Pereka denga zipangizo. Ubwino, kuipa, ndi mitundu ikuluikulu ya

Pereka denga zipangizo ankagwiritsa ntchito mu zida mwa denga. Denga la izi ndi chimodzi mwa zinthu zotsika mtengo komanso yosavuta sayansi kupanga. Ngakhale cheapness wachibale, ngati luso zinayi wosanjikiza ❖ kuyanika zakuthupi denga adzakhala yemweyo monga ndi chitsulo denga la kanasonkhezereka zitsulo. Komabe, padenga la zinthu denga ali choonekera drawback - kwambiri flammable.

Zipangizo zofewa denga zakhala zikuzunza m'miyoyo zigawo zingapo, omwe amanyamula ntchito yeniyeni. Backsheet ndi uncoated chuma (akalowa), ndi chapamwamba - coverslips. Mbali yaikulu ya mumalize nkhaniyo - ndi pamaso pa wosanjikiza munali posypku (fumbi ngati, chabwino-grained kapena coarse-grained) ndi refractory phula.

The zambiri ntchito mayina denga zipangizo - ndi phula, denga anamvera ndi chuma denga. Iwo zosavuta woyenera. Iwo ntchito pa madenga ndi otsetsereka pang'ono pa limodzi chidutswa m'munsi.

Mmodzi wa katundu waukulu zipangizo zofewa denga - madzi zosagwira. Mundawu anakhalabe yekha pa kukhulupirika konse kwa nkhani ya, i.e. pakalibe misozi ndi ming'alu.

Padenga kupeza quality, cholimba, zipangizo mpukutu denga ayenera kukumana mfundo zotsatirazi:

• Kuswa mphamvu (chuma chinang'ambika n'kupanga wa masentimita 5, ndi khama kwambiri motero ntchito, mphamvu chuma);
• zakuthupi kukaniza kutentha;
• kusinthasintha kwa zinthu anali ayesedwa ndi yozizira kwambiri limene palibe ming'alu pa unakhota wa ndodo.

Denga zipangizo. mitundu

Malinga gawo lapansi, zida ndi zipangizo mpukutu denga Pali mitundu zotsatirazi:

• pa dongosolo chinsalu - zikuluzikulu ndi mabodza;
• zigawo mtundu wa zikuchokera ❖ kuyanika - polima, phula, phula polima;
• ndi maziko mtundu - zikatoni, asibesitosi, fiberglass, pulasitiki ndi gulu;
• mu kapangidwe ka wosanjikiza atetezeke - ndi zojambulazo kapena filimu, ndi flake, pulverized, coarse, chabwino-grained.

Komanso, malingana binders, iwo ali polima-phula kapena phula.

Bituminous denga zipangizo ndi mitengo otsika ndi khalidwe kuchepetsa sravneniiyu ndi polima-phula. The sangathe ndi otsika chisanu kukana. Komabe, chuma ichi kawirikawiri amagwiritsidwa ntchito kwa kapangidwe mkati mwa kumatira chifukwa kukana chinyezi.

Polima-phula denga mpukutu zipangizo ndi mapindu kuposa anthu m'mbuyomo. Komabe, mtengo ndi apamwamba. Ali ndi digiri yapamwamba ya durability ndi zodalirika, kugonjetsedwa ndi kutentha kwambiri ndi otsika. makhalidwe amenewa ndi yofunika kwambiri kusankha zipangizo denga kwa nkhanza nyengo ya dziko lathu. zinthuzi ukhoza kwa zaka pafupifupi 25, nkhani kuti luso yopanga ndi kuyala denga.

Ndi osiyanasiyana okwanira denga zinthu phula polima mayina ndi mawu atsopano mu masiku ano denga chophimba. Komabe, posankha muyenera eni zofunika ndi kusankha chimene chili chofunika kwambiri: mtengo kapena khalidwe liti?
