Pali zoperewera pakusintha kwa magwiridwe antchito gypsum slurry ndi mtundu umodzi. Kuti mukwaniritse matope okhutiritsa gypsum ndikumakumana ndi zofunikira zamankhwala, ma admictives mankhwala, ma adlectives ndi zida zosiyanasiyana amafunikira kuti azikhala ophatikizidwa komanso mwanzeru.
1 coagunt
Makina ogwiritsira ntchito amagawika makamaka ndi othamanga. M'matope a gypsum yowuma, zinthu zomwe zimapangidwa ndi pulasitala zonse zimagwiritsa ntchito pokonzanso ma sohydrite kapena mwachindunji matenda a disydrate gypsum imafuna kukhazikitsa.
2 wobwezererera
Kuonjezeranso zopumira kwa gypsum zouma zouma zouma zokuthandizani. Zinthu zokhudzana ndi ma hydration wa pulasitala wa Paris ndi zosiyanasiyana, kuphatikiza gawo la kapangidwe ka paris, kuphatikiza kwa tinthu tating'onoting'ono. Chilichonse chimakhala ndi mphamvu inayake panjira yobwereza, choncho kuchuluka kwa wobwezeretsa m'mikhalidwe yosiyanasiyana kumakhala kosiyana kwambiri. Pakadali pano, wobwezeretsera bwino kwambiri kwa gypsum ku China ndi mapuloteni a metamorphic (omwe ali ndi phindu la mtengo wotsika, nthawi yayitali yotayirira, yomanga bwino yogulitsa ndi nthawi yayitali. Pokonzekera la pansi-tracco gyplum, mlingo nthawi zambiri umakhala 0,06% mpaka 0.15%.
3 coagulant
Kuthamangitsa nthawi yosangalatsa ya slurry ndikupitilira liwiro losangalatsa la slirry ndi njira zonse zogwirizira thupi. Mankhwala ophatikizika omwe amagwiritsidwapo ntchito pazomangira zomangira a boydrate ufa umaphatikizira potaziyamu chloride, vastavin slika matering, sulfate ndi ma acid ndi acids ena. Mlingo nthawi zambiri umakhala 0,2% mpaka 0.4%.
4 Wosunga madzi 4
Gypsum zouma zouma zosakanikirana ndizosagwirizana ndi othandizira osunga madzi. Kupititsa patsogolo madzi osunga madzi a gypsum pr slurry ndikuwonetsetsa kuti madziwo akhoza kukhalapo mu gypsum slurry kwa nthawi yayitali, kuti athe kupeza mankhwala abwino. Kuwongolera kugwirira ntchito kwa gypsum ufa, kuchepetsa ndi kupewa magazi a gypsum, ndikusinthana ndi nthawi yotseguka, ndikusinthanso kwa masitolo apamwamba ngati osakanizidwa ndi othandizira madzi. Kaya wosunga madzi wosungidwa ndi wabwino amatengera kuperekera, kusungunuka nthawi yomweyo, kukhazikika, kukhazikika kwa matenthedwe ndi kukula kwamphamvu kwambiri.
① Mtumiki wololera wa cellulose
Pakadali pano, zogwiritsidwa ntchito kwambiri pamsika ndi hydroxypropyl methy cellulose, kenako pathyl cellulose, kenako carboxymethyl cellulose. Kugwirira ntchito kokwanira kwa hydroxypropyl meth cellose ndiyabwino kuposa ya methyl cellulose, ndipo kuchuluka kwa madzi ndi okwera kuposa a carboxymethyl. Mu zomangira gypsum zouma zouma, mlingo wa hydroxypyl ndi methyl cellulose nthawi zambiri imakhala 0,1%, ndi mlingo wa carboxymethyl cellose ndi 00%. Zatsimikiziridwa ndi kuchuluka kwakukulu kwa zitsanzo zofunsira kuti kuphatikiza awiriwo ndikwabwino. .
