IHydroxypropyl methylcellulose (HPMC) sisongezo esisebenza ngeendlela ezininzi esiqhele ukusetyenziswa kwimathiriyeli yokwakha, kubandakanywa iimveliso ezenziwe ngesamente ezifana nodaka kunye nodaka, kunye nokuncamatheliswa kweethayile kunye neegrouts. Nangona “ingawagcini” ngokuthe ngqo amanzi kwizakhiwo, idlala indima ebalulekileyo ekulawuleni ugcino lwamanzi kwezi mathiriyeli zokwakha.
Amandla okugcina amanzi: I-HPMC yi-hydrophilic, oku kuthetha ukuba inobudlelwane obuqinileyo bamanzi. Xa yongezwa kwizinto zokwakha, yenza ifilimu ebhityileyo ejikeleze amasuntswana esamente. Le filimu inceda ekubambeni amanzi ngaphakathi kwezinto eziphathekayo, ukukhusela ukuba kuphume umphunga ngokukhawuleza ngexesha lenkqubo yokunyanga. Ngenxa yoko, i-samente ingakwazi ukukhupha ngokupheleleyo kwaye iphuhlise amandla ayo, iphucula ukusebenza ngokubanzi kunye nokuqina kwezinto zokwakha.
Ukusetyenzwa: I-HPMC iphucula ukusebenza kwemathiriyeli yokwakha ngokuphucula ukungaguquguquki kunye nokunciphisa ukuthoba okanye ukudilika. Oku kubaluleke kakhulu kwizicelo ezifana nodaka kunye ne-plaster, apho izinto kufuneka zisasazeke ngokulula kwaye zigcine imilo yazo ngaphandle kokuguqulwa okugqithisileyo. Ngokulawula umxholo wamanzi kunye ne-viscosity yomxube, i-HPMC iqinisekisa ukuba izinto zihlala zilula ukuphatha kwaye zisebenzise, ziququzelele ukugqiba okugudileyo kunye okufanayo.
Ukuncitshiswa kokuNcitshiswa: Omnye wemingeni kwizinto ezisekelwe kwisamente kukucutheka ngexesha lenkqubo yokunyanga. Ukunciphisa ngokugqithiseleyo kunokukhokelela ekuqhekekeni kunye nezinye iziphene, eziphazamisa ukunyaniseka kwesakhiwo sesakhiwo. I-HPMC inceda ukunciphisa ukucutheka ngokugcina isiqulatho samanzi esingaguqukiyo kuyo yonke imathiriyeli, ukuyivumela ukuba inyange ngokulinganayo ngaphandle kokuphulukana nomthamo ogqithisileyo. Oku kubangela ukunciphisa ukuqhekeka kwe-shrinkage kunye nokuphucula ukuqina kwexesha elide lesakhiwo.
Ukuphuculwa kwe-Adhesion: Kwi-adhesives tile kunye ne-grouts, i-HPMC iphucula ukubambelela ngokuphucula amandla okudibanisa phakathi kweetayile kunye ne-substrate. Ubukho be-HPMC ekubunjweni kwe-adhesive kunceda ukudala ibhondi eqinile ngokunyusa indawo yoqhagamshelwano phakathi kwe-tile kunye ne-substrate kunye nokunciphisa umngcipheko wokuqhawula okanye ukuchithwa kwe-tile ngokuhamba kwesikhathi. Oku kubalulekile ekuqinisekiseni imfezeko kunye nobomi obude bemigangatho efakwe iithayile kwizakhiwo, ngakumbi kwiindawo ezinobumanzi obuphezulu njengezindlu zangasese kunye namakhitshi.
Ukuguquguquka okuphuculweyo: I-HPMC inokubonelela ngokuguquguquka kwezinto zokwakha, ibenze baxhathise ngakumbi ukuqhekeka kunye nokuguqulwa phantsi koxinzelelo. Oku kuluncedo ngokukodwa kwizicelo apho imathiriyeli yokwakha iphantsi kwentshukumo okanye ukungcangcazela, okufana nezinikezeli zangaphandle okanye izihluzi ezidibeneyo. Ngokuphucula ukuguquguquka kwezinto kunye nokuqina, i-HPMC inceda ukugcina ingqibelelo yesakhiwo kunye nokwandisa ubomi bayo benkonzo.
Ixesha lokumisela eliLawulwayo: I-HPMC ingasetyenziselwa ukulawula ixesha lokumisela izinto ezisekelwe kwi-samente, ukuvumela uhlengahlengiso olusekelwe kwiimfuno ezithile zeprojekthi kunye neemeko zokusingqongileyo. Ngokuguqula iimpawu ze-rheological zomxube, i-HPMC inokwandisa okanye ikhawulezise ixesha lokumisela njengoko kufuneka, inikezela ukuguquguquka kwiishedyuli zokwakha kunye nokuqinisekisa ukusebenza kakuhle kwezinto phantsi kweemeko ezahlukeneyo.
Ukumelana ne-Efflorescence: I-Efflorescence, ukufuduka kweetyuwa ezinyibilikayo kumphezulu wekhonkrithi okanye i-masonry, inokonakalisa ukubonakala kwezakhiwo kunye nokunciphisa ukuqina kwazo. I-HPMC inceda ukunciphisa i-efflorescence ngokunciphisa ukungeneka kwezinto zokwakha kunye nokunciphisa ukuhamba kwamanzi kunye neetyuwa ezinyibilikisiweyo nge-substrate. Oku kunceda ukugcina umgangatho wobuhle besakhiwo kunye nokwandisa ubomi bayo benkonzo ngokuthintela ukubunjwa kweediphozithi ezingabonakaliyo ebusweni.
I-HPMC idlala indima eninzi kwizinto zokwakha, igalelo ekugcineni amanzi, ukusebenza, ukuqina, ukunamathela, ukuguquguquka, ukubeka ixesha lokulawula, kunye nokuchasana ne-efflorescence. Ikhono layo lokuphucula ukusebenza kunye nokuphila ixesha elide lezinto zokwakha kwenza ukuba ibe yinto edityanisiweyo yokongeza kwimisebenzi yolwakhiwo lwangoku, iqinisekisa ukwakhiwa kwezakhiwo ezizinzileyo nezihlala ixesha elide.
