Zvinosuruvarisa, chando-chena tulle ichigadzira hwindo rinotanga hachigari saizvozvo nenzira yekusingaperi, kuwana ruvara ruchena kana ruvara rwehuni kwenguva yakareba nekuda kweguruva, sitofu inopisa, chiedza chezuva uye zvimwe zvinhu. Uye kushambidzika kwemazuva ose hakugoni kudzorera iyo yekare yakachena. Asi nzira yekudzorera sei chigadziro kune chaicho chaicho chitsva, kuchenesa maketeni ? Ngationei dzimwe nzira dzinoshanda.
Nhasi nzira dzekuchenesa machira
Mazuva ano, chemakemikari inoita kuti vagadziri vemasikati vawane nzira dzakasiyana-siyana dzekugadzirisa matambudziko emhuri nekushamba, kubvisa kusvina uye kubvisa. Nzira iri nyore ndeyokushandisa whitener yakadai se "Belize". Usati washandisa, inodonhedzwa mune imwe nzvimbo yemvura uye yakaiswa mune iyi sarudzo inenge yehafu yeawa.
Pane zvakawanda zvinokonzera kukanganisa kune nzira iyi. Chokutanga, chibvumirano chinowana unhu hunopinza hunhu, hunoda kuvanza. Chechipiri, kushandisa nzira iyi kamwechete, iwe uchafanira kushandisa chlorine nguva dzose, nokuti dzimwe nzira hadzingabatsiri.
Iko kunewo mamwe makemikari mabhiriji mukugadzirwa. Basa ravo nderokudzikisa mune chimwe chikamu nemvura uye kuvhara maketeni kweimwe nguva. Uye paunorwisana nematanda, kushandiswa kwemasvina kunoshandiswa muzvikamu zvakanyanyisa.
Usakanganwa kuti hazvibviri kushandisa makemikari anokonzera uye tsvina dzinobvisa nemhando dzose dzemaketeni, sezvinongoita dzimwe nguva inouraya kune mavara matete. Nokudaro, mune dzimwe nguva, unoda kuziva kuti ungakurumidza sei kuchenesa pamba uchishandisa mishonga.
"Babushkiny" nzira dzekuchenesa machira
Maitiro makuru evanhu ekurwisana ne-yellowing yemaketeni ndeye zelenka, munyu, ammonia, hydrogen peroxide, bluu, starch uye sabhani yekuchenesa.
Chimbofunga nzira dzose dzemusha dzekudzivirira mabhodha kuitira kuti:
- Kuchenesa mutsvuku nemuchero: kuderedza madonhwe mashanu mumvura shoma uye uwedzere iyi sarudzo kuti usuke mvura mushure mekugeza.
- Nzira yekudzidzira sei kugunun'una nemunyu? Kutanga iwe unofanidza kuvhara chidzitiro chevhu, ndokuisa mune remvura yakagadziriswa yemunyu neupfu, yakagadzirirwa muhuwandu hwepasipuni 4-5 yemunyu uye upfu hwe 5 litita emvura. Chengetedza mhinduro muawa gumi nemaviri, mushure mezvo icharamba ichigeza nekusuka chigadzirwa. Imwe nzira ndeyokushambidza machira nenzira yakajairika, wozoisa munyuro yemunyu kwemaminitsi gumi nemashanu. Kuisuka hazvidiwi. Nzira huru yeyiloni tulle.
- Nzira yekuchenesa sei ne hydrogen peroxide uye ammonia (iyi nzira inokodzera micheka yekotoni): mumvura ine kutonhora kwe60 ° C, yega 1 kikapu yeammonia uye 2 maspuniji e3% ehydrogen peroxide, sanganidza uye udzikise zvigadzirwa zvakanaka. Mushure memaminitsi makumi maviri musvure uye mirei makoma, musingadi kupindira.
- Nzira yekuchenesa sei mumushini wokuchenesa nemubatsiro webhuruu: usati washamba, unoda kuwedzera kapu yebhuruu (yakaoma kana mvura) mumvura inoshandiswa. Pachinosuka, mishonga inozoita zvose pachayo-tora bhuruu uye simesa machira nayo.
- Kuzadza nesarasi (kutengesa kubva kune caprone uye organza): gurutsa mubhesheni nemvura inodziya 250 g yemashizha ematamato, mushure mekushambidza, gadzirisa chidzitiro mubhedha kwemaminetsi mashomanana chete, wozorora. Nzira iyi inongorodza maitiro, asiwo anovabatsira kuchengetedza maitiro uye anoita kuti maketeni asati asvike kune ivhu, seguruva richagara pane starch panzvimbo yezvigadzirwa, uye munguva inotevera zvichava nyore kushambidza chidzitiro.
- Sesi yeimba yekuchenesa machira: inofanira kunge yakagadzirwa uye yakavharwa muhari yemvura. Mhinduro yekubikira inofanira kubviswa kubva pabheti, yakasanganiswa nemvura inotonhorera kuti iwane musanganiswa unodziya uye kuvhara mukati maro kwemaawa mashanu kusvika ku7. Pashure pacho, inofanira kunge yakashambidzwa uye yakashambidzwa.
