Zipangizo za PVA Zosungunuka ndi Madzi
Zipangizo za PVA zosungunuka m'madzi zimasinthidwa pogwiritsa ntchito polyvinyl alcohol (PVA), starchndi zina zowonjezera zomwe zimasungunuka m'madzi. Zipangizozi ndi zinthu zosawononga chilengedwendi madzi osungunuka komanso zinthu zomwe zimatha kuwola, zimatha kusungunuka kwathunthu mu water. Mu chilengedwe, tizilombo toyambitsa matenda pamapeto pake timaswa zinthuzo kukhala carbon dioxide ndimadzi. Akabwerera ku chilengedwe, sadzakhala ndi poizoni ku zomera ndi zinyamakomanso.
Kutentha kosungunuka m'madzi ndi liwiro la zipangizozo zitha kusinthidwa kuti zigwirizane ndi zomwe mukufunaZofunikira za mer, apa 2108C ikhoza kusungunuka m'madzi ozizira (25℃ ± 10℃), ndi 2110H chitiniSungunulani m'madzi otentha (>60℃)
Zinthu Zogulitsa:
1: Liwiro lotha kusungunuka mwachangu, kutentha kosungunuka ndi liwiro losungunuka zimatha kusinthidwa.
2: Ikhoza kuwonongeka ndi kutha m'chilengedwe, ndipo ikhoza kuwonongeka kwathunthu kukhala carbon dioxide ndi madzi.
3: Zinthuzo sizili poizoni konse: ndizotetezeka komanso sizili poizoni; sizivulaza anthu, nyama ndi zomera; zitha kukhudzana ndi chakudya.
4: Kapangidwe kabwino kwambiri ka makina, magwiridwe antchito abwino otsekera kutentha.
5: Zipangizozi zili ndi mphamvu yokoka kwambiri, chitetezo chabwino, komanso magwiridwe antchito apamwamba kwambiri otchinga mpweya, zomwe zimaletsa kufalikira kwa tizilombo toyambitsa matenda toopsa.
Ntchito:
Makanema opangidwa ndi zinthuzi angagwiritsidwe ntchito popanga matumba ogulira zinthu, matumba otayidwa,
matumba opaka, matumba ochapira zovala osungunuka m'madzi, ndi zina zotero.
Phukusi/Kusungirako:
Chikwama chopanda chinyezi komanso chopangidwa ndi pepala/pulasitiki chokhala ndi thumba la pulasitiki
phukusi, 25 kg/thumba, phukusi lotsekedwa pa kutentha kwa chipinda chitsimikizo cha malonda kwa zaka ziwiri.
Zindikirani: Mankhwalawa ali ndi chinyezi, choncho chonde gwiritsani ntchito mwamsanga mukamaliza kugwiritsa ntchito.
Tsegulani phukusi, kapena sungani chinthu chomwe sichinagwiritsidwe ntchito ndi matumba apulasitiki.
Lembani uthenga wanu apa ndipo mutitumizireni
