Cellulose ana vana kirasi yeakakwira mamexalar uremu-soluble polymers dzakatorwa kubva ku cellulose. Ivo vakave vachishandiswa zvakanyanya muindasitiri yekuvaka seyakaitwa-nekuvandudza admixture yeiyo coment-yakavakirwa uye yeGypsum zvigadzirwa. Pakati pavo, hydroxyprupyl methylcellose (HPMC) ndeimwe yeanonyanya kukosha cellulose ana avaneta.
Semugadziri wenyanzvi Hpmc, isu tichakutsanangurira basa remheremelle ether mune putty. Isu tinovimba iyi posvo inopa dzimwe nzwisiso dzinobatsira kune avo vanofarira iyi nyaya.
1. Kuchengeta mvura
Imwe yemabasa makuru e cellulose ether ye putty ndeyekuchengeta kwemvura. Putty is a paste-yakaita zvinhu zvinoshandiswa kuzadza mapundu uye marara munzvimbo dzakadai semadziro, maruva uye pasi. Mvura yakakosha mune zvekupfeka zvakarongeka nekuti zvinobatsira kunyungudutsira zvinwiwa uye zvinopa basa rekushanda. Nekudaro, mvura yakawandisa inogona kukonzera iyo putty kuoma uye ichidzora nekukurumidza, inotungamira kupaza uye kupedzisa-kuderera kwemhando.
Cellulose Ether, kunyanya HPMC, inoumba chimiro cheGE-senge chakasanganiswa nemvura, izvo zvinogona kuvandudza kuchengetwa kwemvura kwekuchengetwa kwemvura. Iwo mapoka ehydrophilic eHPMC anogona kutora mamorekuru emvura uye kudzivirira kubva mukubuda nekukurumidza. Iyi ficha inobvumira kwenguva refu yekushanda uye yakanyanya kuwirirana putty.
2. Kuvandudza Kushanda
Rimwe basa rakakosha re cellulose ether for putty ndeyekuvandudza basa rayo. Kurovedza kunoreva kusunungurwa uko iyo iyo putty yaiswa uye yakaumbwa kuti uwane nzvimbo yakatsiga. Cellulose ether inogona kuwedzera iyo fluidity uye kupararira kwekutyisa nekudzora kupokana pakati pezvikamu uye kuwedzera lubrication yehurongwa.
Kuwedzera kweinterin cellulose ana vana kune zvinowanzo kuderedza zvakare mhepo yekukonzerwa nekuvhengana, iyo inogona kutungamira kunzvimbo isina kufanana uye kushamwaridzana kusarongeka. Iko kushandiswa kwe cellulose etana kunovandudza kusimba uye kusawirirana kweiyo putty, zvichikonzera kuita kwakazara kwekuita uye kupedzisa kunonaka.
3. Kuwedzera Dhiziri
Rimwe betsero yemasero ether kuti putty inowedzerwa kudenha. Mari inoshandiswa kuzadza mapundu uye marara, pamwe nekugadzira nzvimbo yakatsiga yekupenda kana kumwe kupedzisa. Naizvozvo, iyo putty inofanira kukwanisa kuomerera kune substrate uye kupa chisungo chakasimba.
Cellulose ether, kunyanya hpmc, inogona kuvandudza kudenha kwekutyisa nekuumba firimu pamusoro peiyo substrate. Iyo firimu inosimudzira kusangana pakati peiyo putty uye substrate uye inobatsira kuzadza mamiriro ezvinhu zvisina kujairika. Izvi zvinoguma neushamwari hwakasimba uye kupedzwa kwakanyanya.
4. Kuderedza shrinkage
Shrinkage idambudziko rakajairika nePutty, sezvazvinogona kutungamira pakupaza uye kupedzisira kushoma. Cellulose etana inogona kubatsira kuderedza putty shrinkage nekuvandudza kuchengetwa kwemvura uye kushanda kweiyo putty. Mvura inobhururuka zvishoma zvishoma, ichipa petty ainyanya kugadzirwa iyo inobatsira kudzivirira marara uye maCluketi kubva pakugadzira panguva yekuomesa.
Mukuwedzera, cellulose ether inogona zvakare kudzikisa kupurasitiki kuderera kweiyo putty, ndiko kuti, kuderera kunoitika panguva yekutanga kurongeka. Ichi chivakwa chinonyanya kukosha pakuisa zvinokurumidza putties, sezvo zvichibatsira chengetedza kutendeka kwemukati uye kudzivirira kuumbwa kwemaza.
5. Kuvandudzwa kuimba
Pakupedzisira, cellaulose etana vanogona kuvandudza kusimba kwekutyisa nekuvandudza kupokana kwaro kune zvinhu zvakatipoteredza zvinhu zvakadai sekusimbirira kushanduka, humreity uye abrasion. Iyo firimu-inogadzira zvivakwa zve cellulose ether inogona kupa chipinganidzo chekudzivirira pane iyo platy pamusoro yekudzivirira kupindira kwemvura uye kumwe kusvibiswa.
Zvakare, Cellulose ether zvinogonawo kuvandudza simba rinoslippura uye kukanganisa kuramba kweiyo putty, kuiita kuti iite kuramba kupaza uye chipplat. Iyi pfuma inonyanya kukosha kune mafambiro emahara anowanzoitwa kana kukanganiswa, sekushanda kwebasa rekugadzira kana rekushongedza kupedzisa.
mumhedziso
Mukupedzisa, mheremalose etiers, kunyanya hpmc, zvakakosha putty putty kuita kunowedzera kufungidzira. Mabasa avo anosanganisira kuchengetwa kwemvura, kugadzirisa kwakavandudzwa, kwakawedzera kudenha, kuderedzwa kuderera uye kuvandudzwa kusimba. Uchishandisa cellulose anaiters inobatsira kuvandudza hunhu hwese uye kuita kwekutyisa, zvichikonzera kupedzisa kuri nani uye hupenyu hurefu. Semunhu anogadzira HPMC mugadziri, isu takazvipira kupa vatengi vane yakakwira-mhando cellulose ether uye technical rutsigiro.
