Budada polymer redispersible (RDP) waa isku dhafka adag ee polymers iyo wax lagu daro kuwaas oo si weyn loogu isticmaalo qalabka dhismaha, gaar ahaan soo saarida hoobiye-isku-darka qalalan. Budadani waxay door muhiim ah ka ciyaaraan hagaajinta waxqabadka iyo sifooyinka qalabka dhismaha ee kala duwan sida xabagta dhoobada, grouts, xeryahooda is-miidaminta iyo balastarrada sibidhka.
Qaybaha muhiimka ah:
Saldhig Polymer:
Ethylene vinyl acetate (EVA): EVA copolymer waxaa si caadi ah loogu isticmaalaa RDP sababtoo ah sifooyinka filim samaynta ee aadka u fiican, adhesion, iyo dabacsanaan. Maaddada vinyl acetate ee ku jirta kopolymerka waa la hagaajin karaa si loo beddelo sifooyinka polymerka.
Vinyl Acetate vs. Ethylene Carbonate: Iyadoo ku xiran shuruudaha gaarka ah ee codsiga, soosaarayaashu waxay isticmaali karaan ethylene carbonate halkii ay ka isticmaali lahaayeen vinyl acetate. Ethylene carbonate waxay wanaajisay iska caabinta biyaha iyo ku dhejinta xaaladaha qoyan.
Acrylics: polymers Acrylic, oo ay ku jiraan acrylics saafi ah ama copolymers, ayaa loo isticmaalaa iska caabin cimilo oo gaar ah, adkeysigooda, iyo badiyaa. Waxay caan ku yihiin bixinta adhesion heer sare ah oo kala duwan oo substrates ah.
Colloid difaac:
Hydroxypropyl methylcellulose (HPMC): HPMC waa kolloid ilaalin ah oo caadi ahaan loo isticmaalo RDP. Waxay wanaajisaa kala qaybinta qaybaha polymer-ka waxayna wanaajisaa sifooyinka guud ee budada.
Khamriga Polyvinyl (PVA): PVA waa kolloid kale oo ilaalin ah kaas oo ka caawiya xasilloonida iyo kala firdhinta walxaha polymer. Waxa kale oo ay door ka ciyaartaa xakamaynta viscosity ee budada.
caagadaha:
Dibutyl Phthalate (DBP): DBP waa tusaale balaastig ah oo inta badan lagu daro RDP si loo hagaajiyo dabacsanaanta iyo socodsiinta. Waxay ka caawisaa hoos u dhigista heerkulka kala-guurka dhalada ee polymer-ka, taasoo ka dhigaysa mid aad u jilicsan.
buuxinta:
Calcium Carbonate: Buuxiyeyaasha sida kaarboonaytka kaalshiyamka ayaa lagu dari karaa si kor loogu qaado budada badankeeda oo ay bixiso hab kharash-ku-ool ah oo lagu hagaajinayo sifooyinka sida texture, porosity iyo opacity.
Xasijiyeyaasha iyo antioxidants:
Xasijiyeyaasha: Kuwaas waxaa loo isticmaalaa si looga hortago xaalufka polymerka inta lagu jiro kaydinta iyo habaynta.
Antioxidants: Antioxidants ayaa ka ilaaliya polymer-ka hoos u dhaca oksaydhiyeyaasha, iyaga oo hubinaya cimriga dheer ee RDP.
Hawlaha qayb kasta:
Saldhig Polymer: Waxay siisaa sifooyinka filim-samaynta, dhejinta, dabacsanaanta iyo xoogga farsamada ee alaabta ugu dambeysa.
Colloid ka hortag ah: Kor u kala firdhinta, xasiloonida iyo kala firdhinta walxaha polymerka.
Plasticizer: Waxay wanaajisaa dabacsanaanta iyo socodsiinta
Buuxiyeyaasha: Hagaajin guryaha sida texture, porosity, iyo indho-furnaan.
Xasijiyeyaasha iyo antioxidants: Kahortagga xaalufka polymer inta lagu jiro kaydinta iyo habaynta.
Gabagabadii:
Budada polymer dib loo cusboonaysiin karo (RDP) waa shay la taaban karo oo muhiim u ah qalabka dhismaha ee casriga ah. Qalabkeeda kiimikaad, oo ay ku jiraan polymers sida EVA ama resins acrylic, colloids-ka ilaaliya, balaastikada, buuxinta, xasiliyayaasha iyo antioxidants, ayaa si taxadar leh loo qaabeeyey si loo buuxiyo shuruudaha gaarka ah ee codsi kasta. Isku darka qaybahani waxay gacan ka geystaan hagaajinta dib-u-celinta budada, xoogga dammaanadda, dabacsanaanta iyo waxqabadka guud ee hababka qallalan ee isku dhafka ah ee hoobiyeyaasha.
