Pepala la mphirandi zinthu zapadera kwambiri, zomwe zimagwiritsidwa ntchito kwambiri, kuphatikizapo makampani omanga. Chifukwa chake, imagwiritsidwa ntchito pomanga ndi kukonza nyumba.
Ndi mbiri yanjipepala la mphira?
Pepala la mphiraamapangidwa ndi mphira wa silicane, ndiposilika rabarItha kugawidwa m'mitundu iwiri: Silica sica gel ndi itorganic silika gel. Itorganic sica gels ndi zinthu zodziwika bwino kwambiri. Pamapeto pake zimapangidwa ndi sumu ya sodium ndi sulfuric acid, ndipo pambuyo pa mankhwala angapo monga ukalamba ndi thovu la acid.
Silika gel ndiwonso wamorphoous ndi mawonekedwe a mankhwala a Msio2.h2o. Ndizopanda thupi m'madzi ndi ena ma sol sol, osakhala ndi zolaula komanso osasangalatsa, ndipo sizikugwirizana ndi zinthu zilizonse zokhala ndi alkali ndi hydrofluoric acid. Amagwiritsidwanso ntchito kwambiri ndipo itha kugwiritsidwa ntchito ngati njira yapadera ya ndege, ndi madipatimenti ankhondo, komanso mapepala, mankhwala, mankhwala ndi chithandizo chamankhwala.
Makhalidwe ndi kugwiritsa ntchito siketi ya silika.
1. Mawonekedwe a Proble: Imakhala ndi magwiridwe antchito, kukalamba, kutseka makone komanso kulimba mtima komanso nyonga yabwino. Ndiwopanda kutentha kwa chipinda chimodzi. Mkati mwa kutentha kwa ℃, sipadzakhala zovuta pakugwiritsa ntchito kwa nthawi yayitali.
2. Kugwiritsa ntchito mankhwala: Kugwiritsa ntchito kwakukulu kwa rabara silika ndikutchingira, chinyezi, cholumikizira, zida zotsutsana ndi zomangira za Semisotoctor, zida zamagetsi ndi zida zina; Amagwiritsidwanso ntchito pabwalo la ndege, zida zankhondo, zida zosindikizira zomwe zimagwiritsidwa ntchito pazomwe zimachitika mu makina. Izi ndi zinthu zabwino kwambiri zomatira ndi zitsulo zomatira monga kuyendetsa ndege, zamagetsi, ndi kupanga zamagetsi.
3. Malangizo ogwiritsira ntchito malonda
a. Pamwamba pa chinthucho chikuyenera kutsukidwa koyamba, ndipo dzimbiri, fumbi, mafuta, etc. iyenera kutsukidwa kaye;
b. Kenako yambitsani gluing, ikani payipi ya pulasitiki, ikani mphuno ya pulasitiki, kenako ikani kukula koyenera ndi tsamba kuti mutsegule guluu ndi udindo wofunikira;
c. Nditagwiritsidwa ntchito, gawo lotsatira ndikudikirira kuchiritsa, kenako ndikuyika magawo ophikira ndikudikirira kuchiritsa. Pochiritsa, amachiritsidwa kuchokera kunja mpaka mkati. Kuzama kwa guluu ndi 2-4mm. Imafunika kuchiritsidwa mkati mwa maola 24 ndipo chinyezi ndi 55%. Ngati kuya kupitiliraku, nthawi idzakhala yotalikirapo. Mtengo wotsika adzapitikitsa nthawi yochiritsa.
