Iindaba

I-Sharkskin (i-melt fracture) ichaphazela umgangatho we-polymer extrusion kunye nokusebenza kakuhle. Funda oonobangela bayo, izisombululo zemveli, kwaye kutheni i-fluorine kunye ne-PFAS-i-polymer-free processing aids efana ne-SILIKE SILIMER i-Polymer Processing Aids yeyona ndlela ezinzileyo.

Yintoni i-sharkskin okanye i-surface melt fracture ngexesha lokukhupha iipolymers?

I-Sharkskin (ekwaziwa ngokuba yi-surface melt fracture) sisiphene somphezulu esiqatshelwe ngexesha lokukhutshwa kwe-polymer enyibilikayo, apho i-extrudate ivelisa inkangeleko erhabaxa, e-wavy, okanye egobhodlo efana nokubunjwa kwesikhumba sikakrebe. ngakumbi kwiinkqubo ezifana nokuvuthela kwefilimu, ukubumba i-extrusion, kunye nocingo lokutyabeka.

Ibonakaliswa ngu:

Indawo erhabaxa, i-matte, okanye egobileyo kwi-extrudate (ipolymer iyanyibilika njengoko iphuma kwi-die).

Ngandlel’ ithile ikhangeleka ifana nokumila kwesikhumba sikakrebe, kulapho igama livela khona.

Iimbangela ze-sharkskin kwi-polymer extrusion

I-Sharkskin luhlobo lokwaphuka lokunyibilika, okubangelwa kukungazinzi kwi-polymer-die wall interface. Xa i-polymer inyibilika iphuma ekufeni, ifumana ukuhla ngokukhawuleza koxinzelelo kunye nokwanda okukhulu kwesantya.

Ukuba inyibilika inamathela ngamandla kudonga lokufa (uxinzelelo oluphezulu lokucheba udonga), umaleko womphezulu ufumana ukolulwa kakhulu.Oku kukhokelela ekuqhekekeni kwamaxesha kunye nokukrazula komphezulu wepolymer ukunyibilika, okudala ipateni ye-sharkskin.

Iimeko eziqhelekileyo zeSharkskin

Uxinzelelo lwe-shear ngaphezu komda obalulekileyo (kaninzi ~ 0.1-0.3 MPa, ngokuxhomekeke kwipolymer).

Isantya esiphezulu se-extrusion / izinga lokucheba.

I-high-viscosity okanye iipolima ezinobunzima obuphezulu bemolekyuli zichaphazeleka ngakumbi, zenzeka rhoqo kwi-PP kunye neepolymers ezinomgca (umz., LLDPE,mLLDPE) kuneepholima ezinamagatsha.

Iziphumo zabavelisi

Umgangatho ophantsi wefilimu, amashiti, okanye iingubo.

Iipropathi ezincitshisiweyo zomatshini (kuba iziphene zinokugxininiswa koxinzelelo).

Iingxaki ezicacileyo kunye ne-aesthetics.

Uzisombulula njani iiSharkskin kunye nokuqhekeka kwe-polymer melt extrudates?

Izisombululo zezongezo zePolymer zesiNtu kunye neMida

IiPPA zeFluoropolymer zisetyenziswe ukususela ngo-1960 ukunciphisa i-sharkskin. Basebenza ngokufudukela kumphezulu wokufa ngexesha lokukhupha, ukuthoba amandla angaphezulu kunye nokuququzelela ukutyibilika kwepolymer. Ngelixa zisebenza, ezi PPA zisekwe kwiPFAS, ziphakamisa iinkxalabo zokusingqongileyo kunye nempilo:

• Ukuzingisa emhlabeni nasemanzini

• Ukuqokelelwa kwezinto eziphilayo kunye nokuphazamiseka okunokwenzeka kwe-endocrine

• Uqwalaselo lolawulo kwihlabathi jikelele

Ukunyuka kwePFAS-Izincedisi zokuLungisa iiPolymer zasimahla: Ikamva leZisombululo eziZinzileyo ze-Extrusion

I-SILIKE SILIMER PFAS-Izisombululo zePPA zaMahala zoBuchule, ukuHlaza okuHlaza

I-SILIMER Series ibandakanya uluhlu olubanzi lweIi-PFAS-free polymer processing aids (PPAs) yenzelwe iimfuno zale mihla:

• I-100% izongezo zasimahla zePFAS

•Ii-masterbatches ezingenaFluorine

• IiPPA ezimsulwa ezingenafluorine

• izongezo ezingena-PTFE

Ezi zisombululo zenzelwe ukukhulisa ukusebenza kakuhle ngelixa kususwa umngcipheko ohambelana nePFAS.

 I-SILIKE SILIMER PFAS-i-PPAs engenazo ii-PPA ziyahambelana noluhlu olubanzi lweepolymers kunye neenkqubo ze-extrusion, ziphucula ukusetyenzwa kwi:

• Iipololefin kunye neereyikhi zepololefin

• Iifilim ezivuthelweyo, ezisasaziweyo, kunye nezaleko ezininzi

• I-Fiber kunye ne-monofilament extrusion

•Ikhebula kunye ne-extrusion yombhobho

•Masterbatch kunye nokudibanisa izicelo

Nokuba zivelisa iifilim, imibhobho, iintambo, okanye iifayibha, ii-SILIMER PPAs zinceda abavelisi ukuba bafezekise inkqubo egudileyo, imiphezulu engcono, kunye nokuphuculwa kwemveliso.
