Ukunyamekela izicathulo kuyimfuneko kungekhona nje ukujonga kakuhle, kodwa ukwandisa ubomi benkonzo. Yingakho ngaphezu kweenkulungwane ezili-5 ezedlule, i-ointment yezicathulo yenziwe. Ngethuba lokubusa kukaCharles II, isiFrentshi sakha iindlela ezilula zokucoca izicathulo, ezibandakanya izithako ezifana neqanda, i-oven oil, iviniga okanye ibhiya. Isixhobo, ngokuqinisekileyo, sasinancinci, kodwa kwakungekho nto ekhethekileyo kuyo. Emva kokumiswa okupheleleyo, le ndoda yaphela ukukhanya kwaye yafumana umthunzi womzimba. Kwaye isiNgesi siphumelele ukuphucula esi sixhobo kwaye siphumelele kwisiphumo esihle kwaye sisakholelwa ukuba isihloko sabantu abafumene iigcino kufanele sibe ngabanye.
Okwangoku, kukho abaninzi abakhiqizi abavelisa izihlangu zesikhumba ezivela kwiindidi ezahlukahlukeneyo. Nangona kunjalo, abalandeli beeNgesi zakudala base-English baye basinda, kwaye nanamhlanje basebenzisa i-molasses, i-wax, i-bone soot, i-linseed, i-castor ne-turpentineoyile, i-shellac, njl njl. UNichola, izitimela zikaKelner noBruner.
Zonke iindidi ze-gutalin zanamhlanje zingahlelwa ngohlobo olusisiseko, apho indima idlalwe ngu:
- ukuxhoma ngokuxhomekeke kumanzi, apho amaninzi amaninzi ayinasiphelo. Iindlela ezinjalo zijongana nezicathulo ezibonakalayo kuphela, zingaphuculanga kuyo yonke imeko yayo;
- Iindlela ezisekelwe kwioli ye-turpentine (indebe kuthiwa yi-turpentine) iyatshisa kwaye ibe neflethi ephawulekayo. Xa usebenzisa nokugcina, kufuneka uhambelane nemimiselo ethile kunye nemimiselo yokhuseleko. I-ointment yezicathulo zesikhumba ezisekelwe kwi-turpentine zidla ngokupakishwa kwiitini ze-tin kunye nezikhonkwane eziqinileyo ezikhuselekileyo zokuthintela ukuqhuma kwe-turpentine;
- Gutalin esekelwe kwioli ye-mink yindlela ebiza kakhulu yokucoca izicathulo.
Kuza kubekho, kukho iikramiti ezenziwe ngokusebenzisa iteknoloji ye-hybrid - isiseko kubo ngamanzi kunye ne-turpentine.
Ungakhetha njani ioli ecocekileyo?
Iimarike zamagqabi ezintshontsho zanamhlanje zingabelana ngazo:
- ukhilimu ococekileyo, ocebisa ukuba usebenzise ngexesha elifudumeleyo. I-emulsion kunye ne-emulsion yamanzi esekelwe ukunyamekela izicathulo ayinalo i-solvents (ininzi ngokuqhelekileyo ukwenzela ukuba amanzi asetyenziswe), ngoko ke isimo sabo sengqondo kwiingwele zibucayi kakhulu. Ezi zixhobo zicetyiswa ukuba zisetyenziswe xa zinyamekela izicathulo zemodeli ezibiza. Inqanaba lokukhuselwa kumanzi kumimulsions liphantsi kakhulu kuneoli ecocekileyo, nangona kunjalo ukulungiswa kwamanzi kwenza ulusu lube lukhuni ngakumbi kwaye lube lukhuni;
- i-cream egciniweyo, esetyenziselwa ukunakekelwa kweentsuku zemihla ngemihla ekwindla nakusibusika. Ezi mpiliso zisekelwe kwizinto eziphilayo ezifana ne-wax, i-fat fat, i-colorants kunye ne-solvents. Ukufumana i-ointment ecocekileyo ye-organic, kufuneka ikhunjulwe ukuba inomlilo ocolileyo.
Ngesizathu esithile, iindawo ezithandwa kakhulu ngabathengi iingubo
Ukuze ukhethe ukhilimu olungileyo, ngaphambi kokuthenga, kufuneka ufunde ngokucophelela ukubunjwa kwawo. Ukuba umxholo weoli ukhulu ngaphezu kwama-40%, ukhilimu unokukhusela izicathulo kumanzi kunye nokwenza ulusu lube lukhulu. Umxholo ophezulu we-silicone okanye i-wax ibonisa ukuba ukhilimu ukhanyisa. Iisombululo zikunceda ukukrazula uthuli kunye nobuncwane, kunye nepeyinti - ukutshintsha indawo.
