Umgubo welatex ophinda unyibilikeyi-powder dispersion efunyenwe ngokutshiza i-spray drying ye-modified polymer emulsion. Iyakwazi ukusasazeka kwaye ingaphinda ixutywe ibe yi-polymer emulsion ezinzileyo emva kokongeza amanzi. Iipropati zayo zeekhemikhali zifana ngqo ne-emulsion yokuqala. Ke ngoko, Ukuze kwenzeke ukuvelisa i-mortar exutywe nomileyo esemgangathweni ophezulu kwaye ngaloo ndlela kuphuculwe ukusebenza kwe-mortar, namhlanje siza kuthetha ngendima kunye nokusetyenziswa kwe-polymer powder ephinda ixutywe.
Zithini imisebenzi yomgubo welatex ophinda uchitheke?
Umgubo wepolymer ophinde waxutywa kwakhona sisongezelelo esisebenzayo esiyimfuneko kwi-mixed mortar, esinokuphucula ukusebenza kwe-mortar kunye ne-mortar ukuphucula amandla, ukuphucula amandla okubopha kwe-mortar kunye ne-substrates ezahlukeneyo, ukuphucula ipropathi ye-mortar, ukuguquguquka kwamandla okucinezelwa kunye nokuguquguquka, amandla okugoba, ukumelana nokukrweleka, ukuqina, ukunamathela kunye namandla okugcina amanzi, kunye nokusebenza kakuhle komatshini. Ukongeza, ii-polymer powders ezine-hydrophobicity zinokuba nee-mortars ezingangeni manzi kakuhle.
Ukukwazi ukuphinda kunyibilike i-mortar kwinkqubo yokwakhiwa kwe-masonry kunye ne-plaster kukhokelela ekubeni umgubo we-latex ungangeni kakuhle, ukugcinwa kwamanzi, ukumelana neqabaka, kunye namandla aphezulu okubopha, nto leyo enokusombulula ngempumelelo ingxaki yokwakhiwa kwe-mortar yemveli yaseTshayina esebenzisa amagumbi okwakhiwa kwe-masonry. Iingxaki ezikhoyo zolawulo lomgangatho ezifana nokuqhekeka kunye nokungena.
I-mortar ezenzela umlinganiselo, i-latex powder echithwe ngokutsha ukuze isetyenziselwe izinto zomgangatho, inamandla aphezulu, ihambelana/ihambelana kakuhle, kwaye ifuna ukuguquguquka. Iphucula ukunamathela kwezinto, ukumelana nokukrweleka kunye nokugcinwa kwamanzi. Ingazisa i-rheology egqwesileyo, ukusebenza kakuhle kunye neempawu ezilungileyo zokutyibilika kwi-mortar ezenzela umlinganiselo kunye ne-mortar ezenzela umgangatho.
Umgubo welatex ophinda unyibilike onamathela kakuhle, ogcina amanzi kakuhle, ovula ixesha elide, oguquguqukayo, omelana nokuwa, kunye nokumelana okuhle nokuqandisa. Inokuba ngumaleko omncinci wethayile, ithayile kunye neenkozo zerayisi ukuze incamathele kakhulu, imelane kakhulu kwaye isebenze kakuhle ekwakheni.
Umgubo we-latex ophinda udibane nodaka lwekhonkrithi olungangeni manzi uphucula amandla ezinto zokubopha kuzo zonke izinto ezahlukeneyo, unciphisa i-dynamic modulus yokuguquguquka kwamashishini, unyusa ukugcinwa kwamanzi, kwaye unciphisa ukungena kwamanzi. Iimveliso ezibonelela ngee-seal ezineemfuno zokusebenza ezingangeni manzi kunye nokungangeni manzi zokwakha inkqubo imiphumo yesiphumo esihlala ixesha elide.
