Ekwakhiweni kwanamuhla, ukuzuza ukukhiqizwa okuhle nokunamathela ezintweni zokwakha kubalulekile ekuqineni kanye nekhwalithi yezakhiwo. Ama-polymer powders (RDP) aqhamuke njengezengezo ezibalulekile ezithuthukisa kakhulu lezi zindawo.
Ukuqonda kabusha i-polymer powders
Ama-polymer powders abuyiselwe ama-polymer anamanzi angenamanzi, amapontshi agelezelele amahhala akhiwa yi-Spray-Spray Emulsions. Lawa mapode asetshenziswa kakhulu ekwakhekeni kodaka kodaka. Lapho uxubana namanzi, i-RDP ibuyela kwisimo sayo sokuqala se-emulsion, ukuthuthukisa izakhiwo zodaka. Izinhlobo ezivame kakhulu ze-RDP zifaka phakathi i-vinyl acetate-ethylene (VAE) Copolymers, i-vinyl ester ye-copolymers ehlukahlukene (Veova) Copolymers, nama-acrylic admers.
Ukuthuthukisa Ukusetshenziswa nge-RDP
Ukusebenza kubhekisele kalula lapho udaka noma ukuhlanganiswa kokhonkolo kungaxutshwa khona, kubekwe, kuhlanganiswe, futhi kuqediwe ngaphandle kokuhlukaniswa. Ukusebenza okuhle kubalulekile ukuze kuqinisekiswe ukuthi ukuxubana kungasetshenziswa kahle nangendlela efanele.
Ukuguquguquka okuthuthukisiwe kanye nokugeleza: I-RDP ithuthukisa izakhiwo zesimbozo sodaka lokuxubana, okwenza ukuba bakhanyele kakhulu futhi kube lula ukubhekana nakho. Ama-polymers anciphisa ukungqubuzana phakathi kwezinhlayiya, okuholela ekuhlanganiseni okubushelelezi. Lokhu kuyazuzisa kakhulu kuzinhlelo zokusebenza ezinjengezinhloso ze-tile kanye namakhompiyutha okuzenzela, lapho kudingeka khona ukusakazeka komfaniswano nokungaguquki.
Ukugcinwa kwamanzi: Enye yezinzuzo ezibalulekile ze-RDP yikhono layo lokuthuthukisa ukugcinwa kwamanzi ku -xube. Ukugcinwa kwamanzi okulungile kuqinisekisa ukuthi inqubo yokumathela kwesiko le-hydration ayimiswanga ngaphambi kwesikhathi, okubaluleke kakhulu ekufezekiseni amandla afiselekayo nokuqina. Ukugcinwa kwamanzi okuthuthukile kunciphisa nengozi yokuqhekeka futhi kuthuthukise ukusebenziseka okuphelele ngokugcina ukuxuba okunomswakama nokusebenza isikhathi eside.
Isikhathi Esivuliwe Esivulekile I-RDP inwebisa isikhathi esivulekile, inikeze abasebenzi ukuguquguquka okwengeziwe nesikhathi sokushintsha izinto ngaphandle kokuyekethisa amandla ebhondi. Le mpahla ibaluleke kakhulu ezimweni sezulu ezishisayo lapho ukomisa okusheshayo kungaba yinkinga.
I-Thixotropy: I-RDP inikela ngezakhiwo ze-Thixotropic zodaka, okusho ukuthi ziba yi-viscous encane ngaphansi kwengcindezi ye-shear (njengokuxubana noma uhlelo lokusebenza) futhi zivuselelwa khona lapho izingcindezi zisuswa. Le mpahla iqinisekisa ukuthi udaka uhlala endaweni ngemuva kwesicelo, ukuvimba ukugcwala noma ukuncipha kuzinhlelo zokusebenza mpo.
Ukuthuthukisa ukunxusa nge-RDP
Ukunamathela kuyikhono lezinto ezibonakalayo ezisongeleni ebusweni lapho kusetshenziswa, okubalulekile ebuqothweni obuhle kakhulu kanye nokuphila isikhathi eside kokwakhiwa.
Ukubopha Okuphezulu: I-RDP ithuthukisa ukunamathela kwezingodo ezingezansi ezahlukahlukene, kufaka phakathi ukhonkolo, ubumbano kanye nezinhlobo ezahlukene zama-tile. Izinhlayiya ze-polymer zingena kuma-pores of the substrate futhi zidale ukuhlangana kwemishini, ngenkathi futhi zakha ifilimu ye-polymer ethuthukisa isibopho esinamathela.
