1 Matambudziko Akajairika muWall Putty poda:
(1) Dries nekukurumidza.
Izvi zvinonyanya kuitika nekuti huwandu hweshari calcium poda yakawedzera (huwandu hweshombo yechigadzirwa chinoshandiswa mune yakaderedzwa) inoenderana nehuwandu hwemvura, uye zvinoenderana nekuoma kwemadziro.
(2) peel uye roll.
Izvi zvinoenderana nemvura yekuchengetedza mvura, iyo iri nyore kuitika apo viscosity ye cellulose yakaderera kana huwandu hwekuwedzera idiki.
(3) De-podaing yemukati yemadziro putty poda.
Izvi zvine chekuita nehuwandu hweshitum poda yakawedzera (huwandu hweshari yechiPoula hupfumi hwakanyanya kuwanda, uye huwandu hwechigadzirwa chepfu poda focty Iko kune hukama pakati pehuwandu uye mhando, iyo inoratidzwa mumuyero wekuchengetwa kwemvura yechigadzirwa. Rwiyo rwekuchengetwa kwemvura yakaderera, uye iyo ash calcium poda
(4) kupokana.
Izvi zvine chekuita neyakaoma humidity uye kubata kumeso kwemadziro, uye zvakare zvine chekuita nekuvakwa.
(5) manhamba anoonekwa.
Izvi zvinoenderana ne cellulose, iyo ine isina kunaka firimu-inoumba zvivakwa. Panguva imwecheteyo, kusachena mu cellulose kunoita zvishoma neAsh calcium. Kana maitiro akanyanya, iyo putty poda ichaonekwa mumamiriro eBhinzi curd yakasara. Haigoni kuiswa pamadziro, uye haina simba rekubatana panguva imwe chete. Uye zvakare, iyi mamiriro ezvinhu anoitika nezvigadzirwa zvakadai se carboxyl mapoka akawedzera kune cellulose.
(6) mahombekombe edenga nemipimi anoonekwa.
Izvi zviri pachena zvine chekuita nemvura yekuona kwemvura yeiyo hydroxyprupropropyl methylcellose mhinduro. Iyo tensi yemvura tension yeiyo hydroxytlyl mhinduro mhinduro haina pachena. Zvingave zvakanaka kuita kurapwa kwekupedza.
(7) mushure mekufa kwemvura, zviri nyore kupaza uye kutendeuka yero.
Izvi zvinoenderana nekuwedzera kwehuwandu hukuru hweash-calcium poda. Kana iyo huwandu hwesh-calcium poda inowedzerwa zvakanyanya, kuomarara kweiyo putty poda inowedzera mushure mekuoma. Kana iyo poro poda isina kuchinjika, ichapwanya nyore, kunyanya kana ichiiswa pasi peimba yekunze. Izvo zvakare zvine chekuita nezvirimo zvakakwirira zve calcium oxide mune ash calcium poda, iyo yakaunzwa pakutanga.
2 Nei iyo perod poda ichinge yakatetepa mushure mekuwedzera mvura?
Cellulose inoshandiswa seyakakoshwa uye yemvura-inochengetedza mumiririri mune putty. Nekuda kweiyo thkixotropy ye cellulose pachayo, kuwedzera kwemasero mune iyo putty poda zvakare inotungamira kune iyo thisiotropy mushure mekuwedzera mvura kune iyo putty. Iyi thiskotropy inokonzerwa nekuparadzwa kwechimiro chakasarudzika chezvikamu mune iyo putty poda. Ichi chimiro chinomuka pakuzorora uye kupwanya pasi pekushushikana. Izvi zvinoreva kuti, viscosity inoderera pasi pekusimudzira, uye visikoka vanodzora kana vamire.
3 Nei iyo putty iri kuremerwa mukukanda maitiro?
Mune ino kesi, iyo visikopo yemheremello kazhinji inoshandiswa yakanyanya. Vamwe vagadziri vanoshandisa 200,000 Cellulose kuti vatadze. Iyo putty yakaburitswa nenzira iyi ine viscossity yakakwirira, saka inonzwa kurema kana ichipenya. Iyo yakakurudzirwa huwandu hwekutyisa kwemadziro emukati ndeye 3-5 kg, uye zvikwangwani mazana masere ezviuru.
4 Nei iyo putty uye yakagadzirwa nemutero neiyo cellulose neiyo viscosity siga yanzwa yakasiyana munguva yechando uye zhizha?
Nekuda kweiyo iyo inopisa gelation yechigadzirwa, iyo viscosity yechigadzirwa ichadzikira zvishoma nezvishoma nekuwedzera kwekushisa. Kana tembiricha ichidarika iyo tembiricha yechigadzirwa, chigadzirwa chichava chakaratidzwa kubva mumvura uye kurasikirwa zvavakaita. Iyo tembiricha yemakamuri muzhizha inowanzoita pamusoro pemakumi matatu emadhigirii, izvo zvakasiyana zvakanyanya kubva pakupisa munguva yechando, saka viscosity yakaderera. Inokurudzirwa kusarudza chigadzirwa neyekumusoro viscosity kana uchishandisa chigadzirwa muzhizha, kana kuwedzera huwandu hwemasoulose, uye kusarudza chigadzirwa neyakakwira tembiricha. Edza kusashandisa methyl cellelose muzhizha, jecha tembiricha iri kutenderera 55, kana tembiricha ichikwira zvishoma, viscosity yayo ichakanganiswa zvikuru.
