HPMC uye putty poda

1. Ndeipi basa guru rekushandiswa kweHPMC mu putty powder? Pane here kuita kwemakemikari?

——Mhinduro: Mune putty poda, HPMC inobata mabasa matatu ekukora, kuchengetedza mvura uye kuvaka. Kukora: Cellulose inogona kukobvu kumisa uye kuchengeta yunifomu yemhinduro kumusoro nekudzika, uye kuramba kudonha. Kuchengetwa kwemvura: ita kuti putty poda iome zvishoma nezvishoma, uye batsira madota e calcium kuti aite pasi pekuita kwemvura. Kuvaka: Cellulose ine lubricating effect, iyo inogona kuita kuti putty powder ive nekuvakwa kwakanaka. HPMC haitore chikamu mune chero chemakemikari maitiro, asi inongotamba yebetsero. Kuwedzera mvura kune putty powder uye kuiisa pamadziro ndeyekuita kwemakemikari, nokuti zvinhu zvitsva zvinoumbwa. Kana iwe ukabvisa putty powder pamadziro kubva pamadziro, uchikuya muupfu, uye uishandise zvakare, haizoshandi nokuti zvinhu zvitsva (calcium carbonate) zvakagadzirwa. ) zvakare. Zvinhu zvikuru zvinoumba ash calcium powder ndezvi: musanganiswa weCa(OH)2, CaO uye zvishoma zveCaCO3, CaO H2O=Ca(OH)2 —Ca(OH)2 CO2=CaCO3↓ H2O Basa remadota calcium. mu CO2 mumvura nemhepo Pasi pemamiriro ezvinhu aya, calcium carbonate inogadzirwa, nepo HPMC inongochengetedza mvura, ichibatsira kuita zviri nani kweash calcium, uye haibatanidzi mune chero ipi zvayo pachayo.

2. Ndeipi yakawanda yeHPMC yakawedzerwa muputty powder?

——Mhinduro: Nhamba yeHPMC inoshandiswa mukushandiswa kwemaitiro inosiyana zvichienderana nemamiriro ekunze, tembiricha, kunaka kwekoni ash calcium, formula yeputty powder uye "mhando inodiwa nevatengi". Kazhinji kutaura, pakati pe4 kg ne5 kg. Semuenzaniso: yakawanda yeputty powder muBeijing ndeye 5 kg; yakawanda yeputty powder muGuizhou i5 kg muzhizha uye 4.5 kg muchando; huwandu hwe putty muYunnan hudiki, kazhinji 3 kg kusvika 4 kg, nezvimwe.

3. Chii chinonzi viscosity yakakodzera yeHPMC mune putty powder?

——Mhinduro: Kazhinji, 100,000 yuan inokwana putty powder, uye zvinodiwa zvedhaka zvakakwirira, uye 150,000 yuan inodiwa kuti ishandiswe nyore. Uyezve, iyo inonyanya kukosha basa reHPMC ndeyekuchengetedza mvura, inoteverwa nekukora. Mune putty powder, chero bedzi kuchengetwa kwemvura kwakanaka uye viscosity yakaderera (70,000-80,000), zvinogonekawo. Zvechokwadi, iyo yakakwirira viscosity, zviri nani kuchengetedza mvura. Kana iyo viscosity inopfuura 100,000, iyo viscosity inokanganisa kuchengetwa kwemvura. Hazvina zvakawanda zvakare.

4. Sei putty hupfu hufuro?

——Mhinduro: Phenomenon: mabhuru anogadzirwa panguva yekuvaka uye mushure menguva yakati rebei, pamusoro peiyo putty inoputika.

chikonzero:

1. Chigadziko chakanyanya kushata uye kasi yekupurasita inokurumidza;

2. Iyo putty layer mune imwe yekuvakwa yakanyanya kukora, yakakura kupfuura 2.0mm;

3. Hunyoro hwehuswa hwakanyanya, uye density yakakura kana kuti idiki.

4. Mushure menguva yekuvaka, kuputika uye kupupa pamusoro pepamusoro kunonyanya kukonzerwa nekusanganiswa kusina kuenzana, nepo HPMC inobata basa mukuchengetedza mvura, kuwedzera uye kuvandudza kushanda muputty powder, uye haibatanidzi mune chero maitiro.

5. Chii chikonzero chekubviswa kwehupfu yeputty powder?

——Mhinduro: Izvi zvinonyanya kuenderana nehuwandu uye mhando yegrey calcium yakawedzerwa. Iyo yakaderera calcium ye grey calcium uye iyo isina kufanira ratio yeCaO uye Ca (OH) 2 mu grey calcium inokonzera kubviswa kwehupfu. Panguva imwecheteyo, zvakare ine hukama neHPMC. Nhamba yekuchengetedza mvura yakaderera, uye nguva yeash calcium hydration haina kukwana, iyo ichaitawo kubviswa kwehupfu.

6. Sei putty inorema mukukwesha?

——Mhinduro: Muchiitiko ichi, viscosity ye cellulose inowanzoshandiswa yakakwira zvakanyanya. Vamwe vagadziri vanoshandisa 200,000 cellulose kugadzira putty. Iyo putty inogadzirwa nenzira iyi ine viscosity yakakwirira, saka inonzwa inorema kana ichikwesha. Nhamba yakakurudzirwa yeputty powder yemukati yemadziro ndeye 3-5 kg, uye viscosity ndeye 80,000-100,000.