Mtumiki wa ②stiarch
Wogwiritsa ntchito madzi wopukutira amagwiritsidwa ntchito makamaka kwa gypsum putty ndi gypsum yoyala, ndipo amatha kusintha mbali kapena kuchuluka kwa mankhwala a cellulose. Kuonjezera munthu wopukutira madzi opukutira kwa gypsum youma ufa ufa ukhoza kusintha kugwirira ntchito, kugwirira ntchito komanso kusasinthika kwa slurry. Zojambula zochulukirapo pamadzi osungirako zimaphatikizapo tapioca startary, batalatinatinated starch, carboxypropyl owuma, ogulitsa nthawi zambiri amakhala 0,3% mpaka 1% mpaka 1%. Ngati mlingo wake ndi waukulu kwambiri, chinthu cha gypsum chizikhala chofewa m'malo chinyezi, chomwe chidzakhudza ntchitoyo.
③glue mtundu wamadzi
Azichete ena akunthawi yomweyo amathanso kukhala ndi gawo labwino pakusungidwa kwamadzi. Mwachitsanzo, 17-88, 24-88 Polyvinyl mowa ufa ndi chingamu ndipo guar chingamu chimagwiritsidwa ntchito ku Gypsum Storts olemera monga gypsum stety, ndi gypsum mafuta otchinga. Mlingo wa mankhwala osungira ma cellulose amatha kuchepetsedwa. Makamaka mu gypsum gypsum yolumikizira, nthawi zina, imatha kusintha teleli elefase.
④norganic madzi osungira
Kugwiritsa ntchito zida zina zosungidwa m'madzi mu gypsum zouma zouma zimatha kuchepetsa kuchuluka kwa zida zina zosungika, kuchepetsa ndalama zina, komanso kusewera ndi gawo lina pakuwongolera kugwirira ntchito ndi gypsum slurry. Zida zosungiramo zachilengedwe zambiri zimakhala bentonite, kaolin, diatomite, wofatsa ufa, ufa wa Perlite, dongo la Atlite, etc.
5
Kugwiritsa ntchito zomatira ku gypsum zouma zouma zouma ndi chachiwiri kokha kwa othandizira ndi ogulitsa. Gypsum yokhayokha yodzilimbitsa, yolumikizira gypsum, gypsum gypsum, ndi mafuta otenthetsera matenda a gypsum ndi osagwirizana ndi zomatira.
Anatulika Polymer ufa:
Kubwezeretsedwanso ufa wa latx kumagwiritsidwa ntchito kwambiri mu matope a gypsum, gypsum the matope okhazikika, makamaka mu matope a gypsum, ndikupanganso magazi, ndikupewa magazi, komanso kusintha magazi. Mlingo nthawi zambiri umakhala 1.2% mpaka 2.5%.
Kuledzera kwa Polyvinyl:
Pakadali pano, mowa womwe umagwiritsidwa ntchito kwambiri polyvinyl pamsika ndi zochitika 24-88, zomwe zimagwiritsidwa ntchito popanga gypsum, gypsum amapanga ma gypsum ndi zinthu zina. 0.4% mpaka 1.2%.
Guar Gum, Tian Ring Gum, Carboxymethyl cellulose, ether ether ethelose, etc. Kodi zomatira zonse ndi zida zosakanikirana zouma.
6 Thickener
Kukula kumathandiza makamaka kukonza kugwirira ntchito ndi sags ya gypsum slorry, yomwe ili yofanana ndi zomatira ndi othandizira osungira madzi, koma osakhalatu. Zogulitsa zina za thickener ndizothandiza pakukula, koma osati yabwino pankhani ya chikolowero ndi kusungidwa kwamadzi. Mukamakonzekera gypsumbu youma ufa wa ufa, gawo lalikulu la ovomerezeka liyenera kulingaliridwa kwathunthu kuti lizikhala bwino komanso kugwirizanitsa akwati. Zogulitsa zochulukirapo ndi polyacrylamide, tian quing, guar chingamu, carboxymethyl cellulose, etc.
