Cellulose etherndi gawo lopanda tanthauzo la ionic, lomwe ndi losungunulira madzi ndi solveleble. Imakhala ndi zovuta zosiyanasiyana m'mafakitale osiyanasiyana. Mwachitsanzo, m'matoto omanga mankhwala, ili ndi zotsatirazi zotsatila: Mu mankhwala a Polyvinyl chloride, ndi emulsiferier ndi obalalika; M'makampani opanga mankhwala, ndi mtengo wowonda komanso wowotcha mabuku, etc., chifukwa cellulose imakhala ndi mitundu yosiyanasiyana yopanga, motero magawo ake ofunsira ndi ochulukirapo. Kenako, ndidzayang'ana pa kugwiritsa ntchito ndi ntchito ya ethel ether mu chilengedwe chomangira zachilengedwe.
1. Mu utoto wa mochedwa
Mu makampani opanga mafoka a Matalx atracy, hydroxyethyl cellulose iyenera kusankhidwa. Chilinganizo chachikulu cha ma virus ndi RT30000-50000, ndipo Mlingo wa mawu nthawi zambiri umakhala 1.5 ‰ -2. Ntchito yayikulu ya hydroxyethyl mu utoto wa mochedwa Hydroxyethyl ethyl 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 zogwiritsira ntchito:
I. Onjezani mwachindunji kupanga:
Njira iyi iyenera kusankha hydroxyethyl cellulose yachedwa kuchedwa - hydroxyethyl cellulose ndi nthawi yofananira kwa mphindi 30. Masitepe ake ndi awa: Mpaka zida zonse za glanular zimanyowa ④add zina zowonjezera komanso zowonjezera zowonjezera, etc.
Ⅱ. Okonzeka ndi amayi mowa kwambiri pogwiritsa ntchito pambuyo pake:
Njirayi imatha kusankha mtundu wa nthawi yomweyo, ndipo ali ndi anti-Phulitsalew zotsatira cellulose. Ubwino wa njirayi ndikuti umasinthasintha kwambiri ndipo amatha kuwonjezeredwa mwachindunji penti ya latex. Njira yokonzekerayo ndi yofanana ndi masitepe ① - ④.
Ⅲ. Konzekerani mu phala logwiritsira ntchito pambuyo pake:
Popeza ma sodic okhazikika ndi osauka (osasunthika) a hydroxyethyl, izi sol sol angagwiritsidwe ntchito kupanga phala. Ogwiritsa ntchito solic yemwe amapezeka kwambiri ndi zakumwa zopangidwa ndi utoto wa utoto wa latex, monga ethylene glycol, Propylene Glycol, ndi othandizira mafilimu (monga ma mestylene glycol). Porridge hydroththyl cellulose imatha kuwonjezeredwa mwachindunji penti. Pitilizani kusuntha mpaka kusungunuka kwathunthu.
2. Pamalo a khoma
Pakadali pano, m'mizinda yambiri m'dziko langa, malo osokoneza bongo komanso ophatikizika amayamikiridwa ndi anthu. Imapangidwa ndi acetal zomwe zimamwa vinyl mowa komanso formaldehyde. Chifukwa chake, zinthuzi zimachotsedwa pang'onopang'ono ndi anthu, ndipo mankhwala opanga a Eleal Ether amagwiritsidwa ntchito m'malo mwa izi. Ndiye kuti, pakukula kwa zida zomangira zomangira, cellulose ndi zinthu zokhazokha.
M'kunjenjemera ndi madzi, amagawidwa m'mitundu iwiri: ufa wowuma ndi phala. Among these two kinds of putty, hydroxypropyl methylcellulose is generally selected, and the viscosity specification is generally between 80,000-90,000. Udindowu ndi kusungidwa kwamadzi, kulumikizana, kuphatikizika ndi zina zotero.
Popeza njira zopangira zosiyanasiyana ndizosiyana, ena ndi a calcium, sitacium, simenti yoyera, etc., etc.ction ya cellose mu Mitundu iwiri ndi yosiyananso. Ndalama zomwe zimawonjezeredwa pafupifupi 3 ‰ -5 ‰.
Pomanga makoma a khoma, popeza maziko a khoma amatenga mayamwidwe amadzi (madzi ammadzi a khoma la njerwa (madzi) Kuphatikiza ndi kusintha kwa dziko lakunja, ngati purty imataya madzi mwachangu, imabweretsa ming'alu kapena kuchotsedwa ufa, komwe kumamufooketsa mphamvu za paten. Chifukwa chake, kuwonjezera ma eleluse ether kumathetsa vutoli. Koma mtundu wa zosefera, makamaka mtundu wa calcium ndikofunika kwambiri. Chifukwa cha mafayilo akuluakulu a cellulose, malowo amalimbikitsidwanso, ndipo kusamba kwakukumba panthawi yomanga kumapeweranso, ndipo kumakhala komasuka komanso kupulumutsidwa.
