Zeziphi iipropathi zodaka ezinokuphuculwa ngomgubo welatex ophinda uhlawulwe?
I-latex i-powder e-dispersible yenziwe nge-polymer emulsion ngokumisa i-spray, ixutywe namanzi kumdaka we-samente, i-emulsified kwaye ihlakazeke emanzini, kwaye emva koko ivuselela i-emulsion ye-polymer ezinzileyo. Emva kokuba i-latex i-powder e-dispersible i-emulsified kwaye ihlakazwe emanzini, amanzi aphuphuma , Yenza ifilimu ye-polymer kwi-mortar ukuphucula iimpawu zodaka. Umgubo welatex odityanisiweyo owahlukileyo uneempembelelo ezahlukeneyo kudaka olomileyo lomgubo.
1. Ukuphucula ukuchasana kwempembelelo, ukusebenza kunye nokuxhatshazwa kokugqoka komdaka
Umdaka ugcwele i-cement mortar pore cavity, i-compactness ye-cement mortar iphuculwe, kwaye ukuxhatshazwa kokugqoka kuphuculwe. Ngaphantsi kwesenzo samandla angaphandle, kunokubangela ukuphumla ngaphandle kokutshatyalaliswa. Iphepha lepolymer linokugcinwa kwinkqubo yokulawula udaka lwesamente.
2. Ukuphucula ukubambelela kolwakhiwo lodaka
I-polymer powder particles inefuthe lokumanzisa, ukwenzela ukuba amacandelo amabini omdaka we-samente angakwazi ukuhamba ngokuzimeleyo. Ukongezelela, i-powder ye-rubber inefuthe lokunyusa igesi.
3. Ukuphucula ukudibanisa amandla oxinzelelo kunye namandla adibeneyo odaka
Njengokuncamathelisa kweekhemikhali zendalo, i-latex powder ephinda ikwazi ukuvelisa amandla aphezulu oxinzelelo kunye namandla oxinzelelo kwiibhodi ezahlukeneyo. Idlala indima ebaluleke kakhulu ekudibaneni kodaka lwesamente kunye nezixhobo ze-organic chemical raw (isisu, ibhodi ye-foam ekhutshiweyo ekhutshiweyo) kunye nomphezulu webhodi yokucoca. I-DEM izinto eziluhlaza kunye ne-polymer depilatory powder zisetyenziswa ngokubanzi kuzo zonke iinkqubo zokulawula udaka lwesamente ukuphucula ukudibanisa kodaka lwesamente.
4. Phucula ukuxhathisa ukwaluphala kodaka, ukuxhathisa imijikelo yokunyibilika komkhenkce, kwaye uthintele udaka lwesamente ekuqhekekeni.
I-redispersible latex powder yi-resin ye-thermoplastic ene-flexibility efanelekileyo, enokwenza udaka lujongane nomonakalo obangelwa ukushisa kwangaphandle kunye neendawo ezibandayo, kwaye ngokufanelekileyo ugweme ukuqhekeka kumdaka ngenxa yokutshintsha kweqondo lokushisa.
5. Ukwandisa i-hydrophobicity yodaka kunye nokunciphisa umthamo womswakama
I-latex powder ehlaziywayo i-demulsified kwi-sement mortar cavity kunye ne-surface layer, kunye nephepha le-polymer akulula ukuphinda lihlakazeke emva kokunyanga kwamanzi, ukuthintela ukungena kwamanzi kunye nokuphucula ukungazinzi. Obu boya beglasi obungangeni manzi bunesiphumo esingcono ngenxa yesakhono saso esisodwa sokusasaza umgubo wendalo welatex.
