Layin Fitar da Bututun Silicon Shafi

Layin samarwa zai iya samar da bututun tushe da yawa a lokaci guda, yana sassauta sauri, kuma yana rufe murfin waje cikin sauri da daidaito. Kwamfuta ce ke sarrafa jan hankali, yankewa da naɗewar samfurin da aka gama, tare da saurin samarwa da inganci mai yawa.

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.
