Kuyini izinto zokwandisa ezingashi umlilo？

Izinto zokwandisa ezingashiuhlobo lwezinto zokwakha ezenzelwe ukwanda lapho zichayeka emazingeni okushisa aphezulu, zakha ungqimba lwe-char oluvikelayo olusiza ukuvala izikhala nokuvimbela ukusabalala komlilo, intuthu, kanye namagesi anobuthi. Lezi zinto zivame ukusetshenziswa ezinhlelweni zokuvimbela umlilo ukuze kuthuthukiswe ukumelana nomlilo kwezakhiwo, izinhlelo zikagesi, kanye nezakhiwo zezimboni.

Izinhlobo Zezinto Zokwandisa Ezingashi:

1. Amagwebu Anwebekayo Angashisi Nokutywina
   • Isetshenziswa eduze kwamapayipi, izintambo, kanye namajoyinti ukwandisa nokuvala izikhala ngesikhathi somlilo.
   • Isibonelo: Igwebu le-Intumescent firestop.
2. Izembozo Nopende Ezingaphakathi Kwe-Intumescent
   • Vuvukala uma kushiswa, kwakha ungqimba oluvikelayo phezu kwensimbi, ukhuni, noma ezinye izakhi zesakhiwo.
   • Isibonelo: Upende ongashisi wezinsimbi zensimbi.
3. Ama-Joint Fillers Okukhulisa Angashi
   • Isetshenziswa ekwakheni amalunga ukuvumela ukunyakaza ngenkathi igcina ukumelana nomlilo.
   • Isibonelo: Uboya obunezicucu ezingaphakathi kwesisu.
4. I-mortar ne-putty engashi
   • Iyanwebeka ukuze igcwalise imifantu nezimbobo ezindongeni, phansi, kanye nezimpawu zokungena.
   • Isibonelo: I-silicone sealant engashi.
5. Imichilo Ye-Intumescent Esekelwe Ku-Graphite
   • Isetshenziswa eminyango nasemafasiteleni ukwandisa nokuvimba ukusabalala komlilo.

Izakhiwo Eziyinhloko:

• Isilinganiso Sokwanda:Ingakhula ngokuphindwe ka-5–50 ngobukhulu bayo bokuqala uma ishiswa.
• Ukumelana Nomlilo:Imelana namazinga okushisa kusukela ku-500°C kuya ngaphezu kuka-1000°C.
• Ukuvikela:Yakha ungqimba olushile olunciphisa ukudluliselwa kokushisa.
• Ukuvimba Intuthu Nobuthi:Kuvimbela ukuvuza kwegesi okuyingozi.

Izicelo:

• Ukungena kwekhebula likagesi elingangenisi umlilo.
• Ukuvala izikhala ezindongeni nasezindlini ezilinganiselwe umlilo.
• Ukuvikela insimbi yesakhiwo ekuweni okubangelwa ukushisa.
• Iminyango yomlilo, imibhobho ye-HVAC, kanye nokungena kwamapayipi.

Lezi zinto zibalulekile ezinhlelweni zokuvikela umlilo ezingasebenzi, ziqinisekisa ukuhambisana nemithetho yokuphepha kwesakhiwo (isb., ASTM E814, UL 1479). Ungathanda yini izincomo zesicelo esithile?
