Ukuthetha malunga nendima ye-latex powder ehlaziywayo kwiindawo ezahlukeneyo zodaka

I-powder ye-latex e-dispersible iyakwazi ukusabalalisa ngokukhawuleza kwi-emulsion emva kokudibanisa namanzi, kwaye ineempawu ezifanayo njenge-emulsion yokuqala, oko kukuthi, ifilimu inokuqulunqwa emva kokuba amanzi aphuke. Le filimu inokuguquguquka okuphezulu, ukuchasana kwemozulu ephezulu kunye nokuchasana neentlobo ezahlukeneyo zokubambelela kwi-substrates. Ukongeza, i-hydrophobic latex powder inokwenza udaka lungangeni manzi kakhulu.

Redispersible latex powder isetyenziswa ikakhulu ku:

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.

Indima ye-latex powder enokuphinda isetyenziswe kudaka ikakhulu kule miba ilandelayo:

1. Ukuphucula amandla oxinzelelo kunye namandla okuguquguquka kodaka.

2. Ukongezwa kwe-latex powder kwandisa ukunyuswa komdaka, ngaloo ndlela kuphuculwe ukunyanzeliswa kwempembelelo yomdaka, kwaye kuphinde kunikeze umdaka ngefuthe elihle lokusabalalisa uxinzelelo.

3. Ukuphucula ukusebenza kwebhondi yodaka. Indlela yokudibanisa isekelwe kwi-adsorption kunye nokusasazwa kwee-macromolecules kwindawo encangathi. Ngelo xesha, i-latex powder ine-permeability ethile kwaye ingena ngokupheleleyo kwisiseko sezinto ezisisiseko kunye ne-cellulose ether, ukwenzela ukuba iipropati zesiseko kunye ne-plaster entsha zisondele, ngaloo ndlela kuphuculwe i-Adsorption kwandisa kakhulu ukusebenza kwayo.

4. Ukunciphisa i-modulus elastic of mortar, ukuphucula amandla okuguqula kunye nokunciphisa i-crack phenomenon.

5. Ukuphucula ukunyanzeliswa kodaka. Ukuphuculwa kokumelana nokunxiba kubangelwa ikakhulu kubukho beglue ethile ebusweni bodaka. I-powder yeglue isebenza njengebhondi, kwaye isakhiwo se-omentum esakhiwe ngumgubo weglue sinokudlula emigodini kunye nokuqhekeka kwi-samente yodaka. Ukuphucula ibhondi phakathi kwezinto ezisisiseko kunye neemveliso zesamente ze-hydration, ngaloo ndlela kwandisa ukumelana nokunxiba.

6. Nika udaka olubalaseleyo ukuxhathisa kwealkali.

7. Ukuphucula ukudityaniswa kwe-putty, ukuchasana okugqwesileyo, ukuxhathisa kwe-alkali, ukuxhathisa ukunxiba, kunye nokuphucula amandla e-flexural.

8. Ukuphucula ukungangeni kwamanzi kunye nokungena kwe-putty.

9. Ukuphucula ukugcinwa kwamanzi kwi-putty, ukwandisa ixesha elivulekileyo, kunye nokuphucula ukusebenza.

10. Ukuphucula ukuxhathisa kwempembelelo ye-putty kunye nokwandisa ukuqina kwe-putty.

I-latex powder ephindwe kwakhona yenziwe nge-polymer emulsion ngokumisa ngokutshiza. Emva kokuxubana namanzi kumdaka, i-emulsified kwaye ihlakazwe emanzini ukuze iphinde ifake i-emulsion ye-polymer ezinzileyo. Emva kokuba i-latex powder ephinda idibaniswe i-emulsified kwaye ihlakazwe emanzini, amanzi aphuphuma. Ifilimu ye-polymer yenziwe kumdaka ukuphucula iimpawu zodaka. Umgubo welatex odityanisiweyo owahlukileyo uneempembelelo ezahlukeneyo kudaka olomileyo lomgubo.

Iipropathi zemveliso ye-latex powder ephindwe kabini

──Phucula amandla okugoba kunye namandla aguqukayo odaka

Ifilimu ye-polymer eyenziwe yi-polymer powder ephindwe kabini inokuguquguquka 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.

── 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 latex powder isasazwa kulo lonke inkqubo yodaka njengento yokuqinisa ukunyusa ukudibanisa komdaka.

──Ukuphucula ukuchasana kwempembelelo, ukuqina kunye nokuxhatshazwa kodaka

Iinqununu ze-latex ze-powder zigcwalisa i-cavity yomdaka, ubuninzi bomdaka buyanda, kwaye ukuchasana kokugqoka kuphuculwe. Ngaphantsi kwesenzo samandla angaphandle, kuya kuvelisa ukuphumla ngaphandle kokutshatyalaliswa. Ifilimu ye-polymer ingabakho ngokusisigxina kwinkqubo yodaka.

──Phucula 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.

── 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.

── Ukuphucula ukusebenza kolwakhiwo lodaka&

Kukho umphumo wokuthambisa phakathi kweepolymer latex powder particles, ukwenzela ukuba amacandelo omdaka akwazi ukuhamba ngokuzimeleyo. Ngelo xesha, i-latex powder inefuthe lokuphefumula emoyeni, inika ukunyanzeliswa kodaka kunye nokuphucula ukwakhiwa kodaka.
