Gypsumuss Gypsum ni inganda Gypsum yabonetse mugutera imbaraga zoroshye kandi koza gaze yakozwe nyuma yo gutwikwa na lisansi ya sulfur ukoresheje lime nziza cyangwa ifu yubutaka bwiza. Ibigize imiti ni kimwe na gypsum ya siyderate isanzwe, cyane cyane caso4 · 2h2o. Kugeza ubu, igihugu cyanjye cy'igihugu cyanjye kiracyaganjemo imbaraga zarashwe n'amakara, kandi ubushyuhe bwasohoye mu gihe cy'ibihugu by'ibihugu birenga 50%. Umubare munini wa dioxyde ya dioxyde yateje umwanda ukomeye mubidukikije. Gukoresha Ikoranabuhanga rya gaze ya Flue kugirango tubyare Gypsusum yateye imbere ni igipimo cyingenzi cyo gukemura iterambere ryikoranabuhanga ryinganda zijyanye namakara. Nk'uko imibare ituzuye, gypsisum yatose itose mu gihugu cyanjye yarenze miliyoni 90 t / a, n'uburyo bwo gutunganya Sypsumu bwuzuyemo cyane cyane, ariko bikatera gutakaza ubutaka.
Gypsum ifite imirimo yuburemere bwumucyo, kugabanya urusaku, gukumira umuriro, ibipimo byumuriro, nibindi birashobora gukoreshwa mubyasaruro bya sima, umusaruro wa Gysum, Ubwubatsi hamwe nizindi nzego. Kugeza ubu, intiti nyinshi zakoze ubushakashatsi kuri plaster. Ubushakashatsi bwerekana ko ibintu bya plaster bihindura micro-playsion, ibikorwa byiza na plastike, kandi birashobora gusimbuza ibikoresho gakondo byo gushushanya urukuta rwa musoor. Ubushakashatsi bwanditswe na XU JianJun nabandi bagaragaje ko Gypsusud Gypsum yakoreshwaga kugirango habeho ibikoresho byo kuvura. Ubushakashatsi bwawe Beihong nabandi bagaragaje ko Gypsim yakozwe na Gypsusud yakozwe mu rukuta rw'imbere rw'urukuta rw'imbere, urukuta rw'imbere, kandi rushobora gukemura ibibazo rusange nko kurandura burundu. Gypsum yoroheje ya plassitin nubundi bwoko bushya bwibidukikije. Ikozwe muri hemihpram gypsum nkimikorere nyamukuru yongeyeho yongeraho igiteranyo no kumvikana. Ugereranije nibikoresho gakondo bya sima, ntabwo byoroshye guca, gukomera, kugabanuka kw'ibinyabuzima, icyatsi kibisi no kurengera ibidukikije. Gukoresha Gypsusud ya Gypsusum yoroshye kubyara hemihydrate gypsum gusa kugirango ikibazo kibuze umutungo kavukire gakondo, ariko kandi umenya ibikoresho byumutungo wa Gypsumu, ariko bikamenya ibikoresho by'Umutungo wa Sypsusum ya Gypsusum ya Dypsusum kandi bigera ku ntego yo kurinda ibidukikije. Kubwibyo, ukurikije ubushakashatsi bwa Gypsum yateye imbere, iyi mpapuro igerageza igihe cyo gushiraho, imbaraga zoroheje nimbaraga zifatika zo guteza imbere uburemere bwa Gypsusu.
Ubushakashatsi 1
1.1 Ibikoresho fatizo
Desfurulation ifu: Hemihdrate Gypsum yakozwe kandi akabarwa nikoranabuhanga rya gazi yisumbuye, agaragara mu mbonerahamwe ya 4%, 8%. Mypsum Fartar.
Umucuruzi: Koresha sodium citrate, isesengura rya shimi rishingiye ku gipimo cyibiro byihuta cya plasstersing plasstersing destar, kandi ikigereranyo cyo kuvanga ni 0, 0,1%, 0.2%, 0.3%.
