I-Gypsurury Gypsum yirhasi yeflegi eveliswe yi-sulsur-ene-fuels (amalahle, i-guctum), i-guctum yemveliso eveliswayo ngexesha le-furpum (kunye ne-guctum), ukusebenza kuthelekiswa naloo nto yezakhiwo zendalo. Ke ngoko, kukho iiphanda ezininzi kwaye zinokusetyenziswa kokusetyenziswa kwe-gypsurmer ebeziyo endaweni ye-gypsum yendalo ukuvelisa izixhobo zokuzibandakanya. Ukulungelelaniswa kwePolymer Polymer efana nearhente yokupheliswa kwamanzi, iarhente yokugcina amanzi kunye nombuso zizinto ezisebenzayo ezisebenzayo ekusebenzeni kwezinto ezinokwenzeka zokuziqokelela. Unxibelelwano kunye nendlela yezixhobo ezimbini ezinezinto ezinesamente yimicimbi efaneleyo. Ngenxa yeempawu zenkqubo yokwenziwa, ukulunga kwe-gypsum ye-gypsum incinci (ubungakanani be-suricle iphakathi, kwaye igrapho yomgubo ye-Gypsururd ihlwempu, kwaye udaka Ukulungiswa okulungiselelwe yiyo kulula ukwahlula-hlula, ukunyanzelwa kunye nokopha kwenzeka. I-Telupelose Ether yeyona nto isetyenziswayo esetyenziswayo kububele, kwaye ukusetyenziswa kwayo kusetyenziswa iarhente yokunciphisa amanzi sisiqinisekiso sokuziqhelanisa ne-Gypsim esekwe kwi-Gypsim esekwe kunye nokusebenza kwendlela yokwakhiwa kunye nokuziphatha okuhle.
Kweli phepha, ixabiso le-fluidity lisetyenziswa njengesalathiso solawulo (isidanga sokusasaza i-145 mm), ukugxila kwimpembelelo yomxholo we-selsulose ye-gelpurum-esekwe Izinto ezinokupheliswa, ukuphulukana nolwelo ngokuhamba kwexesha, kunye nokuhamba komthetho wefuthe lezinto ezisisiseko ezifana nexesha kunye neepropathi zoomatshini bokuqala; Kwangelo xesha, vavanya umthetho wempembelelo ye-ersulose ekukhutshweni kwe-Gydral Draft ye-Gydration yeGydral, kwaye ekuqaleni xoxa ngolu hlobo lwenkqubo yokugcwala kweGypsim Gypsurg .
I-1. Izinto ezingafunekiyo kunye neendlela zovavanyo
1.1 Izinto ezingafunekiyo
I-Gypsim Powder: I-Gypsurd Gypsim i-Gypsim eveliswa yinkampani eTangshan, eyona nto iphambili kwi-gemiral gypsum, ukwakhiwa kweefilimu kuboniswa kwiTheyibhile ye-1, kwaye iipropathi zayo zomzimba ziboniswa kwiTheyibhile 2.
umfanekiso
umfanekiso
Imixokelelwane ibandakanya: I-Selese Ether (i-Hydroxypropyl MethylcelcelceLcelose, i-HPMC yefutshane); I-Superplastizer WR; UDefoamer B-1; I-EVA iphinde yenzeka i-ElEx Powder S-05, zonke ezifumanekayo kwezorhwebo.
I-Aggreate: isanti yendalo yendalo, isanti elungileyo yenziwe nge-0.6 mm sieve.
