1. Sodium Carboxymethyl Cellulose
Reactive printing paste chinobva kune ether chimiro chinowanikwa kuburikidza nekemikari shanduko yeyakasikwa cellulose.Iglue inonyungudika nemvura inogona kunyungudutswa mumvura inotonhora nemvura inopisa.Mhinduro yaro ine aqueous ine mabasa ekubatanidza, kukora, kuparadzira, kumisa uye kudzikamisa.
Reactive printing paste chigadzirwa che sodium carboxymethyl cellulose ine yakakwirira dhigirii etherification.Iyo yakakosha maitiro inoita kuti boka rayo rekutanga rehydroxyl ritsiviwa zvachose, kuitira kudzivirira kuita nedhayi dzinoshanda.
Sezvo iyo thickener yekudhinda paste, reactive kudhinda paste inogona kudzikamisa viscosity, kuvandudza fluidity yenamira, kuwedzera hydrophilic kugona kwedhayi, kugadzira yunifomu yekudhaya uye kuderedza mutsauko wemavara;panguva imwecheteyo, mukugezesa mushure mekudhinda uye kudhaya, chiyero chekugeza chakakwirira, Mucheka unonzwa wakapfava pakubata.
2. Kuenzanisa kwemaitiro e-reactive printing paste uye sodium alginate
2.1 Paste rate
Kuenzaniswa nesodium alginate, reactive printing paste ine viscosity yakakwirira, ingave inoshandiswa yoga kana kusanganiswa nemamwe thickeners, inogona kubudirira kuderedza mutengo wepaste;kazhinji, iyo inoshanda yekudhinda paste Muyero unongova 60-65% ye sodium alginate.
2.2 Kubuda kwemavara uye kunzwa
Iyo yemavara goho redhinda paste rakagadzirwa ne reactive printing paste se thickener yakaenzana neiyo sodium alginate, uye jira rinonzwa rakapfava mushure mekuda, iro rakaenzana neiyo sodium alginate paste zvigadzirwa.
2.3 Namira kugadzikana
Sodium alginate ndeye yakasikwa colloid, iyo isina kushivirira kwakashata kune tupukanana, pfupi yekuchengetedza nguva yemavara paste, uye iri nyore kukanganisa.Kugadzikana kwezvakajairwa sodium carboxymethyl cellulose zvigadzirwa zvakakwirira zvakanyanya kune izvo zvesodium alginate.Reactive kudhinda paste zvigadzirwa zvakagadziridzwa neakakosha maitiro, uye yavo ye electrolyte kuramba iri nani pane yakajairwa sodium carboxymethyl cellulose zvigadzirwa.Panguva imwecheteyo, vane kuwirirana kwakanaka nemakemikari anobatsira uye dhayi, uye hazvisi nyore kusvibiswa uye kuparara panguva yekuchengetedza.Kugadzikana kwemakemikari kuri nani kupfuura sodium alginate.
2.4 Rheology (inopindirana)
Zvose sodium alginate uye CMC ipseudoplastic fluid, asi sodium alginate ine yakaderera structural viscosity uye yakakwirira PVI kukosha, saka haikodzeri kutenderera (flat) kudhindwa kwekrini, kunyanya kudhinda kwepamusoro-mesh skrini;reactive printing paste products ane high structural viscosity, PVI value inenge 0.5, zviri nyore kudhinda mapatani akajeka nemitsetse.Iko kusanganiswa kwesodium alginate uye inoshingaira kudhinda paste inogona kusangana nezvimwe rheological zvinodiwa zvekudhinda paste
