Ma cellulose ether ndi mtundu wa zosapangidwa ndi zotupa zazitali zowoneka bwino kwambiri. Ili ndi mitundu iwiri ya kusungunuka ndi solvent-yosungunulira. Imakhala ndi zovuta zosiyanasiyana m'mafakitale osiyanasiyana. Mwachitsanzo, m'matoto omanga mankhwala, ili ndi zotsatirazi zotsatila: ①ater-wosunga chithandizo ②thickener ③ ②film-⑤bilm-⑤bindar; Mu makampani a PVC, ndi emulsiferier ndi obalalika; M'makampani opanga mankhwala, ndi mowa komanso chifukwa ma cellulose ali ndi mitundu yosiyanasiyana yophatikiza, imagwiritsidwanso ntchito kwambiri. Pansipa ndidzayang'ana pakugwiritsa ntchito ndi ntchito ya cellose etrade ku zida zomangamanga.
1. Mu utoto wa mochedwa
Mu makampani opanga mafoka a Matalx atracy, hydroxyethyl cellulose iyenera kusankhidwa. Chizindikiro cha ma virus ndi RT30000-50000000000000000000000000000000000000000-500000000000000-5000000000000-500000000000000-5000000000000-50000000000-5000000-5000000. Ntchito yayikulu ya hydroxyethyl mu utoto wa mochedwa ndi kunenepa, pewani mitu yazida, thandizani mafuta osokoneza bongo, ndipo imatha kusintha mamasukidwe a zinthu zomanga: hydroxyethyl ethy cellulose ndiyofunika kugwiritsa ntchito. Itha kusungunuka m'madzi ozizira ndi madzi otentha, ndipo sizikhudzidwa ndi mtengo wa pH. Itha kugwiritsidwa ntchito pakati pa mtengo wa 2 ndi 12. Pali njira zitatu zotsatirazi:
I. Onjezani mwachindunji kupanga:
Njira iyi iyenera kusankha hydroxyethyl cellulose yachedwa kuchedwa - hydroxyethyl cellulose ndi nthawi yofananira kwa mphindi 30. Kugwiritsa ntchito njira: Mpaka zida zonse za granolar zimanyowa kudzera ④ kuwonjezera zina zowonjezera komanso zowonjezera za alkaline, etc.
Ⅱ. Okonzeka ndi Mayi Kuledzera:
Njirayi imatha kusankha mtundu wa nthawi yomweyo, ndipo imakhudza cellulose. Ubwino wa njirayi ndikuti umasinthasintha kwambiri ndipo amatha kuwonjezeredwa mwachindunji pa utoto wa latex. Njira yokonzekererayo ndi yofanana ndi njira ya ① - ④.
Ⅲ. Pokonzekera phala longa ndi katundu:
Popeza ma sodic okhazikika ndi osavomerezeka (osavomerezeka) kwa magulu a hydroxyethyl, ma porridge amatha kupangidwa ndi ma sol sol. Ogwiritsa ntchito solic yemwe amapezeka kwambiri ndi zakumwa zopangidwa mwamphamvu mu utoto wa utoto wa latex, monga ethylene glycol, Propylene Glycol ndi fomu ya film (monga ma meterylene glycol). Porridge hydroththyl cellulose imatha kuwonjezeredwa mwachindunji penti. Pitilizani kusuntha mpaka kusungunuka kwathunthu.
2, khoma lowomba
Pakadali pano, malo achilengedwe omwe amasagwirizana ndi madzi komanso kuchuluka kwa mizinda yambiri m'dziko langa kwakhala kolemekezeka ndi anthu. Zaka zingapo zapitazi, chifukwa punty yopangidwa ndi gululo la zomangamanga gasi ndikuwononga anthu thanzi la anthu, zomangira zomangira zimakonzedwa ndi mowa wa vinyl. Chifukwa chake, izi zimachotsedwa pang'onopang'ono ndi anthu, ndipo mankhwala osokoneza bongo a Elel adasinthidwa ndi izi, ndiye kuti, kukula kwa zinthu zomanga zachilengedwe, cellulose ndiye zinthu zokhazo zomwe zilipo.
M'kunjenjemera ndi madzi, amagawidwa kukhala putty putty ndi putty phalo. Mwa mitundu iwiri iyi ya putty, kusinthidwa methyl cellulose ndi hydroxypropyl methyl nthawi zambiri amasankhidwa. Kutanthauzira kwa ma visto kuli pakati pa 30000-60000cps. Ntchito zazikuluzikulu za cellulose ndi madzi osungidwa ndi mafuta.
Popeza njira zopangira zosiyanasiyana ndizosiyana, zina ndi calcium, sitacium, etc., kotero ma calcium awiriwa amasankha maleya . Zowonjezera ndizokhudza 2 ‰ -3 ‰.
Pomanga khoma lokumba, chifukwa pansi pakhoma ili ndi mayamwidwe ena a njerwa (madzi am'madzi am'mimba ndi 13%, ndipo mayamwa amadzi a konkriti ndi 3-5%), yophatikizidwa ndi Kusintha kwa dziko lakunja, ngati chivundikirocho chimatha kusala kwambiri, chimatsogolera ku ming'alu kapena kuchotsedwa ufa ndi zochitika zina, potero amachepetsa mphamvu ya paten. Pachifukwa ichi, kuwonjezera ma elelusose ether amathetsa vutoli. Koma mtundu wa zosefera, makamaka mtundu wa calcium, ndikofunikira kwambiri. Chifukwa ma cellulose ali ndi mawonekedwe owoneka bwino, imawonjezeranso chisangalalo cha Detty, kupewa kusaka kwina pakumanga, ndipo ndikoyenera kukhala kotamandidwa komanso kupulumutsidwa.
