Kupulumutsa mphamvu ndi kuteteza chilengedwe, ntchito zagalasi zonyansa ndi ziti?

Ngakhale kuchuluka kwachuma padziko lonse lapansi kukukulirakulira, kutsutsana pakati pa chilengedwe chazachuma ndi chitukuko cha zachuma ndi chikhalidwe cha anthu kukukulirakulira.Kuipitsa chilengedwe kwasanduka vuto lalikulu la padziko lonse.Monga makampani opanga magalasi, tingathandize chiyani pachitetezo cha chilengedwe padziko lonse lapansi?

Magalasi otayika amasonkhanitsidwa, amasanjidwa, ndikukonzedwa, ndipo amagwiritsidwa ntchito ngati zopangira magalasi, zomwe zakhala njira yayikulu yobwezeretsanso magalasi otayira.Magalasi otayira angagwiritsidwe ntchito popanga zinthu zamagalasi zomwe zimakhala ndi zofunikira zochepa pakupanga mankhwala, mtundu ndi zonyansa, monga galasi lamitundu yamabotolo, zotsekera magalasi, njerwa zamagalasi zopanda kanthu, magalasi anjira, magalasi opangidwa ndi magalasi achikuda ndi mipira yamagalasi achikuda.Kusakaniza kwa magalasi otayirira muzinthu izi nthawi zambiri kumakhala kopitilira 30wt%, ndipo kuchuluka kwa zinyalala zamagalasi mu botolo lobiriwira ndipo zimatha kufikira kupitilira 80wt%.

Kugwiritsa ntchito galasi lotayirira:
1. Zida zokutira: gwiritsani ntchito magalasi otayira ndi matayala otayira kuti aphwanyidwe kukhala ufa wabwino, ndikusakaniza mu utoto mu gawo linalake, lomwe lingalowe m'malo mwa silika ndi zipangizo zina mu utoto.
2. Zopangira magalasi-ceramics: magalasi-ceramics ali ndi mawonekedwe olimba, mphamvu zamakina apamwamba, mankhwala abwino komanso kukhazikika kwamafuta.Komabe, mtengo wopangira zinthu zachikhalidwe zomwe zimagwiritsidwa ntchito muzovala zamagalasi ndizokwera kwambiri.M'mayiko akunja, magalasi otayira kuchokera kumayendedwe oyandama ndi phulusa lowuluka kuchokera kumagetsi amagwiritsidwa ntchito m'malo mwa zida zamagalasi-ceramic zopangira kuti apange magalasi-ceramics bwino.
3. Asphalt wagalasi: gwiritsani ntchito galasi lotayirira ngati chodzaza misewu ya phula.Ikhoza kusakaniza magalasi, miyala, ndi zoumba popanda kusankha mitundu.Poyerekeza ndi zipangizo zina, kugwiritsa ntchito galasi ngati chodzaza misewu ya asphalt kuli ndi ubwino wambiri: kupititsa patsogolo ntchito yotsutsa-skid panjira;kukana abrasion;kuwongolera kuwunikira kwapanjira ndikuwonjezera mawonekedwe owoneka bwino usiku.
4. Glass mosaic: Njira yogwiritsira ntchito galasi lotayirira kuti liwotche mwachangu magalasi agalasi, omwe amadziwika ndi kugwiritsa ntchito galasi lotayirira ngati chinthu chachikulu, pogwiritsa ntchito chomangira chatsopano (amadzimadzi a guluu), zopaka utoto komanso seti yathunthu yofananira. njira za sintering.Kuthamanga kwamapangidwe ndi 150-450 kg / cm2, ndipo kutentha kochepa kwambiri ndi 650-800 ℃.Amawotchedwa mumsewu wosalekeza wamagetsi.Palibe choletsa thovu chofunikira;chifukwa cha ntchito yabwino ya binder, ndalamazo ndizochepa, ndipo zimatha kuthamangitsidwa mwamsanga.Zotsatira zake, mankhwalawa ali ndi mitundu yosiyanasiyana, palibe thovu, malingaliro amphamvu komanso mawonekedwe abwino kwambiri.
5. Marble Opanga: Marble opangira amapangidwa ndi magalasi otayirira, phulusa la ntchentche, mchenga ndi miyala monga zophatikizira, simenti imagwiritsidwa ntchito ngati chomangira, ndipo wosanjikiza wapamtunda ndi maziko ake amagwiritsidwa ntchito popangira machiritso achilengedwe.Sizingokhala ndi mawonekedwe owala komanso mtundu wowala, komanso zimakhala ndi zinthu zabwino zakuthupi komanso zamakina, kukonza kosavuta komanso kukongoletsa bwino.Iwo ali ndi makhalidwe a magwero lonse yaiwisi, zipangizo zosavuta ndi luso, mtengo wotsika, ndi ndalama otsika.
6. Matailosi agalasi: gwiritsani ntchito magalasi otayira, zinyalala zadongo monga zida zazikulu, ndi moto pa 1100°C.Magalasi otayira amatha kutulutsa gawo lagalasi mu matailosi a ceramic koyambirira, komwe kumapindulitsa kuzizira ndikuchepetsa kutentha kwamoto.Tile yagalasi imeneyi imagwiritsidwa ntchito kwambiri pokonza mabwalo a m'tauni ndi misewu ya m'tauni.Sizingalepheretse madzi amvula kusonkhanitsa ndi kusunga magalimoto, komanso kukongoletsa chilengedwe ndikusandutsa zinyalala kukhala chuma.
7. Ceramic glaze zowonjezera: Mu glaze ya ceramic, kugwiritsa ntchito galasi lotayirira m'malo mwa frit yamtengo wapatali ndi zinthu zina zopangira mankhwala sikungathe kuchepetsa kutentha kwa glaze, kuchepetsa mtengo wa mankhwala, komanso kupititsa patsogolo khalidwe la mankhwala. .Kugwiritsira ntchito magalasi akuda kuti apange glaze kungathenso kuchepetsa kapena kuthetsa kufunika kowonjezera mitundu, kotero kuti kuchuluka kwa ma oxides achikuda kuchepetsedwa, ndipo mtengo wa glaze umachepetsanso.
8. Kupanga zida zopangira matenthedwe ndi zida zotulutsa mawu: magalasi otayira amatha kugwiritsidwa ntchito popanga zida zoziziritsa kukhosi komanso zida zotulutsa mawu monga magalasi a thovu ndi ubweya wagalasi.
