Kushandiswa kweformic acid mumatehwe

Kushandiswa kweformic acid mudehwe

Leather iganda remhuka rine denatured rinowanikwa nekugadzirwa kwemuviri nemakemikari sekubvisa bvudzi nekutsvuka.Formic acid yakashandiswa mune zvakasiyana-siyana zvinongedzo senge kubviswa kwebvudzi, kutsvuka, kugadzirisa kwemavara uye pH kugadziridzwa mukugadzirisa matehwe. Basa chairo reformic acid mumatehwe ndeiyi inotevera:

1. Kubvisa bvudzi

Formic acid inogona kupfavisa fur, uye kukurudzira kuparara uye kubviswa kweprotein, iyo inobatsira mukuchenesa uye kunotevera kugadzirisa kweganda.

2. Kutsvuka

Mukugadzirwa kwematehwe.formic acid inogona kushandiswa sechinhu chisina kusimba chekubatsira mumiriri wematehwe kuti aite zvizere basa rayo, nokudaro achivandudza kuoma uye kupfava kweganda.

3. Kugadzika uye kudhaya

Panguva yekugadzika kwemavara uye kudhayiwa kwematehwe,formic acid inobatsira dhayi kupinda mukati meganda uye kuwedzera dhizaini, ichidzivirira dehwe kubva mukukuvadzwa kunokonzerwa nemamorekuru edhayi. Kushandisa zvine musoro kweformic acid inogona kuvandudza kuumbwa kweganda uye kuita kuti pamusoro peganda riwedzere kutsetseka uye kupenya.

4. Gadzirisa pH

Formic acid inogona kushandiswa kudzora pH panguva yekugadzirwa kwematehwe, iyo inoderedza saizi yepore uye inowedzera kuwanda kweganda, nekudaro ichiwedzera kumira kwemvura uye kusimba. Kazhinji, iyo pH kukosha kweganda rakashama mushure mekudzikisira kupfava ndeye 7.5 ~ 8.5, kuitira kuti ganda regrey rikodzere mamiriro ekushanda ekunyorovesa maitiro, zvinodikanwa kugadzirisa pH kukosha kweganda rakashama, kudzikisira kusvika 2.5 ~ 3.5, kuitira kuti ive yakakodzera chrome tanning. Nzira huru yekugadzirisa pH kukosha ndeye acid leaching, iyo inonyanya kushandisaformic acid. Formic acid ine mamorekuru madiki, inopinda nekukurumidza, uye ine masking maitiro pane chrome tanning fluid, kuitira kuti kusanganiswa kwezviyo zvidiki zvedehwe zvakanaka panguva yekutsvaira. Inowanzoshandiswa pamwe chete ne sulfuric acid panguva ye acid leaching.
