Low viscosity: 400 inonyanya kushandiswa kuzvidzora dhaka, asi inowanzotengeswa kunze kwenyika.
Chikonzero: Yakaderera viscosity, isina kunaka kuchengetwa kwemvura, asi yakanaka yekuenzanisa zvivakwa, yakakwira dhaka density.
Pakati uye yakaderera viscosity: 20000-40000 inonyanya kushandiswa kunamatira mataira, caulking agent, anti-crack mortar, thermal insulation bonding mortar, nezvimwe.
Zvikonzero: Kushanda kwakanaka, kushomeka kwemvura yakawedzerwa, uye yakakwira dhaka density.
1. Ndezvipi zvinoshandiswa zvakanyanya zvehydroxypropyl methylcellulose (HPMC)?
——A: HPMC inoshandiswa zvakanyanya mukuvaka, machira, masisitimu ekugadzira, ceramics, mishonga, chikafu, machira, kurima, zvizorwa, fodya uye mamwe maindasitiri.HPMC inogona kukamurwa kuita: giredhi rekuvaka, giredhi rekudya uye giredhi remishonga maererano nekushandisa.Parizvino, zvigadzirwa zvemumba zvakawanda giredhi rekuvaka.Mugiredhi rekuvaka, putty poda inoshandiswa muhuwandu hwakawanda, inenge 90% inoshandiswa kune putty poda, uye imwe yasara inoshandiswa sement mortar uye glue.
2. Ndeapi marudzi ehydroxypropyl methylcellulose (HPMC) aripo?Ndezvipi zvinoshandiswa?
--A: HPMC inogona kukamurwa kuita yekukurumidza mhando uye inopisa inonyungudika mhando.Zvigadzirwa zvepakarepo zvinopararira nekukurumidza mumvura inotonhora uye zvinonyangarika mumvura.Iyo mvura haina viscosity panguva ino nekuti HPMC inongopararira mumvura uye haina kunyungudika chaizvo.Mushure memaminitsi maviri, viscosity yemvura inowedzera zvishoma nezvishoma uye yakajeka viscous colloid inoumbwa.Zvigadzirwa zvinopisa zvinopisa zvinogona kukurumidza kupararira mumvura inopisa uye zvinonyangarika mumvura inopisa paunosangana nemvura inotonhora.Kana tembiricha yadzikira kusvika kune imwe tembiricha (chigadzirwa chekambani yedu i65 degrees Celsius), viscosity inoonekwa zvishoma nezvishoma kusvika pachena viscous colloid yaumbwa.Kupisa kunyungudika mhando inogona chete kushandiswa putty poda uye dhaka.Mumvura glue uye pendi, clumping ichaitika uye haigone kushandiswa.Rudzi rwekukurumidza rune huwandu hwakakura hwemaapplication.Inogona kushandiswa putty poda, dhaka, liquid glue, uye pendi pasina contraindications.
3. Ndedzipi nzira dzekunyungudutsa dzehydroxypropyl methylcellulose (HPMC)?
——Mhinduro: Nzira yekuchenesa mvura inopisa: Sezvo HPMC isinganyunguriki mumvura inopisa, HPMC inogona kuparadzirwa zvakaenzana mumvura inopisa panguva yekutanga uye kunyungudika nekukurumidza mushure mekutonhora.Nzira mbiri dzakajairika dzinotsanangurwa pasi apa:
1) Isa huwandu hunodiwa hwemvura inopisa mumudziyo uye kupisa kusvika ku70 ℃.Zvishoma nezvishoma wedzera hydroxypropyl methylcellulose neinononoka kumhanyisa.Pakutanga HPMC inoyangarara pamusoro pemvura, uye zvishoma nezvishoma inoumba slurry, uye inotonhorera nekukurudzira.
2).Wedzera 1/3 kana 2/3 yehuwandu hunodiwa hwemvura mumudziyo, kupisa kusvika ku70 ° C, kuparadzira HPMC maererano nenzira mu1), uye gadzirira slurry yemvura inopisa;wobva wawedzera huwandu hwakasara hwemvura inotonhorera kune inopisa mvura slurry.slurry mumvura, simbisa uye utonhodze musanganiswa.
Powder kusanganisa nzira: Sanganisa HPMC hupfu nehuwandu hwakawanda hwezvimwe zvinhu zvehupfu, nyatso sanganisa neblender, wobva wawedzera mvura kunyungudika.Panguva ino, iyo HPMC inogona kunyungudika uye haingasangani pamwe chete, nekuti pane zvishoma zvishoma zveHPMC muchikamu chimwe nechimwe.Kakona kadiki.Hupfu hunonyunguduka pakarepo paunosangana nemvura.-- Putty poda uye vagadziri vedhaka vanotora nzira iyi.Hydroxypropyl methylcellulose (HPMC) inoshandiswa sechinhu chakakora uye chekuchengetedza mvura mu putty powder mortar.
