Sechinhu chinowanzo shandiswa mumaindasitiri akasiyana, cellulose ether poda ine yakanakisa adhesion, thickening uye kuchengetedza mvura. Inoshandiswa zvakanyanya mukuvaka, mishonga, cosmetics, chikafu uye mamwe akawanda minda. Nekudaro, kuti uwane kuita kwakanakisa kubva kune cellulose ether hupfu, kutarisisa kunofanirwa kubhadharwa kune kwayo kunyungudika maitiro. Heano zvimwe zvakakosha zvekufunga nezvazvo pakunyungudutsa cellulose ether poda:
1. Sarudza mushonga wakakodzera
Cellulose ether powder inonyanya kunyunguduka mumvura, ichigadzira yakajeka, viscous solution. Nekudaro, mhando dzakasiyana dze cellulose ether dzine kunyungudika kwakasiyana mumvura, uye kunyungudika kwavo kuchakanganiswa nezvinhu zvakaita setembiricha uye pH. Naizvozvo, kusarudza solvent yakakodzera kuti uwane mhedzisiro yakakosha.
Semuenzaniso, kana cellulose ether powder inoda kunyungudutswa munzvimbo yakadzika yekushisa kana mune yakaderera pH system, hydroxypropylmethylcellulose (HPMC) kana methylcellulose (MC) inogona kuva nani kupfuura ethylcellulose (EC) kana carboxylate Zviri nani Choice Methylcellulose (CMC). Zvakakosha kusarudza mushonga wakakodzera uchifunga nezvezvinodiwa zvekushandisa uye zvimiro zvemushonga.
2. Kudzora tembiricha
Kupisa chimwe chinhu chinokosha chinokanganisa kupera kwe cellulose ether powder. Kunyungudika kwe cellulose ethers kunowedzera nekupisa, asi ndizvo zvinoitawo mwero wekunyungudika, izvo zvinogona kutungamirira kune agglomerated kana agglomerated powders. Naizvozvo, tembiricha inofanira kunyatsodzorwa panguva yekuparara.
Kazhinji, tembiricha yakakwana yekunyungudutsa cellulose ether i20-40°C. Kana kutonhora kwakanyanya kuderera, zvingave zvakakosha kuwedzera nguva yekuparara kana kushandisa imwe yakanyungudutsa yakakodzera. Kana tembiricha yakanyanyisa, inogona kukonzera kuderedzwa kwe cellulose ether uye kukanganisa kushanda kwayo.
3. Kurudzira uye fambisa
Kukurudzira uye kubvongodza kwakakoshawo pakunyungudutsa cellulose ether poda. Kubvongodza kwakakodzera kunobatsira hupfu kupararira zvakaenzana musolvent uye kunodzivirira kugwamba. Kukurudzira kunobatsirawo kuwedzera chiyero chekuparara, kunyanya kune yakakwirira viscosity mhinduro.
Nekudaro, kubvongodza kwakanyanya kunogona kuburitsa mabhuru emhepo kana furo, izvo zvinogona kukanganisa kujeka uye kugadzikana kwemhinduro. Naizvozvo, zvinodikanwa kugadzirisa kumhanyisa kumhanya uye kusimba zvinoenderana nezvinodiwa chaizvo uye nharaunda yekushandisa ye cellulose ether poda.
4. Zvinowedzera
Zviwedzerwa zvinogona kuwedzerwa panguva yekuparara kwe cellulose ether powder kuti ivandudze kushanda kwayo kana kugadzikana. Semuenzaniso, borax kana zvimwe alkaline zvinhu zvinogona kuwedzerwa kugadzirisa pH yemhinduro uye kuwedzera viscosity. Sodium bicarbonate inowedzerawo viscosity yemhinduro, inonotsa chiyero chekuparara.
Zvimwe zvinowedzera zvakaita semasurfactants, munyu kana mapolymers zvinogona kushandiswa kuwedzera kunyungudika, kugadzikana kana zvimwe zvinhu zvemushonga we cellulose ether. Zvisinei, zvakakosha kushandisa madhipatimendi pamwero uye sarudza zvakanyatsonaka, sezvo kuwedzera kana kusina kukodzera kuwedzera kunogona kukonzera zvisingadiwi migumisiro.
5. Kupedza nguva
Nguva yekuparara ndiyo inokosha parameter mukugadzirwa uye kushandiswa kwe cellulose ether powder. Nguva yekunyungudika inoenderana nezvakawanda zvinhu zvakaita serudzi rwe cellulose ether, solvent, tembiricha, kukurumidza kukurumidza uye kuisa pfungwa.
Kazhinji, cellulose ether powder inofanira kuwedzerwa kune yakanyungudutswa zvishoma nezvishoma uye zvishoma nezvishoma nekusanganiswa nguva dzose kusvikira mhinduro ine homogeneous inowanikwa. Nguva dzekuparara dzinogona kusiyana kubva pamaminitsi mashoma kusvika kumaawa akati wandei, zvichienderana nezvataurwa pamusoro.
Izvo zvakakosha kuti unyatso tarisisa nzira yekunyungudika uye kugadzirisa paramita sezvinodiwa kuti uve nechokwadi chemhando uye kuenderana kweiyo cellulose ether mhinduro.
Mukupedzisa, cellulose ether poda chinhu chakasiyana-siyana uye chakakosha mundima dzakasiyana dzeindasitiri. Nekudaro, iyo nzira yekubvisa yakakosha kuti iwane kuita kwayo kwakaringana. Nekutarisisa kune zvinhu zvakaita sekusarudza kunyungudika, kudzora tembiricha, kubvongodza, zvinowedzera, uye nguva yekunyungudika, zvinokwanisika kuwana yemhando yepamusoro cellulose ether mhinduro inosangana nezvinodiwa zvekushandisa.
