1) Vees lahustuvus:<\/p>\n

K\u00fclmas vees lahustuv kile eeldab, et vees on v\u00f5imalik lahustada vett \u00fcle 4 \u2103. Mida kiiremini see lahustub, seda parem. Mida v\u00e4hem j\u00e4\u00e4ke j\u00e4\u00e4b p\u00e4rast lahustamist j\u00e4rele, seda parem. Mida selgem on lahustunud vesi, seda parem.<\/p>\n

2) V\u00e4limuse kvaliteet:<\/p>\n

Mida sujuvam on m\u00e4his, seda parem. Rulli v\u00e4lispinnal ei tohiks olla ilmseid ebatasasusi ega kortse. Mida lamedamad on rullifilmi kaks otsapinda, seda parem, \u00b12 mm piires. Kile pinnal ei tohiks olla defekte, nagu mullid, perforeeringud, r\u00e4bu ja mustad laigud.<\/p>\n

3) Mehaaniline tugevus:<\/p>\n

T\u00f5mbetugevus peab olema \u00fcle 25 MPa. Liiga v\u00e4he on lihtne \u00e4ra t\u00f5mmata. Murdev\u00f5ime peab olema \u00fcle 180%. V\u00e4iksem on pehmendav. Ristk\u00fcliku rebenemiskindlus peab olema umbes 80KN\/m. Vastasel juhul on see purunemisel rabe.<\/p>\n

4) S\u00e4ilitamisaeg: Vees lahustuv kile, mille kvaliteet on stabiilne, v\u00f5ib ladustada rohkem kui 1-2 aastat (ilma niiskuseta).<\/p>\n
