Basa rehydroxypropyl methylcellulose muputty
Kubva pakukora, kuchengetedza mvura uye kuvaka mabasa matatu.
Kukora: Cellulose inogona kukobvurwa kuti irambe yakamanikana, ichengetedze mvura yakafanana uye ichishanda zvakanaka, uye inodzivirira kudonha. Kuchengetwa kwemvura: Ita kuti putty powder iome zvishoma nezvishoma, uye inobatsira ash calcium kuita zvakanaka pasi pemvura. Kugadzirwa: Cellulose ine mafuta ekuzora, izvo zvinogona kuita kuti putty powder ishande zvakanaka. Hydroxypropyl methylcellulose haibatanidzi mune chero chemical reaction uye inongobatsira chete. Putty powder inowedzerwa nemvura kuti iunganidze madziro, inova chemical reaction, nekuti pane kuumbwa kwechinhu chitsva calcium carbonate. Zvikamu zvikuru zveash calcium powder ndeizvi: musanganiswa wecalcium hydroxide Ca(OH)2, calcium oxide CaO uye calcium carbonate CaCO3 shoma. Ash calcium inogadzira calcium carbonate pasi peCO2 mumvura nemhepo, nepo hydroxypropyl methyl Cellulose inongochengeta mvura uye inobatsira ash calcium kuita zvakanaka, iyo pachayo isingabatanidzi mune chero reaction.
Kutanga tinoongorora zvikonzero zvekudonha kwehupfu hweputty kubva muzvinhu zvakagadziriswa zveputty: ash calcium powder, hydroxypropyl methylcellulose, heavy calcium powder, water ash calcium powder.
1. Mukugadzirwa chaiko, kuti kukurumidze kuora, tembiricha ye calcination inowanzo wedzerwa kusvika 1000-1100 °C. Nekuda kwehukuru hwezvinhu zve limestone kana kupararira kusina kuenzana kwekupisa muchoto panguva ye calcination, lime inowanzo kuve ne lime isina kupisa uye lime yakapfurwa zvakanyanya. Calcium carbonate iri mu lime isina kupisa haiparare zvachose, uye haina simba rakabatana panguva yekushandiswa, iyo isingakwanise kupa simba rakabatana rakakwana ku putty, zvichikonzera kubviswa kwehupfu kunokonzerwa nekusakwana kwekuoma uye simba re putty.
2. Kana huwandu hwecalcium hydroxide muupfu hwecalcium hweash hwakawedzera, kuoma kweputty kunobuda. Kusiyana neizvi, kana huwandu hwecalcium hydroxide muupfu hwecalcium hweash hwaderera, kuoma kweputty panzvimbo yekugadzira kwakawedzera, zvichikonzera dambudziko rekubvisa hupfu uye kubvisa hupfu.
3. Upfu hwecalcium yemudota hunosanganiswa nehuwandu hwakawanda hwecalcium yakawandisa, izvo zvinoita kuti huwandu hwecalcium yemudota huve hwakaderera zvakanyanya kuti huve hwakasimba uye hwakasimba zvakakwana kuputty, zvichiita kuti putty idonhe. Basa guru reputty powder nderekuchengetedza mvura, kupa mvura yakakwana yekuomesa upfu hwecalcium yemudota, uye kuona kuti inoomesa zvakakwana. Kana paine dambudziko nehunhu hwehydroxypropyl methylcellulose kana huwandu hwayo husina kunaka, hunyoro hwakakwana hahugone kuwanikwa, izvo zvichaita kuti kuoma kusakwane uye kukonzera putty kudonhedza upfu.
Kubva pane zvataurwa pamusoro apa, zvinogona kuwanikwa kuti mhando yehydroxypropyl methylcellulose haina kunaka uye haigone kuita chimwe chinhu, uye putty powder inodonha. Chikonzero chikuru igray beggar heavy calcium.
