Dehwe harisi fashoni chete, asi zvakare mhedzisiro yemaitiro akanaka emakemikari anozivikanwa sekutsvukisa ganda. Munyaya yemakemikari eganda, maitiro makuru anoonekwa -kucheneswa kweganda Ngatitangei rwendo runonakidza rwekutsvaga zvakavanzika zvekuchengetedza ganda, nzira inokosha mukugadzira dehwe, uye kuongorora nyika inoshamisa yemakemikari edehwe.
1. Sainzi yekutsvukisa dehwe: Kutsvukisa dehwe inzira yekushandura dehwe remhuka dzisina kubikwa kuita zvinhu zvakasimba uye zvinochinjika. Maitiro aya anosanganisira maitiro akasiyana-siyana emakemikari anosimbisa collagen fibers iri mudehwe uye anoridzivirira kuti risaora. Mishonga yemakemikari inonzi retanning agents inoita basa rakakosha mutsvukisa dehwe.
2. Tsvaga kudzorerwa kwehujaya nemishonga yekudzivirira kutonhora: Mishonga inochenesesa ganda zvinhu zvakakosha zvinoshandiswa pakugadzira ganda. Mishonga iyi inokosha pakuita kuti ganda rive rakapfava, rinochinjika uye rirambe rakapfava. Inovandudzawo huremu hwaro uye simba rayo.
3. Kune mhando dzakawanda dzemishonga yekudzivirira kutonhora: Zvinoumba ganda retanning zvinouya nenzira dzakasiyana, imwe neimwe iine basa rayo. Zvizadza, zvakaita se kaolin, zvinoshandiswa kuzadza nzvimbo dziri mukati meganda, zvichiita kuti zvinhu zvive zvakapfava uye zvine magadzirirwo. Ma resin, akadai se acrylics, anobatsira kubatanidza ma fibers pamwe chete kuti awedzere simba. Mafuta, akadai semafuta ekugadzira neakasikwa, anozora ganda uye anowedzera kuchinjika kwaro. Pamusoro pezvo, mishonga yakagadzirwa ne sarufa inoshandiswa kubatsira polymerization yemakemikari e retanning, nokudaro zvichiwedzera kugara kwenguva refu.
4. Kufunga nezvezvakatipoteredza: Mumakore achangopfuura, indasitiri yeganda yakachinja pfungwa dzayo kuenda kune maitiro ekugadzira anochengetedza nharaunda uye asingakuvadzi nharaunda. Nekufambira mberi muhunyanzvi hwematehwe, zvinhu zvinochenesa nharaunda zvakaita sezvirimwa zvakatorwa uye biomimetic compounds zvave kufarirwa nekuda kwekushomeka kwazvo kwekukanganisa nharaunda. Zvinhu izvi zvinoderedza kuburitswa kwezvinhu zvinokuvadza munharaunda, zvichiita kuti kusvibisa ganda kuve tsika inogara kwenguva refu.
5. Tevedzerai mitemo yemhando yepamusoro: Zvigadzirwa zveganda zvinoongororwa zvakanaka uye zvinosangana nemitemo yepasi rose. Kushandisa mishonga yekuchenesesa ganda nokungwarira kunoita kuti chigadzirwa chekupedzisira chisvike pane zvinodiwa zvakaita sekuenderana kweruvara, kupfava uye kuramba kukwenya kana kubvaruka. Matekiniki epamusoro ekuongorora, anosanganisira kuongorora electron microscopy uye spectroscopic analysis, anobatsira kuona kuti izvi zvine mhando yepamusoro. Mukupedzisa: Nyika yekuchenesesa ganda uye kuchenesesa ganda musanganiswa unonakidza weunyanzvi hwesainzi, hunyanzvi uye ruzivo rwezvakatipoteredza.
Sezvo indasitiri yematehwe ichiramba ichichinja, kufambira mberi mune tekinoroji uye makemikari ari kuvimbisa kupa zvigadzirwa zvematehwe zvemhando yepamusoro uye zvinogara kwenguva refu. Kunzwisisa kuomarara kwekuchengetedza ganda uye maitiro anoenderana naro emakemikari hakuzongowedzera chete kukoshesa kwedu zvigadzirwa zvematehwe asiwo kunoratidza kugona kukuru kweindasitiri yemakemikari ematehwe. Nekuongorora nyika yemakemikari ematehwe, tinoburitsa zvakavanzika zvekugadzira matehwe akanaka anosanganisira kugara kwenguva refu, kushanduka-shanduka uye runako, uku tichifambirana nezvinodiwa zviri kukura zvekuchengetedza ganda.
