Umgubo wepolymer ophinda uqhekeke (RDP)Idlala indima ebalulekileyo ekwenziweni kweempuphu ze-putty, ezisetyenziselwa ukusetyenziswa ezahlukeneyo, kubandakanya ukulungiswa kodonga nomgangatho, ukulungiswa, kunye nokuthambisa umphezulu. Ezi mpuphu zihlala zenziwe ngee-polymers zokwenziwa ezomileyo zaza zagaywa zaba ngamasuntswana amancinci, anokuxutywa namanzi ukuze enze intlama okanye i-slurry. Xa zongezwa kwimpuphu ye-putty, i-RDP iphucula kakhulu ukusebenza kunye nokusebenza kwe-putty.
Yintoni iRedispersible Polymer Powder (RDP)?
Umgubo wepolymer ophinda udityaniswe kwakhona yipowder eyomileyo, ehamba ngokukhululekileyo eyenziwe ngeepolymers ze-emulsion, edla ngokusekwe kwi-styrene-acrylic, acrylic, okanye i-vinyl acetate-ethylene copolymers. Ezi polymers zenziwe ngononophelo ukuze zikwazi ukuphinda zidityaniswe emanzini xa zidityaniswe kwifomyula. Xa kongezwa amanzi, umgubo uphinda umanzise kwaye wenze ifilimu yepolymer efanayo ngaphakathi komxube.
Ukubaluleka kwe-RDP kukwikhono layo lokuphucula iimpawu ze-putty okanye i-adhesive. Inethiwekhi ye-polymer ephumayo inika iipropati ezibalulekileyo ezinje ngokunamathela okuphuculweyo, ukuguquguquka, kunye nokuqina.
Iingenelo eziphambili ze-RDP kwiPutty Powders
Ukunamathela okuphuculweyo
Omnye wemisebenzi ebaluleke kakhulu ye-RDP kwi-putty formulations kukuphucula ukunamathela. I-RDP inegalelo ekudibaniseni okuqinileyo phakathi kwe-putty kunye nomphezulu esetyenziswa kuwo. Umzekelo, kwi-wall putty, inceda ekudibaniseni i-putty kwi-substrates ezahlukeneyo ezifana nekhonkrithi, i-drywall, okanye izitena. Inethiwekhi ye-polymer eyenziweyo kumxube ivumela i-putty ukuba inamathele ngokufanelekileyo kwezi ndawo, nokuba azinazo imingxuma okanye azilingani.
Ukuguquguquka Okuphuculweyo
Iipowuda zeputty ezixutywe neRDP zinika ukuguquguquka okungcono kunezo zingenayo. Olu phawu lubaluleke kakhulu xa lusetyenziswa kwiindawo ezitshintshatshintsha ubushushu okanye ezishukumayo, ezifana neendonga kwizakhiwo. I-RDP ivumela iputty ukuba yande kwaye inciphe ngaphandle kokuqhekeka, nto leyo ekhokelela ekugqityweni komphezulu okuhlala ixesha elide nokuqina ngakumbi.
Ukuphuculwa Kokusebenza
Umgubo wepolymer ophinda usetyenziswe uyawomeleza amandla okusebenza kwe-putty. Inika ukuqina okuthambileyo, okukhrimu okulula ukukusasaza nokugudileyo kumphezulu. Olu phawu alubalulekanga nje kuphela ekusetyenzisweni lula kodwa nasekufezekiseni ukugqitywa okufanayo, okuthandekayo ngobuhle. Ukwanda kokuhamba kwamanzi kunye nokusasazeka lula kunceda ekufezekiseni ubukhulu obuhambelanayo kumphezulu ophathwayo.
Ukumelana namanzi
Enye yeenzuzo eziphambili ze-putty exutywe ne-RDP kukuphucula ukumelana kwayo namanzi. I-polymer yenza umqobo onciphisa ukungena kwamanzi kwi-putty. Oku kwenza imveliso yokugqibela imelane ngakumbi nezinto ezingqongileyo ezifana nokufuma kunye nokufuma. Kwii-putty ezifakwe kwiindonga zangaphandle okanye kwiindawo ezinomswakama ophezulu (njengezindlu zangasese), olu phawu lubalulekile ukuqinisekisa ukuhlala ixesha elide nokusebenza kakuhle.
