Phukusi la putty ndi malo opangira nyumba, makamaka amagwiritsidwa ntchito pamakoma, ndikudzaza ming'alu ndikupereka malo osalala popaka utoto ndi zokongoletsera. Cellulose ether ndi imodzi mwazowonjezera zowonjezera mu ufa wa punty ufa, womwe umatha kusintha kwambiri magwiridwe antchito ndi mtundu wa putty ufa. Nkhaniyi ifotokoza mwatsatanetsatane kugwiritsa ntchito kwa cellulose kukhala ndi ufa wa putty ndi kufunikira kwake kumalo omanga.
1. Zoyambira zoyambira ndi ntchito za cellulose et
Cellulose ether ndi mtundu wamadzi osungunuka polymer omwe adakhazikitsidwa ndi kusintha kwa mankhwala pogwiritsa ntchito cellulose yachilengedwe ngati zipatso. Kapangidwe kake kake kamakhala ndi magulu ambiri a hydrophilic (monga hydroxyl, methoxy, etc.), zomwe zimapatsa cellulose ethebility madzi soller ndi kukula. Pogwiritsa ntchito ufa wa putty, udindo waukulu wa ether ether umawonetsedwa m'zinthu zotsatirazi:
Kukula
Cellulose ether imatha kuwonjezera mawilo a putty ufa wosalala, ndikupangitsa kukhala ndi thixotropy ndi bata, motero ochita kumanga. Kuphatikiza apo, imasinthanso za slurry ya slurry kuti muchepetse ufa wotuluka kapena wotsika kukhoma, ndikuonetsetsa kuti ntchito yomanga isayendetsedwe.
Kusungidwa kwamadzi
Kusunga kwamadzi kwakukulu kwa ethel ether ndi imodzi mwamakhalidwe ake ofunikira mukamagwiritsa ntchito ufa. Panthawi yomanga, ufa wa punty utagwiritsidwa ntchito kukhoma, madzi osinthika amatha kupangitsa kuti ufa uwu uwume ndi kusenda. Cellulose ether imatha kuchedwetsa madzi, ndikupangitsa kuti malo odulirawo asamasule madzi pang'onopang'ono panthawi yowuma, motero kumasinthiratu kukhala kouma, kupewa kuyanika ndi kuwonongeka, ndikuwonetsetsa kuti pakhoma.
Sinthani Kuthana
Kukhalapo kwa cellulose ether kumathandiza kwambiri kumayendedwe a putty ufa. Mwachitsanzo, zitha kusintha kusinthasintha, ndikupangitsa kuti ogwira ntchito omanga atuluke kwambiri. Kuphatikiza apo, cellulose ether imathanso kuchepetsa m'badwo wa thovu pamtunda wa pulity ndikusintha, motero kukonza zokongoletsera.
Kuwonjezera maola otseguka
Pomanga, nthawi yotseguka ya ufa wa putty, ndiye kuti, nthawi yogwirira ntchito ndi kukhazikika kwa zinthuzo, ndi gawo lofunikira lomwe anthu omanga amasamala. Cellulose ether ikhoza kukulitsa nthawi yotseguka, kuchepetsa mafupa komanso mosagwirizana pomanga, potero kukonza zokopa za khoma.
2. Kugwiritsa ntchito cellulose ether mu mawonekedwe osiyanasiyana a putty ufa
Khoma lamkati
Pogwiritsa ntchito khoma lamkati lamkati, cellulose sikuti limangosintha madziwo, komanso amathanso kusintha madziwo ndi kutsatsa madzi kuti awonetsetse kuti asasunthe kusalala ndi kutsatira khoma. Kuphatikiza apo, kusunga madzi ambiri magwiridwe antchito a cellulose kungalepheretse kuwonongeka chifukwa cha madzi osinthika mwachangu panthawi yofunsira, ndipo ndioyenera njira zokhazikika m'malo owuma.
Khoma lakunja
Dera lakunja likufunika kukana ndi kuchuluka kwanyengo yolimba komanso kusokonekera kwa khoma lakunja lidzakhudzidwa ndi nyengo, kusiyana kwa kutentha ndi zinthu zina. Kugwiritsa ntchito cellulose etherti oyambira kunja kumatha kusintha madzi ake mosamala, kukana kwa chilengedwe ndi kutsatira, kuloleza kuti izisintha moyo wake. Kuphatikiza apo, cellulose ether ingathandizenso kukonza magwiridwe ake a UV.
Madzi ofunda
Madzi ofunda ndi abwino kwambiri okhala ndi chinyezi monga mabafa ndi makhitchini, ndipo amafuna madzi osamba kwambiri ndi madzi osokoneza. Cellulose ether imatha kukulitsa magwiridwe ake a pangani chifukwa chowonetsetsa kuti azitsatira komanso kugwirira ntchito. Kuphatikiza apo, zotsatirapo zopitilira muyeso za cellulose ether zimathandizira kukhazikika kwa madzi kukhalabe okhazikika m'malo okhala ndi chinyezi chachikulu ndikupewa mavuto a mitsempha.
