Sida loo hagaajiyo kala firidhsanaanta ololka

Iyada oo la adeegsanayo isticmaalka ballaaran ee alaabta polymer-ka iyo alaabta macaamiisha elektaroonigga ah ee nolol maalmeedka, dhacdooyinka dabku sidoo kale waa kor u kaca, waxyeelada ay keento waa xitaa cabsi badan. Waxqabadka dab-demiska ee walxaha polymer-ka ayaa noqday mid aad iyo aad muhiim u ah, waa si loo gaaro shuruudaha dib-u-celinta ololka ee balaastigga iyo alaabada caagga ah, la yareeyo wasakhowga boodhka ee uu keeno ololka ololka, dab-demiska ololka ayaa yimid, oo wuxuu ciyaaraa wax aan laga maarmi karin. iyo doorka muhiimka ah ee naqshadeynta alaabta kama dambaysta ah.

Masterbatch ololka retardant waxaa loo sameeyaa si waafaqsan qaacido macquul ah, iyada oo isku darka organic ee olol retardant, firdhiso saliid iyo side, iyada oo sifaynta cufan, qaso, lebbis ka dibna granulation extrusion. In this, kala firdhiyey door aad u muhiim ah, ku dar qayb gaar ah oo kala firdhiyey noqon kartaa mid aad u wanaagsan si kor loogu qaado kala firidhsan ee retardant olol, si ay u fududahay in si siman u kala firdhiso in geeddi-socodka, si looga hortago agglomeration ee ololka retardant, Si ka wanaagsan saamaynta kala firdhiso, si ay u sameeyaan molecules ololka retardant si ay u ciyaaraan saamayn retardant olol ka fiican, taas oo hagaajinaysa hufnaan olol caag ah, alaabta caag ah, dabka la ceejin doonaa in marxaladda hore.

Si kastaba ha ahaatee, ficil ahaan, balaastig iyo qaybo badan oo caag ah oo ay ku jiraan qaybaha ololka ayaa awoodi waayaan inay qabtaan sifooyinkooda ololka sababtoo ah kala firidh la'aanta dabka-dejinta walxaha dabka, taas oo keenta dab weyn iyo khasaare halis ah.

Si kor loogu qaado kala firidhsan dirayska ee retardants olol ama olol dib masterbatch in geeddi-socodka qaabaynta alaabta, la yareeyo dhacdooyinka kala firidhsan sinnayn ay sababto saamaynta ololka aan si hufan u dhaqmeen, iwm, iyo hagaajinta tayada alaabta retardant olol. SILIKE waxay soo saartay wax lagu daro silikoon SILIMER hyperdispersant.

SILIMER waa nooc ka mid ah siloxane la beddelay oo tri-block ah oo ka kooban polysiloxanes, kooxaha polar iyo kooxaha silsiladaha kaarboonka ee dheer. Qaybaha silsiladda polysiloxane waxay ciyaari karaan door go'doon gaar ah oo u dhexeeya molecules ololka ee hoos yimaada xiirta farsamada, iyaga oo ka hortagaya isku-darka labaad ee molecules ololka; Qaybaha silsiladaha kooxda dabaylaha waxay leeyihiin xoogaa ku xidhidhiyaha ololka, iyagoo ciyaaraya doorka isku-xidhka; Qaybaha silsiladda kaarboonka ee dheer waxay leeyihiin iswaafajin aad u wanaagsan oo leh walxaha saldhigga ah.

Badeecooyinkan taxanaha ah waxay ku habboon yihiin resins thermoplastic, TPE, TPU iyo elastomeryada kale ee heerkulbeegga, waxayna hagaajin karaan iswaafajinta u dhexeeya midabada/budada budada ah/budada shaqaynaysa iyo nidaamka resinka, waxayna ilaalin karaan xaalada kala firdhisanaanta budada.

Isla mar ahaantaana, waxa ay sidoo kale hoos u dhigi kartaa viscosity ee dhalaalidda, la yareeyo torque ee extruder ah, cadaadiska extrusion, hagaajinta waxqabadka processing ee wax, oo leh saliid processing wanaagsan, iyo waqti isku mid ah si wax ku ool ah u hagaajin kartaa dareenka dusha sare ee alaabta, oo leh heer gaar ah oo siman oo aan saameyn ku yeelan sifooyinka farsamada ee walxaha, waa in kor loo qaado kala firdhinta isku midka ah ee qaybaha ololka-celinta si kor loogu qaado saameynta ololka ee alaabta kama dambaysta ah si loo siiyo ciyaar buuxda oo sare. -xalalka tayada leh.

Intaa waxaa dheer, taxanahan alaabooyinka ma aha oo kaliya ku haboon ololka masterbatch, laakiin sidoo kale midabka masterbatch ama fiirsashada sare ee alaabta horay loo kala firdhiyey.
