Iindaba

I-Metallocene polyethylene(mPE) luhlobo lwe-polyethylene resin eyenziwe ngesiseko se-metallocene catalysts, ebaluleke kakhulu into entsha yobuchwepheshe kushishino lwepololefin kwiminyaka yakutshanje. Iintlobo zeemveliso ikakhulu ziquka i-metallocene yoxinzelelo oluphantsi loxinzelelo oluphezulu lwe-polyethylene, i-metallocene yoxinaniso oluphezulu loxinzelelo oluphantsi lwe-polyethylene kunye ne-metallocene yomgca yoxinaniso oluphantsi lwe-polyethylene. I-Metallocene i-polyethylene isetyenziswe ngokubanzi kwinkqubo yokubumba i-multilayer co-extrusion blow ngenxa yeempawu zayo ezizodwa kunye nokusebenza kokucubungula, kwaye ithandwa ngamashishini angaphakathi nangaphandle okupakisha kunye nokushicilela.

Iipropati ze-metallocene polyethylene

1. I-Metallocene polyethylene inobude obungcono ngexesha lekhefu kune-polyethylene eqhelekileyo. I-Metallocene polyethylene inamandla empembelelo angcono ngenxa yobunzima bayo beemolekyuli kunye nokusabalalisa okuxineneyo kune-polyethylene eqhelekileyo.

2. Ubushushu obuphantsi bokutywinwa kobushushu kunye namandla aphezulu okutywinwa kobushushu.

3. ngcono ukungafihli kunye nexabiso lenkungu ephantsi.

Ukusetyenziswa kwefilimu ye-Metallocene polyethylene

1. Ukupakishwa kokutya

Ifilimu ye-Metallocene ye-polyethylene inokugqithwa nge-BOPET, i-BOPP, i-BOPA kunye nezinye iifilimu, ezilungele ukupakisha ukutya kwenyama, ukutya okulula, ukutya okufriziwe kunye nezinye iimveliso.

2. Ukupakishwa kweemveliso zezolimo

Ifilimu evuthelweyo ye-metallocene ye-polyethylene eyenziwe ngeendlela ezahlukeneyo zenkqubo yokuthintela umphunga wamanzi ilungile, ngelixa i-oxygen permeability iphezulu, olu phawu luyenza ifaneleke ngokukodwa ukupakishwa kweziqhamo kunye nemifuno. Ukongeza, ifilimu ye-metallocene ye-polyethylene evuthelweyo ineempawu zamandla aphezulu, i-anti-fogging, anti-dripping, ukumelana nokuguga kunye nokubonakala kakuhle.

3. Iingxowa ezinzima

Iingxowa ezinzima zisetyenziselwa ukupakisha imathiriyeli ekrwada yeplastiki, izichumisi, isondlo, irayisi neenkozo. Ukuvela kwe-metallocene polyethylene, iingxowa ezinzima zinokwenza ukutywinwa kokutywinwa, ukuxhathisa umswakama, ukusebenza kwamanzi, ukusebenza okuchasene nokuguga kuphezulu kakhulu, kunye namaqondo okushisa aphezulu akuthambisi i-deformation, ukubanda akuqheli ukuphuka okuphukileyo kweenzuzo.

Ukongezwa kwe-metallocenes ekusetyenzweni kwefilimu kuphucula amandla okuqina kunye nomgangatho wefilimu, kodwa kukwakho imingeni ethile ekuqhubeni, efana ne-viscosity ephezulu ye-metallocenes echaphazela ukusetyenzwa kwe-fluidity kunye nesiganeko sokunyibilika kwemveliso kwinkqubo ye-extrusion. .

Izizathu zokunyibilika kokuqhekeka kwe-metallocene polyethylene ekusetyenzweni kwefilimu kunokubandakanya oku kulandelayo:

1. viscosity ephezulu: i-metallocene i-polyethylene ine-viscosity ephezulu yokunyibilika, engakhokelela ekuncibilikeni kokuqhekeka ngexesha le-extrusion njengoko ukunyibilika kuxhomekeke kwimikhosi ephezulu yokucheba njengoko idlula kwi-orifice die.

2. Ukulawulwa kobushushu obunganelanga: Ukuba iqondo lobushushu lenkqubo liphezulu kakhulu okanye alilingani, oku kunokubangela ukuba izinto zinyibilike ngokugqithisileyo kwezinye iindawo ngelixa zisala zinyangeka kwezinye, kwaye le meko yokunyibilika engalinganiyo inokukhokelela ekuqhekekeni komphezulu wokunyibilika.

3. Phungula ucinzelelo: Kwinkqubo ye-extrusion, inyibilika inokuthi ixhomekeke kuxinzelelo olugqithisileyo lwe-chear kwi-muzzle die, ngakumbi ukuba i-muzzle iyafa ayilungiswanga ngokufanelekileyo okanye isantya sokucubungula sikhawuleza kakhulu, olu xinzelelo luphezulu lwe-shear lunokubangela ukuphuka kwe-nyibilika.

4. Izongezo okanye ii-masterbatches: Izongezo okanye ii-masterbatches ezongeziweyo ngexesha lokucubungula ezingahlakazwanga ngokufanayo zinokuchaphazela iimpawu zokuhamba kwe-melt, ekhokelela ekuncibilikeni kokuqhaqha.

SILIKE PFAS-free PPA SILIMER 9300，Uphuculo lwe-metallocene polyethylene inyibilikisa ukwaphuka

Iimveliso zothotho lwe-SILIMER zii-PFAS-free polymer processing aids (PPA)eziye zaphandwa zaphuhliswa nguChengdu Silike. Olu chungechunge lweemveliso luyi-Pure modified Copolysiloxane, kunye neepropati ze-polysiloxane kunye nempembelelo ye-polar yeqela elilungisiweyo.

I-SILIMER-9300isongezelelo se-silicone equkethe amaqela asebenzayo e-polar, asetyenziswa kwi-PE, i-PP kunye nezinye iiplastiki kunye neemveliso zerabha, inokuphucula kakhulu ukusetyenzwa kunye nokukhululwa, ukunciphisa ukufa kunye nokuphucula iingxaki zokuqhaqha ukunyibilika, ukwenzela ukuba ukunciphisa imveliso kube ngcono.

Ngaxeshanye,SILIMER 9300inesakhiwo esikhethekileyo, ukuhambelana kakuhle kunye ne-matrix resin, akukho mvula, akukho mpembelelo ekubonakaleni kwemveliso kunye nonyango lomhlaba. Kucetyiswa ukuba ihlanjululwe kumxholo othile we-masterbatch kuqala, emva koko isetyenziswe kwiipolymers ze-polyolefin, ukongeza ngokumodareyitha kunokusebenza kakhulu.

YongezaSILIMER 9300Ukuya kwinkqubo, ukuhamba okunyibilikayo, ukuqhubekeka, kunye nokuthambisa kwe-resin kunokuphuculwa ngokufanelekileyo kunye nokuphelisa ukunyibilika kokunyibilika, ukuxhathisa okukhulu kokunxiba, i-coefficient encinci ye-friction, ukwandisa umjikelo wokucoca izixhobo, ukunciphisa ixesha lokuphumla, kunye nemveliso ephezulu kunye nomphezulu wemveliso engcono, ukhetho olugqibeleleyo lokutshintsha iPPA ecocekileyo esekwe kwifluorine.
