Iindaba

Ii-polymer matrix composites eziqiniswe ngefayibha yeglasi zizinto ezibalulekileyo zobunjineli, zezona zi-composites zisetyenziswa kakhulu kwihlabathi liphela, ikakhulu ngenxa yokonga ubunzima bazo xa zidibene nokuqina kunye namandla athile.

I-Polyamide 6 (PA6) ene-30% yeGlass Fibre (GF) yenye yeepolymers ezisetyenziswa kakhulu ngenxa yeenzuzo ezizisayo ezifana nomgangatho, iimpawu zoomatshini eziphuculweyo, ubushushu obuphezulu bokusebenza, amandla okukrala, ukuphinda kusetyenziswe, kunye nezinye. Zibonelela ngezixhobo ezifanelekileyo zokucubungula amaqokobhe ezixhobo zombane, izixhobo zombane, izixhobo zoomatshini bobunjineli, kunye nezixhobo zeemoto.

Nangona kunjalo, ezi zinto zineengxaki, ezifana neendlela zokucubungula ezidla ngokuba kukubumba ngenaliti. Ukutyibilika kwe-nylon eqiniswe ngentambo akunamsebenzi, nto leyo ekhokelela kuxinzelelo oluphezulu lokujova, ubushushu obuphezulu bokujova, ukujova okunganelisiyo, kunye namabala amhlophe avela kumphezulu, Le nto yaziwa ngokuba yi-"floating fiber", engamkelekanga kwiindawo zeplastiki ezineemfuno eziphezulu kwinkqubo yokubumba ngenaliti.

Ngelixa, kwinkqubo yokuvelisa iimveliso ezibunjiweyo ngenaliti, ii-lubricants azinakongezwa ngokuthe ngqo ukusombulula ingxaki, kwaye ngokubanzi, kuyimfuneko ukongeza ii-lubricants kwifomula eguquliweyo kwizinto eziluhlaza ukuqinisekisa ukuba uqinisekiso lwefayibha yeglasi lufakwe kakuhle kwi-molding.

Isongezelelo se-siliconeisetyenziswa njengesixhobo sokuncedisa ekucubunguleni nasekuthambiseni. Isithako sayo esisebenzayo se-silicone siphucula ukusasazwa kwe-filler kwiifomyula ezizalisiweyo kunye neempawu zokuhamba kwe-polymer melt. Oku kwandisa ukudlula kwe-extruder. Ikwanciphisa amandla afunekayo ekudibaniseni, Ngokubanzi, umthamo we-silicone additive yi-1 ukuya kwi-2 yepesenti. Imveliso kulula ukuyityisa ngenkqubo eqhelekileyo kwaye ifakwe ngokulula kwimixube ye-polymer kwi-extruder enezikrufu ezimbini.

Ukusetyenziswa kweisongezo se-siliconekwi-PA 6 ene-30% yefayibha yeglasi ifunyenwe iluncedo kwiindlela ezahlukeneyo zokusebenza. Ngokunciphisa ubungakanani befayibha etyhilwa kumphezulu wezinto, izongezo ze-silicone zinokunceda ukudala ukugqitywa okuthambileyo kunye nokuphucula ukuhamba kwamanzi. Ukongeza, zinokunceda ekunciphiseni ukugoba kunye nokuncipha ngexesha lokwenziwa kunye nokunciphisa ingxolo kunye nokungcangcazela ngexesha lokusebenza. Ngoko ke,izongezo ze-siliconeyindlela esebenzayo kubavelisi abafuna ukuphucula iimveliso zabo.

Ukuphuhlisa amaqhinga okunciphisa ukuvezwa kwefiber yeglasi yePolyamide 6 PA6 GF30

I-SILIKE Silicone MasterbatchI-LYSI-407 isetyenziswa kakhulu njengesongezo esisebenzayo kwiinkqubo ze-resin ezihambelana ne-PA6 ukuphucula iipropati zokucubungula kunye nomgangatho womphezulu, ezifana nokukwazi ukuhamba kwe-resin okungcono, ukuzaliswa kunye nokukhululwa kwesikhunta, i-torque encinci yokukhupha, i-coefficient ephantsi yokungqubana, ukumelana okukhulu kwe-mar kunye nokukrala.Into enye ekufuneka iqatshelwe inceda ekusombululeni iingxaki zokuchatshazelwa yi-Glass fiber kwi-PA6 GF 30 injection molding.
