FOGGINGuruhu rwubukorikoriikizamini ahanini cyibintu bihindagurika byegeranye ku kirahure, cyangwa aluminiyumu, uburyo bwo kwipimisha.Uburyo bwo kohereza urumuri burashobora gukoreshwa cyangwa uburyo bwuburemere, uburyo bwuburemere buroroshye gukora kandi burakoreshwa cyane, muri rusange muri 2mg kugirango bujuje ubuziranenge.
Ibiri mubintu bihindagurika mubikoresho byimodoka imbere ni ikintu cyingenzi kigira ingaruka kumiterere yimbere no gutwara ibinyabiziga bigaragara.Mubikorwa byumusaruro no kunoza imikorere yaImodoka imbere, ibintu bito bya molekile birashoboka ko byinjizwa muri byo, kandi ibintu byinjijwe birahinduka, cyane cyane iyo ubushyuhe buri mumodoka buri hejuru.Ibintu bito bya molekile byahindagurika imbere yimodoka imbere cyangwa bireremba mu kirere, bihumanya ikirere cy’imbere mu modoka, byangiza ubuzima bw’abantu nyuma yo guhumeka, cyangwa guhurira ku madirishya y’imodoka, bigira ingaruka mbi ku murongo utwara ibinyabiziga no guhungabanya umutekano wo gutwara.Kubwibyo, uburyo bwo kugerageza ibirimo ibintu bihindagurika mubice byimbere yimodoka nikibazo gisanzwe mubikorwa byimodoka.Uyu munsi Bensen araguha intangiriro irambuye.
●Amateka yikizamini cyimikorere ihindagurika:
1992, Komite ishinzwe ibinyabiziga by’Ubudage na Komite isanzwe y’ibikoresho bya Sintetike byatanze urugero, DIN 75201
1994, Sosiyete y'Abanyamerika y'Abashinzwe Imodoka, SAE J1756

Ku bipimo by'ibizamini bya fogge bitaragera ku mategeko mpuzamahanga ahuriweho, urashobora gusobanukirwa buri buryo bwikizamini kugirango uhitemo ibidukikije bikwiye nyuma yuburyo bwikizamini.
●Ingaruka ziterwa nigihu gihindagurika hamwe nakamaro ko gutahura:
1. Gazi ihindagurika mumadirishya yimodoka cyangwa idirishya ryidirishya, bikaviramo kutagaragara neza, bigira ingaruka kumyerekezo yumushoferi numutekano wo gutwara.
2. Bimwe mubintu bihindagurika byangiza umubiri wumuntu kandi bigira ingaruka kubuzima bwabashoferi nabagenzi.Kugenzura mu buryo bushyize mu gaciro ibintu bihindagurika, imikorere yibicu bihindagurika (bizwi kandi nkibikorwa bya fogging) ikizamini cyibikoresho bikoreshwa mumodoka imbere birakenewe cyane, agaciro k'igihu kirenze ibipimo bisanzwe byibikoresho ntibizakoreshwaImodoka imbere.
Uruhukubera uruhare rwibintu byakozwe n'abantu hamwe nibindi bintu, hejuru hazagaragara ibicu cyangwa imbibi zijimye zasohotse, bita uruhu "cream".Nkumunsi wimvura yimpu,uruhuizagusha ifu yera (“cream cream”);uruhu rurimo ibintu byinshi bya aside irike, hanyuma ibicuruzwa byuruhu mubihe bimwe na bimwe bizagaragara ko ari "amavuta ya cream";n'uruhu “sulfure cream” izwi kandi nka kanseri y'uruhu, bigoye gutsinda;uruhu igihe kirekire mukuzigama byoroshye gukura ibidukikije (ubushyuhe bwinshi nubushyuhe bwinshi bwo guhumeka, burimo intungamubiri zintungamubiri, nibindi), ubuso bwabwo buzagaragara hamwe namabara atandukanye (imvi, umuhondo wijimye, icyatsi kibisi) ibibara, bita "cream cream".

