Umgubo wepolymer ophinda uqhekeke kunye nelatex emhlophe ziintlobo ezimbini ezahlukeneyo zepolymers ezisetyenziswa kushishino lokwakha, ingakumbi kwimveliso yezinto zokwakha kunye neengubo. Nangona zombini ezi mveliso zenziwe ngezinto ezifanayo ezisisiseko, zineempawu ezahlukeneyo ezenza ukuba zilungele ukusetyenziswa ezahlukeneyo. Kweli nqaku, sihlola umahluko ophambili phakathi komgubo welatex osasazekayo kunye nelatex emhlophe kwaye sichaze ukuba kutheni zombini zizinto ezibalulekileyo kuyilo lwanamhlanje.
Okokuqala, masiqale ngezinto ezisisiseko. I-Latex yi-emulsion esekwe emanzini efana nobisi yee-polymers ezenziwe ngokwenziwa ezifana ne-styrene-butadiene, i-vinyl acetate, kunye nee-acrylics. Isetyenziswa kakhulu njenge-adhesive okanye i-adhesive ekuveliseni izinto ezahlukeneyo zokwakha, ukusuka kwi-drywall joint compound kunye ne-adhesives zethayile ukuya kwi-samente mortar kunye ne-stucco coatings. Ezona ndlela zimbini zixhaphakileyo ze-latex ezisetyenziswa ekwakheni yi-redispersible latex powder kunye ne-white latex.
Umgubo wepolymer ophinda uqhekeke, okwaziwa ngokuba yi-RDP, ngumgubo ohamba ngokukhululekileyo owenziwe ngokuxuba i-latex prepolymers, izizalisi, ii-anti-caking agents kunye nezinye izongezo. Xa ixutywe namanzi, isasazeka ngokulula ukuze yenze i-emulsion ezinzileyo, eyomeleleyo kwaye ingongezwa kwimixube eyomileyo efana nesamente okanye i-gypsum ukuphucula ukusebenza, ukunamathela kunye nokuqina. I-RDP isetyenziswa kakhulu ekuveliseni iimortars ezixutywe ngokumileyo, ii-compounds ezizilinganisayo kunye nokugqitywa okusekwe kwi-gypsum ngenxa yokugcina kwayo amanzi kakuhle, amandla kunye nokuguquguquka.
Kwelinye icala, i-latex emhlophe yi-emulsion yolwelo elungele ukusetyenziswa ye-latex yokwenziwa enokusetyenziswa ngqo kwiindawo ezimanzi njenge-adhesive, i-primer, i-sealer okanye ipeyinti. Ngokungafaniyo ne-RDP, i-latex emhlophe ayidingi kuxutywa namanzi okanye ezinye izinto ezomileyo. Inamathela kakuhle kwiintlobo ngeentlobo zezinto ezisetyenziswayo kuquka ikhonkrithi, udonga, umthi kunye nesinyithi kwaye isetyenziswa kakhulu ekuveliseni iipeyinti, ii-coating kunye ne-sealants. Ngenxa yesimo sayo solwelo, inokusetyenziswa ngokulula ngebrashi, i-roller okanye i-spray kwaye yome ngokukhawuleza ukuze yenze ifilimu engangeni manzi eqinileyo.
Ngoko ke, yintoni umahluko ophambili phakathi komgubo welatex ophinda uqhekeke kunye nelatex emhlophe? Okokuqala, zahlukile ngenkangeleko. I-RDP yipowder entle ekufuneka ixutywe namanzi ukwenza i-emulsion, ngelixa ilatex emhlophe ilulwelo olunokusetyenziswa ngqo kwiindawo eziphezu komhlaba. Okwesibini, zisetyenziswa ngokwahlukileyo. I-RDP isetyenziswa kakhulu njengesongezelelo kwimixube eyomileyo, ngelixa ilatex emhlophe isetyenziswa njengengubo okanye i-sealant. Okokugqibela, iipropati zazo zahlukile. I-RDP inika ukusebenza okugqwesileyo, ukunamathela kunye nokuguquguquka, ngelixa ilatex emhlophe inika ukumelana nokumanzi okugqwesileyo kunye nokuqina.
Kubalulekile ukuqaphela ukuba zombini i-latex powder ephinda inyibilike kunye ne-white latex zinezibonelelo kunye nokusetyenziswa kwazo okwahlukileyo. I-RDP ifanelekile ukusetyenziswa kwiimortars ezixutywe manzi kunye nezinye izinto ezisebenzisa isamente, ngelixa i-white latex ifanelekile ukusetyenziswa kwiipeyinti, ii-coating kunye ne-sealants. Nangona kunjalo, zombini ezi mveliso zinokuguquguquka kwaye zingasetyenziswa kwiintlobo ngeentlobo zezicelo, kuxhomekeke kwiimfuno ezithile zeprojekthi.
Lilonke, kubalulekile ukuqonda umahluko phakathi kweempuphu zepolymer ezisasazekayo kunye nelatex emhlophe ukuze ukhethe imveliso efanelekileyo kwisicelo sakho esithile. Zombini ezi mveliso zibonelela ngokusebenza okugqwesileyo, kwaye ngokukhetha imveliso efanelekileyo kulo msebenzi, unokuqiniseka ngeziphumo ezisemgangathweni ophezulu nezihlala ixesha elide. Njengoko itekhnoloji yelatex yokwenziwa iqhubeka ihambela phambili, kusenokwenzeka ukuba iimveliso ezintsha nezintsha ziya kuphuhliswa kwixesha elizayo eziya kwandisa uluhlu lwezicelo zezi polymers zisebenzisekayo.
