Izindaba

I-Silicone masterbatchluhlobo lwesengezo embonini yenjoloba neyepulasitiki. Ubuchwepheshe obuthuthukisiwe emkhakheni wezithasiselo ze-silicone ukusetshenziswa kwe-ultra-high molecular weight (UHMW) silicone polymer (PDMS) kuma-resin ahlukahlukene we-thermoplastic, njenge-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, njll. Futhi njengama-pellets ukuze uvumele ukungezwa kalula kwesithasiselo ngqo ku-thermoplastic ngesikhathi sokucubungula. ukuhlanganisa ukucubungula okuhle kakhulu nezindleko ezingabizi. I-silicone masterbatch kulula ukuphakela, noma ukuyixuba, ibe amapulasitiki ngesikhathi sokuhlanganisa, ukusikhipha, noma ukubumba umjovo. Kungcono kunamafutha we-wax wendabuko kanye nezinye izithasiselo ekuthuthukiseni ukushelela ngesikhathi sokukhiqiza. Ngakho-ke, amaprosesa epulasitiki akhetha ukuwasebenzisa ekuphumeni.

Izindima zeIsengezo se-Silicone MasterbatchEkuthuthukiseni Ukucubungula Kwepulasitiki

I-silicone masterbatch ingenye yezinketho ezidume kakhulu zamaphrosesa ekucutshungulweni kwepulasitiki kanye nokuthuthukiswa kwekhwalithi yendawo. Njengohlobo lwe-super lubricant. Inemisebenzi esemqoka elandelayo lapho isetshenziswa ku-thermoplastic resin:

A. Thuthukisa ukuhamba kwe-resin nokucubungula;

Izakhiwo ezingcono zokugcwalisa isikhunta kanye nezakhiwo zokukhulula isikhunta

Yehlisa i-torque ye-extrude futhi uthuthukise izinga lokukhipha;

B. Ithuthukisa izakhiwo ze-resin

Thuthukisa i-plastic surface finish, i-degree ebushelelezi, futhi unciphise i-coefficient ye-skiction yesikhumba, Thuthukisa ukumelana nokugqokwa nokumelana nokunwaya;

Futhi i-silicone masterbatch inokusimama okuhle kokushisa (izinga lokushisa lokubola okushisayo lingaba ngu-430 ℃ ku-nitrogen) nokungafuduki;

Ukuvikelwa kwemvelo;

Ukuthintana ngokuphepha nokudla.

Kufanele siveze ukuthi yonke imisebenzi ye-silicone masterbatches ingeye-A no-B (la maphuzu amabili angenhla esiwabalile) kodwa akuwona amaphuzu amabili azimele kodwa

bayenezelana, futhi bahlobene eduze.

Imithelela emikhiqizweni yokugcina

Ngenxa yezici zesakhiwo samangqamuzana e-siloxane, umthamo mncane kakhulu ngakho-ke cishe awukho umthelela endaweni eyimishini yemikhiqizo yokugcina. uma sikhuluma nje, ngaphandle kobude namandla okuthinta kuzokwenyuka kancane, kungabi namiphumela kwezinye izakhiwo zemishini. Ngesilinganiso esikhulu, sinomphumela we-synergistic nama-ejenti okubuyisela amalangabi.

Ngenxa yokusebenza kwayo okuvelele ekumelaneni nokushisa okuphezulu nokuphansi, ngeke kube nemiphumela emibi ekuphikisaneni okuphezulu nokushisa okuphansi kwemikhiqizo yokugcina. kuyilapho ukugeleza kwe-resin, ukucubungula, kanye nezakhiwo ezingaphezulu kuzothuthukiswa ngokusobala futhi i-COF izoncishiswa.

Indlela yokwenza

Ama-Silicone masterbatchesi-polysiloxane enesisindo esiphezulu kakhulu samangqamuzana ahlakazeke kuma-resin okuthwala ahlukene okuwuhlobo lomsebenzi we-masterbatch. Lapho ultra-high isisindo samangqamuzanaama-silicone masterbatcheszengezwe kumapulasitiki ngenxa ye-nonpolar futhi enamandla aphansi angaphezulu, inomkhuba wokuthuthela endaweni yepulasitiki ngesikhathi sokuncibilika; kuyilapho, njengoba inesisindo esikhulu samangqamuzana, ayikwazi ukuphuma ngokuphelele. Ngakho sikubiza ngokuzwana nobumbano phakathi kokufuduka nokungafuduki. ngenxa yalesi sakhiwo, ungqimba oluguquguqukayo lokuthambisa lwakhiwe phakathi kwendawo yepulasitiki nesikulufu.

Ngokuqhubeka kokucubungula, lesi singqimba sokugcoba sithathwa njalo futhi sikhiqizwa. Ngakho-ke ukugeleza kwe-resin nokucubungula kuyathuthuka njalo futhi kunciphisa amandla kagesi, i-torque yemishini futhi kuthuthukisa okukhiphayo. Ngemuva kokucutshungulwa kwe-twin-screw, ama-silicone masterbatches azosatshalaliswa ngokulinganayo kumapulasitiki bese kwakheka inhlayiya kawoyela eyi-1 kuya ku-2-micron ngaphansi kwesibonakhulu, lezo zinhlayiya zikawoyela zizonikeza imikhiqizo ukubukeka okungcono, umuzwa omuhle wesandla, i-COF ephansi, nangaphezulu. ukumelana nemihuzuko kanye nokuklwebheka.

Kusukela esithombeni singabona ukuthi i-silicone izoba izinhlayiya ezincane ngemva kokuhlakazeka kumapulasitiki, into eyodwa okudingeka siyibonise ukuthi i-dispersibility iyinkomba eyinhloko yama-silicone masterbatches, izinhlayiya ezincane, ezisakazwa ngokulinganayo, umphumela ongcono. sizothola.
