Kodi ndi gawo lanji la madzi omwe amasungidwa ndi gypsum ufa?
Yankho: Kupaka gypsum, gypsum gypsum, gypsum gypsum, gypsum putty ndi zinthu zina zomanga zimagwiritsidwa ntchito. Pofuna kuwongolera zomangamanga, ogula gypsum amawonjezeredwa pakupanga nthawi yomanga yomanga kwa gypsum slorry. Wogulitsa amawonjezeredwa kuti alepheretse matenda a hemihydrate gypsum. Mtundu wa gypsum slurry umayenera kusungidwa khoma 1 mpaka 2 maola chisanachoke Zipangizo za khoma, kotero kuti gypsum slurry iyenera kukhala madzi osungidwa kuti mupewe gawo lamadzi kuti asamukire kukhomalo, zomwe zimapangitsa kuperewera kwamadzi pomwe ma hydram. Kwathunthu, ndikupangitsa kulekanitsidwa ndi kuwiritsa kwa cholumikizira pakati pa pulasitala ndi khoma. Kuphatikiza kwa wothandizila kwa madzi ndikusunga chinyezi chokhala ndi gypsum slurry, kuonetsetsa kuti ma hydram omwe amasankha gypsum pa mawonekedwe, kuti atsimikizire kuti pali mphamvu. Othandizira osungidwa m'madzi omwe amakhala ndi cellouse, monga: Methyl cellulose (hertroxypyl (heldrox), sodium yosinthika, Zochitika zapadziko lapansi, etc. zitha kugwiritsidwanso ntchito kukonza magwiridwe antchito.
Ziribe kanthu kuti ndi mtundu wanji wambiri womwe ungachedwetse madzi a hypsum kuti muchepetse gypsum yosiyanasiyana, pomwe kuchuluka kwa wobwezeretsa sikunasinthe, komwe kumasungidwa kwa madzi kumatha kubweza kwa mphindi 15-30. Chifukwa chake, kuchuluka kwa wobwezeretsa kumatha kuchepetsedwa moyenerera.
Kodi mlingo woyenera wa madzi wosunga ufa wa gypsum ufa ndi uti?
Yankho: Othandizira osungira madzi nthawi zambiri amagwiritsidwa ntchito popanga ufa wopanga gypsum, yolumikizana ndi gypsum, yolowera gypsum, ndi gypsum. Chifukwa mtundu wa gypsum uwu umasakanikirana ndi wobwezeretsera, zomwe zimalepheretsa ku gysuhydrate gypsum slurry kuti muchepetse gawo la madzi Kuperewera kwa madzi ndi hydration osakwanira pomwe gypsum slurry imawuma. Kuphatikiza kwa wothandizila kwa madzi ndikusunga chinyezi chokhala ndi gypsum slurry, kuonetsetsa kuti ma hydram omwe amasankha gypsum pa mawonekedwe, kuti atsimikizire kuti pali mphamvu.
Mlingo wake nthawi zambiri umakhala 0.1% mpaka 0.2% (yowerengera gypsum), pamene gypsum slurry imagwiritsidwa ntchito makoma a gypsim, makoma a njerwa, ndi zina zopindika Gypsum, gypsum gypsum, gypsing gypsim kapena malo opyapyala, kuchuluka kwa wothandizira madzi kumafunikira kukhala akulu (nthawi zambiri 0,5%).
Mankhwala osunga madzi monga methyl cellulose (Mc) ndi Hydroxypylloull (HPMC) ndi osungunuka, koma adzasungunuka munthawi yoyamba ikasungunuka m'madzi. Wogulitsa madzi amafunikira kusakanikirana ndi gypsum ufa wobalalitsidwa. Konzekerani kukhala ufa wouma; Onjezani madzi ndikuyambitsa, lolani kuti ayime kwa mphindi 5, kukhazikika, zotsatira zake zimakhala bwino. Komabe, pakadali pano pakali pano pakompyuta yomwe imatha kusungunuka mwachindunji m'madzi, koma samalimbikitsa pang'ono kupanga matope a ufa.
Kodi wothandizira mankhwalawa amasewera bwanji madzi owombera gypsum?
