Polypropylene mapaipi madzi otentha - kusankha chimake akadakwanitsira

Tikukonza kapena kukonza lalikulu kunyumba kwawo pafupifupi aliyense ali kusankha chitoliro makonzedwe a dongosolo mkulu ndi odalirika kulankhulana. Modern zomangira msika muli zosiyanasiyana zimene mungachite, monga polypropylene chubu (mtengo, ndi Dziwani, yokondweretsa kwambiri), zitsulo ndi zitsulo mankhwala, ndi zambiri. Koma ena mwa iwo wanji? Nkhani imeneyi posachedwapa kukhala zogwirizana kwambiri.

M'mbuyomo zoweta otentha madzi ntchito kokha machubu zitsulo kuti anali kukonza pafupifupi chaka chilichonse. Koma chifukwa umisiri watsopano mwayi kugwiritsa ntchito zipangizo bwino. Ali ndi moyo wautali utumiki ndipo amaonedwa yosafuna zambiri, chifukwa sikutanthauza kupenta ndi kusamalidwa. Mmodzi wa options wotchuka kwambiri tsopano polypropylene mapaipi madzi otentha. mtundu uwu ndi abwino kwa malo, ndi zofunikira apadera kutentha ndi mlingo wa chinyezi kumeneko. machubu polypropylene angathe kuikidwa nyumba, mafakitale nyumba (mafakitale, zomera) mu kukatentha, ndipo ngakhale zapansi. Ndi chifukwa cha katundu ntchito chuma mphothoyi kwambiri cha kutchuka pomanga mbadwo watsopano wa aya.

makhalidwe luso

Mpaka ndi posachedwapa, zinthu zinali achilendo osiyanasiyana ogula. Komabe, mu nthawi yaifupi zotheka zonse wasintha kwambiri. Makamaka, omanga akatswiri analimbikitsa makasitomala awo kukhazikitsa chabe mankhwala amenewa. ndi ubwino wotani? Kuti tiyankhe funso limeneli, m'pofunika kuphunzira mwatsatanetsatane, umene ndi polypropylene chubu.

Zofunika (magawo chachikulu):

• Kutentha mphamvu - 1,75 KJ / kg ⁰ C.
• Kupititsa patsogolo liniya - 3,5 ÷ 10 ^{-5 (1/0} C).
• Chofanana roughness koyefishienti - 0,015 mm.
• The pazipita index kwamakokedwe mphamvu - 35 MPa.
• Matenthedwe madutsidwe - 0,15 W m / ⁰ C.
• Kachulukidwe - 0,989 g / mamita ^3.
• Anzanu - 25 bar.
• Indicators wa pazipita mavuto - 30 MPa.
• kuwotcherera nthawi - masekondi 4-8.

Ubwino polypropylene machubu

Pogula mipope polypropylene ayenera kuwaganizira yofunika chizindikiro - ndi koyefishienti cha kuwonjezedwa matenthedwe. The madutsidwe matenthedwe wa propylene ndi zitsulo zosiyana. Amadziwika kuti mankhwala zitsulo ndi womvera kusintha mwadzidzidzi kutentha. Mwachitsanzo, ngati nthawi yaitali chitoliro ndi kulanditsa madzi otentha, kenako mwadzidzidzi anapita ozizira, ndiye kuchiwonongeko mofulumira. Mwamwayi, mapaipi polypropylene chifukwa cha kuchuluka kochepa zitsulo mu ndondomeko imeneyi si bwanji, ndikulora iwo kuti akhale nthawi yaitali kwambiri ndi molondola.

Choncho, ife kuganizira za ubwino waukulu wa mankhwala:

• mkulu mphamvu;
• durability, moyo utumiki oposa zaka 50;
• GOST PN20 polypropylene chubu ambike ngakhale pamene madzi amaundana;
• tisaletse unsembe, ndi kuika aya akhoza kusamalira munthu mmodzi;
• kudalirika;
• Iwo ali koyefishienti mkulu wa kukana hayidiroliki ;
• kukana kusinthasintha lalikulu kutentha, madzi Kutentha kungakhale madigiri mpaka 100;
• kusinthasintha zabwino;
• Ndi kugonjetsedwa ndi dzimbiri;
• luso kukuza pansi zochita za kutentha.

mfundo

Polypropylene mapaipi madzi otentha ndi cholukanalukana ntchito zovekera kapena zovekera atolankhani. Zimenezi zimathandiza kuti apamwamba soldering ndi kugwirizana kwa kuchucha, okhoza kugwira zaka zoposa khumi.

Zikusonyezanso kuti madzi ndi pokhudzana ndi chitoliro polypropylene, amasunga zikutsatiridwa akuphatikizapo maselo, umene uli wofunika kwa thanzi la munthu.

Features ya kapangidwe mkati

Ochiritsira polypropylene chubu ndi kapangidwe ka zigawo zitatu, motero kuonetsetsa durability mkulu ndiponso kudalirika kwa dongosolo lonse. Awiri a iwo ndizo zikuluzikulu ndipo wina - pakati. Iye amachita monga usawonongeke. The mkati ndi kunja wosanjikiza anapangidwa ndi polypropylene ndi sing'anga - yaing'ono makulidwe zopangidwa zotayidwa kapena fiberglass.

Chifukwa kusinthasintha mkulu wa zipangizo polypropylene mapaipi madzi otentha zimakhala zosavuta kukhazikitsa ndi n'zotheka kusintha malangizo a magetsi kapena kuikira. The M'kati ali yosalala pamwamba kuti si kulenga chopinga chilichonse kwa kufalitsa madzi.

mtengo wa

machubu otere nthawi zambiri aziwapatsa kumalo yaitali, umene pa unsembe pafupifupi sumangoyambika zimfundo ndi kugwirizana. Modern mankhwala kulankhulana ndi mosalekeza, kotero iwo akhoza kugwiritsidwa ntchito ponena za kunja ndi kachitidwe mkati. Polypropylene (mtengo - 20 rubles pa 1 mita) zotsika mtengo kwambiri yokha, koma unsembe ayenera kuganizira kufunika kwa zinthu zonse polumikiza, komanso mfiti. Mulimonsemo, yaitali ntchito m'magulu otere m'tsogolo adzalola kupulumutsa kwambiri pa kukonza.

Zedi, aliyense kuyesera kulenga m'nyumba yake mlingo pazipita chitonthozo ndi mayiko, choncho kuyang'ana kwa zipangizo zambiri zamakono zapamwamba dongosolo nyumba. Popeza madzi ndi chimodzi cha zigawo zikuluzikulu zofunika kwambiri wa chitonthozo, kwambiri ndi kwambiri linaperekedwa kwa dongosolo lino zomangamanga. Choncho analimbikitsa kukhazikitsa mipope polypropylene madzi otentha. Ndipo mtengo ndi cholimba.
