Ulusi wagalasi uli ndi zabwino zambiri monga mphamvu yayikulu komanso kulemera kopepuka, kukana dzimbiri, kukana kutentha kwambiri, kukana kutenthetsa bwino magetsi, ndi zina zotero. Ndi chimodzi mwa zinthu zopangira zomwe zimagwiritsidwa ntchito kwambiri popanga zinthu zophatikizika. Nthawi yomweyo, China ndiyenso wopanga ulusi wagalasi waukulu kwambiri padziko lonse lapansi.
1. Kodi ulusi ndi chiyanigalasi?
Ulusi wagalasi ndi chinthu chosapangidwa ndi chitsulo chomwe chimagwira ntchito bwino kwambiri, ndi mchere wachilengedwe wokhala ndi silika ngati chinthu chachikulu chopangira, umawonjezera zinthu zinazake zachitsulo chosapangidwa ndi oxide, zosakanikirana mofanana, zosungunuka kutentha kwambiri, madzi osungunuka agalasi kudzera mu funnel outflow, ntchito ya mphamvu yokoka yokoka mwachangu imakokedwa ndikuziziritsidwa mwachangu ndikusinthidwa kukhala ulusi wabwino kwambiri wopitilira.
Ulusi wagalasi monofilament m'mimba mwake kuyambira ma microns angapo mpaka ma microns opitilira makumi awiri, ofanana ndi tsitsi la 1/20-1/5, mtolo uliwonse wa ulusi umapangidwa ndi mazana kapena zikwi za monofilaments.
Kapangidwe kake ka ulusi wagalasi: Mawonekedwe a pamwamba pake ndi osalala, gawo lake ndi lozungulira, lozungulira kuti lipirire mphamvu yonyamula; mpweya ndi madzi kudzera mu kukana kwake ndi zazing'ono, koma pamwamba pake ndi posalala kotero kuti mphamvu yogwirira ulusiyo ndi yaying'ono, yosagwirizana ndi utomoni; kachulukidwe kake nthawi zambiri kamakhala 2.50-2.70 g/cm3, kutengera makamaka kapangidwe ka galasi; mphamvu yokoka kuposa ulusi wina wachilengedwe, ulusi wopangidwa umakhala wokwera; zipangizo zosweka, kutalika kwake pakagwa ndi kochepa kwambiri. Kukana kwa madzi ndi asidi ndikwabwino, pomwe kukana kwa alkali ndi kofooka.
2.Gulu la ulusi wagalasi
Ikhoza kugawidwa m'magulu a ulusi wagalasi wopitilira, ulusi wagalasi waufupi (ulusi wagalasi wokhazikika) ndi ulusi wagalasi wautali (LFT) kuchokera ku gulu lautali.
Kuchokera ku zitsulo za alkali, zitsulozi zingagawidwe m'magulu awiri: otsika, apakati ndi apamwamba, nthawi zambiri amasinthidwa ndi zitsulo zopanda alkali, ndiko kuti, ulusi wa galasi wa E, ulusi wa galasi wa E womwe umagwiritsidwa ntchito m'nyumba nthawi zambiri umagwiritsidwa ntchito.
3.Kodi ulusi wagalasi ungagwiritsidwe ntchito chiyani
Ulusi wagalasi uli ndi mphamvu yokoka kwambiri, kusinthasintha kwakukulu, kusayaka, kukana mankhwala, kuyamwa madzi pang'ono, magwiridwe antchito abwino komanso makhalidwe ena abwino, nthawi zambiri umagwiritsidwa ntchito ngati zinthu zophatikizika muzinthu zolimbitsa, zida zamagetsi zotetezera kutentha ndi zida zotetezera kutentha, gawo lapansi la dera, ndi zina zotero, zomwe zimagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana.
Ulusi wagalasi wakunja umagawidwa m'magulu anayi malinga ndi momwe zinthu zimagwiritsidwira ntchito: zipangizo zolimbikitsira mapulasitiki otenthetsera kutentha, zipangizo zolimbikitsira ulusi wagalasi za thermoplastics, zipangizo zolimbikitsira simenti za gypsum, ndi nsalu za ulusi wagalasi, zomwe zipangizo zolimbikitsira zimakhala 70-75% ndipo zipangizo za ulusi wagalasi zimakhala 25-30%. Kuchokera ku kufunikira kwapansi, zomangamanga zimakhala pafupifupi 38% (kuphatikiza mapaipi, kuchotsa mchere m'madzi, kutentha kwa nyumba ndi kutsekereza madzi, kusunga madzi, ndi zina zotero), zoyendera zimakhala pafupifupi 27-28% (bwato, magalimoto, njanji yothamanga kwambiri, ndi zina zotero) ndipo zamagetsi zimakhala pafupifupi 17%.
Powombetsa mkota, madera ogwiritsira ntchito ulusi wagalasi ndi monga mayendedwe, zipangizo zomangira, mafakitale amagetsi, mafakitale amakina, mafakitale a petrochemical, zosangalatsa ndi chikhalidwe, ndi ukadaulo wachitetezo cha dziko.
