Silicone masterbatchimhando yekuwedzera muindasitiri yerabha nepurasitiki. Tekinoroji yepamusoro mumunda wekuwedzera kwesilicone ndeyekushandisa ultra-high molecular weight (UHMW) silicone polymer (PDMS) mumaresini akasiyana-siyana ethermoplastic, akadai seLDPE, EVA, TPEE, HDPE, ABS, PP, PA6, PET, TPU, HIPS, POM, LLDPE, PC, SAN, nezvimwewo. Uye semapellets kuitira kuti zvive nyore kuwedzera kuwedzera kwekuwedzera zvakananga kuthermoplastic panguva yekugadzirisa. Kusanganisa kugadzirisa kwakanaka nemutengo unokwanisika. Silicone masterbatch iri nyore kuiisa, kana kusanganisa, mumapurasitiki panguva yekubatanidza, extrusion, kana injection molding. Iri nani pane mafuta ewakisi echinyakare nezvimwe zvinowedzera mukuvandudza kutsvedza panguva yekugadzira. Saka, ma processor epurasitiki anosarudza kuashandisa mukubuda.

Mabasa eSilicone Masterbatch chinowedzeramukuvandudza Kugadzirwa kwePurasitiki

Iyo silicone masterbatch ndeimwe yesarudzo dzakakurumbira dzema processors mukugadzirisa mapurasitiki uye kuvandudza kunaka kwenzvimbo. Semhando yemafuta akanakisa. Ine mabasa makuru anotevera kana ikashandiswa mu thermoplastic resin:

A. Kuvandudza kuyerera kweresin nekugadzirisa;

Zviri nani kuzadza chakuvhuvhu uye kuburitsa chakuvhuvhu

Deredza torque yekubuda kwemhepo uye wedzera mwero wekubuda kwemhepo;

B. Inovandudza hunhu hwepamusoro pe resin

Kuvandudza kupenya kwepurasitiki, mwero wakatsetseka, uye kuderedza kukweshana kweganda, Kuvandudza kuramba kwekukwesha uye kuramba kukwesha;

Uye silicone masterbatch ine kugadzikana kwakanaka kwekupisa (kupisa kupisa kuri pamusoro pe430 ℃ munitrogen) uye kusafamba-famba;

Kudzivirirwa kwezvakatipoteredza;

Kubata chikafu zvakachengeteka.

Tinofanira kutaura kuti mabasa ese e silicone masterbatches ndea A na B (mapoinzi maviri ataurwa pamusoro apa) asi haasi mapoinzi maviri akazvimiririra asi

vanobatsirana, uye vane hukama hwepedyo.

Mhedzisiro pazvigadzirwa zvekupedzisira

Nekuda kwehunhu hwemaumbirwo emamorekuru e siloxane, chiyero chacho chidiki kwazvo saka zvese hazvizove nemigumisiro pahunhu hwemuchina hwezvigadzirwa zvekupedzisira. Kazhinji, kunze kwekureba uye simba rekukanganisa zvichawedzera zvishoma, pasina mhedzisiro pane zvimwe hunhu hwemuchina. Pachiyero chikuru, ine simba rekubatana pamwe chete nemishonga inodzivisa moto.

Nekuda kwekushanda kwayo kwakanaka pakudzivirira kupisa kwakanyanya uye kwakaderera, haizovi nemigumisiro yakaipa pakudzivirira kupisa kwakanyanya uye kwakaderera kwezvigadzirwa zvekupedzisira. Ukuwo kuyerera kweresin, kugadzirisa, uye hunhu hwepamusoro zvichavandudzika zviri pachena uye COF ichaderedzwa.

Maitiro ekuita

Silicone masterbatchesipolysiloxane ine huremu hwakawanda kwazvo inoparadzirwa mumaresini akasiyana-siyana anova rudzi rwebasa remasterbatch. Kana iri huremu hwakawanda kwazvo hwemamorekurusilicone masterbatcheszvinowedzerwa mumapurasitiki nekuda kwekusamira kwawo pasi uye nesimba shoma pamusoro, zvine tsika yekufamba kuenda pamusoro pepurasitiki panguva yekunyunguduka; nepo, sezvo iine huremu hwakawanda hwemamorekuru, haigone kubuda zvachose. Saka tinozviti kubatana pakati pekutama nekusatama. nekuda kwehunhu uhwu, denderedzwa rinoshanduka remafuta rakaumbwa pakati pepamusoro pepurasitiki nesikuruu.

Nekuenderera mberi kwekugadzirisa, mafuta aya ari kubviswa uye kugadzirwa nguva dzose. Saka kufamba kwe resin nekugadzirisa kuri kuramba kuchivandudzwa uye kudzikira kwemagetsi, torque yemuchina uye kuvandudza kubuda. Mushure mekugadzirisa twin-screw, silicone masterbatches ichagoverwa zvakaenzana mupurasitiki uye inoumba 1 kusvika 2-micron oil particle pasi pe microscope, mafuta iwayo achapa zvigadzirwa chitarisiko chiri nani, kunzwa kwakanaka kweruoko, COF yakaderera, uye kuramba kukuru kwekukwenya uye kukwenya.

Kubva pamufananidzo tinogona kuona kuti silicone ichava zvidimbu zvidiki mushure mekupararira mumapurasitiki, chimwe chinhu chatinofanira kutaura ndechekuti kupararira kwayo ndiyo inonyanya kukosha pakushandisa silicone masterbatches, kana zvidimbu zvidiki, kana zvakapararira zvakaenzana, ndipo patichawana mhedzisiro iri nani.
