Putty ufa ndi chinthu chomangira chomwe chimagwiritsidwa ntchito kwambiri, chomwe chimagwiritsidwa ntchito kwambiri kukweza khoma, kudzaza ming'alu ndikupereka malo osalala kuti apente ndi kukongoletsa. Cellulose ether ndi imodzi mwazowonjezera zofunika mu putty powder, zomwe zingathe kupititsa patsogolo ntchito yomanga ndi khalidwe la putty powder. Nkhaniyi ifotokoza mwatsatanetsatane kagwiritsidwe ntchito ka cellulose ethers mu putty powder komanso kufunika kwake pantchito yomanga.
1. Zinthu zoyambira ndi ntchito zama cellulose ethers
Cellulose ether ndi mtundu wa polima wosungunuka m'madzi womwe umapezeka posintha mankhwala pogwiritsa ntchito mapadi achilengedwe ngati zinthu zopangira. Mapangidwe ake a maselo ali ndi magulu ambiri a hydrophilic (monga hydroxyl, methoxy, etc.), omwe amapereka cellulose ether kusungunuka kwamadzi abwino komanso kukulitsa mphamvu. Pogwiritsira ntchito putty powder, gawo lalikulu la cellulose ether limawonekera makamaka m'magawo awa:
Makulidwe zotsatira
Ma cellulose ether amatha kuwonjezera kukhuthala kwa putty powder slurry, kupangitsa kuti ikhale ndi thixotropy wabwino komanso kukhazikika, motero kumathandizira yomanga. Kuphatikiza apo, imathanso kusintha mawonekedwe a rheological a slurry kuti ateteze ufa wa putty kuti usasunthike kapena kutsetsereka pakhoma, kuonetsetsa kuti zomangamanga zikuyenda bwino.
Kusunga madzi
Kusungidwa kwamadzi kwapamwamba kwa cellulose ether ndi chimodzi mwazofunikira zake zikagwiritsidwa ntchito mu putty powder. Panthawi yomanga, ufa wa putty utayikidwa pakhoma, kutuluka kwa madzi kumapangitsa kuti ufa wa putty uume ndi peel. Ma cellulose ether amatha kuchedwetsa kutayika kwa madzi, kupangitsa kuti slurry atulutse madzi pang'onopang'ono panthawi yowumitsa, motero amawongolera kumamatira kwa putty, kupewa kuyanika ndi kusweka, ndikuwonetsetsa kuti khomalo likuyenda bwino.
Limbikitsani magwiridwe antchito
Kukhalapo kwa cellulose ether kumathandizira kwambiri ntchito yomanga ya putty powder. Mwachitsanzo, imatha kusintha kusinthasintha kwa putty, kupangitsa kukhala kosavuta kwa ogwira ntchito yomanga kukwapula putty mofanana. Kuphatikiza apo, ether ya cellulose imathanso kuchepetsa kutulutsa kwa thovu pamtunda wa putty ndikuwongolera kusalala, motero kumapangitsa kukongoletsa.
Wonjezerani maola otsegulira
Pomanga, nthawi yotsegulira ufa wa putty, ndiko kuti, nthawi yochokera ku ntchito mpaka kuyanika ndi kulimbitsa zinthu, ndizofunikira kwambiri zomwe ogwira ntchito yomanga amamvetsera. Cellulose ether imatha kukulitsa nthawi yotsegulira ya putty, kuchepetsa zolumikizana ndi kusagwirizana pakumanga, potero kuwongolera kukongola kwa khoma.
2. Kugwiritsa ntchito cellulose ether muzochitika zosiyanasiyana za putty powder
Interior wall putty
Mu ntchito mkati khoma putty, mapadi efa osati bwino workability, komanso kusintha fluidity ndi adhesion wa putty kuonetsetsa yosalala ndi adhesion wa pamwamba khoma. Kuonjezera apo, kusungirako madzi kwapamwamba kwa cellulose ether kungalepheretse putty kusweka chifukwa cha kutuluka kwamadzi mofulumira panthawi yogwiritsira ntchito, ndipo ndi yoyenera kwa nthawi yayitali yokhazikika m'malo owuma amkati.
Kunja kwa khoma putty
Kunja kwa khoma putty kumafunika kukhala ndi mphamvu yolimbana ndi nyengo komanso kukana ming'alu, chifukwa pamwamba pa khoma lakunja lidzakhudzidwa ndi nyengo, kusiyana kwa kutentha ndi zina. Kugwiritsidwa ntchito kwa cellulose ether kunja kwa khoma putty kumatha kusintha kwambiri kusungidwa kwa madzi, kukana ming'alu ndi kumamatira, kulola kuti igwirizane ndi kusintha kwa chilengedwe chakunja ndikuwonjezera moyo wake wautumiki. Kuphatikiza apo, ether ya cellulose ingathandizenso putty kuwongolera kukana kwa UV, kukana kuzizira ndi zinthu zina, kotero kuti kunja kwa khoma la putty kumatha kukhalabe ndi zinthu zokhazikika panja.
putty yopanda madzi
Putty yopanda madzi ndi yoyenera malo okhala ndi chinyezi chambiri monga mabafa ndi makhitchini, ndipo imafunikira kutetezedwa kwamadzi komanso kukana madzi kwa putty. Ma cellulose ether amatha kupititsa patsogolo magwiridwe antchito osalowa madzi a putty poonetsetsa kuti amamatira komanso kugwira ntchito kwake. Kuonjezera apo, kukhuthala ndi kusunga madzi kwa cellulose ether kumathandiza kuti madzi asalowe m'madzi kuti azikhala okhazikika m'madera omwe ali ndi chinyezi chambiri komanso kupewa mavuto a mildew pamakoma.
