Okokuqala, ukujonga imbonakalo: ukuthunga itawuli kulungile, umphetho ucocekile, ububanzi buhambelana, buthe tyaba kwaye buthe nkqo, abuyi-oblique kwaye abujikwanga, ukuqina kuhambelana, ukuphakama kweenwele kucocekile, i-velvet ring ilungile;Itawuli yesandla kwinqanaba lamehlo, iringi yevelvet iqaqambile kwaye icocekile, kunqabile ukucocwa kwangaphandle kwe-lint kulungile.Umbala osulungekileyo oqaqambileyo, ngaphandle kobunzulu bento engalinganiyo ubengcono.
Okwesibini, ukubamba isandla: itawuli yomqhaphu elungileyo ivakala ithambile, ithambile kwaye akukho mvakalelo igudileyo.Bamba kwinqindi elithambileyo kunye ne-elastic, ungabetheli ilinti.
Okwesithathu, ivumba: Iitawuli ezintle azinuki.Ukuba kukho iphunga lekhandlela okanye iphunga le-ammonia, libonisa ukuthambisa kakhulu;Ukuba kukho incasa emuncu, ixabiso le-PH lingadlula umgangatho;Ukuba kukho i-taste pungent, kuthetha ukuba ukusetyenziswa kwe-agent agent equkethe i-formaldehyde, i-free formaldehyde precipitation.
Okwesine, ukulinganisa i-hygroscopicity: ukuxhoma ithawula, isandla sifakwe emanzini kwithawula, amanzi awayi kuqengqeleka, ebonisa ukufunxa ngokukhawuleza kunye nokusabalalisa, i-hygroscopicity enhle;Ukuba kukho amaconsi amanzi, kucetyiswa ukuba ithawula kwi-softener overdose okanye ukucocwa akwanelanga.
Okwesihlanu, ukukhawuleza kombala: i-80℃ yokuqala okanye amanzi ashushu kangako kwisitya, kwaye emva koko kwitawuli ukuya phezulu nasezantsi ekuhlambeni amaza.Amanzi kwisitya akaguquguquki ngokunjalo;Ukuba kukho umbala owelayo, kubonisa ukuba umgangatho wokuprinta kunye nokudaya umpofu kwaye unobungozi kwimpilo yabantu.
Ngoko ke, sincoma ukuba uzame ukuthenga iithawula kwiindawo zokuthenga ezinkulu, iivenkile ezinkulu okanye iivenkile, kwaye ukhethe iimveliso ezivela kubavelisi abaqhelekileyo.Imveliso yethawula efanelekayo inophawu oluqhelekileyo, ibonisa umenzi, indawo yemvelaphi, inombolo yefowuni, uphawu lokuthengisa, umgangatho wokubulawa, indlela yokuhlamba kunye nokunye, kwaye ixabiso lifanelekile, imali ifanelekile.
