Kugwiritsa ntchito gulu la thanki la madzi la SMC

Zipangizo zopangidwa ndi SMC, mtundu wa pulasitiki wolimbikitsidwa ndi ulusi wagalasi. Zipangizo zazikulu zimapangidwa ndi GF (ulusi wapadera), MD (wodzaza) ndi zinthu zina zothandizira. Zinayamba kuonekera ku Europe kumayambiriro kwa zaka za m'ma 1960, ndipo cha m'ma 1965, United States ndi Japan zinapanga luso limeneli motsatizana. Kumapeto kwa zaka za m'ma 1980, dziko lathu linayambitsa njira zopangira zinthu zakunja za SMC komanso njira zopangira.

Kapangidwe kapadera ka zinthu zopangidwa ndi SMC kamathetsa zofooka za mabokosi a matabwa, zitsulo ndi pulasitiki omwe ndi osavuta kukalamba, osavuta kuwononga, osateteza kutentha, osazizira bwino, osachedwa kuyaka moto, komanso amakhala ndi moyo waufupi. Magwiridwe antchito, oletsa dzimbiri, oletsa kuba, osafunikira waya wothira pansi, mawonekedwe okongola, chitetezo chachitetezo chokhala ndi maloko ndi zisindikizo za lead, nthawi yayitali yogwira ntchito, mabulaketi a chingwe chophatikizika, mabulaketi a ngalande za chingwe, mabokosi a mita yophatikizika, ndi zina zotero amagwiritsidwa ntchito kwambiri mumagetsi a ulimi. Amagwiritsidwa ntchito pomanganso netiweki ya m'mizinda.

Thanki yamadzi ya SMC imasonkhanitsidwa pamalopo ndi mbale zoumbidwa ndi SMC, zipangizo zotsekera, zida zachitsulo ndi mapaipi. Zimabweretsa zosavuta kupanga ndi kumanga. Thanki yamadzi yonse imapangidwa molingana ndi muyezo, ndipo thanki yapadera yamadzi iyenera kupangidwa mwapadera. Matanki amadzi okwana 0.125-1500 cubic metres amatha kusonkhanitsidwa malinga ndi zosowa za ogwiritsa ntchito. Ngati thanki yoyambirira yamadzi ikufunika kusinthidwa, palibe chifukwa chokonzanso nyumbayo, ndipo kusinthasintha kwake kumakhala kolimba kwambiri. Tepi yotsekera yopangidwa mwapadera yazinthu zodziwika bwino, zomwe sizili ndi poizoni, sizimamwa madzi, sizimatambasuka, zimakhala zochepa komanso zimasinthasintha, komanso zimatsekedwa bwino. Mphamvu yonse ya thanki yamadzi ndi yayikulu, palibe kutuluka kwa madzi, palibe kusintha, ndipo kukonza ndi kukonza ndikosavuta.

Bolodi la thanki la madzi lopangidwa ndi SMC limapangidwa ndi zinthu zolimbitsa ulusi wagalasi ndipo limapangidwa ndi kutentha kwambiri komanso njira yopanikizika kwambiri. Kukula kwa mbale ndi 1000 × 1000, 1000 × 500 ndi 500 × 500 mbale zitatu zokhazikika, makulidwe a mbale ndi 6mm, 8mm, 10mm, 12mm, 14mm, 16mm.
