Nsalu Yopanda Ulusi wa Basalt: "Chotchinga Chogwira Ntchito" ndi "Yankho Lothandiza Kuteteza Chilengedwe" la Zinthu Zambiri

Nsalu yopanda ulusi wa basaltndi nsalu yopangidwa mwa kuyika ulusi wodulidwa wa basalt kapena ulusi wopitilira mu ukonde mwachisawawa kapena molunjika kenako nkuulimbitsa kudzera mu njira zosalukidwa monga kuboola singano, kulowetsa madzi m'madzi, ndi kusungunula (zomwe zimafuna kuwonjezera ulusi wochepa wosungunuka). Phindu lake lalikulu lili mu "kulamulira kapangidwe kake" ndi "kusinthasintha kwa magwiridwe antchito." Mwa kusintha kutalika kwa ulusi, njira yoyika ukonde, ndi njira yolimbikitsira, thupi lake ndi Mankhwala Makhalidwe ake akhoza kusinthidwa kuti agwirizane ndi zochitika zosiyanasiyana. Nsalu yopanda ulusi wa basalt ndi mawu wamba. Mwachitsanzo, kampani yathuMat ya Tishu ya Basalt Fiber Surfacing ndi Chigoba Chopanda Nsalu cha Basalt onse awiri ali m'gulu ili.

1. Makhalidwe Abwino Kwambiri: Ubwino Wofunika wa Kapangidwe Kosinthasintha ndi Ntchito Zosiyanasiyana

Kapangidwe ndi Kukhuthala Kosinthika: Kuyambira nsalu yopyapyala yosefera (0.1mm) mpaka thonje lokhuthala lonyamula mawu (50mm), kuchuluka ndi kuchuluka kwa zigawo za ukonde kumatha kulamulidwa bwino; kufalikira kwa ulusi mwachisawawa kumapangitsa kuti zinthuzo zikhale "isotropic," pomwe kuyika ukonde molunjika kumatha kuwonjezera mphamvu zamakina m'njira zinazake. Kuchita bwino kwambiri kosefera: M'mimba mwake wa ulusi ndi wabwino (mpaka 5~10μm) ndipo porosity ndi yayikulu (mpaka 70%~90%), yokhala ndi mphamvu yosunga fumbi ndi tinthu tating'onoting'ono toposa 99% (mphamvu yosefera ya PM2.5 ≥95%), komanso kukana mpweya pang'ono.

Chitetezo ndi chitetezo cha chilengedwe: Zinthu zopangirazi ndi basalt yachilengedwe, yopanda kutulutsidwa kwa zinthu zoopsa monga formaldehyde ndi benzene; zimatha kuwonongeka mwachilengedwe kapena kutenthedwa zitatayidwa (kutentha sikutulutsa mpweya wapoizoni, ndipo zotsalirazo ndi ma oxide osapangidwa), zomwe zimakwaniritsa zofunikira za "kupanga kobiriwira".

Kuphatikiza ntchito zambiri: Kudzera mu njira zophatikizana (monga zophatikizana ndi ulusi wa kaboni ndi Ulusi wa Galasi) kapena mankhwala opaka utoto (monga zopaka utoto zosalowa madzi ndi zopaka utoto zoletsa mabakiteriya), zimatha kuphatikiza zinthu zambiri monga "kusefa + kutchinjiriza kutentha" ndi "kuteteza + kupuma bwino".

2. Mtengo wofunikira kwambiri: Kuyambira kusefa mafakitale mpaka chitetezo cha anthu

(1) Malo osefera mafakitale: "Njira yoyambira" yoyeretsera bwino kwambiri

Nsalu yopanda ulusi wa basalt yakhala chinthu chomwe chimakonda kusefedwa pansi pa mikhalidwe yovuta kwambiri yogwirira ntchito chifukwa cha kukana kutentha kwambiri komanso dzimbiri la mankhwala. Mu kusefedwa kwa mpweya wa flue wotentha kwambiri, zida zosefera za m'nyumba zomwe zimagwiritsidwa ntchito m'mafakitale monga chitsulo, simenti, ndi zinyalala zimatha kusefa fumbi ndi tinthu tating'onoting'ono toopsa (monga zonyamula dioxin) mu mpweya wa flue kwa nthawi yayitali kutentha kwa 200-400℃, ndi moyo wautali nthawi 3-5 kuposa zida zosefera za polyester zachikhalidwe. Mu kusefedwa kwamadzimadzi, ngati nsalu yolondola yosefera m'mafakitale a mankhwala ndi electroplating, imatha kusefa zonyansa zomwe zimapachikidwa mu njira za acidic ndi alkaline popanda kuchitapo kanthu ndi mankhwala, ndikukwaniritsa kulondola kwa kusefedwa kwa 1-5μm.

(2) Chitetezo ndi Kuteteza Chilengedwe: "Chitsimikizo Chachiwiri" cha Chitetezo ndi Kubiriwira

Pankhani ya zida zodzitetezera, imagwiritsidwa ntchito popanga zophimba fumbi, zophimba zophimba nkhope, ndi zotchingira kutentha kwa zovala zozimitsira moto, kuphatikiza mpweya wabwino komanso chitetezo—poyerekeza ndi nsalu yopanda ulusi yosungunuka, imakhala ndi mphamvu yolimba kutentha, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito kutentha kwambiri monga kuwotcherera ndi kuzimitsa moto, ndipo ilibe chiopsezo cha kusonkhanitsa magetsi osasinthasintha, zomwe zimapangitsa kuti ikhale yoyenera malo oyaka moto komanso ophulika. Pankhani yoteteza chilengedwe ndi kubwezeretsa chilengedwe, monga chotchingira cha geomembrane chokonzera nthaka komanso choteteza zomera m'mphepete mwa mtsinje, kukana kwake kwa asidi ndi alkali komanso mphamvu zake zoletsa kuwonongeka kwa chilengedwe zimatsimikizira kukhazikika kwa kapangidwe kake kwa nthawi yayitali pomwe kumalola madzi ndi michere kulowa, motero zimathandiza kubwezeretsa chilengedwe.

(3) Zipangizo zomangira zogwira ntchito: "Kukonza zochitika" kuti zikhale zotonthoza komanso zopulumutsa mphamvu

Ponena za zinthu zomwe zimayamwa mawu komanso zochepetsa phokoso, nsalu yolimba yosaluka yobowoledwa ndi singano imagwiritsidwa ntchito ngati gawo loyamwa mawu pomanga makoma amkati, ma elevator shaft, ndi ma tunnel a sitima. Kudzera mu mphamvu yowunikira ndi kunyowetsa mafunde a mawu ndi ma pores a ulusi, imatha kuchepetsa phokoso ndi 15 ~ 25dB. Imalimbananso ndi kutentha kwambiri komanso yosayaka (oxygen index ≥40%, yomwe ndi chinthu chosayaka). Ponena za zinthu zoyamwa kutentha, imagwiritsidwa ntchito pomanga zigawo zoyamwa makoma akunja ndi manja oyamwa zida zamafakitale. Ili ndi mphamvu yotsika ya kutentha (≤0.038W/(m·K)) ndipo simatenga chinyezi kapena kukhala ndi chiopsezo cha kukula kwa nkhungu, zomwe zili bwino kuposa zipangizo zoyamwa ubweya wa miyala.