3. Matope a Conner
Mu matope a Cyrete, kuti akwaniritse mphamvu zazikulu, simenti iyenera kukhala yochenjera. Makamaka nthawi yomanga chilimwe, mavalidwe mavalidwe a konkriti amataya madzi mwachangu, ndipo miyeso yaukalamba imagwiritsidwa ntchito mosasamala komanso kuwaza madzi. Kuwononga zinthu ndi ntchito zosokoneza. Chinsinsi chake ndikuti madziwo ali pamwamba, ndipo hydration wamkati sukwaniritsidwa. Chifukwa chake, yankho lavutoli ndikuwonjezera hydroxypropyll methylcellulose pakati pa 150,000 ndi 200,000 mpaka ku konkriti wayokha. , kuchuluka kwa pafupifupi 2 ‰ -3 ‰, ndipo kuchuluka kwa madzi kungawonjezedwe mpaka 92%. Njira yogwiritsira ntchito konkriti ya matope ndikuwonjezera madzi pambuyo pa ufa wouma umasakanikirana.
4. Mu gypsing gypsum, yolumikizana gypsum, gypsum
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, gypsum gypsum, gypsuid gypsum, ndi matayala a tile.
Kupaka gypsum ndi chinthu chapamwamba chojambulidwa pazida zamkati ndi denga. Khoma lopakidwa pakhoma lili ndi bwino komanso losalala, silimangokhala ufa, limalumikizidwa mwamphamvu mpaka pansi, alibe kusweka ndi kugwa, ndipo ali ndi moto wamoto; Gypsum Gypsum ndi mtundu watsopano womanga ma board oyenda omatira ndi zinthu zomata zopangidwa ndi gypsum ngati maziko apansi ndikuwonjezera zowonjezera zosiyanasiyana. Ndioyenera kugwirizanitsa pakati pa zida zamakhoma osiyanasiyana. Ndiwopanda zoopsa, zopanda pake, mawonekedwe abwino monga oyambilira, kukhazikika mwachangu, ndi kugwiririra mwamphamvu, ndikuthandizira pomanga mapanelo ndi kuletsa kumanga; Gypsum Poulicketing Wothandizira ndi gap filler pakati pa gypsum mapanelo ndi filler yokonza makoma ndi ming'alu.
Zinthu zama gypsum zimagwira ntchito zosiyanasiyana. Kuphatikiza pa gawo la gypsum ndi mafayilo okhudzana, nkhani yofunika ndikuti ma celluuse owonjezera a celhar owonjezera amagwira ntchito yotsogolera. Chifukwa gypsum yagawika gypsum gypsum ndi hemihydrate gypsum, gypsum yosiyanasiyana imakhala ndi zotsatirapo zosiyanasiyana pakuchita kwa mankhwalawo, motero, kusungidwa kwamadzi ndikubwezera kutsimikizira mtundu wa gypsum zomangira. Vuto lodziwika bwino la zinthuzi ndi lobowola komanso kusokonekera, ndipo mphamvu yoyamba siyingafikidwe. Kuti muthane ndi vutoli, ndikusankha mtundu wa cellulose ndi njira yolumikizira yokhotakhota. Pankhaniyi, methyl kapena hydroxypropyl 10000 nthawi zambiri amasankhidwa. -60000, kuchuluka kowonjezera kuli pakati pa 1.5 ‰ -2 ‰, ndi cellulose imayang'ana kwambiri kusungidwa kwamadzi ndikuyikanso mafuta.
Komabe, ndizosatheka kudalira ma cellulose ether, ndipo ndikofunikira kuwonjezera chobwezeretsa acitic acid kuti musakanikize ndi kugwiritsa ntchito popanda kukhumudwitsa mphamvu zoyambira.
Kusungidwa kwamadzi nthawi zambiri kumatanthauza madzi ambiri omwe adzatayika mwachilengedwe popanda madzi akunja. Ngati khomalo ndi louma kwambiri, madzi otumphuka ndi madzi otuluka pansi pa maziko adzachotsa madzi mwachangu, komanso yopanda komanso kuwonongeka kudzachitikanso kudzachitika.
Njira yogwiritsira ntchito imaphatikizika ndi ufa wouma. Ngati mukukonzekera yankho, chonde onani njira yothetsera yankho.
5. Matope okumba matope
Matope osonyeza matontheka ndi mtundu watsopano wa zotchingira za khoma lamkati kumpoto. Ndiwona ndi zinthu zam'mimba mwa kutchinga, matope ndi oyamwa. Munkhaniyi, ma cellulose amagwira ntchito yofunika kwambiri pogwirizanitsidwa komanso kulimbikira mphamvu. Nthawi zambiri amasankha methyl cellulose wokhala ndi mafayilo apamwamba (pafupifupi 150,000), mlingo nthawi zambiri umakhala pakati pa 2 ‰ -3 ‰), ndipo njira yogwiritsira ntchito ndi youma.
6..
Wothandizirayo ayenera kukhala HPNC20000, ndipo matayala amalume ayenera kupitirira 100,000. Gawolo liyenera kugwiritsidwa ntchito ngati thiccener, lomwe limatha kusintha mphamvu zokhala ndi mivi.
