Urea M'malo/Urea m'malo LH-391H
Chiyambi cha Urea Substitute:
-Cholowa m'malo cha Urea chingagwiritsidwe ntchito m'malo mwa urea pakusindikiza kokhazikika.
-LH-391H urea m'malo ndi mtundu wapadera wa mamolekyulu.Ndizoyenera kwambiri kusindikiza zotakataka za thonje kapena nsalu ya viscose.
Zofunika Kwambiri ndi Zopindulitsa Zomwe Zimachitika:
◆ Ali ndi ntchito za hydroscopic, kusungunuka ndikuthandizira kutupa kwa ulusi.
◆ Itha kusintha urea kuti igwiritsidwe ntchito posindikiza zotakataka za thonje kapena nsalu ya viscose popanda kukhudza mtundu womwe wapeza.
◆ Angathe kuchepetsa ammonia m'madzi otayidwa.
LH-391H Urea M'malo:
| Katundu | Mtengo |
| Mawonekedwe Athupi | Madzi |
| Maonekedwe | Zamadzimadzi zowoneka bwino zopanda mtundu |
| pH (1% yankho lamadzi) | 6.5-8.5 |
| Digiri ya shuga (%) | 27.0-30.0 |
| Chikhalidwe cha Ionic | Ofooka cationic |
Kugwiritsa Ntchito Urea M'malo:
1. Chinsinsi:
| Madzi | X g |
| Urea | 0g-10g |
| M'malo mwa Urea LH-391H | 10 g-0g |
| Pewani mchere S | 1g |
| Sodium hexametaphosphate | 0.5-1 g |
| Sodium carbonate | 1-3g pa |
| Thickening wothandizira | Yg |
| Reactive dyestuff | Z g |
| Zonse | 100g pa |
LH-391H akhoza m'malo urea kwathunthu, kapena wothira urea ndi 1: 1, 1: 2 kapena chiŵerengero, yeniyeni mlingo ayenera kusinthidwa ndi chofunika kapena processing chikhalidwe cha makasitomala.
2. Njira yoyenda:
Kukonzekera phala—Kusindikiza kwa rotary kapena lathyathyathya-Kuyanika(100-110℃, 1.5-2min)-Kutentha (101-105 ℃, 8-10 min)→Kutsuka
Kusamalitsa
Malangizo ogwiritsira ntchito ndi chitetezo:
1. Limbikitsani kuyeza ndi kuchepetsedwa kwa othandizira motsatana pokonzekera phala, kenaka yikani imodzi ndi imodzi ndikugwedeza mokwanira.
2. Limbikitsani mwamphamvu kugwiritsa ntchito madzi ofewa mu dilution, ngati madzi ofewa sapezeka, kukhazikika kumayenera kuyesedwa musanapange yankho.
3. Pambuyo pa dilution, sayenera kusungidwa kwa nthawi yaitali.
4. Kuti muwonetsetse chitetezo, muyenera kuwonanso Material Safety Data Sheets musanagwiritse ntchito mankhwalawa pansi pamikhalidwe yapadera.MSDS ikupezeka kuchokera ku Lanhua.Musanagwiritse ntchito zina zilizonse zomwe zatchulidwa m'mawuwo, muyenera kupeza zambiri zokhudzana ndi chitetezo chazinthu ndikuchitapo kanthu kuti mutsimikizire kuti mukugwiritsa ntchito.
Phukusi & Kusunga:
Pulasitiki ng'oma ukonde 120 makilogalamu, akhoza kusungidwa kwa miyezi 6 pansi firiji ndi hermetic chikhalidwe popanda kukhudzana ndi kuwala kwa dzuwa.Kuti muwonetsetse kuti zinthuzo zikusungidwa, chonde onani nthawi yomwe chinthucho chikutsimikizika, ndipo ziyenera kugwiritsidwa ntchito zisanachitike.Chidebecho chiyenera kutsekedwa mwamphamvu pamene sichikugwiritsidwa ntchito.Iyenera kusungidwa popanda kukhudzana kwa nthawi yayitali ndi kutentha kwakukulu ndi kuzizira, zomwe zingayambitse kulekana kwa mankhwala.Ngati mankhwala asiyanitsidwa, gwedezani zomwe zili mkati.Ngati mankhwala achisanu, sungunulani pa kutentha ndi kusonkhezera pambuyo thawed.
Tcherani khutu
Malingaliro omwe ali pamwambawa amachokera ku maphunziro athunthu omwe amachitidwa pomaliza.Komabe, alibe mangawa pankhani ya ufulu wa katundu wa anthu ena ndi malamulo akunja.Wogwiritsa ntchitoyo ayenera kuyesa ngati chinthucho ndi pulogalamu yake ndi yoyenera pazifukwa zake zapadera.
Ndife, koposa zonse, tilibe udindo pa minda ndi njira zogwiritsira ntchito zomwe sizinalembedwe ndi ife polemba.
Malangizo oyika chizindikiro ndi njira zodzitetezera zitha kutengedwa kuchokera papepala lachitetezo.
