omesa nekukurumidza
Izvi zvinonyanya kukonzerwa nekuwedzera kwekuwedzera kweash calcium powder (yakawanda yeash calcium powder inoshandiswa muputty formula inogona kuderedzwa zvakakodzera) inobatana nehuwandu hwekuchengetedza mvura yehydroxypropyl methylcellulose, uye inobatanidzawo nekuoma kwemadziro. .
Peeling uye kukunguruka
Izvi zvinoenderana nehuwandu hwehuwandu hweash calcium kana iyo yakaderera mvura yekuchengetedza chiyero chehydroxypropyl methylcellulose, iyo inowanzoitika kana viscosity ye cellulose yakaderera kana iyo yekuwedzera mari idiki.
De-upfu hwemukati wemadziro putty poda
Izvi zvinoenderana nehuwandu hweash calcium powder yakawedzerwa (huwandu hweash calcium powder muputty formula iduku zvikuru kana kuchena kweash calcium powder yakanyanya kuderera, uye uwandu hwehupfu hwekasium muputty powder formula inofanira. kuwedzerwa zvakakodzera), uye inobatanidzawo nekuwedzerwa kwe cellulose Pane hukama pakati pehuwandu uye hutano, hunoratidzwa muhuwandu hwekuchengetedza mvura kwechigadzirwa. Mvura yekuchengetedza mvura yakaderera, uye nguva yekuita yeash calcium powder (iyo calcium oxide mumadota eupfu haisati yashandurwa zvakakwana ku calcium hydroxide) haina kukwana, iyo inokonzerwa.
kutubukira
Izvi zvine hukama nehunyoro hwakaoma uye flatness yemadziro, uye zvakare inoenderana nekuvakwa.
pin point
Izvi zvakabatana ne cellulose, iyo ine urombo hwekugadzira firimu. Panguva imwecheteyo, kusvibiswa mu cellulose kunobata zvishoma neash calcium. Kana maitiro acho akaoma, iyo putty powder ichaonekwa mumamiriro ebhinzi curd yakasara. Haikwanise kuiswa pamadziro, uye haina simba rakabatana panguva imwe chete. Mukuwedzera, mamiriro ezvinhu aya anoitikawo nemishonga yakadai se carboxymethyl yakasanganiswa ne cellulose.
Makomo anoputika nemapinho anooneka
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. Izvo zvakare zvine chekuita nekuwedzera kwekuwedzera kwehydroxypropyl methylcellulose.
Mushure mekunge putty yaoma, zviri nyore kuputika uye kushanduka yero
Izvi zvakabatana nekuwedzera kwehuwandu hweash-calcium powder. Kana iyo yakawanda ye-ash-calcium powder inowedzera zvakanyanya, kuoma kweputty powder kuchawedzera mushure mekuoma. Kana iyo putty powder isina kushanduka, inoputika nyore nyore, kunyanya kana ichiiswa pasi pesimba rekunze. Iyo inobatanawo nehuwandu hwehuwandu hwe calcium oxide mu ash calcium powder.
Sei iyo putty poda ichive yakaonda mushure mekuwedzera mvura?
Cellulose inoshandiswa seyakakora uye inochengetedza mvura mumiriri pa putty. 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 viscosity ye cellulose inonzwa yakasiyana kana uchishandisa imwechete viscosity cellulose 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 hweselulosi, uye kusarudza chigadzirwa chine tembiricha yepamusoro yegel.
