Umunyasizi, Gypsum ni gaze yimbuto iterwa no guswera kirimo sulfuru (amakara, peteroli), patipsumu ya hemih · ya Gypsum. Kubwibyo, hariho ubushakashatsi bwinshi kandi busaba gukoresha Gypsusud Gypsusud Gypsum aho kuba Gypsum karemano kubyara ibikoresho byo kwishyira hejuru. Organic Polymer AdMaltures nko kugabanya amazi, amazi agumana umukozi na redirri nibice byingenzi bigize ibikoresho byo kwishyira hamwe. Imikoranire nuburyo bubiri hamwe nibikoresho bimennye nibibazo bikwiye kwitabwaho. Bitewe nibiranga uburyo bwo gushinga, igorofa ya Gypsum yateye ubwoba ni nto (ingano ya 6 na 60), kandi imitungo yifu idahwitse, bityo rero imitungo ya Ghepsusum yababaje, na minisiteri Gutandukana byateguwe nabyo birahari byoroshye gutandukana, gushishikarira no kuva amaraso bibaho. Uburenganzira bwa Cellulose nicyo gikunze gukoreshwa cyane muri minisiteri, kandi ikoreshwa ryakozwe namazi nicyemezo cyingenzi cyo kumenya imikorere yuzuye gypsusum yishyirahamwe ryubwubatsi nko kwishyira hamwe nubwubatsi na nyuma yimikorere yubukanishi na nyuma yubuka bukanishi.
Muri iyi mpapuro, agaciro k'amazi gakoreshwa nkigipimo cyo kugenzura (gukwirakwiza impamyabumenyi ya 145 mm), kwibanda ku ngaruka zibiri muri selile hamwe no gukoresha amazi ya gypsusur. -Gutanga ibikoresho, gutakaza amazi mugihe, no gusezera amategeko yingaruka mugihe cyibanze hamwe nubukanishi bwa mbere; Muri icyo gihe, ku ngoma Amategeko yo kugira ingaruka kuri selile ether ku bushyuhe no gukusanya ubushyuhe bwa Sypsum ya Gypsisum ya Sypsiade ya Sypsiade ya Sypsiure ya Cypsusus hamwe na sisitemu ya Gypsumu .
1.. Ibikoresho bya Raw hamwe nuburyo bwo kwipimisha
1.1 Ibikoresho fatizo
Ifu ya Gypsum: Ifu ya Gypsum yiboneye na sosiyete i Tangshan, ibihangano nyamukuru ni hempsiation gypsiation, bigaragazwa mu mbonerahamwe ya 1, kandi imitungo yayo irerekanwa mu mbonerahamwe ya 2.
ishusho
ishusho
Ibikoresho birimo: Ubugari bwa Cellulose (HydroxyPropyl Methylcellse, HPMC kuri make); superphicestizer wr; deifoamer b-1; Eva yongeye kuvugurura ifu ya latex s-05, byose bihari mubucuruzi.
Igiteranyo: Umucanga Kamere, umucanga mwiza watanze unyuze kuri mm 0,6.
1.2 Uburyo bw'ikizamini
SWALFFURIATION YAHAWE GALPSUEST: Umucanga: Amazi = 1: 0.45, Ubworoherane Bm 55 MM ) 0, 0.5 ‰, 1.0 ‰, 2.0 ‰, 3.0 ‰ etherlealilose ether (HPMC-20.000); Ikindi gukosora igipimo cya selile ether kugeza 1 ‰, hitamo HPMC-20.000, HPMC-40.000 ) Gypsusud Gypsum yohererezanyaga uruvange rwubwoko bwaganiriweho. Uburyo bwihariye bwikizamini bukorwa hakurikijwe ibisabwa na GB / T 17669.3-1999 "kugena imiterere ya mashini yo kubaka Gypsum".
Ubushyuhe bwikizamini cya Hydration burakorwa hakoreshejwe urugero rwa Gypsum ya Deulfurire yicyiciro cya kabiri cya 0.5 ‰ na 3 ‰, kandi igikoresho cyakoreshejwe ni ubwoko bwikirere.
2. Ibisubizo nisesengura
2.1 Ingaruka za selile zirimo ibintu byibanze bya minisiteri
Hamwe no kwiyongera kw'ibirimo, imikorere n'ubuhuze bwa minisiteri biratera imbere cyane, gutakaza amazi mugihe bikabije, kandi imikorere yubwubatsi irakomeye, kandi minisiteri ikomantaje nta gitanda, nubusanzure, Kwiyoroshya na aesthetics byatejwe imbere cyane. Muri icyo gihe, gukoresha amazi ya minisiteri kugirango tugere ku mazi amwe yiyongereye cyane. Kuri 5 ‰, gukoresha amazi byiyongereyeho 102%, kandi igihe cyanyuma cyo gufungwa cyarafunzwe na min 100, cyari inshuro 2,5 zicyitegererezo cyuzuye. Imitungo yakabuka ya minisiteri yagabanutse cyane hamwe no kongera ibikubiye muri selile. Iyo ibikubiye muri selile byari 5 ‰, imbaraga 24 z imbyazi 24 froxiving yagabanutse kugera 18.75% na 11.29% byicyitegererezo cya ubusa. Imbaraga zo gutuza ni 39.47% na 23.45% byicyitegererezo cyambaye ubusa. Birakwiye ko tumenya ko kwiyongera k'umukozi ugumana amazi, ubucucike bukabije bwa minisiteri nabwo bwagabanutse cyane, kuva kuri 2069 kg / m3 kuri 5 kugeza 5 ‰, kugabanuka kwa 15.56%. Ubucucike bwa minisiteri bugabanuka kandi uburozi bwiyongera, bukaba ari bumwe mu mpamvu zitera kugabanuka kugaragara muburyo bwa minishi.