Ukumelana nokuqhekeka kunye nokuqina
I-RDP iphucula ukumelana nokuqhekeka kwee-putty. I-polymer inika ukuguquguquka, ithintela ukwakheka kwee-cracks njengoko i-putty yoma kwaye iphola. Oku kubaluleke kakhulu kwiindawo ezinkulu apho ukoma okungalinganiyo kunokukhokelela ekuqhekekeni. Ngaphezu koko, i-putty ephuculweyo ye-polymer igcina ukuqina kwayo kwesakhiwo ngokuhamba kwexesha, iqinisekisa iziphumo ezihlala ixesha elide.
Ukuphucula ukuSanda kunye noMgangatho wokugqiba
Emva kokulungiswa kwe-putty, i-RDP inceda ekufezekiseni ukugqitywa okugudileyo okunokucocwa ngokulula ngaphandle kokuvelisa uthuli oluninzi. Oku kubalulekile ekufezekiseni umphezulu osemgangathweni ophezulu ogudileyo, othe tyaba, kwaye ofanelekileyo ukupeyinta okanye ukuhombisa ngakumbi. Ubume obufanayo kunye neempawu zokucocwa ezingcono zinegalelo ekugqityweni komgangatho ophezulu kwiiprojekthi zokwakha.
Ukumelana Okuphuculweyo Nezinto Ezingqongileyo
Ukusetyenziswa kweepowder zepolymer eziphinda zichithwe kwandisa ukumelana kwe-putty kwizinto ezahlukeneyo ezingqongileyo, kubandakanya ukubola kwe-UV, ukukrala, kunye nokuvezwa ziikhemikhali. Kwizicelo zangaphandle, oku kuqinisekisa ukuba i-putty igcina iimpawu zayo nokuba kwiimeko zemozulu ezinzima.

Indlela i-RDP ephucula ngayo ukwenziwa kwe-putty
Ukusetyenziswa kwe-RDP kwimibhobho ye-putty kudlula nje ukunamathelana okulula. Xa ixutywe namanzi, umgubo we-polymer uphinde usasazeke ube ziingceba ze-polymer ezizimeleyo ezenza ifilimu eguquguqukayo nedibeneyo ngaphakathi kwe-putty. Le nethwekhi ye-polymer isebenza njengesihlanganisi, ibamba iingceba ze-putty kunye kwaye iqinisekisa ukuhambelana kokwenziwa.
Ngaphezu koko, iipropati eziphuculweyo ngokubhekiselele ekuguquguqukeni, ukumelana namanzi, kunye nokuqina kwenza i-RDP ibe sisongezelelo esixabisekileyo, ngakumbi kwizicelo ezivezwe kwizinto okanye ezifuna ukusebenza ixesha elide.
Umzekelo, kwiiputty zodonga zangaphandle okanye kwiikhompawundi zokulungisa umgangatho, apho ukuvezwa kokusingqongileyo kuyingxaki, amandla eputty okumelana nokufuma, imisebe ye-UV, kunye nokwanda kobushushu kubalulekile ukuze unyango lomphezulu luhlale ixesha elide. I-RDP inegalelo elikhulu kwezi mpawu, okwenza iputty ifaneleke ngakumbi ukusetyenziswa kwiindawo zangaphakathi nangaphandle.
Umgubo wepolymer ophinda uchithekesisithako esibalulekileyo ekubunjweni kwe-putty powders. Igalelo layo ekunamatheleni, ukuguquguquka, ukumelana namanzi, ukumelana nokuqhekeka, kunye nokuqina ngokubanzi kwenza ukuba ibe yinto efunekayo ekufezekiseni iziphumo ezisemgangathweni ophezulu. Nokuba kukulungiswa komphezulu, ukulungiswa, okanye ukusetyenziswa kokuhombisa, i-putty ephuculweyo nge-RDP iqinisekisa ukugqitywa okugudileyo, kobuchwephesha kunye nobude obuphuculweyo.
Ngokuphucula zombini iimpawu zokusebenza kunye nobuhle be-putty, i-RDP iguqule indlela iingcali zokwakha ezijongana ngayo nokulungiswa komphezulu. Ngeentlobo ngeentlobo zeenzuzo ezichazwe apha, kuyacaca ukuba kutheni i-RDP ibe yinxalenye ebalulekileyo kwi-putty formulations.
