Polypropilene idakozwe na polyester

Imyenda idoda ntabwo ari imyenda iboshywe, ahubwo igizwe na fibre yerekanwe cyangwa idahwitse, bityo nanone yitwa imyenda idoda. Bitewe nibikoresho bitandukanye hamwe nuburyo bwo kubyaza umusaruro, imyenda idoda irashobora kugabanywamo ubwoko bwinshi, nkapolyester idoda, polypropilene imyenda idoda, nibindi.

Abakiriya bakunze kubaza itandukaniro riri hagati yimyenda ya polyester idoda, polipropilene idoda idoda, fibre polypropilene, na polyester mugihe bagisha inama ibicuruzwa bidoda. Hasi nurutonde rwibyo batandukaniyeho.

SHAKA imyenda idoda

PET spunbond filament idoda idoda ni ubwoko bwimyenda idasubiza amazi idoda, kandi imikorere yayo yo kurwanya amazi iratandukanye bitewe nuburemere bwimyenda. Ibinini binini kandi binini, niko imikorere irwanya amazi. Niba hari ibitonyanga byamazi hejuru yimyenda idoda, ibitonyanga byamazi bizahita bitembera hejuru.

Polyester idoda idoda irwanya ubushyuhe bwinshi. Bitewe no gushonga kwa polyester iba hafi 260 ° C, irashobora kugumana ituze ryimiterere yinyuma yimyenda idoda mubidukikije bisaba kurwanya ubushyuhe. Yakoreshejwe cyane mugucapura ubushyuhe, kuyungurura amavuta yohereza, hamwe nibikoresho bimwe bisaba kwihanganira ubushyuhe bwinshi.

PET spunbond imyenda idodani ubwoko bwa filament idoda imyenda ya kabiri nyuma ya nylon spunbond idoda. Imbaraga zayo nziza, uburyo bwiza bwo guhumeka ikirere, kurwanya ubukana, kurwanya amarira hamwe no kurwanya gusaza byakoreshejwe mubice bitandukanye nabantu benshi kandi benshi.

PET spunbond imyenda idoda nayo ifite umutungo wihariye udasanzwe: kurwanya imirasire ya gamma. Nukuvuga ko, iyo ikoreshejwe mubicuruzwa byubuvuzi, imirasire ya gamma irashobora gukoreshwa muburyo butaziguye kugirango yanduze itangiza ibyangiritse byumubiri ndetse nuburinganire bwimiterere, ibyo bikaba umutungo wumubiri polipropilene (PP) spunbond idoda idoda idafite.

Polipropilene idoda

Umwenda udoda udoda ubudodo werekana filime ihoraho ikorwa no gusohora no kurambura polymers, ishyirwa kurubuga. Urubuga noneho rwihuza, rushyizwe hamwe, rushyizwe mumiti cyangwa rukoreshwa muburyo bwa mashini kugirango uhindure urubuga imyenda idoda. Ikoreshwa mubicuruzwa by isuku bikoreshwa, nkimyenda yisuku, amakanzu yo kubaga, ingofero, masike, ibitanda, ibitambaro byimpuzu, nibindi bikoreshwa mubitabo bya buri munsi kubisanzwe.

Polypropilene idakozwe na polyester

PP ni ibikoresho fatizo bya polypropilene, aribyo fibre polypropilene, ikaba ari imyenda idahwitse; PET ni igikoresho gishya cya polyester kibisi, aricyo fibre polyester, nta nyongeramusaruro mubikorwa byose byakozwe. Nibicuruzwa byiza cyane byangiza ibidukikije kandi nibyimyenda idoze.

Itandukaniro hagati ya polypropilene na fibre polyester

1 principle Ihame ry'umusaruro

Amahame yumusaruro wa polypropilene na polyester fibre iratandukanye. Polypropilene itegurwa no gushyushya monomers ya propylene ku bushyuhe bwo hejuru no kuyongerera umusemburo wa polymerisiyumu, mu gihe fibre ya polyester itunganyirizwa mu bikoresho bya fibre hongerwamo selile ya etherification ya selile na solide kuri resin ya polyester.

2 ibiranga umutungo

1. Kubireba imiterere yumubiri:

Polypropilene iroroshye kandi ifite imbaraga za fibre nyinshi, ariko kwihanganira kwambara no kurwanya ubushyuhe bukabije ni bibi. Fibre ya polyester ifite imbaraga zingana kandi ziramba, hamwe nubushyuhe hamwe nubushakashatsi bwimiti, bigatuma ubuzima bumara igihe kirekire.

2. Kubireba imiterere yimiti:

Polypropilene ifite imiterere ihamye yimiti, ntishobora kwangirika byoroshye na acide, alkalis, nibindi, kandi ntabwo irimo ibintu byuburozi kandi byangiza. Fibre polyester irimo imiterere yimpeta ya benzene kandi ifite urwego runaka rwo kurwanya ruswa.

3. Kubijyanye no kubungabunga ibidukikije:

Polypropilene ni ibikoresho bya termoplastique bitoroshye kwangirika kandi byangiza ibidukikije. Fibre polyester irashobora kwangizwa na mikorobe kandi ntizitera umwanda ibidukikije.

Itandukaniro hagati ya PP idoda idoda naSHAKA imyenda idoda

1. PP ibikoresho fatizo bihendutse, mugihe PET ibikoresho fatizo bihenze. Imyanda ya PP irashobora gukoreshwa mu itanura, mugihe imyanda ya PET idashobora gutunganywa, bityo igiciro cya PP kiri hasi gato.

2. PP ifite ubushyuhe bwo hejuru bwa dogere 200, mugihe PET ifite ubushyuhe bwa dogere 290. PET irwanya ubushyuhe bwinshi kuruta PP.

3. Icapiro ryimyenda idoda, ingaruka zo kohereza ubushyuhe, ubugari bumwe PP igabanuka cyane, PET igabanuka gake, ifite ingaruka nziza, PET ibika byinshi kandi isesagura bike.

4. Garama 65 za PET zingana na garama 80 za PP mubijyanye no guhagarika umutima, guhagarika umutima, hamwe nubushobozi bwo gutwara imitwaro.

5. Urebye kubidukikije, PP ivanze n imyanda ya PP itunganijwe neza, kandi chip zose za PET ni shyashya. PET yangiza ibidukikije nisuku kuruta PP.