1.2 Indlela yovavanyo
I-Gypsurling eqingqiweyo: Isanti: Amanzi = 1: 0.45, isixa esifanelekileyo sobunye besalathiso se-55 mm), ngokudityaniswa kwe-55 mm ye-55 mM ) 0, 0.5 ‰, 1.0 ‰, 2.0 ‰, 3.0 ‰ I-Ether Ithe Tete (HPMC-20,000); Qwalasela umthamo we-iluplose Ether ukuya kwi-1 ‰, khetha i-HPMC-20,000, i-HPMC-100,000 ye-HPMCYLCHLEL ), ukufundisisa idosi kunye nobunzima bemolekyuli (ixabiso le-viscosity) le-selsulose ifuthe lodaka olusekwe kwi-gyppum olwenziwe ngamafutha, kunye nexesha kunye neempawu zethutyana ze Umxube we-Gypsurful of Dypsur Indlela yovavanyo ethile yenziwa ngokungqinelana neemfuno ze-GB / T 1766.39.999
Ubushushu bovavanyo lwe-hydimer lwenziwa lusebenzisa isampulu ye-gypsurfurd ye-Gypsum kunye neesampulu ze-selsulose e-ITEROSE
2. Iziphumo kunye nohlalutyo
2.1 Isiphumo se-selsulose ether yomxholo kwipropathi esisiseko sodaka
Ngokwanda komxholo, ukusebenza kunye nokuntywila kodaka kuphuculwa kakhulu, ukuphulukana nolwelo ngokuhamba kwexesha kuncitshisiwe, kwaye umsebenzi olukhuni wonelisa, Ukugudisa kunye ne-aesthetics ziye zaphuculwa kakhulu. Kwangelo xesha, ukusetyenziswa kwamanzi kodaka ukuze kufezekiswe ulwelo olufanayo. Kwi-5 ‰, ukusetyenziswa kwamanzi kwandiswa nge-102%, kunye nexesha lokugqibela lokuseta kwalo lonke ixesha laliyi-100 imiz. Iipropathi zoomatshini bokuqala kodaka lwehle kakhulu ngokunyusa umxholo we-seluplose ether. Xa umxholo we-Teluplose Ether yayingu-5 ‰, amandla angama-24 h Amandla angama-24 H I-H RuGoxile kunye namandla ecinezelayo anciphile kwi-18.75% kunye ne-11.29% yesampulu engenanto. Amandla oxinzelelo yi-39.47% kunye ne-23,45% yesampulu engenanto ngokwahlukeneyo. Kufanelekile ukuba uqaphele ukuba ngokunyuka kwe-Arhente yokugcina amanzi, ukungcungcutheka kobuninzi bokuthoba nokuncitshiswa kwe-769 kg / m3 kwi-5 ‰, ukwehla kwe-15,56%. Ukuxinana kodaka kuncipha kwaye ukunyuka kwengozi, eso sesinye sezizathu zokuncipha okucacileyo kwiimpawu zodaka.
I-Teluplose Ether yi-polymer engeyiyo i-ionic polymer. Amaqela e-hydroxyl kwi-tensese etelsuse tiin kunye neeathom zeoksijini kwi-ethentreni ye-ether inokudibanisa iimolekyuli zamanzi ukwenza iimondi ze-hydrogen ukwenza amanzi, ngaloo ndlela idlala indima ekugcinweni kwamanzi. I-Macroscopilly ibonakaliswa njengenyukayo ekubalekeni kwesilayidi [5]. Ukunyuka kwe-varry viscofity ayiyi kunyusa ukusetyenziswa kwamanzi, kodwa ne-Ether inyibilikiswe i-Ether iya kuqinisekisa kumphezulu we-gypsim subles, ethintela ixesha lokuseta; Ngexesha lenkqubo eshukumisayo, inani elikhulu lamaxesha omoya liya kungeniswa. I-voids iya kwenza njengodaka, ekugqibeleni ukunciphisa amandla odaka. Ngokuqwalasela ngokuqonda ukusebenzisana kwamanzi okungcola kodaka, ukusebenza, ukubeka ixesha kunye neepropathi zoomatshini, kunye nokuqina koomatshini, njl njl.
