Umsebenzi osisisekos:
I-RDP Powder yi-powder emhlophe okanye emhlophe e-soluble yamanzi eveliswa ngokutshiza-yomisa i-emulsion ekhethekileyo yamanzi.
iRDP Umgubo wenza ifilimu emva kokusasazeka kwaye usebenza njengento yokuncamathela yesibini.Ti-colloid ekhuselayo ifunxwa yinkqubo yodaka (ayiyi kutshatyalaliswa ngamanzi emva kokuba ifilimu yenziwe, okanye "i-dispersion yesibili").Tyena ifilimu-eyenza i-polymer resinasa ukuqinisa imathiriyeli, isasazwa kuyo yonke inkqubo yodaka, ngaloo ndlela inyusa umanyano,tamandla acinezelayo kunye nokomelela okuguquguqukayo kodaka.
Ukongezwa kweiRDP umgubo ekwandiseni udaka kuphucula ukuqina kwempembelelo yodaka, kwaye ikwanika udaka isiphumo esihle sokusasazeka koxinzelelo.Indlela yokudibanisa ixhomekeke kwi-adsorption kunye nokusasazwa kwe-macro iimolekyuli kumphezulu oncangathi.
Kwangaxeshanye, iiRDP inomlinganiselo othile wokungena.Kanye kunye ne-ether ye-cellulose, ingena ngokupheleleyo kwisiseko sezinto ezisisiseko, ukwenzela ukuba isiseko sesiseko kunye nomphezulu we-plaster entsha sisondele ekusebenzeni kwendawo, ngaloo ndlela i-adsorbing Ukusebenza kwayo kwanda kakhulu.Nciphisa imodyuli elastic kunyeukukhubazeka-ubuchule yodaka, kwaye unciphise ukuqhekeka.
Ukuxhathisa i-abrasion yodaka:
Ukuxhatshazwa kwe-abrasion kubangelwa ubukhulu becala kubukho beglue ethile ebusweni bodaka.I-powder yerabha isebenza njenge-agent edibeneyo.Isakhiwo se-mesh eyenziwe ngumgubo werabha sinokudlula kwimingxuma kunye nokuqhekeka kwi-samente yodaka.Ukuphucula ukudibanisa kwezinto ezisisiseko kunye nemveliso ye-cement hydration, ngaloo ndlela kuphuculwe ukuxhathisa kwe-abrasion.Nika udaka olugqwesileyo ukumelana ne-alkali.
Indima yeiRDP umgubo kwi-putty, i-mortar kunye ne-tile glue:
Iputty eludongeni lwangaphakathi nangaphandle, i-adhesive tile, i-agent yokudibanisa i-tile, i-agent eyomileyo yokudibanisa i-agent, udonga lwangaphandle lwe-thermal insulation mortar, i-self-leveling mortar, udaka lokulungisa, udaka lokuhombisa, udaka olungangeni manzi kunye nodaka lwangaphandle lwe-thermal oluxubeneyo.It kukuphucula ukutyeba kunye nemodyuli eelastiki ephezulu yodaka lwesamente yemveli, kunye nokunika udaka lwesamente ukuguquguquka ngcono kunye namandla okuqina okubopha ukuxhathisa kunye nokulibazisa ukuveliswa kweentanda zodaka lwesamente.Ngenxa yokuba i-polymer kunye nodaka zenza i-interpenetrating network structure, ifilimu ye-polymer eqhubekayo yenziwa kwiipores, ezomeleza ibhondi phakathi kwee-aggregates kunye neebhloko ezinye ze-pores kwi-mortar.Ke ngoko, udaka oluqinisiweyo olulungisiweyo lusebenza ngcono kunodaka lwesamente.Kukho uphuculo olukhulu.
Indima yeiRDP umgubo kwi-putty ikakhulu kule miba ilandelayo:
1. Ukubambelela kunye neempawu zemishini ye-putty.iRDPi-powder binder eyenziwe kwi-emulsion ekhethekileyo (i-polymer ephezulu ye-molecular) isitshizi-somisiwe.Lo mgubo unokukhawulezaiphinde yachithwa-chithwa kwi-emulsion emva kokudibana 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 zokunamathela okuphezulu kwi-substrate.Ukongeza, i-latex powder egxotha amanzi inokwenza udaka lube nokuchasana kwamanzi okulungileyo.
2. Ukudityaniswa kwe-putty, ukuxhathisa okugqwesileyo, ukuxhathisa kwe-alkali, ukuxhathisa kwe-abrasion, kunye nokomelezwa kwamandla okuguquguquka.
3. Ukungangeni kwamanzi kunye nokungena kwe-putty.
4. Ukugcinwa kwamanzi kwi-putty, ukwandisa ixesha elivulekileyo, kunye nokusebenza.
5. Ukuchasana kwempembelelo ye-putty kunye nokuqina okuphuculweyo kwe-putty.
Indima yeiRDP umgubo edongeni ikakhulu kule miba ilandelayo:
1. Amandla acinezelayo kunye namandla aguquguqukayo odaka.
2. Ukongezwa kwepowder latex ekwandiseni udaka kuphucula ukuqina kwempembelelo yodaka kwaye kwakhona kunika umdaka umphumo omuhle wokusabalalisa uxinzelelo.
3. Ukusebenza kwe-bonding yodaka kuphuculwe.Indlela yokudibanisa ixhomekeke kwi-adsorption kunye nokusasazwa kweiimolekyuli ezinkulu kwindawo encangathi.Ngelo xesha, i-powder ye-rubber inomlinganiselo othile wokungena.Kanye kunye ne-ether ye-cellulose, ingena ngokupheleleyo kwisiseko sezinto ezisisiseko, ukwenzela ukuba isiseko sesiseko kunye nomgangatho we-plaster entsha sisondele ekusebenzeni kwendawo, ngaloo ndlela i-adsorbing Ukusebenza kwayo kwanda kakhulu.
4. Nciphisa imodyuli elastic kunyeukukhubazeka-ubuchule yodaka kunye nokunciphisa ukuqhekeka.
5. Nxiba ukumelana nodaka.Ukuxhatshazwa kwe-abrasion kubangelwa ubukhulu becala kubukho beglue ethile ebusweni bodaka.I-powder yerabha isebenza njenge-agent edibeneyo.Isakhiwo se-mesh eyenziwe ngumgubo werabha sinokudlula kwimingxuma kunye nokuqhekeka kwi-sement mortar.Ukuphucula ukudibanisa kwezinto ezisisiseko kunye nemveliso ye-cement hydration, ngaloo ndlela kuphuculwe ukuxhathisa kwe-abrasion.
6. Nika udaka olubalaseleyo ukuxhathisa kwealkali.
