Iyo inonyanya kukosha pfuma ye cellulose ether yekuchengetedza kwayo kwemvura muzvivakwa zvekuvaka. Pasina kuwedzerwa kweCellulose ether, iyo danda rakatetepa retsva rinofamba nekukurumidza kuti simende isingakwanisi kuomesa nenzira yakajairika uye durari haigoni kuomesa uye kuwana hukama hwakanaka. Panguva imwecheteyo, kuwedzera kwe cellulose ether kunoita kuti durasiramu yakanaka uye kuchinjika, uye inovandudza simba rekubatanidza remutya. Ngatitaurei nezvekuchinja kwekushandisa kwekushandiswa kwekuoma-kwakasanganiswa kubva pakuita kwechigadzirwa kwekuita cellulose ether.
1. Iyo yakajeka ye cellulose ether
Iyo yakajeka ye cellulose ether inokanganisa iyo solubility. Semuenzaniso, iyo yakadzika iyo yakaderera ye cellulose ether, iyo inokurumidza inopaza mumvura uye kuvandudzwa kwekuita kwemvura kwekuita kwemvura. Naizvozvo, iyo yakajeka ye cellulose ether inofanira kuverengerwa seimwe yezvivakwa zvayo zvekuferefeta. Kazhinji kutaura, iyo Sieve yakasara yemasero ether ineness inopfuura 0.212mm haifanire kupfuura 8.0%.
2. Kuomesa uremu kurasikirwa chiyero
Kuomesa uremu kurasikirwa kwehuremu kunoreva nezve chikamu chehuwandu hwezvinhu zvakarasika muhuwandu hwehukuru hwenguva yekutanga kana iyo cellulose ether yaoma pane imwe tembiricha. Kune mumwe mhando ye cellulose ether, iyo yekuomesa hurema chiyero yakanyanya, iyo ichaderedza zvirimo zvechinongedzo muCellulose Ethersnstons embiritsi, uye wedzera mutengo wekutenga. Kazhinji, kurasikirwa kwehuremu pakuomesa cellulose ether hakusi kupfuura 6.0%.
3. Sulfate ASH zvemukati weCellulose ether
Kune mumwe mhando ye cellulose ether, iyo ASH zvemukati yakanyanya, iyo ichaderedza zvirimo zvine chekuita nemheremalose ether uye kukanganisa maitiro ekunyorera emubhedha ekusarudza. Iyo sulfate ASH zvemukati zvemasero ether chiitiko chakakosha chekuita kwayo. Yakasanganiswa neyazvino yekugadzira mamiriro emugwagwa wangu aripo cellulose Cellucose Vagadziri veMC, HPMC, HPMC haifanirwe Kupfuura 2,5% yeHEC Cellaulose ether haifanire kupfuura 10.0%.
4. Viscosity ye cellulose ether
Kuchengetwa kwemvura uye kukonzeresa kwemasero e cellulose ether inonyanya kuenderana neiyo viscosity uye dosage yemasero yekucheka pachayo yakawedzerwa kune simende slumry.
5. Iyo PH kukosha kwe cellulose ether
Iyo viscosity yeCellulose zvigadzirwa zvinodzikira zvishoma nezvishoma ichadzikira mushure mekuchengeterwa tembiricha kana kwenguva yakareba, kunyanya yezvigadzirwa zvepamusoro-miganhu, saka zvakafanira kudzikamisa iyo pH. Kazhinji, zvinokurudzirwa kudzora iyo PH Range ye cellulose ether kusvika 5-9.
6. Chiedza chinoputika che cellulose ether
Iyo mwenje yekuputika ye cellulose ether inobata zvakananga zvinokanganisa kushanda kwayo mukuvaka. Izvo zvinhu zvikuru zvinokanganisa mwenje wekuputika weCellulose ether ari: (1) mhando yezvinhu zvisina kugadzirwa; (2) mhedzisiro yeayo. (3) maitiro akawedzera; (4) solvent ratio; (5) kusaruramisa maitiro.
Zvinoenderana nekushandiswa kweshandisirwo, kujekesa kwechiedza che cellulose ether hakufanirwe kunge zvisingasviki 80%.
7. Iko kupisa kweGel ye cellulose ether
Cellulose ether inonyanya kushandiswa seViscotifier, Plticsezer uye Wemvura Yekutungamira mumidziyo yezvigadzirwa, saka viscosity uye tembiricha miganho yakakosha kuti uwane hunhu hwe cellulose ether. Iyo tembiricha yeGel inoshandiswa kuona mhando ye cellulose ether, iyo ine hukama neiyo degree rekutsiva cellulose ether. Uye zvakare, munyu uye kusachena kunogona kuitawo kushinha kweGel. Kana tembiricha yemhinduro ichisimuka, iyo cellulose polymer zvishoma nezvishoma inorasikirwa nemvura, uye iyo visikopa yemhinduro inoderera. Pfuma yeGel isati yasvika, polymer yakadzvanywa chose uye inoumba gel. Naizvozvo, mune zvigadzirwa zvekisimendi, tembiricha inowanzo kudzorwa pazasi pekutanga tembiricha. Pasi pemamiriro ezvinhu aya, iyo yakadzika tembiricha, yakakwira viscosity, uye zvakanyatsojeka mhedzisiro yekuchengetwa uye nekuchengetwa kwemvura.
