1. Matambudziko anowanzo mu putty powder
Inoomesa nekukurumidza:
Chikonzero chikuru ndechekuti kuwanda kweash 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.
Peeling uye rolling:
Iyo yakabatana nehuwandu hwekuchengetedza mvura, uye yakaderera viscosity ye cellulose inotarisana nemamiriro ezvinhu aya kana kuwanda kwekuwedzera kudiki.
De-upfu hwemukati wemadziro putty poda:
Kuwanda kweash calcium powder yakawedzerwa (huwandu hweash calcium powder muputty formula yakanyanya kuduku kana kuchena kweash calcium powder yakanyanya kuderera, uye chiyero cheash calcium powder mu putty powder formula inofanira kuwedzerwa zvakakodzera) , uye inobatanidzawo nehuwandu hweselulosi uye Unhu hunobatana, 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) haisi nguva yakakwana, iyo inokonzerwa.
Furo:
Iyo yakaoma humidity yemadziro ine hukama ne flatness, uye inobatanawo nekuvakwa.
Chiratidzo chinowanikwa:
Iyo yakabatana ne cellulose, pfuma yayo yekugadzira firimu haina kunaka, uye 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 ezvinhu aya anoitikawo nemishonga yakadai se carboxymethyl yakasanganiswa ne cellulose.
Mushure mekunge putty yaoma, zviri nyore kutsemuka uye kushanduka yero:
Iyo yakabatana 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, ichava nyore kuputika, kunyanya kana ichiiswa pasi pesimba rekunze. Iyo inobatanawo nehuwandu hwehuwandu hwe calcium oxide mu ash calcium powder.
2. Sei putty powder ichiva mutete mushure mekuwedzera mvura?
Cellulose inoshandiswa seyakakora uye inochengetedza mvura mumiriri pa putty. Pamusana pe thixotropy ye cellulose pachayo, kuwedzerwa kwe cellulose mu putty powder kunotungamirirawo kuthixotropy mushure mekuwedzera mvura kune putty. Iyi thixotropy inokonzerwa nekuparadzwa kweiyo yakasununguka yakasungwa chimiro cheputty powder. Ichi chimiro chinomuka pakuzorora uye chinoputsika pasi pekunetseka. Izvi zvinoreva kuti, viscosity inoderera pasi pekukurudzira, uye viscosity inopora kana yakamira.
3. Ndechipi chikonzero nei putty iri kuremerwa 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 yakafanana viscosity cellulose inonzwa yakasiyana munguva yechando nezhizha?
Nekuda kweiyo thermal gelation yechigadzirwa, viscosity ye putty uye dhaka 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 kuti muzhizha, edza kusarudza chigadzirwa chine viscosity yakakwirira paunoshandisa chigadzirwa, kana kuwedzera huwandu hweselulosi.
