Ducts yeplastiki - marudzi uye maitiro

Kuputika kwechivako chechivako chero chipi zvacho chinogadzirwa nekubatsira kwemhepo. Ndiyo mapaipi anobvumira mweya kupinda mumakamuri. Iyo yakaumbwa nesimbi, aluminium, plastiki. Ducts epurasitiki yakatanga kushanda kwete kare kare. Iyi mashoko ipurasitiki uye haina mari. Vanogona nyore nyore kutora zvivako zvesimbi. Mukuwedzera, vane zvinhu zvakasiyana-siyana pamberi pavo. Ducts yeplasitiki iri nyore kushanda nekuisa. Vane simba rakakwana nekuneta kwechiedza. Uyezve, iyo inodhura. Mukuwedzera, iyo inopikisana nehuroti, inogona kuiswa muimba ine hunyoro hunyoro. Kurwisana nemigumisiro yeAicid and alkalis, iyo inovabvumira kushandiswa munzvimbo ye electroplating mbeu, mumakemikari emabhizimisi, mune imwe nzvimbo yemishonga yemishonga uye yezvokudya. Chipani chepurastiki hachiiti zvinhu zvinokuvadza uye hazvikuvadzi kuhutano hwevanhu. Inowanzoshandiswa kuita kuputika muzvivako zvine vanhu vakawanda. Mafungu emhepo anoita kuti mhepo isanyarare uye yakanyanyisa pamusana pekubwinya kwayo. Kuchengetedza guruva kubva pakuungana pavari, vanobatwa neine antistatic compound. Uye kutakura kwezvivako zvakadaro zviri nyore. Asi madhayisa aya anewo matambudziko avo. Uye, zvichida, iyo huru ndeye plastiki yemafuta.

Rectangular constructions

Kunyanya kakawanda inoshandiswa mumabhizimisi uye muimba yezvigadziro ducts mapurasitiki emakona. Izvo zviri nyore kuisa, nokuti chimiro chavo chinoita kuti zvive nyore kuisa zvikamu kune denga uye masvingo kana kuti kugara pane dzimwe nzvimbo. Kunyanya ivo vanokosha pakugadzirisa mumamiriro ezvinhu akaoma kana munyaya iyo nzvimbo yepakati-chikamu yakakura zvikuru. Izvo zvipfeko zvemufananidzo uyu zvinonyanya kushandiswa pazvinenge zvakabatanidzwa pasi pekufambiswa kwakasimiswa. Iko kune maruva akadai emakona akakomberedzwa, akareba mukati mawo mana zvishoma kudarika upamhi. Kuvakwa kwakadaro kunonzi kupamba. Vanounganidzwa manyore. Nhamo yavo ndeyokuti inofungidzirwa kuti haina ruzha uye inopikisana nekuyerera kwemhepo. Nezvivakwa zvakadaro, pane dzimwe nguva zvinotarisirwa kutenga zvigadzirwa zvinowedzera (somuenzaniso, vatevedzeri, vanonzwika nenzwi).

Ventilation kubva ku polypropylene

Kururamisa kuurayiwa mukati meimba ndechimwe chezvinhu zvikuru zvekugara zvakanaka. Imwe nzira yakaipa ichakurumidza kukuita kuti uzive nezvako pachako nemhepo yakanyorova, inonhuwira, kugunzva mafuta mukicheni. Munzvimbo dzinogara mhepo yehutachiona yakagadzirwa nemapulitiki epurasitiki ichava akanaka kwazvo. Nokuda kwezvinangwa izvi, polyethylene, polypropylene, polyurethane, PVC, silicone uye zvimwe zvimwe zvezvinhu zvakagadzirwa zvinoshandiswa. Ventilating zvivako zvakagadzirirwa ne polypropylene hazvina mvura, kusagadzikana, kusagadzikana kune zvinokonzera mishonga yemakemikari, kune miviri ye ultraviolet. Iva nehupenyu hwehupenyu hwemakore makumi mashanu. Inosangana nekupisa kunotangira -40 kusvika + 85 ° C. Asi kicheni yakanakisisa yakakodzerwa nemidha yakaitwa yePVC yakaitwa yePVC. PVC inonyanya kushandiswa uye ine purasitiki yakanaka. Kubva pane zvimwe zvinhu zvinoratidzwa nehupenyu hurefu hwebasa - kusvika kumakore zana, nehupamhi hwehutsanana.
