Igitambara

Amateka yiterambere
Imyaka irenga 2000 irashize
Mu Bushinwa bwa kera, kole yo gutwikira yari isanzwe ikoreshwa hejuru y'imyenda. Muri kiriya gihe, wasangaga ahanini ibintu bisanzwe nka lacquer hamwe namavuta ya tung, byakoreshwaga cyane mugukora imyenda idakoresha amazi.
bigezweho
Ubwoko butandukanye bwa sintetike ya polymer itwikiriye hamwe nibikorwa byiza byagaragaye. Igicuruzwa cyumwimerere cyari gifite inenge yo kutagira amazi gusa ariko nticyemererwa nubushuhe. Imyenda isize yumvaga yuzuye kandi ishyushye iyo ikoreshejwe, kandi ihumure ryayo ryari ribi.
Kuva mu myaka ya za 70
Abashakashatsi bakoze urukurikirane rw'ibikoresho bitarimo amazi ndetse n'ubushuhe bworoshye bwo gutwikisha imyenda bahindura imiterere ya shimi yo gufatira hamwe no guhindura uburyo bwo gutunganya.
Mu myaka yashize
Ibikoresho bifata neza hamwe nibikoresho bifatanye nabyo byateye imbere cyane

Gutondekanya ukurikije imiterere yimiti
1. Polyacrylate (PA):
Bizwi kandi nka AC adhesive coating, ni ibisanzwe kandi bisanzwe muri iki gihe. Nyuma yo gutwikira, irashobora kongera ukuboko kumva, kutagira umuyaga hamwe na sag.
PA yera ya kole yera, ni ukuvuga, gutwikira igipande cya resili yera ya acrylic yera hejuru yigitambara, irashobora kongera igipfukisho cyigitambara, ikagikora neza, kandi bigatuma ibara ryigitambara rirushaho kumurika.
PA ifu ya kashe ya feza, ni ukuvuga, igipande cya silver yera cyera yometse hejuru yigitambara, kuburyo umwenda ufite umurimo wo gukingira urumuri nimirasire. Ubusanzwe ikoreshwa kumyenda, amahema n'imyambaro.
2. Polyurethane (PU):
Nyuma yo gutwikira, umwenda wunvikana kandi woroshye, kandi hejuru ifite firime.
Pu yera ya kole yera, ni ukuvuga, igipande cya poliurethane yera isize hejuru yigitambaro, kandi imikorere yacyo ahanini irasa nkiya PA yera, ariko igipfundikizo cya Pu cyera gifite ibyiyumvo byuzuye, byoroshye. no kwihuta cyane.
Pu silver glue coating ifite ibikorwa byibanze nkibikoresho bya PA silver. Ariko, Pu silver yuzuyeho imyenda ifite elastique nziza kandi yihuta. Ku mahema nandi myenda isaba umuvuduko mwinshi wamazi, Pu silver yometseho iruta imyenda ya PA ifunze.
3.Porivinyl chloride (PVC):
Ikozwe mu mwenda wa fibre fibre, umwenda w ipamba wikirahure hamwe nigitambara cya fibre fibre kandi ushyizwe mubikorwa bidasanzwe. Ibikorwa byingenzi byingenzi biranga ni: amazi adashobora gukoreshwa n’amazi, kwirinda umuriro, ibimenyetso byoroheje, ibimenyetso bikonje hamwe na ruswa (byitwa "imyenda itatu yerekana" n "" imyenda itanu yerekana "); Kurwanya gusaza; Kurinda UV; Biroroshye koza; Kurwanya ubushyuhe bwinshi (180 ℃) hamwe no kubika neza ubushyuhe.
4. Silicone:
Silicone ihanitse cyane, izwi kandi nk'impapuro. Ipamba ntoya irakwiriye cyane gukora imyenda. Irumva yuzuye, yoroheje kandi yoroheje, hamwe no kwihangana gukomeye no kurwanya inkeke. Ku myenda yijimye, ifite elastique nziza kandi yihuta.
5. Rubber ya sintetike (nka neoprene).
Mubyongeyeho, hariho polytetrafluoroethylene, polyamide, polyester, polyethylene, polypropilene na proteyine.
Kugeza ubu, polyacrylates na polyurethanes zikoreshwa cyane.
