Cellulose ether ndi polymer yopanga iyaic-yopanga, yomwe ndi yosungunuka 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 ma tepi a latex, kusankha hydroxyethyl cellulose, zomwe zikuwoneka kuti zikufanana ndi ma vb30000-50000-50000-50000-50000-50000-50000-50000-50000-50000-50000-50000-50000-50000-50000-50000-50000-50000-50000-50000-50000. Ntchito yayikulu ya hydroxyethyl mu utoto wa latex ndi kunenepa, muchepetse kufalikira kwa pigment, kukhazikika kwa zigawozo, ndikuwonjezera mamasukidwe a zomangamanga: Hydroxyethyl cellulose ndiyofunika kugwiritsa ntchito. Itha kusungunuka m'madzi ozizira ndi madzi otentha, ndipo sizikhudzidwa ndi mtengo wa pH. Itha kugwiritsidwa ntchito bwino pakati pa PIMU 2 ndi 12. Njira zogwiritsira ntchito ndizotere:
(1) Onjezani mwachindunji kupanga:
Panjira imeneyi, hydroxethyl cellulose yochedwa kuchedwa kuyenera kusankhidwa, ndipo hydroxyethyl cellulose wokhala ndi mphindi zopitilira 30 amagwiritsidwa ntchito. Masitepewo ndi awa: Zipangizo zonse za granlar zimanyowa - zina zowonjezera komanso zowonjezera zowonjezera, etc.
(2) okonzeka ndi zakumwa zakumwa zoledzeretsa 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.
(3).
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. Mwa mitundu iwiri iyi ya putty, yosinthidwa methyl cellulose ndi hydroxypropyl methyl iyenera kusankhidwa. Kutanthauzira kwa ma visto kuli pakati pa 30000-60000cps. Ntchito zazikuluzikulu za cellulose ndi madzi osungidwa ndi mafuta.
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 2 ‰ -3 ‰.
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.
Ndikosavuta kuwonjezera cellulose ether mu ufa. Kupanga ndi kugwiritsa ntchito kwake ndikosavuta. Zosefera ndi zowonjezera zimatha kukhala zophatikizika mu ufa wouma.
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 kugwirira ntchito kosavomerezeka, chinsinsi chake ndikuti madziwo sakukwanira, kotero yankho la mkati silinakwaniritsidwe kapena methyl cellulose, malingaliro a Viscclose ali pakati pa 20000-60000cps, ndi kuchuluka kwake ndi 2% -3%. Kusunga kwamadzi kumatha kuwonjezeka mpaka 85%. Njira yogwiritsira ntchito konkriti ya matope ndikusakaniza ufa wowuma kwambiri ndikuthira m'madzi.
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 labwino komanso losalala. Nyumba yatsopano yomanga zomatira ndi zinthu zomata zopangidwa ndi gypsum monga maziko a maziko ndi zowonjezera zosiyanasiyana. Ndioyenera kugwirizanitsa pakati pa zida zamakhoma osiyanasiyana. Ndiwopanda mphamvu, zopanda mphamvu, zoyambirira, zomangira mwachangu, kulumikizana kwamphamvu ndi zinthu zina, ndizothandiza pomanga matabwa ndikutchinjiriza; Gypsum Poulicketing ndi gap filler pakati pa mabodi a gypsum 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. Popeza gypsum agawidwa m'ma gypsum gypsum ndi hemihydrate gypsum, gypsum yosiyanasiyana imakhala ndi zotsatirapo zosiyanasiyana pakuchita kwa mankhwalawo, kusunthika kwa madzi ndikubweza kutsimikizira mtundu wa gypsum. 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. -60000cps, kuchuluka kowonjezera ndi 1.5% -2%. Mwa iwo, ma cellulose amayang'ana kwambiri kusungidwa kwamadzi komanso kutaya 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 yokhala ndi mamasukidwe apamwamba (pafupifupi 10000es), mlingo nthawi zambiri umakhala pakati pa 2 ‰ -3 ‰), ndipo njira yogwiritsira ntchito ufa ndi ufa wosakaniza.

Sankhani HPNC 20000cps ya wothandizirayo, sankhani 60000cps kapena kupitilira apo pamasamba, ndipo yang'anani pa Thicker mu mawonekedwe othandizira, omwe angakhale ndi mphamvu ya antile.
