Putty powder-hydroxypropyl methylcellulose

1. Ndeapi makuru ehunyanzvi zviratidzo zvehydroxypropyl methylcellulose (HPMC)?

Hydroxypropyl yemukati uye viscosity, vashandisi vazhinji vane hanya nezviratidzo zviviri izvi. Avo vane yakakwira hydroxypropyl zvemukati kazhinji vane zvirinani kuchengetedza mvura. Iyo ine high viscosity ine nani kuchengetedza mvura, zvishoma (kwete zvachose), uye iyo ine viscosity yakakwirira inoshandiswa zviri nani mumatope esimende.

2. Ndeipi basa guru rekushandiswa kweHPMC mu putty powder?

Mune putty poda, HPMC ine 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.

3. Pane hukama huripo pakati pekudonha kweputty powder uye HPMC?

Kurasikirwa kwehupfu kweputty powder kunonyanya kuenderana nehutano hwemadota e calcium, uye haina zvishoma zvekuita neHPMC. Iyo calcium ye grey calcium uye chiyero cheCaO uye Ca (OH) 2 mu grey calcium haina kukodzera, iyo inokonzera kurasikirwa kweupfu. Kana iine chimwe chinhu chekuita neHPMC, ipapo kuchengetwa kwemvura kwakashata kweHPMC kunokonzerawo kurasikirwa kweupfu.

4. Chii chinonzi hydroxypropyl methylcellulose (HPMC) mu putty powder?

Huwandu hweHPMC hunoshandiswa mukushanda kwekushandisa hunosiyana zvichienderana nemamiriro ekunze, tembiricha, kunaka kwekoni ash calcium, fomula yeputty powder uye 'mhando inodiwa nevatengi'.

5. Ndeipi yakakodzera viscosity yehydroxypropyl methylcellulose (HPMC)?

Kazhinji, 100,000 yuan yeputty powder inokwana, uye zvinodiwa padhaka 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 haina mhedzisiro pakuchengetedza mvura. hombe.

6. Ungasarudza sei yakakodzera hydroxypropyl methylcellulose (HPMC) nekuda kwezvinangwa zvakasiyana?

Kushandiswa kweputty powder: zvinodiwa zvakaderera, viscosity ndeye 100,000, yakakwana, chinhu chinokosha ndechokuchengeta mvura zvakanaka. Mushonga wedhaka: zvinodikanwa zvakakwirira, viscosity yakakwirira, 150,000 iri nani, glue application: zvigadzirwa zvekukurumidza zvinodikanwa, high viscosity.

7. Kushandiswa kweHPMC mu putty powder, chii chikonzero chezviputi muputty powder?

Mune putty poda, HPMC inobata mabasa matatu ekukora, kuchengetedza mvura uye kuvaka. Usatora chikamu mune chero maitiro. Zvikonzero zvebubbles:

1. Isa mvura yakawandisa.

2. Kana chikamu chepasi chisina kuoma, imwe tambo inokweshwa pamusoro, uye iri nyore kupupa.