Putty yokongoletsera yapamwamba
Putty yokongoletsera yapamwamba imakhala ndi zofunikira kwambiri za flatness ndi fineness, ndipo nthawi zambiri zimagwiritsidwa ntchito m'nyumba zapamwamba, mahotela ndi malo ena. Ma cellulose ether angathandize kuyeretsa tinthu tating'onoting'ono ta putty, kukonza kusalala kwa pamwamba, kusintha kusinthasintha ndi kugwirira ntchito kwa putty, kuchepetsa thovu ndi seams, kupanga chokongoletsera kukhala changwiro, ndikukwaniritsa zosowa za malo apamwamba.
3. Kusankhidwa kwaukadaulo kwa cellulose ether mu putty powder
Malinga ndi zosowa zogwiritsira ntchito komanso zofunikira zosiyanasiyana za ufa wa putty, ma ether a cellulose otsatirawa amagwiritsidwa ntchito nthawi zambiri pantchito yomanga:
Hydroxypropyl methylcellulose (HPMC)
HPMC ndi chowonjezera chomanga chomwe chimagwiritsidwa ntchito kwambiri chokhala ndi madzi osungira komanso kukhuthala. Amagwiritsidwa ntchito kwambiri muzomangira monga mkati ndi kunja kwa khoma putty, zomatira matailosi, ndi pulasitala matope. Ikhoza kupititsa patsogolo kukana kwa sag ndi kugwira ntchito kwa ufa wa putty, ndipo ndizofunikira makamaka pazosowa za high-viscosity putty.
Hydroxyethylmethylcellulose (HEMC)
HEMC ili ndi ntchito yabwino yosungira madzi komanso kukhazikika, makamaka m'malo otentha kwambiri, ndipo imatha kukhalabe yosungunuka bwino, kotero ndiyoyenera kugwiritsidwa ntchito kunja kwa khoma la putty. Kuphatikiza apo, HEMC imakhala ndi zotsatira zabwino kwambiri pakuwongolera kubalalitsidwa ndi kufanana kwa ufa wa putty, kupangitsa kuti pamwamba pakhale bwino komanso bwino pambuyo pakupaka.
Carboxymethyl cellulose (CMC)
CMC ndi chokhuthala chosungunuka m'madzi. Ngakhale ili ndi kusungirako madzi otsika komanso anti-sag katundu, mtengo wake ndi wotsika. Nthawi zambiri amagwiritsidwa ntchito mu putty powder omwe safuna kusungirako madzi ambiri ndipo ndi oyenera kuyika mkati mwa khoma la putty.
4. Chiyembekezo ndi machitidwe a cellulose ethers mu putty powder industry
Ndi chitukuko chosalekeza cha makampani omangamanga, zofunikira za anthu za khalidwe, chitetezo cha chilengedwe ndi kukongola kwa zipangizo zokongoletsa zawonjezeka pang'onopang'ono, ndipo chiyembekezo chogwiritsira ntchito ma cellulose ethers chakula kwambiri. Pachitukuko chamtsogolo chamakampani a putty powder, kugwiritsa ntchito cellulose ether kudzayang'ana pa izi:
Zobiriwira komanso zachilengedwe
Pakali pano, zipangizo zomangira zachilengedwe ndizofunika kwambiri pa ntchito yomanga. Monga zinthu za polima zomwe zimachokera ku cellulose yachilengedwe, ether ya cellulose imagwirizana ndi lingaliro lachitetezo cha chilengedwe chobiriwira ndipo imatha kuchepetsa kuipitsidwa kwa zokongoletsera. M'tsogolomu, zinthu zotsika kwambiri za VOC (zosakanikirana zamagulu achilengedwe) ndi mankhwala a cellulose ether apamwamba kwambiri adzapangidwa ndikugwiritsidwa ntchito.
Kuchita bwino komanso mwanzeru
Kusintha kosalekeza kwa cellulose ether kumathandizira ufa wa putty kukhalabe wokhazikika m'malo ovuta. Mwachitsanzo, kudzera mu kukhathamiritsa kwa mamolekyu ndi kuwonjezera zowonjezera, ufa wa putty umakhala ndi mphamvu zosinthika komanso zodzichiritsa zokha, zomwe zimapangitsa kuti zida zomangira zikhale zanzeru komanso zogwira mtima.
Kusinthasintha
Ngakhale kukonza zinthu zofunika za ufa wa putty, ma cellulose ethers amathanso kupanga ufa wa putty kukhala ndi ntchito zina monga antibacterial, anti-mildew, ndi anti-UV kuti akwaniritse zosowa za zochitika zapadera kwambiri.
Kugwiritsiridwa ntchito kwa cellulose ether mu putty powder sikungowonjezera ntchito yomanga ndi kukhazikika kwa ufa wa putty, komanso kumapangitsanso kwambiri zotsatira za kukongoletsa khoma, kukwaniritsa zofunikira za zomangamanga zamakono za khoma la flatness, kusalala komanso kukhazikika. . Ndi chitukuko chosalekeza chamakampani omanga, kugwiritsa ntchito ma cellulose ethers mu putty powder kudzachulukirachulukira, ndikukankhira zida zokongoletsera zomangira kuti zigwire ntchito kwambiri komanso kuteteza chilengedwe.
