1 Matambudziko akajairika mumadziro putty poda:
(1) Inooma nokukurumidza.
Izvi zvinonyanya nekuti huwandu hweash calcium powder yakawedzerwa (yakakura kwazvo, iyo yakawanda yeash calcium powder inoshandiswa muputty formula inogona kuderedzwa zvakakodzera) inobatana nehuwandu hwekuchengetedza mvura ye fiber, uye inobatanidzawo nekuoma. yemadziro.
(2) Pera woumburudza.
Izvi zvakabatana nehuwandu hwekuchengetedza mvura, izvo zviri nyore kuitika kana viscosity ye cellulose yakaderera kana kuwanda kwekuwedzera kuduku.
(3) De-upfu hwemukati wemadziro putty poda.
Izvi zvinoenderana nehuwandu hweash calcium powder yakawedzerwa (huwandu hweash calcium powder muputty formula iduku zvikuru kana kuchena kweash calcium powder yakanyanya kuderera, uye uwandu hwehupfu hwekasium muputty powder formula inofanira. kuwedzerwa zvakakodzera), uye zvakare ine chekuita nekuwedzera kwe cellulose. Pane hukama pakati pehuwandu uye hutano, hunoratidzwa muhuwandu hwekuchengetedza mvura kwechigadzirwa. Mvura yekuchengetedza mvura yakaderera, uye ash calcium powder (iyo calcium oxide mu ash calcium powder haina kuchinjwa zvakakwana ku calcium hydroxide ye hydration) nguva haina kukwana, iyo inokonzerwa.
(4) Blessing.
Izvi zvine hukama nehunyoro hwakaoma uye flatness yemadziro, uye zvakare inoenderana nekuvakwa.
(5) Mapoinzi anooneka.
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.
(6) Makomba nemapini anobuda.
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.
(7) Mushure mekunge putty yaoma, zviri nyore kutsemuka uye kuita yero.
Izvi zvakabatana nekuwedzera kwehuwandu hweash-calcium powder. Kana iyo yakawanda ye-ash-calcium powder inowedzera zvakanyanya, kuoma kweputty powder kuchawedzera mushure mekuoma. Kana iyo putty powder isina kushanduka, inoputika nyore nyore, kunyanya kana ichiiswa pasi pesimba rekunze. Iyo inobatanawo nehuwandu hwehuwandu hwe calcium oxide mu ash calcium powder, iyo yakatangwa kare.
2 Sei hupfu hunoita hutete mushure mekuwedzera mvura?
Cellulose inoshandiswa seyakakura 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 ichirema zvakanyanya 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 zvakasiyana muchando uye chirimo?
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. Zvinokurudzirwa kusarudza chigadzirwa chine viscosity yakakwirira paunoshandisa chigadzirwa muzhizha, kana kuwedzera huwandu hweselulosi, uye kusarudza chigadzirwa chine tembiricha yepamusoro yegel. Edza kusashandisa methyl cellulose muzhizha, tembiricha yayo yegel inosvika 55 degrees, kana tembiricha yakakwira zvishoma, viscosity yayo ichakanganiswa zvakanyanya.
