Haisi yeganda chete chirevo chefashoni, ihwowo mhedzisiro yeakanaka kemikari process inozivikanwa sekuti tanning.Mundima yemaitiro emakemikari ematehwe, imwe nzira yakakosha inomira pachena -retanning Ngatitange rwendo runonakidza rwekutsvaga zvakavanzika zvekudzoreredza, chiitiko chakakosha mukugadzirwa kwematehwe, uye kuongorora nyika inoshamisa yemakemikari ematehwe.
1. Sainzi inokonzeresa kusukutwa kwematehwe: Kupisa matehwe inzira yekushandura matehwe emhuka mbishi kuva zvinhu zvinogara uye zvinochinjika.Kuita uku kunosanganisira nhevedzano yemakemikari anoita inodzikamisa collagen fibers mukati medehwe uye kudzivirira kuti isaora.Nyanzvi dzemakemikari dzinodanwa kuti retanning agents dzinoita basa rakakosha mukucheneswa.
2. Vhura rejuvenation neretanning agents: Zvinochenesa zvinhu zvakakosha zvinoshandiswa padanho rekuchenesa rekugadzirwa kwematehwe.Aya maajenti akakosha pakupa zvinhu zvinodiwa kune dehwe sekupfava, elasticity uye kukurumidza kwemavara.Ivo zvakare vanovandudza huwandu hwayo hwese uye simba.
3. Kune marudzi akawanda eretanning agents: Madhiri ekudzosa anouya nenzira dzakasiyana, imwe neimwe iine basa chairo.Mafirita, akadai se kaolin, anoshandiswa kuzadza nzvimbo dziri mukati meganda reganda, zvichipa zvinhu kutsvedzerera uye kugadzirwa.Resins, senge ma acrylics, anobatsira kubatanidza fiber pamwe chete kuti iwedzere simba.Mafuta, akadai semafuta ekugadzira uye echisikigo, anozora dehwe uye anowedzera kushanduka kwayo.Pamusoro pezvo, sulfur-based compounds inoshandiswa kufambisa polymerization yemakemikari ekudzoreredza, nekudaro kuwedzera kusimba.
4. Mafungiro ezvakatipoteredza: Mumakore achangopfuura, indasitiri yematehwe yakashandura kutarisa kwayo kune yakagadzikana uye eco-hushamwari yekugadzira maitiro.Nekufambira mberi mutekinoroji yematehwe, ecological tanning agents senge zvinomera zvidyarwa uye biomimetic komisheni zvakawana mukurumbira nekuda kwekudzikira kwavo nharaunda.Aya maajenti anoderedza kuburitswa kwezvinhu zvinokuvadza munzvimbo, zvichiita kuti kutsvuka kwematehwe kuve kwakasimba.
5. Omerera kuhutano hwemhando: Zvigadzirwa zvematehwe zvinoedzwa zvakasimba uye zvinosangana nemitemo yenyika.Kunyatso shandiswa kwezvekuchenura kunovimbisa kuti chigadzirwa chekupedzisira chinosangana nezvinodiwa sekuenderana kweruvara, kupfava uye kuramba kukwenya kana kubvarura.Maitiro ekuongorora epamberi, anosanganisira kupenengura electron microscopy uye spectroscopic ongororo, inobatsira kuona aya emhando paramita.mukupedzisa: Nyika yematehwe nekutsvairwa patsva musanganiswa unonakidza wesainzi, hunyanzvi uye kuziva kwezvakatipoteredza.
Sezvo indasitiri yematehwe iri kuramba ichishanduka, kufambira mberi mune tekinoroji uye kugadzirwa kwemakemikari kunovimbisa kupa zvemhando yepamusoro, zvigadzirwa zvematehwe zvinogara zviripo.Kunzwisisa kuomesesa kwekutsvuka nekuita kwazvinoita kemikari hakungowedzere kukoshesa kwedu zvinhu zvematehwe asiwo kunoratidza kugona kukuru kweindasitiri yemakemikari ematehwe.Nekunyura munyika yekemikari yematehwe, tinoburitsa zvakavanzika kuseri kwekugadzira matehwe akanaka anoratidza kusimba, kuita zvakasiyana-siyana uye runako, tichifambirana nekukura kuri kuda kuti zvirambe zviripo.