4. Nzira yekutonga sei kunaka kwehydroxypropyl methylcellulose (HPMC) nyore uye intuitively?
——Mhinduro: (1) Kuchena: Kunyange kuchena kusingaone kana HPMC iri nyore kushandisa, kana zvinopenya zvikawedzerwa panguva yekugadzira, zvinokanganisa kunaka kwayo.Zvisinei, zvigadzirwa zvakawanda zvakanaka zvine kuchena kwakanaka.(2) Fineness: Kunaka kweHPMC kunowanzoita 80 mesh uye zana mesh, ne120 mesh iri shoma.Yakawanda yeHPMC inogadzirwa muHebei ndeye 80 mesh.Kunaka kunenge kuri nani.(3) Light transmittance: Isa hydroxypropyl methylcellulose (HPMC) mumvura kuti iite yakajeka colloid, uye tarisa mwenje wayo.Iyo yakakwirira iyo mwenje transmittance, zviri nani, zvichiratidza kuti mune zvishoma zvisinganyungudika mukati.Kupinda kwemhepo kwemareactors akatwasuka kazhinji kuri nani pane kuya kwemareactor akachinjika, asi hazvigone kutaurwa kuti kunaka kwemaactor akatwasuka kuri nani pane emareactor akachinjika.Pane zvinhu zvakawanda zvinosarudza kunaka kwechigadzirwa.(4) Simba rinokwevera zvinhu pasi: Kukura kwesimba rinokwevera zvinhu pasi uye kurema, ndizvo zviri nani.Iyo chaiyo giravhiti inowanzoitika nekuda kweiyo yakakwira hydroxypropyl zvirimo.Iyo yakakwirira iyo hydroxypropyl yemukati, zviri nani kuchengetedza mvura.
5. Chii chinonzi hydroxypropyl methylcellulose (HPMC) mu putty powder?
——Mhinduro: Chiyero cheHPMC mumashandisirwo chaiwo chinosiyana zvichienderana nemamiriro ekunze, tembiricha, kunaka kwe calcium yemadota emunharaunda, uye fomula yekupinza.ty poda uye "hunhu hunodiwa nemutengi".Kazhinji kutaura, iri pakati pe4kg ne5kg.Semuenzaniso, yakawanda putty poda muBeijing ndeye 5 kg;yakawanda putty poda muGuizhou i5 kg muzhizha uye 4.5 kg muchando;
6. Chii chakakodzera viscosity yehydroxypropyl methylcellulose (HPMC)?
——Mhinduro: Putty powder inowanzoita 100,000 yuan, uye dhaka rinoda zvakawanda, saka 150,000 yuan inokwana.Uye inonyanya kukosha basa reHPMC ndeyekuchengetedza mvura, inoteverwa nekukora.Mune putty powder, chero bedzi iine mvura yakanaka yekuchengetedza uye yakaderera viscosity (70,000-80,000), zvakanaka.Zvechokwadi, iyo yakakwirira viscosity, zviri nani kuchengetedza mvura.Kana iyo viscosity inopfuura 100,000, iyo viscosity haina mhedzisiro pakuchengetedza mvura.
7. Ndeapi makuru ehunyanzvi zviratidzo zvehydroxypropyl methylcellulose (HPMC)?
--A: Hydroxypropyl yemukati uye viscosity, vazhinji vashandisi vane hanya nezve izvi zviviri zviratidzo.Iyo yakakwirira iyo hydroxypropyl yemukati, zviri nani kuchengetedza mvura.Nekupenya kwepamusoro, kuchengetwa kwemvura kunenge (kwete zvachose) zviri nani, uye nepamusoro viscosity, inoshandiswa zviri nani mumatope esimende.
8. Ndezvipi zvinhu zvakakosha zvehydroxypropyl methylcellulose (HPMC)?
—— A: Iyo huru yezvigadzirwa zve hydroxypropyl methylcellulose (HPMC): yakanatswa donje, methyl chloride, propylene oxide, zvimwe zvigadzirwa zvinosanganisira caustic soda, asidhi, toluene, isopropyl doro, nezvimwe.
9. Ndeipi basa guru reHPMC mukushandiswa kweputty powder?Zvine makemikari ega here?
——Mhinduro: HPMC ine mabasa makuru matatu ekukora, kuchengetedza mvura uye kuvaka muputty poda.Kukora: Cellulose inogona kuomesa kumiswa, chengeta mhinduro yunifomu uye kuramba kudonha.Kuchengetwa kwemvura: Ita kuti putty poda iome zvishoma nezvishoma uye ubatsire kuita kwegrey calcium pasi pekuita kwemvura.Kuvaka: Cellulose ine lubricating mhedzisiro uye inogona kuita iyo putty poda kuve nekushanda kwakanaka.HPMC haitore chikamu mune chero chemakemikari maitiro uye inongotamba basa rekubatsira.Apo putty powder inowedzerwa kumvura uye inoshandiswa kumadziro, kemikari inogadzirisa ichaitika.Sezvo chinhu chitsva chinoumbwa, iyo putty poda pamadziro inobviswa kubva pamadziro uye inogadzika kuita upfu isati yashandiswa.Izvi hazvishande nekuti chinhu chitsva (calcium carbonate) chakagadzirwa.) kumusoro.Izvo zvikamu zvikuru zve grey calcium powder ndezvi: musanganiswa weCa (OH) 2, CaO uye zvishoma zveCaCO3, CaO+H2O=Ca(OH)2 -Ca(OH)2+CO2=CaCO3↓+H2O Grey calcium. inonyungudika mumvura nemhepo CO2 Pasi pekuita kwe calcium carbonate, HPMC inongochengeta mvura uye inobatsira grey calcium kuti iite zviri nani, uye haibatanidzi mune chero maitiro pachayo.
10. HPMC isiri-ionic cellulose ether, saka chii chisiri-ionic?
A: Mukutaura kwevasina-ioni zvinhu zvisingaite ioni mumvura.Ionization ndiyo nzira iyo maelectrolytes anopatsanurwa kuita maion anochajiwa akasununguka mune zvimwe zvinonyungudutsa (semuenzaniso, mvura, doro).Semuenzaniso, sodium chloride (NaCl), munyu unodyiwa zuva rega rega, unonyungudika mumvura uye ionizes, ichigadzira yakasununguka mobile inochajiswa sodium ions (Na+) uye yakaipa chaji chloride ions (Cl).Kureva kuti, kana HPMC yakaiswa mumvura, haina kupatsanurwa mumaioni anochajiwa, asi iripo muchimiro chemolecular.
