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

Ukuqhekeka kwe-melt yenye yezona ziphene zixhaphakileyo kumphezulu kwi-polyethylene (PE) film extrusion, ingakumbi kwi-LLDPE, HDPE, kunye ne-mLLDPE high-speed processing.

Ngokwesiqhelo ibonakala ngolu hlobo:

• Ubume bomphezulu wesikhumba seSharks

• Imbonakalo yefilimu erhabaxa okanye engaqhelekanga

• Ukungazinzi kokuhamba kwamanzi kwindawo yokuphuma

• Ukulahleka kokukhanya okucacileyo

Unobangela weengcambu

Ukuqhekeka kokunyibilika kubangelwa kukungahlaliseki kokuhamba kobuso xa i-polymer melt idlula kwi-die phantsi koxinzelelo olukhulu lokucheba.

Xa uxinzelelo lokucheba ludlula umda obalulekileyo:

• Ukunyibilika kwepolymer akukwazi ukugcina ukuhamba kakuhle

• Ukuziphatha kokutyibilika kweenduku kwenzeka eludongeni lwedayi

• Umaleko womphezulu uyaqhekeka rhoqo

Oku kuba nzima ngakumbi xa kujongwa oku kulandelayo:

• Ukukhupha isantya esiphezulu

• Izikhewu ezimxinwa zokudaya

• Iiresini ezinobunzima obukhulu beemolekyuli

• Amanqanaba e-PE asekelwe kwi-Metallocene

Kutheni kusetyenziswa ii-PPA ze-fluoropolymer zemveli

Kangangamashumi eminyaka, ii-Polymer Processing Aids (PPAs) ezisekelwe kwi-fluoropolymer bezisetyenziswa ukusombulula iingxaki zokuqhekeka kwe-melt kwi-PE film extrusion.

Basebenza ngolu hlobo:

• Ukufudukela kumphezulu wedayi

• Ukwenza ulwelo olune-fluorine olunamandla aphantsi

• Ukunciphisa ukungqubana kwe-melt-die

• Ukuvumela ukutyibilika eludongeni

Oku kunceda ukuzinzisa ukuhamba kwamanzi anyibilikayo nokususa iziphene zesikhumba sooshaka.

Nangona kunjalo, uxinzelelo olukhulayo lolawulo kwizinto ezinxulumene nePFAS lutshintsha indlela abaprosesa abajongana ngayo nesi sisombululo.

Kutheni abavelisi befuna izisombululo ezingezizo ze-fluoropolymer

Ngenxa yoko, abaprosesa bafuna ngenkuthalo:

Indlela yokuphelisa ukwaphuka kwe-melt ngaphandle kwe-fluoropolymers

Ngaba ukuqhekeka okunyibilikisiweyo kunokususwa ngaphandle kwe-fluoropolymers?

Ewe.

Uninzi lwabavelisi bezongezo zepolymer baqalise izixhobo zokulungisa ezingenayo iPFAS, bebonelela ngendlela eyahlukileyo engaxhomekekanga kwiingubo zomphezulu ezine-fluorine.

Endaweni yokwenza ifilimu ye-fluoropolymer esisigxina, ezi nkqubo zisebenza ngolawulo lokuthambisa olutshintshatshintshayo phakathi kwe-interfacial.

Indlela i-PFAS-free processing enceda ngayo ukuphelisa ukuqhekeka kwe-melt

Ii-PPA ezingenayo i-PFAS (ingakumbi iinkqubo ezisekwe kwi-silicone) zinciphisa ukwaphuka kwe-melt ngokusebenzisa indlela eyahlukileyo:

1. Uzinzo lokutyibilika kobuso

Zitshintsha indlela ezisebenzisana ngayo umphezulu we-polymer melt kunye ne-die, nto leyo enciphisa ukungazinzi kwe-stick-slip.

2. Ukunciphisa ukuguquguquka koxinzelelo lokucheba

Ngokulungisa indlela esebenza ngayo i-flow kwinqanaba le-molecular, zinciphisa utshintsho olukhawulezileyo loxinzelelo ekuphumeni kwe-die.

3. Ukwakheka komaleko wokuthambisa okuguqukayo

Umaleko wemolekyuli ozilungisa ngokwawo uyenzeka kwindawo edibanisa izinto, nto leyo ehlala izinzisa iimeko zokukhupha izinto.

4. Ukuphuculwa kokufana kokuhamba kokunyibilika

Ukunyibilika kwepolymer kugcina iprofayili yesantya esihambelanayo kwidayi.
