Blocks igesi silicate: Ukucaciswa. Ubukhulu, ukubuyekezwa kanye namanani

Negesi silicate amabhlogo, izici lobuchwepheshe zazo okusesihlokweni esithi, namuhla basakaza angabacwasi. Lokhu kungenxa yokuthi i- ukhonkolo evundile has a isisindo ongaphakeme eliphezulu.

Ukwakheka gazosilikata

Esikhathini ukukhiqizwa wathi imikhiqizo high isetshenziswa Portland usimende, phakathi izithako okumele liqukathe silicate calcium inani elilingana ½ isisindo ingqikithi. Phakathi kwezinye izinto, le mithi yengezwe isihlabathi, okuyinto has a asebenza ngebhethri (85% noma ngaphezulu). Nakuba daka nobumba kule ingxenye akufanele futhi iyophakama kuno-2%. Yengezwe ngo inqubo zokukhiqiza, kanye lime, quicklime, lapho eqeda izinga imayelana 5-15 imizuzu, kodwa i-nitrous calcium ne-magnesium therein kufanele kube cishe 70% noma ngaphezulu. Imikhiqizo kufanele lichaza ekwakheni kanye ejenti ukushaywa, okuyinto eyenziwe aluminium powder. Kukhona izikhubekiso, futhi uketshezi futhi sulfanol S.

Blocks igesi silicate, intengo ozokwethulwa ngezansi kungenzeka ekhiqizwa usebenzisa i autoclave noma ngaphandle kwalo. Eyokuqala indlela zokukhiqiza ivumela ukwakha amabhlogo, ngamandla okuyinto ukuncipha kakhulu kunalokhu etholwe nayo ngakho umxhwele, ukuthi baziswa abathengi.

Imikhiqizo ekhiqizwa usebenzisa i autoclave, kodwa ungedluli esigabeni omiswe, babe izikhathi 5 ukuncipha kuzenze zibathinte nakakhulu uma kuqhathaniswa amabhlogo ukuthi ishile i autoclave, ngaphezu, bona Nokho, sibe namandla hhayi njengoba umxhwele, futhi zibiza kancane.

Autoclave yokukhiqiza indlela isetshenziswa, ngokuvamile amabhizinisi ezinkulu, kungenxa yokuthi inqubo enobuchwepheshe futhi kudinga kokuchitha amandla amaningi. Emabhuloki e inqubo production kushunqe isinyathelo ngaso 200 ⁰ C, kuyilapho inkomba ingcindezi ifinyelela 1.2 MPA. Abakhiqizi ukushintsha isilinganiso izithako zifakwe Ukwakheka ingxube, okuyinto ivumela ukushintsha izici ezibonakalayo. Ngokwesibonelo, nekwandzisa umtsamo usimende buyothuthuka block ukumelana Nokho, porosity kuzoncishiswa, ngenxa umthelela izinga ukushisa ubunjiniyela kanye conductivity ezishisayo uzobe kakhulu lenyuka.

izici lobuchwepheshe

Blocks igesi silicate, Ukucaciswa kuthiwa mhlawumbe kubhekwe ngaphambi yokufuna, zihlukaniswe izinhlobo ngu kwabantu. Kuye lokhu sibalo, emabhuloki kungenzeka kwesakhiwo, constructional nokushisa ekuvikeleni nokushisa olubamba ukushisa. imikhiqizo wezakhiwo - ukubala nalawo aba kwabantu, okhethwe maka D700, kodwa hhayi ngaphansi. Le mikhiqizo asetshenziswa ekwakhiweni umthwalo esindayo izindonga ezakhiweni, okuphakama kwawo akuyona ezingaphezu kwezingu-3 izibuya. imikhiqizo Constructional ukushisa-nangokuvikela futhi ube ukuminyana kuleli uhla D500-D700. Lokhu kwaziswa kahle ukwakhiwa ngodonga ingaphakathi kanye ezindongeni zezakhiwo, okuyinto musa idlule ukuphakama 2 izibuya.

