1. Upfu hweputty hunooma nekukurumidza
Mhinduro: Izvi zvinonyanya kuenderana nekuwedzerwa kwecalcium yemadota uye mwero wekuchengetedza mvura kwefiber, uye zvakare zvine chekuita nekuoma kwemadziro.
2. Upfu hweputty hunobvisa mavanga uye hunotenderera
Mhinduro: Izvi zvine chekuita nekuchengetwa kwemvura, izvo zviri nyore kuitika kana viscosity ye cellulose yakaderera kana huwandu hwekuwedzera huri hudiki.
3. Kubvisa hupfu hweputty
Mhinduro: Izvi zvine chekuita nehuwandu hwecalcium inowedzerwa mudota, uye zvine chekuitawo nehuwandu uye mhando yecellulose inowedzerwa. Zvinoratidzwa muhuwandu hwemvura inochengetwa muchigadzirwa. Mwero wekuchengetedza mvura wakaderera uye nguva yemvura inoiswa mudota haina kukwana.
4. Putty powder inoburitsa furo
Mhinduro: Izvi zvine chekuita nehunyoro hwakaoma uye kuti madziro acho akati sandara, uye zvine chekuitawo nekuvakwa kwacho.
5. Mapoinzi anoonekwa muupfu hweputty
Mhinduro: Izvi zvine chekuita ne cellulose, iyo ine hunhu husina kunaka hwekuumba firimu, uye kusvibiswa kuri mu cellulose kunosangana zvishoma ne ash calcium. Kana reaction yacho yakanyanya, putty powder inenge iri muchimiro che bean curd residue. Haigone kuiswa pamadziro, uye haina simba rekubatana panguva imwe chete. Pamusoro pezvo, mamiriro ezvinhu aya anoitikawo nezvigadzirwa zvakaita se carboxyl groups zvakawedzerwa ku cellulose.
6. Mapako nemakomba emakomo anoputika anoonekwa
Mhinduro: 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.
7. Kana putty yaoma, zviri nyore kutsemuka uye kuita yero
Mhinduro: Izvi zvine chekuita nekuwedzerwa kwe grey calcium yakawanda. Kana huwandu hwe grey calcium hukawedzerwa zvakanyanya, kuomarara kwe putty powder kuchawedzera mushure mekuoma. Kuomarara uye kusachinjika chete ndiko kunongotsemuka zviri nyore, kunyanya kana ikashandiswa nesimba rekunze. Izvi zvine chekuitawo nehuwandu hwakawanda hwe calcium oxide mu grey calcium, iyo yakatangwa kare.
8. Sei hupfu hweputty huchipera simba mushure mekuwedzera mvura?
Mhinduro: Cellulose inoshandiswa sechinhu chinosimbisa uye chinochengetedza mvura pa putty. Nekuda kwe thixotropy ye cellulose pachayo, kuwedzerwa kwe cellulose mu putty powder kunotungamirawo ku thixotropy mushure mekuwedzera mvura mu putty. Iyi thixotropy inokonzerwa nekuparadzwa kwechimiro chezvikamu zviri mu putty powder chisina kugadzikana. Chimiro ichi chinomuka pakuzorora uye chinoputsika kana chamanikidzwa. Kureva kuti, viscosity inoderera kana yakurungwa, uye viscosity inodzoka kana yamira.
9. Sei putty ichirema pakukwenya?
Mhinduro: 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 powder yemadziro emukati i3-5 kg, uye viscosity i80,000-100,000.
10. Sei putty nemortar zvakagadzirwa ne cellulose zvine viscosity yakafanana zvichinzwa zvakasiyana munguva yechando neyezhizha?
Mhinduro: Nekuda kwekupisa kwechigadzirwa, viscosity yechigadzirwa ichadzikira zvishoma nezvishoma nekuwedzera kwekupisa. Kana tembiricha ikapfuura tembiricha yegel yechigadzirwa, chigadzirwa chichabviswa mumvura uye chicharasikirwa ne viscosity yacho. Tembiricha yemukamuri muzhizha inowanzova pamusoro pemadhigirii makumi matatu, izvo zvakasiyana zvikuru netembiricha yechando, saka viscosity yakaderera. Zvinokurudzirwa kusarudza chigadzirwa chine viscosity yakakwira paunenge uchiisa chigadzirwa muzhizha, kana kuwedzera huwandu hwecellulose, uye kusarudza chigadzirwa chine tembiricha yakakwira yegel, edza kushandisa zvigadzirwa zveMK grade, tembiricha yegel yechigadzirwa ichi ivhareji Pamusoro pemadhigirii makumi manomwe. Edza kusashandisa methyl cellulose muzhizha, tembiricha yayo yegel inenge madhigirii makumi mashanu nemashanu,
