Upfu hweputty chinhu chinoshandiswa zvakanyanya pakuvaka, chinoshandiswa zvakanyanya pakuenzana kwemadziro, kuzadza mitswe uye kupa nzvimbo yakatsetseka yekupenda nekushongedza zvinotevera. Cellulose ether chimwe chezvinhu zvakakosha muupfu hweputty, izvo zvinogona kuvandudza mashandiro ekuvaka uye mhando yeupfu hweputty. Chinyorwa chino chichatsanangura zvakadzama mashandisirwo chaiwo e ethers dze cellulose muupfu hweputty uye kukosha kwadzo kuindasitiri yekuvaka.
1. Hunhu hwekutanga uye mashandiro e ethers e cellulose
Cellulose ether rudzi rwepolymer inonyungudika mumvura inowanikwa nekushandiswa kwemakemikari uchishandisa cellulose yechisikigo sechinhu chisina kugadzirwa. Maumbirwo ayo emamorekuru ane huwandu hwakawanda hwemapoka ehydrophilic (akadai sehydroxyl, methoxy, nezvimwewo), izvo zvinoita kuti cellulose ether inyungudike zvakanaka mumvura uye ikwanise kukora. Mukushandisa putty powder, basa guru re cellulose ether rinonyanya kuratidzwa muzvinhu zvinotevera:
Kusimba kwemhedzisiro
Cellulose ether inogona kuwedzera zvakanyanya kunaka kweputty powder slurry, zvichiita kuti ive nethixotropy yakanaka uye kugadzikana, zvichiita kuti kuvaka kuve nyore. Pamusoro pezvo, inogonawo kugadzirisa hunhu hwerheological hweslurry kudzivirira putty powder kuti isayerere kana kutsvedza kubva pamadziro, zvichiita kuti kuvaka kuenderere mberi zvakanaka.
Kuchengetwa kwemvura
Kuchengetwa kwemvura yakawanda kwe cellulose ether ndeimwe yehunhu hwayo hwakakosha kana ikashandiswa muputty powder. Munguva yekuvaka, mushure mekunge putty powder yaiswa pamadziro, kubuda kwemvura kunogona kukonzera kuti putty powder iome uye ibviswe. Cellulose ether inogona kunonoka kurasikirwa nemvura, zvichiita kuti slurry ibudise mvura zvishoma nezvishoma panguva yekuomesa, nokudaro ichivandudza kunamira kweputty, kudzivirira kuoma nekutsemuka, uye kuve nechokwadi chekuti madziro ari kutsvedzerera.
Kuvandudza kugona kushanda
Kuvapo kwe cellulose ether kunovandudza zvikuru mashandiro ekuvaka kweputty powder. Semuenzaniso, zvinogona kuvandudza kuchinjika kweputty, zvichiita kuti zvive nyore kune vashandi vekuvaka kukwesha putty zvakaenzana. Pamusoro pezvo, cellulose ether inogonawo kuderedza kugadzirwa kwemabubbles pamusoro peputty uye kunatsiridza kutsetseka, nokudaro ichivandudza mhedzisiro yekushongedza.
Wedzera maawa ekuvhura
Mukuvaka, nguva yekuvhurwa kweputty powder, kureva kuti, nguva kubva pakushandiswa kusvika pakuomeswa uye kuoma kwechinhu chacho, chinhu chakakosha chinotarisirwa nevashandi vekuvaka. Cellulose ether inogona kuwedzera nguva yekuvhurwa kweputty, kuderedza majoini uye kusaenzana panguva yekuvaka, nokudaro ichivandudza runako rwemadziro.
2. Kushandiswa kwe cellulose ether mumamiriro akasiyana eputty powder
Putty yemadziro yemukati
Mukushandisa putty yemukati memadziro, cellulose ether haingogadzirise kushanda zvakanaka chete, asi inogonawo kugadzirisa kuyerera uye kunamira kweputty kuti ive nechokwadi chekuti pamusoro pemadziro pakanaka uye panobata. Pamusoro pezvo, kushanda kwakanyanya kwe cellulose ether kunogona kudzivirira putty kuti isatsemuke nekuda kwekubuda kwemvura nekukurumidza panguva yekuisa, uye yakakodzera zvinodiwa zvekugara kwenguva refu munzvimbo dzakaoma mukati meimba.
Putty yekunze yemadziro
Putty yekunze yemadziro inofanira kuva nekudzivirira kwakasimba kwemamiriro ekunze uye kudzivirira kupwanyika, nekuti pamusoro pemadziro ekunze pachakanganiswa nemamiriro ekunze, kusiyana kwekupisa nezvimwe zvinhu. Kushandiswa kwe cellulose ether muputty yekunze yemadziro kunogona kuvandudza zvakanyanya kuchengetedza mvura, kudzivirira kupwanyika uye kunamira kwayo, zvichiita kuti ikwanise kuchinja mamiriro ekunze uye kuwedzera hupenyu hwayo hwekushanda. Pamusoro pezvo, cellulose ether inogonawo kubatsira putty kuvandudza kudzivirira kwayo UV, kudzivirira kutonhora nechando nezvimwe zvinhu, kuitira kuti putty yekunze yemadziro irambe ichikwanisa kuchengetedza zvinhu zvayo zvepanyama zvakagadzikana mumamiriro ekunze.
putty isingapindi mvura
Putty isingapindi mvura yakakodzera munzvimbo dzine hunyoro hwakawanda dzakadai sedzimba dzekugezera nekicheni, uye inoda kuti putty isapindi mvura zvakanyanya uye isapindi mvura zvakanyanya. Cellulose ether inogona kuwedzera kushanda kweputty isingapindi mvura zvichibva pakuona kuti inonamira zvakanaka uye inoshanda zvakanaka. Pamusoro pezvo, kukora uye kuchengetedza mvura kwe cellulose ether kunoita kuti putty isingapindi mvura irambe yakagadzikana munzvimbo dzine hunyoro hwakawanda uye kudzivirira matambudziko efungus pamadziro.
