Redispersible polymer powder (RDP) i-copolymer ye-vinyl acetate kunye ne-ethylene, esetyenziswa kakhulu njenge-binder kwizinto zokwakha. Iphucula amandla, ukuqina kunye nokubambelela kwiimveliso ezisekelwe kwi-samente ngokwenza ifilimu ezinzileyo ngexesha lokuqina. I-RDP ngumgubo omhlophe owomileyo omele usasazwe kwakhona emanzini ngaphambi kokusetyenziswa. Iipropati kunye ne-viscosity ye-RDP zizinto ezibalulekileyo njengoko zichaphazela umgangatho wemveliso yokugqibela. Eli nqaku lichaza ukusebenza kwe-RDP kunye neendlela zokuvavanya i-viscosity ezinokunceda abavelisi baphucule umgangatho wemveliso kunye nokuqinisekisa ukwaneliseka kwabathengi.
Indlela yokuvavanya ukusebenza kweRDP
Indlela yokuvavanya ukusebenza kwe-RDP yenzelwe ukuvavanya amandla e-RDP ukuphucula ukusebenza kweemveliso ezenziwe ngesamente. Inkqubo yovavanyo ngolu hlobo lulandelayo:
1. Ukulungiselela izinto eziphathekayo
Lungiselela ezi zixhobo zilandelayo: i-RDP, i-samente yasePortland, isanti, amanzi, kunye neplastiki. Hlanganisa i-samente yasePortland kunye nesanti kwisilinganiselo se-1: 3 ukufumana umxube owomileyo. Lungisa isisombululo ngokuxuba amanzi kunye neplastiki kwi-1: 1 isilinganiso.
2. xuba
Xuba i-RDP ngamanzi kwi-blender de kufumaneke i-slurry e-homogeneous. Yongeza i-slurry kumxube owomileyo kwaye udibanise imizuzu emi-2. Yongeza isisombululo seplastiki yamanzi kwaye udibanise imizuzu emi-5 eyongezelelweyo. Umxube obangelwayo kufuneka ube ne-thick, creamy consistency.
3. Faka isicelo
Ukusebenzisa i-trowel, sasaza umxube kubukhulu be-2mm kwindawo ecocekileyo, eyomileyo, ethe tyaba. Sebenzisa i-roller ukugudisa umphezulu kwaye ususe amaqamza omoya. Vumela iisampulu zinyange kwiqondo lobushushu legumbi kangangeentsuku ezingama-28.
4. Uvandlakanyo lwentsebenzo
Iisampulu ezinyangisiweyo ziye zavavanywa kwezi propati zilandelayo:
- Amandla oxinzelelo: Amandla oxinzelelo alinganiswa ngokusebenzisa umatshini wokuvavanya jikelele. Amandla oxinzelelo kufuneka abe phezulu kunesampula yokulawula ngaphandle kwe-RDP.
- Amandla e-Flexural: Amandla e-flexural alinganiswa ngokusebenzisa uvavanyo lokugoba lwamanqaku amathathu. Amandla e-flexural kufuneka abe phezulu kunesampula yokulawula ngaphandle kwe-RDP.
- Amandla okubambelela: Amandla okubambelela alinganiswa ngokusebenzisa uvavanyo lokutsala. Amandla ebhondi kufuneka abe phezulu kunesampulu yolawulo ngaphandle kwe-RDP.
- Ukumelana namanzi: Iisampulu ezinyangisiweyo zantywiliselwa emanzini iiyure ezingama-24 kwaye iipropathi zavavanywa kwakhona. Ukusebenza kwayo akufanele kuchaphazeleke kakhulu emva kokudibana namanzi.
Indlela yokuvavanya ukusebenza kwe-RDP inokubonelela ngeenjongo kunye neenkcukacha zobungakanani malunga nokusebenza kweRDP ekuphuculeni ukusebenza kweemveliso ezenziwe ngesamente. Abavelisi banokusebenzisa le ndlela yokwandisa imiqulu yeRDP kunye nokuqinisekisa umgangatho wemveliso ongaguqukiyo.
Indlela yoVavanyo lwe-RDP Viscosity
Indlela yovavanyo lwe-RDP viscosity yenzelwe ukuvavanya indlela yokuziphatha kwe-RDP emanzini. Inkqubo yovavanyo ngolu hlobo lulandelayo:
1. Ukulungiselela izinto eziphathekayo
Lungiselela ezi zixhobo zilandelayo: i-RDP, amanzi adiyoni, i-viscometer, kunye ne-calibration fluid. Uluhlu lwe-viscosity ye-calibration fluid kufuneka ifane ne-viscosity elindelekileyo ye-RDP.
2. Umlinganiselo we-Viscosity
Ukulinganisa i-viscosity ye-calibration fluid kunye ne-viscometer kwaye urekhode ixabiso. Coca i-viscometer kwaye ugcwalise ngamanzi adibeneyo. Ukulinganisa i-viscosity yamanzi kwaye urekhode ixabiso. Yongeza inani elaziwayo le-RDP emanzini kwaye ugxobhoze ngobunono de kufumaneke umxube we-homogeneous. Vumela umxube uhlale imizuzu emi-5 ukuphelisa amaqamza omoya. Ukulinganisa i-viscosity yomxube usebenzisa i-viscometer kwaye urekhode ixabiso.
3. Bala
Bala i-viscosity ye-RDP emanzini usebenzisa le fomula ilandelayo:
I-RDP Viscosity = (IViscosity yoMxube – iViscosity yaManzi) / (I-Calibration Fluid Viscosity – Viscosity yaManzi) x iCalibration Fluid Viscosity
Indlela yokuvavanya i-viscosity ye-RDP ibonelela ngesalathiso sokuba i-RDP iphinda isasazwe ngokulula kangakanani na emanzini. Ukuphakama kwe-viscosity, i-redispersibility inzima ngakumbi, ngelixa i-viscosity ephantsi, ngokukhawuleza kwaye igqibe ukuphinda iphinde iphinde iphinde iphindeke. Abavelisi banokusebenzisa le ndlela ukulungisa ukuqulunqwa kwe-RDP kunye nokuqinisekisa ukuphinda kuphinde kuphinde kuphinde kwenzeke.
ukuququmbela
Iipropati ze-RDP kunye neendlela zokuvavanya i-viscosity zizixhobo ezibalulekileyo zokuvavanya umgangatho wee-RDP kunye nokuphucula ukuqulunqwa kwazo. Ngokusebenzisa ezi ndlela, abavelisi banokuqinisekisa ukuba iimveliso zabo ze-RDP ziyahlangabezana nokusebenza okufunekayo kunye neenkcukacha ezilula zokusetyenziswa, ngaloo ndlela ukwandisa ukwaneliseka nokuthembeka kwabathengi. Abavelisi bayacetyiswa ukuba balandele iinkqubo zovavanyo olusemgangathweni kwaye basebenzise izixhobo ezilinganisiweyo ukuqinisekisa iziphumo ezichanekileyo nezithembekileyo. Njengoko iteknoloji ye-RDP iqhubeka nokuphucuka, imfuno yokusebenza okuphezulu kunye nemveliso ye-RDP ekulula ukuyisebenzisa kulindeleke ukuba yande kwixesha elizayo.