Gukura k'uruhu ku ruhu bifite impamvu eshatu zikurikira.Ubwa mbere, uruhu rurimo intungamubiri zo gukura.Nkuko twese tubizi, uruhu rwibicuruzwa bitunganijwe bya polymer bisanzwe, ibiyigize nyamukuru ni proteyine ya kolagen hamwe n’ibinure, mugutunganya uruhu, byongeyeho umubare munini wamavuta yinyamanswa n’ibimera hamwe n’amavuta, imyunyu ngugu na minerval na casein, nibindi ., izi nisoko nziza yintungamubiri zisabwa kugirango imikurire ibe.Icya kabiri, kuba hari umubare munini wa spore yibumba mu kirere.Iyi spore yibumba ireremba hamwe numuyaga, hamwe no guhura, iyo biguye hejuru yuruhu, kubera kubona imirire ikungahaye, byoroshye gukura no kubyara.Icya gatatu, gutunganya uruhu no kubika no gutwara ibintu, bifasha gukura no kubyara ibumba.Ubushyuhe bwo gukura bwubushyuhe, ubushuhe hamwe na PH ni binini cyane, bikwiranye no gukura kwubushyuhe 25 ~ 35 ℃, ubuhehere bugereranije buri hejuru ya 75%, agaciro ka PH muri rusange kari hagati ya 1.5 ~ 11, agaciro ka PH gakwiye ni 6.0.Muburyo bwo gutwika, nko kwibiza aside, gukanika, gusubiramo no kurangiza, bilet hamwe nimpu zuzuye biri mubihe bya acide, kandi imiterere yimpu yimpu itera hygroscopique ikomeye hamwe namazi menshi (amazi arimo uruhu rwuzuye; ni 14% ~ 18%).Ukurikije ibihe by'ubushyuhe n'ubushyuhe bwinshi bwo mu kirere mu majyepfo y'Ubushinwa, uruhu n'ibicuruzwa byacyo biroroshye cyane gukura, kandi mu majyaruguru hari n'ibishoboka.Ibidukikije bishyushye nubushuhe muburyo bwo kubika no gutwara nabyo bitanga ibihe byiza kubibumbano birebire byuruhu.
●Ihame ryo kumenya igihu gihindagurika
Ibikoresho by'imbere mu modokaIrashobora kuba ibintu bihindagurika mukirere nyuma yubushyuhe, umwuka ushyushye uhura nibintu bikonje, ibintu bihindagurika kandi bigahuzwa mumazi yometse kubintu bikonje.Inzira yo guhuha ni ihindagurika ryibintu - inzira ya kondegene.
●Uburyo bwo kumenya ibicu bihindagurika
1 method Uburyo bwiza.
Ibigereranirizo mu gikombe cyibicu byashyutswe na gaze ihumeka yegeranye ku isahani y’ikirahure gike, ugereranije agaciro ka gloss mbere na nyuma yo kwegeranya isahani yikirahure hanyuma ukabara, agaciro ka fogi yikigereranyo karashobora kuboneka.
2 method Uburyo bwa Haze.
Ibigereranirizo mu gikombe cyibicu byashyutswe na gaze ihumeka yegeranye ku isahani y’ikirahure gike, ugereranije agaciro k’umwotsi mbere na nyuma yo guhuza isahani yikirahure hanyuma ukabara, agaciro k'igicu k'icyitegererezo karashobora kuboneka.
3 method Uburyo bwo gupima.
Gazi yavuye mu cyitegererezo mu gikombe cy'ibicu irashyuha kandi igashyirwa ku ifu ya aluminiyumu yo mu bushyuhe buke, kandi uburemere bugahinduka mbere na nyuma yo guhuza ifu ya aluminiyumu bipimwa kugira ngo haboneke uburemere bw'igihu hamwe na kondegene y'icyitegererezo.
●Uruhu "cream" ingamba zo gukemura
Kubibazo byuruhu "cream", urufunguzo nukwirinda, umusaruro wa sosiyete ya Bensenuruhu rwubukorikoriwibande ku kwangirika na buri nzira yo gukaraba, kugirango wirinde amavuta karemano atangwa na "cream".Muri icyo gihe, witondere cyane ibikoresho bya shimi mugupima uruganda no gutunganya ibinyobwa binure, hamwe no guhuza neza, kugenda kwinshi kwinzoga zamavuta ya sintetike hamwe namavuta yibimera byahinduwe nkibinyobwa binini byamavuta, urugero rukwiye rwamavuta yubumara kugirango wirinde cyangwa ubuze kubaho kwa "cream";anti-mildew igomba kandi kuvugwa mubikorwa byo gutunganya no kubika, kongeramo anti-mildew, guhumeka ububiko, byumye;kugenzura imiterere yubushyuhe Kugira ngo wirinde "cream" yimiterere ikwiye igaragara.
Ibicuruzwa byuruhu bikoreshwa mubuzima bwa buri munsi nka "cream yumunyu" birashobora guhanagurwa nigitambaro gitose kandi gisohotse burundu, hanyuma ugahanagurwa na poli yinkweto za emulisile nyuma yo kumisha.Kuri "amavuta ya cream" aboneka ether cyangwa yumutse ako kanya nyuma yohanagura nigitambaro cyoroshye kugirango ukureho.Kuri "mold cream", menya neza ko ibicuruzwa biguma ahantu humye, ubushyuhe buke, guhagarika umwuka, kwanduza no kugira isuku.Kandi "cream sulfure" kubera ko yitwa "kanseri" y'uruhu, iyo imaze gushingwa biragoye cyane kuyikuramo, bityo rero muburyo bwo gutunganya uruhu kugenzura.
