Kugwiritsa ntchito ndi ntchito ya ether ya cellulose mu zipangizo zosiyanasiyana zomangira

Cellulose ether ndi mtundu wa polima yopanda ionic semi-synthetic yokhala ndi madzi osungunuka komanso osungunuka, zomwe zimayambitsa maudindo osiyanasiyana m'mafakitale osiyanasiyana, mwachitsanzo, mu zipangizo zomangira mankhwala, ili ndi maudindo otsatirawa:

① chosungira madzi ② chokhuthala ③ kulinganiza ④ kupanga filimu ⑤ chomangirira

Mu makampani opanga PVC, ndi emulsifier, dispersant; mu makampani opanga mankhwala, ndi chinthu chomangirira komanso chowongolera zinthu zotulutsa mafupa pang'onopang'ono komanso molamulidwa, ndi zina zotero. Chifukwa chakuti cellulose ili ndi ntchito zosiyanasiyana zomwe zimapangitsa kuti ikhale yogwiritsidwa ntchito kwambiri. Zotsatirazi zikuyang'ana kwambiri pa kagwiritsidwe ntchito ndi ntchito ya cellulose ether mu zipangizo zosiyanasiyana zomangira.

(1) Mu putty ya pakhoma:

Pakadali pano, dziko lathu m'mizinda yambiri, putty yosalowa madzi, yosalowa madzi, komanso yosalowa madzi, yakhala ikukondedwa ndi anthu, m'zaka zingapo zoyambirira, chifukwa cha kugwiritsa ntchito guluu wopangidwa ndi putty womwe umawononga thanzi la anthu, guluu wopangidwa ndi polyvinyl alcohol ndi formaldehyde acetal reaction. Chifukwa chake, zinthuzi zimachotsedwa pang'onopang'ono ndi anthu, ndipo m'malo mwa zinthuzi ndi zinthu za cellulose ether, ndiko kuti, chitukuko cha zipangizo zomangira zosunga zachilengedwe, cellulose ndiye chinthu chokhacho chomwe chimagwiritsidwa ntchito.

Mu putty yosagwira madzi, putty imagawidwa mu ufa wouma ndi putty phala mitundu iwiri ya putty, mitundu iwiri ya putty nthawi zambiri imasankhidwa modified methyl cellulose ndi hydroxypropyl methyl mitundu iwiri ya mamasuliridwe a kukhuthala nthawi zambiri mu 30000-60000cps pakati pa yoyenera kwambiri, mu putty cellulose udindo waukulu ndi kusunga madzi, mgwirizano, mafuta ndi ntchito zina. Chifukwa cha opanga osiyanasiyana a putty, ena ndi imvi calcium, calcium yopepuka, simenti yoyera, etc., ena ndi ufa wa gypsum, calcium yoyera, calcium yopepuka, calcium yopepuka, etc., kotero njira ziwirizi zimasankhidwa kuti zisankhe mamasuliridwe a kukhuthala kwa cellulose ndi kuchuluka kwake sikufanana, kuchuluka kwa kukhuthala kwa 2 ‰ -3 ‰ kapena kuposerapo. Mu kukanda khoma putty, chifukwa cha khoma substrate ali ndi mlingo winawake wa kuyamwa madzi (mlingo wa kuyamwa madzi pakhoma la njerwa ndi 13%, konkire ndi 3-5%), pamodzi ndi dziko lakunja la evaporation, kotero ngati putty itataya madzi mwachangu kwambiri, idzapangitsa kuti pakhale ming'alu kapena de-ufa ndi zochitika zina, motero kufooketsa mphamvu ya putty, pachifukwa ichi, pambuyo powonjezera cellulose ether idzathetsa vutoli. Koma khalidwe la filler, makamaka khalidwe la imvi calcium, ndilofunikanso kwambiri.

Chifukwa cellulose ili ndi kukhuthala kwakukulu, motero kumawonjezeranso kumatirira kwa putty, komanso kupewa kumangidwa kwa chodabwitsa chopachika, ndikukanda pambuyo pa kumasuka kwambiri, kupulumutsa ntchito ndi zina zotero. Mu ufa wouma putty cellulose ether iyenera kukhala yoyenera kuwonjezera mfundo zambiri, kupanga kwake, kugwiritsa ntchito ndikosavuta, kudzaza ndi zowonjezera za ufa wouma wosakaniza wofanana kungakhale, kapangidwe kake ndikosavuta, madzi pamalopo, ndi kuchuluka kwake ndi kuchuluka kwake.

(2) matope a konkire:

Mu matope a konkire, omwe amafika pamlingo womaliza, simenti iyenera kusungunuka bwino, makamaka nthawi yachilimwe, madzi amatayika mofulumira kwambiri, ndipo njira yopezera madzi okwanira imateteza sprinkler, njira iyi ndi kuwononga madzi ndi zovuta zogwirira ntchito, chofunikira ndichakuti madzi amakhala pamwamba, ndipo madzi amkati sali okwanira, kotero yankho la vuto la njira yolumikizirana mu matope. Wothandizira kusunga madzi m'matope nthawi zambiri amasankha hydroxypropyl methyl kapena methyl cellulose, ma viscosity specifications pakati pa 20000 - 60000cps, onjezani 2% - 3%. Mozungulira, kuchuluka kwa madzi osungira madzi kumatha kuwonjezeka kufika pa 85%, kugwiritsa ntchito matope a konkire munjira ya ufa wouma wosakanikirana bwino m'madzi kungakhale.

