Hydroxypropyl methylcellulose imagawidwa m'mitundu iwiri: mtundu wamba wosungunuka ndi madzi ozizira nthawi yomweyo.
Hydroxypropyl methylcellulose amagwiritsa ntchito
1. Gulu la Gypsum Muzinthu zamtundu wa gypsum, ma ether a cellulose amagwiritsidwa ntchito kwambiri kusunga madzi ndikuwonjezera kusalala.Onse pamodzi amapereka mpumulo.Ikhoza kuthetsa kukayikira kwa ng'oma yowonongeka ndi mphamvu zoyamba panthawi yomanga ndikuwonjezera nthawi yogwira ntchito.
2. Mu putty wa zinthu za simenti, cellulose ether makamaka imagwira ntchito yosungira madzi, kumamatira ndi kusalala, kuteteza ming'alu ndi kutaya madzi m'thupi chifukwa cha kutaya madzi ochulukirapo, ndipo palimodzi kumathandizira kumamatira kwa putty ndikuchepetsa kuchitika kwa ntchito yomanga. .sagging chodabwitsa, ndi kupanga kumanga bwino bwino.
3. Utoto wa latex M'makampani okutira, ma cellulose ethers angagwiritsidwe ntchito ngati opanga mafilimu, thickeners, emulsifiers ndi stabilizers, kuwapangitsa kukhala ndi kukana kwabwino kwa abrasion, yunifolomu yophimba ntchito, kumamatira ndi PH mtengo, ndikukhala ndi Kupititsa patsogolo kugwedezeka kwapamwamba.Zimagwiranso ntchito bwino kuphatikiza ndi zosungunulira za organic, ndipo kusungirako kwake kwamadzi kwambiri kumapangitsa kuti ikhale yabwino kwambiri pakutsuka ndi kusanja.
4. Interface agent Amagwiritsidwa ntchito kwambiri ngati thickener, amatha kuwonjezera mphamvu zolimba ndi kukameta ubweya, kukonza zokutira pamwamba, ndikuwonjezera kumamatira ndi mphamvu zomangirira.
5. Kunja kwa khoma lotchingira matope The cellulose ether m'nkhaniyi ikuyang'ana pa kugwirizana ndi kuonjezera mphamvu, kupangitsa matope kuti azigwiritsidwa ntchito mosavuta ndikuwongolera bwino ntchito.Anti-sag effect, ntchito yosungira madzi yapamwamba imatha kutalikitsa nthawi yautumiki wamatope, kuwongolera kukana kufupikitsa ndi kusweka, kuwongolera mawonekedwe apamwamba ndikuwonjezera mphamvu zamagwirizano.
6. Zoumba za zisa M'chisa chatsopano cha uchi, zinthuzo zimakhala ndi kusalala, kusunga madzi ndi mphamvu.
7. Sealant, suture Kuphatikizika kwa cellulose ether kumapangitsa kuti ikhale yomatira bwino kwambiri m'mphepete, kuchepetsa kuchepa kwapang'onopang'ono komanso kukana kuvala kwapamwamba, ndikuteteza deta yoyambira ku kuwonongeka kwamakina, kuteteza kukhudzika kwa zomanga zonse.
8. Kudziyimira pawokha Kukhazikika kokhazikika kwa cellulose ether kumatsimikizira kuti madzi amadzimadzi komanso odziyendetsa okha, komanso kusungirako madzi ogwiritsira ntchito kumapangitsa kuti akhazikike mofulumira, kuchepetsa kusweka ndi kufupikitsa.
9. Kumanga matope pulasitala matope Kusungirako kwamadzi kwakukulu kumapangitsa kuti simenti ikhale ndi madzi okwanira, imawonjezera kwambiri mphamvu ya mgwirizano, ndipo panthawi imodzimodziyo imawonjezera mphamvu zowonongeka ndi zometa ubweya, zomwe zimapangitsa kuti ntchito yomanga ikhale yabwino komanso yogwira ntchito bwino.
10. Tile zomatira Kusungirako madzi kwakukulu sikufuna kulowetsedwa kapena kunyowetsa matailosi ndi zigawo zoyambira, zomwe zimakulitsa kwambiri mphamvu ya mgwirizano, nthawi yayitali yomanga slurry, zomangamanga zabwino ndi yunifolomu, zomangamanga zosavuta, komanso zotsutsana ndi kusamuka.
Disolution njira
1. Tengani madzi otentha ofunikira, muyike mu chidebe ndikuwotchera pamwamba pa 85 ° C, ndipo pang'onopang'ono yonjezerani mankhwalawa pansi pa kuyambitsa pang'onopang'ono.Ma cellulose amayandama pamadzi poyamba, koma amamwazikana pang'onopang'ono kupanga matope ofanana.Kuziziritsa njira ndi oyambitsa.
2. Kapena tenthetsani 1/3 kapena 2/3 ya madzi otentha ku 85— kapena kupitirira apo, onjezani mapadi kuti mutenge madzi otentha, kenaka yikani madzi ozizira otsalawo, pitirizani kusonkhezera, ndi kuziziritsa osakanizawo.
Kusamalitsa
Ma viscosity osiyanasiyana (60,000, 75,000, 80,000, 100,000), odzaza ndi ng'oma zamakatoni zokhala ndi filimu ya polyethylene, kulemera kwa ukonde pa ng'oma: 25kg.Pewani dzuwa, mvula ndi chinyezi panthawi yosungira ndi kuyendetsa.
