Zipangizo kutchinjiriza kwa mapaipi zopangidwa thovu polyethylene: kukula, makhalidwe, zithunzi

Pamene atagona ndi ntchito mapaipi a mtundu uliwonse ankafunika kopita kuchita malamulo, mwinamwake mungapeze mitundu yonse ya mavuto.

kufunika kokhala

Kuchimbudzi ndi madzi mipope, zomwe zili kunja kapena mkati zipinda unheated, mukhoza amaundana. Pankhani dongosolo Kutentha, ayenera kupewa kutentha imfa, komanso kukhalabe kutentha ena a coolant lapansi. Chitetezo milandu anafotokoza ntchito heaters kwa mapaipi zopangidwa thovu polyethylene.

Features Ofunika

Tangotchulawo chuma ali ndi dongosolo lapadera tichipeza maselo ang'onoang'ono losindikizidwa, kachulukidwe wake ndi wofanana ndi chithunzi mu osiyanasiyana kuchokera makilogalamu 25 40 pa mita kiyubiki. Polyethylene ali elasticity kwambiri ngakhale atadziŵa otsika kutentha, ndi katundu sakusintha pa osiyanasiyana pakati -60 ndi +90 madigiri. Izi zikusonyeza kuti kutchinjiriza kwa mapaipi zopangidwa thovu polyethylene angathe kuikidwa pansi pa zikhalidwe aliyense nyengo. Foamed polyethylene kutchinjiriza koyefishienti mkulu mokwanira, popeza madutsidwe matenthedwe ndi otsika ndi zimasiyanasiyana 0,038 kuti 0,039. Madzi nthunzi permeability ndi 0,001, amene amalola zinthu kuonetsa khalidwe la wathunthu nthunzi kukana. Ndi phunziro kwa katundu osiyanasiyana, monga chachikulu cha izi ndicho chithunzi cha 0,3 MPa. Kutchinjiriza kwa mapaipi madzi a thovu polyethylene ali mayamwidwe phokoso lomwe 16 decibels, kotero chuma excellently zimatenga phokoso ndi Phokoso amene angakhalepo pa ntchito kachitidwe payipi. Tikumbukenso ndi hydrophobicity kwambiri Choncho mu mwachindunji kukhudzana ndi madzi akhoza kukhala odzipereka pa otsiriza 1% buku okwana. Mlingo wapamwamba wa mayamwidwe madzi ndi 3.5%. N'chifukwa chake makongoletsedwe sizikutanthauza kufunika ntchito kumatira, kuyambira pamwamba sadzakhala kupanga condensate. Kutentha kutchinjiriza kwa mapaipi zopangidwa thovu polyethylene excellently kulimbana ndi chikoka cha zinthu mankhwala yogwira mtundu wa mafuta, mafuta, zidulo ndi alkalis.

mbali zina

Anafotokoza kutchinjiriza amapangidwa malinga ndi GOST 30244-94. Foamed polyethylene akhoza wachinsinsi zipangizo monga amtengo kuyaka, kutentha poyatsira mu mwachindunji lawi kukhudzana madigiri 306. Pakuti kudziletsa poyatsira ndi madigiri 416 chikukwanira. Komabe, amaona mwayi zina kutchinjiriza si poizoni ngakhale pamene moto, pochita zilibe zimatulutsa nthunzi zoipa m'thupi la munthu.