Ukuvumelana nezimo kanye nokuguquguquka: I-RDP idlulisela ukuguquguquka kodaka, okuvumela ukuthi kwamukele ukunyakaza okuncane nokukhubazeka ngaphandle kokuqhekeka. Lokhu kuguquguquka kubalulekile ezindaweni lapho kushintsha izinga lokushisa kubangela ukwanda nokubuyiselwa kwezinto zokwakha. Ukuguquguquka okuthuthukisiwe kunciphisa ukucindezela esibophweni, kugcinwe ukunamathela okuqinile ngokuhamba kwesikhathi.
Ukunamathela ku-substrates enzima: odongeni oguqulwe nge-RDP ukhombisa ukunamathela okuthuthukile kwizigatshana eziyinselele, njengezindawo ezibushelelezi noma amathayili amadala. Ama-polymers athuthukisa ikhono elimanzi lodaka, alivumele ukuthi asakaze futhi anamathele kulawa ma-substrates. Lokhu kuwusizo ikakhulukazi kumaphrojekthi wokuvuselelwa lapho izinto ezintsha kufanele ziboshwe ngempumelelo kwizakhiwo ezikhona.
Ukuqina okuthuthukile kanye nokumelana: amafilimu we-polymer akhiwa yi-RDP amelana namanzi, amakhilomitha axakile, namakhemikhali ahlukahlukene, athuthukisa ukuqina kwesibopho. Lokhu kumelana kubucayi kuzicelo zangaphandle nezindawo ezivezwa ukuguquguquka komswakama nokushintsha okushisa.
Izicelo ze-RDP ekwakhiweni
Ukusebenza okuthuthukisiwe kanye nezindawo ezinama-adhesion ezinikezwe yi-RDP ziholele ekusetshenzisweni kwazo okusakazekile ezisekelweni ezahlukahlukene zokwakha:
Ama-Tile anamathela: I-RDP isithako esiyisihluthulelo kuma-tile anamathela, ukuhlinzeka ngesibalo esidingekayo kanye nokusebenza kwawo womabili amathayili odongeni naphansi. Isikhathi esivulekile sokuvulwa nokuguquguquka kuqinisekisa amabhondi aqinile futhi aqinile, ngisho nasezindaweni ezimanzi njengezindlu zokugezela namakhishi.
Amakhompiyutha ezi-self-welveling: kumakhompiyutha ezizikhandlayo, i-RDP iqinisekisa indawo ebushelelezi, efanayo neyunifomu ngokuthuthukisa izakhiwo zokugeleza kokuhlanganiswa. Ukunamathelisa okuthuthukisiwe kuqinisekisa amabhondi ahlanganisiwe kahle ku-substrate, ukuvimbela ukunxusa.
Ukulungisa udaka: Ukulungiswa kodaka, i-RDP inikezela ngesinamathiseli esihle ngokhonkolo wakudala nolusha, ukuqinisekisa ukulungiswa okuhlala isikhathi eside. Ukusebenza okuthuthukile kuvumela uhlelo lokusebenza olulula, ngisho nasekulungisweni okuyinkimbinkimbi.
Ama-Plasters kanye noDenders: I-RDP ithuthukisa ukusebenziseka kanye nokunqwabelanisa kwabahleli kanye nama-render, ukuqiniseka, bahlanganisa kahle izindonga futhi balondoloze ubuqotho babo ngokuhamba kwesikhathi. Ukugcinwa kwamanzi okuthuthukisiwe kuvimbela ukoma ngaphambi kwesikhathi, kunciphisa ubungozi bokuqhekeka.
Izinhlelo zokufakelwa kwe-Thermal Insulal: Ku-Thermalter yangaphandle yokufakelwa kwe-incosite yezinhlelo (i-RDP), i-RDP ithuthukisa ukunamathela kwamapulangwe okufakwayo ku-substrate kanye nejazi lesisekelo ekufakweni. Lokhu kuqinisekisa ukuqina kanye nokusebenza kahle kohlelo.
Ama-polymer polymer powders adlala indima ebalulekile ekwakhiweni kwesimanje ngokwenza ngcono ukusebenziseka kanye nokunamathelisa kodaka nezinye izinto zokwakha. Amandla abo okuthuthukisa ukungaguquguquki, ukugcinwa kwamanzi, isikhathi esivulekile, futhi i-Thixotropy ibenza babaluleke kakhulu ekufezekiseni ukusebenza kahle. Ngasikhathi sinye, iminikelo yabo yokubopha ubugqila, ukuguquguquka, ukunamathela ezingxenyeni ezinzima, futhi ukuqina kuqinisekisa izibopho eziqinile nezihlala njalo. Njengoba imboni yezokwakha iyaqhubeka nokuvela, ukubaluleka kwe-RDP ekuthuthukiseni ukusebenza okuphezulu, izinto zokwakha eziqinile nezisebenza kahle kuzokhula kuphela.