3. Matope a Conner
Mu matope a Cyrete, kukwaniritsa mphamvu zomaliza, simenti iyenera kukhala yamafuta kwathunthu, makamaka munthawi yomanga chilimwe, imataya madzi mwachangu, ndipo miyeso yaukalamba imatengedwa kuti ikhalebe ndi madzi. Kuwononga zinthu komanso kugwirira ntchito kovomerezeka, fungulo ndiloti madzi amangokhala osakwanira, motero njira yamkati siyikukwanira, motero yankho lavutoli ndikuwonjezera ma hydroxyp pa cellose kapena methyl. Kutanthauzira kwa Viscty kuli pakati pa 20000-60000cps, kuchuluka kwake ndi pafupifupi 2 ‰ -3 ‰, ndipo kuchuluka kwa madzi kumatha kuwonjezeka mpaka 85%. Njira yogwiritsira ntchito konkriti ya matondo ndikusakaniza ufa wowuma mokwanira ndikuwonjezera madzi.
4. Mu pulasitala yopaka, yolumikizirana ndi pulasitala yolowera
Ndi kukula kwa makampani omanga, kufunikira kwa anthu kwa zinthu zatsopano kumawonjezera tsiku ndi tsiku. Chifukwa chakuwonjezereka kwa anthu oteteza zachilengedwe komanso kusinthasintha kwa luso la kapangidwe kake, zinthu za Cemewestous zayamba msanga. Pakadali pano, zinthu zodziwika bwino kwambiri za gypsum ndizovala gypsum, zomangira gypsum, zomata gypsum, tile zomata ndi zina.
Dulani ya Stucco ndi mtundu wa zinthu zapamwamba kwambiri zojambulira makoma ndi padenga. Makoma opaka ndi bwino ndi osalala, osataya ufa, mgwirizano wamphamvu mpaka gawo lapansi, usasweke ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikugwa, ndikuchotsa moto; pulasitala yolumikizira ndi mtundu wa pulasitala. Mtundu Watsopano Womanga Kumata Ading ndi zinthu zomata ndi zida zopangidwa ndi gypsum monga maziko apansi ndikuwonjezera zowonjezera zosiyanasiyana. Ndioyenera kugwirizanitsa pakati pa zida zamakhoma osiyanasiyana. Sikuti sizala zopweteka, zonunkhira, zimakhala ndi mawonekedwe a mphamvu zoyambirira, kukhala wotanganidwa kwambiri komanso kugwirizanitsa kwamphamvu, ndipo ndi zinthu zothandizira pomanga matabwa omanga ndi midadada;
Zinthu zama gypsum izi zimakhala ndi ntchito zingapo zosiyanasiyana, kuwonjezera pa gawo la gypsum ndi mafilimu ofunikira, vuto lowonjezera ndi lowonjezera la ethel ethel eyal yogawana. Popeza gypsum yagawika m'ma gyhydrite ndi hemamydram gypsum, gypsum yosiyanasiyana imakhala ndi zotsatira zosiyanasiyana pa ntchito, motero, kusungidwa kwamadzi ndikubwezera kutsimikizira mtundu wa zomangamanga gypsum. Vuto lodziwika bwino la zinthuzi ndi lopanda pake, ndipo mphamvu yoyamba silingafike. Kuti athane ndi vutoli, ndi vuto la kusankha mtundu wa cellulose ndi njira yolumikizira yokhotakhota. Pankhaniyi, methyl kapena hydroxypropyl 10000 nthawi zambiri amasankhidwa. -60000cps, kuchuluka kowonjezera kuli pakati pa 1.5 ‰ -2 ‰, zomwe zimachitika pa cellulose ndi kusungidwa kwamadzi, kutamalitsa ndi mafuta.
Komabe, sizotheka kudalira ma cellulose ether, ndipo ndikofunikira kuwonjezera chobwezeretsa acitic acid kusakaniza ndikugwiritsa ntchito kuti mphamvu yoyamba isakhudzidwe.
Kusunga kwamadzi nthawi zambiri kumatanthauza kutaya kwachilengedwe kwa madzi omwe amakhala osakhala ndi madzi akunja. Ngati khomalo ndi louma kwambiri, madzi ophatikizika ndi kusintha kwachilengedwe pamtunda kudzapangitsa kuti zinthu zisataye madzi mwachangu kwambiri, komanso yopanda komanso kuwonongeka kudzachitikanso.
Njira yogwiritsira ntchito imaphatikizika ndi ufa wouma. Ngati yankho lakonzedwa, chonde onani njira yokonzekera yankho.
5. Matope Otsimikiza
Matope okonda kutentha ndi mtundu watsopano wamatenthedwe amafuta amafuta kumpoto kwa Northern. Ndi zinthu za khoma zomwe zimapangidwa ndi zotchinga zamagetsi, matope ndi oyamwa. Munkhaniyi, ma cellulose amagwira ntchito yofunika kwambiri pogwirizanitsidwa komanso kulimbikira mphamvu. Nthawi zambiri amasankha methyl cellulose yokhala ndi mamasukidwe apamwamba (pafupifupi 10000), mlingo nthawi zambiri umakhala pakati pa 2 ‰ -3 ‰), ndipo njira yogwiritsira ntchito ndi njira yotsukira ufa.
6..
Wothandizirayo ndi HPNC20000cps, ndi matailesi otsatsa ndi oposa 60000cps. Mu gawo lothandizira, limagwiritsidwa ntchito makamaka ngati thicker, lomwe limatha kusintha mphamvu zokhala ndi mivi.
