Umngundo kwiSealant yeBathroom: Kutheni icwecwa ngokulula kunye nempembelelo yayo ekude{0}}

Umngundo ophuma ngokulula kwisitywina sokuhlambela unokubonakala ngathi yinkathazo encinci, kodwa eneneni ivela kunxibelelwano phakathi kwee-microbes, ukufuma, kunye nokuthotywa kwezinto. Lo mba usasazeke kumakhaya kwihlabathi jikelele{1}ukusuka kwimimandla efumileyo yonxweme yase-United States ukuya kumagumbi amancinci eYurophu naseAsia. Uphando lwezenzululwazi luqinisekisa ukuba le ngxaki ayizenzekelanga; iqhutywa ziimeko zokusingqongileyo kunye nokunciphisa umzimba.

Kutheni uMngundo Uphumelela kwiiSealants zeBathroom

Amagumbi okuhlambela abonelela ngemekobume efanelekileyo yokukhula komngundo ngenxa yokufuma okuzingisileyo, ubushushu, kunye nenkunkuma ephilayo. Ii-silicone sealants, ezidla ngokusetyenziswa malunga neebhafu, iisinki, kunye neeshawari, zidala i-microclimates exhasa ukukhula komngundo. Iipropathi zazo zokugquma zigcina zipholile kancinci kunezingqongileyo, zikhuthaza ukujiya.

Uphononongo luka-2019 olunesihloko esithi "Decontamination of Mould{1}}Affected Environments," olwenziwe liZiko leNew Zealand of Environmental Science and Research (ESR), liqaqambise ukuba iijoyinti zesilicone kwigumbi lokuhlambela kungenzeka ziphuhlise ukungunda okumnyama xa ukufuma kudlula i70%. Abaphandi basePorirua baphawule ukuba isepha scum kunye nezinye iidiphozithi ezivaleleke kwizitywini zibonelela ngezondlo ezikhawulezisa ukukhula komngundo. Oku kuchaza ukuba kutheni ukungunda kuqala kuvela ecaleni kwemigca yesitywina kuneethayile.

Indlela uMngundo ebangela ngayo i-Sealant kwi-Flake

Ukukhululeka kokuxobuka kwe-sealant engumngundo kubangelwa yindlela ezikhula ngayo umngundo. Umngundo awuhlali nje phezu komhlaba; ingena nzulu kwisealant. I-spores zenza i-mycelium{2}}efana nenethwekhi esasazeka ngaphantsi komphezulu, yenza buthathaka imathiriyeli ukusuka ngaphakathi ukuya ngaphandle.

Ingxelo ye-2018 yi-US National Institute of Standards and Technology (NIST), ebizwa ngokuthi "uPhuhliso lweMicrobial kwi-Construction Sealants," ibonise ukuba iimbumba eziqhelekileyo ezifana ne-Aspergillus niger zivelisa i-enzymes ephula iipolymers ze-silicone. Lo msebenzi we-enzymatic wenza umaleko oqhawukileyo, oethe-ethe-ukwenza ukungunda kubonakale kulula ukucocwa{5}}ngelixa ushiya ukosuleleka okunzulu kungachukunyiswa.

Ngokufanayo, uphononongo luka-2020 olwenziwa yiFraunhofer Institute yaseJamani yeFiziksi yoKwakha, “Ukwenziwa kweBiofilm kwiiSanitation Sealants,” kufumanise ukuba ukukhula komngundo kunokutshintsha ubume bepolymer yezitywini. Abaphandi baseHolzkirchen bafumene i-60% ukuya kwi-70% yokunciphisa amandla, yiyo loo nto eyonakeleyo i-sealant flakes kunokuba ihlale injalo.

Indima yokufuma nokuthotywa kwezinto

Kwiindawo zokuhlambela, ii-sealants zihlala zibonakaliswe kwimijikelezo yokumanzisa kunye nokomisa. Ngokuhamba kwexesha, oku kukhokelela kwiintanda ezincinci ezivumela i-spores kunye namanzi ukuba angene nzulu kwizinto eziphathekayo.

Uphononongo luka-2021 olwenziwa yiYunivesithi yasePortsmouth yeSikolo sobuNjineli boLuntu eUnited Kingdom, enesihloko esithi "Ukunganyangeki kweFungal ye-Sealants kwiNdawo eFumeke kakhulu," yafumanisa ukuba i-silicone sealants esemgangathweni ilahlekelwa ukuya kuthi ga kwi-40% yamandla abo okubambelela emva komjikelo wokufuma okuphindaphindiweyo. Oku kulahleka kokuncamathela kuguqula i-sealant ibe yinto abaphandi abayibiza ngokuthi "umgwaqo omkhulu we-biofilm," okwenza ukuba i-fungi isasazeke ngokulula.

Ezi zinto zifunyanisiweyo ziqinisekisa ukuba ukuxobuka kwe-moldy sealant ayingomcimbi nje ongaphezulu{0}}yingxaki yesakhiwo ebangelwa luxinzelelo lwendalo esingqongileyo kunye nomsebenzi wemicrobial.

Iimpembelelo zeMpilo kunye noLwakhiwo

Iintsholongwane zokungunda zingaphezulu nje kwenkxalabo yobuhle; zikwabeka imingcipheko enkulu yempilo. I-Arhente yoKhuseleko lweNdalo yase-US (i-EPA) ichonge ikhonkco phakathi kokuvezwa komngundo wangaphakathi kunye nokwaliwa, imiba yokuphefumula, kunye ne-asthma. Iindidi ezithile, ezifana neStachybotrys chartarum, zikhupha ii-mycotoxins ezinokuhamba emoyeni xa ziphazamisekile, zinyusa umngcipheko wokuphefumla.

Ingxelo yoMbutho wezeMpilo weHlabathi (i-WHO) ka-2023 malunga nokufuma kwangaphakathi ityhila ukuba ukuvezwa kokungunda kunokubangela izifo zokuphefumla kuninzi lwemizi yasezidolophini kwihlabathi liphela.

Ngokwesakhiwo, i-sealant eyonakeleyo inokuvumela amanzi ukuba angene kwiithayile kunye nezinye izinto. Oku kuvuza kufihliweyo kungonakalisa imigangatho, iindonga, kunye nezakhiwo ezingaphantsi{1}kaninzi zingahoywa de kufuneka ukulungiswa okuxabisa kakhulu.
