Ukusetyenziswa kweumgubo welatex ophinda unyibilike (RDP) Kwi-putty powder formulations ifumene ingqalelo kwishishini lokwakha nezinto zokwakha ngenxa yempembelelo yayo ebalulekileyo kwiimpawu zemveliso yokugqibela. Iipowder zelatex eziphinda zichithwe kwakhona ziyipowder zepolymer ezikwaziyo ukwenza i-dispersions xa zidityaniswe namanzi. Ezi dispersions zinika iimpawu ezahlukeneyo eziluncedo kwi-putty, kubandakanya ukunamathela okuphuculweyo, ukuguquguquka, ukumelana namanzi, kwaye, okubaluleke kakhulu, inkqubo yokuqina.
Ukuqonda iPutty Powder kunye neRedispersible Latex Powder
I-putty powder yimveliso esekwe kwi-powder ecolekileyo esetyenziselwa ukugcwalisa izikhewu, ukuthambisa iindawo, kunye nokulungiselela izinto zokufaka ipeyinti okanye ezinye izinto ezigqityiweyo. Ulwakhiwo olusisiseko lwe-putty powder ludla ngokuquka izinto zokubopha (umz., isamente, i-gypsum), izizalisi (umz., i-talc, i-calcium carbonate), kunye nezongezo (umz., izithinteli, izikhawulezisi) ezilawula iimpawu zayo zokusebenza. Xa ixutywe namanzi, i-putty powder yenza intlama eqina ngokuhamba kwexesha, idale umphezulu oqinileyo nothambileyo.
I-Redispersible latex powder (RDP) yi-polymer powder enyibilikayo emanzini eyenziwe ngokufafaza ngamanzi acrylic emulsions. Ii-polymers eziqhelekileyo ezisetyenziswa kwi-RDP ziquka i-styrene-butadiene (SBR), i-acrylics, kunye ne-vinyl acetate-ethylene (VAE). Ukongezwa kwe-RDP kwi-putty powder kuphucula iimpawu zomzimba neze-mechanical ze-cured putty, ngokuyintloko ngokuphucula amandla okubopha, ukuguquguquka, kunye nokumelana nokuqhekeka.
Ukuqina kwePutty Powder
Ukuqina komgubo we-putty kwenzeka njengoko izinto ezidibanisayo (ezifana nesamente okanye i-gypsum) zidibana namanzi. Le nkqubo ibizwa ngokuba yi-hydration (kwi-putty esekelwe kwisamente) okanye i-crystallization (kwi-putty esekelwe kwi-gypsum), kwaye iphumela ekwakhiweni kwezigaba eziqinileyo eziqina ngokuhamba kwexesha. Nangona kunjalo, le nkqubo inokuchatshazelwa zizinto ezahlukeneyo, ezinje ngokubakho kwezongezo, ukufuma, ubushushu, kunye nokwakheka kwe-putty ngokwayo.
Indima ye-RDP kule nkqubo yokuqina kukuphucula ukubopha phakathi kweesuntswana, ukuphucula ukuguquguquka, kunye nokulawula ukufuma kwamanzi. I-RDP isebenza njengesihlanganisi, xa sele iphinda yachithwa emanzini, yenza inethiwekhi yepolymeric ngaphakathi kwe-putty. Le nethiwekhi inceda ekubambeni iimolekyuli zamanzi ixesha elide, inciphisa isantya sokufuma kwaye ngaloo ndlela yandisa ixesha lokusebenza kwe-putty. Ukongeza, inethiwekhi yepolymer inceda ekwakheni ubunzima obuqinileyo nobumanyeneyo ngokuphucula ukusebenzisana kweesuntswana.
Impembelelo ye-Redispersible Latex Powder kwiNkqubo yoKuqiniswa
Ukuphuculwa Kokusebenza Nexesha Elivulekileyo:
Ukufakwa kwe-RDP kwiifomyula ze-putty kuphucula ukusebenza ngokucothisa inkqubo yokomisa, okunika ixesha elingakumbi lokusetyenziswa. Oku kuluncedo ngakumbi kwiiprojekthi ezinkulu apho i-putty kufuneka isasazwe kwiindawo ezinkulu ngaphambi kokuba iqine.
Ukuguquguquka Okungakumbi:
Enye yeziphumo ezibalulekileyo zokongeza i-RDP kukuphucula ukuguquguquka. Nangona i-putty yendabuko idla ngokuba buthathaka xa iqina, i-RDP inegalelo kwizixhobo eziguquguqukayo ngakumbi, nto leyo enciphisa amathuba okuqhekeka phantsi koxinzelelo okanye ukuguquguquka kobushushu.
Amandla Nokuqina:
Ii-putty eziguqulwe yi-RDP zinamandla aphezulu okucinezelwa kunye nokumelana nokuguguleka xa kuthelekiswa neefomyula ezingaguqulwanga. Oku kungenxa yokwenziwa kwe-polymer matrix eqinisa ukuqina kwesakhiwo se-putty eqinileyo.
Ukuncipha kokuncipha:
Inethiwekhi yepolymeric eyenziwe yi-latex powder ephinda inyibilike ikwanceda ekunciphiseni ukushwabana ngexesha lenkqubo yokucola. Oku kubaluleke kakhulu ekuthinteleni ukwakheka kwemifantu, enokuthi iphazamise ukusebenza kunye nobuhle be-putty.
Ukumelana namanzi:
Umgubo we-putty oxutywe nomgubo we-latex ophinda uchitheke udla ngokuba namandla okumelana namanzi. Amasuntswana e-latex enza umaleko ongangeni manzi ngaphakathi kwe-putty, nto leyo eyenza imveliso ecociweyo ingabi sengozini yokufunxwa ngamanzi, ngoko ke, ifaneleke ngakumbi ukusetyenziswa ngaphandle.
Ukufaka i-latex powder ephinda inyibilike kwi-putty formulations kuphucula kakhulu iipropati zayo, ingakumbi ngexesha lenkqubo yokuqina. Iingenelo eziphambili ze-RDP ziquka ukuphucula ukusebenza, ukuguquguquka okuphuculweyo, ukomelela okwandisiweyo kunye nokuqina, ukunciphisa ukuncitshiswa, kunye nokumelana okungcono kwamanzi. Olu phuculo lwenza i-RDP-modified putty ifaneleke ngakumbi kwiindlela zangaphakathi nezangaphandle, inika ixesha elide kunye nokusebenza phantsi kweemeko ezahlukeneyo zendalo.
Kwiingcali zokwakha kunye nabavelisi, ukusetyenziswaumgubo welatex ophinda unyibilike Inika indlela elula kodwa esebenzayo yokuphucula iipropati zeempuphu ze-putty zemveli, nto leyo ephumela kwimveliso elula ukuyisebenzisa, ehlala ixesha elide, kwaye engenakuqhekeka okanye ukushwabana ngokuhamba kwexesha. Ngokusebenzisa kakuhle ifomyula nge-RDP, iimpuphu ze-putty ziyaguquguquka ngakumbi, kunye nokusebenza okuphuculweyo ngokubanzi ngokubhekiselele ekunamatheleni, ubulukhuni, kunye nokumelana nezinto.