Yankho: Mitundu yosiyanasiyana ya othandizira madzi amagwira ntchito mu gypsum yolimba kwambiri malinga ndi mitundu yosiyanasiyana yochita. Kwenikweni zitha kufotokozedwa mwachidule mu njira zinayi izi:
. Mwachitsanzo, kupangira mafuta acid ndi acid okhala ndi C7-C9 kumawonjezeredwa, ndipo kuchuluka koyenera kwa ma ammonium ndi ammonium amawonjezeredwa nthawi yomweyo.
. Mwachitsanzo, kuphatikiza parafini emulsion, asphal emulsion ndi paraffin-rosin emulsite emulsion emulsion, emu adakonza emulsite Emulsion, etc.
. Mwachitsanzo, madzi osiyanasiyana a Silicone amaphatikizidwa, kuphatikiza mafuta osiyanasiyana amiyala.
. Zosasinthika zosungunulira ndizabwino kuposa silikambole zokhazikitsidwa ndi madzi, koma zakale zimapangitsa kuti mpweya ukhale wa gypsum wokhazikika.
Ngakhale othandizira osiyanasiyana amatha kugwiritsidwa ntchito kukonza zida zomangira za gypsum mosiyanasiyana, gypsum akadali ndi malo owombera mpweya, omwe sioyenera ku malo otetezeka zonyowa komanso zowuma.
Kodi kusintha kwa gypsum yomanga ndi mankhwala?
Yankho: Pali njira ziwiri zazikulu zopangira gypsum Waterproous: imodzi ndikuwonjezera kalozera wofewa pochepetsa kusungunuka, ndipo winayo ndikuchepetsa njira zoyamwa madzi. Ndipo kuchepetsa mitundu yamadzi kumatha kuchitika kuchokera pawiri. Chimodzi ndikuwonjezera chipilala cha gypsum grapsum, ndiye kuti, kuchepetsa madzi a gypsum mwa kusokoneza khungu ndi ming'alu yazida, kuti yopititsa patsogolo madzi a gypsum. Wina ndikuwonjezera mphamvu ya gypsum yolimba thupi, ndiye kuti, kuchepetsa madzi okonda gypsum popanga mawonekedwe apakati pa filimu ya Hydrophobic.
Othandizira madzi omwe amachepetsa chidwi amatenga gawo poletsa ma pores abwino a gypsum ndikuwonjezera mphamvu ya thupi la gypsum. Pali ma Adminix ambiri okhwima, monga: Parafin emulsion, asphal emulsion, rosin emulsion ndi parafini phula lopanga emulsion. Othandizira madziwa ndi othandiza pochepetsa chidwi cha gypsum mu njira zoyenera kusinthira, koma nthawi yomweyo, amakhalanso ndi zovuta zina pa gypsum.
Makina owoneka bwino kwambiri omwe amasintha mphamvu yapamwamba ndi silika. Itha kulowera padoko lililonse, sinthani mphamvu zapamwamba mkati mwa kutalika kwake, ndikusintha mabowo, ndikupangitsa mamolekyulu amadzi kuti apangitse mabela, kuti akwaniritse cholinga cha madzi, Ndipo nthawi yomweyo amakhalabe ndi mpweya wa pulasitala. Zosiyanasiyana za mtundu wamtunduwu makamaka wothandizirana makamaka: sodium mediconute, silikaudenti wa siliclated, omwe amathandizira kuti ma pores asakhale akulu kwambiri, ndipo nthawi yomweyo sakanakana Kulowetsedwa kwa madzi opanikizika, ndipo sangathetsetsenso zovuta zam'madzi zazitali ndi chinyezi cha zinthu zama gypsum.
Ofufuzawo amagwiritsa ntchito njira yophatikiza zinthu zachilengedwe ndi zopangira, ndiye kuti, kutengera mowa wa emulfion uldeyl wothandizira amapangidwa ndi kuphatikiza mchere wothandizira mchere. The Gypsum amapanga mankhwala osakanikirana amatha kusakanizidwa mwachindunji ndi gypsum ndi madzi, kutenga nawo gawo pa grypslunthution ya gypsum, ndipo pezani bwino madzi.
Kodi zotsatira za kuyika za Silane Marketproofroofroofroofroofroofroofroofroofroofroofroofroofroofroofceofroofroofceofroofceofroofroofroofroous wothandizira ku gypsum?
Yankho: Mphamvu ya Oletsa ya Silane pa 0.4% Silane ndi yabwino, ndipo mphamvu zake zolepheretsa zimakhazikika pomwe kuchuluka kwake kumapitilira kuchuluka kwake.