(3) mu pulasitala wa stucco, pulasitala womangirira, pulasitala wophatikizidwa:

Ndi chitukuko chachangu cha makampani omanga, kufunikira kwa anthu kwa zipangizo zatsopano zomangira kukukulirakuliranso. Chifukwa cha kuchuluka kwa chidziwitso cha anthu chokhudza kuteteza chilengedwe komanso kupititsa patsogolo magwiridwe antchito omanga, zinthu zopangidwa ndi gypsum zopangidwa ndi simenti zapangidwa mwachangu. Pakadali pano, zinthu zodziwika bwino za gypsum ndi brushing plaster, bonding plaster, embedded plaster, tile glue ndi zina zotero. Brush plaster ndi mtundu wa zinthu zabwino kwambiri zomangira khoma lamkati ndi bolodi lapamwamba, zomwe zimapangitsa kuti khoma likhale lofewa komanso losalala, palibe ufa womwe umagwa ndipo gawo lapansi limalumikizidwa mwamphamvu popanda kusweka kapena kugwa, ndipo limagwira ntchito yoteteza moto; bonding plaster ndi mtundu watsopano wa bonding board yopepuka yomangira, yomwe imapangidwa ndi gypsum ngati maziko ndipo imawonjezeredwa ndi zowonjezera zosiyanasiyana, ndipo ndiyoyenera kulumikiza mitundu yonse ya zinthu zopanda chilengedwe zomangira khoma, zomwe zimakhala ndi mawonekedwe osaopsa, osakoma, ouma mwachangu komanso omangira mwachangu. Ndi yoyenera kulumikiza pakati pa mitundu yosiyanasiyana ya zipangizo zomangira zopanda chilengedwe, zokhala ndi zosakhala poizoni, zopanda fungo, zofulumira, zolimba, zolimba ndi zina, ndipo ndi zinthu zothandizira popanga matabwa omangira ndi mabuloko; gypsum caulk ndi chodzaza mipata pakati pa matabwa a gypsum komanso chodzaza makoma ndi ming'alu.

Zipangizo za gypsum izi zili ndi ntchito zosiyanasiyana, kuwonjezera pa gypsum ndi zodzaza zina zofanana, nkhani yaikulu ndi kuwonjezera zowonjezera za cellulose ether zomwe zimagwira ntchito yotsogola. Popeza gypsum imagawidwa mu gypsum yopanda madzi ndi gypsum yopanda madzi, gypsum yosiyana imakhala ndi zotsatira zosiyana pa magwiridwe antchito a chinthucho, kotero kukhuthala, kusunga madzi ndi kuchedwa kwa zipangizo zomangira gypsum kumatsimikizira ubwino wa zipangizo zomangira gypsum. Vuto lofala la zipangizozi ndi kusweka ndi kusweka, mphamvu yoyamba siingapezeke, kuti tithetse vutoli, ndikusankha mtundu wa cellulose ndi retarder composite magwiritsidwe ntchito a vutoli, pankhaniyi, kusankha kwakukulu kwa methyl kapena hydroxypropylmethyl 30,000 - 60,000cps, kuchuluka kwa kuwonjezera kwa 1.5% - 2%. Pakati pa, cellulose yomwe cholinga chake ndi kudzoza madzi oletsa kusunga madzi. Komabe, mu izi, kugwiritsa ntchito etha ya cellulose monga retarder sikunakwaniritsidwe, komanso kugwiritsa ntchito kosakanikirana kwa citric acid retarder sikungakhudze mphamvu yoyambirira.

Kuchuluka kwa madzi omwe amasungidwa nthawi zambiri kumatanthauza momwe madzi amayamwidwira kunja, kuchuluka kwa madzi omwe amatayika mwachilengedwe, ngati khoma lili louma, madzi omwe amayamwitsidwa pamwamba pa nthaka komanso kutayika kwa madzi mwachangu kwambiri, zomwezo zimachitika chifukwa cha ng'oma zopanda kanthu, ming'alu. Njira iyi yogwiritsira ntchito ufa wouma wosakaniza, ngati kukonzekera yankho kungatanthauze kukonzekera yankho.

(4) Chotenthetsera cha kutentha

Chophimba choteteza kutentha ndi mtundu watsopano wa zinthu zotetezera kutentha mkati mwa khoma, ndi zinthu zotetezera kutentha zomwe zimapangidwa ndi zinthu zotetezera kutentha, chophimba ndi cholumikizira. Cellulose mu chinthuchi, chomwe chimayang'ana kwambiri pakugwirizanitsa, chimawonjezera mphamvu. Nthawi zambiri sankhani methyl cellulose Kukhuthala kwakukulu (10000cps kapena kuposerapo), mlingo nthawi zambiri umakhala pakati pa 2‰-3‰, pogwiritsa ntchito njira yosakaniza ufa wouma.
