Mhedzisiro yeCellulose Ether muPutty Powder Application

Ndechipi chikonzero chekuti putty powder iome nekukurumidza?

Izvi zvinonyanya kuenderana nekuwedzera kweash calcium uye chiyero chekuchengetedza mvura yefiber, uye zvakare yakabatana nekuoma kwemadziro.

Zvakadini nekupepeta nekuumburudza?

Izvi zvakabatana nehuwandu hwekuchengetedza mvura, izvo zviri nyore kuitika kana viscosity ye cellulose yakaderera kana kuwanda kwekuwedzera kuduku.

Pane dzimwe nguva ine zvinonongedza here?

Izvi zvakabatana ne cellulose, iyo ine urombo husina kunaka hwekugadzira firimu, uye panguva imwe chete, tsvina mu cellulose inobata zvishoma ne ash calcium. Kana kuita kwakanyanya, putty powder ichaita senge bhinzi yakasara. Haikwanise kuiswa pamadziro, uye haina simba rakabatana panguva imwe chete. Mukuwedzera, mamiriro aya anoitikawo nezvigadzirwa zvakaita semapoka e-carboxyl akawedzerwa kune cellulose.

Makomo anoputika nemapinho?

Izvi zviripachena zvine chekuita nekunetsana kwemvura pamusoro peiyo hydroxypropyl methylcellulose aqueous solution. Iko kushushikana kwemvura patafura yehydroxyethyl aqueous solution haisi pachena. Zvingava zvakanaka kuita finishing treatment.

Sei iyo putty poda ichive yakaonda mushure mekuwedzera mvura?

Cellulose inoshandiswa seyakakora uye inochengetedza mvura mumiriri. Pamusana pe thixotropy ye cellulose pachayo, kuwedzerwa kwe cellulose mu putty powder kunotungamirirawo kuthixotropy 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.

Ndechipi chikonzero nei putty iri kurema mukukwesha?

Muchiitiko ichi, viscosity ye cellulose inowanzoshandiswa yakanyanyisa. Vamwe vagadziri vanoshandisa 200,000 cellulose kugadzira putty. Iyo putty inogadzirwa nenzira iyi ine viscosity yakakwirira, saka inonzwa inorema kana ichikwesha. Nhamba yakakurudzirwa yeputty yemadziro emukati ndeye 3-5 kg, uye viscosity ndeye 80,000-100,000.

Sei iyo putty uye dhaka yakagadzirwa ne cellulose ine viscosity yakafanana inonzwa zvakasiyana muchando uye zhizha?

Nekuda kweiyo thermal gelation yechigadzirwa, viscosity yechigadzirwa 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 zvigadzirwa zvine tembiricha yegel kana uchiisa zvigadzirwa muzhizha. Iyo tembiricha yegel yechigadzirwa kazhinji iri pamusoro pe75 degrees. Wall putty yenyika chiyero (JG/T298-2009) zvakajairwa zvinodiwa, mhando yechigadzirwa yakagadzikana, zero voc kuita kwemamiriro ekunze kwakanaka. Kazhinji, tembiricha yegel yemethyl cellulose ingangoita 55 degrees muzhizha. Kana tembiricha yakakwira zvishoma, viscosity yayo ichakanganiswa zvakanyanya.
