Igishashara gikoreshwa mbere nkigishishwa hamwe na wino, birangwa no gukoresha byoroshye.Nyuma yo kubaka igifuniko, kubera guhindagurika kwa solvent, ibishashara mumvura igwa, bigakora kristu nziza, bikareremba hejuru ya firime ya coating, bigira uruhare runini mugutezimbere imikorere ya firime.Noneho, usibye ibishashara bya polymer, ibishashara bisanzwe ntibikoreshwa cyane mubitambaro na wino.Ahubwo, ibishashara bya polymer nibikomokaho byakoreshejwe.Bashobora guha firime kurwanya amazi meza, ubushuhe nubushyuhe, kurwanya ibishushanyo, kuzimangana, kurwanya ububi, no kumva neza ukuboko.Kurwanya kwabo kwinshi birenze ubushobozi bwo kuzimangana.Igishashara cya polipropileneni uburemere buke bwa polypropilene homopolymer cyangwa copolymer ikoreshwa cyane muri coatings.

Igikorwa cyaibishashara bya polipropilenebiterwa nimpamvu zikurikira: ubwoko butandukanye nibisobanuro bya polypropilene, ubwiza bwibice byarangije kubaho hamwe nubushobozi bwo kwimukira hejuru ya firime, hamwe nibigize igifuniko, imiterere ya substrate yubatswe, kubaka no kuyishyira mubikorwa buryo, n'ibindi. Ibikurikira bisobanura imikorere yacyo:
1. Kurimbuka.
Ibishashara bitandukanye bigira ingaruka zitandukanye kumurabyo wa firime: kuva kuzimangana gukabije kugeza kwiyongera kwinshi no gutanga urumuri rutandukanye nimirongo yinyundo.Umva: inyongeramusaruro zituma ibishashara bigira ibyiyumvo byiza, bidashobora kugerwaho nabandi bakozi bahuza.
2. Kwambara ukurwanya.
Kimwe mu bintu byanonosora anti friction hamwe na anti scratch ni ukugabanya coeffisiyoneri yo guterana hejuru yubuso, kuburyo mugihe ikintu gihuye nubuso bwacyo, icyerekezo cyo kunyerera kiba kinini kuruta kwikuramo.Ni muri urwo rwego, imikorere y’ibishashara bya polypropilene isa namavuta ya silicone.Itandukaniro nuko iyambere ibaho hejuru yububiko hejuru yuburyo bwiza butatanye.Gusa umubare muto urakenewe kugirango ugere kuburwanya.Igishashara cya polypropilene, cyongewe ku gipfukisho, kirashobora kugabanya cyane imyifatire yo guswera bitewe no guterana amagambo, kandi bikagumana igihe kirekire cy’urumuri ruto, akenshi rukenerwa mu kubishyira mu bikorwa.Kurugero, muri alkyd varnish, mugihe igipimo cyibishashara cya polypropilene ari 1.5%, agaciro ko kurwanya anti-firime karikuba kabiri, kandi iyo dosiye ari 3%, agaciro ko kurwanya kwambara kiyongera inshuro 5.Iyo ibintu byuma bihuye nibicuruzwa bisize, rimwe na rimwe bisiga ibimenyetso byirabura kuri firime.Ongeramo ibishashara bya polypropilene muri firime birashobora kugabanya iyi myumvire cyangwa gutuma ibimenyetso byoroshye guhanagura.Ibishashara bya Micro bifashishwa mugucapa wino kugirango bitezimbere cyane kwambara kwino.

3. Kurwanya gukomera.
Bimwe mubikorwa, nkibiti cyangwa zahabu byerekana ibintu, akenshi bigomba guhunikwa mugihe gito nyuma yo gutwikira.Iterambere rya tekinoroji yo gucapa risaba kandi wino kugirango wirinde kwanduza ibintu byacapwe.Igishashara cya polyethylene kirashobora gukumira gufatira hamwe n umwanda uterwa no guhuriza hamwe umusaruro cyangwa ibikoresho byo gucapa.
4. Kurwanya ubutayu, anti sagging na thixotropy.
Umwanya wibyuma.Ibishashara bya polyethylene bikwirakwijwe mumashanyarazi ya aromatiya na alifatique birashobora kongera imvura igwa yimyenda hamwe na wino.Irerekana kandi impamyabumenyi zitandukanye za thixotropy, kurwanya kugabanuka no guhagarara kwibyuma.
Igishashara cya polyethylene kirashobora kongerwaho kuri coat na wino muburyo bwinshi
.Ifu ya Micro nuburyo bukoreshwa cyane.Ibirango bitandukanye byifu y ibishashara birakwiriye gutwikirwa hamwe na wino yubwoko butandukanye nibisabwa.Bashobora gutoranywa ukurikije ibipimo ngororamubiri nibikorwa bya shimi hamwe nubunini bwikwirakwizwa ryibishashara.Imiterere yumubiri nubumashini bivuga cyane cyane kumiterere yibishashara ubwabyo, nkimiterere yimiti, uburemere bwa molekile, aho gushonga, kwinjira, agaciro ka aside, nibindi. Ingano yibice bivuga diameter yibice no kuyikwirakwiza, imiterere yibice hamwe nubuso bwa micron.
2) Amavuta yo kwisiga no gutatanya nuburyo bwo gukwirakwiza ibishashara mumazi, kandi ubunini bwibice buri munsi ya 1m.Munsi ya 200 nm, mubisanzwe biragaragara cyangwa bisobanutse.Ingano yingingo iri munsi ya 1m yitwa dispersion cyangwa itandukaniro ritandukanye.Gukwirakwiza amazi bituma gukoresha ibishashara bya polyethylene muri acrylate yo mu mazi hamwe na polyurethane hamwe na wino byoroshye cyane.
Qingdao Sainuo Chemical Co., Ltd.Turi gukora ibishashara bya PE, ibishashara bya PP, ibishashara bya OPE, ibishashara bya EVA, PEMA, EBS, Zinc / Kalisiyumu Stearate….Ibicuruzwa byacu byatsinze REACH, ROHS, PAHS, FDA ikizamini.
Sainuo humura ibishashara, ikaze iperereza ryawe!
