1. Matambudziko anowanzoitika muupfu hweputty
Kuomesa nekukurumidza: Izvi zvinonyanya kukonzerwa nehuwandu hweupfu hwecalcium ye lime hunowedzerwa (hwakanyanya kukura, huwandu hwecalcium ye lime inoshandiswa mu putty formula hunogona kuderedzwa zvakakodzera) hunoenderana nehuwandu hwemvura inochengetwa mu fiber, uye hunewo hukama nekuoma kwemadziro.
Bvisa wobva wamonera. Izvi zvine chekuita nekuchengetwa kwemvura, izvo zviri nyore kuitika kana cellulose iri shoma kana kuti huwandu hwekuwedzera huri hushoma.
Kubvisa hupfu hweputty yemadziro emukati: Izvi zvine chekuita nehuwandu hwecalcium powder inowedzerwa muash (huwandu hwecalcium powder yeash muputty formula hudiki zvakanyanya kana kuchena kwecalcium powder yeash kwakaderera zvakanyanya, uye huwandu hwecalcium powder yeash muputty powder fomura hunofanira kuwedzerwa zvakakodzera) Panguva imwe chete, zvine chekuitawo nehuwandu uye mhando yecellulose, iyo inoratidzwa muhuwandu hwekuchengetedza mvura yechigadzirwa. Mwero wekuchengetedza mvura wakaderera, uye nguva yeash calcium powder (calcium oxide muash calcium powder haina kushandurwa zvizere kuita calcium hydroxide) haina kukwana. ,yakakonzerwa.
Kuputika: Izvi zvine chekuita nehunyoro hwakaoma uye kuti madziro akatsetseka, uye zvine chekuitawo nekuvakwa kwacho.
Mapoinzi anoonekwa. 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 mhinduro 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.
Kuonekwa kwemaburi nemaburi: Izvi zvine chekuita nekumanikidzwa kwemvura pamusoro pemvura yehydroxypropyl methylcellulose aqueous solution. Kumanikidzwa kwemvura yehydroxyethyl aqueous solution hakusi pachena. Zvingave zvakanaka kuita mushonga wekupedzisa.
Kana putty yaoma, zviri nyore kutsemuka nekutsvuka: izvi zvine chekuita nekuwedzerwa kwehuwandu hwakawanda hweupfu hwecalcium yedota. Kana huwandu hweupfu hwecalcium yedota hwakawandisa, kuomarara kweupfu hweputty kunowedzera mushure mekuoma. Kuomarara chete kusina kuchinjika ndiko kunotsemuka zviri nyore, kunyanya Zviri nyore kutsemuka kana zvashandiswa nesimba rekunze. Zvinoenderanawo nehuwandu hwakawanda hwecalcium oxide muupfu hwecalcium yedota.
2. Sei hupfu hweputty huchipera simba mushure mekuwedzera mvura?
Cellulose inoshandiswa sechinhu chinosimbisa uye chinochengetedza mvura muputty. 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.
3. Chii chinoita kuti putty ireme zvakanyanya pakukwesha?
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.
4. Sei viscosity cellulose yakafanana ichinzwa yakasiyana munguva yechando neyezhizha?
Nekuda kwekupisa kwemuchina, 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. Edza kusashandisa methyl cellulose muzhizha. Tembiricha yegel iri pakati peAnenge madhigirii makumi mashanu nemashanu, tembiricha yakakwira zvishoma, uye kupenya kwayo kuchakanganiswa zvakanyanya.
