Polypropilene ni iki?

1. bitandukanye

Ubwoko bwa fibre polypropilene harimo filament (harimo na filament idakozwe neza na filament nini cyane), fibre staple, mane fibre, fibre fibre fibre, fibre fibre, fibre profile, fibre zitandukanye hamwe nimyenda idoda.Ikoreshwa cyane cyane mugukora amatapi (harimo imyenda ya tapi na suede), imyenda yo gushushanya, imyenda yo mu nzu, imigozi itandukanye, imirongo, inshundura zo kuroba, felte ikurura amavuta, kubaka ibikoresho byubaka, ibikoresho byo gupakira hamwe nigitambara cyo mu nganda, nk'imyenda ya filteri na igitambaro.Byongeye kandi, ikoreshwa cyane mu myambaro.Irashobora kuvangwa na fibre zitandukanye kugirango ikore ubwoko butandukanye bwimyenda ivanze.Nyuma yo kuboha, irashobora gukorwa mumashati, imyenda yo hanze, imyenda ya siporo, amasogisi, nibindi. Igitambara gikozwe muri fibre polypropilene cyoroshye ni cyoroshye, gishyushye kandi cyoroshye.

2. Imiterere yimiti

Izina ry'ubumenyi rya fibre polypropilene ni uko ishonga hafi yumuriro, ikongoka, igatwikwa buhoro buhoro kure yumuriro kandi igatanga umwotsi wirabura.Impera yo hejuru yumuriro ni umuhondo naho hepfo yo hepfo ni ubururu, itanga impumuro ya peteroli.Nyuma yo gutwika, ivu rirakomeye, rizengurutse kandi rifite ibara ry'umuhondo ibice byijimye, byoroshye iyo bihinduwe n'intoki.

3. Imiterere yumubiri

Indege ndende ya morphologiya polypropilene fibre iringaniye kandi yoroshye, kandi igice cyambukiranya ni uruziga.

Inyungu nini ya fibre polypropilene yubucucike nuburyo bworoshye bwurumuri, ubwinshi bwayo ni 0,91g / cm3 gusa, aribwo bwoko bworoshye bworoshye bwimisemburo isanzwe ya chimique, bityo fibre imwe ya polypropilene irashobora kubona ahantu hanini cyane kuruta izindi fibre.

Tensile polypropylene fibre ifite imbaraga nyinshi, kurambura kwinshi, modulus yambere yambere hamwe na elastique nziza.Kubwibyo, polypropilene fibre irwanya kwambara neza.Byongeye kandi, imbaraga zitose za polypropilene zingana cyane nimbaraga zumye, kubwibyo rero nibikoresho byiza byo gukora inshundura ninsinga.

Kandi ifite hygroscopique yoroheje kandi irangi, kugumana ubushyuhe bwiza;Hafi yo kutagira amazi, ariko ubushobozi bukomeye bwo kwinjiza, kugaragara neza no kubira ibyuya;Fibre ya polypropilene ifite ubwinshi bw’amazi, hafi yo kutagira amazi, kandi nubushuhe bugaruka mubihe rusange byikirere biri hafi ya zeru.Ariko, irashobora gukurura imyuka y'amazi ikoresheje capillaries mu mwenda, ariko ntigira ingaruka zo kwinjiza.Fibre ya polypropilene ifite irangi rike hamwe na chromatografiya ituzuye, ariko irashobora gukorwa nuburyo bwo gusiga amabara.

Polypropilene irwanya aside na alkali ifite imiti irwanya ruswa.Usibye aside nitricike yibanze hamwe na soda ya caustic yibanze, polypropilene ifite imbaraga zo kurwanya aside na alkali, bityo rero irakwiriye gukoreshwa nkibikoresho byo kuyungurura no gupakira.

Umuvuduko mwinshi, nibindi.Ariko, imikorere yo kurwanya gusaza irashobora kunozwa wongeyeho imiti igabanya ubukana mugihe cyo kuzunguruka.Byongeye kandi, polypropilene ifite amashanyarazi meza, ariko biroroshye kubyara amashanyarazi ahamye mugihe cyo kuyatunganya.Polypropilene ifite ubushyuhe buke hamwe nubushyuhe bwiza.

Imbaraga zimbaraga nyinshi za polypropilene elastike yintambara ni iya kabiri nyuma ya nylon, ariko igiciro cyayo ni 1/3 gusa cya nylon.Imyenda yakozwe ifite ubunini buhamye, irwanya abrasion nziza na elastique, hamwe n’imiti ihamye.Nyamara, bitewe nubushyuhe buke bwumuriro, kurwanya insolisiyo no gusaza byoroshye no kwangirika gukabije, imiti igabanya ubukana yongerwa kuri polypropilene.

4. Gukoresha

Imikoreshereze yabaturage: Irashobora kuzunguruka neza cyangwa ikavangwa nubwoya, ipamba cyangwa viscose kugirango ikore ibikoresho byose byimyenda.Irashobora gukoreshwa mu kuboha ubwoko bwose bwimyenda yububoshyi nkamasogisi, gants, imyenda yububoshyi, ipantaro yububoshyi, imyenda yisahani, igitambaro cyinzitiramubu, igitanda, ibintu bishyushye, impuzu zitose, nibindi.

Inganda zikoreshwa mu nganda: itapi, inshundura zo kuroba, canvas, amacupa, gushimangira beto, imyenda yinganda, imyenda idoda, nibindi nkibitambaro, imyenda yo kuyungurura inganda, imigozi, inshundura zuburobyi, kubaka ibikoresho byubaka, ibiringiti bikurura amavuta nigitambara cyo gushushanya, nibindi byongeyeho, fibre ya polypropilene irashobora gukoreshwa nkibikoresho byo gupakira. 

5. Imiterere

Fibre ya polypropilene ntabwo irimo amatsinda yimiti ashobora guhuza amarangi mumiterere ya macromolecular, kuburyo bigoye kuyisiga.Mubisanzwe, gutegura pigment hamwe na polypropilene polymer bivangwa kimwe mumashanyarazi ya screw hakoreshejwe uburyo bwo gusiga amabara, kandi fibre yamabara yabonetse mukuzunguruka ifite umuvuduko mwinshi.Ubundi buryo ni copolymerisation cyangwa graft copolymerisation hamwe na acide acrylic, acrylonitrile, vinyl pyridine, nibindi, kuburyo amatsinda ya polar ashobora guhuzwa namabara yinjizwa muri polymer macromolecules, hanyuma agasiga irangi muburyo busanzwe.Mubikorwa byo gukora fibre polypropilene, akenshi birakenewe kongeramo inyongeramusaruro zinyuranye kugirango tunoze irangi, irwanya urumuri hamwe n’umuriro.
