Hydroxypropyl methyl cellulose(hpmc)inowanzoshandiswa muputty powder ine viscosity ye100000, nepo dhaka rine zvinodiwa zvakanyanya zveviscosity uye inofanira kusarudzwa ine viscosity ye150000 kuti ishandiswe zviri nani. Basa rakakosha rehydroxypropyl methyl cellulosendiko kuchengetedza mvura, kuchiteverwa nekukora. Nokudaro, mu putty powder, chero bedzi kuchengetwa kwemvura kwasvika uye viscosity yakaderera, zvinogonekawo. Kazhinji kutaura, iyo yakakwirira viscosity, zviri nani kuchengetedza mvura. Nekudaro, kana iyo viscosity inopfuura 100000, mhedzisiro yeviscosity pakuchengetedza mvura haina kukosha.

Jufu Building Material GradeHydroxypropyl Methyl CelluloseInosiyaniswa neViscosity, inowanzogoverwa mumhando dzinotevera:

1. Low viscosity: 400 viscosity cellulose, inonyanya kushandiswa kuzvidzora dhaka. Yakaderera viscosity, yakanaka kuyerera, uye mushure mekuwedzera, ichadzora pamusoro pekuchengetedza mvura. Kubuda ropa hakusi pachena, shrinkage idiki, uye kuputika kunoderedzwa. Inogona zvakare kuramba sedimentation, kuwedzera kuyerera uye kupomba.
2. Pakati pepakati kusvika pakadzika viscosity: 20000 kusvika 50000 viscosity cellulose, inonyanya kushandiswa kune zvigadzirwa zvegypsum uye majoint fillers. Low viscosity, kuchengetwa kwemvura kwakanaka, kushanda zvakanaka, uye kuwedzera kwemvura yakaderera,
3. Medium viscosity: 75000-100000 viscosity cellulose, inonyanya kushandiswa mukati nekunze kwemadziro putty. Mwero viscosity, kuchengetwa kwemvura kwakanaka, uye yakanaka yekuvaka drape.
4. High viscosity: 150000 kusvika 200000 yuan, inonyanya kushandiswa polystyrene particle insulation mortar powder material, vitrified micro bead insulation mortar ine high viscosity uye kuchengetedza mvura. Iyo dhaka haisi nyore kudonha uye kurembera, kuvandudza kuvaka.
Kazhinji kutaura, iyo yakakwirira viscosity, zviri nani kuchengetedza mvura. Nokudaro, vatengi vakawanda vanosarudza kushandisa medium viscosity cellulose (75000-100000) panzvimbo yepakati yakaderera viscosity cellulose (20000-50000) kuderedza kuwanda kwekuwedzera uye kutonga mari.
Iyo viscosity yeHPMCiri inversely proportional to tembiricha, nemamwe mazwi, viscosity inowedzera nekuderera kwekushisa. Iyo viscosity yechigadzirwa inoreva kuti mhinduro yayo ye2% iri patembiricha ye20 degrees Celsius, uye mhinduro dzebvunzo dzakarurama.
Mumashandisirwo chaiwo, kutariswa kunofanirwa kubhadharwa kune nzvimbo dzine tembiricha yakakura kusiyana pakati pezhizha nechando, uye zvinokurudzirwa kushandisa yakaderera viscosity munguva yechando. Zvikasadaro, kana viscosity yakaderera, viscosity ye cellulose inowedzera uye mavanga anorema.
