Dibutyl phthalate (DBP)
Dibutyl phthalate ndi pulasitiki yokhala ndi kusungunuka kwamphamvu kwa mapulasitiki ambiri. Yogwiritsidwa ntchito pokonza PVC, imatha kupatsa chinthucho kufewa bwino. Ingagwiritsidwenso ntchito mu nitrocellulose coating. Ili ndi kusungunuka kwabwino, kufalikira, kumatira komanso kukana madzi. Ikhozanso kuwonjezera kusinthasintha, kukana kusinthasintha, kukhazikika, komanso kugwira ntchito bwino kwa pulasitiki. Ili ndi mgwirizano wabwino ndipo ndi pulasitiki yomwe imagwiritsidwa ntchito kwambiri pamsika. Ndi yoyenera mitundu yosiyanasiyana ya rabara, cellulose butyl acetate, ethyl cellulose polyacetate, vinyl ester ndi ma resin ena opangidwa ngati mapulasitiki. Ingagwiritsidwenso ntchito popanga utoto, zolembera, chikopa chochita kupanga, inki yosindikizira, galasi lotetezera, cellophane, mafuta, mankhwala ophera tizilombo, zosungunulira zonunkhira, mafuta odzola nsalu ndi zofewetsa rabara, ndi zina zotero.

Mapulogalamu
Amagwiritsidwa ntchito ngati chowonjezera pa zokutira zoyendetsedwa ndi madzi kuti apititse patsogolo kupanga filimu
Magwiridwe antchito
Zowonjezera zopangira mafilimu, zopanga pulasitiki, zopanda poizoni komanso zopanda kukoma
1. Kufotokozera:
Kawirikawiri, emulsion imakhala ndi kutentha kopanga filimu, kutentha kozungulira kumakhala kotsika kuposa kutentha kopanga filimu ya emulsion, chopangira filimu ya emulsion chimatha kusintha makina opangira filimu ya emulsion ndikuthandizira kupanga filimu. Pambuyo popanga filimu, othandizira opanga filimuyo amasinthasintha, zomwe sizingakhudze mawonekedwe a filimuyo. Chogulitsacho chimakhala ndi kutentha kwambiri, magwiridwe antchito abwino kwambiri pachilengedwe, kusagwirizana bwino, kusinthasintha kochepa, ndipo n'chosavuta kuyamwa ndi tinthu ta latex. Chimatha kupanga filimu yabwino kwambiri yopitilira. Ndi chinthu chopangira filimu chomwe chimagwira ntchito bwino kwambiri mu utoto wa latex, chomwe chingathandize kwambiri mawonekedwe opangira filimu ya latex. Sichimangogwira ntchito pa acrylic yoyera, styrene-acrylic, acrylic acetate emulsion, komanso chimagwira ntchito pa vinyl acetate emulsion. Kuphatikiza pa kuchepetsa kwambiri kutentha kotsika kwambiri kwa utoto wa latex, chingathandizenso kuyanjana, kukana nyengo, kukana kutsuka ndi kukulitsa utoto wa latex, kuti filimuyo ikhale ndi kukhazikika kwabwino kosungira.
2. Magawo ogwiritsira ntchito:
A. Zophimba nyumba, zophimba zamagalimoto zapamwamba komanso zophimba zokonzanso, zophimba zozungulira
B. Chosungunulira chonyamulira nsalu chomwe chimagwira ntchito bwino posindikiza ndi kuyika utoto
C, ya inki, chotsukira utoto, zomatira, chotsukira ndi mafakitale ena
3. Kusungira ndi kulongedza:
A. Ma emulsion/zowonjezera zonse zimakhala zamadzi ndipo palibe chiopsezo cha kuphulika zikanyamulidwa.
B. 200 kg/chitsulo/ng'oma ya pulasitiki. 1000 kg/mphaleti.
C. Ma phukusi osinthika oyenera chidebe cha mamita 20 ndi osankha.
D. Chogulitsachi chiyenera kusungidwa pamalo ozizira komanso ouma, kupewa chinyezi ndi mvula. Kutentha kosungirako ndi 5 ~ 40℃, ndipo nthawi yosungira ndi pafupifupi miyezi 24.
