Layin Fitar Bututu Mai Girma Mai Girma HDPE

Bututun HDPE wani nau'in bututun filastik ne mai sassauƙa da ake amfani da shi don canja wurin ruwa da iskar gas kuma galibi ana amfani da shi don maye gurbin bututun siminti ko ƙarfe da suka tsufa. An yi shi da thermoplastic HDPE (polyethylene mai yawan yawa), babban matakin rashin ruwa da haɗin kwayoyin halitta mai ƙarfi ya sa ya dace da bututun mai mai matsin lamba. Ana amfani da bututun HDPE a duk faɗin duniya don amfani kamar bututun ruwa, bututun iskar gas, bututun magudanar ruwa, layukan canja wurin slurry, ban ruwa na karkara, layukan samar da wutar lantarki, bututun lantarki da sadarwa, da bututun ruwa da magudanar ruwa.

Manyan bututun HDPE masu diamita suna da ƙarfi, masu sauƙi, masu jure wa girgiza kuma suna jure wa sinadarai. Suna ba da isasshen amfani ga shigarwa da tsawon rai. Waɗannan bututun suna samuwa a tsayin mita 3, 6, 12 da 14. Ana iya samar da tsayin bututu na musamman don biyan kusan kowace buƙata.

Bututun HDPE bututu ne mai sassauƙa wanda aka yi da polyethylene mai yawan zafi da zafi wanda ake amfani da shi sosai don jigilar ruwa da iskar gas mai ƙarancin zafi. A cikin 'yan lokutan nan, bututun HDPE sun sami amfani mai yawa don ɗaukar ruwan sha, sharar gida mai haɗari, iskar gas daban-daban, slurry, ruwan wuta, ruwan sama, da sauransu. Ƙarfin haɗin kwayoyin halitta na kayan bututun HDPE yana taimaka masa wajen amfani da bututun mai mai ƙarfi. Bututun Polyethylene suna da dogon tarihi na sabis na iskar gas, mai, hakar ma'adinai, ruwa, da sauran masana'antu. Saboda ƙarancin nauyi da juriyar tsatsa, masana'antar bututun HDPE tana bunƙasa sosai. A shekarar 1953, Karl Ziegler da Erhard Holzkamp sun gano polyethylene mai yawan yawa (HDPE). Bututun HDPE na iya aiki mai gamsarwa a cikin kewayon zafin jiki mai faɗi na -2200 F zuwa +1800 F. Duk da haka, ba a ba da shawarar amfani da Bututun HDPE ba lokacin da zafin ruwan ya wuce 1220 F (500 C).

Ana yin bututun HDPE ta hanyar polymerization na ethylene, wani abu da aka samo daga mai. Ana ƙara ƙarin abubuwa daban-daban (masu daidaita, masu cikawa, masu plasticizers, masu laushi, mai, masu launi, masu hana harshen wuta, masu busawa, masu haɗa abubuwa, ƙarin abubuwa masu lalacewa ta ultraviolet, da sauransu) don samar da bututun HDPE na ƙarshe da abubuwan haɗin. Ana yin tsawon bututun HDPE ta hanyar dumama resin HDPE. Sannan ana fitar da shi ta cikin injin, wanda ke ƙayyade diamita na bututun. Kauri na bangon bututun ana ƙayyade shi ta hanyar haɗa girman manne, saurin sukurori, da saurin tarakta mai ɗaukar kaya. Yawanci, ana ƙara kashi 3-5% na baƙin carbon a cikin HDPE don ya zama mai jure UV, wanda ke mayar da bututun HDPE zuwa launin baƙi. Sauran bambance-bambancen launi suna samuwa amma yawanci ba a amfani da su akai-akai. Bututun HDPE mai launi ko mai layi yawanci shine kayan baƙi 90-95%, inda aka samar da tsiri mai launi akan kashi 5% na saman waje.
