1. Putty powder inooma nokukurumidza
Mhinduro: Izvi zvinonyanya kuenderana nekuwedzera kweash calcium uye chiyero chekuchengetedza mvura yefiber, uyewo zvine chokuita nekuoma kwemadziro.
2. Iyo putty hupfu inosvuura uye inokunguruka
Mhinduro: Izvi zvakabatana nehuwandu hwekuchengetedza mvura, izvo zviri nyore kuitika kana viscosity ye cellulose yakaderera kana kuwanda kwekuwedzera kuduku.
3. Putty poda de-upfu
Mhinduro: Izvi zvinoenderana nehuwandu hwemadota e calcium yakawedzerwa, uye inobatanidzawo nehuwandu uye hutano hwe cellulose yakawedzerwa.Inoratidzwa muhuwandu hwekuchengetedza mvura kwechigadzirwa.Nhamba yekuchengetedza mvura yakaderera uye nguva ye hydration yeash calcium haina kukwana.
4. Putty powder ichipupa
Mhinduro: Izvi zvine hukama nehunyoro hwakaoma uye flatness yemadziro, uye zvakare inoenderana nekuvakwa.
5. Pinpoints inoonekwa muputty powder
Mhinduro: Izvi zvakabatana ne cellulose, iyo ine urombo husina kunaka hwekugadzira firimu, uye zvakare kusvibiswa mu cellulose kunobata zvishoma neash calcium.Kana mhinduro yacho yakanyanyisa, iyo putty powder inenge iri mumamiriro ekusara kwebhinzi curd.Haikwanise kuiswa pamadziro, uye haina simba rakabatana panguva imwe chete.Mukuwedzera, mamiriro aya anoitikawo nezvigadzirwa zvakaita semapoka e-carboxyl akawedzerwa kune cellulose.
6. Mapako ane kuputika kwemakomo uye maburi anooneka
Mhinduro: Izvi zviri pachena zvine hukama nekukakavadzana 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 kuputika uye kushanduka yero
Mhinduro: Izvi zvinoenderana nekuwedzerwa kwehuwandu hwegrey calcium.Kana chiyero che grey calcium chichiwedzerwa zvakanyanya, kuoma kweputty powder kuchawedzera mushure mekuoma.Chete kuoma uye hapana kuchinjika kuchatsemuka nyore, kunyanya kana ichiiswa pasi pesimba rekunze.Izvo zvakare zvine hukama neiyo yakakwirira ye calcium oxide mu grey calcium, iyo yakaunzwa kare.
8. Sei putty powder ichiva mutete mushure mekuwedzera mvura?
Mhinduro: Cellulose inoshandiswa seyakakora uye inochengetedza mvura pane putty.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.Kureva kuti, viscosity inoderera pasi pekukurudzira, uye viscosity inopora kana yakamira.
9. Sei putty inorema mukukwesha?
Mhinduro: 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 powder yemukati yemadziro ndeye 3-5 kg, uye viscosity ndeye 80,000-100,000.
10. Sei iyo putty uye dhaka yakagadzirwa ne cellulose ine viscosity yakafanana inonzwa zvakasiyana munguva yechando nezhizha?
Mhinduro: 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 yepamusoro paunenge uchiisa chigadzirwa muzhizha, kana kuwedzera huwandu hweselulosi, uye sarudza chigadzirwa chine tembiricha yepamusoro yegel, edza kushandisa zvigadzirwa zvegiredhi reMK, tembiricha yegel yechigadzirwa ichi ivhareji. Pamusoro pe70 degrees.Edza kusashandisa methyl cellulose muzhizha, tembiricha yayo yegel inotenderedza 55 degrees.
