Ukongeza iipolymers kunokuphucula ukunganyanzeki, ukuqina, ukumelana nokuqhekeka kunye nokuchasana kwempembelelo yodaka kunye nekhonkrithi.Ukunyanzeliswa kunye neminye imiba inesiphumo esihle.Xa kuthelekiswa nokuphucula amandla e-flexural kunye namandla okudibanisa udaka kunye nokunciphisa ukunyanzeliswa kwayo, umphumo we-latex powder owenziwe ngokutsha ekuphuculeni ukugcinwa kwamanzi omdaka kunye nokuphucula ukudibanisa kwayo kulinganiselwe.
Umgubo wepolymer odispersible ngokuqhelekileyo usetyenzwa ngokutshiza ngokumisa ngokusebenzisa ezinye ii-emulsions ezikhoyo.Inkqubo kukuqala ukufumana i-polymer emulsion nge-emulsion polymerization, kwaye emva koko uyifumane ngokumisa isitshizi.Ukuthintela ukudityaniswa komgubo welatex kunye nokuphucula ukusebenza phambi kokutshiza, ezinye izongezo zihlala zongezwa, ezinje nge-bactericides, izongezo zokutshiza, iiplasticizers, defoamers, njl., ngexesha lenkqubo yokutshiza, okanye emva nje kokumisa.I-arhente yokukhululwa yongezwa ukukhusela i-clumping ye powder ngexesha lokugcina.
Ngokunyuka komxholo womgubo we-latex ophinda uhlawulwe, yonke inkqubo iphuhlisa kwiplastiki.Kwimeko yomxholo ophezulu we-latex powder, isigaba se-polymer kwi-mortar ephilisiweyo ngokuthe ngcembe idlula imveliso ye-inorganic hydration, udaka luhamba utshintsho olusemgangathweni kwaye lube ngumzimba o-elastic, kwaye imveliso ye-hydration ye-samente iba "i-filler"..Ifilim eyenziwe ngumgubo welatex odispersible osasazwe kwi-interface idlala enye indima ephambili, oko kukuthi, ukomeleza ukuncamathela kwizinto eziqhagamshelweyo, ezilungele imiphezulu enzima ukuncamathela, njengokufunxa amanzi aphantsi kakhulu okanye okungeyo- imiphezulu efunxayo (efana nekhonkrithi egudileyo kunye nesiseko semathiriyeli yesamente, iipleyiti zentsimbi, izitena ezilinganayo, umgangatho wezitena eziqinileyo, njl.njl.) kunye nomphezulu wezinto eziphilayo (ezifana neebhodi ze-EPS, iiplastiki, njl. njl.) zibaluleke kakhulu.Ngenxa yokuba i-adhesives inorganic adhesives kwi-inorganic adhesives iphunyezwa ngomgaqo wokufakela oomatshini, oko kukuthi, i-hydraulic slurry ingena kwizikhewu zezinye izinto, ngokuthe ngcembe iqina, kwaye ekugqibeleni incamathele udaka kuyo njengesitshixo esifakwe kwisitshixo.Umphezulu wezinto eziphathekayo, kulo mphezulu onzima-uku-bond, awukwazi ukungena ngokufanelekileyo ngaphakathi kwendawo yokwenza i-mechanical embedding, ukwenzela ukuba udaka olunama-adhesive kuphela angabonakaliyo alubopheli ngokufanelekileyo kuyo, kunye nokudibanisa. Indlela yepolymer yahlukile., I-polymer iboshwe kumphezulu wezinye izinto ngokusebenzisa amandla e-intermolecular, kwaye ayixhomekeke kwi-porosity yendawo (ngokuqinisekileyo, indawo enqabileyo kunye nokunyuka koqhagamshelwano kuya kuphucula ukubambelela).
