Ukufakwa kwepayipi kwe-calcium busicationIngabe impahla eqinile, engamelana nomlilo eyenzelwe ngokukhethekile ukusonga amapayipi, ama-ducts, nezinye izikhala ze-cylindrical. Kunziwe enjiniyela kusuka kunhlanganisela yeI-calcium milicate. Le nhlanganisela idala izinto eziminyene, eziqinile ezidlula ezindaweni ezishisa kakhulu ngenkathi zigcina ubuqotho bezinhlekelele.
Ngokungafani nokufakwa kwe-foam-based noma i-fibrous (e.g., i-fiberglass noma i-polystyrene), i-calcium milstyrene), i-calcium silication ayinakuphikwa futhi inikezela ukumelana okuphezulu komswakama, amakhemikhali, kanye nokushisa kokusebenza ngokuhamba kwesikhathi). Ngokuvamile kufakwa ezingxenyeni ze-cylindrical, imikhono, noma amabhodi, okwenza kube lula ukufaka amapayipi ama-dipe ahlukahlukene.
Ukuqonda ukusebenza kwayo, ake sihlole izingxenye zalo eziyinhloko:
Yini ebeka i-calcium lithulisa ngaphandle kwezinye izinto zokufaka? Nazi izici zayo ezichazayo:
I-calcium silicate ingakwazi ukumelana namazinga okushisa aqhubekayo okusebenza kuze kubeI-650 ° C (1,200 ° F)Nokuvezwa kwesikhashana esifushane kuze kube yi-1 ° C (1,832 ° F). Lokhu kwenza kube kuhle ngezinhlelo zokusebenza eziphakeme eziphakeme njengamapayipi e-Steam, imigqa ye-boiler, kanye nezinhlelo zokufudumala kwezimboni.
Ngokuvuselelwa okushisayo (i-K-value) ephansi njengoba0.045-0.065 W (m · k)Ku-100 ° C, kunciphisa ukulahleka kokushisa noma inzuzo. Isibonelo, ukufaka ipayipi le-steam-yobubanzi engama-50mm nge-calcium busication kunganciphisa ukulahleka kokushisa ngo-70-80% uma kuqhathaniswa namapayipi angenakuqhathaniswa, ukwehlisa izindleko zamandla kakhulu.
Ihlukaniswe ngokuthiI-A1 ayinayoNgaphansi kwe-EN 13501-1 Lokhu kubucayi ezindaweni ezithambekele emlilweni njengezitshalo zamandla, ukufucuza amakhemikhali, nezinhlelo ze-HVAC.
Ngokungafani ne-Foam noma i-cellulose ukufakwa, i-calcium milicate ichithekile yamanzi engokwemvelo (ikakhulukazi uma iphathwa ngezithasiselo ze-hydrophobic). Iphikisa ukumunwa komswakama, ukuvimbela ukukhula kokukhulisa, ukugqwala kwamapayipi, nezinkinga ezibalulekile ezingonakaliso ezindaweni ezinomswakama noma ezimanzi (e.g. izikhungo zasogwini, amapayipi angaphansi komhlaba).
Ngokufakwa okufanele, ukufakwa kwe-calcium silicate kugcinaIminyaka engama-20-30(Noma ngaphezulu), izinto eziphuma emfushane ezifuywayo ezifana ne-foam (iminyaka eyi-10-15) noma i-fiberglass (iminyaka engu-15- 20). Ukuqina kwawo kunciphisa ukulungiswa kanye nezindleko zokubuyiselwa isikhathi ngokuhamba kwesikhathi.
Ukunquma ukuthi ngabe i-calcium milium iyisinqumo esifanele, kuyasiza ukuyiqhathanisa ngezindlela ezivamile:
| Into uqobo lwayo | I-MAX TEMP | Isilinganiso somlilo | Ukumelana nomswakama | Ukuphila isikhathi eside |
|---|---|---|---|---|
| I-calcium milicate | Kufika ku-650 ° C | I-A1 ayinayo | -Hle kakhulu | Iminyaka engama-20- 30 + |
| Ijibha | Kufika ku-400 ° C | I-Class B (okuhlangene) | Abampofu (abamunca umswakama) | Iminyaka eyi-10-15 |
| Foam (e.g., xps eps) | Kufika ku-75 ° C | I-Class B-C | Okulinganiselayo (ukudicilela phansi ngomswakama) | Iminyaka engu-5-10 |
| Uboya bezimbiwa | Kufika ku-700 ° C | Class A1-A2 | Kuhle (kepha kuqinile) | Iminyaka eyi-15-25 |
Njengoba itafula libonisa, amabhalansi asilisa e-calcium alithuli aphezulu wokushisa okushisa, ukuphepha komlilo kanye nokumelana nomswakama okungcono kunezindlela eziningi.
Njengoba kunikezwe izakhiwo zalo eziqinile, ukufakwa kwe-calcium silticate kusetshenziswa kuyo yonke imboni ehlukahlukene:
Izitshalo zamandla, ukufucuza amakhemikhali, kanye nezindawo zokusebenza zokudla zincike emapayiphu okushisa aphezulu ukuhambisa umusi, uketshezi olufudumele, noma izinto zokusetshenziswa. Amandla we-calcium silication okuphatha ukushisa okwedlulele kanye nokumelana nokugqwala kwenza kube fanele ilungele imigqa ye-boile feedwater, i-steam mains, futhi icubungule amapayipi.
Ukushisa, umoya omncane, nezinhlelo zokufaka umoya zisebenzisa amapayipi ukusabalalisa amanzi ashisayo noma esiqandisini. I-calcium silalise i-insulates imigqa yamanzi ebiyelwe (ukuvimbela ukubumba kanye nokubumba) kanye namapayipi okushisa amanzi ashisayo (ukunciphisa imfucumfucu yamandla ezindaweni zokuhlala, ezentengiso, noma zezakhiwo zezikhungo).
Amanethiwekhi okushisa angaphansi komhlaba ezimotweni ezibandayo (e.g., Scandinavia, Canada) adinga ukufakwa okumelana nokuvezwa kwamanzi asemhlabeni. Ukumelana nomswakama ka-calcium bulianies kanye nefomu eliqinile lesikhala senza liphelele kumapayipi afaka amapayipi emadolobheni aminyene.
Ama-sprinklers omlilo, ama-steppipes, kanye nama-ducts okuqothuka kwentuthu kudinga ukufakwa okungapheli kokushisa ngokweqile. Isimo se-calcium milialible esingavuselelwanga siqinisekisa lezi zinhlelo zihlala zisebenza ngesikhathi sezimo eziphuthumayo, zihambisana namakhodi omlilo afana ne-NFPA 25.
Ngenkathi kunconywa ukufakwa kochwepheshe, nansi umbono osheshayo wenqubo:
Ukufakwa kwepayipi kwe-calcium busicationKungaphezu nje kokuthi "blocker yokushisa" -Ingxenye ebalulekile ezintweni ezisebenza kahle, eziphephile, ezihlala ezimbonini nasezentengiso nezimboni. Ngokuhlanganisa ukuqina kokushisa okuphezulu, ukuphepha ngomlilo, kanye nokumelana nomswakama, kuvela izinto zokufakwa kwendabuko zokufakwa kwezicelo ezifunwayo.
