Silicone processing aid SC 920 waa gargaar farsamayn silikoon gaar ah oo loogu talagalay LSZH iyo qalabka fiilada HFFR kaas oo ka kooban kooxo gaar ah oo shaqeynaya oo ah polyolefins iyo co-polysiloxane. Polysiloxane ee alaabtani waxay ka ciyaari kartaa doorka soo dejinta ee substrate ka dib beddelka copolymerization, si waafaqsanaanta substrate-ka ay u fiican tahay, wayna fududahay in la kala firdhiyo, iyo xoogga xiritaanka ayaa ka xoog badan, ka dibna siiya substrate waxqabad aad u fiican. Waxaa lagu dabaqaa si loo hagaajiyo waxqabadka qalabka ee nidaamka LSZH iyo HFFR, waxayna ku habboon tahay fiilooyinka xawaaraha sare leh, hagaajinta wax soo saarka, iyo ka hortagga ifafaalaha extrusion sida dhexroorka siligga aan degganeyn iyo silbashada furka.

1, Marka lagu dabaqo nidaamka LSZH iyo HFFR, waxay hagaajin kartaa habka extrusion ee afka ee raasamaal dhinta, ku haboon extrusion-xawaaraha sare ee fiilada, hagaajinta wax soo saarka, ka hortagga dhexroorka xasiloonida line, silbasho iyo ifafaale kale extrusion.
2, Si weyn u wanaajiso flowability processing, yareeyaan viscosity dhalaali in habka wax soo saarka ee-buuxsan sare-buuxiyey halogen-free olol-retardant, la yareeyo torque iyo processing hadda, la yareeyo xirashada qalabka, la yareeyo heerka cillad alaabta.
3, Yaree raasamaal ee madaxa dhinta, la yareeyo heerkulka processing, baabi'iyo dilaaca dhalaalay iyo kala-goynta alaabta ceeriin ay sababto heerkulka processing sare, ka dhigi dusha sare ee silig extruded iyo fiilada siman oo dhalaalaya, la yareeyo coefficient khilaaf ee dusha badeecada, wanaajiso waxqabadka siman, wanaaji dhalaalka dusha sare, siin dareen siman, hagaajinta caabbinta xoqan.
4, Iyada oo silikoon silikoon ah oo khaas ah oo wax laga beddelay sida walxaha firfircoon, hagaajinta kala firdhisanaanta ololka ee nidaamka, siiya xasilooni wanaagsan iyo guuritaan la'aan.
Ka dib marka la isku daro SC 920 iyo xabagta saami ahaan, si toos ah ayaa loo samayn karaa ama loo isticmaali karaa granulation ka dib. Qadarka dheeriga ah ee lagu taliyay: Marka qadarka lagu daro 0.5%-2.0%, waxay hagaajin kartaa habka socodka, dareeraha iyo sii deynta alaabta; Marka qadarka dheeriga ah uu yahay 1.0% -5.0%, sifooyinka dusha sare ee alaabta waa la wanaajin karaa (dhammaan, dhammayn, caabbinta xoqan, xirashada caabbinta, iwm.)
25Kg / bac, boorso warqad farshaxan ah
Gaadiidka sida kiimiko aan khatar ahayn. Ku kaydi meel qabow oo hawo fiican leh.
Astaamaha asalka ahi waxay ahaanayaan 24 bilood laga bilaabo taariikhda wax soo saarka, haddii lagu hayo kaydinta talada.
