I-redispersible polymer powder (RDP) i-emulsion ye-polymer encibilika emanzini. Le nto isetshenziswa kakhulu embonini yezokwakha, ngokuyinhloko njengesibopho sikasimende nezinye izinto zokwakha. Amandla ebhondi ye-RDP iyipharamitha ebalulekile ekusetshenzisweni kwayo njengoba ithinta ngokuqondile izakhiwo zomkhiqizo wokugcina. Ngakho-ke, kubalulekile ukuba nendlela yokuhlola enembile nethembekile ukukala amandla ebhondi e-RDP.
Izindlela Zokuhlola
Okubalulekile
Izinto ezidingekayo ukwenza lokhu kuhlolwa yilezi ezilandelayo:
1. Isibonelo se-RDP
2. I-aluminium substrate enesanti
3. Iphepha elifakwe inhlaka (300um ukujiya)
4. I-adhesive esekelwe emanzini
5. Umshini wokuhlola i-Tensile
6. I-Vernier caliper
uhlelo lokuhlola
1. Ukulungiswa kwamasampula e-RDP: Amasampula e-RDP kufanele alungiswe nenani elifanele lamanzi njengoba kucaciswe umenzi. Amasampula kufanele alungiswe ngokwezidingo zohlelo lokusebenza.
2. Ukulungiswa kwe-substrate: I-substrate ye-aluminium ngemva kokuqhunyiswa kwesihlabathi kufanele ihlanzwe futhi yomiswe ngaphambi kokusetshenziswa. Ngemuva kokuhlanza, ukuqina kwendawo kufanele kulinganiswe nge-vernier caliper.
3. Ukusetshenziswa kwe-RDP: I-RDP kufanele isetshenziswe kwi-substrate ngokulandela imiyalelo yomkhiqizi. Ubukhulu befilimu kufanele bulinganiswe kusetshenziswa i-vernier caliper.
4. Ukwelapha: I-RDP kufanele yelaphe phakathi nesikhathi esishiwo umenzi. Isikhathi sokwelapha singahluka kuye ngohlobo lwe-RDP esetshenzisiwe.
5. Ukusetshenziswa kwephepha elifakwe inhlaka: Iphepha elifakwe inhlaka kufanele lisikwe libe yimichilo yosayizi nokuma okufanelekile. Iphepha kufanele lihlanganiswe ngokulinganayo nge-adhesive yamanzi.
6. Ukunamathisela amapheshana ephepha: Imichilo yephepha enamathelisiwe kufanele ibekwe phezu kwe-RDP coated substrate. Ukucindezela okukhanyayo kufanele kusetshenziswe ukuze kuqinisekiswe ukubopha okufanele.
7. Ukwelapha: Okunamathelayo kufanele kwelaphe phakathi nesikhathi esishiwo umenzi.
8. Ukuhlolwa kwe-tensile: Layisha isampula emshinini wokuhlola oqinile. Amandla okuqina kufanele kurekhodwe.
9. Ukubala: Amandla ebhondi ye-RDP kufanele abalwe njengamandla adingekayo ukuze kuhlukaniswe i-RDP substrate ehlanganiswe nephepha elihlukaniswe ngendawo engaphezulu ye-RDP ehlanganiswe nengaphansi.
Ekuphetheni
Indlela yokuhlola iyindlela elula nengabizi kakhulu yokulinganisa amandla ebhondi ye-RDP. Le ndlela ingasetshenziswa ocwaningweni nasezinhlelweni zezimboni ukuqinisekisa ukusebenza kahle kwe-RDP kusimende nezinye izinto zokwakha. Ukusebenzisa le ndlela kungasiza ekuthuthukiseni ukulawulwa kwekhwalithi nokuthuthukiswa komkhiqizo embonini yezokwakha.
