Cellulose ether (CE) ndi zopangidwa ndi polima zochokera ku cellulose wachilengedwe ndipo zimagwiritsidwa ntchito kwambiri popanga, zofukizira, mankhwala, zodzoladzola ndi minda ina. Pali mitundu yosiyanasiyana ya cellulose yolimba, yomwe ndi wamba imaphatikizapo ma hydroxypropyll methylcellulose (hpmc), hydroxethyl cellulose (MC). M'mapulogalamu osiyanasiyana, cellosesese adawonetsa zabwino zambiri malinga ndi kukhulupirika ndi magwiridwe, kukhala chinthu chofunikira kwambiri kukonza zinthu zakuthupi ndi moyo wa ntchito.
1. Sinthani ntchito zomanga
Mu gawo lomanga, cellulosesese yokhazikika nthawi zambiri imagwiritsidwa ntchito ngati otsatsa, osunga madzi ndi ma banga. M'matope, gypsum ndi simenti opangidwa ndi simenti, kukula kwa cellulose ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether amapangitsa kuti mafuta asungunuke ndi pulasitiki pomanga, kupewa magazi ndi magawano. Ma cellulose Ebel amathandizanso kulimbitsa ubale wa zinthuzo, kuonetsetsa kuti nkhaniyo imagawidwanso malinga ndi ntchito zomangamanga ndikutsatira bwino.
Hydroxypypyl methylcellulose (hpmc) amatha kusintha matope a matope, ndikupangitsa kuti ikhale yosavuta kuigwiritsa ntchito komanso kuchepera kuti mwina muchepetse, makamaka pomanga vertical. Kuphatikiza apo, kubwezeretsanso kwa cellulose ether kumatha kukulitsa nthawi ya matope, yomwe ndi yopindulitsa pakumanga kolondola kwa mapulojekiti ovuta. Izi zimathandiziranso kukonza bwino ntchito yomanga ndi mtundu wa kuchepetsa kuwonongeka kwa zinthu ndi zolakwa.
2. Kusunga kwamadzi
Chimodzi mwazofunikira za cellulose etrars ndi malo awo osungirako madzi abwino. Kusunga kwamadzi kumatanthauza kuthekera kwa maselo a cellulose kuti atengere ndikusunga chinyezi m'mawu, kuteteza chinyezi kapena kuwoneka bwino kwa zinthuzo pambuyo pomanga. Popanga zinthu zomanga monga zinthu zochokera ku Smentam ndi Gypsum-zopangidwa ndi ma cellulose ether ether ether ether amaonetsetsa kuti madzi amatha kutenga nawo mbali pazomwe zimachitika chifukwa cha kuchepa kwamitundu.
Zigawo zamadzi ndizofunikira kwambiri pakupanga zomangamanga. Mwachitsanzo, pa ntchito, cellulose eders ingathandize kuti chinyontho mu matope mu matope atasowa mwachangu kwambiri, potero ndikuwongolera chotsatsa ndi kulimba kwa matailosi. Mofananamo, m'munda wa zokumba, cellosese yokhazikika imatha kupewa kusanza kwa chinyezi, kulola kuti kuyambitsidwa kuti apange yunifolomu komanso malo owuma, kufalitsa moyo wa zokutira pambuyo pake.
3. Sinthani nyengo yanyengo
Kugwiritsa ntchito cellulose ede kumathandizanso kupezeka kwa zinthu zakuthupi, mwachitsanzo, kukana kwake zachilengedwe monga chinyezi, UV kuwala, nyengo ndi kutentha kwambiri komanso kutentha kwambiri. Izi ndizofunikira pakukhazikika kwa zinthu zomanga. Mwachitsanzo, kugwiritsa ntchito cellose etrage kumatha kukonza mtundu wa mafilimu ndikuwonjezera kuchuluka kwa zokutira, potengera kukana kwa ma utoto ndi kuwonongeka ndi kukalamba.
M'magawo a CELARE Izi zimathandiza kuti nyumbayo ikhalebe ndi umphumphu ndi zokopa kwa nthawi yayitali panthawi yayitali.

