I-redispersible latex powder, eyaziwa ngokuba yi-redispersible polymer powder (RDP), yipolymer powder eveliswa ngokutshiza ukomisa i-latex yamanzi. Isetyenziswa ngokuqhelekileyo njengesongezo kwizinto ezahlukeneyo zokwakha, kuquka udaka. Ukongeza umgubo we-latex owenziwe kwakhona kwi-mortars unikezela ngeenzuzo ezahlukeneyo, kubandakanywa ukubambelela okuphuculweyo, ukuguquguquka, ukuxhathisa kwamanzi kunye nokusebenza ngokubanzi.
A. Iimpawu zomgubo welatex ophinda uhlakazwe:
1.Ukwakheka kwePolymer:
Redispersible latex powder ngokuqhelekileyo iqulunqwe iipolima ezahlukeneyo, ezifana vinyl acetate-ethylene (VAE), vinyl acetate-ethylene carbonate (VeoVa), njl.
2. Ubungakanani besuntswana:
Ubungakanani be-particle ye-latex powder edibeneyo ibaluleke kakhulu kwi-dispersibility yayo kunye nokusebenza kwizicelo ezahlukeneyo. Amaqhekeza ahlulwe ngokucokisekileyo aqinisekisa ukusasazeka lula emanzini ukwenza i-emulsions ezinzile.
3. I-Dispersibility:
Enye yeempawu eziphambili zale powder kukuphinda kuphindwe kwakhona. Emva kokuba ixutywe namanzi, yenza i-emulsion ezinzileyo efana ne-latex yasekuqaleni, ibonelela ngeenzuzo ze-latex yamanzi kwifom ye powder.
B. Indima yomgubo welatex odityanisiweyo kudaka:
1. Phucula ukuncamathelisa:
Ukongezwa komgubo welatex ohlakazekayo kwiidaka kwandisa ukunamathela kwiintlobo ezahlukeneyo zesubstrates, kubandakanywa ikhonkrithi, i-masonry kunye neethayile ze-ceramic. Olu phuculo lokubambelela lunceda ukuphucula amandla onke kunye nokuqina kodaka.
2. Ukwandisa ukuguquguquka:
Udaka olulungiswe ngomgubo welatex oludispersible lubonisa ukuguquguquka okuphezulu. Oku kunenzuzo ngakumbi kwiimeko apho i-substrate inokufumana ukunyakaza okuncinci okanye ukwandiswa kwe-thermal kunye nokunciphisa.
3. Ukungangeni manzi:
Redispersible latex powder inika ukuxhathisa kwamanzi ngodaka. Oku kubalulekile kwizicelo apho udaka lusesichengeni samanzi okanye ukufuma, njengakwinkqubo yangaphandle okanye kwindawo efumileyo.
4. Nciphisa ukuqhekeka:
Ukuguquguquka okubonelelwa ngumgubo we-latex owenziwe ngokutsha kunceda ukunciphisa amathuba okuqhekeka kodaka. Oku kubaluleke ngakumbi kwizicelo apho iintanda zinokubeka esichengeni imfezeko yesakhiwo.
5. Ukuqhubekeka okuphuculweyo:
Udaka oluqulathe umgubo welatex ophinda lichitheke lubonisa ukusebenza kakuhle okuphuculweyo, nto leyo eyenza kube lula ukuphatha nokwakha. Oku kunokuba yingenelo xa kusakhiwa.
6. Ukuhambelana nezinye izongezo:
I-latex powder ephinda isetyenziswe iyahambelana neentlobo zezinye izongezo ezisetyenziswa ngokuqhelekileyo kwimiqulu yodaka. Oku kuguquguquka kuvumela ukusebenza kodaka ukuba kulungiselelwe iimfuno ezithile zeprojekthi.
C. Izinto eziluncedo zokusebenzisa umgubo welatex odispersible kudaka:
1. Ukuguquguquka:
Redispersible latex powder isetyenziswa kakhulu kwaye ingasetyenziswa kwiindidi ezahlukeneyo zodaka, kubandakanywa udaka oluseti olucekethekileyo, udaka lokulungisa, kunye nodaka olungenamanzi.
2. Ukomeleza ukuqina:
Udaka olulungisiweyo lunika ukuqina okukhulu kwaye lufanelekile kwizicelo ezibango apho ubomi obude bubaluleke kakhulu.
3. Ukusebenza okuzinzileyo:
Inkqubo yokuvelisa elawulwayo ye-latex powder edibeneyo iqinisekisa ukusebenza okuhambelanayo, okukhokelela kwiziphumo eziqikelelwayo kwizicelo zodaka.
4. Ukusebenza kakuhle kweendleko:
Ngelixa iindleko zokuqala ze-latex powder ezihlaziywayo zinokuba phezulu kunezongezo zendabuko, iipropati eziphuculweyo ezinikezela kumdaka zingakhokelela ekugcinweni kweendleko zexesha elide ngokunciphisa imfuno yokulungiswa nokugcinwa.
5. Iingqwalasela zokusingqongileyo:
I-latex powder esekelwe emanzini i-disperible latex powder ihambelana nokusingqongileyo kunezinye iindlela ezisekelwe kwi-solvent. Banegalelo kwimisebenzi yokwakha ezinzileyo.
I-latex powder edibeneyo i-redispersible i-addispersible i-addispersible kwi-formulation ye-mortar, inikezela uluhlu lweenzuzo ezifana nokuphucula ukubambelela, ukuguquguquka, ukuchasana kwamanzi kunye nokunciphisa ukuqhekeka. Ukuguquguquka kwayo kunye nokuhambelana nezinye izongezo zenza ukuba kube yinto yokuqala yokukhethwa kwezicelo zokwakha ezahlukeneyo. Ngokuphucula iimpawu zodaka, i-disperible latex powder inceda ukuphucula ukuqina kunye nokusebenza kwezinto zokwakha, okwenza kube sisixhobo esibalulekileyo kwimisebenzi yokwakha yanamhlanje.
