Gypsum (Caso₄₂₂o) ndi zomangamanga zogwiritsidwa ntchito ndi mafakitale, ndipo ntchito zake zimaphatikizapo kumanga pulasitala, etc. Mavutowa amachepetsa kugwiritsa ntchito ntchito ndi moyo wa mankhwala a gypsum. Pofuna kukonza zophophonya izi, ma cellulose owonjezera nthawi zambiri amawonjezeredwa ndi mankhwala a gypsum. Kuphatikiza kwa cellulose kumatha kusintha zinthu zothandizira gypsum, motero zimalimbikitsa mpikisano wawo pamsika.
1. Kupititsa patsogolo ntchito
Rheogy kukhathamiritsa
Gypsum imafunikira madzi abwino komanso kugwirira ntchito. Ma cellulose owonjezera amatha kusintha zopanda pake za gypsum slurry. Ma cellulose amakulitsa m'madzi kuti apange yankho lalitali, lomwe limatha kuwonjezera kuchuluka kwa gypsum ndikusintha kuchuluka kwa gypsum, motero ndikuchepetsa kusalala kwa gypsum ndi othana. Khalidwe ili limafunikira kwambiri kupukutira gypsum kuthira ndi kusintha kwakanthawi, chifukwa zimathandiza kuwongolera madzi osalala, pewani kubereka ndi magazi, ndikusintha mtundu womanga.
Kusunga kwamadzi kokweza
Cellulose amatha kusintha madzi osunga madzi a gypsum. Gypsum imafuna madzi kuti mumalize ntchito yolimba panthawi ya hydration. Kusungidwa kwabwino kumatha kulepheretsa madzi mwachangu kwambiri panthawi yolimba, potero kuwonetsetsa kuti ndi mphamvu ya gypsum ndi kukonza mphamvu zake zomaliza. Ma cellulose amapanga colloid yomwe imagawana madzi mozungulira tinthu ta gypsum, zomwe zimalepheretsa kuwonongeka kwa madzi mwachangu.
Luso la anti-sag
Mu gypsum kuphatikiza mafomu, kukana kwa sayansi ndi chizindikiro chofunikira. Kuphatikiza kwa cellulose kumatha kuwonjezera mafayilo a gypsum slurry, kulola kuti zigwirizane bwino kwambiri panthawi yomanga, ndikuchepetsa yunifolomu ndi kukhazikika kwa chimbudzi.
2. Thandizo makina
Kulimbana Kwambiri
Mafuta a cellulose amatha kusintha zinthu zosokoneza zida zama gypsum. Zinthu zama gypsum zidzakhala zowuma mu nthawi yolimba, zomwe zimapangitsa kuti kupsinjika kwamkati ndi mapangidwe osavuta kwa ming'alu. Mafuta a cellulose amatha kupanga mawonekedwe a mitundu itatu ya gypsum matrix, osokoneza bongo, kulepheretsa kukula kwa ming'alu, potengera kukana kwa zinthuzo. Izi zimachita mbali yofunika kwambiri posintha moyo wa Sypsum mabodi a gypsum, pulasitala yokongoletsa ndi zinthu zina.
Kuchulukitsa
Mafuta a cellulose amatha kukulitsa ntchito ya mankhwala a gypsum ndikuchepetsa. Zinthu za gypsum zomwe zimakhala zodzikongoletsera komanso zowoneka bwino zikasokonekera kapena kuwerama. Kuphatikiza kwa ulusi wa cellulose kumatha kupatsanso zovuta zina, kulola kuti nkhaniyo ikhale ndi kufooka kwabwino mukamapanikizika ndikuchepetsa kulephera kwa Brity. Khalidwe ili limakhala lofunikira kwambiri mu gypsum board ndi gypsum zokongoletsera zokongoletsera, chifukwa mankhwalawa amatha kukhudzidwa ndi mphamvu zakunja pakugwiritsa ntchito.
Sinthani Mphamvu Zopanda Mphamvu
Mafuta a cellulose amakhalanso ndi mphamvu kwambiri pa mphamvu yothana ndi zinthu za gypsum. Mafuta a cellulose amatha kupanga mawonekedwe olimbikitsa ku matrism matrix ndikuwonjezera mphamvu yake yothera. Izi ndizopindulitsa kwambiri zosinthana ndi gypsum bolodi, popeza kuchuluka kwa mphamvu kumawonjezera mwayi wokhala ndi mwayi wogwira ntchito ndi moyo wa bolodi.
