Izicelo

Isetyenziselwa ukulinganisa ipropati yokulahleka kolwelo lwempahla ezingezizo ezolukiweyo. I-non-woven medium elinganisiweyo ibekwe endaweni yayo, ibeke isampuli edibeneyo kwipleyiti ethambekileyo, ilinganisa xa inani elithile lomchamo wokwenziwa lihamba liye ezantsi kwisampuli edityanisiweyo, ulwelo oludlula kwi-nonwoven medium lufunxwa yi-standard absorption, ifunxwa ngokulinganisa utshintsho oluqhelekileyo lobunzima obuphakathi ngaphambi nasemva kovavanyo lokusebenza kokukhukuliseka kolwelo lwesampuli engezizo ezolukiweyo.

Umgangatho weNtlanganiso

Ipharamitha yoBugcisa

1. Ibhentshi yovavanyo iphawulwe ngemigca emibini emnyama yokubhekisa, umgama phakathi kwayo yi-250±0.2mm;
Umgca ophantsi, 3±0.2mm ukusuka esiphelweni sebhentshi yovavanyo, yindawo yesixhobo sokufunxa esiphelweni;
Umgca ophezulu ngumgca osembindini wetyhubhu yokukhupha amanzi malunga ne-25mm ukusuka phezulu kwisampulu yovavanyo.
2. Ukuthambekela kweqonga lovavanyo yi-25 degrees;
3. Isithako: okanye isixhobo esifanayo (esisetyenziselwa ukulungisa indawo esembindini wesampuli) esinokulungisa isampuli kwindawo eyi (140 s 0.2) mm ngokulinganayo kumgca wesalathiso.
4. Indawo ephakathi (ukuqinisekisa ukukhululwa kolwelo kwityhubhu);
5. Isakhelo sokuxhasa esinephedi yokufunxa eqhelekileyo kwisiphelo esisezantsi sesampulu yovavanyo;
6. Ityhubhu yeglasi: ububanzi bangaphakathi yi-5mm;
7. Isiseko seringi;
Isixhobo sokuthontsiza: itini kwi (4±0.1) s kwimeko eqhubekayo yolwelo (25±0.5) g yolwelo lovavanyo ngetyhubhu yovavanyo yeglasi;
