(1) Hydroxypropyl methylcellulose (HPMC) yakakamurwa kuita yakajairwa mhando (inopisa-inonyungudika mhando) uye mvura inotonhora mhando:
Chimiro chemhando, clumps mumvura inotonhora, asi inogona kukurumidza kupararira mumvura inopisa uye inonyangarika mumvura inopisa. Kana tembiricha yadzikira kune imwe tembiricha, viscosity inozoonekwa zvishoma nezvishoma kusvika yaita yakajeka viscous colloid. Chikonzero chekusangana nemakumbo emvura inotonhora ndechekuti: iyo yekunze cellulose poda inosangana nemvura inotonhora, pakarepo inova viscous, inokora kuita yakajeka colloid, uye cellulose mukati yakakomberedzwa necolloid isati yasangana nemvura, uye ichiri muupfu. form. , asi inonyungudika zvishoma nezvishoma. Zvigadzirwa zvakajairika hazvidi kushandisa mvura inopisa mumashandisirwo anoshanda, nekuti putty poda kana dhaka ipfu yakasimba. Mushure mekusanganiswa kwakaoma, cellulose inoparadzaniswa nezvimwe zvinhu. Kana ikasangana nemvura, inobva yaita viscous uye haizogadziri boka.
Chigadzirwa chekukurumidza chinopararira nekukurumidza kana chikasangana nemvura inotonhora uye chinonyangarika mumvura. Panguva ino, mvura haina viscosity, nokuti HPMC inongopararira mumvura pasina kuparara kwechokwadi. Kubva anenge maminetsi maviri, viscosity yemvura inowedzera zvishoma nezvishoma, ichigadzira yakajeka viscous colloid.
(2) Chiyero chekushandiswa kwemhando yakajairwa uye yekukurumidza mhando: yekukurumidza mhando inonyanya kushandiswa mune yemvura glue, zvizorwa, uye yekuwachira. Nekuda kwekuti iyo instant cellulose yakabatwa ne dialdehyde, kuchengetwa kwemvura uye kugadzikana hakuna kunaka sezvigadzirwa zvakajairika. Naizvozvo, muhupfu hwakaoma senge putty poda uye dhaka, tinokurudzira zvigadzirwa zvakajairika.
Maitiro ekusarudza iyo chaiyo viscosity ye cellulose:
1. Chokutanga pane zvose, tinofanira kunzwisisa basa re cellulose ether: kuchengetedza mvura uye kuwedzera.
2. Iyo indasitiri inogona kazhinji kutaura 100,000 viscosity, 150,000 viscosity, uye 200,000 viscosity. Zviyero izvi zvinorevei? Chii chinokanganisa mayuniti akasiyana ekuyera pachigadzirwa?
(1) Yekuchengetedza mvura
Kuita kwekuchengetedza mvura kunowedzera nekuwedzera kwe viscosity, asi maererano nemamiriro ezvinhu emusika, apo viscosity ye cellulose inodarika 100,000, kushanda kwekuchengetedza mvura kunowedzera ne viscosity.
(2) Zvekukora
Kazhinji kutaura, kana izvo zvinobudirira zvemukati zvakajairika, iyo yakakura iyo unit, ndizvo zviri nani kukora kuita. Izvi zvinoreva, high viscosity inoda mvura yakawanda, uye chiyero chekuchengetedza mvura hachichinje zvakanyanya.
3. Makambani akawanda anoshandisa zviyero zvakasiyana-siyana, kureva, dhaka dzakasiyana uye cellulose ether zvinyorwa zvakasiyana, asi kune mafekitari maduku, zvichawedzera mari. Mafekitari madiki mazhinji anongoshandisa imwe fiber plastiki ether kuti ishandiswe zvakajairika, kureva kuti, kuyerwa kwakasiyana. ! Kazhinji, 100,000 mauniti ndiwo anonyanya kushandiswa.
4. Kazhinji 200,000 viscosity inoshandiswa kugadzira dhaka rekubatanidza, uye 100,000 inoshandiswawo kuzvigadzirisa, 100,000 yekuzvigadzirisa, uye 80,000 yekupurasita. Zvechokwadi, inonyanya kugadziriswa nehutano hwekuchengetedza mvura. Isu hatikurudzire vatengi kushandisa yakakwira viscosity. Semuenzaniso, kune 200,000 units, iyo yakakwirira viscosity ye cellulose ether, iyo inonyanya kugadzikana, uye kune zvakawanda zvigadzirwa zvenhema. Vamwe vatengi vanoshuma kuti 20W chaiyo chigadzirwa chakanyanya kunamira uye kuvakwa hakuna kunyatso kunaka.
5. Kuchengetwa kwemvura ye cellulose ether inoshandiswa mudhaka yakasiyana nekuchengetwa kwemvura ye cellulose ether mukuedza. Kunyangwe kana kuchengetwa kwemvura kwe cellulose ether pachayo kwakanaka, hazvireve kuti mhedzisiro mudhaka ndeyechokwadi Zvakanaka, inonyanya kutsanangurwa nekuita kwezvakasara zvekuwedzera mune formula, kuwanda kwekuwedzera, uye kusanganisa mhedzisiro ye iyo yakaoma poda dhaka midziyo. Zvakanakisa kuishandisa pamadziro kuti uone mhedzisiro. Ichi ndicho chokwadi!
