I-Hydroxypropyl methylcellulose isetyenziswa kakhulu njenge-dispersant ekuvelisweni kwe-polyvinyl chloride, kwaye yeyona nto incedisayo ekulungiseleleni i-PVC nge-suspension polymerization. Kwinkqubo yokwakha kwishishini lokwakha, isetyenziswa kakhulu kwizakhiwo ezisebenzisa oomatshini ezifana nokwakha udonga, ukuplasta, ukugquma, njl.njl.; ingakumbi kwizakhiwo zokuhombisa, isetyenziselwa ukuncamathisela iithayile ze-ceramic, imabula, kunye nemihombiso yeplastiki. Inamandla aphezulu okubopha kwaye inokunciphisa ubungakanani besamente. . Isetyenziswa njengesithambisi kwishishini lokupenda, esinokwenza umaleko ukhanye kwaye ube buthathaka, sithintele ukususwa komgubo, siphucule ukusebenza kwe-leveling, njl.njl.
Kwi-samente mortar kunye ne-gypsum-based slurry, i-hydroxypropyl methylcellulose idlala indima yokugcina amanzi kunye nokuqina, nto leyo enokuphucula ngempumelelo amandla adibeneyo kunye nokumelana nokuwa kwe-slurry. Izinto ezifana nobushushu bomoya, ubushushu kunye nesantya soxinzelelo lomoya ziya kuchaphazela izinga lokuguquguquka kwamanzi kwi-samente mortar kunye neemveliso ezisekelwe kwi-gypsum. Ke ngoko, ngamaxesha ahlukeneyo onyaka, kukho umahluko othile kwisiphumo sokugcina amanzi kwiimveliso ezinomlinganiselo ofanayo we-hydroxypropyl methylcellulose eyongeziweyo. Kulwakhiwo oluthile, isiphumo sokugcina amanzi se-slurry sinokulungiswa ngokunyusa okanye ukunciphisa inani le-HPMC eyongeziweyo. Ukugcinwa kwamanzi kwe-methyl cellulose ether phantsi kweemeko zobushushu obuphezulu luphawu olubalulekileyo lokwahlula umgangatho we-hydroxypropyl methyl cellulose ether. Iimveliso ezibalaseleyo ze-hydroxypropyl methylcellulose series zinokusombulula ngempumelelo ingxaki yokugcina amanzi phantsi kobushushu obuphezulu. Ngexesha lobushushu obuphezulu, ngakumbi kwiindawo ezishushu nezomileyo kunye nokwakhiwa okuncinci kwicala elinelanga, i-HPMC esemgangathweni ophezulu iyafuneka ukuphucula ukugcinwa kwamanzi kwe-slurry.
I-hydroxypropyl methylcellulose (HPMC) ekumgangatho ophezulu inobunye obuhle kakhulu. Amaqela ayo e-methoxy kunye ne-hydroxypropoxy asasazwa ngokulinganayo kwi-cellulose molecular chain, enokunyusa ii-athomu ze-oxygen kwi-hydroxyl kunye ne-ether bonds. Amandla okunxulumana namanzi ukwenza ii-hydrogen bonds aguqula amanzi akhululekileyo abe ngamanzi abotshelelweyo, ngaloo ndlela elawula ngempumelelo ukufuma kwamanzi okubangelwa yimozulu ephezulu yobushushu kwaye afezekise ukugcinwa kwamanzi okuphezulu. Amanzi ayimfuneko ukuze kufakwe amanzi ukuze kufakwe izinto eziqinisayo ezifana nesamente kunye ne-gypsum. Ubungakanani obuchanekileyo be-HPMC bunokugcina umswakama kwi-mortar ixesha elide ngokwaneleyo ukuze inkqubo yokubeka kunye nokuqina iqhubeke.
Ubungakanani be-hydroxypropyl methylcellulose (HPMC) obufunekayo ukuze kufunyanwe ukugcinwa kwamanzi okwaneleyo buxhomekeke koku kulandelayo:
Ukufunxwa komaleko wesiseko
Ukwakhiwa kweMortar
Ubukhulu bomaleko wesamente
Imfuneko yamanzi odaka
Ixesha lokubekwa kwezinto ezisetyenziswa ngesamente
I-Hydroxypropyl methylcellulose inokusasazeka ngokulinganayo nangokufanelekileyo kwi-samente mortar kunye neemveliso ezisekwe kwi-gypsum, kwaye igqume zonke iinxalenye eziqinileyo, kwaye yenze ifilimu yokumanzisa, umswakama kwisiseko ukhutshwa kancinci kancinci ixesha elide, kwaye uyahambelana ne-inorganic. Impendulo yokufunxa amanzi kwezinto ezifakwe kwi-gel iqinisekisa amandla okubopha kunye namandla okucinezela kwezinto.
Ngoko ke, kulwakhiwo lwasehlotyeni olushushu kakhulu, ukuze kufezekiswe isiphumo sokugcina amanzi, kuyimfuneko ukongeza iimveliso ze-HPMC ezikumgangatho ophezulu ngobuninzi obaneleyo ngokwefomula, kungenjalo, kuya kubakho ukufuma okwaneleyo, amandla anciphileyo, ukuqhekeka, ukugoba kunye nokuchitheka okubangelwa kukoma kakhulu. kodwa kwanokwandisa ubunzima bokwakha babasebenzi. Njengoko ubushushu busiya buhla, ubungakanani bamanzi ongezelelweyo e-HPMC bunokuncipha kancinci kancinci, kwaye isiphumo esifanayo sokugcina amanzi sinokufezekiswa.
