Ukusetshenziswa kweI-Teatisperible Tleatex Powder (RDP) Ngokwemisebenzi ye-putty powder ibambe ukunakwa embonini yezokwakha kanye nokwakha yokwakha ngenxa yomthelela wayo omkhulu kwizakhiwo zomkhiqizo wokugcina. Ama-polyx powders abuyiselwe ama-polyx ayisisekelo akwazi ukwakha ama-disprings uma axutshwe namanzi. Lokhu kusabalalisa kudlulisela izici ezihlukahlukene ezizuzisayo ku-putty, kufaka phakathi ukuthambekela okuthuthukile, ukuguquguquka, ukumelana kwamanzi, futhi, ikakhulukazi inqubo enzima.
Ukuqonda i-Putty Powder kanye ne-Teatex Powder evuselelayo
I-PuTTY DOWSHOW ngumkhiqizo osuselwa ku-powder osetshenziselwa ukugcwalisa izikhala, izindawo ezibushelelezi, kanye nokulungiselela ama-substrates okupenda noma okunye okuqediwe. Ukwakheka okuyisisekelo kwe-putty powder kuhlanganisa ama-linders (isib Uma kuxutshwe namanzi, i-putty powder yakha unamathisela onzima ngokuhamba kwesikhathi, edala indawo eqinile, ebushelelezi.
I-TeatisperibleTwetx Powder (RDP) iyimpuphu ye-polymer encibilikayo yamanzi eyenziwe nge-Spray-sorying aqurser stravings of polymer emulsions. Ama-polymers ajwayelekile asetshenziswa ku-RDP afaka i-styrene-buthadiene (SBR), i-acrylics, ne-vinyl acetate-ethylene (VAE). Ukungezwa kwe-RDP ku-Putty Powder kuthuthukisa izici ezingokomzimba nezemishini ze-purtty elapha, ngokuyinhloko ngokuthuthukisa amandla ebhondi, ukuguquguquka, kanye nokumelana nokuqhekeka.
Ukuqina kwe-putty powder
I-harding ye-putty powder yenzeka njengezakhi ze-barnents (njenge-clemende noma i-gypsum) ephendula ngamakhemikhali ngamanzi. Inqubo ngokuvamile i-hydration ebizwa nge-hydration (yama-centlies asuselwa ku-crystallization (ama-gypsum-based putties), futhi kuphumela ekwakhekeni kwezigaba eziqinile eziqinisa isikhathi ngokuhamba kwesikhathi. Kodwa-ke, le nqubo ingathonywa ngezinto ezahlukahlukene, njengokuba khona kwezithasiselo, umswakama, izinga lokushisa kanye nokwakhiwa kwe-putty uqobo.
Iqhaza le-RDP kule nqubo elukhuni ukuthuthukisa ubuhlobo phakathi kwezinhlayiya, ngcono ukuguquguquka, kanye nokulawula ukuhwamuka kwamanzi. I-RDP isebenza njenge-binder leyo, yake yabuyiselwa emanzini, yakha inethiwekhi ye-polymeric ngaphakathi kwe-putty. Le nethiwekhi isisiza ukubamba ama-molekyuli amanzi isikhathi eside, yehlisa izinga lokuhwamuka futhi ngaleyo ndlela linwebe isikhathi sokusebenza se-putty. Ngokwengeziwe, inethiwekhi ye-polymer isiza ukwakha i-STREPER, ROASIve Hard Earted Mass ngokwenza ngcono ukuxhumana kwezinhlayiya.
Umthelela we-latex evuselelayo ye-latex yenqubo eqinile
Ukusebenza okwenziwe ngcono nesikhathi esivulekile:
Ukufakwa kwe-RDP e-Putty Distream kuthuthukisa ukusebenziseka ngokunciphisa ukwehlisa inqubo yokomisa, kunikeze isikhathi esithe xaxa sokufaka isicelo. Lokhu kuyazuzisa kakhulu kumaphrojekthi amakhulu lapho i-Putty idinga ukusakazeka ezindaweni ezibanzi ngaphambi kokuba zibekwe.
Ukuguquguquka okwengeziwe:
Enye yemiphumela ebalulekile yokungeza i-RDP ukuthuthuka ngokuguquguqukayo. Ngenkathi i-putty yendabuko ithambekele ekuziphatheni, i-RDP inikela ngezinto zokwelapha eziguquguqukayo, zinciphisa amathuba okuqhekeka ngaphansi kokushintshashintsha kwengcindezi noma lokushintshashintsha kwezinga lokushisa.
Amandla nokuqina:
Ama-CDP-Modified Petties abonisa amandla aphezulu acindezelayo kanye nokumelana nokugqoka nokuzitaza uma kuqhathaniswa nokwakhiwa okungaguquki. Lokhu kungenxa yokwakheka kwe-matrix ye-polymer okuqinisa ubuqiniso besakhiwo se-putty elukhuni.
Kuncishiswe i-shrinkage:
Inethiwekhi ye-polymeric eyenziwe nge-latex evuselelayo ye-latex powder nayo iyasiza ekunciphiseni i-shrinkage yenqubo yokwelapha. Lokhu kubaluleke kakhulu ekuvikeleni ukwakheka kwemifantu, okungahlehlisa ukusebenza nokuhlehlisa isipuni.
Ukumelana Amanzi:
I-putty powder ehlanganiswe ne-latex evuselelayo ye-latex ivama ukuba ingamelana namanzi. Izinhlayiya ze-latex zakha ungqimba lwe-hydrophobic ngaphakathi kwe-putty, okwenza umkhiqizo welapha ungathathi kalula ukumuncwa kwamanzi futhi, ngakho-ke, kufaneleka kangcono izinhlelo zokusebenza zangaphandle.
Ukufaka i-latex ye-latex evuselelayo ku-turty ukwakheka kuthuthukisa kahle izakhiwo zayo, ikakhulukazi ngesikhathi senqubo enzima. Izinzuzo ezisemqoka ze-RDP zifaka ukukhiqizwa okuthuthukile, ukuguquguquka okuthuthukile, amandla akhuphukayo nokuqina, ukuncipha kwe-shrinkage, kanye nokumelana kwamanzi okungcono. Lokhu kuthuthuka kwenza ama-rdp-modified ama-tupties afaneleke kakhudlwana kuzo zombili izinhlelo zokusebenza zangaphakathi nezingaphandle, enikeza isikhathi eside nokusebenza okuhlukahlukene ngaphansi kwezimo zemvelo ezahlukahlukene.
Ochwepheshe bezokwakha nabakhiqizi, ukusetshenziswa kweI-redisperible latex powder Inikeza indlela elula nokho ephumelelayo yokuthuthukisa izakhiwo zama-powers endabuko amaPutty Powders, okuholele ekutheni kube lula ukufaka isicelo, okuhlala isikhathi eside, futhi kuthambekele ekuqhekekeni kwesikhathi. Ngokwandisa ukwakhiwa nge-RDP, amaPutty Powders aguquguqukayo ngokwengeziwe, ngokuthuthukiswa kokusebenza okuphelele maqondana nokunamathelisa, ubunzima, kanye nokumelana nezinto.
