Nhamba yeHPMC inoshandiswa mumashandisirwo anoshanda inosiyana zvichienderana nemamiriro ekunze, tembiricha, hutano hwemunharaunda ash calcium powder, fomu yeputty powder uye "hutano hunodiwa nevatengi".Kazhinji kutaura, iri 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.
Ndeipi viscosity yakakodzera yehydroxypropyl methylcellulose (HPMC) yekugadzirwa kweputty powder?
Putty poda inowanzoita 100,000 yuan, 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.
Ndeipi basa guru rekushandiswa kweHPMC mune putty powder?
Mune putty poda, HPMC inoita 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, uikuya muupfu, uye uishandise zvakare, haigoni kushanda nokuti zvinhu zvitsva (calcium carbonate) zvakagadzirwa.) zvakare.Izvo zvikamu zvikuru zveash 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.
