I-Wall putty yimpuphu esekwe kwisamente esetyenziselwa ukulungisa kunye neendonga ezigudileyo phambi kokupeyinta okanye ukwenza iphepha lodonga. Ngokuqhelekileyo ixutywe ngamanzi okanye i-emulsion ye-polymer ukwenza i-paste enokuthi ifakwe kwiindonga. I-Wall putty yenzelwe ukuzalisa iintanda ezincinci kunye nokungafezeki kunye nokwenza umphezulu ogudileyo wokupeyinta okanye iphepha lodonga.

I-HPMC isetyenziswa njenge-thickener kwi-putty putty eludongeni ukuphucula ukusebenza kwayo kunye nokusebenza kokwakha. Yenza intlama egudileyo, enokhilimu ekulula ukuyisebenzisa kwaye isasazeke ngokulinganayo kwiindonga. I-HPMC ikwanceda ukuthintela i-putty eludongeni ekubeni igxumeke kwaye iqhekeke, iqinisekisa ukuba igudile, ide igqibe ekugqibeleni.

Enye yeenzuzo eziphambili zokusebenzisa i-HPMC njengento yokutyebisa kwi-putty eludongeni ziipropati zayo zokugcina amanzi. I-HPMC inokubamba isixa esikhulu samanzi, esinceda ukugcina i-putty eludongeni i-hydrated kwaye isebenze ixesha elide. Oku kwenza kube lula ukufaka isicelo kwaye kuvumela umsebenzisi ixesha elingakumbi lokusebenza ngemathiriyeli ngaphambi kokuba iqale ukuseta.

HPMC kwakhona iphucula ancamathele eludongeni putty eludongeni. Idala umanyano olomeleleyo phakathi kwe-putty kunye nodonga, iqinisekisa ukuba ihlala kwindawo kwaye ayiqhekezi okanye ixoke ngokuhamba kwexesha. HPMC kwakhona amanzi kunye nemichiza ukumelana, nto leyo enceda ukukhusela iindonga kwaye ubanike egudileyo, inkangeleko flat.

Olunye uncedo lokusebenzisa i-HPMC njenge-thickener kwi-putty eludongeni kukuhambelana kwayo nezinye izongezo. Ingasetyenziswa kunye nezinye izinto ezahlukeneyo, kubandakanywa ii-pigments, izihluzi kunye nezinye i-thickeners, ukudala ukwakheka kodonga lwe-putty oluhlangabezana neemfuno ezithile zesicelo.

Ngaphandle kokusetyenziswa kwayo njengento etyebisayo kwi-putty eludongeni, i-HPMC inezinye izicelo ezininzi zemizi-mveliso. Isetyenziswa njenge-binder, i-emulsifier kunye ne-stabilizer kwiimveliso ezahlukeneyo, kubandakanywa ukutya, amayeza, izithambiso kunye neemveliso zokunyamekela. Ikwasetyenziswa njenge-ejenti yokuqina kwi-adhesives, i-coatings kunye ne-sealants.

Ngokubanzi, i-HPMC lolona khetho lubalaseleyo njenge-thickener yeputty eludongeni. Inika uluhlu lweenzuzo ezibandakanya ukuphuculwa kwenkqubo, ukugcinwa kwamanzi, ukunamathela kunye nokuhambelana nezinye izongezo. Ikwafumaneka ngokulula kubavelisi abaninzi abakhokelayo, beyenza ibe yimveliso efanelekileyo nengabizi kakhulu.
