kuoma nekukurumidza
Izvi zvinonyanya kukonzerwa nekuwedzerwa kwakanyanya kweupfu hwecalcium yedota (huwandu hweupfu hwecalcium yedota hunoshandiswa mufomura yeputty hunogona kuderedzwa zvakakodzera) hune chekuita nehuwandu hwekuchengetedza mvura hwehydroxypropyl methylcellulose, uye hune chekuitawo nekuoma kwemadziro.
Kukwesha nekumonera
Izvi zvine chekuita nehuwandu hwakawanda hwecalcium yemadota kana huwandu hushoma hwehydroxypropyl methylcellulose inochengetwa nemvura, iyo inowanzoitikawo kana viscosity yecellulose yakaderera kana huwandu hwekuwedzera huri hushoma.
Kubvisa hupfu hweputty yemukati memadziro
Izvi zvine chekuita nehuwandu hweupfu hwecalcium inowedzerwa muash (huwandu hweupfu hwecalcium inoiswa muash mufomura yeputty hudiki zvakanyanya kana kuchena kweupfu hwecalcium inoiswa muash kwakaderera zvakanyanya, uye huwandu hweupfu hwecalcium inoiswa mufomura yeputty inofanira kuwedzerwa zvakakodzera), uye zvine chekuitawo nekuwedzerwa kwecellulose. Pane hukama huripo pakati pehuwandu nehunhu, hunoonekwa muhuwandu hwekuchengetedza mvura yechigadzirwa. Mwero wekuchengetedza mvura wakaderera, uye nguva yekuita kweupfu hwecalcium inoiswa muash (calcium oxide inoiswa muupfu hwecalcium inoiswa muash haina kushandurwa zvizere kuita calcium hydroxide) haina kukwana, izvo zvinokonzerwa.
kupupuma
Izvi zvine chekuita nehunyoro hwakaoma uye kuti madziro akatsetseka, uye zvine chekuitawo nekuvakwa kwacho.
poindi yepini
Izvi zvine chekuita ne cellulose, iyo ine hunhu husina kunaka hwekuumba firimu. Panguva imwe chete, tsvina iri mu cellulose inobatana zvishoma ne ash calcium. Kana reaction yacho yakanyanya, putty powder ichaonekwa iri mumamiriro ezvinhu e bean curd residue. Haigone kuiswa pamadziro, uye haina simba rekubatana panguva imwe chete. Pamusoro pezvo, mamiriro ezvinhu aya anoitikawo nezvigadzirwa zvakaita se carboxymethyl yakasanganiswa ne cellulose.
Makomo anoputika negomba rinoputika zvinoonekwa
Zviri pachena kuti izvi zvine chekuita nekumanikidzwa kwemvura pamusoro pemvura ye hydroxypropyl methylcellulose aqueous solution. Kumanikidzwa kwemvura patafura ye hydroxyethyl aqueous solution hakusi pachena. Zvingave zvakanaka kuita mushonga wekupedzisa. Zvinoenderanawo nekuwedzera kwakanyanya kwe hydroxypropyl methylcellulose.
Kana putty yaoma, zviri nyore kutsemuka uye kuita yero
Izvi zvine chekuita nekuwedzerwa kwehuwandu hwakawanda hweupfu hweash-calcium. Kana huwandu hweupfu hweash-calcium hukawedzerwa zvakanyanya, kuomarara kweupfu hweputty kuchawedzera mushure mekuoma. Kana upfu hweputty husina kuchinjika, hunotsemuka nyore nyore, kunyanya kana huchishandiswa nesimba rekunze. Izvi zvine chekuitawo nehuwandu hwakawanda hwecalcium oxide muupfu hweash calcium.
Sei hupfu hweputty huchipera simba mushure mekuwedzera mvura?
Cellulose inoshandiswa sechinhu chinosimbisa uye chinochengetedza mvura paputty. Nekuda kwethixotropy yecellulose pachayo, kuwedzerwa kwecellulose muputty powder kunotungamirawo kuthixotropy mushure mekuwedzera mvura muputty. Iyi thixotropy inokonzerwa nekuparadzwa kwechimiro chezvikamu zviri muputty powder chisina kugadzikana. Chimiro ichi chinomuka pakuzorora uye chinoputsika kana chamanikidzwa. Kureva kuti, viscosity inoderera kana yakurungwa, uye viscosity inodzoka kana yamira.
Chii chinoita kuti putty iwedzere kurema pakukwenya?
Muchiitiko ichi, viscosity ye cellulose inowanzo shandiswa yakanyanya. Vamwe vagadziri vanoshandisa 200,000 cellulose kugadzira putty. Putty inogadzirwa nenzira iyi ine viscosity yakakura, saka inorema kana ichikweshwa. Huwandu hunokurudzirwa hweputty yemadziro emukati i3-5 kg, uye viscosity i80,000-100,000.
Sei kusimba kwe cellulose kuchinzwika zvakasiyana kana uchishandisa kusimba kwakafanana kwe cellulose munguva yechando neyezhizha?
Nekuda kwekupisa kwechinhu ichi, kupenya kweputty nemortar kunodzikira zvishoma nezvishoma nekuwedzera kwekupisa. Kana tembiricha ikapfuura tembiricha yegel yechigadzirwa, chigadzirwa chinobviswa mumvura uye chinorasikirwa nekupenya kwacho. Tembiricha yemukamuri muzhizha inowanzova pamusoro pe30 degrees, izvo zvakasiyana zvikuru netembiricha yemuchando, saka kupenya kwacho kunenge kwakaderera. Zvinokurudzirwa kusarudza chigadzirwa chine kupenya kwakakwira paunenge uchiisa chigadzirwa muzhizha, kana kuwedzera huwandu hwecellulose, uye kusarudza chigadzirwa chine tembiricha yakakwira yegel.
