1.Jonga: Xa ukhetha iikomityi zephepha ezilahlwayo, musa ukujonga nje ukuba ikomityi yephepha imhlophe okanye hayi.Musa ukucinga ukuba umbala omhlophe, ngakumbi ucoceko.Ukuze wenze iikomityi zibonakale zimhlophe, abanye abavelisi beekomityi zephepha bongeza inani elikhulu le-fluorescent whitening agents.Nje ukuba ezi zinto ziyingozi zingene emzimbeni womntu, ziya kuba zi-carcinogens ezinokubakho.Iingcali zicebisa ukuba xa ukhetha ikomityi yephepha, kungcono ukuthatha ifoto yayo phantsi kwesibane.Ukuba indebe yephepha ibonakala eluhlaza okwesibhakabhaka phantsi kwesibane se-fluorescent, kuthetha ukuba i-agent ye-fluorescent idlula umgangatho, kwaye abathengi kufuneka bayisebenzise ngokuqaphela.

2.I-Knead: Umzimba wekomityi uthambile kwaye awuqini, ngoko lumkela ukuvuza kwamanzi.Ukongeza, khetha iikomityi zephepha ezinodonga olungqingqwa kwaye oluqinileyo.Iikomityi zephepha ezinobunzima obuphantsi bomzimba ziya kuthamba kakhulu xa zipinkiwe.Emva kokugalela amanzi okanye iziphuzo, ziya kuphazamiseka kakhulu xa zithathwa, okanye zingakwazi ukuphakanyiswa, ezichaphazela ukusetyenziswa.Iingcali zithi iikomityi zephepha ezikumgangatho ophezulu ziyakwazi ukugcina amanzi iiyure ezingama-72 zingavuzi, ngelixa iikomityi zephepha ezikumgangatho ophantsi ziya kuvuza kwisiqingatha seyure.

3.Ivumba: Umbala wodonga lwekomityi mhle, qaphela ityhefu ye-inki.Iingcali zolawulo lomgangatho zibonise ukuba iikomityi zephepha zipakishwa kunye.Ukuba zifumile okanye zingcolisekile, ukungunda kuyakwenzeka ngokuqinisekileyo, ngoko ke iikomityi zephepha ezifumileyo mazingasetyenziswa.Ukongeza, ezinye iikomityi zephepha ziya kuprintwa ngeepatheni ezinemibala kunye namagama.Xa iikomityi zephepha zihlanganiswe ndawonye, ​​i-inki engaphandle kwendebe yephepha iya kuchaphazela ngokuqinisekileyo umaleko wangaphakathi wekomityi yephepha ejikelezileyo.I-inki ine-benzene kunye ne-toluene, eyingozi empilweni.Thenga iikomityi zephepha ezingena-inki okanye eziprinta ngaphantsi ngaphandle.

4.Sebenzisa: Yahlula phakathi kweekomityi ezibandayo kunye neekomityi ezishushu.Ngamnye kubo unemisebenzi yakhe.Ekugqibeleni iingcali zabonisa ukuba iikomityi zephepha ezisetyenziswa ngokuqhelekileyo zinokwahlulwa zibe ziindidi ezimbini: iikomityi zesiselo esibandayo neekomityi zesiselo esishushu.Nganye inendima yayo.Xa “ibekwe ngendlela engafanelekanga”, inokuba nefuthe kwimpilo yabathengi.
