HPMC muKuvaka

Hydroxypropyl methyl cellulose HPMC ndeye yakasikwa polymer material cellulose seyakagadzirwa, kuburikidza nenhevedzano yemakemikari kugadzirisa uye yakagadzirwa neasiri-ionic cellulose ether. Ihwo hupfu husina kunhuwa, husina chepfu, husina muchetura hupfu hunowedzera huchienda kumvura inotonhora. Nekukora, kunamatira, kupararira, emulsification, kuumbwa kwemafirimu, kumiswa, adsorption, gel, chiitiko chepamusoro, kuchengetedza unyoro uye kuchengetedzwa kwecolloidal, nezvimwewo Hydroxypropyl methyl cellulose HPMC, methyl cellulose MC inogona kushandiswa mukuvaka zvinhu, indasitiri yekupfekedza, synthetic resin, Ceramic indasitiri, mushonga, chikafu, machira, kurima, makemikari emazuva ese uye mamwe maindasitiri.

Zvivakwa zveHPMC zvinoshandiswa muKuvaka
1. Kuchengeta mvura
Hydroxypropyl methyl cellulose HPMC yekuvaka inodzivirira kunyura kwemvura neiyo substrate, uye mvura inofanirwa kuchengetwa mupurasita zvakanyanya sezvinobvira panguva yekupedzwa kwegypsum solidification. Ichi chivakwa chinozivikanwa sekuchengetwa kwemvura, uye yakaenzana neviscosity yechivakwa chakananga hydroxypropyl methyl cellulose HPMC mhinduro mustucco, iyo yakakwira viscosity yemhinduro, iyo yakakwirira yekuchengeta mvura.
Pakangowedzera huwandu hwemvura, simba rekuchengetedza mvura rinodzikira, nekuti yakawedzera mvura yakanyungudutsa kuvakwa kwehydroxypropyl methyl cellulose HPMC mhinduro, zvichikonzera kudzikira kweviscosity.
2. Sag resistance
Stucco inoshingirira kuyerera uye kurembera inobvumira muvaki kuisa jira gobvu pasina kuyerera kwakamira, izvo zvinoreva zvakare kuti stucco pachayo ndeye thixotropic, zvikasadaro inotsvedza ichidzika panguva yekuvaka.
3. Deredza viscosity, nyore kuvaka
Nekuwedzera akasiyana ekuvaka akakosha hydroxypropyl methyl cellulose HPMC zvigadzirwa, yakaderera viscosity uye nyore kuvaka inogona kuwanikwa kubva gypsum plaster, uchishandisa yakaderera viscosity level chivakwa chakatsaurirwa hydroxypropyl methyl cellulose HPMC, zvishoma viscosity uye nyore kuvaka, zvisinei, yakaderera viscosity chivakwa chakatsaurirwa. hydroxypropyl methyl cellulose HPMC yekuchengeta mvura kugona haina simba, inoda kukwidza yakawedzera huwandu.
4. Kukwanisa kukura mwero we stucco
Nokuda kwehuwandu hwakatarwa hwedhaka rakaoma, zvinowedzera hupfumi kuti hubudise huwandu hwehutu hwakanyorova, hunogona kuwanikwa nekuwedzera mamwe mvura uye mabhubhu. Asi mvura yakawandisa uye mabhubhu zvinogona kukuvadza simba.

(2)inopa high bond simba.

9.Extrusion kuumba simende ndiro
(1) ine yakabatana yakakwira uye lubricity, inosimudzira mashandiro ezvigadzirwa zveextrusion.
(2) Kuvandudza simba rakasvibirira, kusimudzira hydration kurapa maitiro, kuwedzera goho rechigadzirwa chakapedzwa.

10.premixed mortar
mu premixed dhaka kuchengetwa kwemvura kuri nani pane zvakajairwa zvigadzirwa, kuve nechokwadi chakazara hydration ye inorganic simende zvinhu, zvakanyanya kudzivirira kuoma nekukurumidza kunokonzerwa nekudzikira kwesimba rebhondi, uye kuomesa shrinkage kunokonzerwa nekutsemuka. HPMC zvakare ine imwe mhepo intraining mhedzisiro, premixed dhaka yakakosha HPMC zvigadzirwa, mhepo inopinza yakaringana, yunifomu uye mabhuru madiki, inogona kuvandudza simba uye kupenya kwe premixed dhaka. Premixed mortar yakakosha HPMC zvigadzirwa zvine imwe inonoke mhedzisiro, inogona kurebesa nguva yekuvhura ye premixed dhaka, kuderedza kuoma kwekuvaka.