Kukongoletsa Kwambiri
Mafuta okongoletsa kwambiri ali ndi zofunikira kwambiri pakusalala komanso bwino, ndipo nthawi zambiri kumagwiritsidwa ntchito pokhala m'mapiri, hotelo ndi malo ena. Cellulose ether angathandize kukonza tinthu tating'onoting'ono, kusintha kosasunthika, kukonza kusinthasintha kwamphamvu, kumachepetsa thovu ndi seams, kupanga zokongoletsera zake m'malo otentha kwambiri.
3. Kusankhidwa kwaukadaulo kwa cellulose ether mu ufa
Malinga ndi zofunikira za pulogalamuyo ndi zofunikira zosiyanasiyana za putty ufa, cellulose yotsatirayi imagwiritsidwa ntchito pomanga:
Hydroxypropyl methylcellulose (hpmc)
HPMC ndi yowonjezera yomanga yomanga ndi kusungidwa kwabwino kwamadzi komanso kukula kwa kukula. Amagwiritsidwa ntchito kwambiri popanga zinthu zomanga monga mkati ndi kunja, zomata za matabwa, komanso matope oyala. Itha kukonza kukana kwa sathag ndi kugwirira ufa wa putty, ndipo ndizoyenera makamaka pakufunikira kwa mafayilo apamwamba.
Hydroxyethymethylcellulose (hemc)
Hemc ali ndi magwiridwe antchito abwino kwambiri komanso kukhazikika, makamaka pamasamba ochepa, ndipo amatha kukhalabe osungunuka bwino, motero ndi koyenera kugwiritsa ntchito khoma lakunja. Kuphatikiza apo, hemc imakhala ndi zotsatira zabwino kwambiri kukonza kufalikira ndi kufanana kwa ufa wa putty, ndikupangitsa pansi pansi komanso kusanja.
Carboxymethyl cellulose (cmc)
Cmc ndi wosungunuka wamadzi. Ngakhale ili ndi madzi osungira madzi otsika komanso katundu wa sag-sag, mtengo wake ndi wotsika. Nthawi zambiri imagwiritsidwa ntchito mu ufa wa putty yemwe safuna kusungidwa kwamadzi kwambiri ndipo ndi yoyenera kugwiritsidwa ntchito kwa mkati.
4. Ziyembekezero ndi zotengera za cellulose
Ndi chitukuko chopitilira pa zomangamanga, zomwe anthu amafuna kwa mtunduwo, kutetezedwa kwa chilengedwe ndi zokondweretsa zomwe zimapangidwa pang'onopang'ono kwatichulukira, ndipo zopewera ntchito ya cellulose itakula. Munthawi yonseyi kuchitika kwa ma pulani a ptty ufa, kugwiritsa ntchito ethel ether ether kumangoyang'ana mbali zotsatirazi:
Wobiriwira komanso wachilengedwe
Pakadali pano, zomangira zomanga zachilengedwe ndi nkhani yotentha m'malo omanga. Monga chuma cha polymer kuchokera ku cellulose ya chilengedwe, cellulose ether gwiritsiridwa ndi lingaliro la kutetezedwa kwa chilengedwe chobiriwira ndipo amatha kupulumutsa kuwonongeka kwa zokongoletsera. M'tsogolo, otsika kwambiri otsika (osasunthika okhazikika) ndi zinthu zolimbitsa thupi kwambiri.
Ogwira ntchito komanso anzeru
Kusintha kosalekeza kwa ethel ether ether kumathandizira ufa wa putty kuti ukhalebe wokhazikika m'malo ovuta. Mwachitsanzo, kudzera mu ma molecular kukonzekera ndi kuwonjezera kwa zowonjezera, putty ufa wamphamvu umakhala ndi mphamvu komanso kudziletsa, kupanga zomangira molimbika komanso zothandiza.
Kusiyanasiyana
Ndikuwongolera zofunikira za ufa, cellulose eder zimathanso kupanga ufa wowonjezera ngati antibacterial, anti-geheduw, ndi anti-uv kuti akwaniritse zosowa za pulogalamu yapadera.
Kugwiritsa ntchito cellulose ether mu ufa wa punty sikungopangitsa kuti pakhale magwiridwe antchito ndi kukhazikika kwa ufa wokongoletsa wamakono, kukwaniritsa zofunikira za kukongoletsa kwamakono, kusalala ndi kukhazikika. . Ndi chitukuko chopitilira pa malonda omanga, kugwiritsa ntchito cellose kukhala ndi ufa wa punty kumakhala kochulukirapo, kukankha zinthu zokongoletsera, kukankha zinthu zokongoletsera kwambiri ndi kuteteza chilengedwe.