I-mortar yokukhusela ubushushu bodonga lwangaphandle ingasasaza kwakhona umgubo we-latex kwinkqubo yokukhusela ubushushu bodonga lwangaphandle, yonyuse umanyano lwe-mortar kunye namandla okubopha kwibhodi yokukhusela ubushushu, kwaye inciphise ukusetyenziswa kwamandla ngelixa ifuna i-thermal insulation kuwe. Imveliso ye-mortar yokukhusela ubushushu bodonga lwangaphandle ifezekisa umsebenzi ofunekayo eludongeni lwangaphandle, amandla okuguquguquka kunye nokuguquguquka, ingenza iimveliso zakho ze-mortar zibe neempawu ezilungileyo zokubopha kunye noluhlu lwezinto zokukhusela kunye neengqimba zesiseko, kwangaxeshanye, ikwanceda ukukhankanya ukumelana okuphezulu kunye nokumelana nokuqhekeka komphezulu.
Umgubo welatex ophinda uchitheke ukuze kulungiswe udaka olunobuthambileyo obuhambelanayo, ukushwabana, ukunamathela okuphezulu, iimfuno ezifanelekileyo zokuqina nokuthamba. Iyahlangabezana neemfuno ezingentla zokulungisa udaka ukuze kulungiswe ikhonkrithi yesakhiwo nengeyiyo yesakhiwo.
Umgubo welatex ophinda unyibilike kwi-mortar kwi-interface usetyenziswa kakhulu ekucwangcisweni kwedatha nakwiindawo ezifana nekhonkrithi, ikhonkrithi enomoya, izitena zesanti yelayimu kunye nezitena zomlotha ophaphazelayo. Akulula ukuyibopha, umaleko wokuplasta ugobile, uqhekekile, kwaye uxotyulwe. Amandla okuncamathelisa ayandiswa, akulula ukuwa kwaye ukumelana namanzi, kwaye ukumelana nokuqandisa kugqwala kugqwesileyo, oku kunefuthe elikhulu kwindlela yokusebenza elula kunye nolawulo lokwakha olulula.
Ukusetyenziswa komgubo wepolymer ophinda uchitheke
Isincamathelisi sethayile, udonga lwangaphandle kunye nodonga lwangaphandle lwenkqubo yokugquma ubushushu, udonga lwangaphandle lwenkqubo yokugquma ubushushu, i-grout yethayile, udonga oluzihambelayo, i-putty eguquguqukayo kwiindonga zangaphakathi nezangaphandle, udonga oluguquguqukayo oluchasene nokuqhekeka, umgubo werabha we-polystyrene particle thermal insulation mortar owomileyo.
Amanyathelo okusebenzisa umgubo welatex ophinda unyibilike:
Umgubo welatex ophinda uchitheke awufanelekanga ukuba usetyenziswe kube kanye, kwaye kuyimfuneko ukwahlulahlula ubungakanani ukuze kufunyanwe ubungakanani obufanelekileyo.
Xa kufuneka kongezwe imicu yepolypropylene, kufuneka isasazwe kwisamente kuqala, kuba amasuntswana amancinci esamente anokususa umbane ongashukumiyo wemicu, ukuze imicu yepolypropylene isasazwe.
Xuba uze udibanise ngokulinganayo, kodwa ixesha lokuxuba akufuneki libe lide kakhulu, imizuzu eli-15 ifanelekile, kwaye isanti kunye nesamente kulula ukuzinza kwaye zibekwe ngokwahlukeneyo xa zixutywa ixesha elide.
Kuyimfuneko ukulungisa idosi yezongezo kwaye wongeze ubungakanani obufanelekileyoI-HPMCngokweenguqu zamaxesha onyaka
Kuphephe ukufunxa izinto ezongeziweyo okanye isamente.
Akuvumelekanga ngokupheleleyo ukuxuba nokusebenzisa izinto ezine-asidi.
Akuvumelekanga ukuyisebenzisa ekwakheni ngaphantsi kwe-5°C. Ulwakhiwo oluphantsi lobushushu luya kubangela ingxaki enkulu yomgangatho weprojekthi, nto leyo ebangela ukuba i-plastering mortar kunye ne-insulation board zinganamatheli. Le yingxaki yomgangatho weprojekthi ngaphandle kwesicwangciso sokulungisa kwinqanaba elilandelayo.
