1. Ndeapi makuru ehunyanzvi zviratidzo zvehydroxypropyl methyl cellulose (HPMC)?
HPMC Hydroxypropyl kugutsikana uye viscosity, vakawanda vashandisi vane hanya nezviratidzo zviviri izvi.Kuchengetwa kwemvura kunowanzo kuve nani kune avo vane yakakwira hydroxypropyl zvemukati.High viscosity, kuchengetedza mvura, zvishoma (pane mhedziso) zviri nani, uye high viscosity, zviri nani kushandiswa mumatope esimende.
2. Ndeipi basa guru rekushandiswa kweHPMC mumadziro putty?
Mumadziro putty, HPMC ine mabasa matatu: kukora, kuchengetedza mvura uye kuvaka.
Kukora: Cellulose inogona kukobvu kumisa uye kuchengetedza mhinduro yunifomu, uye kuramba kudonha.Kuchengeta mvura: ita kuti madziro putty aome zvishoma nezvishoma, uye batsira grey calcium kuita pasi pekuita kwemvura.Kuvaka: Cellulose ine lubricating effect, iyo inogona kuita kuti madziro putty ave nekushanda kwakanaka.
3. Kudonha kwemadziro putty kune hukama neHPMC?
Kudonha kwemadziro putty kunonyanya kuenderana nemhando yeash calcium, asi kwete kune HPMC.Kana iyo calcium yakagadzirwa neash calcium uye chiyero cheCaO uye Ca (OH) 2 mu ash calcium isina kukodzera, inokonzera kurasikirwa kweupfu.Kana iine chekuita neHPMC, saka HPMC yekusachengeteka kwemvura inokonzeresa kudonha kwehupfu.
4. Yakawanda sei hydroxypropyl methyl cellulose (HPMC) mumadziro putty?
Huwandu hweHPMC hunoshandiswa mumashandisirwo chaiwo hunosiyana zvichienderana nemamiriro ekunze, tembiricha, yemunharaunda ash calcium quality, formula yemadziro putty, uye "mhando inodiwa nevatengi".Kazhinji kutaura, pakati pe4 kg ne5 kg.Semuenzaniso: Beijing wall putty inowanzoita 5 kg;Guizhou inowanzoita 5 kg muzhizha uye 4.5 kg muchando;Yunnan idiki, kazhinji 3 kg kusvika 4 kg zvichingodaro.
5. Ndeipi viscosity yakakodzera yehydroxypropyl methyl cellulose (HPMC)?
wall putty inowanzoita 100,000 , asi dhaka rinonyanya kudiwa, uye zvinotora 150,000 kushanda.Uyezve, basa rakakosha reHPMC kuchengetedza mvura, inoteverwa nekukora.Mumadziro putty , chero bedzi kuchengetwa kwemvura kwakanaka, viscosity yakaderera (70-80,000), zvinogonekawo, hongu, viscosity yakakwirira, uye hukama hwekuchengetedza mvura huri nani.Kana iyo viscosity inopfuura 100,000, iyo viscosity haina mhedzisiro pakuchengetedza mvura.
6. Nzira yekusarudza yakakodzera hydroxypropyl methylcellulose (HPMC) nekuda kwezvinangwa zvakasiyana?
Kushandiswa kwemadziro putty : zvinodiwa zvakaderera, viscosity ndeye 100,000, zvakakwana, chinhu chinokosha ndechokuchengeta mvura iri nani.Kushandiswa kwedhaka: zvinodiwa zvepamusoro, viscosity yakakwirira, zviri nani kudarika 150,000, kushandiswa kweglue: kukurumidza-kunyungudika zvigadzirwa, high viscosity.
7. Kushandiswa kweHPMC mumadziro putty, chii chinoita kuti madziro putty abudise mabubbles?
HPMC inobata mabasa matatu mumadziro putty: thickening, kuchengetedza mvura uye kuvaka.Usatora chikamu mune chero maitiro.Zvikonzero zvebubbles:
(1) Mvura yakawandisa inoiswa.
(2) Chitubu chepasi hachina kuoma, uye chimwe chipande chinokweshwa, icho chiri nyorewo kupupuma furo.