2.2 Isiphumo sobunzima bemolekyuli ye-selsulose ether kwintsebenzo yodaka
Ngokwesiqhelo, ukuphakama okuphezulu kwaye kucocekile ukulunga kwe-Selese-Telupe, kungcono ukugcinwa kwamanzi kwaye kwandise amandla aphezulu. Intsebenzo iya kuchaphazeleka kakubi. Ke ngoko, impembelelo ye-selupolose yaza iimolekyuli ezahlukeneyo zemolekyuli kwipropathi esisiseko yezifo zeGypsim ezazichaphazeleka. Imfuno yamanzi yodaka inyuke ukuya kwinqanaba elithile, kodwa yayingenamagqabi kwixesha kunye nolwelo. Kwangelo xesha, amandla aguqukayo kunye nodaka lokulinganisa kumazwe ahlukeneyo abonisa indlela esezantsi, kodwa ukwehla kwakungaphantsi kakhulu kunefuthe lomxholo we-selsulose kwiipropathi zoomatshini. Isishwankathelo, ukunyuka kobunzima bemolekyuli ye-ether selethe ayinasiphumo esibonakalayo kwintsebenzo yomxube wodaka. Ukujonga lula ulwakhiwo, i-vis-viscofity ephantsi kunye ne-moleculase-moleculase-molese-molsulose i-ersulose kufuneka ikhethwe njengezixhobo zokuzimela zeGypsim ezisekwe kwiGypsim.
2.3 Isiphumo se-selsulose ether kubushushu be-hydration ye-gypsum eyenziweyo
Ngokwanda komxholo we-seluplose i-ether, i-exit Peak ye-hydration ye-gypsururd ngokuthe ngcembe inciphile, kwaye ixesha lendawo enobushushu linciphile, kodwa hayi ngokucacileyo. Oku kubonisa ukuba i-Elersese i-Ether ingalibazisa i-hydrationrey kunye nenqanaba le-hydration ye-gypsurfurd gypsum ukuya kwinqanaba elithile, ke umthamo akufuneki ube mkhulu kakhulu, kwaye kufuneka ulawulwe ngaphakathi kwe-1 ‰. Ingabonwa ukuba ifilimu yeColodal yasenziwa emva kokuba i-Ether Ether ihlangane namanzi i-goscum efakwe kwi-gypsurdssurd sublessuls efihlakeleyo, enciphisa imigangatho ye-gypsum ngaphambi kwe-2 h. Kwangelo xesha, ukugcinwa kwayo kwamanzi okwahlukileyo kunye nemiphumo yokuchithwa kwamanzi kunye nokuchithwa kwamanzi okutsala kunye nokubekwa yindlalifa kuyingenelo kwi-hydrasul ye-gypsurmer ebekwe kwinqanaba elizayo. Ukuzama ukuphakama, xa umthamo ofanelekileyo ulawulwa, i-ether sether ifuthe elinqamlezileyo kumgangatho we-hydration kunye nenqanaba le-hydration ye-gypsum. Kwangelo xesha, ukwanda kwesiqu somxholo we-selsulose kunye nobunzima bemolekyulu kuya kwandisa kakhulu uVeksi loLwanti kwaye ubonise ukusebenza kakuhle kwamanzi. Ukuze kuqinisekiswe ukuba ulwelo lwe-gypsurmer of gypsurd of Gypsim of Pared, ukusela kwamanzi kuya kunyuka kakhulu, nto leyo ebangelwa lixesha elide lodaka. Esona sizathu siphambili sokuhla kwiipropathi zoomatshini.
3. Ukuqukumbela
. Xa kuthelekiswa nomxholo, ubunzima bemolekyuli ye-selsulose i-ether unyuso alunampembelelo kangako kwezi ndawo zingasentla kodaka olungasentla kodaka. Ukuqwalaselwa kokuqonda, i-Sersese Ether kufuneka ikhethwe ngobunzima bemolekyuli (ixabiso le-viscofity lingaphantsi kwe-20 000 yeeparo), kwaye idosi kufuneka ilawulwe ngaphakathi kwe-1 ‰ yento enesimo sengqondo.
. Ukunyuka kokusetyenziswa kwamanzi kunye nokuncipha kwamanzi kwi-Bulk Derity zezona zizathu ziphambili zokuncipha kwendlela yohlobo lweGyppum.
