo ngokusebenzisana ne-metal interface kunye ne-polymer matrix, beqinisa iimeko zokutyibilika ngexesha lokuphuma.

Le ndlela ithintela ukungazinzi kwe-stick-slip, inciphisa ukuguquguquka koxinzelelo lwe-shear, kwaye iphucula ukufana komphezulu xa umbane uphuma kakhulu.

• Amacandelo e-polar

Sebenzisana nemiphezulu yesinyithi (isikrufu, ibhere, idayisi) kwaye wenze umaleko wokuthambisa ozinzileyo phakathi kobuso onciphisa ukunamathelana kokunyibilika kunye nokuthintela ukwakheka kwedayi.

• Umqolo wePolysiloxane

Ibonelela ngokungqubana okuphantsi kakhulu kunye nozinzo oluphezulu lobushushu, iphucula indlela yokuhamba kokunyibilika phantsi koxinzelelo lokucubungula.

•Iitsheyini zehydrocarbon ezingezizo ezomhlaba

Qinisekisa ukuba iyahambelana ne-PE/PP matrices kwaye wenze ukuba kubekho ukusasazwa okufanayo kunye nokufuduka okulawulwayo ngexesha lokukhupha.

Olu lwakhiwo lwenza kube lula ukwakheka komaleko wokuthambisa oguqukayo, ozihlaziyayo othatha indawo yeendlela zokuguqula umphezulu ezisekelwe kwi-fluoropolymer.
