Uhlalutyo lwezizathu eziqhekezayo zokutyabeka i-gypsum layer
1. Uhlalutyo lwesizathu sokutyabeka i-gypsum imathiriyeli ekrwada
a) Udaka lwesakhiwo olungenaziqinisekiso
Ukwakha i-gypsum iqulethe umxholo ophezulu we-dihydrate gypsum, ekhokelela ekubopheni ngokukhawuleza kwe-gypsum yokutyabeka. Ukuze wenze i-gypsum yokutyabeka ibe nexesha elifanelekileyo lokuvula, i-retarder engaphezulu kufuneka yongezwe ukwenza imeko ibe yimbi; I-gypsum ene-soluble anhydrous ekwakheni i-gypsum AIII Umxholo ophezulu, ukwandiswa kwe-AIII kunamandla kune-β-hemihydrate gypsum kwinqanaba lamva, kwaye ukuguqulwa komthamo we-gypsum yokufaka i-gypsum ayilingani ngexesha lenkqubo yokunyanga, kubangela ukuqhekeka okukhulu; umxholo we-beta-hemihydrate gypsum enyangekayo ekwakheni i-gypsum iphantsi, kwaye kunye nenani elipheleleyo le-calcium sulfate liphantsi;I-gypsum yokwakha ivela kwi-chemical gypsum, i-fineness incinci, kwaye kukho iipowder ezininzi ezingaphezu kwe-400 mesh; ubungakanani besuntswana lokwakha igypsum ayiyodwa kwaye akukho gradation.
b) Izongezo ezikumgangatho ophantsi
Akukho phakathi koluhlu lwe-pH olusebenzayo kakhulu lwe-retarder; ukusebenza kwe-gel ye-retarder kuphantsi, inani lokusetyenziswa likhulu, amandla e-gypsum yokufaka i-gypsum ayancipha kakhulu, ikhefu phakathi kwexesha lokuqala lokumisela kunye nexesha lokugqibela lokumisela lide; izinga lokugcinwa kwamanzi kwi-cellulose ether liphantsi, ukulahleka kwamanzi kukhawuleza; i-cellulose ether inyibilika ngokucothayo, ayifanelekanga kulwakhiwo lokutshiza ngoomatshini.
Isisombululo:
a) Khetha i-gypsum yokwakha efanelekileyo kunye nezinzile, ixesha lokuqala lokumisela lingaphezulu kwe-3min, kwaye amandla e-flexural angaphezulu kwe-3MPa.
b) Khethai-cellulose etherkunye nobungakanani bamasuntswana amancinci kunye nomthamo obalaseleyo wokugcina amanzi.
c) Khetha iretarder enempembelelo encinci ekusekweni kwegypsum yokutyabeka.
2. Uhlalutyo lwesizathu sabasebenzi bokwakha
a) Umakhi weprojekthi uqesha abasebenzi abangenawo amava okwakha kwaye akaqhubeki noqeqesho olucwangcisiweyo. Abasebenzi bokwakha abazange baqonde iimpawu ezisisiseko kunye nezinto eziyimfuneko zokwakha i-gypsum yokufaka i-gypsum, kwaye abanako ukusebenza ngokwemigaqo yokwakha.
b) Ulawulo lobugcisa kunye nomgangatho wolawulo lweyunithi yobunjineli bekontraka lubuthathaka, akukho basebenzi bolawulo kwindawo yokwakha, kwaye imisebenzi engahambelaniyo yabasebenzi ayinakulungiswa ngexesha;
c) Uninzi lwemisebenzi ekhoyo yokutyabeka kunye negypsum ikwimo yokucoca, kugxilwe kubuninzi kunye nokungahoyi umgangatho.
Isisombululo:
a) Iikontraka zokutyabeka zeprojekthi zomeleza uqeqesho emsebenzini kwaye ziqhube ukubhengezwa kobugcisa phambi kokwakha.
b) Ukuqinisa ulawulo lwesiza sokwakha.
3. Uhlalutyo lwesizathu sokutyabeka
a) Amandla okugqibela e-gypsum yokutyabeka aphantsi kwaye akanako ukumelana noxinzelelo lokuncipha okubangelwa kukulahleka kwamanzi; amandla aphantsi okutyabeka i-gypsum ngenxa yezinto ezikrwada ezingafanelekanga okanye ifomula engafanelekanga.
b) Ukuxhatshazwa kwe-gypsum yokutyabeka akufanelekile, kwaye i-gypsum yokutyabeka iqokelela ezantsi, kwaye ubukhulu bukhulu, bubangela iintanda ezinqamlezileyo.
c) Ixesha lokuxutywa kodaka lwegypsum lifutshane, nto leyo ekhokelela kumxube ongalinganiyo wodaka, ukomelela okuphantsi, ukushwabana nokwandiswa okungalinganiyo komgangatho wokutyabeka.
d) Udaka olutyatyekwayo lwegypsum obelusetiwe ekuqaleni lungasetyenziswa kwakhona emva kokufakwa kwamanzi.