Mphamvu yakukula kwa maselo a cellulose mu mankhwala am'madzi amalola kuti asinthe zomwe zimapangitsa kuti zisinthe (monga kusokonekera, ndi zina) Mukuzimba ndi utoto, cellulose eya imasintha mapangidwe a utoto kuti zitsimikizire kuti sizingagwere kapena kugwetsa panthawi yogwiritsa ntchito ndikupanga zokutira mosalala. Izi sizingosintha zowongolera zomanga, komanso zimakulitsa kuvala kuvala kukana ndi kuwonongeka kukana kuyanjana.
Cellulose etrars amatenganso gawo lalikulu pakudzilimbitsa pansi. Kusintha kwake komanso kusintha kwake kumapangitsa kuti zinthuzo zizikhala bwino komanso zomwe zimapangitsa kuti zikhalepo, zimachepetsa m'badwo wa thonje ndi chilema, ndipo kukhazikika pansi.
5. Thandizani kukana kwa zinthu
Kusungidwa kwamadzi komanso kukula kwa cellulose ether ether ether kuwongolera kuthamanga kwa nkhaniyo ndikupewa mavuto oyambitsidwa ndi kuwonongeka kwa chinyezi. Makamaka pazita za matope ndi simenti, ethel ether ethembo ikhoza kufalitsa chinyontho muzinthu ndikuchepetsa kuchitika kwa ming'alu ya kuwira. Kuphatikiza apo, katundu wake wogwirizira bwino amathandizanso kuti zinthu zizigwirizana bwino ndi gawo lapansi ndikuwonjezera kukana kwa mawonekedwe.
Zovala zama gypsum-zochokera ku Gypsum, cellulose eder zimalepheretsa ming'alu yoyambitsidwa ndi madzi achangu mwachangu, kupanga khoma ndi denga lokhazikika mokhazikika komanso yosalala pakuyanika. Kukana kusokonekera kumeneku sikungowonjezera mawonekedwe a zinthuzo, komanso kumawonjezera moyo wake pantchito.
6. Sinthani kukana kwa chipongwe ndi kukana kwa mankhwala
Cellulose eders amathanso kusintha chiwonongeko ndi kukana kwamankhwala pazolinga zina. Popanga zochulukitsa zolimbitsa thupi komanso kuphatikizika kwamadzi, cellulose yokhazikika imatha kuchepetsa kuukira kwa mankhwala kapena chinyezi pazinthuzo. Izi ndizofunikira kwambiri m'mitundu ina yapadera, monga mbewu zamankhwala, mathithi am'madzi kapena madera apamwamba.
Kugwiritsa ntchito cellose eder mu madzi osaphika osati kumathandizira kulimba, komanso kumawonjezera kukana kwa mankhwala monga ma alkis, potengera mtengo wazokonza ndikuwongolera mtengo.
7. Kuteteza zachilengedwe ndi chitukuko chokhazikika
Cellulose ether ndi nkhani yobiriwira komanso yachilengedwe chifukwa imachokera ku zachilengedwe cellulose ndipo ndi biodegrad. Poyerekeza ndi zida za polymer, cellulose eders zimasokoneza chilengedwe ndipo sikumatulutsa zinthu zovulaza pakupanga. Chifukwa chake, kugwiritsa ntchito kwa cellulose kumayambitsa zofunikira za chilengedwe ndi chitukuko chokhazikika mu makampani omanga.
Ubwino wa celluse molingana ndi kukhazikika kwa kukhazikika ndi kugwira ntchito kumawonekera makamaka posungira madzi abwino kwambiri, kukulira, kutsatsa komanso kukana nyengo. Sizongosintha magwiridwe antchito omanga, komanso zimakulitsa kukana kwa zinthu zakuthupi, kukhazikika komanso kukana kuwonongeka, ndikuwonjezera moyo wankhani. Kuphatikiza apo, katundu wobiriwira komanso wachilengedwe wa cellulose ethel nawonso amapangitsa kuti ikhale gawo lofunikira pakupanga zamtsogolo.
