Uburyo nihame ryo kuzimangana muri UV hamwe na PU

Kurimbuka ni ugukoresha uburyo bumwe bwo kugabanya ububengerane bwubuso.

1. ihame ryo kuzimira

Ufatanije nuburyo bwimiterere yubuso bwa firime nibintu bigira ingaruka kumurabyo, abantu bemeza ko kuzimangana ari ugukoresha uburyo butandukanye kugirango usenye neza firime, wongere mikorobe yubuso bwa firime, kandi bigabanye kwerekana isura ya firime. kumurika.Irashobora kwigabanyamo ibice byo kuzimangana no kuzimangana.Ihame ryo guhuza umubiri ni: ongeraho ibikoresho byo guhuza kugirango ubuso bwa coating butaringaniye murwego rwo gukora firime, kongera urumuri rwumucyo no kugabanya gutekereza.Kurimbuka kwimiti ni ukubona ububengerane buke mugutangiza ibintu bimwe na bimwe bikurura urumuri cyangwa amatsinda nka polypropilene yometse kubintu muri UV.

2. uburyo bwo kuzimangana

Umukozi wo guhuza, mubikorwa bya UV byo gutwikira uyumunsi, abantu muri rusange bakoresha uburyo bwo kongeramo ibikoresho.Hariho ibyiciro bikurikira:

(1) Isabune y'icyuma

Isabune y'icyuma ni ubwoko bwimikorere ikunze gukoreshwa nabantu bo hambere.Nubusanzwe ibyuma bimwe na bimwe byuma, nka aluminium stearate, zinc stearate, calcium stearate, magnesium stearate nibindi.Aluminium stearate niyo ikoreshwa cyane.Ihame ryo kuzimangana ryisabune yicyuma rishingiye ku kudahuza kwayo.Ihagarikwa mugipfundikizo hamwe nibice byiza cyane, bigabanywa hejuru yikigina iyo firime ikozwe, bikavamo ubukana bwa micro hejuru yubuso kandi bikagabanya urumuri rwumucyo hejuru yigitereko kugirango bigerweho intego yo kuzimira.

(2) Igishashara

Igishashara nikintu cyambere kandi gikoreshwa cyane muguhuza, kikaba ari icyuma gihagarikwa kama.Nyuma yo kubaka igifuniko, hamwe no guhindagurika kwumuti, ibishashara muri firime ya coating biratandukana kandi bigahagarikwa hejuru ya firime ya coating hamwe na kristu nziza, bigakora urwego rwubuso butatanye kandi rukagira uruhare mukuzimangana.Nkumuti uhuza, ibishashara biroroshye gukoresha, kandi birashobora guha firime ibyiyumvo byiza, kurwanya amazi, ubushuhe nubushyuhe, hamwe no kurwanya ikizinga.Nyamara, nyuma y’ibishashara bimaze gushingwa hejuru ya firime, bizanarinda guhindagurika kwa solvent no kwinjira muri ogisijeni, bigira ingaruka ku gukama no kwisubiramo kwa firime.Iterambere ryiterambere mugihe kizaza nuguhuza ibishashara bya polymer na silika kugirango ubone ingaruka nziza zo kuzimira.

(3) Amande y'imikorere

Ibara ryumubiri, nka diatomite, kaolin na silika ya fumasi, ni ihazabu yimikorere ikoreshwa cyane nkibikoresho byo guhuza.Nibintu bidasanzwe byuzuza ibikoresho.Iyo firime yumye, utuntu duto duto duto tuzakora micye igaragara hejuru ya firime kugirango igabanye urumuri kandi ibone Mat.Ingaruka yo guhuza ubwoko bwubwoko bwo guhuza ibuzwa nimpamvu nyinshi.Dufashe silika nkurugero, mugihe ikoreshejwe nkibikoresho byo guhuza, ingaruka zayo zo guhuza bizagerwaho nibintu nkubunini bwa pore, impuzandengo yikigereranyo hamwe nubunini bwagabanijwe, ubunini bwa firime yumye kandi niba ubuso bwaravuwe.Ubushakashatsi bwerekana ko imikorere yo kuzimangana ya dioxyde ya silika ifite ubunini bunini bwa pore, ingano yingingo imwe ikwirakwizwa hamwe nubunini bujyanye nubunini bwa firime yumye nibyiza.

Usibye ubwoko butatu bwavuzwe haruguru bukoreshwa muburyo bwo guhuza ibintu, amavuta yumye, nkamavuta ya tung, arashobora no gukoreshwa nkibikoresho byo guhuza imyenda ya UV.Ikoresha cyane cyane reaction yo hejuru ya conjugated double bond ya mavuta ya tung kugirango hasi ya firime igire okiside itandukanye kandi yihuta ihuza, kuburyo ubuso bwa firime butaringaniye kugirango bigerweho.
