Hydroxypropyl methylcellulose imagawidwa m'magulu awiri: mtundu wamba wa hot-melt ndi mtundu wa cold-water instant.
Kugwiritsa ntchito hydroxypropyl methylcellulose
1. Mndandanda wa Gypsum Mu zinthu zopangidwa ndi gypsum, ma cellulose ether amagwiritsidwa ntchito kwambiri kusunga madzi ndikuwonjezera kusalala. Pamodzi amapereka mpumulo. Imatha kuthetsa kukayikira kwa kusweka kwa ng'oma ndi mphamvu yoyambirira panthawi yomanga ndikuwonjezera nthawi yogwira ntchito.
2. Mu putty ya zinthu za simenti, cellulose ether imagwira ntchito makamaka yosunga madzi, kumamatira ndi kusalala, kupewa ming'alu ndi kutaya madzi chifukwa cha kutayika kwa madzi ambiri, ndipo pamodzi zimathandizira kumamatira kwa putty ndikuchepetsa kuchitika kwa njira yomanga, ndikupangitsa kuti zomangamanga zikhale bwino.
3. Utoto wa Latex Mu makampani opanga utoto, ma ether a cellulose angagwiritsidwe ntchito ngati zinthu zopangira filimu, zothina, zosakaniza ndi zokhazikika, zomwe zimapangitsa kuti zikhale zolimba bwino, zogwira ntchito mofanana, zomatira komanso PH, komanso zimakhala ndi mphamvu yabwino pamwamba. Imagwiranso ntchito bwino pamodzi ndi zinthu zachilengedwe zosungunulira, ndipo kusunga kwake madzi ambiri kumapangitsa kuti ikhale yabwino kwambiri potsuka ndi kuyeretsa.
4. Chogwirizira cholumikizira Chimagwiritsidwa ntchito makamaka ngati chokhuthala, chimatha kuwonjezera mphamvu yokoka ndi kumeta, kukonza zokutira pamwamba, ndikuwonjezera mphamvu yomatira ndi yolumikizana.
5. Chophimba chakunja cha khoma Chophimba cha cellulose ether chomwe chili m'nkhaniyi chimayang'ana kwambiri pakulumikiza ndi kuwonjezera mphamvu, kupangitsa kuti chophimbacho chikhale chosavuta kugwiritsa ntchito komanso kukonza magwiridwe antchito. Mphamvu yoletsa kutsika, ntchito yabwino yosunga madzi imatha kutalikitsa nthawi yogwirira ntchito ya chophimbacho, kuonjezera kukana kufupika ndi kusweka, kukweza ubwino wa pamwamba ndikuwonjezera mphamvu ya chogwiriracho.
6. Zoumba za uchi Mu zoumba zatsopano za uchi, zinthuzo zimakhala zosalala, zosunga madzi komanso zolimba.
7. Chotsekera, chokokera Kuwonjezeredwa kwa ether ya cellulose kumapangitsa kuti ikhale ndi kumatirira kwabwino kwambiri m'mphepete, kuchepetsa kuchepa kwa mphamvu komanso kukana kuwonongeka kwambiri, komanso kuteteza deta yapansi ku kuwonongeka kwa makina, kuteteza kukhudzidwa kwa kunyowa pa zomangamanga zonse.
8. Kudzilungamitsa Kokhazikika kwa ether ya cellulose kumatsimikizira kusinthasintha kwabwino komanso kuthekera kodzilungamitsa, ndipo kuchuluka kwa madzi ogwirira ntchito kumathandiza kuti ikhazikike mwachangu, kuchepetsa ming'alu ndi kufupikitsa.
9. Kumanga matope opaka matope Kusunga madzi ambiri kumapangitsa simenti kukhala ndi madzi okwanira, kumawonjezera mphamvu ya chigwirizano, komanso nthawi yomweyo kumawonjezera mphamvu yokoka ndi kumeta, zomwe zimapangitsa kuti ntchito yomanga ikhale yabwino komanso kuti ntchito igwire bwino ntchito.
10. Chomatira cha matailosi Kusunga madzi ambiri sikufuna kuti matailosi ndi zigawo za pansi zilowetsedwe kapena kunyowetsedwa, zomwe zimapangitsa kuti mphamvu ya chigwirizanocho ikhale yolimba, nthawi yayitali yomanga matope, kapangidwe kake kosalala komanso kofanana, kapangidwe kosavuta, komanso koletsa kusamuka bwino.
Njira yosungunula
1. Tengani madzi otentha ofunikira, muwaike mu chidebe ndikutenthetsa mpaka madigiri 85 Celsius, ndipo pang'onopang'ono onjezerani mankhwalawa mukasakaniza pang'onopang'ono. Cellulose imayandama pamadzi poyamba, koma pang'onopang'ono imafalikira kuti ipange slurry yofanana. Ziziritsani yankholo ndi kusakaniza.
2. Kapena tenthetsani 1/3 kapena 2/3 ya madzi otentha kufika pa 85— kapena kuposerapo, onjezerani cellulose kuti mupeze slurry ya madzi otentha, kenako onjezerani madzi ozizira otsala, pitirizani kusakaniza, ndikuziziritsa chisakanizocho.
Kusamalitsa
Kukhuthala kosiyanasiyana (60,000, 75,000, 80,000, 100,000), kodzazidwa m'mabokosi okhala ndi filimu ya polyethylene, kulemera konse kwa golomu iliyonse: 25kg. Pewani dzuwa, mvula ndi chinyezi panthawi yosungira ndi kunyamula.