Cellulose Ether: Koresha HydroxyPropyl Methylcellse (HPMC), HPMC ishingiye kuri 400, HPMC ishingiye ku kigereranyo cy'uburemere Gypsusus Pertar Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastal Plastan
1.2 Uburyo bw'ikizamini
Kunywa amazi no gushiraho igihe cyo guhuza ibipimo ngenderwaho bya Gypsusum bivuga GB / T17669.4-1999 "kugena imiterere yumubiri wa GBPSUS Plaster", kandi igihe cyo gushushanya cya plaster deska "bikubiyemo" gushinga sypsum ".
Imbaraga za Flexiure kandi zikuramo zikorwa ukurikije GB / T9776-2008 "Kubaka Gypsum", hamwe ningendo zifite ubunini bwa 40mm × 40mm × 40mm × 16mm × 16mm × 16mm × 16mm hamwe nimbaraga za 2h hamwe nimbaraga za 2h hamwe nimbaraga za 2h hamwe nimbaraga za 2h hamwe nimbaraga za 2h hamwe nimbaraga za 2h hamwe nimbaraga za 2h hamwe nimbaraga za 2h hamwe nimbaraga za 2h. Imbaraga zihinduka kandi zitemba zuburemere bwa Gypsusud Parkan ikorerwa GB / T 28627-2012 "Gysingi ya POSPSUM", n'imbaraga zo gukira bisanzwe kuri 1D na 28D bipimwa.
Ibisubizo 2 n'ibiganiro
2.1 Ingaruka z'ifu ya Gypsum ku miterere ya mashini ya plasstertight Paluring Gypsum
Ingano yose yifu ya Gypsum, ifu ya hekede kandi yoroheje yoroheje ni 100%, hamwe nubunini bwumucyo uhamye kandi uhagurutse ntigihinduka. Iyo umubare w'ifu ya Gypsum ari 60%, 70%, 80%, na 90%, utera imbaraga ibisubizo bya farux hall kandi bitera minisiteri.
Imbaraga zoroheje nimbaraga zo kwikuramo urumuri rwinshi gypsusud bombi biyongereyeho imyaka, byerekana ko urwego rwimikino rwa Gypsim ruhagije hamwe nimyaka. Hamwe no kongera ifu ya Gypsum yishyize mu gaciro, imbaraga zoroheje n'imbaraga zo kwikuramo gypsium zoroshye zagaragaje muri rusange, ariko ubwiyongere bwari buto, kandi imbaraga zo kwiyongera ku minsi 28 zaragaragaye cyane. Ku myaka ya 1d, imbaraga zoroheje zoroheje zivanze na 90% ziyongereyeho 10.3% zagereranijwe na 60% ifu ya Gypsim, hamwe nimbaraga zifatanije ziyongereyeho 10.1%. Mfite imyaka 28, imbaraga zoroheje zoroheje zivanga na 90% ziyongereyeho 8.8% zijyanye n'iy'ifu ya Gypsum ivanze na 60%, hamwe n'imbaraga zifatanije ziyongereyeho 2,6%. Muri make, birashobora kwemeza ko ingano yifu ya Gypsum ifite ingaruka nyinshi ku mbaraga zihindagurika kuruta imbaraga zo kwikuramo.
2.2 Ingaruka zo Kuvunika Ibirindiza Kumurongo wa Manicalicre Yubwinshi Byuzuye Gypsusum
Umubare wuzuye wa gypsum, ifu ya hekede hamwe noroheje hamwe ni 100%, hamwe nubunini bwa Gypsum ihamye ya gypsum no kugenerwa ibisanzwe ntibihinduka. Iyo umubare wa microbead wahinduwe ari 4%, 8%, 12%, na 16%, umucyo wa plaster ibisubizo byimbaraga za gypsusul na minisiteri.
