I-Silicone masterbatchluhlobo lwesongezo kushishino lwerabha neplastiki. Itekhnoloji ephezulu kwintsimi yezongezo ze-silicone kukusetyenziswa kwe-ultra-high molecular weight (UHMW) i-silicone ye-polymer (PDMS) kwii-resin ezahlukeneyo ze-thermoplastic, ezifana ne-LDPE, i-EVA, i-TPEE, i-HDPE, i-ABS, i-PP, i-PA6, i-PET, i-TPU. , I-HIPS, i-POM, i-LLDPE, i-PC, i-SAN, njl. Kwaye njengeepellets ukwenzela ukuvumela ukongezwa okulula kwesongezo ngokuthe ngqo kwi-thermoplastic ngexesha lokucubungula. ukudibanisa inkqubo egqwesileyo kunye nexabiso elifikelelekayo. I-silicone masterbatch kulula ukuyondla, okanye ukuxuba, kwiiplastiki ngexesha lokudibanisa, ukukhupha, okanye ukubunjwa kwenaliti. Kungcono kuneoli ye-wax yendabuko kunye nezinye izongezo ekuphuculeni i-slippage ngexesha lemveliso. Ke, iiprosesa zeplastiki zikhetha ukuzisebenzisa kwimveliso.

Iindima zeSilicone Masterbatch additiveekuPhuculeni iPlastiki Processing

I-silicone masterbatch yenye yezona zinto zikhethwa kakhulu kwiiprosesa kwiprosesa yeplastiki kunye nokuphuculwa komgangatho womphezulu. Njengohlobo lwe-lubricant ephezulu. Inemisebenzi ephambili elandelayo xa isetyenziswa kwintlaka ye-thermoplastic:

A. Ukuphucula ukuhamba kwe-resin kunye nokulungiswa;

Ukuzaliswa ngcono komngundo kunye neempawu zokukhulula umngundo

Ukunciphisa i-torque ye-extrude kunye nokuphucula izinga lokukhupha;

B. Ukuphucula iimpawu zomphezulu we-resin

Phucula umphezulu weplastiki ukugqiba, idigri egudileyo, kwaye unciphise i-coefficient yolusu, Ukuphucula ukuxhathisa ukunxiba kunye nokuchasana nokukrweleka;

Kwaye i-silicone masterbatch inozinzo oluhle lwe-thermal (iqondo lokushisa lokubola kwe-thermal li malunga ne-430 ℃ kwi-nitrogen) kunye nokungafuduki;

Ukhuseleko lokusingqongileyo;

Ukhuseleko lokuqhagamshelana nokutya.

Kufuneka sibonise ukuba yonke imisebenzi ye-silicone masterbatches iphethwe ngu-A kunye no-B (ezi ngongoma zimbini zingasentla sizidwelisile) kodwa azikho iingongoma ezimbini ezizimeleyo kodwa.

bayancedisana, kwaye bayazalana ngokusondeleyo.

Iziphumo kwiimveliso zokugqibela

Ngenxa yeempawu zesakhiwo semolekyuli ye-siloxane, idosi incinci kakhulu kangangokuba phantse akukho ziphumo kwipropathi yomatshini yeemveliso zokugqibela. ukuthetha ngokubanzi, ngaphandle kobude kunye namandla empembelelo aya kwanda kancinane, ngaphandle kweziphumo kwezinye iipropati zoomatshini. Kwidosi enkulu, inomphumela we-synergistic kunye neearhente zokubuyiswa komlilo.

Ngenxa yokusebenza kwayo okugqwesileyo ekuchaseni okuphezulu kunye nokushisa okuphantsi, akuyi kuba nemiphumo emibi ekuchaseni okuphezulu kunye nokushisa okuphantsi kweemveliso zokugqibela. ngelixa ukuhamba kwe-resin, ukusetyenzwa, kunye neempawu ezingaphezulu ziya kuphuculwa ngokucacileyo kwaye i-COF iya kuncitshiswa.

Indlela yokusebenza

I-Silicone masterbatchesI-polysiloxane ine-ultra-high molecular weight polysiloxane esasazwe kwii-resin zomthuthi ezahlukeneyo eziluhlobo lomsebenzi we-masterbatch. Xa ultra-high ubunzima molekyulii-silicone masterbatcheszongezwa kwiiplastiki ngenxa ye-nonpolar yazo kunye namandla aphantsi komhlaba, inomkhuba wokufudukela kumphezulu weplastiki ngexesha lenkqubo yokunyibilika; ngelixa, ekubeni inobunzima obukhulu bemolekyuli, ayikwazi ukuphuma ngokupheleleyo. Ngoko sikubiza ukuvisisana kunye nobunye phakathi kokufuduka kunye nokungafuduki. ngenxa yale propati, umaleko wokuthambisa oguqukayo owenziwe phakathi komphezulu weplastiki kunye nesikrufu.

Ngokuqhubeka kuqhubeka, lo maleko wokuthambisa uhlala uthathwa kwaye uveliswa. Ke ukuhamba kwe-resin kunye nokulungiswa kuya kuphuculwa rhoqo kwaye kuncitshiswe umsinga wombane, itorque yesixhobo kunye nokuphucula imveliso. Emva kokusetyenzwa kwe-twin-screw, i-silicone masterbatches iya kusasazwa ngokulinganayo kwiiplastiki kwaye yenze i-micron ye-1 ukuya kwi-2-micron isuntswana yeoli phantsi kwe-microscope, loo masuntswana oyile aya kunika iimveliso ukubonakala okungcono, ukuvakalelwa kwesandla esihle, i-COF ephantsi, kunye nangaphezulu. ukuqhawuka kunye nokuxhathisa umkrwelo.

Ukusuka emfanekisweni sinokubona ukuba i-silicone iya kuba ngamasuntswana amancinci emva kokuba isasazwe kwiiplastiki, enye into ekufuneka siyibonise kukuba i-dispersibility isalathiso esibalulekileyo se-silicone masterbatches, amancinci amancinci, asasazwa ngokulinganayo, umphumo ongcono. siya kufumana.
