Plasticizer yog ib lub ntiaj teb coob khoom plig rau ntau lawm thiab kev noj tshuaj.China tau dhau los ua tus tsim khoom loj tshaj plaws thiab kev noj cov yas rau hauv Asia.Yog kev txhim kho ntawm kev tshaj tawm thoob ntiaj teb, cov khoom yas xws li tshuaj thiab cov khoom noj khoom noj, cov khoom ua si thiab lwm cov khoom yas tau muab tso rau siab dua purity thiab kev xav tau tu kom zoo rau cov yas yasizers.Yog li ntawd, cov nram qab no yog cov khoom yas nrawm rau ntau tshaj cov kev cai:
1. Biodegradable plasticizer nroj tsuag roj raws li yas yas yog ib hom kev ua kom zoo, cov tshuaj tsis muaj teeb meem degradable plasticizer.Danish cov kws tshawb fawb tau siv cov roj zaub los tsim cov yas yas uas hloov ncaj qha rau cov tshuaj phthalic acid plasticizer, uas tau raug muag thiab siv hauv eu lub teb chaws.Thaum muaj ntau dua cov kev cai rau kev noj qab haus huv xws li polymer cov ntaub ntawv hu nrog zaub mov, cov khoom ua si thiab cov khoom kho mob, nws daim ntawv thov rau cov lag luam cap, muab lub xovtooj puab thawj zaug, thiab lwm yam kev sib deev thiab khoom noj khoom yas. biodegradable, txawm tias yog hais tias ua yuam kev mus rau hauv lub cev tsis muaj teeb meem, tuaj yeem siv los ntawm cov metabolism.
2. Citrate esters plastisers rau cog los ntawm fermentation zus ntawm citric acid li raw cov ntaub ntawv hauv synthesis ntawm citrate esters yas thiab thoob ntiaj teb tau pom tau hais no hom environmentally friendly PVC citrate plasticizer industrialized ntau lawm, cov khoom tau nkag mus hauv Teb Chaws Asmeskas, Nyiv, Teb chaws Europe thiab lwm cov kev lag luam. Tebchaws Asmeskas, European Union thiab lwm lub teb chaws tau tsim muaj kev tswj hwm, tso cai citric acid ester raws li cov menyuam cov khoom ua si, cov khoom tsis huv thiab lwm yam khoom muaj feem xyuam rau tib neeg lub cev thiab cov khoom kho mob ntawm cov yas yas ntxiv ntawm ib qho kev thov siab. Citric acid ester cov khoom ua ib lub chaw tshiab tiv thaiv yas yas yas, lub plawv insertion, yuav hloov cov tshuaj phthalic acid esters plasticizer, siv cov tshuaj pleev ib ce, cov khoom noj txhua hnub, cov khoom ua si, thiab lwm yam kev lag luam, kuj yog ib qho tseem ceeb tshuaj.
3. Epoxidation plasticizer hom loj: epoxy plasticizer epoxidized soybean roj, epoxy acetyl linoleic acid methyl ester, epoxy chaff butyl oleate, epoxy cicada chrysalis oleic acid butyl ester, epoxy soybean roj yuav ester, etc.It yog tsim rau daim ntawv thov cov khoom yas , cov khoom yas thiab khoom ntim khoom noj.
4. Polyester plasticizer ua ib lub hnab yas tshiab zoo tshaj plaws, polyester plasticizer muaj ntau hom kev siv ntau.Vim vim tias lub cev muaj roj molecular ntawm polyester plasticizer zoo heev rau PVC, nws muaj siab affinity thiab tsawg toxicity, low volatility, cov khoom siv roj ntsha, roj, tsheb sib txuas, cov khoom siv dej tsis zoo, cov khoom ua si, cov khoom siv mis nyuj, haus dej khov thiab cov roj gas, cov roj ua tsis taus, Lub tshuab yas polyester siv rau hauv roj hmab cov khoom, uas tuaj yeem tsim cov roj hmab kub resistant, roj resistant, anti-o thiab resistant, thiab txhim kho txoj kev kawm ntawm roj hmab.
