Gulu la zinthu zamitundu yosiyanasiyana
Gulu la Master ndi mtundu watsopano wa utoto wopangidwira makamaka zinthu za polima, womwe umadziwikanso kuti kukonzekera utoto. Umapangidwa ndi zinthu zitatu zofunika: utoto kapena utoto, zonyamulira ndi zowonjezera. Ndi gulu lopangidwa ndi utoto lomwe limapezeka poyika utoto wochuluka kwambiri pa ma resini ndipo limatha kutchedwa mtundu wosakanikirana. Chifukwa chake, mphamvu yake yopaka utoto ndi yayikulu kuposa ya utoto wokha. Mwachidule: Gulu la master la utoto ndi gulu lopangidwa ndi utoto wochuluka kwambiri pa resini.
01 Kapangidwe
Utoto kapena utoto
Mitundu ya utoto imagawidwanso m'magulu a utoto wachilengedwe ndi utoto wa inorganic
Mitundu ya utoto yomwe imagwiritsidwa ntchito kwambiri ndi iyi: phthalocyanine red, phthalocyanine blue, phthalocyanine green, lightfast bright red, macromolecular red, macromolecular yellow, permanent yellow, permanent purple, permanent red, azo red, etc.
Mitundu ya utoto yomwe imagwiritsidwa ntchito kwambiri ndi iyi: cadmium wofiira, cadmium wachikasu, titanium dioxide, carbon black, iron oxide wofiira, iron oxide wachikasu, etc.
Wonyamula katundu
Chonyamulira ndiye maziko a mtundu wa masterbatch. Ma masterbatch apadera amitundu nthawi zambiri amasankha utomoni womwewo ndi utomoni wazinthu zomwe zimapangidwa ndi chonyamulira, ndipo kugwirizana pakati pa ziwirizi ndiko kwabwino kwambiri. Komabe, kusinthasintha kwa chonyamulira kuyeneranso kuganiziridwa nthawi yomweyo.
Chotulutsira
Kuti pakhale kufalikira kofanana kwa utoto ndikuletsa kuti usaundane, malo osungunuka a utoto ayenera kukhala otsika kuposa a utoto, ndipo ayenera kukhala ogwirizana bwino ndi utoto komanso kugwirizana bwino ndi utoto. Mafuta osungunuka omwe amagwiritsidwa ntchito kwambiri ndi awa: sera ya polyethylene yolemera pang'ono komanso stearate.
Zowonjezera
Mitundu monga yoletsa moto, yowunikira, yoletsa mabakiteriya, yoletsa kusinthasintha kwa kutentha, yoletsa mabakiteriya ndi ina, pokhapokha ngati kasitomala wapempha, nthawi zambiri siili ndi zowonjezera zomwe zili pamwambapa mu mtundu wa masterbatch.
02 Ubwino
a.Kuti utoto ukhale wosavuta kufalikira mu chinthucho. Pakupanga mitundu ya masterbatches, utoto uyenera kukonzedwa kuti uwonjezere kufalikira kwawo ndi mphamvu yopaka utoto. Chonyamulira cha masterbatch yapadera ya utoto ndi chofanana ndi mtundu wa pulasitiki wa chinthucho, chomwe chimagwirizana bwino. Pambuyo potenthetsa ndi kusungunuka, tinthu ta utoto titha kufalikira bwino mu pulasitiki ya chinthucho.
b.Ndikothandiza kusunga kukhazikika kwa mankhwala a utoto. Ngati utoto ugwiritsidwa ntchito mwachindunji, umayamwa madzi ndi oxidize chifukwa cha kukhudzana mwachindunji ndi mpweya panthawi yosungidwa ndi kugwiritsidwa ntchito. Komabe, atapangidwa kukhala mitundu yambiri, chonyamulira utomoni chimachotsa utoto kuchokera ku mpweya ndi chinyezi, zomwe zimatha kusunga mtundu wa utotowo kwa nthawi yayitali.
c.Onetsetsani kuti mtundu wa chinthucho ndi wokhazikika. Tinthu ta Masterbatch timeneti ndi tofanana ndi tinthu ta resin, zomwe zimapangitsa kuti tizitha kuyeza mosavuta komanso molondola. Sitimamatira ku chidebecho posakaniza ndipo timasakanikirana bwino ndi resin. Chifukwa chake, kukhazikika kwa kuchuluka kwa zinthu zomwe zawonjezeredwa kumatha kutsimikizika, motero kutsimikizira kukhazikika kwa mtundu wa chinthucho.
D.Tetezani thanzi la ogwira ntchito. Utoto nthawi zambiri umakhala ngati ufa ndipo umauluka ukawonjezedwa ndi kusakanikirana. Ukapumidwa ndi thupi la munthu, umakhudza thanzi la ogwira ntchito.
ndi.Sungani malo oyera
f.Zosavuta kugwiritsa ntchito
Fakitale yathu imagwiritsa ntchito mitundu yosiyanasiyana popanga mapaipi apulasitiki, zomwe zimathandiza kupanga mapangidwe osiyanasiyana ndikupangitsa mapaipi kukhala okongola kwambiri.
