Njengengxenye ebalulekile yezinto zokwakha zesimanje, izimpushana ze-polymer ezihlakazeka kabusha (RDP) zidlala indima ebalulekile ezinhlelweni eziningi ezifana nodaka, ama-putty, ama-grouts, izinto zokunamathisela zamathayili nezinhlelo zokushisa ezishisayo.Ikhono lokwenza ifilimu le-RDP liyisici esibalulekile esithinta ikhwalithi yomkhiqizo wokugcina.Ukuhlakazeka kabusha kwezimpushana ngemva kokugcinwa, ukuthutha nokuxuba kubalulekile.Kungakho izindlela zokuhlola ezinemininingwane neziqinile zibalulekile ukuze kuqinisekiswe ukufaneleka nokusebenza ngempumelelo kwemikhiqizo ye-RDP.
Esinye sezivivinyo ezibaluleke kakhulu zekhono le-RDP lokwenza ifilimu yindlela yokuhlola yokwenza ifilimu ye-powder redispersible emulsion powder.Le ndlela yokuhlola isetshenziswa kakhulu ekuhlolweni kwekhwalithi yomkhiqizo kanye nenqubo ye-R&D yemikhiqizo ye-RDP.Indlela yokuhlola ukwenza ifilimu yempushana ehlakazeka kabusha ye-polymer powder iyindlela elula futhi elula yokuhlola, engahlola ngempumelelo ikhono lokwenza ifilimu lemikhiqizo ye-RDP.
Okokuqala, i-redispersibility ye-powder kufanele ihlolwe ngaphambi kokuhlolwa kokubunjwa kwefilimu.Ukuxuba i-powder ngamanzi nokugqugquzela ukusabalalisa kabusha izinhlayiya ze-polymer kuqinisekisa ukuthi i-powder isebenza ngokwanele ekuhlolweni.
Okulandelayo, Indlela Yokuhlola Yokwakheka Kwefilimu Ye-Powder Redispersible Polymer ingaqalwa.Izinga lokushisa elimisiwe kanye nomswakama olinganiselwe kuyadingeka ukuze kugcinwe indawo ezinzile ukuze ifilimu yelapheke kahle.Izinto ezisetshenziswayo zifuthwa ku-substrate ngogqinsi oluchazwe ngaphambilini.I-substrate material izoncika ezidingweni zohlelo lokusebenza.Isibonelo, isicelo sodaka singadinga i-substrate ekhonkolo.Ngemuva kokufafaza, izinto zivunyelwe ukuba zome isikhathi esithile, emva kwalokho ikhono lokwenza ifilimu lingahlolwa.
Indlela Yokuhlola Yokwakheka Kwefilimu Ye-Powder Redispersible Emulsion Powder ihlola izici ezimbalwa.Lokhu kufaka phakathi ukuphela kwendawo, ukunamathela kanye nokuguquguquka kwefilimu.Ukuphela kwendawo kungahlolwa ngokubona ngokuhlola noma kusetshenziswa isibonakhulu.Ukunamathela kwefilimu ku-substrate kunqunywe kusetshenziswa ukuhlolwa kwe-tape.Ukunamathela okwanele kuboniswa lapho i-strip of tape isetshenziswa ezintweni futhi ifilimu isala inamathele ku-substrate ngemva kokususwa kwe-tape.Ukuguquguquka kwefilimu nakho kungahlolwa kusetshenziswa ukuhlolwa kwetheyiphu.Yelula ifilimu ngaphambi kokukhipha i-tape, uma ihlala inamathele ku-substrate, ibonisa izinga elifanele lokuguquguquka.
Kubalulekile ukulandela izinqubo zokuhlola ezifanele ukuqinisekisa imiphumela engaguquki.Izici eziningana zokuhlolwa kokwakheka kwefilimu kufanele zifane ukuze kuqedwe ukuhluka phakathi kwamaqoqo ahlukene okuhlola.Lokhu kufaka phakathi izinqubo zokulungiselela, izinga lokushisa, umswakama, ukushuba kwesicelo kanye nesikhathi sokuphulukisa.Ukuhlolwa kwe-tape nakho kudinga ukwenziwa ngengcindezi efanayo ukuze uthole imiphumela eqhathanisekayo.Ngaphezu kwalokho, izinto zokuhlola kufanele zilinganiswe ngaphambi kokuhlolwa.Lokhu kuqinisekisa izilinganiso ezinembile nezinembayo.
Okokugcina, ukuchazwa okunembile kwemiphumela ye-Powder Redispersible Emulsion Powder Film Formation Method kubaluleke kakhulu.Imiphumela etholwe ngendlela yokuhlola ukwakheka kwefilimu kufanele iqhathaniswe namazinga amisiwe okusetshenziswa kwezinto ezithile.Uma ifilimu ihlangabezana nezidingo kanye nokucaciswa, ikhwalithi yayo ithathwa njengeyamukelekayo.Uma kungenjalo, umkhiqizo ungase udinge ukucwengwa okwengeziwe noma ukuguqulwa ukuze uthuthukise izici zawo zokwenza ifilimu.Imiphumela yokuhlolwa ingase futhi isize ekuxazululeni izinkinga nasekuhlonzeni noma yiziphi izinkinga zokukhiqiza noma izinkinga zomkhiqizo.
Kafushane, indlela yokuhlola ukwakheka kwefilimu ye-polymer eyimpushana ehlakazeka idlala indima ebalulekile ekunqumeni ukusebenza kahle komkhiqizo wempuphu ye-polymer ehlakazekayo.Njengenye yezingxenye ezibalulekile zezinto zokwakha zesimanje, ikhono lokwenza ifilimu le-RDP libalulekile ekusebenzeni kwayo.Ukuqinisekisa ukuthi ikhono lokwenza ifilimu ye-RDP liyahlangabezana nezinto ezifiselekayo kubalulekile ekuthuthukiseni ukusebenza nempilo yonke yomkhiqizo wokugcina.Ukubambelela ngendlela efanele ezinkambisweni zokuhlola kubalulekile ukuze uthole imiphumela engaguquki.Ukuchazwa kahle kwemiphumela yokuhlolwa kunganikeza nemininingwane ebalulekile ekwakhiweni nasekukhiqizweni kwemikhiqizo ye-RDP yekhwalithi ephezulu.