Nangokuvikela amabhlogo igesi silicate, izici lobuchwepheshe ibalulekile ukwazi, ngaphambi kokusebenzisa yabo ekwakhiweni izindonga babe porosity ngokwanele umxhwele, okukhombisa ukuthi namandla abo ephansi. inhlanganiso yabo uyalingana umkhawulo we D400, bajwayele njengendlela material ukuthi uyakwazi ukwandisa izimfanelo ezishisayo kanye lobuchwepheshe izindonga, eyakhelwe engaphansi izinto eyonga amandla.

ezishisayo izimfanelo conductivity

Ngokuya conductivity ezishisayo igesi silicate it has a ukusebenza pretty umxhwele. I conductivity ezishisayo kuyinto ngokulingana ngqo kwabantu. Ngakho, gazolikat brand D400 has a conductivity ezishisayo esingaphansi noma ilingane 0.08-0.10 W / m ° C. Ngokuphathelene sha amabhlogo D500-D700, wathi ukubonise zokhahlamba kusuka 0.12 kuya 0.18 W / m ° C. D700 isitembu amabhlogo babe conductivity ephakeme ezishisayo ku uhla 0.18-0.20 W / m ° C.

frost ukumelana

Negesi silicate amabhlogo, okuyinto Ukucaciswa kufanele nakanjani nazi ngaphambi kokuthenga, futhi ifa izimfanelo ezithile hardiness, okuyinto incike isibalo ikhule ezimbotsheni. Ngakho, amayunithi ahlukahlukene ngesisekelo igesi silicate uyakwazi withstanding mayelana 15-35 ngemijikelezo ukuqanda incibilikiswa. Nokho, ukuthuthukiswa kwezobuchwepheshe akuyona esikhundleni, kanti ezinye izinkampani baye bafunda ukukhiqiza amayunithi ukuthi bayakwazi ukuba ibhekane umjikelezo efana 50, 75 noma ngisho 100 izikhathi, okuyinto ekhangayo, kanye isisindo amabhlogo silicate. Kodwa uma ukuthenga imikhiqizo ukuba yakhiqizwa ngokuhambisana GOST 25485-89, lapho indlu udinga ukugxila inkomba frost brand D500, ka imijikelezo 35.

Ubukhulu nesisindo amabhlogo

Ngaphambi kokuba uqale ukwakha izindonga amabhlogo silicate, udinga ukwazi ukuthi ubukhulu angaba umkhiqizo. Njengomthetho, ukudayiswa kuyinto block, izinhlangothi zazo yilezi: 600h200h300, 600h100h300, 500h200h300, 250h400h600 futhi 250h250h600 mm, kodwa lokhu akulona uhlu oluphelele.

block incike kwabantu uyaca. Ngakho, uma block has D700 uphawu futhi Ubukhulu bayo uhla 600x200x300 mm, isisindo unit kuzohluka kusuka 20 kuya 40 kg. Kodwa D700 isitembu block nge Ubukhulu ngaphakathi 600x100x300 mm has a okulingana nesisindo 10-16 kg. Blocks nge kwabantu kusukela D500 ukuba D600 futhi ubukhulu 600x200x300 mm abe isisindo 17 kuya ku-30 kg. Ukuze gazosilikata ukuminyana D500-D600 futhi yayo usayizi 600x100x300 mm iyunithi isisindo ilingana 9-13 kg. Lapho ukuminyana D400 nobungako zilingane 600x200x300 mm, isisindo kuyoba ulingana 14-21 kg. Mark gazosilikata le D400, limbozwe ubukhulu 600x100x300 mm nesisindo cishe 5.10 kg.

ezicini ezinhle amabhlogo silicate

Uma wazi ukuthi ukushuba we amabhlogo igesi-silicate, ungafunda mayelana nezinye izici zayo, kuhlanganise izinhlangothi emihle nemibi. Ohlangothini plus, ungakhetha isisindo ongaphakeme namandla, okuyinto kwanele ukwakhiwa ongaphakeme liphumele. Ngaphezu kwalokho, le mikhiqizo babe nezimfanelo ezinhle kakhulu ukushisa ukonga. Ngalezi izindonga uya umsindo kubi, futhi izindleko umkhiqizo konke iyatholakala. Amabhulokhi ungayishisi. Ukukhiqiza ukwakhiwa usebenzisa amabhlogo silicate kungenziwa okusekelwe anamathelayo ekhethekile evumela ukuthola ukushuba okungenani umphetho.

izimfanelo ezimbi

Uma ucabangela nemibi amabhlogo silicate, singakwazi ukuhlukanisa isidingo ngombala Ingaphandle, ethuthukisa sobuhle bayo izindonga. Amabhulokhi akuzona njengoba ezikhangayo lapho umthengi uthola ngezimfanelo zabo hygroscopic. Futhi ngaphambi kokuqala okwakha ayedingeka ukuze ukwakha isisekelo esiqinile.

Inani amayunithi

Negesi silicate amabhlogo, okuyinto intengo ingase yehluke kuye ngesistimu ubukhulu, kuvunyelwe beka ngokwakho. Isisindo sawo aluhileli ukusetshenziswa imishini ekhethekile. Ngakho, uma block has a usayizi ngaphakathi 600h100h300 mm, izindleko zayo per unit kuyoba ulingana $ 1.8-1.9.
