Tambayoyi da Amsoshi: Inganta Tsarin Polyamide Mai Ƙarfafawa na PA66 da Glass Fiber
T1: Ta yaya zan iya kawar da "Fiber mai iyo" (farin zare) a saman Fiber ɗin da aka ƙarfafa na Glass PA66?
A: “Fiber mai iyo” yana faruwa ne lokacin da yawan kwararar nailan da zare-zaren gilashi ba su daidaita ba. Yin amfani da SILIKE SILIMER 5150, wani ƙarin silicone da aka gyara, yana inganta daidaito tsakanin fuskoki da daidaiton kwarara. Wannan yana tabbatar da cewa resin PA66 yana lulluɓe zare (30%–50% GF) yadda ya kamata, wanda ke haifar da santsi da kamanni na saman ba tare da zare-zaren da ake gani ba.

T2: Menene hanya mafi kyau don rage matsin lamba na fitarwa da inganta kwararar narkewa a cikin samar da PA66?
A: Yawan danko na narkewa a cikin PA66 sau da yawa yana haifar da matsin lamba mai yawa na fitarwa da lalacewa na kayan aiki. SILIKE Silicone Masterbatch LYSI-407 da SILIMER 5150 suna aiki azaman man shafawa na ciki da waje masu inganci. Suna rage danko na narkewa da karfin juyi na extruder sosai, wanda ke ba da damar rage yanayin zafi na sarrafawa, rage yawan amfani da makamashi, da kuma yawan samar da kayayyaki.

T3: Shin kayan sarrafawa na iya inganta ingancin saman PA66 ba tare da rasa hasken gani ba?
A: Eh. Duk da cewa kakin zuma na gargajiya na iya haifar da gajimare ko "hazo," an tsara SILIKE SILIMER 5150 musamman don polyamides masu haske. Yana rage lahani a saman fata kamar "sharkskin" da taruwar mutu yayin da yake kiyaye tsabtar gani da bayyananniyar da ake buƙata don rufin waya da kebul na zamani da kuma abubuwan da ke cikin PA66 masu haske.
