I-Cellulose ether hpmc inomsebenzi wokugcinwa kwamanzi kunye nokuqina kwi-cement mortar kunye ne-gypsum-based mortar, enokuphucula ngokufanelekileyo ukubambelela kunye nokuchasana ngokuthe nkqo kwezinto zodaka.
Izinto ezifana nobushushu berhasi, izinga lobushushu kunye noxinzelelo lomoya zinefuthe elibi kwisantya sokuphuma komphunga kobumanzi obusuka kudaka lwesamente kunye neemveliso ezisekwe kwigypsum.Ke ngoko, kukho iiyantlukwano ekongezeni isixa esifanayo seemveliso zeHPMC ukugcina ukusebenza kakuhle kwamanzi kwixesha ngalinye lonyaka.
Ekugaleleni ikhonkrithi, umphumo wokuvala amanzi unokulungiswa ngokunyuka kunye nokunciphisa ukuhamba kwe-fractional.Izinga lokugcinwa kwamanzi kwi-methyl cellulose ether kwiqondo lokushisa eliphezulu lixabiso eliphambili lesalathisi ukuhlukanisa umgangatho we-methyl cellulose ether.
Iimveliso ze-HPMC ezikumgangatho ophezulu zinokusombulula ngokufanelekileyo ingxaki yokutshixa kwamanzi obushushu obuphezulu.Ngamaxesha okushisa aphezulu, ngakumbi kwiindawo ezishushu kunye nezifumileyo kunye nokwakhiwa kwechromatography, i-HPMC ephezulu iyafuneka ukuze kuphuculwe ukugcinwa kwamanzi kwi-slurry.
Umgangatho ophezulu we-HPMC ulungelelaniswe kakuhle kakhulu, kwaye amaqela ayo e-methoxyl kunye ne-hydroxypropyl asasazwa ngokulinganayo kwitsheyini ye-molecular cellulose, enokuphucula amandla eemolekyuli ze-oksijini ukwenza i-covalent bond kwi-hydroxyl kunye ne-ether bond.
Ingakwazi ukulawula ngokufanelekileyo ukuvela kwamanzi okubangelwa yimozulu eshushu kwaye ifezekise umphumo ophezulu wokuvala amanzi.Umgangatho ophezulu we-methylcellulose HPMC ingasetyenziswa kudaka oluxutyiweyo kunye nodaka lwemisebenzi yezandla yaseParis.
Hlanganisa zonke iinqununu eziqinileyo ukwenza ifilimu efumileyo, kwaye ukufuma kwisiqhelo kuya kukhutshwa ngokucothayo ixesha elide, kwaye uphendule ngezinto ezingaphiliyo kunye nezixhobo ze-collagen ukuqinisekisa amandla okudibanisa kunye namandla okuqina.
Ngoko ke, kwindawo yokwakhiwa kwehlobo eshushu, ukuze sifezekise umphumo wokonga amanzi, kufuneka songeze iimveliso ze-HPMC ezikumgangatho ophezulu ngokweresiphi, ngaphandle koko, kuya kubangelwa ukungabikho kokuqina, ukunciphisa amandla, ukuqhekeka, igubu legesi. kunye nezinye iingxaki zomgangatho wemveliso.Ibangela ukoma ngokukhawuleza.
Oku kwandisa nobunzima bokwakha kubasebenzi.Njengoko iqondo lobushushu lincipha, isixa se-HPMC esidityanisiweyo siyehla kancinci ukuze sifumane isiqulatho sokufuma esifanayo.
