Dibutyl phthalate (DBP)
Dibutyl phthalate ipurasitiki ine simba rakasimba rekunyungudika kwemapurasitiki akawanda. Inoshandiswa mukugadzirisa PVC, inogona kupa chigadzirwa kupfava kwakanaka. Inogona zvakare kushandiswa mu nitrocellulose coatings. Ine kunyungudika kwakanaka, kupararira, kunamira uye kuramba mvura. Inogona zvakare kuwedzera kuchinjika, kuramba kuchinjika, kugadzikana, uye kushanda zvakanaka kwependi yependi. Inoenderana zvakanaka uye ipurasitiki inoshandiswa zvakanyanya pamusika. Yakakodzera marubha akasiyana-siyana, cellulose butyl acetate, ethyl cellulose polyacetate, vinyl ester nemamwe maresini ekugadzira semapurasitiki. Inogona zvakare kushandiswa kugadzira pendi, stationery, dehwe rekugadzira, inki yekudhinda, girazi rekuchengetedza, cellophane, mafuta, zvipembenene, zvinonhuwira zvinonyungudika, mafuta ejira uye rabha inonyorovesa, nezvimwewo.

Mashandisirwo
Inoshandiswa sechinhu chinowedzera pakuputira firimu mumvura kuti ikurumidze kuumbwa kwefirimu
Kushanda
Zvinowedzera kugadzira mafirimu, zvinogadzira purasitiki, hazvina chepfu uye hazvina kunaka
1. Tsananguro:
Kazhinji, emulsion ine tembiricha inoumba firimu, kana tembiricha yekunze yakaderera pane tembiricha inoumba firimu ye emulsion, emulsion film forming agent inogona kuvandudza muchina unoumba firimu ye emulsion uye kubatsira kugadzira firimu. Mushure mekuumba firimu, firimu rinoita kuti firimu rive rakasimba, izvo hazvizokanganisi hunhu hwefirimu. Chigadzirwa chacho chine poindi yekufashaira yakanyanya, kushanda zvakanaka kwezvakatipoteredza, kusawirirana kwakanaka, kusagadzikana kwakaderera, uye zviri nyore kunyudzwa ne latex particles. Inogona kugadzira firimu rinoenderera mberi rakanaka. Ifirimu rinoita kuti firimu rive rakasimba uye rinoshanda zvakanaka mu latex pendi, izvo zvinogona kuvandudza zvikuru mashandiro e latex pendi. Haingoshandi chete kune pure acrylic, styrene-acrylic, acrylic acetate emulsion, asiwo inoshanda kune vinyl acetate emulsion. Pamusoro pekuderedza zvakanyanya tembiricha inoumba firimu ye latex, inogona zvakare kuvandudza kubatana, kuramba mamiriro ekunze, kuramba kukwesha uye kukura kwemavara e latex pendi, kuitira kuti firimu rive nekugadzikana kwakanaka kwekuchengetedza.
2. Minda yekushandisa:
A. Kupfeka zvekuvaka, kupfekedza mota dzemhando yepamusoro uye kupfekedza kugadzirisa, kupfekedza zvinomonereka
B. Chinhu chinotakura zvinhu chisingakuvadzi nharaunda chekudhinda nekudhaya machira
C, yeinki, chinhu chinobvisa pendi, chinonamira, chinhu chinochenesa uye mamwe maindasitiri
3. Kuchengetedza uye kurongedza:
A. Zvese zvinosanganiswa nemvura uye hapana njodzi yekuputika kana zvatakurwa.
B. 200 kg/simbi/dhiramu repurasitiki. 1000 kg/pallet.
C. Kurongedza kunochinjika kwakakodzera mudziyo une 20 ft hakudiwi.
D. Chigadzirwa ichi chinofanira kuchengetwa munzvimbo inotonhorera uye yakaoma, kudzivirira hunyoro nemvura. Tembiricha yekuchengetera i5 ~ 40℃, uye nguva yekuchengetera imwedzi ingangoita makumi maviri nemana.
