Ivy forms thiaj li hu ua nplaum cag. Cov nroj tsuag nce toj siv cov khob nqus dej no los thauj lawv tus kheej ntawm lub tsev facades. Yog hais tias cov ntoo raug tshem tawm, cov cim tsis zoo tseem nyob. Lawv tuaj yeem raug tshem tawm siv txoj kev tshwj xeeb uas yuav tsum tau ua kom haum rau saum npoo.
Yuav ua li cas ivy residue tshem tawm ntawm facades?
Muaj ntau txoj hauv kev los tshem cov ivy residue ntawm facades: sandblasters, high-pressure cleaners, qhuav dej khov, roj burners thiab hydrochloric acid. Kev xaiv cov txheej txheem tsim nyog yog nyob ntawm substrate thiab rhiab heev ntawm qhov chaw.
Cov txheej txheem no muaj nyob:
- Sandblaster: zoo tagnrho rau rhiab facades
- High-pressure cleaner: rau qhov chaw ruaj khov
- Dry ice: ib puag ncig tus phooj ywg thiab maj mam tu
- Gas burner: yog tias hluav taws kub hnyiab tau raug txiav tawm
- Hydrochloric acid: as a last resort
Sandblaster
Cov hauv paus residue tuaj yeem raug tshem tawm siv cov dav hlau cua compressed uas txau xuab zeb rau ntawm lub ntsej muag. Sandblasters muaj qhov zoo ntawm kev ua tiav hauv cov cheeb tsam uas nyuaj rau kev nkag mus. Lawv yog cov maj mam thiab kuj haum rau rhiab clinker ci facades.
High-pressure ntxhua khaub ncaws
Hauv txoj kev no, cov ivy residue yog yaj thiab ntxuav tawm siv lub dav hlau tawv dej. Cov dej kub los yog qhov sib ntxiv ntawm cov kua qaub-dissolving cov tshuaj ntxuav kom muaj zog. Cov tawv nqaij tawv tuaj yeem raug tshem tawm nrog cov av blaster (€ 16.00 ntawm Amazon), uas txuas nrog lub tshuab nqus tsev siab. Qhov saum npoo yog feem ntau puas vim muaj kev kub siab. Clinker pob qij txha lossis masonry tsis tuaj yeem tiv taus lub dav hlau, uas ua rau muaj kev puas tsuaj.
Dry ice
Cov ice pellets qhuav ua los ntawm khov nitrogen yog txau mus rau lub façade ntawm lub siab. Cov txheej txheem no blasts deb cov hauv paus hniav los ntawm kev sib cuag nrog cov minus 80 degree ice particles, tsis cuam tshuam rau subsurface. Txawm tias qhov chaw rhiab heev xws li clinker cib tuaj yeem ntxuav tau maj mam. Cov pellets tig mus rau hauv lub xeev gaseous, yog li tsis muaj residue nyob tom qab. Yog hais tias lub masonry twb raug kev puas tsuaj, lub dav hlau siab tuaj yeem ua kom puas cov khoom crumbly ntxiv.
Gas burner
Flaming cov nplaum cov hauv paus hniav ua rau lawv qhuav, yog li cov residue tuaj yeem raug tshem tawm nrog txhuam. Ceev faj yog qhia thaum ua hauj lwm nrog nplaim taws, vim cov ntaub ntawv insulating nyob rau hauv lub tsev phab ntsa tuaj yeem smolder unnoticed vim cua sov thiab ntes hluav taws.
Hydrochloric acid
Plastered phab ntsa thiab cov pob qij txha tuaj yeem ntxuav nrog diluted hydrochloric acid, uas koj kis tau rau ntawm lub ntsej muag nrog txhuam. Nws softens lub calcareous subsoil thiab xyuas kom meej tias ivy keeb kwm loosen tom qab noj cov nyhuv. Ua ntej koj txhuam cov seem, koj yuav tsum yaug cov kua qaub seem nrog dej los ntawm lub vaj hose. Nco ntsoov tias txoj kev no ua rau muaj kev pheej hmoo rau koj kev noj qab haus huv thiab ib puag ncig.