makhalidwe abwino

Ngati mukufuna kutchinjiriza kwa mapaipi lopangidwa ndi thovu polyethylene, muyenera kuganizira ubwino wake onse. Nthawi zambiri, chuma poyerekeza ndi polystyrene thovu ndi polyurethane thovu, kotero kusiyanitsa ubwino ambiri mwa iwo - pang'ono matenthedwe madutsidwe, imene n'zotheka kupereka chisindikizo ogwira amene ali makulidwe yaing'ono. Tikumbukenso, ndipo chotero khalidwe monga kulimba kwamakokedwe, komanso luso kwambiri kubwezeretsa mtundu koyamba pambuyo mapindikidwe. Pa chithovu zingakhudzire simenti, gypsum, laimu ndi simenti, mopanda tsankho kwa makhalidwe Mkhalidwe. Chifukwa kuti chotenthetsera kuwuluridwa kwathunthu vuto lililonse, osati anthu komanso chilengedwe, izo amaloledwa kugwiritsa ntchito makampani, panyumba, zipatala ndi masukulu makampani chakudya. Polyethylene ali ndi makhalidwe a hydrophobicity kuti amalenga kuti kuthetsa pakutchulidwa nkhungu ndi cinoni. Tikumbukenso, ndi omasuka unsembe, T. Kwa. Zamgululi mwa mawonekedwe a machubu dzenje amene angagwiritsidwe ntchito kwa nthawi yochepa Kumalimbikitsa chitoliro, pogwiritsa ntchito zipangizo zina ndi zida kwa cholinga ichi. mtengo zakuthupi nthawi 2 m'munsi poyerekeza ndi njira zofanana, nchifukwa chake mtundu wa kutchinjiriza ntchito ndi ogula ayamba.

Ena mwa makhalidwe oipa

Matenthedwe kutchinjiriza kwa mapaipi zopangidwa thovu polyethylene, makhalidwe a zimene zili m'nkhani, ali zina zabwino mwa iwo, monga momwe tafotokozera pamwambapa, luso kuchirikiza kuyaka ndi flammability pamene lawi kukhudzana. Pachifukwa chimenechi, nkhani kugwiritsa ntchito pa malowa kuti adzakomane amafuna chitetezo mkulu moto. Mwazina, thovu n'kugwa mchikakamizo cha dzuwa. Izi zikusonyeza kufunika kwa kusunga ndi kukhala chitoliro kutchinjiriza mu malo amenewo kumene amachotsedwa kolowa ultraviolet. Kuti athetse vutoli, chuma amusankha amene ali ndi opaque filimu. Zolakwa mosavuta kulipidwa ndi ubwino tatchulawa.

Makulidwe ndi zina zokhudza zina

Ngati inu kusankha kugwiritsa ntchito kutchinjiriza kwa mapaipi lopangidwa ndi thovu polyethylene, kukula kwa amene akhoza zimasiyana 6 160 mm, m'pofunika kudziwa mitundu yonse ya diameters ake. Choncho, khoma makulidwe akhoza kukhala wofanana ndi chiwerengero mu osiyanasiyana sikisi millimeters makumi awiri. msika mungapeze chitoliro kutchinjiriza, omwe amaperekedwa ndi Kakhungu yapadera, ndi wachikuda polymeric ❖ kuyanika. Iwo amateteza dzuwa kukhudzana, amene amalola ntchito mankhwala amenewa, ngakhale malo amene kaŵirikaŵiri ndi kuwala. Mwazina, kutchinjiriza kwa mapaipi zopangidwa thovu polyethylene, zomwe zithunzi ali zili m'nkhani mwina pepala kapena mpukutu. Nthawi zina m'nyengo kupanga kapena kutchinjiriza lowonjezera analepheretsa zomatira.

Kapangidwe ka mthunzi

mawonekedwe kudzipatula zofunika kuzikwaniritsa kuti kuwalola amuzungulire pamwamba ndi mipata kochepa. zakuthupi sayenera olumala, ndi mawonekedwe ayenera awiri ena. Only m'njira imeneyi kupezera muyeso kwambiri za kutchinjiriza. Kuonetsetsa zosavuta unsembe pamodzi chubu, monga ulamuliro, ndi ang'ambe thupilo zamakono, amene amalola kuti unsembe ntchito mu nthawi yaifupi zotheka ndi machitidwe amene anaika kale.

Features unsembe

Ngati mukufuna kugwiritsa ntchito kwa kutchinjiriza, kutchinjiriza kwa mipope zopangidwa thovu polyethylene, m'mimba m'pofunika kusankha wangwiro kwambiri. Pambuyo pake, ndikofunika kutsatira unsembe wa kutchinjiriza luso. Machubu asasanyika ndondomeko, ndi pamwamba ndi kutsukidwa ku dothi ndi fumbi. Polyethylene ndi kuvala mtundu kuwonjezera sitiyenera kugwirizana ndi mavuto makamaka. Izi zikhoza kuchitika pa chitoliro sanayambebe anaika, kutchinjiriza sadzaweruzidwa kuonongeka ndi mpeni.
