Matambudziko akajairika emvura-inodzivirira putty kumadziro emukati

1. Matambudziko akajairika muputty powder:

1.1 Inooma nekukurumidza. Izvi zvinonyanya kuenderana nekuwedzera kweash calcium uye chiyero chekuchengetedza mvura yefiber, uye zvakare yakabatana nekuoma kwemadziro.

1.2 Kupepeta nekukunguruka. Izvi zvakabatana nehuwandu hwekuchengetedza mvura, izvo zviri nyore kuitika kana viscosity ye cellulose yakaderera kana kuwanda kwekuwedzera kuduku.

1.3 De-upfu. Izvi zvine hukama nehuwandu hweash calcium yakawedzerwa, uye zvakare inoenderana nehuwandu uye kunaka kwe cellulose yakawedzerwa. Inoratidzwa muhuwandu hwekuchengetedza mvura kwechigadzirwa. Nhamba yekuchengetedza mvura yakaderera uye nguva ye hydration yeash calcium haina kukwana.

1.4 Blisting. Izvi zvine hukama nehunyoro hwakaoma uye flatness yemadziro, uye zvakare inoenderana nekuvakwa.

1.5 Pini inobuda. Izvi zvakabatana ne cellulose, iyo ine urombo hwekugadzira firimu. Panguva imwecheteyo, kusvibiswa mu cellulose kunobata zvishoma neash calcium. Kana maitiro acho akaoma, iyo putty powder ichaonekwa mumamiriro ebhinzi curd yakasara. Haikwanise kuiswa pamadziro, uye haina simba rakabatana panguva imwe chete. Mukuwedzera, mamiriro aya anoitikawo nezvigadzirwa zvakaita semapoka e-carboxyl akawedzerwa kune cellulose.

1.6 Makomo anoputika nemapini anooneka. Izvi zviripachena zvine chekuita nekunetsana kwemvura pamusoro peiyo hydroxypropyl methylcellulose aqueous solution. Iko kushushikana kwemvura patafura yehydroxyethyl aqueous solution haisi pachena. Zvingava zvakanaka kuita finishing treatment.

1.7 Mushure mekunge putty yaoma, zviri nyore kuputika uye kushanduka yero. Izvi zvinoenderana nekuwedzerwa kwehuwandu hwakawanda hwegrey calcium. Kana chiyero che grey calcium chichiwedzerwa zvakanyanya, kuoma kweputty powder kuchawedzera mushure mekuoma. Kuoma chete uye pasina kuchinjika kuchatsemuka nyore, kunyanya kana ichiiswa pasi pesimba rekunze. Izvo zvakare zvine hukama neiyo yakakwirira ye calcium oxide mu grey calcium, iyo yakaunzwa kare.

2. Sei putty powder inova mutete mushure mekuwedzera mvura?

Cellulose inoshandiswa seyakakora uye inochengetedza mvura mumiriri. Pamusana pe thixotropy ye cellulose pachayo, kuwedzerwa kwe cellulose mu putty powder kunotungamirirawo kuthixotropy mushure mekuwedzera mvura kune putty. Iyi thixotropy inokonzerwa nekuparadzwa kwemaitiro akasununguka akabatanidzwa ezvikamu muputty powder. Ichi chimiro chinomuka pakuzorora uye chinoputsika pasi pekunetseka. Izvi zvinoreva kuti, viscosity inoderera pasi pekukurudzira, uye viscosity inopora kana yakamira.

3. Sei iyo putty inorema mukukwesha?

Muchiitiko ichi, viscosity ye cellulose inowanzoshandiswa yakanyanyisa. Vamwe vagadziri vanoshandisa 200,000 cellulose kugadzira putty. Iyo putty inogadzirwa nenzira iyi ine viscosity yakakwirira, saka inonzwa inorema kana ichikwesha. Nhamba yakakurudzirwa yeputty yemadziro emukati ndeye 3-5 kg, uye viscosity ndeye 80,000-100,000.

4. Sei iyo putty uye dhaka yakagadzirwa ne cellulose ine viscosity yakafanana inonzwa yakasiyana muchando uye muzhizha?

Nekuda kweiyo thermal gelation yechigadzirwa, viscosity yechigadzirwa ichaderera zvishoma nezvishoma nekuwedzera kwekushisa. Kana iyo tembiricha ichipfuura tembiricha yegel yechigadzirwa, chigadzirwa chinonatswa kubva mumvura uye chinorasikirwa nemaviscosity. Tembiricha yekamuri muzhizha kazhinji iri pamusoro pe30 madhigirii, ayo akasiyana zvakanyanya nekupisa munguva yechando, saka viscosity yakaderera. Inokurudzirwa kusarudza chigadzirwa chine viscosity yakakwirira muzhizha, kana kuwedzera huwandu hweselulosi, uye sarudza chigadzirwa chine tembiricha yepamusoro yegel. Edza kusarudza chigadzirwa chine gel tembiricha pamusoro pe70 degrees. Edza kusashandisa methyl cellulose muzhizha, tembiricha yayo yegel inosvika 55 degrees, kana tembiricha yakakwira zvishoma, viscosity yayo ichakanganiswa zvakanyanya.
