1. Matambudziko anowanzoitika muupfu hweputty
Inooma nekukurumidza:
Chikonzero chikuru ndechekuti huwandu hweupfu hwecalcium inowedzerwa mudota (hwakanyanya kukura, huwandu hweupfu hwecalcium inoiswa mufomura yeputty hunogona kuderedzwa zvakakodzera) hunoenderana nehuwandu hwemvura inochengetwa mufayibha, uye hune chekuitawo nekuoma kwemadziro.
Kubvisa nekumonera:
Zvinoenderana nehuwandu hwemvura inochengetwa, uye kusimba kushoma kweselulosi kunowanzo sangana nemamiriro ezvinhu aya kana huwandu hwekuwedzera hushoma.
Kubvisa hupfu hweputty yemukati memadziro:
Huwandu hweupfu hwecalcium inowedzerwa muash (huwandu hweupfu hwecalcium inoiswa muash mufomura yeputty hudiki zvakanyanya kana kuchena kweupfu hwecalcium inoiswa muash hushoma zvakanyanya, uye huwandu hwecalcium inoiswa muash mufomura yeputty inoiswa muash hunofanira kuwedzerwa zvakakodzera), uye hunoenderanawo nehuwandu hwecellulose uye Hunhu hwacho hunoenderana, izvo zvinoratidzwa muhuwandu hwekuchengetedza mvura yechigadzirwa. Huwandu hwekuchengetedza mvura hushoma, uye upfu hwecalcium inoiswa muash (calcium oxide inoiswa muash calcium inoiswa muash haina kushandurwa zvizere kuita calcium hydroxide yekuchenesa) haisi nguva yakakwana, izvo zvinokonzerwa.
Kuburitsa furo:
Hunyoro hwakaoma hwemadziro hunoenderana nekuti madziro acho akati sandara, uye hunoenderanawo nekuvakwa kwawo.
Chinhu chinoonekwa:
Yakabatana ne cellulose, hunhu hwayo hwekuumba firimu hwakaderera, uye panguva imwe chete, kusvibiswa kuri mu cellulose kunosangana zvishoma ne ash calcium. Kana mhinduro yacho yakanyanya, putty powder ichaonekwa iri mumamiriro ezvinhu e bean curd residue. Haigone kuiswa pamadziro, uye haina simba rakabatana panguva imwe chete. Pamusoro pezvo, mamiriro ezvinhu aya anoitikawo nezvigadzirwa zvakaita se carboxymethyl yakasanganiswa ne cellulose.
Kana putty yaoma, zviri nyore kutsemuka uye kuita yero:
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, huchava nyore kutsemuka, kunyanya kana huchishandiswa nesimba rekunze. Zvine chekuitawo nehuwandu hwakawanda hwecalcium oxide muupfu hweash calcium.
2. Sei hupfu hweputty huchipera simba mushure mekuwedzera mvura?
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 che putty powder chisina kubatana. Chimiro ichi chinomuka pakuzorora uye chinoputsika kana chave kumanikidzwa. Kureva kuti, viscosity inoderera kana yakurungwa, uye viscosity inodzoka kana yakamira.
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 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 kuti muzhizha, edza kusarudza chigadzirwa chine kupenya kwakakwira paunenge uchiisa chigadzirwa ichi, kana kuwedzera huwandu hwecellulose.