Putty yekushongedza yepamusoro-soro
Putty yekushongedza yepamusoro-soro ine zvinodiwa zvakanyanya kuti ive yakatsetseka uye yakapfava, uye inowanzo shandiswa mudzimba dzemhando yepamusoro, mahotera nedzimwe nzvimbo. Cellulose ether inogona kubatsira kunatsa zvidimbu zveputty, kunatsiridza kutsetseka kwepamusoro, kunatsiridza kuchinjika uye kushanda kweputty, kuderedza mabubbles nemaseams, kuita kuti kushongedza kuve kwakakwana, uye kusangana nezvinodiwa zvekushongedza zvenzvimbo dzemhando yepamusoro.
3. Sarudzo yehunyanzvi ye cellulose ether muputty powder
Zvichienderana nezvinodiwa zvekushandisa uye zvinodiwa zvakasiyana zvekushanda kweputty powder, cellulose ethers dzinotevera dzinowanzoshandiswa muindasitiri yekuvaka:
Hydroxypropyl methylcellulose (HPMC)
HPMC chinhu chinoshandiswa zvakanyanya pakuvaka chine simba rekuchengetedza mvura uye kukora. Chinoshandiswa zvakanyanya muzvinhu zvekuvaka zvakaita semadziro emukati nekunze, zvinonamira mataira, uye zvinonamira mapuranga. Chinogona kuvandudza kusimba kwehupfu hweputty uye kushanda zvakanaka, uye chakakodzera zvakanyanya zvinodiwa neputty ine viscosity yakawanda.
Hydroxyethylmethylcellulose (HEMC)
HEMC ine simba rakanaka rekuchengetedza mvura uye kugadzikana, kunyanya munzvimbo dzine tembiricha yakaderera, uye ichiri kugona kuramba ichinyunguduka zvakanaka, saka yakakodzera kushandiswa muputty yekunze yemadziro. Pamusoro pezvo, HEMC ine mhedzisiro yakanaka kwazvo pakuvandudza kupararira uye kufanana kweputty powder, zvichiita kuti pamusoro payo pave panyoro uye panyoro mushure mekuputirwa.
Carboxymethyl cellulose (CMC)
CMC chinhu chinonyungudutsa mvura. Kunyangwe chisina mvura yakawanda uye chisingadonhedze, mutengo wayo wakaderera. Inowanzo shandiswa muupfu hweputty husingadi mvura yakawanda uye hwakakodzera kushandiswa mukati memadziro.
4. Tarisiro nemafambiro e cellulose ethers muindasitiri yeputty powder
Nekufambira mberi kuri kuita indasitiri yekuvaka, zvinodiwa nevanhu zvemhando yepamusoro, kuchengetedzwa kwezvakatipoteredza uye runako rwezvinhu zvekushongedza zvakawedzera zvishoma nezvishoma, uye mikana yekushandisa cellulose ethers yawedzera kukura. Mukufambira mberi kweindasitiri yeputty powder, kushandiswa kwecellulose ether kuchatarisa pane zvinotevera:
Green uye isingakuvadzi nharaunda
Parizvino, zvinhu zvekuvaka zvisingakuvadzi nharaunda inyaya inonyanya kutaurwa muindasitiri yekuvaka. Sezvinhu zvepolymer zvinobva mu cellulose yechisikigo, cellulose ether inoenderana nepfungwa yekudzivirira nharaunda yakasvibirira uye inogona kuderedza kusvibiswa kwekushongedza zvinobudirira. Mune ramangwana, zvigadzirwa zve cellulose ether zvine low-VOC (volatile organic compounds) uye zvigadzirwa zve cellulose ether zvinoshanda zvakanyanya zvichagadzirwa uye zvichashandiswa.
Inoshanda uye yakangwara
Kuvandudzwa kunogara kuripo kwe cellulose ether kunoita kuti putty powder irambe ichishanda zvakanaka munzvimbo dzakaoma. Semuenzaniso, kuburikidza nekugadzirisa magadzirirwo emamorekuru uye kuwedzera zvimwe zvinowedzera, putty powder ine hunhu hwakasimba hwekuchinjika uye hwekuzvirapa, zvichiita kuti zvinhu zvekuvaka zvive zvakangwara uye zvinobudirira.
Kuchinja-chinja
Kunyange zvazvo zvichivandudza hunhu hweputty powder, cellulose ethers inogonawo kuita kuti putty powder ive nemamwe mabasa akadai semaantibacterial, anti-mildew, uye anti-UV kuti ikwanise kushandiswa zvakanyanya.
Kushandiswa kwe cellulose ether mu putty powder hakungogadzirisi mashandiro ekuvaka uye kugara kwenguva refu kwe putty powder chete, asiwo kunovandudza zvikuru mhedzisiro yekushongedza madziro, zvichizadzisa zvinodiwa zvekuvaka kwemazuva ano kuti madziro ave akati sandara, atsvedzerere uye agare kwenguva refu. Nekufambira mberi kuri kuita indasitiri yekuvaka, kushandiswa kwe cellulose ethers mu putty powder kuchawedzera kukura, zvichisundidzira zvinhu zvekushongedza zvivakwa kuti zvishande zvakanaka uye zvidzivirire nharaunda.
