Basa rehydroxypropyl methylcellulose mu putty
Kubva pakukora, kuchengetedza mvura nekuvakwa kwemabasa matatu.
Kukora: Cellulose inogona kukwizwa kuti imise, chengeta mhinduro yunifomu uye isingachinji, uye kuramba kudonha. Kuchengetwa kwemvura: Ita kuti putty powder iome zvishoma nezvishoma, uye ubatsire kuita kweash calcium pasi pekuita kwemvura. Kuvaka: Cellulose ine lubricating effect, iyo inogona kuita kuti putty powder ive nekushanda kwakanaka. Hydroxypropyl methylcellulose haitore chikamu mune chero makemikari anoita uye inongotora basa rekubatsira. Putty powder inowedzerwa nemvura kuti igadzire rusvingo, iyo ikemikari inogadzirisa, nokuti pane kuumbwa kwechinhu chitsva calcium carbonate. Izvo zvikamu zvikuru zveash calcium powder ndezvi: musanganiswa we calcium hydroxide Ca (OH) 2, calcium oxide CaO uye shoma shoma ye calcium carbonate CaCO3. Ash calcium inoumba calcium carbonate pasi pekuita kwe CO2 mumvura nemhepo, nepo hydroxypropyl methyl Cellulose inongochengeta mvura uye inobatsira kuita zviri nani kweash calcium, iyo pachayo isingabatanidzi mune chero maitiro.
Isu tinotanga kuongorora zvikonzero zvekudonha kwehupfu hweputty kubva kune zvakasvibirira zve putty: ash calcium powder, hydroxypropyl methylcellulose, heavy calcium powder, water ash calcium powder.
1. Mukugadzirwa chaiko, kuitira kukurumidza kuparara, tembiricha yecalcination inowanzowedzera kusvika 1000-1100 °C. Nekuda kwehukuru hukuru hwemaraimestone mbishi kana kugovanisa tembiricha isina kuenzana muchoto panguva yekuverengera, lime inowanzo ine underfired lime uye overfired lime. Iyo calcium carbonate mu-underfire lime haina kuparara zvachose, uye haina simba rakabatana panguva yekushandiswa, iyo isingagoni kupa simba rakakwana rakabatana kune putty, zvichiita kuti kubviswa kwehupfu kunokonzerwa nekusakwana kwekuoma uye simba reputty.
2. Iyo yakakwirira ye calcium hydroxide mu ash calcium powder, zviri nani kuoma kweputty yakagadzirwa. Pane zvinopesana, iyo yakaderera yehuwandu hwe calcium hydroxide mu ash calcium powder, yakaipisisa kuoma kweputty panzvimbo yekugadzira, zvichiita kuti dambudziko rekubvisa upfu uye kubviswa kwehupfu.
3. Iyo ash calcium powder inosanganiswa nehuwandu hwehuwandu hwehupfu hwehupfu, hunoita kuti zvinyorwa zveash calcium powder zvive zvakaderera kuti zvipe kuoma kwakakwana uye simba kune putty, zvichiita kuti putty idonhe poda. Basa guru reputty powder ndeyekuchengeta mvura, kupa mvura yakakwana yekuomeswa kweash calcium poda, uye kuve nechokwadi chekuomesera kwakakwana. Kana pane dambudziko nehutano hwe hydroxypropyl methylcellulose kana kuti zvinyorwa zvinobudirira zvakaderera, unyoro hwakakwana hahugoni kupiwa, izvo zvichaita kuti kuomerwa kuve kusina kukwana uye kunokonzera putty kudonha poda.
Inogona kuwanikwa kubva pamusoro apa kuti hutano hwe hydroxypropyl methylcellulose hwakashata zvikuru uye haugoni kuwana chimwe chiitiko, uye putty powder ichawa. Chikonzero chikuru igrey beggar heavy calcium.