3. Kusanja kulimba
Kuthetsa Madzi Kulimbana
Kuphatikiza kwa cellulose kumatha kukonza madzi kukana kwa gypsum. Zida za gypsum zidzafewetsa atatha kuyamwa madzi ndi mphamvu zawo zimachepa, motero zimakhudza moyo wawo. Cellulose amatha kupanga filimu yoteteza padziko lapansi kuti muchepetse kulowetsedwa kwa chinyezi, potero kumawongolera madzi kukana. Kulimbana ndi madzi kumatha kukulitsa moyo wa mankhwala a gypsum zinthu zachilengedwe komanso kuchepetsa kuchepa kwa madontho oyambitsidwa ndi madzi otengeka ndi kufewetsa.
Pewani tsankho
Cellulose imalepheretsa tsankho pakupanga zida zama gypsum. Cellulose imatha kukhazikika pa tinthu tating'onoting'ono to gypsum slurry, kupewa tinthu tating'onoting'ono tinthu tating'onoting'ono tikulumbirira tinthu tating'onoting'ono titayandama, potero kuonetsetsa kufanana kwa zinthuzo. Izi ndizofunikira kwambiri kukonza mtundu ndi kusasinthika kwa zinthu zopaka pulasitala.
Kuzizira ndi kutha kwa thaw
Kuphatikiza kwa cellulose kumatha kukonzanso kukana kwa zakuthambo za zida zama gypsum. M'madera ozizira, zinthu zamankhwala zimatha kusinthidwa mobwerezabwereza zamtundu wa Freeze-thaw, zomwe zimapangitsa kuwonongeka kwa zinthuzo. Ma cellulose amatha kuchepetsa nkhawa zamkati zomwe zimapangidwa munthawi yozizira komanso yochepetsera ndikusintha zolimbitsa thupi kudzera mu madzi ake osungira madzi komanso zolimbikitsa.
4. Kuteteza zachilengedwe ndi chilengedwe
Kukwanitsa
Cellulose ndichilengedwe, zosinthika zopangidwa ndi mbewu zomwe zimakhala zosangalatsa komanso zokhazikika. Pogwiritsa ntchito cellulose monga zowonjezera kwa zinthu zama gypsum osati kumakwaniritsa zofunika za chilengedwe, komanso amachepetsa kudalira zomwe sizikhala zotsalira.
Biodegradiity
Cellulose ali ndi biodegradiity yabwino, zomwe zikutanthauza kuti pambuyo pa zinthu zama gypsum zimatayidwa, cellulose imatha kuwonongeka mwachilengedwe popanda kuwononga chilengedwe. Izi zili ndi phindu lachilengedwe poyerekeza ndi ulusi wopangidwa.
5. Kugwiritsa ntchito ntchito
Zoyenera kusiyanasiyana kwa gypsum
Zosiyanasiyana za cellulose zimayenera kugwiritsa ntchito zinthu zosiyanasiyana zama gypsum, kuphatikizapo duwall, pulasitala yokongoletsa, mbale zokongoletsera, pulasitala, ndi zina zambiri. Mitundu yosiyanasiyana ya ma cellulose otuluka (monga hydroxypropyl methy celyolose, carboxymethyl cellulose, etc.) imasankhidwa malinga ndi zofunikira mwatsatanetsatane kuti mukwaniritse njira yabwino yosinthira.
Sinthani zomangamanga zosiyanasiyana
Maole owonjezera a cellulose amawonetsa kusinthasintha bwino pansi pa zomangamanga zosiyanasiyana. Mwachitsanzo, ma cellulose amatha kukonzanso magwiridwe antchito a gypsum slurry kapena kutentha kwambiri. Katunduyu amalola zinthu zochokera ku Gypsum kuti ziwoneke bwino pamachitidwe osiyanasiyana.
Kugwiritsa ntchito cellulose mu gypsum-zochokera kumagetsi kumapangitsa kuti pakhale zofunikira kwambiri kwa gypsum-zopangidwa mwaluso posintha ntchito, kukulitsa mphamvu, kukulitsa chilengedwe komanso kupereka zabwino zachilengedwe. Zotsatira zosinthika izi zimathandizira kuti Gypsum zinthu zizikwaniritsa ntchito yomanga ndi zokongoletsera ndikuwonjezera kukula kwawo. Ndi chitukuko chomanga zida zomangira, kugwiritsa ntchito kwa cellulose ndi zochokera ku gypsum zochokera kumadzi kudzakhala kochulukirapo komanso mwakuya, kupitiliza kupereka njira zapamwamba kwambiri, chilengedwe chochezeka.