Ubugari bwa selile ni polymer itari polymer. Amatsinda ya hydroxyl kumurongo wa selile na atome ya ogisijeni kuri bond ya ether irashobora guhuza na molekile y'amazi, bityo agira uruhare mu mazi yiherereye, bityo agira uruhare mu mazi adahuje amazi. Ibiro bya macroskopilitike bigaragarira nkubwiyongere bwubumwe bwa slurry [5]. Ubwiyonzo bworoshye bwo kunyerera ntabwo buzamura amazi gusa, ariko kandi ubumwe bwakagari byaciwe ku buso bwa gypsim, bibangamira imyitwarire yo gukumira no kubuza igihe cyo gushiraho; Mugihe cyo kubyutsa, umubare munini wo mu kirere na we uzatangizwa. Imirasire izashyiraho nka minisiteri ikomeye, amaherezo igabanya imbaraga za minisiteri. Ku buryo bumva ushishikajwe no gukoresha amazi adashyize ahagaragara, imikorere yubwubatsi, igena igihe na kaburimbo, nibindi, ibikubiye muri selile muri minisiteri yo kwiheba.
2.2 Ingaruka zuburemere bwa molekile ya selile ether kumikorere ya minisiteri
Mubisanzwe, hejuru cyane viscosiya nibyiza byiza bya selile, niko kugumana amazi no kongera imbaraga zo guhuza. Imikorere izagira ingaruka mbi. Kubwibyo, ingaruka za selile yuburemere butandukanye bwa molekari kumitungo yibanze ya Gypsum ishingiye kuri minisiteri ishingiye kuri minisiteri yageragejwe. Amazi ya MURER yiyongereye ku rugero runaka, ariko nta ngaruka bigaragara yari afite mugihe cyo gushinga no kwerekana amazi. Muri icyo gihe, imbaraga za minisiteri kandi zitera minisiteri muri leta zitandukanye zerekanaga inzira yo hepfo, ariko kugabanuka ntibyari bifite ingaruka za selile ya ether kumurongo. Muri make, ubwiyongere bwuburemere bwa kalliolose bwa selile nta ngaruka zigaragara nta ngaruka zigaragara nta ngaruka zigaragara nta ngaruka zigaragara ku mikorere ya minisiteri. Urebye korohereza kubaka, ubushyuhe buke na molekular-uburemere bwa selile-uburemere bugomba gutoranywa nkuko ibikoresho byo kwihesha agaciro.
2.3 Ingaruka za selile ether ku bushyuhe bwa hydration ya gypsumus despsumu
Hamwe no kwiyongera kubiri muri selile ether, impinga ya Ethermic ya Hydration ya Gypsid ya buhoro buhoro yagabanutse buhoro buhoro, kandi igihe cyo kurengana cyatinze gato, mugihe ubushyuhe bwa lydration bwatinze, ariko mugihe ubushyuhe bwa hydrat bwatinze, ariko buragaragara. Ibi byerekana ko ether ya selile ishobora gutinza igipimo cyimiterere ya hydration hamwe na sypretion ya gypsumu yiboneye kurwego runaka, bityo dosage ntigomba kuba nini cyane, kandi igomba kugenzurwa muri 1 ‰. Birashobora kugaragara ko firime ya colloidal yashizweho nyuma yubumwe bwa selile iterana amazi ahimbaza hejuru ya gypsum ibice bya gypsum, bigabanya igipimo cyimikino ngororamubiri mbere ya 2 h. Muri icyo gihe, kugumana amazi adasanzwe kandi ingaruka zijimye zidindiza guhumeka amazi no gutandukana bifitiye akamaro ko hirya no hino ya gypsim yinjiye mu cyiciro cya GPESURIES. Muri make, mugihe dosiye ikwiye igenzurwa, ether ether ifite uruhare runini ku gipimo cya hydration hamwe na Hydration Strast ya Gypsum yibasiye ubwato. Muri icyo gihe, kwiyongera kwa selile ether hamwe nuburemere bwa molekile bizamura cyane viscolity yo gutandukana no kwerekana imikorere yo kugumana amazi meza. Kugirango umenye amazi ya Gypsusud yishyure kuri minisiteri, ibiryo byamazi bizongera kwiyongera cyane, bikaba biterwa nigihe kirekire cya minisiteri. Impamvu nyamukuru yo kugabanuka mubikorwa bya mashini.
3. UMWANZURO
. Ugereranije nibikubiyemo, uburemere bwa molekile ya selile birahuza ubwiyongere bufite mumitungo yavuzwe haruguru ya minisiteri. Urebye ku buryo bumva neza, ether ether igomba gutoranywa n'uburemere buto bw'intego (urugero rwa vino iri munsi ya 20 000 Pa · s), kandi igipimo kigomba kugenzurwa muri 1 000 Pas), kandi igipimo kigomba kugenzurwa muri 1 ‰ y'ibikoresho bikozwe mu gihirahiro.
. Ubwiyongere bwo kunywa n'amazi no kugabanuka kwamavuza ubwinshi nimpamvu nyamukuru zo kugabanuka mumitungo ya mashini ishingiye kuri gypsumu.
