Iindaba

I-Sharkskin (ukuqhekeka kwe-melt) ichaphazela umgangatho kunye nokusebenza kakuhle kwe-polymer extrusion. Funda ngezizathu zayo, izisombululo zemveli, kunye nesizathu sokuba izixhobo zokulungisa i-polymer ezingena-fluorine kunye ne-PFAS ezifana ne-SILIKE SILIMER Polymer Processing Aids ziyindlela ezinzileyo.

Yintoni ukuqhekeka kwesikhumba sesharks okanye umphezulu onyibilikayo ngexesha lokukhutshwa kweepolymers?

I-Sharkskin (ekwaziwa ngokuba yi-surface melt fracture) sisiphene somphezulu esibonwa ngexesha lokukhutshwa kwe-polymer melts, apho i-extrudate ikhula imbonakalo erhabaxa, egobileyo, okanye eqhekekileyo efana nobume besikhumba seshark, ingakumbi kwiinkqubo ezifana nokuvuthuza ifilimu, ukubumba i-extrusion, kunye nokufakelwa kwentambo.

Iphawulwa yi:

Umphezulu orhabaxa, ongacacanga, okanye onamaqhuqhuva kwi-extrudate (i-polymer melting njengoko iphuma kwi-die).

Ijongeka ngathi ifana nolusu lukashaka, apho livela khona eli gama.

Izizathu zesikhumba se-sharks kwi-polymer extrusion

I-Sharkskin luhlobo lokuqhekeka kokunyibilika, okubangelwa kukungazinzi kudonga lwe-polymer-die. Xa ukunyibilika kwe-polymer kuphuma kwi-die, ifumana ukwehla ngequbuliso koxinzelelo kunye nokunyuka okukhulu kwesantya.

Ukuba i-melt inamathela kakhulu eludongeni lwe-die (uxinzelelo oluphezulu lwe-shear eludongeni), umaleko womphezulu uyanwebeka kakhulu. Oku kukhokelela ekuqhekekeni nasekukrazuleni komphezulu we-polymer melt, nto leyo edala ipateni yesikhumba se-sharks.

Iimeko eziqhelekileyo zeSharkskin

Uxinzelelo oluncinci lungaphezulu komda obalulekileyo (ngokuqhelekileyo ~0.1–0.3 MPa, kuxhomekeke kwi-polymer).

Isantya esiphezulu sokukhupha / izinga lokucheba.

Iipolymers ezinobunzima obuphezulu okanye ezinobunzima beemolekyuli eziphezulu zisengozini enkulu, zifumaneka rhoqo kwi-PP kunye neepolymers ezithe ngqo (umz., i-LLDPE,i-mLLDPE) kunakwii-polymers ezinamasebe.

Iziphumo kubavelisi

Umgangatho ophantsi womphezulu weefilimu, amashiti, okanye iingubo.

Iipropati zoomatshini ezinciphileyo (kuba iziphene zinokuba zizinto ezixinzelelayo uxinzelelo).

Iingxaki ngokucaca kokukhanya kunye nobuhle.

Ungayisombulula njani iSharkskin kunye nokuqhekeka kwee-polymer melt extrudates?

Izisombululo kunye nokulinganiselwa kwezongezo zePolymer zendabuko

Ii-PPA zeFluoropolymer bezisetyenziswa ukususela ngeminyaka yoo-1960 ukunciphisa ulusu loshaka. Zisebenza ngokufudukela kumphezulu wokufa ngexesha lokukhutshelwa ngaphandle, ukunciphisa amandla omphezulu kunye nokwenza kube lula ukutyibilika kwepolymer. Nangona zisebenza kakuhle, ezi PPA zisekelwe kwi-PFAS, ziphakamisa iinkxalabo zokusingqongileyo kunye nempilo:

• Ukuhlala emhlabeni nasemanzini

• Ukuqokelelwa kwezinto eziphilayo kunye nokuphazamiseka okunokwenzeka kwe-endocrine

• Ukuhlolwa kwemithetho kwihlabathi liphela

Izisombululo ze-PPA zasimahla ze-SILIKE SILIMER ze-PFAS ze-Smarter, Greener Extrusion

Uthotho lwe-SILIMER luquka uluhlu olubanzi lweIzixhobo zokucubungula i-polymer ezingenayo i-PFAS (ii-PPA)) yenzelwe iimfuno zokuvelisa zanamhlanje:

• Izongezo ezingenayo i-100% ze-PFAS

•Ii-masterbatches ezingena-fluorine

• Ii-PPA ezingenafluorine ezicocekileyo

• Izongezo ezingenayo i-PTFE

Ezi zisombululo zenzelwe ukuphucula ukusebenza kakuhle kokucubungula ngelixa kususwa iingozi ezinxulumene nePFAS.

 Ii-PPA ezingenayo i-SILIKE SILIMER ze-PFAS ziyahambelana neentlobo ngeentlobo zee-polymers kunye neenkqubo zokukhupha, nto leyo ephucula ukucubungula kwi:
