Ngaba ukhe waphawula into engaqhelekanga: okukhona impahla ikumgangatho ophezulu, kokukhona ithanda ukujika umbala. Jonga iimpahla zodidi oluphezulu - zonke zizinto ezithambileyo. Zifuna unonophelo olucokisekileyo; kungenjalo, ziya kubonakala zigugile emva kokunxiba nje okumbalwa. Yiyo loo nto ubunewunewu bokwenene bunjalo!
Kutheni ezinye iimpahla ezinophawu ziphuma umbala lula kangaka?
Impendulo: Iimpahla zasehlotyeni okanye ezikufutshane nolusu ezivela kwiimveliso ezaziwayo zihlala zinengxaki yokopha kwemibala, kuquka imibala eqinileyo kunye nezinto eziprintiweyo ezinemibala emininzi. Ingqiqo eqhelekileyo ingacebisa ukuba iimpahla ezinophawu kufuneka zibe nombala okhawulezayo.
Ngenxa yokuqhubela phambili kwezobuchwepheshe, abavelisi beempahla zexabiso eliphezulu bahlala bekhetha iidayi ezisondelelene nezinto zendalo. Ezi dayi azinambala ungakhawuleziyo, kodwa azinabungozi ebantwini kwaye zinobuhlobo nokusingqongileyo.
Musa ukumanzisa okanye ukuqokelela ezi mpahla ixesha elide, kwaye uphephe ukuzihlamba kubushushu obuphezulu. Iidayi ze-non-azo zisetyenziswa kakhulu namhlanje. Iilaphu eziprintiweyo nezidayiweyo ngeedayi ezithile ze-non-azo zibonisa umbala ophantsi. Zombini iilaphu ezidayiweyo kunye neendwangu eziprintiweyo zinokopha umbala ngexesha lokuhlamba. Le ngxaki idla ngokuvela kwiimpahla zasehlotyeni kunye neempahla ezikufutshane nolusu, kwaye ixhaphake kakhulu kwiimpahla zabasetyhini. Hlamba ezi zinto ngeesepha ezingathathi cala. Gqibezela imisebenzi yokuhlamba ngokukhawuleza nangokuqhubekayo. Musa ukumanzisa okanye ukuqokelela iimpahla emanzini, kwaye ungaze usebenzise amanzi ashushu.
Zeziphi iilaphu ezidla ngokuphuma umbala?
Impendulo yeNgcali:
Ukopha kombala ngexesha lokuhlamba kulandela iipatheni ezithile. Iilaphu ezenziwe ngemicu yendalo zopha umbala lula kunezo zenziwe ngemicu yeekhemikhali, ingakumbi imicu yokwenziwa. Iilaphu zekotoni, ilinen, isilika kunye noboya zisengozini yokulahleka kombala kuneepolyamide, ipolyester, i-acrylic kunye nezinye izinto ezifanayo.
Isilika kunye nekotoni ziphezulu kakhulu ngenxa yokopha kwemibala. Okulandelayo, amalaphu adaywe kakhulu kwaye anemibala eqaqambileyo adla ngokuphuma igazi.
Imibala emnyama, enzulu, ebomvu eqaqambileyo, eluhlaza okwesibhakabhaka eqaqambileyo, nombala omfusa oqaqambileyo kunye nemibala efanayo iphuma lula; amalaphu anombala okhanyayo nongacacanga awanalo ithuba lokulahlekelwa ngumbala. Umzekelo, i-overcoat enzima yoboya obucocekileyo enemibala eqaqambileyo ngokuqinisekileyo iya kuphelelwa ngumbala, ngelixa i-overcoat efanayo ye-acrylic ayisayi kuphelelwa. Ngokufanayo, ilokhwe yesilika emnyama iphelelwa ngumbala emanzini, ngelixa ilokhwe yepolyester efanayo iphelelwa ngumbala kwaphela.
Iindlela zokuhlamba ukuze kuthintelwe ukopha nokunyamalala kombala
Ukulahleka kombala kwilaphu elidayiweyo kunxulumene neempawu zedayi kunye neendlela zokudaya eziprintiweyo. Uninzi lweedayi eziqhelekileyo ziyanyibilika lula emanzini, ingakumbi emanzini anesepha, amanzi ashushu kunye namanzi ane-alkaline. Iidayi ziyaphela xa ilanga likhanya xa ilaphu limanzi.
Ukuze ugcine umbala, hlamba ngamanzi abandayo usebenzisa isepha engathathi cala efana nesepha yesilika, ishampu okanye isepha yezitya. Musa ukusebenzisa umgubo wokuhlamba impahla, isepha yebha okanye ukufunxa amanzi ashushu.
Hlamba impahla emnyama nekhanyayo ngokwahlukeneyo ukuze uphephe ukungcolisa. Yongeza icephe elincinci letyuwa kwibhakethi yamanzi afudumeleyo ukuze uhlambe; ungaze usebenzise amanzi ashushu kakhulu.
Hlamba kakuhle ngamanzi acocekileyo emva nje kokuhlamba. Musa ukushiya isepha okanye intsalela yesepha ye-alkaline kwilaphu ngokucwilisa ixesha elide.
Yomisa ngomoya kwindawo epholileyo, enomoya owaneleyo; thintela ukukhanya kwelanga ngqo.
Isayensi ebangela ukopha kombala wengubo
Kutheni impahla iphuma umbala? Ngamafutshane: ukungakhawulezi kombala ngokwaneleyo. Kwiingcali zokuprinta nokudaya, ukungakhawulezi kombala okungalunganga kuvela kwizizathu ezahlukeneyo. Iimpawu eziqhelekileyo zokuqina kombala ziquka ukungakhawulezi kokuhlamba ngesepha, ukungakhawulezi kokucoca, ukungakhawulezi kokukhanya, ukungakhawulezi kokukhanya / ukuqina kwe-redox, ukungakhawulezi kokufaka i-ayina, ukungakhawulezi kokukhupha kunye nokukhawulezi kokukhanya okudibeneyo. Phakathi kwezi, ukuhlamba ngesepha, ukuxubha, ukukhanya, amanzi kunye nokukhawulezi kokukhupha zezona zibonakaliso ziphambili kubasebenzi belaphu.
Imigangatho yokuqina kombala
Ukuqina kombala kubhekisa ekumelaneni kwelaphu kwiingcinezelo ezahlukeneyo ngexesha lokwenziwa nokusetyenziswa. Iisampulu zivavanywa elebhu kwaye zivavanywa ukuba zitshintsha umbala kwaye zifakwe idayi. Uvavanyo luxhomekeke kwiisikali ezingwevu ezisemgangathweni zamazwe ngamazwe zokutshintsha umbala kunye nokufakwa idayi. Isikali esingwevu sigubungela amabakala amahlanu aphambili ukusuka kwiBanga loku-1 (elibi kakhulu) ukuya kwiBanga lesi-5 (elingcono kakhulu), kunye namabakala aphakathi, eyaziwa ngokuba yi "nkqubo yenqanaba lesithoba lebanga lesihlanu".
Uvavanyo lweBanga lesi-4 lubonisa ukuphambuka okuncinci. Uninzi lweenkcukacha zoshishino lujolise kwiBanga lesi-4 okanye lesi-3 kwesi-4. Ngokwahluka kwemibala kunye nokukhawuleza kombala, iBanga lesi-4 lithathwa njengelamkelekileyo ngokubanzi.
Iindidi zokukhawuleza kombala
Ukukhawuleza kokuhlamba isepha
Impahla ifuna ukuhlanjwa ngeesepha, ngoko ke ukuhlanjwa ngesepha yenye yezona zinto zibalulekileyo ezibonisa ukuhlanjwa ngemibala. Ukuhlanjwa ngesepha kusebenza ngomsebenzi we-surfactant onciphisa uxinzelelo lomphezulu wamanzi ukuphucula ukungena kwamanzi, kunye ne-emulsification yokusasaza umhlaba onamafutha emanzini okuhlamba.
Ngexesha lokudaya, iidayi zinamathelana neefayibha. Ezinye iidayi zenza iifayibha eziqinileyo ze-covalent chemical kunye neefayibha. Ezinye iimolekyuli zedayi zihlala nje ngokukhululekileyo phezu kwemiphezulu yeefayibha. Ezi dayi zibotshelelwe bubuthathaka ziyaphuma emanzini anesepha zize ziphume emanzini okuhlamba. Ukungakhawulezi kakuhle kokuhlamba isepha kuthetha ukungafakwa kakuhle kwedayi; iimpahla ziba namabala emva kokuhlamba.
Ukukhuhla ngokukhawuleza
Ukuqina kokuhlikihla kugubungela ukuqina kokuhlikihla okomileyo kunye nokuqina kokuhlikihla okumanzi. Xa amalaphu ehlikihla kwezinye iindawo, ukudluliselwa kombala kwenzeka ngeendlela ezimbini: iidayi ezikhululekileyo ziyahlikihla kwizinto eziqhagamshelanayo, okanye iziqwenga zefayibha ezidayiweyo ziyahlukana kwaye zinamathele kwezinye iindawo. Ukuqina kokuhlikihla luvavanyo oluyimfuneko phantse kuzo zonke iilaphu zelaphu.
Ukulahleka kombala we-wet-rub kubangelwa kakhulu ngumbala okhululekileyo kumphezulu. Umbala okhululekileyo kakhulu uvela kwizinto ezimbini eziphambili: ukufunxwa kwedayi okungaphantsi kunye nokugcwala kwedayi kakhulu. Iifomyula zomthunzi onzulu zihlala zisebenzisa iidayi ezixineneyo ezishiya umbala ogqithisileyo kumphezulu ngokulula.
Ukulahleka kombala we-dry-rub kubonakala rhoqo kwilaphu elicoliweyo nelixutyiweyo. Imiphezulu yazo ephakanyisiweyo nerhabaxa ivelisa ukungqubana okuphezulu, ikhulula umbala we-lint kunye nombala womphezulu. Amalaphu agudileyo adla ngokusebenza kakuhle kuvavanyo lwe-dry-rub.
Ukukhawuleza okukhaphukhaphu
Ukufiphala kwefoto kuyinkimbinkimbi: iidayi zifunxa iiphoton, zivuselelwe kwaye zenze ii-photochemical reactions eziphula izakhiwo zeemolekyuli, zivelise utshintsho lombala kunye nokufiphala. Ukuqina kokukhanya kwelaphu kuxhomekeke ikakhulu kwisakhiwo seekhemikhali zedayi, imeko yokuhlanganiswa, imeko yokubopha kunye nokudibanisa imibala. Ukukhetha idayi efanelekileyo kubalulekile.
I-substrate yelaphu ikwachaphazela ukuqina kokukhanya. Umzekelo, isilika yonakala xa ilanga ligqithisile. Izinto ezikhanyayo ezifana nomhlophe ongacacanga kunye nekhrimu zinobuthathaka ekukhanyeni kwaye zinokuba neengxaki zokuqina kokukhanya.
Ukubila ngokukhawuleza
Ukukhawuleza kokubila kuvavanya utshintsho lombala welaphu kunye nokudaywa kweengubo ezikufutshane phantsi koxinzelelo kunye nobushushu kwizisombululo zovavanyo ezine-histidine. Iingubo zasehlotyeni ezikufutshane nolusu zichatshazelwa kakhulu kukubila, ngoko ke ukusebenza kokubila kufuneka kuqwalaselwe xa kusenziwa.
Ukungakhawulezi kwamathe
Ukuqina kwamathe luvavanyo olukhethekileyo kwimpahla yeentsana. Iintsana zinokumunca okanye zihlafune amalaphu. Amathe anamanzi, iikhabhohayidreyithi, iiphosphates kunye neeproteni. Lo mgangatho uthintela idayi okanye izinto eziyingozi ekukhutshweni ngamathe nokuginywa, nto leyo ekhusela ukhuseleko losana.
