Kusviba kwakaderera: 400 inonyanya kushandiswa pakugadzira dhaka rinozvienzanisa, asi rinowanzo tengwa kunze kwenyika.
Chikonzero: Kusviba kwakaderera, kusachengetedza mvura zvakanaka, asi hunhu hwakanaka hwekuenzana, huwandu hwakawanda hwemortar.
Viscosity yepakati nepasi: 20000-40000 inonyanya kushandiswa pakunamira mataira, caulking agent, anti-crack mortar, thermal insulation bonding mortar, nezvimwewo.
Zvikonzero: Kushanda zvakanaka, mvura shoma yakawedzerwa, uye huwandu hwakawanda hwedhaka.
1. Ndedzipi nzira huru dzekushandisa hydroxypropyl methylcellulose (HPMC)?
——A: HPMC inoshandiswa zvakanyanya muzvinhu zvekuvaka, machira ekuputira, maresini ekugadzira, zviumbwa zvedoro, mishonga, chikafu, machira, kurima, zvizoro, fodya nedzimwe nzvimbo. HPMC inogona kukamurwa kuita: giredhi rekuvaka, giredhi rezvekudya uye giredhi remishonga zvichienderana nekushandiswa. Parizvino, zvigadzirwa zvakawanda zvemumba ndezve giredhi rekuvaka. Mugiredhi rekuvaka, putty powder inoshandiswa zvakanyanya, inenge 90% inoshandiswa putty powder, uye yasara inoshandiswa simende mortar neglue.
2. Kune mhando ngani dzehydroxypropyl methylcellulose (HPMC)? Ndedzipi nzira dzadzinoshandisa?
——A: HPMC inogona kukamurwa kuita mhando yekukurumidza uye mhando yekupisa inonyunguduka. Zvigadzirwa zvekukurumidza zvinopararira nekukurumidza mumvura inotonhora uye zvinonyangarika mumvura. Mvura yacho haina viscosity panguva ino nekuti HPMC inongopararira mumvura chete uye hainyunguduke chaizvo. Mushure memaminitsi angangoita maviri, viscosity yemvura inowedzera zvishoma nezvishoma uye colloid yakajeka inoumbwa. Zvigadzirwa zvinonyunguduka zvinopisa zvinogona kupararira nekukurumidza mumvura inopisa uye zvinonyangarika mumvura inopisa kana zvasangana nemvura inotonhora. Kana tembiricha yadzikira kusvika kune imwe tembiricha (chigadzirwa chekambani yedu chiri 65 degrees Celsius), viscosity inoonekwa zvishoma nezvishoma kusvika colloid yakajeka inonyunguduka yaumbwa. Hot melt type inogona kushandiswa chete kune putty powder nemortar. Mune liquid glue nependi, clump inoitika uye haigone kushandiswa. Type yekukurumidza ine mashandisirwo akasiyana-siyana. Inogona kushandiswa kune putty powder, mortar, liquid glue, uye pendi pasina chero zvinopesana.
3. Ndedzipi nzira dzekunyungudutsa dzehydroxypropyl methylcellulose (HPMC)?
——Mhinduro: Nzira yekunyungudutsa mvura inopisa: Sezvo HPMC isinganyungudike mumvura inopisa, HPMC inogona kunyungudika zvakaenzana mumvura inopisa pakutanga uye inonyungudika nekukurumidza mushure mekutonhora. Nzira mbiri dzakajairika dzinotsanangurwa pazasi:
1) Isa mvura inopisa inodiwa mumudziyo woipisa kusvika pa70℃. Wedzera zvishoma nezvishoma hydroxypropyl methylcellulose uchikurunga zvishoma nezvishoma. Pakutanga HPMC inoyangarara pamusoro pemvura, yozogadzira slurry zvishoma nezvishoma, yotonhorera nekukurunga.
2). Wedzera 1/3 kana 2/3 yehuwandu hwemvura hunodiwa mumudziyo, upise kusvika 70°C, paradzira HPMC zvichienderana nenzira iri mu1), uye gadzira slurry yemvura inopisa; wobva wawedzera huwandu hwemvura inotonhora yasara muslurry yemvura inopisa. slurry mumvura, kurunga wotonhodza musanganiswa.
Nzira yekusanganisa upfu: Sanganisa upfu hweHPMC nezvimwe zvinhu zvakawanda zvine upfu, sanganisa zvakanaka uchishandisa blender, wobva wawedzera mvura kuti inyungudike. Panguva ino, HPMC inogona kunyungudika uye haizounganidzwe, nekuti pane HPMC shoma muchikamu chimwe nechimwe. Kona diki. Upfu hunonyungudika pakarepo kana wasangana nemvura. ——Vagadziri vePutty powder nemortar vanoshandisa nzira iyi. Hydroxypropyl methylcellulose (HPMC) inoshandiswa sechinhu chinosimbisa uye chinochengetedza mvura mumortar yeputty powder.
