I-cellulose ether hpmc inomsebenzi wokugcina amanzi kunye nokuqina kwi-samente mortar kunye ne-gypsum-based mortar, enokuphucula ngempumelelo ukunamathela kunye nokumelana ngokuthe nkqo kwezinto ze-mortar.
Izinto ezifana nobushushu begesi, ubushushu kunye nesantya soxinzelelo lomoya zinefuthe elibi kwisantya somphunga womswakama ovela kwisamente kunye neemveliso ezisekwe kwi-gypsum. Ke ngoko, kukho umahluko othile ekongezeni inani elifanayo leemveliso ze-HPMC ukugcina ukusebenza kakuhle kwamanzi kwixesha ngalinye lonyaka.
Xa kugalelwa ikhonkrithi, isiphumo sokuvaleka kwamanzi sinokulungiswa ngokunyusa nokunciphisa ukuhamba kweqhekeza. Izinga lokugcina amanzi kwi-methyl cellulose ether kubushushu obuphezulu lixabiso eliphambili lokwahlula umgangatho we-methyl cellulose ether.
Iimveliso zeHPMC ezikumgangatho ophezulu zinokusombulula ngempumelelo ingxaki yokuvalelwa kwamanzi kubushushu obuphezulu. Ngamaxesha onyaka obushushu obuphezulu, ingakumbi kwiindawo ezishushu nezifumileyo kunye nokwakhiwa kwechromatography, iHPMC esemgangathweni ophezulu iyafuneka ukuphucula ukugcinwa kwamanzi kwi-slurry.
I-HPMC ekumgangatho ophezulu ilinganiswe kakuhle kakhulu, kwaye amaqela ayo e-methoxyl kunye ne-hydroxypropyl asasazwa ngokulinganayo kwi-molecular chain ye-cellulose, enokuphucula amandla ee-molecule ze-oxygen ukwenza ii-covalent bonds kwi-hydroxyl kunye ne-ether bonds.
Ingalawula ngempumelelo ukufuma kwamanzi okubangelwa yimozulu eshushu kwaye ifumane isiphumo esiphezulu sokuvalela amanzi. I-methylcellulose HPMC esemgangathweni ophezulu ingasetyenziswa kwi-mixed mortar kunye ne-plaster eyenziwe ngezinto zobugcisa ze-paris.
Zigqume zonke iinxalenye eziqinileyo ukuze zenze ifilimu emanzi, kwaye umswakama okwinkqubo uza kukhululwa kancinci ixesha elide, kwaye usabela kwizinto ezingaphiliyo kunye nezinto ze-collagen ukuqinisekisa amandla okubopha kunye namandla okutsalwa.
Ngoko ke, kwindawo yokwakha eshushu ehlotyeni, ukuze sifezekise isiphumo sokonga amanzi, kufuneka songeze iimveliso zeHPMC ezikumgangatho ophezulu ngokweresiphi, kungenjalo, ziya kubangelwa kukungabikho kokuqina, amandla aphantsi, ukuqhekeka, idrama yegesi kunye nezinye iingxaki zomgangatho wemveliso. Zibangela ukoma ngokukhawuleza.
Oku kwandisa ubunzima bokwakha kubasebenzi. Njengoko ubushushu busiya buncipha, ubungakanani be-HPMC eyongeziweyo buyancipha kancinci kancinci ukuze kufunyanwe umswakama ofanayo.
