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 emanzini, okuthintela ukungena kwamanzi kunye nokuphucula ukungabikho.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.