Isisombululo:
a) Sebenzisa i-gypsum yokutyabeka efanelekileyo, ehlangabezana neemfuno ze-GB/T28627-2012.
b) Sebenzisa izixhobo zokuxuba ezihambelanayo ukuqinisekisa ukuba igypsum yokutyabeka kunye namanzi zixutywe ngokulinganayo.
c) Akuvumelekanga ukongeza amanzi kwidaka esele ibekwe ekuqaleni, kwaye uyisebenzise kwakhona
4. Uhlalutyo lwembangela yezinto ezisisiseko
a) Okwangoku, izixhobo ezitsha zodonga zisetyenziswa kwi-masonry yezakhiwo ezenziwe ngaphambili, kwaye i-coefficient yabo yokunciphisa i-shrinkage inkulu. Xa ubudala beebhloko bunganelanga, okanye umgangatho womswakama weebhloko uphezulu kakhulu, njl., emva kwexesha lokumisa, ukuqhekeka kuya kubonakala eludongeni ngenxa yokulahlekelwa kwamanzi kunye nokunciphisa, kwaye i-plaster layer iya kuphazamiseka.
b) Ukudibanisa phakathi kwesakhiwo sesakhelo ilungu lekhonkrithi kunye nempahla yodonga apho izinto ezimbini ezahlukeneyo zidibana khona, kwaye i-coefficients yabo yokwandisa i-linear iyahluka. Xa iqondo lokushisa litshintsha, ukuguqulwa kwezinto ezimbini azihambelani, kwaye kuya kuvela ukuqhekeka okuhlukeneyo. Iikholamu zodonga eziqhelekileyo Ukuqhekeka okuthe nkqo phakathi kweepali kunye nokuqhekeka okuthe tye phantsi komqadi.
c) Sebenzisa i-aluminiyam formwork ukugalela ikhonkrithi kwisiza. Umphezulu wekhonkrithi ugudileyo kwaye ubopheleleke kakubi kumgca wokutyabeka. I-plastering plaster layer ikhutshwe ngokulula kwisiseko sesiseko, okubangela ukuqhekeka.
d) Izinto ezisisiseko kunye ne-gypsum yokufaka i-gypsum inomahluko omkhulu kwibakala lamandla, kwaye phantsi kwesenzo esidibeneyo sokumisa ukucutha kunye nokutshintsha kweqondo lokushisa, ukwandiswa kunye nokunciphisa akuhambelani, ngakumbi xa isiseko sodonga olukhanyayo lunobuninzi obuphantsi kunye namandla aphantsi, i-gypsum layering ivame ukuvelisa i-ice. Ukolula ukuqhekeka, kwanendawo enkulu yomngxuma. e) Umaleko wesiseko unomlinganiselo ophezulu wokufunxa amanzi kunye nesantya esikhawulezayo sokufunxa amanzi.
Isisombululo:
a) Isiseko esatyatyekwayo esandula ukutyatyekwa kufuneka some kangangeentsuku ezili-10 ehlotyeni kwaye ngaphezulu kweentsuku ezingama-20 ebusika phantsi kwemeko yokungena komoya kakuhle. Umphezulu ugudile kwaye isiseko sifunxa amanzi ngokukhawuleza. Kufuneka kusetyenziswe i-arhente yonxibelelwano;
b) Izixhobo zokuqinisa ezifana nelaphu legridi zisetyenziswa ekudibaneni kweendonga zezinto ezahlukeneyo
c) Izinto ezilula eludongeni kufuneka zigcinwe ngokupheleleyo.
5. Uhlalutyo lwesizathu senkqubo yokwakha
a) Uluhlu lwesiseko lome kakhulu ngaphandle kokumanzisa okufanelekileyo okanye ukusetyenziswa kwe-agent ye-interface. I-gypsum ye-plastering idibanisa nomgangatho wesiseko, umswakama kwi-gypsum yokufaka i-gypsum ixutywe ngokukhawuleza, amanzi alahlekile, kwaye umthamo we-plastering gypsum layer uyancipha, ubangele ukuqhekeka, okuchaphazela ukwanda kwamandla kunye nokunciphisa amandla okudibanisa.
b) Umgangatho wokwakhiwa kwesiseko umbi, kwaye umaleko wegypsum wasekhaya utyebile kakhulu. Ukuba i-plastering plaster ifakwe ngexesha elinye, i-mortar iya kuwa kwaye yenze iintanda ezithe tye.
c) Indawo yokubeka umbane wamanzi ayiphathwanga kakuhle. Iindawo zokubeka i-Hydropower azigcwaliswa nge-caulking gypsum okanye ikhonkrithi yelitye elicikizekileyo kunye ne-ejenti yokwandisa, okukhokelela ekuqhekekeni kwe-shrinkage, okukhokelela ekuqhekekeni kwe-gypsum layering.
d) Akukho nyango lukhethekileyo kwiimbambo zokubhoboza, kunye ne-gypsum layering eyakhiwe kwindawo enkulu iyaqhekeka kwiimbambo zokubetha.
Isisombululo:
a) Sebenzisa iarhente yojongano olukumgangatho ophezulu ukunyanga umaleko wesiseko ngamandla aphantsi kunye nokufunxwa kwamanzi okukhawulezayo.
b) Ubungqingqwa bomaleko wegypsum wokutyatyekwa bukhulu kakhulu, bungaphezulu kwe-50mm, kwaye kufuneka icholwe ngokwamanqanaba.
c) Ukuqhuba inkqubo yokwakha nokomeleza ulawulo lomgangatho wesiza sokwakha.
6. Uhlalutyo lwesizathu sommandla wokwakha
a) Imozulu yomile kwaye ishushu.
b) Isantya esiphezulu somoya
c) Ekuqaleni kwentlakohlaza nehlobo, iqondo lobushushu liphezulu kwaye nokufuma kuphantsi.
Isisombululo:
a) Ulwakhiwo aluvumelekanga xa kukho umoya onamandla wenqanaba lesihlanu okanye ngaphezulu, kwaye ulwakhiwo aluvumelekanga xa ubushushu be-ambient bungaphezulu kwama-40 ℃.
b) Ekuqaleni kwentlakohlaza nehlobo, hlengahlengisa indlela yokuvelisa yokutyabeka igypsum.
