Intangiriro n'Ikoreshwa ry'Ikoranabuhanga ryo Guhindura Ingufu Zitagira Halogen ku Bikoresho bya Polypropylene (PP)

Bitewe n’amabwiriza akomeye yo kubungabunga ibidukikije no kongera ubumenyi ku mutekano w’abaguzi, ikoranabuhanga rya polypropylene idakoresha umuriro idafite halogen ryabaye amahitamo y’ingenzi mu guhuza imikorere y’ibikoresho n’umutekano no kurengera ibidukikije. Ibintu bisanzwe bikoresha umuriro bikoresha halogen bitanga imyuka y’uburozi n’iyangiza mu gihe cyo gutwika, mu gihe ibintu bikoresha umuriro bidafite halogen V0, bifite imiterere yabyo irinda ibidukikije n’ubushobozi bwo kwirinda umuriro, bigira uruhare runini mu nganda zitandukanye.

01 Ikoranabuhanga: Ihame ry'imikorere n'ubwoko bw'icyuma kidakoresha umuriro cya V0 kidakoresha halogen

Ikoranabuhanga ry'ingenzi ry'ibikoresho bigabanya umuriro bya V0 bidafite halogen riri mu buryo bwabyo bwihariye bwo gukumira umuriro. Iyo bihuye n'ubushyuhe bwinshi, ibyo bikoresho bigabanya umuriro bikora urwego rumwe kandi rwuzuye rw'ifuro ry'amakara ku buso bw'ibikoresho. Uru rwego rw'ifuro rurinda ubushyuhe na ogisijeni neza, kandi rubuza umwotsi gukora, bityo rukaba rufite amanota ya V-0 yo gukumira umuriro.

Ibintu bigabanya umuriro biva kuri azote mu mubiri ni byo bikunze gukoreshwa cyane: gukoresha fosifore na azote nk'ingenziirinda umuriroibintu, kongeramo hafi 24%-26% kuri polypropylene birahagije kugira ngo hagerwe ku gipimo cya UL94 V-0 ku gipimo cya 1.6mm. Ubwo bwoko bw'ikintu kidakoresha umuriro kirangwa no kutagira umwotsi mwinshi, uburozi buke, no kutabangamira ibidukikije, bikurikije amabwiriza ya EU RoHS ku bidukikije n'amabwiriza agenga ibidukikije yo mu ngo.

02 Ahantu hakoreshwa: Kuva ku bikoresho by'ikoranabuhanga n'amashanyarazi kugeza ku bice by'imodoka

Ibikoresho bya PP bitagira halogen V0 bigabanya umuriro byakoreshejwe cyane mu nganda nyinshi, hamwe n'ibikorwa by'ingenzi birimo:
Mu rwego rw'ibikoresho by'ikoranabuhanga n'amashanyarazi, izi mashini zigabanya umuriro zikoreshwa cyane mu gukoresha ibikoresho bitandukanye byo mu nzu n'ibindi bikoresho, nk'amazu acukurwamo umuceri, amazu acukurwamo amasafuriya akoresha amashanyarazi, amazu acukurwamo amazi, hamwe n'aho firigo n'imashini imesa.
Mu nganda z'imodoka, ibikoresho bigabanya umuriro bya V0 bidafite halogen bikoreshwa mu bice by'ikoranabuhanga rikonjesha umwuka w'imodoka, mu byuma bikonjesha hagati, n'ibindi bice.
Mu rwego rw'ibikoresho by'ubwubatsi, PP irinda umuriro idafite halogen ikoreshwa mu bikoresho nk'impapuro n'ibibaho.

03 Ingingo z'ububabare: Guhuza, Guhagarara neza k'ubushyuhe, n'imbogamizi zo gutunganya

Nubwo hari ibyiza byinshi bya PP itagira halogen V0 irinda umuriro, haracyari imbogamizi nyinshi mu mikoreshereze y’ibikoresho:

Ikibazo cy'ingenzi ni ukutumvikana nabiGufataammonium polyphosphate (APP)Urugero, ikoreshwa cyane mu gucukura umuriro utagira halogen, polarity yayo ikomeye ituma idahura neza na polypropylene itari polar, ibyo bikaba byagira ingaruka ku miterere y’ibikoresho iyo byongewemo byinshi.

Kudakomeza ubushyuhe bihagije ni ikindi kibazo gikomeye. APP ni polymer y'umweru ifite ifu idakomeye kandi idashobora kwihanganira ubushyuhe. Mu gihe cyo gutunganya ubushyuhe bwinshi, irangirika, ihinduka ibintu nka ammonium phosphate, aside metaphosphoric, ammonia, n'umwuka w'amazi. Ibi bintu byo kubora, nka aside metaphosphoric, bisigaye muri resin bishobora kugwa mu gihe cyo gushushanya, bigafata ku rukuta rw'ibumba cyangwa ku ruzitiro, bigagira ingaruka zikomeye ku miterere y'ibicuruzwa no ku mikorere myiza yabyo.

Gukurura no kwimuka k'ubushuhe nabyo ni ibibazo bikomeye. APP ifite ubushobozi bwo gukurura amazi mu kirere, yorohereza guhumeka amazi ava mu kirere, hanyuma akagenda ajya ku buso bw'ibikoresho, bigatera igihombo. Ibi ntibigira ingaruka gusa ku kuramba kw'ibintu bigabanya umuriro ahubwo bishobora no gutera inenge ku buso bw'ibicuruzwa.

Kongeraho byinshiIkindi kandi ni ikibazo gikunze guhura na PP itagira umuriro idashobora gutwika. Ugereranyije n'ibikoresho bisanzwe bigabanya umuriro bidafite halogen, sisitemu zitagira halogen zikenera kongeramo ingano nyinshi kugira ngo zigere ku gipimo cya V-0, ibi bikaba bitera imbogamizi ku miterere y'ibikoresho ndetse no kugenzura ikiguzi.

04 Ibisubizo n'amabwiriza y'iterambere ry'ejo hazaza

Mu guhangana n'ibibazo bya tekiniki mu gukoresha PP idakoresha halogen V0 irinda umuriro, inganda zakoze ibisubizo byinshi byiza:
-Gutunganya no kunoza uburyo bwo gukora isuku ni uburyo bwiza bwo kunoza imikoranire.
-Gutunganya uburyo bwo kugenzura ibikorwa nabyo ni ingenzi cyane.
-Guteza imbere uburyo bushya bwo gukumira inkongi z'umuriro ni cyo gisubizo cy'ibanze.
