Hydroxypropyl Methylcellulose (HPMC) yakakosha cellulose ether ine huwandu hwakawanda hwekushandisa muindasitiri yekuvaka. Iyo inonyungudika nemvura polymer musanganiswa unowanikwa nekemikari kushandura yakasikwa cellulose. Iine mvura yakanaka solubility, thickening, film-forming, bonding, lubricity uye mamwe maitiro, saka inotamba zvakasiyana-siyana zvakakosha muzvinhu zvekuvaka.
1. Cement dhaka uye kongiri
Mune simende dhaka uye kongiri, HPMC inoshandiswa zvakanyanya seyakakora, inochengetedza mvura uye inosunga. Mabasa ayo makuru anosanganisira:
Kukora mhedzisiro: HPMC inogona kuwedzera viscosity yesamende dhaka kana kongiri, nekudaro ichivandudza kuita kwekuvaka uye kuita kuti zvive nyore kuparadzira nekushanda. Mukuwedzera, iyo yakakora dhaka inogona kunamatira zviri nani kune substrate uye kuderedza mukana wehupfu uye kudonha.
Kuchengetedza kwemvura maitiro: HPMC ine simba rekuchengetedza mvura yakasimba, iyo inogona kuderedza kurasikirwa kwemvura mudhaka kana kongiri, kuwedzera nguva ye hydration reaction nguva ye simenti, uye nokudaro inovandudza simba rekupedzisira uye kusimba. Ichi chimiro chinonyanya kukosha munzvimbo dzakaoma kana dzekushisa kwepamusoro, sezvo zvinogona kudzivirira kuputika uye kusakwana kuoma kunokonzerwa nekuoma kusati kwapera simenti.
Anti-sagging mhedzisiro: Kana uchivaka panzvimbo dzakatwasuka, HPMC inogona kudzivirira dhaka kana bhandi kubva pakutsvedza pasi, kuchengetedza ukobvu hweyunifomu uye kufukidzwa kwakanaka.
2. Tile adhesives
Mumataira anonamira, basa reHPMC rakakosha zvikuru. Haisi kungovandudza kusungirirwa kwekunamatira, asiwo kunowedzera kushanda panguva yekuvaka. Kunyanya, inoratidzwa sezvinotevera:
Kuvandudza adhesion: HPMC inosimudzira kunamatira pakati pematairi anonamira uye mataira uye substrates, kuve nechokwadi kugadzikana uye kusimba kwematiles mushure mekuisa.
Kuvandudza mashandiro ekuvaka: HPMC inogona kuwedzera nguva yekuvhura yekunamatira mataira, ndiko kuti, kuwedzera nguva iyo nzvimbo yematairi inogona kugadziriswa pamberi pekunamatira kwaoma, iyo yakakosha kune vashandi vekuvaka uye inogona kuve nechokwadi chechokwadi chekuisa mataira.
Anti-slip: Yemataira akakura-saizi kana pakuvaka panzvimbo yakatwasuka, HPMC inogona kudzivirira kutsvedza kwemataira, nekudaro ichivandudza kunaka kwekuvaka.
3. Kunze kwemadziro ekudzivirira system
Mune yekunze madziro ekudzivirira system, HPMC inoitawo basa rekuchengetedza mvura, kukora uye kubatana. Iyo yekunze yekudzivirira sisitimu inoda kuti zvinhu zvekuvaka zvive zvakanaka zvekuchengeta mvura kuti ive nechokwadi chekuti dhaka rekubatanidza harizokundikane nekuda kwekurasikirwa kwemvura yakawandisa panguva yekuvaka uye kurapa matanho. Kuwedzerwa kweHPMC kunovandudza kushanda, kupeta uye kutsemuka kuramba kwedhaka, nekudaro kunatsiridza kunaka kwekuvaka uye kusimba kweiyo yese insulation system.
4. Kuzvimiririra pasi zvinhu
Mune yekuzvimisikidza pasi zvinhu, HPMC inoita basa rekudzora fluid uye kugadzirisa kuchengetwa kwemvura. Ichi chinhu chinoda kuenzana panguva yekuvaka, asi haigone kuburitsa yakawandisa sedimentation kana stratification. Iko kukora mhedzisiro yeHPMC inogona kuchengetedza kufanana kwechinhu pasina kukanganisa kuyerera, kuve nechokwadi chekuti pasi pepasi pakatsetseka uye yakatsetseka.
5. Putty powder
HPMC inoshandiswawo zvakanyanya mu putty poda yemukati nekunze madziro ezvivakwa. Inogona kuvandudza kuvakwa uye kusimba kweputty poda, kuwedzera kunamatira kwayo kumadziro, uye kugadzirisa nguva yekuomesa uye kutsemuka kuramba kweputty poda. Kunyanya mumamiriro ekunze akaoma, HPMC inogona kunyatsodzivirira kuputika kwepamusoro kana kudonha kunokonzerwa nekukurumidza kurasikirwa kwemvura yeputty powder.
6. Zvimwe zvikumbiro
Pamusoro pekushandiswa kukuru kuri pamusoro apa, HPMC inoitawo basa mune dzimwe nzvimbo dzekuvaka, senge gypsum-based products, waterproof coatings, grouting materials, sealants, etc. Its multifunctional properties senge kukora, kuchengetedza mvura, uye bonding inozviita. chinhu chikuru chekuwedzera mune zvekuvaka.
Hydroxypropyl methylcellulose ine huwandu hwakawanda hwemashandisirwo akakosha muindasitiri yekuvaka. Iyo inovandudza zvakanyanya kunaka uye kugona kwekuvaka kwezvivakwa zvekuvaka nekuvandudza mashandiro ekuvaka esimende-yakavakirwa uye gypsum-yakavakirwa zvinhu, kuwedzera nguva yekushanda, kuwedzera chisungo, uye nekuvandudza kutsemuka kuramba. Naizvozvo, tarisiro yekushandiswa kweHPMC mukuvaka kwemazuva ano yakafara kwazvo, uye nekuenderera mberi kwekuvandudza tekinoroji yekuvaka, basa reHPMC richave rine mukurumbira.
