Ukuqonda ngokubanzi i-disperible polymer powder (VAE) kunye nefuthe layo kumdaka owomileyo

I-latex powder ephindwe kwakhona yenziwe nge-polymer emulsion ngokumisa ngokutshiza.Ixutywe namanzi kwi-cement mortar, i-emulsified kwaye ihlakazwe emanzini, ize iphinde ihlaziye i-emulsion ye-polymer ezinzileyo.Emva kokuba i-powder yerabha i-emulsified kwaye ihlakazwe emanzini, amanzi aphuphuma.Ifilimu ye-polymer yenziwe ngaphakathi ukuze kuphuculwe iimpawu zodaka.Umgubo welatex odityanisiweyo owahlukileyo uneempembelelo ezahlukeneyo kudaka olomileyo lomgubo.

Zeziphi iipropathi zodaka ezinokuphuculwa ngomgubo welatex ophinda uhlawulwe?

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-powder ye-rubber isetyenziswa ngokubanzi kuzo zonke iinkqubo zokulawula udaka lwe-samente ukuphucula ukudibanisa kodaka lwesamente.

4. Phucula ukuxhathisa ukwaluphala kodaka, ukuxhathisa imijikelo yokunyibilika komkhenkce, kwaye uthintele udaka lwesamente ekuqhekekeni.

I-Rubber powder yi-resin ye-thermoplastic kunye nokuguquguquka okulungileyo, okunokwenza udaka lujongane nomonakalo obangelwa yimimandla yangaphandle eshushu kunye nebanda, kwaye ngokufanelekileyo ukuphepha ukuqhekeka kumdaka ngenxa yokutshintsha kweqondo lokushisa.

5. Ukwandisa i-hydrophobicity yodaka kunye nokunciphisa umthamo womswakama

I-powder ye-rubber i-demulsifies kwi-cement mortar cavity kunye ne-surface layer, kunye nephepha le-polymer akulula ukuphinda lihlakazeke emva kokunyanga kwamanzi, ukuvimba ukungena kwamanzi kunye nokuphucula ukungazinzi.

Esona sicelo siphambili se-latex powder enokuphinda ihlakazwe:

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.

Ukusebenza kwemveliso yomgubo welatex ophinda uhlakazwe:

1. Ukuphucula amandla okugoba kunye namandla aguquguqukayo odaka

Ifilimu ye-polymer eyenziwe nguZhaojia i-polymer powder edispersible iphinde ibe nokuguquguquka okulungileyo.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-powder ye-Rubber i-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 yenza ifilimu kwisigxina sodaka kunye nomgangatho, kwaye ifilimu ye-polymer ayiyi kuphinda ihlakazeke emva kokuba ibonakaliswe emanzini, 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.