Mfite imyaka ingahe, imbaraga zoroheje nimbaraga zo guturika zumucyo wa PASTATU PRITATU YAGARAGARA MU MUNTU GYPSUS yagabanutse hamwe no kongera ibiri muri microbeds ya vitri. Ibi ni ukubera ko ibyinshi muri microbeds yashyizeho ibishoboka byose bifite ishingiro imbere n'imbaraga zabo ni bike, bigabanya imbaraga zoroheje kandi zitesha agaciro minisiteri yoroheje gypsight gypsum. Ku myaka ya 1d, imbaraga zoroheje zoroheje za kabiri za Gypsum zagabanutseho 35.3% ugereranije nifu ya gypsum 4%, hamwe nimbaraga zijyanye na 16% zagabanutseho 16.3%. Mfite imyaka 28, imbaraga zoroheje zoroheje zagabanijwe na 24.6% ugereranije n'iy'ifu ya gypsum 4%, mu gihe imbaraga zo kwikuramo zagabanutseho 6.0%. Muri make, birashobora kwemeza ko ingaruka zibirimo ibikubiye microbead imiterere yashizweho ku mbaraga zoroheje zirenze iyo mbaraga zikamba.
2.3 Ingaruka zo Gusubiramo Ibirimo Kugena Igihe cyumucyo Pypsum
Igipimo cyose cya Gypsum ifu, ifu ya hekede kandi yoroheje ni 100%, hamwe na dosage yifu ya gypsum, ifu ya hekes, eretine, ethertight na selile ether ikomeje. Iyo igipimo cya sodium ari 0, 0.1%, 0.2%, 0.3%, Gushiraho Igihe Ibisubizo byumucyo PASTATU PRITAS MISTAM.
Igenamigambi ryambere nigihe cyanyuma cyo kwerekana urumuri Dapsusud Faster Fariran ya Pyssisum Byombi Byiyongera Ibikomoka kuri sodium ibidukikije, ariko igihe cyo gushyiraho ni gito. Iyo sodiyumu ibikubiyemo ari 0.3%, igenamigambi ryambere ryigihe cya 28min, kandi igihe cyagenwe cyatangiye na 33min. Kurambura igihe cyo gushiraho birashobora guterwa nubuso bunini bwa Gypsusum ya Gypsum yateye imbere, bikagabanya igiciro cyimikino ngororamubiri kandi kikabuza gukabije kwa Gypsum cya Gypsum, bikabuza gukabije kwa Gypsum ya Gypsum, bikabuza igipimo cya Gypsum cya Gypsum cyo gukora sisitemu ihamye. Kuramba igihe cyo gushinga gypsum.
2.4 Ingaruka za Cellulose Ibikubiyemo Kumurongo wa Manicalicre Yubwinshi Byuzuye Gypsusum
Igipimo cyose cya Gypsum ifu, ifu ya hekede kandi yoroheje ni 100%, hamwe na dosage yifu ya gypsum, ifu ya hekes, ifu ya hekes, and regrdient idahinduka. Iyo Dosage ya HydroxyPropyl Methylcellse ni 0, 0.1%, 0.2% na 0.4%, imbaraga zoroheje kandi zikurura urumuri rwaciwe na gypsusu.
Ku myaka ya 1D, imbaraga zoroheje zoroheje zanditseho umunyamategeko gypsusud banje ko yiyongereye bwa mbere, hanyuma agabanuka kongera gukungeya hydroxyPro ibirimo Brethylcellse; Kumyaka 28d, imbaraga zoroheje zoroheje zanditseho gypsusud mortar parkor yiyongera muri hydroxyPropyl methylcellropyl methylcellpropyl methylcellrose, imbaraga zoroheje zoroheje zerekanaga igabanuka rya mbere, hanyuma ugabanuka. Iyo ibikubiye muri hydroxyproppopyl methylcellse ni 0.2%, imbaraga zoroheje zoroheje zinyuranye nimbaga ya hydroxypropyl. 28D. Ni ukubera ko ether ubupfura bufite ingaruka zo kugumana amazi no kubyimba, kandi amazi asaba ko hashobora kubaho ibipimo ngenderwaho byo kwiyongera, bityo bikaviramo kwiyongera kw'ibipimo by'ibice by'ibice byinshi, bigabanya imbaraga za Gypsin.
Umwanzuro
. Hamwe no kwiyongera kw'ifu ya Gypsusum yateye imbere, imbaraga zoroheje kandi zitera gypsing gypsing yoroshye zanduye muri rusange, ariko kwiyongera kwari nto.
