Chii chinonzi viscosity yehydroxypropyl methylcellulose hpmc?

Putty poda yemadziro emukati kazhinji ine viscosity ye100,000. Iyo simende dhaka ine zvakakwirira zvinodiwa pakugadzirisa, uye viscosity ye150,000 iri nyore kushandisa. Pamusoro pezvo, basa rinonyanya kukosha reHPMC kukiya mvura, ichiteverwa nekukora. Mu putty powder, kana kuchengetwa kwemvura kwakanaka uye viscosity yakaderera (7-80,000), inogonawo kuva nepamusoro pechisikigo viscosity uye zviri nani kuchengetedza mvura. Kana iyo viscosity inopfuura 100,000, iyo viscosity haina mhedzisiro pakuchengetedza mvura.

Chii chakakosha mhedzisiro yeHPMC mune putty poda, uye kana organic chemistry inoitika?

HPMC inotamba mabasa matatu ekukora, kuchengetedza mvura uye kuvaka mu putty poda.

Kukora: Methylcellulose inogona kuiswa pamwe nekuyangarara, aqueous mhinduro kuchengetedza yunifomu uye inowirirana kushanda uye kudzivirira kuyerera kunorembera.

Kuchengetwa kwemvura: Hupfu hwemukati hwemadziro hunooma zvishoma nezvishoma, uye yakawedzerwa calcium lime inoratidzwa mukushandiswa kwemvura.

Kuvakwa kweinjiniya: Methyl cellulose ine mafuta ekuzora, ayo anogona kuita kuti putty poda ive neyakanakisa engineering chimiro.

HPMC haina kubatanidzwa mune zvese makemikari shanduko asi chete mukuwedzera. Putty poda, pamadziro, ikemikari shanduko, nokuti kune makemikari matsva ekuchinja, iyo putty powder inobuda kunze kwemadziro, inokuya poda, uye inoshandisa zvakare nokuti makemikari matsva (calcium carbonate) akagadzirwa.

Zvikuru zvinoumba calcium fly ash ndezvi: Ca(o)2, Cao uye shoma shoma yeCaco3 compounds, Caoh2oCa(oh)2-Ca(oh)2caco3h2o lime inogona kushandurwa kuita calcium bicarbonate mumvura nemugasi, uku mpc iri. chete mvura inonyungudika Calcium fly ash iratidziro yakasimba, iyo pachayo isingabatanidzi mune chero fungidziro.

Chii chinofanira kutariswa mukushandiswa chaiko kwehukama pakati pe viscosity uye tembiricha yeHPMC?

Iyo viscosity yeHPMC inopindirana nekushisa, nemamwe mazwi, viscosity inowedzera nekuderera kwekushisa. Iyo viscosity yechigadzirwa, viscosity yechigadzirwa zvinoreva kuti mhinduro yayo ye2% iri patembiricha ye20 degrees Celsius, uye mhinduro dzebvunzo.

Mumashandisirwo chaiwo, kutariswa kunofanirwa kubhadharwa kune nzvimbo dzine tembiricha yakakura kusiyana pakati pezhizha nechando, uye inokurudzirwa zvakanyanya kushandisa yakaderera viscosity munguva yechando. Kana zvisina kudaro, viscosity yakaderera, viscosity ye cellulose ichawedzera, uye zvikwangwani zvichange zvichirema.

Medium viscosity: 75000-100000 yakakodzera putty poda
Chikonzero: kuchengetedza mvura zvakanaka

High viscosity: 150000-200000 inokodzera polystyrene particle insulation mortar uye inorganic insulation mortar.
Zvikonzero: high viscosity, yakaoma kubvisa simenti dhaka, kurasikirwa gloss, kuvandudzwa kuvaka.
