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 alaabta polymer-ka ayaa noqday mid aad iyo aad muhiim u ah, waa si loo gaaro shuruudaha ololka ee balaastigga iyo alaabta caagga ah, la yareeyo wasakhowga boodhka ee ay sababaan ololka ololka, dab-demiska ololka ayaa soo galay, oo wuxuu ka ciyaaraa door lama huraan ah oo muhiim ah naqshadeynta alaabta ugu dambeysa.

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 kaalin 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 ololka, si ay u fududahay in si siman u kala firdhiso in geeddi-socodka, si looga hortago agglomeration ee ololka retardant, ka wanaagsan saamaynta kala firdhiso, si ay u sameeyaan olol retardant retardant halkaas si ay u hagaajiyaan moleculest flame halkaas si ay u ciyaaraan flame retardant. waxtarka caagga ah, alaabta caagga ah, dabka ayaa la ceejin doonaa 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 ololka retardant ama olol dib masterbatch in habka qaabaynta alaabta, la yareeyo dhacdooyinka kala firidhsan sinnayn ay sababto saamaynta ololka aan si hufan loo hawlgelin karaa, iwm, iyo in la wanaajiyo tayada alaabta retardant olol, SILIKE ayaa soo saaray hyperdispers silicone wax ka beddeleen.

SILIMER waa nooc ka mid ah siloxane saddex-block ah oo la beddelay 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, waxay sidoo kale hoos u dhigi kartaa viscosity ee dhalaalidda, yaraynaysaa qulqulka extruder, cadaadiska extrusion, hagaajinta waxqabadka wax soo saarka ee alaabta, oo leh habaysan habaysan wanaagsan, iyo isla mar ahaantaana si wax ku ool ah u wanaajin kartaa dareenka dusha sare ee alaabta, oo leh heer gaar ah oo siman oo aan saameyn ku yeelan sifooyinka farsamo ee alaabta, waa in kor loogu qaado kala firdhisanaanta isku midka ah ee qaybaha ololka - si ay u horumariyaan kala firdhiso alaabta ee fladant. si buuxda u ciyaar xalalka tayada sare 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.