4. Ungatonga sei mhando yehydroxypropyl methylcellulose (HPMC) zviri nyore uye nenzira isinganzwisisike?
——Mhinduro: (1) Kuchena: Kunyange zvazvo kuchena kusingasarudze kana HPMC iri nyore kushandisa, kana zvikaiswa zvinopenya panguva yekugadzira, zvinokanganisa kunaka kwayo. Zvisinei, zvigadzirwa zvakawanda zvakanaka zvine kuchena kwakanaka. (2) Kuchena: Kuchena kweHPMC kunowanzova 80 mesh uye 100 mesh, ne120 mesh iri shoma. Yakawanda yeHPMC inogadzirwa muHebei i80 mesh. Kuchena kwakanyanya ndiko kuri nani. (3) Kutumira chiedza: Isa hydroxypropyl methylcellulose (HPMC) mumvura kuti igadzire colloid yakajeka, uye tarisa kutumirwa kwayo kwechiedza. Kutumira chiedza kwakakwira, ndiko kuri nani, zvichiratidza kuti mune zvinhu zvisinganyunguduke mukati. Kupinda kwemhepo kwema vertical reactors kazhinji kuri nani pane kwema horizontal reactors, asi hazvigone kutaurwa kuti mhando yema vertical reactors iri nani pane yema horizontal reactors. Pane zvinhu zvakawanda zvinosarudza mhando yechigadzirwa. (4) Huremu hwakanyanya: Huremu hwakanyanya uye huremu hwakanyanya, zviri nani. Simba guru remuchadenga rinowanzo kukonzerwa nehuwandu hwakawanda hwehydroxypropyl mairi. Kana huwandu hwakawanda hwehydroxypropyl, kuchengetedza mvura kuri nani.
5. Chii chinonzi hydroxypropyl methylcellulose (HPMC) muputty powder?
——Mhinduro: Chiyero cheHPMC mukushandiswa chaiko chinosiyana zvichienderana nemamiriro ekunze, tembiricha, mhando yecalcium yemuno, uye fomura yekuisa. ty powder uye "hunhu hunodiwa nemutengi". Kazhinji, iri pakati pe4kg ne5kg. Semuenzaniso, putty powder yakawanda muBeijing i5kg; putty powder yakawanda muGuizhou i5kg muzhizha uye 4.5 kg muchando;
6. Chii chinonzi viscosity yakakodzera yehydroxypropyl methylcellulose (HPMC)?
——Mhinduro: Putty powder inowanzo dhura 100,000 yuan, uye mortar inoda yakawanda, saka 150,000 yuan yakakwana. Uye basa guru reHPMC kuchengetedza mvura, richiteverwa nekukora. Muputty powder, chero bedzi iine mvura yakanaka yekuchengetedza uye viscosity yakaderera (70,000-80,000), hazvina kuipa. Ehe, viscosity yakakwira, kuchengetedza mvura kwakanyanya. Kana viscosity ikadarika 100,000, viscosity haina simba guru pakuchengetedza mvura.
7. Ndezvipi zviratidzo zvikuru zve hydroxypropyl methylcellulose (HPMC)?
——A: Kuwanda kwehydroxypropyl uye viscosity, vashandisi vazhinji vanonetseka nezvezviratidzo zviviri izvi. Kana hydroxypropyl yakawanda, kuchengetedza mvura kuri nani. Kana viscosity yakawanda, kuchengetedza mvura kuri nani (kwete zvachose), uye kana viscosity yakawanda, zviri nani kushandisa mumota wesimende.
8. Ndezvipi zvinhu zvikuru zve hydroxypropyl methylcellulose (HPMC)?
—— A: Zvinhu zvikuru zve hydroxypropyl methylcellulose (HPMC): donje rakanatswa, methyl chloride, propylene oxide, zvimwe zvinhu zvinosanganisira caustic soda, acid, toluene, isopropyl alcohol, nezvimwewo.
9. Basa guru reHPMC mukushandisa putty powder nderei? Rine mhedzisiro yemakemikari here?
——Mhinduro: HPMC ine mabasa matatu makuru ekukora, kuchengetedza mvura uye kuvaka mupudhi yeputty. Kukora: Cellulose inogona kukora kumisa, kuchengetedza mhinduro yakafanana uye kudzivirira kudzika. Kuchengetwa kwemvura: Ita kuti putty powder iome zvishoma nezvishoma uye inobatsira kuita kwe grey calcium pasi pekushanda kwemvura. Kuvaka: Cellulose ine mafuta ekuzora uye inogona kuita kuti putty powder ishande zvakanaka. HPMC haibatanidzi mune chero maitiro emakemikari uye inongobatsira chete. Kana putty powder yawedzerwa mumvura uye ikaiswa pamadziro, chemical reaction inoitika. Sezvo chinhu chitsva chichiumbwa, putty powder iri pamadziro inobviswa pamadziro uye inokuyiwa kuita upfu usati washandisa. Izvi hazvishande nekuti chinhu chitsva (calcium carbonate) chaumbwa. ) kumusoro. Zvikamu zvikuru zveupfu hwekarusiyamu yegrey ndeizvi: musanganiswa weCa(OH)2, CaO uye huwandu hushoma hweCaCO3, CaO+H2O=Ca(OH)2 -Ca(OH)2+CO2=CaCO3↓+H2O Karusiyamu yegrey inonyungudika mumvura nemhepo CO2 Pasi pekushanda kwecalcium carbonate, HPMC inongochengeta mvura chete uye inobatsira calcium yegrey kuti iite zviri nani, uye haibatanidzi mune chero chiitiko pachayo.
10. HPMC iether isina ionic cellulose, saka chii chinonzi non-ionic?
A: Mukutaura kwevanhuwo zvavo, ma non-ion zvinhu zvisingaite ioni mumvura. Ionization inzira iyo ma electrolytes anopatsanurwa kuita ma ioni ane chaji anofamba zvakasununguka mune zvimwe zvinonyungudutsa (semuenzaniso, mvura, doro). Semuenzaniso, sodium chloride (NaCl), munyu unodyiwa zuva rega rega, unonyunguduka mumvura woita ioni, zvichigadzira ma ioni ane chaji anofamba zvakasununguka (Na+) uye ma ioni ane chaji akashata (Cl). Kureva kuti, kana HPMC ikaiswa mumvura, haipatsanurwi kuita ma ioni ane chaji, asi inovapo muchimiro chemamorekuru.
