Uburyo bwo gukora imiyoboro ya polyethylene nuburyo bwo gukuramo ibikoresho bya granulaire byinjizwa muri extruder nubushyuhe

Umusaruro wa polyethylene

Ibikoresho noneho bitunganywa na screw (inkoni ya spiral) kugirango bisunikwe hanyuma bisohore muri extruder mubibumbano.Ibiryo bitetse nyuma yo kuva mubibumbano, kalibatori yumusaraba hamwe nigitutu cya vacuum byakozwe muburyo bukwiye.Iyo usohotse kuri kalibatori hejuru yubutaka bwamazi arakonja.
Ubushyuhe bwo hejuru bwashongeshejwe polyethylene nyuma yo gukurwa mubibumbano muri vacuum hanyuma buhoro buhoro ibigega bikonjesha bigabanuka ukoresheje amazi akonje.
ibipimo byihariye no gukata.
Ibikorwa byose byakozwe byikora byuzuye nibikoresho bigenzura kandi bikagenzura ubuziranenge bwibicuruzwa byanyuma biremewe kandi izina ryisosiyete nibipimo.
Ibizamini bya Routine byerekana umusaruro wa polyethylene
Ibyiciro byo gupima umusaruro wa PE ni ibi bikurikira:
Gushonga indangagaciro (INSO 6980-1)
Kumenya ubucucike (INSO 7090-1)
Kumenya soot (ISO 6964)
Ikwirakwizwa rya soot (ISO 18553)
Ikizamini cya Tensile (ISO 6259-1,3)
Ikizamini cya hydrostatike (ISIRI 12181-1,2)
Ikizamini cyumuvuduko mwinshi (ASTM D 1599)
Tugarutse ku kizamini cy'ubushyuhe (INSO 17614)
Gupima no kureba amashusho (INSO 2412)
Ikizamini gihamye cyumuriro imbere ya ogisijeni OIT (ISIRI 7186-6)

Gushonga gutemba (INSO 6980-1):
Muri iki kizamini, igipimo cyibintu byashonga bipimwa mugihe cyagenwe nubushyuhe, kubisubizo, uburyo bwo gufata ibikoresho imbere muri extruder bigomba gutekerezwa.
Ikizamini cyibikoresho fatizo (kwemeza ubwiza bwibikoresho) kimwe nibicuruzwa.MFI agaciro k'ibicuruzwa ntigomba kurenza 20% ± ibikoresho fatizo bitandukanye MFI.
• Kumenya ubucucike (INSO 7090-1)
Ubucucike bwibikoresho fatizo nuburyo bwo guhinduranya ibicuruzwa hakoreshejwe uburinganire bwuzuye bwamazi hamwe nubucucike runaka.“Umubare wubucucike bwibicuruzwa, ubwiza bwibikorwa.
• kugena soot (ISO 6964) no gukwirakwiza soot (ISO18553)
Soot mubikoresho fatizo nibicuruzwa byanyuma byagenwe.
Ijanisha ryemewe rya karubone yumukara muri polyethylene umuyoboro wa 2 kugeza 5.2% ugomba kugabanwa neza.

• Kwipimisha (ISO 6259-1,3)
Ukoresheje laboratoire kabuhariwe, imiterere yubukorikori bwa polyethylene, harimo imbaraga nini zirwanya umutwaro wo hanze, kurambura kuruhuka, coefficient ya elastique no gutandukana munsi yimizigo ingingo eshatu zirashobora gupimwa kandi dukurikije ibisubizo byikizamini, dushobora gusuzuma imikorere y'ibicuruzwa mugihe cyo gukora.
Ikizamini cya Hydrostatike (ISIRI 12181-1,2)
Kugirango hamenyekane imbaraga zibicuruzwa birwanya hydrostatike yipimisha., bigashyirwa munsi yumuvuduko wimbere.
Inenge iyo ari yo yose mu byitegererezo (guturika, kubyimba, kubyimba kwaho, kumeneka no kuvunika neza) bivuze ko ibicuruzwa byatsinzwe.
• Ikizamini cyumuvuduko mwinshi (ASTM D 1599)
Muri iki kizamini, umuyoboro w'icyitegererezo ureremba mu cyuzi gifite ubushyuhe buhoraho bwa 23 ° C hanyuma ugashyirwa munsi y’umuvuduko w’imbere, ku buryo igihe kirenze amasegonda 60 kugeza kuri 70, kubyimba hanyuma bigatera gucika.

Tube idacagaguritse cyangwa ngo itere hejuru umwanya muremure ntabwo ari byiza kubikoresha.
Ikizamini cyo gushyushya inyuma (ISO 2505)
Uburebure bugereranije bwa cm 20 z'icyitegererezo muri imwe, hamwe no kuzenguruka ikirere gishyushye (2 ± 110) ° C mu gihe cy'isaha imwe kugeza kuri itatu (ukurikije uburebure bw'urukuta rw'umuyoboro), kandi nyuma yo gukonjesha ni uburebure bw'igituba, bizaba munsi ya imiterere yambere kubushyuhe busanzwe, bushobora kuganisha kumihindagurikire yimyitwarire yashyizwe mumuzinga, bityo ibizamini byavuzwe haruguru bigabanya impinduka ndende (kugeza 3%) muri laboratoire.

• gupima no gusuzuma ibizamini (INSO 2412)
Imiyoboro ya polyethylene igomba kuba idafite uburakari ubwo aribwo bwose (imbere no hejuru) hamwe nu byobo byimbitse.Gucisha make niba bitagabanya umubyimba kugeza munsi yumupaka, ni ntarengwa.
Kugaragaza neza uburebure bwurukuta rwumuringa ukoresheje uburebure bwa ultrasonic gauge Calibrated calipers mugice cyo gutema mugihe impanda.
Diameter yo hanze yigituba ikoresheje ibyuma byapimwe (Sykrvmtr) hamwe no kumashami byapimwe kandi impuzandengo iravugwa
