I-insulation yangaphandle yodonga lwangaphandle ukubeka ijazi lokushisa elishisayo esakhiweni.Lesi sigqoko sokushisa esishisayo akufanele sigcine ukushisa kuphela, kodwa futhi sibe sihle.Njengamanje, uhlelo lwezwe lami lwangaphandle lokugqumisa udonga ikakhulukazi luhlanganisa uhlelo lokugqumisa ibhodi le-polystyrene enwetshiwe, uhlelo lokugqumisa ibhodi le-polystyrene olukhishiwe, uhlelo lokufakela i-polyurethane, i-latex powder polystyrene particle insulation system, i-inorganic vitrified bead insulation system, njll. Ukufakwa kwangaphandle kokushisa akufanelekile kuphela ukushisisa izakhiwo ezindaweni ezisenyakatho ezidinga ukulondolozwa kokushisa ebusika, kodwa futhi nezakhiwo ezinomoya opholile ezindaweni eziseningizimu ezidinga ukufakwa kokushisa ehlobo;ilungele kokubili izakhiwo ezintsha kanye nokuvuselela ukonga ugesi kwezakhiwo ezikhona;ukulungiswa kwezindlu ezindala.
① Umthelela wokwengeza impushana ye-latex ehlakazeka kabusha odakeni olusanda kuxutshwa lwesistimu yokufaka udonga lwangaphandle:
A. Nweba amahora okusebenza;
B. Ukuthuthukisa ukusebenza kokugcinwa kwamanzi ukuze kuqinisekiswe ukugeleza kukasimende;
C. Thuthukisa ukusebenza.
② Umthelela wokwengeza impushana ye-latex ehlakazeka kabusha odakeni oluqinile lwesistimu yokufaka udonga lwangaphandle:
A. Ukunamathela okuhle ebhodini le-polystyrene namanye ama-substrates;
B. Ukuguquguquka okuhle kakhulu kanye nokumelana nomthelela;
C. Ukungena kahle komhwamuko wamanzi;
D. I-hydrophobicity enhle;
E. Ukumelana nesimo sezulu esihle.
Ukuvela kwe-adhesives ye-tile, ngezinga elithile, kuqinisekisa ukuthembeka kokunamathisela kwe-tile.Imikhuba yokwakha ehlukene kanye nezindlela zokwakha zinezidingo ezihlukene zokusebenza kokwakhiwa kwezinamatheliso zamathayili.Ekwakhiweni kwamanje kwe-tile yasekhaya yokunamathisela, indlela yokunamathisela ewugqinsi (i-adhesive yokunamathisela evamile) iseyindlela yokwakha evamile.Uma le ndlela isetshenziswa, izidingo ze-adhesive tile: kulula ukugubha;kulula ukufaka i-glue, ummese ongagxili;I-viscosity engcono;okungcono anti-slip.Ngokuthuthukiswa kobuchwepheshe bokunamathela kwe-tile kanye nokuthuthukiswa kobuchwepheshe bokwakha, indlela ye-trowel (indlela yokunamathisela emincane) nayo iyamukelwa kancane kancane.Ukusebenzisa le ndlela yokwakha, izidingo ze-adhesive tile: kulula ukugubha;Ummese onamathelayo;ukusebenza okungcono kwe-anti-slip;ukumanzisa okungcono kwama-tile, isikhathi eside sokuvula.
① Umthelela wokwengeza impushana ye-latex ehlakazeka kabusha odakeni olusanda kuxutshwa lokunamatheliswa kwethayela:
A. Nweba isikhathi sokusebenza nesikhathi esingalungiseka;
B. Ukuthuthukisa ukusebenza kokugcinwa kwamanzi ukuze kuqinisekiswe ukugeleza kukasimende;
C. Thuthukisa ukumelana ne-sag (impushana ye-latex eguquliwe ekhethekile)
D. Thuthukisa ukusebenza kahle (okulula ukwakha ku-substrate, kulula ukucindezela ithayela ku-adhesive).
② Umphumela wokwengeza impushana ye-latex ehlakazeka kabusha odakeni oluqinile lwe-adhesive:
A. Inonamathela kahle kuma-substrates ahlukahlukene, okuhlanganisa ukhonkolo, ukhonkolo, ukhuni, amathayela amadala, i-PVC;
B. Ngaphansi kwezimo zezulu ezihlukahlukene, inokuvumelana nezimo okuhle.
