Halbeegyada farsamada ee masterbatch silikoon ganacsi waa inay ku jiraan waxyaabaha soo socda:

(1) Marka loo shaqeeyo sidii saliid ama beddele rheological, nuxurku wuxuu u dhexeeyaa 5 ilaa 50%

(2) Qaade waa in uu la jaan qaada silikoon waana in la tixgaliya substrate-ka ugu weyn ee isticmaalaha, oo leh calaamadda magaca polymer iyo tusmada dhalaalaysa side, si ay isticmaalayaashu u tixraacaan marka ay naqshadeynayaan caanaha. Haddii budada macdanta aan organic loo isticmaalo sida gudbiyaha, magaca budada waa in la tilmaamaa. Cadaannimada iyo fayoobaanta budada aan organic ahayn ayaa muhiim u ah macaamiisha, iyo budo cad iyo mikron ah waa in loo doortaa sida ugu macquulsan ee wax soo saarka.

 

Markaad u shaqeyso sidii saliidaha ama beddelayaasha rheological

Wixii maaddada Polyethylene

Sida la wada ogsoon yahay, ifafaalaha "maqaarka shark" wuxuu badanaa dhacaa marka la sii daayo fiilooyinka polyetylen-ka-dahaaran ama fiilooyinka, gaar ahaan marka la sii daayo polyetylen cufnaanta hoose (LLDPE) ama cufnaanta ultra-hoose ee polyetylen (ULDPE ama POE). Walxaha polyetylenka ee iskutallaabta ah ee la sii daayay (haddii ay tahay isku-xidhka-isku-xidhka peroxide ama isku-xidhka-isku-xidhka silane) ayaa sidoo kale mararka qaarkood la kulma ifafaale "maqaarka shark", taas oo ay ugu wacan tahay tixgalinta ku filan ee nidaamka sifaynta ee qaacidada walxaha. Dhaqanka caalamiga ah ee hadda jira waa in lagu daro cadadka fluoropolymers ee caanaha caanaha, laakiin qiimuhu waa sarreeyaa codsigana wuu xadidan yahay.

Iyada oo qadar yar oo ahSilikoon miisaankeedu aad u sareeyo(0.1-0.2%) ilaa polyetylen ama polyetylen isku-tallaabta waxay si wax ku ool ah uga hortagi kartaa jiilka "maqaarka shark". Isla mar ahaantaana, oo leh saameynteeda saliideed, waxay si wax ku ool ah u yareyn kartaa qulqulka qulqulka si looga hortago in matoorka jiidaya uu istaago sababtoo ah culeyska xad-dhaafka ah.

Silikoon loo isticmaalo saliid ahaan, sababtoo ah ku darida ugu yar, waa in si siman loogu qaybiyaa walxaha si ay u shaqeyso inta lagu jiro habka. Sababo la xiriira la'aanta kiimikada ee silikoon, kama falcelin doonto kiimikaad qaybaha ku jira caanaha. Waxaa lagu talinayaa in warshadda walxaha fiilada ay si siman ugu daraan silikoon habka granulation plasticizing si loo fududeeyo isticmaalka warshadda fiilada.

 

WaayoIskudhisyada fiilada ee Halogen free flame retardent(HFFR). 

Sababtoo ah joogitaanka xaddi badan oo dab-demis ah (budada macdanta) ee xeryahooda fiilada HFFR, taas oo keenta viscosity sare iyo socodka liidata inta lagu jiro habka; Viscosity-ka sare wuxuu ka dhigayaa mid adag in matoorku uu jiido xilliga extrusion, iyo dheecaanka liidata wuxuu keenaa qadar yar oo xabag ah oo la soo saaro inta lagu jiro extrusion. Marka, marka warshadda fiilada ay soo saarto fiilooyinka halogen-la'aanta ah, waxtarku waa kaliya 1 / 2-1 / 3 ee fiilada polyvinyl chloride.

Iyada oo qadar gaar ah oo silikoon ah oo qaacidadu ku jirto, ma aha oo kaliya ka shaqaynta sida socodka socodka oo kale laakiin sidoo kale hel dib u dhac olol oo ka fiican alaabta.
