Guhitamo iburyo bwa RDP polymer ya tile yometse hamwe na putty

Amabati yometse hamwe na putty agomba kuba afite ibicuruzwa mubikorwa byubwubatsi. Byakoreshejwe muguhuza amabati yubutaka ahantu hatandukanye, harimo inkuta hasi. Ikintu cyingenzi cyibicuruzwa ni RDP polymer. RDP isobanura Redispersible Polymer Powder, ikaba kopolymer ya vinyl acetate na Ethylene. Polimeri igira uruhare runini muburyo bwo gufatira hamwe no gushira kandi bigira ingaruka kumitungo itandukanye, harimo gufatana, guhuza, kuramba no gutunganywa. Iyi ngingo izaganira ku bintu ugomba gusuzuma muguhitamo polimeri ya RDP ikwiye n'ingaruka zayo kuri tile yometse kuri pile.

1. Gufatanya

Adhesion nubushobozi bwibicuruzwa gukomera kumiterere itandukanye. Ibikoresho bifatika bya polymers ya RDP biterwa nimiterere yimiti, uburemere bwa molekile hamwe nintera yo guhuza polymer. Imiterere yimiti ya RDP polymer igena ubwoko bwimiterere ihuye nayo. Kurugero, vinyl acetate yibigize polymer ifatanye cyane hejuru yimiterere idafite inkingi nka PVC na PE. Ku rundi ruhande, Ethylene, ifatanye cyane hejuru ya polar nka beto nimbaho.

Kugirango ugere ku gukomera gukomeye, birasabwa gukoresha uburemere buke bwa RDP polymers. Uburemere buremereye bwa polymer butera imbaraga zikomeye za intermolecular, bikavamo gukomera neza. Urwego rwo guhuza rugira ingaruka ku gukemuka kwa polymer RDP bityo imiterere yacyo. Byinshi bihujwe na polymers ntibishobora gukemuka kandi bifite imiterere yo gufatira munsi ugereranije na polimeri nkeya.

2. Guhuriza hamwe

Guhuriza hamwe bivuga ubushobozi bwibicuruzwa kwizirikaho ubwabyo. Imiterere ihuriweho na RDP polymers ifitanye isano nubushyuhe bwikirahure (Tg) bwa polymer. Tg ya polymer ya RDP igena ubushyuhe aho polymer iva muri rubberi ikajya mubirahure. Polimeri ifite Tg hejuru yubushyuhe bwicyumba yerekana ubumwe bwiza, mugihe polymers ifite Tg munsi yubushyuhe bwicyumba yerekana ubumwe bubi.

Kubufatanye bwiza, birasabwa gukoresha polymers ya RDP hamwe na Tg hejuru yubushyuhe bwicyumba. Polimeri yo hejuru ya Tg itera imbaraga zikomeye za intermolecular, bikavamo ubumwe bwiza. Birasabwa kandi gukoresha uburemere buke bwa RDP polymers kugirango wongere ubumwe.

3. Kuramba

Kuramba ni umutungo wingenzi wa tile yometse kandi ushira. Kuramba kwa polymers ya RDP bigira ingaruka kubirwanya amazi, ubushyuhe no kwangirika kwa UV. Vinyl acetate yibigize polymer RDP yunvikana na hydrolysis, bigatuma kugabanuka kuramba mubihe bitose.

Kugirango uzamure igihe kirekire, birasabwa gukoresha polimeri ya RDP irimo etilene nyinshi. Vinyl ifite amazi meza nubushuhe bwamazi bityo ikagira igihe kirekire. Polimeri ya RDP ifite vinyl acetate nkeya nayo irerekana igihe kirekire. Byongeye kandi, RDP polymers hamwe na UV nziza irwanya irasabwa kubisabwa hanze.

4. Gutunganywa

Gukora bivuga ubworoherane bwo gukoresha tile yometse hamwe na formulaire. Gutunganya polymers ya RDP bigira ingaruka kubunini bwazo, ubwinshi bwinshi, no gutatana. Ingano ntoya ya polimeri ya RDP yerekana uburyo bwiza bwo gutunganywa kuko ikwirakwira vuba mumazi, bikavamo kuvanga neza cyangwa kuvanga. Byongeye kandi, polimeri ya RDP ifite ubucucike buke bwerekana uburyo bwiza bwo gukora neza kuko bisaba imbaraga nke zo kuvanga.

Kunoza imikorere, birasabwa gukoresha polimeri ya RDP ifite ingano ntoya nubucucike buke. Byongeye kandi, birasabwa gukoresha polymers ya RDP ifite itandukaniro ryinshi mumazi kugirango igere vuba kandi ivanze neza.

mu gusoza

Guhitamo iburyo bwa RDP polymer ya tile yometse hamwe na putty ni ngombwa kugirango ugere ku bicuruzwa byiza. Gufatanya, guhuriza hamwe, kuramba no gutunganya polymer bigira ingaruka kumikorere yibicuruzwa. Ibintu ugomba gusuzuma muguhitamo polymer ikwiye ya RDP harimo imiterere yimiti, uburemere bwa molekile, urugero rwo guhuza, ubushyuhe bwinzibacyuho, kurwanya amazi, ubushyuhe no kwangirika kwa UV, ingano yibice, ubwinshi bwinshi no gutatana. Kuzirikana witonze kuri ibi bintu birashobora kuganisha ku guhitamo neza kwa RDP polymer hamwe no gufata neza tile hamwe no gushira.
