Kodi chifukwa chotani chokhazikika pa matope owuma?

Nthawi yokhazikitsa matope osakanikirana mu National Standard ndi maola 3-8, koma nthawi yokhazikitsa matiti ambiri osakanikirana ndi osakhazikika. Matoma ena amakhazikitsidwa kwa nthawi yayitali ndipo samakhazikika kwa nthawi yayitali. Koma nthawi zambiri zimasokonekera mtsogolo. Nanga bwanji matope owuma-osakaniza ali ndi nthawi yosakhazikika?

Zifukwa zoyambira nthawi yayitali youma - Choyamba, zitha kukhala chifukwa cha kusintha mu nyengo ndi nyengo, monga kutentha kochepa, nyengo yamvula, ndipo imapangitsa kuti matope asakhumudwe kwa nthawi yayitali. Chifukwa chachiwiri chikhoza kukhala kuti chowonjezera cha hydroxypypyl methylcellulose ndi zochuluka kwambiri. Hydroxypypyl methylcellulose imakhala ndi madzi olimba. Ngati kuchuluka kwa hydroxypypyl methylcellulose ndi zochuluka kwambiri, chinyezi cha matope chidzakhala zambiri. Zotsatira zake, matope sadzakhumudwa kwa nthawi yayitali, omwe angakhudze ntchito yomanga.

Zifukwa zoperewera kwakanthawi kouma: yoyamba ndi chifukwa cha nyengo, nyengo yatentha, kutentha kumakhala kwakukulu, ndipo kutulutsa kumakhala kofulumira. Chachiwiri ndi zinthu zachilengedwe, maziko ake ndi owuma, ndipo palibe madzi omwe adathira asanamangidwe. Wachitatu ndi kuchuluka kwa madzi otsika a ma hydroxypygyl, kapena zochepa zowonjezera zimatsogolera ku kusungidwa kwamadzi kosayenera kwa matope.

Njira Zopewera ndi Zowongolera: Choyamba, mtundu wa kugwiritsiridwa kwa hydroxpyl ayenera kuyesedwa mosamala, cellulose yosungidwa bwino iyenera kugwiritsidwa ntchito ndipo kuchuluka kwa kuphatikizika kumayenera kulamuliridwa mosamalitsa. Ndikofunikira kusintha kuchuluka kwa cellulose yowonjezeredwa molingana ndi nyengo zosiyanasiyana, nyengo yosiyanasiyana, ndi zida zosiyanasiyana za makhoma. Lachiwiri ndikulimbitsa masitepe pa Tsitsi kuti muchepetse zambiri zomanga.
