Nezve hydroxypropyl methylcellulose panguva yekushandiswa kweputty powder

1. Matambudziko anowanzo mu putty powder

[Kurumidza kuomesa] Izvi zvinonyanya kuenderana nehuwandu hweash calcium powder yakawedzerwa (yakakura kwazvo, inogona kuderedza zvakakodzera huwandu hwemadota calcium powder inoshandiswa muputty formula) uye chiyero chekuchengetedza mvura yehydroxypropyl methylcellulose (HPMC), uye iyo zvakare ine hukama neIzvo zvine chekuita nekuoma kwemadziro.

[Kukwenya uye kupeta] Izvi zvine hukama nehuwandu hwekuchengetedza mvura. Hydroxypropyl methylcellulose (HPMC) ine yakaderera viscosity uye inowanzoitika kune iyi mamiriro kana huwandu hwekuwedzera hudiki.

[Powder kubviswa kwemukati wemadziro putty powder] Izvi zvinoenderana nehuwandu hweash calcium powder yakawedzerwa (huwandu hweash calcium powder muputty formula idiki kana kuchena kweash calcium powder yakaderera, uye huwandu hwemadota. calcium powder mu putty powder formula inofanira kuwedzerwa zvakakodzera) Panguva imwecheteyo, inobatanidzawo nehuwandu uye hutano hwehydroxypropyl methylcellulose (HPMC), iyo inoratidzwa muhuwandu hwekuchengetedza mvura kwechigadzirwa. Mvura yekuchengetedza mvura yakaderera, uye calcium oxide mudota calcium powder haina kunyatsogadziriswa Calcium hydroxide conversion hydration) nguva haina kukwana, inokonzerwa.

[Blistering] Izvi zvine chekuita nekuoma kwemvura uye kupfava kwemadziro, uye zvine chekuita nekuvakwa.

[Mapini anooneka] Izvi zvine chekuita neselulosi, iyo isina kusimba yekugadzira firimu, uye zvakare tsvina iri muhydroxypropyl methylcellulose (HPMC) inoita zvishoma neash calcium. Kana maitiro acho akaoma, iyo putty poda ichaonekwa tofu Slag state. Haikwanise kuiswa pamadziro, uye haina simba rakabatana panguva imwe chete. Uye zvakare, zvigadzirwa zvakaita sehydroxypropyl methylcellulose (HPMC) yakasanganiswa necarboxymethyl boka zvakare inoonekwa mune ino mamiriro.

[Mapako anoputika uye mapinhole anooneka] Izvi zviri pachena kuti zvine hukama nekunetsana kwemvura pamusoro peiyo hydroxypropyl methylcellulose (HPMC) aqueous solution. Iko kushushikana kwemvura patafura yehydroxyethyl aqueous solution haisi pachena. Zvingava zvakanaka kuita finishing treatment.

[Iyo putty iri nyore kutsemuka nekushanduka yero mushure mekuomeswa] Izvi zvine chekuita nekuwedzerwa kwehuwandu hwakawanda hweash calcium powder. Kana iyo yakawanda yeash calcium powder yakawedzerwa zvakanyanya, kuoma kweputty powder kuchawedzera mushure mekuoma. Kuomarara chete pasina kuchinjika kuchatsemuka nyore, kunyanya Iyo inonyanya kuputika kana ichiiswa pasi pesimba rekunze. Iyo inobatanawo nehuwandu hwehuwandu hwe calcium oxide mu ash calcium powder.

2. Sei putty powder inova mutete mushure mekuwedzera mvura?

Hydroxypropyl methylcellulose (HPMC) inoshandiswa sechinhu chakakora uye chinochengeta mvura mugirisi. Nekuda kweiyo thixotropy yehydroxypropyl methylcellulose (HPMC), iyo hydroxypropyl methylcellulose mu putty powder Kuwedzerwa kweHPMC kwakakonzerawo thixotropy mushure mekuwedzera mvura kune putty. Iyi thixotropy inokonzerwa nekuparadzwa kwemaitiro akasununguka akabatanidzwa ezvikamu muputty powder. Ichi chimiro chinomuka pakuzorora uye chinoputsika pasi pekunetseka. Izvi zvinoreva kuti, viscosity inoderera pasi pekukurudzira, uye viscosity inopora kana yakamira.

3. Ndechipi chikonzero nei putty iri kuremerwa mukukwesha?

Muchiitiko ichi, viscosity yehydroxypropyl methylcellulose (HPMC) inowanzo shandiswa yakawandisa, uye vamwe vanogadzira vanoshandisa 200,000 yuan kugadzira putty. Iyo putty inogadzirwa nenzira iyi ine viscosity yakakwirira, saka inonyura kana batch scraping. kunzwa kwe. Nhamba yakakurudzirwa yeputty yemadziro emukati ndeye 3-5 kg, uye viscosity ndeye 80,000-100,000.

4. Sei iwe uchinzwa kuti viscosity yehydroxypropyl methylcellulose (HPMC) ine viscosity yakafanana yakasiyana munguva yechando nezhizha?

Nekuda kweiyo thermal gelation yechigadzirwa, viscosity ye putty uye dhaka ichaderera zvishoma nezvishoma nekuwedzera kwekushisa. Kana iyo tembiricha ichipfuura tembiricha yegel yechigadzirwa, chigadzirwa chinonatswa kubva mumvura uye chinorasikirwa nemaviscosity. Tembiricha yekamuri muzhizha kazhinji iri pamusoro pe30 madhigirii, ayo akasiyana zvakanyanya nekupisa munguva yechando, saka viscosity yakaderera. Zvinokurudzirwa kusarudza chigadzirwa chine viscosity yakakwirira paunoshandisa chigadzirwa muzhizha, kana kuwedzera huwandu hwehydroxypropyl methylcellulose (HPMC), uye kusarudza chigadzirwa chine tembiricha yegel.
