Chokutanga pane zvose, giredhi rekuvaka glue rinofanira kufunga nezvezvinhu zvakasvibirira.Chikonzero chikuru chekuiswa kweglue yekuvaka kusapindirana pakati pe acrylic emulsion uye hydroxypropyl methylcellulose (HPMC).Chechipiri, nekuda kwekusakwana nguva yekusanganisa;kune zvakare kushomeka kwekukora kuita kwekuvaka glue.Mukuvaka glue, unofanirwa kushandisa instant hydroxypropyl cellulose (HPMC), nekuti HPMC inongopararira mumvura, haina kunyatso kunyungudika.Mushure memaminitsi maviri, viscosity yemvura yakawedzera zvishoma nezvishoma, ichigadzira yakajeka viscous colloidal solution.Zvigadzirwa zvinopisa zvinonyunguduka, kana zvikaiswa mumvura inotonhora, zvinogona kukurumidza kupararira mumvura iri kufashaira uye zvinonyangarika mumvura inopisa.Kana tembiricha yadonha kusvika kune imwe tembiricha, viscosity inoonekwa zvishoma nezvishoma kusvika yakajeka yakazara viscous colloidal mhinduro yagadzirwa.Iyo yakanyanya kukurudzirwa dosage yehydroxypropyl methylcellulose (HPMC) mukuvaka glue ndeye 2-4KG.
Hydroxypropyl methylcellulose (HPMC) ine zvimiro zvemuviri zvakadzikama muzvinonamira pakuvaka, uye ine mhedzisiro yakanaka yekubvisa mildew nekukiya mvura, uye haizokanganiswe nekuchinja kwepH kukosha.Iyo viscosity inogona kushandiswa pakati pe100,000 s uye 200,000 s.Mukugadzira, iyo yakakwirira viscosity, zviri nani.Viscosity iri inversely proportional kune bond compressive simba.Iyo yakakwirira viscosity, iyo yakaderera iyo yekumanikidza simba.Kazhinji, viscosity ye100,000 s yakakodzera.
Sanganisa CMC nemvura uye gadzira dope paste kuti ushandiswe gare gare.Paunenge uchiisa CMC paste, wedzera imwe huwandu hwemvura inotonhora kune batching tangi nemuchina unomutsa.Kana muchina wekubvongodza watanga, zvishoma nezvishoma uye zvakaenzanirana chimwaya carboxymethyl cellulose mubatching tank, uye ramba uchimutsa, kuitira kuti carboxymethyl cellulose nemvura zvinyatsobatanidzwa, uye carboxymethyl cellulose inonyungudika zvachose.Pakunyungudutsa CMC, kazhinji zvinodiwa kupararira zvakaenzana uye kusanganisa nguva dzose, kuitira kuti zvirinani "kudzivirira kukoromoka uye agglomeration yeCMC mushure mekunge yasangana nemvura, uye kuderedza dambudziko rekuparara kweCMC" uye kuwedzera chiyero chekuparara kweCMC. .
Nguva yekusanganiswa haina kufanana nenguva yekuti CMC iparare zvachose.i 2 tsananguro.Kazhinji kutaura, nguva yekusanganisa ipfupi pane iyo CMC yekunyungudika zvachose, zvinoenderana neruzivo.Hwaro hwekutonga nguva yekusanganiswa ndeyekuti kana CMC yakapararira mumvura isina mapundu akajeka, kusanganisa kunogona kumiswa, kuitira kuti CMC nemvura zvipinde mukati memumwe nemumwe pasi pemamiriro e data.Pane zvikonzero zvakati wandei zvekuona nguva inodiwa yekupedza kuparara kweCMC:
(1) CMC nemvura yakanyatsobatanidzwa, uye hapana yakasimba-yemvura yekuparadzanisa michina pakati pazvo;
(2) Iyo yakasanganiswa paste yakanyatso kuenzaniswa uye yakajairika, ine yakatsetseka uye yakatsetseka pamusoro;
(3) Mushonga wakavhenganiswa hauna ruvara uye unonyatsojeka, uye hapana zvimedu mumucheka.Zvinotora maawa gumi kusvika makumi maviri kubva panguva iyo CMC inoiswa mubatching tank uye yakasanganiswa nemvura kusvika yanyungudika zvachose.
