Sechinyorwa chinowanzo shandiswa mune dzakasiyana-siyana maindasitiri, cellulose ether poda ine yakanyanya kuderera, kureruka uye kudzokorora kwemvura. Inoshandiswa zvakanyanya mukuvaka, mushonga, zvizoro, chikafu uye zvimwe zvakawanda minda. Nekudaro, kuti uwane zvakanakisa kuita kubva ku cellulose ether pody, kutariswa kunofanirwa kubhadharwa kune iyo yekunyungudika. Hezvino zvimwe zvinhu zvakakosha zvekufunga kana zvichidzika mukunyura cellulose ether poda:
1. Sarudza iyo chaiyo solvent
Cellulose ether poda inonyura mumvura, inogadzira mhinduro yechokwadi, viscous. Nekudaro, mhando dzakasiyana dze cellulose ethers dzakasiyana nemvura, uye yavo solubility ichakanganiswa nezvinhu zvakadai sekupisa uye ph. Naizvozvo, kusarudza iyo chaiyo solvent yemhedzisiro yakakwana ndeyekutsoropodza.
Semuenzaniso, kana iyo cellulose ether powder inoda kuti isimbe mune yakaderera tembiricha kana yakadzika phisheni, kana methylcellose (hpmc) kana methylcellestlose Izvo zvakakosha kusarudza solvent solidhisi inofunga nezvezvinodiwa zvekushandisa uye zvivakwa zve solvent.
2. Kudzora tembiricha
Tembiricha ndiyo imwe yakakosha consor inokanganisa kuvhiringidzika kwemasero enther poda. Iyo solubility ye cellulose aungana inowedzera ne tembiricha, asi saizvozvowo mwero wekuparadza, izvo zvinogona kutungamira kune akaomarara kana akaomeswa powders. Naizvozvo, tembiricha inofanira kunyatso kudzorwa panguva yekunyungudika.
Kazhinji, tembiricha yakakwana yekunyungudika cellulose ether ndeye 20-40 ° C. Kana tembiricha yakanyanya kuderera, inogona kunge iri madikanwa kuti uwedzere nguva yekunyungudza kana kushandisa yakafanira solvent. Kana tembiricha yakanyanya kukwirira, inogona kukonzera kusvibiswa kwemasauro ether uye kukanganisa maitiro ayo.
3. STRI uye STR
Kunzvera uye kushungurudzika kwakakoshawo kana zvichidzika mukunyura cellulose ether poda. Kushungurudzika kwakakodzera kunobatsira hupfu kuparadzira zvakanyanyisa mune solvent uye inodzivirira kudzikisira. Kumutsawo kunobatsirawo kuwedzera chiyero chekuparadzwa, kunyanya kune yakakwira viscosity mhinduro.
Nekudaro, kunyanyisa kushungurudzika kunogona kuunza mhepo mabhuru kana foam, iyo inogona kukanganisa kujekesa uye kugadzikana kwemhinduro. Naizvozvo, zvinodikanwa kuti ugadzirise kumhanya kwekukurudzira uye kusimba zvinoenderana nezvinodiwa nezvinodiwa uye zvakashanda zvinoshandiswa zvemasero ether poda.
4. Kuwedzera
Kuwedzera kunogona kuwedzerwa panguva yekunyunguduka kwemheremellose ether poda kugadzirisa maitiro ayo kana kugadzikana. Semuenzaniso, borax kana zvimwe zvinhu zveAlkaline zvinogona kuwedzerwa kugadzirisa iyo pH yemhinduro uye kuwedzera viscosity. Sodium bicarbonate zvakare inowedzera iyo visikopa yemhinduro, ichidzora mwero wekuparadzwa.
Zvimwe zvinopindwa senge surfers Nekudaro, zvakakosha kuti ushandise zvinowedzera zvine mwero uye usarudze nokungwarira, sekunyanyisa kana kusagadzikana kana zvisina kukodzera zvinogona kukonzera mhedzisiro isingadiwe.
5. Yakanyungudika nguva
Nguva yekunyungudika inguva yakakosha paramende mukugadzirwa uye kushandiswa kwe cellulose ether poda. Nguva yekunyungudika inotsamira pane zvakawanda zvinhu zvakaita senge mhando yemheremellose ether, solvent, tembiricha, inosimudzira kumhanya uye kusimbisa.
Muzhinji, cellulose ether poda inofanira kuwedzerwa kune solvent zvishoma nezvishoma uye zvishoma nezvishoma nekugara uchisangana kusvikira mhinduro yeHomogeneous inowanikwa. Nguva dzekupaza dzinogona kusiyana kubva kumaminitsi mashoma kusvika maawa akati wandei, zvichienderana nezvinhu zvataurwa pamusoro apa.
Izvo zvakakosha kutarisa kunyatsoongorora maitiro ekunyungudika uye kugadzirisa paramita sezvinodiwa kuti uve nechokwadi chekuti mhando uye kusawirirana kweiyo cellulose gadziriso.
Mukupedzisa, cellulose ether poda inzvimbo dzinoverengeka uye dzinokosha muminda dzakasiyana siyana maindasitiri. Nekudaro, maitiro ekunyungudutswa akakosha kuti azadzise kuita kwayo. Nekuteerera zvinhu zvakaita seSolvent Sarudzo, tembiricha kudzora, zvinowedzera, uye nguva yekushambadzira, zvinokwanisika kuwana yakakwira mheremalose solution inosangana nezvinodiwa zvekushandisa zvinosangana.
