Hydroxypropyl methylcellulose yekupfapfaidza pamadziro!

Zvigadzirwa zveHydroxypropyl methylcellulose zvekuvaka zvinoshandiswa zvakanyanya kuvandudza mashandiro ezvivakwa zve hydraulic, senge simende uye gypsum. Mumasimende-akavakirwa madhaka, inovandudza kuchengetedza kwemvura, inorebesa kururamisa uye nguva yakavhurika, uye inoderedza kusagika.

a. Kuchengetedza mvura

Hydroxypropyl methylcellulose yekuvaka inodzivirira hunyoro kubva pakupinda mumadziro. Nhamba yakakodzera yemvura inoramba iri mudhaka, kuitira kuti simiti ive nenguva yakareba yekunyorova. Kuchengetwa kwemvura kwakaenzana ne viscosity ye cellulose ether solution mudhaka. Iyo yakakwirira viscosity, zviri nani kuchengetedza mvura. Kamwe mamorekuru emvura akawedzera, kuchengetwa kwemvura kunoderera. Nokuti nokuda kwechiyero chakafanana chekuvaka-specific hydroxypropyl methylcellulose solution, kuwedzera kwemvura kunoreva kuderera kwe viscosity. Kuvandudzwa kwekuchengetedza mvura kuchaita kuti kuwedzerwa kwenguva yekuporesa kwedhaka riri kuvakwa.

b. Kuvandudza kuvaka

Iko kushandiswa kwehydroxypropyl methylcellulose HPMC kunogona kuvandudza kuvakwa kwedhaka.

c. Kugona kuzora mafuta

Zvese zvinopinda mumhepo zvinoshanda seanonyorovesa nekudzikisa kusimba kwepasi uye kubatsira mafaindi ari mudhaka kuti apararire kana asanganiswa nemvura.

d. Anti-sagging

Doka rakanaka risingapindi muvhu (sag-resistant motar) zvinoreva kuti kana ikaiswa mumitsetse mikobvu hapana ngozi yekusaga kana kuyerera. Sag kuramba inogona kuvandudzwa nekuvaka-chaiyo hydroxypropyl methylcellulose. Iyo yekuvaka-chaiyo hydroxypropyl methylcellulose inogadzirwa neShandong Chuangyao Kambani inogona kupa zvirinani anti-sagging zvimiro zvedhaka.

e. Bubble content

Yakakwira mhepo bubble yemukati inoburitsa zvirinani goho redhaka uye kushanda, kuderedza kutsemuka kuumbwa. Iyo inoderedzawo kukosha kwekusimba, zvichikonzera "liquefaction" chiitiko. Mhepo bubble zvemukati zvinowanzoenderana nekukurudzira nguva.

Zvakanakira zve hydroxypropyl methylcellulose mukuvaka zvinhu zvekuvaka:

Hydroxypropyl methylcellulose ine zvimiro zvayo zvakasiyana mukushandiswa kwezvinhu zvekuvakisa, kubva mukusanganiswa kusvika pakupararira kusvika pakuvaka, sezvinotevera:

Composite uye kugadzirisa:

1. Zviri nyore kusanganisa nehupfu hwakaoma.

2. Iine maitiro ekupararira kwemvura inotonhora.

3. Simbisa zvimedu zvakasimba zvinobudirira, zvichiita kuti musanganiswa uwedzere uye uwedzere kufanana.

Kupararira uye kusanganisa:

1. Mushonga wakaoma wakasanganiswa une hydroxypropyl methylcellulose unogona kusanganiswa nyore nyore nemvura.

2. Kurumidza kuwana kuwirirana kunodiwa.

3. Kuparara kwe cellulose ether kunokurumidza uye pasina mapundu.

Kuvakwa kwepamhepo:

1. Kuvandudza lubricity uye plasticity kuti uwedzere machinability uye kuita kuti chigadzirwa chive chiri nyore uye nekukurumidza.

2. Kuvandudza maitiro ekuchengetedza mvura uye kuwedzera nguva yekushanda.

3. Inobatsira kudzivirira vertical kuyerera kwedhaka, dhaka uye mataira. Rebesa nguva yekutonhora uye uvandudze kushanda zvakanaka.

Kupedza kuita uye kutaridzika:

1. Kuvandudza simba rekubatanidza rematairi ekunamatira.

2. Kuvandudza anti-crack shrinkage uye anti-kuparuka simba rematope uye bhodhi joint filler.

3. Kuvandudza mhepo yemukati mudhaka uye kuderedza zvakanyanya mukana wekutsemuka.

4. Kuvandudza kutaridzika kwezvigadzirwa zvakapedzwa.

5. Inogona kuwedzera vertical flow resistance yeadhesives tile.

Hydroxypropyl methylcellulose (HPMC) isiri-ionic cellulose ether yakagadzirwa kubva mukotoni yakachena kuburikidza nehurongwa hwemakemikari maitiro. Hydroxypropylmethylcellulose (HPMC) inonhuhwirira, isinganakidze, isina chepfu chena poda inogona kunyungudutswa mumvura inotonhora kuti iite yakajeka viscous mhinduro. Iine maitiro ekukora, kusunga, kuparadzira, emulsifying, firimu-kuumba, kumisa, adsorbing, gelling, pamusoro pekushanda, kuchengetedza unyoro nekudzivirira colloid.
