Babban Diamita HDPE Layin Extrusion Bututu

HDPE bututu nau'i ne na bututun filastik mai sassauƙa da ake amfani da shi don canja wurin ruwa da iskar gas kuma ana amfani da shi sau da yawa don maye gurbin bututun siminti ko ƙarafa.An yi shi daga thermoplastic HDPE (polyethylene mai girma mai yawa), babban matakin rashin ƙarfi da haɗin kai mai ƙarfi ya sa ya dace da bututun matsa lamba.Ana amfani da bututun HDPE a duk faɗin duniya don aikace-aikace kamar hanyoyin ruwa, manyan iskar gas, magudanar ruwa, layukan canja wuri, ban ruwa na karkara, layin samar da wutar lantarki, wutar lantarki da hanyar sadarwa, da ruwan sama mai ƙarfi da bututun magudanar ruwa.

Manyan diamita na HDPE bututu suna da tauri, marasa nauyi, girgiza da juriya na sinadarai.Suna bayar da tattalin arzikin shigarwa da kuma tsawon rayuwar sabis.Wadannan bututu suna samuwa a daidaitattun tsayin 3, 6, 12 da 14m.Ana iya samar da tsayin bututu na musamman don saduwa da kusan kowace buƙata.

HDPE bututu ne m roba bututu sanya na thermoplastic high-yawa polyethylene yadu amfani ga low-zazzabi ruwa da gas canja wuri.A cikin 'yan sau, HDPE bututu samu su m amfani ga dauke ruwa ruwa, m sharar gida, daban-daban gas, slurry, wuta ruwa, hadari ruwa, da dai sauransu A karfi kwayoyin bond na HDPE bututu kayan taimaka shi don amfani da high-matsi bututun.Bututun polyethylene suna da dogon tarihin sabis na musamman don iskar gas, mai, ma'adinai, ruwa, da sauran masana'antu.Saboda ƙarancin nauyi da juriya mai girma, masana'antar bututun HDPE tana girma sosai.A cikin 1953, Karl Ziegler da Erhard Holzkamp sun gano polyethylene mai girma (HDPE).HDPE bututu na iya yin aiki mai gamsarwa a cikin kewayon zafin jiki mai faɗi -2200 F zuwa + 1800 F. Duk da haka, ba a ba da shawarar yin amfani da bututun HDPE lokacin da yawan zafin jiki ya wuce 1220 F (500 C).

Ana yin bututun HDPE ta hanyar polymerization na ethylene, samfurin mai.Daban-daban Additives (stabilizers, fillers, plasticizers, softeners, lubricants, colorants, harshen wuta retardants, hurawa jamiái, crosslinking jamiái, ultraviolet m Additives, da dai sauransu) an kara don samar da karshe HDPE bututu da aka gyara.Ana yin tsayin bututun HDPE ta hanyar dumama guduro HDPE.Sannan ana fitar da shi ta hanyar mutuwa, wanda ke ƙayyade diamita na bututun.An ƙayyade kauri na bangon bututu ta hanyar haɗuwa da girman mutuwa, saurin dunƙule, da saurin tarakta mai ɗaukar hoto.Yawancin lokaci, 3-5% carbon baƙar fata yana ƙara zuwa HDPE don sanya shi juriya ta UV, wanda ke juya bututun HDPE zuwa launin baki.Wasu bambance-bambancen launi suna samuwa amma yawanci ba a yi amfani da su akai-akai ba.Bututun HDPE mai launi ko taguwa yawanci 90-95% baƙar fata ne, inda aka ba da ratsin launi akan 5% na farfajiyar waje.
