Saamaynta isbeddelka budada cinjirka ah ee ku saabsan sifooyinka hoobiye polymer

Beddelka ku jira budada cinjirka ah ayaa saameyn muuqata ku leh xoogga dabacsanaanta ee hoobiye polymer. Marka waxa ku jira budada cinjirka ah ay tahay 3%, 6% iyo 10%, xoogga dabacsanaanta ee ash-metakaolin geopolymer hoobiyaha waxaa lagu kordhin karaa 1.8, 1.9 iyo 2.9 siday u kala horreeyaan. Awoodda duqsiga ash-metakaolin hoobiyeyaasha geopolymer si ay uga hortagto qallafsanaanta waxay kordhisaa kororka maadada budada cinjirka ah. Marka waxa ku jira budada cinjirka ahi ay tahay 3%, 6% iyo 10%, adkaanta dabacsanaanta ee ash-metakaolin geopolymer waxay kordhisaa 0.6, 1.5 iyo 2.2, siday u kala horreeyaan.

Budada Latex waxay si weyn u wanaajisaa dabacsanaanta iyo isku-xidhka xoogga xajinta ee hoobiye sibidhka, taas oo hagaajinaysa dabacsanaanta hoobiye sibidhka iyo kordhinta xoogga xajinta ee aagga interface ee sibidhka hoobiye-shabkad iyo sibidhka hababka guddiga EPS.

Marka saamiga poly-ash-ku yahay 0.3-0.4, dhererka jebinta hoobiyeyaasha sibidhka polymer-la beddelay ayaa ka boodaya wax ka yar 0.5% ilaa ku dhawaad ​​20%, sidaa darteed maaddadu waxay u gudubtaa kala-guurka adkaanta ilaa dabacsanaanta, oo sii kordhinaysa qaddarka Polymer waxay heli kartaa dabacsanaan aad u fiican.

Kordhinta qadarka budada cinjirka ee hoobiye waxay hagaajin kartaa dabacsanaanta. Marka maadada polymerku ay ku dhowdahay 15%, dabacsanaanta hoobiye ayaa si weyn isbeddelaya. Marka nuxurku ka sarreeyo maadadan, dabacsanaanta hoobiye ayaa si weyn u kordheysa kororka maadada budada cinjirka ah.

Iyada oo la isku xirayo awoodda dildilaaca iyo tijaabooyinka qallafsanaanta, waxaa la ogaaday in kororka maadada budada cinjirka ah (laga bilaabo 10% ilaa 16%), dabacsanaanta hoobiye ayaa si tartiib tartiib ah u kordhay, iyo awoodda qulqulka qulqulka firfircoon (7d) waxay ka korodhay 0.19mm ilaa 0.67 mm, halka qallooca dambe (28d) uu ka kordhay 2.5mm ilaa 6.3mm. Isla mar ahaantaana, waxaa sidoo kale la ogaaday in kororka budada cinjirka ah ay wax yar kordhin karto cadaadiska ka-hortagga jeexjeexa ee dusha dambe ee hoobiye, waxayna yareyn kartaa nuugista biyaha ee hoobiye. Kordhinta maadada budada cinjirka ah, caabbinta biyaha ee muddada dheer ee hoobiye ayaa si tartiib tartiib ah hoos ugu dhacday. Marka maadada budada cinjirka ah lagu hagaajiyo 10% -16%, shabiir ku salaysan sibidhka wax laga beddelay ma heli karo dabacsanaan wanaagsan oo keliya, laakiin sidoo kale waxay leedahay iska caabbinta biyaha muddada-dheer.
