Desulfurized gypsum ndi wopangidwa kuchokera ku flue gas desulfurization pamagetsi opangira malasha kapena mbewu zina zomwe zimagwiritsa ntchito mafuta okhala ndi sulfure.Chifukwa cha kukana kwambiri kwa moto, kukana kutentha ndi kukana chinyezi, wakhala akugwiritsidwa ntchito kwambiri muzomangamanga monga zomangira.Komabe, chimodzi mwazovuta zazikulu zogwiritsira ntchito gypsum desulfurized ndi kutentha kwake kwa hydration, zomwe zingayambitse mavuto monga kusweka ndi kusinthika panthawi yokonza ndi kuumitsa.Choncho, pakufunika kupeza njira zothandiza kuchepetsa kutentha kwa hydration wa gypsum desulfurized pamene kukhalabe makina katundu ndi katundu.
Ma cellulose ethers ndi zowonjezera zomwe zimagwiritsidwa ntchito m'makampani omanga kuti apititse patsogolo ntchito, mphamvu ndi kulimba kwa zipangizo zopangira simenti.Ndi polima yopanda poizoni, yowola, yongowonjezedwanso yochokera ku cellulose, organic pawiri padziko lonse lapansi.Ma cellulose ether amatha kupanga chokhazikika ngati gel osakaniza m'madzi, chomwe chingapangitse kusungidwa kwa madzi, kukana kwa sag komanso kusasinthika kwa zida zopangira simenti.Kuphatikiza apo, ma cellulose ethers amathanso kukhudza ma hydration ndi kukhazikitsa njira zazinthu zopangidwa ndi gypsum, zomwe zimakhudzanso makina awo ndi katundu.
Zotsatira za cellulose ether pa gypsum hydration ndi solidification process
Gypsum ndi calcium sulfate dihydrate pawiri yomwe imachita ndi madzi kupanga zolimba komanso zolimba za calcium sulfate hemihydrate blocks.Njira ya hydration ndi solidification ya gypsum ndizovuta ndipo imaphatikizapo magawo angapo, kuphatikiza nucleation, kukula, crystallization, ndi solidification.Kuchita koyamba kwa gypsum ndi madzi kumapanga kutentha kwakukulu, komwe kumatchedwa kutentha kwa hydration.Kutentha kumeneku kungayambitse kupsinjika kwa kutentha ndi kuchepa kwa zinthu zopangidwa ndi gypsum, zomwe zingayambitse ming'alu ndi zolakwika zina.
Ma cellulose ether amatha kukhudza hydration ndi kukhazikitsa njira za gypsum kudzera munjira zingapo.Choyamba, ma cellulose ethers amatha kusintha magwiridwe antchito komanso kusasinthika kwa zinthu zopangidwa ndi gypsum popanga kukhazikika kokhazikika komanso kofananira m'madzi.Izi zimachepetsa zofunikira za madzi ndikuwonjezera kuyenda kwa zinthuzo, potero kumathandizira hydration ndi kukhazikitsa ndondomeko.Kachiwiri, ma cellulose ether amatha kugwira ndikusunga chinyezi mkati mwa zinthuzo popanga maukonde ngati gel, potero kumapangitsa kuti zinthuzo zisungidwe bwino.Izi zimatalikitsa nthawi ya hydration ndikuchepetsa kuthekera kwa kupsinjika kwa kutentha ndi kuchepa.Chachitatu, ma cellulose ethers amatha kuchedwetsa magawo oyambilira a hydration mwa kutsatsa pamwamba pa makristasi a gypsum ndikulepheretsa kukula kwawo ndi kristalo.Izi zimachepetsa kuchuluka kwa kutentha kwa hydration ndikuchedwa kuyika nthawi.Chachinayi, ma cellulose ethers amatha kupititsa patsogolo makina ndi magwiridwe antchito a gypsum powonjezera mphamvu zawo, kulimba kwawo komanso kukana mapindikidwe.
