Dibutyl phthalate (DBP)
Dibutyl phthalate yog ib yam khoom siv ua kom cov yas yaj tau zoo rau ntau yam yas. Siv rau hauv kev ua PVC, ua rau cov khoom mos zoo. Nws kuj tseem siv tau rau hauv cov txheej nitrocellulose. Nws muaj kev yaj zoo heev, kev tawg tau zoo, kev nplaum thiab kev tiv taus dej. Nws kuj tseem tuaj yeem ua rau cov xim pleev xim muaj kev ywj pheej, kev tiv taus khoov tau zoo, kev ruaj khov, thiab kev ua kom cov yas ua haujlwm tau zoo. Nws muaj kev sib raug zoo zoo thiab yog ib yam khoom siv ua kom cov yas siv dav hauv kev ua lag luam. Nws tsim nyog rau ntau yam roj hmab, cellulose butyl acetate, ethyl cellulose polyacetate, vinyl ester thiab lwm yam khoom siv ua cov ...

Cov ntawv thov
Siv ua ib qho khoom ntxiv rau cov txheej txheem dej kom ua kom cov zaj duab xis sai dua
Kev ua tau zoo
Cov tshuaj ntxiv rau zaj duab xis, cov khoom siv yas, tsis muaj tshuaj lom thiab tsis muaj saj
1. Kev piav qhia:
Feem ntau, cov emulsion yuav muaj qhov kub thiab txias ntawm cov zaj duab xis, thaum qhov kub thiab txias qis dua qhov kub thiab txias ntawm cov zaj duab xis emulsion, tus neeg sawv cev ntawm cov zaj duab xis emulsion tuaj yeem txhim kho lub tshuab ua zaj duab xis emulsion thiab pab ua zaj duab xis. Tom qab ua zaj duab xis, cov khoom pab ua zaj duab xis yuav valuate, uas yuav tsis cuam tshuam rau cov yam ntxwv ntawm zaj duab xis. Cov khoom muaj qhov kub siab, kev ua tau zoo ntawm ib puag ncig, kev sib xyaw zoo, kev hloov pauv tsawg, thiab yooj yim rau cov khoom latex nqus tau. Muaj peev xwm ua zaj duab xis txuas ntxiv zoo heev. Nws yog cov khoom siv ua zaj duab xis nrog kev ua tau zoo heev hauv cov xim latex, uas tuaj yeem txhim kho kev ua tau zoo ntawm cov xim latex. Nws tsis yog tsuas yog ua tau zoo rau cov acrylic ntshiab, styrene-acrylic, acrylic acetate emulsion, tab sis kuj ua tau zoo rau vinyl acetate emulsion. Ntxiv nrog rau kev txo qhov kub thiab txias ntawm cov xim latex, nws kuj tseem tuaj yeem txhim kho kev sib koom ua ke, kev tiv taus huab cua, kev tiv taus txhuam thiab kev txhim kho xim ntawm cov xim latex, yog li cov zaj duab xis muaj kev ruaj khov zoo.
2. Cov teb thov:
A. Cov tshuaj pleev xim rau tsev, cov tshuaj pleev xim rau tsheb zoo thiab cov tshuaj pleev xim kho, cov tshuaj pleev xim dov
B. Ib puag ncig-phooj ywg tus neeg nqa khoom hnyav rau kev luam ntawv thiab zas xim
C, rau cov kua mem, cov neeg sawv cev tshem tawm xim, cov nplaum, cov neeg sawv cev ntxuav thiab lwm yam lag luam
3. Kev khaws cia thiab ntim khoom:
A. Txhua yam emulsions/additives yog dej ua thiab tsis muaj kev pheej hmoo ntawm kev tawg thaum thauj mus los.
B. 200 kg/hlau/yas nruas.1000 kg/pallet.
C. Cov ntim khoom yooj ywm uas haum rau 20 ft thawv yog xaiv tau.
D. Cov khoom no yuav tsum khaws cia rau hauv qhov chaw txias thiab qhuav, tsis txhob muaj dej noo thiab los nag. Qhov kub cia yog 5 ~ 40 ℃, thiab lub sijhawm cia yog li 24 lub hlis.
