Redispersible latex powder (RDP)ngumgubo wepolymer onokuphinda uhlakazwe oveliswe ngetekhnoloji yokutshiza yokumisa. Inokubambelela kakuhle, ukuguquguquka, ukuchasana nokuqhekeka kunye nokuchasana kwamanzi, kwaye isetyenziswa ngokubanzi kwizinto zokwakha. phakathi. I-EPS (i-polystyrene eyandisiweyo) i-thermal insulation mortar yinto ekhaphukhaphu yokugquma kwe-thermal eyenziwe ngamasuntswana e-EPS njengeaggregate ekhaphukhaphu, isamente njengemathiriyeli yesamente, kunye nezinye izongezo. Ukwazisa umgubo we-latex odispersible kwi-EPS yokugquma udaka kunokuphucula ngokubonakalayo iimpawu zayo zomzimba kunye noomatshini kunye nokusebenza kolwakhiwo.
1. Indlela yokusebenza ye-latex powder edispersible kwi-EPS insulation mortar
Njengomathiriyeli wepolymer, i-RDP yenza ifilimu yepolymer eqhubekayo ngokusasazwa kwakhona ngexesha lenkqubo yokufakwa kwamanzi. Le filimu inokugqoka iinqununu zezinto ze-cementitious, i-aggregates lightweight kunye neengqungquthela ze-EPS kumdaka, ngaloo ndlela uphucula amandla okudibanisa phakathi kwamacandelo. Ukongeza, iifilimu ze-polymer zinokuzalisa i-micro-cracks kunye ne-pores kwi-mortar, ngaloo ndlela iphucula ukubumbana kwezinto kunye nokungagungqi. Iimpawu eziguquguqukayo ze-RDP zinceda ukunciphisa ingxaki yokuqhekeka kwe-EPS yokugquma udaka olubangelwa ukuhluka kweqondo lokushisa okanye utshintsho lomthwalo.
2. Impembelelo ekusebenzeni kwe-EPS insulation mortar
(1) Ukuphucula amandla okudibanisa
Ukuqaliswa kwe-RDP kunokuphucula ngokubonakalayo amandla okudibanisa kwe-EPS yokugquma udaka. Ukuqulunqwa kwefilimu ye-polymer akugcini nje ukwandisa amandla okubambisana phakathi kweengqungquthela ze-EPS kunye ne-matrix, kodwa kwakhona kuphucula ukusebenza kokubambisana phakathi kodaka kunye nodonga olusisiseko, ngaloo ndlela ukunciphisa umngcipheko wokulahla nokuphucula ukuqina kwenkqubo.
(2) Ukomeleza ukuxhathisa kokuqhekeka
NgokubaiRDPinokuguquguquka okuhle, ifilimu yepolymer eyenziwe yiyo inokuthintela ngokufanelekileyo uxinzelelo loxinzelelo kunye nokulibazisa ukwandiswa kwee-microcracks. Uphando lubonisa ukuba amandla okuguquguquka kunye neepropathi zokuqina kwe-EPS yokugquma udaka oluxutywe nesixa esifanelekileyo se-RDP ziphuculwe kakhulu, ezinceda ekuphuculeni ukuxhathisa kokuqhekeka kodaka.
(3) Ukuphucula ukusebenza kolwakhiwo
I-RDP inokuphucula ukusebenza kunye nokugcinwa kwamanzi kwi-EPS yokugquma udaka kunye nokuphucula amava okusebenza ngexesha lenkqubo yokwakha. Iimpawu zayo zokugcina amanzi zinceda ukulibazisa ukulahleka kwamanzi odaka, ngaloo ndlela iqinisekisa ukuba isiseko sesiseko sigcwele ngokupheleleyo kwaye siphucula amandla okuqala.
(4) Ukomeleza ukuqina
Ukuchasana kwamanzi kunye neekhemikhali zefilimu ye-RDP kuphucula kakhulu ukuxhatshazwa kwe-freeze-thaw kunye nokumelana ne-carbonation ye-EPS yokugquma udaka. Oku kubaluleke kakhulu ekusebenzeni kwexesha elide lezinto eziphathekayo.
(5) Utshintsho oluphakathi kubuninzi
Ukuqaliswa kwe-RDP kunempembelelo encinci kubuninzi bodaka, kodwa ukuphuculwa kwamandla oxinzelelo kufuna ukulawula idosi. Ukugqithisa kwe-RDP kunokukhokelela ekwehleni kokumelana noxinzelelo, ngoko ke umlinganiselo kufuneka uphuculwe ngokufanelekileyo ngelixa usanelisa ezinye iipropathi.
3. Ukubaluleka kwezobunjineli
Kwizicelo zobunjineli bokwenyani, i-EPS yokugquma udaka kufuneka ibe nazo zombini ukugquma kwe-thermal kunye neempawu zoomatshini, ngelixa ihlangabezana neemfuno zolwakhiwo olulula kunye nokuqina okuphezulu. Njengolungiso oluphambili, i-latex powder ehlaziywayo ibonelela ngezisombululo ezininzi zokuphucula ukusebenza kwe-EPS yokugquma udaka. Ngakolunye uhlangothi, ukusetyenziswa kwe-RDP kuphucula kakhulu ukubambelela kunye nokuchasana kokuqhekeka komdaka kunye nokunciphisa umngcipheko wokuwa kwe-insulation layer kunye nokuqhekeka; kwelinye icala, ukuphuculwa kwayo kumsebenzi wokwakha kunye nokuqina kodaka kwenza i-EPS yokugquma udaka ifaneleke ngakumbi kwiiprojekthi zokonga umbane ezikumgangatho ophezulu.
I-latex powder enokuchithwa kwakhonainokuphucula kakhulu ukusebenza kwebhondi, ukumelana nokuqhekeka, ukusebenza kolwakhiwo kunye nokuqina kwe-EPS yokugquma udaka ngokwenza ifilimu yepolymer. Kwizicelo zobunjineli, ukulungelelaniswa okunengqiqo komthamo kunye nokusetyenziswa kwe-RDP kunokufikelela eyona ntsalela ilungileyo yezinto eziphathekayo. Uphando lwexesha elizayo lunokuphonononga ngakumbi intsebenziswano phakathi kwe-RDP kunye nezinye izilungisi ukuhlangabezana neemfuno zodaka lokufakwa kwe-thermal kwiimeko ezahlukeneyo.