Ukusetyenziswa okuphambili kwe-latex powder edibeneyo
Iputty eludongeni lwangaphakathi nangaphandle, i-adhesive yethayile, i-agent ekhomba i-tile, i-agent eyomileyo yokudibanisa i-ejenti, i-thermal insulation mortar yangaphandle yeendonga zangaphandle, i-self-leveling mortar, udaka lokulungisa, udaka lokuhombisa, udaka olungangeni manzi lwangaphandle lwe-thermal edibeneyo eyomileyo exutywe nodaka. Kumda, kukuphucula i-brittleness, imodyuli ephezulu e-elastiki kunye nobunye ubuthathaka bodaka lwesamente lwemveli, kunye nokunika udaka lwesamente ngokuguquguquka okungcono kunye namandla okuqina kwebhondi, ukwenzela ukuxhathisa kunye nokulibazisa ukuveliswa kweentanda zodaka lwesamente. Ekubeni i-polymer kunye nodaka lwenza i-interpenetrating network structure, ifilimu ye-polymer eqhubekayo yenziwa kwiipores, eyomeleza ukudibanisa phakathi kwee-aggregates kunye neebhloko ezinye ii-pores kumdaka, ngoko udaka olulungisiweyo emva kokuqina lungcono kunodaka lwesamente. Kukho uphuculo olukhulu.
Iipropathi zemveliso ye-latex powder ephindwe kabini
1. Ukuphucula amandla okugoba kunye namandla aguquguqukayo odaka
Ifilimu ye-polymer eyenziwe ngumgubo we-latex owenziwe ngokutsha unokuguquguquka okuhle. Iifilimu zenziwe kwizikhewu kunye nomgangatho wamasuntswana odaka lwesamente ukwenza unxibelelwano oluguquguqukayo. Udaka lwesamente olunzima noluphukayo luba ilastiki. Udaka olongeziweyo ngomgubo we-latex oludispersible luphindaphindeka kaninzi kwi-tensile kunye nokumelana nokuguquguquka kunodaka oluqhelekileyo.
2. Ukuphucula amandla okudibanisa kunye nokudityaniswa kodaka
Emva kokuba i-latex powder ephinda ihlakazwe njenge-organic binder yenziwe ifilimu, inokwenza amandla aphezulu kunye namandla okudibanisa kwii-substrates ezahlukeneyo. Idlala indima ebalulekileyo ekunamatheleni komdaka kwizinto eziphilayo (i-EPS, ibhodi ye-foam ekhutshweyo) kunye ne-substrates egudileyo. Ifilimu ye-polymer ye-polymer powder isasazwa kulo lonke inkqubo yodaka njengento yokuqinisa ukunyusa ukudibanisa komdaka.
3. Ukuphucula ukuchasana kwempembelelo, ukuqina kunye nokuxhatshazwa kokugqoka komdaka
Iinqununu ze-rubber ze-powder zigcwalisa i-cavity ye-mortar, ubuninzi bomdaka buyanda, kwaye ukuxhatshazwa kokugqoka kuphuculwe. Ngaphantsi kwesenzo samandla angaphandle, kuya kuvelisa ukuphumla ngaphandle kokutshatyalaliswa. Ifilimu ye-polymer ingabakho ngokusisigxina kwinkqubo yodaka.
4. Ukuphucula ukuxhathisa kwemozulu kunye nokumelana nokunyibilika kodaka, kwaye uthintele udaka ekuqhekekeni
I-redispersible latex powder yi-resin ye-thermoplastic ene-flexibility efanelekileyo, enokwenza udaka lukwazi ukujamelana nokutshintsha kwendawo ebandayo yangaphandle kunye neshushu, kwaye ikhusele ngokufanelekileyo udaka ekuqhekekeni ngenxa yokutshintsha kweqondo lokushisa.
5. Ukuphucula i-hydrophobicity yodaka kunye nokunciphisa ukufunxa kwamanzi
I-latex powder ehlaziywayo yenza ifilimu kwi-cavity kunye nomgangatho womdaka, kwaye ifilimu ye-polymer ayiyi kuphinda ihlakazeke emva kokuba ibonakaliswe kumanzi, okuthintela ukungena kwamanzi kunye nokuphucula ukungabonakali. I-latex ekhethekileyo ye-latex powder enefuthe le-hydrophobic, i-hydrophobic effect engcono.
6. Ukuphucula ukusebenza kolwakhiwo lodaka
Kukho umphumo wokuthambisa phakathi kweepuphu ze-polymer rubber powder, ukwenzela ukuba amacandelo omdaka akwazi ukuhamba ngokuzimeleyo. Ngelo xesha, i-powder ye-rubber inempembelelo yokuphefumula emoyeni, inika ukunyanzeliswa kodaka kunye nokuphucula ukwakhiwa kodaka.
