Umphumela we-cellulose ether ekuncipheni kwepulasitiki okungenalo uthuli

1. Ucwaningo lwesizinda somphumela wei-cellulose etherekuncipheni kodaka olungenapulasitiki

I-mortar iyinto esetshenziswa kabanzi kumaphrojekthi okwakha, futhi ukuzinza kokusebenza kwayo kunomthelela obalulekile kwikhwalithi yezakhiwo. Ukuncipha okungenapulasitiki kuyinto engenzeka ku-mortar ngaphambi kokuqina, okuzobangela izinkinga ezifana nokuqhekeka ku-mortar, okuthinta ukuqina kwayo kanye nobuhle bayo. I-cellulose ether, njengesithako esivame ukusetshenziswa ku-mortar, inethonya elibalulekile ekuncipheni okungenapulasitiki ku-mortar.

2. Isimiso sokunciphisa ukuncishiswa kwepulasitiki kwamahhala kodaka nge-cellulose ether

I-cellulose ether inokugcinwa kwamanzi okuhle kakhulu. Ukulahleka kwamanzi ku-mortar kuyisici esibalulekile esiholela ekuncipheni kwe-plastic free. Amaqembu e-hydroxyl kuma-molecule e-cellulose ether kanye nama-athomu e-oxygen kuma-ether bond azokwakha izibopho ze-hydrogen nama-molecule amanzi, aguqule amanzi akhululekile abe amanzi aboshwe, ngaleyo ndlela anciphise ukulahleka kwamanzi. Isibonelo, kwezinye izifundo, kutholakale ukuthi ngokwanda komthamo we-cellulose ether, izinga lokulahlekelwa kwamanzi ku-mortar lehla ngokulandelana.i-methyl hydroxypropyl cellulose ether (HPMC), uma umthamo u-0.1-0.4 (ingxenye yesisindo), kunganciphisa izinga lokulahlekelwa amanzi kodaka lukasimende ngo-9-29%.

I-cellulose ether ithuthukisa izakhiwo ze-rheological, isakhiwo senethiwekhi embozwe yizimbobo kanye nengcindezi ye-osmotic ye-paste entsha yesimende, kanye nempahla yayo yokwenza ifilimu ivimbela ukusabalala kwamanzi. Lolu chungechunge lwezindlela luncishisa ndawonye ukucindezeleka okubangelwa izinguquko zomswakama ku-mortar, ngaleyo ndlela luvimbele ukushwabana okungenapulasitiki.

3. Umphumela womthamo we-cellulose ether ekuncipheni kwepulasitiki okungenayo ipulasitiki

Izifundo zibonise ukuthi ukuncibilika kwepulasitiki okungenayo ipulasitiki kodaka lukasimende kuncipha ngokulandelana ngokwanda komthamo we-cellulose ether. Uma sithatha i-HPMC njengesibonelo, lapho umthamo ungu-0.1-0.4 (ingxenye yobuningi), ukuncibilika kwepulasitiki okungenayo ipulasitiki kodaka lukasimende kungancishiswa ngo-30-50%. Lokhu kungenxa yokuthi njengoba umthamo ukhula, umphumela wawo wokugcina amanzi kanye neminye imiphumela yokuvimbela ukuncibilika kuyaqhubeka nokwanda.

Kodwa-ke, umthamo we-cellulose ether awukwazi ukwanda unomphela. Ngakolunye uhlangothi, ngokombono wezomnotho, ukwengeza okuningi kuzokhulisa izindleko; ngakolunye uhlangothi, i-cellulose ether eningi kakhulu ingaba nomthelela omubi kwezinye izakhiwo ze-mortar, njengamandla e-mortar.

4. Ukubaluleka kwethonya le-cellulose ether ekuncipheni kwepulasitiki okukhululekile kodaka

Ngokombono wokusetshenziswa kobunjiniyela obusebenzayo, ukwengeza okunengqondo kwe-cellulose ether ku-mortar kunganciphisa ngempumelelo ukushwabana kwepulasitiki okungenawo, ngaleyo ndlela kuncishiswe ukuvela kwemifantu ye-mortar. Lokhu kubaluleke kakhulu ekuthuthukiseni ikhwalithi yezakhiwo, ikakhulukazi ekuthuthukiseni ukuqina kwezakhiwo ezifana nezindonga.

Kweminye imisebenzi ekhethekile enezidingo eziphezulu zekhwalithi yodaka, njengezakhiwo zokuhlala ezisezingeni eliphezulu kanye nezakhiwo ezinkulu zomphakathi, ngokulawula ithonya le-cellulose ether ekuncipheni kodaka olungenapulasitiki, kungaqinisekiswa ukuthi iphrojekthi ihlangabezana nezindinganiso zekhwalithi ephezulu.

5. Amathemba ocwaningo

Nakuba kube nemiphumela ethile yocwaningo ngethonya le-cellulose ether ekuncipheni kwepulasitiki okungenayo i-mortar, kusenezici eziningi ezingahlolwa ngokujulile. Isibonelo, indlela yethonya yezinhlobo ezahlukene ze-cellulose ethers ekuncipheni kwepulasitiki okungenayo i-mortar uma zisebenza kanye nezinye izithasiselo.

Ngokuthuthuka okuqhubekayo kobuchwepheshe bokwakha, izidingo zokusebenza kwe-mortar nazo ziyanda njalo. Ucwaningo olwengeziwe luyadingeka mayelana nendlela yokulawula ngokunembile ukusetshenziswa kwe-cellulose ether ku-mortar ukuze kufezwe umphumela omuhle kakhulu wokuvimbela ukushwabana kwe-plastic free ngenkathi kucatshangelwa ezinye izakhiwo ze-mortar.
