Mankhwala Odziwika Bwino a Mankhwala Ophera Tizilombo

Mankhwala ophera tizilombo nthawi zambiri amabwera m'njira zosiyanasiyana monga ma emulsions, suspensions, ndi ufa, ndipo nthawi zina mitundu yosiyanasiyana ya mankhwala omwewo imapezeka. Ndiye ubwino ndi kuipa kwa mitundu yosiyanasiyana ya mankhwala ophera tizilombo ndi chiyani, ndipo ndi chiyani chomwe chiyenera kusamalidwa mukamagwiritsa ntchito?

1, Makhalidwe a mankhwala ophera tizilombo

Mankhwala ophera tizilombo osakonzedwa amakhala zinthu zopangira, zomwe zimafuna kukonzedwa ndi kuwonjezera zowonjezera kuti zigwiritsidwe ntchito. Mlingo wa mankhwala ophera tizilombo umadalira choyamba pa mphamvu zake za physicochemical, makamaka kusungunuka kwake ndi momwe zimakhalira m'madzi ndi zinthu zachilengedwe.

Ngakhale kuti mankhwala ophera tizilombo amatha kukonzedwa m'njira zosiyanasiyana, poganizira kufunika, chitetezo, komanso kuthekera kogwiritsa ntchito ndalama, chiwerengero cha mitundu ya mankhwala omwe angakonzedwe kuti agwiritsidwe ntchito ndi ochepa.

2, Mitundu ya mankhwala ophera tizilombo

①. Ufa (DP)

Ufa ndi ufa wopangidwa ndi ufa wokhala ndi kusalala kwina komwe kumapangidwa posakaniza, kuphwanya, ndi kusakaniza zinthu zopangira, zodzaza (kapena zonyamulira), ndi zina zochepa zowonjezera. Kuchuluka kwa ufa nthawi zambiri kumakhala pansi pa 10%, ndipo nthawi zambiri sikuyenera kuchepetsedwa ndipo ungagwiritsidwe ntchito mwachindunji popopera ufa. Ungagwiritsidwenso ntchito posakaniza mbewu, kukonza nyambo, dothi la poizoni, ndi zina zotero. Ubwino ndi kuipa: Siwoteteza chilengedwe mokwanira, pang'onopang'ono kuchepetsa kugwiritsa ntchito.

②. Tinthu tating'onoting'ono (GR)

Ma granules ndi ma granules osasunthika opangidwa mwa kusakaniza ndi kuyika granules pa zinthu zopangira, zonyamulira, ndi zina zochepa zowonjezera. Zosakaniza zothandiza za mankhwalawa ndi pakati pa 1% ndi 20%, ndipo nthawi zambiri zimagwiritsidwa ntchito popopera mwachindunji. Ubwino ndi kuipa: Ndi yosavuta kufalitsa, yotetezeka komanso yokhalitsa.

③．Ufa wonyowa (WP)

Ufa wonyowa ndi mtundu wa ufa womwe umakhala ndi zinthu zopangira, zodzaza kapena zonyamulira, zonyowa, zotulutsa mpweya, ndi zina zothandizira, ndipo zimapeza kusalala kwina kudzera mu njira zosakaniza ndi kuphwanya. Ufa wonyowa ukhoza kusakanizidwa ndi madzi kuti upange choyimitsira chokhazikika komanso chomwazika bwino kuti upopere. Wokhazikika: 98% imadutsa mu sefa ya maukonde a 325, yokhala ndi nthawi yonyowa ya mphindi ziwiri zamvula yochepa komanso kuchuluka kwa kuyimitsidwa kopitilira 60%. Ubwino ndi kuipa: imasunga zosungunulira zachilengedwe, imagwira ntchito bwino, ndipo imathandizira kulongedza, kusunga, ndi kunyamula.

④．Ma granules osakanikirana ndi madzi (WG)

Ma granule omwazika m'madzi amapangidwa ndi zinthu zopangira, zinthu zonyowetsa, zinthu zomwazika, zinthu zodzipatula, zinthu zokhazikika, zomatira, zodzaza kapena zonyamulira. Mukagwiritsidwa ntchito m'madzi, imatha kusweka ndikufalikira mwachangu, ndikupanga njira yomwazika yolimba kwambiri. Ubwino ndi kuipa: Yotetezeka, yogwira ntchito bwino, yochepa, komanso yoyimitsidwa kwambiri.

⑤．Mafuta a Emulsion (EC)

Emulsion ndi madzi amafuta ofanana komanso owonekera bwino opangidwa ndi mankhwala aukadaulo, zosungunulira zachilengedwe, ma emulsifier ndi zina zowonjezera. Akagwiritsidwa ntchito, amasungunuka m'madzi kuti apange emulsion yokhazikika yopopera. Kuchuluka kwa emulsifier concentrate kumatha kuyambira 1% mpaka 90%, nthawi zambiri pakati pa 20% mpaka 50%. Ubwino ndi kuipa: Ukadaulowu ndi wokhwima pang'ono, ndipo palibe sedimentation kapena stratification pambuyo powonjezera madzi.