Zomwe zimakhudza kutentha kwa hydration wa gypsum desulfurized
Kutentha kwa hydration ya desulfurized gypsum kumakhudzidwa ndi zinthu zosiyanasiyana, kuphatikizapo mankhwala, kukula kwa tinthu, chinyezi, kutentha ndi zowonjezera zomwe zimagwiritsidwa ntchito pazinthuzo.The mankhwala zikuchokera desulfurized gypsum zingasiyane malinga ndi mtundu wa mafuta ndi desulfurization ndondomeko ntchito.Nthawi zambiri, poyerekeza ndi gypsum zachilengedwe, gypsum desulfurized imakhala ndi zonyansa zambiri monga calcium sulfate hemihydrate, calcium carbonate, ndi silica.Izi zimakhudza mlingo wa hydration ndi kuchuluka kwa kutentha kwaiye pa anachita.The tinthu kukula ndi enieni padziko dera desulfurized gypsum zidzakhudzanso mlingo ndi mphamvu ya kutentha kwa hydration.Zing'onozing'ono particles ndi ikuluikulu yeniyeni padziko kuonjezera kukhudzana m'dera ndi atsogolere anachita, chifukwa mu kutentha kwa hydration.Madzi okhutira ndi kutentha kwa zinthu zingakhudzenso kutentha kwa hydration ndi kulamulira mlingo ndi mmene anachita.Kuchuluka kwa madzi ndi kutentha kochepa kumatha kuchepetsa kutentha ndi kutentha kwa hydration, pamene madzi otsika komanso kutentha kwapamwamba kungapangitse mlingo ndi mphamvu ya kutentha kwa hydration.Zowonjezera monga ma cellulose ethers zimatha kukhudza kutentha kwa hydration polumikizana ndi makristasi a gypsum ndikusintha katundu ndi machitidwe awo.
Ubwino wogwiritsa ntchito ma cellulose ethers kuti muchepetse kutentha kwa hydration ya gypsum desulfurized
Kugwiritsa ntchito kwathu ma cellulose ethers monga zowonjezera kuti muchepetse kutentha kwa hydration ya desulfurized gypsum kumapereka maubwino angapo, kuphatikiza:
1. Kupititsa patsogolo ntchito ndi kusasinthasintha kwa zipangizo, zomwe zimapindulitsa kusakaniza, kuyika ndi kukonza zinthu.
2. Kuchepetsa kufunikira kwa madzi ndikuwonjezera kusungunuka kwa zinthu, zomwe zimatha kusintha makina ndi magwiritsidwe ntchito azinthu.
3. Limbikitsani mphamvu yosungira madzi ndikuwonjezera nthawi ya madzi a zinthuzo, potero kuchepetsa kupsinjika kwa kutentha ndi kuchepa.
4. Kuchedwetsa gawo loyamba la hydration, kuchedwetsa nthawi yolimba ya zinthu, kuchepetsa mtengo wapamwamba wa kutentha kwa hydration, ndikuwongolera chitetezo ndi khalidwe la zipangizo.
5. Limbikitsani mphamvu zamakina ndi magwiridwe antchito azinthu, zomwe zitha kupititsa patsogolo kulimba, mphamvu ndi kukana kwazinthu.
6. Cellulose ether ndi yopanda poizoni, yowonongeka komanso yowonjezereka, yomwe ingachepetse kukhudzidwa kwa chilengedwe ndikulimbikitsa chitukuko chokhazikika cha zomangamanga.
Pomaliza
Ma cellulose ethers ndi zowonjezera zowonjezera zomwe zingakhudze hydration ndi kukhazikitsa njira za gypsum desiccated pokonza kugwirira ntchito, kusasinthasintha, kusunga madzi ndi makina azinthu.Kuyanjana pakati pa ma cellulose ethers ndi gypsum crystals kungachepetse kutentha kwakukulu kwa hydration ndikuchedwetsa nthawi yoikika, zomwe zingapangitse chitetezo ndi khalidwe la zinthuzo.Komabe, mphamvu ya cellulose ethers ingadalire zinthu monga mankhwala, kukula kwa tinthu, chinyezi, kutentha ndi zowonjezera zomwe zimagwiritsidwa ntchito pazinthuzo.Kafukufuku m'tsogolo ayenera kuganizira optimizing mlingo ndi chiphunzitso cha mapadi ethers kukwaniritsa kufunika kuchepetsa kutentha kwa hydration wa gypsum desulfurized popanda zimakhudza makina ake katundu ndi katundu.Kuonjezera apo, phindu lomwe lingakhalepo pazachuma, chilengedwe, ndi chikhalidwe cha anthu ogwiritsira ntchito ma cellulose ethers ayenera kuunikanso ndikuwunikiridwa.
