Kuparara uye kupararira kweCMC zvigadzirwa

Sanganisa CMC zvakananga nemvura kuti uite pasty glue kuti ishandiswe gare gare. Paunenge uchigadzira CMC glue, tanga wawedzera imwe mvura yakachena mubhachi tangi ine inomutsa mudziyo, uye kana iyo inokuchidzira yavhurwa, zvishoma nezvishoma uye zvakaenzana saya CMC mutangi rebatching, uchikurudzira nguva dzose, kuitira kuti CMC Inyatsobatanidzwa. nemvura, CMC inogona kunyungudika zvizere.

Pakunyungudusa CMC, chikonzero nei ichifanira kusaswa zvakaenzana uye kusimudzwa nguva dzose ndeye "kudzivirira matambudziko ekubatana, agglomeration, uye kuderedza huwandu hweCMC yakanyungudika kana CMC ikasangana nemvura", uye kuwedzera chiyero chekuparara kweCMC. Nguva yekukuchidzira haina kufanana nenguva yekuti CMC iparare zvachose. Iwo mafungiro maviri. Kazhinji kutaura, nguva yekubvongodza ipfupi pane nguva yekuti CMC iparare zvachose. Nguva inodiwa kune maviri inoenderana nemamiriro chaiwo.

CMC zvigadzirwa1

Nheyo yekusarudza nguva inokurudzira ndeyekuti: kana CMC yakapararira mumvura uye pasina mazamu makuru akajeka, kubvongodza kunogona kumiswa, zvichibvumira.CMCuye mvura kupinda uye fuse pamwe chete mumwe akamira mamiriro. Iyo yekumhanyisa kumhanya inowanzova pakati pe600-1300 rpm, uye nguva yekukurudzira inowanzodzorwa panenge awa imwe.

Hwaro hwekutarisa nguva inodiwa kuti CMC iparadzwe zvachose ndeiyi inotevera:

(1) CMC nemvura zvakasungwa zvachose, uye hapana kupatsanurwa kwakasimba-mumvura pakati pezviviri;

(2) Paka yakavhenganiswa iri muchimiro chakafanana, uye pamusoro pacho yakati sandara uye yakatsetseka;

(3) Muvara wepaste yakasanganiswa iri pedyo nekusina ruvara uye pachena, uye hapana zvinhu zvegranular mune paste. Kubva panguva iyo CMC inoiswa mubatching tank uye yakasanganiswa nemvura kusvika panguva iyo CMC yanyungudika zvachose, nguva inodiwa iri pakati pegumi nemaawa makumi maviri. Kuti uite nekukurumidza uye kuchengetedza nguva, homogenizers kana colloid mill inowanzoshandiswa kukurumidza kuparadzira zvigadzirwa.