Mtumiki 7 wokhala ndi mpweya
Othandizira ndege, omwe amadziwikanso kuti wothandizirana nawo, amagwiritsidwa ntchito makamaka pazomangira zouma zouma monga gypsum thermit ndi gypsum. Wothandizira wa mpweya (wothandizirana) amathandizira kukonza kugwirira ntchito, kusokonezeka, kukana chisanu, ndikuchepetsa magazi ndi tsankho. Mlingo nthawi zambiri umakhala 0,01% mpaka 0.02%.
8 decomers
Defotanta nthawi zambiri amagwiritsidwa ntchito ku gypsum yokhayokha yodzilimbitsa komanso gypsum yolimba, yomwe imatha kusintha kachulukidwe, mphamvu, madzi kukana ndi mgwirizano wa kusalala. Mlingo nthawi zambiri umakhala 0,02% mpaka 0.04%.
9 Kuchepetsa Madzi
Madzi ochepetsa thupi amatha kusintha madzi a gypsum slurry ndi mphamvu ya gypsum yolimba thupi, ndipo nthawi zambiri amagwiritsidwa ntchito kwa gypsum okha ndikuwonetsa gypsum. Pakadali pano, zapamwamba zapamwamba zimakonzedwa molingana ndi madzi ndi nyonga: Polycamoxylate repoalicises, SuperPlasticsticastic, reaclasulicstigrizer, ndi Limsulfonate SuperPlasticizer. Mukamagwiritsa ntchito kuchepa kwa madzi mu zida zomangira gypsum zouma zouma, kuwonjezera pa kulingalira madzi ndi mphamvu, chidwi chiyeneranso kulipidwa kwa nthawi ndi madzi omanga gypsum pakapita nthawi.

Chitsime chachikulu kwambiri cha zinthu gypsum ndi madzi osakanizika, ndipo madzi kukana kwa gypsum youma-yosakanikirana ndi pamwamba madera okhala ndi chinyezi chambiri. Nthawi zambiri, madzi kukana matenda a gypsum yolimba amayenda bwino powonjezera ma hydraul osakaniza. Pankhani ya madzi onyowa kapena okwanira, kuphatikiza kwina kwa hydraulic kumatha kupanga zokongoletsera za gypsum zomwe zimakhazikika. Mankhwala othandizira amathanso kugwiritsidwa ntchito kuti muchepetse kusungunuka kwa gypsum (ndiye kuti, kuchepetsa kuchuluka kwa gypsum yolimba (ndiye kuti, njira yopanda madzi yodzipatula). Malonda a gypsum amawaphatikiza a ammonium borate, sodium methylsiliconate, silika uled, emulsied paraffin, ndi silika emulsion orproousming othandizira.
11 Olimbikitsa Ogwira Ntchito
Kuyambitsa anhyrite wachilengedwe komanso mankhwala kumapangitsa kuti ukhale womata komanso wamphamvu, woyenera kupanga zida zomangira gypsum. Ogwira ntchito ya asidi amatha kuwonjezera kuchuluka koyambirira kwa anhyrite ,fupifupi ndi nthawi yokhazikika, ndikusintha mphamvu yoyambirira ya gypsum yolimba. Wogwira ntchito ya alkaline sathandiza pang'ono kuchuluka kwa anhyrite, koma amatha kupanga zida zolimba za gypsum zolimba, ndipo zimatha kupanga zida zolimba kwambiri. Kugonana. Mphamvu ya acid-base Harectogrator ndibwino kuposa ya asidi imodzi kapena alkaline. Zolimbikitsa acid zimaphatikizapo potaziyamu Alum, sodium sulfate, potaziyamu sulfate, etc.
Mafuta a thixotropic
Mafuta a thixotropic amagwiritsidwa ntchito podzipangitsa gypsum kapena gypsim, zomwe zimachepetsa matope a gypsum, ndikuchepetsa nthawi yayitali, kuti malo otsekemera atha kupeza mkaka wabwino. Kapangidwe ka thupi ndi yunifolomu powonjezera mphamvu zake
