MODDAHOI GANDZUDO

MODDAHOI GANDZUDO, mavode, ki baroi nobud kardani mikroorganizmhoi bemoriovar istifoda meshavand. Dar vaqti intikhobi moddahoi khimiyavi, muayyan kardani miqdoru tarkibi onho va muhlati doruposhi khususiyathoi angezandai bemoriro ba nazar megirand. Ba M. g.-i nisbatan mamul khloramin, ohaki khlordor, gipokhloriti kaltsiy va formalin mansuband.
Hloramin khokai safed (yo zardcha) ast. Onro dar shishahoi siyohi mahkam yo khaltahoi polietileni (dar joi torik) nigoh medorand. Beshtar dar shakli mahluli 0,2 – 3-foiza baroi gandzudonii khona, zarfho va g. istifoda mebarand. Muhlati doruposhi 30 –60 daq. ast. Mahluli khloraminro dar zarfi sarpushdore, ki rushnoiro nameguzaronad, to 15 ruz nigoh doshtan mumkin ast.
Ohaki khlordor safed ast; az tasiri garmi, rushnoi va nami zud tajziya meyobad. Binobar in, onro dar zarfi havo va rushnoinoguzari dahonash mahkam (dar joi khushk, ki haroratash az 20°S baland naboshad) nigoh doshtan lozim. Ohaki khlordorro ham khushk (baroi bezarar gardonidani pasafkandi bemoron; tanosubash 1:5 dar 1 soat) va ham dar shakli mahluli 10 – 20-foiza (baroi gandzudoii hojatkhona, chohi partovho, akhlotqutti, safed kardani devor), inchunin ba sifati mahluli 05 – 1-foizai sof (baroi gandzudoii binoho, asbobu anjomi khona, zarfhoi ruzgor, chizu chorai hojatkhona; muhlati doruposhi ba hisobi miyona 30 – 60 daq.) kor mefarmoyand. Mahluli ohaki khlordor zud vayron meshavad, binobar in onro faqat pesh az istifoda tayyor kardan lozim ast. Az tasiri ohaki khlordor mato va filizot zarar mebinad, az in sabab onhoro bo digar moddahoi khimiyavi boyad gandzudoi kard. Ohaki khlordorro dar binohoi rutubatnok va shamolpanah niz istifoda namebarand.
Gipokhloriti kaltsiy khokai kristallii safed buda, dar shakli mahluli 0,1 – 1-foiza baroi gandzudoii zarfho, vanna, dastshuyak va g. (muhlati doruposhi 30 – 60 daq.) istifoda meshavad; khokai onro baroi bezarargardonii pasafkandi bemoron (tanosubash 1:5 yo 1:10) niz kor mefarmoyand.
Formalin mahluli 40-foizai formaldegid buda, bui tezi makhsus dorad. Onro baroi gandzudoii kameravi, inchunin poyafzoru dastpushakho dar asnoi bemorihoi zanburugii pust istifoda mebarand.
